본 고안은 일반적인 무선통신 단말기의 이어폰 잭을 이용하여 외부 디바이스에 전력을 공급해 줄 수 있는 이어폰 3극짹을 통한 전원 공급 기능을 가진 무선통신 단말기에 관한 것이다.The present invention relates to a wireless communication terminal having a power supply function through a three-pole earphone jack that can supply power to an external device using an earphone jack of a general wireless communication terminal.
일반적으로 이어폰은 음성재생매체(예:오디오 카셋트 플레이어, MP3 플레이어 등)로부터 재생된 음성을 청취할 수 있는 장치로서, 이제는 위와 같이 단순히 듣기만 하는 기능에서 진일보하여 음성을 송신할 수 있는 기능까지로 확대되고 있다. 이러한 기능은 특히 무선통신 단말기를 이용한 통화시 손이 부자연스러울 때 이용되는 '핸즈프리' 기능에 채택이 되어 무선통신 단말기 사용의 편리성을 배가시켜 주고 있다.In general, earphones are devices that can listen to voices played from voice playback media (e.g., audio cassette player, MP3 player, etc.). It is expanding. This feature is especially adopted for the 'hands-free' function, which is used when the hand is unnatural during a call using the wireless communication terminal, which doubles the convenience of using the wireless communication terminal.
상기의 기술을 보다 일반화 시키면 종래의 이어폰은 단순히 신호의 수신만이 가능하였으나 이제는 송신도 가능하게 되었고, 이어폰이 연결되는 디바이스의 회로를 어떻게 구성하느냐에 따라서 이어폰을 통해 단순 음성뿐만이 아닌 다른 신호의 송수신도 가능하다는 결론에 도달하게 된다.If the above-mentioned technology is more generalized, the conventional earphone can only receive a signal, but now it is also possible to transmit and transmit and receive not only simple voice but also other signals through the earphone depending on how the circuit of the device to which the earphone is connected. The conclusion is that it is possible.
본 고안은 이와 같은 원리에 착안하여 안출된 것으로서 본 고안의 목적은 무선통신 단말기의 배터리 전원을 무선통신 단말기의 이어폰 잭을 통하여 외부 디바이스에 공급 가능하게 하는 회로를 구비한 무선통신 단말기를 제공함에 있다.The present invention has been made in view of the above principle, and an object of the present invention is to provide a wireless communication terminal having a circuit which can supply battery power of a wireless communication terminal to an external device through an earphone jack of the wireless communication terminal. .
도1은 본 고안에 따른 무선통신 단말기의 사시도.1 is a perspective view of a wireless communication terminal according to the present invention.
도2는 본 고안에 따른 회로도.2 is a circuit diagram according to the present invention.
상기와 같은 목적을 달성하기 위해 본 고안에서는 스위칭 소자를 사용하여 스위칭 소자의 상태에 따라 정상 통화를 하거나 비통화시에는 무선통신 단말기의 배터리에 상기 마이크 라인 또는 스피커 라인이 상기 전원부에 결선되어 외부 디바이스에 전원 공급이 가능한 구조로 되어 있다.In order to achieve the above object, in the present invention, when a normal call or a non-call is performed using a switching element, the microphone line or the speaker line is connected to the power supply part of the battery of a wireless communication terminal to connect an external device. It has a structure that can supply power.
도1은 본 고안에 따른 무선통신 단말기의 외관 형태를 나타내는 사시도로서, 무선통신 단말기(100)의 측면에 이어폰 잭(101)을 구비하고 있다.1 is a perspective view showing the appearance of a wireless communication terminal according to the present invention, and is provided with an earphone jack 101 on the side of the wireless communication terminal 100.
또한, 도2a 및 도2b는 본 고안에 따른 회로구성도를 나타낸다..2A and 2B show a circuit configuration according to the present invention.
상기 도면에서, 무선통신 단말기의 이어폰 잭(101)은 수신되는 음성의 청취에 관계되는 스피커 출력 라인 단자(L1), 음성의 송신에 관계되는 마이크 입력 라인 단자(L2)을 포함하며 두개 트랜지스터(TR1,TR2)의 스위칭 동작 특성에 의하여 무선통신 단말기가 '통화 모드' 일 때와 '비통화 모드' 일 때의 마이크 라인 및 스피커 라인의 상태를 제어할 수 있다.In the figure, the earphone jack 101 of the wireless communication terminal includes a speaker output line terminal L1 related to the reception of the received voice, a microphone input line terminal L2 related to the transmission of the voice, and two transistors TR1. According to the switching operation characteristic of TR2), the state of the microphone line and the speaker line when the wireless communication terminal is in the 'call mode' and the 'non-call mode' can be controlled.
상기 스위칭 동작 특성에 의한 마이크 입력 라인(L2) 및 스피커 출력 라인(L1)의 상태를 다음의 표1에 정리를 한다.The states of the microphone input line L2 and the speaker output line L1 according to the switching operation characteristics are summarized in Table 1 below.
'통화 모드'와 '비통화 모드'는 제2트랜지스터(TR2)의 베이스 단자에 연결된 통신 모드 설정부(20)의 제어 신호에 따라 결정이 되며 이는 무선통신 단말기의 'SEND' 키에 의해 설정이 되거나 플립의 개폐 여부 혹은 후크-온오프 신호에 의해 설정이 된다.The 'call mode' and 'non-call mode' are determined according to the control signal of the communication mode setting unit 20 connected to the base terminal of the second transistor TR2, which is set by the 'SEND' key of the wireless communication terminal. Or by a hook-on / off signal.
위의 표를 참조하면 제2트랜지스터의 베이스 단자가 'High' 상태 일 때(두 트랜지스터가 도통(ON)되었을때) 상기 마이크 단자 또는 스피커 단자는 배터리(10)에 결선이 되어 배터리의 전원을 이어폰 잭으로 공급시킴을 알 수 있다. 외부 디바이스(라디오)0를 이어폰 잭에 연결시키면 무선통신 단말기으로부터 전원을 공급받아 디바이스를 구동시킬 수 있다.Referring to the table above, when the base terminal of the second transistor is 'high' (when both transistors are turned on), the microphone terminal or the speaker terminal is connected to the battery 10 to supply power to the battery. It can be seen that the jack is supplied. When the external device (radio) 0 is connected to the earphone jack, the device can be driven by receiving power from the wireless communication terminal.
본 고안의 무선통신 단말기를 이용하면 어떤 디바이스의 배터리가 소진 되었을 때 현대인이 거의 필수적으로 가지고 있는 무선통신 단말기의 배터리 전원을 이용하여 상기 디바이스의 구동을 간단히 시킬 수 있으며 아울러 무선통신 단말기의 활용성도 높일 수 있다.The wireless communication terminal of the present invention can simplify the operation of the device by using the battery power of the wireless communication terminal, which is almost essential for modern people when the battery of a device is exhausted, and improve the usability of the wireless communication terminal. Can be.
