DETAILED DESCRIPTION

[0137] With reference to FIG. 1, a front view of a first embodiment of the stimulation device 1 according to the invention is explained, with FIG. 2 showing a perspective view and FIG. 3 showing a cross-section of the stimulation device 1 according to the invention of the first embodiment.

[0138] The first embodiment of the stimulation device 1 is a, preferably portable, electric or small device, which has a housing 8, a stimulation head 4 for placing on the clitoris 12, a transition 5 between the stimulation head 4 and the housing 8, operating elements 71, an indicator 72, an on/off switch 74, an optional socket 75, an optional battery 76 and an optional lighting system 9.

[0139] The housing 8 is preferably designed ergonomically so that it can be held comfortably with one hand and has no sharp or pointed edges. Furthermore, the housing 8 can be made of a plastic, for example polycarbonate (PC) or acrylonitrile butadiene styrene (ABS). In addition, the grip areas or even the entire housing 8 can be supplemented or configured with a silicone that is advantageous to the touch, for example in the form of a silicone cover. The housing 8 is preferably at least water-repellent or splash-proof, for example protection class IP 24. Furthermore, the stimulation device 1 can be made waterproof against immersion to at least 0.5 m under water for at least 30 minutes. For this purpose, a transition 5 between the stimulation head 4 and the housing 8 can also be configured to be waterproof; for example, this can be a glued or press fit. In addition, the housing 8 has a longitudinal axis 80, which is an imaginary axis running longitudinally from a front end 90 to a rear end 91. Furthermore, the stimulation device 1 has an alignment axis 81 (in FIG. 1 leading in and out of the plane of the drawing), which indicates the main directions in which the deflections of the vibrations of the stimulation head 4 take place, which are provided for stimulating the clitoris 12.

[0140] The operating element 71 or the operating elements 71 are used to set the operating mode of the device, i.e. to set the stimulation by the stimulation head 4. The at least one operating element 71 may, for example, be configured as at least one pushbutton, as at least one rotary switch, or as at least one touch-sensitive switch. Furthermore, the at least one operating element 71 can provide optical feedback on the actuation, for example by means of light-emitting diodes (LED) integrated in the switch.

[0141] An optional indicator 72 serves to inform the user about the status of the device and/or the setting status. The indicator 72 can, for example, be equipped with a single light-emitting diode, a plurality of light-emitting diodes or as an LCD display. The information displayed can be, for example, the power-on status of the instrument, the charge level of an optional battery 76 or the current setting of the modulation pattern.

[0142] The on/off switch 74 is used to activate and deactivate stimulation device 1. This on/off switch 74 can be, for example, a pushbutton that switches the stimulation device 1 on or off when pressed for a long time, or a snap-in slide switch.

[0143] A socket 75 is used for the external power supply of stimulation device 1 via an external plug 73, which is connected to an external mains adapter, for example. In order to ensure that the stimulation device 1 is splashproof, instead of the socket 75 a magnetic-inductive transformer can preferably be provided which enables power to be transferred to the stimulation device 1 without an electrically conductive contact. Preferably, the stimulation device 1 also has a battery 76, for example a nickel-metal hydride (NiMH) or lithium battery, for wireless operation. Alternatively, a (longer) power supply cable 116 can be led out of the stimulation device. Alternatively, magnetic contacts can also be provided as a power supply connection.

[0144] An optional lighting system 9 is provided on or in the housing 8. The lighting system 9 is preferably used to illuminate the stimulation head 4. The lighting system 9 can either be switched on by the user or be activated automatically when the stimulation device 1 is activated. Furthermore, the lighting system 9 can be formed by at least one energy-saving LED. The lighting system can, for example, serve as an orientation aid for the user of stimulation device 1 in the dark or as additional optical stimulation.

[0145] FIG. 3 shows a cross-section of a drive device 6 of the stimulation device 1. The drive device 6 has a moving coil assembly 60, which has a pole core 61, a coil or moving coil 62, a moving coil carrier 63 (carrier), an air gap 64 between a permanent magnet 66 and the moving coil 62, and a suspension 65, preferably a centering spider or centering membrane. The air gap 64 is preferably configured to be as small as possible in order to provide high field strengths in it. Furthermore, the moving coil 62 is movably suspended by the suspension 65 in such a way that it can vibrate back and forth along an imaginary straight line, i.e. the moving coil 62 can perform a linear movement with its moving coil carrier 63, as indicated by the double arrow D in FIG. 3. The suspension 65 is preferably made of an impregnated fabric or of an elastic material and supports the moving coil carrier 63 and thus the moving coil 62. The suspension 65, when viewed from above, can preferably be circular with a central recess. A front pole plate 68a and a rear pole plate 68b are preferably made of steel. In summary, the movably suspended moving coil 62 is immersed in the magnetic field of at least one permanent magnet 66.

[0146] If the moving coil 62 is now energized via the supply line 67, Lorentz forces act on the moving coil 62, and the moving coil 62 will move with the moving coil carrier 63 according to the current supply. In other words, the moving coil 62 can be driven in such a way that it vibrates back and forth in the magnetic field of the moving coil assembly 60. An advantage of the drive arrangement 6 is that the generated vibrations can be generated very flexibly and with great dynamics. In addition, the generated vibrations can have complex stimulation patterns which, for example, have at least two frequency components or predetermined waveforms. In addition, with the drive device 6 shown, forces can also be generated that are sufficient to stimulate the clitoris 12. A further advantage is that the drive device 6 preferably has a frequency response that can be provided evenly (<6 dB, determination via an FFT as described above) in the frequency range relevant for stimulation. This makes it possible to operate the stimulation device with a simple control system and effectively over the entire frequency range provided. In addition, such a drive device 6 vibrates only linearly, and not in a plane in undesired directions, whereby the generation of disturbing natural vibrations is already reduced in principle.

[0147] The moving coil carrier 63 is further coupled to a vibrating element 3, which transmits the generated movement or deflection to the stimulation head 4. Consequently, the stimulation head 4 will vibrate back and forth along the alignment axis 81, with the vibrations being transmitted to the clitoris 12 and the underlying tissue when the stimulation head 4 is placed on top of it.

[0148] Furthermore, the transition 5 between stimulation head 4 and housing 8 is formed in such a way that it can compensate for the deflections of the stimulation head 4 relative to housing 8. The vibrating mass of the arrangement of FIG. 1 to 3 explained above can now be kept quite small (compared to a drive with an unbalance), since only the moving coil 62 with the moving coil carrier 63, the vibrating element 3 and the stimulation head 4 need to be moved, with the latter three elements preferably being able to be made of non-metallic materials, and preferably of low-density materials.

[0149] Furthermore, the cross-section of the moving coil 62 and/or the pole core 61 and/or the moving coil carrier 63 may be substantially circular, or the cross-section may be square, rectangular or otherwise shaped.

[0150] The stimulation head 4 preferably has a silicone covering which surrounds a head element 45 which, for example, consists of a foam or a soft plastic. However, the entire stimulation head 4 can also consist of silicone or rubber.

[0151] The stimulation device 1 thus has a linear electrodynamic drive capable of causing the stimulation head 4 to vibrate with deflections whose direction is indicated by the double arrow D.

