DETAILED DESCRIPTION

[0257] In the section below, the same or identical features, which have already been described in more detail in terms of the preceding embodiment with reference to a preceding aspect are not explained again in order to avoid repetitions. The same reference numerals refer, in general, to the same features, or those with a corresponding function.

[0258] With reference to FIG. 7 a), a side view of a stimulation device 1 according to the invention of a first embodiment and, with reference to FIG. 7 b), a view of the stimulation device 1 according to the invention of FIG. 7 a) from behind is explained in more detail.

[0259] FIGS. 7 a) and 7 b) show an elongated and rod-shaped stimulation device 1 having a housing 8 (for example made of ABS plastic), and a front end 90, a back end 91, wherein the stimulation device 1 is formed to be circular in terms of its cross section or in terms of the external contour on its cross-section plane. In the back end, an on/off switch 74 is provided, which optionally has a lighting element for displaying the switching state. An optional display 72 can relay the current setting of the modulation pattern or the strength of the stimulating pressure field. A central section 88 is optionally coated with silicone, while the gripping surface 89 (and a further gripping surface 89 on the side facing away that is not depicted in more detail) in the form of an elongated oval surface (for example as a Lame oval) determines the preferred placement position for the finger and ensures a good hold for the finger. These gripping surfaces 89 can be shown by colour, for example, or an additional rubber coating can be applied on the surface of the central section 88.

[0260] A cup-shaped cap 85 that is complementary to the front end 90 or that fits in terms of shape is formed in such a way thatmuch like a cap of a penit can be placed on the front end 90. The cap 85 covers (and protects) the front head or the wall 41 and the opening 42 of the stimulation device 1 in the placed-on state and reaches up to the passage or the intersection of the wall 41 on the front end 90 relative to the central section 88 in the longitudinal direction.

[0261] Preferably, the outer diameter of the cap 85 in the transverse direction is the same as the external diameter of the housing 8 in the transverse direction.

[0262] The opening 42 of the stimulation device 1 is arranged in the front end 90, wherein the longitudinal axis 80 penetrates the opening 42. The directions to the front and to the back are correspondingly shown by the arrows in the Figure. The front end 90 is the active end which is used for the stimulation by means of the pressure field.

[0263] The opening 42 is formed to be chamfered or at an angle in relation to the longitudinal axis 80, which is why the opening plane 83 (which is defined by the outer edges of the opening) is intersected by the longitudinal axis 80 at an angle . This angle is preferably 60 degrees (5 degrees). The axis labelled with the reference numeral 81 depicts the alignment axis 81 of the hollow space 10 of the stimulation device 1 according to the invention. Thus, the hollow space 10 and the opening 42 are formed in a current-technical manner in the region of the opening 42 in such a way that the pressure field has preferred directions in term of current (of the forward and backward movement of the medium) at the opening 42 of the housing 8 along the alignment axis 81 in the non-placed state of the stimulation device 1.

[0264] The on/off switch 74 can preferably be formed to be embedded in the housing 8 so that it does not protrude from the housing 8.

[0265] The longitudinal axis 80 is an imaginary line between the front end 90 and the back end 91, which presently also depicts the axis of symmetry for the base shape of the housing 8 in FIGS. 7a and 7b. In these symmetry considerations, operating elements 74, displays 72 or gripping surfaces 89 are not taken into consideration, which represent only marginal adjustments of the base shape of the housing 8.

[0266] The alignment axis 81 preferably intersects the longitudinal axis 80 at an angle of 30 degrees, while the opening plane 83 is arranged at a right angle to the alignment axis 81.

[0267] Thus, the stimulation device 1 according to the invention has a compact, narrowly elongated construction. This leads to weight savings and an ergonomic operability of the device 1. Preferably, the stimulation device 1 of FIGS. 7 a) and 7 b) is implemented to be waterproof (IP67). Therefore and because of the simple external shape of the stimulation device 1, it is easy to clean.

[0268] With reference to FIG. 8 a), a side view of a stimulation device according to the invention of a second embodiment and, with reference to FIG. 8 b), a view of the stimulation device according to the invention of FIG. 8 a) from behind is explained in more detail.

[0269] The second embodiment has a regular hexagonal housing 8 which has a flat back end 91. Thus, this housing 8 can be advantageously picked up or put down, as well without it rolling away. The housing shape thus serves as roll prevention. The opening plane of the opening 42 in the front end 90 of the housing 8 is arranged to be at a right angle (cf. angle ) to the longitudinal axis 80. In this embodiment, the alignment axis 81 coincides with the longitudinal axis 80. The on/off switch 74 and the display 72 are arranged to be adjacent to the front end 90. The cap 85 is formed analogously, as in the first embodiment, and fits correspondingly to the housing shape of the housing 8 of the second embodiment.

[0270] With reference to FIG. 9 a), a side view of a stimulation device according to the invention of a third embodiment and, with reference to FIG. 9 b), a view of the stimulation device according to the invention of FIG. 9 a) from behind is explained in more detail.

[0271] The housing 8 of this embodiment is formed to be somewhat centrally waisted, and tapers correspondingly towards the centre. The two swellings or bulgeswhen seen in the longitudinal direction of the housing 8to the left and right of the central tapering preferably both have the same maximum radius in the transverse direction. The housing 8 thus has a shape similar to that of a dog bone.

[0272] The cross-sectional shape of the housing 8 is approximately oval, and is preferably retained with the same width/height ratio across the entire length of the housing 8. This leads to the housing 8 lying comfortably in the hand, and does not easily roll away, if the to stimulation device 1 is put down.

[0273] At the same time, the central section 88 forms the gripping surface 89 over its entire surface, wherein this preferably provides a rubbery coating. Furthermore, the central section 88 is formed via further parts of the housing 8 in the longitudinal direction. In synergy with the waisted shape of the housing 8, this leads to an ergonomic handling of the housing 8, since the housing 8 comes to rest in the narrow region in the middle in or on the hand, when the housing 8 is guided in the manner of a writing device. In addition, thumb and index finger rest on the front swelling of the housing 8 in this gripping position, which is more ergonomic.

[0274] In addition, the stimulation device 1 has the swelling or pommel-like cross-section enlargement on the back end 91. This advantageously leads to the stimulation device 1 having a kind of pommel or head on the back end 91, at which point the stimulation device 1 can be held comfortably in a closed hand (for example in a first hold), which also represents an ergonomic holding.

[0275] Alternatively, the swelling of the housing 8 can have a larger maximum radius in the transverse direction on the back end 91, like the front swelling.

