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