Hearing aid with wireless battery charging capability
First Claim
1. A hearing aid, comprising:
- a set of battery charging terminals configured to be connected to a battery;
a receiver oscillator circuit electrically coupled to said set of battery charging terminals, said receiver oscillator circuit having a receiver coil tuned to resonate at a resonance frequency in a range of MHz, and at the resonance frequency said receiver coil configured to receive magnetic energy in a form of electromagnetic waves of a frequency similar to the resonance frequency of said receiver coil and to convert the magnetic energy of the electromagnetic waves received to an electrical current to charge the battery via said set of battery charging terminals; and
a coating partially surrounding said receiver coil.

Abstract
In an embodiment, a hearing aid is provided. The hearing aid may include a set of battery charging terminals configured to be connected to a battery. A receiver oscillator circuit is electrically coupled to the set of battery charging terminals, the receiver oscillator circuit includes a receiver coil. The receiver coil may be tuned to resonate at a resonance frequency in a range of MHz and at the resonance frequency. The receiver coil may be configured to receive magnetic energy in the form of electromagnetic waves of a frequency similar to the resonance frequency of the receiver coil and to convert the magnetic energy of the received electromagnetic waves to an electrical current to charge the battery via the set of battery charging terminals.
