擾到別人。因此。耳機得到了越來越多的應用。 [0003] 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。 【發明内容】 [0004] 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。

Nanoclay-polymer composite material, nano-clay-based nano-layered structure of citrate mineral, composed of complex hydration >6 acid salt and a certain amount of oxidation, metal oxide and soil metal oxide It has excellent properties such as fire retardant and flame retardant, such as nano kaolin or nano montmorillonite. The polymer material may be selected from the group consisting of an anthracene resin, a polyamide, a polyolefin such as polyethylene or polypropylene, but is not limited thereto. This embodiment is preferably a foamed polyfetone composition. The second pole line 102 includes a plurality of second conductors 107 and at least one second nanocarbon line 108. The second wire 107 has the same structure and material as the first wire 105, and details are not described herein. The plurality of second wires 107 and the second nanocarbon wires 108 are evenly arranged on the outer side of the insulating layer 103 to form a coaxial cable structure with the first electrode lines 101. In order to stabilize the electrical signal in the speaker 11, the resistances 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 conductive lines 105, 107 having the same parameters may be employed. The parameters include the length, diameter, and material of the first and second wires 105, 107, and the like. [0018] 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 of the plug 12 to transmit an electrical signal, and the first polar line 101 The plug 12 and the second pole line 102 are sequentially electrically connected in series. It can be understood that the first pole line 101, the speaker 11 and the second pole line 102 are also connected in series by way of 098128595 form number Α0101 page 9 / total 22 page 0982049096-0 201108265, thereby forming a plug 12 Go to the first pole line 101, then to the speaker 11, the second pole line 102, and finally back to a current loop of the plug 12. [0019] The sheath 104 is used to protect the entire earphone cord 10 from the second conductor 107 and the second nanocarbon pipeline 108 of the second pole line 102. The protective layer 104 may be a composite material of nano-clay and a polymer material, wherein the nano-clay may be nano-kaolin or nano-montmorillonite, and the polymer material may be enamel resin, polyamide, polyolefin, such as polyethylene or polypropylene. , but not limited to this. This embodiment is preferably a nano montmorillonite-polyethylene composite material, which has good mechanical properties, fire-retardant flame retardancy, low smoke and no A performance, and can not only provide protection for the earphone cord 10, but also effectively resist mechanical, physical or chemical externalities. Damage, while still meeting the requirements of environmental protection. [0020] The earphone cord 10 further includes a shielding layer 109 disposed between the sheath 104 and the second pole line 102. The shield layer 109 is an element that isolates the electromagnetic field of the headphone cord 10 from the electromagnetic field of the outside. The shield layer 109 is formed of a conductive material for shielding electromagnetic interference or unwanted external signal interference. Specifically, the shielding layer 109 may be woven by a plurality of metal wires or wound with a metal film outside the second pole line 104, or may be a plurality of nano carbon pipelines, a single-layer ordered carbon nanotube film, and a plurality of layers of ordered nanometers. The carbon tube film or the disordered carbon nanotube film is wound or wound around the second electrode line 104, or may be directly coated on the surface of the insulating layer 104 by a composite material containing a carbon nanotube. [0021] Further, when the earphone cord 10 includes a plurality of first and second polar lines 101, 102, as shown in FIG. 6, the mask layer 109 should also be respectively set to 098128595 form number A0101 page 10 / A total of 22 pages 0982049096-0 201108265 between the first and second pole lines 101, 102 to reduce the electromagnetic field between different sets of lines. When the first and second polar lines 101, 102 are included in the earphone cord 10, the earphone cord 10 should also include a filler 14. The filler 14 is filled between the plurality of first and second polar lines 101 and 102 to make the outer diameter of the earphone cord 10 relatively round to facilitate packaging, etc., and the headphone cord 10 can be structurally stabilized and solid, in use ( When stretching, compressing and bending, the force is uniform without damaging the internal structure of the wire. [0022] The speaker 11 is an electroacoustic conversion device that converts an electrical signal from the earphone cord 10 into an acoustic signal. The speaker 11 generally includes a sound coil (not shown) and a diaphragm (not shown) that is adhered to the sound 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. [0023] 插头 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 electrode 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 are electrically connected to the first and second pole lines 101 and 102 of the two earphone wires 10, respectively. [0024] 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, and thus has the earphone cord of the nano carbon pipeline. The anti-winding degree is also greatly improved, thereby reducing the damage rate of the earphone. At the same time, the carbon nanotubes and other materials in the same diameter, the carbon nanotubes have stronger tensile properties 098128595 Form No. Α0101 Page 11 / Total 22 pages 0992049096-0 201108265, so in keeping with other materials The overall diameter of the headphone cord can be further reduced under the requirement of constant tensile strength. In addition, the density of the carbon nanotubes is smaller than that of the prior materials, so that the earphone cord having the carbon nanotubes is lighter in weight.