[0152] A control device 7 with a control board 77 controls, among other things, the drive device 6, the operating elements 71 and the indicator 72. The control device 7 and the drive device 6 are supplied with power from the internal battery 76 and/or the external power supply 73. Furthermore, the control device 7 can be connected via an antenna 78 to an operating device (not shown in detail) which enables remote control of the stimulation device 1.

[0153] In this embodiment, a sensor device 783 is also provided, which has a measuring range 781 (given here as an example only), which is provided at or before the stimulation head 4 of the stimulation device 1a. In this measuring range 781, an approximation or the existence of a surface or a body part (positive) can be determined. In relation to the application of the stimulation device, the clitoris 12 is thus preferably detected with the surrounding skin areas.

[0154] When it is switched on, the stimulation device 1 is in standby mode. In this standby mode, the stimulation device 1 is in operation, i.e. for example, the control device 7 is working because the user has switched on the stimulation device 1, but the drive device 6 is de-energized so the stimulation device 1 does not produce any vibrations. In addition, the sensor device 783 is in standby mode and carries out measurements or estimates at regular intervals.

[0155] More specifically, a capacitive sensor can be used as sensor device 783, with at least one measuring electrode 782 of the sensor device 783 preferably being arranged inside the housing 8. For example, the capacitance or the change in capacitance of the measuring electrode 782 (i.e. the operating capacitance between the measuring electrode 782 and an approaching counter-electrode such as the human body as a grounded counter-electrode) can be determined by the sensor device 783 in order to carry out a measurement. Subsequently, it is determined, for example by means of a threshold value and by comparing this threshold value with the measured value obtained, whether or not there is an approach of the clitoris 12 to the stimulation head 4 of the stimulation device. If an approach of the clitoris 12 is determined, the sensor device 783 generates an activation signal, which is evaluated by the control device 7. The sensor device 783 and the measuring electrode 782 can also be provided on the control board 77.

[0156] If the control device 7 receives such an activation signal, the drive device 6 is energized or activated, which generates vibrations. In this case, the stimulation device is in active mode. Consequently, the stimulation device 1 changes its mode of operation from standby mode to active mode when the control device 7 receives the activation signal from the sensor device 783.

[0157] If the stimulation device 1a is now removed from the clitoris 12 and the clitoris 12 consequently leaves the measuring range 781, this information is also transmitted by the sensor device 783 to the control device 7. For example, the sensor device 783 can generate a deactivation signal and transmit it to the control device 7, or the transmission of the activation signal described above from the sensor device 783 to the control device 7 can be stopped. The stimulation device then changes its mode of operation from active mode to standby mode. For example, it may be that the user repeatedly puts down the stimulation device 1 during operation, for example to relax briefly, and then places the stimulation device 1 back on the clitoris 12. As a result, the stimulation device 1 is advantageously switched to silent mode during such pauses, since it is then in standby mode in which the drive device 6 is not active. Energy of the battery 76 is also saved.

[0158] Furthermore, the measuring electrode 782 can be configured in such a way that the resulting measuring range 781 of the sensor device 783 is positioned in front of the stimulation head 4 at the point intended for placement on the clitoris 12. The measuring range 781 can extend directly (as shown in FIG. 3) in front of the stimulation head 4 in such a way that an approach of the clitoris 12 is sensed when it enters the measuring range 781 (or the measuring window). In FIG. 3 the device is shown in a state before the clitoris 12 and the surrounding skin enters the measuring range 781, in which the clitoris can be sensed preferably positively.

[0159] Furthermore, the sensor device 783 may also transmit an output signal to the control device 7 depending on the measured value (for example, the value of the determined capacitance). This signal may be a voltage signal or a digital bus signal, for example. This signal can, for example, be used to control the amplitude of the vibration generated in such a way that when the stimulation head is brought closer to the skin area, the vibration amplitude is increased. A maximum value of the vibration amplitude can also be provided, so that the regulation of the vibration amplitude takes place between 0 and the specified maximum value or the maximum value set by the user. In other words, according to another aspect, the stimulation device's vibration generation can not only be activated (in the sense of a mere on/off switch), but can be increased from zero to the desired vibration amplitude. In this way, the stimulation device is started up advantageously gently. In addition, the above functionality can also be applied when deactivating, which allows the stimulation device to be switched off gently in the same way. Furthermore, other parameters of the vibration can be controlled or regulated accordingly, for example the frequency can be controlled additionally or alternatively to the amplitude. In addition, a predetermined control curve can be stored in the control device 7, the curve relating to at least one predefined parameter of the vibration as a function of the transmitted measured value of the sensor device.

[0160] In addition, the proximity of the body to the stimulation head 4 as a whole can also be determined, for example using a capacitive or acoustic measurement principle. If the user now presses the stimulation device 1 more firmly onto the clitoral glans 12, the stimulation head 4 is pressed into the skin to a certain extent, whereby the stimulation head 4 is (partially) surrounded by tissue at its front portion. This can also be detected with a sensor, for example the capacitance of a capacitive sensor which has a measuring range around the stimulation head 4 is changed. Based on these considerations, according to another aspect of the invention, the amplitude, frequency or even a frequency composition can be adjusted or controlled in dependence on a further measuring range. This measuring range can surround the stimulation head 4, for example in a ring shape, with the central axis of this ring preferably coinciding with the alignment axis 81. A measuring range can also be provided laterally next to the stimulation head 4. This can, for example, extend in a portion parallel to the lateral surface of the stimulation head 4.

[0161] The measuring electrode 782 according to the invention may further be arranged in the immediate vicinity of, or adjacent to the drive device 6.

[0162] In particular, the measuring electrode 782 according to the invention can be arranged in a ring or semicircle around the moving coil assembly 60, thus creating a measuring configuration which has a high measuring sensitivity in the sensor device 783 in the direction of the alignment axis 81 of the stimulation device. Thus, in this case, an imaginary surface of the ring-shaped measuring electrode 782 is perpendicular to the alignment axis 81 and is advantageously arranged approximately parallel to an imaginary skin surface of the clitoris 12.

[0163] In addition, a shielding electrode (not shown in greater detail) may be provided to shield the measuring electrode 782 from undesirable interference effects (for example from interference capacitances). For example, the shielding electrode can be positioned behind the measuring electrode 782 from the viewpoint of the stimulation head 4 of the stimulation device, so that, for example, a hand holding the device is not detected.

[0164] Alternatively, a sensor device 783 can be provided in such a way that contact of the clitoris 12 with the wall 41 is detected. For example, the measuring range 781 can be provided in such a way that the extent of the measuring range 781 in the direction of the alignment axis 81 is very small, for example 0.5 mm. In addition, a contact sensor can also be provided in the wall 41 as a sensor device 783. Such a contact sensor, for example a probe or a conductivity sensor with two measuring electrodes, can detect direct contact of the skin with the wall 41.

[0165] Furthermore, the stimulation device 1 according to the invention can have a heating element 79, which is arranged in the wall 41 in the form of a spiraled conductor, for example. Thus, the wall 41 or also the stimulation head 4 as a whole can be heated preferably to skin temperature. The heating element 79 can be activated by the user, for example by means of an operating element 71. Alternatively or additionally, the heating element 79 can be automatically energized after switching on the stimulation device 1, for example in standby mode. Furthermore, a temperature measuring unit (not shown in detail) is preferably provided on or in the stimulation head 4 for regulating and in particular limiting the temperature to the usual skin temperature of clitoris 12.

