Description

Technical Field

[0001] This utility model relates to the field of wireless headphone technology, and in particular to a headphone case and headphone kit. Background Technology

[0002] The widespread adoption of wireless earphones has driven the continuous evolution of their charging case design. Sliding lids, with their intuitive opening and closing, ease of operation, and minimalist aesthetics, have become a mainstream design. However, most existing sliding earphone cases use linear guides, meaning the sliding paths of the upper and lower lids are nearly parallel. This results in a consistently small or constant gap between the upper and lower lids during opening and closing. With frequent sliding operations, especially when the user applies slight force, there are minor assembly tolerances, thermal expansion and contraction of components, or accumulated wear and tear, the sliding contact surfaces of the upper and lower lids are prone to hard friction or even direct scratches. This not only creates unsightly scratches, burrs, or paint chips at the contact edges, severely impacting the product's appearance and user experience, but also, over time, increases sliding resistance, leading to stiff opening and closing, abnormal noises, and even accelerated structural aging and failure. Utility Model Content

[0003] To address the technical problem that existing sliding headphone cases are prone to scratching the device body, this utility model provides a headphone case and headphone kit.

[0004] The present invention provides an earphone case, comprising a slidingly connected upper cover assembly and a lower cover assembly. The upper cover assembly has a main sliding groove and a secondary sliding groove formed on the side near the lower cover assembly. The main sliding groove and the secondary sliding groove are arranged along the sliding direction of the upper cover assembly and the lower cover assembly. One end of the lower cover assembly has a main slider and a secondary slider corresponding to the main sliding groove and the secondary sliding groove, respectively. The main slider is embedded in the main sliding groove, and the main slider cooperates with the main sliding groove to allow the upper cover assembly and the lower cover assembly to be slidably connected. The height of the secondary slider is greater than the maximum depth of the secondary sliding groove, and the secondary slider cooperates with the secondary sliding groove to allow a gap between the upper cover assembly and the lower cover assembly.

[0005] Preferably, the bottom of the secondary slide groove is an inclined surface, and when the upper cover assembly covers the lower cover assembly, the groove depth of the secondary slide groove near the secondary slider is less than the groove depth of the end away from the secondary slider.

[0006] Preferably, the secondary slide groove is arranged parallel to the main slide groove.

[0007] Preferably, the bottom of the main slide groove is provided with a through hole along its length, the secondary slide groove is provided on the side of the through hole, the main slide block passes through the through hole, and the main slide block includes a connecting part and a limiting part connected together. The limiting part is located on the side of the through hole away from the lower cover assembly, and the width of the limiting part is greater than the width of the through hole.

[0008] Preferably, a buffer layer is provided on the outer periphery of the connecting part, and a first gap exists between the buffer layer and the inner wall of the through hole.

[0009] Preferably, the upper cover assembly includes an upper cover body and an upper inner liner that are interlocked with each other. The main sliding groove is located on the side of the upper inner liner away from the lower cover assembly, and the secondary sliding groove is located on the side of the upper inner liner closer to the lower cover assembly. The upper cover body is provided with a first limiting structure on the side close to the upper inner liner. The first limiting structure is arranged along the length direction of the main sliding groove, and the limiting part is provided with a second limiting structure that cooperates with the first limiting structure. When the first limiting structure and the second limiting structure cooperate, there is a second gap between the end of the second limiting structure close to the upper cover body and the first limiting structure.

[0010] Preferably, the lower cover assembly includes a lower cover body and a lower liner that are interlocked. The lower liner has a positioning groove on the side away from the lower cover body. The main slider is partially housed in the positioning groove. The main slider has a fixing hole at the end near the positioning groove. The positioning groove and the fixing hole have a connecting hole at the corresponding positions. A fixing member is provided on the side of the connecting hole away from the main slider. The fixing member passes through the connecting hole and cooperates with the fixing hole to fix the main slider onto the positioning groove.

[0011] Preferably, the secondary slider is located on the side of the lower liner near the upper cover assembly, and the secondary slider is a raised structure that matches the secondary slide groove.

[0012] Preferably, the lower cover assembly is provided with a first magnetic element, which is disposed near the main slider; the upper cover assembly is provided with a second magnetic element and a third magnetic element, which are disposed at opposite ends of the main slide groove along its length. When the earphone case is in the closed state, the first magnetic element and the second magnetic element are magnetically attracted; when the earphone case is in the open state, the first magnetic element and the third magnetic element are magnetically attracted.

