Description

Technical Field

[0001] The embodiments of the present application relate to the field of earphone technology, and in particular to an earphone box and an earphone assembly. Background Art

[0002] Wireless headphones, thanks to their portability and unrestricted user experience, have become an essential accessory for daily commuting, exercise, fitness, work, and study. As a companion device for wireless headphones, headphone cases not only effectively store and protect the headphones but also provide charging and pairing functions, leading to a growing number of applications. However, existing headphone cases are bulky and difficult to carry. Utility Model Content

[0003] The embodiments of the present application provide an earphone box and an earphone assembly, which can reduce the volume of the earphone box to a certain extent.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] In a first aspect, an embodiment of the present application provides an earphone case comprising a first portion. The first portion has a width direction, a thickness direction, and a height direction. The first portion comprises a first shell and an inner lining. At least a portion of the inner lining is disposed within the first shell. The inner lining comprises a first accommodating cavity, a second accommodating cavity, and a first spacer. In the thickness direction, a portion of the first accommodating cavity and a portion of the second accommodating cavity are separated by the first spacer.

[0006] By adopting this solution, at least parts of the first accommodating cavity and the second accommodating cavity are spaced apart in the thickness direction and separated by the first spacing portion, so that the first earphone and the second earphone can use the middle area of ​​the earphone box together for cross placement. In this way, the combined structure formed by the first accommodating cavity and the second accommodating cavity and the spacing space therebetween can have a maximum dimension in the width direction that is smaller than the sum of the dimensions of the first accommodating cavity and the second accommodating cavity in the width direction, thereby reducing the volume of the earphone box to a certain extent, facilitating the miniaturized design of the earphone box, and making the earphone box easy to carry.

[0007] Among them, the setting of the first spacer can, on the one hand, separate at least part of the spacing portion of the first accommodating cavity and the second accommodating cavity in the thickness direction, so that after the earphone is placed in, the first earphone and the second earphone can be at least partially separated, so that there is a certain distance between the two earphones, and they will not affect each other when taking and placing; on the other hand, the setting of the first spacer can also play a certain supporting role for the earphone, reducing the risk of the earphone falling over after being placed in the earphone box, and can make the earphone better fixed in the corresponding position, which helps to place the earphone stably.

[0008] In some possible implementation manners of the first aspect, a part of the first accommodating cavity spaced from the second accommodating cavity by the first spacing part is referred to as a first cavity, and a part of the first accommodating cavity other than the first cavity is referred to as a second cavity. A part of the second accommodating cavity spaced from the first accommodating cavity by the first spacing part is referred to as a third cavity, and a part of the second accommodating cavity other than the third cavity is referred to as a fourth cavity. The first cavity has a maximum thickness smaller than a maximum thickness of the second cavity; and / or, the third cavity has a maximum thickness smaller than a maximum thickness of the fourth cavity.

[0009] In this way, the first cavity and the third cavity have a smaller thickness, and can be used to accommodate at least part of the connecting arm of the earphone. The second cavity and the fourth cavity have a larger thickness, and can be used to accommodate at least part of the first earphone body of the earphone. In this way, on one hand, the earphone can be placed in a vertical manner in the earphone box, so that the earphone box has a smaller size in the width direction. On the other hand, the first cavity and the third cavity located in the middle region of the earphone box have a smaller thickness, and the second cavity and the fourth cavity located at the end of the earphone box have a larger thickness, so that the connecting arms of the two earphones can be arranged in a crossing manner, thereby reducing the size of the first accommodating cavity and the second accommodating cavity in the thickness direction, and further reducing the size of the earphone box in the thickness direction.

[0010] In some possible implementation manners of the first aspect, the bottom surface of the first cavity is curved, and the depth of the first cavity gradually decreases along a first direction, and the first direction is from the second cavity to the first cavity; and / or, the bottom surface of the third cavity is curved, and the depth of the third cavity gradually decreases along a second direction, and the second direction is from the fourth cavity to the third cavity.

[0011] The shape of the curved surface in each of the above embodiments can be determined according to the shape of the connecting arm placed in the accommodating cavity, so that at least part of the curved surface can be attached to the outer wall surface of the connecting arm after the earphone is placed in the accommodating cavity, to support the connecting arm.

[0012] In some possible implementation manners of the first aspect, a line between two points farthest apart in the width direction of the inner wall of the first accommodating cavity is referred to as a first line, and the first line is arranged at an angle to the width direction; and / or, a line between two points farthest apart in the width direction of the inner wall of the second accommodating cavity is referred to as a second line, and the second line is arranged at an angle to the width direction.

[0013] Since the first accommodating cavity and the second accommodating cavity are both of a structure of wide at one end and narrow at the other end in the width direction, when the first connecting line and the second connecting line are both parallel to the width direction, one of the first accommodating cavity and the second accommodating cavity protrudes in the thickness direction from the other, so that the combined structure of the first accommodating cavity and the second accommodating cavity has a larger size in the thickness direction, which can be 1.5 times or even larger than the size of the single accommodating cavity (the first accommodating cavity or the second accommodating cavity) in the thickness direction. By using any of the above three schemes and by reasonably setting the included angle between the corresponding connecting line and the width direction, the size of the protrusion of one of the first accommodating cavity and the second accommodating cavity in the thickness direction from the other can be reduced to a certain extent, so that the size of the combined structure of the first accommodating cavity and the second accommodating cavity in the thickness direction (i.e. the thickness of the combined structure) can be reduced to a certain extent, and thus the thickness of the earphone box can be reduced to a certain extent.

[0014] In some possible implementation manners of the first aspect, the first accommodating cavity and the second accommodating cavity partially overlap in orthographic projection on a projection plane perpendicular to the thickness direction. By using this scheme, the orthographic projections of the first accommodating cavity and the second accommodating cavity on the same projection plane perpendicular to the thickness direction have a certain overlapping area, so that at least part of the spacing portion of the first accommodating cavity and the second accommodating cavity in the thickness direction is located at the same height, which helps to reduce the size (i.e. the height) of the earphone box in the height direction, so that the volume of the earphone box can be reduced to a certain extent, facilitating the miniaturization design of the earphone box, so that the earphone box is convenient to carry.

[0015] In some possible implementation manners of the first aspect, the inner liner is further provided with a second spacing portion. In the width direction, at least part of the first accommodating cavity and at least part of the second accommodating cavity are spaced apart by the second spacing portion.

[0016] In this way, after the two earphones are placed into the earphone box, the connecting arm of at least one of the earphones is spaced apart from the first earphone body of the other earphone, so that the user can hold the connecting arm, thereby facilitating the user to take out the earphones from the earphone box and facilitating the user to put the earphones into the earphone box. In addition, the second spacing portion can also limit the first earphone body of the earphone to a certain extent, so as to limit the first earphone body of the earphone to a predetermined range (such as the second cavity) of the first accommodating cavity or a predetermined range (such as the fourth cavity) of the second accommodating cavity, and also can support the first earphone body of the earphone to a certain extent, so as to reduce the risk of the earphone falling after being placed into the earphone box, so that the earphone can be fixed at the corresponding position, which helps to stably place the earphone.

[0017] In some possible implementation manners of the first aspect, the at least one second spacing part is connected with the first spacing part. The connected first spacing part and second spacing part form a combined spacing part. At least part of the first accommodating cavity and the second accommodating cavity are spaced by the combined spacing part.

[0018] In this way, the first aspect can make the connection arms of the two earphones be spaced from the first earphone body of the other earphone after the two earphones are placed into the earphone box, so as to facilitate the user to hold the connection arms, thereby facilitating the user to take out the earphones from the earphone box and facilitating the user to place the earphones into the earphone box. The second aspect can make at least part of the first accommodating cavity and the second accommodating cavity be spaced, so that the two earphones have a smaller risk of interfering with each other after the two earphones are placed into the earphone box. The third aspect can make the combined spacing part play a certain limiting and supporting role on the earphones, so as to reduce the risk of the earphones being tilted and moved after the earphones are placed into the earphone box, and can make the earphones be better fixed at the corresponding positions, thereby facilitating stable placement of the earphones.

[0019] In some possible implementation manners of the first aspect, the first accommodating cavity has a lowest point in the height direction. The lowest point is a point in the inner wall of the first accommodating cavity that has the largest depth in the height direction. At least part of the side of the combined spacing part that is away from the lowest point in the height direction is a curved surface that is recessed toward the side where the lowest point is located. In this way, after the connection arms are placed into the first accommodating cavity or the second accommodating cavity, the connection arms will not interfere with the first accommodating cavity or the second accommodating cavity, and more parts of the connection arms can protrude from the combined spacing part, thereby facilitating the user to hold the connection arms, and thereby facilitating the taking out and placing operation of the earphones.

[0020] In some possible implementation manners of the first aspect, the mounting space is formed between the first shell and the inner liner. The inner liner is provided with a plurality of through structures. The first accommodating cavity is in communication with the mounting space through at least one through structure, and the second accommodating cavity is in communication with the mounting space through at least one through structure. The earphone box further comprises a spring sheet. The spring sheet is arranged in correspondence with the through structure. Part of the spring sheet is arranged in the mounting space, and the other part is inserted into the first accommodating cavity or the second accommodating cavity through the through structure.

