Description

Technical Field

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

[0002] A microphone is an electronic device that converts sound signals into electrical signals and is widely used in electronic devices such as mobile phones and tablets. In recent years, audio and video media functions such as video recording, live streaming, video calls, and WeChat calls have become mainstream applications for electronic devices. When users shoot videos, they want to capture sound from the direction the video is shooting to reduce ambient noise; when users make video calls or WeChat calls, they want to clearly hear the other party's voice; when users live stream, they want to capture sound from the direction the video is shooting, as well as the voice of the main person being filmed. Therefore, microphones are usually placed near the camera module of electronic devices to achieve functions such as call noise reduction and sound focusing.

[0003] In related technologies, in order to introduce external sound into the microphone to achieve the conversion of sound and electrical signals, a pickup port is usually opened on the housing component of the electronic device. A pickup channel is provided between the pickup port and the microphone. The sound signal (such as sound wave) from outside the electronic device enters the pickup channel from the pickup port and is transmitted to the microphone through the pickup channel, where the microphone picks up the sound signal.

[0004] The microphone port is located on the back of the housing assembly, and its placement significantly impacts the appearance of electronic devices. Currently, microphone ports are typically located on the back of the camera trim, with the microphone channel also situated on the trim. The microphones are stacked between the trim and the motherboard, occupying stacking space in the thickness direction and hindering the design towards a slimmer, lighter form factor. One solution is to create an opening in the lens of the camera trim; however, the microphone port's position is still limited by the aesthetic design, and the microphone's placement remains somewhat restricted. Alternatively, placing the microphone port on the periphery of the trim offers better concealment and increased flexibility, but due to space constraints, it often requires multiple maneuvers to avoid internal components, lengthening the microphone channel and affecting sound pickup. Furthermore, as electronic devices become increasingly powerful, motherboards contain more and more components, and with advancements in imaging technology, camera modules are growing larger. The motherboard and camera module continuously encroach on microphone mounting space, further restricting microphone placement. In an era focused on slimmer, lighter electronic devices, the current solution of stacking microphones between the camera trim and the motherboard is no longer suitable. Some existing technologies improve the position of the microphone port and the path of the microphone channel in an effort to leave enough space for the microphone installation, but most of them require increasing the length of the microphone channel, which makes the microphone's pickup path longer and greatly reduces the sound reception effect.

[0005] Therefore, existing technology cannot balance microphone installation space and sound pickup performance. Summary of the Invention

[0006] The housing assembly and electronic device provided in this application embodiment solve the problem that the prior art cannot balance the installation space and sound reception effect of the microphone.

[0007] A first aspect of this application provides a housing assembly, including:

[0008] The housing has mounting holes.

[0009] A camera trim piece, which extends through a mounting hole in the housing and at least partially protrudes relative to the back of the housing.

[0010] The pickup channel has a pickup port located on the back of the housing assembly at one end, and the other end is used to connect to a microphone so that sound waves from the back of the housing assembly enter the pickup channel through the pickup port and are transmitted to the microphone through the pickup channel.

[0011] Furthermore, the sound pickup channel includes a sound pickup through-hole, which is disposed on the portion of the housing located around the mounting hole and extends from the back side of the housing to the front side; wherein the back side of the housing is disposed opposite to the front side, and the back side of the housing and the outer surface of the portion of the camera trim protruding from the back side of the housing constitute at least a portion of the back side of the housing assembly.

[0012] The housing assembly provided in this application embodiment has a camera decorative piece fixedly connected to the mounting hole of the housing. A sound pickup channel is provided on the housing assembly, allowing external sound to enter through the pickup port and be transmitted to the microphone along the channel for sound pickup. The sound pickup channel includes a pickup through-hole, which is located on the portion of the housing surrounding the mounting hole. This means a portion of the sound pickup channel is located on the housing and around the mounting hole. In this way, the microphone can be installed below the pickup through-hole (on the side opposite to the pickup port), i.e., around the mounting hole. The camera module is located inside the mounting hole. Installing the microphone around the mounting hole allows for offset placement from the camera module, eliminating the need to stack the microphone between the camera module and the motherboard, thus providing more installation space. Furthermore, the elimination of the need for functional component avoidance design within the camera decorative piece allows for a simpler path design for the entire sound pickup channel, shortening the pickup path length and improving pickup stability and microphone sound pickup quality.

