First Claim
Patent Images
1. An audio transducer apparatus comprising:
- a component having a first material; and
a heating reduction system configured to reduce induced heating in the component, where the heating reduction system comprises a member at least partially surrounding the component, where the member comprises a material which has an electrical conductivity that is higher than an electrical conductivity of the first material to thereby reduce induced heating in the component.

19. An apparatus comprising:
-
a housing; a rechargeable battery in the housing; an induction charging system in the housing coupled to the rechargeable battery; a component in the housing, where the component comprises a first material susceptible to heating by induced eddy currents from induction charging magnetic fields generated externally from the apparatus; and an eddy current heating reduction system configured to reduce induced eddy current heating in the component by the induction charging magnetic fields, where the eddy current heating reduction system comprises a member at least partially surrounding the component, where the member comprises a second material which has an electrical conductivity that is higher than an electrical conductivity of the first material, where the member is configured to allow an induced current density to be formed in the member from the induction charging magnetic fields which is higher than an induced current density formed in the component from the induction charging magnetic fields to reduce induced eddy current heating in the component by the induction charging magnetic fields. - View Dependent Claims (20)