[0021] The elastic sheet is a charging terminal for contacting the charging contact on the earphone. Compared with the charging needle, the charging terminal uses the elastic sheet. In the first aspect, when the earphone is placed in the earphone box after being moved or used daily, the salt in the sweat does not easily corrode the charging terminal, and the contact surface of the elastic sheet is flat, so the sweat stain can be easily cleaned (cotton swab wiping). In the second aspect, the elastic sheet contacts the charging contact of the earphone by plane pressure, so that even if the surface of the charging contact of the earphone has a slight sweat or water film, the elastic sheet can still maintain conduction with the charging contact (current passes through the liquid film to form a path), and the elastic sheet can tolerate a high degree of placement angle of the earphone, and can charge slightly offset. In the third aspect, the elastic sheet has high yield rate in mass production, and is convenient to repair and replace.

[0022] In some possible implementation manners of the first aspect, the elastic sheet includes a first sheet body and a second sheet body arranged at an included angle. The first sheet body is arranged in the mounting space, and at least part of the first sheet body is arranged in the height direction. The second sheet body is arranged at an included angle with the first sheet body, and at least part of the second sheet body is located in the first accommodating cavity or the second accommodating cavity. The distance between at least part of the second sheet body and the first sheet body decreases in the third direction. The third direction is from the opening of the first accommodating cavity to the bottom surface.

[0023] In the process of placing the earphone in the earphone box, the earphone is placed into the accommodating cavity from top to bottom. In this process, since the distance between the second sheet body and the first sheet body generally presents a gradually increasing trend from top to bottom, the protruding height of the second sheet body in the accommodating cavity gradually increases, and the pressure of the earphone on the second sheet body gradually increases, so that the earphone is finally pressed tightly with the elastic sheet after falling onto the bottom surface of the accommodating cavity, and the earphone can maintain the pressed state with the elastic sheet under the action of gravity. This helps the charging contact on the earphone to stably contact the elastic sheet, so that the earphone can be stably charged.

[0024] In some possible implementation manners of the first aspect, the inner liner has a first surface and a second surface arranged opposite to each other. The first surface surrounds the first accommodating cavity. The second surface is provided with a limiting structure. The limiting structure and the second surface form a mounting channel. At least part of the elastic sheet is arranged in the mounting channel and abuts against the limiting structure.

[0025] The limiting structure can be a plate body, or a U-shaped structure, a C-shaped structure, or other shapes, which can be determined according to the use requirement. The limiting structure can be integrally formed with the inner liner, or connected with the inner liner in a separate manner (such as insertion, clamping, etc.). The limiting structure can make the movement range of the elastic sheet in the direction perpendicular to the length direction of the mounting channel only within the width range of the mounting channel, so that the protruding length of the elastic sheet from the inner wall of the first accommodating cavity is always within a preset range, and the first earphone body can stably contact the elastic sheet after being placed in the first cavity, so that the charging of the earphone can be stably performed.

[0026] In some possible implementation manners of the first aspect, the limiting structure has a limiting surface. The elastic sheet has a limiting portion. The limiting portion is capable of being in contact with the limiting surface to limit the length of the elastic sheet inserted into the mounting channel. Through the cooperation of the limiting surface and the limiting portion in the elastic sheet, the length of the portion of the elastic sheet inserted into the mounting channel can be limited, so that the relative positions of the elastic sheet, the mounting channel and the first cavity in different products are the same, so that the stability of the earphone case is high when the earphone case is mass-produced, and the charging contact on the earphone can correspond to the position of the convex portion on the elastic sheet after the earphone is placed into the earphone case, and stable contact with the elastic sheet is achieved.

[0027] In some possible implementation manners of the first aspect, the side wall of the first accommodating cavity comprises a first curved surface. The first curved surface has a plurality of first corner regions. At least part of the first corner regions are arranged away from the second accommodating cavity. The through structure is arranged in at least one of the first corner regions away from the second accommodating cavity; and / or, the side wall of the second accommodating cavity comprises a second curved surface, the second curved surface has a plurality of second corner regions, at least part of the second corner regions are arranged away from the second accommodating cavity, and the through structure is arranged in at least one of the second corner regions away from the second accommodating cavity. Since the radius of the curved surface corresponding to the corner region is generally smaller than the radius of the curved surface corresponding to other regions. In this way, the spacing between the curved surface and the inner wall or the outer wall of the first shell is larger at the corner region, and the thickness of the first shell is not easily increased due to the arrangement of the elastic sheet, which is helpful for reducing the volume of the earphone case, and the appearance of the first part is also beautiful.

[0028] In some possible implementation manners of the first aspect, at least part of the inner wall of the first accommodating cavity is symmetrical relative to the first symmetry plane, at least part of the inner wall of the second accommodating cavity is symmetrical relative to the second symmetry plane, and the first symmetry plane and the second symmetry plane are parallel to each other. In this way, at least part of the inner wall of the first accommodating cavity is a symmetrical structure, and the pre-set symmetry planes corresponding to the first accommodating cavity and the second accommodating cavity are parallel to each other, which is beneficial to the design of the first accommodating cavity and the second accommodating cavity, and the structure of the first accommodating cavity and the second accommodating cavity is compact, the spacing space between the two is small, the space occupied is small, and the miniaturization design of the earphone case is facilitated.

[0029] In some possible implementation manners of the first aspect, the first accommodating cavity corresponds to two through structures, the two through structures are arranged on the two sides of the first symmetry plane in the first accommodating cavity, and the elastic sheet is arranged in one-to-one correspondence with the through structures; and / or, the second accommodating cavity corresponds to two through structures, the two through structures are arranged on the two sides of the second symmetry plane in the second accommodating cavity, and the elastic sheet is arranged in one-to-one correspondence with the through structures.

[0030] In this way, compared with two through structures corresponding to the first cavity, the two through structures are arranged adjacent to each other, so that the distance between the two through structures is large, thereby the distance between the two elastic sheets corresponding to the same first cavity is large, and the risk of short circuit of the two elastic sheets and the two charging contacts of the earphone can be reduced to a certain extent.

[0031] In some possible implementation manners of the first aspect, the first part further comprises a magnet module arranged in the mounting space. The magnet module is arranged between the two through structures. In this way, after the earphone is placed into the first accommodating cavity, the magnet module can attract and adsorb the relative position of the earphone and the inner liner through magnetic force, so as to reduce the risk of movement of the earphone under external force after the earphone is placed into the first accommodating cavity, and the charging contacts on the earphone can be in stable contact with the elastic sheet at all times. Moreover, the arrangement of the magnet module does not occupy the mounting space of the elastic sheet. The magnet module is in one-to-one correspondence with the first accommodating cavity. One or more magnetic members, such as one or more permanent magnets, one or more electromagnets, etc., can be included in the same magnet module, which can be determined according to the use requirement.

[0032] In some possible implementation manners of the first aspect, the earphone box further comprises a second part. The second part is provided with a third accommodating cavity. The second part is capable of moving relative to the first part between a first position and a second position. In the first position, the second part is buckled with the first part, and the third accommodating cavity is in communication with the first accommodating cavity and the second accommodating cavity, respectively. In the second position, the second part exposes the first accommodating cavity and the second accommodating cavity. An inner wall of the third accommodating cavity is provided with a positioning structure. The positioning structure is used to cooperate with the inner wall of the first accommodating cavity and the inner wall of the second accommodating cavity to limit the position of the earphone.

[0033] The second part can play a certain protective role on the earphone, and reduce the risk of damage of the earphone after being placed into the earphone box. The positioning structure can be an elastic structure, a clamping structure, a plug-in structure, etc., and can limit the relative position of the second earphone body and the earphone box through abutment, friction contact, plug-in, etc., thereby reducing the risk of shaking of the earphone in the earphone box after being placed into the earphone box.

[0034] In some possible implementation manners of the first aspect, the positioning structure comprises an elastic member. The elastic member covers at least part of the projection area of the first accommodating cavity in the third accommodating cavity, and / or the elastic member covers at least part of the projection area of the second accommodating cavity in the third accommodating cavity. In this way, at least part of the elastic member can be in contact with the second earphone body when the first part and the second part are buckled, so as to apply a pressure to the second earphone body towards the first earphone body, thereby the elastic member and the inner liner can cooperate with each other to clamp the earphone, so as to reduce the risk of shaking of the earphone in the earphone box.

[0035] In some possible implementations of the first aspect, the second portion includes a rigid member. The third accommodating cavity is provided in the rigid member, i.e., the third accommodating cavity is provided on the rigid member. The elastic member covers the outer surface of the rigid member. This allows the elastic member to cover all surfaces of the rigid member corresponding to the second earphone body, thereby reducing the risk of contact between the rigid member and the second earphone body and the risk of damage to the second earphone body.

[0036] In some possible implementations of the first aspect, the elastic member is provided with a first plug-in portion. The rigid member is provided with a second plug-in portion. The elastic member is plugged into and matched with the rigid member through the second plug-in portion and the first plug-in portion. The first plug-in portion and the second plug-in portion are two components that are plugged into and matched with each other. If the first plug-in portion is a convex structure, the second plug-in structure may be a concave structure. If the first plug-in portion is a concave structure, the second plug-in portion may be a convex structure. Specifically, when the first plug-in portion and the second plug-in portion are plugged into each other, the two may be interference fit, clearance fit, or frictional contact, which may be determined according to the needs of use. The provision of the second plug-in portion and the first plug-in portion realizes a detachable connection between the rigid member and the elastic member, making it difficult for the elastic member to be separated from the rigid member and facilitating the replacement and maintenance of the elastic member.

