Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to a housing assembly and an electronic device. Background Technology

[0002] Tablets, mobile phones, and other electronic devices are typically equipped with microphones (MICs) to pick up ambient sound, enabling functions such as recording, making calls, and video recording. Since the microphone is located inside the device, a pickup channel needs to be designed to connect it to the external sound source. However, current pickup channel designs occupy a significant amount of space in the device, hindering the creation of thinner and lighter designs. Summary of the Invention

[0003] Some embodiments of this application provide a housing assembly and an electronic device. The following describes this application from multiple aspects, and the embodiments and beneficial effects of the following aspects can be referred to each other.

[0004] In a first aspect, embodiments of this application provide a housing assembly. The housing assembly includes a main body and a cover plate. The main body includes a first support portion and a second support portion connected together. The first support portion supports functional components of an electronic device in which the housing assembly is located, and the second support portion supports the display screen of the electronic device. The first and second support portions together form a first groove, wherein at least a portion of the first support portion constitutes the bottom wall and a portion of the side wall of the first groove, and at least a portion of the second support portion constitutes another portion of the side wall of the first groove. The opening of the first groove faces the thickness direction of the housing assembly. The cover plate covers the opening of the first groove and, together with the first groove, forms a first channel segment.

[0005] The aforementioned housing assembly utilizes a middle frame and a cover plate to jointly form the first channel segment. The cover plate's thickness design does not need to consider the manufacturability of the channel segment. Therefore, the cover plate's thickness can be set as small as possible, thereby effectively reducing the wall thickness of the first channel segment and consequently reducing the overall stacking thickness.

[0006] In some implementations, the first channel segment may be at least a portion of the microphone assembly's pickup channel segment, used to implement the microphone assembly's pickup function.

[0007] In some implementations, the functional component of the electronic device in which the housing assembly is located can be a microphone assembly.

[0008] In some embodiments, the main body includes a first support portion and a second support portion connected together. The first support portion supports a microphone assembly of an electronic device housing the casing assembly, and the second support portion supports a display screen of the electronic device housing the casing assembly. The first and second support portions together form a first groove. At least a portion of the first support portion constitutes the bottom wall and a portion of the side wall of the first groove, and at least a portion of the second support portion constitutes another portion of the side wall of the first groove.

[0009] In some embodiments, the cover plate includes a first edge portion and a second edge portion, and at least a portion of the cover plate forms a first channel wall of a first channel segment, the first edge portion and the second edge portion surrounding the first channel wall, the first edge portion covering a first support portion, and the second edge portion covering a second support portion.

[0010] In some embodiments, a second groove is provided on the second support portion, the opening of the second groove faces the second edge portion, the second edge portion covers the inner surface of the groove wall of the second groove, and the outer surface of the groove wall of the second groove is used to support the display screen of the electronic device in which the housing assembly is located.

[0011] According to the embodiments of this application, the groove wall of the second groove can provide certain support for the second edge portion of the cover plate, thereby further improving the stability of the cover plate installation. Simultaneously, the groove wall of the second groove can also provide certain support for the display screen, preventing the display screen from denting inward at the second groove when subjected to external force.

[0012] In some embodiments, a second channel segment is provided on the second support portion, the second channel segment penetrating another part of the sidewall of the first groove to connect the first channel segment with the outside of the housing assembly.

[0013] In some implementations, the second channel segment may be at least a portion of the microphone assembly's pickup channel segment, used to implement the microphone assembly's pickup function.

[0014] In some embodiments, the inlet of the second channel segment is connected to the outer surface of the second support, and the inlet of the second channel segment overlaps with the center of the outer surface of the second support along the thickness direction of the housing assembly.

[0015] According to an embodiment of this application, the entrance of the second channel segment is located on the outer surface of the housing assembly. The entrance of the second channel segment overlaps with the center of the outer surface of the second support portion along the thickness direction of the housing assembly, ensuring that the position of the entrance of the second channel segment is not excessively high or low. When observing the outer surface of the housing assembly, the entrance of the second channel segment is visually positioned in a more symmetrical manner, thereby effectively enhancing the overall refinement and aesthetics of the housing assembly.

[0016] In some embodiments, along the thickness direction of the housing assembly, the inlet of the second channel segment is further away from the bottom wall of the first groove than the outlet of the second channel segment. This avoids interference between the second channel segment and the second edge portion of the cover plate without increasing the thickness space occupied by the first channel segment.

[0017] In some embodiments, along the extension direction of the cover plate, the first end of the second edge portion is further away from the first channel wall than the second end of the second edge portion, and along the thickness direction of the housing assembly, the first end of the second edge portion is further away from the bottom wall of the first groove than the second end of the second edge portion. In this way, interference between the second edge portion of the cover plate and the second channel segment can be avoided without increasing the thickness space occupied by the first channel segment.

[0018] In some embodiments, the cover plate includes a first plate and a second plate, the second plate being inclined relative to the first plate toward the bottom wall away from the first groove, and the second plate overlapping the second support portion.

[0019] According to an embodiment of this application, the second plate can overlap the second support portion via its second edge portion. Since the second plate is inclined relative to the first plate towards the bottom wall away from the first groove, interference between the second edge portion and the second channel segment can be effectively avoided. Furthermore, the space of the first channel segment can be increased without increasing the thickness.

[0020] In some embodiments, the direction from the first end of the second edge portion to the second end of the second edge portion is parallel to the extension direction of the second channel segment. The second channel segment is formed on the main body, and the second edge portion overlaps the main body. Therefore, this arrangement of the second edge portion and the second channel segment can help reduce stress concentration in the main body and improve the overall assembly stability of the housing assembly.

[0021] In some embodiments, the wall thickness of the first channel can be 0.2 mm to 0.3 mm, for example, 0.2 mm, 0.21 mm, 0.22 mm, 0.23 mm, etc. This can effectively reduce the thickness space required to form the first channel segment.

[0022] In some embodiments, a through hole is provided on the wall of the first channel, and the through hole communicates with the first channel segment. This allows the first channel segment to communicate with other devices (such as a microphone assembly).

[0023] In some implementations, the cover plate is made of steel sheet, copper sheet, aluminum sheet, plastic sheet, or Mylar sheet.

[0024] In some implementations, the main body is made of metal or plastic.

[0025] In some embodiments, a first sealing assembly is provided at the connection between the cover plate and the body, and the orthographic projection area of ​​the first sealing assembly on the first plane is located outside the orthographic projection area of ​​the first channel wall on the first plane, wherein the first plane is the plane containing the length and width directions of the housing assembly.

