Description

Technical Field

[0001] This application relates to the field of headphone technology, and more particularly to a headband and headphones. Background Technology

[0002] Headset-mounted devices, such as headphones, are popular due to their ease of use. A typical headset includes a headband and functional accessories attached to the end of the headband. The headband usually consists of multiple joint structures. Because headbands are generally quite large, they are often designed to be retractable. When not in use, the joint structures can be moved to store the functional accessories, reducing the overall size of the headset for easier storage and portability.

[0003] However, in related technologies, when the headband is in a stowed state, the joint structure is prone to loosening due to factors such as shaking. Utility Model Content

[0004] This application provides a headband and headphones that increase the rotational resistance of the joint structure, thereby preventing the joint structure from becoming loose or unfolded due to factors such as shaking, thus making the headband more stable and reliable to store.

[0005] In a first aspect, this application provides a headband, including a frame and a rotating assembly. The frame is arc-shaped and includes a plurality of joint structures connected in sequence, with adjacent joint structures rotatably connected via the rotating assembly. The rotating assembly includes:

[0006] A first rotating shaft is located on one side of the frame, and the axis of the first rotating shaft is parallel to the axis of the frame.

[0007] The first connector is connected to the first rotating shaft and to one of the two adjacent joint structures;

[0008] The second connector is rotatably connected to the first pivot and to another joint structure in a pair of adjacent joint structures, the two adjacent joint structures rotating about the first pivot to allow the frame to switch between a stowed state and an unfolded state; and,

[0009] A first damping component, sleeved on the first rotating shaft and abutting against the second connecting member, is used to provide rotational resistance for the joint structure.

[0010] Secondly, this application provides a headset including two earphone units and a headband, wherein the two earphone units are respectively connected to both ends of the frame.

[0011] The beneficial effects of this application are as follows: When the user holds the frame and rotates the joint structure to bring the frame to a retracted state, the first damping component provides rotational resistance to the joint structure, requiring a certain driving force to rotate. This prevents the joint structure from becoming loose due to shaking or other factors. The frame then rotates outwards towards the headband, restoring it to its unfolded state. This makes the headband's retraction more stable and reliable. Furthermore, the joint structure can be suspended at any position along its rotational trajectory, allowing it to adjust to a suitable position according to head size and remain stably suspended when the headband is worn. This ensures a tighter fit between the headphone unit connected to the headband and the ear, while also preventing the headband from becoming loose during use. During the process, the joint structure wobbles; in addition, in this application, since the first pivot is located on the side of the frame, and the frame and the second joint structure are respectively connected to the first pivot through additional first and second connectors, the joint structure has a larger range of rotation, thereby allowing the joint structure to rotate at a larger angle toward the inside of the headband, which in turn makes the headband smaller in volume when the frame is in the storage state. Furthermore, the first damping component can also be located on the side of the frame, making it easier for staff to adjust the first damping component, so that the first damping component can provide suitable rotational resistance for the joint structure, allowing the joint structure to be suspended at any position on its rotational trajectory while being able to rotate smoothly.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] This application provides a headband and headphones to solve the problem in the related art where, when the second joint structure is in the stored state, it is easily restored to the unfolded state due to factors such as vibration, causing inconvenience to the user.

[0025] Firstly, this application provides a headband, such as Figure 1 As shown, the headband includes a frame 10 and a rotating assembly 30. The frame 10 is arc-shaped and includes multiple joint structures 11 connected in sequence. The multiple joint structures 11 are arranged sequentially along the extending direction of the frame 10, and two adjacent joint structures 11 are rotatably connected by the rotating assembly 30. It can be understood that, taking the headband's application in over-ear headphones as an example, combined with... Figure 7 and Figure 8 As shown, the headband can fix the headphone unit 50 on the user's head. The frame 10 is the main structure of the headband and is used to wear it on the user's head. The extension direction of the rotation center line of the joint structure 11 is parallel to the axis of the frame 10. The frame 10 is formed by multiple joint structures 11, and the structures of the multiple joint structures 11 can be the same or different. Specifically, as shown... Figure 2 and Figure 3As shown, the rotating assembly 30 includes a first rotating shaft 31, a first connecting member 32, a second connecting member 33, and a first damping assembly 34.