[0013] Therefore, the housing assembly provided in this application embodiment can balance the microphone's installation space and sound reception effect.

[0014] In one possible implementation, the camera trim includes an outer trim having an outer skirt that surrounds the periphery of the mounting hole and is disposed on the back of the portion of the housing located around the mounting hole.

[0015] The housing assembly also includes a first waterproof seal surrounding the periphery of the mounting hole. The first waterproof seal is disposed between the back of the portion of the housing located around the mounting hole and the outer skirt facing the housing surface, thereby creating a sealed connection between the back of the housing and the outer trim.

[0016] The sound pickup hole is located on the outer periphery of the first waterproof seal.

[0017] Using the above method, the camera trim and the housing are sealed together by a first waterproof sealant. Correspondingly, the first waterproof sealant can be arranged in the area around the mounting hole on the housing and between the outer skirt of the trim to ensure the waterproof sealing effect of the housing assembly. The microphone hole is located on the outside of the first waterproof sealant. Under the premise of ensuring the waterproof sealing effect between the camera trim and the housing is intact, the microphone channel can still directly penetrate the housing without the need for an obstacle avoidance design for the waterproof sealant, thus obtaining the shortest path for the microphone channel.

[0018] In one possible implementation, the first waterproof sealant is set as a sealant layer.

[0019] By adopting the above solution, the camera decorative part and the housing meet the waterproof sealing requirements of the housing assembly. The camera decorative part is glued to the housing of the electronic device by the first waterproof sealant, which plays a fixing role and reduces the risk of the camera decorative part falling off the housing.

[0020] In one possible implementation, the area of ​​the housing located around the mounting hole, having a pickup through-hole, is configured as an extension protruding toward the center of the mounting hole relative to other areas.

[0021] The sealing area of ​​the first waterproof seal corresponding to the extension platform is configured as a recessed structure that is recessed toward the center of the mounting hole relative to other sealing areas, and the recessed structure forms a clearance space covering the pickup through hole, the pickup channel including at least a portion of the clearance space.

[0022] In the above-described design, an extension platform protruding towards the center of the mounting hole is provided around the mounting hole on the housing, with the microphone pickup hole passing through the extension platform. The extension platform can be positioned anywhere on the outer periphery of the mounting hole to accommodate a microphone, allowing for greater freedom in microphone placement within the housing assembly and increasing the flexibility of microphone placement design. Correspondingly, a first waterproof seal forms a concave structure along the outer periphery of the extension platform, ensuring the integrity of the waterproof seal between the camera trim and the housing at the microphone placement location. This reduces the risk of external liquids entering the housing assembly's internal space through the gap between the camera trim and the housing. Furthermore, a waterproof and breathable structure is typically provided in the channel between the pickup port and the microphone, ensuring that external sound can enter normally through the pickup port of the pickup channel and be transmitted to the microphone for sound pickup while preventing external liquids from entering the housing assembly's internal space through the microphone pickup hole.

[0023] In one possible implementation, the pickup channel further includes a decorative channel formed on the outer trim, one end of which forms a pickup port, and the other end is located on the surface of the outer trim facing the back of the housing and communicates with the pickup through hole. Furthermore, the orthographic projection of the decorative channel onto the back of the housing is located on the outer periphery of the first waterproof seal.

[0024] When the housing assembly has clearance space and the housing has an extension platform, the other end of the decorative element channel communicates with the sound pickup through-hole through the clearance space. Part or all of the orthographic projection of the decorative element channel onto the back of the housing is located on the extension platform of the housing.

