Abstract
PURPOSE:To facilitate the integration of an acoustic signal regenerating circuit through simplifying the constitution of a delay circuit by connecting a signal generating circuit in front of the delay circuit and a phase-inverted signal generating circuit behind the delay circuit. CONSTITUTION:A left signal L and right signal R applied to input terminals 1 and 2 are applied to signal transmission systems 3 and 4 and also inputted to a difference signal generating circuit 15, which generates a difference signal L-R. This difference signal, after being delayed by a certain delay time by a delaying circuit 15, is applied to a phase-inverted signal generating circuit 17, which outputs phase difference signals 18 and 19 of an antiphase. Those difference signals 18 and 19 are a K(L-R)m and K(R-L)m (where K is a constant and m is the delay time), and added to the outputs of the transmission systems 3 and 4 respectively. Then, the addition outputs are represented as a L+K(L-R)m and R+K(R-L)m and, after being amplified by amplifiers 11 and 12, applied to speakers 13 and 14, thus facilitating integration by simplifying the constitution of the delay circuit 16.
