본 고안은 유무선을 겸용할 수 있게 구성된 경보음 송신마이크에 관한 고안인 바 용도에 따라 유선고 무선플럭을 마이크 잭에 접속하여 유무선을 겸용하여 사용할 수 있고, 특히 별개의 발진회로를 부가하여 부드럽고 안정된 경보음을 발성할 수 있게 하여 민방위 훈련용으로 사용할 수 있게 안출한 것이다.The present invention is designed for an alarm sound transmission microphone that can be used for both wired and wireless. The wired and wireless plug can be connected to the microphone jack and can be used for both wired and wireless. The alarm sound can be made to be used for civil defense training.

종래에도 경보음 송신 무선마이크가 제안된 것이 있으나, 이는 볼륨 콘트롤을 송신회로에다 구성하였음으로 발생되는 경보음이 단속음이 되어 청취하는데 불안정한 느낌을 주고 사용할 때에는 절환스위치를 경보음과 마이크를 별도로 조작하여야 되므로 불편한 점이 있었던 것이다.In the prior art, although a wireless microphone for transmitting an alarm sound has been proposed, this means that the alarm sound generated by the volume control configured in the transmission circuit becomes an intermittent sound, which gives an unstable feeling of listening. There was an inconvenience.

본 고안은 이러한 종래의 경보음 송신무선마이크의 결함을 시정하기 위하여 안출한 것으로 침부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is described in detail by the drawings immersed in order to correct the defect of the conventional alarm sound transmission wireless microphone as follows.

즉, 마이크(1) 내에 구성설치된 가변저항(VR)을 통한 음성신호가 트랜지스터(Tr1, Tr2, Tr3)를 통하여 안테나(NAT)로 발사되는 공지의 송신회로에 있어서 고주파발진부(A')의 트랜지스터(Tr2) 베이스의 입력선에 트랜지스터(Tr4, Tr5)로 구성되는 별개의 발진회로(B)를 접속하여 트랜지스터(Tr4, Tr5)의 베이스에 저항(R1, R2)과 콘덴서(C1) 푸시버튼 스위치(SW)를 연결하여 경보음을 발하고자 할 때에는 푸시버튼 스위치(SW)를 눌러주면 저항(R1)과 콘덴서(C1)의 시정수의충, 방전에 의하여 트랜지스터(Tr4)의 베이스 전압을 제어하여 주므로서 이에 따라 만곡선 파형 형태의 음파를 이루게 되어 이 음파가 고주파발진부(A')로 입력되어 안테나(ANT)를 통하여 발사되게 된다.That is, the high frequency oscillation unit A 'in a known transmission circuit in which a voice signal through the variable resistor VR configured in the microphone 1 is emitted to the antenna NAT through the transistors Tr 1 , Tr 2 , Tr 3 . A separate oscillation circuit (B) consisting of transistors (Tr 4 , Tr 5 ) is connected to the input line of the transistor Tr 2 base of the transistor Tr 2 and resistors R 1 , R are connected to the bases of the transistors Tr 4 , Tr 5 . 2 ) Press the pushbutton switch (SW) when the condenser (C 1 ) pushbutton switch (SW) is connected, and press the pushbutton switch (SW) to charge and discharge the time constant of the resistor (R 1 ) and the condenser (C 1 ). By controlling the base voltage of the transistor (Tr 4 ) thereby to form a sound wave in the form of a curved waveform, the sound wave is input to the high frequency oscillation unit (A ') is emitted through the antenna (ANT).

또한 발진회로(B)의 발진출력과 음성증폭부의 합지점인 트랜지스터(Tr2)의 베이스 입력선에 콘덴서 (C3)와 저항(R4)을 직열설치하여 플럭과 연결토록 하여 용도에 따라 안테나(ANT) 플럭(2)이나 유선플럭(3)을 접속하여 사용할 수 있게 한 것이다.In addition, the capacitor C 3 and the resistor R 4 are installed in series at the base input line of the transistor Tr 2 , which is the junction point of the oscillation output of the oscillation circuit B and the voice amplifier, so as to be connected to the plug. (ANT) The plug 2 or the wired plug 3 can be connected and used.

이와 같이 본 고안은 공지의 송신회로(A)에 트랜지스터(Tr4, Tr5)의 베이스에 저항(R1, R2)과 콘덴서(C1) 및 푸시버튼 스위치(TW)로 구성된 별개의 발진회로(B)를 부가시켜 이 구조에 의하여 시정수의 변화에 따라 만곡선 파형 형태의 음파를 발생시켜 경보음을 송신 무선마이크보다 청각적으로 부드러운 경보음을 얻을 수 있고, 이와 같이 구성하므로 푸시버튼스위치를 간단히 눌러만 주면 경보음이 발생하므로 특히 농어촌에서 민방위 훈련용으로 사용하기에 편리하며, 또한 사용용도에 따라 유선이나 무선으로 각각 임의 조정하여 사용할 수 있어 실용성이 있는 고안이다.As described above, the present invention is a separate oscillation composed of resistors R 1 and R 2 , a capacitor C 1 , and a pushbutton switch TW at the base of the transistors Tr 4 and Tr 5 in the known transmission circuit A. FIG. By adding a circuit (B), this structure generates sound waves in the form of curved lines in accordance with the change of time constant, and thus obtains an alarm sound that is softer than the wireless microphone. It is convenient to use for civil defense training especially in farming and fishing villages because it generates alarm sound just by pressing a switch, and it is a practical design that can be arbitrarily adjusted by wire or wireless according to the usage.
