[0026] The technical solutions in at least one embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. The following description of at least one embodiment is merely illustrative and is not intended to limit this application or its applications. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0027] like Figures 1 to 4As shown, an embodiment of this utility model provides a headset, including a speaker assembly 10, a rear shell assembly 20, and an elastic structure 30. The speaker assembly 10 and the rear shell assembly 20 are movably connected. The speaker assembly 10 has a first arc surface 11, and the rear shell assembly 20 has a second arc surface 21 that mates with the first arc surface 11. The elastic structure 30 is sandwiched between the speaker assembly 10 and the rear shell assembly 20. Under the action of an external force, the speaker assembly 10 can swing relative to the rear shell assembly 20 from its initial position. After the external force disappears, the elastic structure 30 pushes the speaker assembly 10 back to its initial position.

[0028] In this design, an elastic structure 30 is provided between the speaker assembly 10 and the rear shell assembly 20. When the user wears the headphones, they can adjust the headphones according to their individual needs. Under the influence of an external force in contact with the user's ear, the speaker assembly 10 can swing relative to the rear shell assembly 20 from its initial position to achieve the most comfortable state for the user. When the user stops using the headphones, the external force applied to the speaker assembly 10 disappears, and the elastic structure 30 pushes the speaker assembly 10 back to its initial position. With this design, when the user wears the headphones, they can adaptively adjust to the shape of the user's ear to fit the ear as closely as possible, thereby improving the user experience. Therefore, it can accommodate different users, and when the external force disappears, the headphones can automatically return to their initial position for easy reuse next time.

[0029] In this embodiment, the first arc surface 11 is a concave surface with a clearance hole 111. The rear shell assembly 20 includes a rear shell body 22, a connecting post 23, and a pad 24. The second arc surface 21 is a convex surface located on the pad 24. The connecting post 23 passes through the clearance hole 111, and its two ends are connected to the rear shell body 22 and the pad 24, respectively. The speaker assembly 10 and the rear shell body 22 are spaced apart, and the elastic structure 30 is sandwiched between the speaker assembly 10 and the rear shell body 22. Through the cooperation of the clearance hole 111 and the connecting post 23, the speaker assembly 10 is connected to the rear shell assembly 20. The combination of the pad 24 and the elastic structure 30 enables the speaker assembly 10 to swing and return, making the headphones fit the ears better when worn and maintain stability even during exercise. The pad 24 and the elastic structure 30 provide a good cushioning effect.

[0030] In this embodiment, the first arc surface 11 and the second arc surface 21 are both part of a sphere. The rear shell assembly 20 also includes a fastener 25, which passes through the pad 24 and is threadedly connected to the connecting post 23. Designing the first arc surface 11 and the second arc surface 21 as part of a sphere allows for easy angle adjustment of the speaker assembly 10 in different directions. The fastener 25 fixes the pad 24 to the rear shell body 22, preventing the pad 24 from shifting during adjustment of the headset, causing structural wear, and affecting angle adjustment.

[0031] like Figure 3 As shown, the outer wall of the horn assembly 10 has a fitting arc surface 12 protruding towards the rear shell body 22, and the fitting arc surface 12 is opposite to the first arc surface 11; the elastic structure 30 is a ring structure, and the elastic structure 30 is arranged around the connecting post 23, with the inner circumferential surface of the elastic structure 30 engaging with the fitting arc surface 12. The ring structure 30, arranged around the connecting post 23, allows the horn assembly 10 to rotate 360° relative to the rear shell body 22. The elastic structure 30 provides support around the connecting post 23, preventing structural components from bumping against each other and increasing the angle adjustment range; the engagement of the inner circumferential surface of the elastic structure 30 with the fitting arc surface 12 improves the fit between the two and reduces adjustment resistance.

[0032] In this embodiment, the rear shell body 22 has an inwardly recessed avoidance surface 221 on the side facing the speaker assembly 10. The avoidance surface 221 and the adapting arc surface 12 are arranged opposite to each other to avoid the adapting arc surface 12. When the elastic structure 30 is subjected to force, the side of the adapting arc surface 12 moves downward and closer to the rear shell body. The avoidance surface 221 and the adapting arc surface 12 are arranged opposite to each other, which can effectively prevent the speaker assembly 10 from colliding with the rear shell body 22 and extend the service life of the headphones.

