본 발명은 이어폰 볼륨 조절장치용 엘리먼트 및 그 제조방법에 관한 것으로, 더욱 상세하게는 전극층의 내구성을 향상시켜 작동의 신뢰성을 향상시킴은 물론 잔류저항을 최소화하여 작동초기 음고현상을 방지토록 한 것이다.The present invention relates to an element for earphone volume control device and a method of manufacturing the same, and more particularly, to improve the reliability of the operation by improving the durability of the electrode layer, and to minimize the residual resistance to prevent the initial operation of the pitch.

주지하다시피, 이어폰은 전기적 신호를 음성신호로 변조하여 사용자의 귀에 꽂을 수 있는 크기의 스피커를 통해 출력하는 도구로서, 스피커를 통해 출력되는 음성정보의 볼륨을 조절할 수 있도록 이어폰의 신호선상에는 볼륨조절장치가 구비된다.As is well known, the earphone is a tool that modulates an electrical signal into a voice signal and outputs it through a speaker sized to be plugged into the user's ear, and the volume control device on the signal line of the earphone to control the volume of voice information output through the speaker. Is provided.

이러한 볼륨조절장치는 베이스인 합성수지재 엘리먼트(10) 중앙부에 도 1과 같이 작동공(11)이 천공되고, 작동공(11) 주위에는 카본으로 이루어진 가변저항층(12)이 인쇄되고, 이러한 가변저항층(12)과 직접적 또는 간접적으로 연결되는 3개의 전극층(20)(30)(40)이 각각 형성되는데, 가변저항층(12)과 직접 연결되는 제 1전극층(20)과 제 3전극층(40)은 물론 컨택터에 의해 가변저항층(12)과 선택적으로 접촉되는 제 2전극층(30) 모두 은(21)(31)(41)으로 인쇄되어 이루어지고, 각 전극층(20)(30)(40)에는 3개의 단자(13)(14)(15)가 각각 연결되며, 그 위에는 하면에 컨택터를 갖는 노브(미도시)가 회전가능하게 고정되어 노브를 회전시키면 컨택터가 가변저항층(12)과 접촉되면서 그 볼륨 가변값에 따라 가변저항값이 출력되어 이러한 가변저항값에 따라 출력되는 음성정보의 크기가 조절되는 것이다.This volume control device is a hole in the center of the synthetic resin element 10 as a base 11 as shown in Figure 1, the variable resistance layer 12 made of carbon is printed around the operating hole 11, such a variable Three electrode layers 20, 30 and 40 are directly or indirectly connected to the resistance layer 12, respectively. The first electrode layer 20 and the third electrode layer (which are directly connected to the variable resistance layer 12) are formed. The second electrode layer 30 selectively contacting the variable resistance layer 12 by the contactor 40 is, of course, printed with silver 21, 31, 41, and each electrode layer 20, 30. Three terminals 13, 14, and 15 are respectively connected to the 40, and a knob (not shown) having a contactor on the lower surface thereof is rotatably fixed thereon so that the contactor becomes a variable resistance layer when the knob is rotated. While contacting with (12), the variable resistance value is output according to the variable value of the volume, and the magnitude of the voice information output according to the variable resistance value. Is controlled.

그러나, 상기한 일반적인 이어폰 볼륨용 엘리먼트에서는 각 전극층이 모두 은으로만 이루어져 있으므로 은의 특성상 내구성이 떨어져 단자 병접시 은 인쇄부위가 들뜨는 문제가 유발되어 간헐 작동 불량의 문제가 있음은 물론 그 수명이 짧고, 제 1단자와 제 2단자간 잔류저항이 3Ω 이상으로 높게 형성됨에 따라 이러한 높은 잔류저항이 볼륨 작동초기 단자로 출력되는 저항값에 영향을 주어 볼륨 작동초기 음고(音高)현상 등의 노이즈가 발생되는 문제가 있었다.However, in the above general earphone volume element, each electrode layer is made of only silver, so the durability of the silver is poor, causing problems of silver printing at the terminal bottle contact, causing a problem of intermittent operation failure, as well as short lifespan. As the residual resistance between the 1st terminal and the 2nd terminal is formed higher than 3Ω, this high residual resistance affects the resistance value output to the initial volume operation terminal, resulting in noise such as initial volume operation. There was a problem.

