본 고안은 텔레비젼과 음성 다중 텔레비젼 및 오디오 제품의 음성 신호 점검용 테스터에 관한 것으로 특히 휴대에 간편하고 음성 신호를 직점 이어폰(earphone)으로 청취할수 있고 발광다이오우드(LED)의 점등으로 직접회로(IC)의 불량유무를 점검할수 있어 신속하고 정확한 점검을 하는데 적당하도록한 텔레비젼의 음성부 성능 점검용 테스터에 관한 것이다.The present invention relates to a tester for checking the voice signal of a television, an audio multi television and an audio product, and is particularly portable and can listen to a voice signal through a direct earphone, and the integrated circuit (IC) is turned on by the light emitting diode (LED). The present invention relates to a tester for checking the performance of the audio portion of a television, which is capable of checking whether there is a defect, and which is suitable for quick and accurate checking.

종래 텔레비젼의 음성부 또는 음성 다중 텔레비젼 및 오디오 제품의 음성 IC의 성능을 점검할 경우에는 부피가 크고 무거운 멀티테스터(MulTi-TESTER)를 이용하여 음성Ic의 핀에 리드봉을 접속하므로써 직류(DC)전압이나 저항치를 점검하여 집적회로(IC)의 이상 유무를 점검하였다.When checking the performance of the audio section of a conventional television or audio IC of an audio multi TV and an audio product, a direct current (DC) is connected by connecting a lead rod to the pin of the audio IC using a bulky and heavy multi-tester (MulTi-TESTER). Check the voltage and resistance to check the integrated circuit (IC).

또한 텔레비젼의 음성 집적 회로(IC)를 점검할 경우 정확한 전압이 집적회로(IC)의 핀에 출력되어도 음이 찌그러지는 불량이 발생하면 집적회로의 불량 유무를 판단하는데는 많은 시간이 소모되면 콘덴서의 불량 발생시에는 멀티 테스터의 부피가 크고 고가이며 사용 방법이 복잡한 결함이 있었다.Also, when checking the IC's audio integrated circuit (IC), if the sound is distorted even though the correct voltage is output to the pin of the integrated circuit (IC), it is necessary to determine whether the integrated circuit is defective. In the event of a failure, the multitester was bulky, expensive, and complicated to use.

따라서 본 고안은 상기한 결함을 개선시킬 목적으로 텔레비젼 성능 점검시에 휴대가 간편하고 발광다이오우드(LED)의 동작 유무에 따라 집적회로의 이상 유무를 점검할수 있고 이어폰을 장착하여 음성 신호를 직접들으면서 회로를 추적 점검할수 있으므로 집적회로(IC)의 성능 점검을 신속하고 정확하게 하려는 것이다.Therefore, the present invention is easy to carry when checking the TV performance for the purpose of improving the above-mentioned defect, and can check the abnormality of the integrated circuit according to the operation of the light emitting diode (LED), and the earphone is mounted to listen directly to the audio signal This allows for quick and accurate performance checks of integrated circuits (ICs) as they can be traced back.

따라서 본 고안에 따른 성능 점검용 테스터의 기술 구성은 다음과 같다.Therefore, the technical configuration of the tester for performance check according to the present invention is as follows.

제1도와 제2도에 도시한 바와 같이 텔레비젼 음성부의 성능 점검용 테스터에 있어서 전단에 리드봉(4a)을 형성하고 측면에 구멍(4b)을 뚫어 발광다이오우드(LED)를 끼우고 후단에는 이어폰 잭(3)과 클립(5)에 연결된 리드선(5a)을 연결한 감지봉(4)에 리드봉(4a)과 연결된 단자(1)를 제너다이오우드(ZD1)와 콘덴서(C1)의 접속점에 연결하고 제너다이오우드(ZD1)를 발광다이오우드(LED)에 연결하고 발광다이오우드(LED)를 저항(R)에 연결하여 단자(2)에 연결되도록하고 콘덴서(C1)를 이어폰 잭(3)에 연결하며, 이어폰 잭(3)을 단자에 연결한 음성 IC 점검 회로(10)를 내장시켜 발광다이오우드(LED)와 이어폰의 동작에 따라 텔레비젼 음성부의 성능을 점검하도록한 구성이다.As shown in FIG. 1 and FIG. 2, in the tester for checking the performance of a television audio section, a lead rod 4a is formed at the front end, a hole 4b is drilled at the side, and a light emitting diode (LED) is inserted. (3) and the sensing rod (4) connecting the lead wire (5a) connected to the clip (5), the terminal (1) connected to the lead rod (4a) to the connection point of the Zener diode (ZD 1 ) and the capacitor (C 1 ) Connect the Zener diode (ZD 1 ) to the light emitting diode (LED), connect the light emitting diode (LED) to the resistor (R) so that it is connected to the terminal (2), and connect the capacitor (C 1 ) to the earphone jack (3). It is connected to the built-in voice IC check circuit (10) connecting the earphone jack (3) to the terminal is configured to check the performance of the TV audio unit according to the operation of the light emitting diode (LED) and the earphone.