[0166] Additional developments for the stimulation device 1 are presented below. All the features, embodiments, aspects and developments of the stimulation device 1 disclosed here can be combined with each other as long as this is technically feasible for a person skilled in the art.

[0167] FIG. 4 shows a detailed representation of the drive device 6 of a further embodiment with a moving coil assembly 60. The same reference signs in FIG. 4 as in FIG. 1 to 3 denote identical or similar features with identical or similar functional properties. For this reason, the differences between the drive device 6 in FIG. 4 and the first embodiment are explained in greater detail below.

[0168] The moving coil assembly 60 is attached to the inside of the housing 8, which is made of ABS, for example. This attachment can be achieved by means of a screw connection, as shown, or by adhesive bonding (not shown). Furthermore at least one front stop element 69a (69c) is provided on the moving coil carrier 63 to limit the freedom of movement of the moving coil 62. If, for example, the stimulation head 4 is pressed towards the inside of the housing (i.e. downwards in FIG. 4), the front stop element 69a strikes the rear stop element 69b. If, conversely, the stimulation head 4 is pulled in a direction away from the inside of the stimulation device 1 (i.e. upwards in FIG. 4), the front stop element 69a strikes the front pole plate 68a. In such a design, the membrane 65 can be made of a material with usual (and not increased) strength, as potentially overloading forces are prevented by the stop elements (69a, 69b, 69c).

[0169] Furthermore, at least one holder 8a, for example in the form of a web or a fastening portion, is provided on the housing 8, on which holder the suspension 65 is provided. In this way, the suspension 65 can be advantageously fastened directly to the housing 8, which can absorb the forces which can act on the suspension 65. A head element 45 is provided on the planar vibrating element 3 and has a protruding shape or a convexly curved shape. This head element 45 preferably consists of a rigid plastic, for example ABS or PC, and optionally has at least one heating element 79 which serves to heat the stimulation head 4.

[0170] Furthermore, an outer layer 10, preferably made of an elastic material, is provided, which, for example, can at least partially surround the stimulation device 1 as a silicone layer and extends laterally from the housing 8 in such a way that it covers the stimulation head 4. The outer layer 10 in the area of the stimulation head 4 is preferably provided with a greater thickness than around it, whereby the stimulation head 4 is softer and more pleasant to the touch in the area intended to be placed on the clitoris 12. In addition, this layer 10 has a play or elasticity to compensate (in length) for the deflections of the vibrations of the stimulation head 4. Due to this outer (continuous) layer, the stimulation device 1 is advantageously sealed, at least at this point, and the ingress of dust or water into the interior of the drive device 6 is prevented. In addition, the measuring electrode 782 is provided adjacently to the moving coil assembly 60, and therefore the measuring range 781 can be provided advantageously in front of the stimulation head 4. For example, the measuring electrode is an at least largely ring-shaped capacitive measuring electrode 782. Furthermore, the stimulation head 4 can also be provided in one piece, for example made of silicone.

[0171] The stimulation head 4 as well as the moving coil 62 is moved along the alignment axis 81 (see also the double arrow D), which means that the vibrations can act directly on the clitoris 12 when the stimulation head 4 is placed thereon.

[0172] Furthermore, an impedance control ring 61a may preferably be provided on or at the pole core 61 to further improve the electrodynamic properties of the moving coil assembly 60. The inductance of the moving coil causes its impedance to rise as the frequency of the drive signal increases. The impedance control ring can reduce or compensate for this effect.

[0173] FIG. 5 shows a detailed representation of the drive device 6 according to the invention in accordance with a further embodiment with a moving coil assembly 60. Identical reference signs in FIG. 5 as in FIG. 1 to 3 denote identical or similar features with identical or similar functional properties. For this reason, in particular the differences between the drive device 6 in FIG. 5 and the first embodiment are explained in greater detail below.

[0174] The stimulation head 4 of FIG. 5 is arranged exchangeably (preferably by means of a clamp fit) and is also divided into a front portion 42 and a rear portion 43. For example, the rear portion 43 is made of silicone, which can be engaged with a lateral engagement 31 of the vibrating element 3 to attach the stimulation head 4 to the vibrating element 3. The front portion 42 is made of a very soft material, for example with a compressive modulus of elasticity lower than 0.1 N/mm.sup.2, preferably lower than 0.05 N/mm.sup.2, in particular lower than 0.01 N/mm.sup.2, and comprises the heating element 79. This improves the haptic properties of the stimulation head 4.

[0175] A one-piece, exchangeable stimulation head 4, preferably made of silicone, may also be provided.

[0176] FIG. 6 a) to e) show detailed representations of drive devices 6 according to the invention according to further aspects, each with a moving coil assembly 60. Identical reference signs as in FIG. 1 to 3 denote identical or similar features with identical or similar functional properties. Therefore, in particular the differences between the drive device 6 of FIG. 6 a) to e) and the first embodiment are explained in detail below.

[0177] Referring to FIG. 6 a), the stimulation head 4 is again exchangeable, although it may be made in one piece, for example from rubber. Furthermore, a stop element 69c is provided which is mounted on a rod or pin extending along the alignment axis 81 of the pole core 61. Furthermore, a vibrating element 3 is provided which has a cavity in which the stop element 69c is provided. The vibrating element 3 has a freedom of movement which is determined by the length of the cavity. If the stimulation head 4 is pulled or pressed too tightly, the stop element 69c strikes one of the sides of the cavity. Furthermore, a guide 69d is provided to prevent excessive tilting of the moving coil carrier in the moving coil assembly, with a through-hole, for example a hole with a circular cross-section, possibly being provided in the vibrating element 3 for the rod. The guide 69d can be arranged in such a way that it can slidably receive the rod (connected to the pole core 61). In addition, the guide can be provided with a lubricant, for example silicone oil. The guide can also be configured in such a way that the friction losses are as low as possible, for example self-lubricating and/or low friction loss materials can be used. It is also possible to provide a larger clearance (for example more than 1 mm) with regard to a tilting of the stimulation head 4, as this is sufficient to prevent damage, particularly to the suspension 65. In this way, excessive tilting of the stimulation head 4 can be prevented, thus avoiding damage to the suspension 65, the moving coil carrier 63 and/or the moving coil 62.

[0178] In addition, the vibrating element 3 may have a mushroom-like shape, which has a circumferential engagement 31 for the stimulation head 4, whereby the stimulation head 4 can be easily attached to or removed from the vibrating element 3.

[0179] FIG. 6 b) shows a modification of the aspect of FIG. 6 a). Here too, an exchangeable stimulation head 46 is provided, which can be easily attached to the stimulation device 1 and removed from it again by means of a shape adapted to an engagement 31 (for example a projection). In this way, exchangeable stimulation heads 4, 46 can be provided that are adapted to the anatomy of the user or to the user's presence.

[0180] In this aspect, a guide 69d can also be optionally provided to increase the mechanical robustness of the arrangement.

