본 고안은 오디오 기기에서 사용될 수 있는 고출력 초저음 증가회로에 관한 것이다.The present invention relates to a high output ultra low amplification circuit that can be used in audio equipment.

저음을 높여서 즐기고 싶을때 종래에는 음을 자유롭게 선택할 수 있는 그래픽 이퀄라이저 기능을 메인 앰프의 전단에 두어 저음을 선택할 경우에 그래픽 이퀄라이저 앰프에 의해 다이나믹한 주파수 대역내의 선택된 저음만을 수 dB정도 높게 하여 메인 앰프에 입력시키고 입력된 저음을 하나의 메인 앰프로 증폭시켜 단일로 스피커로 출력하도록 하고 있기 때문에 메인앰프에서 출력된 저음은 중음의 스피커로 인하여 순수한 저음을 즐길 수 없을 뿐만 아니라 중, 고음이 저음보다 dB출력이 낮아질 것처럼 들리므로 원음의 풍부한 효과를 기대할 수가 없는 것이었다.When you want to enjoy the bass boost, conventionally, the graphic equalizer function that can freely select the sound is placed in front of the main amplifier, and when the bass is selected, only the selected bass in the dynamic frequency band is raised by a few dB by the graphic equalizer amplifier and input to the main amplifier. Since the bass output from the main amplifier is not able to enjoy pure bass due to the mid-speaker, the bass output from the main amplifier can be amplified by dB than the bass. Sounds like it would be low, you can not expect the rich effect of the original sound.

본 고안은 이와같은 점을 감안하여 저음의 주파수 성분의 출력을 별도로 인출시켜 증폭하고자 하는 것으로 중, 고음은 필터를 통하여 바이패스되게 하고 순수한 초저음 주파수만을 저음의 공진 회로로 부터 얻어낸후 저음 증폭회로를 통하여 수십 dB정도 증폭하고 증폭된 고출력 초저음 주파수를 초저음 전용의 스피커로 출력되게 함으로써 저음의 원음을 손실없이 재현시킬 수 있도록 한 것이다.The present invention intends to amplify the output of the low frequency components by taking into consideration the above points, and the high frequency is bypassed through the filter, and only the pure low frequency frequency is obtained from the low frequency resonance circuit. By amplifying several tens of dB and outputting the amplified high-powered ultra-low frequency to the speaker for ultra-low sound, it is possible to reproduce the original sound of low sound without loss.

이를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

메인 시그널이 공급되는 입력단자(L)(R)가 저항(R1)(R2)를 통하여 커플링 콘덴서(C1)와 연결되어 저항(R3)(R4) 및 콘덴서(C3)(C4)로 구성되는 고역 차단필터(5)와 연결되게 구성시킨다.The input terminal (L) (R) to which the main signal is supplied is connected to the coupling capacitor (C 1 ) through the resistors (R 1 ) (R 2 ), so that the resistors (R 3 ) (R 4 ) and the capacitor (C 3 ) It is configured to be connected to the high-pass cut filter (5) consisting of (C 4 ).

그리고 저항(R5-R8), 콘덴서(C2)(C7) 및 가변저항(VR)이 트랜지스터(Q1)와 연결되게 저음 증폭회로(10)를 구성하여 고역차단필터(5)가 트랜지스터(Q1)의 베이스측과 접속되게 구성하고 가변저항(VR) 및 커플링 콘덴서(C8)와 연결되는 파워 앰프(IC)와 접속되게 구성시킨후 절환스위치(SW)를 통하여 파워 앰프(IC)에 전원(Vcc2)이 공급되게 구성하고 메인 앰프(IC)의 출력측에서 콘덴서(C9)(C10)를 통하여 초저음 전용 스피커(SPL)(SPR)와 연결되게 구성한 것이다.In addition, the high-frequency cut-off filter 5 is configured by configuring the bass amplifier circuit 10 so that the resistors R 5 -R 8 , the capacitors C 2 , C 7 , and the variable resistor VR are connected to the transistor Q 1 . It is configured to be connected to the base side of the transistor (Q 1 ) and to be connected to the power amplifier (IC) connected to the variable resistor (VR) and the coupling capacitor (C 8 ), and then through the switching switch (SW) The power supply Vcc 2 is configured to be supplied to the IC, and the condenser C 9 (C 10 ) is connected to the ultra-low speaker (SPL) (SPR) at the output side of the main amplifier (IC).

여기서 콘덴서(C11)(C12)는 전원 필터용 콘덴서이다.Here, the capacitors C 11 and C 12 are capacitors for the power filter.