[0026] Among them, the axial direction of the first rotating shaft 31 (i.e., the length direction of the first rotating shaft 31) is opposite to the axial direction of the frame 10. Figure 1 Parallel in the OO direction; the first connector 32 is connected to the first rotating shaft 31 and to one of the two adjacent joint structures 11; the second connector 33 is rotatably connected to the first rotating shaft 31 and to the other of the two adjacent joint structures 11, and the two adjacent joint structures 11 rotate around the first rotating shaft 31 so that the frame 10 can switch between a retracted state and an unfolded state. It can be understood that, taking the headband application in headphones as an example, when the headband is in use, such as when the headband is worn on the head, the frame 10 is in the unfolded state (e.g., when the headband is in use, such as when the headband is worn on the head). Figure 7 At this time, the headband occupies a large volume of space; when the headband is not needed, the joint structure 11 can be rotated around the axis of the first pivot 31 toward the inside of the headband, so that the frame 10 returns to the storage state, thereby reducing the overall volume of the headband and making the headband more convenient to carry.

[0027] More specifically, the first pivot 31 is located on one side of the frame 10. The first pivot 31 can be located on the inner or outer side of the frame 10. The inner side of the frame 10 refers to the side facing the head when the headband is worn on the head, and the outer side of the frame 10 refers to the side facing away from the head when the headband is worn on the head. The rotating assembly 30 also includes a first damping assembly 34, which is sleeved on the first pivot 31 and abuts against the second connector 33. The first damping assembly 34 is used to provide rotational resistance for the joint structure 11.

[0028] It should be noted that when the user holds the frame 10 and rotates the joint structure 11 to rotate the frame 10 to the retracted state, the first damping component 34 provides rotational resistance to the joint structure 11, so that the joint structure 11 requires a certain driving force to rotate. This prevents the joint structure 11 from rotating outwards due to factors such as shaking, thus preventing the frame 10 from returning to the unfolded state. This makes the retraction of the headband more stable and reliable. Furthermore, the joint structure 11 can be suspended at any position on its rotational trajectory, so that when the headband is worn on the head, the joint structure 11 can be adjusted to a suitable position according to the size of the head and be suspended stably. This allows the headphone unit 50 connected to the headband to fit more closely to the ear, while also preventing the joint structure 11 from shaking during use.

[0029] Furthermore, compared to related technologies where the pivot is located inside the frame 10, the rotation range of the joint structure 11 is limited by the clearance between adjacent joint structures 11, resulting in a very small rotation range. In this application, since the first pivot 31 is located on one side of the frame 10, i.e., the first pivot 31 is located outside the frame 10, and the frame 10 and the joint structure 11 are connected to the first pivot 31 by additional first connector 32 and second connector 33 respectively, the joint structure 11 has a larger rotation range, thereby allowing the joint structure 11 to rotate at a larger angle towards the inside of the headband. This results in a smaller headband volume when the frame 10 is in the folded state. Additionally, the first damping component 34 can also be located on the side of the frame 10, making it easier for staff to adjust the first damping component 34. This allows the first damping component 34 to provide suitable rotational resistance for the joint structure 11, enabling the joint structure 11 to rotate smoothly and to hover at any position on its rotational trajectory.

[0030] Specifically, the first rotating shaft 31 and the rotating assembly 30 can be located inside the frame 10, and the first rotating shaft 31 and the rotating assembly 30 can be hidden inside the frame 10.

[0031] like Figure 4 and Figure 5 As shown, in some embodiments of this application, the second connector 33 includes a rotating part 331 and a hinge part 332. The rotating part 331 is sleeved on the first rotating shaft 31 and rotatably connected to the first rotating shaft 31. The hinge part 332 is connected to the rotating part 331 and the joint structure 11 to connect the rotating part 331 and the joint structure 11.