[0181] In addition, compared to FIG. 6 a), further stop elements 69e1 and 69e2 are provided. The stop element 69e1 is provided on the moving coil carrier 63 and is preferably made of a plastic material (for example a material with a low density so as not to impair the dynamics of the moving coil assembly). In addition, a further stop element 69e2 is provided which is arranged at a distance from the stop element 69e1 via a gap. The stop element 69e2 can also be made of a plastic material. In particular, the stop elements 69e1 and 69e2 may consist of a soft and/or elastic material, for example foam or rubber. A material with self-lubricating properties can also be used as the material of the stop elements 69e1 and 69e2, which reduces the possibility of the arrangement becoming wedged. Furthermore, the stop elements 69e1 and 69e2 may be arranged in such a way that their opposite end faces are parallel to each other, while the edges of at least the stop element 69e1 are chamfered or rounded in order to reduce possible abrasion or grinding marks. Furthermore, the stop elements 69e1 and 69e2 may be provided as rings completely surrounding the pole core, which is easy to manufacture, or the stop elements 69e1 and 69e2 may also be provided only in portions in order to save weight.

[0182] If a force acts laterally on the stimulation head 3, the moving coil carrier 63 can tilt laterally with respect to the pole core 61 and possibly tilt, which is undesirable as the mechanics and especially the suspension 65 may be damaged. More specifically, it can be assumed that approximately at the level of the suspension 65 there is a mechanical pivot point of the suspended arrangement with respect to forces acting laterally on the stimulation head 4, which means that in the event of a lateral load on the stimulation head 4, especially the lower end of the moving coil carrier 63 can also be deflected laterally. Under certain circumstances, the stimulation head 4 can also be used to exert a detrimental leverage effect on the moving coil assembly 60. However, such a deflection can be limited by means of the two complementary stop elements 69e1 and 69e2, thus preventing damage. In addition, the stop element 69e1 also counteracts an excessively firm depression of the stimulation head 4, since in this case the stop element strikes against the lower pole plate 68b.

[0183] It should be noted that the stop elements 69e1 and 69e2 may also be provided without a stop 69c together with its associated pin and also without a guide 69d in order to provide a stop against tilting or depression of the stimulation head 4 and the moving coil carrier 63 with respect to the simulation device 1.

[0184] FIG. 6 c) shows another aspect of a moving coil assembly 60 that can reduce the risk of damage (as explained above). This can be achieved in particular by forces acting laterally on the stimulation head 4.

[0185] Instead of at least one stop, as in the aspect of FIG. 6 a), a further suspension 65a is provided in this case, which (like or similarly to the suspension 65 described above) provides a further bearing for the moving coil carrier 63. The further suspension 65a may in particular consist of a non-magnetic material, for example an elastomer, so as not to impair the magnetic field and thus the function of the drive. In particular, an impregnated fabric or a membrane made of a fluoroelastomer can be used.

[0186] This double bearing of the moving coil carrier makes it possible to avoid tilting without increasing the weight of the movably suspended arrangement too much, thus achieving sufficient dynamics of the moving coil assembly 60 while maintaining mechanical robustness.

[0187] Moreover, the use of two suspensions 65, 65a improves the mechanical robustness of the stimulation head 4, even when it is pushed in or pulled out, as the forces exerted can now be absorbed by two suspensions 65, 65a.

[0188] Another possibility to increase the mechanical robustness of the moving coil assembly 60 is shown in the related FIGS. 6 d) and 6 e). FIG. 6 d) shows, in particular, the pole plate 68b, extensions 63a of the coil carrier 63, a suspension 65, another suspension 65b and a housing receptacle 8b in a side view (see 11 in the circle with arrow in FIG. 6 e) for the direction of view). FIG. 6 e) shows a bottom view (see I in the circle with arrow in FIG. 6 d) for the direction of view) of only the lower pole plate 68 b) and the extensions 63a, the other elements of FIG. 6 d), for example the suspension 65b and the housing receptacle 8b, having been omitted for reasons of clarity.

[0189] Thus, similarly to FIG. 6 c), two suspensions 65, 65b, or centering spiders are provided for this aspect as well, which together counteract both excessive deflection along the axis 81 and excessive lateral deflection (for example in a left-right direction in the plane of the paper of FIG. 6 d), since there are now two suspension points for the coil carrier 3. The further suspension 65b is provided outside the radial area of the pole core 61, which simplifies production and further improves the mechanical robustness, as the distance between the suspension points of the two suspensions 65, 65b is increased compared to the aspect of FIG. 6c. More specifically, with the construction of this aspect, forces acting laterally on the stimulation head 4 can be better absorbed. In addition, suspensions 65, 65b of the same size can also be used advantageously, which simplifies the production.

[0190] Furthermore, the lower pole plate 68b of FIGS. 6 d) and 6 e) is provided with two openings 68c so that two extensions 63a of the moving coil carrier 63 can pass through them. The suspension 65b is attached to these extensions 63a.

[0191] However, more than two extensions 63a and corresponding openings 68c may also be provided, for example four or eight. This can further improve the mechanical robustness. The lower pole plate 68b, for example, can also be square or oval in shape, in contrast to FIG. 6 e). In the same way, just a single opening 68c in the lower pole plate 68b may also be provided for the passage of a single extension 63a.

[0192] The precise determination of the number of openings 68c (and the corresponding extensions 63a) is a trade-off between the mechanical stability caused by increasing the number of extensions 63a and the obstruction of the magnetic flux in the lower pole plate 68b through the openings 68c. Two or three openings 68c are preferred.

[0193] FIG. 7 a) to 7 e) show examples of different stimulation patterns according to the invention and the temporal profiles of vibrations of the stimulation head 4. These stimulation patterns are represented in an idealized way. In particular, the amplitude of the vibration can also depend on the pressure of the stimulation device 1 on the clitoris 12. The vertical axis of these FIG. 7 a) to 7 e) indicates the deflection of the stimulation head 4 and amplitude along the alignment axis 81 caused by the drive device 6 to an imaginary position on the alignment axis 81. The zero line or horizontal axis preferably indicates the rest position of the stimulation head 4. However, a rest position can also deviate from the displayed zero line; in particular, the zero line can also be shifted vertically. This can be the case, for example, if the drive device 6 is supplied with an AC voltage with a DC component.

[0194] Here FIG. 7 a) shows a simple (co-)sinusoidal vibration which can be generated, for example, by controlling the drive device 6 with a (co-)sinusoidal excitation current as the control pattern.

[0195] FIG. 7 b) shows a sawtooth-shaped stimulation pattern, which is a specific variant of a triangular stimulation pattern. The stimulation head 4 is moved away from the clitoris 12 at a nearly constant speed and then abruptly moved towards it. This leads to a more intense stimulation experience, whereby under certain circumstances a tingling sensation can be created. One reason for this is the sudden (abrupt) change in speed of the stimulation head 4, which is not present in a sinusoidal stimulation pattern, for example.

[0196] Thus, it was a further finding of the present inventor from experiments with a stimulation device with a dynamic and linear drive according to the invention that the clitoris 12 can differentiate between different vibrations, i.e. for example vibration frequencies, vibration amplitudes, vibration patterns, due to the presence of a multitude of nerve cells. The clitoris 12 has up to approximately 8,000 nerves and sensory cells, such as mechanoreceptors, also known as Vater-Pacini corpuscles, for vibration or vibration sensation and Meissner corpuscles for touch sensation.

