Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of earphones, and in particular to an earphone box and an earphone assembly. BACKGROUND

[0002] With the continuous progress of science and technology, more and more electronic products such as smart phones, smart wearable devices (such as smart watches, bracelets, etc.), wireless earphones, etc. have entered people's lives and have become one of the necessities of people's daily life. In order to improve the appearance of the shell of the electronic device, the shell of the electronic device is usually decorated to give the shell a unique appearance design.

[0003] For example, taking an earphone box as an example, it can include a base shell and a decorative sheet. The inside of the base shell can enclose a receiving cavity for accommodating earphones, a main control board and other structural members. The decorative sheet can be attached to the outer surface of the base shell to give the earphone box a unique color, pattern, texture and texture appearance design. The decorative sheet usually wraps the edge of the base shell, so that part of the decorative sheet is located in the receiving cavity of the base shell and is attached to the inner surface of the base shell, occupying the space of the receiving cavity inside the base shell, which is not conducive to the layout design of the structural members in the receiving cavity and is not conducive to the miniaturization design of the earphone box. Content of the utility model

[0004] Embodiments of the present application provide an earphone box and an earphone assembly. The edge of the decorative piece of the earphone box does not need to form a wrapping structure, avoiding occupying the space of the receiving cavity inside the shell, facilitating the layout of other structural members in the shell, and meeting the miniaturization design requirements of the earphone box.

[0005] A first aspect of embodiments of the present application provides an earphone box, including a shell, an adhesive layer and a decorative piece. One end of the shell has an opening, and the inside of the shell encloses a receiving cavity in communication with the opening. The outer surface of the shell has a first edge structure. The first edge structure is located at the edge of the end of the shell having the opening, and the first edge structure is arranged around the opening. The first edge structure protrudes from the outer surface. The first end of the first edge structure can be fixed to the outer surface of the shell, and the second end of the first edge structure can protrude and extend a certain height away from the outer surface of the shell. The first edge structure can be a protruding structure on the outer surface of the shell.

[0006] The decorative piece is attached to the outer surface of the shell through the adhesive layer, so that the decorative piece can be fixed to the outer surface of the shell, realizing the attachment assembly between the decorative piece and the shell.

[0007] The decorative piece is located on one side of the first convex edge structure, and the two sides of the decorative piece opposite to the first convex edge structure are attached, for example, along the height direction of the earphone box, the decorative piece can be located on one side of the first convex edge structure. Along the height direction, the side of the decorative piece facing the first convex edge structure and the side of the first convex edge structure facing the decorative piece are attached and contacted, so that the decorative piece is spliced with the first convex edge structure. The first convex edge structure provided with the protrusion can hide and shield the edge of the decorative piece (such as the part attached to the first convex edge structure), reduce or avoid the problem of wear caused by the exposure of the edge of the decorative piece, and also can avoid the phenomenon of edge warping caused by the exposure of the edge of the decorative piece, so as to ensure the high assembly firmness between the decorative piece and the shell.

[0008] In this way, the edge of the decorative piece does not need to form a wrapping structure, the decorative piece is attached to the outer surface of the shell and does not extend into the accommodation cavity of the shell, which can avoid occupying the space of the accommodation cavity inside the shell, especially in the example that the material of the decorative piece is a relatively thick leather sheet, which can significantly reduce the space occupied by the decorative piece inside the shell, facilitate the layout design of other structural parts in the accommodation cavity, and facilitate the miniaturization design of the shell and the earphone box. Moreover, the edge part of the decorative piece does not need to be bent into the accommodation cavity to form a wrapping structure, which can reduce or avoid the wrinkle problem caused by the bending of the edge of the decorative piece, facilitate the improvement of the flatness of the decorative piece on the outer surface of the shell, and improve the appearance of the earphone box.

[0009] In addition, the first convex edge structure provided with the protrusion also has a positioning effect, which can facilitate the attachment of the decorative piece on the shell. Moreover, the edge of the decorative piece does not need to form a wrapping structure, which can reduce the restriction on the material of the decorative piece, such as facilitating the attachment of the decorative piece with high strength such as metal sheet on the shell, reducing the difficulty and complexity of the attachment of such decorative piece on the shell, and ensuring the flatness of the attachment of the decorative piece and the appearance of the earphone box.

[0010] Moreover, the first convex edge structure and the shell are an integral structure, the first convex edge structure and the shell can be integrally formed to form an integral structure, which improves the stability and reliability of the first convex edge structure on the shell, makes the first convex edge structure have high mechanical properties and strength, and further facilitates the improvement of the high assembly firmness of the decorative piece and the shell.

[0011] In a possible implementation, the outer surface of the shell includes an arc surface, that is, at least part of the outer surface of the shell can be an arc surface, and the at least part of the outer surface is a surface with bending characteristics, has a curvature, and the cross-sectional shape can be arc-shaped.

[0012] The outer surface of the shell further has a second raised edge structure, the second raised edge structure is arranged protruding from the outer surface of the shell, and the second raised edge structure divides the arc-shaped surface into at least two split surfaces. The split surfaces can also be arc-shaped, that is, surfaces with bending characteristics and curvature. The decorative piece includes at least two split parts, the at least two split parts are correspondingly attached to the at least two split surfaces, and the second raised edge structure is located between the two adjacent split parts. The second raised edge structure is attached to the two opposite side surfaces of the split parts, so that the second raised edge structure is attached and spliced with the split parts.

[0013] It can be understood that the decorative piece is attached to the outer surface of the shell, and the interior of the decorative piece can enclose a containing space for accommodating the shell. The decorative piece is divided into at least two split parts, and the interior of each split part can enclose a relatively small sub-space. Each split part is attached to the corresponding split surface, so that each split part is spliced to form the entire decorative piece, and the sub-spaces of each split part are spliced to form the containing space in the decorative piece, achieving the attachment and assembly of the entire decorative piece on the outer surface of the shell. This is conducive to reducing the difficulty and complexity of forming the decorative piece, especially in the case where the size of the shell and the decorative piece is large and the interior of the decorative piece needs to enclose a relatively large containing space. The split parts with smaller sub-spaces are easier to form. Moreover, the split parts have higher processing precision in terms of size and shape, and have higher yield rates, which is conducive to reducing the assembly gap between the decorative piece and the second raised edge structure, the first raised edge structure, etc., and improving the integrity and aesthetics of the splicing between the decorative piece and the first raised edge structure, the second raised edge structure, etc. If the material of the decorative piece is a metal sheet and is formed by stamping, the split parts with smaller sub-spaces are easier to form, and the formed split parts have higher processing precision and yield rates.

[0014] The second raised edge structure can also function as a positioning element, effectively controlling the assembly gap between the split parts and the second raised edge structure, ensuring that the two opposite side surfaces of the second raised edge structure and the split parts can be well attached, improving the integrity between the entire decorative piece and the second raised edge structure, and being conducive to improving the overall appearance and aesthetics of the earphone case.