[0026] According to the embodiments of this application, the first sealing assembly can improve the sealing performance between the middle frame and the cover plate. Furthermore, since the orthographic projection area of ​​the first sealing assembly on the first plane is located outside the orthographic projection area of ​​the first channel wall on the first plane, the first sealing assembly can prevent it from obstructing the first channel wall.

[0027] In some embodiments, the first sealing component includes foam, which is bonded to the cover plate and the main body via adhesive. The foam allows for a flexible fit between the middle frame and the cover plate, fully filling the installation gap between them, thereby achieving a sealing effect and improving sealing reliability. The foam can also be bonded to the middle frame and the cover plate via adhesive, thus achieving a fixed connection between the cover plate and the middle frame.

[0028] Secondly, embodiments of this application provide an electronic device. The electronic device includes a microphone assembly and a housing assembly provided in any embodiment of the first aspect of this application. The microphone assembly is disposed on the surface of a cover plate facing away from the first channel segment, and a through hole is formed in the cover plate, the through hole connecting the first channel segment and the microphone assembly.

[0029] It should be understood that the beneficial effects of the second aspect mentioned above can be referred to the description of the first aspect mentioned above, and will not be repeated here.

[0030] In some embodiments, the main body includes a first support and a second support connected together, the first support supporting the microphone assembly and the second support supporting the screen of the electronic device.

[0031] In some implementations, the main body is the mid-frame of the electronic device.

[0032] In some embodiments, a second sealing assembly is provided at the connection between the microphone assembly and the cover plate. The second sealing assembly includes a dustproof mesh and foam. The area of ​​the foam projected onto the first plane is located outside the area of ​​the through-hole projected onto the first plane, which is the plane containing the length and width directions of the housing assembly.

[0033] According to the embodiments of this application, the second sealing component can improve the sealing performance between the cover plate and the microphone assembly. The foam allows for a flexible fit between the cover plate and the microphone assembly, fully filling the installation gap between them, thereby achieving a sealing effect and improving sealing reliability. The dustproof mesh has a fine mesh structure, effectively preventing dust, fine particles, and other debris from entering the microphone assembly, thus avoiding blockage or damage and extending the lifespan of the microphone assembly. Furthermore, the projection area of ​​the foam onto the first plane can be located outside the projection area of ​​the through-hole on the first plane, thus preventing the foam from obstructing the through-hole.

[0034] In some implementations, the electronic device includes a bracket that presses the microphone assembly and cover plate onto the body.

[0035] According to the embodiments of this application, the bracket can provide a certain compressive force to the cover plate and the microphone assembly. Therefore, the main body, cover plate, and microphone assembly can fit tightly together, and the sealing components between any two adjacent components are under compression. This allows the sealing components to more fully fill the installation gaps between the main body and cover plate, and between the cover plate and the microphone assembly, thereby achieving a reliable seal.

[0058] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0059] This application provides a housing assembly that can be applied to an electronic device. Specifically, the electronic device includes, but is not limited to, any one of the following: tablets, mobile phones, laptops, cameras, ultra-mobile personal computers (UMPCs), handheld computers, touch-screen TVs, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices, virtual reality devices, smart vehicles, smart robots, industrial equipment, and other electronic devices with microphones. This application does not limit the scope of the application to these devices. For ease of description, a tablet is used as an example below.

[0060] Figure 1 An exemplary structural diagram of a plate 1 according to an embodiment of this application is shown. In the figures herein, the X direction is the length direction of the plate 1, the Y direction is the width direction of the plate 1, and the Z direction is the thickness direction of the plate 1. The X, Y, and Z directions are perpendicular to each other. (Reference) Figure 1 The dimensions of the flat plate 1 in both the length and width directions are larger than the dimensions of the flat plate device 1 in the thickness direction. In other words, the flat plate 1 has the smallest dimension in the thickness direction.

[0061] It is understood that the perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of mutual perpendicularity in this application. Similarly, the parallelism in this application is not absolute parallelism. Approximate parallelism due to processing and assembly errors (e.g., an angle of 0.1° between two structural features) is also within the scope of mutual parallelism in this application. The definitions of mutual parallelism and mutual perpendicularity will not be repeated below.

[0062] Additionally, it should be noted that the directional terms such as "upper," "lower," "left," "right," "front," "back," "top," and "bottom" used in this document are exemplary orientations of the plate 1, and do not indicate or imply that the components referred to must have a specific orientation. These orientations may vary depending on actual use and should not be construed as limitations on this application.

[0063] refer to Figure 1The tablet 1 includes a housing assembly 01, a display screen 02, a microphone assembly 03, and a motherboard 04. The housing assembly 01 may include a mid-frame 10 and a rear shell 11. In some embodiments, the mid-frame 10 and the rear shell 11 may be a single-piece structure; for example, the mid-frame 10 and the rear shell 11 may be made of plastic and formed as a single piece through injection molding. In other embodiments, the mid-frame 10 and the rear shell 11 may be formed separately and then assembled together to form a single-piece structure. Along the Z-direction, the rear shell 11 and the display screen 02 are respectively mounted on opposite sides of the mid-frame 10, thereby jointly forming a receiving cavity 05.

[0064] Microphone assembly 03 and motherboard 04 are respectively disposed within receiving cavity 05. In some embodiments, microphone assembly 03 may include circuit board assembly 031 and microphone unit 032. Circuit board assembly 031 may include a printed circuit board and a flexible circuit board. Microphone unit 032 is disposed on the printed circuit board of circuit board assembly 031 and electrically connected to motherboard 04 via the flexible circuit board of circuit board assembly 031. Sound emitted from an external sound source can be transmitted to microphone assembly 03 inside tablet 1. Microphone assembly 03 then converts the sound signal into an electrical signal, which is then processed (e.g., amplified, filtered, etc.) by circuit board assembly 031 and transmitted to motherboard 04. The processor on motherboard 04 can further process, analyze, or store the audio signal from the microphone.

[0065] In order for the microphone assembly 03 inside the tablet 1 to pick up sound emitted from external sound sources, a sound pickup channel is usually formed on the housing assembly 10 of the tablet 1. The sound pickup channel is used to connect the microphone assembly 03 and the outside of the tablet 1.

