Description

Headbands and headphones

[0001] This application claims priority to Chinese Patent Application No. 2024208805050, filed on April 25, 2024, entitled "Headband and Headphones", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of headphone technology, and in particular to a headband and headphones using the headband. Background Technology

[0003] Headset-style devices, such as headphones, are popular among users due to their ease of wear. Headsets are generally quite large, so some headphones are foldable for easier storage and organization, taking up less space when folded.

[0004] Some headphones include a headband and earphone units connected to both ends of the headband, with the earphone units foldable relative to the headband. However, the folding angle of the earphone units in related technologies is relatively limited, and the connection between the earphone units and the headband is loose, resulting in a poor user experience. Summary of the Invention

[0005] This application provides a headband and headphones that enable multi-angle folding and positioning while making the structure more compact and improving the user experience.

[0006] In a first aspect, embodiments of this application provide a headband, which includes a frame and a folding assembly. The frame is generally arc-shaped and defines a wearing space adapted to the user's head. The folding assembly includes a sliding arm and an earpiece connector. The sliding arm is connected to the frame, and a connecting groove is provided at one end of the sliding arm near the earpiece connector. The earpiece connector has a connecting end, which is located within the connecting groove and rotatably connected to the sliding arm, allowing the earpiece connector to rotate toward or away from the wearing space, thereby switching between a folded state and an unfolded state.

[0007] The inner side of the connecting groove and the connecting end are provided with a first limiting part and a second limiting part, and there are at least two second limiting parts; when the ear shell connector is in the unfolded state, the first limiting part engages with one of the second limiting parts; when the ear shell connector is in the folded state, the first limiting part engages with the other second limiting part for fixation.

[0008] Secondly, embodiments of this application also propose a headset, which includes two earphone units and a headband as described above, wherein one of the earphone units is correspondingly connected to the ear shell connector of the folding assembly.

[0009] In this embodiment, by providing a first limiting part and at least two second limiting parts on the ear shell connector and the sliding arm respectively, the ear shell connector can be hovered relatively stably at least in multiple locations such as the unfolded state and the folded state. This makes the structure of the folding assembly more compact, and the movement and hovering of the ear shell connector relative to the sliding arm more reliable, reducing or avoiding loosening, thereby improving the user experience.

[0017] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0019] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0020] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] Referring to Figure 1, this application discloses a headset 1000. The headset 1000 includes two earphone units 200 and a headband 100. The two earphone units 200 are respectively located at both ends of the headband 100. When worn, the headband 100 spans both sides of the user's head, and the two earphone units 200 are located near the user's ears. Each earphone unit 200 includes an ear shell assembly 201, a driver, and an ear tip assembly 202. The ear shell assembly 201 is connected to the headband 100 and has a sound outlet. The driver is located inside the ear shell assembly 201 and is used to vibrate and generate sound, so that sound waves propagate out from the sound outlet. The ear tip assembly 202 is located on the side of the ear shell assembly 201 with the sound outlet and is used to cover or partially cover the user's ears, so that sound waves propagate towards the user's external auditory canal.

[0023] Obviously, the aforementioned headphones 1000 generally have a large volume. To facilitate storage and folding, some headphones 1000 have a folding function. Therefore, such headphones 1000 have an unfolded state for wearing and a folded state for easy storage. In the folded state, the headphones 1000 occupy less space and are more convenient to carry. Commonly, the headphone unit 200 is folded relative to the headband 100 to make the structure of the headphones 1000 more compact and reduce space occupation. However, in related technologies, the folding angle of the headphone unit 200 is relatively simple, and the connection between the headphone unit 200 and the headband 100 is relatively loose, resulting in a poor user experience.

[0024] Therefore, referring to Figures 1 and 2, another aspect of this application proposes a headband 100, which includes a frame 10 and two sets of folding components 30. The frame 10 is generally arc-shaped, and the two sets of folding components 30 are respectively connected to both ends of the frame 10. It is understood that, taking the headband 100 applied to a headset 1000 as an example, when a user wears the headset 1000 on their head, the headband 100 is in a wearing state. The arc-shaped frame 10 encloses a wearing space 101 located in the middle, and part of the user's head (wearing part) is located within this wearing space 101 to fit the headband 100. The frame 10 is the main structure of the headband 100, providing mounting positions and support for components such as the folding components 30. The arc-shaped frame 10 can fit snugly against the user's head when the headset 1000 is worn, achieving a good wearing effect. The folding assembly 30 is used to mount the headphone unit 200 onto the headband 100, which secures the headphone unit 200 to the user's head.