[0015] The second convex edge structure divides a relatively large arc surface into a plurality of relatively small sub-surface, and a plurality of sub-pieces are correspondingly attached to the sub-surface to splice into an integral decorative piece. The second convex edge structure can also decouple the tolerances caused by processing and splicing assembly between the sub-pieces. Compared with directly splicing the sub-pieces to form an entire decorative piece without the second convex edge structure, controlling the assembly gap between the sub-pieces and the second convex edge structure can reduce or avoid the influence of the processing and splicing assembly tolerance of one sub-piece on the splicing assembly tolerance of another sub-piece, resulting in a larger or uneven gap between the other sub-piece and other structures (such as other sub-pieces or the first convex edge structure, etc.), which is more conducive to improving the overall appearance and aesthetics of the earphone case, and is conducive to reducing the processing and assembly precision requirements of each sub-piece, facilitating molding.

[0016] In addition, the sub-pieces are attached to the small-sized sub-surface, each sub-piece covers a smaller area, and the sub-pieces need to adapt to less changes in the arc surface, so the cumulative attachment error and deformation influence in the process of attaching the sub-pieces is smaller. Moreover, on the small-sized sub-surface, the sub-pieces are less likely to produce uneven stress distribution when adapting to the curvature change of the sub-surface, and attaching the sub-pieces on the small-sized sub-surface is more convenient to operate, easier to control and adjust during the attachment process, and also helps to reduce the problem of uneven stress distribution. These can reduce the probability of wrinkles on the sub-pieces, improve the smoothness of the entire decorative piece on the surface of the shell, and also improve the aesthetics of the earphone case.

[0017] In one possible implementation, the second convex edge structure, the first convex edge structure, and the shell are an integral structure. That is, the first convex edge structure, the second convex edge structure, and the shell are an integral structure, and the first convex edge structure, the second convex edge structure, and the shell can be integrally formed into an integral structure, improving the stability of the second convex edge structure on the shell, making the second convex edge structure have high mechanical properties and strength, and improving the use experience and service life of the earphone case.

[0018] In one possible implementation, the first convex edge structure is connected to the second convex edge structure, so that the first convex edge structure and the second convex edge structure are connected into an integral whole, which is conducive to improving the aesthetics of the earphone case. Moreover, the first convex edge structure and the second convex edge structure have higher mechanical properties and strength, improving the assembly firmness of the decorative piece on the shell and improving the reliability of the earphone case.

[0019] In one possible implementation, the shell has an assembly hole on the outer surface, and the assembly hole penetrates the second convex edge structure. The second convex edge structure includes a main body portion and a first extension portion connected to each other, and the first extension portion surrounds the assembly hole.

[0020] By setting the protruding first extension part around the assembly hole position, the assembly gap between the split part and the protruding first extension part is easier to control, and the assembly gap of the split part at the assembly hole position is reduced. Compared with not setting the first extension part and directly splicing the two split parts at the assembly hole position, the machining and splicing assembly tolerance of one of the split parts can reduce or avoid the influence of the splicing assembly tolerance of the other split part at the assembly hole position, so that the other split part has a larger splicing gap or uneven gap with the edge of the assembly hole, which is beneficial to improve the appearance of the earphone box.

[0021] In a possible implementation, the assembly hole includes a first hole structure, the first hole structure is arranged adjacent to the first protruding edge structure, and the first protruding edge structure and the first extension part surrounding the first hole structure have a gap. The second protruding edge structure further includes a second extension part, the second extension part is located in the gap, and the second extension part is connected with the first protruding edge structure and the first extension part surrounding the first hole structure respectively, so as to realize the connection of the second protruding edge structure and the first protruding edge structure and ensure the high mechanical performance and strength of the first protruding edge structure and the second protruding edge structure.

[0022] In a possible implementation, the second extension part includes first and second opposite side surfaces, and the first and second side surfaces are respectively attached to two adjacent split parts. The first extension part surrounding the first hole structure includes third and fourth opposite side surfaces, and the third and fourth side surfaces are respectively attached to two adjacent split parts.

[0023] The first side surface and the third side surface form a smooth surface, and the second side surface and the fourth side surface form a smooth surface. In this way, the side surfaces of the split parts attached to the first extension part and the second extension part can also be smooth surfaces, which can be continuous and have no obvious concave-convex or protruding parts. This is beneficial to simplify the shape structure design of the split parts at the corresponding positions attached to the first extension part and the second extension part, reduce the molding difficulty of the split parts and the assembly difficulty of the split parts at the corresponding positions of the first hole structure, improve the assembly accuracy of the split parts, more easily control the assembly gap between the split parts and the first protruding edge structure and the second protruding edge structure, and improve the overall and appearance of the earphone box.

[0024] In a possible implementation, the second protruding edge structure uniformly divides the arc surface into two split surfaces, and the two split surfaces are symmetrically arranged with the second protruding edge structure as the symmetry axis. In this way, the two split surfaces can also be symmetrically arranged with the two split parts corresponding to the two split surfaces, and the shapes and sizes of the two split parts can be the same, which is beneficial to the molding of the split parts.

[0025] In addition, the second convex edge structure uniformly and symmetrically divides the arc surface, has better aesthetics, and the curvature change of the arc surface is also uniformly divided, and the stress distribution generated on the two split surfaces is also uniformly corresponding, which is beneficial to reduce the probability of wrinkles generated on each split part, and is more beneficial to improve the aesthetics of the earphone box.

[0026] In a possible implementation, the arc surface includes oppositely arranged first and second arc surfaces, and the first convex edge structure extends from the first arc surface to the second arc surface, and the first convex edge structure uniformly divides the first and second arc surfaces into two split surfaces respectively. In this way, one second convex edge structure can uniformly divide the first and second arc surfaces into two split surfaces respectively, the number of the second convex edge structures protruding on the outer surface of the shell can be reduced, and the integrity and aesthetics of the earphone box can be improved.

[0027] In a possible implementation, the curvature radius of the arc surface is less than 5. The arc surface has a smaller curvature radius, the bending degree of the arc surface is larger, the shell has better appearance effect, the second convex edge structure is formed on the shell, the fitting assembly of the decorative piece on the shell with the arc surface having a large bending degree can be facilitated, the applicable range of the unique appearance characteristic design of the earphone box by using the decorative piece is expanded, and the appearance characteristic of the earphone box with the arc outer surface is enriched.

[0028] In a possible implementation, the decorative piece includes at least one of a metal sheet and a leather sheet. Under the condition of meeting the miniaturization design requirement and the fitting flatness requirement of the shell and the earphone box, the fitting assembly of the decorative piece of the metal sheet, the leather sheet or the like on the shell can be facilitated, the earphone box can be given a unique appearance effect such as metal texture and leather texture, and a good touch feeling can be provided.

[0029] A second aspect of the embodiments of the present application provides an earphone assembly, including a wireless earphone and the earphone box of any one of the above.

[0030] It should be understood that the second aspect of the present application corresponds to the technical solution of the first aspect of the present application, and the beneficial effects obtained by each aspect and the corresponding feasible implementation are similar, which will not be repeated.

[0059] For example, as shown in Figure 1 and Figure 2 The earphone box 100 can include a first shell assembly 101 and a second shell assembly 102. The first shell assembly 101 and the second shell assembly 102 can jointly enclose an accommodation space (not shown in the figure) for accommodating the wireless earphone and the structural components of the earphone box 100.