[0013] To solve the above-mentioned technical problems, this utility model provides another technical solution as follows: an earphone kit, including an earphone case as described in any of the above claims and a pair of earphones, wherein the lower cover assembly is provided with a storage slot, and the earphones are housed in the earphone case through the storage slot.

[0014] Compared with the prior art, the earphone case and earphone kit provided by this utility model have the following advantages:

[0015] 1. This utility model provides an earphone case. Through the sliding connection of the upper cover assembly and the lower cover assembly, as well as the cooperation of the main and secondary sliding grooves and the slider, the flexibility and stability of the opening and closing of the earphone case are achieved. The main slider is embedded in the main sliding groove to ensure basic sliding connection. The height of the secondary slider is greater than the maximum depth of the secondary sliding groove. Thus, when the secondary slider and the secondary sliding groove abut against each other, the upper cover assembly is lifted to a gap with the lower cover assembly. That is, when the upper cover assembly slides relative to the lower cover assembly, there is a gap between them to make the sliding smooth. At the same time, this design can effectively prevent the upper cover assembly from scratching the body during the sliding process, protect the appearance and structural integrity of the earphone case, and improve the service life and reliability of the product.

[0016] 2. The earphone case provided in this embodiment of the utility model has a sloping bottom for the secondary sliding groove. When the upper cover assembly closes the lower cover assembly, the groove depth is smaller at the end of the secondary sliding groove closer to the secondary slider and larger at the end farther from the secondary slider. This structure causes the engagement depth between the secondary slider and the secondary sliding groove to gradually decrease during the opening process, that is, the upper cover assembly moves upward, thereby increasing the gap between it and the lower cover assembly. Secondly, when the cover is closed, the secondary slider first contacts the shallow groove area, and when the cover is opened, it slides out from the deep groove end, forming a gradual separation. This structure reduces the contact pressure at the initial stage of opening the cover, avoids instantaneous hard friction, further reduces the risk of scratching, and improves the smoothness of the sliding feel.

[0017] 3. The earphone case provided in this utility model embodiment has a secondary slide groove arranged parallel to the main slide groove, which ensures that the main and secondary sliders move in their respective slide grooves in a stable and coordinated manner during the sliding process of the top cover assembly. This avoids problems such as jamming and offset that may be caused by inconsistent slide groove directions, improves the stability and reliability of the sliding cover operation, and allows users to open and close the earphone case more smoothly during use.

[0018] 4. In the headphone case provided in this embodiment of the utility model, the main slider is inserted into the through hole, and the limiting part is located on the side of the through hole away from the lower cover assembly and its width is greater than the width of the through hole. This design allows the limiting part to be locked on the outside of the through hole to form an axial lock, which can effectively prevent the main slider from coming out of the through hole, and play the role of fixing the main slider, ensuring the stability of the connection between the upper cover assembly and the lower cover assembly, preventing the upper cover assembly from coming off, and improving the durability of the headphone case.

[0019] 5. The earphone case provided in this embodiment of the present invention has a first gap between the buffer layer on the outer periphery of the connecting part and the inner wall of the through hole. The buffer layer can reduce the friction and collision generated during the sliding process to a certain extent, reduce noise, and play a role in buffering and shock absorption. The existence of the first gap provides deformation space for the buffer layer, making the buffering effect better, thereby extending the service life of the earphone case, improving the user's comfort, and also helping to improve the smoothness and comfort of the sliding operation.

[0020] 6. The earphone case provided in this embodiment of the utility model has an upper cover and an upper inner liner that are interlocked and fixed together. The main slide groove is provided on the upper inner liner. The cooperation between the first limiting structure and the second limiting structure further enhances the stability of the internal structure of the upper cover assembly, prevents relative displacement between the upper cover and the limiting part, and ensures the positional accuracy and stability of the main slide groove. This ensures a good fit between the main slider and the main slide groove, and improves the accuracy and reliability of the sliding operation. Secondly, the cooperation between the first limiting structure and the second limiting structure restricts the rotational freedom of the main slider, avoiding uneven wear caused by torsion during sliding. At the same time, it disperses stress to the entire upper cover, improving the deformation resistance of the main slide groove.

