Abstract
An inductively enabled audio speaker is disclosed configured to receive power inductively from an inductive power outlet. The audio speaker device has a voice coil which, as well as being able to produce an audible output, is further configured to function as a secondary inductor to inductively couple with a primary inductor. The inductively enabled audio speaker may be used to power an electrical device such as a Bluetooth earpiece, a telephone or the like.
