Abstract
본 고안은 유선전화기의 전화선에 장착하여 유선전화의 수화음량을 조절할 수 있도록 하였다. 유선전화를 사용중에 있어서 유선전화의 수화음량이 너무커서 개인의 사생활이 노출될 수 있고, 보안업무에 지장을 초래하는 일이 있는데, 이를 근본적으로 해결하여 통화중에 수화음량을 손쉽게 조절할 수 있도록 하였다.The present invention was designed to be able to adjust the volume of the telephone receiver's loudness by installing it on the telephone line of a landline telephone. When using a landline, the volume of the telephone is too loud to expose the privacy of the individual, and it may cause a problem to the security work. The solution is fundamentally solved so that the volume of the telephone can be easily adjusted during the call.
Description
정보통신의 비약적인 발전으로 인하여 이제는 유선전화 상호간 통화 시대가 아니라 유선대 모바일폰(이동전화)으로 그 통화로가 주를 이루고 있으며 모바일폰의 시간적 공간적 상황에 따라 그 전기적 특성의 차이로 인한 송,수화음량의 증폭도가 다르기 때문에 아날로그 방식인 유선전화의 수화음량의 조절은 꼭 필요할 것이며,대부분의 사무실 또는 가정에서 사용중인 저가형 유선 전화기에는 수화음량의 크기를 조절하는 기능이 없어서 통화중에 수화음량이 너무 크게들려 놀라거나 난처해 했던적이 있었으나 전화기 본체 내부에 기계식 볼륨조절장치를 삽입하여 생산한다면 고장 발생이 빈번하여 전화기의 본체를 통째로 바꿔야 하는 문제점이 있으며 전자식 볼륨조절장치를 전화기에 탑재하면 제조단가가 높아지는 단점이 있다.Due to the rapid development of information and communication, it is no longer the age of intercommunication between wired telephones, but the main route is the wired mobile phone (mobile phone), and the transmission and reception due to the difference in electrical characteristics according to the time and space situation of mobile phones. Because the volume of the amplification is different, it is necessary to adjust the volume of the telephone signal of an analog wired telephone, and the low-cost wired telephone used in most offices or homes does not have a function of adjusting the volume of the telephone signal. I was surprised or embarrassed to hear, but if the mechanical volume control device is inserted into the main body of the phone, there is a problem that the main body of the phone needs to be replaced as a whole due to frequent breakdowns, and the manufacturing cost increases when the electronic volume control device is mounted on the phone. There is this.
본 고안은 그러한 단점을 보안함과 동시에 일반전화기의 송수화기와 본체간에 연결되는 S 코드선의 수화기쪽 또는 전화기쪽 중의 어느쪽이든 부착이 가능하며 볼륨조절장치를 손쉽게 부착할 수 있도록 하여, 개인의 사생활 보호는 물론 기밀누설을 방지해줄 수 있도록 하였다.The present invention secures such shortcomings, and can be attached to either the handset side or the telephone side of the S code line connected between the handset and the main body of a general telephone, and the volume control device can be easily attached. Of course, it prevented the leakage of confidentiality.
본 고안은 전화기의 S코드선에 부착하여 사용하기 때문에 기존전화기에 쉽게 부착할 수 있도록 소형 경량화 하였으며, 현장에서 곧바로 사용이 가능하도록 제품생산이 가능하며 조립이 간편 하도록 하였다.Because the present design is attached to the S code line of the phone, it is compact and lightweight so that it can be easily attached to an existing phone, and the product can be produced and ready for easy use in the field.
도1:대표 도면으로서 볼륨조절장치 모습을 보여준다.1: shows a volume control device as a representative drawing.
도2:볼륨조절장치가 부착된 전화기를 보여준다.Figure 2: shows a phone with a volume control device attached.
도3:전화기 볼륨조절 장치 단면도이다.3 is a cross-sectional view of the telephone volume control device.
도4:볼륨조절장치에 부착된 반고정 저항의 구조를 보여준다.Figure 4: shows the structure of the semi-fixed resistor attached to the volume control device.