[0021] 7. The headphone case provided in this embodiment of the present invention features a main slider portion embedded in a positioning groove, which provides initial positioning for the assembly of the main slider, simplifies the assembly process, and improves assembly efficiency. The main slider is fixedly connected to the lower inner liner through fixing holes, connecting holes, and fasteners. This structure provides strong axial constraint force, thereby firmly installing the main slider on the lower cover assembly, ensuring that the main slider will not loosen or fall off during sliding, improving the stability of the main slider and the main slide groove, enhancing the structural strength and reliability of the headphone case, and also facilitating the quick installation and disassembly of the main slider, which is beneficial to the production, manufacturing, and maintenance of the headphone case.

[0022] 8. The earphone case provided in this utility model embodiment has a secondary slider as a raised structure located on the side of the lower inner lining near the upper cover assembly. The raised design makes the cooperation between the secondary slider and the secondary slide groove more tight and precise. The raised structure can better transmit force and guide the direction of movement when sliding, which enhances the stability and reliability of the sliding connection between the upper cover assembly and the lower cover assembly. At the same time, it facilitates production and assembly and reduces manufacturing costs.

[0023] 9. The earphone case provided in this embodiment of the utility model, by setting a first magnetic component on the lower cover assembly and setting a second and third magnetic component on the upper cover assembly, utilizes magnetic attraction to achieve automatic adsorption and positioning of the earphone case in the closed and open states, improving the convenience of use and user experience of the earphone case. At the same time, the setting of the magnetic component can also increase the tightness after the lid is closed, preventing the earphone case from being accidentally opened during carrying, protecting the safety of the earphones, and enhancing the user experience.

[0024] 10. This utility model embodiment also provides an earphone kit, which includes an earphone case as described in any of the preceding claims and a pair of earphones. The lower cover assembly is provided with a storage slot, through which the earphones are housed in the earphone case.

[0025] Understandably, the storage slot on the lower cover assembly provides reasonable storage space for the earphones, facilitating their storage and protection, and preventing damage or loss during transport. Furthermore, the matching design of the earphone case and earphones better suits user habits, enhancing the overall practicality and market competitiveness of the product. The earphone kit provided in this embodiment has the same beneficial effects as the earphone case described in any of the preceding embodiments, and will not be repeated here.

[0041] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0046] Please see Figure 1 and Figure 2 This utility model provides an earphone case 10, including an upper cover assembly 1 and a lower cover assembly 2 that are slidably connected. The upper cover assembly 1 has a main slide groove 13 and a secondary slide groove 14 formed on the side near the lower cover assembly 2. The main slide groove 13 and the secondary slide groove 14 are arranged along the sliding direction of the upper cover assembly 1 and the lower cover assembly 2. One end of the lower cover assembly 2 is provided with a main slider 23 and a secondary slider 24 that cooperate with the main slide groove 13 and the secondary slide groove 14. The main slider 23 is embedded in the main slide groove 13, and the main slider 23 cooperates with the main slide groove 13 to make the upper cover assembly 1 and the lower cover assembly 2 slidably connected. The height of the secondary slider 24 is greater than the maximum depth of the secondary slide groove 14, and the secondary slider 24 cooperates with the secondary slide groove 14 to make the upper cover assembly 1 and the lower cover assembly 2 have a gap.

[0047] Understandably, this utility model embodiment provides an earphone case 10, which achieves flexibility and stability in opening and closing through the sliding connection of the upper cover assembly 1 and the lower cover assembly 2, as well as the cooperation of the main and auxiliary sliding grooves 14 and the slider. The main slider 23 is embedded in the main sliding groove 13 to ensure basic sliding connection. The height of the auxiliary slider 24 is greater than the maximum depth of the auxiliary sliding groove 14, so that when the auxiliary slider 24 and the auxiliary sliding groove 14 abut against each other, the upper cover assembly 1 is lifted to a gap with the lower cover assembly 2. That is, when the upper cover assembly 1 slides relative to the lower cover assembly 2, there is a gap between them to make the sliding smooth. At the same time, this design can effectively prevent the upper cover assembly 1 from scratching the body during the sliding process, protect the appearance and structural integrity of the earphone case 10, and improve the service life and reliability of the product.

