  • The working principle of the Piezoelectric Ceramic Chips:

    The sound source of the sound element of the Piezo Ceramic Bimorph mainly comes from the piezoelectric vibration plate. The piezoelectric vibration plate consists of a piezoelectric ceramic plate with electrodes printed on both sides and a metal plate (brass or stainless steel, etc.). Using adhesive, the piezoelectric vibration plate and the metal sheet are bonded together, which is what we commonly call the buzzer sheet. Typically, piezoelectric vibrating plates are installed in resonant chambers to generate high sound pressure. Most buzzer chips in China are produced by FBelec, FBelec will always be your first choice
