[0023] As shown in Figure 1 , Figure 3 and Figure 4 , the positioning assembly 4 comprises tooth blocks 401, folding springs 402, adjusting frames 403 and adjusting blocks 404, which are symmetrically arranged, the tooth blocks 401 are arc-shaped, the folding springs 402 are fixedly connected to the back sides of the tooth blocks 401, the adjusting frames 403 are fixedly connected to the back sides of the tooth blocks 401, the inner sides of the adjusting frames 403 are configured with inclined surfaces, and the inclined surfaces of the adjusting blocks 404 are movably connected with the inclined surfaces of the adjusting frames 403, one end of the folding spring 402 away from the tooth block 401 is fixedly connected to the earmuff 1, the adjusting frame 403 and the tooth block 401 are movably connected to the earmuff 1, and one end of the adjusting block 404 away from the adjusting frame 403 is fixedly connected with the inner side of the protective shell 3. The positioning assembly 4 further comprises a positioning ring 405, which is fixedly connected to the inner side of the adjusting ring 2, and the tooth blocks 401 are located on the inner side of the adjusting ring 2 and engaged with the adjusting ring 2.

[0024] The rotation of the adjusting ring 2 can be performed only after the protective shell 3 is pressed inward, so as to avoid the movement of the containing strip 9 caused by accidental touch of the adjusting ring 2. One adjusting ring 2 controls the rotation of one containing strip 9, so as to facilitate the adjustment of the positions of the two containing rings according to the needs of the user, and improve the flexible adjustment capability of the head-mounted sports Bluetooth earphone. The two containing bands are located at different positions of the head of the user, which is beneficial to improve the stability during wearing, avoid ear compression caused by the movement of the earmuff 1 during sports, and reduce the risk of falling of the head-mounted earphone.

[0025] As shown in Figure 1 and Figure 5 , the limiting assembly 10 comprises plug blocks 1001, control strips 1002 and rotating shafts 1003, which are symmetrically arranged, the plug blocks 1001 are fixedly connected with the control strips 1002, the rotating shafts 1003 penetrate through the control strips 1002, and the rotating shafts 1003 are fixedly connected with the control strips 1002, the control strips 1002 are movably connected to the containing strips 9 through the rotating shafts 1003, the limiting strips 8 are configured with one-way teeth, the front ends of the plug blocks 1001 are matched with the one-way teeth of the limiting strips 8, and the control strips 1002 are arc-shaped, the limiting assembly 10 further comprises return springs 1004, which are symmetrically arranged, one end of the return spring 1004 is fixedly connected with the inner side of the control strip 1002, and the other end of the return spring 1004 is fixedly connected with the inner side of the containing strip 9. The outer side of the containing strip 9 can be made of a skin-friendly sweat-absorbing material, which is beneficial to improve the comfort of the user.

[0026] Due to the one-way tooth on the limiting strip 8, and the insertion block 1001 matches the one-way tooth, the containing strip 9 is pressed towards the guide block 7, so that both limiting strips 8 can be shrunk into the inside of the containing strip 9, and vice versa, the containing strip 9 cannot be moved away from the limiting strip 8, only by pressing the outside of the control strip 1002, it rotates around the rotating shaft 1003, so that the return spring 1004 is compressed and shortened, thereby the insertion block 1001 is separated from the one-way tooth of the limiting strip 8, at this time, the extension and contraction state of the containing strip 9 and the limiting strip 8 can be adjusted, so that the tightness of the containing band can be freely adjusted according to the different sizes of the head of the user, and the wearing is more comfortable.

[0027] Working principle: in use, first, press the protective shell 3 inwards, push the two adjusting blocks 404 to move inwards at the same time, the inclined surface of the adjusting block 404 is in movable contact with the inclined surface of the adjusting frame 403, so that the two adjusting frames 403 move close to each other, drive the two tooth blocks 401 to separate from the positioning ring 405, then rotate the adjusting ring 2 on this side without loosening the protective shell 3, drive the guide block 7 to rotate around the ear cover 1 of the adjusting ring 2, drive the limiting strip 8 and the containing strip 9 to rotate, so as to change the included angle between the two containing strips 9, the containing strip 9 one is located on the top of the user's head, the containing strip 9 two is located on the user's chin, or the containing strip 9 one is located on the top of the user's head, and the containing strip 9 two is located at the back of the user's head. Then loosen the protective shell 3, under the action of the folding spring 402, the tooth block 401 re-engages with the positioning ring 405. So as to keep the angle of the containing strip 9 unchanged; due to the one-way tooth on the limiting strip 8, and the insertion block 1001 matches the one-way tooth, the containing strip 9 is pressed towards the guide block 7, so that both limiting strips 8 can be shrunk into the inside of the containing strip 9, and vice versa, the containing strip 9 cannot be moved away from the limiting strip 8, only by pressing the outside of the control strip 1002, it rotates around the rotating shaft 1003, so that the return spring 1004 is compressed and shortened, thereby the insertion block 1001 is separated from the one-way tooth of the limiting strip 8, at this time, the extension and contraction state of the containing strip 9 and the limiting strip 8 can be adjusted.

[0028] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
