Product Description
buzzers are divided into two categories: piezoelectric buzzers are piezoelectric and electromagnetic: piezoelectric buzzers use the piezoelectric effect of piezoelectric ceramics to drive the vibration of metal sheets to produce sound; The electromagnetic buzzer uses the principle of electromagnetism to suck down the metal diaphragm when energized and bounces back according to the elastic force of the diaphragm when not energized. Therefore, the piezoelectric buzzer is driven by square wave, electromagnetic type is 1/2 drive,
