Claim Text:
1. An audio transducer apparatus comprising: a magnet assembly comprising at least two magnet assembly components, where a first one of the components has a first material, where the magnet assembly is part of the audio transducer apparatus; a heating reduction system configured to reduce induced heating in the first component, where the heating reduction system comprises a member at least partially surrounding the magnet assembly, 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 first component by a field from outside the magnet assembly; and a heat transfer member extending from the member of the heating reduction system, where the heat transfer member is configured to transfer heat away from the member of the heating reduction system, where the heat transfer member comprises a ground plane of a printed wiring board of an apparatus.
