본 고안은 자동응답 전화기에 있어서, 자동응답녹음기의 재생신호와 톤 링거를 통한 벨 신호를 한개의 스피커로 구동하도록 한 자동응답 전화기의 스피켜 구동회로에 대한 것이다.The present invention relates to a speech driving circuit of an answering machine for driving a reproducing signal of an answering machine and a bell signal through a tone ringer with one speaker.

종래의 자동응답 전화기는 자동응답녹음기용 스피커와 톤 링거용 스피커를 별도로 부착시켜 사용하였기 때문에 기기자체의 부피가 커지고 가격이 상승함은 물론 자동응답 녹음기용 스피커가 작동되고 있을 동안에 전화벨 신호가 입력하게 되면 톤 링거용 스피커에 구동되는 전화벨 소리는 2개의 스피커에 동시에 인가되어 잘 들리지 않게되는 폐단이 있었다.In the conventional answering machine, the speaker for the answering machine and the tone ringer are separately attached so that the volume of the device itself is increased, the price is increased, and the ringing signal is input while the speaker for the answering machine is in operation. When the ringing sound driven by the tone ringer speaker is applied to two speakers at the same time, there is a closed end.

따라서 본 고안은 상기와 같은 문제점을 개선하기 위한 것으로, 자동응답 전화기의 녹음내용이 재생되는 동안 즉 자동응답 녹음기용 스피커가 구동되는 동안에 벨 신호가 입력하게 되면 상기의 자동응답 녹음기회로를 오프시켜주는 반면에 벨 신호를 톤링거회로를 통해 동일한 스피커에서 연결시켜주므로서, 전화벨 소리를 사용자가 명확하게 들을 수 있음은 물론 1개의 스피커만을 사용하도록 하였기 때문에 제품의 크기가 소형화되고 가격이 절감되는 것으로 이를 첨부도면에 의해 상술하면 다음과 같다.Therefore, the present invention is to improve the above problems, and when the bell signal is input while the recording of the answering machine is playing, that is, while the speaker for the answering machine is being driven, the answering machine circuit is turned off. On the other hand, by connecting the bell signal to the same speaker through the tone ringer circuit, the user can clearly hear the telephone ringing sound and use only one speaker, which reduces the size of the product and reduces the cost. When described in detail by the accompanying drawings as follows.

제1도는 본 고안의 블록다이어그램으로서, 자동응답 전화기의 테이프 레코오더에 녹음된 내용을 재생할때, 단자(y)(y')로 밸신호가 입력되지 않으면, 신호검출회로부(3)에 의해 스위칭회로부(2)는 '온'되고 스위칭회로부(2')는 '오프'되어 상기 테이프 레코오더의 녹음내용이 통상의 앰프회로부(1)에서 증폭되어 스위칭회로부(2)를 통해 스피커(SP)를 구동시키는 것이며, 한편 테이프 레코오더의 녹음내용의 재생도중에 단자(y)(y')로 벨신호가 입력되면 신호검출회로부(3)에 의해 스위칭회로부(2)는 '오프'되고 스위칭회로부(2')는 '온'되어 앰프회로부(1)의 출력이 스위칭회로부(2)에서 차단됨과 동시에 입력된 벨신호가 통로의 톤링거회로부(4)에서 발진된후 스상위칭회로부(2')를 통해 스피커(SP)를 구동하게 되는 것이다.FIG. 1 is a block diagram of the present invention, when a value is not input to the terminal y (y ') when the recorded content is recorded on the tape recorder of the answering machine, is switched by the signal detecting circuit unit 3. The circuit unit 2 is' on 'and the switching circuit unit 2' is' off 'so that the recording of the tape recorder is amplified in the conventional amplifier circuit unit 1 so that the speaker SP is connected through the switching circuit unit 2. On the other hand, when a bell signal is input to the terminal y (y ') during the playback of the recording of the tape recorder, the switching circuit unit 2 is' off' by the signal detecting circuit unit 3 and the switching circuit unit 2 ') Is' on' so that the output of the amplifier circuit section 1 is cut off in the switching circuit section 2, and at the same time the input bell signal is oscillated in the tone ringer circuit section 4 of the passage, It will drive the speaker (SP) through.

