I have a couple of piezo buzzers. I applied 5 volts to them but they just make a clicking noise.
These items are new, never used. Any ideas?

Thx much.

 

Hi cm,
It is a piezo resonator, it requires an 4kHz AC drive voltage.

Hello,

It is not a buzzer, but a speaker.

Manufacturer : Mallory Sonalert Products Inc.

Driver Circuitry : Transducer, Externally Driven

Voltage - Rated : 5 V

Voltage Range : 1 ~ 25V

Frequency : 4kHz

It will need an oscillator to produce a tone.
