[0002] Headphones are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers close to the ears, allowing you to listen to audio alone without disturbing others. They are mostly used in mobile phones, walkmans, radios, portable video games, and digital audio players.

[0003] The ear-hook design of earphones prevents the earphones from being directly inserted into the ear canal, reducing the pressure on the ears caused by long-term wear and improving wearing comfort. At the same time, this design also allows the ears to ventilate and reduce the risk of ear canal infection.

[0004] The existing ear-hanging wire of the earphone is an ordinary shaped steel wire. However, the ear-hanging wire obtained by this structure has the following defects in the actual manufacturing and use process: Solid ordinary shaped steel wire is not conducive to threading and is inconvenient to wrap with rubber, which reduces production efficiency and affects the appearance.

[0009] In one embodiment, the process of making the steel sheet into the steel pipe in step S2 is as follows: S20: Drawing the third steel sheet into a first arc-shaped profile by a tube drawing machine; S21: annealing the first profile; S22: Drawing the first profile into a second arc-shaped profile by a tube drawing machine; S23: Annealing the second profile; the diameter of the second profile is smaller than the diameter of the first profile.

[0012] In one embodiment, during shaping in the muffle furnace in step S31 , the shaping temperature is 800° C. and the shaping time is 25 minutes.

[0013] Compared with the prior art, the present invention has the following advantages: in actual use, the ear hook wire produced by the process of the present invention is C-shaped and has a threading channel, which is convenient for threading, has a good rubber coating effect, and has a beautiful appearance.
