moving coil

adj

(Electronics) denoting an electromechanical device in which a suspended coil is free to move in a magnetic field. A current passing through the coil causes it to move, as in loudspeakers and electrical measuring instruments, or movement of the coil gives rise to induced currents, as in microphones and some record-player pick-ups