[0025] The above solution includes a decorative channel on the outer decorative part. The orthographic projection of the decorative channel on the back of the housing is located outside the first waterproof seal. The decorative channel is directly connected to the pickup hole, which shortens the path of the pickup channel inside the outer decorative part, improves the pickup stability, and at the same time avoids the first waterproof seal from being interrupted by the pickup channel, ensuring the integrity of the waterproof seal of the housing assembly.

[0026] In one possible implementation, the pickup port is oriented in a direction perpendicular to the thickness direction of the housing assembly, and in the thickness direction of the housing assembly from the outer trim toward the housing, the pickup port is blocked by the end of the outer trim away from the housing.

[0027] With the above solution, the microphone is located on the periphery of the outer decorative part and is covered by the outer decorative part in the thickness direction of the housing assembly. In this way, the visible range of the microphone on the back of the housing assembly is reduced, achieving a certain degree of hiding effect, thereby improving the aesthetics of the appearance.

[0028] In one possible implementation, the channel portion containing the microphone in the decorative element channel is tilted towards the center of the camera decorative element on the side of the housing.

[0029] By adopting the above solution, the decorative channel connected to the microphone port is at least partially inclined toward the center of the camera decorative component on the side of the housing. The right angle is designed as an angle at the bend, which helps to shorten the length of the microphone channel and improve the microphone's sound pickup effect. On the other hand, it ensures the structural strength of the outer decorative component at the opening and improves the reliability of the product structure.

[0030] In one possible implementation, the housing assembly further includes a first seal that surrounds the outer periphery of the other end of the decorative element channel and the outer periphery of the pickup hole, and is sealed between the back of the housing and the outer decorative element.

[0031] When the housing assembly has clearance space and the housing has an extension platform, the first seal is sealed between the extension platform of the housing and the exterior trim and is located within the clearance space.

[0032] By adopting the above solution, the first seal ensures a sealed connection between the sound pickup hole on the housing and the camera decorative part, preventing sound waves from leaking at the connection between the camera decorative part and the housing, ensuring that the sound waves are effectively transmitted along a specific path, and achieving good sound pickup effect of the microphone.

[0033] In one possible implementation, the outer decorative element includes: a first decorative element and a second decorative element stacked and sealed together in the thickness direction of the housing assembly, an outer skirt formed on the second decorative element, the first decorative element located on the side of the second decorative element away from the housing, and the second decorative element protruding from the outer peripheral surface of the first decorative element in a plane perpendicular to the thickness direction of the housing assembly.

[0034] Furthermore, the microphone is located on the outer peripheral surface of the first decorative element and is positioned close to the outer surface of the second decorative element, with the microphone facing away from the center of the camera decorative element.

[0035] In one possible implementation, the camera trim also includes an inner trim, which includes an inner trim body and an inner skirt connected to the inner trim body. The inner skirt is fixedly and sealed to the front of the housing, and the inner trim body is fixedly connected to the outer trim.

[0036] The interior trim has a notch at the location corresponding to the microphone hole, which covers the microphone hole and is used to set up the microphone.

[0037] By adopting the above solution, one side surface of the housing assembly is fixed and sealed to the outer decorative part, and the other side surface of the housing is fixedly connected to the inner decorative part. The inner and outer decorative parts are also fixedly connected, which avoids or reduces the risk of the camera decorative part falling off the housing, improves the stability of the camera decorative part fixed to the housing, and thus improves the quality of the electronic device.

[0038] A second aspect of this application provides an electronic device including a housing assembly as provided in any of the above implementations, and a microphone assembly containing a microphone, the microphone assembly being sealed to the front of the housing and located in the area where the pickup hole is located in the portion surrounding the mounting hole.

[0039] The electronic device provided in this application embodiment has sufficient installation space for the microphone assembly, facilitating microphone placement. A sealed connection exists between the microphone assembly and the housing to prevent sound wave leakage and ensure optimal microphone reception.

