What is a mechanical buzzer?
Mechanical buzzer has high resistance, infinite DC resistance and large AC impedance. It is a narrow-band sound device, which is usually made of piezoelectric ceramic. A large voltage is required to drive, but the current is very small, just a few ma. The power is also very small. Active buzzer with internal oscillation and driving circuit. Power on and it will sound. Passive buzzer, like horn, needs to add alternating audio voltage to make sound, and can also make sounds of different frequencies. However, the sound of the buzzer is bad anyway, so it is often added with square wave instead of sine wave.
What is the function and application of mechanical buzzer?
Fbelec's mechanical buzzer is an electronic buzzer with integrated structure, which is powered by DC voltage. It is widely used as a sounding device in electronic products such as computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and so on.
