In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] The following description, with reference to the accompanying drawings, describes an embodiment of the over-ear headphones 10 of this utility model. (See attached drawings.) Figures 1 to 9 As shown, the over-ear headphones 10 include an earphone unit 300, an adjustment component 100, and a movable component 200. The adjustment component 100 includes a tube 110, a headband 120, and a fixing member 130. The movable component 200 includes a tube 110, an elastic member 210, and a connector 220. Both the adjustment component 100 and the movable component 200 are used to be worn on the human head. The adjustment component 100 adjusts the telescopic length of the over-ear headphones 10 via the headband 120 to fit different head sizes. The movable component 200 adjusts the contact angle between the earphone unit 300 and the human ear via the connector 220 to improve the usability of the over-ear headphones 10.

[0045] In this embodiment, the tube 110 of the adjusting component 100 and the movable component 200 is the same component. One end of the tube 110 defines a movable channel 111 for the movement of the movable part 121 of the headband 120, and the other end defines an adjusting channel 114 for the rotation of the connecting part 221 of the connector 220. In other embodiments, the tube 110 of the adjusting component 100 and the movable component 200 may be different components, and the tube 110 of the adjusting component 100 and the tube 110 of the movable component 200 may be connected to each other so that the adjusting component 100 and the movable component 200 are connected together.

[0046] Specifically, in one example, see Figures 1 to 11As shown, the headband 120 of the adjustment component 100 has an overall ring-shaped structure. Both ends of the headband 120 are connected to tubes 110, allowing both ends of the headband 120 to move within the movable channel 111 of the tubes 110 to adjust the extension length of the headband 120. The headband 120 is then connected to the connector 220 of the movable component 200 via the tubes 110, with the headband 120 and connector 220 located at opposite ends of the tubes 110. The earphone unit 300 is connected to the end of the tubes 110 away from the headband 120 via connector 220; that is, one end of connector 220 is connected to the tubes 110, and the other end is connected to the earphone unit 300. Connector 220 rotates within the adjustment channel 114 of the tubes 110 to change the contact angle between the earphone unit 300 and the human ear.

[0047] In this embodiment of the invention, the headphone 10 moves relative to the tube 110 within the movable channel 111 via the headband 120, changing the distance between the headband 120 and the headphone unit 300. This allows the headphone 10 to fit different head sizes, improving its comfort. Furthermore, the covering of the headband 120 by the fixing member 130 reduces frictional damage to the movable part 121, extending its lifespan. Simultaneously, the headphone 10 connects the headphone unit 300 to the tube 110 via the connector 220. When the headphone 10 shakes, the elastic member 210 secures the connector 220, preventing it from rotating relative to the tube 110. This improves the connection stability between the headphone unit 300 and the tube 110, reducing the possibility of the headphone unit 300 rotating.

[0048] The adjustment assembly 100 of the headset 10 will now be described with reference to the accompanying drawings. It should be noted that the first direction is the direction of movement of the movable part 121. For ease of description and understanding, the left-right direction is used as the first direction in the embodiments and the accompanying drawings, and the up-down direction is used as the second direction. The first and second directions intersect.

[0049] See Figures 2 to 6As shown, the adjustment assembly 100 includes a tube body 110, a headband 120, and a fixing member 130. The tube body 110 internally defines a movable channel 111, which connects to one end of the tube body 110. The headband 120 has a movable portion 121, which is disposed within the movable channel 111 through the end of the tube body 110. The movable portion 121 can move along the path formed by the movable channel 111, thereby changing the relative position of the movable portion 121 and the tube body 110, thus achieving the extension and retraction of the headband 120. The fixing member 130 is connected to the tube body 110, and a portion of the fixing member 130 is disposed within the movable channel 111, abutting against the inner wall of the tube body 110. The fastener 130 has a cavity 131 inside. The cavity 131 is connected to the end of the fastener 130 in the left-right direction and has a mounting port 1311. The movable part 121 can be accommodated in the cavity 131 through the mounting port 1311 so that the fastener 130 covers the movable part 121, thereby avoiding contact between the movable part 121 and the inner wall of the tube 110.