[0066] Understandable. Figure 1 In the example shown, the microphone assembly 03 is positioned near the left side of the tablet 1, and correspondingly, the sound pickup channel communicates with the outside of the tablet 1 via the left side of the tablet 1. However, this application is not limited to this. In other embodiments, the microphone assembly 03 can be positioned in other locations, such as near the bottom edge of the tablet 1, and correspondingly, the sound pickup channel communicates with the outside of the tablet 1 via the bottom edge of the tablet 1. Furthermore, this application does not impose a specific limitation on the number of microphone assemblies 03; the number of microphone assemblies 03 can be one or more, and correspondingly, the same number of sound pickup channels are formed on the housing assembly 10 of the tablet 1. For example, in some embodiments, the tablet 1 can be equipped with two microphone assemblies 03, which, in addition to collecting audio signals, can also achieve noise reduction. In other embodiments, the tablet 1 can be equipped with three, four, or more microphones 03, which can achieve audio signal collection, noise reduction, sound source identification, and directional recording, etc.

[0067] The following section uses a microphone assembly 03 located near the left side of the tablet 1 as an example to introduce several pickup channels corresponding to the microphone assembly 03, as well as exemplary structures of housing assemblies used to form the pickup channels.

[0068] Figure 2A This diagram illustrates a housing assembly structure in which a pickup channel 100a is formed in a flat panel 1, as shown in some technical solutions. For ease of observation, Figure 2A The path of pickup channel 100a is shown in the dashed line. (Reference) Figure 2A In some technical solutions, the pickup channel 100a is located on the middle frame 10a.

[0069] Specifically, the middle frame 10a includes a first support portion 101a and a second support portion 102a connected to each other. The first support portion 101a supports the microphone assembly 03. A first channel segment 110a is formed on the first support portion 101a. The first channel segment 110a communicates with the microphone assembly 03. The second support portion 102a supports the display screen 02. A second channel segment 120a is formed on the second support portion 102a. The second channel segment 120a connects the first channel segment 110a and the outside of the tablet 1. The first channel segment 110a and the second channel segment 120a constitute a sound pickup channel 100a.

[0070] It is understandable that the smaller the wall thickness of the first channel segment 110a, for example, the smaller the wall thickness D1a, the smaller the stacking thickness D2a between it and the microphone component 03, which is beneficial to the thin and light design of the tablet 1.

[0071] However, the first channel segment 110a is formed (e.g., by drilling) on ​​the first support portion 101a of the mid-frame 10a. If the wall thickness of the first channel segment 110a, for example, the wall thickness D1a, is small, the first support portion 101a is prone to cracking or collapsing during the processing of the first channel segment 110a, thus making it impossible to form the first channel segment 110a. Therefore, to ensure the machinability of the first channel segment 110a, the wall thickness of the first channel segment 110a, for example, the wall thickness D1a, needs to be large enough. This makes it difficult to reduce the stacking thickness D2a of the first channel segment 110a and the microphone assembly 03, failing to meet the requirement of a thinner and lighter tablet 1.

[0072] Figure 2B This diagram illustrates the structure of a housing assembly in which a pickup channel 100b is formed in the flat panel 1 in some other technical solutions. For ease of observation, Figure 2B The path of pickup channel 100b is shown in the dashed line. (Reference) Figure 2B In some other technical solutions, the flat panel 1 also includes a channel bracket 11b. A portion of the pickup channel 100b is located in the middle frame 10b, and another portion is located in the channel bracket 11b.

[0073] Specifically, the first support portion 101b of the middle frame 10b supports the channel bracket 11b. The channel bracket 11b has a first channel segment 110b. The second support portion 101b of the middle frame 10b has a second channel segment 120b. The first channel segment 110b and the second channel segment 120b constitute the pickup channel 100b.

[0074] Since the first channel segment 110b is formed on the channel support 11b (e.g., injection molding), the wall thickness of the first channel segment 110b, for example, the wall thickness D1b, is still difficult to reduce in order to ensure the machinability of the first channel segment 110b. Furthermore, in order for the position of the first channel segment 110b to match the second channel segment 120b and to communicate with the microphone assembly 03, the overall thickness D3b of the channel support 11b is also relatively large. Therefore, the stacked thickness D2b of the first channel segment 110b and the microphone assembly 03 is difficult to reduce, failing to meet the requirement for a thinner and lighter tablet 1.

[0075] To address the aforementioned issues, the housing assembly of this application includes a mid-frame (as an example of a main body) and a cover plate. A first groove is formed on the mid-frame, and the cover plate covers the first groove, thereby forming a first channel segment together with the mid-frame. The cover plate can be used to form part of the channel wall of the first channel segment, and the mid-frame can be used to form another part of the channel wall of the first channel segment. Instead of drilling or injection molding the first channel segment on the cover plate, the thickness of the cover plate can be set as small as possible without considering the machinability of the first channel segment. This effectively reduces the wall thickness of the first channel segment, thereby reducing the stacking thickness of the first channel segment and the microphone assembly, achieving a thinner and lighter design for the flat panel. The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0076] Figures 3A to 3D A partial structural schematic diagram of the plate 1 in an embodiment of this application is shown, wherein, Figure 3A 3B is a three-dimensional view of part of the structure of plate 1, and 3B is an exploded view of part of the structure of plate 1. Figure 3C For flat plate 1 along Figure 3A Sectional view of section AA in the middle. Figure 3D For the shell 01 along Figure 3A Cross-sectional view of section AA. (Reference) Figure 3C and Figure 3D and combined Figure 3A and Figure 3B The housing assembly 01 includes a middle frame 10 and a cover plate 20.

[0077] The middle frame 10 includes a first support portion 101 and a second support portion 102. The first support portion 101 is similar to a plate-like structure and is used to support functional devices inside the tablet 1, such as the microphone assembly 03. The second support portion 102 is connected to the side of the first support portion 101. The second support portion 102 is used to support the display screen 02 to form the receiving cavity 05 of the tablet 1. It is understood that the first support portion 101 and the second support portion 102 can be integrally formed or separately formed and then assembled together to form an integral structure; this application does not limit this. The first support portion 101 is located inside the tablet 1, that is, after the tablet 1 is assembled, the user cannot observe or touch the first support portion 101; the outer surface 1021 of the second support portion 102 is part of the appearance surface of the tablet 1 (e.g., the side), that is, after the tablet 1 is assembled, the user can observe and touch the surface 1021 of the second support portion 102.

[0078] The cover plate 20 is disposed on the first support portion 101 of the middle frame 10, thereby forming a first channel segment 110 together with the first support portion 101 of the middle frame 10. Exemplarily, the extending direction of the first channel segment 110 intersects the Z direction, for example... Figure 3C and Figure 3D In the example shown, the first channel segment 110 extends in the Y direction.

[0079] Specifically, Figure 4A and Figure 4B This illustration shows a portion of the structure in which the frame 10 and the cover plate 20 mate in an embodiment of this application. Figure 4A This is an assembly drawing of the middle frame 10 and the cover plate 20. Figure 4B This is an exploded view of the middle frame 10 and the cover plate 20.

