Pressure field stimulation device
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.