[0050] Specifically, the movable part 121 of the headband 120 is configured to move within the movable channel 111, allowing the headband 120 to enter and exit the movable channel 111, thereby changing the telescopic length of the headband 120. When the movable part 121 moves, it drives the fixing member 130 to move together, ensuring that the fixing member 130 is always positioned between the movable part 121 and the tube body 110. This prevents friction between the movable part 121 and the inner wall of the tube body 110, thus avoiding wear and reducing the service life of the headband 120.

[0051] In related technologies, the headband 120 and the tube 110 are often interference-fitted, allowing the headband 120 to remain stable in its current position after adjustment. However, this can cause the headband 120 to rub against the inner wall of the tube 110 when it slides, resulting in wear. Over time, the connection between the headband 120 and the tube 110 may loosen, causing the tube 110 to sag under gravity when the headband 120 is worn on the head, increasing the extension length of the headband 120 and making it unable to fit the head properly.

[0052] Compared to existing technologies, the adjustment component 100 of this embodiment of the invention, by providing a movable channel 111 inside the tube body 110, allows the headband 120 to move relative to the tube body 110 along the movable channel 111 via the movable part 121, thereby changing the extension length of the headband 120. Furthermore, by covering the movable part 121 with a fixing member 130, contact between the movable part 121 and the inner wall of the tube body 110 can be avoided, thereby reducing friction in the movable part 121 and improving the service life of the headband 120. Simultaneously, by assembling fixing members 130 of different thicknesses, different damping effects can be achieved to produce different adjustment effects.

[0053] In some embodiments, see Figures 2 to 6 As shown, the fastener 130 includes a first part 132 and a second part 133, which are separated in a left-right direction. The first part 132 is connected to the end of the tube 110 facing the headband 120, while the second part 133 is disposed in the movable channel 111 to connect to the end of the movable part 121. Both the first part 132 and the second part 133 have a receiving cavity 131 inside. The first part 132 covers the movable part 121 located at the port of the movable channel 111. The second part 133 covers the end of the movable part 121.

[0054] Specifically, the movable channel 111 connects to the end of the tube body 110, allowing the headband 120 to enter the movable channel 111. The first part 132 is connected to the end of the tube body 110 to cover the movable part 121 located at the end of the tube body 110. When the movable part 121 moves relative to the tube body 110, it moves within the receiving cavity 131 of the first part 132. The first part 132 does not move with the movable part 121, while the second part 133 moves with the movable part 121. By separating the first part 132 and the second part 133, the fixing member 130 can support the movable part 121 at two locations, causing the movable part 121 to be suspended relative to the interior of the tube body 110 (i.e., the fixing member 130 does not contact the inner wall of the tube body 110). Furthermore, as the length of the headband 120 entering the movable channel 111 increases, the movable part 121 tends to bend, and the end of the movable part 121 bends before the middle part. Therefore, by placing the first part 132 at the end of the tube body 110 and the second part 133 connecting the end of the movable part 121, the movable part 121 can be better supported, reducing the possibility of contact between the movable part 121 and the tube body 110.

[0055] Furthermore, in some embodiments, see [reference] Figures 2 to 7 As shown, the receiving cavity 131 of the second part 133 has a mounting hole 1331 formed along the upper and lower direction through the outer wall of the second part 133, and the end of the movable part 121 also has a through hole 122 along the upper and lower direction. When the movable part 121 and the second part 133 are connected and fixed, the positions of the mounting hole 1331 and the through hole 122 correspond to each other, that is, the mounting hole 1331 and the through hole 122 are concentrically arranged. The adjustment assembly 100 also includes a plug-in member 140, which passes through the through hole 122 and the mounting hole 1331 to connect and fix the second part 133 and the movable part 121.

