C先前技4标;J 習知技藝之說明 如習知技藝所示，在使用手機時，耳機用來維持個人 或通訊上的安全性，以在開車時減少干擾，或在使用Μ朽 2〇或音響時避免干擾其他人。尤其是，當使用一麥克風耳機 接收收音機或電視，觀看影片，或接收MP3檔案，或聽手 機的鈴聲，或在外面打電話時，可按下一語言選擇鈕，以 直接連接至浯言線並接電話。如此，耳機有多種功能。 當使用耳機作為單一物品時，很難攜帶，且耳機線常 200526058 會在使用或攜帶時扭曲或打結。此外，在公共場所，耳機 掉落常會干擾到他人。 解決這些問題的習知技術揭露在韓國新型專利 02007499，0170150以及0191754中（其内容加入本文中作為 5 參考資料）。 韓國新型0207499揭露如第1 a及1 b圖中所示的耳機線 殼1。 習知耳機線殼1包括一本體2，在其中間處有一突出芯 體部3，容納在内部中的捲線器4，一耳機9，一麥克風9a以 10 及一插孔6。捲線器4具有一圓筒形體5，定位在圓筒形體5 内部，且一端固定至突出芯體部3的一螺旋形彈簣如，以及 纏繞在其外部上，且同時分別連接至耳機9及插孔6的耳機 線9b及插孔線6a。 本體2具有一按紐8 ’其糟由定位在按钮§的一端之内部 15 上，且適於桃接捲線器4的外週邊表面的一葉片彈簧8b及一 止擋器8a彈性地支撐在其頂部的一側邊上。 當使用耳機9時，已纏繞在捲線器4上的耳機線9b藉由 朝向外拉動它而慢慢地鬆開。在使用耳機9之後，定位在本 體2的頂之一側邊上的按鈕8被壓下，以自轉動限制下鬆開 20捲線器4。然後，捲線器4藉由螺旋形彈簧5a的彈性儲存力 量而轉動，並以此方向捲繞耳機線9b。如此，耳機線外自 動地繞在捲線器4上並容納在本體2中。 然而，依據習知技藝的耳機線殼丨之嚴重的問題在於耳 機線9b及插孔線6a整合地相互連接，並繞在一單—捲線器* 200526058 上，且當耳機線9b拉動時，捲線器4的轉動造成插孔線％以 相反方向捲繞。因此，當插孔線6插入一手機的耳機或Mp3 播放機的插座中時，拉下耳機線9b，即阻播捲線器4的轉 動，且耳枝線9b不容易拉下。若耳機線外大力地拉動，耳 5機線卯及插孔線6a甚至會嚴重地扭曲，且在扭曲時無法適 當地捲繞。此外，若耳機線％在嚴重地扭曲時捲繞，則耳 機9會大力地轉動，因而容易受損。 為解決上述問題，韓國新型017〇15〇揭露一耳機線殼 Γ，如第2a及2b圖所示。 1〇 習知的耳機線殼1’包括一本體2，該本體具有定位在其 一側邊上的一耳機容納室9,，具有容納在内部中的一圓筒 形體5之一捲線器4，以及她接且面對捲線器4的一pCB。 在習知耳機線殼1’中，耳機線外及插孔線仏相互是分 開的，以解決其不良的繞捲及拉動問題，且使用一轉動接 15觸端子模式在其間作電力的接觸。 尤其疋，連接至耳機9及麥克風9a的耳機線9b大體上較 連接至插孔6的插孔線6a長；耳機線％繞捲在捲線器4的芯 體邛（軸)3的外週邊邊緣上；點端子％藉由在相對於螺旋形 彈黃（未顯示）的一側邊(第2b圖的捲線器4之右邊)上熔接與 2〇耳機線9b之而形成内部電線相同數量的螺旋形彈簧（未顯 示）。如此，它們在離心方向以預定的間隔定位，且以電力 連接至各別的内部電線；而較短的插孔線^之對應内部電 線經由導電跡線4c以電力連接至在PCB 4a±的各別圓形線 立而子4b，而該導電跡線4C接觸對應的圓形線端子朴。 200526058 因此，僅管在耳機線9b之拉動或繞捲而造成的捲線器4 之轉動時，具有與其連接的插孔線6b2PCB如仍維持固 定。即使在轉動時，在捲線器4上的各別點端子9c沿著一預 疋路徑移動，且接觸在PCB 4a上的對應圓形線端子仆。因 5此，可防止耳機線9b或插孔線6b扭曲。 然而，上述習知的耳機線殼或其他類似的習知耳機線 殼1’具有的嚴重問題在於，由於形成在捲線器4上的數個點 端子9c以及形成在PCB 4a上的數個對應的圓形線端子牝相 互作端子接觸，點端子9C可能會磨損且/*pcB4a可能會在 10捲線益4轉動次數增加時變形，而端子之間的接觸可能隨著 灰塵或異物進入或累積時降等。因此，物品的壽命會十分 短。此外，在談話或聽話時，電線很容易被干擾。如此會 破壞物品的可靠性。 此外，耳機線殼1，具有一無可避免的十分厚之厚度， I5因為其使用的較厚之硬PCB 4a，突出的點端子％形成在捲 線為4上，且插孔6的内部電線必須熔接在PCB牝上。耳機 線殼Γ亦具有一相當複雜的結構體以及大的尺寸。因此， 其在與手機或MP3—起使用時攜帶不方便，且用於汽車上 的免持單元時十分受限。 20 韓國新型0191754揭露如第3圖中所示的耳機線殼1”。 與上述韓國新型0170150相同的時，耳機線外及插孔線以相 互为開，以解決不良繞捲及拉動的問題，且採用一轉動接 觸端子模式，以在其間作電力接觸。 雖然未顯示於圖中，耳機線殼r具有一耳機線繞捲器 200526058 及一插孔線繞捲器，其分別定位在一PCB的左右兩側上， 而PCB具有形成在其兩個表面上的_圓形線端子，形成在 各別捲線器之-側表面上的一接觸端子，其面對⑽，在 捲線器的轉動下仍藉由一電刷連續地與圓形線端子作連續 5的接觸。然耳機線！，，非為扁平的，具有基本的結構體， 且其問題與韓國新型〇17()15()遭遇的問題相同，因此其重覆 的說明在此省略。 因此，扁平且精巧地足以容易地連接至已十分小的手 機之一耳機線殼可方便地與手機—起攜帶，不必擔心耳機 10或插孔線扭曲或變形，且有效地解決因不良接觸造成的語 言或收聽上的干擾。 C ^^明内】 發明之摘要 因此，本發明可解決習知技藝中的問題，且本發明的 15第一目的是藉由有效地防止一耳機，一麥克風耳機線，或 一插孔線扭曲，且完全地不須擔心由於不良接觸造成言談

personal or communication security to reduce interference when driving, or to use M 2. Or avoid disturbing others when playing. In particular, when using a microphone headset to receive radio or TV, watch videos, or receive MP3 files, or listen to the ringtone of a mobile phone, or make a call outside, you can press a language selection button to connect directly to the voice line and Answer the phone. As such, the headset has multiple functions. When using the headset as a single item, it is difficult to carry, and the headset cord 200526058 often twists or knots when used or carried. In addition, in public places, dropping the headset often disturbs others. Conventional technologies for solving these problems are disclosed in Korean new patents 02007499, 0170150, and 0191754 (the contents of which are incorporated herein as 5 references). The Korean new type 0207499 discloses the headphone case 1 shown in Figs. 1a and 1b. The conventional earphone wire shell 1 includes a body 2 with a protruding core portion 3 in the middle thereof, a cord reel 4 housed in the interior, an earphone 9, a microphone 9a to 10, and a jack 6. The cable reel 4 has a cylindrical body 5 positioned inside the cylindrical body 5 and fixed at one end to a helical elastic spring protruding from the core portion 3, and wound around the outside thereof, and simultaneously connected to the earphone 9 and the plug respectively. The earphone cable 9b and the jack cable 6a of the hole 6. The main body 2 has a button 8 'which is elastically