Electronic Magnetic Buzzer 1.5v 3v DC buzzer 85db active 9mm internal drive buzzer

Magnetic buzzer electromagnetic buzzer is composed of oscillator, electromagnetic coil, magnet, vibration diaphragm and shell, etc., after the power supply is switched on, the audio signal current generated by the oscillator passes through the electromagnetic coil, making the electromagnetic coil produce magnetic field. The vibration diaphragm vibrates and sounds periodically under the interaction between the electromagnetic coil and magnet.Electromagnetic buzzer is widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, timers and other electronic products as a sound device.Electric buzzer is the piezoelectric effect of piezoelectric ceramics to drive the vibration of metal sheet and sound;Electromagnetic buzzer, is the principle of electromagnetism, the metal vibration film is sucked down when energized, not energized according to the elastic force of the vibration film, so piezoelectric buzzer is driven by square wave, electromagnetic is 1/2 square wave drive, piezoelectric buzzer needs a relatively high voltage to have enough sound pressure, generally recommended for more than 9V.Some piezoelectric specifications can reach more than 120dB, and the larger size can easily reach 100dB.Electromagnetic buzzer: with 1.5v can send out 85dB above sound pressure, only the consumption of current will be significantly higher than the piezoelectric buzzer, and in the same size, electromagnetic buzzer, response frequency can be done relatively low;The sound pressure of electromagnetic buzzer is generally up to 90dB. Mechanical buzzer is a small category of electromagnetic buzzer.