[0056] Specifically, when the movable part 121 moves relative to the tube body 110, the plug-in member 140 also moves along with the movable part 121. The through hole 122 and the mounting hole 1331 are arranged perpendicular to the direction of movement of the movable part 121. This allows the plug-in member 140 to limit the movable part 121 and the second part 133 after passing through the through hole 122 and the mounting hole 1331, preventing the movable part 121 and the second part 133 from shifting due to friction during movement. Furthermore, the plug-in member 140 also enables quick assembly and disassembly of the movable part 121 and the second part 133, improving the ease of use of the adjustment assembly 100.

[0057] Furthermore, in other embodiments, see [reference]. Figure 7 As shown, the movable channel 111 forms a movable groove 112 along the outer wall of the guide tube 110, and the insert 140 is disposed in the movable groove 112. Specifically, the movable groove 112 is disposed in the same direction as the movable channel 111, both being disposed along the axial direction of the tube 110. When the insert 140 passes through the through hole 122 and the mounting hole 1331 to fix the second part 133 and the movable part 121, the end of the insert 140 is disposed in the movable groove 112. When the movable part 121 moves along the movable channel 111, the insert 140 also moves along the movable groove 112. When the movable part 121 moves the plug-in part 140 a certain distance, the plug-in part 140 will abut against the inner wall of the movable groove 112. The movable groove 112 restricts the movement of the plug-in part 140 to prevent the movable part 121 from moving relative to the tube body 110, thereby making the movable part 121 move only along a designated path, thus improving the telescopic adjustment efficiency of the headband 120.

[0058] In some embodiments, see Figure 3 and Figure 6As shown, the first part 132 includes a main body part 1321 and an abutment part 1322 connected to each other. The main body part 1321 is disposed in the movable channel 111 and covers the outer wall of the movable part 121. By accommodating the main body part 1321 within the movable channel 111 to cover the movable part 121, contact friction between the movable part 121 and the inner wall of the tube body 110 can be avoided. Furthermore, the abutment part 1322 is circumferentially disposed on the outer wall of the main body part 1321 and is located on the outer side of the movable channel 111, abutting against the end of the tube body 110 facing the headband 120. By surrounding the outer wall of the main body part 1321, the circumferential area of ​​the abutment part 1322 is larger than the circumferential area of ​​the main body part 1321 and the circumferential area of ​​the tube body 110. When the first part 132 is connected to the tube body 110, the abutment part 1322 is blocked outside the movable channel 111, so that the abutment part 1322 and the end of the tube body 110 abut against each other. When the movable part 121 moves relative to the first part 132, the abutment part 1322 can prevent the first part 132 from moving with the movable part 121 and entering the movable channel 111. This allows the first part 132 to always cover the movable part 121 provided at the end of the tube body 110, avoiding friction between the movable part 121 and the inner wall of the tube body 110.

[0059] In some embodiments, the fastener 130 further includes a telescopic portion disposed between the first part 132 and the second part 133 in a left-right direction, with both ends of the telescopic portion connected to the first part 132 and the second part 133 respectively. Specifically, the telescopic portion has telescopic characteristics. In this embodiment, the telescopic portion is a bellows. In other embodiments, the telescopic portion may also be a telescopic rod or a spring or other component. Since the first part 132 is connected to the tube body 110 and cannot move with the movable part 121, while the second part 133 is disposed at the end of the movable part 121 and moves with the movable part 121, when the movable part 121 moves relative to the tube body 110, the second part 133 will move relative to the first part 132 to stretch or compress the telescopic portion, following the telescopic movement of the headband 120. The telescopic part is covered in the middle part of the movable part 121, thereby preventing the middle part of the movable part 121 from shaking due to the movement of the movable part 121 during movement, thus avoiding friction with the inner wall of the tube body 110, and ensuring the smoothness of the headband 120 adjustment process.

[0060] In other embodiments, see Figures 3 to 6As shown, the adjustment assembly 100 also includes a damping element 150, which is connected to the movable part 121 and disposed between the first part 132 and the second part 133 in a left-right direction. The damping element 150 has a cavity inside, through which the movable part 121 passes. By disposing the damping element 150 between the first part 132 and the second part 133, the damping element 150 can support the middle portion of the movable part 121, thereby preventing the middle portion of the movable part 121 from swaying during movement and thus avoiding contact and friction with the inner wall of the tube body 110. Furthermore, the damping element 150 is disposed in the movable channel 111 and abuts against the inner wall of the movable channel 111. The damping element 150 provides resistance to the movable part 121, reducing its free movement and helping the headband 120 maintain its selected position, thus improving the stability and reliability of the headband 120.