supported by a leaf spring 8b and a stopper 8a positioned on the inner portion 15 of one end of the button § and adapted to the outer peripheral surface of the peach wire reel 4 On the top side. When the earphone 9 is used, the earphone wire 9b that has been wound on the cord reel 4 is slowly loosened by pulling it outward. After using the earphone 9, the button 8 positioned on the side of one of the tops of the body 2 is depressed to release the wire reel 4 under the restriction of self-rotation. Then, the cord reel 4 is rotated by the elastic storage force of the coil spring 5a, and the headphone cord 9b is wound in this direction. In this way, the headphone cord is automatically wound around the cord reel 4 and accommodated in the body 2. However, a serious problem of the earphone wire shell according to the conventional art is that the earphone wire 9b and the jack wire 6a are integrally connected to each other and wound around a single-winder * 200526058, and when the earphone wire 9b is pulled, the wire is wound. Rotation of the device 4 causes the jack wire% to be wound in the opposite direction. Therefore, when the jack cable 6 is plugged into the earphone of a mobile phone or the socket of an Mp3 player, the headphone cable 9b is pulled down, that is, the rotation of the broadcast reel 4 is blocked, and the ear branch cable 9b is not easily pulled down. If the earphone cable is pulled vigorously, the earphone cable 6 and the jack cable 6a will even be severely twisted, and cannot be properly wound when twisted. In addition, if the earphone cord is wound when it is severely twisted, the earphone 9 will be strongly rotated and thus easily damaged. In order to solve the above problems, a new Korean model 0170115 discloses a headphone wire casing Γ, as shown in Figs. 2a and 2b. 10 The conventional headphone cord housing 1 'includes a body 2 having a headphone accommodation chamber 9 positioned on one side thereof, a cord reel 4 having a cylindrical body 5 accommodated in the interior, and She picks up and faces a pCB of the reel 4. In the conventional earphone wire shell 1 ', the outer earphone wire and the jack wire 仏 are separated from each other to solve the problem of poor winding and pulling, and a rotary contact 15-contact terminal mode is used for electrical contact between them. In particular, the headphone cable 9b connected to the earphone 9 and the microphone 9a is generally longer than the jack cable 6a connected to the jack 6; the headphone cable is wound around the outer peripheral edge of the core 邛 (shaft) 3 of the reel 4 The upper point of the dot terminal% is formed by welding the same number of internal wires as the 20-headphone cable 9b by welding the side opposite to the spiral elastic yellow (not shown) (right side of the reel 4 of FIG. 2b). Shaped spring (not shown). In this way, they are positioned at predetermined intervals in the centrifugal direction and are electrically connected to the respective internal wires; and the corresponding internal wires of the shorter jack wire ^ are electrically connected to each of the PCBs 4a ± via the conductive trace 4c. The circular line is not upright 4b, and the conductive trace 4C contacts the corresponding circular line terminal. 200526058 Therefore, as long as the cord reel 4 is rotated by the pulling or winding of the headphone cord 9b, the PCB with the jack cord 6b2 connected to it remains fixed. Even at the time of rotation, the respective point terminals 9c on the wire reel 4 move along a predetermined path and contact the corresponding circular wire terminal terminals on the PCB 4a. Therefore, it is possible to prevent the headphone cord 9b or the jack cord 6b from being twisted. However, the above-mentioned conventional earphone wire shell or other similar conventional earphone wire shell 1 'has a serious problem in that due to the number of dot terminals 9c formed on the wire reel 