In related technologies, the earphone case includes an upper shell assembly and a lower shell assembly, which are pivotally connected.

However, ensuring reliable closure of the earphone case and preventing accidental opening remains a pressing technical problem to be solved. Utility Model Content

[0003] This application provides an earphone case, which includes a lower shell assembly, a lower shell magnet, a magnetic sensing element, an upper shell assembly, and an upper shell magnet. The lower shell magnet and the magnetic sensing element are disposed on the lower shell assembly; the upper shell assembly is pivotally connected to the lower shell assembly and switches between an open and closed state relative to the lower shell assembly; the upper shell magnet is disposed on the upper shell assembly; wherein, the upper shell magnet is a single unit, and in the closed state, the upper shell magnet acts simultaneously on both the lower shell magnet and the magnetic sensing element. The upper shell magnet is used to magnetically attract the lower shell magnet, so that the upper shell assembly is in a closed state relative to the lower shell assembly. The upper shell magnet is also used to trigger the magnetic sensing element to generate a detection signal.

[0004] In some embodiments, in the closed state, the earphone case has a thickness direction, along which the projection of the upper shell magnet and the projection of the lower shell magnet at least partially overlap to form a first overlapping region, the area ratio of the first overlapping region to the projection of the lower shell magnet is not less than 0.8; along the thickness direction, the projection of the upper shell magnet and the projection of the magnetic induction element at least partially overlap to form a second overlapping region, the area ratio of the second overlapping region to the projection of the magnetic induction element is not less than 0.8.

[0005] In some embodiments, both the upper shell assembly and the lower shell assembly include a pivot side and an opening / closing side disposed opposite to each other. The pivot side of the upper shell assembly is pivotally connected to the pivot side of the lower shell assembly. The lower shell magnet and the magnetic induction element are disposed near the opening / closing side of the lower shell assembly and are spaced apart from each other along a first direction. The first direction is parallel to the rotation axis between the upper shell assembly and the lower shell assembly. The upper shell magnet is disposed near the opening / closing side of the upper shell assembly. The upper shell magnet is elongated and its length direction is parallel to the first direction.

[0006] In some embodiments, the lower shell assembly includes a lower shell, a lower support, a first circuit board, and a button assembly. The lower support has a flat area and a storage area recessed relative to the flat area. The storage area is used to store the earphone. The flat area includes a first flat area disposed near the opening side of the lower shell assembly. The lower support and the lower shell cooperate to form an accommodating space. The first circuit board is disposed in the accommodating space, and the button assembly is disposed on the first circuit board. At least a portion of the button assembly can be exposed through the first flat area.

[0007] In some embodiments, the magnetic induction element and the lower shell magnet are disposed within the accommodating space, the first circuit board is mounted and fixed below the first flat area, the magnetic induction element is disposed on the first circuit board, and the lower shell magnet is disposed outside the first circuit board and mounted and fixed below the first flat area.

[0008] In some embodiments, the first circuit board is provided with a clearance notch for avoiding the lower housing magnet.

[0009] In some embodiments, the button assembly is located between the lower housing magnet and the magnetic sensing element.

[0010] In some embodiments, in the direction from the magnetic sensing element to the lower housing magnet, the width of the first circuit board and the first flat area gradually widens and then gradually narrows in the second direction, and the button assembly is disposed at the widest position of the first circuit board, with the second direction perpendicular to the rotation axis.

[0011] In some embodiments, the lower housing assembly further includes a second circuit board mounted and fixed below the storage area, the first circuit board being electrically connected to the second circuit board via an electrical connection structure, and the first circuit board being located above the second circuit board along the thickness direction.

[0012] In some embodiments, along the thickness direction, the projection of the first circuit board at least partially overlaps with the projection of the second circuit board.

[0013] In some embodiments, the first circuit board is provided with a mounting position for connecting the first circuit board to a first flat area, and the projection of at least one mounting position along a second direction at least partially overlaps with the clearance notch and the lower shell magnet, and the second direction is perpendicular to the rotation axis.

[0014] In some embodiments, the lower shell assembly includes a lower shell, a lower support, and a magnetic accommodating element. The lower shell and the lower support cooperate to form an accommodating space. The lower shell magnet and a magnetic induction element are disposed within the accommodating space. The lower support has a storage area for storing the earphones. The magnetic accommodating element is disposed within the accommodating space and located below the storage area. The magnetic accommodating element is used to magnetically attract the earphones. In the closed state, the upper shell magnet and the magnetic accommodating element are magnetically attracted to each other.