[0061] Specifically, in this embodiment, the damping member 150 and the inner wall of the movable channel 111 are fixedly connected. When the movable part 121 moves relative to the tube body 110, the movable part 121 will move through the cavity of the damping member 150. The damping member 150 provides resistance to the movable part 121, preventing the movable part 121 from moving freely relative to the tube body 110 after being adjusted to a designated position. In other embodiments, the damping member 150 and the outer wall of the movable part 121 are fixedly connected. When the movable part 121 moves relative to the tube body 110, the damping member 150 will move along with the movable part 121. The frictional resistance between the damping member 150 and the inner wall of the tube body 110 keeps the movable part 121 in the selected position, preventing the movable part 121 from moving freely relative to the tube body 110.

[0062] The damping element 150 is made of a material with a high coefficient of friction, such as rubber, silicone, or ceramic. Making the damping element 150 of a high coefficient of friction generates significant frictional resistance to the movable part 121. This ensures that the movable part 121 of the headband 120 can only move relative to the tube 110 when subjected to an external force (such as the pull of a person). Even in its normal state without external force, the damping element 150 still generates frictional resistance to the movable part 121, preventing it from sliding relative to the tube 110. Therefore, when the headphones 10 are in use, the headband 120 and the tube 110 remain in the same connection position and do not automatically change, ensuring that the headphones 10 maintain the same fit to the head for extended periods. Meanwhile, since the headband 120 can slide relative to the tube body 110, when the headphones 10 need to be stored, the movable part 121 can slide along the movable channel 111 so that most of the volume of the headband 120 is contained in the movable channel 111, thereby reducing the overall volume of the headphones 10 for easy storage. Furthermore, the damping element 150 prevents the headband 120 from sliding relative to the tube body 110 on its own, ensuring that the headphones 10 always maintains its size in the stored state, thus improving the user experience.

[0063] In some embodiments, the adjustment assembly 100 further includes a cover 160. The cover 160 is connected to the end of the tube 110 facing the headband 120, and the interior of the cover 160 defines a receiving cavity 161, with the movable channel 111 communicating with the receiving cavity 161. Specifically, a portion of the fastener 130 is disposed outside the movable channel 111, this portion of the fastener 130 being disposed within the receiving cavity 161 of the cover 160, while the remaining portion of the fastener 130 extends into the movable channel 111. This allows the fastener 130 to provide necessary support and stability to the movable portion 121 of the headband 120 without interfering with its movement.

[0064] The cover 160 not only protects the fixing member 130, but also limits the position of the fixing member 130, preventing it from shifting relative to the tube body 110 due to friction with the moving part 121 during movement. This ensures the smooth and reliable operation of the adjustment assembly 100. Furthermore, by accommodating part of the fixing member 130 within the receiving cavity 161 of the cover 160, the adjustment assembly 100 becomes more compact and stable. And because the fixing member 130 can be effectively positioned, it can more precisely operate the moving part 121 of the headband 120, thus improving the user experience.

[0065] In some embodiments, see Figure 7 As shown, the tube body 110 has a curved structure 113. Specifically, the overall structure of the tube body 110 is curved. The curved structure 113 not only makes the headband 120 conform to ergonomic principles and improve wearing comfort, but also enhances the overall aesthetics of the adjustment component 100. At the same time, the curved structure 113 makes the adjustment component 100 fit the head more closely, reducing discomfort caused by prolonged wear.