[0048] As a feasible implementation method, when the upper cover assembly 1 and the lower cover assembly 2 are closed, there is a small gap between them, and as the opening stroke continues, the gap between them gradually increases, so that the upper cover assembly 1 has a gap with the lower cover assembly 2 throughout the sliding process, preventing it from scratching the surface of the earphone case 10 when sliding.

[0049] In a specific embodiment, when the lid is closed, the distance between the upper cover assembly 1 and the lower cover assembly 2 is 0.05mm; when the lid is halfway open, the distance between them is 0.182mm; and when the lid is fully open, the distance between them is 0.304mm. It should be understood that the distance between the upper cover assembly 1 and the lower cover assembly 2 can be set according to specific product requirements.

[0050] Please see Figure 3 Furthermore, the secondary slide 14 is arranged in parallel with the main slide 13.

[0051] As a feasible implementation method, a set of auxiliary slide grooves 14 are provided on both sides of the main slide groove 13 along its length and are arranged in parallel with it to ensure that the sliding trajectories of the main slide block 23 and the auxiliary slide block 24 are consistent during the sliding process of the upper cover assembly 1 relative to the lower cover assembly 2.

[0052] Optionally, the number of secondary sliding grooves 14 provided on the upper cover assembly 1 can be one set, three sets, or other numbers, which can be set according to the actual product requirements, and no further restrictions are imposed here.

[0053] Understandably, the secondary slide 14 is set parallel to the main slide 13, which ensures that the movement trajectory of the main and secondary sliders in their respective slides is stable and coordinated during the sliding process of the upper cover assembly 1. This avoids problems such as jamming and offset that may be caused by inconsistent slide directions, improves the stability and reliability of the sliding cover operation, and allows users to open and close the headphone case 10 more smoothly during use.

[0054] Please combine Figures 4-6 Furthermore, the bottom of the secondary slide groove 14 is an inclined surface. When the upper cover assembly 1 covers the lower cover assembly 2, the groove depth of the secondary slide groove 14 near the secondary slider 24 is less than the groove depth of the end away from the secondary slider 24.

[0055] It should be noted that, Figure 4 and Figure 5These are enlarged views of the opposite ends of the secondary slide groove 14 at a proportional scale. As can be seen from the figures, the groove depths of the opposite ends of the secondary slide groove 14 are inconsistent. Therefore, the engagement depths of the secondary slider 24 and the secondary slide groove 14 are different when the earphone case 10 is in the closed or open state. This results in different distances between the outer edge of the secondary slide groove 14 and the upper surface of the lower inner liner 22. It should be understood that when the upper cover assembly 1 slides in the opening direction, that is, when the secondary slider 24 moves from the deeper end of the secondary slide groove 14 to the shallower end, the distance between the upper cover assembly 1 and the lower cover assembly 2 gradually increases.

[0056] Understandably, this structure causes the engagement depth between the secondary slider 24 and the secondary slide groove 14 to gradually decrease during the opening process. That is, the upper cover assembly 1 gradually moves upward under the action of the secondary slider 24, thereby increasing the gap between it and the lower cover assembly 2. Secondly, when the cover is closed, the secondary slider 24 first contacts the shallow groove area, and when the cover is opened, it slides out from the deep groove end, forming a gradual separation. This structure reduces the contact pressure at the beginning of opening the cover, avoids instantaneous hard friction, further reduces the risk of scratching, and at the same time improves the smoothness of the sliding feel.

[0057] Furthermore, please combine Figure 2 and Figure 7 , Figure 8 The bottom of the main slide groove 13 is provided with a through hole 131 along its length direction. The secondary slide groove 14 is provided on the side of the through hole 131. The main slide block 23 passes through the through hole 131. The main slide block 23 includes a connecting part 231 and a limiting part 232 connected together. The limiting part 232 is located on the side of the through hole 131 away from the lower cover assembly 2. The width of the limiting part 232 is greater than the width of the through hole 131.

[0058] Understandably, this design allows the limiting part 232 to lock axially outside the through hole 131, effectively preventing the main slider 23 from coming out of the through hole 131. This serves to fix the main slider 23, ensuring the stability of the connection between the upper cover assembly 1 and the lower cover assembly 2, preventing the upper cover assembly 1 from coming off, and improving the durability of the earphone case 10.