제2도는 본 고안의 실시회로도로서, 통상의 앰프회로부(1)를 트랜지스터(Q1)(Q2) 및 저항(R1)으로된 스위칭회로부(2)를 통해 스피커(SP)에 연결하고, 다이오드(D1-D4), 콘덴서(C1)(C2), 트랜지스터(Q3)(Q4)및 저항(R2-R5)으로된 신호검출회로부(3)를 스위칭회로부(2)에 연결하는 한편, 통상의 톤링기회로부(4)와 트랜지스터(Q5)(Q6) 및 저항(R6)으로 된 스위칭회로부(2')를 통해 스피커(SP)에 연결한 구성이다.2 is an embodiment circuit diagram of the present invention, which connects a conventional amplifier circuit part 1 to the speaker SP through a switching circuit part 2 composed of transistors Q 1 and Q 2 and a resistor R 1 . The signal detection circuit section 3 comprising a diode D 1 -D 4 , a capacitor C 1 , C 2 , a transistor Q 3 , Q 4 , and a resistor R 2 -R 5 is provided with a switching circuit section 2. ) is the other hand, the configuration with a conventional tone Ferringhi circuit 4 and the transistor (Q 5) (Q 6) and a resistor (R 6) with the switching circuit section (2 ') to the speaker (SP) connected to.

미설명부호중 : y, y'는 벨신호 입력단자, B+는 직류전원입력단자, a, b, c는 회로의 각 점을 나타낸다.Unexplained code: y, y 'is a bell signal input terminal, B + is a DC power input terminal, a, b, c represents each point of the circuit.

상기와 같은 구성인 본 고안의 회로동작상태를 설명하면 아래와 같다.Referring to the circuit operating state of the present invention having the configuration as described above is as follows.

자동응답 전랜기는 테이프 레코오더를 내장하고 있어 전화가 길려오면 상대방에게 테이프에 기 녹음된 내용을 들려줄 수 있음은 물론 상대방의 전달내용을 녹음해 두므로서 나중에 이 녹음된 내용을 다시 재생하여 들을 수 있는 전화기로서, 이 자동응답 전화기의 녹음내용을 재생하여 듣는 경우에는 녹음기 재생신호가 앰프회로부(1)에서 증폭되어 스위칭 회로부(2)로 인가되는 것이며 신호검출회로부(3)의 단자(y)(y')로 벨신호가 입력되지 않는 한은 신호검출회로부(3)내의 a점으로는 아무런 전압도 공급되지 않으므로 트랜지스터(Q3)가 오프되어 B+전압이 저항(R3)및 저항(R1)을 통해 스위칭 회로부(2)내의 각 트랜지스터(Q1)(Q2)의 베이스에 공급되므로 이 트랜지스터(Q1)(Q2)가 도통되는 것이며 따라서 스위칭회로부(2)가 '온'상태로 되므로 상기의 앰프회로부(1)의 출력이 이 스위칭회로부(2)를 통해 스피커(SP)를 구동하여 주므로서 재생되는 녹음내용을 들을 수 있게 되는 것이다.The automatic answering machine has a built-in tape recorder so that if the phone is long, you can listen to the recorded contents on the tape and record the transmission of the other party. A telephone capable of reproducing, when reproducing and listening to the recorded contents of the answering machine, the recorder reproduction signal is amplified in the amplifier circuit section 1 and applied to the switching circuit section 2, and the terminal y of the signal detection circuit section 3 is provided. As long as the bell signal is not input to (y '), no voltage is supplied to the a point in the signal detection circuit section 3, so the transistor Q 3 is turned off so that the B + voltage is the resistor R 3 and the resistor R. 1 ) is supplied to the base of each transistor Q 1 (Q 2 ) in the switching circuit section 2, so that this transistor Q 1 (Q 2 ) is turned on and thus the switching circuit section 2 is in an 'on' state. As mentioned above The output of the amplifier circuit unit 1 drives the speaker SP through the switching circuit unit 2 so that the recording contents reproduced can be heard.