[0040] In one possible implementation, the microphone assembly further includes a flexible circuit board module, which is fixed and electrically connected to the microphone and located between the microphone's circuit board and the front of the housing, with the side of the flexible circuit board module facing away from the microphone sealed to the front of the housing.

[0041] Furthermore, the flexible circuit board module is equipped with a microphone hole, one end of which is connected to the pickup hole, and the other end of which is connected to the microphone.

[0042] The electronic device also includes a bracket, which is disposed within the cavity of the housing assembly, and the microphone is fixed to the bracket via a flexible circuit board module.

[0043] With the above solution, the microphone is fixed and electrically connected to the flexible circuit board module to realize the transmission of electrical signals. The microphone is fixed to the bracket through the flexible circuit board module to prevent the microphone from falling out of the housing assembly, thereby improving the stability of microphone pickup.

[0082] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0083] Please see Figures 1-2 , Figure 1 This is a partial cross-sectional structural diagram of a housing assembly. Figure 2 This is a schematic diagram of a partial cross-sectional structure on the back of a housing assembly.

[0084] like Figure 1 , Figure 2 As shown, the housing assembly 100' includes a housing 110', a camera decorative piece 120', and a microphone channel 140'. The camera decorative piece 120' includes a first decorative piece 121' and a second decorative piece 122', which are fixed and sealed together by a first sealing member 151' and a second sealing member 152' to prevent external liquid from leaking into the camera decorative piece and damaging the electronic components inside the housing assembly 100'. The first decorative piece 121' has a camera hole 1211' for arranging and mounting a camera module for electronic equipment. The second decorative piece 122' is fixedly connected to the housing 110' by a third sealing member 153'. The housing assembly 100' also includes a light-transmitting lens 160', which is fixedly connected to the side of the first decorative piece 121' away from the housing 110' by an adhesive layer, allowing external light to enter the camera module to achieve photo and video recording functions.

[0085] The housing assembly 110' also includes a motherboard bracket 170' for securing electronic components inside the housing assembly 100' and supporting the housing. Figure 1 From this perspective, the motherboard is mounted below the 170' motherboard bracket, and the motherboard and... Figure 2 From the perspective of the circuit board module 190', it is electrically connected. A microphone 180' is mounted on the motherboard bracket 170' for audio-visual signal conversion. The microphone 180' is electrically connected to the circuit board module 190' and is fixedly connected to the motherboard bracket 170'. A sealing element 154' is provided between the microphone 180' and the camera trim 120' to ensure that external liquids do not penetrate into the housing assembly.

[0086] like Figure 1 , Figure 2As shown, the camera decorative piece 120' has a microphone port 130'. Sound waves from outside the housing assembly enter the microphone port 130' and are transmitted to the microphone 180' via the microphone channel 140' to achieve sound pickup. The microphone channel 140' includes two channels: a first channel 141' and a second channel 142'. The microphone port 130' is recessed on the first decorative piece 121' towards the center of the camera decorative piece 120' to form a first sub-channel 1411'. The second sub-channel 1412' partially extends through the first decorative piece 141' in the vertical direction directly opposite the microphone 180', connecting to the first sub-channel 1411'. The second channel 142' penetrates the sealing piece 154', with one end connected to the second sub-channel 1412' and the other end connected to the microphone hole 181' located on the microphone 180'.

[0087] With the increasing power of electronic devices, motherboards now contain more and more functional components. Furthermore, with advancements in imaging technology, camera modules in electronic devices are becoming larger and larger. The motherboard and camera module are constantly encroaching on microphone installation space, making microphone placement increasingly limited. Adjusting the microphone's installation space by modifying the pickup port position and pickup channel path often increases the length of the pickup channel, resulting in a longer microphone pickup path and affecting sound reception.

