Piezo Ultrasonic Transducer is to convert electrical energy into sound energy which also is called ultrasonic.
It is composed of outer shell,matching tier,ring piezoelectric ceramic,backing material,outgoing cable and cymbal.

Piezo Ultrasonic Transducer Features
1,High performance with high mechanical Q.
2,High transfer efficiency.
3,Large amplitude.
4,High quality piezoelectric ceramic material:good heat resistance,large range of working temperature.
5,Lower Resonant Impedance.
