[0019] A type of over-ear Bluetooth noise-canceling headphone with easily detachable earcups, such as Figures 1-4As shown, the device includes a mounting bracket 1, a first connecting plate 2, a second connecting plate 3, an earphone shell 6, earcups 7, a sealing strip 10, a second fixing plate 11, a fixing rod 12, a third fixing plate 13, a fixing assembly, and a limiting assembly. The mounting bracket 1 has the first connecting plate 2 connected to both its left and right sides via a damped sliding mechanism. The lower parts of the first connecting plate 2 are rotatably connected to two second connecting plates 3, one in front and one behind. The lower part of the rear second connecting plate 3 is engaged with the earphone shell 6. The earphone shell 6 has four U-shaped grooves on its inner side for easy movement. The sides of the earphone shell 6 that are close to each other are rotatably engaged with the second fixing plate 1. 1. Earmuffs 7 are connected to the sides of the second fixing plates 11 that are close to each other. Sealing strips 10 are connected to the earphone shells 6. The sealing strips 10 are snapped into the adjacent earmuffs 7. Four fixing rods 12 are connected to the inner side of the second fixing plates 11. The fixing rods 12 are rotatably snapped into the adjacent earphone shells 6. The fixing rods 12 are evenly distributed with the adjacent earphone shells 6. A third fixing plate 13 is connected to the fixing rods 12. The lower part of the second connecting plate 3 at the front is provided with fixing components for fixing the earphone shells 6. The earphone shells 6 are provided with limiting components for limiting the earmuffs 7.

[0020] like Figure 1 and Figure 2 As shown, the fixing assembly includes a connecting rod 5, a first fixing plate 8, and a first spring 9. The lower part of the front second connecting plate 3 is slidably connected to the connecting rod 5. The connecting rod 5 is engaged with the earphone shell 6 on the same side. The rear part of the connecting rod 5 is connected to the first fixing plate 8. The first fixing plate 8 is slidably connected to the adjacent second connecting plate 3. The first fixing plate 8 is connected to the adjacent second connecting plate 3 with the first spring 9. It also includes a pull ring 4. The front part of the connecting rod 5 is connected to the pull ring 4, which makes it easy to hold and pull the connecting rod 5 to move.

[0021] like Figure 4 As shown, the limiting assembly includes a third connecting plate 14 and a second spring 15. The third connecting plate 14 is slidably connected to the side of the earphone shell 6 that is far apart from each other. The third connecting plate 14 is in contact with the second fixing plate 11 on the same side. The third connecting plate 14 is connected to the adjacent earphone shell 6 by four second springs 15.

[0022] When using over-ear Bluetooth noise-canceling headphones, this device can be used. First, rotate the second connecting plate 3 to unfold it. Then, lift the earcups 7 and earphone shells 6, causing the second fixing plate 11 to engage with the earphone shell 6. This allows the fixing rod 12 to insert into the U-shaped groove of the earphone shell 6. Simultaneously, the earcups 7 engage with the sealing strip 10 and contact the third connecting plate 14. Pressing the third connecting plate 14 moves the second spring 15, compressing it. The fixing rods 12 are evenly distributed with adjacent earphone shells 6. Next, rotate the earcups 7, causing the second fixing plate 11, fixing rods 12, and third fixing plate 13 to rotate. Releasing the earcups 7 causes the second spring 15 to rebound, and the third connecting plate 14 moves in the opposite direction, pushing the second fixing plate 11 to move, which in turn moves the earcups 7. This causes the fixing rods 12 to move and engage in the U-shaped groove for fixation, further moving the third fixing plate 13. Finally, pull the connecting rods using the pull ring 4. 5. Move the first fixing plate 8, compress the first spring 9, and then snap the earphone shell 6 with the second connecting plate 3. Then release the pull ring 4, the first spring 9 rebounds, and the connecting rod 5 moves back to its original position and snaps with the earphone shell 6 for fixation. This causes the first fixing plate 8 to move back to its original position, and then the earphone shell 6 and earmuff 7 are installed. After installation, pull the earphone shell 6 to move, which drives the earmuff 7 to move, causing the first connecting plate 2 to move along the mounting bracket 1. Then adjust the position of the earmuff 7. After adjusting to a suitable length, put the device on the user's head for use, so that the earmuff 7 contacts the user's ear. The second spring 15 and the third connecting plate 14 provide cushioning. Then connect the device to use the device. This can cushion the earmuff 7 while preventing it from falling off, preventing ear injury, relieving pressure pain, extending service life, and improving comfort and stability. When the earcups 7 need to be disassembled, replaced, or maintained, the connecting rod 5 is moved by the pull ring 4 to disengage from the earphone shell 6, causing the first fixing plate 8 to move and the first spring 9 to be compressed. Then, the earphone shell 6 is removed from the second connecting plate 3. After removing the earphone shell 6, the earcups 7 are removed. The earcups 7 are then pushed to move, causing the second fixing plate 11 to move, which in turn moves the fixing rod 12 along the U-shaped groove, causing the third fixing plate 13 to move. This further compresses the third connecting plate 14, compressing the second spring 15. The earcups 7 are then rotated, causing the second fixing plate 11, fixing rod 12, and third fixing plate 13 to rotate. The earcups 7 are then pulled to move and remove, and the second fixing plate 11, fixing rod 12, and third fixing plate 13 are removed. The second spring 15 rebounds, and the third connecting plate 14 moves back to its original position. The earphone shell 6 or earcups 7 can then be replaced. This allows for quick removal and replacement or cleaning of the earphone shell 6 or earcups 7, facilitating maintenance, reducing repair costs, and providing ease of use.