[0088] To address the aforementioned issues, this application provides a housing assembly and an electronic device. By providing a sound pickup hole on the housing, the microphone can be offset from the camera module, resulting in more installation space, effectively shortening the sound pickup path, and improving the microphone's sound pickup performance.

[0089] The electronic devices provided in this application include, but are not limited to, mobile phones, tablet computers, laptop computers, wearable electronic devices, etc. The embodiments of this application do not impose special restrictions on the specific form of the above-mentioned electronic devices. For ease of explanation, mobile phones are used as an example below.

[0090] Please see Figures 3-5 , Figure 3 This is a schematic diagram of the rear structure of the electronic device according to an embodiment of this application; Figure 4 This is a front view of the electronic device according to an embodiment of this application. Figure 5 This is an exploded structural diagram of the housing assembly in an embodiment of this application.

[0091] like Figures 3-5As shown, the electronic device 100 includes a housing assembly 300. In one possible implementation, the electronic device 100 further includes a display screen 200 mounted on the housing assembly 300. When a user uses the electronic device 100, the display screen 200 faces the user, and the surface of the housing assembly 300 facing away from the display screen 200 in the thickness direction Z of the electronic device is the back surface of the housing assembly 300. The display screen 200 can be an Organic Light-Emitting Diode (OLED) display screen, or a Liquid Crystal Display (LCD), etc., and this application does not limit this to any particular type.

[0092] like Figure 3 As shown, the housing assembly 300 includes a housing 310 and a camera trim 320. The housing 310 is provided with a mounting hole 311. The camera trim 320 passes through and is installed on the mounting hole 311 of the housing 310. The camera trim 320 protrudes at least partially relative to the housing 310.

[0093] The specific structure of the housing 310 is not limited; for example, it can be the mid-frame or back cover of the electronic device 100. The housing 310 has an internal space for supporting the display screen 200 and housing the electronic components of the electronic device 100, and also serves to protect the electronic device 100 and support the entire device. In one possible implementation, the housing 310 is the back cover of the electronic device 100. In this case, the electronic device 100 also includes a mid-frame (not shown in the figure), with the display screen 200 and housing 310 respectively fixedly mounted on both sides of the mid-frame. The housing 310 and the mid-frame surround each other to form the aforementioned internal space, and the bracket 500 mentioned below (see...) Figure 5 ), Motherboard 600 (see) Figure 5 All components are housed within this accommodating space, with the bracket 500 fixed to the middle plate of the mid-frame, and the main board 600 fixed between the bracket 500 and the middle plate of the mid-frame. In another possible implementation, the housing 310 can also be the mid-frame of the electronic device, in which case the middle plate of the mid-frame directly serves as the back cover of the electronic device.

[0094] Furthermore, the front and back sides of the housing 310 are positioned opposite each other. The outer surface of the housing 310 facing away from the user's operating surface is the back side of the housing 310, that is, the side surface facing away from the display screen in the thickness direction Z of the electronic device. The camera decorative piece 320 is used to fix and protect the camera module 71, and can also be used to decorate the camera module 71 to improve the aesthetic appearance of the electronic device. The portion of the outer surface of the camera decorative piece 320 protruding from the housing 310 and the back side of the housing 310 constitute at least a portion of the back side of the housing assembly 300. It should be noted that the camera decorative piece 320 may protrude entirely from the housing 310, or it may protrude partially from the housing 310 while the other part is hidden inside the housing 310; this application does not impose any limitations on this.

[0095] It should be noted that the specific materials of the housing 310 and the camera decorative part 320 are not limited. They can be metals, such as iron, steel, stainless steel, or aluminum, or non-metals, such as plastic, or a combination of metal and non-metal. The materials of the housing 310 and the camera decorative part 320 can be the same or different. They can be a one-piece structure or a separate structure. This application does not impose any restrictions on this.

