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 of a user's body to be stimulated (for example, the clitoris). A sealed-, or substantially-sealed, main chamber is formed by the cavity walls and the user's body (skin surrounding the clitoris). A pressure field is generated in the main chamber. The device includes a voice coil motor that drives a linear actuator. This enables the volume of the cavity, and changes in volume, to be electronically controlled. The change in total volume causes a change in pressure experienced by the user. This allows the user to adjust the pressure based on comfort and pleasure as per user preferences.
