Vibratory actuator and device for sexual stimulation

Abstract

A device for sexual stimulation includes: a support structure defining a centerline; a first vibratory actuator including a first motor, a first output shaft, and a first eccentric mass coupled to the first output shaft, the first vibratory actuator elastically coupled to the support structure opposite the first eccentric mass in a cantilever configuration; a second vibratory actuator including a second motor, a second output shaft, and a second eccentric mass coupled to the second output shaft, the second vibratory actuator elastically coupled to the support structure opposite the second eccentric mass in a cantilever configuration, the first vibratory actuator and the second vibratory actuator substantially parallel and arranged on opposing sides of the centerline; and a sheath including a first section arranged over the first vibratory actuator, a second section arranged over the second vibratory actuator, and a third section arranged over a portion of the support structure.

We claim: 
     
         1 . A vibratory actuator for a sexual stimulation device, comprising:
 a motor comprising an output shaft;   an eccentric mass coupled to the output shaft;   a housing enclosing the eccentric mass and the output shaft;   a first isolator coupled to the motor opposite the output shaft and configured to engage a groove on a support structure to pivotably couple the motor to the support structure; and   a second isolator coupled to the motor adjacent the first isolator and configured to contact a surface of the support structure to define a pivot endstop.   
     
     
         2 . The vibratory actuator of  claim 1 , wherein the first isolator comprises an o-ring of a first outer diameter and a first cross-sectional area, and wherein the second isolator comprises an o-ring of a second outer diameter less than the first out diameter and a second cross-sectional area less than the first cross-sectional area. 
     
     
         3 . The vibratory actuator of  claim 1 , wherein the first and second isolators are configured to passively damp communication of vibrations, generated by the motor and eccentric mass, into the support structure.
