[0024] There are two sliding arm assemblies 200, which are respectively connected to the two ends of the headband 100.

[0025] There are two ear shell assemblies 300, and the two ear shell assemblies 300 are respectively connected to two sliding arm assemblies 200. The ear shell assembly 300 is used to accommodate the sound generating unit.

[0026] Understandably, when the headband 100 is worn on the user's head, the two ear shell assemblies 300 are positioned at the user's two ears, and the sound emitted by the sound-generating unit within the ear shell assembly 300 propagates towards the user's ears. It should be noted that the sliding arm assembly 200 connects the headband 100 and the ear shell assembly 300. By adjusting the sliding arm assembly 200, the position of the ear shell assembly 300 can be adjusted to accommodate different head shapes.

[0027] Combination Figure 2 and Figure 3 Specifically, the sliding arm assembly 200 includes a guide rail 210 and a sliding arm 220; the guide rail 210 is connected to the headband 100, the sliding arm 220 is slidably disposed on the guide rail 210, and the ear shell assembly 300 is connected to the sliding arm 220.

[0028] Please refer to further details. Figure 5 and Figure 6 More specifically, one end of the guide rail 210 is connected to the headband 100.

By sliding the sliding arm 220, the position of the ear shell assembly 300 can be changed.

[0029] Combination Figure 6 , Figure 7 and Figure 9Furthermore, one end of the sliding arm 220 is positioned towards the headband 100, and the other end is positioned away from the headband 100. The end of the sliding arm 220 away from the headband 100 is provided with a clearance groove 221, and the groove wall of the clearance groove 221 is provided with a blind hole 223. The sliding arm assembly 200 also includes a rotating shaft 230, one end of which is provided with a pin 240. One end of the rotating shaft 230 passes through the clearance groove 221 and the pin 240 is inserted into the blind hole 223. The ear shell assembly 300 is connected to the other end of the rotating shaft 230.

[0030] Combination Figure 4 and Figure 9 It is understandable that the pivot 230 is rotatably connected to the sliding arm 220 by the pin 240, so that the ear shell assembly 300 can rotate relative to the sliding arm 220. Specifically, the axis of the pin 240 is perpendicular to the left and right direction of the headphones and perpendicular to the height direction of the headphones. The ear shell assembly 300 can be folded or unfolded by the pin 240. When the ear shell assembly 300 is folded, it can reduce the space occupied and make it easier to store. When the ear shell assembly 300 is unfolded, the user can use it normally.

[0031] Furthermore, by providing a clearance groove 221 at the end of the sliding arm 220 away from the headband 100, installation space can be provided for one end of the rotating shaft 230. And by providing a blind hole 223 in the groove wall of the clearance groove 221, an installation position can be provided for the pin 240. Additionally, one end of the rotating shaft 230 extends into the clearance groove 221, allowing the pin 240 to be inserted into the blind hole 223, thus concealing the pin 240 and improving its appearance. Moreover, this prevents the pin 240 from being damaged by external impacts, scratches, etc., ensuring the reliability and service life of the product.

[0032] Furthermore, the groove wall of the clearance groove 221 is provided with two blind holes 223 arranged opposite to each other. The two ends of the pin 240 are respectively inserted into the two blind holes 223. The two blind holes 223 are used to limit the two ends of the pin 240, improve the stability of the pin 240, and reduce the risk of the pin 240 falling out of the blind holes 223.

[0033] It should be noted that the axis of the blind hole 223 is perpendicular to the left-right direction of the headphones and perpendicular to the height direction of the headphones. The arrangement direction of the two blind holes 223 is parallel to the axis of the blind holes 223. The two ends of the pin 240 are respectively inserted into the two blind holes 223.

[0034] Combination Figure 9 , Figure 10 and Figure 11Furthermore, the pin 240 includes an outer cylinder 241, an elastic support member 242, and two pin heads 243. The outer cylinder 241 passes through one end of the rotating shaft 230, the elastic support member 242 is disposed inside the outer cylinder 241, and the partial structures of the two pin heads 243 pass through both ends of the outer cylinder 241, and the two pin heads 243 abut against both ends of the elastic support member 242, and the two pin heads 243 are respectively inserted into the two blind holes 223.

[0035] It should be noted that the two pin heads 243 can be brought closer together after being compressed, thereby shortening the overall length of the pin 240. This allows one pin head 243 to be inserted into one blind hole 223 first, and then the other pin 240 to be aligned with the other blind hole 223. The elastic retaining member 242 allows the other pin 240 to return to its original position, thus allowing it to be inserted into the other blind hole 223, achieving the installation of the pin 240. The elastic retaining member 242 can be a spring or a sheet spring.

[0036] Combination Figure 6 and Figure 7 In some embodiments, a first damping ring 270 is provided at the end of the guide rail 210 away from the headband 100. The first damping ring 270 is sleeved on the sliding arm 220 and slides in cooperation with the sliding arm 220.

