Patent Images
1. A communication coupling system comprising:
- a sound generation device having a receiver;
a sound transmission line connected to said sound generation device having substantially 125 turns of 35 gauge wire wound around a bar-shaped core of said 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. A communication coupling system comprising:
-
a sound generation device having a housing in which a speaker is mounted, the housing including an earpiece opening proximate the speaker, the speaker presenting a frustoconical horn and a base configured to drive the horn to produce an audio signal when the base is actuated with an electrical signal, the base having a first diameter;
the frustoconical horn presenting an axis of symmetry and having a directional orientation extending forward from said base along the axis of symmetry towards the earpiece opening;
a sound transmission line circuitry in communication with the speaker for delivery of the electrical signal thereto, a toroidal coupler coil mounted on the housing forward of the speaker and circumscribing the earpiece opening, the toroidal coupler coil presenting a symmetrical axis and a second diameter with a transverse orientation with respect to the symmetrical axis, the symmetrical axis and the axis of symmetry being substantially aligned with respect to one another, the second diameter of the toroidal coupler coil being less than the first diameter of the base.