본 발명은 이러한 점을 감안하여 제안된 것으로, 제 1전극층과 제 3전극층의 컨택터 접촉부위만 은으로 인쇄하고, 이를 제외한 모든 전극층은 금동박으로 형성함으로써 내구성을 향상시켜 작동의 신뢰성을 향상시키고, 또 제 1단자와 제 2단자간 잔류저항을 최소화하여 작동초기 음고현상을 개선토록 한 이어폰 볼륨 조절장치용 엘리먼트 및 그 제조방법을 제공하고자 하는 것이다.The present invention has been proposed in view of this point, and only the contactor contact portions of the first electrode layer and the third electrode layer are printed with silver, and all electrode layers except this are formed of gold copper foil, thereby improving durability and improving operation reliability. Another object of the present invention is to provide an element for earphone volume control device and a method of manufacturing the same, which minimize the residual resistance between the first terminal and the second terminal to improve the initial pitch.

이하, 본원 발명을 제시되는 실시예와 첨부된 도면에 따라 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 이어폰 볼륨 조절장치용 엘리먼트의 구성도이고, 도 3은 본 발명에 따른 이어폰 볼륨 조절장치용 엘리먼트의 제조공정도이다.Figure 2 is a block diagram of the element for the earphone volume control device according to the invention, Figure 3 is a manufacturing process of the element for the earphone volume control device according to the invention.

이어폰 볼륨 조절장치의 베이스인 엘리먼트(100)는 통상 에폭시 수지로 구성되며, 그 중앙부에 작동공(101)이 천공되고, 이 작동공(101) 주위에는 카본으로 이루어진 가변저항층(102)이 형성되며, 이 가변저항층(102)과 직접적 또는 간접적으로 연결되는 3개의 전극층(120)(130)(140)이 각각 형성되며, 각 전극층(120)(130)(140)에는 제 1단자(103), 제 2단자(104) 및 제 3단자(105)가 각각 연결되고, 그 위에는 하면에 컨택터를 갖는 노브(미도시)가 회전가능하게 고정되어 이루어진다.The element 100, which is a base of the earphone volume control device, is usually made of epoxy resin, and an operating hole 101 is drilled in the center thereof, and a variable resistance layer 102 made of carbon is formed around the operating hole 101. Each of the three electrode layers 120, 130, 140, which are directly or indirectly connected to the variable resistance layer 102, is formed on each of the electrode layers 120, 130, 140. ), The second terminal 104 and the third terminal 105 are connected to each other, and a knob (not shown) having a contactor on the lower surface thereof is rotatably fixed thereto.

이러한 엘리먼트(100)의 전극층(120)(130)(140)에서 제 1전극층(120)과 제 3전극층(140)의 컨택터 접촉부위는 은(121)(141)으로 인쇄되고, 이를 제외한 제 1전극층(120)과 제 3전극층(14) 및 제 2전극층(130)은 금동박(122)(132)(142)으로 형성한 것이다.The contactor contacting portions of the first electrode layer 120 and the third electrode layer 140 in the electrode layers 120, 130 and 140 of the element 100 are printed with silver 121 and 141, except for those. The first electrode layer 120, the third electrode layer 14, and the second electrode layer 130 are formed of gold copper foils 122, 132, and 142.

즉, 은(121)(141)에 비해 내구성 및 도전성이 뛰어난 금동박(122)(132)(142)을 각 전극층(120)(130)(140)의 일부분만 제외하고 모두 형성한 것이다.That is, all of the gold foils 122, 132 and 142, which are more durable and conductive than silver 121 and 141, are formed except a part of each electrode layer 120, 130 and 140.

