21. Sam Garrett is currently an active composer of both chamber works and music under the name Voice Coils . 22. The majority of loudspeakers use'overhung'voice coils , with windings that are taller than the height of the magnetic gap. 23. The voice coil itself is shaped rather like an arrowhead, and made of doubly coated copper magnet wire. 24. The wire in a voice coil is usually made of copper, though aluminum and, rarely, silver may be used. 25. The voice coil in moving coil drivers is suspended in a magnetic field provided by the loudspeaker magnet structure. 26. Other features include a folding design for convenient carrying and storage, along with copper-clad voice coil and gold-plated plug. 27. Voice coils can be used for applications other than loudspeakers, where time force linearity and long strokes are needed.28. Additional types of motion control devices manufactured by Aeroflex's Motion Control Division are Voice Coils and various other devices. 29. The shaker houses a small weight which is driven by a voice coil similar to those found in dynamic loudspeakers. 30. Circa 1970, diode overload protection was added across voice coils to prevent burnout from clipping produced by an overdriven amplifier.
