Low-radiation electromagnetic earpiece
First Claim
1. An electromagnetic earpiece, comprising:
- a housing comprising electrical connections;
a coil configured to conduct energizing current flowing through it, the coil comprising coil ends;
a membrane configured to oscillate as a result of the energizing current; and
internal connection lines that are routed from the coil ends of the coil to the electrical connections on the housing, wherein a first internal connection line is located at a substantially proximate distance to a second internal connection line for a major portion of either the first internal connection line or the second internal connection line routing from the coil ends to the electrical connections;
wherein the coil, the membrane, and the internal connection lines are located within the housing.

Abstract
In an electromagnetic earpiece with a housing in which a coil through which an energizing current flows as well as a membrane are arranged such that the membrane can be excited to vibrate as a result of the energizing current, the parasitic leakage field generated by the electromagnetic earpiece is be reduced. This is accomplished by internally-running connection lines optimally close together between the ends of the coil and the electrical connections of the electromagnetic earpiece so that the leakage field thereby generated is kept optimally low according to the physical principle of a double conductor, producing an advantageous electromagnetic earpiece in a hearing aid device.