[0276] The opening 42 of the hollow space of the stimulation device 1 has a slightly concave opening plane, since the front end of the opening 42 runs slightly wavy or wave-shaped in the front end 90 of the housing 8. In this case, the emerging opening plane is also slightly concavely curved or arched. Such a curvature of the opening plane leads to the opening 42 being able to be placed more pleasantly over the area of skin that is also (slightly) curved or not even, said area of skin surrounding the female clitoral glans. Thus, the opening plane 83 is adjusted in terms of its shape to the anatomy of the clitoris in such a way that the opening 42 can be placed in a form-fit manner or fitting to the area of the skin which surrounds the clitoral glans without significant pressing pressure. The angle of intersection of the opening plane 83 with the longitudinal axis 80 is determined in terms of the intersection point with the longitudinal axis 80, and is the smallest possible angle. An angle region of about 65 to 75 degrees was experimentally determined as the optimal angle for the use of such a curved opening plane 83 for using on the clitoris 12.

[0277] The cap 85 is formed to be analogous to the first embodiment, and fits correspondingly to the housing shape of the housing 8 of the third embodiment.

[0278] The angle of intersection y between the alignment axis 80 and the longitudinal axis 81 is a pointed angle. Preferably, this is about 3 to 12 degrees, which, after experiments, has generally been proven to be a more pleasant angle region for handling for the user.

[0279] With reference to FIG. 10 a), a side view of a stimulation device according to the invention of a fourth embodiment is explained in more detail and, with reference to FIG. 10 b), a view of the stimulation device according to the invention of FIG. 10 a) from behind is explained in more detail.

[0280] FIG. 10a shows a housing that is triangular in terms of its cross-section, which is formed to be elongated. Preferably, the external shape is designed to be of equal thickness in the cross-section directional to save material and weight. Thus, on the one hand, a very light and compact housing can be realised, while on the other hand, a triangular housing of equal thickness fits well to the anatomy when holding the housing 8 with thumb and index finger in the manner of a writing device, and is therefore ergonomic.

[0281] The on/off switch, in turn, is realised to be embedded in the back end 91 of the housing 8 so that the device 1 can be placed upright on a table, for example, by means the flat back end.

[0282] The gripping surfaces 89 (one of which is not depicted in more detail, since this is arranged to be covered on the side of the triangle that is of equal thickness that is facing away) are realised to be elongated ovals, and arranged in such a way that they constitute the support surface of the finger on the housing 8 when the housing 8 is guided in the manner of a writing device. The two gripping surfaces are thus arranged to be asymmetrical. The gripping surface 89 depicted in FIG. 10a is provided for the thumb of a left-handed person. The gripping surface not depicted in more detail would be arranged to correspond to the (imaginary) position of an index finger on the other side of the triangle in an elongated oval shape rather than in the direction of the longitudinal axis 80 of the housing 8. Thus, the gripping surfaces can be adjusted in terms of their flat arrangement fundamentally to the anatomy of the hand and the finger of the users (particularly preferably after determining whether the present user is right-handed or left-handed).

[0283] In additional, the gripping surfaces 89 can also be formed as trough-shaped indents in the central section 89. Alternatively, the gripping surfaces 89 can have corresponding rubber coatings in order to improve the grip of the device.

[0284] The cap 85 according to the invention is formed to be analogous to the first embodiment, and fits correspondingly to the housing shape of the housing 8 of the third embodiment and continues the housing shape in the longitudinal direction 80.

[0285] With reference to FIG. 11 a), a side view of a stimulation device according to the invention of a fifth embodiment and, with reference to FIG. 11 b), a view of the stimulation device according to the invention of FIG. 11 a) from behind is explained in more detail.

[0286] In the fifth embodiment, the external shape of the cross-section changes at the passage between the central section 88 to a back section 86. The central section 88 is preferably implemented to be triangular in terms of it cross-section having rounded corners or edges (in particularly of equal thickness; alternatively, the central section 88 of this embodiment can also be formed to be round or oval). The back section 86 is preferably formed to be cuboid or quadratic in terms of cross-section (alternatively, it can be formed to be rectangular or even spherical; the latter leads to forming a ball or button-shaped holding pommel on the back end 91 of the stimulation device 1). Here, these parts are preferably arranged in the back section 86 of the housing 8, said parts being heavy or having a high weight, for example the battery. Thus, the centre of mass MA of the housing 8 of the stimulation device 1 is further placed towards the back in the direction of the back end 91, which leads to better handling.

[0287] The ratio of length A to width B (which is the same as height C) of the housing is preferably 3.5 (three point five), in particular 3.9 (three point nine). Because of this elongated embodiment, the housing 8 can be handled more easily and more ergonomically.

[0288] The display 72 is implemented on the back end 91 of the housing 8 in the form of an LED display surrounding the on/off switch. Thus, the user intuitively associates the display of the switching state with the corresponding on/off switch, and vice versa.

[0289] Thus, the fifth embodiment is preferably characterised in that the external contour of the housing 8 changes from the central section 88 to the back section 86. In other words, the fifth embodiment is preferably characterised in that the central section 88 has a different external contour to that of the back section 86.

[0290] In comparison to the caps 85 of the first to the fourth embodiment, the cap 85 of the fifth embodiment is formed to be longer. When the cap 85 of the fifth embodiment is placed on the housing 8, then not only the front end 90 is surrounded by the wall 41, but also the central section 88. Thus, the edge 851 of the cap 85 abuts on the edge 861 of the back section 86, when the cap 85 is placed on the housing 8. If this cap 85 is placed on completely, then the stimulation device 1 gives off a uniform, elongated cuboid impression with which it is not immediately recognisable, what purpose the device 1 contained has. Therefore, in the present discrete, light and compact design of the stimulation device 1, the stimulation device 1 can be taken in the handbag in a discrete and hygienic manner, for example.

[0291] The angle between the plane of the opening 42 of the hollow space and the longitudinal axis 80 is about 80 degrees, preferably about 80 to 90 degrees, in particular about 90 degrees.

[0292] In the fifth embodiment, the alignment axis 81 can further preferably coincide with the longitudinal axis, i.e. these are preferably arranged coaxially relative to each other.

[0293] Below, with reference to FIG. 12 a), a side view of a stimulation device according to the invention of a sixth embodiment, with reference to FIG. 12 b), a view of a stimulation device according to the invention of the sixth embodiment from the front, and, with reference to FIG. 12 c), a view of a stimulation device according to the invention of the sixth embodiment from behind, and, with reference to FIG. 13, a perspective view of a 3D wireframe model of the sixth embodiment of the stimulation device according to the invention are explained in more detail.

[0294] In terms of its basic principle, this sixth embodiment is similar to the fifth embodiment, to which reference is made.

[0295] An elongated housing 8, which is presently depicted standing upright in FIG. 12a, extends along a longitudinal axis 80 and has the opening 42 of a second chamber 4 on the front end 90. Furthermore, the housing on the front end 90 has a (flat) resting region 43 which comes into contact with the skin.

[0296] Latching closures 862 are provided for fixing the cuboid and hollow cap 85, said latching closures 862 latching when the cap 85 is pushed over the front end 90 and over the central section 88 of the housing 8 up to the opposite contact of the stop edges 861 and 851.

[0297] In FIG. 12a, the cap 85 is depicted next to the housing 8 only for simplification.

