• What is magnetic buzzer?

  Electromagnetic buzzer is a kind of buzzer, which is different from piezoelectric buzzer. Electromagnetic buzzer is an electronic buzzer that makes sound by using the effect of electromagnetic coil on buzzer, which is used as a sound device for electronic products. The active (self-excited) buzzer vibration coil and oscillation coil are combined into one.

  FBelec buzzers are divided into two categories: piezoelectric and Electro-magnetic Buzzer: piezoelectric buzzers make sound by driving the vibration of metal sheets with the piezoelectric effect of piezoelectric ceramics. Magnetic Audio Buzzer uses the principle of electromagnetism to suck down the metal diaphragm when powered on and bounce back according to the elasticity of the diaphragm when powered off. Therefore, the piezoelectric buzzer is driven by square wave and the electromagnetic buzzer is driven by 1 / 2 square wave. The piezoelectric buzzer needs a relatively high voltage to have enough sound voltage. Generally, it is recommended to be more than 9V. Some specifications of piezoelectric can reach more than 120dB, and larger sizes can easily reach 100dB.

  Electromagnetic buzzer: with 1.5V, it can emit sound pressure of more than 85dB, but the consumption current will be much higher than that of piezoelectric buzzer. When the size is the same, the response frequency of electromagnetic buzzer can be relatively low; The sound pressure of electromagnetic buzzer is generally up to 90dB Mechanical buzzer is a small category of electromagnetic buzzer.
