A voice coil (consisting of a former, collar, and winding) is the coil of wire attached to the apex of a loudspeaker cone. It provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. The term is also used for voice coil linear motors, which produce a larger force and move a longer distance but work on the same principle.

Famous quotes containing the word voice:
“If we would enjoy the most intimate society with that in each of us which is without, or above, being spoken to, we must not only be silent, but commonly so far apart bodily that we cannot possibly hear each other’s voice in any case. Referred to this standard, speech is for the convenience of those who are hard of hearing; but there are many fine things which we cannot say if we have to shout.”
—Henry David Thoreau (1817–1862)
