ABSTRACT:
A system for reproducing stereophonic signal to create a stereophonic sound image in front of each of listeners sitting side by side in a compartment. The system includes a first loudspeaker positioned relative to the right of the first listener sitting on the right, a second side loudspeaker positioned relative to the left of the second listener sitting on the left, and a center loudspeaker unit positioned between the first and second side loudspeakers. A signal generator generates R and L stereophonic signals. The R signal is applied to drive the first side loudspeaker and the L signal is applied to drive the second side loudspeaker. The R and L signals are applied to drive the center loudspeaker unit. The signal generator includes a device for providing a predetermined time delay to the R and L signals applied to drive the center loudspeaker unit with respect to the signals applied to drive the first and second side loudspeakers.
