From the introduction of previous issues, we know that both piezoelectric buzzer and electromagnetic buzzer can work under the condition of connecting DC voltage, which can be said to be their common point. Today we talk about the differences between the piezo buzzer and magnetic buzzer.Magnetic b

Piezoelectric buzzer, also called piezo audio indicator, can make sound when connected to DC power.

A buzzer or beeper is an audio signalling device, Contain piezoelectric (piezo) buzzer / transducer, magnetic buzzer / transducer and mechanical buzzer, piezo or magnetic buzzer / transducer also contain SMD type, we call them SMD piezo buzzer / transducer and SMD electro-magnetic buzzer / transduce