[0033] In this embodiment, the elastic structure 30 includes a cylindrical tube 31 and a plate-shaped ring 32. One end of the cylindrical tube 31 abuts against the rear shell body 22, and the other end of the cylindrical tube 31 is connected to the plate-shaped ring 32. The speaker assembly 10 also has a limiting plane 13 surrounding the adapting arc surface 12. The end face of the plate-shaped ring 32 abuts against the limiting plane 13, and the inner circumferential surface of the plate-shaped ring 32 mates with the adapting arc surface 12. The limiting plane 13 can effectively limit the elastic structure 30, preventing the elastic structure 30 from shifting too much when subjected to external force. The inner circumferential surface of the plate-shaped ring 32 mates with the adapting arc surface 12, increasing the contact area with the adapting arc surface 12 and reducing adjustment fluctuations. The cylindrical tube 31 can provide direct elastic support between the rear shell body 22 and the speaker assembly 10, facilitating the angle rotation adjustment of the headset.

[0034] In this embodiment, the elastic structure 30 is an integral structure made of silicone or rubber, and has a Shore hardness of 25-35. This design effectively buffers rotational adjustments, preventing damage to components, and ensures that the elastic structure 30 returns to its original shape when the external force is removed, facilitating personalized readjustment based on the user's needs during the next wear.

[0035] In this embodiment, the rear shell body 22 has an annular groove 222, and the elastic structure 30 is an annular structure, with one end of the elastic structure 30 facing away from the speaker assembly 10 located within the annular groove 222. This arrangement provides stable support for the elastic structure 30 through the annular groove 222, effectively preventing the elastic structure 30 from shifting under external force, reducing interference between internal components, and ensuring the compactness of the headphone structure.

[0036] In this embodiment, the rear shell body 22 has an outer annular rib 223 and an inner annular rib 224, and an annular groove 222 is located between the outer annular rib 223 and the inner annular rib 224. The speaker assembly 10 has a first clearance groove 14, the inner diameter of which is larger than the outer diameter of the outer annular rib 223. The first clearance groove 14 and the outer annular rib 223 are arranged opposite to each other. By providing the first clearance groove 14 and the outer annular rib 223 and arranging them opposite to each other, the rear shell body 22 and the speaker assembly 10 can be fixed in a limited position, ensuring the swing adjustment range of the elastic structure 30 and improving the stability of the headset.

[0037] In this embodiment, the speaker assembly 10 has a second clearance groove 15 on the side facing the rear shell body 22. The inner diameter of the second clearance groove 15 is larger than the outer diameter of the rear shell body 22, and the second clearance groove 15 and the rear shell body 22 are disposed opposite to each other. The provision of the second clearance groove 15 and the rear shell body 22, and their opposite arrangement, improves the stability and aesthetics of the headset.

[0038] like Figure 2 , Figure 3 As shown, the rear shell body 22 includes a rear shell box 225 and a rear shell cover 226, which are fixedly connected, forming an accommodating space between them. The rear shell cover 226 faces the speaker assembly 10, and a connecting post 23 is disposed on the rear shell cover 226. The fixed connection between the rear shell box 225 and the rear shell cover 226 forms a stable accommodating space, providing protection for the internal components. At the same time, the placement of the connecting post 23 ensures the connection between the speaker assembly 10 and the rear shell assembly 20. A pad 24 and an elastic structure 30 can be placed therein, improving the comfort, durability, and reliability of the headphones.

[0039] like Figure 3 , Figure 4As shown, the speaker assembly 10 includes a speaker housing 16, a speaker cover 17, and a speaker 18. The speaker housing 16 and the speaker cover 17 are fixedly connected. The speaker 18 is located in the cavity between the speaker housing 16 and the speaker cover 17. The speaker cover 17 faces the rear shell assembly 20, and a first arc surface 11 is located on the speaker cover 17. The fixed connection between the speaker housing 16 and the speaker cover 17 forms a stable cavity, providing a good sound transmission environment for the speaker 18. At the same time, the setting of the first arc surface 11 ensures the fit and swing adjustment between the speaker assembly 10 and the rear shell assembly 20, improving the comfort and stability of the headphones.
