Single driven ultrasonic elliptical vibration transducer

The present invention discloses a single ultrasonic elliptical vibration exciting transducer comprises an ultrasonic vibration transducer and elliptical vibration mode transducer. The ultrasonic vibration transducer comprises a bolt and a rear cover plate are sequentially provided on the bolt, piezoelectric ceramics, and the electrode sheet front cover, the front cover is coupled by a screw and bolt the rear cover, the piezoelectric ceramic sheet, and the front electrode sheet pressing plate is fixed; the elliptical vibration mode transducer provided on the front of the front end of the cover, which is cylindrical overall, three cutout defines a rectangular upper and lower sides of the distribution of the dislocation, the ultrasound may be longitudinal ultrasonic vibration of the vibration generated by the transducer into a buckling compound ultrasonic elliptical vibration. The present invention uses a sandwich structure, having a large power capacity, simple structure, high energy conversion efficiency, the advantages of stable performance.