[0025] The frame 10 and the folding assembly 30 can be made of one or more of the following materials: metal, plastic or leather. This application does not limit this.

[0026] Referring to FIG2, the folding assembly 30 includes a sliding arm 31 and an ear shell connector 33. The sliding arm 31 is connected to the frame 10. The ear shell connector 33 is rotatably connected to the end of the sliding arm 31 away from the frame 10 and is used to connect the headphone unit 200 (ear shell assembly 201) so that the headphone unit 200 can swing relative to the frame 10 with the ear shell connector 33.

[0027] In one embodiment, the end of the frame 10 has an extended mounting cavity (not shown) and an opening communicating with the mounting cavity. A sliding arm 31 is slidably disposed within the mounting cavity and has an end that passes through the opening and is always exposed outside the mounting cavity. The earpiece connector 33 is rotatably connected to the end of the sliding arm 31 exposed outside the mounting cavity. Understandably, when the sliding arm 31 slides within the mounting cavity, it causes the earpiece connector 33 and the headphone unit 200 to move together. To conform to the shape of the frame 10, the mounting cavity may be optionally arc-shaped, and the sliding arm 31 may also be arc-shaped, allowing it to slide smoothly within the mounting cavity. Thus, the sliding arm 31 allows the length of the headband 100 to be variable, improving the usability of the headband 100. In the folded state, most of the sliding arm 31 can be located within the mounting cavity, further reducing the volume of the headphones 1000 when stored.

[0028] Referring to Figures 1 to 3, the ear shell connector 33 is generally rod-shaped, with one end connected to the ear shell assembly 201 and the other end forming a connecting end 331. The connecting end 331 is rotatably connected to the sliding arm 31 and has a rotation axis S. The end of the sliding arm 31 away from the frame 10 is provided with a connecting groove 3131, and the connecting end 331 is located within the connecting groove 3131. Optionally, the headband 100 also includes a pin 35 passing through the sliding arm 31 and the connecting end 331. The sidewall of the connecting groove 3131 and the connecting end 331 are both provided with through holes for the pin 35 to pass through, allowing the connecting end 331 to rotate relative to the sliding arm 31 around the pin 35. When the connecting end 331 rotates, the ear shell connector 33 as a whole can rotate into or away from the wearing space 101. Understandably, when the ear shell connector 33 is away from the wearing space 101, the ear shell connector 33 is in an unfolded state, and the headphone unit 200 is not in the wearing space 101. At this time, the headphones 1000 can be worn and used. When the ear shell connector 33 is in the wearing space 101, it is in a folded state, and the headphone unit 200 is folded and stored in the wearing space 101. This can reduce the storage volume of the headphones 1000 and make it convenient to carry.

[0029] In this embodiment of the application, a first limiting part 50 is provided on the inner side of the connecting groove 3131 and the connecting end 331, and at least two second limiting parts 70 are provided on the other side. Exemplarily, the first limiting part 50 may be provided at the end of the sliding arm 31 and near the connecting groove 3131, and at least two second limiting parts 70 are provided at intervals on the ear shell connector 33 and near the connecting end 331. When the earcup connector 33 is in the unfolded state, the first limiting part 50 engages with one of the second limiting parts 70, making the connection between the earcup connector 33 and the sliding arm 31 more secure. The earcup connector 33 can be more reliably kept relatively fixed to the sliding arm 31, thus maintaining the unfolded state and making it convenient for users to use the headphones 1000. When the earcup connector 33 is in the folded state, the first limiting part 50 engages with the other second limiting part 70, making the earcup connector 33 able to remain in the folded state and the structure more compact, preventing the earcup connector 33 from becoming loose during storage and causing the headphones 1000 to take up more space.

[0030] The first limiting part 50 and the second limiting part 70 can be adapted by means of protrusion and limiting groove, magnetic adsorption, etc., and this application embodiment does not limit this. Of course, the first limiting part 50 and the second limiting part 70 are not limited to being adapted and connected only in the folded state and the unfolded state. Multiple second limiting parts 70 can also be provided so that the ear shell connector 33 can achieve a relatively secure suspension effect at multiple angles.

[0031] Thus, this application provides a first limiting part 50 and at least two second limiting parts 70 on the ear shell connector 33 and the sliding arm 31, so that the ear shell connector 33 can be suspended relatively stably at least in the unfolded state and the folded state, making the structure of the folding assembly 30 more compact, and the movement and suspension of the ear shell connector 33 relative to the sliding arm 31 more reliable, reducing or avoiding loosening, thereby improving the user experience.