도1은 볼륨조절장치의 모습을 나타내며 전화기(6)의 본체 RJ포트(13) 또는 수화기의 RJ포트(14)에 삽입하는 RJ잭(5)과 연결선(4) 그리고 볼륨조절장치로 구성되어 있다.Figure 1 shows the appearance of the volume control device is composed of RJ jack 5, the connecting line 4 and the volume control device inserted into the main body RJ port 13 of the telephone 6 or RJ port 14 of the handset. .
도2는 유선전화기(6) 전화선(12)에 장착되어 전화기(6)와 수화기(7)를 연결하는 전화선(22)의 전화기(6)본체에 있는 RJ포트(13) 또는 수화기(7)쪽에 부착된 RJ포트(14)에 의해 삽입되는 볼륨조절장치(도1)가 부착된 모습을 보여준다.Fig. 2 shows the RJ port 13 or the receiver 7 of the telephone 6 of the telephone line 22 of the telephone line 22 which is mounted on the telephone line 12 of the telephone line 6 and connects the telephone 6 and the receiver 7. The volume control device (FIG. 1) inserted by the attached RJ port 14 shows the attached state.
도3은 볼륨조절장치(도1)의 내부 구조를 전자회로도로 표시한 볼륨조절장치를 나타낸 것으로 1번과 2번은 수화기(7)의 송화기쪽(송신)에 연결된 선이며 3번과 4번은 수화기(7)의 스피커(수신)로 연결된 선으로써 수화기의 스피커로 연결된선중 4번선에 반고정저항(도4)을 직렬로 연결한 모습을 나타낸다.Figure 3 shows a volume control device that shows the internal structure of the volume control device (Fig. 1) as an electronic circuit diagram 1 and 2 are lines connected to the transmitter (transmitter) of the handset 7 and the number 3 and 4 are the handset. It is a line connected with speaker (receive) of (7), and it shows the state that semi-fixed resistor (Fig. 4) is connected in series to line 4 of the line connected with speaker of receiver.
도4는 볼륨조절장치(도1) 내부에 들어있는 반고정저항(도4)의 모습을 나타낸 것으로 볼륨조절 손잡이(20)를 단자17 또는 단자 18쪽으로 움직여 전기저항 값을 조절하여 주며, 볼륨을 최대로 높였을때 전기저항의 값을 최소로 하기위하여 도4의 16번을 저항체(21)가 아닌 도체(19)로 구성하였다. 또한 전기저항의 값을 최대로 하였을때 수화음량이 완전히 안들리는 것을 방지 하기위하여 저항의 값은 30 KΩ 이하로 설정 하였다.Figure 4 shows the state of the semi-fixed resistor (Fig. 4) contained in the volume control device (Fig. 1) by moving the volume control knob 20 toward the terminal 17 or the terminal 18 to adjust the electrical resistance value, the volume In order to minimize the value of the electrical resistance at the maximum, the number 16 of FIG. 4 is composed of a conductor 19 rather than a resistor 21. In addition, the resistance value was set to 30 KΩ or less in order to prevent the hydration volume from being completely heard when the value of the electrical resistance was maximized.
본 고안은 전화기 생산과정에서 기계적 접촉에 의한 볼륨조절기능을 삽입하게 되었을때 고장발생이 빈번할 수 있고 또한 전자식 볼륨조절장치를 삽입하게 되면 생산단가가 높아지는 단점을 보안하여 기계식 볼륨조절 장치이면서도 외부에 부착하여 사용함으로써 고장발생이 있더라도 쉽게 탈.부착이 가능하여 전화기의 수명에는 지장을 주지 않는다.The present invention is a mechanical volume control device to secure the disadvantage that the production cost increases when inserting the electronic volume control device can be frequently occurred when the volume control function by mechanical contact in the phone production process. By attaching and using it, it can be easily attached and detached even if there is a failure, so it does not affect the life of the phone.
또한 수화음량을 손쉽게 조절 함으로써 개인의 사생활 침해를 예방할 수 있으며. 적절한 음량을 조절함으로써 편안하게 통화가 가능한 효과 및 장점이 있다In addition, the volume of the sign language can be easily adjusted to prevent privacy violations. By adjusting the appropriate volume, there is an effect and advantage that you can talk comfortably