[0298] The centre of mass MA of the stimulation device 1 is in the back section 86, whereby this can be handled better. Furthermore, the centre of mass is preferably set up in such a way that is in on the longitudinal axis 80. This also improves the handling of the stimulation device 1, since the lateral tipping moments are reduced or avoided. In addition, the previously explained position of the centre of mass is calibrated or set up by means of additional (small) weight elements inside the housing 8.

[0299] The longitudinal axis 80 represents an axis of symmetry or the cap 85, for the back section 86 and for the central section 88.

[0300] For example, the housing is about 4 cm wide (reference numeral C), and about 12 cm long (reference numeral A). Alternatively, the housing is about 3 cm wide, for example, (reference numeral C) and about 12.5 cm long (reference numeral A). Thus, it has been shown in the development of the stimulation device that the resulting internal volume of the housing with the previous alternative dimensions of the housing 8 has precisely sufficient space in order to receive the components (motor, battery, control device etc.) of the stimulation device 1.

[0301] With reference to FIG. 12 b), which shows a view of the stimulation device 1 (or on the left side of FIG. 12 b), the housing 8 and on the right side of FIG. 12b, the cap 85) from in front, the external contour of the central section 88 and the head of the stimulation device 1 having the opening 42 can be seen. These are implemented to be approximately of equal thickness, which leads to the corresponding advantages that have been described previously.

[0302] The opening 51 of the connection element 5 into the second chamber 4 is formed to be oval. The second chamber is arranged along the longitudinal axis 80 in such a way that the alignment axis 81 of the hollow space according to the invention is in parallel to (preferably coaxially with) the longitudinal axis 80 of the housing 8. The second chamber 4 is provided having its corresponding wall 41 to be able to be placed or exchanged. The opening 42 of the second chamber 4 is implemented to be oval. The second chamber 4 widens in terms of current of a diffuser from the opening 51 in the direction of the opening 42, in order to facilitate the formation of the positive pressure of the pressure field according to the invention.

[0303] Furthermore, in FIG. 12 b), on the right-hand side, a top view of the cap 85 according to the invention is depicted. This has a quadratic base cross-section, which is implemented to be slightly bulged. In the middle on the end surface of the cap, space is provided for a logo 852.

[0304] FIG. 12 c) shows a view from behind of the stimulation device 1 (or, on the left-hand side, a back view of the housing 8 and, on the right-hand side, a back view into the cap 85). On the back side of the housing 8, in the middle within a repositioned or embedded end surface 863, an on/off switch 74 having a corresponding light ring 72 is provided as a display. Furthermore, a bushing 75 for the connection of a current supply is provided. This bushing can be closed with a correspondingly sealing stop.

[0305] The perspective view of the sixth embodiment of FIG. 13 represents, in particular, the slightly slanted, widely implemented front surface of the wall 41 of the pressure field generation device 2. With the preferably widened support surface 43 or the placing region 43 of the wall 41 for placing over the clitoris, the pressure is distributed across the surface, which is more pleasant during use. Thus, the usual relatively sharp and uncomfortable edges of openings of stimulation devices of the prior art are replaced by the resting surface 43 or the placing region 43 according to the invention, which has a surface which is arranged (approximately) in parallel to the opening plane 83 and completely surrounds the opening 42.

[0306] With reference to FIGS. 14 to 18, a seventh embodiment of the present invention is explained in more detail. FIG. 14 shows a perspective view of a stimulation device according to the invention of a seventh embodiment having a closed cap. FIG. 15 shows a perspective view of a stimulation device 1 according to the invention of the seventh embodiment having an opened cap. FIG. 16 shows a side view of a (lying) stimulation device according to the invention of the seventh embodiment having an opened cap. FIG. 17 shows a side view of a (standing) stimulation device according to the invention of a seventh embodiment without a cap. FIG. 18 shows a view of the stimulation device according to the invention of the seventh embodiment from the front.

[0307] The seventh embodiment is provided to be very similar to the sixth embodiment. Therefore, only the differences relative to one another are explained in more detail below.

[0308] In the back end 19, the bushing 75 for the current supply having a latch-like plug-bushing closure 751 (preferably made of silicone or rubber) is set up in such a way that the closure 751 can seal or caulk the bushing in a waterproof manner (IP 67).

[0309] The display 72 is implemented in the form of a transparent viewing panel and an LED behind it. The on/off switch is preferably simultaneously the operating element, by means of which the modulation of the pressure field can be set. Thus, the stimulation device is switched on or off by means of a long press in each case, whereas a short press changes the modulation.

[0310] The central section 88 is implemented to be approximately of equal thickness and coated with silicone. Thus, the whole central section 88 constitutes a coherent gripping surface 89. The wall 41 is continued in a seamless or transition-free manner by means of the central section 88, wherein the head and the central section 88 of the housing 8 has the same external contour in cross-section.

[0311] With reference to FIGS. 16 and 17, it can be seen that the back section 86 tapers forwards in a step-like manner, in particular, so that the cap 85 can be placed on the housing 8 in a form-fit manner. The head of the stimulation device is implemented to be slanted or slightly curved, wherein the opening plane 83 of the opening 42 intersects the longitudinal axis 80 at an angle . The angle of this embodiment is about 60 degrees (60 degrees10 degrees). Preferably, the angle of this embodiment ranges from about 40 to 70 degrees, in particular ranges from about 55 to 65 degrees.

[0312] The longitudinal axis is presently an axis of symmetry for the cap 85 and the basic shape of the back section 86 of the housing.

[0313] The centre of mass MA is preferably in the back section 86 of the housing 8.

[0314] FIG. 18 shows a view of the housing 8 of the seventh embodiment from the front. Thus, the opening 51 inside the hollow space is formed to be circular in the cross-sectional direction. Furthermore, a widened resting surface 43, which intersects the opening plane 83 at a slight angle, is provided. The opening 42 is, in turn, provided to be oval.

[0315] With reference to FIG. 19, a side view of a central section 88 or a gripping part having a gripping surface 89 according to the invention of the seventh embodiment is explained in more detail and, with reference to FIG. 20, a sectional view in the cross-sectional direction of the housing of the central section 88 according to the invention or a gripping part having a gripping surface 89 of the seventh embodiment is explained in more detail. Thus, the central section 88 is preferably implemented as one piece as a single component of the stimulation device 1.

[0316] The central section 88 has a length G which is at least 30%, preferably at least 40% of the total length A of the housing 8 (which is measured without the cap 85).

[0317] The external contour of equal thickness which is shown (cf. FIG. 20, reference numerals 882 and 881) of the central section 88 does not have any sharp outer edges or hard corners in the longitudinal direction in comparison to Reuleaux triangles, but is implemented to be rounded throughout (c. reference numeral 881). The total diameter of the central section 88 is r-min at each point plus r-max.

[0318] The longitudinal axis 80 of the housing 8 constitutes a central axis for the central section 88.

[0319] With reference to FIG. 21, a schematic cross-section is explained in more detail by a principal pressure field generation device of one aspect of the present invention.

