When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] Please refer to Figures 1 and 2. This application embodiment provides a headset 100, showing perspective views of the headset 100 from different angles. The headset 100 includes a connecting component 10, an earphone component 20, a telescopic component 30, and a folding component 40, wherein the earphone component 20, the telescopic component 30, and the folding component 40 are each in pairs, respectively disposed at both ends of the connecting component 10. Specifically, one end of the connecting component 10, the telescopic component 30, the folding component 40, and the earphone component 20 are connected sequentially; the other end of the connecting component 10 is also arranged in the same way, adopting the same structure, thereby enabling the headset 100 to have left and right audio playback functions. The connecting component 10 is bow-shaped, forming a cavity 10a with the telescopic component 30, thereby allowing the headset 100 to be worn on the user's head. The telescopic component 30 can be extended or shortened to adjust the distance between the two earphone components 20, thereby facilitating the adaptation to different head sizes and improving the applicability of the headset 100. The folding component 40 is rotatably connected to both the headphone component 20 and the telescopic component 30, thereby allowing the headphone component 20 to be rotated and stored within the cavity 10a, thus achieving the folding and storage of the headphone 100.

[0043] Please refer to Figures 1 to 4. In this embodiment, the headset 100 has a used state and a folded state. Figures 1 and 2 show schematic diagrams of the headset 100 in the used state; Figure 3 shows a change state of the headset 100 as it changes from the used state to the folded state. After this change state process, the headset 100 provided in this embodiment can continue to rotate and change to the folded state, as shown in Figure 4. At this time, when the headset 100 is in the folded state, the headphone assembly 20 is folded and stored in the cavity 10a, thereby reducing the size of the headset 100 and making it easier to store.

[0044] In this embodiment, each of the two folding components 40 is provided with a support structure 42. When the headphones 100 are in the folded state, both support structures 42 are located on the side of the folding component 40 away from the connecting component 10. At this time, the two support structures 42 can support the headphones 100 on an object surface, such as a desktop, so that the headphones 100 can stand upright on the object surface, thus occupying a small area and space, so that users do not need to purchase hooks or other items to store the headphones 100. When using them again, simply rotate the headphone component 20 of the headphones 100 from the folded state to the use state to continue using them, which is simple to operate. Of course, the connecting component 10 of the headphones 100 can also be directly hung on a hook for storage.

[0045] Referring to Figures 5 and 6, the headset 100 provided in this embodiment includes a connection component 10 comprising a support member 11 and a protective sleeve 12 sleeved on the outside of the support member 11. The protective sleeve 12 is detachably connected to the support member 11, thereby facilitating the removal of the protective sleeve 12 from the support member 11 for cleaning. The protective sleeve 12 is provided with a detachable unit 13, through which the protective sleeve 12 achieves detachable connection.

[0046] Specifically, referring to Figure 7, the sheath 12 is generally square or rectangular in shape, including a main body 121, a first end 122 and a second end 123 respectively connected to the main body 121, with the first end 122 and the second end 123 located at opposite ends of the main body 121; the detachable unit 13 includes a first connecting unit 131 and a second connecting unit 132, with the first connecting unit 131 located at the first end 122 and the second connecting unit 132 located at the second end 123 or the main body 121, and the first connecting unit 131 and the second connecting unit 132 are detachably connected. The sheath 12 is made of a flexible or elastic material. Specifically, the sheath 12 can be made of cotton, linen, or leather, or other flexible materials. Of course, the sheath 12 can also be made of silicone, as long as it can be wrapped around the support member 11. The sleeve 12 is designed to be detachably rolled up onto the support member 11, allowing it to be removed for cleaning when dust, dirt, or stains are found on it. This enables cleaning of both the inside and outside of the sleeve 12, and it can be reattached to the support member 11 after cleaning, ensuring the sleeve 12 remains clean and aesthetically pleasing, thus improving the user experience. In this embodiment, one of the first connecting unit 131 and the second connecting unit 132 is a buckle, and the other is a slot 33b. Specifically, the first connecting unit 131 and the second connecting unit 132 are two parts of a button that can be interlocked. In other embodiments, the detachable unit 13 can be a magnetic closure, Velcro, or zipper, etc.

[0047] Referring again to Figures 5 and 6, in this embodiment, the telescopic component 30 includes a telescopic member 31 and a connecting shell 32. One end of the telescopic member 31 is connected to the support member 11, and the other end of the telescopic member 31 is connected to the connecting shell 32.