[0032] Furthermore, in this embodiment, the connecting end 331 and the connecting groove 3131 are interference-fitted. It should be noted that even with the interference fit, the connecting end 331 retains a certain amount of room to rotate within the connecting groove 3131 under sufficient external force (the force acting on the headphone unit 200 or the earpiece connector 33, causing the earpiece connector 33 to swing). When there is no sufficient external force, this design increases the friction between the connecting end 331 and the connecting groove 3131, making it less likely for the connecting end 331 to rotate relative to the connecting groove 3131. At any position within the swing range, while the connecting end 331 remains in contact with the inner wall of the connecting groove 3131, the headphone 1000 connector can maintain a relatively stable posture relative to the sliding arm 31, reducing the possibility of loosening and resulting in a more compact and robust structure.

[0033] Thus, in this embodiment of the application, by making the connecting end 331 of the ear shell connector 33 and the connecting groove 3131 of the sliding arm 31 interference fit, the connection between the ear shell connector 33 and the sliding arm 31 is relatively tight, reducing the possibility of loosening without affecting the rotation of the connecting end 331 relative to the connecting groove 3131.

[0034] To achieve an interference fit with the connecting end 331, the connecting groove 3131 has opposing side walls that clamp the connecting end 331. These opposing side walls of the connecting groove 3131 are spaced apart and define the opening of the connecting groove 3131, through which the connecting end 331 extends into the connecting groove 3131. The connecting groove 3131 may be integrally defined by the sliding arm 31, or the sliding arm 31 may be a separate structure.

[0035] Referring to Figures 3 to 5, in some embodiments of this application, the sliding arm 31 includes a body 311 and a spring piece 313. The body 311 is slidably connected to the frame 10 and is generally arc-shaped. The body 311 can slide along the aforementioned mounting cavity and has an end that is always exposed outside the mounting cavity. The spring piece 313 is connected to this end.

[0036] In some alternative structural forms, the spring 313 itself defines the aforementioned connecting groove 3131. For example, the spring 313 is roughly U-shaped, with its bottom fixedly connected to the main body 311, and its two sides forming opposing side walls that clamp the connecting section, thus constructing the connecting groove 3131. In this way, the two side walls of the connecting groove 3131 can clamp the connecting end 331 under its own elasticity, realizing an interference fit between the connecting groove 3131 and the connecting end 331.

[0037] Referring to Figure 3, the end of the main body 311 furthest from the frame 10 is provided with a connecting groove 3131. A spring piece 313 is fixed inside the connecting groove 3131 and contacts the connecting end 331. For example, the spring piece 313 can be plate-shaped, with one end fixed to the bottom wall of the connecting groove 3131, while it is spaced apart from one of the side walls of the connecting groove 3131. The spring piece 313 can undergo elastic deformation and, due to its elasticity, abuts against one side of the connecting end 331. Under the action of elasticity, the other side of the connecting end 331 is pressed against the side wall of the connecting groove 3131, thereby achieving an interference fit.

[0038] Alternatively, referring to Figure 4, in one embodiment, the spring piece 313 includes a fixing section 3133 and two limiting sections 3135. The fixing section 3133 is connected to the bottom wall of the connecting groove 3131. For example, both the fixing section 3133 and the bottom wall of the connecting groove 3131 have a hole structure, and the fixing section 3133 is fixed to the bottom wall of the connecting groove 3131 by a screw passing through the fixing section 3133. Of course, the fixing section 3133 can also be connected to the bottom wall of the connecting groove 3131 by snap-fit ​​or embedding, which is not limited here. The two limiting sections 3135 are respectively connected to the opposite sides of the connecting section, so that the spring piece 313 is approximately U-shaped. The edges of the two limiting sections 3135 define the opening of the connecting groove 3131, so that the connecting end 331 can pass through the opening of the connecting groove 3131 and be interference-fitted with the connecting groove 3131. As shown in the figure, both limiting segments 3135 are provided with through holes, and the shaft pin 35 passes through the connecting end 331 and the two limiting segments 3135, so that the connecting end 331 can rotate relative to the spring piece 313 around the shaft pin 35. Optionally, by making the two limiting segments 3135 roughly form an "eight" shape, the distance between the two limiting segments 3135 gradually increases in the direction closer to the fixed segment 3133, and when the connecting end 331 is set in the connecting groove 3131, the two limiting segments 3135 can clamp the connecting end 331, realizing the interference fit between the connecting end 331 and the connecting groove 3131.

