[0031] The present application is further described in detail below through drawings and examples.

[0032] Reference Figures 1 to 5 The embodiment of the present application provides an anti-breakage wired headset, including a shell assembly 1, a third shell 2, a wire 3, a speaker 4, and a metal head 5. One end of the wire 3 is fixedly installed with a fixing seat 14, and the other end is fixedly installed with a threaded seat 6 that is threadedly matched with the third shell 2. A plurality of first elastic metal wires 7 for preventing the wire 3 from bending are installed in the wire 3, four elastic strips 8 are fixedly installed in the shell assembly 1, a first rubber ring 9 is fixedly installed at the bottom of the shell assembly 1, and a plurality of second elastic metal wires 13 for preventing the wire 3 from bending are fixedly installed in the first rubber ring 9, and a second rubber ring 10 is fixedly installed on the inner side of the top of the third shell 2.

[0033] Reference Figures 1 to 5 In one aspect of the present embodiment, the housing assembly 1 includes a first housing 11 and a second housing 12 that are fixedly connected to each other. The first housing 11 is fixedly connected to the speaker 4. A first through hole for electrically connecting the wire 3 to the speaker 4 is provided on the first housing 11, and a second through hole is provided on the lower side of the first through hole.

[0034] In this embodiment, the current passes through the metal head 5 and the wire 3 in sequence and finally flows into the speaker 4, and then the speaker 4 starts to work. The opening of the first through hole facilitates the electrical connection between the wire 3 and the speaker 4.

[0035] Reference Figures 1 to 5 In one aspect of the present embodiment, a second inclination angle that matches the first inclination angle is provided on the top circumferential side of the fixing seat 14, the fixing seat 14 is slidably arranged between the four elastic strips 8, the bottom of the fixing seat 14 is a cylindrical structure, the first rubber ring 9 and the second rubber ring 10 are respectively sleeved on the two ends of the wire 3, the wire 3 is electrically connected to the metal head 5, the third shell 2 is fixedly connected to the metal head 5, and a threaded hole 6 that is threadedly arranged to match the threaded seat 6 is provided on the inner side wall of the third shell 2.

[0036] In this embodiment, the first inclination angle and the second inclination angle are provided to facilitate the fixing seat 14 to push the elastic strip 8 to deform and move.

[0037] Reference Figures 1 to 5 In one aspect of the present embodiment, the wire 3 is electrically connected to the metal head 5, the third shell 2 is fixedly connected to the metal head 5, a threaded hole 6 threadedly matched with the threaded seat 6 is provided on the inner side wall of the third shell 2, a plurality of first elastic metal wires 7 are evenly distributed in the wire 3, and an external thread is provided on the peripheral side of the threaded seat 6.

[0038] In this embodiment, the threaded hole 6 is provided to facilitate the threaded fit between the threaded seat 6 and the third housing 2 .

[0039] Working principle: When taking the shell assembly 1 and the third shell 2, generally when the third shell 2 and the shell assembly 1 are separated from the support, one end of the wire 3 is in a vertical state and the other end is on the support, and the top of the wire 3 is in a bent state. When the shell assembly 1 and the third shell 2 are taken out repeatedly for a long time, the end of the wire 3 close to the shell assembly 1 and the third shell 2 is prone to bending and damage. However, in this application, when the wire 3 is bent, the first elastic metal wire 7 and the second elastic metal wire 13 support the wire 3 that is about to be bent, so that the bending curvature of the wire 3 is large. When the bending curvature of the wire 3 increases, the wire 3 is not easy to be broken and damaged.

[0040] When the wire 3 is close to one end of the shell assembly 1 and the third shell 2 and is damaged due to long-term bending, the top of the wire 3 is pushed to slide upward, and the fixing seat 14 slides between the four elastic strips 8. The four elastic strips 8 are squeezed by the fixing seat 14 and slide away from each other. When the fixing seat 14 is located at the top of the shell assembly 1, the bent end of the damaged wire enters the shell assembly 1, and then the threaded seat 6 is rotated. The rotation of the threaded seat 6 drives the wire 3 to rotate. After the bottom of the wire 3 rotates, the threaded seat 6 enters the interior of the third shell 2. At this time, the end of the wire 3 close to the third shell 2 is protected by the third shell 2, because the third shell 2 and the shell assembly 1 protect the damaged wire 3, so that the section of the wire 3 is not easily damaged by the bending of the wire 3, thereby extending the life of the headset.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
