Stereophonic effect speaker arrangement
First Claim
1. A loudspeaker arrangement for reproducing acoustic events, carried on at least two channels, in a room with at least two sidewalls, comprising a housing at least one first sound-radiating transducer positioned in said housing to radiate sound directly toward a listener, at least two second sound transducers, positioned in said housing for radiating sounds toward the at least two sidewalls, respectively, and means connected to said first and second transducers for supplying the acoustic events carried on said channels to said first and second transducers with one of said channels supplied to one of said second transducers, another of said channels supplied to the other of said second transducers and said another of said channels supplied to said first transducer, whereby, sound from said second transducers reach the listener with a delay with respect to sound reaching the listener from said first transducer.

Abstract
A device for reproducing acoustic events carried on at least two channels, in a room with at least two sidewalls, comprising, at least one first sound-radiating transducer positioned to radiate sound toward a listener with at least two second sound-radiating transducers positioned in association with the first sound-radiating transducer and for radiating sound toward the at least two sidewalls, respectively. The two channels carrying the acoustic event are supplied to the first and second transducers so that the first transducer receives both channels and each of the second transducers receives one of the two channels. The listener thus receives sound waves from the two second transducers with delay. A delay device may also be connected to the two second sound transducers for producing an additional delay in the first and second channels supplied thereto.

3. A loudspeaker arrangement for reproducing acoustic events of the type transmitted through at least two channels in a room having sound reflecting sidewalls comprising a housing;
- loudspeaker means mounted in said housing for radiating sound from said housing in at least two directions;
said loudspeaker means having at least one loudspeaker for each channel transmitting the acoustic events to be reproduced and for reproducing middle and high range frequencies in the acoustic events to be reproduced being positioned to laterally radiate sound toward one of the sidewalls to cause the sound to be reflected off the sidewall and delay its reaching a listener in the room, and a loudspeaker positioned to radiate sound forwardly;
means for controlling the amplitude or frequency response of the loudspeaker of each channel; and
delay means operative for delaying the sound radiated from each loudspeaker positioned to laterally radiate sound with respect to sound radiating from said loudspeaker positioned to radiate sound forwardly. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)