[0080] refer to Figure 4A and Figure 4B and combined Figure 3D A first groove 103 is provided on the middle frame 10. The opening direction of the first groove 103 faces the Z direction. The first groove 103 is jointly formed by a first support portion 101 and a second support portion 102. The bottom wall and a portion of the side wall of the first groove 103 are formed by at least a portion of the first support portion 101 of the middle frame 103, and the other portion of the side wall of the first groove 103 is formed by at least a portion of the second support portion 102 of the middle frame 10.

[0081] A cover plate 20 covers the opening of the first groove 103. Specifically, the cover plate 20 includes a first edge portion 210 and a second edge portion 220. The first edge portion 210 is similarly U-shaped, and the second edge portion 220 is similarly I-shaped, forming a U-shaped structure together. The first edge portion 210 of the cover plate 20 covers the first support portion 101, and the second edge portion 220 of the cover plate 20 covers the second support portion 102. Alternatively, it can be understood that one end of the cover plate 20 covers the second support portion 102, and the remaining portion of the cover plate 20 covers the first support portion 101. Thus, the cover plate 20 and the first groove 103 together form the first channel segment 110.

[0082] At least a portion of the cover plate 20 constitutes a first channel wall 111 of the first channel segment 110. For example, the first channel wall 111 is the middle portion of the cover plate 20 that is jointly surrounded by a first edge portion 210 and a second edge portion 220. At least a portion of the first support portion 101 of the middle frame 10 constitutes a second channel wall 112 of the first channel segment 110. For example, the second channel wall 112 is the bottom wall of the first groove 103. The first channel wall 111 and the second channel wall 112 are arranged opposite to each other and spaced apart along the Z direction. That is, the first channel wall 111 and the second channel wall 112 are arranged face-to-face in the Z direction, the projections of the first channel wall 111 and the second channel wall 112 along the Z direction at least partially overlap, and the first channel wall 111 and the second channel wall 112 have a gap in the Z direction, rather than being in contact. It can be understood that the area between the first channel wall 111 and the second channel wall 112 is used to form the first channel segment 110. Alternatively, along the Z direction, the orthographic projection area of ​​the first channel segment 110 in the YZ plane is located between the orthographic projection area of ​​the first channel wall 111 in the YZ plane and the orthographic projection area of ​​the second channel wall 112 in the YZ plane.

[0083] The aforementioned housing assembly 01 utilizes the middle frame 10 and the cover plate 20 to jointly form the first channel segment 110, eliminating the need to process the channel segment on the cover plate 20 (e.g., injection molding, drilling, etc.) before assembling it with the middle frame 10. Therefore, the thickness design of the cover plate 20 does not need to consider the manufacturability of the channel segment. For example, compared to the wall thickness D1a of the first channel segment 110a and the wall thickness D1b of the first channel segment 110b, the thickness D1 of the cover plate 20 can be set as small as possible, thereby effectively reducing the wall thickness of the first channel wall 111, and consequently reducing the stacking thickness D2 of the first channel segment 110 and the microphone assembly 03, achieving a thinner and lighter design for the tablet 1. It can be understood that the wall thickness of the first channel wall 111 is equal to the thickness D1 of the cover plate 20.

[0084] In some embodiments of this application, the thickness D1 of the cover plate 20 can be 0.2mm to 0.3mm, for example, 0.2mm, 0.21mm, 0.22mm, 0.23mm, etc. That is, the wall thickness of the first channel wall 111 can be 0.2mm to 0.3mm. In this way, the stacking thickness D2 of the first channel segment 110 and the microphone assembly 03 can be effectively reduced, thereby achieving a thinner and lighter design for the tablet 1.

[0085] In some embodiments of this application, the middle frame 10 can be made of metal or plastic. This ensures that the middle frame 10 has sufficient support strength. When the middle frame 10 is made of metal, the first groove 103 can be formed on the middle frame 10 by methods such as milling, laser cutting, or machining (e.g., drilling, CNC machining). When the middle frame 10 is made of plastic, the first groove 103 can be formed during the injection molding process of the middle frame 10.

[0086] Continue reading Figure 4B In some embodiments of this application, a second groove 104 is provided on the second support portion 102. The opening of the second groove 104 faces the cover plate 20. The second edge portion 220 of the cover plate 20 extends into the second groove 104 and covers the groove wall of the second groove 104.

[0087] Figure 5 This illustration shows an assembly diagram of the second groove 104 and the second edge portion 220 of the cover plate 20 in an embodiment of this application, wherein... Figure 5 for Figure 3C A magnified view of a portion of region S1. For easier observation, Figure 5 The area filled with dots shows the inner cavity of the second groove 104. (Reference) Figure 5 and combined Figure 4B The second groove 104 can be a semi-closed groove, that is, the cross-sectional shape of the second groove 104 is U-shaped, and its opening faces the cover plate 20. It can be understood that in this application, the cross-section of each component refers to a plane perpendicular to the component's extension direction, and the cross-sectional shape refers to the shape obtained after the component is cut along the cross-section. For example, if the second groove 104 extends along the X direction, the cross-section of the second groove 104 refers to a plane perpendicular to the X direction, or in other words, the cross-section of the second groove 104 is parallel to the YZ plane.

[0088] In this design, the inner surfaces of each wall of the second groove 104 are the surfaces facing the second groove 104, requiring other components to extend into the interior of the second groove 104 to contact the inner surfaces of each wall. Conversely, the outer surfaces of each wall of the second groove 104 are the surfaces facing away from the second groove 104, allowing other components to contact the outer surfaces of each wall without extending into the interior of the second groove 104. For example, the inner surface of side wall 1041 faces the second groove 104, and the outer surface of side wall 1041 faces away from the second groove 104. The second edge portion 220 of the cover plate 20 extends into the interior of the second groove 104 and covers the inner surface of side wall 1041. The inner surface of side wall 1042 faces the second groove 104, and the outer surface of side wall 1042 faces away from the second groove 104. The display screen 02 is located outside the second groove 104 and covers the outer surface of side wall 1042.

[0089] Because the inner surface of the sidewall 1041 of the second groove 104 has a length component along the Y direction, the sidewall 1041 of the second groove 104 can provide support force along the Z direction for the second edge portion 220 of the cover plate 20, thereby further improving the stability of the cover plate 20 installation. Furthermore, in the subsequent sealing process, when the cover plate 20 is subjected to a pressing force from the bracket 50 along the Z direction, it is easier for it to fit tightly against the inner surface of the sidewall 1041, thereby ensuring good sealing between the second support portion 102 and the cover plate 20 and preventing sound leakage. To ensure the continuity of the description, the specific sealing method will be described in detail later; please refer to [link / reference needed]. Figure 15 And related descriptions, let's continue with the following. Figure 5 An exemplary structure of the second groove 104 is described.

