[0032] The present application provides a headband mechanism, which includes a headband frame, a first adjustment connecting member, a second adjustment connecting member and an adjustment band. The headband frame includes a headband assembly and a positioning assembly. The number of the positioning assemblies is two, and the two positioning assemblies are oppositely connected to the headband assembly. The first adjustment connecting member is connected to the headband assembly. The second adjustment connecting member is adjustably connected to the first adjustment connecting member.

[0033] For the above headband mechanism, two ends of the adjustment band respectively wind around the two positioning assemblies and are connected to the headband assembly. At least one end of the adjustment band is connected to the second adjustment connecting member. Since the first adjustment connecting member is connected to the headband assembly and the second adjustment connecting member is adjustably connected to the first adjustment connecting member, at least one end of the adjustment band can be adjustably connected to the first adjustment connecting member through the second adjustment connecting member, that is, the position of at least one end of the adjustment band on the first adjustment connecting member is adjustable. Further, the adjustment range of the length of the adjustment band between the two positioning assemblies is larger, and further the adjustment range of the position of the earphone connected to the headband assembly is larger, that is, the adjustment range of the wearing position of the headphone is larger. Moreover, since there is no need to increase the telescopic structure to increase the adjustment range of the wearing position, the complexity of the headband mechanism is reduced, and at the same time, the structure of the headband mechanism is compact.

[0034] To better understand the technical solution and beneficial effects of the present application, the following further describes the present application in detail with specific embodiments:

[0035] As Figures 1 to 3As shown, the headband mechanism 10 of an embodiment includes a headband frame 100, a first adjustment connecting member 200, a second adjustment connecting member 400, and an adjustment band 300. The headband frame 100 includes a headband assembly 110 and a positioning assembly 120. The number of the positioning assemblies 120 is two, and the two positioning assemblies 120 are oppositely connected to the headband assembly 110. The first adjustment connecting member 200 is connected to the headband assembly 110. The second adjustment connecting member 400 is adjustably connected to the first adjustment connecting member 200. The adjustment band 300 is located inside the headband assembly 110. Two ends of the adjustment band 300 are respectively wound around the positioning assemblies 120 and connected to the headband assembly 110, wherein at least one end of the adjustment band 300 is connected to the second adjustment connecting member 400, so that at least one end of the adjustment band 300 is adjustably connected to the first adjustment connecting member 200, and further the length of the adjustment band 300 between the two positioning assemblies 120 is adjustable.

[0036] In this embodiment, the headband frame 100 includes a headband assembly 110 and a positioning assembly 120. The headband assembly 110 functions to support various components. The number of the positioning assemblies 120 is two, and the two positioning assemblies 120 are oppositely connected to the headband assembly 110. The first adjustment connecting member 200 is connected to the headband assembly 110. The adjustment band 300 is disposed on the headband assembly 110. The adjustment band 300 is used to be worn on the head of a user, that is, the adjustment band 300 is hung on the head of the user. Two ends of the adjustment band 300 are respectively wound around the two positioning assemblies 120 and connected to the headband assembly 110. At least one end of the adjustment band 300 is connected to the second adjustment connecting member 400. The second adjustment connecting member 400 is adjustably connected to the first adjustment connecting member 200, so that at least one end of the adjustment band 300 is adjustably connected to the first adjustment connecting member 200 through the second adjustment connecting member 400, and the length of the adjustment band 300 between the two positioning assemblies 120 is adjustable. That is, by adjusting the position of the second adjustment connecting member 400 on the first adjustment connecting member 200, the length of the adjustment band 300 between the two positioning assemblies 120 can be controlled, so as to adjust the position of the earphone connected to the headband assembly 110 to be suitable for the user.

[0037] It should be noted that the length of the adjustment band 300 between the two positioning assemblies 120 refers to the length of the adjustment band 300 in the normal state, that is, the length of the adjustment band 300 when it is not stretched.

