Abstract
An audio surround-sound system includes a main enclosure, an audio decoder device to decode audio source signals supplied by an audio source device to provide decoded audio signals, and at least a first and second low distortion amplifier housed within the main enclosure to receive and amplify the decoded audio signals. Also included is at least a first and a second speaker element operatively coupled to the at least first and second amplifiers, respectively, to produce the audible signals, where the audible signals are received by the listener from a first and second direction. A local radio transmitter converts a portion of the decoded audio signals into radio modulated signals and transmits the radio modulated signals where a wireless receiver receives and converts the radio modulated signals into remote audio source signals. A third speaker element produces audible signals to be received by the listener from a third direction, where the third speaker element is operatively coupled to a third low distortion amplifier. The third low distortion amplifier receives and amplifies the remote audio source signals, where the third low distortion amplifier, the wireless receiver and the …