[0066] The moving component 200 of the headset 10 is described below with reference to the accompanying drawings. See attached diagram. Figures 8 to 12 As shown, the movable component 200 includes a tube 110, an elastic element 210, and a connector 220. An adjustment channel 114 is defined inside the other end of the tube 110. The elastic element 210 is housed in the adjustment channel 114 and connected to the inner wall of the adjustment channel 114 for connection and fixation with the tube 110. The interior of the elastic element 210 is a hollow structure 211, which conducts through both ends of the elastic element 210, allowing the connector 220 to be housed within the hollow structure 211.

[0067] The connector 220 has a connecting portion 221 on the side facing the tube 110. The connecting portion 221 is disposed in the adjustment channel 114 to connect with the hollow structure 211 of the elastic member 210. When the connecting portion 221 is housed in the hollow structure 211, since the volume of the connecting portion 221 is larger than the volume of the hollow structure 211, the elastic member 210 will undergo elastic deformation to increase its circumferential volume. Under the action of external force, the connecting portion 221 can rotate relative to the tube 110 and the elastic member 210 within the hollow structure 211, thereby changing the contact angle between the headphone unit 300 and the human ear.

[0068] Specifically, when the connecting part 221 is disposed within the hollow structure 211, causing the elastic element 210 to deform, within the elastic limit, the elastic element 210 tends to return to its initial shape. Therefore, the elastic element 210 covers the outer wall of the connecting part 221, thereby increasing the friction between them and preventing the connecting part 221 from rotating relative to the tube body 110 and the elastic element 210. Furthermore, when the connecting part 221 rotates within the hollow structure 211, friction occurs between the connecting part 221 and the elastic element 210, causing wear on the connecting part 221. Under the action of elastic potential energy, the elastic element 210 can cover and fix the connecting part 221 according to its shape. Even if the connecting part 221 wears, the elastic element 210 can still adhere to the outer wall of the connecting part 221 to fix the connecting part 221, thereby extending the service life of the connecting part 220.

[0069] In related technologies, when the headphones 10 are removed or shaken due to user movement, the headphone unit 300 deflects relative to the tube 110 and cannot maintain its initial position. This forces the user to rotate the headphone unit 300 to fit the ear, reducing the user experience. In contrast, the movable component 200 of this embodiment, by providing an adjustment channel 114, allows the connector 220 to rotate relative to the tube 110 for adjustment. Furthermore, by connecting the headphone unit 300 to the connecting portion 221 and housing the connecting portion 221 within the hollow structure 211 to deform the elastic member 210, the elastic potential energy of the elastic member 210 is used to fix the connecting portion 221, thereby reducing the deflection of the connector 220 relative to the elastic member 210, improving the connection stability between the connector 220 and the tube 110, and reducing the number of adjustments required for the headphones 10.

[0070] In some embodiments, see Figures 9 to 12 As shown, the movable component 200 also includes a first locking member 230. A fixing hole 2211 is provided on the connecting portion 221, the fixing hole 2211 being open to at least one side of the connecting portion 221. In this embodiment, the fixing hole 2211 is open to both sides of the connecting portion 221. In other embodiments, the fixing hole 2211 may be open to only one side of the connecting portion 221, as long as the fixing hole 2211 can accommodate the first locking member 230. The first locking member 230 is disposed in the fixing hole 2211 to fix the connecting portion 221 within the hollow structure 211 of the elastic member 210.

[0071] Specifically, in one example, see Figures 9 to 12 As shown, the elastic member 210 has a first rotating groove 212, which is arranged circumferentially on a portion of the outer wall of the elastic member 210. The first rotating groove 212 connects to the hollow structure 211. The first rotating groove 212 has groove walls that serve as limiting elements. When the connecting member 220 is fixed to the elastic member 210 by the first locking member 230, a portion of the first locking member 230 is accommodated in the fixing hole 2211, and the end of the first locking member 230 is located in the first rotating groove 212. The groove walls on both sides of the first rotating groove 212 limit the end of the first locking member 230, restricting the movement of the first locking member 230 relative to the elastic member 210, thereby preventing the connecting member 220 and the elastic member 210 from separating.