[0060] In some examples, the first shell assembly 101 and the second shell assembly 102 can be arranged in sequence, for example, for the convenience of description, in the embodiment of the present application, the height direction (such as z direction) of the earphone box 100 is taken as the direction of the sequence of the first shell assembly 101 and the second shell assembly 102. Figure 1In the z direction shown in the figure, the first shell assembly 101 and the second shell assembly 102 can be sequentially distributed in the height direction (such as the z direction) (such as the z direction). In the width direction (such as the x direction) of the earphone box 100 Figure 1 In the x direction shown in the figure, the length direction (such as the y direction) of the earphone box 100 is Figure 1 In the y direction shown in the figure, the height direction (such as the z direction), the length direction (such as the y direction), and the width direction (such as the x direction) can be perpendicular to each other.

[0061] It can be understood that the length, width, and thickness in the embodiments of the present application are only for the convenience of description, and do not mean any limitation on the size, for example, the length can be greater than, equal to, or less than the width.

[0062] The earphone box 100 can be a foldable earphone box, and the earphone box 100 can include an open state and a closed state. As shown in Figure 1 As shown in the figure, when the earphone box 100 is in the closed state, the second shell assembly 102 can be covered on the first shell assembly 101, and the second shell assembly 102 and the first shell assembly 101 can be tightly attached, so that a closed containing space can be formed in the second shell assembly 102 and the first shell assembly 101.

[0063] When the earphone box 100 is in the open state, the second shell assembly 102 can be opened relative to the first shell assembly 101, so that the internal containing space is exposed. The user can also put the wireless earphone into the containing space of the earphone box 100, or when the wireless earphone is located in the containing space of the earphone box 100, the wireless earphone can be exposed and presented, and the user can take out the wireless earphone.

[0064] In some examples, the first shell assembly 101 and the second shell assembly 102 can be hingedly connected. For example, the earphone box 100 can further include a hinge mechanism (not shown in the figure), and the first shell assembly 101 and the second shell assembly 102 can be connected with the hinge mechanism respectively, and the first shell assembly 101 and the second shell assembly 102 can be rotationally matched through the hinge mechanism. The second shell assembly 102 can be rotated relative to the first shell assembly 101, and then the second shell assembly 102 can be covered on the first shell assembly 101, or the second shell assembly 102 can be opened relative to the first shell assembly 101, so as to realize the switching of the earphone box 100 between the open state and the closed state.

[0065] In the figure, the first shell assembly 101 and the second shell assembly 102 can be hingedly connected. Figure 2As shown, the first shell assembly 101 can include a first base shell 1011 and a first decorative sheet 1012. The first base shell 1011 can have an inner portion that encloses a first accommodating cavity 101c, which can be part of the accommodating space in the earphone case 100, for accommodating the wireless earphones and / or other structural members of the earphone case 100. One end of the first base shell 1011 can have a first opening 101d that is in communication with the first accommodating cavity 101c. For example, along the height direction (e.g., the z direction), one end of the first base shell 1011 has the first opening 101d, through which the wireless earphones and / or other structural members of the earphone case 100 can be placed into the first accommodating cavity 101c.

[0066] The first base shell 1011 can include an inner surface 101b and an outer surface 101a. The inner surface 101b of the first base shell 1011 can face the first accommodating cavity 101c and can serve as a cavity wall surface of the first accommodating cavity 101c. The outer surface 101a of the first base shell 1011 is opposite to the inner surface 101b of the first base shell 1011.

[0067] The first decorative sheet 1012 can be disposed on the outer surface 101a of the first base shell 1011. The side of the first decorative sheet 1012 that faces away from the first base shell 1011 can form at least part of the appearance surface of the first shell assembly 101. The first decorative sheet 1012 can have a color, pattern, texture, tactile sensation, or visual effect design. The first decorative sheet 1012 can impart the color, pattern, texture, tactile sensation, or visual effect design to the first shell assembly 101, thereby improving the aesthetic appearance of the first shell assembly 101 and the entire earphone case 100. The first decorative sheet 1012 can also protect the first base shell 1011.

[0068] Correspondingly, the second shell assembly 102 can include a second base shell 1021 and a second decorative sheet 1022. The second base shell 1021 can have an inner portion that encloses a second accommodating cavity (not shown in the figure), which can be part of the accommodating space, for accommodating the wireless earphones and / or other structural members of the earphone case 100. One end of the second base shell 1021 can have a second opening (not shown in the figure) that is in communication with the second accommodating cavity. For example, along the height direction (e.g., the z direction), one end of the second base shell 1021 has the second opening, through which the wireless earphones and / or other structural members of the earphone case 100 can be placed into the second accommodating cavity.

[0069] The second base shell 1021 can include an inner surface (not shown in the figure) and an outer surface 102a, the inner surface of the second base shell 1021 can face the second accommodating cavity, and the inner surface of the second base shell 1021 can serve as a cavity wall surface of the second accommodating cavity. The outer surface 102a of the second base shell 1021 is opposite to the inner surface of the second base shell 1021.

[0070] The second decorative sheet 1022 can be arranged on the outer surface 102a of the second base shell 1021, and the side of the second decorative sheet 1022 facing away from the second base shell 1021 can form at least part of the appearance surface of the second shell assembly 102. The second decorative sheet 1022 can impart appearance characteristics such as color, pattern, texture, tactile feel, or visual effect design to the second shell assembly 102, and also provide protection for the second base shell 1021.

[0071] In some examples, the first shell assembly 101 can further include a first inner shell (not shown in the figure), which can be arranged in the first accommodating cavity 101c of the first base shell 1011, and the first inner shell can have a first accommodating groove thereon.

[0072] The second shell assembly 102 can further include a second inner shell (not shown in the figure), which can be arranged in the second accommodating cavity of the second base shell 1021, and the second inner shell can have a second accommodating groove thereon. The first accommodating groove and the second accommodating groove can be used together to accommodate and fix the wireless earphone, so that the wireless earphone can be stably stored in the earphone box 100.

[0073] The earphone box 100 can further include a main control board (not shown in the figure), which can be accommodated in the first accommodating cavity 101c of the first shell assembly 101, such as in the space between the first inner shell and the first shell assembly 101 in some examples. The main control board can include a processor, a controller, etc.

[0074] The first shell assembly 101 can be provided with a control button (not shown in the figure), which can be connected with the main control board, and the control button can be used to control the earphone box 100 and the wireless earphone.

[0075] The earphone box 100 can further include a battery, a charging management module, etc., to meet the endurance requirements of the earphone box 100, and also to charge the wireless earphone. In some examples, the battery, the charging management module, etc. can also be accommodated in the first accommodating cavity 101c of the first shell assembly 101, such as in the space between the first inner shell and the first shell assembly 101.

[0076] The first shell assembly 101 can further have an interface 103, which can be used to connect a charger. The charging management module can receive charging input from the charger through the interface to charge the battery.

[0077] It can be understood that the structure shown in the embodiments of the present application does not constitute a specific limitation of the earphone box 100. In other embodiments of the present application, the earphone box 100 can include more or fewer components than shown, or combine certain components, or split certain components, or different component arrangements. For example, the earphone box 100 can also include sensors, communication modules, indicator lights, and other structural components.

