[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a dual-dynamic-coil sound-generating structure for over-ear headphones, including a headband 1, a fixed frame 2 fixedly connected to the side wall of the headband 1, an adjustment component inside the fixed frame 2, an earphone body 3 on the side wall of the fixed frame 2, and a fixed component inside the earphone body 3; the adjustment component includes a connecting plate 4, the side wall of the connecting plate 4 fixedly connected to the side wall of the earphone body 3, a recessed hole 5 inside the connecting plate 4, a sleeve 6 fixedly connected to the side wall of the fixed frame 2, a fixed rod 7 fixedly connected inside the sleeve 6, a locking post 8 slidably connected to the side wall of the fixed rod 7, the side wall of the locking post 8 slidably connected inside the recessed hole 5, a first spring 9 sleeved on the side wall of the fixed rod 7, a lever 10 fixedly connected to the side wall of the locking post 8, the side wall of the lever 10 slidably connected inside the sleeve 6, one end of the first spring 9 fixedly connected inside the sleeve 6, and the other end of the first spring 9 fixedly connected to the side wall of the locking post 8;

[0033] When using this device, when the length of the head beam 1 needs to be adjusted, the lever 10 acts as the starting device for the adjustment action. By moving the lever 10, the user can drive the connected locking post 8 to move. The side wall of the fixing rod 7 provides a sliding track for the locking post 8, ensuring the accuracy of the direction and the smoothness of the movement of the locking post 8. During the sliding process, the locking post 8 will apply pressure to the first spring 9. As an elastic element, the first spring 9 will store elastic potential energy when compressed, providing power support for the subsequent fixing action. The concave hole 5 originally fixes the connecting plate 4 by cooperating with the locking post 8, ensuring that the length of the head beam 1 will not change arbitrarily during normal use. When the locking post 8 is disengaged from the concave hole 5 under the action of the lever 10, This releases the fixed constraint on the connecting plate 4. At this time, the user can pull the headphone body 3 to drive the connected plate 4 to slide inside the fixed frame 2. The fixed frame 2 provides guidance and support for the sliding of the connecting plate 4, allowing the connecting plate 4 to move along a predetermined direction, thereby adjusting the length of the head beam 1. After adjusting the length of the head beam 1, the user releases the lever 10. At this time, the first spring 9 begins to exert its stored elastic potential energy and quickly rebounds. The rebound of the first spring 9 pushes the locking post 8 back into the recessed hole 5, and it once again tightly cooperates with the recessed hole 5 to achieve a firm fixation of the connecting plate 4, so that the adjusted length of the head beam 1 can be maintained, ensuring the stability and reliability of the head beam 1 during subsequent use of the equipment.

[0034] Reference Figure 1 , Figure 3 and Figure 4The fixing component includes an earcup 11, the sidewall of which is slidably connected to the inside of the headphone body 3. A fixing hole 12 is provided inside the earcup 11. A square groove 13 is provided inside the headphone body 3. A limiting block 14 is provided inside the headphone body 3. The sidewall of the limiting block 14 is slidably connected to the inside of the square groove 13. A locking block 15 is fixedly connected to the sidewall of the limiting block 14. The locking block 15 is used to connect the earcup 11 and the headphone body 3. Its cooperation with the fixing hole 12 determines the installation and removal state of the earcup 11. The sidewall of the locking block 15 is slidably connected to the inside of the square groove 13. The sidewall of the locking block 15 is slidably connected to the inside of the fixing hole 12. A second spring 16 is provided inside the headphone body 3. One end of the second spring 16 is fixedly connected to the inside of the square groove 13. The other end of the second spring 16 is fixedly connected to the sidewall of the limiting block 14.

[0035] When the earcups 11 need to be replaced, since the earcups 11 are the parts that directly contact the user's ears, their material and comfort directly affect the user experience. Therefore, replacing the earcups 11 can meet the needs of different users for comfort, hygiene, and other aspects. The user moves the earcups 11 by pulling them. The locking block 15, as the part connecting the earcups 11 and the headphone body 3, determines the installation and removal state of the earcups 11 through its cooperation with the fixing hole 12. When the earcups 11 are pulled, the locking block 15 is squeezed. This squeezing action is caused by the earcups 11 being pulled. The relative positional relationship between the moving direction of 11 and the fixed structure is generated. The square groove 13 provides a space for the locking block 15 to be accommodated when it is squeezed, allowing the locking block 15 to enter it, thereby changing its engagement state with the fixed hole 12. The limiting block 14 mainly plays the role of limiting the displacement direction and degree of the second spring 16, ensuring that when the second spring 16 is squeezed, the direction of the force is along the direction of the locking block 15 disengaging from or engaging with the fixed hole 12, thus ensuring the stability of the entire structure. When the locking block 15 is squeezed into the square groove 13, the second spring 16... The earcups 11 are constrained and compressed by the limiting block 14, storing elastic potential energy. As the locking block 15 enters the square groove 13 under the squeezing action and disengages from the fixing hole 12, the original fixing effect of the locking block 15 and the fixing hole 12 on the earcups 11 is canceled. At this time, the user can remove the earcups 11 from the headphone body 3 and then replace them. During the process of inserting the new earcups 11 into the headphone body 3, the locking block 15 is squeezed again. This is due to the interaction between the new earcups 11 and the fixing structure of the headphone body 3 when they are inserted. The locking block 15 is squeezed into the square groove 13 and squeezes the second spring 16 again. The second spring 16 continues to store elastic potential energy. When the locking block 15 moves to a position parallel to the fixing hole 12 as the earcup 11 is inserted, the second spring 16 quickly rebounds, converting the stored elastic potential energy into kinetic energy to push the locking block 15. Under the action of the rebound force of the second spring 16, the locking block 15 is locked into the fixing hole 12, thereby fixing the earcup 11 again and ensuring that the replaced earcup 11 can be stably installed on the headphone body 3 and perform its function normally.

[0036] Working principle: When using this device, when it is necessary to adjust the length of the head beam 1, the lever 10 is moved to make the locking post 8 slide on the side wall of the fixing rod 7 and squeeze the first spring 9. As the locking post 8 disengages from the concave hole 5, the fixing of the connecting plate 4 is released. At this time, the headphone body 3 is pulled to make the connecting plate 4 slide inside the fixing frame 2 to adjust the length. After adjustment, the lever 10 is released, and the first spring 9 rebounds and locks the locking post 8 into the concave hole 5 to fix the connecting plate 4.

[0037] When the earcup 11 needs to be replaced, pull the earcup 11 to move it. The locking block 15 is squeezed into the square groove 13. The limiting block 14 squeezes the second spring 16. The locking block 15 disengages from the fixing hole 12 and cancels the fixation of the earcup 11. It can be removed and replaced. When the new earcup is inserted into the headphone body 3, the locking block 15 is squeezed into the square groove 13 and squeezes the second spring 16. When the locking block 15 is parallel to the fixing hole 12, the second spring 16 rebounds and locks it in place to fix the earcup 11.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