[0048] Please refer to Figures 8 and 9. The support member 11 has a slide rail 111. One end of the telescopic member 31 is located within the slide rail 111 and can move along the slide rail 111, allowing the telescopic component 30 to move closer to or further away from the support member 11. This adjusts the size of the cavity 10a to accommodate different head sizes. In this embodiment, the slide rail 111 also has multiple spaced and connected grooves 112. The telescopic member 31 has a limiting member 311. When the telescopic member 31 moves within the slide rail 111, the limiting member 311 moves sequentially along the multiple grooves 112. After the telescopic length adjustment is complete, the limiting member 311 is located within one of the grooves 112, thus fixing the length adjustment of the telescopic component 30 and preventing length changes due to accidental touches, improving the user experience. To avoid excessive resistance when the limiting member 311 moves within the groove 112, both the groove 112 and the side of the limiting member 311 that abuts are designed with an arc shape. This allows the telescopic component 30 to move within the groove 112 with minimal external force, improving the user experience. To reduce wear, the limiting member 311 and the support member 11 can be made of metal, and the limiting member 311 has a certain degree of elasticity. When the limiting member 311 moves within the groove 112, it emits a clicking sound to alert the user of the change in telescopic length. In this embodiment, the support member 11 has a certain degree of elasticity, allowing the user to move the two headphone components 20 outwards relative to each other to increase the distance between them when wearing the headphones 100, thus facilitating wearing.

[0049] Referring to Figures 5, 6, 8, and 10, a positioning post 33 is fixedly provided on the side of the connecting shell 32 away from the support member 11. The end of the positioning post 33 away from the support member 11 has a mounting cavity 33a. A connecting member 34 is provided within the mounting cavity 33a. The connecting member 34 includes a connecting post 341 and a bearing 342. The bearing 342 has a shaft hole 342a. The axis of the connecting post 341 is perpendicular to the axis of the bearing 342, and the connection between the connecting post 341 and the bearing 342 forms a roughly T-shaped structure. Specifically, the connecting post 341 is installed within the mounting cavity 33a to connect with the positioning post 33. To prevent the connecting post 341 from rotating within the mounting cavity 33a, the positioning post 33 has a slot 33b on the side facing the mounting cavity 33a, and the connecting post 341 has a locking block 343. The slot 33b matches the locking block 343. When the slot 33b is installed in the locking block 343, the connecting post 341 is connected to the positioning post 33 and cannot rotate circumferentially. In this embodiment, the shaft hole 342a penetrates the bearing 342, and each end of the bearing 342 has a limiting groove 342b communicating with the shaft hole 342a. The limiting groove 342b extends axially from the end face of the bearing 342, and has a certain depth in the radial direction of the bearing 342.

[0050] Referring again to Figures 5 and 6, in this embodiment, the folding assembly 40 includes a housing 41, a support structure 42 disposed on the housing 41, and a connector 43 rotatably connected to the shaft hole 342a. The support structure 42 is disposed at one end of the housing 41 near the telescopic assembly 30, and the end of the housing 41 near the telescopic assembly 30 is rotatably connected to the telescopic assembly 30 through the shaft hole 342a and the connector 43. When the housing 41 rotates relative to the telescopic assembly 30, the support structure 42 rotates from a direction generally towards the support member 11 to a direction away from the support member 11. That is, when the headphones 100 are in use, the support structure 42 is generally oriented upwards, and when the headphones 100 are in a folded state, the support structure 42 is oriented downwards, thereby allowing the support structure 42 to be supported on the surface of an object.

[0051] The end of the housing 41 away from the telescopic component 30 is rotatably connected to the headphone component 20, thereby allowing the headphone component 20 to rotate relative to the folding component 40. This allows the headphone component 20 to be folded and stored in the cavity 10a, reducing the volume of the headphone 100.

[0052] Please refer to Figures 11, 12, and 13. The adapter 43 includes a rotating part 431, a limiting cover 432 disposed at one end of the rotating part 431, and a limiting block 433 connected to the rotating part 431. The rotating part 431 passes through the shaft hole 342a, and part of the limiting block 433 is located in the limiting groove 342b and can slide within the limiting groove 342b. The limiting cover 432 abuts against the housing 41, and the housing 41 is provided with a limiting hole 45a. Part of the limiting block 433 is located in the limiting hole 45a, so that when the housing 41 rotates, it can drive the adapter 43 to rotate, thereby causing the folding assembly 40 to rotate relative to the telescopic assembly 30. The setting of the limiting groove 342b allows the limiting block 433 to slide only within the range of the limiting groove 342b, thereby limiting the rotation range of the adapter 43, and thus limiting the rotation angle of the folding component 40 relative to the telescopic component 30, so as to avoid damage to the product components due to excessive rotation angle.