[0096] like Figure 3 As shown, the electronic device 100 also includes a camera module 71, which is located inside the housing assembly 300 and is used to perform functions such as taking pictures and videos. The camera module 71 may include one or more cameras, each camera having a lens 72. The camera trim 320 is provided with a camera hole 321 corresponding to each lens 72, through which external light can enter the lens.

[0097] It should be noted that this application does not limit the layout of the camera module 71 or the shape of the lens 72 of each camera module 71; the accompanying drawings are for illustrative purposes only. In one possible implementation, the camera module 71 includes three cameras, and the camera decorative piece 320 is correspondingly provided with three camera holes 321. Each camera can be a depth-sensing camera, a telephoto / wide-angle camera, or a monochrome camera, etc., to meet the user's needs for shooting different scenes; this application does not impose any restrictions on this.

[0098] Furthermore, the electronic device 100 also includes a microphone assembly, which is used to collect external sound and convert the sound signal into an electrical signal. The electronic device 100 may include one or more microphone assemblies as needed. Each microphone assembly has a microphone, and different microphone assemblies perform different functions, working together to improve the call reception quality of the electronic device 100. Each microphone assembly is located within the internal cavity of the housing assembly 300. In one possible implementation, the microphone assembly of the electronic device 100 includes a main microphone assembly and a secondary microphone assembly. The main microphone assembly is located at the bottom of the electronic device 100, i.e., the end closest to the user's mouth when making a call, and is used for call and recording functions. The secondary microphone assembly is located at the top of the electronic device 100, i.e., the end furthest from the user's mouth during a call, and can assist in sound pickup and noise reduction during recording, video recording, and calls. It should be noted that this application does not limit the specific structure or arrangement of the main and secondary microphone assemblies; those skilled in the art can design the main and secondary microphone assemblies according to actual needs.

[0099] Please see Figures 6-7b , Figure 6 This is a partial side view of the electronic device according to an embodiment of this application; Figure 7a for Figure 6 A schematic diagram of the cross-sectional structure along the AA direction. Figure 7b This is a partial cross-sectional perspective view of the housing assembly in an embodiment of this application.

[0100] like Figure 5 As shown, the microphone assembly of the electronic device 100 includes a third microphone assembly, namely microphone assembly 400, which includes a microphone 410. The microphone assembly 400 is sealed to the front of the housing 310 and located in the area where the pickup through-hole 341 is located in the portion surrounding the mounting hole 311. The microphone assembly 400 is disposed around the camera module 71 and has functions such as auxiliary noise reduction and sound focusing. The electronic device 100 provided in this application embodiment has sufficient mounting space for the microphone assembly 400, facilitating the placement of the microphone 410. The microphone assembly 400 and the housing 310 are sealed together to prevent sound wave leakage and avoid affecting the microphone's sound pickup performance.

[0101] Furthermore, such as Figure 3 , Figure 6 , Figure 7aAs shown, the housing assembly 300 also has a sound pickup channel 340 inside. One end of the sound pickup channel 340 is a sound pickup port 330 located on the back of the housing 310, and the other end of the sound pickup channel 340 is used to connect to the microphone assembly 400, so that sound waves from the back of the housing assembly 300 enter the sound pickup channel 340 through the sound pickup port 330 and are transmitted to the microphone assembly 400 through the sound pickup channel 340. Alternatively, it can be understood that the sound pickup port 330 is the entrance to the sound pickup channel 340, and external sounds can enter the sound pickup channel 340 through the sound pickup port 330 and then be transmitted along the sound pickup channel 340 to the microphone 410 in the microphone assembly 400 to achieve sound pickup.

[0102] like Figures 5-7b As shown, the pickup channel 340 includes a pickup through hole 341, which is disposed in the portion of the housing 310 surrounding the mounting hole 311 and extends from the back of the housing 310 to the front.

