The piezoelectric buzzer has a simple structure in which a ceramic piezoelectric disk is affixed to a vibrating plate. An alternative voltage applied to this element will cause a contraction or diametrical expansion of the element. This feature is used to fold a vibrating plate, which generates sounds. 2x Passive Buzzer 5V features:

- Input voltage: 3V to 12V
- Diameter: 12mm