[0032] The first damping component 34 is sleeved on the first rotating shaft 31 and abuts against the rotating part 331 to provide rotational resistance for the joint structure 11. It is understood that when the rotating part 331 of the second connecting member 33 rotates relative to the first rotating shaft 31, the second connecting member 33 and the first damping component 34 will move relative to each other, thereby generating friction. The rotational friction between the first damping component 34 and the rotating part 331 provides rotational resistance to the rotating part 331, allowing the joint structure 11 to adjust to a suitable position according to the head size and to hover stably.

[0033] In some embodiments, the first damping assembly 34 may further include an adjusting nut 342 and an elastic damping element 343. The adjusting nut 342 is sleeved on the first rotating shaft 31 and threadedly connected to the first rotating shaft 31. The elastic damping element 343 is sleeved on the first rotating shaft 31 and located between the adjusting nut 342 and the rotating part 331. The elastic damping element 343 is used to provide rotational resistance for the joint structure 11. It is understood that when the elastic damping element 343 is in a compressed state, pressure can be applied to the rotating part 331 by the elastic force of the elastic damping element 343, thereby providing rotational resistance to the joint structure 11. The greater the pressure provided by the elastic damping element 343 to the rotating part 331, the greater the rotational resistance experienced by the rotating part 331 and the joint structure 11 when rotating. The adjusting nut 342 is used to adjust the magnitude of the pressure applied by the elastic damping element 343 to the rotating part 331. When the adjusting nut 342 is rotated, the adjusting nut 342 can move axially relative to the first rotating shaft 31, thereby adjusting the degree of compression of the elastic damping element 343, thereby adjusting the magnitude of the pressure applied by the elastic damping element 343 to the rotating part 331, and thus adjusting the magnitude of the rotational resistance experienced by the rotating part 331 and the joint structure 11 when rotating, so that the first damping assembly 34 can provide suitable rotational resistance to the joint structure 11.

[0034] In some embodiments, the first damping assembly 34 further includes a first washer 341a and a second washer 341b. The first washer 341a is sleeved on the first rotating shaft 31 and located between the rotating part 311 and the elastic damping member 343, with both sides of the first washer 341a abutting against the rotating part 311 and the elastic damping member 343, respectively. The second washer 341b is sleeved on the first rotating shaft 31 and located between the adjusting nut 342 and the elastic damping member 343, with both sides of the second washer 341b abutting against the adjusting nut 342 and the elastic damping member 343, respectively. It should be noted that the first washer 341a and the second washer 341b can respectively separate the two ends of the elastic damping member 343 from the rotating part 311 and the adjusting nut 342, thereby preventing the elastic damping member 343 from contacting the rotating part 311 and the adjusting nut 342, thus preventing friction between the rotating part 311 and the elastic damping member 343 during rotation and causing wear of the elastic damping member 343, thereby improving the service life of the elastic damping member 343. At the same time, the elastic damping member 343 can also apply pressure to the rotating part 331 through the first washer 341a.

[0035] The elastic damping element 343 can be a disc spring, which has strong stability. The disc spring can release some potential energy to maintain the required pressure on the rotating part 331. The specific specifications and materials of the disc spring can be selected according to actual needs, and this application does not impose specific restrictions. The specific working principle of the disc spring has been disclosed in related technologies and will not be described in detail here. Of course, in other embodiments, the elastic damping element 343 can also be an elastic element such as a spring sleeve or a rubber block. There can be one, two or more elastic damping elements 343. This application does not impose specific restrictions on the number of elastic damping elements 343.

