Electromagnetic buzzer is composed of an oscillator, an electromagnetic coil, a magnet, a vibrating diaphragm and a shell.
Electromagnetic buzzers are mainly divided into passive electromagnetic buzzers and active electromagnetic buzzers.
After the power supply is turned on, the audio signal current generated by the oscillator passes through the electromagnetic coil, causing the electromagnetic coil to generate a magnetic field. The vibrating diaphragm vibrates and sounds periodically under the interaction of electromagnetic coil and magnet.
Electromagnetic buzzer by electromagnetic force driven metal diaphragm sound, high sensitivity, small size. It is suitable for warning sound of electrical products and electronic products. Active buzzer contains audio oscillator circuit, connected to the DC power supply can emit "beep ----" sound. Passive buzzers need to input audio signal current to sound.