[0197] Correspondingly, the mechanoreceptors of the Vater-Pacini corpuscles of the clitoris 12 can be stimulated with trained stimulation patterns, which can convey a vibration sensation to the user particularly well. The Vater-Pacini corpuscle belongs to the rapidly adapting receptors. It reacts to (positive and negative) acceleration and is therefore suitable as a vibration detector. According to medical findings, the highest sensitivity of these cells is at a vibration around 300 Hz, at which a deformation of a few micrometers is sufficient to excite the receptors. Concerning clitoral stimulation, experiments by the present inventor have shown that there is a good stimulation effect with frequencies up to approximately 170 Hz. Furthermore, stimulation patterns with frequency mixes can lead to different stimulation experiences of the user, which is advantageous. Thus, with the stimulation device according to the invention, it is now possible to create an improved stimulation experience.

[0198] A sawtooth-shaped stimulation pattern further leads to further frequency components in the stimulating vibrations that can be felt.

[0199] The sawtooth pattern can also be reversed, with an abrupt path movement and slower outward movement of the stimulation head 4. Similarly, stimulation can be performed with a triangular stimulation pattern that has a similar stimulation effect.

[0200] FIG. 7 c) shows vibrations or deflections of the stimulation head 4 which are the result of the addition of two fundamental vibrations with different amplitude and frequency. Preferably, it is the first harmonic added to a fundamental vibration. Such a multi-frequency vibration can provide an alternative, improved stimulation experience. For example, a fundamental frequency suitable for clitoral stimulation can be approximately 80 Hz.

[0201] FIG. 7 d) shows a stimulation pattern that has a complex sequence of vibrations. Similarly to a piece of music, a stimulation pattern can be composed, which can offer a varied stimulation experience. Such a stimulation pattern can, for example, be stored in the control device 7 in the form of an audio file and can be called up by the user as desired.

[0202] FIG. 7 e) shows an (idealized) square wave, which has very many frequency components. With such a stimulation, a stimulation effect with a multi-frequency stimulation of the clitoris 12 can be achieved.

[0203] The terms vibration and vibrations are used synonymously herein. According to the invention, vibrations are described as repeated temporal changes of at least one state variable of stimulation device 1. For example, and preferably, this is the recurrent deflection of the stimulation head 4 of the device 1 according to the invention.

[0204] FIG. 8 shows a block diagram of an example of a functional structure of an embodiment of the present invention with a control device 7, a drive device 6, a lighting system 9, an on/off switch 74, at least one operating element 71, a battery 76 and an external power supply 73. This basic structure of the control device 7 can be applied, in essence, to all disclosed aspects and embodiments. Furthermore, an antenna 78 (or an alternative communication device) is provided to communicate with a remote control device 2.

[0205] The control device 7, which, for example, has a microcontroller or is hard-wired, first of all controls the power supply of all consumers of the stimulation device 1, as well as optionally a charging and discharging process of the battery 76 and/or a battery management system. In particular, the control device 7 controls the excitation of the drive device 6, for example the magnitude of the deflection, the frequency, the modulation, etc.

[0206] Furthermore, the control device 7 can optionally have a memory, in which there is stored at least one modulation or stimulation pattern (these will be explained in greater detail in conjunction with FIG. 7 a) to 7 e). The drive device 6 can now be controlled according to these prestored stimulation patterns by the user of stimulation device 1 using the operating elements 71. The stimulation patterns can optionally also be individually created and stored by the user via the operating elements 71 or via the remote control device 2. For example, the remote control device 2 can have a program for creating your own stimulation patterns (or waveforms).

[0207] FIGS. 9 and 10 show a second embodiment of the stimulation device 1, which has an extension 140 intended for insertion into the vagina, for example in the form of a dildo. The extension 140 is preferably connected to the main body of the stimulation device 1 via a flexible connection 141, for example an elastic joint made of silicone. This allows the stimulation device 1 to be bent apart in the direction of the double arrow E. Furthermore, FIGS. 9 and 10 show a front visible edge of the stimulation device 1 by a dotted line. Furthermore, the stimulation device 1 is preferably provided with an outer (for example silicone) layer 10. On one side of the main body at least one operating element 71 and one indicator 72 are provided.

[0208] FIG. 9 shows the stimulation device 1 in a state in which it is not used on the body. FIG. 10 shows the stimulation device 1 in a state in which it is inserted vaginally via the extension 140 and the main body outside the human body rests on the clitoris 12 via the stimulation head 4. The stimulation device 1 is dimensioned in such a way that the main body, with its stimulation head 4, can rest on the outside of the clitoris 12 while the extension 140 is simultaneously inserted vaginally. The vaginal entrance is located at the point of the, preferably flexible, connection 141.

[0209] Furthermore, the stimulation device 1 of the second embodiment is preferably configured in such a way that, after bending apart and inserting stimulation device 1, forces F1 and F2 act as indicated by the corresponding arrows in FIG. 10. This ensures that the stimulation heads 4 and 4a rest well on the skin. With the clamping effect shown, the stimulation device 1 can also hold itself in place under certain circumstances without having to be held in place using the hands. Furthermore, the connection 141 is preferably tapered in relation to the extension 140 and the main body in such a way that the stimulation device 1 can be used during sexual intercourse (penetration).

[0210] The stimulation device 1 has (at least) two linear drive devices 6 (not shown in detail) according to the invention for stimulation, which have already been described in detail above. Furthermore, the stimulation heads 4 and 4a are integrated into the surface of the stimulation device 1. For this purpose, for example, the vibrating element 3 can be provided directly under the (outer) silicone layer 10.

[0211] Two alignment axes 81 and 81a are provided in such a way that they point to the same body region in the inserted state. The clitoris 12 is an organ which also occupies considerable space under the clitoral glans. Accordingly, the second embodiment of the stimulation device 1 can exert a stimulating effect on the clitoris 12 from two sides, since the vibrations generated spread into the clitoral region from two sides and thus improve the stimulation effect. In addition, the vagina is also stimulated with the vibrations according to the invention.

[0212] It will be appreciated that this embodiment can also be modified in such a way that it only has one linear drive device 6. Furthermore, in this case a further unbalanced excited vibration generation can also be provided.

[0213] In the following, with reference to FIG. 11 a) a side view of a stimulation device 1 according to the invention in accordance with a third embodiment and, with reference to FIG. 11 b), a sectional view of a stimulation device according to the invention in accordance with the third embodiment are shown. Identical reference signs in FIGS. 11 a) and 11 b) as in other figures, in particular FIG. 1 to 3, denote identical or similar features with identical or similar functional characteristics, therefore the differences between the drive device 6 of FIGS. 11 a) and 11 b) and that of the first embodiment are explained in greater detail below.

[0214] An elongate pen-shaped (or wand-shaped) housing 8, which is shown in FIG. 11 a), extends along a longitudinal axis 80 and has the stimulation head 4 at the front end 90. Such a housing form has advantages in terms of handling when stimulating the clitoris 12. The stimulation head 4 is provided at the front end 90 of stimulation device 1. Furthermore, the longitudinal axis 80 and the alignment axis 81 coincide, which makes operation easier, as users are used to guiding a pen. A head element 45, for example made of silicone, has a coating 44 which improves the surface quality of the stimulation head 4 of stimulation device 1. Furthermore, a moving coil assembly 60 is provided as the drive device 6, which is similar in respect of its components and function to one of the moving coil assemblies 60 of FIG. 3 to 6. For example, the moving coil assembly 60 has a moving coil, pole plates, an air gap, etc. Identical reference signs also denote identical or similar components here, and therefore a more detailed description of these can be omitted here.

[0215] The longitudinal axis of the housing of the stimulation device according to the invention is an imaginary axis extending from a front end of the elongate housing to a rear end (axially spaced from this front end) of the elongate housing. Preferably, the longitudinal axis is parallel to the length of the housing.

