Headset unit
A headset unit for interfacing user-supplied communications and audio player devices with a speaker or headphones. The headset unit includes a cradle having a first area for releasably holding the communications device and a second area for releasably holding the audio player. The cradle includes circuitry for electrically connecting the audio outlets of the telephone and audio player with a cradle audio outlet which may then be connected to headphones. Additional circuitry provides a plurality of audio control modes selectable by a user. Specifically, audio signals may be selectively received by the cradle audio outlet only from the telephone, only from the audio player, from both simultaneously, or only from the telephone during a call. A rechargeable power source is attached to the cradle for selectively recharging the telephone or audio player.