[0038] For the above-mentioned headband mechanism 10, both ends of the adjustment band 300 are respectively wound around two positioning components 120 and connected to the headband component 110. At least one end of the adjustment band 300 is connected to the second adjustment connecting piece 400. Since the first adjustment connecting piece 200 is connected to the headband component 110 and the second adjustment connecting piece 400 is adjustably connected to the first adjustment connecting piece 200, at least one end of the adjustment band 300 can be adjustably connected to the first adjustment connecting piece 200 through the second adjustment connecting piece 400, that is, the position of at least one end of the adjustment band 300 on the first adjustment connecting piece 200 is adjustable. Furthermore, the adjustment range of the length of the adjustment band 300 between the two positioning components 120 is relatively large. As a result, the adjustment range of the position of the ear cups connected to the headband component 110 is relatively large, that is, the adjustment range of the wearing position of the head-mounted headphones is relatively large. Moreover, since there is no need to add a telescopic structure to increase the adjustment range of the wearing position, the complexity of the headband mechanism 10 is reduced, and at the same time, the structure of the headband mechanism 10 is compact.

[0039] As Figure 2 and Figure 3 shown, in one embodiment, the number of the second adjustment connecting pieces 400 is two. Both of the two second adjustment connecting pieces 400 are adjustably connected to the first adjustment connecting piece 200. Both ends of the adjustment band 300 are respectively connected to the two second adjustment connecting pieces 400, so that both ends of the adjustment band 300 are adjustably connected to the headband component 110. In this embodiment, since both ends of the adjustment band 300 are connected to the second adjustment connecting piece 400, both ends of the adjustment band 300 can be adjustably connected to the first adjustment connecting piece 200, that is, the positions of both ends of the adjustment band 300 on the first adjustment connecting piece 200 are adjustable. Furthermore, the adjustment range of the length of the adjustment band 300 between the two positioning components 120 is even larger. As a result, the adjustment range of the position of the ear cups connected to the headband component 110 is even larger, that is, the adjustment range of the wearing position of the head-mounted headphones is even larger.

[0040] As Figure 2 and Figure 3 shown, in one embodiment, the adjustment band 300 is an elastic structure. In this embodiment, by stretching the adjustment band 300, the length of the adjustment band 300 between the two positioning components 120 can also be controlled, so that the adjustment range of the length of the adjustment band 300 between the two positioning components 120 is even larger. As a result, the adjustment range of the wearing position of the head-mounted headphones is even larger, and the adaptability of the head-mounted headphones is further improved.

[0041] As Figure 2 and Figure 3As shown, in one embodiment, the first adjusting connection member 200 is one of a hook-and-loop fastener's loop side structure and a hook-and-loop fastener's hook side structure, and the second adjusting connection member 400 is the other of the hook-and-loop fastener's loop side structure and the hook-and-loop fastener's hook side structure. In this embodiment, the first adjusting connection member 200 is a hook-and-loop fastener's loop side structure, and the second adjusting connection member 400 is a hook-and-loop fastener's hook side structure; or the first adjusting connection member 200 is a hook-and-loop fastener's hook side structure, and the second adjusting connection member 400 is a hook-and-loop fastener's loop side structure. In this way, both ends of the adjusting belt 300 are adjustably connected to the headband assembly 110 through the hook-and-loop fastener, improving the convenience of adjusting the adjusting belt 300, and further improving the efficiency of adjusting the adjusting belt 300.

[0042] As Figure 3 shown, further, the first adjusting connection member 200 is adhered to the headband holder 100 to improve the convenience of installing the first adjusting connection member 200 and at the same time improve the convenience of disassembling the first adjusting connection member 200.

[0043] As Figure 3 shown, further, the second adjusting connection member 400 is sewn to the adjusting belt 300 to improve the connection strength between the second adjusting connection member 400 and the adjusting belt 300, and further inhibit the problem of the adjusting belt 300 separating from the headband assembly 110.

[0044] In another embodiment, the first adjusting connection member 200 is provided with a plurality of first card slots arranged along the extending direction of the headband assembly 110, the second adjusting connection member 400 is a first snap structure, and the second adjusting connection member 400 is snapped into one of the first card slots. By adjusting the second adjusting connection member 400 to be snapped into different first card slots, the length of the adjusting belt 300 between the two positioning components 120 is controlled, and further the adjustment range of the length of the adjusting belt 300 between the two positioning components 120 is relatively large, and further the adjustment range of the wearing position of the headset is improved.

