The adjusting assembly 10 of the present application will be introduced below with reference to Figures 1 to 10 Specifically, the adjusting assembly 10 comprises a support arm 100 and a sliding arm 200.

[0055] With reference to Figures 1 to 7The support arm 100 is used to connect the ear hook 30. Specifically, the ear hook 30 can be connected to an end of the support arm 100 which is away from the headband 20. For the purpose of describing and understanding the specific structure of the support arm 100, a first direction X is defined. Referring to Figure 7 In the orientation, the first direction X can point to the front-back direction. The support arm 100 can be arranged to extend along the first direction X, and the specific extension length thereof can be determined according to actual conditions. The support arm 100 can be provided with a connecting hole 110 for the sliding arm 200 to pass through. It can be understood that the connecting hole 110 can also be arranged to extend along the first direction X. The inner hole wall 111 of the connecting hole 110 is provided with a first clamping groove 120 for clamping the sliding arm 200, and the first clamping groove 120 is arranged to extend along the first direction X.

[0056] Referring to Figures 4 to 8 The sliding arm 200 is used to connect the headband 20. It can be understood that the sliding arm 200 can be arranged to be integrally connected with the headband 20, or arranged to be separately connected. The sliding arm 200 can slide relative to the support arm 100, that is, the tightness adjustment of the headset 1 can be realized. Specifically, the sliding arm 200 can pass through the connecting hole 110, and the specific passing depth of the sliding arm 200 can be determined according to actual conditions.

[0057] Referring to Figure 5 , Figures 7 to 10 The specific fixing arrangement of the sliding arm 200 and the support arm 100 will be introduced below. The sliding arm 200 can be provided with a first clamping block 210 which can be arranged to fit the first clamping groove 120. The first clamping block 210 passes through the first clamping groove 120, and during the sliding process of the sliding arm 200 in the connecting hole 110 along the first direction X, the first clamping block 210 is always in interference fit with the first clamping groove 120, that is, under the condition of not applying a large external force, the sliding arm 200 can be stably kept at a target position relative to the support arm 100 for the user to wear comfortably. When the sliding arm 200 is driven to slide relative to the support arm 100, the tightness adjustment operation can be realized.

[0058] The utility model discloses a technical scheme, adjusting assembly 10 is used for head -wearing earphone 1. Adjusting assembly 10 includes support arm 100 and sliding arm 200. Support arm 100 is suitable for connecting ear hook 30. Support arm 100 is arranged along the first direction X and is equipped with connecting hole 110 in it, and the inner hole wall 111 of connecting hole 110 is equipped with the first clamping groove 120 arranged along the first direction X. Sliding arm 200 is slidably connected with support arm 100, and sliding arm 200 is arranged in connecting hole 110, and sliding arm 200 is suitable for connecting headband 20. Among them, sliding arm 200 is equipped with the first clamping block 210, and the first clamping block 210 is arranged in the first clamping groove 120. In the prior art, a plurality of clamping grooves are arranged in the support arm along the extension direction of the support arm, and the protrusions of the sliding arm are switched in the clamping grooves to realize the tightness adjustment of the head -wearing earphone. In order to improve the structural strength of the clamping groove and guarantee the fixing effect of the clamping groove on the protrusion, the adjacent two clamping grooves need to be spaced apart by a certain distance, so that a large number of clamping grooves cannot be arranged in the support arm, that is, the adjustable range of the sliding assembly is small, resulting in fewer tightness adjustment gears of the head -wearing earphone and narrower application range. In the present application, the first clamping block 210 is always in interference fit with the first clamping groove 120 during the sliding process of the sliding arm 200 in the connecting hole 110, that is, the sliding arm 200 can be stably kept at any position relative to the support arm 100. Therefore, the present application can effectively expand the adjustable range of the adjusting assembly 10, greatly increase the tightness adjustment gears of the head -wearing earphone 1, and expand the application range of the head -wearing earphone 1. Moreover, the first clamping groove 120 of the present application is arranged along the first direction X, that is, the structure of the first clamping groove 120 is continuous, that is, the machining difficulty of the support arm 100 can be reduced, and the processing cost can be reduced.

[0059] Referring to Figure 5 , Figures 8 to 10 , the specific structure of the sliding arm 200 will be introduced below. In some embodiments, the sliding arm 200 includes a second clamping block 220, which is arranged opposite to the first clamping block 210. The structure of the second clamping block 220 can be the same as or different from that of the first clamping block 210. The present application takes the structure of the first clamping block 210 and the second clamping block 220 as an example for illustration. Referring to Figure 7 , the first clamping block 210 can be arranged opposite to the second clamping block 220 along the up-down direction.

[0060] The specific structure of the support arm 100 will be introduced below. In some embodiments, the inner hole wall 111 of the connecting hole 110 in the support arm 100 is provided with a second clamping groove 130, which can be arranged along the first direction X. The second clamping groove 130 can be adapted to the arrangement of the second clamping block 220, that is, the structure of the second clamping groove 130 can be the same as that of the first clamping groove 120. Referring to Figure 7 , the first clamping groove 120 and the second clamping groove 130 can be arranged opposite to each other along the up-down direction.