[0072] When the connecting part 221 rotates relative to the elastic member 210, since the first locking member 230 is connected to the elastic member 210, the first locking member 230 will follow the path of the connecting part 221 to rotate relative to the elastic member 210 along the path of the first rotating groove 212. After the first locking member 230 has rotated through a certain angle, the first locking member 230 will abut against the groove wall in the circumferential direction of the first rotating groove 212. The groove wall will restrict the rotation of the first locking member 230 and thus prevent the connecting part 221 from rotating relative to the elastic member 210. This ensures that the connecting part 220 can only rotate relative to the elastic member 210 within a specified angle, thereby improving the rotation operation accuracy of the connecting part 220 and avoiding damage to the connecting part 220 due to excessive rotation.

[0073] For further details, please refer to [link / reference]. Figure 12 and Figure 13 As shown, the elastic member 210 further includes an extension 213, which is connected to the side of the elastic member 210 facing the connector 220. The connector 220 also includes a second rotating groove 222, which is located on the side of the connector 220 facing the elastic member 210 and is disposed around the partial connecting portion 221, that is, the second rotating groove 222 is circumferentially disposed on the outer wall of the partial connecting portion 221. The second rotating groove 222 corresponds to the extension 213. When the connector 220 and the elastic member 210 are assembled, the extension 213 will be disposed in the second rotating groove 222.

[0074] Specifically, when the connecting portion 221 rotates relative to the tube body 110 and the elastic member 210, the extension portion 213 also rotates within the second rotation groove 222. After the connecting portion 221 has rotated through a certain angle, the extension portion 213 abuts against the groove wall of the second rotation groove 222. By abutting against the second rotation groove 222, the extension portion 213 hinders the rotation of the connecting portion 221 relative to the elastic member 210, thereby further limiting the rotation angle of the connecting portion 221 and improving the rotation operation accuracy of the connecting member 220. Furthermore, by providing the second rotation groove 222, the contact area between the elastic member 210 and the connecting member 220 can be reduced, thereby reducing the friction between the end of the elastic member 210 and the connecting member 220, reducing the wear of the elastic member 210 and the connecting member 220, and extending their service life.

[0075] In some embodiments, see Figure 9As shown, the end of the connecting portion 221 facing the elastic member 210 has an inclined structure 2212. The end of the connecting portion 221 and the sidewall of the connecting portion 221 transition through the inclined structure 2212. Specifically, when the connecting member 220 is assembled to the elastic member 210, it needs to pass through the hollow structure 211 via the connecting portion 221. The inclined structure 2212 facilitates the assembly or disassembly of the connecting portion 221 to the hollow structure 211, allowing the connecting portion 221 to be guided more smoothly into or out of the hollow structure 211 under external force, reducing friction and jamming problems that may occur during assembly and disassembly. Furthermore, by providing the inclined structure 2212, the contact area between the connecting portion 221 and the hollow structure 211 can be reduced. When the connecting portion 221 rotates or moves within the adjustment channel 114, the inclined structure 2212 can effectively reduce frictional resistance, making the operation smoother.

[0076] For further details, please refer to [link / reference]. Figures 9 to 13 As shown, the connector 220 also includes a supporting portion 223, which is connected to the connecting portion 221 and is circumferentially disposed on the outer wall of the connecting portion 221. When the connecting portion 221 is accommodated in the adjustment channel 114, the supporting portion 223 abuts against the end of the tube body 110 facing the connector 220. The supporting portion 223 provides additional support and stability to the connector 220, ensuring that the connector 220 maintains the correct positioning and posture inside the tube body 110. Specifically, when the connector 220 is subjected to external load, the supporting portion 223 can effectively transfer the external load to the tube body 110, avoiding deformation or damage to the connector 220 due to single-point force.

[0077] In this embodiment, the tilting structure 2212 effectively reduces the frictional resistance generated when the connecting part 221 rotates or moves within the adjustment channel 114. When the connecting part 221 rotates, the tilting structure 2212 helps guide the elastic member 210 to produce a more uniform deformation, making the movement of the connecting part 221 within the adjustment channel 114 more stable. The supporting part 223 provides stable support, ensuring that the connecting part 221 does not deviate from its predetermined trajectory during rotation, further reducing friction and wear. The tilting structure 2212 and the connecting part 221 work together to enhance the stability and rigidity of the entire movable assembly 200.

