[0038] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the headphones of this application.

[0040] In one embodiment, the headphones include a headband assembly 10 and earcups 20. The headband assembly 10 is connected to the earcups 20. The headband assembly 10 surrounds and forms a wearing area 11. When a user wears the headphones, the user's head is located in the wearing area 11, while the earcups 20 are located at the user's ears. Audio information transmitted by the headphones is output to the user through the earcups 20.

[0041] Furthermore, the headband support device 10 includes a headband fixing bracket 12 and a sliding arm 13. The headband fixing bracket 12 surrounds and forms the aforementioned wearing area 11. The sliding arm 13 is slidably disposed on the headband fixing bracket 12, and the sliding arm 13 is also connected to the earcup device 20. The sliding arm 13 slides relative to the headband fixing bracket 12, such that the sliding arm 13 extends or retracts relative to the headband fixing bracket 12 to adjust the position of the earcup device 20, so that the earcup device 20 is located at the user's ears after the user wears the headphones.

[0042] This embodiment uses the extension amount to describe the degree to which the sliding arm 13 extends relative to the head-mounted support 12. It can be understood that when the sliding arm 13 extends relative to the head-mounted support 12, the extension amount of the sliding arm 13 increases; while when the sliding arm 13 retracts relative to the head-mounted support 12, the extension amount of the sliding arm 13 decreases.

[0043] In one embodiment, the headphones typically include two earcup devices 20, namely a first earcup device 21 and a second earcup device 22. The first earcup device 21 is located on one side of the headband device 10, and the second earcup device 22 is located on the other side of the headband device 10. One of the first earcup device 21 and the second earcup device 22 corresponds to the user's left ear, and the other corresponds to the user's right ear.

[0044] Correspondingly, the headband device 10 includes a first sliding arm 131 and a second sliding arm 132. The first sliding arm 131 is connected to the first earmuff device 21, and the second sliding arm 132 is connected to the second earmuff device 22.

[0045] Please refer to the following: Figure 2 , Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the first part of the headset shown. Wherein, Figure 2 Showing Figure 1 The rotating mechanism 30 corresponds to the second earcup device 22 of the headset shown.

[0046] In one embodiment, the headphones have a folding and storage function. Specifically, the headphones also include a rotating mechanism 30. The earcup device 20 is rotatably connected to the headband support device 10 via the rotating mechanism 30, specifically rotatably connected to the sliding arm 13, thereby realizing the folding and storage function of the headphones.

[0047] It is understood that the first earmuff device 21 and the second earmuff device 22 are rotatably connected to the headband device 10 via different rotating mechanisms 30. In other words, the first earmuff device 21 is rotatably connected to the first sliding arm 131 via one set of rotating mechanisms 30, and the second earmuff device 22 is rotatably connected to the second sliding arm 132 via another set of rotating mechanisms 30. The structures of these two sets of rotating mechanisms 30 can be identical. The following description uses one set of rotating mechanisms 30 as an example only for the purpose of discussion and is not intended to limit the scope of the discussion.

[0048] In one embodiment, the rotating mechanism 30 includes a first rotating component 31 and a second rotating component 32. The first rotating component 31 is rotatably connected to the headband device 10 and is capable of rotating about a first axis X1, and the second rotating component 32 is rotatably connected to the first rotating component 31 and is capable of rotating about a second axis X2.

[0049] Wherein, the first axis X1 is perpendicular to the second axis X2. The first axis X1 is parallel to the plane passing through the wearing area 11 (e.g., Figure 1As shown in the mid-plane α (hereinafter the same), and also parallel to the relative directions of the first earcup device 21 and the second earcup device 22. In the initial state before the headphones are folded and stored, the second axis X2 is perpendicular to the plane passing through the wearing area 11 and the relative directions of the first earcup device 21 and the second earcup device 22.

[0050] In the above manner, after the first rotating component 31 rotates relative to the headband support device 10, it rotates relative to the first rotating component 31 via the second rotating component 32, which can fold and store the ear cup device 20 connected to the second rotating component 32. This makes the headphone in this embodiment have a smaller volume after folding, thus reducing the volume of the headphone after folding.

[0051] The following exemplarily illustrates the folding and storage process of the headphones in this embodiment.

[0052] First, rotate the first rotating component 31 of the rotating mechanism 30 connected to the first earmuff device 21, so that the first earmuff device 21 rotates by a certain angle (e.g., 90°, etc.). Figure 3a As shown; then rotate the first rotating component 31 of the rotating mechanism 30 connected to the second earmuff device 22, so that the second earmuff device 22 rotates in the opposite direction by a certain angle (for example, 90°, etc.), as shown. Figure 3b As shown; then, rotate the second rotating component 32 of the rotating mechanism 30 connected to the first earcup device 21, so that the first earcup device 21 rotates towards the wearing area 11 by a certain angle (e.g., 50°, etc.), as shown. Figure 3c As shown; finally, rotate the second rotating component 32 of the rotating mechanism 30 connected to the second earcup device 22, so that the second earcup device 22 rotates towards the wearing area 11 by a certain angle (e.g., 50°), and finally the first earcup device 21 and the second earcup device 22 are connected, completing the folding and storage process of the headphones, as shown. Figure 3d As shown.