[0045] Of course, in yet another embodiment, the first adjusting member is a second snap structure, the second adjusting member is provided with a plurality of second card slots arranged along the length direction of the adjusting belt 300, and by adjusting the first adjusting member to be snapped into different second card slots, the length of the adjusting belt 300 between the two positioning components 120 is controlled, and further the adjustment range of the length of the adjusting belt 300 between the two positioning components 120 is relatively large, and further the adjustment range of the wearing position of the headset is improved.

[0046] As Figures 1 to 3As shown, in one embodiment, the headband assembly 110 is provided with two winding holes 111, and each of the positioning assemblies 120 is correspondingly disposed in the winding holes 111 and connected to the headband assembly 110. In this embodiment, two winding holes 111 are respectively formed at both ends of the headband assembly 110, and the two winding holes 111 are arranged in one-to-one correspondence with the two positioning assemblies 120. Each positioning assembly 120 is located in the corresponding winding hole 111 and connected to the headband assembly 110, making the structure of the headband frame 100 relatively compact.

[0047] As Figure 3 shown, in one embodiment, the first adjustment connecting member 200 is connected to the inner side of the headband assembly 110. In this embodiment, the first adjustment connecting member 200 is connected to the inner side of the headband assembly 110, avoiding the exposure of the first adjustment connecting member 200 to the outside, thereby avoiding the problem that the first adjustment connecting member 200 is scratched by the outside and falls off, and further improving the position stability of the first adjustment connecting member 200. The adjustment belt 300 is connected to the headband assembly 110 through the first adjustment connecting member 200 and the second adjustment connecting member 400, thus improving the position stability of the adjustment belt 300.

[0048] As Figure 2 and Figure 3 shown, in one embodiment, the first adjustment connecting member 200 is arranged along the extending direction of the headband frame 100, so that the moving range of the first adjustment connecting member 200 is larger, and further improving the length adjustment range of the adjustment belt 300 between the two positioning assemblies 120.

[0049] As Figures 1 to 3 shown, in one embodiment, the number of the first adjustment connecting members 200 is two, and the two first adjustment connecting members 200 are respectively connected to the headband frame 100. In this embodiment, the number of the first adjustment connecting members 200 is two, so that the pulling force of the adjustment belt 300 on the first adjustment connecting member 200 is distributed to the two first adjustment connecting members 200, thus suppressing the problem that the first adjustment connecting member 200 detaches from the headband assembly 110, and further improving the position stability of the adjustment belt 300.

[0050] It can be understood that due to the limited length of the first adjusting connecting member 200, the connection position of the second adjusting connecting member 400 is limited, and further the adjustment range of the length of the adjusting belt 300 between the two positioning components 120 is limited. Moreover, the positions of the first adjusting connecting member 200 and the second adjusting connecting member 400 are on the inner side of the headband assembly 110. When the user wears the headphone, the user needs to take off the headphone to adjust the position of the second adjusting connecting member 400, and then wear it on the head to feel whether the wearing position is adjusted to a comfortable position. If the wearing position is still not appropriate, the user still needs to take off the headphone to adjust the position of the second adjusting connecting member 400. In this way, the adjustment of the wearing position is relatively cumbersome, and further the adjustment efficiency of the wearing position is low, that is, the adjustment efficiency of the length of the adjusting belt 300 between the two positioning components 120 is low.

[0051] Therefore, as Figure 4 and Figure 5 shown, in one embodiment, the headband assembly 110 is provided with two sliding grooves 112 along the extending direction, and the two sliding grooves 112 are respectively corresponding and communicated with the two winding holes 111. Each positioning component 120 includes a sliding member 121, a rotating member 122 and a driving gear 123. The sliding member 121 of each positioning component 120 is located in the corresponding winding hole 111, and the sliding member 121 of each positioning component 120 is also slidably disposed in the corresponding sliding groove 112. The sliding member 121 of each positioning component 120 is provided with a meshing rack 1211 along the extending direction of the headband assembly 110. One end of the adjusting belt 300 is wound around the sliding member 121 of the corresponding positioning component 120, and the adjusting belt 300 contacts the side of the sliding member 121 of each positioning component 120 away from the meshing rack 1211. The rotating member 122 of each positioning component 120 is rotatably connected to the headband assembly 110, and the rotating member 122 of each positioning component 120 protrudes from the headband assembly 110. The driving gear 123 of each positioning component 120 is fixedly sleeved on the corresponding rotating member 122, and the driving gear 123 of each positioning component 120 is meshed and connected with the meshing rack 1211 of the corresponding sliding member 121.

