[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This anti-loss headset features an elastic cord and a threaded tube structure. Users can connect the threaded tube and locking sleeve in a spiral, forming a loop. The threaded tube and locking sleeve are securely attached to the underside of the neck, preventing the headset from slipping off the head. The elastic cord can be pulled freely, allowing users to adjust its tension as needed.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figure 1 , Figure 3 , Figure 4 as well as Figure 5 As shown, an anti-loss headset includes a first headband 1, a connecting frame 3 fixedly connected to one side of the headset body 2, a sliding rod 12 movably connected inside the connecting frame 3, anti-slip caps 11 welded to both ends of the sliding rod 12, a connecting ring 8 movably connected to the outer wall of the sliding rod 12, an elastic cord 4 fixedly connected to one side of the connecting ring 8, a connecting tube 6 fixedly connected to the other end of the elastic cord 4, a threaded tube 9 movably connected to one end of a set of connecting tubes 6, a circular hole provided inside the threaded tube 9, a ring provided between the connecting tube 6 and the threaded tube 9, the diameter of the ring being larger than the diameter of the hole in the threaded tube 9, a locking sleeve 5 fixedly connected to one end of another set of connecting tubes 6, and the locking sleeve 5 and the threaded tube 9 being threadedly connected.

[0023] With the elastic cord 4 and threaded tube 9, the user can connect the threaded tube 9 and the locking sleeve 5 in a spiral, so that the earphone can form a loop. The threaded tube 9 and the locking sleeve 5 can be fixedly connected to the lower side of the neck to prevent the earphone from slipping off the head. At the same time, the elastic cord 4 can be pulled freely, and the user can adjust the tension of the elastic cord 4 according to the actual situation.

[0024] Example 2, as Figure 1 as well as Figure 2 As shown, a type of anti-loss headphone has an extension frame 7 fitted on the outer wall of a first headband 1. A second headband 10 is detachably connected inside the extension frame 7. Screw holes 13 are provided inside the first headband 1, the second headband 10, and the extension frame 7. A bolt 14 is detachably connected to the upper end of the extension frame 7. The headphone body 2 is provided at the lower end of the first headband 1 and the second headband 10.

[0025] With the structure of the second headband 10 and the extension frame 7, the user can adjust the position of the first headband 1 and the second headband 10 inside the extension frame 7 according to the hole position of the screw hole 13, so that the user can adjust the length of the second headband 10 and the first headband 1 according to their own situation.

[0026] It should be noted that this utility model is a type of anti-loss headphone. When in use, the user aligns the screw holes 13 inside the first headband 1 and the second headband 10 with the screw holes 13 inside the extension frame 7 according to their own situation, thereby adjusting the length of the first headband 1 and the second headband 10 on the outside, and then fixes them with bolts 14. After the user puts on the headphones, the threaded tube 9 and the locking sleeve 5 are screwed on, so that the elastic cord 4 can be wrapped around the front of the user's chest. On the one hand, the user can wrap the elastic cord 4 around the backpack strap to prevent the headphones from slipping off, and on the other hand, the user can hang the elastic cord 4 directly in front of the chest so that the headphones will not slip off from the back of the head.
