이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

먼저 우측입력단자(RIN)로 1KHZ부근의 음성신호가 입력되면 입력된 1KHZ의 음성신호는 제3음성신호 증폭부(30)내의 증폭기(Amp3)의 입력비반전(=) 단자에 원래의 1KHZ부근 음성신호가 그대로는 인버어팅(Non-Inverting)되어 입력됨과 동시에 제1음성신호 증폭부(10)내의 콘덴서(C1)(C2)와 저항(R1)(R3)을 통해 증폭기 (Amp1)의 입력단자로 논 인버어팅 되어 입력된다.First, when a voice signal near 1 KH Z is input to the right input terminal R IN , the input 1 KH Z voice signal is input to an input non-inverting (=) terminal of the amplifier Amp 3 in the third voice signal amplifier 30. The original 1KH Z near voice signal is inverted and input as it is, and at the same time, the capacitor C 1 (C 2 ) and the resistor R 1 (R 3 ) in the first voice signal amplifying unit 10. Through the non-inverted input to the input terminal of the amplifier (Amp 1 ) through.

그리하여 증폭기 (Amp1)에서는 그에 입력된 1KHZ부근의 음성신호를 증폭하여 위상이 90°천이된 음성신호를 출력한다.Thus, the amplifier Amp 1 amplifies the voice signal near 1KH Z input thereto and outputs a voice signal having a phase shift of 90 °.

증폭기(Amp1)에서 90°위상 천이된 음성신호는 제2음성신호 증폭부(20)내의 콘덴서(C3), 저항(R7) 및 저항(R5)을 통하여 증폭기 (Amp2)의 입력단자로 논 인버어팅 되어 입력되므로 증폭기(Amp2)에서도 그에 입력된1KHZ부근의 음성신호를 증폭하여 90°위상 천이시켜서 증폭기 (Amp2)로부터 180°위상 천이된 1KHZ음성 신호가 출력되어 제4음성 신호 증폭부(40)내의 증폭기 (Amp4)의 입력비반전(=)단지로 180°위상 천이된 1KHZ의 음성신호가 출력된다.The voice signal shifted by 90 ° from the amplifier Amp 1 is input to the amplifier Amp 2 through the capacitor C 3 , the resistor R 7 , and the resistor R 5 in the second voice signal amplifier 20. Since the non-inverted input is made to the terminal, the amplifier Amp 2 also amplifies the audio signal near the 1 KH Z input thereto and makes a 90 ° phase shift to output a 1KH Z voice signal 180 ° out of phase from the amplifier Amp 2 . The audio signal of 1KH Z which is 180 ° out of phase is output to the input non-inverting (=) terminal of the amplifier Amp 4 in the 4-audio signal amplifier 40.

이와같은 상태에서 바이호닉 온/오프 선택 스위치(Sw)에 의하여 증폭기(Amp3)의 입력비반전(+)단자에 입력된 원래의 1KHZ부근의 음성신호나 증폭기(Amp4)의 입력비반전(+)단자로 180°위상 천이된 1KHZ부근의 음성신호가 우측 출력단자(Rout)로 출력되게 되는데 어느 것을 출력할 석인가에 대하여는 음성신호 선택부(50)내의 바이호닉 온/오프 선택 스위치(Sw)에 의해 출력된다.In this state, the audio signal near the original 1KH Z input to the input non-inverting (+) terminal of the amplifier Amp 3 by the bihonic on / off selection switch Sw or the input non-inverting of the amplifier Amp 4 . The audio signal near 1KH Z , which has a 180 ° phase shift to the (+) terminal, is output to the right output terminal (Rout). The bihonic on / off selection switch in the audio signal selector 50 determines which stone is to be output. It is output by (Sw).

즉, 바이호닉 온/오프 선택스위치(Sw)를 "온"으로 선택하면 "온"된 스위치(Sw)와 저항(R17)을 통하여 트랜지스터(Q1)의 베이스에 "H"펄스가 입력되면 트랜지스터(Q1)가 새튜레이션(Saturation)되어 우측 출력단자(Rout)로 증폭기 (Amp3)에 입력된 원래의 1KHZ부근의 음성신호가 출력되고, 바이호닉 온/오프 선택스위치(Sw)를 "오프"로 선택하면 , 오프된 스위치(Sw)를 통하여 트랜지스터(Q1)에 베이스에 "L"펄스가 입력되면 트랜지스터(Q1)가 카트오프(CUT OFF)되어 증폭기 (Amp4)에 입력된 180°위상 천이된 1KHZ부근의 음성신호가 우측 출력단자(Rout)로 출력되는 것이다.That is, when the bi-honic on / off selection switch Sw is selected as “on”, when the “H” pulse is input to the base of the transistor Q 1 through the “on” switch Sw and the resistor R 17 . Transistor Q 1 is saturated to output the audio signal near the original 1KH Z input to amplifier Amp 3 through the right output terminal R out , and the bihonic on / off selection switch Sw. Is selected as "OFF", when the "L" pulse is input to the transistor Q 1 through the switch Sw that is turned off, the transistor Q 1 is cut off to the amplifier Amp 4 . The audio signal near the input 180 ° phase shifted 1KH Z is output to the right output terminal R out .

이와 같이 본 고안은 극히 간결한 경제적인 구조로써 1KHZ부근에서 입력된 R측의 음성신호를 180°위상 천이시켜 주므로써 Rout단자로 180°위상 천이된 1KHZ부근의 음성신호가 출력되어 보다더 실장감 있고 웅장한 에코우 효과를 얻을 수가 있는 것이다.As such, the present invention is an extremely simple and economical structure, whereby the audio signal of the R side input near 1KH Z is shifted 180 ° out of phase, so that the audio signal near 1KH Z that is 180 ° out of phase is output to the R out terminal. It has a realistic and magnificent echo effect.
