PCB coil for hearing aid compatibility compliance
First Claim
1. A wireless phone, comprising:
- a wireless transceiver configured to facilitate wireless transfer of signals containing audio information, the wireless transceiver configured to receive signals containing audio information;
a processing circuit coupled to the wireless transceiver and configured to receive audio data based on the audio signals received by the wireless transceiver and provide output audio signals based on the audio data; and
a coil formed in a circuit carrying element, the coil configured to receive a signal based on the output audio signals from the processing circuit and to at least provide an output signal receivable by a hearing aid that is not intelligible by a human ear.

Abstract
A wireless phone includes a wireless transceiver that facilitates wireless transfer of signals containing audio information. The wireless transceiver receives signals containing audio information and a processing circuit coupled to the wireless transceiver receives audio data based on the audio signals and provides output audio signals. The phone also includes a coil formed in a circuit carrying element (e.g. circuit board). The coil receives a signal based on the output audio signals from the processing circuit and, in response, provides an output signal receivable by a hearing aid that is not intelligible by a human ear. The coil may be one of multiple coils of a coil system formed in multiple layers of the circuit carrying element.