[0015] In this application, an upper shell magnet is provided on the upper shell assembly and a lower shell magnet is provided on the lower shell assembly. When the upper shell assembly is in a closed state relative to the lower shell assembly, the upper shell magnet and the lower shell magnet are magnetically attracted to each other, ensuring the reliable closure of the headphone case and preventing the headphone case from being accidentally opened.

[0016] Furthermore, the upper shell magnet can also be used to trigger the magnetic induction element set on the lower shell assembly to generate a detection signal, thereby enabling control of the earphones according to the state of the earphone case (open / closed state).

[0017] In other words, in the solution of this application, the upper shell magnet is not only used to attract each other with the lower shell magnet to ensure the stability of the headphone case in the closed state and prevent the headphone case from being accidentally opened in the closed state, but it can also be used to cooperate with the magnetic induction element to detect the state of the headphone case (open state / closed state), realizing the reuse of the upper shell magnet, making the overall structure simpler and helping to reduce costs.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first" and "second" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0030] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0031] like Figure 1 and Figure 2 As shown, this application provides an earphone case 20 for storing earphones 10. In some embodiments, the earphone case 20 can also be used to charge the earphones 10.

[0032] like Figure 2 and Figure 3 As shown, the earphone case 20 includes a lower shell assembly 23, a lower shell magnet 2312, a magnetic induction element 2313, an upper shell assembly 21, and an upper shell magnet 214. The lower shell magnet 2312 and the magnetic induction element 2313 are disposed on the lower shell assembly 23, and the upper shell magnet 214 is disposed on the upper shell assembly 21. The upper shell assembly 21 is pivotally connected to the lower shell assembly 23, and can rotate relative to the lower shell assembly 23. Figure 2 The open state shown and Figure 1 Switching between the closed states shown.

[0033] like Figure 3As shown, the upper shell magnet 214 is a single unit. In the closed state, the upper shell magnet 214 acts simultaneously on the lower shell magnet 2312 and the magnetic induction element 2313.

[0034] On one hand, the upper shell magnet 214 is used to magnetically attract the lower shell magnet 2312, so that the upper shell assembly 21 is in a closed state relative to the lower shell assembly 23, preventing the headphone case 20 from being accidentally opened. Figure 3 As shown, in the closed state, the magnetic poles of the upper shell magnet 214 near the lower shell magnet 2312 are opposite to those of the lower shell magnet 2312 near the upper shell magnet 214, allowing the upper shell magnet 214 and the lower shell magnet 2312 to be magnetically attracted to each other. For example, the lower side of the upper shell magnet 214 can be the N pole, and the upper side of the lower shell magnet 2312 can be the S pole, or the lower side of the upper shell magnet 214 can be the S pole, and the upper side of the lower shell magnet 2312 can be the N pole.

[0035] On the other hand, the upper shell magnet 214 is also used to trigger the magnetic induction element 2313 to generate a detection signal, thereby determining the state (open state / closed state) of the headphone case 20 based on the detection signal, realizing the opening and closing detection, and then controlling the headphone 10 based on the state (open state / closed state) of the headphone case 20.

[0036] In other words, in the solution of this application, the upper shell magnet 214 is not only used to attract each other with the lower shell magnet 2312 to ensure the stability of the headphone case 20 in the closed state and to prevent the headphone case 20 from being accidentally opened in the closed state, but it can also be used to cooperate with the magnetic induction element 2313 to realize the opening and closing detection of the headphone case 20. This realizes the reuse of the upper shell magnet 214, the overall structure is simpler, and it is beneficial to reduce costs.

[0037] It should be noted that, in the description of this application, the upper shell magnet 214 being arranged as a single unit means that the upper shell magnet 214 exists and operates as a single independent individual, rather than multiple magnets combined into an array or other complex structure.

[0038] like Figure 3 and Figure 5 As shown, in some embodiments, in the closed state, along the thickness direction Z2 of the headphone case 20, the projection of the upper shell magnet 214 at least partially overlaps with the projection of the lower shell magnet 2312, and the projection of the upper shell magnet 214 at least partially overlaps with the projection of the magnetic induction element 2313, so as to ensure that in the closed state, the effect of the upper shell magnet 214 on the lower shell magnet 2312 and the magnetic induction element 2313 is sufficiently strong.