[0320] A hollow space 10 forms an at least extensively closed unit (i.e. an at least closed volume) after placing the stimulation device over the related body part 11 to be stimulated, preferably the clitoris 12. There is a medium, preferably air, in the hollow space.

[0321] This hollow space can be functionally divided into a first chamber 3, a second chamber 4 and a connection element 5.

[0322] Here, the term first chamber 3 functionally refers to the part of the hollow space at which the drive unit 6 can act on the hollow space, for example by means of a regular volume change. Thus, the volume of the first chamber 3 is alternately enlarged and reduced.

[0323] The term second chamber 4 further functionally refers to the part of the hollow space which has the opening 42 for placing over the erogenous zone, and in which the pressure field according to the invention can act on the erogenous zones or on the clitoris (or clitoral glans) 12. The chambers 3 and 4 according to the invention should thus not be understood in such a way that they constitute spaces or departments of the hollow space which are each completely separated in terms of structure. The two chambers 3 and 4 are connected via the connection element 5, for example in the form of a straight (and preferably rigid) channel (in terms of current). Preferably, the connection element 5 can also represent only a slight tapering or narrowing in the form of an individual outlet opening or a wide channel between the two chambers 3 and 4 having two openings 33 and 51. The two openings preferably have a common central axis.

[0324] The first chamber 8 has a flexible wall 31 which can be supplied and displaced by means of the drive unit 6 by forces. The flexible wall 31 is fixed in a bracket 32. This bracket 32 preferably consists of a rigid plastic.

[0325] Because of the regular volume change by means of the drive unit 6, a current system is formed in the hollow space 10.

[0326] In detail, the pressure field generation device 2 has an opening 42 or placing over the clitoris 12 and a flexible wall 31, wherein the pressure field generation device 2 is set up in such a way that, when the opening 42 is placed over the clitoris 12, an at least extensively closed current system is formed in the pressure field generation device 2, and the drive unit 6 acts on the flexible wall 31 with forces during control in such a way that this is displaced away from the clitoris 12 in a first direction and towards the clitoris 12 in a second direction, in a temporally alternating manner, whereby media currents in the current system of the hollow space 10 which are aimed towards the clitoris 12 and away from the clitoris 12 in a temporally alternating manner, are generated and a pressure field consisting of a pattern of negative and positive pressures which are modulated in relation to normal pressure is generated; and wherein the at least extensively closed current system extensively or completely avoids a removal of bodily fluid from the pressure field generation device 2, such that the pressure field generated in the current system of the pressure field generation device 2 stimulates the clitoris 12 for sexual arousal.

[0327] By means of the double arrows, the movement directions of small exemplary volume shares of the medium in the current system according to the invention are depicted in FIG. 21, i.e. the currents according to the invention. Thus, these move forwards and backwards to correspond to the displacement of the flexible wall in parallel to the axis of the alignment 81 of the hollow space 10. Considered as a whole, a kind of media column or air column is thus cyclically moved forwards and backwards in the hollow space, wherein the pressure field according to the invention is formed to be adjacent to or on the clitoris (or clitoral glans). Furthermore, mechanic vibrations starting from the flexible wall 31 (induced by the acting forces and also introduced by the drive unit 6) are transferred via the bracket 32 and the wall 41 of the second chamber 4 in the direction of the body part 11 to be stimulated, which is seen as disturbing, in certain circumstances.

[0328] With reference to FIG. 22, a schematic cross-section of a pressure field generation device of a further aspect of the present invention is explained which addresses the theme of the vibrations explained above.

[0329] The current system of this aspect according to the invention is formed to have an angled shape. Thus, the flexible wall 31 is displaced at a right angle (or alternatively at a different angle of at least 45 degrees) relative to the alignment axis 81 of the hollow space 10. The corresponding vibrations thus no longer propagate in the direction of the body part to be stimulated, for example in the direction of the clitoris, but at an angle to it, as depicted in FIG. 22. When applying this aspect to the first to seventh embodiment, the vibration would thus have a (core) direction which is aligned in the transverse direction of the longitudinal housing 8. As a result, the disturbing vibrations in the longitudinal direction 80 of the stimulation device 1 are reduced in the direction of the front end 90.

[0330] FIGS. 23 to 25 present the principle of the pressure field generation device 2 in detail.

[0331] FIG. 23 shows a principle pressure field generation device 2 in a first state, wherein the second chamber 4 is placed on or over the region of skin or body part 11 to be stimulated. Preferably, the second chamber 4 is placed over the erogenous zone which has the female clitoral glans.

[0332] The first state of the pressure field generation device 2 is characterised by a neutral displacement of the first chamber 3, i.e. it does not exert an external force, for example from the drive unit, on the first chamber 3. Here, the volume V1 of the first chamber is the standard volume of this chamber 3.

[0333] The body part 11 to be stimulated is a region of skin of the body, wherein here, for example, a particularly sensitive erogenous zone, the clitoris 12, is depicted. Thus, the application of the present invention, however, is not fundamentally limited to the female clitoris 12, but the stimulation device 1 can be applied to all body parts or erogenous zones (for example the inside of the upper thigh, groin, neck, nipples, etc.), which can be stimulated by means of media or air pressure massage and/or negative pressure.

[0334] The second chamber 4 forms a chamber that is extensively or completely closed to the outside of the pressure field generation device 2 by placement on the body part 11 to be stimulated or because of the placement over the clitoris to be stimulated, said chamber being connected to the second chamber via only the connection element 5, wherein the edges of the chamber 4 ideally close in a sealing manner by means of the surface of the body part 11. In this way, a closed hollow space having two communicating functional units, chambers 3 and 4, emerges, wherein, when changing the volume of one of the chambers 3 or 4, a corresponding pressure equalisation between chamber 3 and 4 takes place via the connection element 5.

[0335] A wall 31 of the first chamber 3 is fixed by means of a bracket. The bracket 32 is, in turn, fixed on the housing 8. Furthermore, the wall 41 of the second chamber is mounted on the bracket 32. Two openings in the wall 41 of the second chamber 4 and the bracket 32 which are aligned relative to each other (preferably in the longitudinal direction) together form the connection element 5, which connects the first chamber 3 and the second chamber 4 by means of a channel. This channel runs straight between the first chamber 3 and the second chamber 4, wherein the diameter of the channel broadens or narrows in the direction of the second chamber 4. Here, the wall 31, the bracket 32 and the wall 41 are preferably adhered to one another to be media- or air-proof. Alternatively, these can also be press-fitted to one another (for example by means of sealing regions between the housing 8 and the respective part) or screwed together. Furthermore, the bracket 32 can be adhered or screwed to the housing 8, for example.

[0336] The wall 31 of the first chamber 3 consists preferably of a flexible media- or air-impermeable material, for example rubber or silicone. The bracket preferably consists of a rigid plastic, which is also media- or air-impermeable. The wall 41 of the second chamber is preferably produced from a flexible, skin friendly material, for example from silicone or rubber.

