Abstract
A hearing system having a hearing device, including a receiver antenna assembly with a receiver core having a relatively high magnetic permeability and a receiver coil wound around the receiver core, operably connected to a rechargeable power source, and a hearing device charger, including a transmitter antenna assembly, with a transmitter core having a relatively high magnetic permeability and a transmitter coil wound around the transmitter core, operably connected to a power supply. The respective configurations of the hearing device and the hearing device charger may be such that when the hearing device is in a charging position on the hearing device charger, the receiver core and the transmitter core together provides a closed loop path for magnetic flux.
