A coil of wire wrapped around a tube (coil form) attached to the speaker cone or driver diaphragm. The coil becomes an electromagnet when an audio signal is applied; this interacts with a permanent magnet and causes the cone or diaphragm to vibrate.   Back   Back   Home  |  Contact Us  |  About Us  |  Advertise  |  Car Audio How to Links  |  Join!  [..]

the wire wound around the speaker former. The former is mechanically connected to the speaker cone and causes the cone to vibrate in response to the audio current in the voice coil.

(electronics) A coil of wire attached to the apex of the cone of a loudspeaker that provides the motive force to the cone by the reaction of a magnetic field to the current passing through it. (el [..]
