[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] In such Figures 1 to 2 In the existing headphone structure shown, it can be seen that the headband 100 has a sliding strip 600. When the user uses the headphones, pulling the headphone end rod 500 adjusts the distance between the headphones and the headband 100, thereby adjusting the overall size of the headphones according to the user's head size and improving wearing comfort. However, because headphones need to be... Figure 1 To ensure aesthetic appearance in the initial state shown, the pull joint between the headband 100 and the earphone end rod 500 needs to be smooth. This results in a sharp edge 510 at the original contact point between the headband 100 and the earphone end rod 500 when the earphone is pulled a certain distance away from the headband 100. This edge can easily scratch the hand during use, reducing comfort.

[0033] like Figures 3 to 7 As shown, this utility model embodiment provides a headset, including a headband 100 and two sets of headphone bodies 300.

[0034] The headband 100 has housings 200 at both ends. The housing 200 includes an outer housing 210 and an inner housing 220. The outer housing 210 and the inner housing 220 are interlocked and form a sliding chamber 230 with a long strip track between them. The outer housing 210 has a first groove 211 that communicates with the sliding chamber 230. The inner housing 220 has a second groove 221 that communicates with the sliding chamber 230. Two sets of earphone bodies 300 are respectively disposed at both ends of the headband 100. The earphone body 300 includes an ear cup 310 and a slider 320. The slider 320 is disposed on the outside of the ear cup 310. The slider 320 includes a column 321 and protruding rods 322 disposed on both sides of the column 321. The two ends of the column 321 are slidably engaged with the first groove 211 and the second groove 221, respectively. The protruding rods 322 are located in the middle of the length direction of the slider 320 and are slidably disposed in the sliding chamber 230.

[0035] It is understandable that the design of the shells 200 at both ends of the headband 100, and the cooperation between the sliding chamber 230 and the slider 320, allows the headphone body 300 to be adjusted along the sliding chamber 230. Users can flexibly adjust the wearing position of the headphones according to their head shape and ear position, thereby obtaining a more fitting and comfortable wearing experience. The sliding cooperation between the column 321 of the slider 320 and the first sliding groove 211 and the second sliding groove 221, as well as the sliding setting of the protrusion 322 in the sliding chamber 230, forms a stable mechanical structure, ensuring that the headphones will not easily shake or fall off during use, thus improving the wearing stability of the headphones. Since this utility model does not require a pull-out structure to adjust the position of the headphone body 300 like the structure in the prior art, there is no sharp edge 510, which can improve the user's comfort.

[0036] like Figure 5 and Figure 6 As shown, in one embodiment of this utility model, the cross-section of the column 321 is square. Compared with a circle or other shapes, the square cross-section design of the column 321 can provide better torsional resistance and structural strength, making the slider 320 more stable during sliding and less prone to deformation or damage. The bottom of the protrusion 322 is connected to the column 321. The two protrusions 322 are mirror images of the column 321 and have a certain angle of inclination that expands away from the column 321. The protrusions 322 can be inserted into the sliding chamber 230 after slight elastic deformation, so that the contact between the protrusions 322 and the inner wall of the sliding chamber 230 can have a certain interaction force, preventing the slider 320 from loosening during sliding.

[0037] like Figures 3 to 6As shown, in one embodiment of this utility model, the column 321 has a handle 330 at the end away from the earcup 310. The handle 330 is disc-shaped and its outer diameter is larger than the width of the first sliding groove 211. When the user adjusts the position of the headphone body 300 relative to the headband 100, the handle 330 can be moved. The handle 330 provides a convenient operating point for the user, allowing the user to easily slide the slider 320 up and down using the handle 330, thereby quickly adjusting the wearing position of the headphones and improving ease of use.

[0038] like Figures 3 to 6 As shown, in one embodiment of this utility model, the outer surface of the handle 330 is provided with an anti-slip texture 331. The anti-slip texture 331 can increase the friction for the user during operation, so that even in environments where the hands are sweaty or wet, the user can steadily push the handle 330 to operate, avoiding operational errors due to slipping hands, and further improving the user's experience when using headphones.

[0039] like Figure 7 As shown, in one embodiment of this utility model, the inner surface of the outer shell 210 has wavy inner walls 212 on both sides, and the end of the protruding rod 322 has an arc-shaped fitting part 323. The arc-shaped fitting part 323 abuts against the wavy inner wall 212, so that when the slider 320 is slidable, the arc-shaped fitting part 323 can be inserted into one of the wave grooves of the wavy inner wall 212 to determine the end position of the slider 320, so that the slider 320 will not easily move after being adjusted to the correct position.

[0040] like Figure 5 As shown, in one embodiment of this utility model, the inner shell 220 is provided with two limiting posts 222 protruding inward. The ends of the limiting posts 222 abut against the inner surface of the outer shell 210. The wire 400 passes through the headband 100 and connects to the inside of the earcup 310 through the area between the two limiting posts 222. The two limiting posts 222 can provide a limit for the wire 400, preventing the wire 400 from being misaligned during the movement of the headphone body 300 driven by the slider 320.

[0041] like Figure 3 , Figure 4 and Figure 7 As shown, in one embodiment of this utility model, the headband 100 and the shell 200 are hinged together by a hinge portion 240, and the two sets of earphone bodies 300 can be folded inward relative to the headband 100 for storage. This folding structure significantly reduces the space occupied by the earphones when not in use, making it convenient for users to carry them in backpacks, pockets, etc., thus improving the portability of the earphones.

[0042] like Figure 6As shown, in one embodiment of the present invention, a snap-fit ​​portion 340 is provided at one end of the column 321 near the headphone body 300. The outer diameter of the snap-fit ​​portion 340 is larger than the outer diameter of the column. The column is snapped into the headphone body 300 through the snap-fit ​​portion 340, so that the column 321 and the headphone body 300 can achieve a firm snap-fit ​​engagement.

[0043] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
