る圧電形発音体。A piezoelectric buzzer element is made by laminating a thin piezoelectric ceramic plate to one side of a diaphragm made of a thin metal plate, and the nodes of the resonant frequency are adhesively bonded to the protrusions on the bottom surface of a synthetic resin case that has sound emitting holes on the top surface. In the piezoelectric sounding body, the piezoelectric sounding body is formed by coating a node on the other surface of the piezoelectric buzzer element with a resin material.
