12v Piezo buzzer is an electro-acoustic conversion device. Paste the piezoelectric material on the metal sheet, when the piezoelectric material and the metal sheet applied to a voltage across the piezoelectric effect, the buzzer will produce mechanical deformation and make a sound.
Piezoelectric materials are available in a variety of piezoelectric materials used in buzz films are usually high-voltage polarized piezoelectric ceramics.
