What is magnetic buzzer ? Magnetic buzzer HCM1212X ,HCM1205X

Magnetic buzzers use a coil wrapped around a pole. A metal plate is mounted a short distance from one end of the pole. The coil creates a magnetic field in the pole which attracts the plate, but since the plate is fixed the center flexes towards the pole. As the electrical signal varies, the magnetic field varies and the plate vibrates.
