Abstract:
A sound projection apparatus for a video display device having left and right speakers, first and second ambience speakers, and an amplifier having a right channel and left channel. In this system, connection of the left channel to a speaker produces a left signal; the right channel to a speaker produces a right signal; the left and right channels to ambience circuitry produces an ambience channel; the ambience channel to the positive input of the first ambience speaker produces a first ambience signal and the ambience channel to the negative input of the second ambience speaker produces a second ambience signal. The left and right speakers are forward facing, projecting sound directly from the television to a viewer. The first and second ambience speakers are side or rearward facing, projecting sound indirectly to the viewer. The projection apparatus may be formed as a single cohesive unit, within or near the television.
