Piezo passive buzzer need to be connected to the audio output circuit to sound, the advantage is the sound frequency controllable, power consumption is small, generally in 20ma below, not more than 100ma. In general, the piezoelectric buzzer is driven by square wave (VP-P).Piezo passive buzzer has small size, light weight, thin thickness, power consumption, good reliability, low cost. Applicable to electronic watches, pocket calculator, electronic doorbell and electronic toys . Microwave oven, washing machine, air conditioner, blood glucose meter, smoke alarm, reversing radar, tire pressure monitor, coffee machine. Also can be used as sound control toys sound sensor. Mainly used in other fields. The monthly supply of 5 million buzzers, through the ISO, IATF certification.
