본 고안은 더블데크를 구비하고 있는 음향기기의 더빙기능을 제어하는 음향기기의 더빙기능제어회로에 관한 것이다.The present invention relates to a dubbing function control circuit of an acoustic device for controlling the dubbing function of an acoustic device having a double deck.
근래에 보급되고 있는 통칭 더블데크카셋트라고 불리워지는 음향기기에는 복사기능이 갖추어져 있는데 이는 하나의 데크로부터 재생되는 음성신호를 다른 데크에 재녹음시켜 복사하는 기능을 뜻하는 것으로서 이러한 기능은 더빙(dubbing)이라고도 불리워지는 바, 이에 대해 종래의 더빙기능제어회로는 다단의 스위칭 소자를 사용하도록 되어있기 때문에 그 회로구조가 복잡해지고 회로규모가 커지게 된다고 하는 단점을 가지고 있었다.A sound device, commonly known as a double deck cassette, is equipped with a copy function, which means that a sound signal reproduced from one deck is copied to another deck and duped. It is also called, the conventional dubbing function control circuit has a disadvantage in that the circuit structure is complicated and the circuit size becomes large because it is to use a multi-stage switching element.
본 고안은 상기와 같은 더빙기능을 갖는 음향기기의 더빙제어회로를 개선시킨 것으로, 간단한 구조의 스위칭회로로써 더빙기능 및 기타 모우드 절환기능을 충실하게 수행할 수 있도록 된 음향기기의 더빙기능 제어회로를 제공하고자 함에 그 목적이 있다.The present invention is an improvement of a dubbing control circuit of an audio device having a dubbing function as described above, and a dubbing function control circuit of an audio device capable of faithfully performing a dubbing function and other mode switching functions as a switching circuit of a simple structure. The purpose is to provide.
이하 본 고안으 구성 및 작용, 효과를 예시도면에 의거 상세히 설명한다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail based on the drawings.
본 고안은 기능선택스위치(FN SW)와 매인앰프(1)의 B+전원출력단(B+OUT)과의 사이에 저항(R5∼R7)(Rc)과 콘덴서(C7), 트랜지스터(Q1)(Q2), 다이오드(D5∼D8), 더빙표시등(LED1), 재생데크(2)의 모우드절환스위치(MS1) 및 녹음/재생데크(3)의 모우드 절환스위치(MS2)등이 구비된 스위칭회로(4)가 연결되고, 매인앰프(1)의 B+전원출력단(B+OUT)의 일단에는 저항(R8∼R11)과 스위치(SW1)(SW2)·트랜지스터(Q3∼Q5) 및 모우터(M1)(M2)가 구비되어 있는 데크구동모우터(M1)(M2)의 제어회로(5)가 연결, 구조로 되어있다.The present invention provides a resistor (R 5 to R 7 ) (Rc), a capacitor (C 7 ), and a transistor (B) between the function selection switch (FN SW) and the B + power output terminal (B + OUT) of the main amplifier (1). Q 1 ) (Q 2 ), diode (D 5 ~ D 8 ), dubbing indicator (LED 1 ), mode changeover switch (MS 1 ) of playback deck (2) and mode changeover switch of recording / playback deck (3) (MS 2 ) is provided with a switching circuit (4) is connected, the resistor (R 8 ~ R 11 ) and the switch (SW 1 ) ( one end of the B + power output terminal (B + OUT) of the main amplifier ( 1 ) ( SW 2) · transistor (Q 3 ~Q 5) and Motor (M 1) (M 2) the deck is provided with driving Motor (M 1) (M 2), the control circuit 5 is connected in, the structure It is.
미설명부호 6은 포노회로이고, 7은 튜너회로 8은 마이크입력회로, 9는 AC바이어스회로, 10은 스피이커를 각각 나타낸다.Reference numeral 6 denotes a phono circuit, 7 a tuner circuit 8 a microphone input circuit, 9 an AC bias circuit, and 10 a speaker.