[0037] In a second aspect, an embodiment of the present application provides an earphone assembly. The earphone assembly includes an earphone and an earphone box provided in any of the above embodiments. The earphone is disposed in the earphone box.

[0038] The beneficial effects of the second aspect can be found in the relevant description of the first aspect above, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] As shown in Figure 1 As shown in Figure 2As shown, the earphone assembly 100 comprises an earphone 10 and an earphone box 20. The earphone 10 is a clip-on wireless earphone. According to the features of "wearing mode" and "acoustic structure", the earphone 10 can be classified into three categories: in-ear, semi-open and open. For the convenience of description, the following description takes the earphone 10 as an open earphone as an example.

[0059] Figure 3 For Figure 1 As shown in the exploded structural schematic diagram of the earphone assembly.

[0060] As Figure 3 As shown, the earphone 10 generally comprises a first earphone body 11, a connecting arm 12 and a second earphone body 13 connected in sequence. The first earphone body 11 is generally provided with a battery and a charging contact electrically connected with the battery, etc. The second earphone body 13 is used for sound production, and is generally provided with a microphone, a loudspeaker, etc. In other embodiments, the loudspeaker and the microphone can also be provided in the first earphone body 11, or the first earphone body 11 and the second earphone body 13 are both provided with the microphone and the loudspeaker, or other setting modes are adopted.

[0061] When the user uses the earphone 10, the first earphone body 11, the connecting arm 12 and the second earphone body 13 jointly hold the pinna of the user. Specifically, the second earphone body 13 can be clamped in the concha cavity of the user and does not enter the ear canal of the user. The first earphone body 11 is located outside the ear of the user and away from the side of the second earphone body 13. The connecting arm 12 is buckled on the side of the outer edge of the ear of the user and extends from the concha cavity to the position behind the ear.

[0062] Because when worn, the first earphone body 11 is located outside the ear and the second earphone body 13 is located inside the ear, more electronic components can be arranged in the first earphone body 11 than in the second earphone body 13. In this way, the volume of the first earphone body 11 is generally greater than or equal to the volume of the second earphone body 13, and the weight of the first earphone body 11 is greater than or equal to the weight of the second earphone body 13.

[0063] In addition, in order to balance the stability and comfort of wearing, the connecting arm 12 generally has a certain elasticity and rigidity. For example, the connecting arm 12 can include a metal piece and an elastic piece wrapped outside the metal piece, and can also include other structural pieces such as a wire electrically connecting the first earphone body 11 and the second earphone body 13 according to the needs of use, which can be determined according to the needs of use. The elasticity of the connecting arm 12 can make the connecting arm 12 adapt to the shapes of the pinnae of different users, and reduce the compression pain of the user when wearing the earphone 10. The rigidity of the connecting arm 12 can provide sufficient support force, so that the earphone 10 is not easy to move or fall off during movement (such as keeping stable when running), and can also make the center of gravity of the second earphone body 13, the center of gravity of the first earphone body 11 and the center of gravity of the connecting arm 12 always be on the same straight line, or approximately on the same straight line, so that the center of gravity of the second earphone body 13 can be located directly above the center of gravity of the first earphone body 11 when the earphone 10 is placed vertically. The above-mentioned vertical placement refers to that the first earphone body 11 is in contact with the supporting surface (such as a table top, ground, etc.), and the first earphone body 11, the connecting arm 12 and the second earphone body 13 are arranged in turn in the opposite direction of the gravity direction.

[0064] In the same earphone assembly 100, the earphone 10 generally has multiple, such as two. For the convenience of description, the following will be described by taking the example of the same earphone assembly 100 having two earphones 10. The two earphones 10 are respectively referred to as the first earphone 10a and the second earphone 10b, wherein the first earphone 10a is the earphone 10 located on the left side in the Figure 3 , and the second earphone 10b is the earphone 10 located on the right side in the Figure 3 . The shapes and structures of the first earphone 10a and the second earphone 10b can be the same or different, which can be determined according to the needs of use.

[0065] The earphone box 20 is used to provide a containing space for the earphone 10, and can contain two earphones 10 at the same time and charge the two earphones 10.

[0066] As shown in Figure 2 and Figure 3 , the earphone box 20 generally includes a first part 21 and a second part 22. In special cases, the earphone box 20 can only include the first part 21, which can be determined according to the needs of use. The first part 21 can be a hollow structure with an open end or a side opening, used to contain at least part of the earphone 10 and charge the earphone 10. The above-mentioned open end refers to that the first part 21 is provided with an opening at one end in the height direction Z. The side opening refers to that one of the large faces (the faces formed by the long side and the wide side) of the first part 21 is provided with an opening. The cross-sectional area of the side opening is generally larger than that of the cross-section of the open end.

[0067] The second part 22 can be a plate structure, a hollow structure with an open side, or the like. The second part 22 can cooperatively define a receiving space with the first part 21 for receiving the earphone 10.

[0068] As shown in the example, Figure 2 In some embodiments, the first part 21 and the second part 22 can both be hollow structures with an open side, and the open side of the second part 22 covers the open side of the first part 21. In other embodiments, the first part 21 can be a hollow structure with an open end, and the second part 22 can be a plate structure, and the second part 22 covers the open end of the first part 21 to cooperatively define a receiving space with the first part 21. Of course, the first part 21 and the second part 22 can also adopt other structures as long as they can cooperatively define a receiving space for receiving the earphone 10. The earphone case 20 formed by the first part 21 and the second part 22 can have various shapes, such as a cylinder, a cuboid, or the like.

[0069] The second part 22 described above can be detachably coupled to the first part 21, or rotatably coupled to the first part 21, or slidably coupled to the first part 21, or coupled to the first part 21 in other manners, which can be determined according to the needs. Figure 2 As shown in the example,

[0070] The earphone case 20 includes the first part 21, the second part 22, and a hinge structure 23. A portion of the hinge structure 23 is coupled to the first part 21, and another portion of the hinge structure 23 is coupled to the second part 22. The first part 21 and the second part 22 are relatively rotatable through the hinge structure 23, so that the earphone case 20 can be switched between a closed state and an open state. When the earphone case 20 is in the closed state, a receiving space for receiving the earphone 10 is blocked. When the earphone case 20 is in the open state, the receiving space is exposed, and the user can place the earphone 10 in the receiving space or take the earphone 10 out of the receiving space.

[0071] The first part 21 includes a first shell 211 and an inner liner 212. The first shell 211 and the inner liner 212 are both hollow structures with an open end or an open side, and the open directions of the two are consistent. The open directions of the two determine the open direction of the first part 21.

[0072] For the convenience of description, the opening direction of the first part 21 (i.e. the direction from the first part 21 to the second part 22) is referred to as the height direction Z of the earphone box 20, the axial direction of the rotating shaft structure 23 is referred to as the width direction X1 of the earphone box 20, and the direction perpendicular to the height direction Z and the width direction X1 is referred to as the thickness direction Y of the earphone box 20.

[0073] In combination with Figure 2 and Figure 3 , most of the inner liner 212 is arranged in the first shell 211, and a small part of the inner liner 212 protrudes out of the first shell 211. In other embodiments, the inner liner 212 can be completely arranged in the first shell 211. The inner liner 212 has a front surface and a back surface arranged opposite to each other in the height direction Z of the earphone box 20. The front surface of the inner liner 212 is formed with a first accommodating cavity 213a and a second accommodating cavity 213b. The first accommodating cavity 213a is used to accommodate at least part of the first earphone 10a, and the second accommodating cavity 213b is used to accommodate at least part of the second earphone 10b. At least part of the back surface of the inner liner 212 is arranged spaced apart from the inner wall of the first shell 211 and forms an installation space 214 with the inner wall of the first shell 211.

[0074] The first part 21 can further include a charging module 215, a battery module 216, a mainboard 217, a loudspeaker 218, a magnet module 219, etc. The charging module 215 can include a first module 215a, a second module 215b, a charging coil module 215c, etc. The battery module 216, the charging coil module 215c, the mainboard 217, an antenna, the loudspeaker 218, the magnet module 219, etc. are arranged in the installation space 214 and are fixed in position by a fixing member.

[0075] The first module 215a corresponds to the first accommodating cavity 213a accommodating the first earphone 10a and is used to charge the first earphone 10a. Part of the first module 215a is arranged in the installation space 214, and the other part extends into the first accommodating cavity 213a through the side wall of the inner liner 212. The second module 215b corresponds to the second accommodating cavity 213b accommodating the second earphone 10b and is used to charge the second earphone 10b. Part of the second module 215b is arranged in the installation space 214, and the other part extends into the second accommodating cavity 213b through the side wall of the inner liner 212.

[0076] In the related art, the first accommodating cavity 213a and the second accommodating cavity 213b are arranged in the width direction X1 of the earphone box 20. The first accommodating cavity 213a, the second accommodating cavity 213b and the interval region therebetween can be regarded as a combined structure. The maximum dimension of the combined structure in the width direction X1 of the earphone box 20 is greater than the sum of the dimensions of the first accommodating cavity 213a and the second accommodating cavity 213b in the width direction X1 of the earphone box 20. That is, the maximum width of the combined structure is greater than the sum of the widths of the first accommodating cavity 213a and the second accommodating cavity 213b. In order to reduce the volume of the earphone box 20, an embodiment of the present application provides an earphone box 20.

