  • The sound source of the piezoelectric buzzer sound element mainly comes from the piezoelectric vibrating plate.

    The piezoelectric vibrating plate is composed of a piezoelectric ceramic plate with electrodes printed on both sides and a metal plate (brass or stainless steel, etc.).

    Use an adhesive to bond the piezoelectric vibrating plate and the metal sheet together, which is what we commonly call the buzzer sheet.
