The earphone cord includes a positive line, a negative line, and a sheath covering the outer sides of the positive and negative lines. The existing positive and negative wires are made of high conductivity metal materials such as copper or aluminum. Due to the low flexibility of high conductivity metal materials such as copper or aluminum, the earphone cord of the above earphones is often covered in the sheath during use due to external tension or gravity, and repeated wraps. The positive and negative wires are broken, which causes the headset to not continue to be used. However, in addition to the earphone cable, the plug and the speaker are all good.

Referring to FIG. 2 together, the earphone cord 10 includes a first pole line 101, a second pole line 102, and a sheath 103 covering the outer sides of the first and second pole lines 101, 102. .

所述第一極線101包括有複數第一導線104以及至少一根奈米碳管線105。所述第一導線104可以與該奈米碳管線105並列排佈也可 以將第一導線104纏繞在該奈米碳管線105上形成一螺旋狀線材。這種纏繞方式可以進一步增加耳機線10之抗繞折度。如圖3所示為將第一導線104纏繞在奈米碳管線105上之結構示意圖。在圖3中僅示出一根第一導線104纏繞在一根奈米碳管線105上之結構示意圖。可以想到,當第一極線101包括複數第一導線104時,所有的第一導線104都可以採用這種纏繞方式。在本實施例中,所述第一導線104與該奈米碳管線105並行排佈。所述第一導線104之材質可以為銅、鋁、金等導電率高之金屬材料,在本實施例中,該第一導線104採用銅來製作。為了防止第一、第二極線101、102之間之導線之間發生短路,通常要在各第一導線104之外側刷有絕緣漆。該種刷有絕緣漆之第一導線104習慣稱之為漆包線。所述絕緣漆可以為搪瓷、塑膠、橡膠或高分子材料。可以理解的是,所述奈米碳管線105之外側也可以設置絕緣漆形成漆包線。 The first pole line 101 includes a plurality of first wires 104 and at least one nanocarbon line 105. The first wire 104 may be arranged side by side with the nano carbon line 105. A spiral wire is formed by winding the first wire 104 on the nanocarbon line 105.

In order to prevent a short circuit between the wires between the first and second electrode lines 101, 102, an insulating varnish is usually applied to the outer side of each of the first wires 104. The first wire 104 of the brushed with insulating varnish is customarily referred to as an enameled wire. The insulating varnish may be enamel, plastic, rubber or polymer material. It can be understood that the outer side of the nano carbon line 105 can also be provided with an insulating varnish to form an enameled wire.

所述奈米碳管線105在該耳機線10中用作一種承接元件,用來承受外界拉力或自重引起之拉力,或者係該耳機線在扭轉、扭曲時所產生之繞折力。當然可以想到,由於奈米碳管線105也具有良好的導電性,當第一導線105在使用中折斷了,奈米碳管線105還可以當作導線來用,從而可以進一步延長耳機之壽命。該奈米碳管線105可以為複數奈米碳管組成之非扭轉之奈米碳管線或扭轉之奈米碳管線。該奈米碳管線105之直徑可以為4.5奈米~100微米。該非扭轉之奈米碳管線可以將奈米碳管拉膜通過有機溶劑處理得到。請參見圖4,該非扭轉之奈米碳管線包括複數沿奈米碳管線長度方向排列並首尾相連之奈米碳管。優選地,該非扭轉之奈 米碳管線包括複數奈米碳管片段,該複數奈米碳管片段之間通過范德華力首尾相連,每一奈米碳管片段包括複數沿奈米碳管線之軸向相互平行並通過范德華力緊密結合之奈米碳管。該奈米碳管片段具有任意之長度、厚度、均勻性及形狀。該非扭轉之奈米碳管線長度不限,直徑為0.5奈米至100微米。所述奈米碳管線及其製備方法請參見范守善等人於2007年7月1日公開之第TW 200724486號台灣公開專利申請“奈米碳管絲及其製作方法”,申請人:鴻海精密工業股份有限公司。為節省篇幅,僅引用於此,但上述申請所有技術揭露也應視為本發明申請技術揭露之一部分。 The nanocarbon pipeline 105 is used as a receiving component in the earphone cord 10 for receiving tensile force caused by external tension or self-weight, or a bending force generated when the earphone cord is twisted or twisted. It is of course conceivable that since the nanocarbon line 105 also has good electrical conductivity, when the first wire 105 is broken in use, the nanocarbon line 105 can also be used as a wire, thereby further extending the life of the earphone. The nanocarbon line 105 can be a non-twisted nano carbon line or a twisted nano carbon line composed of a plurality of carbon nanotubes. The nanocarbon line 105 may have a diameter of from 4.5 nm to 100 microns. The non-twisted nano carbon pipeline can be obtained by treating a carbon nanotube film by an organic solvent. Referring to FIG. 4, the non-twisted nanocarbon pipeline includes a plurality of carbon nanotubes arranged along the length of the nanocarbon pipeline and connected end to end. Preferably, the non-twisted nene The carbon carbon pipeline includes a plurality of carbon nanotube segments, and the plurality of carbon nanotube segments are connected end to end by van der Waals force, and each of the carbon nanotube segments includes a plurality of axial carbon nanotubes which are parallel to each other and are closely coupled by van der Waals force. Combined with carbon nanotubes. The carbon nanotube segments have any length, thickness, uniformity, and shape. The non-twisted nano carbon line is not limited in length and has a diameter of 0.5 nm to 100 μm. For the nano carbon pipeline and the preparation method thereof, please refer to Taiwan Patent Application No. TW 200724486, published on July 1, 2007 by Taiwan, et al., "Nano Carbon Tube Wire and Its Manufacturing Method", Applicant: Hon Hai Precision Industry Co., Ltd. In order to save space, only the above is cited, but all the technical disclosures of the above application are also considered as part of the technical disclosure of the present application.