[0216] Usually, but not exclusively, the longitudinal axis may be an axis running lengthwise to the longest extent of the stimulation device.

[0217] For example, the longitudinal axis corresponds to the direction of the greatest total extent of the housing.

[0218] To fix a cuboidal and hollow cap 85, snap-in catches 862 are provided, which engage when the cap 85 is pushed over the front end 90 and over the middle portion 88 of the housing 8 until the stop edges 861 and 851 are in mutual contact. The cap 85 is shown in FIG. 11 a) arranged next to the housing 8, merely for simplification.

[0219] The center of mass MA of the stimulation device 1 is located in the rear portion 86, which makes said device easier to handle. Furthermore, the center of mass MA is preferably configured so that it is located on the longitudinal axis 80. This also improves the handling of the stimulation device 1, as lateral tilting moments are reduced or avoided. Furthermore, the position of the center of mass MA explained above could also be balanced or adjusted with additional (small) weight elements inside the housing 8.

[0220] The longitudinal axis 80 represents an axis of symmetry for the cap 85, for the rear portion 86 and for the middle portion 88.

[0221] For example, the housing 8 is about 4 cm wide (reference sign C), and about 12 cm long (reference sign A). Alternatively, the housing 8, for example, is about 3 cm wide (reference sign C) and about 12.5 cm long (reference sign A). Thus, during the development of the stimulation device, it has been shown that the resulting internal volume of the housing 8, with the alternative dimensioning of the housing 8 above, has just enough space to accommodate the components (motor, battery, control device, etc.) of the stimulation device 1.

[0222] Referring to FIG. 11 b), which shows, from the front, a sectional view of the stimulation device 1 (or rather, on the left side of FIG. 11 b) the housing 8 and on the right side of FIG. 12 b) the cap 85), the outer contour of the middle portion 88 and the stimulation head 4 of the stimulation device 1 can be seen.

[0223] The cap 85 according to the invention preferably has a square basic cross-section, which is slightly convex.

[0224] On the rear side of the housing 8 (not shown in detail), an on/off switch 74 with an associated illuminated ring 72 as indicator is provided centrally within a set-back or recessed end face 863. Furthermore, a socket 75 is provided for the connection of a power supply. This socket 75 can be closed with an appropriately sealing stopper.

[0225] The following FIG. 12 a) to 16 b) show further advantageous embodiments or aspects of a pen-shaped stimulation device 1 of the third embodiment.

[0226] FIGS. 12 a) and 12 b) show an elongate and rod-shaped stimulation device 1 with a housing 8 (for example made of ABS plastic), a front end 90, and a rear end 91, the stimulation device 1 being circular in its cross-section or in the outer contour in its cross-sectional plane. An on/off switch 74 is provided in the rear end, which optionally has a light element for indicating the switched-on state. An optional indicator 72 can show the current setting of the modulation pattern or the strength of the stimulation. A middle portion 88 is optionally coated with silicone, while a grip surface 89 (and another grip surface 89 on the opposite side, which is not shown in detail) in the form of an elongate oval surface (for example as a superellipse) indicates the preferred support position for the fingers and ensures a good grip of the fingers. These grip surfaces 89 may, for example, be color-coded, or an additional rubber coating may be applied to the surface of the middle portion 88.

[0227] A cup-shaped cap 85 complementary to the front end 90 or matching in shape is configured in such a way that it can be attached to the front end 90 in a manner similar to the cap of a pen. When fitted, the cap 85 covers (and protects) the front stimulation head 4 of the stimulation device 1 and extends longitudinally as far as the transition 5 or the interface of the wall 41 at the front end 90 to the middle portion 88.

[0228] Preferably, the outer diameter of the cap 85 in the transverse direction is equal to the outer diameter of the housing 8 in the transverse direction.

[0229] The stimulation head 4 of the stimulation device 1 is located in the front end 90, with the longitudinal axis 80 passing through the stimulation head 4. The directions front and rear are indicated accordingly in the drawing by the arrows. The front end 90 is the active end used for stimulation.

[0230] The on/off switch 74 can preferably be recessed in the housing 8 so that it does not protrude from the housing 8.

[0231] The longitudinal axis 80 is an imaginary line between the front end 90 and the rear end 91, which in the case of FIG. 7 a) and FIG. 7 b) also represents the axis of symmetry for the basic shape of the housing 8. These symmetry considerations do not take into account, for example, an on/off switch 74, indicators 72 or grip surfaces 89, which represent only minor adaptations of the basic shape of housing 8.

[0232] An alignment axis 81 can also cut the longitudinal axis 80 preferably at an angle of approximately 30 degrees, which further improves the handling.

[0233] Thus, the stimulation device 1 according to the invention has a compact, elongate and slim design. This leads to weight savings and ergonomic handling of the stimulation device 1. Preferably, the stimulation device 1 of FIGS. 12 a) and 12 b) is waterproof (IP67). For this reason and because of the simple external shape of the stimulation device 1, it is easy to clean.

[0234] Referring to FIG. 13 a) a side view of a stimulation device according to the invention, and referring to FIG. 13 b) a view of the stimulation device of the invention of FIG. 13 a) from behind is explained in greater detail.

[0235] The second embodiment has a regular hexagonal housing 8, which has a flat rear end 91. This allows this housing 8 to be placed or even laid down without rolling away. The shape of the housing thus serves as a roll stop. The on/off switch 74 and the indicator 72 are located adjacently to the front end 90. The cap 85 has a design similar to the first embodiment and fits the shape of the housing 8 of the second embodiment accordingly.

[0236] With reference to FIG. 14 a) a side view of a stimulation device according to the invention in accordance with a third embodiment, and with reference to FIG. 14 b) a view of the stimulation device according to the invention of FIG. 14 a) from behind is explained in greater detail.

[0237] The housing 8 of this embodiment is waisted in the middle for example, and tapers accordingly towards the middle. The two thickenings or bulges on the left and right of the central taperviewed in the longitudinal direction of the housing 8preferably both have the same maximum radius in the transverse direction. The housing 8 thus has a shape similar to a dog's bone.

[0238] The cross-sectional shape of the housing 8 is approximately oval, and is preferably maintained with the same width/height ratio over the entire length of the housing 8. This means that the housing 8 fits comfortably in the hand and does not roll away easily when the stimulation device 1 is removed.

[0239] The middle portion 88 also forms the grip surface 89 over its entire surface, preferably with a rubber-like or latex-like coating 44 being provided. This coating 44 can improve the haptic feeling of the stimulation head 4.

[0240] Furthermore, the middle portion 88 is formed over large parts of the housing 8 in the longitudinal direction. In synergy with the waisted design of the housing 8, this leads to an ergonomic handling of the housing 8, as the housing 8 comes to rest in the slim area in the middle at or on the hand when the housing 8 is guided like a writing instrument. In addition, the thumb and index finger rest against the front thickening of the housing 8 in this grip position, which is more ergonomic.

[0241] In addition, the stimulation device 1 has the thickening or knob-like cross-sectional enlargement at the rear end 91. This has the advantage that the stimulation device 1 has a kind of knob or button at the rear end 91, at which the stimulation device 1 can be held comfortably in a closed hand (for example in a first position), which is also an ergonomic hand position.