4 and the corresponding ones of the dot terminals 9c formed on the PCB 4a The round wire terminals 牝 make contact with each other. The point terminal 9C may be worn and / * pcB4a may be deformed when the number of turns of 10 coils of wire 4 is increased, and the contact between the terminals may decrease as dust or foreign matter enters or accumulates. Wait. Therefore, the life of the item will be very short. In addition, the wires are easily disturbed during conversation or obedience. This will destroy the reliability of the item. In addition, the earphone wire shell 1 has an unavoidably very thick thickness, I5 because of its thicker hard PCB 4a, the protruding point terminal% is formed on the coil wire 4, and the internal wire of the jack 6 must be Welded on PCB 牝. The earphone wire casing Γ also has a rather complicated structure and a large size.

This configuration is substantially the same as that shown in FIG. 6, with the only difference being a stereo headphone 18 provided with a speaker 18c via a branch line 19e branched off from one end of a headphone line 19b connected to a headphone 19. This difference will be explained below. 5 As shown in FIG. 7, the other end of the headphone cable 19b is branched out and forms a branch line 19e having the plurality of internal wires 19d as described above, which is electrically connected to a connector 19c, and Connected to a stereo headset 18 via a headset jack 18a and a stereo headset cable 18b. Although the mono and stereo headphones 19 and 18 are separated from each other through the headphone jack 18a 10 and the connector 19c, the two headphones do not need to use the headphone jack 18a and the connector 19c, and are connected through the branch line 19e and the stereo headphone cable. One piece. Therefore, the 'earphone line 19b' and the earphone stereo terminal line in the internal wire of the jack line 16b of the sound device are connected to each other via a second headphone 18, 15 so that the user can hear music from a sound device, such as an MP3 player . Of course, the jack 16 is connected to a sound device such as an MP3 player. As described above, "the earphone wire shell according to the present invention uses a flexible PCB strip" which has a predetermined width sufficient to support a predetermined degree of ruggedness to connect an earphone wire to a jack wire. An elastic element (such as a spiral 20 spring or a rubber band) receiving portion and a flexible PCB strip receiving portion are positioned adjacent to each other. A cable reel assembly has a cable reel, which is provided with an earphone cable receiving portion positioned on the outside and a flexible PCB strip wound on it with an elastic element and placed in a casing Body. Therefore, the 'earphone, microphone earphone cable, or jack cable can effectively avoid twisting, and no call failure, degradation, or interference caused by bad contact. This guarantees good quality and durability. The earphone or microphone earphone cable can be easily pulled out of the casing with one hand, and wound in a tight manner to be placed in the casing for good convenience. The case can be easily and simply connected to a 5- or small-sized mobile phone, removed from the MP3 player, and easily carried after being attached to it. This ensures good portability. It is also possible to use a mono headset and a stereo headset at the same time, and at the same time, the monolithic or removable removable connection of the mono headset coupled with a flat compact earphone wire shell to the stereo headset can achieve a flat and compact size of the earphone shell 10 inches. Although a preferred embodiment of the present invention has been described and disclosed as above, those skilled in the art can understand various improvements, and it is possible to substitute within the scope defined in the spirit of the present invention and the scope of patent application.
