Abstract
Various embodiments described herein provide a mechanism for transducing transverse vibrational energy into an elastic body of a sexual stimulation device by directly driving the transverse modes of vibration of the elastic body. Additionally, by using an actuator that transduces a force that is proportional to the input current or voltage, the vibration may be driven with any arbitrary waveform.
Claims20
A sexual stimulation device comprising:
- an elastic body comprising a distal end, a proximal end, a body length along a longitudinal axis, and a hollow bore extending from said proximal end along said longitudinal axis of said elastic body for a projection distance of less than 50% of said body length, said elastic body exhibiting mechanical resonance at a resonant frequency that corresponds to a transverse mode of vibration of said elastic body;
- a rotary voice-coil actuator abutting said elastic body so as to facilitate said elastic body to resonate in said transverse mode of vibration in response to an input current, said rotary voice-coil actuator comprising:
- a transverse pivot that is oriented perpendicular to said longitudinal axis;
- a rotor arm that pivots about said transverse pivot and projects through said hollow bore for said projection distance so as to mechanically couple a distal end of said rotor arm with an internal drive surface of said hollow bore;
- and
- a magnetic assembly that is coupled with a proximal end of said rotor arm so as to generate, in response to said input current, an oscillating force that is perpendicular to said longitudinal axis, said oscillating force being imparted into said elastic body via said distal end of said rotor arm and said internal drive surface;
- a controller configured to obtain, generate, and/or process an input signal;
- and
- a power amplifier that is electrically coupled to said rotary voice-coil actuator, operationally coupled to said controller, and configured to generate said input current according to said input signal.