[0242] Alternatively, the thickening of the housing 8 at the rear end 91 may have a larger maximum radius in the transverse direction, similarly to the front thickening.

[0243] The cap 85 is configured analogously to the first embodiment, and fits the housing shape of the housing 8 of the third embodiment accordingly.

[0244] The angle of intersection between the alignment axis 81 and the longitudinal axis 80 can preferably be an acute angle. Preferably, this angle is about 3 to 12 degrees, which, according to experiments, has generally proven to be a pleasant angle range for the user for handling.

[0245] With reference to FIG. 15 a) a side view of a stimulation device according to the invention is explained in greater detail, and with reference to FIG. 15 b) a view of the stimulation device according to the invention of FIG. 15 a) from behind is explained in greater detail.

[0246] FIG. 15 a) shows a housing 8 which is triangular in cross-section and elongate. Preferably the outer shape is configured with the same thickness in the cross-sectional direction to save material and weight. On the one hand, this allows a very light and compact housing to be realized, while on the other hand a triangular housing of the same thickness fits well with the anatomy of holding the housing 8 with the thumb and index finger like a writing instrument, and is therefore ergonomic.

[0247] The on/off switch 74 is again recessed in the rear end 91 of housing 8, so that the stimulation device 1 can be placed upright on a table, for example, via the flat rear end 91.

[0248] The grip surfaces 89 (one of which is not shown in detail because it is concealed on the opposite side of the triangle of even thickness) are elongate oval, and are arranged in such a way that they represent the contact surface of the fingers on the housing 8 when the housing 8 is guided in the manner of a writing instrument. The two grip surfaces 89 are thus asymmetrically arranged. The grip surface 89 shown in FIG. 10 a) is intended for the thumb of a left-handed person. The grip surface (not shown in greater detail) would be arranged in an elongate oval shape on the other side of the triangle, more in the direction of the longitudinal axis 80 of the housing 8, corresponding to the (imaginary) position of an index finger. In this way, the grip surfaces can be adapted to the anatomy of the hand and the fingers of the user (particularly preferably according to whether she is right- or left-handed).

[0249] In addition, the grip surfaces 89 can also be configured as trough-shaped recesses in the middle portion 88. Alternatively, the grip surfaces 89 can have corresponding rubber coatings to improve the gripping of the device.

[0250] The cap 85 according to the invention is configured analogously to the first embodiment, and fits the housing shape of the housing 8 of the third embodiment accordingly and continues the housing shape in the direction of the longitudinal axis 80.

[0251] With reference to FIG. 16 a), a side view of a fifth embodiment of a stimulation device according to the invention, and with reference to FIG. 16 b) a view from the rear of the stimulation device according to the invention of FIG. 16 a) is explained in greater detail.

[0252] In the fifth embodiment, the outer contour of the cross-section changes at the transition 5 between the middle portion 88 and a rear portion 86. The middle portion 88 is preferably triangular in cross-section with rounded corners or edges (in particular of the same thickness; alternatively, the middle portion 88 of this configuration may also be round or oval). The rear portion 86 is preferably rectangular or square in cross-section (alternatively, it may be quadrangular or spherical; the latter results in the formation of a spherical or button-shaped retaining knob at the rear end 91 of the stimulation device 1). Preferably, those parts that are heavy or have a high weight are arranged in the rear portion 86 of the housing 8, for example the battery 76. This allows the center of mass MA of the housing 8 of the stimulation device to be placed further back in the direction of the rear end 91, which leads to better handling.

[0253] The ratio of length A to width B (which is equal to height C) of the housing 8 preferably is >3.5 (three point five), especially 3.9 (three point nine). Due to this elongate design, the housing 8 is easier to handle and more ergonomic.

[0254] The indicator 72 is located at the rear end 91 of the housing 8 in the form of an LED display surrounding the on/off switch 74. The user thus intuitively associates the display of the power-on status with the associated on/off switch 74 and vice versa.

[0255] Thus, the fifth embodiment is preferably characterized in that the outer contour of the housing 8 changes from the middle portion 88 to the rear portion 86. In other words, this aspect is preferably characterized in that the middle portion 88 has a different outer contour as compared to the rear portion 86.

[0256] Compared to the caps 85 of the first to fourth embodiments, the cap 85 of the fifth embodiment is longer. Thus, when the cap 85 of the fifth embodiment is fitted on the housing 8, not only the front end 90 is covered with the wall 41, but also the middle portion 88. Thus, the stop 851 of the cap 85 strikes the stop 861 of the rear portion 86 when the cap 85 is fitted on the housing 8. When the cap 85 is fully inserted, the stimulation device 1 has a uniform, elongate cuboidal appearance, which makes it impossible to see at first glance what the purpose is of the stimulation device 1 contained therein. In this respect, with the present discreet, light and compact design of the stimulation device 1, the stimulation device 1 can, for example, be carried discreetly and hygienically in a handbag.

[0257] In this aspect of the third embodiment, the alignment axis 81 can preferably coincide with the longitudinal axis 80, i.e. these are preferably arranged coaxially to each other.

[0258] FIG. 17 shows a system with one of the embodiments according to the invention of the stimulation device 1. It is noted that the system presented below can also be combined with the first or second embodiment. For example, a holder 110 has at least two fork-shaped holding arms 111, in which the stimulation device 1 is placed. The holding arms 111 are connected via holding legs 114 to a holder foot 115, which is preferably smooth and flat. In at least one of the holding legs 114 there is a charging coil or inductor 112 on the holding side. Correspondingly, the stimulation device 1 according to the invention has a charging coil or inductor 113 on the stimulation device side. If the stimulation device 1 is placed in the holding arms 111, a (known) inductive coupling between the stimulation device and an electronic power device (not shown in detail) can take place via the (preferably paired) coils. In this way, a battery 76 of the stimulation device 1 can be charged in wired fashion or wirelessly without the need for a socket or a connection to or in the housing 8. This simplifies, for example, a waterproof design of the housing 8.

[0259] FIG. 18 shows an alternative system with a holder 110 for charging the stimulation device 1 according to the invention. Here, the charging coil or inductor 113 on the stimulation device side can be located advantageously in the rear end 91 of the stimulation device 1. This facilitates a suitable weight distribution and adjustment of the center of mass MA of the stimulation device 1. In addition, (favorable) coils are preferably circular in shape, whereby they can be accommodated in the housing 8 advantageously compactly with the center axis of the coil in a coaxial (or alternatively parallel) orientation with respect to the longitudinal axis 80. The holder 110 is a cup-shaped device, for example a water glass, into which the pen-shaped stimulation device 1 is simply inserted. This has the advantage that the holder 110 can be easily cleaned. The plate-like or planar base 115 on which the holder 110 is placed houses the charging coil or inductor 112 on the holder side. If the stimulation device 1 is placed in the holder 110, an inductive coupling between the stimulation device 1 and an electronic power device (not shown in detail) can take place via the (preferably paired) coils above. Accordingly, the battery 76 of the simulation device 1 can also be supplied and charged with energy in wired fashion or wirelessly with this holder 110.

[0260] In addition to the explained embodiments, the invention allows further design principles.

[0261] Although the stimulation head 4 is shown with a smooth wall 41, it may also have protrusions, nubs or also indentations.

[0262] The features of the different aspects and embodiments can be combined arbitrarily with each other as long as this is technically possible. For example, the moving coil assembly 60 of FIG. 6 can be used with the third embodiment.

