ABSTRACT:
An oscillatory-wave actuator is provided capable of simplifying the structure of a driving circuit. Push-up vibration is formed in an oscillating body including three piezoelectrics and an elastic body by applying an AC voltage to the first piezoelectric. The second piezoelectric outputs a vibration-detecting voltage according to the amplitude of the push-up vibration, and the third piezoelectric receives the vibration-detecting voltage and generates torsional vibration in the oscillating body. As a result, a traveling oscillatory wave can be formed in the elastic body by use of a single-phase driving voltage (AC voltage).
