[0002] Ordinary wires are generally composed of metal wires, but their repeated bending performance is poor and low, which cannot meet the use of some dynamic occasions
For example, Chinese Patent Application No. 200620090447.3 "Stretchable Wires and Cables" and Application No. 86203746 "Elastic Wires and Cables" disclose two kinds of flexible wires, which have in common that the center of the wire is a rubber strip and is wrapped around the rubber strip. The advantage of the above-mentioned conductor composition is that it has a certain degree of flexibility, but metal conductors will inevitably have metal fatigue problems. Once the metal conductor is repeatedly stretched and bent, it will cause the metal conductor to break. Therefore, the above two products will still exist in actual use. The more serious problem of short service life
[0003] At present, the Chinese patent application publication number CN101760001A among the existing patents discloses a thermoplastic elastomer composition for bonding ABS and a preparation method thereof, including 40% to 70% of polyurethane (TPU), 5% to 20% of SEBS %, extender oil 10%-30%, activated calcium carbonate 0-30%, antioxidant 0.1%-0.5%, the prepared thermoplastic elastomer can bond well with ABS and PC materials, and has good shock absorption It has a buffering effect, but it cannot be used on earphone wires, and the defect is obvious

Abstract
The invention relates to the technical field of an earphone line material, and particularly relates to an improved elastic earphone line. The improved elastic earphone line comprises an elastic core line, a conductive layer woven on the surface of the elastic core line, and an elastic insulating protective layer arranged on the surface of the conductive layer in a sleeving manner, wherein the conductive layer is an elastically-telescopic net-shaped pipe woven by a varnished wire; and the elastic core line is prepared from the following components of SEBS, paraffin oil, silicone oil, PP, EPDM, P0E, PE, TPV, calcium carbonate, erucic acid, stabilizer and a stabilizing agent. By filling a co-mixture of PP / filling oil / SEBS with a toughening filler, the plastic is endowed with excellent elasticity; after the plastic is mixed with the paraffin oil for use, a synergistic effect is generated to endow the improved elastic earphone line with excellent elasticity; and in addition, the earphone line product prepared from the elastic core line can be excellent in flexibility and relatively long in extension length, so that the service life and the use effect of the earphone line can be prolonged and improved.