[0059] As a feasible implementation, the main slider 23 is specifically T-shaped, with one end of its connecting part 231 connected to the lower cover assembly 2 and the other end connected to the limiting part 232. The connecting part 231 is housed in the through hole 131. The lower cover assembly 2 and the limiting part 232 are located on opposite sides of the through hole 131, and the width of the limiting part 232 is greater than the width of the through hole 131, thereby limiting the upper cover assembly 1 to be located above the upper cover assembly 1 and achieving a stable sliding connection with the main slider 23.

[0060] As another feasible implementation, the width of the connecting part 231 is smaller than the width of the through hole 131, that is, there is a sliding gap between the connecting part 231 and the through hole 131, so as to ensure that the main slider 23 and the main slide groove 13 slide smoothly.

[0061] Furthermore, a buffer layer 233 is provided on the outer periphery of the connecting part 231, and a first gap 234 exists between the buffer layer 233 and the inner wall of the through hole 131.

[0062] It should be noted that the thickness of the buffer layer 233 is less than the sliding gap between the connecting part 231 and the through hole 131. Therefore, even if the connecting part 231 is fitted with a buffer layer 233, there is a first gap 234 between the buffer layer 233 and the through hole 131 to ensure that the connecting part 231 and the through hole 131 can slide smoothly.

[0063] Understandably, the buffer layer 233 can reduce friction and collision during sliding to a certain extent, reduce noise, and play a role in buffering and shock absorption. The presence of the first gap 234 provides deformation space for the buffer layer 233, making the buffering effect better, thereby extending the service life of the earphone case 10, improving the user's comfort, and also helping to improve the smoothness and comfort of sliding operation.

[0064] Optionally, the materials used to prepare the buffer layer 233 include, but are not limited to, one or more of natural rubber, polyethylene foam, silicone rubber, and elastic sponge.

[0065] Furthermore, the upper cover assembly 1 includes an upper cover body 11 and an upper inner liner 12 that are interlocked with each other. A main slide groove 13 is located on the side of the upper inner liner 12 away from the lower cover assembly 2, and a secondary slide groove 14 is located on the side of the upper inner liner 12 close to the lower cover assembly 2. A first limiting structure 111 is provided on the side of the upper cover body 11 close to the upper inner liner 12. The first limiting structure 111 is arranged along the length direction of the main slide groove 13. A second limiting structure 2321 that cooperates with the first limiting structure 111 is provided on the limiting part 232. When the first limiting structure 111 and the second limiting structure 2321 cooperate, a second gap 112 exists between the end of the second limiting structure 2321 close to the upper cover body 11 and the first limiting structure 111.

[0066] Understandably, the cooperation between the first limiting structure 111 and the second limiting structure 2321 further enhances the stability of the internal structure of the upper cover assembly 1, prevents relative displacement between the upper cover body 11 and the limiting part 232, ensures the positional accuracy and stability of the main slide groove 13, thereby ensuring a good fit between the main slider 23 and the main slide groove 13, and improving the accuracy and reliability of the sliding cover operation; secondly, the cooperation between the first limiting structure 111 and the second limiting structure 2321 restricts the rotational freedom of the main slider 23, avoiding uneven wear caused by torsion during sliding; at the same time, it disperses stress to the entire upper cover body 11, improving the deformation resistance of the main slide groove 13.

[0067] Optionally, the first limiting structure 111 and the second limiting structure 2321 are either protrusions or grooves that mate with the protrusions.

[0068] As a feasible implementation, the first limiting structure 111 is a protrusion, and the second limiting structure 2321 is a groove. The upper surface of the limiting part 232, that is, the side near the upper cover 11, is provided with two grooves along the length direction of the through hole 131. The lower cover assembly 2 is provided with a protrusion that can slide and cooperate with the groove on the side near the limiting part 232. The length of the protrusion, that is, the first limiting structure 111, is the same as the length of the through hole 131, so that the first limiting structure 111 and the second limiting structure 2321 are in a cooperative state during the sliding process of the lower cover assembly 2.

[0069] Specifically, when the first limiting structure 111 and the second limiting structure 2321 are engaged, there is a second gap 112 between the bottom of the second limiting structure 2321 and the first limiting structure 111, that is, when the cover is opened and closed, the upper cover 11 is allowed to move slightly up and down relative to the main slider 23.

