Abstract

PURPOSE:To obtain the feeling of spread of sound field, by giving the same effect as the movement of speaker outside the car. CONSTITUTION:The R channel signal is fed to the adder 14 via the equalizer 10 and a part is fed to the adder 15 of the L channel via the equalizer 12. On the other hand, the L channel signal is fed to the adder 15 via the equalizer 11 and a part is fed to the adder 14 via the equalizer 13. The two signals added at the adder 14 are fed to the speaker 16 via the delay circuit 9 and the amplifier 16, and the two signals added at the adder 15 are fed to the speaker 7 via the amplifier 17. Thus, the driver 5 feels as if the speaker 6, 7 were located at 0, 0'. Further, the signals of R and L channel are added at the adder 18 to obtain the two signals in opposite phase via the echo circuit 19 and phase shifter 20 and it is fed to the adder 14, 15 to obtain the feeling of distance.