제1도는 상기아 같이 구성된 본 고안의 구체적인 회로도로써, 우선 더빙기능이실시되지 않고 기타기능인 포노모우드나 튜너모우드가 기능선택스위치(FN SW)에 의해 선택되게 되면, 매인앰프(1)의 B+전원이 기능선택스위치(FN SW)를 통해 포노회로(6)나 튜너회로(7)의 B+전원입력단(B+IN)에 인가되므로 각 회로로는 해당되는 기능을 수행하게 되는 바, 즉, 기능선택스위치(FN SW)에 의해 포노모우드가 선택때 된에는 B+전원이 다이오드(D10)와 스위칭회로(4)의 저항(R5)을 통해 트랜지스터(Q1)의 베이스로 인가되므로 트랜지스터(Q1)가 턴온되게 되고, 그에 따라 트랜지스터(Q1)의 컬렉터전위가 접지전위로 떨어지게 되므로 재생데크(2)와 녹음/재생데크(3)의 출력단(OUT)에서 출력되는 음성신호가 다이오드(D1)를 통해 매인앰프(1)측으로 가해지지 않고, 스위칭회로(4)의 콘덴서(C7)와 트랜지스터(Q1)를 통해 접지로 뮤팅되게 된다. 여기서 콘덴서(C7)는 전해콘덴서를 사용하게 되므로 음성신호에 대한 임피던스가 작아서 상기 음성신호가 콘덴서(C7)를 통해 접지로 뮤팅되게 된다. 즉, 교류뮤팅회로로 동작하게 된다.1 is a detailed circuit diagram of the present invention, which is configured as described above. First, when the dubbing function is not performed and other functions, such as phono mode or tuner mode, are selected by the function selection switch (FN SW), B + of the main amplifier 1 Since power is applied to the B + power input terminal (B + IN) of the phono circuit 6 or the tuner circuit 7 through the function selection switch (FN SW), that is, to perform the corresponding function in each circuit, that is, When the phono mode is selected by the function selection switch (FN SW), B + power is applied to the base of the transistor (Q 1 ) through the diode (D 10 ) and the resistor (R 5 ) of the switching circuit (4). Since (Q 1 ) is turned on, the collector potential of transistor (Q 1 ) falls to the ground potential, so that the audio signal output from the output deck (OUT) of the playback deck (2) and the recording / playback deck (3) is diode. without being applied toward the bound amplifier (1) through (D 1), the switch Muting is presented to the ground through a capacitor (C 7) and the transistor (Q 1) of the circuit (4). Since the capacitor C 7 uses an electrolytic capacitor, the impedance of the voice signal is small so that the voice signal is muted to the ground through the capacitor C 7 . That is, it operates as an AC muting circuit.
또한 기능선택스위치(FNSW)에 의해 튜너모우드가 선택된 경우에도 B+전원이 다이오드(D9)와 스위칭회로(4)의 저항(R5)을 통해서 트랜지스터(Q1)의 베이스로 인가되므로 트랜지스터(Q1)가 턴온되게 되고 그에 따라 이때에도 상기한포 노모우드가 선택된 경우와 마찬가지로 재생데크(2)와 녹음/재생데크(3)의 신호출력단(OUT)이 접지되기 때문에 양데크(2)(3)의 재생신호는 매인앰프(1)측에 가해지지 않게 된다. 그런데 여기서 상기 포노모우드나 튜너모우드선택시 재생데크(2) 및 녹음/재생데크(3)의 B+전원입력단(B+IN)에 B+전원을 인가시켜 주는 이유는 절환스위치의 수효를 절감해주기 위한 것으로서, 재생데크(2) 및 녹음/재생데크(3)의 B+전원입력단(B+IN)으로 B+전원이 인가되어도 상기한 바와 같이 재생데크(2) 또는 녹음/재생데크(3)의 신호출력단(OUT)이 접지되어 포노나튜너의 기능에는)아무런 영향을 주지 않게 된다.In addition, even when the tuner mode is selected by the function selection switch FNSW, B + power is applied to the base of the transistor Q 1 through the diode D 9 and the resistor R 5 of the switching circuit 4. Q 1 ) is turned on and thus both decks (2) and (3) because the signal output terminal (OUT) of the play deck (2) and the recording / playback deck (3) are grounded as in the case where the Hanpo Mode is selected. ) Is not applied to the main amplifier 1 side. However, when the phono mode or tuner mode is selected, the reason why B + power is applied to the B + power input terminal (B + IN) of the playback deck (2) and the recording / playback deck (3) reduces the number of switching switches. As described above, even if B + power is applied to the B + power input terminal (B + IN) of the playback deck (2) and the recording / playback deck (3), the playback deck (2) or the recording / playback deck (3) The signal output terminal (OUT) is grounded so that it does not affect the function of the phono tuner.
