본 고안은 별도의 송수화장치인 스피커와 마이크를 사용하지 않고 1개의 이어폰에 의하여 송수화를 할 수 있게한 이어폰을 이용한 송수화 장치에 관한 것으로, 특히 본 고안은 1개의 이어폰을 사용하여 평상시 대화하는데로 말을 하여 말할 때 떨리는 성대의 진동에 의한 음파가 인후관을 통하여 이어폰에 전달되어 검출되면 이 신호를 상대방에게 절달하게 하여 상호 송수화를 할 수 있도록 한 것이다.The present invention relates to a handset using an earphone that allows handset by one earphone without using a separate handset, a speaker and a microphone, and in particular, the present invention uses a single earphone to talk normally When the sound wave caused by the vibration of the trembling vocal cords is transmitted to the earphone through the throat tube and detected, the signal is delivered to the other party for mutual handset.
일반적인 무선방식에 의한 송수화장치(소위 무선기)에 있어서는 스피커와 마이크를 내장하게 되어 그 부피가 크므로서 외부에서 무선기의 휴대, 사용이 쉽사리 노출되는 보안 및 사용상의 문제점이 있었다.In general wireless handsets (so-called radios), since the speaker and the microphone is built-in, the volume is large, there is a problem in the security and use that is easy to carry and use the radio from the outside.
본 고안은 상기와 같은 문제점을 감안하여 스피커와 마이크를 전혀 사용하지 않고 사용자가 이어폰을 귀에 꽂은채로 이어폰을 통하여 송수화를 하게 됨으로서 외부에서의 무선 통화 상태를 쉽사리 감지할 수 없이 보안상의 문제점을 해소함과 동시 그 회로구성이 간단하여 휴대에 극히 간편하게 할수 있도록 한 것으로 이를 첨부된 도면에 의하여 그 구조를 상세히 설명하면 다음과 같다.The present invention solves the security problem by not allowing the user to easily detect the state of the wireless call from the outside by allowing the user to make and receive the phone through the earphone without the speaker and the microphone at all. Simultaneously, the circuit configuration is simple, so that the portable device is extremely simple. The structure will be described in detail with reference to the accompanying drawings.
즉 트랜스(T)의 2차측코일(L1), (L2)을 각각 릴레이(Ry)의 제1노오멀 오픈(normal open) 접점(NO1)과 노오멀 클로우즈(normal close) 접점(NC1)에 각각 접속하고 제1노오멀 오픈 및 클로우즈 접점(NO1)(NC1)에 각각 릴레이(Ry)의 제2노오멀 오픈 접점(NO2) 및 노오멀 클로우즈 접점(NC2)을 접속연결한다.That is, the secondary coils L 1 and L 2 of the transformer T are respectively connected to the first normal open contact NO 1 and the normal close contact NC of the relay Ry. 1 ) and connect the second normal open contact (NO 2 ) and the normal close contact (NC 2 ) of the relay Ry to the first normal open and close contact (NO 1 ) (NC 1 ), respectively. Connect.
릴레이(Ry)의 제2노오멀 오프 접점(NO2)에는 콘덴서(C1)를 통하여 증폭회로(IC)의 출력단과, 감도조절용 가변저항(VR)을 통하여 릴레이(Ry)의 제3노오멀 오픈 접점 (NO3)을 병렬로 접촉하고, 릴레이(Ry)의 제2노오멀 클로우즈 접점(NC2)에는 콘덴서 ( C2)를 통하여 증폭회로(IC)의 입력단과 제3노오멀 클로우즈 접점(NC3)에 접속하고 릴레이(Ry)의 제3노오멀 클로우즈 및 오픈 접점(NC3),(NO3)에 이어폰(1)을 접속 연결한다.The second normal off contact NO 2 of the relay Ry is connected to the output terminal of the amplification circuit IC through the capacitor C 1 and the third normal of the relay Ry through the variable resistor VR for sensitivity adjustment. The open contact NO 3 is brought into contact in parallel, and the second normal close contact NC 2 of the relay Ry is connected to the input terminal of the amplifying circuit IC and the third normal close contact through the capacitor C 2 . NC 3 ), and the earphone 1 is connected to the third normal close and open contacts NC 3 and NO 3 of the relay Ry.
또한 각 제1, 제2, 제3노오멀 오픈 및 노오멀 클로우즈 접점군(NO1)(NC1), (NO2)(NC2), (NO3)(NC3)구동용 릴레이(Ry)에는 송화용 푸시버튼(PB)가 접속된다.In addition, each of the first, second, and third normal open and normal close contact groups (NO 1 ) (NC 1 ), (NO 2 ) (NC 2 ), (NO 3 ) (NC 3 ) Is connected to a push button PB.
