FM radio system for digital and analog communications for hearing assistance devices

摘要

The present disclosure relates to the wireless communication of analog and digital information using a modulator adapted to communicate analog information in an analog mode and to communicate digital information in a digital mode using frequency modulated transmissions. A demodulator adapted to receive the modulated information is provided. The present subject matter can be used with hearing assistance devices to communicate voice and data information. Applications of the system include communications with assistive listening devices, hearing aids, and other hearing assistance devices.

主权项

1. A wireless communication system for wireless communications with a hearing assistance device, comprising:
a modulator in a first device, the modulator including an input analog multiplexer configured to receive analog information and digital information, the digital information received via a limiter, and the input analog multiplexer configured to selectably pass the analog information or the digital information, wherein the frequency modulator is adapted to controllably provide frequency modulated signals from the analog and digital information accessible to the first device; and a demodulator in the hearing assistance device adapted to demodulate the frequency modulated signals and to provide the analog and digital information to the hearing assistance device, wherein the frequency modulated signals are wirelessly transferred from the first device to the hearing assistance device and wherein the hearing assistance device is configured for reception of analog and digital signals.
