Abstract

PURPOSE:To magnify the sound image to the outside of the speaker and thus to increase the ambience by supplying the addition output of the right and left stereo signals to each speaker via the sound quality correcting equalizer. CONSTITUTION:Signals L2 and R2 branched from signals L and R receive prescribed attenuation quantity A through attenuator 1 to be supplied to phase shifter 2. And signals L2 and R2 are added 3 to signals R1 and L1 respectively after receiving fixed phase shift amount theta. Each addition output is supplied to stereo speaker 5 via sound quality correcting equalizer 9. In this case, if the control is given to quantity A to 6-8dB and amount theta to 180 deg. each, the sound image extending outside the speaker becomes maximum. At the same time, the natural ambience can be obtained.