[0090] Continue reading Figure 5 The outer surface of the sidewall 1042 of the second groove 104 also has a length component along the Y direction. Therefore, the sidewall 1042 of the second groove 104 can provide support force along the Z direction for the display screen 02, preventing the display screen 02 from denting inward at the second groove 104 when subjected to external force. Furthermore, the sidewall 1042 of the second groove 104 can also increase the contact area between the second support portion 102 and the display screen 02, thereby effectively improving the installation stability of the display screen 02.

[0091] In some embodiments of this application, the inner surface of the sidewall 1041 of the second groove 104 is similar in shape to the second edge portion 220 of the cover plate 20, so as to better fit with the second edge portion 220 of the cover plate 20, thereby improving the support effect of the sidewall 1041 on the second edge portion 220.

[0092] For example Figure 5In the example shown, the second edge portion 220 of the cover plate 20 is inclined relative to the XY plane (i.e., the plane perpendicular to the Z direction). Correspondingly, the inner surface of the sidewall 1041 of the second groove 104 is an inclined surface relative to the XY plane, wherein the inner surface of the sidewall 1041 is the surface of the sidewall 1041 facing the second edge portion 220 of the cover plate 20. Alternatively, the second edge portion 220 of the cover plate 20 can also be placed parallel to the XY plane, and correspondingly, the inner surface of the sidewall 1041 of the second groove 104 is a horizontal surface parallel to the XY plane. Furthermore, the second edge portion 220 of the cover plate 20 can also be a curved surface, and correspondingly, the inner surface of the sidewall 1041 of the second groove 104 can also be a curved surface, and the curvature of both is the same.

[0093] In some embodiments of this application, the outer surface of the sidewall 1042 of the second groove 104 is a horizontal plane parallel to the XY plane. In this way, the sidewall 1042 of the second groove can better provide support for the display screen 02 in the Z direction, thereby improving the stability of the display screen 02 installation.

[0094] It is understood that the shape of the second groove 104 can be varied and is not limited to the U-shaped semi-closed groove in the above embodiment. As long as it can meet the installation requirements of the cover plate 20 without affecting the installation of the display screen 02, it is acceptable.

[0095] For example, Figure 6A and Figure 6B An exemplary structure of a second groove 104 in an embodiment of this application is shown, wherein, Figure 6A This is a three-dimensional view of the second groove 104. Figure 6B This is a schematic diagram showing the assembly of the second groove 104 and the second edge portion 220 of the cover plate 20. For ease of observation, Figure 6B The area filled with dots shows the inner cavity of the second groove 104. (Reference) Figure 6A and Figure 6B The second groove 104 is a semi-open groove with an L-shaped cross-section and its opening faces the cover plate 20.

[0096] The second edge portion 220 of the cover plate 20 covers the inner surface of the sidewall 1041 of the second recess 104. The inner surface of the sidewall 1041 has a length component along the Y direction, which can provide support force along the Z direction for the second edge portion 220 of the cover plate 20. The display screen 02 covers the outer surface of the sidewall 1042 of the second recess 104. The outer surface of the sidewall 1042 is parallel to the XY plane, which can provide support force along the Z direction for the display screen 02.

[0097] For example, Figure 7A and Figure 7B This invention illustrates another exemplary structure of the second groove 104 in an embodiment of the present application, wherein, Figure 7A This is a three-dimensional view of the second groove 104. Figure 7B This is a schematic diagram showing the assembly of the second groove 104 and the second edge portion 220 of the cover plate 20. For ease of observation, Figure 7B The area filled with dots shows the inner cavity of the second groove 104. (Reference) Figure 7A and Figure 7B The second groove 104 can also be an open groove, and the cross-section of the second groove 104 is trapezoidal.

[0098] The second edge portion 220 of the cover plate 20 covers the inner surface of the groove wall 1043 of the second groove 104. The inner surface of the groove wall 1043 has a length component along the Y direction, which can provide support force along the Z direction for the second edge portion 220 of the cover plate 20. The display screen 02 covers the outer surface of the groove wall 1043 of the second groove 104. The outer surface of the groove wall 1043 is parallel to the XY plane, which can provide support force along the Z direction for the display screen 02.

[0099] It is understood that the inner surface of the second edge portion 220 supporting the cover plate 20 and the outer surface supporting the display screen 02 in the second groove 104 described above can be surfaces with different groove walls or surfaces with the same groove wall; this application does not impose any restrictions on this. For example, Figure 5 , Figure 6A and Figure 6B In the example shown, the inner surface of the sidewall 1041 of the second groove 104 is used to support the second edge portion 220 of the cover plate 20, and the outer surface of the sidewall 1042 of the second groove 104 is used to support the display screen 02. Figure 7A and Figure 7B In the example shown, the inner surface of the groove wall 1043 of the second groove 104 is used to support the second edge portion 220 of the cover plate 20, and the outer surface of the groove wall 1043 of the second groove 104 is used to support the display screen 02.

[0100] Continue reading Figure 4B and combined Figure 3C and Figure 3DIn order to enable the first channel segment 110 to communicate with the outside of the plate 1, in some embodiments of this application, a second channel segment 120 is also provided on the second support portion 102 of the middle frame 10. The second channel segment 120 penetrates the side wall of the first groove 103, or in other words, the second channel segment 120 penetrates the solid portion of the second support portion 102 that forms the side wall of the first groove 103. The inlet 121 of the second channel segment 120 communicates with the outer surface 1021 of the second support portion 102. Alternatively, the inlet 121 of the second channel segment 120 is formed on the outer surface 1021 of the second support portion 102. It is understood that after the plate 1 is assembled, the user can directly observe the inlet 121 of the second channel segment 120 from the outer surface 1021 of the second support portion 102. The outlet 122 of the second channel segment 120 communicates with the first channel segment 110. It is understood that the outlet 122 of the second channel segment 120 is located inside the plate 1. In other words, after the tablet 1 is assembled, the user cannot observe the outlet 122 of the second channel segment 120.