[0337] FIG. 24 shows the pressure field generation device 2 of FIG. 4 in a second state, wherein, in turn, the second chamber 4 is placed on the body part 11 to be stimulated. The second state is characterised in that a force A acting on the first chamber 3 causes an to expansion of the chamber 3. In detail, in this embodiment, the force A pulls the wall 31 of the first chamber 3 in a direction which is aimed away from the second chamber 4.

[0338] As a result, the volume V2 of the chamber 3 enlarges, i.e. V2>V1. In order to equalise the arising pressure difference between the chambers 3 and 4, the medium or the air now flows from the second chamber 4 into the first chamber 3.

[0339] Assuming that, in the first state, the pressure present in chambers 3 and 4 corresponds to the current prevailing external reference pressure (for example air pressure), the present total pressure in the second state is now lower than the external reference pressure. This negative pressure is constructed in such a way that it is preferably lower than the usual systolic blood pressure in the blood vessels of the body part 11. Thus, the blood flow in this region is increased and more blood flows to the clitoris 12 in the second state.

[0340] FIG. 25 shows the pressure field generation device 2 in a third state, wherein, in turn, the second chamber 4 is placed on the body part 11 to be stimulated. The third state is characterised in that a force B acting on the first chamber 3 causes a volume reduction or compression of the chamber 3. In detail, the force B is opposed in terms of its direction to the direction of force A and deforms the wall 31 of the first chamber in such a way that the resulting volume V3 of the chamber is smaller than volume V1. The compression of the chamber 3 causes a positive pressure in the chamber 3 which is equalised by a media or air current through the connection element 5 in the direction of the second chamber 4.

[0341] This media current is now preferably aimed at the body part 11 to be stimulated, in particular at the glans of the clitoris 12, by means of the alignment of the opening 51 and/or the connection element 5. The indirect (pressure) stimulation according to the invention thus takes place by means of the medium flowing in the direction of the erogenous zones. Here, the size (or the cross-sectional surface area) of the opening 51 is preferably sized in such a way that this is small enough in comparison to the volume displaced in the first chamber 3 in order to sufficiently accelerate the medium for a perceptible massage effect. Often, in particular with a clitoral glans, a slight cross-sectional reduction or narrow point in the hollow space is sufficient so that the pressure field according to the invention can develop a targeted stimulation effect.

[0342] Furthermore, the type of current can be advantageously influenced not only by means of the size and the alignment of the opening 51, but also by means of the inner configuration of the connection element. For example, helical grooves in the connection element 5 cause a swirl of the current according to the invention, wherein the current profile of the current develops a softer or more turbulent effect on the body part to be stimulated. Alternatively, the pressure field emerging in the second chamber 4 can be adjusted to correspond to the use by means of several openings 51. As a further alternative, a nozzle can be provided as the connection element, which leads to the pressure field being constructed in the medium preferably adjacent to the clitoris.

[0343] In the arrangement shown in FIGS. 23 to 25, it is advantageous that it is hygienically unproblematic (for example because of the avoidance of dead spaces) and simple in terms of construction. For example, no valves or further openings in or on the first chamber 3 are required. It is noted that the basic principles of the pressure field generation of the invention are then also realised when the starting point of the compression and expansion activity of the drive unit 6 is at the maximum volume V2 or the minimum volume V3. Thus, often a pressure equalisation, for example via a gap between the skin and the opening 42, takes place, in which the average pressure in the hollow space will level to a central pressure. In addition, the device 1 is often already switched on before the placement over the erogenous zone. Thus, the pressure field according to the invention is generated independent of the prevailing starting conditions in terms of the displacement of the flexible wall 31 of the first chamber 3.

[0344] FIGS. 26a to 26e disclose further aspects in terms of the formation, in particular in terms of the (inner) shaping of the connection element 5.

[0345] The shaping of the connection element 5 influences the current-mechanical properties in the pressure field generation device 2. With the through current of channels or hollow spaces, current sounds, in particular with air as the medium, occur which are independent of the current speed, of the cross-section of the channel and the degree of turbulence. Turbulences are, in turn, caused by sharp edges.

[0346] FIG. 26 a) shows the connection element 5 in the shape of a straight channel, wherein the opening 33 and the opening 51 each have sharp edges on the edges of this. This leads to turbulences and disturbing current sounds.

[0347] Thus, the pressure loss coefficient of arrangement of FIG. 26 a) is capable of optimisation. The stimulation effect of the pressure field of the stimulation device 1 can be optimised according to the invention by an improved configuration in terms of current, as is presented in more detail below.

[0348] FIG. 26 b) shows the connection element 5 in the form of a straight channel, wherein the edge of the opening 33 (in the direction of the first chamber 3) has rounded corners. This reduces the pressure loss coefficient of the channel-like configuration according to the invention, which is why the degree of effectiveness of the pressure field generation device according to the invention becomes larger and this becomes quieter. In addition, the second chamber 4 has a larger internal diameter in comparison to the second chamber of FIG. 26 a), whereby the pressure field emerges closer to the opening 51, and the second chamber 4 can thus be provided to be comparatively shorter in the longitudinal direction, which saves space and weight.

[0349] FIG. 26 c) shows the connection element 5 in the shape of a straight channel having a truncated conical opening 33 in the direction of the first chamber 3. This further reduces the pressure loss coefficient in comparison to the channel-like configurations of FIG. 26 a) and b).

[0350] FIG. 26 d) shows a further improved configuration in terms of current of the connection element 5. Thus, the first chamber 3 and the second chamber 4 are separated by a marginal (for example by about c. 15% of the diameter of the first chamber) narrowing or constriction of a channel-shaped connection element 5, wherein the two openings 33 and 51 (on both sides of the channel) have a truncated conical internal shape. As a result of the medium being moved forwards and backwards in the current system according to the invention, the two openings or sides of the channel are advantageously optimised in terms of current since the two current directions are lossy.

[0351] Thus, it is possible to optimise the pressure loss coefficient in comparison to conventional stimulation devices in such a way that a smaller (or weaker powered) electric motor can be used, which saves weight and costs. In addition, the current sounds are avoided or reduced, which improves the ergonomics of the stimulation device 1.

[0352] FIG. 26 e) shows a shaping of the second chamber 4. In order to distance the clitoris (or clitoral glans) from the nozzle-like opening 51 further from the clitoris (in order to avoid an over-stimulation), it can be necessary that the length of the second chamber is enlarged in the direction of the alignment axis 81 and/or in the direction of the longitudinal axis 80. Thus, the second chamber 4 can be set up in such a way that its diameter (in the cross-sectional direction) is gradually enlarged in a multitude of (preferably two) steps in the direction of the opening 42. Correspondingly, the media flow (when the first chamber 3 is compressed) is gradually decelerated in the direction of the opening 42, while the pressure field is aimed at the erogenous zone to be stimulated in a targeted manner, since the media pressure gradually increases.

