This principle is working on this microphone. More details can be seen in the picture. A coil attached to a thin membrane, in such a way as to be positioned in a magnetic field. When the membrane vibrates, the coil will move, because the influence of the magnetic field appears electrical signal. the signal is nothing but the sound of people talking in front of the microphone.
