Abstract
An electromechanical transformation device has a magnetostrictive actuator and a driving device that drives the magnetostrictive actuator. The driving device drives the magnetostrictive actuator based on any one of the vibration signal and the audio signal or mixed signal of them.
Claims8
An electromechanical transformation device comprising:
- a magnetostrictive actuator;
- and
- a driving device configured to drive the magnetostrictive actuator, based on an audio signal, selectively combinable with an independent vibration drive signal,
- wherein the intensity of the independent vibration drive signal is adjusted in accordance with a level of the audio signal.
