Pressure field stimulation device
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.

a cup formed of a flexible resilient material comprising a cavity, wherein the cavity is defined by an interior lateral wall and a base, wherein the base has a side inside the cavity and a side outside the cavity; and
a driver, the driver comprising:
a plate mechanically coupled to the base of the cup on the side outside the cavity;
a cam disposed adjacent to the plate;
a cam pin extending from the cam;
a bearing disposed on the cam pin;
a motor mechanically coupled to the cam;
a lifter mechanically coupled to the bearing, said lifter also mechanically coupled to the plate; and
a linear bearing, the linear bearing mechanically coupled to the lifter.
2. The stimulation device of claim 1 , wherein the linear bearing is mechanically coupled to the lifter to enable reciprocating linear motion.
3. The stimulation device of claim 1 , wherein:
the driver is configured to vary a volume of the cavity of the cup from a first volume to a second volume.