[0103] The housing assembly 300 provided in this application embodiment has a camera decorative piece 320 fixedly connected to the mounting hole 311 of the housing 310. A sound pickup channel 340 is provided on the housing assembly 300. Sound from outside the housing assembly 300 can enter through the sound pickup port 330 of the sound pickup channel 340 and be transmitted along the sound pickup channel 340 to the microphone assembly 400 for sound pickup. The sound pickup channel 340 includes a sound pickup through-hole 341, which is located on the portion of the housing 310 surrounding the mounting hole 311. This can be understood as a portion of the sound pickup channel 340 being formed on the housing 310 and located around the mounting hole 311. In this way, the microphone 410 can be installed below the sound pickup through-hole 341 (on the side opposite to the sound pickup port 330), that is, around the mounting hole 311. The camera module 71 is located within the mounting hole 311. The microphone 410 is mounted around the mounting hole 311, allowing it to be offset from the camera module 71. This eliminates the need to stack the microphone 410 between the camera module 71 and the motherboard 600, thus providing more installation space. Furthermore, the elimination of the need for functional component avoidance design within the camera decorative piece 320 allows for a simpler path design in the entire sound pickup channel 340, shortening the sound pickup path length and improving sound pickup stability, resulting in higher sound pickup quality from the microphone 410.

[0104] Therefore, the housing assembly 300 and electronic device 100 provided in this application embodiment can take into account both the installation space and sound reception effect of the microphone 410.

[0105] Those skilled in the art will understand that the shapes of the pickup port 330 and the pickup channel 340 are not limited. The pickup port 330 can be circular, elliptical, oriented, irregular, etc., and any cross-section of the pickup channel 340 can be circular, elliptical, oriented, irregular, etc. The accompanying drawings are for illustrative purposes only. The inner wall surface of the pickup channel 340 can be a smooth surface or a rough surface, and this application does not impose any limitations on this. The specific extension path of the pickup channel 340 is not limited, and the specific location of the pickup port 330 on the back of the housing assembly 300 is not limited. For example, it can be located on the housing 310 or on the camera decorative piece 320. Several possible scenarios will be illustrated below with reference to the accompanying drawings.

[0106] Please see Figures 8a-8c , Figure 8a This is a schematic cross-sectional view of the pickup channel in the housing assembly of an embodiment of this application. Figure 1 , Figure 8b This is a schematic diagram of the pickup channel structure in the housing assembly of this application embodiment. Figure 2 , Figure 8c This is a schematic diagram of the pickup channel structure in the housing assembly of this application embodiment. Figure 3 .

[0107] like Figure 8a As shown, in one possible implementation, the microphone port 330 is located on the back of the housing 310. For example, the microphone port 330 can be positioned near the area surrounding the camera trim 320, which facilitates better sound pickup and recording from outside the electronic device 100 by the microphone 410. One end of the microphone through-hole 341 connects to the microphone port 330, and the other end connects to the microphone 410 of the microphone assembly 400. That is, when the microphone port 330 is located on the back of the housing 310, the microphone channel 340 only includes the microphone through-hole 341, thus minimizing the length of the microphone channel 340 and improving sound pickup. The microphone port 330 can be positioned near the camera trim 320, meaning that the opening of the microphone port 330, while exposed relative to the back of the housing 310, is further closer to the interior of the housing 310 to improve its concealment, thereby further enhancing the aesthetic appearance of the electronic device 100.

[0108] Those skilled in the art will understand that, in order to ensure the aesthetic appearance of the electronic device, the microphone 330 can be positioned on the camera decorative piece 320, for example... Figure 7a , Figure 8b , Figure 8c The scheme is shown below. The specific location of the microphone port 330 on the camera decorative part 320 is not limited. To facilitate understanding of the scheme, the structure of the camera decorative part 320 will be explained in detail below.

