Product Introduction of Piezoelectric Ceramic Buzzer

      A piezoelectric ceramic buzzer is a device that uses a piezoelectric ceramic chip. Piezoelectric ceramic sheets (PZT) made of titanium, zirconium oxide, and lead oxide and then sintered are more commonly used. Since the human ear is most sensitive to audio signals at 3kHz, the resonant frequency of the buzzer sheet is usually designed to be around 3kHz during production. To improve the low - frequency response, a double - diaphragm structure is generally adopted.