[0036] See also Figure 4 and Figure 5 As shown, in some embodiments of this application, the first rotating shaft 31 includes a first connecting section 311, and the rotating part 331 is rotatably connected to the first connecting section 311. The peripheral surface of the first connecting section 311 includes a first plane 311a extending along the axial direction of the first rotating shaft 31, and the first plane 311a is parallel to the axis of the first rotating shaft 31. It can be understood that the first plane 311a can be formed by cutting the first rotating shaft 31 after it has been formed into a cylindrical shape, or the first plane 311a can be formed simultaneously when the first rotating shaft 31 is formed. The presence of the first plane 311a makes the cross-section of the first rotating shaft 31 non-circular, which can increase the rotational resistance when the rotating part 331 rotates around the first rotating shaft 31.

[0037] The first plane 311a can be provided in one or more ways. When there are two first planes 311a, the two first planes 311a can be located on both sides of the first rotating shaft 31 and arranged in opposite directions. When there are three or more first planes 311a, the multiple first planes 311a can be arranged circumferentially around the first rotating shaft 31.

[0038] In some embodiments, a limiting part 312 is provided on the first rotating shaft 31, and a rotating part 331 is sandwiched between the limiting part 312 and the first damping component 34, and the rotating part 331 abuts against the limiting part 312. The limiting part 312 can limit the rotating part 331 to prevent the rotating part 331 from sliding along the axial direction of the first rotating shaft 31, so that the first damping component 34 can maintain close contact with the rotating part 331, so as to ensure that the friction between the first damping component 34 and the rotating part 331 is sufficient to make the joint structure 11 hover.

[0039] Specifically, there are two limiting parts 312, which are arranged at an axial interval along the first rotating shaft 31. The first connecting member 32 includes a first connecting part 321 and a second connecting part 322. The first connecting part 321 is located between the two limiting parts 312 and connected to the first rotating shaft 31, so as to provide axial limiting for the first connecting part 321 through the limiting parts 312, preventing the first connecting part 321 from sliding along the axial direction of the first rotating shaft 31, and at the same time, allowing the first connecting part 321 to avoid the rotating part 331, so as to prevent the first connecting part 321 from obstructing the rotation of the rotating part 331. The second connecting part 322 is connected to the first connecting part 321 and the joint structure 11, so as to connect the first connecting part 321 to the joint structure 11. The first connecting part 321 can be fixed to the frame 10 by screws or hot-melt pins that pass through the first connecting part 321 and the first rotating shaft 31 in sequence.

[0040] In some embodiments, there are two second connectors 33 and two first damping components 34. The two second connectors 33 are arranged axially spaced along the first rotating shaft 31, and the two first damping components 34 are arranged axially spaced along the first rotating shaft 31. The two second connectors 33 are located between the two first damping components 34, and the two limiting portions 312 are located between the two second connectors 33. It is understood that the joint structure 11 is rotatably connected to the first rotating shaft 31 via two second connectors 33 arranged axially along the first rotating shaft 31, so that the force on all parts of the joint structure 11 can be more evenly distributed when rotating, preventing the joint structure 11 from tilting and causing rotational jamming. Furthermore, see... Figure 5 As shown, the two second connectors 33 are spaced apart from each other, so that when assembling the first damping assembly 34, the rotating parts 331 of the second connectors 33 can be respectively fitted onto the first rotating shaft 31 from both ends, making the assembly of the second connectors 33 and the first rotating shaft 31 more convenient.

[0041] like Figure 1 As shown, in some embodiments of this application, the plurality of joint structures 11 include a first joint structure 12 and two second joint structures 13, with the two second joint structures 13 located at opposite ends of the first joint structure 12. It should be noted that the first joint structure 12 is the main frame of the frame 10 and is used to be worn on the user's head. The structure and shape of the second joint structure 13 may differ from the first joint structure 12. The second joint structure 20 is used to connect functional accessories such as the headphone unit 60 to the headband, making the connection between the headphone unit 60 and the headband more convenient.

[0042] In some embodiments, the second joint structure 13 and the first joint structure 12 are rotatably connected by a rotating component 30, so that the second joint structure 13 can drive the headphone unit 60 and other functional accessories to rotate, thereby adjusting the position of the functional accessories according to the size of the user's head, making the user more comfortable when using the functional accessories.

