The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0029] Example:

[0030] like Figures 1 to 4 As shown, this utility model provides an adjustable ear shell angle structure for headphones. The overall structure includes a headband strip 11 and an ear shell 12. The headband strip 11 provides basic frame support for the entire headphone, allowing the device to be worn on the user's head and improving the stability of the device. Two sets of mounting brackets 13 are symmetrically installed at both ends of the headband strip 11, and the mounting brackets 13 are provided with a first sliding groove. The device can provide a sliding track for the sliding plate 14 through the first sliding groove, so that the device can adjust the position of the sliding plate 14 and improve the device's ability to adapt to users with different head shapes.

[0031] One end of the sliding plate 14 is provided with a self-locking component for fixing it; the self-locking component includes a sliding rod 15 and two sets of self-locking rods 16. By connecting the two ends of the sliding rod 15 to two sets of first brackets 19 respectively, the sliding rod 15 can be installed on the sliding plate 14; two sets of second sliding grooves are symmetrically opened on the sliding rod 15, and the two sets of self-locking rods 16 are slidably connected to the two sets of second sliding grooves respectively; the device can achieve fine adjustment of the position of the self-locking rod 16 by sliding the self-locking rod 16 in the second sliding groove, so that the device can adjust the fixed state according to actual needs and improve the adaptability of the device in different usage scenarios.

[0032] like Figure 4 As shown, the self-locking component also includes two sets of first springs 17. One end of each set of first springs 17 is connected to one set of self-locking rods 16, and the other end is connected to the sliding rod 15. The first springs 17 provide an automatic reset function for the self-locking rods 16 using their elastic force, making it easier to lock and unlock during use and improving the device's usability. Multiple sets of limiting holes for locking the self-locking rods 16 are provided on both sides of the first sliding groove. Each self-locking rod 16 is equipped with a control plate 18 for adjusting the position and disabling the self-locking function. The device can unlock the self-locking component via the control plate 18, allowing for rapid changes in the fixed position of the sliding plate 14, improving the device's adjustment efficiency and enhancing its ability to meet users' rapid adjustment needs.

[0033] like Figure 3 , Figure 4 As shown, two sets of first brackets 19 are symmetrically installed on the sliding plate 14, and a fixing frame is installed on the first bracket 19. The fixing frame includes two sets of fixing rods 22 and two sets of mounting seats 23. By connecting the two ends of the fixing rods 22 through the two sets of first brackets 19 and the mounting seats 23, the fixing frame can be installed on the first brackets 19, making the device more compact and stable in structure and improving the overall reliability of the device.

[0034] A connecting component for adjusting the angle of the ear shell 12 and increasing wearing comfort is installed between the fixed frame and the ear shell 12. The connecting component includes a rotating part and two sets of telescopic parts. The telescopic parts include a telescopic frame 32 and a sliding frame 31. The telescopic frame 32 is connected to the mounting base 23. A third sliding groove is provided on the telescopic frame 32. The sliding frame 31 is slidably connected to the third sliding groove. Two sets of second springs 24 are installed in the third sliding groove. The second springs 24 enable the sliding frame 31 to slide elastically within the telescopic frame 32, allowing the device to adapt to changes in pressure and position of different users' ears, thus improving the wearing comfort of the device. A limiting frame 28 for limiting the sliding range of the sliding frame 31 is installed on the telescopic frame 32. A first limiting plate 29 is installed on the telescopic frame 32. The device can control the sliding range of the sliding frame 31 through the limiting frame 28 and the first limiting plate 29, so that the device can remain stable during adaptive adjustment.

[0035] The rotating component includes a first rotating frame 25 and a second rotating frame 26. An adaptive adjustment rod 27 is installed between the two sets of sliding frames 31. The first rotating frame 25 is sleeved on the adaptive adjustment rod 27, and the second rotating frame 26 is rotatably connected to the first rotating frame 25. Through the setting of the rotating component, the ear shell 12 can be rotated at multiple angles, so that the device can better fit the contour of the user's ear. The device can further enrich the adjustment angle of the ear shell 12 through the rotational connection of the first rotating frame 25 and the second rotating frame 26, so that the device can meet the personalized needs of different users for the angle of the ear shell 12, improve the personalized adaptation capability of the device, and enhance the device's ability to meet the diverse needs of users.

[0036] like Figure 2 As shown, the mounting frame 13 is equipped with two sets of fixing seats 33 for assisting the mounting frame 13 in mounting onto the headband 11. Second limiting plates 21 are installed at both ends of the mounting frame 13 to limit the displacement distance of the sliding plate 14. The installation of these two sets of auxiliary fixing seats 33 makes it easier to install the mounting frame 13 onto the headband 11, making the assembly of the device more convenient and improving the ease of use during production and assembly. The second limiting plates 21 limit the displacement distance of the sliding plate 14, ensuring that the device remains within a reasonable range during adjustment, thus improving the safety of the device's adjustment and enhancing its ability to ensure structural stability.

[0037] The specific usage and function of this embodiment are as follows:

[0038] First, the mounting bracket 13 is installed onto the headband strip 11; the second limiting plates 21 at both ends of the mounting bracket 13 limit the displacement distance of the sliding plate 14, preventing the sliding plate 14 from sliding excessively and causing structural damage, and ensuring the safety and stability of the headphone adjustment process.

[0039] Next, the user puts on the headphones, with the headband 11 spanning the head to provide basic support for the entire headphones and ensure that the headphones are stably positioned above the head. At this time, the first sliding groove on the mounting bracket 13 begins to function. If the user feels that the position of the earcups 12 needs to be adjusted, the user can operate the sliding plate 14. The self-locking component at one end of the sliding plate 14 is initially locked. When the user presses the control plate 18, the control plate 18 drives the self-locking rod 16 to overcome the elastic force of the first spring 17 and disengage from the limiting holes on both sides of the first sliding groove, releasing the fixation of the sliding plate 14. At this time, the user can slide the sliding plate 14 along the first sliding groove. After adjusting it to a suitable position, the user releases the control plate 18. Under the elastic force of the first spring 17, the self-locking rod 16 re-engages into the corresponding limiting hole, fixing the sliding plate 14. This achieves the front-to-back adjustment of the earcup 12 position to meet the needs of users with different head shapes.

[0040] Next, when the headphones are worn on the head, the ear shell 12 contacts the ear; the ear shell 12 is connected to the fixing frame through the connecting component, and the telescopic component in the connecting component begins to self-adjust; the sliding frame 31 in the telescopic component is in the third sliding groove of the telescopic frame 32 and is subjected to the elastic force of the second spring 24; if the ear applies pressure to the ear shell 12, the sliding frame 31 will slide in the third sliding groove, and the second spring 24 will compress or extend, adapting to the changes in ear pressure and position, so that the ear shell 12 fits the ear better and improves wearing comfort; at the same time, the limiting frame 28 and the first limiting plate 29 limit the sliding range of the sliding frame 31 to ensure that the adjustment is within a safe and reasonable range and to ensure the stability of the headphone structure.

[0041] In addition, the rotating components also play an important role; the first rotating frame 25 is mounted on the adaptive adjustment rod 27, and the second rotating frame 26 is rotatably connected to the first rotating frame 25; when the user's head posture changes or the contact angle between the ear contour and the ear shell is different, the ear shell 12 can adjust the angle through the relative rotation of the first rotating frame 25 and the second rotating frame 26, further conforming to the ear contour, providing a more comfortable wearing experience, and meeting the user's personalized needs for the ear shell angle in different usage scenarios.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
