Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A noise-canceling headphone includes a headphone frame 1, a connecting frame 2 hinged to the lower end of the headphone frame 1, an earcup 3 hinged inside the connecting frame 2, an elastic frame 4 slidably connected inside the headphone frame 1, an elastic mechanism 5 provided inside the headphone frame 1, a hexagonal shaft 7 fixedly connected to the outside of the connecting shaft of the earcup 3, a drive tube 8 slidably connected to the outside of the hexagonal shaft 7, a positioning cover 9 fixedly connected to the outside of the drive tube 8, a plurality of evenly distributed positioning blocks 10 fixedly connected to the outside of the positioning cover 9, a positioning ring 11 fixedly connected to the outside of the connecting frame 2, and a spring 12 provided on the outside of the hexagonal shaft 7.

[0022] Please see Figure 1-5 A stop 6 is fixedly connected to the outside of the connecting frame 2. The stop 6 contacts the headphone frame 1. The stop 6 can position the deflection range of the connecting frame 2. The positioning block 10 is slidably connected to the groove of the positioning ring 11. The positioning block 10 and the positioning cover 9 are an integral structure. The positioning ring 11 can position the positioning cover 9 through the positioning block 10. The positioning cover 9 contacts the positioning ring 11. The drive tube 8 contacts the ear cup 3. The drive tube 8 can drive the positioning cover 9 to move. One end of the spring 12 is fixedly connected to the drive tube 8. The other end of the spring 12 is fixedly connected to the hexagonal shaft 7. The spring 12 can support the drive tube 8 through its elastic force.

[0023] Please see Figure 1-5The elastic mechanism 5 includes a fixed cover 51. The fixed cover 51 is fixedly connected to the outer side of the earphone frame 1. Multiple evenly distributed steel wires 52 are fixedly connected to the lower end of the elastic frame 4. A baffle 53 is fixedly connected to the lower end of the steel wires 52. A second spring 54 is provided on the outer side of the steel wires 52. The baffle 53 is slidably connected to the fixed cover 51. The elastic frame 4 is in contact with the fixed cover 51. The steel wires 52 can deform. One end of the second spring 54 is fixedly connected to the fixed cover 51. The other end of the second spring 54 is fixedly connected to the baffle 53. The steel wires 52 are slidably connected to the fixed cover 51. The second spring 54 can support the baffle 53 through its elastic force.

[0024] The specific implementation process of this utility model is as follows: When in use, pull the positioning cover 9, the positioning cover 9 drives the drive tube 8 and the positioning block 10 to move, the drive tube 8 compresses the spring 12, when the positioning block 10 disengages from the groove of the positioning ring 11, the positioning of the hexagonal shaft 7 and the earcup 3 can be released, and then the earcup 3 is rotated. During the rotation of the earcup 3, the usage angle can be adjusted. After the adjustment is completed, release the positioning cover 9, the spring 12 returns to its original position, and the spring 12 can drive the positioning block 10 on the outside of the positioning cover 9 to slide into the groove of the adjusted positioning ring 11 through the elastic force, so as to complete the angle locking of the earcup 3.

[0025] After adjusting the angle of the earcups 3, wear the headphone frame 1 on the outside of your head. During the wearing process, your head pushes the elastic frame 4. As the elastic frame 4 moves, it can drive the steel wire 52 and the baffle 53 to move. As the baffle 53 moves, it can compress the second spring 54. After the second spring 54 is compressed, it generates elasticity, which can wrap around the head, thereby effectively increasing the strength of the wrap around the head and improving the stability of wearing.