[0101] In this way, the first channel segment 110 can be connected to the outside of the tablet 1 through the second channel segment 120. Sound emitted from a sound source located outside the tablet 1 can enter the second channel segment 120 through the inlet 121, and then be transmitted to the first channel segment 110 through the outlet 122 of the second channel segment 120, where it can be picked up by the microphone assembly 03, thus realizing the sound pickup function of the microphone assembly 03. It can be understood that the first channel segment 110 and the second channel segment 120 together constitute the sound pickup channel 100.

[0102] Since the entrance 121 of the second channel segment 120 can be directly observed by the user, it is necessary to arrange the position of the entrance 121 of the second channel segment 120 in a reasonable manner to ensure the aesthetics and refinement of the tablet 1.

[0103] Figure 8 This illustration shows an exemplary configuration of the inlet 121 of the second channel segment 120 in the flat plate 1 according to an embodiment of this application. (See reference...) Figure 8 and combined Figure 3C and Figure 3D In some embodiments of this application, the inlet 121 of the second channel segment 120 overlaps with the center P of the outer surface 1021 of the second support portion 102 along the Z direction. For example, the inlet 121 of the second channel segment 120 is circular in shape, and its center overlaps with the center P of the outer surface 1021 along the Z direction.

[0104] In this way, it can be ensured that the position of the entrance 121 of the second channel segment 120 is not too high or too low. When the user observes the outer surface 1021, the entrance 121 of the second channel segment 120 is in a relatively symmetrical position visually, thereby effectively improving the refinement and aesthetics of the tablet 1.

[0105] refer to Figure 5 and combined Figure 8 , Figure 3C and Figure 3D In some embodiments of this application, when the inlet 121 of the second channel segment 120 overlaps with the center P of the outer surface 1021 of the second support portion 102 along the Z direction, the second channel segment 120 can be inclined relative to the Y direction. Specifically, along the Z direction, the inlet 121 of the second channel segment 120 is further away from the second channel wall 112 than the outlet 122 of the second channel segment 120. Exemplarily, the extension direction of the second channel segment 120 can be the N direction, which intersects the Y direction.

[0106] In this way, without increasing the stacking thickness D2 of the first channel segment 110 and the microphone assembly 03, interference between the second channel segment 120 and the second edge portion 220 of the cover plate 20 can be avoided. This ensures that the sidewall 1041 of the second groove 104 is thick enough to provide sufficient support for the second edge portion 220 of the cover plate 20. Furthermore, the sidewall 1041 of the second groove 104 also forms part of the channel wall of the second channel segment 120; therefore, sufficient wall thickness of the sidewall 1041 of the second groove 104 also helps ensure the machinability of the second channel segment 120.

[0107] Continue reading Figure 5 To further avoid interference between the second channel segment 120 and the second edge portion 220 of the cover plate 20, in some embodiments of this application, the second edge portion 220 of the cover plate 20 is inclined relative to the extending direction of the second channel wall 112. Specifically, along the Z-direction, the first end 221 of the second edge portion 220 is further away from the second channel wall 112 than the second end 222 of the second edge portion 220. The second end 222 is the end of the second edge portion 220 connected to the first channel wall 111, and the first end 221 is the end opposite to the second end 222 along the extending direction of the cover plate 20. That is, along the extending direction of the cover plate 20, the first end 221 is further away from the first channel wall 111 than the second end 222. Exemplarily, the direction from the first end 221 to the second end 222 of the second edge portion 220 can be the N-direction.

[0108] The following describes several exemplary structures of the cover plate 20 with reference to the accompanying drawings, wherein the second edge portion 220 of the cover plate 20 is inclined relative to the extending direction of the second channel wall 112.

[0109] In some feasible embodiments, the cover plate 20 includes two planar plates, one of which is arranged parallel to the XY plane and the other is arranged at an angle relative to the XY plane.

[0110] Specifically, Figure 9 An exemplary structure of the cover plate 20 in an embodiment of this application is shown. (See reference...) Figure 9 and combined Figure 5 In some embodiments of this application, the cover plate 20 includes a first plate 20A and a second plate 20B. The first plate 20A and the second plate 20B are connected, and the second plate 20B is inclined relative to the first plate 20A in a direction away from the second channel wall 112. That is, the extending direction of the second plate 20B intersects the extending direction of the first plate 20A, and the angle between the extending direction of the second plate 20B and the extending direction of the second channel wall 112 is greater than the angle between the extending direction of the first plate 20A and the extending direction of the second channel wall 112. For example, Figure 9 In the example shown, the first plate 20A extends in the Y direction, the second plate 20B extends in the N direction, and the second channel wall 112 extends in the Y direction. The angle between the extension direction of the first plate 20A and the extension direction of the second channel wall 112 is 0°, and the angle between the extension direction of the second plate 20B and the extension direction of the second channel wall 112 is greater than 0°.

[0111] The edge of the first plate 20A is fixedly connected to the first support portion 101. The microphone assembly 03 is mounted on the side of the first plate 20A facing away from the first channel segment 110. Since the first plate 20A is horizontally arranged along the Y direction, it can better provide support for the microphone assembly 03 along the Z direction, ensuring the stability of the microphone assembly 03 during installation.

[0112] One edge of the second plate 20B is fixedly connected to the first support portion 110, and the other edge is fixedly connected to the second support portion 120. The other edge of the second plate 20B is the second edge portion 220 of the cover plate 20, that is, the second plate 20B is fixedly connected to the second support portion 102 through the second edge portion 220 of the cover plate 20.

[0113] Since the extension direction of the second plate 20B is the N direction, the direction from the first end 221 to the second end 222 of the second edge portion 220 is also the N direction. This effectively avoids interference between the second edge portion 220 and the second channel segment 120, ensuring that the wall thickness of the sidewall 1041 of the second groove 104 is sufficiently thick, thereby guaranteeing that the sidewall 1041 of the second groove 104 has sufficient support strength to support the second edge portion 220 of the cover plate 20.

[0114] In addition, the area enclosed by the first plate 20A and the second channel wall 112 forms the first portion 110A of the first channel segment 110, and the area enclosed by the second plate 20B and the second channel wall 120 forms the second portion 110B of the first channel segment 110. Since the extension direction of the second plate 20B is the N direction, the cross-sectional area of ​​the second portion 110B gradually increases from the end closer to the first portion 110A to the end farther away from the first portion 110A, making the second portion 110B generally resemble a trumpet shape. This increases the space of the first channel segment 110 to meet the size design requirements of the first channel segment 110 in various application scenarios. At the same time, the second portion 110B can share some thickness space with the microphone assembly 03, thus not adding extra thickness, which is beneficial for the thinner and lighter design of the tablet 1.