[0353] FIG. 27 shows a first chamber 3 having an opening 33 of the first chamber 3 arranged at a right angle to the direction of the displacement of the flexible wall 31, and a channel-shaped connection element 5, which has an S-shaped course. Thus, the channel running in an S-shape forms a damping element 5 according to the invention. Thus, in this aspect, because of the S-shaped course of this aspect, a direct, straight-line expansion of acoustic effects outwards from the first chamber 3 is avoided (i.e. out from the opening 42). Thus, the S-shaped course of the channel of the connection element 5 causes a damping of disturbing sounds from the opening 42.

[0354] The embodiments explained above are further implemented by means of subsequent explanations.

[0355] FIG. 28 shows a perspective view of a part of an exemplary internal construction of the stimulation device 1 of the sixth or seventh embodiment. The basic concepts of the invention explained below can be used in each present aspect and in each present embodiment and are correspondingly combined. An eccentric cam is mounted on the axis 61 of an electric motor 6, said eccentric cam engaging in an appendage of a flexible wall 31. The (DC current) motor has two poles 67 and 68. Furthermore, the motor 6 is fixed on a motor bracket 65, which has a straight-line course on both sides such that the motor bracket 65 can be inserted in a groove-like, internal guide of the housing 8 (preferably from the back). In the same way, the bracket 32 of the first chamber 3 is fixed on the motor bracket 65, for example it is adhered or screwed on (this is labelled in a hatched manner in FIG. 26).

[0356] FIG. 29 shows a cross-section of the construction of FIG. 28 in the longitudinal direction. The first chamber 3 has a volume V. A lateral or radially arranged opening 33 of the first chamber 3 initially leads into a straight-running channel section of the connection element 5. Furthermore, the channel 53 runs in an S-shaped manner in the direction of the second chamber 4. The material of the damping element 54, in which the S-shaped channel section is formed, is preferably silicone or rubber. The damping element 54 constitutes a section of the connection element 5. Thereafter, the S-shaped channel 53 opens into the second chamber 4 via the opening 51. The second chamber 4 is initially formed to be cylindrical, and opens away from the opening 51 opposite the end of the second chamber 4 in a truncated conical manner. Furthermore, the alignment axis 81 is arranged to be at least parallel, preferably coaxial, in relation to the longitudinal axis 80 of the stimulation device 1 (said longitudinal axis preferably being arranged centrally).

[0357] Thus, the damping element 54 arranged in the longitudinal direction 80 between the first chamber 3 and the second chamber 4 or the opening 42 not only serves for the current-technical/acoustic damping of noises in the medium in the manner of a silencer, but also for the damping of vibrations or oscillations, which are present in the solid body, for example in the bracket 32 or the motor bracket 65, for example, or are forwarded in these. Here, these vibrations or oscillations are damped in the direction of the opening 42. Thus, the damping element presently has a double function of damping oscillations or vibrations in the fluid and in the solid medium in the direction of the opening 42. Consequently, the ergonomics of the stimulation device 1 according to the invention are improved.

[0358] The damping element 54 further has a bracket 55 that can be plugged for simple insertion in the stimulation device 1.

[0359] In this embodiment, the placing region 43 is a comparably narrow surface, which closes the peaked (peripheral) front end 90 of the stimulation device 1.

[0360] FIGS. 30 to 32 show a cross-sectional view in the longitudinal direction 80, a view from behind and a view from in front of the damping element 54 according to the invention respectively.

[0361] In order to keep the housing construction as compact as possible in the cross-sectional direction of the housing 8, the cross-section of the straight-running channel section and the corresponding (back) opening of the damping element 54 on the side II of the first chamber 3 is here formed to be oval. The (front) opening of the damping element 54 on side I of the second chamber 4 is formed to be round. Here, the diameters F and G of the two openings are calculated in such a way that the cross-sectional surface areas of the two openings are (at least approximately) the same. The channel of the damping element 54 thus changes its cross-sectional shape, without changing the cross-sectional surface area. Thus, current losses are kept as marginal as possible, while the stimulation device 1 can be kept compact in terms of the cross-sectional direction.

[0362] FIG. 33 shows a perspective view of the first chamber 3 of the sixth and seventh embodiment from outside, having the flexible wall 31, having the oval opening 33 (that has already been explained in more detail above) that has the corresponding straight running channel section 52 and the bracket 32. The flexible wall 31, which consists, for example, of silicone, has an appendage (protruding upwards in FIG. 33), which has a hole for receiving the eccentric cam appendage. A donut-shaped or ring-shaped transition element 34 is inserted into this hole, said transition element 34 having an internal hole in which the appendage of the eccentric cam is inserted (which is not depicted in more detail). This transition element 34 consists preferably of rubber or a damping silicone. Thus, oscillations or vibrations, which occur on the motor side, are significantly damped before they are transferred into the medium in the first chamber 3 via the flexible wall and would be able to be perceived as disturbing noises outside the stimulation device 1. Thus, it has been shown that the flexible wall 31, similar to a membrane (among other things, because of its flat design) is prone to transferring vibrations or oscillations of the motor axis 61 or the eccentric came to the medium of the chamber 3. Thus, it is presently advantageous to insert the transition element between the flexible wall 31 and the eccentric cam or the motor shaft 61 in order to dampen disturbing vibrations or oscillations before they are coupled into the medium in the first chamber 3.

[0363] FIG. 34 shows a system having one of the embodiments of the stimulation device 1 according to the invention. Thus, a bracket 110 has at least two forked bracket arms 111, into which the stimulation device 1 is placed. The bracket arms 111 are connected to bracket foot 115 via bracket legs 114, said bracket foot 115 preferably being formed to be even and flat. In at least one of the bracket legs, there is a bracket-side charging coil or inductor. Correspondingly, the stimulation device 1 according to the invention has a stimulation device-side charging coil or inductor. If the stimulation device 1 is placed in the bracket arms 111, a (known) inductive coupling between the stimulation device 1 and an electronic power device (that is not shown in more detail) can take place via the coils (that are preferably paired). Thus, a battery of the stimulation device 1 can be charged wirelessly or without cables, without a bushing or a connection to or in the housing 8 being required. This simplifies, for example, a waterproof formation of the housing 8.

[0364] FIG. 35 shows an alternative system having a bracket 110 for charging the stimulation device 1 according to the invention. Here, the stimulation device-side charging coil or inductor can be advantageously housed in the back end 91 of the stimulation device 1. This facilitates a suitable weight distribution and setting of the centre of mass MP of the stimulation device 1. In addition, (convenient) coils are preferably formed to be circular, whereby these can be advantageously stored to be compact with the central axis of the coil in the coaxial (or alternatively parallel) alignment in terms of the longitudinal axis 80 in the housing 8. A cup shaped device, for example a simple water glass, is provided as the bracket 110, in which the pin-shaped stimulation device 1 can be simply placed. This has the advantage that the bracket 110 can be cleaned quite easily. In the plate or platter-shaped bracket foot 115, the bracket-side loading coil or inductor is housed, on which the bracket 110 is placed. If the stimulation device 1 is placed into the bracket 110, a (known) inductive coupling between the stimulation device 1 and an electronic power device (not shown in more detail) can take place by means of the (preferably paired) coils mentioned above. Correspondingly, the battery of the stimulation device can also be supplied with energy and charged by means of this bracket 110 without cables or in a wireless manner.

