What is Piezo Buzzer,Piezo audio indicator ?
The heart of piezo buzzers are a piezoelectric ceramic plate. Piezoelectric ceramics generate electricity when they experience mechanical force and, more important to a buzzer’s function, create force when exposed to an electric field. When the ceramic experiences an alternating voltage, the plate extends and shrinks. It is glued to a fixed metal plate so these forces cause the ceramic to flex, creating the buzzing sound.