[0039] Along the thickness direction Z2 of the headphone case 20, the projections of the upper shell magnet 214 and the lower shell magnet 2312 at least partially overlap, forming a first overlapping area. The larger the first overlapping area, the stronger the magnetic attraction between the upper shell magnet 214 and the lower shell magnet 2312 in the closed state. In some embodiments, in the closed state, the area ratio of the first overlapping area to the projection of the lower shell magnet 2312 along the thickness direction Z2 of the headphone case 20 is not less than 0.8. For example, this ratio can be 0.8, 0.85, 0.9, 0.95, 1.0, etc. This arrangement ensures that the lower shell magnet 2312 is mainly located in the effective area of ​​the magnetic field of the upper shell magnet 214. While ensuring the magnetic attraction between the upper shell magnet 214 and the lower shell magnet 2312, the arrangement of the lower shell magnet 2312 is optimized, which helps to reduce the overall size of the headphone case 20.

[0040] Along the thickness direction Z2 of the headphone case 20, the projection of the upper shell magnet 214 and the projection of the magnetic induction element 2313 at least partially overlap, forming a second overlapping area. The larger the second overlapping area, the higher the accuracy of the opening and closing detection. In some embodiments, in the closed state, along the thickness direction Z2 of the headphone case 20, the area ratio of the second overlapping area to the projection of the magnetic induction element 2313 is not less than 0.8. For example, this ratio can be 0.8, 0.85, 0.9, 0.95, 1.0, etc. With this configuration, the magnetic induction element 2313 is mainly located in the effective magnetic field area of ​​the upper shell magnet 214, ensuring the accuracy of the opening and closing detection while optimizing the position arrangement of the lower shell magnet 2312, which helps to reduce the overall size of the headphone case 20.

[0041] It should be noted that, in the description of this application, "the projection of a certain component along the thickness direction Z2 of the earphone case 20" can refer to the projection of that component onto the first reference plane, wherein the first reference plane is perpendicular to the thickness direction Z2 of the earphone case 20. In the description of this application, "effective area" can refer to the magnetic field region located below the upper shell magnet 214 along the thickness direction Z2 of the earphone case 20 in the closed state, where the magnetic field strength provided by the upper shell magnet 214 is greatest.

[0042] like Figure 3 and Figure 5 As shown, in some embodiments, in the closed state, the projections of the upper shell assembly 21 and the lower shell assembly 23 can completely overlap along the thickness direction Z2 of the earphone case 20. This configuration makes the earphone case 20 square in shape and aesthetically pleasing when closed.

[0043] like Figure 4As shown, in some embodiments, both the upper shell assembly 21 and the lower shell assembly 23 include a pivot side and an opening / closing side disposed opposite to each other. The pivot side 2106 of the upper shell assembly 21 is pivotally connected to the pivot side 2306 of the lower shell assembly 23. For example, when viewed along the thickness direction Z2 of the earphone case 20, the pivot side 2106 of the upper shell assembly 21 and the pivot side 2306 of the lower shell assembly 23 may coincide, and the opening / closing side 2107 of the upper shell assembly 21 and the opening / closing side 2307 of the lower shell assembly 23 may coincide.

[0044] like Figure 4 As shown, in some embodiments, the lower shell magnet 2312 and the magnetic induction element 2313 can be disposed close to the opening / closing side 2307 of the lower shell assembly 23 and spaced apart from each other along a first direction X2. The first direction X2 is parallel to the rotation axis between the upper shell assembly 21 and the lower shell assembly 23. By spaced apart, the mutual interference between the magnetic induction element 2313 and the lower shell magnet 2312 can be reduced. In some embodiments, the upper shell magnet 214 can be disposed close to the opening / closing side 2107 of the upper shell assembly 21. The upper shell magnet 214 is elongated, and its length direction is parallel to the first direction X2, ensuring that the upper shell magnet 214 can simultaneously act on the lower shell magnet 2312 and the magnetic induction element 2313 when closed.

[0045] It should be noted that the term "parallel" as used in this application refers to being approximately parallel. When the angle between the two objects is within 15°, they can be understood as being parallel.

[0046] See Figure 5 and Figure 6 In some embodiments, the lower housing assembly 23 may include a lower housing 230, a lower support 234, a first circuit board 2372, and a button assembly 2372-7. The lower support 234 is provided with a flat area 2347 and a recessed storage area (e.g., [missing information]) relative to the flat area 2347. Figure 6 As shown, the storage area includes a first storage area 2346 and a second storage area 23471, which are used to store the earphones 10. The lower support 234 and the lower shell 230 cooperate to form an accommodating space 23b, and the first circuit board 2372 is disposed within the accommodating space 23b. The button assembly 2372-7 can be disposed on the first circuit board 2372, and at least a portion of the button assembly 2372-7 can be exposed through the flat area 2347 to receive user pressing operation.