[0053] In one embodiment, the first rotating component 31 and the second rotating component 32 are both located on the side of the headband support device 10 facing the wearing area 11. That is, the rotating mechanism 30 of the headphones in this embodiment is designed on the inner side of the headband support device 10. The rotating mechanism 30 will not significantly affect the product appearance of the headphones in this embodiment, but can improve the product appearance of the headphones.

[0054] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 , Figure 4 yes Figure 2 The diagram shows a partial exploded structure of the headset. Figure 5 yes Figure 1A schematic diagram of the cross-sectional structure of region A of the headset shown.

[0055] In one embodiment, the first rotating assembly 31 includes a first rotating member 311, which is rotatably connected to the second rotating assembly 32. One of the first rotating member 311 and the headband support device 10 is provided with a first rotating shaft 331, and the other is provided with a rotating hole 332, in which the first rotating shaft 331 is rotatably fitted. For detailed structure of the second rotating assembly 32, see [details omitted]. Figure 4 and Figure 5 And as described below.

[0056] The first rotating shaft 331 extends along the first axis X1, enabling the first rotating member 311 to rotate around the first axis X1. The central axis of the first rotating member 311 coincides with the first axis X1, and the rotation of the first rotating member 311 around the first axis X1 is specifically manifested as the first rotating member 311 rotating around its own central axis.

[0057] Figure 4 and Figure 5 The illustration shows a head-mounted support device 10 with a first rotating shaft 331 and a first rotating member 311 with a rotating hole 332. This is for illustrative purposes only and is not intended to be limiting. Specifically, the first rotating shaft 331 is located on the sliding arm 13.

[0058] Furthermore, please refer to the following: Figure 6 The head-mounted support device 10 is provided with at least two fixing parts 133, which are distributed sequentially at intervals along the circumference of the first axis X1, and a guide groove 134 is formed between adjacent fixing parts 133. Figure 6 The illustration shows a head-mounted support device 10 with two fixing parts 133, each of which forms a guide groove 134 on its two sides. This is for illustrative purposes only and is not intended to be limiting.

[0059] The outer peripheral surface of the first rotating member 311 is provided with a rotating part 312. The first rotating assembly 31 also includes a fixing member 313, which presses the rotating part 312 into the guide groove 134. As the first rotating member 311 rotates, the rotating part 312 can move along the guide groove 134, and when the rotating part 312 abuts against the fixing part 133, it restricts the first rotating member 311 from rotating further.

[0060] For example, corresponding Figure 6 In the case where the head-mounted support device 10 shown has two guide grooves 134, the outer peripheral surface of the first rotating member 311 in this embodiment has two rotating parts 312, one rotating part 312 is located in one of the guide grooves 134, and the other rotating part 312 is located in the other guide groove 134.

[0061] In this embodiment, the rotating part 312 is pressed into the guide groove 134 by the fixing member 313, which can fix the first rotating part 311 to the headband support device 10 and prevent the first rotating part 311 from detaching from the headband support device 10. Furthermore, the maximum rotation angle of the first rotating part 311 is limited by the cooperation of the rotating part 312 and the fixing member 133, making the controllability of the rotating mechanism 30 stronger and reducing the user's burden. The maximum rotation angle of the first rotating part 311 is as follows: Figure 6 The mid-angle θ1 is shown.

[0062] Optionally, the fastener 313 and the fixing part 133 can be fixedly connected by fasteners such as screws and bolts, which is not limited here.

[0063] Furthermore, the first rotating assembly 31 also includes a first damping element 314. The first damping element 314 is sandwiched between the first rotating member 311 and the headband device 10 to prevent relative rotation between the first rotating member 311 and the headband device 10. The first damping element 314 may be an elastic structure. When the first damping element 314 sandwiched between the first rotating member 311 and the headband device 10 is in a compressed state, the elastic restoring force provided by the first damping element 314 is converted into frictional force between it and the first rotating member 311 and the headband device 10 to prevent relative rotation between the first rotating member 311 and the headband device 10.

[0064] Since the damping force provided by the first damping element 314 is relatively small, the user can drive the first rotating element 311 to rotate by slightly increasing the force. The first damping element 314 can provide a damping feel during the process of the user driving the first rotating element 311 to rotate, which also helps to improve the controllability of the rotating mechanism 30.

[0065] Optionally, the first damping element 314 extends around the first axis X1 and is sleeved on the outer periphery of the first rotating shaft 331.

[0066] Furthermore, the first rotating assembly 31 also includes a connector 315, through which the first rotating member 311 is connected to the second rotating assembly 32. One of the first rotating member 311 and the connector 315 is provided with a fixing groove 3161, and the other is provided with a fixing protrusion 3162. The fixing protrusion 3162 is embedded in the fixing groove 3161 to restrict the relative rotation between the first rotating member 311 and the connector 315, so that the rotation of the first rotating member 311 can synchronously drive the connector 315 and the connected second rotating assembly 32 to rotate around the first axis X1.

