AUDITORY TRAINING DEVICE WITH RADIO RECEIVER AND HEARING AID
First Claim
1. In combination with a hearing aid connected by a cord to an earphone, the hearing aid having an input coil to pick up inductive signals from telephones and the like to be amplified and reproduced in audio form at the earphone, a radio receiver with an antenna to pick up radio frequency signals, said radio having an audio frequency signal output, a case to be suspended on a person'"'"''"'"'s body and having a supporting strap to be draped about the person'"'"''"'"'s neck to support the case adjacent the person'"'"''"'"'s upper torso, the case having a lower portion confining the radio receiver and also having an upper portion with an open top and defining an open topped storage compartment of a size in excess of the size of the hearing aid and of such shape and proportions as to securely receive and hold the hearing aid without manual retaining for transport as the person moves about and as to free the person'"'"''"'"'s hands for other activities, the upper portion of the case having an induction coil formed around the outer periphery of the case to surround the case and encompass the hearing aid and input coil thereof in the open-topped compartment in a prefixed relation to produce inductive coupling between the induction coil and the input coil of the hearing aid, the induction coil being operatively connected to the radio receiver to accept the audio frequency signal output therefrom whereby to apply the output signal of the radio by induction to the hearing aid.

Abstract
An auditory training device to be worn by the hard-of-hearing wherein a radio receiver is housed in a case having a chamber into which a pocket-type hearing aid with an input induction coil may be inserted. An output induction coil encircles the chamber and is connected to the output terminals of the radio receiver to generate an electromagnetic field in the chamber. A radio signal transmitted from an instructor is received by the radio receiver and converted to an audio frequency output signal which is conducted to the output induction coil to establish an electromagnetic field in the chamber. The input induction coil of the hearing aid is coupled by the field and the output signal is induced in the input coil of the hearing aid when the hearing aid is in the chamber, thus permitting a hard-of-hearing person to hear the audio frequency output signal over his hearing aid.
