Abstract
PURPOSE:To increase the sound field at a narrow place by applying the stereo signal of one side to that of the other side in the opposite phase to each other and setting the hearing state for both the right and left speakers to the state under which the speaker is installed outside. CONSTITUTION:The right and left stereo signals applied to input terminals 10 and 11 are applied to adders 12 and 13, and the signals sent from terminal 11 are given the opposite phase via phase shifter 14 to be applied to adder 12. Furthermore, the right and left stereo signals are added together at adder 20, and indirect tone signal delayed at delay circuit 21 is applied to adder 12. And the indirect tone signal which is phase-reversed via phase shifter 22 is applied to adder 13. The output of adder 12 is applied to speaker 18 via amplifier 15, and the output of adder 13 is applied to speaker 19 via delay circuit 17 and amplifier 16. And the sound sent from speakers 18 and 19 is taken outside the place where speakers 18 and 19 are located. As a result, the sound field can be increased even at a narrow place.