이와 달리 더빙기능이 실시될 때의 동작은 다음과 같다.In contrast, the operation when the dubbing function is performed is as follows.
더빙기능이 수행되어지도록 하려면, 우성 재생데크(2)를 재생모우드로 선택하고 녹음/재생데크(3)를 녹음모우드로 선택하게 되는데, 여기서 재생데크(2)의 모우드절환스위치(MS1)는 녹음/재생데크(3)의 모우드 절환스위치(MS2)를 더빙기능을 수행하도록 녹음모우드를 선택할 때에 녹음단자(R)가 연결됨과 더불어 그에 연동으로 절환스위치(MS1)가 재생단자(P)에서 개방단자(R)로 연결되고, 기능선택스위치(FN SW)는 테이프단자(TAPE)측으로 선택되어지게 되고, 그에 따라 데크구동모우터(M1)(M2)측의 스위치(SW1)(SW2)도 함께 ON상태로 된다.In order to perform the dubbing function, the dominant playback deck 2 is selected as the playback mode, and the recording / playback deck 3 is selected as the recording mode, where the mode switching switch MS 1 of the playback deck 2 is When the recording mode is selected to dub the mode switching switch (MS 2 ) of the recording / playback deck (3), the recording terminal (R) is connected and the switching switch (MS 1 ) is connected to the playback terminal (P). Connected to the open terminal (R), the function selection switch (FN SW) is selected to the tape terminal (TAPE) side, accordingly the switch (SW 1 ) of the deck drive motor (M 1 ) (M 2 ) side (SW 2 ) is also turned on.
그러면, 제어회로(5)의 상측에 있는 구동모우터(M1)(M2)에 전원이 인가되어 테이프틸을 구동시켜주는 모우터(M1)(M2)가 회전하게 되고, 스위치(SW1)(SW2)가 온됨에 따라 제어회로(5)에 있는 트랜지스터(Q3)(Q4)가 턴-온 되므로 트랜지스터(Q5)도 역시 턴-온되게 된다.Then, the drive Motor (M 1) Motor (M 1), which was applied with a power supply is driving the tape teal to (M 2) (M 2) in the upper side of the control circuit 5 is rotated, a switch ( As SW 1 ) (SW 2 ) is turned on, transistor Q 3 (Q 4 ) in control circuit 5 is turned on, so transistor Q 5 is also turned on.
