The auto electronic buzzer is a direct selling manufacturer with complete style. The buzzer is an integrated electronic signal. It is widely used in the electronic products such as computer, printer, copier, alarm, electronic toy, automobile electronic equipment, telephone, timer and other electronic products. The buzzer is mainly divided into piezoelectric buzz. Two types of devices and electromagnetic buzzer. The piezoelectric buzzer is mainly composed of a multivibrator, a piezoelectric buzzer, an impedance matching device, a resonance box and a case. A multiharmonic oscillator is composed of a transistor or an integrated circuit. When the power is switched on (1.5~15V DC voltage), a multi harmonic oscillator vibrate and output a 1.5 to 2.5kHZ audio signal. The impedance matching device drives the sound of the PZT.
