Apparatus for communication coupling with a hearing aid
An improved communication coupling device having a coupler coil with about 125 turns of wire about a bar-shaped core for use with a hearing aid having a hearing aid coil to accommodate individuals with various degrees of hearing loss to use a sound generation device such as a telephone.
1. A communication coupling system comprising:
a sound generation device having a receiver;
a sound transmission line connected to said sound generation device, said sound generation device having substantially 125 turns of 35 gauge wire wound around a bar-shaped core of a coupler coil in two or more layers, wherein the layers are wound in alternating clockwise and counter-clockwise directions;
a hearing aid coil located in a hearing aid; and
a speaker located in said sound generation device.
2. The communication coupling system of claim 1 , wherein said core of said coupler coil comprises ferrite.
3. The communication coupling system of claim 1 , wherein said speaker is powered by a speaker connection and said coupler coil is powered by said speaker connection.
4. The communication coupling system of claim 1 , wherein said sound generation device is selected from the group consisting of a standard telephone, a cell phone, an earpiece connected to a telephone, a headset connected to a telephone, an electronic audio headset, an earpiece connected to a CD player, and an earpiece connected to a computer.
5. The communication coupling system of claim 1 , wherein said wire includes beryllium.
6. The communication coupling system of claim 1 , wherein at least part of said receiver comprises said coupler coil.
7. The communication coupling system of claim 1 , wherein said sound generation device includes a front surface, and further wherein said coupler coil is adjacent to said front surface.
8. The communication coupling system of claim 1 , wherein said coupler coil comprises an encapsulation.
9. A communication coupling system of claim 1 , wherein said sound generation device comprises a telephone having a handset and said coupler coil is located in said handset.