[0077] Figure 4 The use state diagram of the first part of the earphone and the earphone box in the earphone assembly provided by an embodiment of the present application.

[0078] As shown in Figure 4 The earphone box 20 at least includes a first part 21. The first part 21 has a width direction, a thickness direction and a height direction. The width direction of the first part 21 is consistent with the width direction of the earphone box 20, both being the X1 direction in the figure; the thickness direction of the first part 21 is consistent with the thickness direction of the earphone box 20, both being the Y direction in the figure; and the height direction of the first part 21 is consistent with the height direction of the earphone box 20, both being the Z direction in the figure. Generally, the dimension (i.e. width) of the first part 21 in the width direction X1 is greater than the dimension (i.e. thickness) of the first part 21 in the thickness direction Y. The first part 21 includes a first shell 211 and an inner lining 212. At least part of the inner lining 212 is arranged in the first shell 211. That is, according to the use requirement, the inner lining 212 can be located in the first shell 211 entirely, or part of the inner lining 212 is located in the first shell 211 and the other part protrudes from the first shell 211.

[0079] The inner liner 212 is provided with a first accommodating cavity 213a and a second accommodating cavity 213b. As aforementioned, the first accommodating cavity 213a is used for accommodating at least part of the first earphone 10a, and the second accommodating cavity 213b is used for accommodating at least part of the second earphone 10b. The shape and structure of the first accommodating cavity 213a and the second accommodating cavity 213b can be determined according to the placement requirement of the earphones. For example, the earphones 10 need to be placed in the earphone box 20 in a vertical placement manner, in which case the first accommodating cavity 213a is used for accommodating part of the first earphone body 11 and part of the connecting arm 12 of the first earphone 10a, and the second earphone body 13 of the first earphone 10a protrudes out of the first part 21. The shape and structure of the first accommodating cavity 213a can be designed according to the shape and structure of the first earphone body 11 and the connecting arm 12 of the first earphone 10a. For example, the earphones 10 need to be placed in the earphone box 20 in a horizontal placement manner, in which case the first accommodating cavity 213a is used for accommodating part of the first earphone body 11, part of the connecting arm 12, and part of the second earphone body 13 of the first earphone 10a. The shape and structure of the first accommodating cavity 213a can be designed according to the shape and structure of the first earphone body 11, the connecting arm 12, and the second earphone body 13 of the first earphone 10a. It can be understood that when the earphones 10 need to be placed in other manners, the first accommodating cavity 213a and the second accommodating cavity 213b can also be arranged in other manners. For example, the first accommodating cavity 213a and the second accommodating cavity 213b can both adopt a cubic structure, or both adopt an irregular groove structure.

[0080] According to the use requirement, the shape and structure of the first accommodating cavity 213a and the second accommodating cavity 213b can be completely the same or different. For example, when the shape and structure of the first earphone 10a and the second earphone 10b are completely the same, the shape and structure of the first accommodating cavity 213a and the second accommodating cavity 213b can also be completely the same. It can be understood that due to the existence of processing errors, even if the shape and structure of the first accommodating cavity 213a and the second accommodating cavity 213b are completely the same in design, there will still be slight differences between the two after the finished product is made. For example, when the shape and structure of the first earphone 10a and the second earphone 10b are different, the shape and structure of the first accommodating cavity 213a and the second accommodating cavity 213b can also be different.

[0081] Figure 5 For Figure 4 the first part of the inner liner is shown in the perspective view.

[0082] As Figure 5 shown, in addition to the first accommodating cavity 213a and the second accommodating cavity 213b described above, the inner liner 212 is also provided with a first spacing part 2121. In the thickness direction Y, part of the first accommodating cavity 213a and part of the second accommodating cavity 213b are arranged in a spaced manner by the first spacing part 2121.

[0083] In this embodiment, the first spacer 2121 can be a part of the lining 212, which is protruding compared to the bottom surface of the first accommodating cavity 213a and the bottom surface of the second accommodating cavity 213b. Particularly, at least parts of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart in the thickness direction Y. The first accommodating cavity 213a, the second accommodating cavity 213b and the spaced area therebetween form a first combined area, and the lining 212 at least includes a main body 2124 and a first spacer 2121. The main body 2124 is arranged around the first combined area. The first spacer 2121 is arranged in the spaced area between the first accommodating cavity 213a and the second accommodating cavity 213b, and at least the bottom of the first spacer 2121 is connected to the main body 2124.

[0084] Figure 6 A schematic top view of the first part of the earphone case provided in one embodiment of the present application; Figure 7 This is a schematic top view of the first part of the earphone box provided in another embodiment of the present application.

[0085] The shape, size and location of the first spacer 2121 can be determined according to the needs of use. Figure 6 As shown, the first spacer 2121 can be set longer to completely separate the first and second accommodating cavities 213a, 213b in the thickness direction. The first spacer 2121 can also be set shorter to only separate a portion of the first and second accommodating cavities 213a, 213b in the thickness direction. When the first spacer 2121 is set shorter, the first spacer 2121 can be set at the end (one end or both ends) of the thickness-wise spacing between the first and second accommodating cavities 213a, 213b. In this case, the first spacer 2121 can be connected to both the sidewalls and the bottom of the main body 2124. The first spacer 2121 can also be set in the center of the thickness-wise spacing between the first and second accommodating cavities 213a, 213b to separate the middle portion of the thickness-wise spacing between the first and second accommodating cavities 213a, 213b.

[0086] In this embodiment, only the first spacer 2121 may be provided between the first accommodation cavity 213a and the second accommodation cavity 213b. Figure 7 As shown; can also be Figure 6 As shown, in addition to the first spacer 2121, other spacers are provided, and the specific spacers can be determined according to usage requirements.

[0087] In addition, in this embodiment, the first spacing portion 2121 can be composed of one or more components according to aesthetics, use requirements, etc. When the first spacing portion 2121 includes multiple components, the multiple components can be spaced apart along the direction of the spacing portion of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction, or can be sequentially arranged and connected, and the shape, structure, material, etc. of each component can be the same or different, which can be determined according to design requirements.

[0088] For ease of description, the setting mode and use mode of the earphone box 20 provided in the embodiments of the present application are described below by taking the vertical placement of the earphone 10 as an example.

[0089] In use, the first earphone body 11 and the connecting portion of the connecting arm 12 and the first earphone body 11 of the first earphone 10a are placed in the first accommodating cavity 213a, and the first earphone body 11 and the connecting portion of the connecting arm 12 and the first earphone body 11 of the second earphone 10b are placed in the second accommodating cavity 213b. After being placed, the first earphone 10a and the second earphone 10b are vertically placed, and a part of each is arranged to cross each other. Since at least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart, the first earphone 10a and the second earphone 10b are generally spaced apart after being placed in the earphone box 20, and do not contact each other.

[0090] It can be understood that the larger the volume of the first spacing portion 2121, the smaller the probability of mutual contact of the first earphone 10a and the second earphone 10b after being placed in the earphone box 20, and the smaller the risk of mutual interference between the two earphones 10.

[0091] By adopting the scheme provided in this embodiment, at least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart in the thickness direction Y and separated by the first spacing portion 2121, so that the first earphone 10a and the second earphone 10b can be placed in the middle region of the earphone box 20. The combination structure formed by the first accommodating cavity 213a, the second accommodating cavity 213b and the spacing space therebetween has a maximum size in the width direction X1 which is smaller than the sum of the sizes of the first accommodating cavity 213a and the second accommodating cavity 213b in the width direction X1, thereby reducing the volume of the earphone box 20 to a certain extent, facilitating the miniaturization design of the earphone box 20, and making the earphone box 20 convenient to carry.

[0092] Among them, the setting of the first spacer 2121 can, on the one hand, separate at least part of the spacing portion of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction, so that after the earphone 10 is placed in, the first earphone 10a and the second earphone 10b can be at least partially separated, so that there is a certain distance between the two earphones 10, and they will not affect each other when taking and placing; on the other hand, the setting of the first spacer 2121 can also play a certain supporting role for the earphone 10, reducing the risk of the earphone 10 tipping over after being placed in the earphone box 20, and can make the earphone 10 better fixed in the corresponding position, which helps to stably place the earphone 10.

[0093] like Figure 4 As shown, in some embodiments, the first accommodating cavity 213a is used to accommodate a portion of the first earphone body 11 and a portion of the connecting arm 12 of the first earphone 10a. The second accommodating cavity 213b is used to accommodate a portion of the first earphone body 11 and a portion of the connecting arm 12 of the second earphone 10b. That is, the first earphone 10a and the second earphone 10b are placed in the earphone box 20 in a vertical manner, and the second earphone bodies 13 of the two earphones 10 are both located outside the first shell 211. In this embodiment, the maximum dimension (i.e., width) of the combined structure of the first accommodating cavity 213a and the second accommodating cavity 213b in the width direction X1 can be greater than the maximum dimension (i.e., thickness) of the above-mentioned combined structure in the thickness direction Y, and can also be greater than the maximum dimension (i.e., height or depth) of the above-mentioned combined structure in the height direction Z. In this way, compared with the two earphone bodies (the first earphone body 11 and the second earphone body 13) of the same earphone 10 being arranged in the accommodating cavity (the first accommodating cavity 213a or the second accommodating cavity 213b) of the earphone box 20, the size of the earphone box 20 in the width direction X1 (that is, the width of the earphone box 20) can be further reduced, thereby reducing the volume of the earphone box 20 to a certain extent, facilitating the miniaturized design of the earphone box 20, and making the earphone box 20 easy to carry.