[0067] Figure 4 The illustration shows a case where the first rotating member 311 has a fixing groove 3161 and the adapter 315 has a fixing protrusion 3162. This is only an example and is not intended to limit the scope of the illustration.

[0068] Furthermore, one of the first rotating member 311 and the adapter 315 is provided with a slot 3171 extending around the first axis X1, and the other is provided with a locking block 3172. The locking block 3172 is embedded in the slot 3171 to restrict the adapter 315 from separating from the first rotating member 311.

[0069] Figure 4 and Figure 5 The illustration shows a case where the first rotating member 311 is provided with a locking block 3172 and the adapter 315 is provided with a locking groove 3171, and the fixing groove 3161 on the first rotating member 311 is located at the locking block 3172. This is only an example and is not intended to limit the scope of the illustration.

[0070] In one embodiment, the second rotating assembly 32 includes a ball shaft 321 and a second rotating shaft 322. The ball shaft 321 includes a connected spherical portion 323 and a shaft portion 324. The spherical portion 323 is shaped like a sphere, and the shaft portion 324 is shaped like a rod. The spherical portion 323 is rotatably disposed on the first rotating assembly 31 via the second rotating shaft 322, specifically, the spherical portion 323 is disposed in the aforementioned adapter 315 via the second rotating shaft 322. The shaft portion 324 is connected to the earmuff device 20.

[0071] The second rotation shaft 322 extends along the second axis X2. In other words, the central axis of the second rotation shaft 322 coincides with the second axis X2. The spherical part 323 rotates around the second rotation shaft 322, causing the spherical shaft 321 to rotate around the second axis X2, thereby driving the ear cup device 20 to rotate.

[0072] Furthermore, the first rotating assembly 31 includes a connector 315. The connector 315 has a receiving cavity 3151. A spherical portion 323 is disposed in the receiving cavity 3151 and is interference-fitted with the receiving cavity 3151. The interference fit between the spherical portion 323 and the receiving cavity 3151 can prevent relative rotation between the spherical portion 323 and the connector 315.

[0073] By appropriately setting the degree of interference fit between the ball portion 323 and the receiving cavity 3151, the frictional resistance between the ball portion 323 and the adapter 315 is not excessive, allowing the user to drive the ball portion 323 to rotate with a slight increase in force. Therefore, the interference fit between the ball portion 323 and the receiving cavity 3151 provides a damping feel during the user's rotation of the ball portion 323, which helps improve the controllability of the rotating mechanism 30.

[0074] Furthermore, the adapter 315 includes a fastening housing 3152, a first sub-part 3153, and a second sub-part 3154. The first sub-part 3153 and the second sub-part 3154 are mated to form a receiving cavity 3151, and the fastening housing 3152 surrounds the outer periphery of the first sub-part 3153 and the second sub-part 3154. In this embodiment, the fastening housing 3152 improves the bonding strength between the first sub-part 3153 and the second sub-part 3154 to ensure an interference fit between the spherical part 323 and the first sub-part 3153 and the second sub-part 3154, that is, to ensure an interference fit between the spherical part 323 and the receiving cavity 3151.

[0075] Furthermore, the fastening housing 3152 can be made of metal, which gives it sufficient fastening force to ensure a tight fit between the first sub-part 3153 and the second sub-part 3154. In addition, the fastening housing 3152 can also have a metallic appearance, which helps to improve the product appearance of the headphones in this embodiment.

[0076] Furthermore, the outer peripheral surface of the sphere portion 323 is provided with a first rotating groove 325 extending around the second axis X2. The first rotating member 311 of the first rotating assembly 31 is provided with a first rotating protrusion 318. The first rotating protrusion 318 is embedded in the first rotating groove 325.

[0077] As the spherical portion 323 rotates, the first rotating protrusion 318 can move within the first rotating groove 325. When the first rotating protrusion 318 abuts against both ends of the first rotating groove 325 (the two ends of the first rotating groove 325 in the circumferential direction along the second axis X2), the first rotating protrusion 318 and the first rotating groove 325 cooperate to limit the maximum rotation angle of the spherical portion 323, making the rotation mechanism 30 more controllable and reducing the user's burden. The maximum rotation angle of the spherical portion 323 is as follows: Figure 5 The median angle θ2 is shown.

[0078] Please refer to the following: Figure 7 , Figure 7 yes Figure 1 A schematic diagram of the cross-sectional structure of region B of the headset shown.

[0079] In one embodiment, the earcup device 20 includes an earcup body 23, a second rotating member 24, and an elastic member 25. The earcup body 23 is used to output audio information to a user. The second rotating member 24 is rotatably connected to the earcup body 23 and is capable of rotating about a third axis X3. The third axis X3 is parallel to the second axis X2.

[0080] The shaft portion 324 passes through the second rotating member 24, and the shaft portion 324 and the earcup body 23 are connected by an elastic member 25. The elastic member 25 is used to make the earcup body 23 tend to rotate relative to the shaft portion 324 toward the wearing area 11. In this way, when the user wears the headphones of this embodiment, the earcup body 23 tends to rotate toward the wearing area 11, so that the earcup body 23 fits tightly against the user's ear, which helps to reduce audio leakage and thus improves the user's listening experience.