[0039] To improve assembly accuracy, in this embodiment, the two limiting segments 3135 are symmetrically arranged. Therefore, when elastic changes occur, the deformation of the two limiting segments 3135 is relatively consistent, ensuring accurate alignment and avoiding asymmetrical deformation that could damage the service life of the spring piece 313. One end of the fixing segment 3133 also extends with a positioning protrusion, and the bottom wall of the connecting groove 3131 is provided with a positioning groove. The positioning protrusion is located in the positioning groove to improve assembly accuracy and efficiency, and to limit the displacement of the fixing segment 3133, further improving the stability of the spring piece 313 and preventing loosening when the connecting end 331 and the connecting groove 3131 are fitted together.

[0040] Optionally, the spring 313 is a metal part, which has high structural strength, can undergo elastic deformation, and has a long service life. The spring 313 can be a one-piece structure, which is easy to process and has good structural integrity.

[0041] In this embodiment, on the one hand, the spring piece 313 can achieve a tighter clamping effect on the connecting end 331, further preventing loosening. On the other hand, the spring piece 313 is set in the connecting groove 3131, and the connecting end 331 extends into the connecting groove 3131 and is adapted to connect with the connecting groove 3131. This not only saves space in the folding component 30 and makes the structure more compact, but also allows the main body 311 to cover and protect the spring piece 313 and the ear shell connector 33, making the appearance simpler and more beautiful.

[0042] Referring to Figure 4, in some embodiments, a first limiting part 50 is provided on at least one side wall of the connecting groove 3131, and at least two second limiting parts 70 are provided on the connecting end 331 and arranged around the rotation axis S. It is understood that the connecting end 331 rotates relative to the sliding arm 31 about the rotation axis S. Of course, it is understood that the first limiting part 50 and the second limiting part 70 are provided on the same side wall of the connecting end 331 to facilitate mutual cooperation.

[0043] Specifically, the first limiting part 50 is disposed on the spring piece 313. When the spring piece 313 has two limiting segments 3135, at least one limiting segment 3135 is provided with the first limiting part 50, and at least two second limiting parts 70 are disposed at intervals on the side of the connecting end 331 facing the spring piece 313 (limiting segment 3135). That is, any limiting segment 3135 may be provided with the first limiting part 50, and the connecting end 331 may be provided with at least two second limiting parts 70 on the side of the limiting segment 3135 provided with the first limiting part 50; or, both limiting segments 3135 may be provided with the first limiting part 50, and correspondingly, both sides of the connecting end 331 may also be provided with at least two second limiting parts 70 to cooperate with the two limiting segments 3135. Thus, while the connecting end 331 and the connecting groove 3131 are in an interference fit, at specific positions, such as when the ear shell connector 33 is in a folded or unfolded state, the connecting end 331 also engages with the spring piece 313 (limiting segment 3135) for limiting adaptation. The clamping force of the interference fit makes the limiting adaptation between the two more compact, thereby further improving the stability and reliability of the ear shell connector 33 when suspended at a specific position, further preventing loosening, and providing a damped feel when the connecting end 331 rotates relative to the connecting groove 3131, improving the user experience. In addition, integrating the interference fit and limiting adaptation into the adaptation connection between the spring piece 313 and the connecting end 331 results in a higher degree of structural integration and a more compact structure. Furthermore, the spring piece 313 (limiting segment 3135) is located on the side of the connecting end 331, rather than on the top of the connecting end 331, thereby saving more space, making the folding assembly 30 more aesthetically pleasing, and occupying less space.

[0044] It is conceivable that if the sliding arm 31 is integrally formed into the first limiting part 50, the material selection and processing must ensure that the sliding arm 31 has sufficient strength, that the first limiting part 50 is easy to form, has a certain degree of elasticity, and has a long service life. This is undoubtedly quite difficult, especially when the structure of the first limiting part 50 is relatively complex. The technical solution of this application integrates the first limiting part 50 onto the spring piece 313, and sets the spring piece 313 and the main body 311 separately. In this way, the spring piece 313 and the main body 311 can be made of different materials and processed and designed specifically to meet the above design requirements, while also facilitating production and improving production efficiency.

[0045] Of course, in other embodiments, the connecting end 331 may be provided with a first limiting part 50, and at least one side wall of the connecting groove 3131 may be provided with at least two second limiting parts 70, which can still achieve the functions and effects described above. The following embodiments are still explained using the example of the connecting groove 3131 having a first limiting part 50 on its side wall and the connecting end 331 having at least two second limiting parts 70.

[0046] Referring to Figures 4 and 5, in one embodiment, the first limiting part 50 is a limiting protrusion, and the second limiting part 70 is a limiting groove. When the first limiting part 50 and the second limiting part 70 are matched, the limiting protrusion is located in the limiting groove; or, when the connecting end 331 rotates, the first limiting part 50 and the second limiting part 70 disengage from the limiting match, and the limiting groove moves relative to the limiting protrusion as the connecting end 331 rotates, until the other limiting groove is matched with the limiting protrusion.