발광다이오우드(LED)를 통해 저항(R1)에 연결되고 저항(R1)은 단자(2)에 연결하며, 콘덴서(C1)는 이어폰 잭(3)을 통해 단자(2)에 연결되며 단자(2)는 접지 접속된 구성인 음성 IC 점검 회로(10)를 내장한 구성이다.The light emitting diode (LED) is connected to the resistor (R 1 ), the resistor (R 1 ) is connected to the terminal (2), the capacitor (C 1 ) is connected to the terminal (2) through the earphone jack (3) and the terminal (2) is a structure incorporating the voice IC check circuit 10 which is a structure connected with ground.

상기한 구성인 본 고안은 음성다중 텔레비젼 및 오디오 제품의 음성 IC의 핀에 테스터의 리드봉(4a)을 접속하면 검파된 음성 신호가 리드봉(4a)에 인가되어 이어폰 잭(3)에 전달된다.According to the present invention having the above-described configuration, when the lead rod 4a of the tester is connected to the pins of the voice IC of the voice multiple television and audio products, the detected audio signal is applied to the lead rod 4a and transmitted to the earphone jack 3. .

이때 이어폰을 이어폰 잭(3)에 장착시키면 음성 IC의 음성 출력신호를 직접 청취하게 되어 음성 신호의 이상 유무를 판별할수 있다.In this case, when the earphone is mounted on the earphone jack 3, the voice output signal of the voice IC is directly listened to, thereby determining whether or not the voice signal is abnormal.

따라서 음성 다중 텔레비젼 및 오디오 제품의 성능 점검시에 음성 IC의 핀에 리드봉(4a)을 접속하여 이어폰으로 직접 출력 신호를 청취하면서 점검하므로써 2개 국어 및 스테레오시의 성능 점검을 간단한 방법으로 정확하게 점검할수 있다.Therefore, when checking the performance of voice multi-TV and audio products, the lead rod 4a is connected to the pin of the voice IC to check the performance of bilingual and stereo by simply checking by listening to the output signal directly through the earphone. can do.

예를 들어 설명하면 제3도에 도시한 바와 같이 클립(5)을 접지접시키고, 리드봉(4a)을 다중 회로의 음성IC(LSC 1008 P)의 핀(8)에 연결하면 검파되어 출력된 신호가 리드봉(4a)과 콘덴서(C1)를 통해 이어폰 잭(3)에 인가되고, 이어폰을 장착하면 음성 신호를 청취할 수 있다.For example, as shown in FIG. 3, when the clip 5 is grounded and the lead rod 4a is connected to the pin 8 of the voice IC (LSC 1008 P) of the multiple circuit, it is detected and outputted. The signal is applied to the earphone jack 3 through the lead rod 4a and the condenser C 1 , and when the earphone is mounted, a voice signal can be heard.

이때 출력되는 음성 신호를 매우 작은 신호이므로 핀(14)으로 입력되어 중간주파 증폭기를 통해 증폭되어 핀(12)으로 출력된다.At this time, since the output audio signal is a very small signal, it is input to the pin 14 and amplified by the intermediate frequency amplifier and output to the pin 12.

