An apparatus and method for powering headphone electronics over a standard audio signal cable without interfering with the normal audio transmission or playback of transmitted audio signals. A software application resides on a cell/smart phone or other mobile device that combines the nominal audio output of such a mobile device, like music or spoken word, with a high frequency audio signal to produce a dual component signal. The high frequency component is decoded and rectified outside of the mobile device, either in a connector or on the structure of the headphones themselves, to produce a direct current ('DC') that powers the headphones. The music or other audible signal component transferred over the audio cable is decoded in parallel and sent to the headphone speakers for normal playback. The invention provides an alternative power source to headphone electronics such as active noise cancelling headphones over the audio cable.

Headphone power system using high frequency signal conversion

A computing device comprises a platform and an audio receiver component. The audio receiver component is provided on a front side of the platform and is oriented to emit sound out of the front of the housing. A gap volume adjacent to the audio receiver is defined by the front side of the platform and the front fa&#xe7;ade of the housing. The gap volume supports audio output from the audio receiver component. A first air channel is defined by a combination of (i) a through-hole in the platform at the gap volume, and (ii) an opening in a back fa&#xe7;ade of the housing.
