Disclosed embodiments provide an improved stimulation device. Embodiments of the improved stimulation device include a cup and a driver. The cup has a cavity surrounded by a rim. In use, a user positions the rim such that an opening to the cavity is over an area to be stimulated (for example, the clitoris). A sealed-, or substantially-sealed, chamber is formed by the cavity walls and the user's skin (surrounding the clitoris). A pressure field is generated in the chamber without generating a pressure below a reference pressure, which is gauge pressure reading of zero. In some embodiments, this is achieved by a driver configured to vary a volume of the cavity in such a way that the varied volume is not larger than an initial volume. In some embodiments, the stimulation device is a sex toy. In some embodiments, the stimulation device is a medical device.

An air pressure massager includes at least one pressure field generating device. The pressure field generating device includes a chamber with at least one first opening, a connecting rod member connected to one end of the chamber, an eccentric member connected to the connecting rod member, a driving unit connected with the eccentric member, a control device configured to activate the drive unit, and an accessory. The first opening is configured to be placed on a portion of a human body. The driving unit drives the eccentric member to move to drive the connecting rod member to move, such that a volume of the chamber is changed to generate a pressure field for stimulating the human body. The pressure field generated in the chamber directly towards the portion of the human body. The pressure field is adjusted by a positive pressure mode and/or a negative pressure mode.

Embodiments of the present invention relate to an improved stimulation device. Embodiments of the improved stimulation device includes a cup and a driver. The cup has a cavity surrounded by a rim. The driver comprises a plate disposed on an underside of the cup, a cam disposed adjacent to the plate, and a motor mechanically coupled to the cam. The driver comprises a cam pin affixed to the cam, and a bearing rotatably disposed on the cam pin. The bearing is mechanically coupled to a lifter. The lifter is mechanically coupled to a linear bearing, enabling a smooth reciprocating back-and-forth motion from the rotation of the motor. A top of the cup swells and unswells during an operation cycle of the driver.

Stimulation devices are disclosed. An example apparatus includes a housing including a chamber. The housing defines an opening to the chamber. The example apparatus includes a flexible material protruding from the opening and configured to sealingly engage a portion of a body of a user including a clitoris. The example apparatus includes a drive unit disposed in the housing. The drive unit is to cause a volume of the chamber to alternate between a first volume and a second volume, the alternating volume of the chamber to cause pressure in the chamber to modulate between positive pressures relative to an ambient pressure and negative pressures relative to the ambient pressure. The modulated positive pressures and negative pressures are to be applied to the portion of the body via the opening.

An example stimulation device includes a housing, a longitudinal axis of the housing being an axis of longest extension along a length of the housing from a first end to a second end of the housing, a first portion of the housing defining an opening to a chamber, a central longitudinal axis of the first portion of the housing extending through the opening, the central longitudinal axis of the first portion of the housing disposed at a non-perpendicular angle relative to the longitudinal axis of the housing; and a drive unit disposed in the housing, the drive unit to cause a volume of the chamber to change to cause pressure in the chamber to alternate between positive pressures and negative pressures relative to an ambient pressure, the alternating positive and negative pressures to be applied to a portion of a body of a user including a clitoris via the opening.

Direct stimulation devices with improved drives are disclosed herein. An example stimulation device for a clitoris includes a stimulation head to contact the clitoris; a linear drive device coupled to the stimulation head and configured to cause the stimulation head to vibrate; a control device configured to control the drive device; a battery to supply power to the control device; and a housing. The control device and the battery are disposed in the housing.

An example device for stimulating a clitoris includes a housing; a drive device configured to provide a drive movement; a pressure chamber at least partially surrounded by a chamber wall; a chamber wall portion forming a portion of the chamber wall, the drive device to cause the chamber wall portion to repeatedly move between different wall positions to cause a chamber volume of the pressure chamber to repeatedly increase and decrease to generate a variable pressure field; a housing opening fluidly connected to the pressure chamber, the variable pressure field to be output via the housing opening in the form of negative and positive pressures; the drive device including a coil device through which an electrical current is to flow, the drive device disposed in a stationary permanent magnetic field and coupled to the chamber wall portion to transmit the drive movement to cause the chamber wall portion to move.

A sexual stimulation method which may comprise a plurality of light sources for photostimulation of the vagina; one or more vibrators for mechanical stimulation of an area of the vagina; a handle; a controller and programmable memory for containing non-transitory instructions for modes of operation and driving the light sources and vibrators of the invention; a vaginal finger; a handle for ease of use; a keypad for user entry of commands; and a charging or programming port. The invention may also comprise sensors that sense physiologic parameters of a user and adjust sexual stimulation parameters to achieve a desired sexual stimulation effect. Blood oxygen level, temperature, pulse rate and muscle electrical activity may be sensed. The invention also may comprise a flexible covering that provides smooth sliding engagement with an area of the vagina of a user.

Disclosed herein is a penile prosthesis device for facilitating a plurality of bodily functions associated with a penis, in accordance with some embodiments. Accordingly, the penile prosthesis device includes a penile prosthesis body, an ejaculation system, and a pump system. Further, a base of the penile prosthesis body is in contact with a groin of a user. Further, the ejaculation system may include a lubrication system. Further, the ejaculation system includes a pocket and a hole leading into the pocket. Further, the pocket is configured for dispersing first fluid through the hole. Further, the pump system includes a reservoir and a balloon. Further, the reservoir is configured for transferring fluid to the balloon. Further, the balloon is configured for inflating based on the transferring. Further, a shaft of the penile prosthesis body is configured for transitioning between a flaccid and an erect state based on the inflating and the deflating.

Embodiments of the invention relate to a device including a pressure field stimulator and a roller massager. The pressure field stimulator has a cup and a driver, where the driver is configured to vary a volume of the cup. The roller massager comprises a flexible sheath and a roller disposed adjacent the flexible sheath. In some embodiments, an enclosure is disposed around the roller where the enclosure includes an opening through which the roller protrudes. In some embodiments, the roller is disposed on a threaded shaft, mechanically coupled to a motor, within the enclosure. The sheath is tightly bound to the enclosure such that the roller presses on the sheath.