[0094] On the basis of the above embodiment, in order to further reduce the size of the earphone box 20 in the thickness direction Y, as shown in FIG. Figure 6 As shown, in some embodiments, the portion of the first accommodating cavity 213a separated from the second accommodating cavity 213b by the first partition 2121 is referred to as the first cavity. The portion of the first accommodating cavity 213a excluding the first cavity is referred to as the second cavity. The portion of the second accommodating cavity 213b separated from the first accommodating cavity 213a by the first partition 2121 is referred to as the third cavity. The portion of the second accommodating cavity 213b excluding the third cavity is referred to as the fourth cavity.

[0095] The maximum thickness a1 of the first cavity is less than the maximum thickness a2 of the second cavity, and the maximum thickness a3 of the third cavity is less than the maximum thickness a4 of the fourth cavity. In other embodiments, only the maximum thickness of the first cavity can be less than the maximum thickness of the second cavity, or only the maximum thickness of the third cavity can be less than the maximum thickness of the fourth cavity, which can be determined according to the needs of use.

[0096] The first accommodating cavity 213a and the second accommodating cavity 213b in the embodiment are both largest in the size in the width direction X1. That is, the size (width) of the first accommodating cavity 213a in the width direction X1 is greater than the size (depth) of the first accommodating cavity 213a in the height direction Z and greater than the size (thickness) of the first accommodating cavity 213a in the thickness direction Y.

[0097] The first accommodating cavity 213a and the second accommodating cavity 213b are both structures with one end wide and the other end narrow in the width direction X1, which can be a gourd shape, a trapezoidal shape, etc., and can be determined according to the placement needs of the earphone 10. In the embodiment, the narrow end of the first accommodating cavity 213a and the narrow end of the second accommodating cavity 213b are arranged to intersect each other.

[0098] The first cavity and the second cavity are both a part of the first accommodating cavity 213a, and the third cavity and the fourth cavity are both a part of the second accommodating cavity 213b.

[0099] The part of the first accommodating cavity 213a spaced from the second accommodating cavity 213b by the first spacing part 2121 is referred to as the first cavity, and the part of the first accommodating cavity 213a other than the first cavity is referred to as the second cavity, which means that, in the projection plane perpendicular to the thickness direction Y, the part of the first accommodating cavity 213a whose orthogonal projection at least partially coincides with the orthogonal projection of the first spacing part 2121 is the first cavity, and the part of the first accommodating cavity 213a whose orthogonal projection is outside the orthogonal projection of the first spacing part 2121 is the second cavity. The part of the second accommodating cavity 213b spaced from the first accommodating cavity 213a by the first spacing part 2121 is referred to as the third cavity, and the part of the second accommodating cavity 213b other than the third cavity is referred to as the fourth cavity, which means that, in the projection plane perpendicular to the thickness direction Y, the part of the second accommodating cavity 213b whose orthogonal projection at least partially coincides with the orthogonal projection of the first spacing part 2121 is the third cavity, and the part of the second accommodating cavity 213b whose orthogonal projection is outside the orthogonal projection of the first spacing part 2121 is the fourth cavity.

[0100] For ease of understanding, Figure 6Two dashed lines L1 and L2 are drawn in the first interval 2121 in the width direction X1. The boundary line between the first cavity and the second cavity is the extension of the dashed line L2. The part of the first accommodating cavity 213a located on the left side of the extension of the dashed line L2 is the second cavity, and the part located on the right side of the extension of the dashed line L2 is the first cavity. The boundary line between the third cavity and the fourth cavity is the extension of the dashed line L1. The part of the second accommodating cavity 213b located on the left side of the extension of the dashed line L1 is the third cavity, and the part located on the right side of the extension of the dashed line L1 is the fourth cavity.

[0101] It can be understood that the above-mentioned dashed lines L1 and L2 are auxiliary lines drawn for the convenience of understanding, and are not structural lines of the inner liner 212.

[0102] It should be noted that when the first interval 2121 includes multiple components and the multiple components are arranged at intervals, when the ranges of the first cavity and the third cavity are determined by the first interval 2121, the first interval 2121 should be regarded as being composed of the multiple components and the cavities between the components.

[0103] Since the first cavity, the second cavity, the third cavity and the fourth cavity can all be irregular shapes. The above-mentioned maximum thickness refers to the maximum dimension of the corresponding part in the thickness direction Y. For the convenience of understanding, the maximum thickness of the first cavity will be taken as an example for description. The thicknesses of different regions of the first cavity can be different, such as the thickness of position 1 is b1, the thickness of position 2 is b2, the thickness of position 3 is b3, …, and the thickness of position n is bn, where bn>b2>b1>…>b3, and the maximum thickness a1 of the first cavity is bn, that is, a1=bn.

[0104] It should be noted that the thicknesses and maximum thicknesses of the cavities are all the dimensions of the cavities (hollow parts) in the thickness direction Y of the earphone box 20.

[0105] The thicknesses of the first cavity and the third cavity in the embodiment are small, and can be used to accommodate at least part of the connecting arm 12 of the earphone 10. The thicknesses of the second cavity and the fourth cavity are large, and can be used to accommodate at least part of the first earphone body 11 of the earphone 10. In this way, on the one hand, the earphone 10 can be placed in a vertical placement manner in the earphone box 20, so that the size of the earphone box 20 in the width direction X1 is small; on the other hand, the thicknesses of the first cavity and the third cavity located in the middle region of the earphone box are small, and the thicknesses of the second cavity and the fourth cavity located at the end of the earphone box are large, so that the connecting arms 12 of the two earphones 10 can be arranged in a crossing manner (as shown in FIG. 6B), so that the size of the intersection region of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y does not need to be set too large, and thus the size of the earphone box 20 in the thickness direction Y can be reduced to a certain extent. Figure 5

[0106] As shown in FIG. 6B, the first cavity and the third cavity are arranged in the middle region of the earphone box 20, and the second cavity and the fourth cavity are arranged at the end of the earphone box 20. The connecting arms 12 of the two earphones 10 are arranged in a crossing manner. Figure 4 ​and Figure 5 As shown, based on the above embodiment, in order to ensure stable support after the connecting arm 12 is placed in the earphone box 20, in some embodiments, the bottom surface of the first cavity is a curved surface, and the depth of the first cavity gradually decreases along the first direction X2, and the first direction X2 is from the second cavity to the first cavity. The bottom surface of the third cavity is a curved surface, and the depth of the third cavity gradually decreases along the second direction X3, and the second direction X3 is from the fourth cavity to the third cavity. In other embodiments, only the bottom surface of the first cavity may be provided with the above-mentioned curved surface, or only the bottom surface of the third cavity may be provided with the above-mentioned curved surface.

[0107] It can be understood that when the above-mentioned curved surface is set only on the bottom surface of the first cavity, only the connecting arm 12 of the first earphone 10a can achieve stable support after being placed in the earphone box 20; when the above-mentioned curved surface is set only on the bottom surface of the third cavity, only the connecting arm 12 of the second earphone 10b can achieve stable support after being placed in the earphone box 20; when the above-mentioned curved surface is set on the bottom surface of the first cavity and the above-mentioned curved surface is set on the bottom surface of the third cavity, both the connecting arm 12 of the first earphone 10a and the connecting arm 12 of the second earphone 10b can achieve stable support after being placed in the earphone box 20.

[0108] The shape of the curved surface in the above embodiments can be determined according to the shape of the connecting arm 12 placed in the accommodating cavity, so that after the earphone 10 is placed in the accommodating cavity, at least part of the curved surface can fit into the outer wall surface of the connecting arm 12 to provide support for the connecting arm 12.

[0109] like Figure 6 As shown, in order to further reduce the size of the earphone box 20 in the thickness direction Y, multiple configurations can be used:

[0110] In the first method, the line connecting the two points on the inner wall of the first accommodating cavity 213a that are the most distant in the width direction X1 is designated as the first line L3, and the first line L3 is disposed at an angle to the width direction X1. The line connecting the two points on the inner wall of the second accommodating cavity 213b that are the most distant in the width direction X1 is designated as the second line L4, and the second line L4 is disposed at an angle to the width direction X1. In this case, the first line L3 and the second line L4 can be parallel or at an angle, depending on the specific needs.

[0111] The second type is that the first connecting line L3 is arranged at an angle to the width direction X1. In this case, the second connecting line L4 can be arranged at an angle to the width direction X1 or can be arranged parallel to the width direction X1.

[0112] The third type is that the second connecting line L4 is arranged at an angle to the width direction X1. In this case, the first connecting line L3 can be arranged at an angle to the width direction X1 or can be arranged parallel to the width direction X1.

[0113] In the above-mentioned cases, the included angle is a non-zero included angle, such as 10°, 20°, 50°, 60°, 110°, 120°, 150°, etc., and other angles may also be used, depending on the specific needs of use.

[0114] It should be noted that the first connecting line L3 and the second connecting line L4 in the figure are auxiliary lines for facilitating understanding of the positions of the first connecting line and the second connecting line, and are not structural lines of the lining 212 .

