Description
本發明涉及一種音響設備之附件，特別係關於一種耳機線及具有該耳機線之耳機。 The present invention relates to an accessory for an audio device, and more particularly to an earphone cord and an earphone having the same.
如今，越來越多的音像用戶，如手機、MP3等，使用耳機來連接呼叫或者答復呼叫，從而在答復或呼叫期間，該用戶可以騰出雙手來做其他的一些事情，如操作PC，而且在人多的環境中，戴著耳機欣賞音像產品可以避免打擾到別人。因此。耳機得到了越來越多的應用。 Nowadays, more and more audio and video users, such as mobile phones, MP3s, etc., use headphones to connect calls or answer calls, so that during the reply or call, the user can free up his hands to do other things, such as operating a PC. And in a crowded environment, listening to audiovisual products with headphones can avoid disturbing others. therefore. Headphones are getting more and more applications.
通常之耳機包括一根耳機線，一個電性連接於該耳機線一端之插頭以及一個電性連接於該耳機線另一端之揚聲器。所述耳機線包括一根正極線、一根負極線以及包覆於所述正、負極線之外側之護層。現有之正、負極線都係由銅或鋁等高導電率金屬材料製成的。由於銅或鋁等高導電率金屬材料柔韌性較低，因此上述耳機之耳機線常常會在使用過程中，由於外界之拉力或者自身之重力，以及反復之繞折，而使得包覆在護層中之正、負極線斷裂，從而導致該耳機不能繼續使用。但是除了耳機線，插頭以及揚聲器都是良好的，如果僅因為耳機線之抗繞折度之不足，而造成整個耳機之損壞而丟掉該耳機，會造成很大的浪費，且不利於環保。 A typical earphone includes a headphone cord, a plug electrically connected to one end of the headphone cord, and a speaker electrically connected to the other end of the headphone cord. 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 headphone cable, the plug and the speaker are all good. If the earphone wire is damaged due to insufficient anti-winding of the earphone wire, the earphone is damaged and the earphone is lost, which causes great waste and is not environmentally friendly.
有鑒於此，有必要提供一種具有高抗繞折度之耳機線以及具有該耳機線之耳機。 In view of the above, it is necessary to provide a headphone cord having high wrap resistance and an earphone having the same.
一種耳機線，其包括一根第一極線，一根第二極線，一個設置在所述第一極線與第二極線之間之絕緣層，一個包覆在所述第二極線外面之絕緣護層。所述第一極線和第二極線都分別包括至少一根導線。所述第一極線和第二極線中至少一極線還包括至少一根奈米碳管線。 A headphone cord comprising a first pole line, a second pole line, an insulating layer disposed between the first pole line and the second pole line, and one covering the second pole line Insulating sheath on the outside. The first pole line and the second pole line each include at least one wire. At least one of the first and second polar lines further includes at least one nanocarbon line.
一種耳機，其包括一根上述之耳機線，一個電性連接於所述耳機線一端之揚聲器以及一個電性連接於所述耳機線另一端之插頭。 An earphone comprising a speaker cable as described above, a speaker electrically connected to one end of the earphone cable, and a plug electrically connected to the other end of the earphone cable.
與先前技術相比，由於奈米碳管本身所具有之優異之機械性能，該奈米碳管製備之奈米碳管線也具有較好之抗繞折度，因此具有該奈米碳管線之耳機線，其抗繞折度也會得到很大的提高，從而降低耳機之損壞率。 Compared with the prior art, due to the excellent mechanical properties of the carbon nanotube itself, the carbon nanotube prepared by the carbon nanotube has good resistance to wrap, so the earphone with the nano carbon pipeline The line, its anti-winding degree will also be greatly improved, thereby reducing the damage rate of the earphone.

The speaker 11 generally includes a sounding coil (not shown) and a diaphragm (not shown) that is adhered to the sounding coil. When an electrical signal is sent to the sounding coil through the earphone cord 10, the sounding coil generates a reciprocating axial force to drive the diaphragm to move back and forth axially and vibrate back and forth to generate sound. In the present embodiment, the earphone 100 has two speakers 11, two earphone wires 10. The two earphone cords 10 are connected to the two speakers 11 in the same manner.
所述插頭12用來與所述訊號發生器電性連接。該插頭12包括一個正極和一個負極。該正、負極分別與第一、第二極線101、102電性相連，且該正、負極相互絕緣。在本實施例中，所述插頭12之正、負極分別與兩根耳機線10中之第一、第二極線101、102電性 相連。 The plug 12 is used to be electrically connected to the signal generator. The plug 12 includes a positive pole and a negative pole. The positive and negative electrodes are electrically connected to the first and second polar lines 101 and 102, respectively, and the positive and negative electrodes are insulated from each other. In this embodiment, the positive and negative poles of the plug 12 and the first and second pole lines 101 and 102 of the two earphone wires 10 are respectively electrically Connected.
由於奈米碳管本身所具有的優異的機械性能，由該奈米碳管製備之奈米碳管線也具有強大的抗繞折度，因此具有該奈米碳管線之耳機線，其抗繞折度也會得到很大的提高，從而降低耳機之損壞率。同時，奈米碳管與其他材料在相同直徑之情況下，奈米碳管具有更強之抗拉性，因此在保持與其他材料的抗拉性不變之要求下，可以進一步降低耳機線之整體直徑。另外，奈米碳管之密度相較於先前之材料小，因此具有該奈米碳管之耳機線之重量較輕。 Due to the excellent mechanical properties of the carbon nanotube itself, the nano carbon pipeline prepared from the carbon nanotube has a strong anti-winding property, so the earphone cord of the nano carbon pipeline is resistant to winding. The degree will also be greatly improved, thereby reducing the damage rate of the headphones. At the same time, the carbon nanotubes and other materials have the same diameter, the carbon nanotubes have stronger tensile properties, so the headphone wire can be further reduced while maintaining the same tensile resistance as other materials. Overall diameter. In addition, the density of the carbon nanotubes is smaller than that of the prior materials, so that the headphone cord having the carbon nanotubes is lighter in weight.
