The piezoelectric buzzer generates mechanical deformation of piezoelectric ceramic plates by reverse piezoelectric effect, which induces the vibration of vibrators and forms sound wave in the air. This one-piece electronic sound device is widely applied in automotive electronics, security alarming, etc.