[0365] FIG. 36 shows a fourth aspect of the invention having an alternative construction of the pressure field generation device 2. Here, the second chamber 4, several connection elements 5, and partial sections of the wall 31 of the first chamber 3 are formed to be one piece. Alternatively, the pressure field generation device 2 can also be constructed from individual parts in two or more parts by adhering to the geometric model of FIG. 36, depicted in a similar way to in FIG. 21, 22 or 25.

[0366] The volume change of the first chamber 3 here takes place in a manner similar to a piston pump, however, here, possible valves are lacking. Thus, a piston 63 is moved backwards and forwards by the drive unit, for example an electric motor or electromagnet, in the directions of the double arrow D. This kind of drive has the advantage that the volume of the first chamber 3 can be reduced to zero or virtually to zero in a simple manner, and thus the first chamber 3 can be almost completely emptied.

[0367] The design of the connection element 5 having several channels 52 and openings 51 leads to a distribution of the pressure field on several concentration points. While the design of the connection element 5 having only one channel, as described in connection with FIG. 25, for forming a significantly concentrated pressure field leads towards a target region, the media or air flow can be distributed on several target regions with the design of the connection element 5 shown in FIG. 36. Thus, the clitoris 12 can be blown onto not only on its glans, but from several sides in equal measure. This distribution of the concentration of the air current on several regions can, depending on the application, help to avoid an overstimulation, and/or help to enlarge the stimulation region.

[0368] FIGS. 37 a) to 37 c) show a fifth aspect of the invention having (partial) cross-sections of a construction of the pressure field generation device 2 having a bending element 64 as a drive for changing the volume of the first chamber 3. The bending element 64 can be a conventional piezoelectric bending element, for example, which is deformed or bent after application of tension. In this aspect of the invention, the wall 31 of the first chamber 3 is constructed to be rigid or stiff, while the bending element 64 is adjusted to the sides of the first chamber 3 in a suitable manner. Here, the transition points between the bending element 64 and the wall 31 are sealed (for example elastically adhered). With this construction, the drive for the pressure field generation device 2 is already integrated into this and an external drive is not necessary. For example, an electric motor having the eccentric cam is not necessary. As a result, among other things, potentially disturbing individual oscillations can be reduced because of the movement of the eccentric cam of the stimulation device.

[0369] FIG. 37 a) shows the pressure field generation device 2 having the bending element 64 in the neutral position in detail. Thus, the volume of the first chamber 3 having the bending element 64 in the neutral positions is the standard volume. FIG. 37 b) further shows the first chamber 3 having an energised bending element that is successively bent outwards, which is why the volume of the first chamber 3 is enlarged; and, as a result, a negative pressure prevails in the pressure field generation device 2. FIG. 37c shows an opposingly energised bending element of the first chamber 3 in comparison to FIG. 10b, which is why the volume of the first chamber 3 is reduced; and in succession, a positive pressure prevails in the pressure field generation device 2.

[0370] FIGS. 38 a) to 38 f) show different views from below and the side of further aspects of the second chamber 4 of the present invention. FIG. 38 a) shows in detail a view from below of a circular second chamber 4, having a centrally arranged opening 51; FIG. 38 b) shows a view from below of a triangular second chamber 4 having a centrally arranged opening 51; FIG. 38 c) a view from below of an oval second chamber 4 having a centrally arranged opening 51; and FIG. 38 d) a view from below of an approximately octagonal second chamber 4 having two openings 51 arranged offset relative to the centre. FIG. 38 e) further shows a side cross-section of a second chamber 4 according to the invention, wherein the second chamber 4 additionally has an extended contact surface 43 with the skin or resting part 43 or placing region 43 in order to improve the sealing (off) function of the second chamber 4 on the skin. The extended contact surface 43 can additionally have grooves or projections, which yet further improve the sealing function. FIG. 38 f) shows a side cross-section of a second chamber 4 having several separated connection elements 5 and an extended contact surface because of the resting part 43 or the placing region 43.

[0371] Thus, the shape of the second chamber 4 can be fundamentally adjusted to the anatomy of the erogenous zone to be stimulated. Here, the shape of the chamber 4 of FIG. 38 a) is adjusted, for example, to the round shape of the breast, while the shape of the chamber 4 of FIG. 38 c) is better adjusted to the shape of the female vulva. Furthermore, the shape of the second chamber 4 additionally also determines the characteristic of the pressure field according to the invention. Thus, the size of the second chamber 4 determines the extent of the achievable negative or positive pressure, in relation to the volume displaced by the first chamber 3. Furthermore, the intensity of the massage effect according to the invention can be set to this via the proximity of the opening 51 of the connection element 5 to the region of skin to be stimulated. The massage effect can also be distributed across several regions by means of several openings 51, cf. FIG. 38 d). Thus, the clitoris, for example, can be stimulated less directly on the very sensitive clitoral glans (cf. FIG. 38 e)), but more so on the region surrounding the clitoral glans, in order to avoid excessive excitation of the clitoris.

[0372] FIG. 39 shows a block diagram of an example of a functional construction of an embodiment of the present invention having a control device 7, a drive unit 6, a lighting device 9, an on/off switch 74, operating elements 71, a battery 76 and an external current supply 73. This basic construction of the control device 7 can fundamentally be used in all disclosed aspects and embodiments.

[0373] The control device 7 which has a microcontroller or is hardwired, initially controls the current supply of all users of the stimulation device 1, and optionally a charging/discharging process of the battery 76 and/or battery management. In particular, the control device 7 controls the energisation of the drive unit 6, for example the size of the displacement, the frequency, the modulation, etc.

[0374] Optionally provided operating elements 71 serve to set the operating type of the device, i.e. to set the modulation pattern of the pressure field. The operating elements 71 can be implemented, for example, as at least one push button, as at least one rotation switch, or as at least one touch-sensitive switch. Furthermore, the operating elements 71 can provide optical feedback for activation, for example by means of light diodes (LED) integrated in the switch.

[0375] An optional display 72 serves to inform the user about the device state and/or the setting state. The display 72 can be formed, for example, from a multitude of light diodes or as an LCD display. The information displayed can be, for example, the charging state of an optional battery or the current setting of the modulation pattern.

[0376] Furthermore, the control device 7 can have a memory, in which at least one modulation or stimulation pattern (these are explained in more detail below in the context of FIG. 40 a) to c)) is stored. The drive unit 6 can now be controlled in terms of its energisation depending on the choice of the user of the stimulation device 1 via the operating elements 71 to correspond to this pre-saved stimulation pattern. The stimulation patterns of the pressure field can optionally also be individually constructed and stored by the user via the operating elements.