이와같이 구성된 본 고안에서 회로를 동작시키기 위하여는 트랜지스터(Q1) 및 파워 앰프(IC)에 전원을 공급시켜 주어야 하는데 트랜지스터(Q1)에는 전원(Vcc1)이 저항(R8)을 통하여 콜렉터측에 가해지는 동시에 저항(R5)으로 바이어스된 전압이 트랜지스터(Q1)의 베이스측에 인가되어 트랜지스터(Q1)는 턴온 상태를 유지하게 되고 파워 앰프(IC)에는 절환 스위치(SW) 접속시 전원(Vcc2)이 파워앰프에 공급되는 동작 상태가 된다.Thus configured to operate the circuit in the present design is a transistor (Q 1) and to give to supply power to the power amplifier (IC) transistor (Q 1), the power supply (Vcc 1) the resistance (R 8) a through collector side At the same time applied to the resistor (R 5) is applied to the base side of the voltage of the transistors (Q 1) biasing the transistor (Q 1) is to keep the turn-on state power amplifiers (IC), the change-over switch (SW) for connecting The power source Vcc 2 is brought into an operating state in which the power amplifier is supplied.

이와같은 상태에서 라디오 방송이나 기타 테이프의 재생음이 메인 시그널 입력단자(L)(R)로 입력되면 저항(R1)(R2)을 통하여 입력되는 시그널 중에 커플링 콘덴서(C1)에 의하여 직류 성분은 차단된후 저항(R3)(R4) 및 콘덴서(C3)(C4)로 구성되는 고역 차단필터(5)에 의하여 고역이 감쇄되는 동시에 고역의 주파수 성분은 바이패스된다. 즉 저항(R3)(R4) 및 콘덴서(C3)(C4)는 특정된 저역 주파수 대역에서 공진되므로 저역 주파수 신호의 성분만이 트랜지스터(Q1)의 베이스측에 공급된다.In such a state, when the sound of a radio broadcast or other tape is input to the main signal input terminal (L) (R), a direct current is generated by the coupling capacitor (C 1 ) among the signals input through the resistor (R 1 ) (R 2 ). After the components are cut off, the high band is attenuated by the high pass filter 5 composed of the resistors R 3 and R 4 and the capacitors C 3 and C 4 , and the high frequency components are bypassed. That is, since the resistors R 3 (R 4 ) and the capacitors C 3 (C 4 ) resonate in the specified low frequency band, only the components of the low frequency signal are supplied to the base side of the transistor Q 1 .

저음 증폭회로(10)의 트랜지스터(Q1)에 의하여 증폭된 저역 주파수는 콜렉터측으로 출력될때에 출력저항(R7)에 의하여 강하되는 동시에 (안정됨) 저역 주파수 대역에 포함되어 있는 직류 성분은 커플링 콘덴서(C7)에 의하여 저지된다.The low frequency amplified by the transistor Q 1 of the bass amplification circuit 10 is dropped by the output resistor R 7 when output to the collector side, and the DC component included in the low frequency band (stable) is coupled. This is prevented by the capacitor C 7 .

이때 출력되는 저역 주파수 전압은 수 mV정도로 미약하므로 가변저항(VR)를 통하여 파워앰프(IC)에 입력되어 저역주파수를 수 V정도로 증폭시켜 출력된다.At this time, the output low frequency voltage is weak to about a few mV is input to the power amplifier (IC) through the variable resistor (VR) to amplify the low frequency to several V is output.

이렇게 출력된 저역 주파수는 각각 커플링 콘덴서(C9)(C10)를 통하여 저음 전용의 고출력 스피커(SPL)(SPR)로 출력되는 것으로 음량 조절용 가변저항(VR)에 의하여 원하는 크기로 저역을 청취할 수가 있는 것이다.The low frequencies thus output are output to high-power speakers (SPL) (SPR) dedicated to low sound through coupling capacitors (C 9 ) and (C 10 ), respectively. You can do it.

이상에서와 같은 본 고안은 메인 앰프에 공급되는 시그널에서 고역 성분을 차단시킨후 초저음 신호만을 증폭시켜 별도의 스피커로 출력되게 함으로서 저음의 원음을 손실없이 그대로 재생시킬 수가 있어 오디오 기기의 효능을 증대시킬 수 있는 효과가 있는 것이다.As described above, the present invention cuts the high frequency component from the signal supplied to the main amplifier and then amplifies only the ultra bass signal to be output to a separate speaker so that the original sound of the bass can be reproduced without loss, thereby increasing the effectiveness of the audio device. There is an effect that can be made.
