IN-HOME THEATER SURROUND SOUND SPEAKER SYSTEM

摘要

An apparatus for realistically reproducing sound includes a front speaker (20) located in proximity to the video image for providing acoustic output based upon a summation signal of the component left and right (L + R) channels of the audio signal. A rear speaker (26) located to the rear of the viewing area provides acoustic output based upon a difference signal, (L - R or R - L), between the left and right channels. The left and right side speakers (22, 24) are located to the respective left and right sides of the viewing area. The left side speaker (22) provides two acoustic outputs in accordance with a band limited left channel signal and a band limited difference signal. The right side speaker (24) provides two acoustic outputs in accordance with a band limited right channel signal and a band limited difference signal. Band limiting substantially filters out frequency components below a predetermined threshold.