[0052] In this embodiment, when the user wears the head-mounted earphone, the headband mechanism 10 is hung on the user's head. The rotating member 122 of each positioning component 120 is rotated outside the headband mechanism 10 to rotate the corresponding driving gear 123, so that the corresponding driving gear 123 meshes and drives with the meshing rack 1211 of the corresponding sliding member 121, and then the corresponding sliding member 121 slides in the corresponding sliding groove 112, that is, the corresponding sliding member 121 slides along the extension direction of the headband assembly 110, and then the two winding points of the adjusting band 300 move along the extension direction of the headband assembly 110. Specifically, when the corresponding sliding member 121 moves upward along the headband assembly 110, the adjusting band 300 at the upper end of the corresponding sliding member 121 becomes slack. At this time, the adjusting band 300 between the two positioning components 120 is pulled to tighten the adjusting band 300 at the upper end of the corresponding sliding member 121, and at the same time, the length of the adjusting band 300 between the sliding members 121 of the two positioning components 120 is increased. When the corresponding sliding member 121 moves downward along the headband assembly 110, the corresponding sliding member 121 pulls the adjusting band 300 between the two positioning components 120 into the headband assembly 110, so that the length of the adjusting band 300 between the two positioning components 120 is shortened.

[0053] In this way, adjusting the positions of each second adjusting connecting member 400 and each sliding member 121 can adjust the length of the adjusting band 300 between the two positioning components 120, improving the adjustment range of the adjusting band 300, and further improving the adjustment range of the matching position of the headband mechanism. In addition, rotating the rotating member 122 can control the length of the adjusting band 300 between the two positioning components 120, enabling the adjustment of the adjusting band 300 without removing the headband mechanism 10, thereby improving the convenience of controlling the adjusting band 300 and further improving the efficiency of controlling the adjusting band 300.

[0054] As Figure 5 shown, further, each positioning component 120 further includes an isolating member 124. The isolating member 124 of each positioning component 120 is rotatably connected to the headband assembly 110. The isolating member 124 of each positioning component 120 is spaced from the corresponding driving gear 123. The adjusting band 300 is also wound around the isolating member 124 of each positioning component 120 to prevent the adjusting band 300 from contacting the driving gear 123 of each positioning component 120, thereby preventing the driving gear 123 of each positioning component 120 from hindering the movement of the adjusting band 300.

[0055] As Figure 6As shown, further, the rotating member 122 of each positioning component 120 includes a connecting portion 1221, a telescopic portion 1222, and a rotating portion 1223. The connecting portion 1221 of the rotating member 122 of each positioning component 120 is fixedly sleeved with the corresponding driving gear 123. The connecting portion 1221 of the rotating member 122 of each positioning component 120 is provided with a communicating telescopic hole 1221a and a limiting chute 1221b along its extending direction. The telescopic portion 1222 of the rotating member 122 of each positioning component 120 protrudes with a limiting body 1222a. The telescopic portion 1222 of the rotating member 122 of each positioning component 120 telescopically moves within the corresponding telescopic hole 1221a. The telescopic portion 1222 of the rotating member 122 of each positioning component 120 and the corresponding connecting portion 1221 are in interference fit to prevent the telescopic portion 1222 of the rotating member 122 of each positioning component 120 from telescopically moving within the corresponding telescopic hole 1221a during non-artificial operation. And the limiting body 1222a of the telescopic portion 1222 of the rotating member 122 of each positioning component 120 slides within the corresponding limiting chute 1221b to prevent the telescopic portion 1222 of the rotating member 122 of each positioning component 120 from rotating relative to the corresponding connecting portion 1221, so that the telescopic portion 1222, the corresponding connecting portion 1221, and the corresponding driving gear 123 of the rotating member 122 of each positioning component 120 rotate synchronously.

