In-Home Theater Surround Sound Speaker System
US Patent:
5930370, Jul 27, 1999
Filed:
Sep 3, 1996
Appl. No.:
8/707101
Inventors:
Jerome E. Ruzicka - Stow MA
Assignee:
REP Investment Limited Liability - Grand Rapids MI
International Classification:
H04R 500
US Classification:
381 18
Abstract:
An apparatus for realistically reproducing sound, particularly for sound based on a stereophonic signal having dialog and effects and associated with an accompanying video image. The apparatus includes a front speaker 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 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. Left and right speakers located to the respective left and right sides of the viewing area. The left and right channels speakers reproduce in one embodiment the respective left and right channels of the audio signal and in a second embodiment reproduce a difference signal, (L-. beta. R) or (R-. beta. L), where. beta. is a gain which may vary or may be a value fixed between zero and unity.
Surround Sound Speaker System For Improved Spatial Effects
US Patent:
6118876, Sep 12, 2000
Filed:
Mar 19, 1998
Appl. No.:
9/044620
Inventors:
Jerome E. Ruzicka - Stow MA
Assignee:
REP Investment Limited Liability Company - Muskegon MN
International Classification:
H04R 500
US Classification:
381 18
Abstract:
An apparatus for realistically reproducing sound, particularly for sound based on a stereophonic signal having dialog and effects and associated with an accompanying video image. The apparatus includes a front speaker 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 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 are located to the respective left and right sides of the viewing area. The left side speaker provides two acoustic outputs in accordance with a band limited left channel signal and a band limited difference signal. The right side speaker 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.