[0061] The second clamping block 220 can be inserted into the second clamping slot 130, and during the sliding of the sliding arm 200 along the first direction X in the connecting hole 110, the second clamping block 220 is always in interference fit with the second clamping slot 130, that is, without the application of a large external force, the sliding arm 200 can be stably kept at a target position relative to the support arm 100 for comfortable wearing by the user. When the sliding arm 200 is driven to slide relative to the support arm 100, the tightness adjustment operation can be realized. The second clamping block 220 inserted into the second clamping slot 130 in the present scheme can effectively enhance the damping effect between the sliding arm 200 and the support arm 100, so that the sliding arm 200 can be stably kept at the target position, preventing the tightness of the headphones 1 from being greatly and unexpectedly fluctuated.

[0062] It should be noted that in some embodiments, the sliding arm 200 can be provided with a third clamping block, and the support arm 100 can be provided with a third clamping slot, and the third clamping block can be inserted into the third clamping slot, that is, the damping effect between the sliding arm 200 and the support arm 100 can be further enhanced. In other embodiments, the sliding arm 200 can be provided with the second clamping slot 130, and the support arm 100 can be provided with the second clamping block 220, and the second clamping block 220 can be inserted into the second clamping slot 130. The specific structure of the sliding arm 200 can be determined according to actual conditions.

[0063] Referring to Figures 4 to 7 In some embodiments, in order to facilitate the description and understanding of the specific structure of the support arm 100, a second direction Y is defined. The second direction Y is perpendicular to the first direction X, and the first direction X is along the front-back direction, and the second direction Y is along the up-down direction. Figure 7 The support arm 100 includes a first arm body 140 and a second arm body 150 arranged relative to each other along the second direction Y. The first arm body 140 can jointly enclose the connecting hole 110 with the second arm body 150 to connect the sliding arm 200. The first arm body 140 and the second arm body 150 are detachably connected, that is, the first arm body 140 can be arranged separately from the second arm body 150, that is, the connection of the sliding arm 200 can be facilitated.

[0064] It should be noted that the structure of the second arm body 150 can be the same as or different from that of the first arm body 140, and the present application embodiment is described by taking the structure of the first arm body 140 and the second arm body 150 as an example. Among them, the first clamping slot 120 can be arranged on the first arm body 140, and the second clamping slot 130 can be arranged on the second arm body 150. Along the second direction Y, referring to Figure 7In the orientation, i.e. in the up-down direction, the first arm body 140 can be relatively close to the second arm body 150 to jointly hold the sliding arm 200. It can be understood that the first arm body 140 and the second arm body 150 can hold the first clamping block 210 of the sliding arm 200 to enhance the damping effect between the support arm 100 and the sliding arm 200, so that the sliding arm 200 can be stably kept at the target position, preventing the headset 1 from having a large accidental fluctuation in tightness.

[0065] With reference to Figure 4 , Figure 5 and Figure 9 , the specific connection structure of the first arm body 140 and the second arm body 150 will be introduced below. In some embodiments, the adjustment assembly 10 includes a fastener 300. It can be understood that the fastener 300 can be a bolt or a screw. The first arm body 140 can be provided with a first hole body 141, and the second arm body 150 can be provided with a second hole body 151. In the second direction Y, with reference to Figure 9 In the orientation, i.e. in the up-down direction, the fastener 300 can be at least partially threaded through the first hole body 141 and the second hole body 151 to force the first arm body 140 and the second arm body 150 to be relatively close to each other, thereby achieving stable holding of the sliding arm 200. Further, the fastener 300 can be threaded through the first arm body 140 and screwed with the second arm body 150, so that the first arm body 140 is close to the second arm body 150.

[0066] It should be noted that in other embodiments, the fastener 300 can be a rivet, which can be threaded through the first hole body 141 of the first arm body 140 and the second hole body 151 of the second arm body 150, and the rivet is riveted to make the first arm body 140 and the second arm body 150 close to each other. The embodiments of the present application take the screw as an example for illustration.

[0067] With reference to Figure 4 , Figure 8 and Figure 10 , in some embodiments, the adjustment assembly 10 includes a cap body 400. The cap body 400 can be a screw cap. The first arm body 140 and the second arm body 150 can be jointly screwed into the cap body 400. Further, the sliding arm 200 can be threaded through the cap body 400 to be threaded into the connecting hole 110. The first arm body 140 and the second arm body 150 of the present scheme are screwed into the cap body 400, which can effectively improve the stability of the assembly connection of the first arm body 140 and the second arm body 150, and enhance the damping effect between the support arm 100 and the connecting arm.

[0068] With reference to Figures 1 to 4In some embodiments, the adjusting assembly 10 comprises a shell 500, which can surround and wrap the first arm body 140 and the second arm body 150 along the circumference of the support arm 100. It can be understood that the shell 500 can be a stainless steel tube. The shell 500 of the present solution wraps the first arm body 140 and the second arm body 150, which can further improve the stability of the assembly connection of the first arm body 140 and the second arm body 150, and guarantee the damping effect between the support arm 100 and the connecting arm.

