[0050] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0051] 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.

[0052] The headphones include a headband, earcups, and sliding arms. The sliding arms connect the headband and earcups respectively. Specifically, the sliding arms slide relative to the headband to adjust the tightness of the earcups against the user's face, reducing ear fatigue and discomfort caused by uncomfortable headphone fit. In existing technology, users need to adjust the earcups using the sliding arms every time they wear headphones, making the wearing process cumbersome and unsuitable for users' wearing habits.

[0053] In view of this, the first aspect of this utility model provides an accessory 10, which is used to engage with the headband 20 of a headset 1. It is understood that the headband 20 is located between the two earcups of the headset 1, and both ends of the headband 20 are respectively connected to the two earcups. Referring below... Figures 1 to 11 The following describes accessory 10 according to an embodiment of this application. Specifically, accessory 10 includes a first card block 100 and a second card block 200.

[0054] Reference Figures 1 to 4 First, let's introduce the specific settings for the first block, 100. (Refer to...) Figure 1Regarding orientation, the first locking block 100 can be a locking block on the upper side or the lower side of the accessory 10. This embodiment uses an example where the first locking block 100 is on the upper side of the accessory 10 and the second locking block 200 is on the lower side of the accessory 10. The first locking block 100 is used to cooperate with the second locking block 200 to secure the headband 20. The first locking block 100 includes a first connecting structure 110 and a first fixing part 120 arranged opposite to each other. It can be understood that the first fixing part 120 can be connected to or spaced from the first connecting structure 110.

[0055] Reference Figures 1 to 4 The specific configuration of the second locking block 200 is described below. The second locking block 200 is rotatably connected to the first locking block 100. The second locking block 200 includes a second connecting structure 210 and a second fixing part 220 arranged opposite to each other. The second fixing part 220 can be connected to or spaced apart from the second connecting structure 210. It should be noted that in some embodiments, the structure of the second locking block 200 can be the same as that of the first locking block 100. In other embodiments, the structure of the second locking block 200 can also be different from that of the first locking block 100. This application embodiment uses the example of the second locking block 200 having a different structure from the first locking block 100 for explanation.

[0056] Refer to 1 to Figure 6 The following describes the specific process of fixing accessory 10 to the headband 20 of the headphones 1. Specifically, the second locking block 200 can rotate relative to the first locking block 100 so that the second fixing part 220 can approach the first fixing part 120 to clamp the headband 20, and the second connecting structure 210 can engage with the first connecting structure 110.

[0057] In the technical solution of this utility model, accessory 10 is used to engage with the headband 20 of the headphones 1. Accessory 10 includes a first locking block 100 and a second locking block 200. The first locking block 100 includes a first connecting structure 110 and a first fixing part 120 arranged opposite to each other. The second locking block 200 is rotatably connected to the first locking block 100. The second locking block 200 includes a second connecting structure 210 and a second fixing part 220 arranged opposite to each other. In the prior art, each time a user wears headphones, they need to adjust the tightness of the earcups by sliding the arm. That is, the wearing operation of existing headphones is cumbersome and cannot adapt to the user's wearing habits. In this solution, the second fixing part 220 can be relatively close to the first fixing part 120 to clamp a specific position on the headband 20. That is, the sliding arm can be positioned by accessory 10, so that the user does not need to repeatedly adjust the sliding arm to adjust the tightness of the earcups when wearing them again. Therefore, this solution can make the headphones 1 adapt to the user's wearing habits and improve the user experience.

[0058] Furthermore, the first connecting structure 110 of the first locking block 100 can engage with the second connecting structure 210 of the second locking block 200, thereby enabling the first fixing part 120 and the second fixing part 220 to stably clamp the headband 20, improving the stability of the assembly connection between the accessory 10 and the headphone 1. Moreover, by rotating the second locking block 200 relative to the first locking block 100, the clamping of the headband 20 by the first fixing part 120 and the second fixing part 220 and the engagement of the second connecting structure 210 with the first connecting structure 110 can be achieved, making the assembly connection operation between the accessory 10 and the headphone 1 convenient and quick. In addition, accessories 300 can be provided on the accessory 10, which facilitates user identification and effectively enhances the overall aesthetics of the headphone 1.

[0059] Reference Figures 2 to 6 The specific fixing arrangements of the first fixing part 120 and the second fixing part 220 for the headband 20 are described below. In some embodiments, the first fixing part 120 may be provided with a first groove 121, the opening of which may face the second fixing part 220, and the first groove 121 may be adapted to the structural arrangement of the headband 20. The second fixing part 220 may be provided with a second groove 221, the opening of which may face the first fixing part 120, and the second groove 221 may be adapted to the structural arrangement of the headband 20. Both the first groove 121 and the second groove 221 are used for the headband 20 to pass through. It can be understood that the headband 20 may be arranged through the first groove 121 and the second groove 221. It should be noted that the structure and size of the second groove 221 may be the same as or different from the first groove 121, depending on the actual situation.