[0115] In some embodiments of this application, the direction from the first end 221 to the second end 222 of the second edge portion 220 can be parallel to the extension direction of the second channel segment 120. For example, the direction from the first end 221 to the second end 222 of the second edge portion 220 and the extension direction of the second channel segment 120 are both in the N direction. In this way, the inner surface of the sidewall 1041 of the second groove 104 and the outer surface of the sidewall 1041 of the second groove 104 can be set as two parallel surfaces, thereby making the wall thickness of the sidewall 1041 of the second groove 104 uniform and reducing stress concentration.

[0116] In some other embodiments, the extension direction of the second plate 20B may also intersect with the extension direction of the second channel segment 120. This application does not impose specific restrictions on this, as long as it is ensured that there is no interference between the second edge portion 220 and the second channel segment 120.

[0117] In some embodiments of this application, the connection between the first plate 20A and the second plate 20B can be rounded to reduce stress concentration and improve the aesthetics and refinement of the cover plate 20.

[0118] In other feasible options, the plate in cover 20 can also be a curved plate.

[0119] For example, Figure 10 An exemplary structure two of the cover plate 20 in an embodiment of this application is shown. (See reference...) Figure 10 In some embodiments, the second plate 20B of the cover plate 20 is a curved plate. Exemplarily, the curved surface may be oriented towards the first channel segment 110 (e.g., Figure 10The concave arc surface (as shown in the M direction) extends in the N1 direction of the second plate 20B, which is inclined relative to the extension direction of the second channel wall 112. Therefore, the second edge portion 220 is inclined relative to the extension direction of the second channel wall 112, effectively preventing interference between the second edge portion 220 and the second channel segment 120.

[0120] In some other feasible options, cover plate 20 may also include a greater number of plates.

[0121] For example, Figure 11 An exemplary structure three of the cover plate 20 in an embodiment of this application is shown. (See reference...) Figure 11 In some embodiments, the cover plate 20 includes three plates: a first plate 20A', a second plate 20B', and a third plate 20C'. The first plate 20A' and the second plate 20B' are connected by the third plate 20C'. The first plate 20A' extends in the Y direction, the second plate 20B' extends in the N direction, and the third plate 20C' extends in the Z direction, making the cover plate 20 generally Z-shaped.

[0122] The first plate 20A' supports the microphone assembly 03, and the first plate 20A' and the third plate 20C' are respectively fixedly connected to the first support portion 101. The edge portion of the second plate 20B' includes a second edge portion 220, and is fixedly connected to the second support portion 102 through the second edge portion 220.

[0123] Since the extension direction of the second plate 20B' is the N direction, the direction from the first end 221 to the second end 222 of the second edge portion 220 is also the N direction. In this way, the second edge portion 220 can be inclined relative to the extension direction of the second channel wall 112, thereby effectively avoiding interference between the second edge portion 220 and the second channel segment 120.

[0124] In other feasible solutions, the cover plate 20 may also include a single plate, that is, the cover plate 20 extends along a single plane, rather than different plates of the cover plate 20 extending along different planes, as described above. Figure 9 In the example shown, the first plate 20A extends along the XY plane, and the second plate 20B extends along the plane containing the X and N directions (abbreviated as XN plane).

[0125] For example, Figure 12 An exemplary structure four of the cover plate 20 in an embodiment of this application is shown. (See reference...) Figure 12In some embodiments, the cover plate 20 extends along the plane containing the X and N2 directions (hereinafter referred to as the XN2 plane). The N2 direction is inclined relative to the Y direction in a direction away from the second channel wall 112. Thus, the second edge portion 220 extends along the N2 direction, that is, the second edge portion 220 is inclined relative to the extension direction of the second channel wall 112, thereby effectively avoiding interference between the second edge portion 220 and the second channel segment 120.

[0126] In some implementations, the cover plate 20 can be a planar plate, for example, the cover plate 20 can be parallel to the XN2 plane. In other alternative implementations, the cover plate 20 can also be a curved plate, for example, the cover plate 20 extends along the XN2 plane and is slightly concave towards the first channel segment 110, or slightly convex towards the opposite direction of the first channel segment 110.

[0127] It is understood that this application does not specifically limit the shape of the cover plate 20, and any cover plate 20 that can avoid interference between the second edge portion 220 and the second channel segment 120 is within the protection scope of this application.

[0128] In some embodiments of this application, the cross-sectional area at different locations in the pickup channel 100 may be different. For example, Figure 9 In the example shown, the cross-sectional area of ​​the first channel segment 110 is larger than that of the second channel segment 120. The cross-sectional area of ​​the second part 110B of the first channel segment 110 gradually increases from the end closer to the first part 110A to the end farther away from the first part 110A, making the second part 110B generally resemble a trumpet shape. The cross-sectional area is the same at different locations in the first part 110A of the first channel segment 110.

[0129] In other alternative embodiments, the cross-sectional area at different locations in the pickup channel 100 may be the same, and this application does not specifically limit this.

[0130] In some embodiments of this application, the cross-sectional shape at different locations in the pickup channel 100 may be different. In other alternative embodiments, the cross-sectional shape at different locations in the pickup channel 100 may also be the same, and this application does not specifically limit this.

[0131] In some embodiments of this application, the cross-sectional shape of the pickup channel 100 can be at least one of regular shapes such as rectangle, circle, triangle, trapezoid, and pentagon. In other alternative embodiments, the cross-sectional shape of the pickup channel 100 can also be an irregular shape, which is not specifically limited in this application.

[0132] Continue reading Figures 3B to 3DTo enable communication between the pickup channels 100 and the microphone assembly 03 located on opposite sides of the cover plate 20, in some embodiments of this application, a through hole 200 is provided on the cover plate 20. The through hole 200 penetrates the first channel wall 111, thereby communicating with the first channel segment 110 of the pickup channel 100. In this way, sound emitted from a sound source located outside the plate 1 can be transmitted sequentially through the second channel segment 120 of the pickup channel 100, the first channel segment 110 of the pickup channel 100, and the through hole 200, and finally to the microphone assembly 03, thereby realizing the sound pickup function of the microphone assembly 03.

[0133] In some embodiments of this application, the shape of the through hole 200 can be at least one of regular shapes such as rectangle, circle, triangle, trapezoid, and pentagon. In other alternative embodiments, the shape of the through hole 200 can also be an irregular shape, which is not specifically limited in this application.

[0134] In some embodiments of this application, the cover plate 20 is a rigid plate with a certain strength, thereby preventing the first channel 110 from easily deforming, while also providing good support for the microphone assembly 03. For example, in some implementations, the cover plate 20 can be a metal sheet, such as a steel sheet, copper sheet, aluminum sheet, etc. Alternatively, in other implementations, the cover plate 20 can also be other non-metallic sheets, such as plastic sheets, Mylar sheets, etc., and this application does not specifically limit this.