[0047] In this embodiment, the shape of the limiting protrusion can be circular, square, or other shapes. Since the spring piece 313 is small, to increase the range of the limiting protrusion within a limited size, it can extend to the edge of the spring piece 313 (limiting segment 3135), which also facilitates processing. The shape of the limiting groove corresponds to the limiting protrusion, so that when the limiting protrusion is located within the limiting groove, the inner wall of the limiting groove can effectively limit the limiting protrusion, improving the tightness of the connection and preventing loosening. Each second limiting part 70 has at least one limiting groove, and at least two limiting parts have at least two limiting grooves. The rotation axis S of the connecting end 331 coincides with the central axis of the shaft pin 35. The opposite side walls of the connecting groove 3131 are elastic, allowing the distance between the side walls to change elastically. When the connecting end 331 rotates, the limiting groove currently matched with the limiting protrusion rotates relative to the limiting protrusion. The limiting protrusion abuts against the wall surface of the connecting end 331 where the limiting groove is not located. The elastic piece 313 deforms more, resulting in a stronger clamping effect on the connecting end 331. The connecting end 331 rotates with a damped feel without becoming loose, providing a better user experience. At least two limiting grooves are spaced apart around the rotation axis S. Thus, by rotating the connecting end 331, the first limiting part 50 can be matched with the second limiting part 70 at different positions. This embodiment uses a limiting protrusion and limiting groove matching form, which is simple, effective, and easy to manufacture, effectively improving efficiency and reducing processing costs.

[0048] Referring to Figures 4 and 5, in one embodiment of this application, the number of first limiting portions 50 can be two, and the number of second limiting portions 70 can be three, with both first limiting portions 50 and three second limiting portions 70 arranged around the rotation axis S. For ease of explanation, the two first limiting portions 50 are respectively labeled as first limiting protrusions 51 and second limiting protrusions 53, and the three second limiting portions 70 are respectively labeled as first limiting grooves 71, second limiting grooves 73, and third limiting grooves 75. In this embodiment, in the unfolded state, the first limiting protrusions 51 and second limiting protrusions 53 are located within the first limiting grooves 71 and second limiting grooves 73, respectively; in the folded state, the first limiting protrusions 51 are located within the second limiting grooves 73, and the second limiting protrusions 53 are located within the third limiting grooves 75. Thus, the technical solution of this application embodiment can increase the contact area between the connecting end 331 and the connecting groove 3131, improving connection reliability.

[0049] As shown in Figures 2 and 5, in this embodiment, at least two second limiting portions 70 are arranged at intervals around the rotation axis S. Adjacent second limiting portions 70 form an angle α about the rotation axis S, satisfying the relationship: 85°≤α≤100°. If angle α>100°, the earpiece connector 33 may interfere with the headband 100 when folded; if angle α<85°, the earpiece unit 200 cannot be properly stored in the wearing space 101 when folded, resulting in a still large volume of the headphone 1000, making it inconvenient to store. Therefore, to facilitate storage while ensuring that other structures are not interfered with, this application limits the angle to 85°≤α≤100°, where α can be selected from 90°, 95°, 98°, etc.

[0050] The above embodiments illustrate the specific arrangement of the first limiting part 50 and at least two second limiting parts 70 on one side of the connecting end 331. Referring to Figure 4, in some embodiments, the opposite side walls of the connecting groove 3131 are provided with the first limiting part 50, and the opposite sides of the connecting end 331 are provided with at least two second limiting parts 70. It can be understood that the first limiting parts 50 on both sides are symmetrically arranged, and the at least two second limiting parts 70 on the opposite sides of the connecting end 331 are also symmetrically arranged, so that the first limiting parts 50 on both sides can simultaneously adapt to or disengage from the second limiting parts 70. Thus, this embodiment further increases the contact area of ​​the first limiting part 50 and the second limiting part 70. Since the connecting groove 3131 and the connecting end 331 are interference fit, the limiting fit between the first limiting part 50 and the second limiting part 70 on both sides of the connecting end 331 is tighter, the connection strength is higher, it supports the heavier headphone unit 200, and the damping feel is stronger when the connecting end 331 rotates, the structure is more compact, and the user experience is further improved.

[0051] The above explanation is based on the example of the connecting groove 3131 having elasticity to clamp the connecting end 331. In other embodiments, the connecting end 331 can also be elastic and have an interference fit with the connecting groove 3131.