[0081] Furthermore, the elastic member 25 can be moved away from the ball portion 323 relative to the second rotating member 24. At this time, the elastic member 25 is located on the side of the shaft portion 324 facing the wearing area 11, such as... Figure 7 As shown. When a user wears the headphones of this embodiment, the ball portion 323 rotates about the second axis X2 relative to the earcup body 23 in a direction away from the wearing area 11, so that the shaft portion 324 compresses the elastic member 25. At this time, the elastic restoring force provided by the elastic member 25 makes the earcup body 23 tend to rotate toward the wearing area 11.

[0082] Of course, in other embodiments of this application, the elastic element 25 may also be located on the side of the shaft portion 324 away from the wearing area 11. When the user wears the headphones of this embodiment, the ball portion 323 rotates about the second axis X2 relative to the earcup body 23 in a direction away from the wearing area 11, causing the shaft portion 324 to stretch the elastic element 25. At this time, the elastic restoring force provided by the elastic element 25 can also make the earcup body 23 tend to rotate towards the wearing area 11. Furthermore, the elastic element 25 may also be close to the ball portion 323 relative to the second rotating member 24. By reasonably selecting the position of the elastic element 25, the elastic restoring force of the elastic element 25 can also be used to make the earcup body 23 tend to rotate towards the wearing area 11. This is not limited here.

[0083] Optionally, the elastic element 25 can be a spring or the like, which is not limited here.

[0084] In one embodiment, the shaft portion 324 passes through the second rotating member 24 and is rotatable about a fourth axis X4. The fourth axis X4 coincides with the central axis of the shaft portion 324; therefore, the rotation of the shaft portion 324 about the fourth axis X4 specifically manifests as the shaft portion 324 rotating about its own central axis. The fourth axis X4 is also perpendicular to the second axis X2 and the third axis X3.

[0085] In this way, the earcup device 20 is allowed to rotate relative to the ball joint 321. When the user hangs the headphones of this embodiment around their neck, the user can rotate the earcup device 20 appropriately, which can prevent the earcup device 20 from pressing against the user's chin and help ensure the wearing comfort of the headphones of this embodiment in different situations.

[0086] Furthermore, please refer to the following: Figure 8 The second rotating member 24 is provided with a second rotating groove 241 extending around the fourth axis X4, and the shaft portion 324 is provided with a second rotating protrusion 326. The second rotating protrusion 326 is embedded in the second rotating groove 241.

[0087] As the shaft portion 324 rotates, the second rotating protrusion 326 can move within the second rotating groove 241. When the second rotating protrusion 326 abuts against both ends of the second rotating groove 241 (the two ends of the second rotating groove 241 in the circumferential direction along the fourth axis X4), the second rotating protrusion 326 and the second rotating groove 241 cooperate to limit the maximum rotation angle of the shaft portion 324, making the rotation of the earmuff device 20 more controllable and helping to reduce the user's burden.

[0088] Furthermore, such as Figure 4 and Figure 7 As shown, the earmuff device 20 also includes a second damping member 26. The second damping member 26 is sandwiched between the second rotating member 24 and the shaft portion 324 to prevent relative rotation between the second rotating member 24 and the shaft portion 324. The second damping member 26 can be an elastic structure. When the second damping member 26 sandwiched between the second rotating member 24 and the shaft portion 324 is in a compressed state, the elastic restoring force provided by the second damping member 26 is converted into frictional force between it and the second rotating member 24 and the shaft portion 324 to prevent relative rotation between the second rotating member 24 and the shaft portion 324.

[0089] Because the damping force provided by the second damping element 26 is relatively small, the user can easily drive the relative rotation between the second rotating element 24 and the shaft portion 324 by slightly increasing the force applied. The second damping element 26 can provide a damping feel during the user's rotation of the earcup device 20, which also helps to improve the controllability of the rotation of the earcup device 20.

[0090] Optionally, the second damping element 26 extends around the fourth axis X4 and is sleeved on the outer periphery of the shaft portion 324.

[0091] Please see Figure 1 and Figure 9 , Figure 9 yes Figure 1 A schematic diagram of the cross-sectional structure of region C of the headset shown.

[0092] In one embodiment, the headband device 10 further includes a first roller assembly 14 and a second roller assembly 15. The first roller assembly 14 is disposed on the side of the sliding arm 13 facing the wearing area 11, and the second roller assembly 15 is disposed on the side of the sliding arm 13 away from the wearing area 11, with both the rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 abutting against the sliding arm 13. Both the rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 are capable of rolling with the sliding arm 13, that is, both the rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 are capable of rolling as the sliding arm 13 slides.