[0047] like Figure 5 and Figure 6As shown, in some embodiments, the flat area 2347 includes a first flat area 2340 near the opening side 2307 of the lower housing assembly 23, through which at least a portion of the button assembly 2372-7 can be exposed. In this way, when the user opens the headphone case 20, the button assembly 2372-7 can be positioned close to the user for easy access.

[0048] like Figure 4 and Figure 5 As shown, in some embodiments, the first circuit board 2372, the magnetic induction element 2313, and the lower housing magnet 2312 are all disposed within the accommodating space 23b. Specifically, the first circuit board 2372 can be mounted and fixed below the first flat area 2340. In some embodiments, such as Figure 6 and Figure 8 As shown, the shapes of the first circuit board 2372 and the first flat area 2340 are adapted to each other. The first circuit board 2372 can be arranged in a tapered shape from the opening side 2307 of the lower housing assembly 23 to the pivot side 2306.

[0049] like Figure 5 and Figure 8 As shown, in some embodiments, the magnetic induction element 2313 can be disposed on the first circuit board 2372, and the lower shell magnet 2312 is disposed outside the first circuit board 2372 and assembled and fixed below the first flat area 2340. Due to the recessed design of the storage area relative to the flat area 2347, there is a redundant area below the flat area 2347. By placing components such as the first circuit board 2372, the lower shell magnet 2312, and the magnetic induction element 2313 below the first flat area 2340, the redundant area below the first flat area 2340 can be fully utilized, which is beneficial to improving space utilization and reducing the overall size of the earphone case 20.

[0050] like Figure 8 As shown, in some embodiments, the first circuit board 2372 is provided with a clearance notch 2372-8, which is adapted to the outer contour shape of the lower shell magnet 2312 to avoid the lower shell magnet 2312. As mentioned above, the magnetic induction element 2313 is disposed on the first circuit board 2372, and the lower shell magnet 2312 is disposed outside the first circuit board 2372. By providing the clearance notch 2372-8 on the first circuit board 2372, the distance between the lower shell magnet 2312 and the magnetic induction element 2313 can be reduced, which is beneficial to reducing the length of the upper shell magnet 214 and also makes the overall layout compact, which is beneficial to saving installation space.

[0051] like Figure 8As shown, in some embodiments, the button assembly 2372-7 can be disposed between the lower housing magnet 2312 and the magnetic sensing element 2313. In this way, the lower housing magnet 2312 and the magnetic sensing element 2313 can be disposed on opposite sides of the button assembly 2372-7, which helps to reduce mutual interference between the lower housing magnet 2312 and the magnetic sensing element 2313.

[0052] like Figure 8 As shown, in some embodiments, in the direction from the magnetic induction element 2313 to the lower shell magnet 2312, the width of the first circuit board 2372 and the first flat area 2340 in the second direction Y2 can gradually widen and then gradually narrow. The second direction Y2 is perpendicular to the axis of rotation between the upper shell assembly 21 and the lower shell assembly 23. That is, in the first direction X2, the first circuit board 2372 has its maximum width at its middle position, and the width of the first circuit board 2372 gradually decreases from the middle to both ends.

[0053] like Figure 8 As shown, in some embodiments, the button assembly 2372-7 can be located at the widest position of the first circuit board 2372. By placing the button assembly 2372-7 at the widest position of the first circuit board 2372, and placing the lower housing magnet 2312 and the magnetic induction element 2313 on opposite sides of the widest position, the space on the first circuit board 2372 can be fully utilized, thereby improving space utilization.

[0054] like Figure 5 and Figure 8As shown, in some embodiments, the lower shell assembly 23 further includes a second circuit board 236 mounted and fixed below the storage area. The first circuit board 2372 is electrically connected to the second circuit board 236 via an electrical connection structure (e.g., wires, FPC, or board-to-board connectors). Specifically, along the thickness direction Z2 of the earphone case 20, the first circuit board 2372 is located above the second circuit board 236. The second circuit board 236 can be the main circuit board in the earphone case 20, and the first circuit board 2372 can serve as an adapter board for electrically connecting the magnetic sensing element 2313 and the button assembly 2372-7 to the second circuit board 236. This arrangement utilizes the flat area 2347 and the existing area below the storage area to vertically arrange the first circuit board 2372 and the second circuit board 236. The first circuit board 2372 elevates structures such as the button assembly 2372-7 and the magnetic sensing element 2313, facilitating their operation and optimizing their dimensions. Simultaneously, the layout of the first circuit board 2372 and the second circuit board 236 adapts to the shape of the lower support 234, resulting in a compact overall layout of the earphone case 20, improving space utilization and reducing the overall size of the earphone case 20.