[0078] At present, the decorative sheet (such as the first decorative sheet and the second decorative sheet described above) on the base shell (such as the first base shell and the second base shell described above) is mostly covered on the outer surface of the base shell by the edge covering process. For example, the decorative sheet is attached to the outer surface of the base shell, and the decorative sheet can cover the entire outer surface of the base shell. A U-shaped edge covering structure can be formed at the edge of the decorative sheet, and the edge covering structure can wrap around the edge of the base shell. For example, the edge portion of the decorative sheet can be bent inwardly to form an edge covering structure. Part of the edge covering structure will be accommodated in the accommodating cavity (such as the first accommodating cavity and the second accommodating cavity described above) surrounded by the base shell and attached to the inner surface of the base shell. This can avoid the edge of the decorative sheet from being exposed and causing wear and tear or edge lifting, and ensure the assembly firmness of the decorative sheet and the base shell. However, the part of the edge covering structure located in the accommodating cavity will occupy the space in the accommodating cavity, which is not conducive to the layout design of the wireless earphone and other structural components in the earphone box, and cannot meet the miniaturization design requirements of the earphone box.

[0079] Therefore, the embodiments of the present application provide an earphone box. The earphone box comprises a shell, an adhesive layer and a decorative piece. The decorative piece is attached to the outer surface of the shell through the adhesive layer, and the outer surface of the shell has a first raised edge structure. The first raised edge structure is an integral structure with the shell. The first raised edge structure is located at the edge of one end of the shell having an opening. The first raised edge structure surrounds the opening. The decorative piece is located at one side of the first raised edge structure. The two sides of the decorative piece opposite to the first raised edge structure are attached, so that the decorative piece is spliced with the first raised edge structure. The raised first raised edge structure can hide and shield the edge of the decorative piece to some extent, reduce or avoid the edge of the decorative piece from being exposed and causing wear and tear, and also avoid the edge of the decorative piece from being exposed and causing edge lifting, so as to ensure the high assembly firmness between the decorative piece and the shell. In this way, the edge of the decorative piece does not need to form an edge covering structure, and the decorative piece will not extend into the accommodating cavity of the shell. This can avoid the decorative piece from occupying the space in the accommodating cavity of the shell, facilitate the layout design of other structural components in the accommodating cavity, and facilitate the miniaturization design of the shell and the earphone box. Moreover, the edge portion of the decorative piece does not need to be bent inwardly to form an edge covering structure, which can reduce or avoid the wrinkle problem caused by bending the edge of the decorative piece, facilitate the flatness of the decorative piece attached to the outer surface of the shell, and improve the aesthetics of the earphone box.

[0080] Furthermore, the raised first edge structure also serves a positioning function, facilitating the attachment of decorative parts to the housing. The edges of the decorative parts do not require a binding structure, reducing constraints on the material of the decorative parts. For example, it facilitates the attachment of high-strength decorative parts such as metal sheets to the housing, reducing the difficulty and complexity of assembly and ensuring a smooth fit and aesthetic appeal of the headphone case. The first raised edge structure forms an integral part with the housing, giving it high mechanical properties and strength, thus ensuring a high degree of secure assembly between the decorative parts and the housing.

[0081] The housing can be the first base shell described above, and the decorative element can be the first decorative piece described above. Alternatively, the housing can be the second base shell described above, and the decorative element can be the second decorative piece described above.

[0082] Figure 3 for Figure 2 A schematic diagram of the split structure of the first shell component.

[0083] For example, taking the housing 10 as the first base housing 1011, see... Figure 3 As shown, the side of the housing 10 facing away from the internal receiving cavity 140 (such as the first receiving cavity 101c) is the outer surface 110 (such as the outer surface 101a) of the housing 10. The outer surface 110 of the housing 10 has a first protruding edge structure 11. The first protruding edge structure 11 can be located at the edge of one end of the housing 10 that has an opening 130 (such as the first opening 101d). The first protruding edge structure 11 can be arranged around the opening 130. For example, in some examples, the first protruding edge structure 11 can be arranged around the opening 130, so that the outer contour shape of the first protruding edge structure 11 can be a closed ring.

[0084] The first convex edge structure 11 is located on the outer surface 110 of the housing 10, and the first convex edge structure 11 can protrude from the outer surface 110 of the housing 10. The first end of the first convex edge structure 11 can be fixed to the outer surface 110 of the housing 10, and the second end of the first convex edge structure 11 can protrude and extend a certain height away from the outer surface 110 of the housing 10. The first convex edge structure 11 can be a protrusion structure on the outer surface 110 of the housing 10. Taking the shell thickness direction of the housing 10 as the direction perpendicular to the inner surface 120 and the outer surface 110 of the housing 10, then in the shell thickness direction of the housing 10, the distance between the end face of the first convex edge structure 11 away from the outer surface 110 of the housing 10 (i.e., the second end) and the inner surface 120 of the housing 10 is greater than the distance between the outer surface 110 and the inner surface 120 of the housing 10, so that the first convex edge structure 11 is higher than the outer surface 110 of the housing 10.

[0085] Figure 4 for Figure 2A cross-sectional structural schematic view of the first shell assembly, Figure 5 To Figure 4 A partial structural enlarged schematic view of the A part.

[0086] The earphone box 100 can further include an adhesive layer 30, in combination Figure 4 And Figure 5 As shown, the adhesive layer 30 can be located between the decorative piece 20 (such as the first decorative sheet 1012) and the outer surface 110 of the shell 10, and the decorative piece 20 can be pasted on the outer surface 110 of the shell 10 through the adhesive layer 30, so that the decorative piece 20 can be fixedly attached to the outer surface 110 of the shell 10, realizing the attached assembly between the decorative piece 20 and the shell 10. The use of the adhesive layer 30 realizes the assembly of the decorative piece 20 on the shell 10, and gives the shell 10 color, pattern, texture, texture, or visual effect design, etc. Appearance characteristics, which is beneficial to improve the flexibility and beauty of the appearance design of the shell 10, has low cost and is easy to produce.

[0087] Referring to Figure 4 As shown, the first convex edge structure 11 is located at the edge of one end of the shell 10 with the opening 130, and the decorative piece 20 is attached to the outer surface 110 of the shell 10, so that the decorative piece 20 can be located on one side of the first convex edge structure 11, for example, along the height direction (such as the z direction), the decorative piece 20 can be located on one side of the first convex edge structure 11. In combination Figure 5 As shown, the two sides of the decorative piece 20 opposite to the first convex edge structure 11 are attached, such as along the height direction (such as the z direction), the side of the decorative piece 20 facing the first convex edge structure 11 and the side of the first convex edge structure 11 facing the decorative piece 20 are attached and contacted, so that the decorative piece 20 is spliced with the first convex edge structure 11. The first convex edge structure 11 provided in a convex manner can play a certain hiding and shielding role for the edge of the decorative piece 20 (such as the part attached to the first convex edge structure 11), reducing or avoiding the problem of wear caused by the edge of the decorative piece 20 exposed, and also can avoid the phenomenon that the edge of the decorative piece 20 is easily exposed and warped, so as to ensure the high assembly firmness between the decorative piece 20 and the shell 10.