[0093] In this embodiment, the sliding arm 13 of the headset is abutted on both sides by rollers, which reduces the fit clearance at the position of the sliding arm 13. In this embodiment, it can even achieve zero fit clearance, thus reducing the degree of wobbling of the sliding arm 13 and improving the stroke accuracy of the sliding arm 13. Furthermore, the rollers of the first roller assembly 14 and the second roller assembly 15 can both roll with the sliding arm 13. The rolling friction provided by the rollers makes the resistance encountered by the sliding arm 13 during the sliding process small, which helps to ensure that the sliding arm 13 slides smoothly.

[0094] In existing headphones, the sliding arm slides within a groove in the headband's mounting bracket. To ensure smooth sliding, the groove size is often larger than the thickness of the sliding arm, resulting in a significant clearance between the sliding arm and the headband mounting bracket, typically reaching 0.3mm. This undoubtedly exacerbates the sliding arm's wobble and affects its stroke accuracy. Furthermore, if existing headphones aim for a smaller clearance, such as zero clearance, unavoidable errors in molding and assembly processes significantly reduce the smoothness of the sliding arm's movement. In this embodiment, the headphones use rollers to abut against both sides of the sliding arm 13, minimizing the clearance at the sliding arm 13's location. This, in turn, minimizes the wobble of the sliding arm 13 and improves its stroke accuracy while ensuring smooth sliding.

[0095] In one embodiment, the orthographic projection of the roller of the first roller assembly 14 onto the reference plane is the same as the projection of the roller of the second roller assembly 15 onto the reference plane (e.g., ...). Figure 9 The reference plane is superimposed on the orthographic projection of the mid-plane β (hereinafter the same). The reference plane extends along the sliding arm 13 and is perpendicular to the relative direction of the first roller assembly 14 and the second roller assembly 15. The reference plane is also perpendicular to the plane passing through the wearing area 11.

[0096] In other words, the rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 abut against the two surfaces of the sliding arm 13 at the same position facing and away from the wearing area 11. The rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 can stably restrict the sliding arm 13, prevent the sliding arm 13 from shaking, and further reduce the degree of shaking of the sliding arm 13 and improve the stroke accuracy of the sliding arm 13.

[0097] Of course, in other embodiments of this application, the rollers of the first roller assembly 14 and the rollers of the second roller assembly 15 may also abut against different positions of the sliding arm 13, which is not limited here.

[0098] Please refer to the following: Figure 10 and Figure 11 , Figure 10 yes Figure 9 The diagram shown is a structural schematic of the headphones facing the wearing area. Figure 11 yes Figure 9 The diagram shows a structural schematic of the headphones on the side opposite to the wearing area. The first roller assembly 14 and the second roller assembly 15 of embodiments of this application are described below by way of example.

[0099] The first roller assembly 14 includes a first roller 141 and a second roller 142. The first roller 141 and the second roller 142 are along a first direction (e.g., ...). Figure 10 and Figure 11 (As indicated by the middle arrow Y1, the same below) are spaced apart from each other. The second roller assembly 15 includes a third roller 151 and a fourth roller 152, which are also spaced apart from each other along a first direction. The first direction is perpendicular to the plane passing through the wearing area 11 and is also parallel to the aforementioned reference plane.

[0100] The orthographic projection of the first roller 141 on the reference plane overlaps with the orthographic projection of the third roller 151 on the reference plane, and the orthographic projection of the second roller 142 on the reference plane overlaps with the orthographic projection of the fourth roller 152 on the reference plane.

[0101] Please refer to the following: Figure 12 and Figure 13 , Figure 12 yes Figure 1 The diagram shows the structure of the second part of the headset. Figure 13 yes Figure 12 The diagram shows a partial exploded structure of a pair of headphones. Figure 12 The structure of the headband device 10 corresponding to the part connected to the first earmuff device 21 is shown.

[0102] In one embodiment, the headband support device 10 further includes a roller bracket 16, which is detachably mounted on the headband fixing bracket 12. The first roller 141 and the second roller 142 are rotatably connected to the roller bracket 16. In other words, the rollers located on the side of the sliding arm 13 facing the wearing area 11 are detachably designed via the roller bracket 16, facilitating the assembly of the sliding arm 13 and the rollers. Specifically, the rollers of the second roller assembly 15 are first assembled onto the headband fixing bracket 12, then the sliding arm 13 is assembled, and finally, the rollers of the first roller assembly 14 are assembled onto the headband fixing bracket 12 via the roller bracket 16. Furthermore, the roller bracket 16 is located on the side of the sliding arm 13 facing the wearing area 11, i.e., the roller bracket 16 is located inside the headband fixing bracket 12, thus preventing the roller bracket 16 from affecting the appearance of the headphone in this embodiment.

[0103] Optionally, in this embodiment, the roller is rotatably mounted on the headgear device 10 via a roller shaft. To facilitate the assembly of the roller and roller shaft and to ensure that the roller can roll with the sliding arm 13, preferably the first roller 141 is located on one side of the roller bracket 16 in the first direction, and the second roller 142 is located on the other side of the roller bracket 16 in the first direction.

