What Is a Piezoelectric Buzzer?
A piezoelectric buzzer is an audio-generating component, primarily composed of piezoelectric ceramics, leads, and a resonance chamber.
The mechanism of sound generation is based on the repeated flexural vibrations caused by the expansion and contraction of the piezoelectric ceramics. The manufacturing process is relatively simple, and its shock resistance makes it suitable for use in harsh environments. Notably, a Piezoelectric Buzzer is characterized by its high safety and low power consumption.
When installed on a printed circuit board with a bit of space, it can produce a clear electronic sound. Piezoelectric buzzers are commonly used in components for GPS systems and the motherboards of tablet PCs.
