Abstract
PURPOSE:To improve the stereo effect, by supplying a false stereo signal to an orientation information adding circuit and by orientating it outside the extension range of the actual speaker. CONSTITUTION:The monaural signal input from terminal 1 is taken out as inphase and antiphase signals through monaural signal-false stereo signal converting circuit 6. These signals are input to orientation information adding circuit 7, and the ratio of transmission functions Ai and Bi is set to the differential characteristic between both ears to extend the spread of the acoustic image dependent upon a virtual speaker. Reproducing speaker cancelling circuit 8 sets the ratio of transfer functions A and B to the differential characteristic between both ears and prevents the reproducing sound from being mixed with the sound from the virtual speaker. Consequently, the virtual speaker is orientated outside the extension range of the actual speaker, so that a sufficient stereo effect can be obtained even if two speaker places are narrow.