[0263] It will be appreciated that the sensor device 78 and the control device 7 can be formed as separate circuits or as one common circuit. If they are configured as a common circuit, they may, for example, be located on a common circuit board. In addition, the sensor device 78 and the control device 7 may be parts of a software program which are run in a computing unit.

[0264] Furthermore, the described heating unit, the proximity sensor and also the control patterns with all their associated features can also be provided in a stimulation device without the described linear drive device with an electromagnetic linear actuator which has at least one nonmoving permanent magnet and at least one conductor movably arranged in the magnetic field of the permanent magnet, the movably arranged conductor being movable in accordance with the actuation of the control device for generating vibrations.

[0265] For example, the described heating unit, the proximity sensor and also the control patterns with all their associated features can also be used in a stimulation device according to the invention which has a moving permanent magnet and a fixed coil.

[0266] Thus, according to an alternative of the invention, the drive device may have a (very easy to move, for example less than 10 grams) permanent magnet, and a fixedly installed coil of the solenoid type, with other further developments of the invention described above possibly being combined with this drive device.

[0267] Also, the described heating unit, proximity sensor and also the control patterns can be intended as a further development of the prior art.

[0268] In addition, the sensor device 783 can have signal preprocessing or signal conditioning. For example, threshold values or at least one measuring range may be provided in the sensor device 783, or the raw signals of the sensor device 783 may also be processed in the control device 7.

[0269] Also, the openings 68c of FIG. 6 e) are shown in a kidney shape, these openings 68c being adapted to the shape of the extensions 63a of the coil carrier 63. Thus, the coil carrier 63 can be provided preferably circularly in cross-section, the extensions 63a then being able to be shaped in accordance with a circular portion, which in turn results in the kidney shape of the openings 68c. For example, the coil carrier 63 can be manufactured from a tube during production, with the extensions 63a being formed by removing portions of the tube. However, the shape of the openings 68c and the extensions 63a is not limited to these specific shapes. For example, the openings 68c may be circular, and the extensions 63a may be pin-shaped.

[0270] Furthermore, the measures to increase the mechanical robustness of the moving coil assembly 60 of FIG. 6 a) to 6 e) can also be used with other stimulation heads 4 or other shapes, layered arrangements or other forms of a head element 45. This is shown, for example, in FIGS. 3, 4 and 5. In other words, the various measures to increase mechanical robustness (for example a second suspension) can in principle also be used with other moving coil assemblies 60, for example the feature of a further suspension 65a, 65b can also be combined with other stimulation heads 4 (especially that of FIG. 4).

[0271] Furthermore, the moving coil 62 can be provided overhanging or underhanging or otherwise dimensioned as long as it can vibrate in the magnetic field of the moving coil assembly 60 when excited. The moving coil 62 can also be single wound, double wound or have different winding heights as long as it can vibrate in the magnetic field of the moving coil assembly 60 when excited.

[0272] Furthermore, in accordance with a development of the described teaching, the moving coil assembly 60 with the stimulation head 4 can be dimensioned in such a way that the resonance frequency of the arrangement is at approximately 80 Hz (+/5 Hz), with the 6 dB limit of the corresponding frequency response of the arrangement in the range between 60 Hz to 100 Hz preferably not being undershot, thus providing an optimum working range within this range. According to experiments by the inventors, this frequency range has proven to be particularly stimulating for the clitoris.

[0273] For example, the total mass of the at least one suspension 65, 65a, 65b (centering spider), the moving coil 62, the stimulation head 4, as well as the magnetic flux density of the moving coil assembly 60 and the spring force of the suspension(s) may be dimensioned such that the resonant frequency of the assembly is about 80 Hz (+/5 Hz).

[0274] The measuring range can also have a different shape than the one shown in the drawings. For example, it can be ring-shaped or conical.

[0275] FIG. 19 to 25 show further embodiments of an arrangement for a stimulation device 1 or arrangements for the drive unit or device 6. In each case, coil elements of an electromagnetic linear drive are arranged so that they can be moved or displaced in a stationary permanent 10 magnetic field. Like reference signs as compared to the previous drawings are used for like features.

[0276] In the embodiments in FIG. 19 to 25, the suspension or holder 65, which acts as a positioning or centering device for the carrier 63 with the (voice) coil 62 and is optionally formed with a membrane, is shown in a neutral starting state in which no deflection has occurred. In contrast to this, FIGS. 26 and 27 show an embodiment in which the carrier 63 with the moving coil 62 moves from the neutral starting or zero position (see FIG. 19 to 25) downwards into the stationary permanent magnetic field. Together with the carrier 63, the displaceable head element 45 is displaced downwards. During operation the carrier 63 with the moving coil 2 and the displaceable head element 45 then vibrate around the neutral rest position, starting from the deflected starting position shown in FIGS. 26 and 27. In other embodiments, in particular the examples shown in FIG. 19 to 25, the carrier 63 is vibrated around this neutral starting position starting from the neutral rest position shown in FIG. 19 to 25.

[0277] The embodiments in FIGS. 26 and 27 make it possible, in particular, to apply an electrical current of non-changing polarity to the moving coil 62 for operation. A current of alternating polarity is, however, provided for in other embodiments, for example in one or more of the embodiments shown in FIG. 19 to 25. Embodiments other than those shown in FIGS. 26 and 27 can also be operated around a deflected position different from the neutral rest or starting position.

[0278] In the embodiments in FIG. 19 to 22 the moving coil 62 has an upper moving coil 62a and a lower moving coil 62b with separate coil windings. In the examples in FIGS. 19 and 20, the upper and lower moving coil 62a, 62b are each arranged opposite pole plates 68a, 68b, with the permanent magnets 66 arranged outside (FIG. 19) or inside (FIG. 20) relative to the moving coil 62. The internal design supports the formation of an optimized magnetic induction.

[0279] Also, in the examples in FIGS. 21 and 22, the permanent magnets 66 are arranged outside relative to the moving coil 62. The arrangement of the permanent magnets 66 shown there, which, as compared to the embodiment in FIG. 19, are provided instead of the upper pole cap 68a or the lower pole cap 68b, supports a flat design.

[0280] The embodiments in FIG. 23 to 25 use a one-piece coil 62 as compared to the embodiments in FIG. 19 to 22, however, the permanent magnets 66 may also be arranged internally and externally relative to the coil 62, as shown according to FIGS. 23 and 24. In the embodiment in FIG. 25, the permanent magnets 66 are arranged below the moving coil 62.

[0281] In the example in FIG. 19, upper and lower pole caps 9a, 9b are provided, which are arranged above and below the permanent magnets 66. In the embodiment in FIG. 20, the upper and lower pole caps 68a, 68b are arranged above and below a central pole cap 68c and in contact therewith.

[0282] In the embodiments in FIGS. 26 and 27, the permanent magnets 66 are arranged between the upper or front pole plate 68a and the lower or rear pole plate 68b and in contact therewith. According to FIG. 26 a spring 150 is provided, which provides a spring pretension against the shown deflected position of the carrier 63 with the moving coil 62. FIG. 27 shows an alternative embodiment in which the spring 150 is omitted. A pretension can be provided here by means of the suspension/holder 65.

[0283] The features disclosed in the above description, the claims and drawing may be relevant either individually or in any combination for the realization of the various embodiments.
