Manufacturer Dgegt Customized High Quality 85dB Thin Piezo Sounder Buzzer Alarm Without Terminal

This piezoelectric buzzer is an electronic device that generates sound using the piezzoelectric effect. When power is connected, the multivibrator starts to oscillate, outputting an audio signal, and the impedance matcher drivers the piezoelectric diaphragm to produce sound.
