Abstract
A mobile communication device that is compliant with the Hearing Aid Compliance Act. The device includes a coil and circuitry that can couple, through electromagnetic induction, the output of an audio codec of the device to a hearing aid. The coil and circuitry can also be used to charge the battery of the device. The coil and circuitry can further be used, through electromagnetic induction, to transfer energy from the battery of the device to the battery of the hearing aid to charge the battery of the hearing aid.

14. A method of coupling a mobile communication device to a hearing aid or to an electromagnetic induction charger, the mobile communication device comprising an electrical energy source, an audio codec, and a coil, the method comprising:
-
detecting one of a mobile communication device electromagnetic charge signal generated by the electromagnetic induction charger and a hearing aid identification electromagnetic induction signal generated by the hearing aid; upon detection of the mobile communication device electromagnetic charge signal, electrically connecting the coil to the electrical energy source to provide a charge current to the electrical energy source to charge the electrical energy source, the charge current being a function of an electromagnetic induction current generated in the coil by the mobile communication device electromagnetic charge signal; and upon detection of the hearing aid identification electromagnetic induction signal, electrically connecting the coil to the audio codec to provide an electrical output signal of the audio codec to the coil to generate an electromagnetic induction output signal to be received by the hearing aid.