[0088] Thus, the edge of the decoration piece 20 does not need to form a wrapping structure, the decoration piece 20 is attached to the outer surface 110 of the shell 10 and does not extend into the accommodation cavity 140 of the shell 10, which can avoid the decoration piece 20 occupying the space of the accommodation cavity 140 inside the shell 10, especially in the example that the material of the decoration piece 20 is a relatively thick leather sheet, which can significantly reduce the space occupied by the decoration piece 20 inside the shell 10, facilitate the layout design of other structural parts in the accommodation cavity 140, and facilitate the miniaturization design of the shell 10 and the earphone box 100. Moreover, the edge part of the decoration piece 20 does not need to be bent into the accommodation cavity 140 to form a wrapping structure, which can reduce or avoid the wrinkle problem caused by the bending of the edge of the decoration piece 20, facilitate the flatness of the decoration piece 20 attached to the outer surface 110 of the shell 10, and improve the appearance of the earphone box 100.

[0089] In addition, the first raised edge structure 11 arranged in a protruding manner can also play a positioning role, which can facilitate the attachment of the decoration piece 20 on the shell 10. Moreover, the edge of the decoration piece 20 does not need to form a wrapping structure, which can reduce the restriction on the material of the decoration piece 20, such as facilitating the attachment of the decoration piece 20 with a high-strength material such as a metal sheet on the shell 10, which can facilitate the attachment and assembly of the decoration piece 20 with a material such as a metal sheet on the shell 10, and ensure the flatness of the decoration piece 20 and the appearance of the earphone box 100.

[0090] For example, the material of the decoration piece 20 can include but is not limited to at least one of a metal sheet, a leather sheet, etc. Under the condition of meeting the miniaturization design requirement and the flatness requirement of the shell 10 and the earphone box 100, the attachment and assembly of the decoration piece 20 with a material such as a metal sheet or a leather sheet on the shell 10 can be facilitated, which can also give the earphone box 100 a unique appearance effect such as a metal texture or a leather texture, and provide a good touch.

[0091] Of course, in some other examples, the material of the decoration piece 20 can also be other types of materials, such as a plastic sheet, a rubber sheet, a glass sheet, etc.

[0092] The first raised edge structure 11 and the shell 10 are an integral structure, and the first raised edge structure 11 and the shell 10 can be integrally formed into an integral structure, which can improve the stability and reliability of the first raised edge structure 11 on the shell 10, make the first raised edge structure 11 have high mechanical properties and strength, and thus facilitate the high assembly firmness of the decoration piece 20 and the shell 10.

[0093] For example, during the molding process of the housing 10, a raised first protruding edge structure 11 can be formed on the outer surface 110 of the housing 10 using a mold or similar tool. Exemplarily, injection molding can be used to form an integral structural component of the housing 10 and the first protruding edge structure 11, providing greater flexibility in the structural shape design of the housing 10 and the first protruding edge structure 11, ensuring consistency between the housing 10 and the first protruding edge structure 11, and improving the mechanical properties and strength of the housing 10 and the first protruding edge structure 11. Furthermore, it helps to reduce the complexity of the molding process and production costs.

[0094] For example, in the actual assembly process, an integral structural component consisting of a housing 10, a first protruding edge structure 11, and a decorative component 20 can be formed separately. It is understood that the contour shape and size of the inner surface (the side facing the housing 10) of the decorative component 20 can match the contour shape and size of the outer surface 110 of the housing 10. Then, the decorative component 20 is attached to the outer surface 110 of the housing 10 through an adhesive layer 30, so that the decorative component 20 is located on one side of the first protruding edge structure 11, and the two opposite sides of the decorative component 20 are attached to each other.

[0095] In some examples, the height of the first protruding edge structure 11 protruding on the outer surface 110 of the housing 10 may be equal to or slightly lower than the sum of the heights of the decorative element 20 and the adhesive layer 30 covering the outer surface 110.

[0096] Figure 6 for Figure 4 A front view of the cross-sectional layout structure of the first shell component.

[0097] For example, see Figure 6 As shown, the height d1 of the first protruding edge structure 11 protruding on the outer surface 110 of the housing 10 can be considered as the distance between the end face of the first protruding edge structure 11 away from the housing 10 (i.e., the second end) and the outer surface 110 of the housing 10 along the thickness direction of the housing 10. The sum of the heights of the decorative element 20 and the adhesive layer 30 can be considered as d2, which can be the distance between the side of the decorative element 20 facing away from the housing 10 and the outer surface 110 of the housing 10 along the thickness direction of the housing 10.

[0098] Exemplarily, the first convex edge structure 11 can satisfy: 0mm≤d1-d2≤0.02mm. The height of the first convex edge structure 11 protruding from the outer surface 110 of the shell 10 is less than the sum of the height of the decorative piece 20 and the height of the adhesive layer 30. The side of the first convex edge structure 11 away from the outer surface 110 of the shell 10 is as flush as the side of the decorative piece 20 away from the shell 10, which improves the flatness and smoothness of the appearance of the first base shell 1011 and improves the appearance and touch of the earphone box 100.

[0099] In some examples, the height d1 of the first convex edge structure 11 protruding from the outer surface 110 of the shell 10 can be equal to the sum d2 of the height of the decorative piece 20 and the height of the adhesive layer 30. The side of the first convex edge structure 11 away from the outer surface 110 of the shell 10 is as flush as the side of the decorative piece 20 away from the shell 10, which improves the flatness and smoothness of the appearance of the first base shell 1011 and improves the overall appearance of the earphone box 100.

[0100] Figure 7 For Figure 2 the first base shell and the first decorative piece in the first shell assembly.

[0101] In some examples, referring to Figure 7 , the outer surface 110 of the shell 10 (such as the first base shell 1011) can include an arc surface 111, that is, at least part of the outer surface 110 of the shell 10 can be the arc surface 111. At least part of the outer surface 110 is a surface with bending characteristics and has curvature. The cross-sectional shape can be arc-shaped.

[0102] The outer surface 110 of the shell 10 also has a second convex edge structure 12, which can protrude from the outer surface 110 of the shell 10. The third end of the second convex edge structure 12 can be fixed to the outer surface 110 of the shell 10, and the fourth end of the second convex edge structure 12 can protrude and extend a certain height away from the outer surface 110 of the shell 10. The second convex edge structure 12 can be a protruding structure on the outer surface 110 of the shell 10. In the shell thickness direction of the shell 10, the distance between the end (i.e., the fourth end) of the second convex edge structure 12 away from the outer surface 110 of the shell 10 and the inner surface 120 of the shell 10 is greater than the distance between the outer surface 110 of the shell 10 and the inner surface 120 of the shell 10, so that the second convex edge structure 12 is higher than the outer surface 110 of the shell 10.

[0103] As Figure 7As shown in FIG. 1, the second convex edge structure 12 is located on the arc surface 111, and the second convex edge structure 12 divides the arc surface 111 into at least two sub-surface 1111. The sub-surface 1111 can also be arc-shaped, that is, a surface with a bending feature, and has a curvature.

