A piezo buzzer is an audio signalling device powered using piezoelectricity, which is created using a material that generates an electric charge when placed under mechanical stress. Piezo buzzers were invented by Japanese manufacturers.

### How do piezo buzzers work?

Piezo buzzers have a piezoelectric element that is driven by a source such as an oscillating electronic circuit. A piezoelectric amplifier will then make the click, ring or beep produced by the buzzer louder.

#### Types of piezo buzzer components

Piezo buzzer components can vary in a number of different ways. They differ in their mounting style, the volume of sound they can produce, and their size. Piezo buzzers can be mounted in a range of ways, from [bracket](/web/c/enclosures-server-racks/enclosures-racking-components/enclosure-mounting-brackets/), to panel mount, to surface mount. They can have a volume range of anywhere from 60 to 115 decibels, and sometimes beyond.



Piezo buzzer components are the parts used in the construction and alteration of piezo buzzers – a type of audio signalling device.