[0135] Continue reading Figure 3B and Figure 3C In some embodiments of this application, a first sealing component 30 is provided at the connection between the middle frame 10 and the cover plate 20. The first sealing component 30 can improve the sealing between the middle frame 10 and the cover plate 20, thereby preventing sound leakage during the transmission from the pickup channel 100 to the through hole 200, and thus improving the sound pickup effect of the microphone component 03.

[0136] refer to Figure 3B and combined Figure 4A and Figure 4B In some embodiments of this application, the orthographic projection area of ​​the first sealing component 30 in the XY plane (as an example of the first plane) is located outside the orthographic projection area of ​​the first channel wall 111 in the XY plane, thereby preventing the first sealing component 30 from obscuring the first channel wall 111.

[0137] In some embodiments of this application, the shape of the first sealing component 30 is similar to the shape of the structure formed by the first edge portion 210 and the second edge portion 220 of the cover plate 20. That is, the orthographic projection area of ​​the first sealing component 30 in the XY plane coincides with the orthographic projection area of ​​the structure formed by the first edge portion 210 and the second edge portion 220 in the XY plane. Alternatively, by scaling down the orthographic projection area of ​​the structure formed by the first edge portion 210 and the second edge portion 220 in the XY plane, it can coincide with the orthographic projection area of ​​the first sealing component 30 in the XY plane. This ensures good sealing at all connections between the middle frame 10 and the cover plate 20.

[0138] Figure 13 An exemplary structure of the first sealing assembly 30 in an embodiment of this application is shown. (Reference) Figure 13 and combined Figure 3B and Figure 3C In some embodiments of this application, the first sealing component 30 includes foam 31. Foam 31 can achieve flexible fit between the middle frame 10 and the cover plate 20, fully filling the installation gap between the middle frame 10 and the cover plate 20, thereby playing a sealing role and improving sealing reliability.

[0139] In some embodiments of this application, adhesive backing 32A and adhesive backing 32B are respectively provided on two opposite surfaces of the foam 31 along the Z direction. The foam 31 can be bonded to the middle frame 10 and the cover plate 20 through the adhesive backing 32A and adhesive backing 32B, thereby achieving a fixed connection between the cover plate 20 and the middle frame 10. In this way, there is no need to set other structural components to fix the cover plate 20 and the middle frame 10, effectively reducing the number of unnecessary parts and making the assembly of the cover plate 20 and the middle frame 10 simpler and more convenient.

[0140] In other embodiments, the middle frame 10 and the cover plate 20 can also be fixedly connected by other means, such as snap-fit, fastener connection, etc., which are not specifically limited in this application.

[0141] Continue reading Figure 3B and Figure 3C In some embodiments of this application, a second sealing component 40 is provided at the connection between the cover plate 20 and the microphone assembly 03. The second sealing component 40 can improve the sealing between the cover plate 20 and the microphone assembly 03, thereby preventing sound leakage during transmission from the through hole 200 to the microphone assembly 03, and thus improving the sound pickup effect of the microphone assembly 03. The second sealing component 40 differs from the first sealing component 30 in that the second sealing component 40 includes not only foam and adhesive backing, but also a dustproof mesh. Figure 14 An exploded view of the second sealing assembly 40 in an embodiment of this application is shown. (Reference) Figure 14 and combined Figure 3B and Figure 3C The second sealing assembly 40 includes foam 41 and dustproof mesh 42. The foam 41 and dustproof mesh 42 are arranged opposite each other along the Z direction.

[0142] The foam 41 allows for a flexible fit between the cover plate 20 and the microphone assembly 03, fully filling the installation gap between them to achieve a seal and improve sealing reliability. The dustproof mesh 42 has a fine mesh structure that effectively prevents dust, fine particles, and other debris from entering the microphone assembly 03, thus avoiding blockage or damage and extending its service life.

[0143] In some embodiments of this application, the orthographic projection area of ​​the foam 41 in the XY plane can be located outside the orthographic projection area of ​​the through hole 300 in the XY plane, thereby avoiding obstruction of the through hole 300.

[0144] In some embodiments of this application, foam 41 can be bonded and fixed to dustproof mesh 42 and microphone assembly 03 by adhesive (not shown), and dustproof mesh 42 can also be bonded and fixed to cover plate 20 by adhesive, so that cover plate 20 can be fixedly connected to microphone assembly 03.

[0145] Continue reading Figure 3B and Figure 3C In some embodiments of this application, the tablet 1 further includes a bracket 50. The bracket 50 presses the cover plate 20 and the microphone assembly 03 onto the middle frame 10 and is fixedly connected to the middle frame 10.

[0146] Figure 15 An exemplary configuration of the bracket 50 in an embodiment of this application is shown. (See reference...) Figure 15 and combined Figure 3B and Figure 3C Because the bracket 50 can provide pressure along the Z-direction to the cover plate 20, the microphone assembly 03, the middle frame 10, the first sealing assembly 30 between the cover plate 20 and the microphone assembly 03, and the second sealing assembly 40 between the cover plate 20 and the microphone assembly 03, the middle frame 10, the cover plate 20, and the microphone assembly 03 can fit tightly together, and both the first sealing assembly 30 and the second sealing assembly 40 are under compression. Thus, the first sealing assembly 30 can more fully fill the installation gap between the middle frame 10 and the cover plate 20, and the second sealing assembly 40 can more fully fill the installation gap between the cover plate 20 and the microphone assembly 03, thereby achieving a reliable seal between the pickup channel 100, the through hole 200, and the microphone assembly 03.

[0147] In some embodiments of this application, the microphone assembly 03 can be first attached to the bracket 50 using adhesive 60, and then the bracket 50 can be installed on the middle frame 10. The bracket 50 can serve a positioning function, allowing the microphone assembly 03 to be installed more accurately in the correct position and to fit tightly against the cover plate 20.

[0148] In some embodiments of this application, the bracket 50 and the middle frame 10 are fixedly connected by screws 70. The screws 70 are sequentially inserted into the bracket 50 and the middle frame 10 along the Z-direction, and the tail of the screw 70 is fixed to the middle frame 10 by threads. In other embodiments, the bracket 50 and the middle frame 10 can also be fixedly connected by other methods, such as other fastener connections (e.g., bolt connections), adhesive bonding, snap-fitting, etc. This application does not limit this, as long as the bracket 50 can achieve the aforementioned clamping effect.
