Magnetic Buzzer Structure-How Magnetic Buzzer Working ?

Magnetic Buzzer Structure


This illustration highlights the structure of a typical magnetic buzzer. Like piezo technology, magnetic buzzers are available in transducer and indicator configurations. In a magnetic buzzer, the transistor acts as the driving circuit. Indicators include the transistor, creating a tone when a dc voltage is applied. Transducers lack this transistor, requiring a square wave signal to operate properly.