[0104] The decorative piece 20 (such as the first decorative sheet 1012) can include at least two sub-pieces 21, which can be correspondingly attached to the at least two sub-surfaces 1111, that is, the number of sub-pieces 21 and sub-surfaces 1111 can be in a one-to-one correspondence relationship, that is, one sub-surface 1111 corresponds to one sub-piece 21, and the second convex edge structure 12 is located between the adjacent two sub-pieces 21, and the two side surfaces of the second convex edge structure 12 are attached to the sub-pieces 21.

[0105] For example, Figure 7 As shown in FIG. 1, the second convex edge structure 12 divides the arc surface 111 into two sub-surfaces 1111, such as sub-surface 1111a and sub-surface 1111b. The decorative piece 20 can include two sub-pieces 21, such as sub-piece 21a and sub-piece 21b. The sub-piece 21a can be attached to the sub-surface 1111a, and the sub-piece 21b can be attached to the sub-surface 1111b. The sub-piece 21a and the sub-piece 21b are adjacent, and the second convex edge structure 12 is located between the sub-piece 21a and the sub-piece 21b.

[0106] Figure 7a For Figure 2 Another cross-sectional structure schematic diagram of the first shell assembly.

[0107] In combination Figure 7a As shown in FIG. 1, the sub-piece 21a and the sub-piece 21b are located on the two sides of the second convex edge structure 12, for example, along the width direction (such as the x direction) of the earphone box 100, the sub-piece 21a and the sub-piece 21b can be located on the two sides of the second convex edge structure 12, and the second convex edge structure 12 can include two side surfaces opposite in the width direction (such as the x direction). One of the side surfaces can face the sub-piece 21a and is attached to the surface of the sub-piece 21a facing the second convex edge structure 12. The other side surface can face the sub-piece 21b and is attached to the surface of the sub-piece 21b facing the second convex edge structure 12, so that the second convex edge structure 12 is attached to the sub-piece 21a and the sub-piece 21b respectively.

[0108] It can be understood that the decorative piece 20 covers the outer surface 110 of the shell 10, and the interior of the decorative piece 20 forms a containing space for containing the shell 10. For example, Figure 7As shown in the figures, the decorative piece 20 is split into at least two sub-pieces 21, and each sub-piece 21 can enclose a relatively small sub-space inside. Each sub-piece 21 is attached to the corresponding sub-surface 1111, and the sub-pieces 21 are spliced to form the entire decorative piece 20, and the sub-spaces of the sub-pieces 21 are spliced to form the accommodation space inside the decorative piece 20, so as to realize the attachment and assembly of the entire decorative piece 20 on the outer surface 110 of the shell. This is conducive to reducing the difficulty and complexity of forming the decorative piece 20, especially in the case where the size of the shell 10 and the decorative piece 20 is large, and a relatively large accommodation space needs to be enclosed inside the decorative piece 20. The sub-piece 21 with a smaller sub-space is easier to form, and the machining precision of the size and shape of the sub-piece 21 is higher, so that the yield of the finished product is higher. This is conducive to reducing the assembly gap between the decorative piece 20 and the second raised edge structure 12, the first raised edge structure 11, etc., and improving the integrity and aesthetics of the spliced decorative piece 20 and the first raised edge structure 11, the second raised edge structure 12, etc.

[0109] When the material of the decorative piece 20 is a metal sheet and is formed by stamping, the sub-piece 21 with a smaller sub-space is easier to form, and the sub-piece 21 after forming has higher machining precision and yield.

[0110] The second raised edge structure 12 can also function as a positioning element, effectively controlling the assembly gap between the sub-piece 21 and the second raised edge structure 12, ensuring that the two opposite sides of the second raised edge structure 12 and the sub-piece 21 can be well attached, improving the integrity between the entire decorative piece 20 and the second raised edge structure 12, and being conducive to improving the overall appearance and aesthetics of the earphone case 100.

[0111] The second raised edge structure 12 divides a relatively large arc surface 111 into a plurality of relatively small sub-surfaces 1111, and a plurality of sub-pieces 21 are attached to the sub-surfaces 1111 to splice into an entire decorative piece 20. The second raised edge structure 12 can also decouple the tolerances caused by machining and splicing assembly between the sub-pieces 21. Compared with the case where the second raised edge structure 12 is not provided and the entire decorative piece 20 is formed by directly attaching and splicing the sub-pieces 21, the assembly gap between the sub-pieces 21 and the second raised edge structure 12 can be controlled, which can reduce or avoid the influence of the machining and splicing assembly tolerance of one sub-piece 21 on the splicing assembly tolerance of another sub-piece 21, resulting in a large or uneven gap between the other sub-piece 21 and other structures (such as other sub-pieces 21 or the first raised edge structure 11, etc.). This is more conducive to improving the overall appearance and aesthetics of the earphone case 100, and is conducive to reducing the machining and assembly precision requirements of the sub-pieces 21 and facilitating the formation and implementation.

[0112] In addition, the sub-body part 21 is attached on the small-size sub-body surface 1111, each sub-body part 21 covers a small area, the sub-body part 21 needs to adapt to the change of the curvature of the arc surface is small, and the cumulative fitting error and deformation in the process of attaching the sub-body part 21 is small. And on the small-size sub-body surface 1111, the sub-body part 21 is not easy to produce uneven stress distribution when adapting to the curvature change of the sub-body surface 1111, attaching the sub-body part 21 on the small-size sub-body surface 1111 is more convenient to operate, and is easier to control and adjust in the process of attaching, and is also beneficial to reduce the problem of uneven stress distribution. These can reduce the probability of wrinkles on the sub-body part 21, improve the smoothness of the entire decorative part 20 on the outer surface 110 of the shell 10, and also improve the appearance of the earphone box 100.

[0113] The second convex edge structure 12 can be used to realize the attachment of the decorative part 20 on the arc surface 111 with large curvature, effectively control the assembly gap between the decorative part 20 and the second convex edge structure 12, reduce or avoid the problem of large assembly gap or uneven gap, and reduce the probability of wrinkles. The second convex edge structure 12 has a small width (such as the size of the second convex edge structure 12 in the width direction (such as the x direction)), which can also realize the attachment of the decorative part 20 on the shell 10, ensure that the earphone box 100 has a good appearance effect, and be beneficial to reducing the width of the second convex edge structure 12 and improving the consistency of the width of the second convex edge structure 12.

[0114] The width (such as the size of the first convex edge structure 11 in the height direction (such as the z direction)) of the first convex edge structure 11 can be consistent with the width of the second convex edge structure 12, so that the first convex edge structure 11 also has a small width and a high width consistency, which is beneficial to further improving the appearance of the earphone box 100.

[0115] In some examples, the curvature radius of the arc surface 111 included in the outer surface 110 of the shell 10 can be less than 5, so that the arc surface 111 has a small curvature radius, the arc surface 111 has a large curvature, and the shell 10 and the first shell assembly 101 can have a better appearance effect. The second convex edge structure 12 is formed on the shell 10, which can facilitate the attachment of the decorative part 20 on the shell 10 with a large curvature arc surface, expand the applicable range of the decorative part 20 for giving the earphone box 100 a unique appearance characteristic design, and enrich the appearance characteristics of the earphone box 100 with the arc outer surface 110.

