메 가 폰Megaphone

제1도는 본 고안의 실시회로도.1 is a circuit diagram of the subject innovation.

본 고안은 메가폰에 관한 것으로 특히 메가폰의 증폭부 입력측에 잭 일체의 2련 스위치를 구성하여 잭에 입력되는 외부저주파 출력과 마이크의 음성출력을 교호로 확성시키는 메가폰에 관한 것이다.The present invention relates to a megaphone, and more particularly, to a megaphone which alternately expands an external low frequency output and a voice output of a microphone by configuring a dual jack integrated switch on an input side of a megaphone.

종래에 공지된 이 종류의 메가폰에 있어서는 본 출원인의 선출원고안(공고번호 85-1791호)이 제안되어 있었다.In the conventionally known megaphones of this kind, the applicant's prior application draft (Notice No. 85-1791) has been proposed.

그러나, 이와 같은 메가폰은 라디오 수신회로가 메가폰 내부에 장치되어 있고 또 라디오 수신회로의 저주파출력단과 마이크를 선택스위치에 공통으로 접속시켜 라디오 수신음과 마이크를 교호로 절환확성되도록 하는 것이었으나, 항시 라디오 수신음만 수신되므로 카셋트녹음기나, 기타 앰프회로 또는 음향기기의 저주파출력등을 마이크와 함께 교호로 절환 확성시킬수가 없어 야외에서의 메가폰 사용시 원하는 카셋트 테이프 녹음이나 기타 앰프회로의 출력을 확성시킬수가 없었던 문제점이 있었다.However, such a megaphone has a radio receiver circuit installed inside the megaphone, and a low frequency output terminal and a microphone of the radio receiver circuit are commonly connected to a selector switch, so that the radio receiver sound and the microphone can be alternately and accurately exchanged. Since only low frequency output of cassette recorder, guitar amplifier circuit or sound equipment can be exchanged and expanded with microphone, it was not possible to increase the output of cassette tape recording or other amplifier circuit when using megaphone outdoors. there was.

이에 본 고안은 라디오의 출력뿐만 아니라 카세트 녹음기나 기타 각종 앰프회로의 음향기기의 출력을 임의로 마이크와 교호로 확성되도록 하여 메가폰의 확성대상을 보다 다양화하고자 하는 것이다.Therefore, the present invention is intended to diversify the megaphone's amplification target by allowing the output of a cassette recorder or an audio device of various amplifier circuits to be arbitrarily expanded with a microphone.

이를 첨부도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail based on the accompanying drawings.

본 고안은 잭기능과 2련 스위치의 기능이 결합되어 외부로 부터 저주파 출력단이 잭에 삽입되어지는 순간 2련 스위치가 절환되도록 하는 잭 스위치(가)와, 마이크(나), 볼륨(다), 증폭부(라), 훅크스위치(마), 전원(바), 스피커(사)로 구성된다.The present invention is a jack switch (a), a microphone (b), a volume (c), which combines the functions of a jack function and a double switch so that the double switch is switched when the low frequency output terminal is inserted into the jack from the outside. It consists of an amplifier part (d), a hook switch (e), a power supply (bar), and a speaker (company).

잭스위치(가)의 접점(a')측에는 항시 잭단자(d)로 부터의 출력이 볼륨(다)에 인가되도록 접속되며 접점(b')는 마이크(나)에 접속되며, 접점(b)는 전원(바)에, 접점(c)는 훅크스위치(마)에 각각 연결된다. 나머지 접점(a), (c')는 공접점단자이고 접점(e)는 어스단자이다.The contact (a ') side of the jack switch (a) is always connected so that the output from the jack terminal (d) is applied to the volume (c), and the contact (b') is connected to the microphone (b), and the contact (b) Is connected to the power supply (bar), the contact (c) is connected to the hook switch (e), respectively. The remaining contacts (a) and (c ') are co-contact terminals and contact (e) is an earth terminal.

즉, 스위치(가)에 외부출력기기의 코드가 끼워지면 잭(d)을 통하여 출력이 볼륨(다)에 인가됨과 동시에 접점(a')(b')이 오프(off)되고, 접점(b)(c) 사이가 온(ON)되어 전원(바)이 훅크스위치(마)에 무관하게 인가되게 구성된다.That is, when the cord of the external output device is inserted into the switch a, the output is applied to the volume c through the jack d, and at the same time, the contacts a 'and b' are turned off and the contacts b are (c) is turned on (ON) so that the power supply (bar) is applied irrespective of the hook switch (e).

이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

마이크(나)를 통한 음성의 확성은 제1도의 상태와 같이 오프(off)되어 있으므로, 훅크스위치(마)가 온접속되어야 증폭부(라)에 전원(바)이 인가되게 되며 이와 같은 전원(바)의 인가와 동시에 마이크(나) 음성 출력은 접점(b')와 접점(a')가 온되어 있으므로 화살표 "가"방향을 따라 볼륨(다)에 의하여 조절된 후 스피커(사)를 통하여 확성된 출력을 얻게 되는 것이다.Since the amplification of the voice through the microphone (b) is off as shown in FIG. 1, the power switch (bar) is applied to the amplifying unit (d) only when the hook switch (e) is turned on. F) The microphone (B) audio output at the same time the contact (b ') and the contact (a') are on, so that the arrow "a" is adjusted by the volume (a) along the direction, and then through the speaker (g). You will get the expanded output.

또한, 마이크(나)와는 무관하게 외부출력을 확성시키고자 할 경우에는 외부출력의 코드를 잭스위치(가)에 삽입시켜 출력이 "나"방향을 따라 볼륨(다)에 인가시키도록 하게 되며 이때, 접점(a)(b)와 접점(a')(b')는 절환되어 오프되며 접점(b)(c)가 온접속되므로 전원(바)이 접점(b)(c)를 거쳐 후크스위치(마)와는 무관하게, 증폭부(라)에 입력되어 확성준비를 하게 되며 접점(a')와 접점(b') 사이는 오프되어 마이크(나)의 출력은 끊어지게 된다.In addition, if you want to expand the external output irrespective of the microphone (b), insert the external output cord into the jack switch to apply the output to the volume along the "B" direction. , The contacts (a) (b) and the contacts (a ') (b') are switched off and the contacts (b) (c) are on-connected so that the power supply (bar) is hooked through the contacts (b) (c). Irrespective of E), the amplifier is input to the amplification unit D to prepare for amplification. The contact between the contact a 'and the contact b' is turned off so that the output of the microphone B is cut off.

따라서 잭(d)을 통하여 외부출력이 "나"방향으로 증폭부(라)에 인가되므로 볼륨(다)의 조절에 따라 외부출력이 스피커(사)를 통하여 확성케되는 것이다.Therefore, the external output is applied through the jack (d) to the amplification unit (d) in the direction of "b", and according to the adjustment of the volume (c), the external output is amplified through the speaker (sa).

이와 같이 본 고안은 외부출력을 카셋트녹음기 또는 각종 앰프기기등의 출력으로 임의선택할 수 있으므로 종래 라디오 수신회로만 마이크와 교호로 확성시키던 공지된 메가폰이 갖는 확성대상을 여러가지로 다양화할 수 있게 되는 유용한 고안이다.As such, the present invention can be arbitrarily selected as an output such as a cassette recorder or various amplifier devices, and thus it is a useful design that can be variously diversified in amplification targets of a known megaphone, in which only a conventional radio receiver circuit is alternately expanded with a microphone. .
