Abstract
PURPOSE:To expand the reproduced sound image by changing over the switch between the input terminal and the arithmetic circuit and the switch to vary the delay time in accordance with the monaural and stereo reproduction. CONSTITUTION:The monaural signals or the right-left stereo signals sent from input terminals 1 and 1' are supplied to subtractor 2, and the difference signal calculated through subtractor 2 is applied to delay element 5 via filter 5. This difference signal is then applied to adders 12 and 14 in the form of the opposite phase signal via filter 10 and amplifier 11 and then compounded with the monaural or stereo signals given from terminals 1 and 1' to deliver the aural signals through speakers 17 and 18. Then switch 3 is provided between subtractor 2 of such constitution and input terminal 1, along with change-over switch 9 which switches the delay time of delay element 5 and controls the output of clock generator 6. These switches 3 and 9 are switched according to the monaural or stereo reproduction time, thus expanding the width of the reproduced sound to reach the ears of the listeners.