[0056] As Figure 7 shown, further, the telescopic portion 1222 of the rotating member 122 of each positioning component 120 is also rotatably connected to the headband assembly 110. The rotating portion 1223 of the rotating member 122 of each positioning component 120 is connected to the corresponding telescopic portion 1222, and the rotating portion 1223 of the rotating member 122 of each positioning component 120 is located outside the headband assembly 110, so that the rotating member 122 of each positioning component 120 extends out of the headband assembly 110. The rotating portion 1223 of the rotating member 122 of each positioning component 120 is provided with a stop groove. Two stop portions protrude from the outside of the headband assembly 110. The two stop portions are provided in one-to-one correspondence with the two positioning components 120. Each stop portion is used to be snapped into the corresponding stop groove when the corresponding rotating portion 1223 abuts against the headband assembly 110 to prevent the corresponding rotating portion 1223 from rotating.

[0057] In this embodiment, when it is necessary to move the sliding member 121 of each positioning component 120, the rotating portion 1223 of the rotating member 122 of each positioning component 120 is pulled, so that a part of the corresponding telescopic portion 1222 extends out of the corresponding connecting portion 1221, and at the same time, the corresponding rotating portion 1223 is separated from the headband assembly 110, so that each stop portion of the headband assembly 110 is separated from the corresponding stop groove. At this time, by rotating the corresponding rotating portion 1223, the corresponding sliding member 121 can be moved. When it is not necessary to move the sliding member 121 of each positioning component 120, the rotating portion 1223 of the rotating member 122 of each positioning component 120 is pressed, so that a part of the corresponding telescopic portion 1222 retracts into the corresponding connecting portion 1221, and at the same time, the corresponding rotating portion 1223 abuts against the headband assembly 110, so that each stop portion of the headband assembly 110 is clamped in the stop groove of the corresponding rotating portion 1223, so that the stop portion of the headband assembly 110 restricts the rotation of the corresponding rotating portion 1223, thus avoiding the movement of the corresponding sliding member 121. In this way, the movement of the sliding member 121 under non-human operation is avoided, thereby improving the position stability of the sliding member 121, and further improving the length stability of the adjustment belt 300 between the two positioning components 120. It can be understood that both ends of the adjustment belt 300 are respectively wound around the two sliding members 121, so that there is a frictional force between the adjustment belt 300 and each sliding member 121. When each sliding member 121 moves upward along the headband assembly 110 respectively, the adjustment belt 300 at the upper end of each sliding member 121 will become loose. At this time, there is a large resistance when pulling the adjustment belt 300 between the two positioning components 120, so that a greater force is required to pull the adjustment belt 300 between the two positioning components 120, and thus the convenience of pulling the adjustment belt 300 between the two positioning components 120 is poor.

[0058] To improve the convenience of pulling the adjustment belt 300 between the two positioning components 120, as Figures 4 to 6As shown, further, each positioning component 120 includes a rotating member 125 and a belt pulling gear 126. The rotating member 125 of each positioning component 120 is rotatably connected to the headband component 110, and the rotating member 125 of each positioning component 120 extends out of the headband component 110. The belt pulling gear 126 of each positioning component 120 is coaxially fixed to the corresponding rotating member 125 and is correspondingly arranged with the corresponding sliding member 121. The adjusting belt 300 is provided with a plurality of clamping grooves, and the plurality of clamping grooves are arranged along the extending direction of the adjusting belt 300. The belt pulling gear 126 of each positioning component 120 meshes with at least one clamping groove. The belt pulling gear 126 of each positioning component 120 is used for meshing and driving with the adjusting belt 300 when rotating, so that the adjusting belt 300 moves along the corresponding sliding member 121. In this embodiment, when the adjusting belt 300 at the upper end of the sliding member 121 of each positioning component 120 is slack, rotate the corresponding rotating member 125 to make the corresponding belt pulling gear 126 rotate, so that the corresponding belt pulling gear 126 meshes and drives with the adjusting belt 300, and then the adjusting belt 300 moves downward along the corresponding sliding member 121, and then the adjusting belt 300 at the upper end of the sliding member 121 of each positioning component 120 is tightened, and at the same time, the length of the adjusting belt 300 between the two positioning components 120 is increased. In this way, the convenience of pulling the adjusting belt 300 between the two positioning components 120 is improved, and further the efficiency of pulling the adjusting belt 300 between the two positioning components 120 is improved.

