The piezoelectric buzzer has a simple structure in which a piezoelectric ceramic disc is stuck on a vibrating plate.
An alternative tension applied on this element will cause a contraction or diametral expansion of the element.
This feature is used to fold a vibrating plate, which generates the sounds.
