Abstract

PURPOSE:To improve a sense of expansion of a reproducing sound field, by placing an auxiliary loudspeaker to which a prescribed signal is applied, on the outside of reproducing loudspeakers of left and right channel signals. CONSTITUTION:Signals of left and right channels are inputted from terminals 1, 2 and are applied to adders K2, K3 through an adder K1 and an HPF H. The left channel signal is applied to a left channel reproducing loudspeaker S2, and also is supplied to an auxiliary loudspeaker S1 placed on the left side of the loudspeaker S2, through the adder K2 and a delaying circuit D1. As to a right channel reproducing loudspeaker S3 and an auxiliary loudspeaker S4, too, the same signal is applied.
