Abstract:

An accessory for use with a portable electronic device receives audio signals from the portable electronic device and broadcasts the signals to a set of wireless speakers. The accessory device includes a dock for coupling to the portable electronic device such that audio signals, a power supply signal and digital communication signals can be transferred between the accessory and the device. The accessory receives the audio signals and transmits them to the speakers via a transmitter. The accessory also provides an audio output and video output such that audio and video files can be transferred from the portable electronic device through the accessory to an external device. Preferably, an inductive charging circuit is used to charge a rechargeable power supply in the speakers when the speakers are positioned in a speaker dock on the accessory body.