[0043] In this embodiment, there is one first joint structure 12. Both ends of the first joint structure 12 are rotatably connected to two second joint structures 13 via rotating components 30. That is, the main structure of the frame 10 is formed by one first joint structure 12, which reduces the number of components in the frame 10 and lowers production costs. Of course, in other embodiments, there can be multiple first joint structures 12, arranged sequentially, with adjacent first joint structures 12 rotatably connected via rotating components 30. Two second joint structures 13 are located at both ends of the multiple first joint structures 12, and each second joint structure 13 is rotatably connected to its adjacent first joint structure 12 via rotating components 30. It is understandable that the first joint structure 12 adjacent to the second joint structure 13 refers to the first joint structure 12 that is closest to the first joint structure 12 among multiple first joint structures 12. All of the first joint structures 12 can rotate, so that when the headband is not needed, the frame 10 can be stored by rotating each of the first joint structures 12, which can further reduce the overall volume of the headband. Furthermore, any two adjacent first joint structures 12 can rotate relative to each other, so that multiple areas of the frame 10 can be stored, thereby greatly reducing the space volume of the frame 10 when it is stored, thus reducing the space volume of the headband and making the headband more convenient to carry.

[0044] In other embodiments, two adjacent first joint structures 12 can be rotatably connected by a rotating assembly 30, and a second joint structure 13 is connected to the adjacent first joint structure 12. By rotating the first joint structure 12, the frame 10 can be switched between a stowed state and an unfolded state. The second joint structure 13 can be fixedly connected to the first joint structure 12 or detachably connected.

[0045] like Figure 6 As shown, in some other embodiments, the frame 10 further includes a second rotating shaft 40, the axis of which is parallel to the axis of the frame 10. The multiple joint structures 11 include multiple first joint structures 12 and two second joint structures 13. The multiple first joint structures 12 are arranged in sequence, and the two second joint structures 13 are located at both ends of the multiple first joint structures 12 respectively.

[0046] In this configuration, two adjacent first joint structures 12 are rotatably connected via a second pivot 40, and a second joint structure 13 is rotatably connected to an adjacent first joint structure 12 via a rotating assembly 30; alternatively, two adjacent first joint structures 12 are rotatably connected via a rotating assembly 30, and a second joint structure 13 is rotatably connected to an adjacent first joint structure 12 via a second pivot 40. It is understood that by rotatably connecting some joint structures 11 solely via a simple second pivot 40, the overall cost and weight of the headband can be reduced.

[0047] Based on the headband described above, this application also provides a headset, such as... Figure 7 and Figure 8 As shown, the headphones include two headphone units 50 and a headband as described in any of the above embodiments, with the two headphone units 50 respectively connected to both ends of the frame 10.

[0048] The headphones can be wired or wireless, one of the two headphone units 50 is the left ear headphone unit, and the other of the two headphone units 50 is the right ear headphone unit. The two headphone units 50 are respectively connected to the two second joint structures 13.

[0049] In some embodiments, the headphone unit 50 is rotatably connected to the frame 10, and the headphone unit 50 rotates relative to the frame 10 to achieve a natural state (e.g., Figure 7 ) and folded state (e.g.) Figure 8 Switch between )

[0050] When the headphone unit 50 is in the retracted state, the frame 10 is also in the retracted state, and the earcups of the two headphone units 50 are in contact.

[0051] It is understandable that when the headphone unit 50 is in its natural state, the frame 10 is in its unfolded state, and the two headphone units 50 are spaced apart, so that the headphones are in the unfolded state and convenient for users to use; when the headphone unit 50 is in the folded state, the overall size of the headphones is smaller, making them convenient for users to carry, and at this time, the friction between the earcups of the two headphone units 50 can be used to prevent the headband from returning to the unfolded state, so that the headband can be stably kept in the folded state.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
