摘要: An ultrasonic piezoelectric transducer and an ultrasonic actuator for performing enhanced elliptical vibration comprise a first laminated piezoelectric element having a first fixed end, a resonator mounted to the opposite end of the first laminated piezoelectric element, a second laminated piezoelectric element having one end thereof fixedly mounted to the resonator in a direction other than a vibrating direction of the first laminated piezoelectric element, and a load mass fixedly mounted to the opposite end of the second laminated piezoelectric element. This structure permits the enhanced elliptical vibration of the transducer to have a large, controllable amplitude.