그런데, 은의 경우 인쇄를 통해 엘리먼트(100)의 위에 형성하게 되므로 그 두께를 매우 얇게 구현할 수 있어 컨택터와의 접촉시 걸림 현상이 없으나, 금동박의 경우 인쇄를 통해 형성할 수 없어 엘리먼트(100) 표면에 미리 동박과 금도금을 형성한 후 원하는 부위를 남기고 에칭, 현상하여 부식 제거해주는 과정으로 그 패턴을 형성하게 되므로 두께가 은에 비해 높아지게 되며, 따라서 이러한 금동박을 제 1전극층(120)과 제 3전극층(140)에서 컨택터 접촉부위까지 형성할 경우 컨택터와의 접촉시 걸림현상을 초래할 수 있어 부득이 제 1전극층(120)과 제 3전극층(140)에서는 컨택터 접촉부위에는 은(121)(141)을 인쇄하여 구성한 것이다.However, since silver is formed on the element 100 through printing, the thickness thereof may be very thin so that there is no jam when contacting the contactor, but in the case of gold copper foil, the element 100 may not be formed through printing. Copper foil and gold plating are formed on the surface in advance, and the pattern is formed by etching, developing, and removing corrosion by leaving a desired portion, and thus the thickness thereof becomes higher than that of silver. Thus, the copper foil is made of the first electrode layer 120 and the first. In the case of forming the contactor contact portion from the third electrode layer 140, a contact phenomenon may occur when contacting with the contactor. Therefore, in the first electrode layer 120 and the third electrode layer 140, silver 121 is formed on the contactor contact portion. 141 is printed and constructed.

이와 같이 구성하게 되면 노브를 회전시켜 컨택터를 가변저항층(102)과 접촉시킴에 따라 가변저항값이 출력되어 이어폰의 볼륨을 조절할 수 있는 기능은 기존의 이어폰 볼륨 조절장치와 동등하게 수행할 수 있다.In this configuration, the function of adjusting the volume of the earphone by outputting the variable resistance value as the contactor contacts the variable resistance layer 102 by rotating the knob can be performed in the same way as the existing earphone volume control device. have.

또한, 각 전극층(120)(130)(140)의 대부분이 금동박(122)(132)(142)으로 이루어지므로 내구성 및 도전성이 뛰어나게 되어 기존 은으로만 이루어진 전극층에 비해 작동의 신뢰성을 향상시킬 수 있고, 각 전극층(120)(130)(140)의 단자 연결부위가 모두 내구성이 뛰어난 금동박(122)(132)(142)으로 이루어지므로 단자(103)(104)(105) 병접시 들뜸 현상이 전혀 없어 간헐작동 불량과 같은 문제가 전혀 없어지는 것이다.In addition, since most of the electrode layers 120, 130 and 140 are made of gold copper foils 122, 132 and 142, the durability and conductivity are excellent, thereby improving reliability of operation compared to the electrode layer made of silver. The terminal connection portions of the electrode layers 120, 130, and 140 are all made of copper foils 122, 132, and 142, which are highly durable, so that the terminals 103, 104, and 105 are lifted up in parallel. There is no problem at all, so there is no problem such as intermittent malfunction.

특히, 제 1단자(103)와 제 2단자(104) 사이의 잔류저항이 1Ω이하로 최소화 되어 작동초기 음고현상과 같은 노이즈의 발생도 최소화할 수 있는 것이다.In particular, the residual resistance between the first terminal 103 and the second terminal 104 is minimized to less than 1Ω to minimize the occurrence of noise, such as the initial operation pitch.

이상에서 설명한 바와 같이, 본 발명은 기존에 은으로만 이루어진 전극층 대신 컨택터 접촉부위를 제외하고 모든 전극층을 금동박으로 구성한 것이므로 이어폰 볼륨 조절장치로서의 기능은 기존의 것과 동등하게 구현할 수 있으며, 금동박의 특성에 따라 내구성이 향상되어 작동의 신뢰성을 향상시킬 수 있고, 컨택터 병접시 들뜸현상을 없앨 수 있으며, 특히 제 1단자와 제 2단자 사이의 잔류저항이 1Ω이하로 최소화될 수 있어 작동초기 음고현상과 같은 노이즈의 발생을 억제할 수 있는 매우 유용한 효과가 있는 것이다.As described above, the present invention is because all the electrode layer except for the contactor contact portion instead of the electrode layer made of silver in the conventional gold foil foil, so that the function as an earphone volume control device can be implemented equivalent to the existing, gold copper foil Depending on the characteristics of the durability can be improved to improve the reliability of operation, and eliminate the lifting phenomenon when contactor parallel, especially the residual resistance between the first terminal and the second terminal can be minimized to less than 1Ω There is a very useful effect that can suppress the occurrence of noise, such as pitch.