[0060] In some embodiments, the first fixing part 120 may be provided with a first groove 121 independently. In other embodiments, the second fixing part 220 may be provided with a second groove 221 independently. This application embodiment is described using the example of the first fixing part 120 having a first groove 121 and the second fixing part 220 having a second groove 221. The accessory 10 of this solution adopts the above-described fixing arrangement, that is, the headband 20 can be clamped by the first groove 121 and the second groove 221, which improves the reliability of the assembly connection between the accessory 10 and the headband 20 and prevents the headband 20 from slipping off during use.

[0061] Reference Figure 1 and Figure 7 The specific fixing structures of the first fixing part 120 and the second fixing part 220 are described below. In some embodiments, the first fixing part 120 includes a first fixing wall 122 and a second fixing wall 123 facing the second fixing part 220. The second fixing part 220 includes a third fixing wall 222 and a fourth fixing wall 223 facing the first fixing part 120. (Refer to...) Figure 1In this embodiment of the application, the fixing wall on the right side of the first fixing part 120 is the first fixing wall 122, the fixing wall on the left side of the first fixing part 120 is the second fixing wall 123, the fixing wall on the right side of the second fixing part 220 is the third fixing wall 222, and the fixing wall on the left side of the second fixing part 220 is the fourth fixing wall 223, as an example.

[0062] It is understood that when accessory 10 is assembled with headband 20, the distance between the first fixing wall 122 and the third fixing wall 222 is less than the distance between the second fixing wall 123 and the fourth fixing wall 223. The gap between the first fixing wall 122 and the third fixing wall 222 is less than the gap between the second fixing wall 123 and the fourth fixing wall 223. Therefore, the first fixing wall 122 can cooperate with the third fixing wall 222 to clamp the thinner part of headband 20, and the second fixing wall 123 can cooperate with the fourth fixing wall 223 to clamp the thicker part of headband 20. The accessory 10 of this solution can adapt to the gradually changing thickness structure of headband 20, further improving the stability and reliability of the assembly connection between accessory 10 and headband 20.

[0063] Reference Figure 1 and Figure 6 The specific fixing configuration of the first fixing part 120 is described below. In some embodiments, the first fixing part 120 is provided with a first gasket 124, which may be disposed on the side of the first fixing part 120 facing the second fixing part 220. The material of the first gasket 124 may be silicone, rubber, or plastic, etc. In this embodiment, silicone is used as an example for the first gasket 124. By adding the first gasket 124, this solution can increase the friction between the first fixing part 120 and the second fixing part 220, prevent the headband 20 from sliding during use, and improve the stability and reliability of the connection between the accessory 10 and the headband 20.

[0064] Reference Figure 1 and Figure 6 The specific fixing configuration of the second fixing part 220 is described below. In some embodiments, the second fixing part 220 is provided with a second gasket 224, which may be disposed on the side of the second fixing part 220 facing the first fixing part 120. The material of the second gasket 224 may be silicone, rubber, or plastic, etc. In this embodiment, silicone is used as an example for the second gasket 224. By adding the second gasket 224, this solution can increase the friction between the first fixing part 120 and the second fixing part 220, prevent the headband 20 from sliding during use, and improve the stability and reliability of the connection between the accessory 10 and the headband 20.

[0065] Reference Figure 3 , Figure 7 and Figure 8The specific fixing arrangements of the first connecting structure 110 and the second connecting structure 210 are described below. In some embodiments, the first connecting structure 110 includes a first protrusion 111, and the second connecting structure 210 includes a first groove 211. The first protrusion 111 can pass through the first groove 211. This solution can effectively improve the stability of the assembly connection between the first connecting structure 110 and the second connecting structure 210, and effectively suppress the relative distance between the first fixing part 120 and the second fixing part 220.

[0066] Reference Figure 3 , Figure 7 and Figure 8 The specific fixing arrangements of the first connecting structure 110 and the second connecting structure 210 are described below. In some embodiments, the first connecting structure 110 includes a second groove 112, which can be arranged adjacent to the first protrusion 111. The second connecting structure 210 includes a second protrusion 212, which can be arranged adjacent to the first groove 211. The second protrusion 212 can pass through the second groove 112. This solution can further improve the stability of the assembly connection between the first connecting structure 110 and the second connecting structure 210, effectively suppressing the relative distance between the first fixing part 120 and the second fixing part 220.

