Patent attributes
Embodiments of the present disclosure disclose a stimulation device. The stimulation device includes a pressure generator comprising a chamber including a bottom wall and an opening configured to engage a portion of a body of a user, a drive unit, and a linear reciprocating mechanism. The drive unit is configured to cause reciprocating motion of the bottom wall via the linear reciprocating mechanism, thereby resulting in a changing volume of the chamber. The pressure generator further comprises a stationary sleeve and a motional sleeve, with motional sleeve disposed between the stationary sleeve and the bottom wall, such that, stationary sleeve and the motional sleeve are concentric with each other and define the chamber with the bottom wall.