[0115] Because the first accommodating cavity 213a and the second accommodating cavity 213b are both wider at one end and narrower at the other end in the width direction X1, when the first connecting line L3 and the second connecting line L4 are both parallel to the width direction X1, one of the first accommodating cavity 213a and the second accommodating cavity 213b will protrude from the other in the thickness direction Y. This results in a larger dimension of the combined structure formed by the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y, which can be 1.5 times or even larger than the dimension of a single accommodating cavity (the first accommodating cavity 213a or the second accommodating cavity 213b) in the thickness direction Y. By employing any of the three aforementioned solutions, by appropriately setting the angle between the corresponding connecting line and the width direction X1, the extent of the protrusion of one accommodating cavity from the other in the thickness direction Y can be reduced to a certain extent, thereby reducing the dimension of the combined structure formed by the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y (i.e., the thickness of the combined structure), thereby reducing the thickness of the earphone case 20 to a certain extent. It can be understood that, in the case where the first situation mentioned above is adopted and the first line L3 and the second line L4 are parallel, Figure 6 As shown, by reasonably setting the angle between the first connecting line L3 and the width direction X1, the size of the combined structure of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y can be equal to the size of the first accommodating cavity 213a or the second accommodating cavity 213b in the thickness direction Y.

[0116] In order to reduce the risk of interference between the two earphones 10 when the two earphones 10 are placed in the earphone box 20 or taken out of the earphone box 20, as shown in FIG. Figure 6 As shown, in some embodiments, the orthographic projection of the first accommodating cavity 213a and the orthographic projection of the second accommodating cavity 213b partially overlap on the projection plane perpendicular to the thickness direction Y. That is, on the projection plane perpendicular to the thickness direction Y, a portion of the orthographic projection of the first accommodating cavity 213a overlaps with a portion of the orthographic projection of the second accommodating cavity 213b, another portion of the orthographic projection of the first accommodating cavity 213a is located outside the orthographic projection of the second accommodating cavity 213b, and another portion of the orthographic projection of the second accommodating cavity 213b is located outside the orthographic projection of the first accommodating cavity 213a.

[0117] In the embodiment, at least part of the interval part of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y is located at the same height.

[0118] By using the scheme provided in the embodiment, the first accommodating cavity 213a and the second accommodating cavity 213b have a certain overlapping area in the orthographic projection on the same projection plane perpendicular to the thickness direction Y, so that at least part of the interval part of the first accommodating cavity 213a and the second accommodating cavity 213b in the thickness direction Y is located at the same height, compared with the first cavity of the first accommodating cavity 213a and the first cavity of the second accommodating cavity 213b being staggered in the height direction Z, which helps to reduce the size (i.e. height) of the earphone box 20 in the height direction Z, so that the volume of the earphone box 20 can be reduced to a certain extent, facilitating the miniaturization design of the earphone box 20, so that the earphone box 20 is convenient to carry.

[0119] In order to achieve the above effect, in addition to setting the first interval part 2121 between the first accommodating cavity 213a and the second accommodating cavity 213b, other setting methods can also be used. For example, Figure 6 As shown in FIG. 8, in some embodiments, the inner liner 212 is also provided with a second interval part 2122. In the width direction X1, the second cavity and the third cavity are arranged at intervals by the second interval part 2122; and the fourth cavity and the first cavity are arranged at intervals by the second interval part 2122. In other embodiments, the second interval part 2122 can be formed only between the second cavity and the third cavity, or the second interval part 2122 can be formed only between the fourth cavity and the first cavity, which can be determined according to the use needs.

[0120] It should be noted that, Figure 6 The dashed lines L1 and L2 in FIG. 7 are the boundary lines between the first interval part 2121 and the second interval part 2122.

[0121] In the embodiment, the second interval part 2122 can also be part of the inner liner 212, which is protrudingly arranged compared with the bottom surface of the first accommodating cavity and the bottom surface of the second accommodating cavity. The shape, size and arrangement position of the second interval part 2122 can be determined according to the use needs. For example, Figure 6 As shown in FIG. 8, the second interval part 2122 can be arranged to be longer to completely separate the second cavity and the third cavity; or the second interval part 2122 can be arranged to be shorter to separate only a part of the second cavity and the third cavity. When the second interval part 2122 is arranged to be shorter, the second interval part 2122 can be arranged at the end (one end or both ends) of the interval region between the second cavity and the third cavity; or the second interval part 2122 can be arranged at the center of the above interval region to separate the middle part of the second cavity and the third cavity.

[0122] In this way, after the two earphones 10 are placed into the earphone box 20, the connecting arm 12 of at least one earphone 10 is spaced apart from the first earphone body 11 of the other earphone 10, which facilitates the user to hold the connecting arm 12, and thus facilitates the user to take out the earphone 10 from the earphone box 20, and also facilitates the user to place the earphone 10 into the earphone box 20. In addition, the second spacing portion 2122 can also play a certain limiting role on the first earphone body 11 of the earphone 10, so as to limit the first earphone body 11 of the earphone 10 in the second cavity or the fourth cavity, and also play a certain supporting role, so as to reduce the risk of the earphone 10 from being tilted after being placed into the earphone box 20, and make the earphone 10 be able to be fixed at the corresponding position, which is helpful for the stable placement of the earphone 10.

[0123] As shown in Figure 6 In some embodiments, the first spacing portion 2121 and the second spacing portion 2122 are both arranged in the inner liner 212. The at least one second spacing portion 2122 is connected with the at least one first spacing portion 2121. The connected first spacing portion 2121 and second spacing portion 2122 form a combined spacing portion 2125. At least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart by the combined spacing portion 2125.

[0124] The present embodiment includes various implementation manners. For the convenience of understanding, the following examples are given:

[0125] Firstly, a plurality of first spacing portions 2121 and a plurality of second spacing portions 2122 are arranged, the adjacent two first spacing portions 2121 are spaced apart, any second spacing portion 2122 is connected with the bottom and the side wall of the main body portion 2124 of the inner liner 212, and the adjacent first spacing portion 2121 and second spacing portion 2122 are connected to form a combined spacing portion 2125. At least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart by the plurality of combined spacing portions 2125.

[0126] Secondly, a plurality of first spacing portions 2121 and a plurality of second spacing portions 2122 are arranged, the adjacent two first spacing portions 2121 are spaced apart, any second spacing portion 2122 is spaced apart from the side wall of the main body portion 2124 of the inner liner 212, and the adjacent first spacing portion 2121 and second spacing portion 2122 are connected to form a combined spacing portion 2125. At least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart by the plurality of combined spacing portions 2125.

[0127] Thirdly, as shown in Figure 6As shown, the first spacing part 2121 is provided with one, and the second spacing part 2122 is provided with two, and the two second spacing parts 2122 and the first spacing part 2121 are connected to form a combined spacing part 2125; both ends of the combined spacing part 2125 are connected with the side wall of the main body part 2124 of the inner liner 212; and the whole of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart by the combined spacing part 2125.

[0128] In addition, the first spacing part 2121 and the second spacing part 2122 can also be connected in other ways, which can be determined according to the needs of use.

[0129] Regardless of which way is adopted, by adopting the scheme provided in this embodiment, in the first aspect, after the two earphones 10 are placed into the earphone box 20, the connecting arm 12 of any one earphone 10 is spaced apart from the first earphone body 11 of the other earphone 10, which facilitates the user to hold the connecting arm 12, thereby facilitating the user to take out the earphone 10 from the earphone box 20, and also facilitating the user to put the earphone 10 into the earphone box 20; in the second aspect, at least part of the first accommodating cavity 213a and the second accommodating cavity 213b are spaced apart, and after the two earphones 10 are placed into the earphone box 20, the risk of mutual interference is relatively small; in the third aspect, the combined spacing part 2125 can play a certain limiting and supporting role on the earphone 10, which reduces the risk of the earphone 10 from falling and moving after being placed into the earphone box 20, and can make the earphone 10 be fixed at the corresponding position, which is helpful for the stable placement of the earphone 10.

[0130] As shown in the above embodiment, Figure 5 In order to facilitate the taking and placing of the earphone 10, in some embodiments, the first accommodating cavity 213a has a lowest point in the height direction. At least part of the side of the combined spacing part 2125 away from the lowest point in the height direction is a curved surface recessed toward the side where the lowest point is located.

[0131] The inner wall of the first accommodating cavity 213a can be formed by one curved surface or a plurality of curved surfaces spliced together. The lowest point of the first accommodating cavity 213a in the height direction is the point with the largest depth in the height direction among the points in the inner wall of the first accommodating cavity 213a.

[0132] In this way, after the earphone 10 is placed into the first accommodating cavity 213a or the second accommodating cavity 213b, the connecting arm 12 will not interfere with the first accommodating cavity 213a or the second accommodating cavity 213b, and more parts of the connecting arm 12 can protrude out of the combined spacing part 2125, which facilitates the user to hold, thereby facilitating the taking and placing operation of the earphone 10.

[0133] Figure 8 In order to facilitate the taking and placing of the earphone 10, Figure 6A cross-sectional view of the middle B-B line; Figure 9 For Figure 8 A partial enlarged view of the middle A.

[0134] As Figure 8 And Figure 9 As shown in some embodiments, the first housing 211 and the inner liner 212 form a mounting space 214 therebetween. The inner liner 212 is provided with a plurality of through structures 2123. The first accommodating cavity 213a is in communication with the mounting space 214 through at least one through structure 2123, and the second accommodating cavity 213b is in communication with the mounting space 214 through at least one through structure 2123. The first part 21 further comprises a spring 215d. The spring 215d is arranged in correspondence with the through structure 2123. A part of the spring 215d is arranged in the mounting space 214, and the other part is inserted into the first accommodating cavity 213a or the second accommodating cavity 213b through the through structure 2123.

