Moving Coil Microphone
PrintOverview
A moving-coil microphone contains a diaphragm exposed to sound waves. The diaphragm carries a coil placed in the magnetic field. The voltage induced in the coil is proportional to its amplitude of vibration, which, in turn, depends on the sound pressure.
Moving-coil microphone. AP = acoustic pressure, Uo = output voltage, 1 = diaphragm, 2 = coil, 3 = permanent magnet, 4 = protection grid, 5 = case.
