Audio system with inductive transmission and broadband transmission

摘要

The system has left and right hearing devices separated spatially from each other and designed for wireless communication with each other. Each hearing device is provided with a transceiver, which includes a digital broadband pulse transmitter, where bandwidth of the pulse transmitter amounts to 100 megahertz. A base station is structurally separated from the hearing devices. The base station has an inductive transmitter (TX) and a broadband receiver (RX) for transmitting and receiving digitally modulated magnetic field signals to/from the hearing devices, respectively.
