  • Patent number: 5337364
    Abstract: A communication device for transmitting audio information includes a compact casing which houses processing circuitry. The processing circuitry converts input audio signals into transducer driving signals. A miniaturized microphone is mounted in the casing for receiving the input audio signals. The input audio signals are then amplified and filtered to appropriate signal levels by the processing circuitry. Once the input audio signals have been processed in this manner they are applied to a driver which outputs transducer driving signals analogous to the input audio signals. The transducer driving signals are received by a transducer assembly worn by a user and energize a pair of coils located on opposite sides of an armature forming part of the transducer assembly. The electromagnetic forces generated by the coils when energized cause the armature to move. Movement of the armature in turn drives a plunger so that the plunger moves in a vibrational pattern analogous to the input audio signals.