[0135] The spring 215d is a charging terminal for contacting the charging contact on the earphone 10, and is part of the charging module 215 in the first part 21. The charging module 215 further comprises a battery and a circuit board, etc. in addition to the spring 215d. The battery and the spring 215d are both connected with the circuit board. The spring 215d is provided in two groups. Each group is generally provided with two springs 215d. That is, the first accommodating cavity 213a corresponds to two springs 215d, and the second accommodating cavity 213b corresponds to two springs 215d. In the same accommodating cavity, one spring 215d is used for contacting the positive charging contact of the earphone, and the other spring 215d is used for contacting the negative charging contact of the earphone.

[0136] The spring 215d is arranged in correspondence with the through structure 2123. The spring 215d can be arranged in one-to-one correspondence with the through structure 2123, or a plurality of springs 215d can be arranged in the same through structure 2123. It can be understood that when a plurality of springs 215d are arranged in the same through structure 2123, a large spacing distance is required between the plurality of springs 215d, or an insulating structure is arranged between the plurality of springs 215d, so that short circuit does not occur between the plurality of springs 215d.

[0137] The spring 215d has the characteristics of simple structure, strong anti-oxidation ability and high stability compared with the charging needle.

[0138] Compared with the charging terminal adopting a charging pin, the charging terminal adopts the spring sheet 215d. In the first aspect, when the earphone 10 is placed into the earphone box 20 after being moved or used daily and getting sweat, the salt in the sweat is not easy to corrode the charging terminal, and the contact surface of the spring sheet 215d is flat, so that the sweat stain can be easily cleaned (cotton swab wiping is enough). In the second aspect, the spring sheet 215d contacts the charging contact of the earphone 10 by plane pressure, so that even if the surface of the charging contact of the earphone 10 has a slight sweat or water film, the spring sheet 215d can still keep conduction with the charging contact (current passes through the liquid film to form a path), and the spring sheet 215d can tolerate a high degree of placement angle of the earphone 10, and slight deviation can also charge. In the third aspect, the spring sheet 215d has high yield rate in mass production, and is convenient to repair and replace.

[0139] As shown in Figure 9 The spring sheet 215d includes a first sheet body 215d3 and a second sheet body 215d4 arranged at an included angle. The first sheet body 215d3 is arranged in the mounting space 214, and at least part of the first sheet body 215d3 is arranged along the height direction Z. The second sheet body 215d4 is arranged at an included angle with the first sheet body 215d3, and at least part of the second sheet body 215d4 is located in the first accommodating cavity 213a or the second accommodating cavity 213b. The distance between at least part of the second sheet body 215d4 and the first sheet body 215d3 decreases along the third direction. The third direction is the direction from the opening of the first accommodating cavity 213a to the bottom surface.

[0140] As shown in the view angle Figure 9 The top of the first sheet body 215d3 and the second sheet body 215d4 is connected, and the bottom of the second sheet body 215d4 is arranged at an interval from the first sheet body 215d3.

[0141] During the process of placing the earphone 10 into the earphone box 20, the earphone 10 is placed into the accommodating cavity from top to bottom. During this process, since the interval between the second sheet body 215d4 and the first sheet body 215d3 generally presents a gradually increasing trend from top to bottom, the protruding height of the second sheet body 215d4 in the accommodating cavity gradually increases, and the pressure of the earphone 10 on the second sheet body 215d4 gradually increases, so that the earphone 10 is finally pressed tightly with the spring sheet 215d after falling onto the bottom surface of the accommodating cavity, and the earphone 10 can keep the state of being pressed tightly with the spring sheet 215d under the action of gravity. This helps the charging contact on the earphone 10 to stably contact the spring sheet 215d, so that the earphone 10 can be stably charged.

[0142] As shown in Figure 9As shown, in order to enable the elastic sheet 215d to stably contact the charging contact of the earphone after the earphone 10 is placed, in some embodiments, the inner liner 212 has a first face 212a and a second face 212b arranged opposite to each other. The first face 212a encloses a first accommodating cavity 213a. The second face 212b is provided with a limiting structure 2126. The first face 212a is the front face of the inner liner 212, and the second face 212b is the back face of the inner liner 212. The limiting structure 2126 and the second face 212b form a mounting channel 2127. The mounting channel 2127 is in communication with the through structure 2123 and the mounting space 214. At least part of the elastic sheet 215d is arranged in the mounting channel 2127 and abuts against the limiting structure 2126.

[0143] The limiting structure 2126 can be a plate body, or a U-shaped structure, a C-shaped structure, or other shapes, which can be determined according to the use requirements. The limiting structure 2126 can be integrally formed with the inner liner 212, or can be separately connected (such as inserted, clamped, etc.) with the inner liner 212.

[0144] The limiting structure 2126 can be a plate body, or a U-shaped structure, a C-shaped structure, or other shapes, which can be determined according to the use requirements. The limiting structure 2126 can be integrally formed with the inner liner 212, or can be separately connected (such as inserted, clamped, etc.) with the inner liner 212.

[0145] On the basis of the above embodiments, in order to further limit the relative position of the elastic sheet 215d and the mounting channel 2127, in some embodiments, the limiting structure 2126 has a stop face 21261. The elastic sheet 215d has a limiting portion 215d2. The limiting portion 215d2 can contact the stop face 21261 to limit the length of the elastic sheet 215d inserted into the mounting channel 2127.

[0146] Specifically, the stop face 21261 is a face on the limiting structure 2126, which is located at the entrance of the mounting channel 2127.

[0147] The elastic sheet 215d includes a connecting portion 215d1 and a limiting portion 215d2 connected to each other. The connecting portion 215d1 includes the first sheet body 215d3 and the second sheet body 215d4. The connecting portion 215d1 is connected to the main plate. The limiting portion 215d2 is protruded from the side wall of the connecting portion 215d1 and at least partially protrudes into the mounting channel 2127. The part of the limiting portion 215d2 protruding into the mounting channel 2127 is used to contact the stop face 21261.

[0148] The spring piece 215d may include only the connecting portion 215d1 and the limiting portion 215d2 according to usage requirements, or may include other parts in addition to the connecting portion 215d1 and the limiting portion 215d2, such as a flexible part connecting the limiting portion 215d2 and the main board 217, etc., which can be determined according to usage requirements.

[0149] Through the cooperation between the stop surface 21261 and the limiting portion 215d2 in the spring clip 215d, the length of the portion of the spring clip 215d inserted into the installation channel 2127 can be limited, so that the relative positions of the spring clip 215d and the installation channel 2127 and the first accommodating cavity 213a or the second accommodating cavity 213b in different products are the same, so that the earphone box 20 has high stability during mass production. After the earphone 10 is placed in the earphone box 20, the charging contacts on the earphone 10 can correspond to the position of the protrusion on the spring clip 215d, and are in stable contact with the spring clip 215d.

[0150] like Figure 6 As shown, in some embodiments, the side wall of the first accommodating cavity 213a includes a first curved surface. The first curved surface has multiple first corner areas. At least some of the first corner areas are arranged away from the second accommodating cavity 213b. The through structure is arranged in at least one corner area away from the second accommodating cavity 213b. The side wall of the second accommodating cavity 213b includes a second curved surface, the second curved surface has multiple second corner areas, at least some of the second corner areas are arranged away from the first accommodating cavity 213a, and the through structure is arranged in at least one second corner area away from the first accommodating cavity 213a. In other embodiments, the through structure in the first accommodating cavity 213a may adopt the above-mentioned setting method, or the through structure in the second accommodating cavity 213b may adopt the above-mentioned setting method, which can be determined according to the specific needs of use.

[0151] Generally, the inner walls of the first accommodating cavity 213a and the second accommodating cavity 213b each include a bottom surface and a side wall surrounding the bottom surface. The side wall includes a curved surface with multiple corner areas. The side wall can be composed of only a curved surface, or it can also have a flat surface in addition to the curved surface, which can be determined according to the specific needs of use. The curved surface has at least two or more corner areas. And the radius of the curved surface corresponding to the corner area is smaller than the radius of the curved surface corresponding to other areas. In this way, the distance between the curved surface in the corner area and the inner wall or outer wall of the first shell 211 is larger. The through structure is provided in at least one corner area away from the other accommodating cavity, which can make the thickness of the first shell 211 less likely to be thickened due to the provision of the spring 215d, which helps to reduce the volume of the earphone box 20. The through structure and the spring are provided in the corner area away from the other accommodating cavity, which can make the appearance of the first part 21 beautiful to a certain extent.

[0152] like Figure 6As shown, in some embodiments, at least part of the inner wall of the first accommodating cavity 213a is symmetrical relative to a first symmetry plane, at least part of the inner wall of the second accommodating cavity 213b is symmetrical relative to a second symmetry plane, and the first symmetry plane and the second symmetry plane are parallel to each other.