[0104] Furthermore, the headband support device 10 also includes a fixing pin 161. The headband fixing bracket 12 is provided with a first fixing hole 121, and the roller bracket 16 is provided with a second fixing hole 162. After the first roller 141 and the second roller 142 are assembled to the headband fixing bracket 12 through the roller bracket 16, the fixing pin 161 passes through the first fixing hole 121 and the second fixing hole 162 to fix the roller bracket 16 to the headband fixing bracket 12.

[0105] In other words, in this embodiment, the roller bracket 16 is connected to the head-mounted support 12 through the roller shafts of the first roller 141 and the second roller 142, and is also connected to the head-mounted support 12 through the fixing pin 161, thereby realizing the detachable design of the roller bracket 16.

[0106] Optionally, the roller shaft and the fixing pin 161 can both be made of stainless steel or other materials, and there is no limitation on this.

[0107] Furthermore, such as Figure 10 As shown, the roller bracket 16 cooperates with the headgear fixing bracket 12 to form the first limiting part 143 and the second limiting part 144. The first roller ( Figure 10 Not shown in the diagram; see details for specific structural information. Figure 13 The first roller 141 (marked 141) is provided in the first limiting part 143 to limit the position of the first roller 141 in the first direction. The second roller ( Figure 10 Not shown in the diagram; see details for specific structural information. Figure 13The first roller 141 (marked 142) is provided in the second limiting part 144 to limit the position of the second roller 142 in the first direction. In this way, the position of the first roller 141 and the second roller 142 can be prevented from changing, thereby avoiding affecting the limiting effect of the first roller 141 and the second roller 142 on the swaying of the sliding arm 13.

[0108] Similarly, such as Figure 11 As shown, the head-mounted support 12 has a third limiting part 153 and a fourth limiting part 154 on the side opposite to the wearing area 11. The third roller 151 is provided in the third limiting part 153 to limit the position of the third roller 151 in the first direction, and the fourth roller 152 is provided in the fourth limiting part 154 to limit the position of the fourth roller 152 in the first direction.

[0109] Furthermore, the head-mounted support 12 is provided with a groove 122, and a sliding arm 13 is disposed in the groove 122. The groove 122 extends around the wearing area 11, and the sliding arm 13 can slide along the groove 122 in the groove, that is, the sliding arm 13 can slide around the wearing area 11.

[0110] Please refer to the following: Figure 14a and Figure 14b , Figure 14a and Figure 14b The cross-sectional structure of the left half of the headgear device 10 is shown.

[0111] The sliding arm 13 has a protruding abutment 135 on its surface facing the wearing area 11. The abutment 135 can move with the sliding arm 13 to restrict the sliding arm 13 from sliding further after the abutment 135 abuts against the roller bracket 16.

[0112] By means of the above method, when the abutment portion 135 abuts against the roller bracket 16, the sliding arm 13 is restricted from further sliding, thus preventing the sliding arm 13 from sliding out of the groove 122. Furthermore, both the roller bracket 16 and the abutment portion 135 are located on the side of the headband fixing bracket 12 facing the wearing area 11, that is, both are located inside the headband fixing bracket 12. This avoids affecting the appearance of the headphones of this embodiment, making the appearance of the headphones of this embodiment more competitive.

[0113] Furthermore, the head-mounted fixation bracket 12 is positioned along the second direction (e.g., Figure 14a(As indicated by the middle arrow Y2, the same below) Surrounding the wearing area 11, the roller bracket 16 is located at the end of the headband fixing bracket 12 in the second direction. In this way, the roller bracket 16 can cooperate with the abutment part 135 on the sliding arm 13, restricting the sliding arm 13 when it is about to disengage from the headband fixing bracket 12. This not only prevents the sliding arm 13 from sliding out of the groove 122, but also ensures that the sliding arm 13 has sufficient maximum extension, which is beneficial for adapting to the wearing conditions of more users and ensuring that different users can adjust the earcup device 20 to a suitable position for wearing.

[0114] Please see Figure 1 , Figure 15 and Figure 16 , Figure 15 yes Figure 1 The diagram shows the structure of the fourth part of the headset. Figure 16 yes Figure 15 The diagram shows a partial exploded structure of a pair of headphones. Figure 15 Showing Figure 1 The structure of the head-mounted support device 10 facing the wearing area 11.

[0115] The following description uses the above-mentioned over-ear headphones, including the first earcup device 21 and the second earcup device 22, and the headband device 10, including the first sliding arm 131 and the second sliding arm 132, as an example. This is only for the purpose of discussion and is not intended to limit the scope of the discussion.

[0116] In one embodiment, the first sliding arm 131 is connected to the first earmuff device 21 and is located on one side of the wearing area 11, and the second sliding arm 132 is connected to the second earmuff device 22 and is located on the other side of the wearing area 11. Both the first sliding arm 131 and the second sliding arm 132 are slidably disposed on the headband fixing bracket 12.

[0117] The headgear device 10 also includes a first rack 41, a second rack 42, and a gear transmission mechanism (including the first gear assembly 43 and the second gear assembly 44 hereinafter referred to as the first gear assembly 43). The first rack 41 is connected to the first sliding arm 131, and the second rack 42 is connected to the second sliding arm 132. The first rack 41 and the second rack 42 are also respectively connected to the gear transmission mechanism. Sliding of either the first sliding arm 131 or the second sliding arm 132 can drive the other to slide synchronously in opposite directions.

