PURPOSE:To make a speaker unnecessary which is exclusively used for negating crosstalk between both ears by inverting the phase of an L signal, mixing the inverted phase of the L signal to an R signal, inverting the phase of the R signal, and mixing the inverted phase of the R signal to the L signal. CONSTITUTION:The L signal, in which 'the R signal passed through a phase inverting circuit 5' is mixed at a mixing circuit 6, is sent to a left speaker 8, and the R signal, in which 'the L signal passed through a phase inverting circuit 4' is mixed at a mixing circuit 7, is sent to a right speaker 9. Thus, the speaker exclusively used for negating the crosstalk between both ears becomes unnecessary. Further, a reproduced image in response to the position of a sound source at the time of its sound recording cm be obtained by composing an electric circuit at an arbitrary position in a process from the sound recording to the reproducing. |
