Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides an earphone cord with double-deck antistatic structure, includes audio cable 1, first antistatic layer 2 and the antistatic coating 3 of second, and the antistatic coating 3 of audio cable 1 outside fixedly connected with second, the antistatic coating 2 of the 3 outside fixedly connected with of second, has realized double-deck antistatic structure through this setting, carries out antistatic protection to audio cable 1.

The audio cable 1 comprises a connecting layer 101 and core wires 102, the outer side of the connecting layer 101 is fixedly connected with a second anti-static layer, the inner side of the connecting layer 101 is fixedly connected with the core wires 102, the most basic functions of the earphone cable are realized through the arrangement, the number of the core wires 102 is three, the top core wire 102 is a common ground wire, the left core wire 102 is a left sound channel signal wire, the right core wire 102 is a right sound channel signal wire, the audio cable 1 can be shielded and protected through the common ground wire through the arrangement, the first anti-static layer 2 comprises a first rubber layer 202 and a metal woven layer 203, the outer side of the first rubber layer 202 is fixedly connected with the cotton woven layer 201, the surface of the earphone cable is softer through the cotton woven layer 201, the earphone cable has better hand feeling, the inner side of the first rubber layer 202 is fixedly connected with the metal woven layer 203, the earphone cable can be subjected to electrostatic shielding through the metal woven layer 203, and is a, the second antistatic layer 3 includes insulating layer 301 and second rubber layer 302, insulating layer 301 top and 2 fixed connection of first antistatic layer, the inboard and second rubber layer 302 fixed connection of insulating layer 301, the inboard fixedly connected with shielding layer 303 of second rubber layer 302, the inboard and audio frequency line 1 fixed connection of shielding layer 303, can carry out the electrostatic shielding of second time to audio frequency line 1 through this setting, make audio frequency line 1 more be difficult to receive the interference of static.

The working process is as follows: when the earphone cord with the double-anti-static structure is used, firstly, the cotton yarn weaving layer 201 on the outermost layer of the earphone cord can absorb moisture in the air, so that the earphone cord can keep certain moisture, the static can be directly discharged into the air when encountering the static, so that people cannot be stimulated by the static when contacting the earphone cord, meanwhile, because the metal weaving layer 203 has stronger hardness, the earphone cord cannot be too hard when in use, at the moment, the cotton yarn weaving layer 201 with softer texture can ensure that the surface of the earphone cord is softer, the hand feeling of the earphone cord is increased, when the air is drier, the moisture in the cotton yarn weaving layer 201 is evaporated, the static is generated, at the moment, the static can be isolated through the first rubber layer 202, at the moment, partial electric congratulatory messages enter the earphone cord through gaps, when the static contacts the metal weaving layer 203, the metal weaving layer 203 can isolate the static, protect inside audio line 1, most static is isolated outside metal braid 203 this moment, and a small amount of static can enter into shielding layer 303 through metal braid 203, can isolate the interference of electromagnetism to audio line 1 through shielding layer 303, isolates static through second rubber layer 302 and insulating layer 301, makes audio line 1 can not receive the interference of static.