[0037] Specifically, the first damping ring 270 is fixed to the end of the guide rail 210 away from the headband 100, and the first damping ring 270 is sleeved on the outside of the sliding arm 220. The sliding arm 220 can slide relative to the first damping ring 270. The first damping ring 270 can provide a damping effect when the sliding arm 220 slides relative to the guide rail 210. At the same time, the first damping ring 270 also has a sealing effect, which can reduce the entry of external pollutants between the guide rail 210 and the sliding arm 220 and affect the smoothness of the sliding arm 220.

[0038] The first damping ring 270 can be made of silicone or rubber.

[0039] Furthermore, the guide rail 210 has a card interface 222 at the end away from the headband 100, and the sliding arm assembly 200 also includes a support member 260 sleeved on the sliding arm 220 and engaged with the card interface 222, and a first damping ring 270 is disposed on the support member 260.

[0040] Understandably, the support member 260 is fixed to the end of the guide rail 210 away from the headband 100 by a snap-fit ​​connection, and the support member 260 is used to support the first damping ring 270. It should be noted that the support member 260 is sleeved on the outside of the sliding arm 220, and the sliding arm 220 can slide relative to the support member 260.

[0041] Specifically, the support member 260 includes a support portion 261 and a fastening portion 262 connected to the support portion 261. The support portion 261 is sleeved on the outside of the sliding arm 220 and slides in cooperation with the sliding arm 220. The fastening portion 262 is snapped into the snap-fit ​​interface 222.

[0042] Furthermore, the first damping ring 270 is held between the support portion 261 and the end of the guide rail 210 away from the headband 100. The first damping ring 270 is bidirectionally limited by the support portion 261 and the guide rail 210, which can prevent the first damping ring 270 from loosening and improve reliability.

[0043] Combination Figure 6 and Figure 8 In some embodiments, a second damping ring 280 is provided at one end of the sliding arm 220 near the headband 100, and the second damping ring 280 abuts against and slides against the inner wall of the guide rail 210.

[0044] Specifically, the second damping ring 280 is fixed to the end of the sliding arm 220 near the headband 100, and the second damping ring 280 abuts against the inner wall of the guide rail 210. The second damping ring 280 can slide with the sliding arm 220 relative to the guide rail 210 when the sliding arm 220 slides relative to the guide rail 210. The second damping ring 280 can provide a damping effect when the sliding arm 220 slides relative to the guide rail 210. At the same time, the second damping ring 280 also has a sealing effect, which can reduce the entry of external contaminants between the guide rail 210 and the sliding arm 220, thus reducing the smoothness of the sliding arm 220's movement.

[0045] The second damping ring 280 can be made of silicone or rubber.

[0046] Furthermore, the sliding arm 220 has a slot 224 on the side wall near the headband 100, and the second damping ring 280 is sleeved on the sliding arm 220, with part of the structure of the second damping ring 280 disposed in the slot 224.

[0047] Combination Figure 6 , Figure 7 and Figure 8 In some embodiments, a travel limiter 290 is provided at the end of the sliding arm 220 near the headband 100, and a first damping ring 270 is located on the movement path of the travel limiter 290. It is understood that during the withdrawal of the sliding arm 220, the travel limiter 290 moves with the sliding arm 220. When the travel limiter 290 abuts against the first damping ring 270, it restricts the sliding arm 220 from being further withdrawn, thus limiting the maximum withdrawal stroke of the sliding arm 220 and preventing the sliding arm 220 from detaching from the guide rail 210.

[0048] Specifically, the travel limiter 290 is a screw fixed to the side wall of one end of the sliding arm 220 near the headband 100.

[0049] Combination Figure 5 and Figure 7 In some embodiments, the sliding arm assembly 200 further includes an outer sheath 250, which is fitted over the guide rail 210 and also over the support member 260.

It should be noted that the sliding arm assembly 200 connects the headband 100 and the ear shell assembly 300. By adjusting the sliding arm assembly 200, the position of the ear shell assembly 300 can be adjusted to accommodate different head shapes. Furthermore, the pivot 230 is rotatably connected to the sliding arm 220 via a pin 240, allowing the ear shell assembly 300 to rotate relative to the sliding arm 220. Specifically, the axis of the pin 240 is perpendicular to the left-right direction and the height direction of the headphones. The ear shell assembly 300 can be folded or unfolded using the pin 240. When folded, the ear shell assembly 300 reduces space requirements and facilitates storage; when unfolded, it is ready for normal use. In addition, by providing a clearance groove 221 at the end of the sliding arm 220 away from the headband 100, an installation space can be provided for one end of the rotating shaft 230. Furthermore, by providing a blind hole 223 in the groove wall of the clearance groove 221, an installation position can be provided for the pin 240. In addition, one end of the rotating shaft 230 extends into the clearance groove 221 and the pin 240 is inserted into the blind hole 223. This way, the pin 240 can be hidden, improving the appearance. Moreover, it can prevent the pin 240 from being damaged by external collisions, scratches, etc., ensuring the reliability and service life of the product.