[0053] The housing 41 includes a bottom shell 44 and a top shell 45, with the top shell 45 covering the bottom shell 44. The support structure 42 is located on the bottom shell 44. The top shell 45 has a limiting hole 45a, the shape of which matches the shape of the limiting block 433, ensuring that the limiting block 433 remains relatively stationary and cannot move when it is located within the limiting hole 45a. During assembly, the rotating part 431 of the adapter 43 passes through the limiting hole 45a and then through the shaft hole 342a. The limiting cover 432 is located on the side of the top shell 45 away from the connector 34. The limiting block 433 simultaneously abuts against the wall of the limiting hole 45a and the wall of the limiting groove 342b, meaning the limiting block 433 is simultaneously located within both the limiting groove 342b and the limiting hole 45a. At this time, a portion of the top shell 45 is located between the connector 34 and the limiting cover 432. The housing 41 is provided with a limiting part 411, which abuts against the limiting cover 432, so that when the housing 41 rotates, the limiting part 411 restricts the rotation range of the limiting cover 432.

[0054] Specifically, the limiting part 411 includes a first limiting part 412 disposed on the bottom shell 44 and a second limiting part 413 disposed on the top shell 45. The first limiting part 412 abuts against the side of the limiting cover 432 away from the rotating part 431, and clamps the limiting cover 432 therein with the top shell 45, preventing the limiting cover 432 from moving axially in the rotating part 431. The second limiting part 413 is disposed circumferentially along the limiting cover 432, preventing the limiting cover 432 from moving radially, thereby limiting the rotation and movement range of the adapter 43, thereby allowing the folding assembly 40 to rotate relative to the telescopic assembly 30 within a preset range.

[0055] Referring again to Figures 11, 12, and 13, the housing 41 includes a first connecting portion 414 and a second connecting portion 415. The first connecting portion 414 and the second connecting portion 415 are located at the end of the housing 41 away from the supporting structure 42, and there is a certain distance between them to accommodate part of the headphone assembly 20. The headphone assembly 20 includes opposing through holes 21. The first connecting portion 414 and the second connecting portion 415 are provided with opposing rotating portions 416. The rotating portions 416 are pivots that pass through the through holes 21 and can rotate relative to the through holes 21, thereby allowing the headphone assembly 20 to rotate relative to the folding assembly 40. It can be understood that the front shell 45 and the bottom shell 44 are connected to form the first connecting portion 414 and the second connecting portion 415, facilitating manufacturing and assembly.

[0056] In this embodiment, the support structure 42 is located on the side of the housing 41 away from the first connecting part 414 and the second connecting part 415. With this configuration, when the headphone assembly 20 rotates relative to the folding assembly 40, the folding assembly 40 then rotates relative to the telescopic assembly 30 toward the support member 11. At this time, the headphone assembly 20 is folded and stored in the cavity 10a, and the support structure 42 also rotates to the side away from the support member 11, so that the two support structures 42 can be supported on the surface of the object.

[0057] In this embodiment, the support structure 42 is a plane on the housing 41. Thus, when the headphones 100 are folded and stored, the support structure 42 can have a large contact area with an object surface, such as a desktop, thereby supporting the headphones 100 to be stably placed vertically on the object surface, reducing the desktop area and storage space occupied, and making the desktop neat and orderly. In other embodiments, the support structure 42 can also be other structures, such as two or more oppositely arranged protrusions that collectively support and abut against the object surface, allowing the headphones 100 to be placed vertically after folding and storage.

[0058] Additionally, it should be noted that in this embodiment, the size of the cavity 10a is influenced by the design of the support member 11 and the telescopic component 30, as well as by the product's appearance design and the user's head size. Furthermore, the size of the headphone assembly 20 determines whether it can be perfectly housed within the cavity 10a. Therefore, the telescopic component 30 in this embodiment also has another function. When the cavity 10a is relatively small and the headphone assembly 20 is large, if the headphones need to be folded and stored, the headphone assembly 20 cannot be completely folded and stored within the cavity 10a if the telescopic component 30 is not adjusted to adjust the telescopic length to adjust the size of the cavity 10a. In this case, it is necessary to adjust the telescopic component 30 to increase the size of the cavity 10a, that is, to pull the telescopic member 31 out of the slide 111 by a portion, making the cavity 10a larger so that it can fully accommodate the headphone assembly 20, thus achieving folding and storage. When the cavity 10a is designed to be large, there is no need to adjust the telescopic length of the telescopic component 30, and the headphone component 20 can also be completely folded and stored in the cavity 10a.

[0059] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. The embodiments described above only illustrate several implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
