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. Passive Buzzer 5V features:

- Input voltage: 3V to 12V
- Diameter: 12mm
- Height: 7.5mm
- Pin spacing: 6.5mm
- Impedance: 16 Ohm
- Working frequency: 2 to 5 KHz
- Quantity: 1 unit
