Piezoelectric Vibrator and Ultrasonic Motor Having Piezoelectric Vibrator

The piezoelectric transducer and the ultrasonic motor having the same are disclosed. And a resilient member having a cross-section of a square, when attached to each side of the elastic member electrical signals are input to a piezoelectric element to oscillate the elastic members in the longitudinal direction and the winding direction, the piezoelectric element has the same size all the elastic members the piezoelectric transducer, characterized in that more long short, the piezoelectric element and to reduce the production time and costs because it has a single polarization direction, as well as the piezoelectric element is to simplify both the simple volume because the vibration at the same time, oscillation it is possible to improve the performance. A piezoelectric element, a piezoelectric vibrator, an ultrasonic motor
