The passive 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 used in the automotive electronics,security alarming,etc.
- Parking alarm system
- Anti-theft alarm system