[0118] In this manner, the first sliding arm 131 and the second sliding arm 132 slide synchronously, ensuring that the extension amounts of the first sliding arm 131 and the second sliding arm 132 remain consistent at any given time. Users can easily adjust the extension amounts of the first sliding arm 131 and the second sliding arm 132, facilitating the synchronous adjustment of the first earcup device 21 and the second earcup device 22 to a suitable position for wearing, thus reducing the user's burden. Furthermore, the rack and pinion transmission mechanism precisely controls the extension amounts of the first sliding arm 131 and the second sliding arm 132, effectively preventing significant differences in their extension amounts.

[0119] Furthermore, since the headband fixing bracket 12 is typically curved due to its arrangement around the wearing area 11, the first rack 41 and the second rack 42 are also typically curved within the headband fixing bracket 12. In this embodiment, the first rack 41 and the second rack 42 are located on the same side of the gear transmission mechanism, which helps to ensure that the bending amount of the first rack 41 and the second rack 42 are consistent, thereby ensuring stable meshing between the first rack 41 and the second rack 42 and the gear transmission mechanism, and helping to ensure the stability of the movement of the first sliding arm 131 and the second sliding arm 132.

[0120] In existing headphones, the first and second racks are located on the upper and lower sides of the gear transmission mechanism, respectively. For example, the first rack is located on the side of the gear transmission mechanism away from the wearing area, and the second rack is located on the side of the gear transmission mechanism facing the wearing area. Because the bending amounts of the first and second racks, which are distributed vertically, are prone to differ, it is not conducive to ensuring that the bending amounts of the first and second racks are consistent. This can easily lead to unstable meshing between the first and second racks and the gear transmission mechanism, and consequently, unstable movement of the first and second sliding arms.

[0121] Optionally, the first rack 41 and the second rack 42 are spaced apart from each other in the first direction, such that the first rack 41 and the second rack 42 can be disposed on the same side of the gear transmission mechanism. Furthermore, in the case where the headband fixing bracket 12 is provided with a sliding groove 122, in this embodiment, the first sliding arm 131, the second sliding arm 132, the first rack 41, and the second rack 42 can all be slidably disposed in the sliding groove 122.

[0122] In one embodiment, the design of headphones typically requires a certain amount of space to be reserved on the side of the headband 12 facing the wearing area 11 for a cushioning structure, preventing the headband 12 from directly contacting the user's head and ensuring user comfort. In this embodiment, the first rack 41 and the second rack 42 are located on the side of the gear transmission mechanism away from the wearing area 11, that is, the gear transmission mechanism is closer to the wearing area 11 than the first rack 41 and the second rack 42. This embodiment can utilize the space for the cushioning structure to house the gear transmission mechanism, which does not occupy additional space, thus improving the overall space utilization of the headphones. This allows for a smaller thickness in the design of the headband device 10, resulting in a better visual effect for the headphones in this embodiment.

[0123] Of course, since the gear transmission mechanism in this embodiment is small in size, it will not take up too much space originally used for setting the buffer structure. The headphones can still be equipped with sufficient buffer structure to ensure the user's wearing comfort.

[0124] Optionally, the first rack 41 and the second rack 42 are positioned closer to the wearing area 11 relative to the first sliding arm 131 and the second sliding arm 132. Specifically, the first rack 41 is positioned closer to the wearing area 11 relative to the first sliding arm 131, and the second rack 42 is positioned closer to the wearing area 11 relative to the second sliding arm 132.

[0125] In one embodiment, the gear transmission mechanism includes a first gear assembly 43 and a second gear assembly 44 that are driveably connected to each other. The gear of the first gear assembly 43 meshes with a first rack 42, and the gear of the second gear assembly 44 meshes with a second rack 41. As either the first sliding arm 131 or the second sliding arm 132 slides, the gear of the first gear assembly 43 rotates in the opposite direction to the gear of the second gear assembly 44, such that sliding either the first sliding arm 131 or the second sliding arm 132 can drive the other to slide synchronously in opposite directions.

[0126] Specifically, the gear transmission mechanism also includes a main bevel gear 45. The first gear assembly 43 includes a first auxiliary bevel gear 431 and a first spur gear 432, which are coaxially arranged and can rotate synchronously. The second gear assembly 44 includes a second auxiliary bevel gear 441 and a second spur gear 442, which are coaxially arranged and can rotate synchronously. The first auxiliary bevel gear 431 and the second auxiliary bevel gear 441 are located on both sides of the main bevel gear 45, and both mesh with the main bevel gear 45.

[0127] When the first sliding arm 131 slides, the first rack 41 can drive the first auxiliary bevel gear 431 to rotate through the first spur gear 432, which in turn drives the main bevel gear 45 to rotate. This, in turn, drives the second auxiliary bevel gear 441 to rotate in the opposite direction through the main bevel gear 45, which in turn drives the second rack 42 to slide in the opposite direction to the movement direction of the first rack 41 through the second spur gear 442. In other words, the second sliding arm 132 and the first sliding arm 131 slide synchronously towards or away from each other.

