Abstract
A universal four-channel multimedia computer speaker system is connectable to audio sub-system control circuits (e.g., “sound cards”) of both the four-channel type and the conventional two-channel (stereo) type. With the audio sub-system control circuit being of a four-channel type, the universal four-channel audio system functions as a conventional multimedia computer four-channel surround sound audio system. With a four audio channel multimedia computer work and the audio sub-system control circuit being of a conventional two-channel (stereo) type, the universal four-channel audio system is configured to provide one pair of wide-band speakers (e.g., the front) with distinct audio playback according to respective right-front and left-front audio channels in a four or two audio channel multimedia computer work such as a game, music, etc. The universal four-channel audio system is configured to provide at the rear speakers distinct audio playback that are generated from the right-front and left-front audio channels in the four or two audio channel multimedia computer work.