[0069] Referring to Figures 4 to 10 In some embodiments, the adjusting assembly 10 comprises a damping sleeve 600. The damping sleeve 600 can be arranged in the cap body 400. Specifically, the damping sleeve 600 can surround the sliding arm 200, i.e., the inner ring of the damping sleeve 600 can be connected to the sliding arm 200, and the outer ring of the damping sleeve 600 can be connected to the cap body 400. Therefore, the damping sleeve 600 can inhibit the sliding of the sliding arm 200 relative to the support arm 100. The damping sleeve 600 of the present solution can further improve the damping effect between the support arm 100 and the sliding arm 200, so that the sliding arm 200 can be stably maintained at the target position, preventing the tightness of the headphones 1 from being greatly and unexpectedly fluctuated.

[0070] Referring to Figure 4 , Figure 5 With Figure 9 , the specific rotational adjustment of the ear hook 30 relative to the adjusting assembly 10 will be introduced below. In some embodiments, the adjusting assembly 10 comprises a rotating shaft 700 and a damping block 800. The rotating shaft 700 is used to connect the ear hook 30, and the rotating shaft 700 is rotationally connected to the support arm 100, i.e., the ear hook 30 can be rotated relative to the support arm 100 through the rotating shaft 700 to adjust the wearing angle and the like. The two sides of the rotating shaft 700 can be connected to the rotating shaft 700 and the support arm 100, respectively, i.e., the damping effect of the rotating shaft 700 and the support arm 100 can be enhanced, effectively inhibiting the rotation of the rotating shaft 700 relative to the support arm 100. That is, under the condition of not applying a large external force, the rotating shaft 700 can be stably maintained at the target position for comfortable wearing by the user. When the ear hook 30 is driven to rotate relative to the support arm 100, the rotational adjustment operation of the ear hook 30 can be realized, which is suitable for various wearing needs.

[0071] Referring to Figure 4 , Figure 5 With Figure 9 In some embodiments, the support arm 100 is provided with a mounting hole 160, and the rotating shaft 700 can at least partially pass through the mounting hole 160, i.e., the stability of the assembly connection of the rotating shaft 700 and the support arm 100 can be guaranteed. The damping block 800 can be arranged in the mounting hole 160. Specifically, the damping block 800 can surround the rotating shaft 700, i.e., the rotating shaft 700 can pass through the damping block 800. Referring to Figure 9, the rotating shaft 700 can be provided with a limiting block 710, and the mounting hole 160 can be provided with a limiting groove 170. The limiting block 710 can cooperate with the limiting groove 170, that is, the rotating range of the rotating shaft 700 relative to the support arm 100 can be limited. The damping block 800 of the scheme can be arranged around the rotating shaft 700, that is, the damping effect can be effectively improved. The limiting block 710 cooperates with the limiting groove 170 to limit the rotating range of the rotating shaft 700, preventing excessive invalid rotation of the rotating shaft 700 and interfering with normal wearing of the user and aggravating the wear of the rotating shaft 700.

[0072] Referring to Figure 8 and Figure 9 , the specific assembly of the support arm 100 and the rotating shaft 700 will be introduced below. In some embodiments, the end of the support arm 100 towards the ear hook 30 can be provided with a first stop portion 180. The first stop portion 180 is used to abut the rotating shaft 700 to prevent the rotating shaft 700 from coming out of the mounting hole 160 of the support arm 100. The scheme can improve the reliability of the rotating connection of the rotating shaft 700 and the support arm 100, and realize continuous and stable adjustment of the ear hook 30.

[0073] Referring to Figure 8 and Figure 10 , the specific assembly of the support arm 100 and the sliding arm 200 will be introduced below. In some embodiments, the end of the support arm 100 away from the ear hook 30 can be provided with a second stop portion 190, and the second stop portion 190 is used to abut the limiting block 710 to prevent the sliding arm 200 from coming out of the connecting hole 110 of the support arm 100. The scheme can improve the reliability of the assembly connection of the support arm 100 and the sliding arm 200, so that the headset 1 can continuously and stably perform the tightness adjustment operation.

[0074] Referring to Figures 1 to 4 , the second aspect embodiment of the present application proposes a headset 1, which comprises the adjustment assembly 10, the headband 20 and the ear hook 30 of the above-mentioned embodiments. The headband 20 can be connected to one end of the adjustment assembly 10, and the ear hook 30 can be connected to the end of the adjustment assembly 10 away from the headband 20. Referring to Figure 1 , the headband 20 can be connected to the upper end of the adjustment assembly 10, and the ear hook 30 can be connected to the lower end of the adjustment assembly 10. Further, the headband 20 can be in a silk shape, and the specific structure and size of the headband 20 can be determined according to actual conditions. The headset 1 of the scheme can effectively expand the adjustable range of the adjustment assembly 10, greatly increase the tightness adjustment range of the headset 1, and expand the application range of the headset 1.