所述扭轉之奈米碳管線為採用一機械力將所述奈米碳管拉膜兩端沿相反方向扭轉獲得。請參見圖5,該扭轉之奈米碳管線包括複數繞奈米碳管線軸向螺旋排列之奈米碳管。優選地,該扭轉之奈米碳管線包括複數奈米碳管片段,該複數奈米碳管片段之間通過凡德瓦爾力首尾相連,每一奈米碳管片段包括複數相互平行並通過范德華力緊密結合之奈米碳管。該奈米碳管片段具有任意之長度、厚度、均勻性及形狀。該扭轉之奈米碳管線長度不限,直徑為0.5奈米~100微米。進一步地,可採用一揮發性有機溶劑處理上述扭轉之奈米碳管線。在揮發性有機溶劑揮發時產生之表面張力之作用下,處理後之扭轉之奈米碳管線中相鄰之奈米碳管通過凡德瓦爾力緊密結合,使扭轉之奈米碳管線之直徑及比表面積進一步減小,從而使其密度及強度進一步增大。可以理解,奈米碳管線105中之奈米碳管可以為單壁奈米碳管,雙壁奈米碳管或多 壁奈米碳管,或者係其組合。當所述奈米碳管線105為單壁奈米碳管時,該單壁奈米碳管之直徑可以為0.5奈米~50奈米。當所述奈米碳管線105為雙壁奈米碳管時,該雙壁奈米碳管之直徑可以為1奈米~50奈米。當所述奈米碳管線105為多壁奈米碳管時,該多壁奈米碳管之直徑可以為1.5奈米~50奈米。 The twisted nanocarbon pipeline is obtained by twisting both ends of the carbon nanotube film in a reverse direction by a mechanical force. Referring to FIG. 5, the twisted nanocarbon pipeline includes a plurality of carbon nanotubes arranged in an axial spiral arrangement around the carbon nanotubes. Preferably, the twisted nanocarbon pipeline comprises a plurality of carbon nanotube segments, and the plurality of carbon nanotube segments are connected end to end by Van der Waals force, and each of the carbon nanotube segments includes a plurality of parallel and pass van der Waals force Closely combined with carbon nanotubes. The carbon nanotube segments have any length, thickness, uniformity, and shape. The twisted nano carbon line is not limited in length and has a diameter of 0.5 nm to 100 μm. Further, the above twisted nanocarbon line may be treated with a volatile organic solvent. Under the action of the surface tension generated by the volatilization of the volatile organic solvent, the adjacent carbon nanotubes in the twisted nanocarbon pipeline after treatment are tightly bonded by the van der Waals force, so that the diameter of the twisted nanocarbon pipeline and The specific surface area is further reduced, thereby further increasing its density and strength. It can be understood that the carbon nanotubes in the nano carbon pipeline 105 can be single-walled carbon nanotubes, double-walled carbon nanotubes or more. Wall carbon nanotubes, or a combination thereof. When the nanocarbon line 105 is a single-walled carbon nanotube, the single-walled carbon nanotube may have a diameter of 0.5 nm to 50 nm. When the nanocarbon line 105 is a double-walled carbon nanotube, the double-walled carbon nanotube may have a diameter of 1 nm to 50 nm. When the nanocarbon line 105 is a multi-walled carbon nanotube, the multi-walled carbon nanotube may have a diameter of 1.5 nm to 50 nm.

可以理解,所述第一極線可以包括包括複數第一導線104和複數奈米碳管線105。該複數第一導線104與該複數奈米碳管線105可以並列排佈,該複數第一導線104也可以都纏繞在所述複數奈米碳管線105上。該複數第一導線104之根數與複數奈米碳管105之根數還可以相等,該複數第一導線104中之一根也可以僅僅纏繞在所述複數奈米碳管線105中之一根上。 It can be understood that the first polar line can include a plurality of first wires 104 and a plurality of nano carbon lines 105. The plurality of first wires 104 and the plurality of carbon nanotubes 105 may be arranged side by side, and the plurality of first wires 104 may also be wound around the plurality of carbon nanotubes 105. The number of the plurality of first wires 104 and the number of the plurality of carbon nanotubes 105 may be equal, and one of the plurality of first wires 104 may also be wound only on one of the plurality of carbon nanotubes 105. .

