Automotive electronic buzzer direct manufacturers, complete style

automotive electronic buzzer direct sales manufacturers, complete styles, buzzer is an integrated structure of electronic buzzer, widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products for the sound device; buzzer is mainly divided into piezoelectric buzzer and electromagnetic buzzer two types. The piezoelectric buzzer is mainly composed of multi-vibrator, piezoelectric buzzer, impedance matching box, resonance box and shell. The multivibrator is composed of a transistor or an integrated circuit. When the power is turned on (1.5~15V DC working voltage), the multivibrator vibrates and outputs an audio signal of 1.5~2.5kHZ. The impedance matching device drives the piezoelectric buzzer to sound.
