ABSTRACT:
An armored voice coil assembly comprises a former that is impregnated with a curable resin, preferably polyimide resin. Voice coil wire is wound around the outside surface of the former and is then preferably encased with an outer layer of resin impregnated glass fabric wrapped around the voice coil windings, effectively enveloping the voice coil within inner and outer layers of fabric and resin. The armored voice coil assembly is then cured into a solid shape.