[0153] The inner wall of the first accommodating cavity 213a and the inner wall of the second accommodating cavity 213b can each be formed by one or more planes and / or curved surfaces. At least one plane and / or curved surface is arranged symmetrically and has a symmetry plane. Among the above symmetry planes, the symmetry plane extending in the first direction is the first symmetry plane or the second symmetry plane. As shown in the drawings, Figure 6 As shown, the first symmetry plane corresponding to the inner wall of the first accommodating cavity is a plane defined by the first connecting line L3 in the drawing and the third direction, and the second symmetry plane corresponding to the inner wall of the second accommodating cavity is a plane defined by the second connecting line L4 in the drawing and the third direction.

[0154] At least part of the inner wall of the first accommodating cavity 213a is symmetrical relative to a predetermined symmetry plane. The predetermined symmetry plane can be a symmetry plane relative to which the bottom surface of the first accommodating cavity 213a is symmetrical, or a symmetry plane relative to which the entire inner wall of the first accommodating cavity 213a is symmetrical, or a symmetry plane relative to which the side wall of the first accommodating cavity 213a is symmetrical, or other arrangements, which can be determined according to design requirements.

[0155] By using the scheme provided in this embodiment, at least part of the inner wall of the first accommodating cavity 213a is a symmetrical structure, and the symmetry planes (the first symmetry plane and the second symmetry plane) corresponding to the first accommodating cavity 213a and the second accommodating cavity 213b are parallel to each other, which not only facilitates the design of the first accommodating cavity 213a and the second accommodating cavity 213b, but also makes the structure of the first accommodating cavity 213a and the second accommodating cavity 213b compact, the spacing space between the two is small, the occupied space is small, and the miniaturization design of the earphone box 20 is facilitated.

[0156] In some embodiments, the first accommodating cavity 213a corresponds to two through structures. In the first accommodating cavity 213a, the two through structures are arranged on the two sides of the first symmetry plane, and the elastic sheet 215d is arranged one-to-one corresponding to the through structure. In other embodiments, the second accommodating cavity corresponds to two through structures; in the second accommodating cavity, the two through structures are arranged on the two sides of the second symmetry plane, and the elastic sheet is arranged one-to-one corresponding to the through structure. In other embodiments, the first accommodating cavity corresponds to two through structures; in the first accommodating cavity, the two through structures are arranged on the two sides of the first symmetry plane, and the elastic sheet is arranged one-to-one corresponding to the through structure; and the second accommodating cavity corresponds to two through structures; in the second accommodating cavity, the two through structures are arranged on the two sides of the second symmetry plane, and the elastic sheet is arranged one-to-one corresponding to the through structure.

[0157] Compared with setting two through structures adjacent to each other in the same accommodating cavity, the distance between the two through structures can be larger, thereby making the distance between the two spring pieces 215d in the same accommodating cavity larger, which can reduce the risk of short circuit between the two spring pieces 215d and the two charging contacts of the earphone 10 to a certain extent.

[0158] In the above embodiments, the earphone 10 can be limited by the side wall of the first accommodating cavity 213a and the spacers, so that the earphone 10 can be stably contacted with the spring piece 215d after being placed in the first accommodating cavity 213a. In order to further limit the relative position of the earphone 10 and the spring piece 215d, as shown in FIG. Figure 3 As shown, in some embodiments, the first part 21 also includes a magnet module 219 provided in the installation space 214. The magnet module 219 is provided between the two through structures 2123. In this way, after the earphone 10 is placed in the first accommodating cavity 213a, the magnet module 219 can limit the relative position of the earphone 10 and the lining 212 through magnetic adsorption, so as to reduce the risk of the earphone 10 moving under the action of external force after being placed in the first accommodating cavity 213a, so that the charging contacts on the earphone 10 can always be in stable contact with the elastic sheet 215d. And the setting of the magnet module 219 does not occupy the installation space of the elastic sheet 215d. The above-mentioned magnet module 219 corresponds one-to-one to the first accommodating cavity 213a. The same magnet module 219 can include one or more magnetic parts, such as one or more permanent magnets, one or more electromagnets, etc., which can be determined according to the specific needs of use.

[0159] In order to fix the position of the magnet module 219, an installation groove for limiting the installation position of the magnet module can be provided on the second surface 212b of the lining 212, so that the installation positions of the magnet modules 219 of different products are the same and the positioning effect of the earphone 10 is the same.

[0160] Figure 10 The earphone box provided in one embodiment of the present application is Figure 1 Schematic diagram of the cross-sectional structure of the CC line. Figure 11 for Figure 10 Schematic diagram of the local enlarged structure at point B in the middle.

[0161] like Figure 10 and Figure 11As shown, in some embodiments, the earphone box 20 further comprises a second part 22. The second part 22 is provided with a third accommodating cavity 221. The second part 22 is movable relative to the first part 21 between a first position and a second position. In the first position, the second part 22 is buckled with the first part 21, and the third accommodating cavity 221 is in communication with the first accommodating cavity 213a and the second accommodating cavity 213b respectively. In the second position, the second part 22 exposes the first accommodating cavity and the second accommodating cavity. The inner wall of the third accommodating cavity 221 is provided with a positioning structure 222. The positioning structure 222 is used to define the position of the earphone.

[0162] As described above, the second part 22 can be detachably connected with the first part 21, or rotatably connected with the first part 21, or connected with the first part 21 in other ways, which can be determined according to the needs of use.

[0163] The second part 22 can protect the earphone to some extent and reduce the risk of damage to the earphone after being placed in the earphone box 20. The positioning structure 222 in the embodiment can define the position of the earphone in the earphone box alone or in cooperation with other components. For example, the positioning structure 222 can be an elastic structure, a clamping structure, a plug-in structure, etc. The relative position of the second earphone body and the earphone box can be defined by abutting, frictional contact, plug-in, etc. with the second earphone body 13, so as to reduce the risk of shaking of the earphone in the earphone box 20 after being placed in the earphone box 20.

[0164] As shown in Figure 10 and Figure 11 As shown, in some embodiments, the positioning structure 222 comprises an elastic member 2221. The elastic member 2221 covers at least part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221; or covers at least part of the projection area of the second accommodating cavity 213b in the third accommodating cavity; or covers at least part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221 and covers at least part of the projection area of the second accommodating cavity 213b in the third accommodating cavity.

[0165] The elastic member 2221 refers to a member with a certain elasticity, which can be made of materials with elasticity such as silica gel and rubber. The positioning structure 222 comprises the elastic member 2221, which can reduce the risk of hard collision between the positioning structure 222 and the second earphone body 13, thereby reducing the risk of damage to the second earphone body 13.

[0166] Figure 12 The bottom structure schematic view of the assembly structure of the first part and the pivot structure in the earphone box of another embodiment of the present application is provided.

[0167] The above scheme includes various cases. For ease of understanding, the case that the elastic member 2221 covers at least part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221 is taken as an example for description.

[0168] The elastic member 2221 covers at least part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221, which includes various cases. For ease of understanding, the cases are taken as examples for description. In a first case, as shown in Figure 10 and Figure 11 , the elastic member 2221 covers the entire part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221, and in addition, the elastic member 2221 can also cover other areas of the third accommodating cavity 221; in a second case, as shown in Figure 12 , the elastic member 2221 only covers part of the projection area of the first accommodating cavity 213a in the third accommodating cavity 221. In other embodiments, the elastic member 2221 can also adopt other settings, as long as the elastic member 2221 can contact the second earphone body 13 to exert a pressure on the second earphone body 13 towards the first earphone body 11 when the first part 21 and the second part 22 are buckled.

[0169] In this way, at least part of the elastic member 2221 can contact the second earphone body 13 to exert a pressure on the second earphone body 13 towards the first earphone body 11 when the first part 21 and the second part 22 are buckled, which can be understood with reference to Figure 2 , so that the elastic member 2221 and the inner liner 212 can cooperate with each other to realize clamping of the earphone 10, thereby reducing the risk of shaking of the earphone 10 in the earphone box 20.

[0170] As shown in Figure 10 and Figure 11 , in some embodiments, the second part 22 includes a rigid member 22a. The third accommodating cavity 221 is arranged on the rigid member 22a, that is, the third accommodating cavity 221 is arranged on the rigid member 22a.

The second plug-in part is plug-in matched with the first plug-in part 2222. The elastic member 2221 is plug-in matched with the rigid member 22a through the second plug-in part and the first plug-in part 2222.

[0175] The first plug-in part 2222 can be integrally formed with the elastic member 2221, or can be separately connected with the elastic member 2221, which can be determined according to the use requirement.

[0176] The first plug-in part 2222 and the second plug-in part are two components plug-in matched, for example, the first plug-in part 2222 is a protruding structure, and the second plug-in structure can be a recessed structure, for example, the first plug-in part 2222 is a recessed structure, and the second plug-in part can be a protruding structure. Specifically, when the first plug-in part 2222 is plug-in matched with the second plug-in part, the two can be interference fit, or can be gap fit, or can be friction contact, which can be determined according to the use requirement.

[0177] The second plug-in part and the first plug-in part 2222 are provided, realizing the detachable connection of the rigid member 22a and the elastic member 2221, so that the elastic member 2221 is not easy to separate from the rigid member 22a, and the replacement and maintenance of the elastic member 2221 are facilitated.

[0178] In some embodiments, the elastic member 2221 is a silica gel member.

[0179] The elastic member 2221 adopts a silica gel member, which can make the elastic member 2221 have good waterproof and sweatproof properties, stable performance, and can reduce the risk of elastic failure of the elastic member 2221 in extreme weather (such as winter outdoor or summer high temperature in the car).