도면중 R는 저항, LED는 표시램프, D1은 다이오드, C3,C4,C5,C6은 콘덴서,L3, L4는 트램스(T)의 1차측이다.In the figure, R is the resistance, LED is the display lamp, D 1 is the diode, C 3 , C 4 , C 5 , C 6 is the capacitor, L 3 , L 4 is the primary side of the tram T.
이와 같이 구성된 본 고안의 작용 효과를 상세히 설명하면 이어폰(1)을 귀에 꽂은 상태에서 수화시에는 안테나(도시없음)을 통해 들어온 상대방의 음성신호는 트랜스(T)의 2차측 코일(L1)(L2)에 유기되는데 이때 코일(L1)은 릴레이(Ry)의 제1노오멀 오픈접점(NO1)과 접속되어 회로가 개방되어 있으므로서 코일(L2)에 유기된 신호만 콘덴서(C3)-제1노오멀 클로우즈 접점(NC1)-제2노오멀 클로우즈 접점(NC2)-콘덴서(C2)를 통하여 증폭회로(IC)에 입력되어 증폭된 다음 콘덴서(C1)-가변저항(VR)-제3노오멀 오픈 접점(NO3)을 통해 이어폰(1)으로 전달되어 수화하게 되는데 이때 가변저항(VR)으로서 수신음을 조절할 수 있게 되는 것이다.When explaining the operation effect of the present invention configured in this way in detail when the earpiece 1 is plugged into the ear, the voice signal of the other party through the antenna (not shown) is the secondary coil (L 1 ) of the transformer (T) ( L 2 ), but the coil L 1 is connected to the first normal open contact NO 1 of the relay Ry, and the circuit is open, so that only the signal induced in the coil L 2 is condensed. 3 )-First normal close contact (NC 1 )-Second normal close contact (NC 2 )-Input to amplification circuit (IC) through capacitor (C 2 ) and then amplified and then condenser (C 1 ) -Variable The resistor VR is delivered to the earphone 1 through the third normal open contact NO 3 to hydrate the variable sound VR.
이와 같이 수화한 후 송화코져 할 때에는 릴레이(Ry)와 접속된 송화용 푸시버튼(PB)을 누르면 릴레이(Ry)가 여자되어 릴레이(Ry)의 접점이 모두 노오멀 클로우즈 상태에서 노오멀 오픈상태로 절환되어 송화상태로 절환되고 이때 송화자는 평상시와 같이 송화내용을 말하면 성대의 진동에 의한 음파가 인후관을 통하여 이어폰(1)에 전달되어 이어폰(1)의 진동판이 진동하게 되고 이 신호가 제3노오멀 클로우즈 접점(NC3)-콘덴서(C2)-증폭회로(IC)-콘덴서(C1)-제2노오멀 오픈 접점(NO2)-제1노오멀 오픈접점-코일(L3)을 통하여 흐르게 되고 이에따라 트랜스(T)의 1차측에 그 신호가 유기되어 안테나(도시없음)를 통하여 상대방에게 송화되게 되는 것이다.When the call is made after receiving the hydration in this way, when the push button PB connected to the relay Ry is pressed, the relay Ry is excited and all the contacts of the relay Ry are switched from the normal closed state to the normal open state. When the talker talks about the contents of the conversation as usual, the sound waves caused by the vibration of the vocal cords are transmitted to the earphone 1 through the throat tube, and the vibrating plate of the earphone 1 vibrates, and this signal is the third signal. Mullen closed contact (NC 3 ) -capacitor (C 2 ) -amplifier circuit (IC) -capacitor (C 1 ) -second normal open contact (NO 2 ) -first normal open contact-coil (L 3 ) Through this, the signal is induced on the primary side of the transformer T and transmitted to the other party through an antenna (not shown).
이와 같은 본 고안은 1개의 이어폰과 릴레이 구동에 따른 송수화회로 절환에 의한 간단한 회로 구성 방법으로 송수화를 가능하게 하므로서 그 회로 구성이 간편하여 제작이나 휴대사용이 간편할뿐만 아니라 외부에서 무선기 사용 여부를 식별할 수 없게 되어 보안상 완벽을 기할 수 있는 매우 유용한 실용적인 유용한 고안인 것이다.The present invention as described above allows the handset by a simple circuit configuration method by switching the handset circuit according to one earphone and the relay drive, and thus the circuit configuration is simple, making it easy to manufacture or carry, as well as using a radio from the outside. It is a very useful practical design that can not be identified and can be perfected for security.
