Piezoelectric Copper Passive Buzzer Piezo Film Discs Trigger Alarm Drum Sensor
Product Description:
The piezoelectric ceramic buzzer is a device for piezoelectric ceramic chip applications. The more common is to use the wrong, lead oxide formulation after sintering made of titanium, piezoelectric ceramic chip (pzt), because the human ear is the most sensitive to 3khz audio signal, so the production of the resonant frequency of the buzzer is usually designed in about 3khz. In order to improve the low frequency response, a double diaphragm structure is generally used.
