VIBRATION ACTUATOR USING DISPLACEMENT INCREASING MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a vibration actuator providing quiet drive noise and a high vibration amount with a thin constitution.

SOLUTION: The vibration actuator is provided having quiet drive noise and a high vibration amount with a thin constitution using a piezoelectric element as a drive source, while maximally increasing the displacement of the piezoelectric element as the drive source, having the structure of converting the displacement increased by a suspension to the displacement in the vibration direction, by using the constitution having drive structure using a lever type displacement increasing mechanism with the suspension disposed in the diagonal direction.