[0377] A bushing (that is not shown in more detail) can serve the external current supply of the stimulation device 1 via an external plug, which is connected, for example, to an external network adaptor. In order to ensure the waterproofing of the stimulation device 1, a magnetic-inductive transformer can also be provided instead of the bushing, which enables a power transfer into the stimulation device 1 without an electric conductive contact. Preferably, the stimulation device 1 also has a battery, for example a nickel-metal hydride battery (NiMH) or a lithium ionic battery, for operation without cables. Alternatively, a (longer) current supply cable can also be guided out of the stimulation device.

[0378] FIG. 40 a) shows the temporal course of a total pressure p in the pressure field generation device (2) when using this for stimulation. The dotted line states the reference pressure, for example the currently prevailing atmospheric (air) pressure, which is present outside the pressure field generation device (2). If the second chamber 4 is now placed on the body part 11 to be stimulated, this surrounding pressure prevailing at the start, which is also present in the hollow space 10 of the pressure field generation device (2), is somewhat maintained. From then on, it is assumed that the second chamber 4 is placed, in a largely sealing manner, on the body part to be stimulated. After activating the stimulation device, the drive unit 6 is controlled or energised by the control device 7 according to a pre-stored stimulation pattern. Correspondingly, the volume of the first chamber 3 and thus the pressure and the currents in the pressure field generation device 2 change, wherein the pressure changes are consequently modulated to the reference pressure prevailing at the start or the normal pressure. The pressure or stimulation pattern shown by way of example in FIG. 40 a) develops a pulsed, regular pressure field having temporally alternating negative and positive pressures. In phases of the increase of pressure, the erogenous zone to be stimulated is blown on or massaged, while at the time when a negative pressure prevails, the blood flow through the body part 11, for example the clitoris, is encouraged. Thus, time periods exist (labelled with I) in FIG. 40 a)) according to the invention, in which a negative pressure prevails, while, at the same time, the clitoris is indirectly stimulated.

[0379] FIG. 40 b) shows three examples of alternative stimulation patterns. Thus, a pulsed stimulation pattern having high amplitude is depicted in the region labelled with II) is depicted. In the region labelled with III), a pulsed stimulation pattern having low amplitude is depicted. Furthermore, in the region labelled with IV), a stimulation pattern is depicted that is irregular or asymmetric in terms of the temporal sequence and the amplitude. The patterns can be varied depending on bodily effect/use and according to individual wishes.

[0380] FIG. 40 c) shows a further example of an alternative stimulation pattern. Thus, the strength of the pressure can increase with time in order to adjust to the arousal state of the user.

[0381] Below, additional developments of the stimulation device 1 are presented. All presently disclosed features, embodiments, aspects and developments of the stimulation device 1 can be combined with one another in any combination, as long as this is technically feasible for the person skilled in the art.

[0382] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the connection element 5 is a channel whose opening 33 into the first chamber is oval; and wherein the opening 51 of the channel into the second chamber 4 is round.

[0383] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the connection element 5 is at least sectionally an individual straight running channel; and/or the channel of the connection element 5 is rigid; and/or the at least one connection element 5 is formed in terms of current in such a way that, when reducing the volume of the first chamber 3, the resulting current of the medium is aimed at the erogenous zone, preferably at the clitoris 12.

[0384] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the connection element 5 has the damping element 54.

[0385] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the at least one operating element 71 is provided that is provided on the backwards or rear end 91 of the housing 8.

[0386] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the pressure field generated in the second chamber 4 consists of a pattern of negative and positive pressures, which are modulated to a reference pressure, preferably to the normal pressure.

[0387] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the first chamber 3 is connected exclusively to the second chamber 4 in terms of current.

[0388] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the second chamber 4 is produced from a flexible material, preferably from silicone or rubber, and/or is produced from an at least partially transparent material and/or adjusted to the shape of the vaginal labia minora in such a way that it is completely covered by the opening 42 of the second chamber 4, or the opening 42 of the second chamber 4 can be inserted between the vaginal labia minora.

[0389] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the second chamber 4 having the connection element 5 and the first chamber 3 is formed to be one piece. The wall of the hollow space 10 can also be provided to be one piece.

[0390] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the second chamber 4 of the stimulation device 1 is arranged to be exchangeable.

[0391] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the second chamber 4 has a resting part 43 or a placing region 43, which enlarges the contact surface 43 of the second chamber 4 on the skin in order to improve a sealing effect of the second chamber 4.

[0392] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the stimulation device 1 has at least one operating element 71, by means of which the modulation of the pressure field can be set.

[0393] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the stimulation device 1 has a lighting device 9, preferably an LED lighting device for lighting the second chamber 4.

[0394] The stimulation device 1 according to a further aspect of the invention can be provided, for example, in such a way that the connection element 5 has an inner shaping and an opening to the second chamber 4 which is formed in such a way that the pressure field is modulated in direction and characteristic.

[0395] For example, a method for stimulating body parts, in particular the clitoris (12) can be provided, which has the following steps: [0396] constructing a pressure field aimed at the body part (11), wherein [0397] the pressure field consists of a pattern of negative and positive pressures, which are modulated to a reference pressure, preferably to the normal pressure.

[0398] The method above can be continued by the stimulation device being individually influenced by a modulation of the pressure field.

[0399] Furthermore, the pressure field can be pulsed.

[0400] By means of the stimulation device according to the invention, a method can further be carried out, for example which has the following steps: [0401] placing the second chamber (4) on the body part (11), preferably over the clitoris (12); and [0402] constructing a temporally changing pressure field, which consists of a pattern of negative and positive pressures, which are modulated to a reference pressure, preferably to the normal pressure; and [0403] taking the second chamber (4) off the body part (11).

[0404] Any methods explained in this description do not serve therapeutic or medical purposes, but are only for non-medical and non-therapeutic purposes. Thus, the present method serves for sexual pleasure.

[0405] Similarly, a use of the stimulation device 1 as a sex toy for stimulation of the female clitoris is provided.

[0406] The invention permits further design principles, along with the embodiments explained. Thus, different arrangements or constructions of the first chamber 3 can be combined in any way with different embodiments of the second chamber 4 or the connection element 5.

[0407] Although in all embodiments only one first chamber 3 is depicted, two or more first chambers 3 can also be present, which are then correspondingly driven in a simultaneous or time-delayed manner in such a way that these change their volume in order to construct a pressure field according to the invention.

[0408] Although in all embodiments only one opening from the first chamber 3 to the connection element 5 is depicted, several openings for one connection element 5 or even several openings for several connections elements in the first chamber 3 can thus also be present.

[0409] Although in all embodiments specific angles and angle regions are stated, these angles and angles regions can thus also be used in each case in different embodiments.

[0410] The stimulation patterns according to the invention can deviate from the patterns shown in FIGS. 40 a), b) an c), as long as these have a temporal sequence of negative and positive pressures. For example, at the start or after activation of the device, initially, a relatively prolonged negative pressure is constructed (for example, 3 minutes), in order to effectively increased the blood flow to the zone to be stimulated, from which then pulses of negative and positive pressures that slowly become larger in amplitude follow on.