[0067] Reference Figure 4 , Figures 7 to 9 The specific rotational arrangement of the first locking block 100 and the second locking block 200 is described below. In some embodiments, the first locking block 100 includes a rotating part 130, and the second locking block 200 includes a rotating groove 230. The rotating part 130 can be adapted to the rotating groove 230 to allow the first locking block 100 and the second locking block 200 to rotate relative to each other. In other embodiments, the first locking block 100 includes a rotating groove 230, and the second locking block 200 includes a rotating part 130. The rotating part 130 can be arranged through the rotating groove 230 to allow the first locking block 100 and the second locking block 200 to rotate relative to each other. Further, this application embodiment uses the rotating part 130 riveted to the rotating groove 230 as an example for explanation. The rotating part 130 of this solution passing through the rotating groove 230 can improve the stability of the rotational connection between the first locking block 100 and the second locking block 200.

[0068] Reference Figures 6 to 9 The specific structures of the first locking block 100 and the second locking block 200 are described below. In some embodiments, along the extending direction of the first locking block 100, the first fixing part 120 is located between the first connecting structure 110 and the rotating part 130. (Refer to...) Figure 6 In terms of orientation, specifically along the left-right direction, the first fixing part 120 is located between the first connecting structure 110 and the rotating part 130. Along the extending direction of the second locking block 200, the second fixing part 220 is located between the second connecting structure 210 and the rotating groove 230. (Refer to...) Figure 6In terms of orientation, specifically along the left-right direction, the second fixing part 220 is located between the second connecting structure 210 and the rotating groove 230. The first locking block 100 and the second locking block 200 of this solution are arranged as described above. This means that after the first locking block 100 and the second locking block 200 rotate relative to each other until the first fixing part 120 and the second fixing part 220 clamp the headband 20, the first connecting structure 110 engages with the second connecting structure 210, ensuring that the two fixing parts stably clamp the headband 20. This effectively prevents the accessory 10 from detaching from the headphone 1 and improves the stability of the assembly connection between the accessory 10 and the headphone 1.

[0069] Reference Figure 3 , Figure 7 and Figure 8 In some embodiments, the first connecting structure 110 is provided with a first protrusion 140, which extends in a direction away from the first fixing portion 120. (Refer to...) Figure 7 In terms of orientation, the first protrusion 140 can extend laterally away from the first fixing part 120, or it can extend obliquely away from the first fixing part 120. In other embodiments, the first connecting structure 110 is provided with a second protrusion, which extends away from the second fixing part 220. It should be noted that the second protrusion can extend laterally away from the second fixing part 220, or it can extend obliquely away from the second fixing part 220.

[0070] This solution facilitates the operation of the accessory 10 through the first protrusion 140 or the second protrusion, so that the first locking block 100 and the second locking block 200 can rotate relative to each other, and can also improve the structural strength of the first connecting structure 110 and the second connecting structure 210, preventing the accessory 10 from deforming during use.

[0071] The following describes the specific assembly and disassembly process of accessory 10 and headphones 1 according to an embodiment of this application. (Refer to...) Figures 1 to 5 By driving the first protrusion 140 or the second protrusion to rotate the first locking block 100 and the second locking block 200 clockwise relative to each other, the first fixing part 120 and the second fixing part 220 are brought closer together to clamp the headband 20, and the first connecting structure 110 and the second connecting structure 220 are engaged with each other, thus realizing the assembly and connection of the accessory 10 and the headphone 1. By separating the first connecting structure 110 and the second connecting structure 210 by the first protrusion 140 or the second protrusion, and driving the first locking block 100 and the second locking block 200 to rotate counterclockwise relative to each other, the first fixing part 120 and the second fixing part 220 are moved away from each other to release the headband 20, thus realizing the disassembly and detachment of the accessory 10 and the headphone 1.

[0072] Reference Figure 11The second aspect of this utility model provides a headset 1, which includes the accessory 10 described in the above embodiment. In this solution, the second fixing part 220 can be positioned close to the first fixing part 120 and clamped at a specific position on the headband 20. That is, the accessory 10 enables the positioning of the sliding arm, meaning that the user does not need to repeatedly adjust the sliding arm and thus the tightness of the earcups when putting on the headset 1 again. Therefore, this solution allows the headset 1 to adapt to the user's wearing habits, improving the user experience.

[0073] Furthermore, the first connecting structure 110 of the first locking block 100 can engage with the second connecting structure 210 of the second locking block 200, thereby enabling the first fixing part 120 and the second fixing part 220 to stably clamp the headband 20, improving the stability of the assembly connection between the accessory 10 and the headphone 1. Moreover, by rotating the second locking block 200 relative to the first locking block 100, the clamping of the headband 20 by the first fixing part 120 and the second fixing part 220 and the engagement of the second connecting structure 210 with the first connecting structure 110 can be achieved, making the assembly connection operation between the accessory 10 and the headphone 1 convenient and quick. In addition, accessories 300 can be provided on the accessory 10, which facilitates user identification and effectively enhances the overall aesthetics of the headphone 1.