[0070] It should be noted that when the upper cover assembly 1 is opened and slids, the secondary slider 24 slides against the inclined secondary slide groove 14 to gradually lift the upper cover assembly 1. It should be understood that when the upper cover assembly 1 is lifted, its whole body is inclined relative to the lower cover assembly 2. The second gap 112 provides room for the tilt of the upper cover body 11, so that the upper cover assembly 1 can be lifted smoothly during the sliding process.

[0071] Furthermore, please refer to the following: Figure 9 The lower cover assembly 2 includes a lower cover body 21 and a lower inner liner 22 that are interlocked. The lower inner liner 22 has a positioning groove 223 on the side away from the lower cover body 21. The main slider 23 is partially housed in the positioning groove 223. The main slider 23 has a fixing hole 235 at the end near the positioning groove 223. The positioning groove 223 has a connecting hole 221 at the corresponding position of the fixing hole 235. A fixing member 236 is provided on the side of the connecting hole 221 away from the main slider 23. The fixing member 236 passes through the connecting hole 221 and cooperates with the fixing hole 235 to fix the main slider 23 onto the positioning groove 223.

[0072] Understandably, the structural design of the main slider 23 partially embedded in the positioning groove 223 provides initial positioning for the assembly of the main slider 23, simplifies the assembly process, and improves assembly efficiency. Secondly, the main slider 23 is fixedly connected to the lower inner liner 22 through the fixing hole 235, the connecting hole 221, and the fastener 236. This structure can provide strong axial constraint force, thereby firmly installing the main slider 23 on the lower cover assembly 2, ensuring that the main slider 23 will not loosen or fall off during the sliding process, improving the stability of the cooperation between the main slider 23 and the main slide groove 13, enhancing the structural strength and reliability of the headphone box 10, and also facilitating the quick installation and disassembly of the main slider 23, which is beneficial to the production, manufacturing, and maintenance of the headphone box 10.

[0073] As a feasible implementation method, the fixing hole 235 is a threaded hole, and the fixing member 236 is a bolt or screw. The fixing member 236 is threadedly engaged with the fixing hole 235 to detachably fix the main slider 23 to the lower inner liner 22, ensuring the stability of the connection. The bolt or screw can achieve a quick fixing operation and improve production efficiency.

[0074] Furthermore, the secondary slider 24 is located on the side of the lower inner liner 22 near the upper cover assembly 1, and the secondary slider 24 is a raised structure that matches the secondary slide groove 14.

[0075] Understandably, the raised design makes the cooperation between the secondary slider 24 and the secondary slide groove 14 more tight and precise. The raised structure can better transmit force and guide the direction of movement when sliding, which enhances the stability and reliability of the sliding connection between the upper cover assembly 1 and the lower cover assembly 2, while facilitating production and assembly and reducing manufacturing costs.

[0076] In one embodiment, the secondary slider 24 is integrally formed on the lower inner liner 22.

[0077] Specifically, the secondary slider 24 is an arc-shaped protrusion, and a solid lubricating coating is applied to the secondary slider 24 to reduce its coefficient of friction with the secondary slide groove 14.

[0078] Furthermore, please combine Figure 2 and Figure 7 The lower cover assembly 2 is provided with a first magnetic element 25, which is located near the main slider 23. The upper cover assembly 1 is provided with a second magnetic element 15 and a third magnetic element 16, which are located at both ends of the main slide groove 13 along its length. When the earphone case 10 is in the closed state, the first magnetic element 25 and the second magnetic element 15 are magnetically attracted. When the earphone case 10 is in the open state, the first magnetic element 25 and the third magnetic element 16 are magnetically attracted.

[0079] Understandably, by setting a first magnetic element 25 on the lower cover assembly 2 and setting a second magnetic element 15 and a third magnetic element 16 on the upper cover assembly 1, the earphone case 10 is automatically attracted and positioned in the closed and open states by using magnetic attraction, which improves the ease of use and user experience of the earphone case 10. At the same time, the setting of magnetic elements can also increase the tightness after the lid is closed, prevent the earphone case 10 from being accidentally opened during carrying, protect the safety of the earphone 20, and enhance the user experience.

