Title: Receiver system for receiving audio electrical signals

Abstract: A receiver system includes means for electromagnetically coupling audio bandwidth information signals from an induction loop to a miniature induction receiver/transducer. The induction loop is shaped to be worn around the neck of a wearer. The receiver/transducer is physically shaped for placement in the mouth of the wearer. In response to the varying magnetic induction field generated by the induction loop, the audio bandwidth information signals are amplified by the receiver and converted into substantially linear mechanical movement by the transducer. The output of the transducer is propagated mechanically, directly to the inner ear mechanism, via the teeth and gums of the wearer whereby the wearer perceives the message content of the audio bandwidth information signals without the use of conventional outer ear mechanism.
