What’s Inside

Mechanical Buzzers is a Solid State circuit which is self-oscillating that converts the electrical energy to a magnetic field. As the magnetic field is turning on and off it changes the magnetic field polarity in the coil. The membrane includes a miniature permanent magnet which reacts with the coil magnetic field pulling or pushing the membrane and producing the sound.