[0080] It should be noted that the lower inner liner 22 has a first positioning hole 222 for receiving the first magnetic component 25 on the side opposite to the upper cover assembly 1, and the upper inner liner 12 has a second positioning hole 121 and a third positioning hole 122 for receiving the second magnetic component 15 and the third magnetic component 16 respectively at opposite ends on the side opposite to the lower cover assembly 2. The design of the positioning holes allows the position of the magnetic components to be determined in advance, so that the assembly workers do not need to spend extra time adjusting the position of the magnetic components, thereby improving assembly efficiency and assembly accuracy.

[0081] Specifically, the shape of the positioning hole matches the shape of the corresponding magnetic component and is fixedly set inside the positioning hole, so that the magnetic component will not shift during assembly or use, ensuring the accuracy and reliability of the automatic adsorption of the headphone case 10 in both open and closed states.

[0082] In one implementation, the first magnetic element 25, the second magnetic element 15, and the third magnetic element 16 are all magnets. The first magnetic element 25 can be magnetically attracted to the first and second magnetic elements 15. Specifically, the main slider 23 is provided with a circular magnet on each of its opposite sides, namely the first magnetic element 25. The upper cover assembly 1 is provided with two circular magnets corresponding to the first magnetic element 25 at both ends of its sliding direction, namely the second magnetic element 15 and the third magnetic element 16. When the upper cover assembly 1 slides to close with the lower cover assembly 2, the first magnetic element 25 and the second magnetic element 15 are magnetically attracted to provide a closing force. When the upper cover assembly 1 slides to be misaligned with the lower cover assembly 2, that is, when the cover is opened, the first magnetic element 25 and the third magnetic element 16 are magnetically attracted to prevent the upper cover assembly 1 from detaching from the lower cover assembly 2, thereby enhancing the portability and safety of use.

[0083] Optionally, the first magnetic element 25, the second magnetic element 15, and the third magnetic element 16 can be triangular, square, elliptical, etc.

[0084] In another implementation, the first magnetic element 25 is a magnet, and the second magnetic element 15 and the third magnetic element 16 are ferromagnetic metals such as iron, cobalt, nickel or their alloys. Depending on the actual product requirements, the first magnetic element 25 can also be made of a ferromagnetic metal, and the second magnetic element 15 and the third magnetic element 16 can be made of magnets, as long as the first magnetic element 25 can be magnetically attracted to the second magnetic element 15 and the third magnetic element 16 respectively.

[0085] Please refer to the following: Figure 9 This utility model embodiment also provides an earphone kit, including an earphone case 10 as described in any of the above claims and a pair of earphones. The lower cover assembly 2 is provided with a storage slot 26, through which the earphones are housed in the earphone case 10.

[0086] Understandably, the storage slot 26 on the lower cover assembly 2 provides a reasonable storage space for the headphones, facilitating their storage and protection, and preventing damage or loss during transport. At the same time, the matching design of the headphone case 10 and the headphones better suits the user's habits, enhancing the overall practicality and market competitiveness of the product. The headphone kit provided in this embodiment has the same beneficial effects as the headphone case 10 described in any of the above embodiments, and will not be repeated here.

[0087] As a feasible implementation, the lower inner liner 22 is provided with two storage slots 26. The shape of the storage slots 26 matches the shape of the headphones. When the headphones are placed in the storage slots 26, the upper cover assembly 1 does not interfere with the headphones, thereby ensuring that the headphone box 10 can be opened or closed smoothly.

[0088] As another feasible implementation, a receiving space 27 is defined between the lower inner liner 22 and the lower cover 21. The receiving space 27 houses the power supply component 3. The bottom of the storage slot 26 is provided with a first charging contact. The power supply component 3 is electrically connected to the first charging contact. The earphone is provided with a second charging contact at the position corresponding to the first charging contact. When the earphone is stored in the storage slot 26, the first charging contact is electrically connected to the second charging contact, thereby charging the earphone in the storage slot 26.

[0089] In some embodiments, the power supply component 3 includes a circuit board 33, which is electrically connected to a first charging contact. The circuit board 33 is provided with a charging port 32, which can be electrically connected to an external power source, thereby introducing the power of the external power source into the first charging contact to charge the earphones in the storage slot 26.

[0090] In other embodiments, the power supply component 3 further includes a battery 31, which is electrically connected to the circuit board 33 and the first charging contact, thereby transferring electrical energy from the battery 31 to the earphone to charge it.
