Piezo Buzzer Components

Piezo buzzer components are parts used in the construction and alteration of piezo buzzers. 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 which is driven by a source such as an oscillating electronic circuit. A piezoelectronic 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, to panel mount, to surface mount. They can have a volume range of anywhere from 60 to 1150 decibels, and sometimes beyond.
