Abstract

PURPOSE:To generate an indirect sound which is very close to natural one, by mixing the outputs of premary reflected-sound generating circuits which give directivity and an echo-sound generating circuit which gives no directivity with an electric signal which contains no indirect-sound component. CONSTITUTION:An electric signal which contains no indirect-sound components is branched into several components, which are inputted to primary reflected-sound generating circuits (a)-(m) each consisting of a volume control 13 for setting the relative level of each branched electric signal component, a front-and-back discriminating circuit 11 for giving directivity to each branched electric signal component, and a both-ear-difference producing circuit 12 and an echo-sound generating circuit R having a phase inverter 16. Then the electric signal which contains no indirect- sound components, primary reflected-sound signals from the primary reflected-sound generating circuits (a)-(m), and an echo signal from the echo-signal generating sircuit R are mixed together by mixers 8 and 8'.