[0116] The second raised edge structure 12 and the shell 10 are an integral structure, that is, the first raised edge structure 11, the second raised edge structure 12, and the shell 10 are an integral structure, and the first raised edge structure 11, the second raised edge structure 12, and the shell 10 can be integrally formed to form an integral structure, thereby improving the stability of the second raised edge structure 12 on the shell 10, and improving the mechanical properties and strength of the second raised edge structure 12, and improving the use experience and service life of the earphone box 100.

[0117] For example, in the process of forming the shell 10, the second raised edge structure 12 can be formed on the outer surface 110 of the shell 10 by means of a mold or the like. For example, the shell 10 with the first raised edge structure 11 and the second raised edge structure 12 can be integrally formed by injection molding. This has higher consistency and flexible structure design, and the process is simple and the cost is low.

[0118] The height of the second raised edge structure 12 protruding from the outer surface 110 of the shell 10 can be equal to or slightly lower than the sum of the heights of the decorative piece 20 and the adhesive layer 30 covering the outer surface 110. For example, the height of the second raised edge structure 12 can be equal to the height of the first raised edge structure 11, and the height of the second raised edge structure 12 can also be d1, and the sum d2 of the heights of the decorative piece 20 and the adhesive layer 30 can satisfy the relationship in the foregoing, which can be referred to in the foregoing and will not be described herein.

[0119] In some examples, the second raised edge structure 12 can uniformly divide the arc surface 111 of the shell 10 into two divided surfaces 1111, and the two divided surfaces 1111 can be symmetrically arranged, for example, the two divided surfaces 1111 can be symmetrically arranged with the second raised edge structure 12 as the axis of symmetry. In this way, the two divided surfaces 1111 can also be symmetrically arranged, and the shapes and sizes of the two divided surfaces 1111 can be the same, which facilitates the molding of the divided pieces 21. In addition, the second raised edge structure 12 uniformly and symmetrically divides the arc surface 111, which has better aesthetics, and the change in curvature of the arc surface 111 is also uniformly divided, and the stress distribution generated by the two divided surfaces 1111 is also uniformly corresponding, which is beneficial to reducing the probability of wrinkles on the divided pieces 21, and is more conducive to improving the aesthetics of the earphone box 100.

[0120] It should be noted that in some examples, the outer surface 110 of the shell 10 can be an arc surface 111 as a whole, and one or more second raised edge structures 12 can be protrudingly arranged on the outer surface 110 of the shell 10 to divide the arc surface 111 into a plurality of divided surfaces 1111.

[0121] Alternatively, in some examples, a portion of the outer surface 110 of the housing 10 can be an arcuate surface 111, and one or more second protruding edge structures 12 can be provided on the outer surface 110 of the housing 10 to divide the arcuate surface 111 into multiple split surfaces 1111. The second protruding edge structure 12 can extend to the remaining outer surface of the housing 10, so that the remaining outer surface of the housing 10 can be divided by the second protruding edge structure 12. For example, while the second protruding edge structure 12 divides the arcuate surface 111 into two uniformly symmetrical split surfaces 1111, it can also uniformly and symmetrically divide the remaining outer surface into two parts.

[0122] Of course, in some other examples, the second protruding edge structure 12 may not extend to the rest of the outer surface of the housing 10, and the rest of the outer surface of the housing 10 may be a single surface that is not divided by the second protruding edge structure 12.

[0123] In the example where a portion of the outer surface 110 of the housing 10 is an arc-shaped surface 111, the number of arc-shaped surfaces 111 can be one. Alternatively, the number of arc-shaped surfaces 111 can be multiple, and the multiple arc-shaped surfaces 111 can be distributed in a regular or irregular manner.

[0124] Figure 8 for Figure 7 A schematic diagram of the structure of the first base shell.

[0125] For example, Figure 8 The image shows an example where a portion of the outer surface 110 of the housing 10 is an arc-shaped surface 111, and there are two arc-shaped surfaces 111, such as a first arc surface 111a and a second arc surface 111b. The first arc surface 111a and the second arc surface 111b can be arranged opposite each other. For example, along the length direction (such as the y-direction) of the earphone case 100, the first arc surface 111a and the second arc surface 111b can be distributed sequentially and arranged opposite each other. The first arc surface 111a and the second arc surface 111b can serve as the portion of the outer surface of the housing 10 at opposite ends in the length direction (such as the y-direction).

[0126] In some examples, multiple curved surfaces 111 can be directly connected, such as... Figure 8 In the example of the first arc surface 111a and the second arc surface 111b, the first arc surface 111a and the second arc surface 111b can be directly connected to form a larger arc surface.

[0127] Alternatively, in some other examples, multiple curved surfaces 111 can be spaced out, and two adjacent curved surfaces 111 can be connected by planes or other types of curved surfaces.

[0128] In some examples, the curvature and curvature changes of multiple arc surfaces 111 can be approximately the same, and the multiple arc surfaces 111 can be symmetrically arranged. For example, if... Figure 8For example, the first arc surface 111a and the second arc surface 111b in the B part of FIG. 11 can be taken as an example. The curvatures and the curvature changes of the first arc surface 111a and the second arc surface 111b can be approximately the same. The first arc surface 111a and the second arc surface 111b can be symmetrically arranged. The symmetry axis can be the intersection line of the first arc surface 111a and the second arc surface 111b. This is beneficial to improve the symmetry and aesthetics of the shell 10.

[0129] In the example in which the arc surface 111 includes the first arc surface 111a and the second arc surface 111b arranged opposite to each other, referring to FIG. 11, Figure 8 As shown in FIG. 11, the second convex edge structure 12 can extend from the first arc surface 111a to the second arc surface 111b. For example, the second convex edge structure 12 can extend along the length direction (such as the y direction) from one end of the shell 10 to the other end. Part of the second convex edge structure 12 can be located on the first arc surface 111a, and the first arc surface 111a can be uniformly divided into two sub-surface 1111a and 1111b. Part of the second convex edge structure 12 can be located on the second arc surface 111b, and the second arc surface 111b can be uniformly divided into two sub-surface 1111c and 1111d. In this way, one second convex edge structure 12 can uniformly divide the first arc surface 111a and the second arc surface 111b into two sub-surface 1111 respectively. This can reduce the number of second convex edge structures 12 protruding on the outer surface 110 of the shell 10, and is beneficial to improve the integrity and aesthetics of the earphone box 100.

[0130] In some examples, the first convex edge structure 11 can be connected to the second convex edge structure 12, so that the first convex edge structure 11 and the second convex edge structure 12 are connected into one whole. This is beneficial to improve the aesthetics of the earphone box 100. In addition, the first convex edge structure 11 and the second convex edge structure 12 have higher mechanical properties and strength, which improves the assembly firmness of the decorative piece 20 on the shell 10 and improves the reliability of the earphone box 100.

[0131] Figure 9 For Figure 7 A partial structure enlarged schematic view of the B part in FIG. 11.

