In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model relates to a prevent earphone wire rod that splits and endure to warp, including the crust, the inside of crust is provided with first wire, second wire and third prevention bullet silk, the week side bread of first wire inner wall wraps up there is first prevention bullet silk, week side bread of the inner wall of second wire wraps up there is the second prevention bullet silk, the material of first wire and second wire is the copper wire enameled wire. The wire core of the utility model adopts the copper wire enameled wire and wraps the bulletproof wire, thereby not only keeping the diameter of the earphone wire to be minimum, but also being capable of passing various environment tests and hoisting tests, and having outstanding bearing capacity, impact resistance and damping performance; the earphone wire still keeps good elasticity, flexibility and other physical properties at low temperature, can keep the diameter of the earphone wire to be minimum, can pass various environment tests and hanging weight tests, and can still keep the appearance to be complete, not deform and not break even after being impacted.

In particular, the sheath is made of polyurethane.

Specifically, the thickness of the outer skin is 0.15-0.20mm.

Specifically, the diameter of the earphone wire is 1.0mm.

Specifically, the outer surface of the copper wire enameled wire is wrapped with the bulletproof wire.

Preferably, the specification of the bulletproof wire is 200 deniers.

The utility model discloses following beneficial effect has:

the utility model discloses a set up crust, first wire and second wire, and the crust adopts the polyurethane material, bearing capacity, impact resistance and shock-absorbing capacity are outstanding, still keep good elasticity, compliance and other physical properties at low temperature, the sinle silk adopts the copper wire enameled wire and wrap up 200D bullet-proof silk, can keep the diameter of earphone wire minimum, can pass through various environmental test again and hang heavily the test, even receive the impact back in the use, can keep the outward appearance complete, indeformable, do not split.

Of course, it is not necessary for any particular product to achieve all of the above-described advantages at the same time.
