A hearing improvement device using a multi-coil coupling system and methods for operating such a device are disclosed. An embodiment of the present invention may use an array microphone to provide highly directional reception. The received audio signal may be filtered, amplified, and converted into a magnetic field for coupling to the telecoil in a conventional hearing aid. Multiple transmit inductors may be used to effectively couple to both in-the-ear and behind-the-ear type hearing aids, and an additional embodiment is disclosed which may be used with an earphone, for users not requiring a hearing aid.

The method according to claim 1, wherein the plurality of magnetic field orientations comprises two magnetic field orientations. 3. The method according to claim 1, wherein the first inductor is configured to generate the first magnetic field orientation, and a second inductor is configured to generate the second magnetic field orientation. 4. The method according to claim 1, further comprising: converting sound into the electrical signal representative of sound. 5. The method according to claim 1, further comprising: receiving the electrical signal representative of sound. 6. The method according to claim 1, wherein the hearing improvement device is positioned behind an ear of the user. 7. A hearing improvement system comprising: a hearing aid for directing sound into an ear canal of a user; and a housing arranged to fit substantially behind an ear of the user, the housing comprising: a microphone having a relatively greater sensitivity to sound in the direction faced by the user, the microphone for converting sound into an electrical signal; at least one inductor for producing, using the electrical signal, a magnetic field for coupling to a telecoil of the hearing aid, wherein the at least one inductor comprises at least two inductors each generating a magnetic field having a different field orientation; and a battery. 8. The hearing improvement system of claim 7, wherein the hearing aid is a behind-the-ear type hearing aid. 9. The hearing improvement system of claim 7, wherein the housing further comprises switch circuitry for selecting among the at least one inductor. 10. The hearing improvement system of claim 7, wherein the microphone comprises an array microphone. 11. The hearing improvement system of claim 7, wherein the housing further comprises an amplifier for modifying the electrical signal. 12. A hearing improvement device comprising: an amplifier for modifying an electrical signal representative of sound; at least one inductor for generating, from the modified electrical signal, a magnetic field suitable for coupling to the telecoil of a hearing aid; and a housing suitably arranged for wearing proximate an ear of a user, wherein the housing contains the at least one inductor, the amplifier, and a battery, wherein the housing is suitably arranged to fit behind an ear of a user, and wherein the housing is arranged to be collocated with a behind-the-ear (BTE) type hearing aid. 13. The hearing improvement device of claim 12, further comprising a microphone for converting sound into the electrical signal representative of sound. 14. The hearing improvement device of claim 13, wherein the microphone comprises a directional microphone. 15. The hearing improvement device of claim 14, wherein the microphone is an array microphone. 16.

The hearing improvement device of claim 12, wherein the at least one inductor comprises at least two inductors each generating a magnetic field having a different field orientation. 19. The hearing improvement device of claim 12, further comprising an ear hook for supporting the device from an ear of a user. 20. A hearing improvement device comprising: an amplifier for modifying an electrical signal representative of sound; at least one inductor for generating, from the modified electrical signal, a magnetic field suitable for coupling to the telecoil of a hearing aid, wherein the at least one inductor comprises at least two inductors each generating a magnetic field having a different field orientation; and a housing suitably arranged for wearing proximate an ear of a user, wherein the housing contains the at least one inductor, the amplifier, and a battery. 21. The hearing improvement device of claim 20, further comprising a microphone for converting sound into the electrical signal representative of sound. 22. The hearing improvement device of claim 21, wherein the microphone comprises a directional microphone. 23. The hearing improvement device of claim 22, wherein the microphone is an array microphone. 24. The hearing improvement device of claim 20, further comprising switch circuitry for passing the modified electrical signal to a selected one of the at least one inductor. 25. The hearing improvement device of claim 20, wherein the housing is suitably arranged to fit behind an ear of a user. 26. The hearing improvement device of claim 25, wherein the housing is arranged to be collocated with a behind-the-ear (BTE) type hearing aid. 27. The hearing improvement device of claim 20, further comprising a first electrical connector portion that when mated with a second electrical connector portion enables the passage of the electrical signal representative of sound. 28. The hearing improvement device of claim 20, further comprising an ear hook for supporting the device from an ear of a user.