한편 상기의 녹음내용을 재생하여 듣고 있는 도중에 단자(y)(y')로 벨신호가 입력하게 되면 이 입력된 벨신호가 신호검출회로부(3)내의 다이오드(D1-D4) 및 콘덴서(C1)(C2)를 통해 정류, 평활된 직류전압으로 된 후 상기, 신호검출회로부(3)내의 a점으로 공급되는 것이며, 이로 인해 트랜지스터(Q3)가 도통되므로 b점의 전위가 무전위(Ovolt)로 되고 따라서 스위칭 회로부(2)내의 각 트랜지스터(Q1)(Q2)가 가 오프되므로 상기 스위칭 회로부(2)가 '오프'상태로 되어서 앰프회로부(1)의 출력이 상기 스위칭회로부(2)에서 차단되는 것이다.On the other hand, when a bell signal is input to the terminal y (y ') while the recording is being played and listened to, the input bell signal is inputted to the diodes D 1 -D 4 and the condenser in the signal detection circuit unit 3. After rectifying and smoothing the DC voltage through C 1 ) (C 2 ), it is supplied to the point a in the signal detection circuit unit 3. This causes the transistor Q 3 to conduct. Is turned on and thus each transistor Q 1 (Q 2 ) in the switching circuit section 2 is turned off, so that the switching circuit section 2 is turned off so that the output of the amplifier circuit section 1 is switched. It is cut off from the circuit section 2.

이와동시에 벨신호의 입력에 의해 a점에 공급된 직류전압은 저항(R4)을 통해 트랜지스터(Q4)의 베이스로도 인가되므로 트랜지스터(Q4)가 도통되어서 이 트랜지스터(Q4)의 출력 전압이 C점을 통해 통상의 톤링거회로부(4) 및 스위칭회로부(2')에 공급되지 때문에 스위칭회로부(2')내의 각 트랜지스터(Q5)(Q6)가 도통되어 스위칭회로부(2')가 '온' 상태로 되는 것이며, 동시에 상기 트랜지스터(Q4)의 출력전압이 톤링거회로부(4) 및 스위칭회로부(2')를 통해 스피켜(SP)를 구동시켜 주게 되므로 벨신호를 들을 수 있게 되는 것이다.At the same time, the DC voltage supplied to a point by the input of the bell signal is the resistance (R 4) the output of the transistor (Q 4) and the transistor (Q 4) are applied, so becoming the transistor (Q 4) interconnecting through the base of the via Since the voltage is not supplied to the ordinary toneringer circuit portion 4 and the switching circuit portion 2 'via the point C, each transistor Q 5 (Q 6 ) in the switching circuit portion 2' is turned on to switch the circuit portion 2 '. ) Is turned on, and at the same time, the output voltage of the transistor Q 4 drives the SP through the tone ringer circuit part 4 and the switching circuit part 2 'so that the bell signal is heard. It will be possible.

이상과 같이 본 고안은 자동응답 전화기에 있어서, 녹음내용을 재생하여 듣는 도중에 전화기 벨 신호가 입력하게 되면, 이에의해 앰프회로부를 오프시켜주는 동시에 입력된 벨신호를 톤링기회로를 통해 동일한 스피커를 구동시켜 주도록 안출한 것으로서, 벨신호가 입력되는 동안은 앰프회로부를 끊어주므로서 사용자가 전화벨소리를 명확하게 들을 수 있음은 물론 앰프회로부의 녹음내용과 톤링거 회로의 출력을 1개의 스피커로 구동시키도록 하므로서 제품의 크기 및 가격이 절감됨은 물론 제품의 고급화를 이룩한 유용한 고안인 것이다.As described above, in the present invention, when the telephone bell signal is input while playing and listening to the recording, the answering machine turns off the amplifier circuit, thereby driving the same speaker through the tone ringer circuit. It is designed to cut off the amplifier circuit part while the bell signal is being input, so that the user can clearly hear the telephone ringing, and to drive the recording of the amplifier circuit part and the output of the tone ringer circuit with one speaker. As a result, the size and price of the product is reduced, as well as a useful design to achieve high quality products.