[0128] For example, such as Figure 15 As shown, the first sliding arm 131 slides away from the gear transmission mechanism, causing the first rack 41 to move. The first rack 41 drives the first auxiliary bevel gear 431 and the first spur gear 432 to rotate clockwise, and through the main bevel gear 45 drives the second auxiliary bevel gear 441 and the second spur gear 442 to rotate counterclockwise. The second spur gear 442 drives the second rack 42 to move, ultimately causing the second sliding arm 132 to slide away from the gear transmission mechanism in sync.

[0129] Furthermore, the gear transmission mechanism also includes a gear shaft 46. A first auxiliary bevel gear 431 and a first spur gear 432 are mounted on the gear shaft 46 and are rotatable relative to the gear shaft 46. A second auxiliary bevel gear 441 and a second spur gear 442 are mounted on the gear shaft 46 and are rotatable relative to the gear shaft 46.

[0130] In this manner, the first auxiliary bevel gear 431, the first spur gear 432, the second auxiliary bevel gear 441, and the second spur gear 442 are coaxially arranged through the gear shaft 46, and all of them can rotate relative to the gear shaft 46. That is, the rotation of the first auxiliary bevel gear 431 and the first spur gear 432 is independent of and does not affect the rotation of the second auxiliary bevel gear 441 and the second spur gear 442, which helps to simplify the structure of the gear transmission mechanism.

[0131] Optionally, the gear shaft 46 is fixed to the headgear fixing bracket 12, that is, the gear shaft 46 cannot rotate, so that the first auxiliary bevel gear 431, the first spur gear 432, the second auxiliary bevel gear 441 and the second spur gear 442 can all rotate relative to the gear shaft 46.

[0132] Please refer to the following: Figures 14a-14b and Figures 17a-17b , Figures 17a-17b yes Figure 1 The diagram shows a cross-sectional view of the fifth part of the headset.

[0133] In one embodiment, the headband fixing bracket 12 is provided with a first limiting groove group 124 and a second limiting groove group 125. The first limiting groove group 124 and the second limiting groove group 125 each include at least two limiting grooves 126 distributed sequentially along the direction surrounding the wearing area 11.

[0134] The headband support device 10 also includes a first spring 171 and a second spring 172. The first spring 171 is connected to the first sliding arm 131, and the second spring 172 is connected to the second sliding arm 132. The first spring 171 can selectively engage with different limiting slots 126 of the first limiting slot group 124 to fix the relative position between the first sliding arm 131 and the headband fixing bracket 12, such as... Figure 14b As shown. The second spring piece 172 can selectively engage with different limiting slots 126 of the second limiting slot group 125 to fix the relative position between the second sliding arm 132 and the headgear fixing bracket 12, as shown. Figure 17b As shown.

[0135] As the first sliding arm 131 slides relative to the headband fixing bracket 12, the first spring piece 171 is respectively embedded in different limiting slots 126 of the first limiting slot group 124. When the first sliding arm 131 stops sliding, the first spring piece 171 cooperates with its currently embedded limiting slot 126 to fix the relative position between the first sliding arm 131 and the headband fixing bracket 12. Similarly, as the second sliding arm 132 slides relative to the headband fixing bracket 12, the second spring piece 172 is respectively embedded in different limiting slots 126 of the second limiting slot group 125. When the second sliding arm 132 stops sliding, the second spring piece 172 cooperates with its currently embedded limiting slot 126 to fix the relative position between the second sliding arm 132 and the headband fixing bracket 12.

[0136] In this way, when adjusting the extension amount of the first sliding arm 131 and the second sliding arm 132, the user can keep the current extension amount of the first sliding arm 131 and the second sliding arm 132 at any time, which can facilitate the user's adjustment operation and help reduce the user's burden.

[0137] Furthermore, the first sliding arm 131 is provided with a first abutment portion 1351 near the first spring piece 171. The second sliding arm 132 is provided with a second abutment portion 1352 near the second spring piece 172. The headband support device 10 also includes a first roller bracket 163 corresponding to the first abutment portion 1351 and a second roller bracket 164 corresponding to the second abutment portion 1352, so as to restrict the first sliding arm 131 from disengaging from the headband fixing bracket 12 when the first abutment portion 1351 abuts against the first roller bracket 163, and to restrict the second sliding arm 132 from disengaging from the headband fixing bracket 12 when the second abutment portion 1352 abuts against the second roller bracket 164.

[0138] In this embodiment, the first sliding arm 131 is provided with a first abutting part 1351 and a first roller bracket 163 to prevent the first sliding arm 131 from detaching from the head-mounted fixing bracket 12, and the second sliding arm 132 is provided with a second abutting part 1352 and a second roller bracket 164 to prevent the second sliding arm 132 from detaching from the head-mounted fixing bracket 12.

[0139] Furthermore, in this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements.

[0140] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