따라서 다이오드(D11)를 통과하는 B+전원선( 1)이 접지상태가 되므로 마이크 입력회로(8)는 비동작상태에 놓여지게 된다. 즉, 트랜지스터(Q3-Q4)는 모우터(M1)(M2)가 모두 동작할때(더빙기능시) 내부콘덴서마이크의 녹음을 방지해 주기 위한 것으로서, 모우터(M1)가 온되고 모우터(M2)가 온되면 크랜지스터(Q3)(Q4)는 턴온되어 트랜지스터(Q5)의 베이스전압이 트랜지스터(Q5)의 에미터전압보다 낮아지게 되므로 트랜지스터(Q5)가 턴온되어 다이오드(D11)의 애노드가 로우레벨로 되고, 그에 따라 다이오드(D11)가 차단되어 마이크입력회로(8)에 B+전원이 인가되지 못하게 되므로 마이크가 구동되지 않아 마이크에 의한 녹음이 방지되게 된다.Therefore, the B + power line through the diode (D 11 ) The microphone input circuit 8 is placed in an inoperative state because 1 ) becomes a ground state. That is, transistor (Q 3 -Q 4) is Motor (M 1) (M 2) a (when dubbing function) when both operate as for a recording period by preventing the internal condenser microphone, the Motor (M 1) If on and Motor (M 2) is turned on is greater transistor (Q 3) (Q 4) is turned on becomes the base voltage of the transistor (Q 5) is lower than the emitter voltage of the transistor (Q 5), so the transistor (Q 5 ) is turned on so that the anode of the diode D 11 is at a low level. As a result, the diode D 11 is cut off so that the B + power is not applied to the microphone input circuit 8. Recording is prevented.
한편, B+전원은 전원선(ι2)을 타고 녹음/재생데크(3)의 B+전원입력단(B+IN)에 직접인가되고, 재생데크(2)의 모우드 절환스위치(MS1)가 개방됨에 따라 트랜지스터(Q2)가 턴오프되게 되어, 상기 B+전원이 저항(R7)→다이오드(D6)를 통해 재생데크(2)의 B+전원입력단(B+IN)에 가해지므로 두 데크(2)(3)는 동작을 하게 된다.On the other hand, the B + power supply is directly applied to the B + power input terminal (B + IN) of the recording / playback deck (3) by the power line (ι 2 ), the mode switching switch (MS 1 ) of the playback deck (2) is As it opens, transistor Q 2 is turned off, so that B + power is applied to B + power input terminal B + IN of regeneration deck 2 through resistor R 7 → diode D 6 . Both decks (2) (3) will operate.
이때 더빙표시등(LED1)에도 전원이 인가되어 더빙표시등(LED1)이 점등되게 되므로 외부에 더빙상태가 표시된다.At this time, since the dubbing indicator (LED 1) is applied to the power dubbing indicator (LED 1) is to be lit outside the dubbing state is displayed on.
한편 재생데크(2)에 B+전원이 인가되면, 이 전원의 일부는 저항(R1)을 통해 다이오드(D1)에 바이어스 전원으로 가해지게 되므로 다이오드(D1)가 턴-온되어 재생데크(2)에서 재생되는 신호는 콘덴서(C1)→다이오드(D1)→저항(R2)→콘덴서(C2)의 통로를 통해 녹음/재생데크(3)의 녹음신호 입력단(REC IN)에 가해진다.On the other hand, when B + power is applied to the regeneration deck 2, a part of this power is applied to the diode D 1 as a bias power supply through the resistor R 1 , so the diode D 1 is turned on and the regeneration deck is turned on. The signal reproduced in (2) is recorded signal input terminal (REC IN) of recording / playback deck (3) through the passage of condenser (C 1 ) → diode (D 1 ) → resistor (R 2 ) → condenser (C 2 ). Is applied to.
전술한 동작을 거쳐 재생데크(2)의 재생신호가 녹음/재생데크(3)에 인가되어 녹음되므로 복사기능인 더빙이 신시되는 것이다.Through the above-described operation, the reproduction signal of the reproduction deck 2 is applied to the recording / reproduction deck 3 to be recorded so that dubbing, which is a copy function, is reproduced.
상기한 바와같이, 본 고안은 비교적 간단한 회로구성으로서 더빙기능을 제어할 수 있게 되므로서, 제품의 소형화의 제품원가의 절감에 기여할 수 있는 장점을 가지고 있다.As described above, the present invention has the advantage of being able to control the dubbing function with a relatively simple circuit configuration, thereby contributing to the reduction of product cost due to the miniaturization of the product.