[0055] like Figure 5 As shown, in some embodiments, along the thickness direction Z2 of the headphone case 20, the projection of the first circuit board 2372 and the projection of the second circuit board 236 at least partially overlap. This arrangement, while arranging the first circuit board 2372 and the second circuit board 236 vertically, also allows for the reuse of the space below the first circuit board 2372, resulting in a compact overall layout of the headphone case 20, which improves space utilization and reduces the overall size of the headphone case 20.

[0056] like Figure 8 As shown, in some embodiments, the area of ​​the second circuit board 236 can be larger than that of the first circuit board 2372, so that the second circuit board 236, which serves as the main circuit board, can accommodate more electronic components.

[0057] For example, both the first circuit board 2372 and the second circuit board 236 can be suspended below the lower support 234. For instance, both the first circuit board 2372 and the second circuit board 236 can be fixed below the lower support 234 with screws. This application does not impose any restrictions, and those skilled in the art can choose according to actual needs.

[0058] like Figure 8As shown, in some embodiments, the first circuit board 2372 is provided with a plurality of mounting positions 2372-9 for connecting the first circuit board 2372 to the first flat area 2340. The projection of at least one mounting position 2372-9 along the second direction Y2 at least partially overlaps with the clearance notch 2372-8 and the lower shell magnet 2312, wherein the second direction Y2 is perpendicular to the rotation axis between the upper shell assembly 21 and the lower shell assembly 23.

[0059] For example, the clearance notch 2372-8 can be located at the left end of the first circuit board 2372 in the first direction X2, and the magnetic induction element 2313 can be located at the right end of the first circuit board 2372 in the first direction X2. Considering that the width of the end of the first circuit board 2372 is relatively small and the clearance notch 2372-8 is also provided, it is not suitable to place other electronic components at this position. That is to say, the left end of the first circuit board 2372 is actually a redundant area. By setting the projection of the mounting position 2372-9 along the second direction Y2 to at least partially overlap with the clearance notch 2372-8 and the lower shell magnet 2312, that is, by setting the mounting position 2372-9 on the redundant area of ​​the first circuit board 2372, the space on the first circuit board 2372 can be fully utilized.

[0060] See also Figure 5 and Figure 9 In some embodiments, the lower shell assembly 23 further includes a magnetic suction member 2311, which can be disposed within the receiving space 23b formed by the lower shell 230 and the lower support 234. The magnetic suction member 2311 is disposed within the receiving space 23b and located below the storage area. The magnetic suction member 2311 is used to magnetically attract the earphone 10, so that the earphone 10 can be reliably fixed in the storage area and prevent the earphone 10 from falling out of the storage area.

[0061] In the closed state, the upper shell magnet 214 and the magnetic attractor 2311 can magnetically attract each other, further improving the stability of the headphone case 20 in the closed state and preventing the headphone case 20 from being accidentally opened in the closed state.

[0062] like Figure 2 As shown, in some embodiments, the earphone 10 may include a sound-emitting part 12 and an ear hook 11 connected to the sound-emitting part 12, wherein the ear hook 11 may be generally hook-shaped. Figure 7 As shown, when worn, the ear hook 11 can be wrapped around the outer periphery of the ear to position the sound-emitting part 12 close to the external auditory canal 31.

[0063] like Figure 2 and Figure 6As shown, the shape of the storage area conforms to the outline of the earphone 10. The storage area may include a first storage area 2346 and a second storage area 23471. When the earphone 10 is stored in the storage area in the lower tray 234, the second storage area 23471 can store the sound-emitting part 12, and the first storage area 2346 can store at least part of the ear hook 11. Specifically, the magnetic member 2311 can be disposed below the second storage area 23471 for magnetically attracting the sound-emitting part 12 of the earphone 10.

[0064] See also Figure 2 and Figure 6 In some embodiments, the earphone case 20 can simultaneously accommodate two earphones 10. Correspondingly, there can be two second storage areas 23471 and two first storage areas 2346. Each second storage area 23471 is used to accommodate the sound-emitting part 12 of the corresponding earphone 10, and each first storage area 2346 is used to accommodate at least a portion of the ear hook 11 of the corresponding earphone 10. In some embodiments, the two first storage areas 2346 can be interconnected, or the two second storage areas 23471 can be interconnected, or the first storage area 2346 corresponding to each earphone 10 can be interconnected with the second storage area 23471. This application does not limit this, and those skilled in the art can choose according to actual needs.

[0065] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