따라서 리드봉(4a)을 핀 (12)에 접속하면 크고 정확한 오디오 신호를 청취할수 있고, 상기한 방법으로 모든 회로를 추적 점검할 수 있다.Therefore, when the lead rod 4a is connected to the pin 12, a large and accurate audio signal can be heard, and all the circuits can be tracked and checked in the above-described manner.

또한 발광다이오우드(LED)를 이용하여 음성 IC의 불량유무를 점검할 경우에는 상기한 방법과 동일하게 리드봉(4a)을 음성 IC의 핀에 접속하면, 음성IC의 출력이 "하이"인 경우(약12V)리드봉(4a)은 단자(1)에 연결되어 있으므로, 상기한 "하이" 신호는 제너다이오우드(ZD1)를 통해 발광다이오우드(LED)에 인가되어 발광다이오우드(LED)는 동작하게 되며 음성 IC가 불량이거나 파괴된 경우에는 "로우" 상태가 되므로 발광다이오우드(LED)는 동작하지 않고 오프된다.In addition, when checking whether the voice IC is defective using the light emitting diode (LED), if the lead rod 4a is connected to the pin of the voice IC in the same manner as described above, the output of the voice IC is " high " 12V) Since the lead rod 4a is connected to the terminal 1, the "high" signal is applied to the LED through the Zener diode ZD 1 so that the LED is operated. If the voice IC is defective or destroyed, the LED is turned off because the LED is turned off.

즉 음성 IC의 불량 유무에 따라 발광다이오우드(LED)가 점등 또는 소등되므로 음성IC의 성능을 간단하고 신속하게 점검할수 있다.That is, the light emitting diode (LED) is turned on or off depending on whether or not the voice IC is defective, so the performance of the voice IC can be checked simply and quickly.

따라서 본 고안은 매우 간단한 구조로 되어 있으며 조작 방법도 매우 간단하며 텔레비젼 또는 오디오 제품의 음성부의 불량 발생시에 멀티 테스터로써 직류전압이나 저항값을 점검하여 제품의 성능을 점검하므로 발생되는 시간의 낭비와 콘덴서 또는 음성 IC의 음성이 찌그러지는 불량 상태를 점검할수 없던 결함을 완전히 개선시키기 위해 이어폰을 사용하여 출력되는 음성 신호를 청취하면서 성능 점검을 하므로써 정확한 성능 점검을 할수 있는 효과가 있다.Therefore, the present invention has a very simple structure, a very simple operation method, and a waste of time and condenser caused by checking the performance of the product by checking the DC voltage or resistance value with the multi tester in case of failure of the audio part of the TV or audio product. Or in order to completely improve the defect that could not check the bad state of the voice IC distortion, it is possible to check the performance by listening to the audio signal output using the earphones, so that the accurate performance check can be performed.

또한 발광다이오우드(LED)의 동작상태에 따라 음성 IC불량 상태 유무를 판별하므로써 신속한 점검을 할수 있다. 즉 본 고안에 따른 텔레비젼의 성능 점검용 테스터는 음성 다중 텔레비젼 및 오디오 제품의 성능 점검시에 정상적인 전압이 출력되어도 음성신호가 찌그러지는 경우 이어폰을 장착하여 음성 신호를 청취하면서 점검을 하므로써 음성 IC의 성능을 정확하게 점검할수 있으며 발광다이오우드(LED)를 이용하여 음성 IC의 동작상태에 따라 발광다이오우드(LED)가 점등 또는 소등되므로 신속하게 성능을 점검할수 있고 점검 작업이 간단하며, 구조가 단순하여 원가가 저렴하고 휴대하기 편리한 장점이 있다.In addition, it is possible to perform a quick check by determining the presence or absence of a voice IC defective state according to the operation state of the light emitting diode (LED). In other words, the performance tester of the TV according to the present invention performs the performance of the voice IC by listening to the voice signal by attaching an earphone when the voice signal is distorted even when normal voltage is output during the performance check of the voice multi-TV and audio products. Can be checked accurately, and the light emitting diode (LED) is turned on or off according to the operation state of the voice IC by using the light emitting diode (LED), so the performance can be checked quickly, the inspection work is simple, the structure is simple, and the cost is low. It has the advantage of being convenient to carry.
