ABSTRACT:
In a vibrating actuator device, a driving force is obtained by applying AC signals having different phases to first and second electromechanical energy transducers disposed in a vibrator. The state of driving of the device is determined by comparing the value of a voltage of the AC signal in the first electromechanical energy transducer with the value of a voltage of the AC signal in the second electromechanical transducer.