[0078] In some embodiments, see Figure 12 and Figure 13As shown, the hollow structure 211 has an opening 2112 formed on the outer wall of the elastic member 210. The opening 2112 is arranged along the axial direction of the elastic member 210. Specifically, after the connecting part 221 is housed in the hollow structure 211, the elastic member 210 will deform to increase its circumferential volume. By forming the opening 2112 on the outer wall of the elastic member 210, the stress brought to the elastic member 210 by the connecting part 221 after being housed in the hollow structure 211 can be reduced. At the same time, the presence of the opening 2112 changes the overall rigidity distribution of the elastic member 210. When the connecting part 221 acts on the hollow structure 211, the elastic member 210 will produce more obvious local deformation near the opening 2112, which helps to disperse stress concentration points, thereby reducing the risk of material fatigue or damage to the elastic member 210 due to excessive stress.

[0079] In some embodiments, see Figure 13 As shown, the tube body 110 also includes a limiting portion 115, which is housed in the adjustment channel 114 and connected to the inner wall of the tube body 110. The limiting portion 115 extends toward the central axis of the tube body 110, so that the limiting portion 115 protrudes relative to the inner wall of the tube body 110. When the elastic member 210 is connected to the inner wall of the tube body 110, the limiting portion 115 abuts against the end of the elastic member 210 away from the connector 220 to block the elastic member 210.

[0080] Specifically, one end of the tube body 110 defines a movable channel 111, and the other end defines an adjustment channel 114, which are connected. When the connecting part 221 rotates relative to the elastic member 210, the elastic member 210 also tends to rotate relative to the tube body 110 due to the friction between the connecting part 221 and the elastic member 210. The limiting part 115 prevents the elastic member 210 from slipping into the movable channel 111 through the adjustment channel 114 after the connection between the elastic member 210 and the tube body 110 becomes loose, thus avoiding affecting the extension and retraction adjustment of the headband 120. Furthermore, the limiting part 115 facilitates the assembly of the elastic member 210. When the elastic member 210 is installed inside the tube body 110, the limiting part 115 abuts and blocks the elastic member 210, ensuring the accuracy of the installation position of the elastic member 210 and improving the assembly efficiency of the movable component 200.

[0081] For further details, please refer to [link / reference]. Figures 9 to 13As shown, in other embodiments, the tube body 110 and the elastic member 210 are provided with connecting holes 1141. The connecting holes 1141 are formed by the adjustment channel 114 and the hollow structure 211 respectively guiding the elastic member 210 of the tube body 110. The connecting holes 1141 of the tube body 110 and the connecting holes 1141 of the elastic member 210 correspond to each other, that is, when the elastic member 210 and the tube body 110 are assembled, the connecting holes 1141 of the tube body 110 and the connecting holes 1141 of the elastic member 210 are concentrically arranged. The movable component 200 also includes a second locking member 240, which passes through the connecting holes 1141 of the tube body 110 and the elastic member 210 to connect and fix the tube body 110 and the elastic member 210, so as to prevent the elastic member 210 from shifting relative to the tube body 110 under the action of the connecting member 220.

[0082] The extending direction of the limiting part 115 intersects with the setting direction of the connecting hole 1141. For details, please refer to... Figure 13 As shown, when the second locking member 240 passes through the connecting hole 1141, an angle is formed between the second locking member 240 and the limiting part 115. This allows the second locking member 240 and the limiting part 115 to provide additional support and constraint for the elastic member 210 in multiple dimensions. In addition to the axial constraint provided by the limiting part 115 for the elastic member 210, the second locking member 240 can also effectively limit the movement of the elastic member 210 in the direction perpendicular to the connecting hole 1141, thereby enhancing the ability of the movable component 200 to resist lateral forces and reducing the risk of loosening or misalignment caused by external disturbances or accidental impacts during operation.