[0059] However, after driving the corresponding sliding member 121 to move upward through the meshing transmission between the driving gear 123 of each positioning component 120 and the corresponding sliding member 121, it is still necessary to twist the corresponding rotating member 125, that is, two-step operations are required when the sliding member 121 of each positioning component 120 moves upward, so that the moving efficiency of the sliding member 121 of each positioning component 120 is relatively low, and further the adjusting efficiency of the adjusting belt 300 is relatively low. In order to further improve the adjusting efficiency of the adjusting belt 300, as Figure 4 shown, in one embodiment, the rotating member 122 of each positioning component 120 is meshingly connected to the corresponding rotating member 125. In this embodiment, when the rotating member 122 of each positioning component 120 rotates in one direction, the corresponding rotating member 125 rotates in the opposite direction, so that while the sliding member 121 of each positioning component 120 moves upward, the corresponding rotating member 122 drives the corresponding belt pulling gear 126 to rotate, so that the corresponding belt pulling gear 126 tightens the adjusting belt 300 at the upper end of the sliding member 121 of each positioning component 120, and further avoids the situation that the adjusting belt 300 at the upper end of the sliding member 121 of each positioning component 120 is slack. In this way, only by rotating the rotating member 122 can two operations be realized, and the adjusting efficiency of the adjusting belt 300 is improved.

[0060] This application also provides a pair of head-mounted earphones, including the headband mechanism 10 described in any of the above embodiments.

[0061] As Figures 1 to 3 shown, further, the headband mechanism 10 includes a headband frame 100, a first adjustment connecting member 200, a second adjustment connecting member 400, and an adjustment band 300. The headband frame 100 includes a headband assembly 110 and a positioning assembly 120. The number of the positioning assemblies 120 is two, and the two positioning assemblies 120 are oppositely connected to the headband assembly 110. The first adjustment connecting member 200 is connected to the headband assembly 110. The second adjustment connecting member 400 is adjustably connected to the first adjustment connecting member 200. The adjustment band 300 is located inside the headband assembly 110. Both ends of the adjustment band 300 are respectively wound around the positioning assemblies 120 and connected to the headband assembly 110, wherein at least one end of the adjustment band 300 is connected to the second adjustment connecting member 400, so that at least one end of the adjustment band 300 is adjustably connected to the first adjustment connecting member 200, and further the length of the adjustment band 300 located between the two positioning assemblies 120 is adjustable.

[0062] In this embodiment, the headband frame 100 includes a headband assembly 110 and a positioning assembly 120. The headband assembly 110 functions to support various components. The number of the positioning assemblies 120 is two, and the two positioning assemblies 120 are oppositely connected to the headband assembly 110. The first adjustment connecting member 200 is connected to the headband assembly 110. The adjustment band 300 is disposed on the headband assembly 110. The adjustment band 300 is used for wearing on the head of a user, that is, the adjustment band 300 is hung on the head of the user. Both ends of the adjustment band 300 are respectively wound around the two positioning assemblies 120 and connected to the headband assembly 110. At least one end of the adjustment band 300 is connected to the second adjustment connecting member 400.

That is, by adjusting the position of the second adjustment connecting member 400 on the first adjustment connecting member 200, the length of the adjustment band 300 between the two positioning assemblies 120 can be controlled, so as to adjust the position of the earphone connected to the headband assembly 110 to be suitable for the user.

[0063] It should be noted that the length of the adjustment band 300 between the two positioning assemblies 120 refers to the length of the adjustment band 300 in the normal state, that is, the length of the adjustment band 300 when it is not stretched.

[0064] For the above-mentioned headphone, both ends of the adjusting strap 300 are respectively wound around two positioning components 120 and connected to the headband assembly 110.