所述第二極線102僅包括複數第二導線106,不包括奈米碳管線。因為儘管在其徑向,奈米碳管具有很弱的導電性,但,如果正、負極線101、102都包括有所述奈米碳管線,其奈米碳管線間的短路,也會影響耳機線10之品質,進而會降低所述揚聲器11之音效品質。所述第二導線106與第一極線101之第一導線104有相同之結構與材質,因此在這裏不再贅述。為了使揚聲器11中之電訊號穩定,通常第一、第二極線101、102之阻值係相等的。為了達到使第一、第二極線101、102之阻值相等,可以採用具有相同參數之第一、第二導線104、106。所述參數包括第一、第二導線104、106之長度、直徑以及材質等。 The second pole line 102 includes only a plurality of second conductors 106, excluding the carbon nanotubes. Because although the carbon nanotubes have very weak conductivity in their radial direction, if the positive and negative lines 101, 102 include the nanocarbon pipeline, the short circuit between the carbon nanotubes will also affect The quality of the headphone cord 10, in turn, reduces the sound quality of the speaker 11. The second wire 106 has the same structure and material as the first wire 104 of the first electrode line 101, and therefore will not be described herein. In order to stabilize the electrical signal in the speaker 11, the resistance values of the first and second polar lines 101, 102 are generally equal. In order to achieve equal resistance values of the first and second polar lines 101, 102, first and second conductors 104, 106 having the same parameters may be employed. The parameters include the length, diameter, and material of the first and second wires 104, 106, and the like.

在這裏還需要進一步說明的是,所述第一、第二極線101,102可以分別連接於正極或負極中之任意一極以傳輸電訊號,且所述第 一極線101,插頭12以及第二極線102依次以串聯之方式電連接。可以理解,所述第一極線101,揚聲器11以及第二極線102依次也以串聯之方式電連接,以在第一極線101、插頭12、第二極線102以及揚聲器11之間形成一串聯回路,從而形成由一個插頭12開始,到第一極線101,再到揚聲器11,第二極線102,最後再回到插頭12的一個電流回路。 It should be further noted that the first and second polar lines 101, 102 may be respectively connected to any one of the positive pole or the negative pole to transmit a electrical signal, and the first The one-pole line 101, the plug 12 and the second pole line 102 are electrically connected in series in series. It can be understood that the first pole line 101, the speaker 11 and the second pole line 102 are also electrically connected in series in order to form between the first pole line 101, the plug 12, the second pole line 102 and the speaker 11. A series circuit is formed to form a current loop starting from a plug 12, to the first pole line 101, to the speaker 11, to the second pole line 102, and finally back to the plug 12.

所述護層103用於對該整個耳機線10特別係在第一、第二導線104、106外側之絕緣漆起保護作用。該護層103常選用之材料為聚氯乙烯、氯乙烯、可交聯聚乙烯、聚丙烯等中之一種或幾種。在本實施例中,該護層103由聚氯乙烯製備。 The cover layer 103 is used to protect the entire earphone cord 10 from the insulating paint on the outside of the first and second wires 104, 106. The material commonly used for the sheath layer 103 is one or more of polyvinyl chloride, vinyl chloride, crosslinkable polyethylene, polypropylene, and the like. In the present embodiment, the sheath layer 103 is made of polyvinyl chloride.

當第一、第二極線101、102在製備之過程中形成一圓柱形時,在該第一、第二極線101、102與護層103之間還應當填充有填充材料(圖未示)。該填充材料係為了使耳機線10相對圓整以利包裝,了為使該耳機線10結構穩定、內部結實,且在使用中受力均勻而不損壞耳機線10之內部結構。 When the first and second polar lines 101, 102 form a cylindrical shape during preparation, a filling material should also be filled between the first and second polar lines 101, 102 and the protective layer 103 (not shown) ). The filling material is used to make the earphone cord 10 relatively rounded for packaging, so that the earphone cord 10 is structurally stable, solid inside, and evenly stressed during use without damaging the internal structure of the earphone cord 10.

所述耳機線10進一步還包括一層設置於所述護層103與所述第一、第二極線101、102之間之屏蔽層107。該屏蔽層107係一種將耳機線10之電磁場與外界之電磁場進行隔離之元件。 The earphone cord 10 further includes a shielding layer 107 disposed between the sheath layer 103 and the first and second pole lines 101, 102. The shield layer 107 is an element that isolates the electromagnetic field of the headphone cord 10 from the electromagnetic field of the outside.

進一步地,當所述耳機線10包括複數第一、第二極線101、102的時候,如圖6如示,該屏蔽層107還應當分別設置在該複數第一、第二極線101、102之間以減少不同線組之間之電磁場影響。當該耳機線10中包括複數第一、第二極線101、102時,該耳機線10還 應當包括一填充物14。該填充物14填充於複數第一、第二極線101、102之間以使耳機線10之外徑相對圓整以利於包裝等,也可以使耳機線10結構穩定,結實,在使用中(拉伸、壓縮和彎曲時)受力均勻而不損壞電線之內部結構。 Further, when the earphone line 10 includes a plurality of first and second polar lines 101, 102, as shown in FIG. 6, the shielding layer 107 should also be respectively disposed on the plurality of first and second polar lines 101, Between 102 to reduce the influence of electromagnetic fields between different line groups.
