Electromagnetic audio and data signaling transducers and systems

An electromagnetic field signal communications system ( 100 ) is based on a specially configured sending transducer ( 30 ), having electrical conductors ( 32 ) wound onto a generally circular core ( 33 ) including an air gap ( 34 ) from which its electromagnetic fields ( 40 ) are generated when excited with input electrical audio or data ( 20 ) signals. The transducer ( 30 ) transmits by projecting these electromagnetic fields ( 40 ) onto adjacent signal receiving transducers ( 51/56 ) that transform the electromagnetic field ( 40 ) into proportional electrical signals. The electromagnetic fields ( 40 ) are transformed by a receiving transducer ( 51 ) located in an adjacent hearing aid device ( 50 ) such that input audio electrical input signals, which are processed by circuitry ( 53 ), bypass the hearing aid microphone ( 52 ) and are routed to the eardrum speaker ( 55 ). The transducer's ( 30 ) effectiveness is due in part to its ability to reduce environmental electromagnetic interference when excited with an electrical excitation signal ( 18 ) in lieu of or in addition to voice or date signals ( 20 ).