[0132] In some examples, referring to FIG. 11, Figure 9 As shown in FIG. 11, the outer surface 110 of the shell 10 can also have an assembly hole 13. The assembly hole 13 can be a through hole on the outer surface 110 of the shell 10. The assembly hole 13 can pass through the inner surface 120 and the outer surface 110 of the shell 10.

[0133] The assembly hole 13 can be used to realize the connection between the earphone box 100 and external devices. For example, the assembly hole 13 can form the interface mentioned above. Through the interface, the earphone box 100 and the charger can be connected, and then the charging of the battery and the like in the earphone box 100 can be realized.

[0134] Alternatively, the assembly hole 13 can also be used to connect other structural members such as a hanging rope, a decorative rope, a hanging member, etc.

[0135] The number of assembly holes 13 on the shell 10 can be one, or alternatively, the number of assembly holes 13 can also be multiple. For example, in some examples, the number of assembly holes 13 can be two, such as a first hole structure 131 and a second hole structure 132 (as shown in Figure 8 , the first hole structure 131 and the second hole structure 132 can be spaced apart.

[0136] Continuing to refer to Figure 9 , in some examples, the assembly hole 13 can be provided on the second convex edge structure 12, so that the assembly hole 13 can pass through the second convex edge structure 12.

[0137] The second convex edge structure 12 can include a main body portion 121 and a first extension portion 122 connected thereto, the first extension portion 122 can be provided around the assembly hole 13 (such as the first hole structure 131), and the first extension portion 122 is provided on the outer surface 110 of the part around the assembly hole 13. The first extension portion 122 is provided around the assembly hole 13.

[0138] Among them, the number of first extension portions 122 can be the same as the number of assembly holes 13, such as the example that the assembly hole 13 includes the first hole structure 131 and the second hole structure 132 (refer to Figure 8 , the number of first extension portions 122 can also be two, such as a first extension portion 122c and a first extension portion 122d, the first extension portion 122c and the first extension portion 122d can be respectively provided around the first hole structure 131 and the second hole structure 132. The two first extension portions 122 can be connected by the main body portion 121 to form an integral second convex edge structure 12.

[0139] It can be understood that the first extension portion 122 is provided around the assembly hole 13, and the two sides of the split body 21 opposite to the first extension portion 122 can be fitted and spliced (refer to Figure 7 , the profile shape of the part where the split body 21 is fitted with the first extension portion 122 corresponds to the outer profile shape of the first extension portion 122 and the assembly hole 13, so as to expose the assembly hole 13 as a whole under the condition of ensuring the aesthetics of the earphone box 100.

[0140] The first extension 122 is arranged around the assembly hole 13, which makes the assembly gap between the split part 21 and the first extension 122 easier to control, and reduces the assembly gap of the split part 21 at the position of the assembly hole 13. Compared with the direct assembly of two split parts 21 at the position of the assembly hole 13 without the first extension 122, the machining and assembly tolerance of one split part 21 does not affect the assembly tolerance of the other split part 21 at the position of the assembly hole 13, which can reduce or avoid the problem of large or uneven assembly gap between the other split part 21 and the edge of the assembly hole 13, and improve the appearance of the earphone box 100.

[0141] Continuing to refer to Figure 9 As shown, the first hole structure 131 can be arranged adjacent to the first convex edge structure 11, and the first hole structure 131 can have a certain spacing from the first convex edge structure 11, so that the first extension 122 around the first hole structure 131 can have a gap from the first convex edge structure 11.

[0142] The second convex edge structure 12 can further include a second extension 123, which is located in the gap between the first convex edge structure 11 and the first extension 122 around the first hole structure 131, and the second extension 123 is connected with the first convex edge structure 11 and the first extension 122 around the first hole structure 131 respectively, so as to realize the connection between the second convex edge structure 12 and the first convex edge structure 11, and ensure the high mechanical properties and strength of the first convex edge structure 11 and the second convex edge structure 12.

[0143] In some examples, the second extension 123 can include opposite first and second side surfaces 123a and 123b, which can be respectively attached to two adjacent split parts 21 (such as the split part 21a and the split part 21b) on both sides of the second convex edge structure. For example, the first side surface 123a of the second extension 123 can face and be attached to the split part 21a (not shown in the figure), and the second side surface 123b of the second extension 123 can face and be attached to the split part 21b (not shown in the figure).

[0144] The first extension 122 around the first hole structure 131 can include opposite third and fourth side surfaces 122a and 122b, which can also be respectively attached to the two split parts 21. For example, the third side surface 122a of the first extension 122 can face and be attached to the split part 21a, and the fourth side surface 122b of the first extension 122 can face and be attached to the split part 21b.

[0145] The first side surface 123a and the third side surface 122a are adjacent and connected, and can be joined to form a smooth surface. The second side surface 123b and the fourth side surface 122b are adjacent and connected, and can be joined to form a smooth surface. A smooth surface can refer to a surface that is continuous, without obvious unevenness or protrusions, making the surface visually and tactilely approximately uniform, without obvious interruptions or irregularities.

[0146] This allows the side of the split component 21 that fits against the first extension 122 and the second extension 123 to also be a smooth surface (see reference). Figure 7 As shown, this simplifies the shape and structure design of the split component 21 at the corresponding positions where it fits with the first extension 122 and the second extension 123, reduces the molding difficulty of the split component 21 and the assembly difficulty of the split component 21 at the corresponding position of the first hole structure 131, improves the assembly accuracy of the split component 21, makes it easier to control the assembly gap between the split component 21 and the first convex edge structure 11 and the second convex edge structure 12, and improves the overall integrity and aesthetics of the headphone box 100.

[0147] The above example illustrates the shell 10, the first convex edge structure 11, the second convex edge structure 12, and the decorative element 20, using the shell 10 as the first base shell 1011 and the decorative element 20 as the first decorative piece 1012. It should be noted that the structures and assembly relationships of the shell, the first convex edge structure, the second convex edge structure, and the decorative element described above can also be applied to examples where the shell is the second base shell and the decorative element is the second decorative piece.

[0149] For example, see Figure 10 As shown, in the example where the housing 10c is the second base shell 1021 and the decorative piece 20a is the second decorative piece 1022, the outer surface 110a (i.e., the outer surface 102a) of the housing 10c may also have a raised first protruding edge structure 11a. The first protruding edge structure 11a may be located at the edge of the housing 10c with an opening (such as a second opening), and the first protruding edge structure may be arranged around the opening. The decorative piece 20a may be attached to the outer surface 110a of the housing 10c by an adhesive layer (not shown in the figure). The decorative piece 20a (such as a second decorative piece) is located on one side of the first protruding edge structure 11a, and the two sides of the decorative piece 20a opposite to the first protruding edge structure 11a may be attached.

[0151] The outer surface 110a of the shell 10c can include an arc surface 111c, and the outer surface 110a of the shell 10c can have a second convex edge structure 12a, which can divide the arc surface 111c included in the outer surface 110a into at least two sub-surface (such as sub-surface 1111e and sub-surface 1111f), and the decorative piece 20a can include at least two sub-pieces (such as sub-piece 210a and sub-piece 210b).
