[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-4 The utility model provides a technical solution: an easy-to-wear headset, comprising a memory wire 1, one end of the memory wire 1 being rotatably connected to a shaft housing 3 via an axial connection assembly 2, the axial connection assembly 2 comprising a vertical shaft 21, a limiting shaft 22 and a vertical screw 23, wherein the vertical shaft 21 is laser welded to one end of the memory wire 1, and the other end of the memory wire 1 is laser welded to a limiting post 11, so that the soft rubber bag 6 is limited between the limiting post 11 and the vertical shaft 21, and the vertical screw 23 passes through the limiting shaft 22 and is threadedly connected to the vertical shaft 21;

[0027] Specifically, the function of the limiting column 11 is to limit the position of the soft rubber bag 6 together with the vertical rotating shaft 21 to ensure that it is fixed between the two. The soft rubber bag 6 not only increases the wearing comfort, but also protects the memory wire 1 from rust. The vertical screw 23, the limiting convex ring 31 and the vertical rotating shaft 21 can cooperate to provide support and positioning effects, so that the vertical rotating shaft 21 and the limiting shaft 22 are assembled into an integrated structure.

[0028] Furthermore, a limiting convex ring 31 is fixed to the inner wall of the shaft housing 3, an extension column 24 is fixed to one side of the limiting shaft 22, and one end of the extension column 24 passes through the limiting convex ring 31 and is fixed with a limiting block 25. A limiting groove 26 is provided on the end surface of the vertical shaft 21 away from the memory wire 1, and the limiting block 25 is adapted to the limiting groove 26;

[0029] Specifically, the limiting groove 26 is a non-circular structure, and the limiting block 25 is adapted to the limiting groove 26 , which can prevent the vertical shaft 21 and the limiting block 25 from rotating relative to each other, and can prevent the vertical shaft 21 from rotating unnecessarily in the shaft housing 3 .

[0030] Furthermore, a limit ring groove 27 is formed on the outer side of the vertical rotating shaft 21, and an axial sealing ring 28 is sleeved on the outer side of the limit ring groove 27. The axial sealing ring 28 is clamped and limited between the limit ring groove 27 and the inner wall of the rotating shaft housing 3;

[0031] Specifically, the limiting ring groove 27 can ensure that the axial sealing ring 28 can be correctly installed on the vertical rotating shaft 21. The axial sealing ring 28 can provide a rotational damping feeling, thereby improving the user experience.

[0032] Furthermore, the shaft housing 3 is rotatably connected to the earphone housing 5 via a transverse connecting assembly 4. The transverse connecting assembly 4 includes a horizontal shaft 41, a retaining ring 42, and a transverse screw 43. The horizontal shaft 41 is embedded in the passage opening 52. A retaining ring 44 is provided on the outer side of one end of the horizontal shaft 41 located outside the earphone housing 5. A ring groove 45 is provided on the outer side of one end of the horizontal shaft 41 located inside the earphone housing 5. The retaining ring 42 is nested on the outer side of the ring groove 45. The transverse screw 43 passes through the horizontal shaft 41 and extends into the shaft housing 3.

[0033] Specifically, the retaining ring 44 can protect the horizontal rotating shaft 41 and prevent dust and impurities from entering the gap of the rotating structure. At the same time, it can prevent the horizontal rotating shaft 41 from entering the earphone shell 5. The retaining ring 42 is embedded in the ring groove 45 to prevent the horizontal rotating shaft 41 from sliding out of the earphone shell 5. The horizontal rotating shaft 41 and the channel opening 52 can be assembled into one, and the structure is stable, which can prevent loosening due to vibration or impact during use.

[0034] Furthermore, the transverse connecting assembly 4 further includes a latch 46 embedded in the end of the shaft housing 3. A hole 32 is formed on one side of the shaft housing 3 corresponding to the transverse screw 43. A notch 47 is formed on the side of the latch 46 facing the hole 32, which is adapted to the end structure of the horizontal shaft 41. The notch 47 is provided with a screw hole that can be threadedly connected to the transverse screw 43.

[0035] Specifically, the function of the latch 46 is to adapt to the end structure of the horizontal rotating shaft 41 to ensure the correct connection and fit between the two, and to form a "T"-shaped limiting structure. The opening 32 allows the transverse screw 43 to pass through, and then be threadedly connected with the notch 47 of the latch 46 to prevent the "T"-shaped limiting structure from loosening, and the notch 47 is a non-circular structure.

[0036] Furthermore, a belt groove 48 is formed on the outer side of the portion of the horizontal rotating shaft 41 located inside the passage opening 52.

The horizontal sealing ring 49 is clamped and limited between the belt groove 48 and the inner wall of the passage opening 52.

[0037] Specifically, the belt groove 48 is designed to limit the horizontal sealing ring 49, which can provide a rotational damping feeling for the horizontal shaft 41, thereby increasing the tactile experience of the user when wearing the earphones. The horizontal sealing ring 49 also has a sealing effect, which can prevent the earphone shell 5 from getting water or moisture.

[0038] Furthermore, the outer side of the memory wire 1 is coated with a soft rubber coating 6. A through groove 51 is provided in the middle of the earphone shell 5. A passage opening 52 is provided on the inner wall of the through groove 51. An upper shell cover 53 and a lower shell cover 54 are respectively inserted into the two sides of the through groove 51. A side of the upper shell cover 53 and the lower shell cover 54 facing the passage opening 52 is provided with an avoidance groove 55.

[0039] Specifically, the upper shell cover 53 and the lower shell cover 54 fit very tightly with the through groove 51, which can ensure the stability and sealing of the structure. The internal electronic components of the earphones are installed between the upper shell cover 53 and the lower shell cover 54.
