ABSTRACT:
The present invention is a ceramic voice coil assembly for use in a loudspeaker system which includes a ceramic voice coil form which is formed out of a high temperature ceramic material such as Al.sub.2 O.sub.3, BeO or glass and which has an outer surface and an inner surface. The ceramic voice coil assembly also includes transducer windings having a first end and a second end which are formed by a molybdenum-manganese metallization which is disposed on either the outer surface or the inner surface of the voice coil form and lead wires which are mechanically and electrically coupled to the first and second ends of the transducer windings. The lead wires are either brazed or welded to the ends of the transducers windings. The lead wires may be electrically coupled to either an amplifier or a servo drive circuit of a voice coil linear motor.
