HEARING AID WITH WIRELESS BATTERY CHARGING CAPABILITY
摘要
<p>In an embodiment, a hearing aid (104) is provided. The hearing aid (104) may include a set of battery charging terminals (108) configured to be connected to a battery (130) a receiver oscillator circuit (110) electrically coupled to the set of battery charging terminals (108), the receiver oscillator circuit including a receiver coil (112) wherein 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 a 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 (108).</p>