[0109] like Figure 5 , Figure 7a, Figure 7b As shown, in one possible implementation, the camera trim 320 includes an outer trim 322 having an outer skirt that surrounds the outer periphery of the mounting hole 311 and is disposed on the back side of the portion of the housing 310 located around the mounting hole 311. In another possible implementation, the camera trim 320 further includes an inner trim 323, which includes an inner trim body 3231 and an inner skirt 3232 adjoining the inner trim body 3231 (see reference). Figure 11 The inner skirt 3232 is fixedly and sealed to the front of the housing 310, and the inner decorative body 3231 is fixedly connected to the outer decorative part 322. Figure 7a As shown, the inner decorative element 323 has a notch at the position corresponding to the microphone hole 341, the notch covers the microphone hole 341 and is used to set the microphone 410. In the housing assembly 300, one side surface of the housing 310 is fixedly and sealed to the outer decorative element 322, and the other side surface of the housing 310 is fixedly connected to the inner decorative element 323. The inner decorative element 323 and the outer decorative element 322 are fixedly connected, which avoids or reduces the risk of the camera decorative element 320 falling off the housing 310, improves the stability of the camera decorative element 320 fixed to the housing 310, and thus improves the quality of the electronic device 100.

[0110] It should be noted that the structures of the outer decorative element 322 and the inner decorative element 323 are not limited. In one possible implementation, the outer decorative element 322 includes a first decorative element 3221 and a second decorative element 3222 stacked and sealed together in the thickness direction Z of the housing assembly 300. An outer skirt is formed on the second decorative element 3222. The first decorative element 3221 is located on the side of the second decorative element 3222 away from the housing 310, and the second decorative element 3222 protrudes from the outer peripheral surface of the first decorative element 3221 in a plane perpendicular to the thickness direction Z of the housing assembly 300.

[0111] The connection method between the first decorative component 3221 and the second decorative component 3222 is not limited. They can be bonded together by applying adhesive, using adhesive backing, or by welding to achieve a fixed and sealed connection. Alternatively, the first decorative component 3221 and the second decorative component 3222 can be designed as an integral structure; this application does not limit this. In one possible embodiment, the inner decorative component 323 and the outer decorative component 322 are connected by screws (see reference). Figure 11The interior trim 322 is fixedly connected to the housing 310 via partial adhesive application (not shown in the figure). Generally, six screw connections can be provided on the interior trim body 3231, with additional adhesive application at intervals for reinforcement. This further securely connects the exterior trim 322 to the housing 310, preventing the risk of the exterior trim 322 detaching from the housing 310. It is understood that this application does not limit the fixing method between the interior trim 323 and the exterior trim 322.

[0112] An adhesive element 390 is provided between the interior trim 323 and the housing 310 (see...) Figure 11 The adhesive 390 is located on the front of the housing 310 and is fixedly connected to the inner skirt 3232. The back of the housing 310 is provided with a first waterproof seal 350 for fixing the outer decorative part 322. It can be understood that the outer decorative part 322, the housing 310 and the inner decorative part 323 are fixedly connected by a sandwich layer through the first waterproof seal 350 and the adhesive 390. That is, at least part of the housing 310 is sandwiched between the inner skirt 3232 of the inner decorative part 323 and the outer skirt of the outer decorative part 322, which reduces the risk of the camera decorative part 320 falling off the housing 310 and improves the stability of the camera decorative part 320 fixed to the housing 310, thereby improving the quality of the electronic device 100.

[0113] The inner decorative component 323 can be a metal decorative component, and the outer decorative component 322 can also be a metal decorative component. The materials of the metal decorative components include, but are not limited to, iron, steel, stainless steel, or aluminum. Alternatively, the inner decorative component 323 can be a plastic decorative component, and the outer decorative component 322 can also be a plastic decorative component. By combining the inner decorative component 323 and the outer decorative component 322, the assembly strength and stability of the electronic device 100 can be improved, while also contributing to the aesthetic appeal of the electronic device 100. Those skilled in the art will understand that, in order to meet the aesthetic requirements of the appearance while maintaining the metallic texture, the outer decorative component 322 or the inner decorative component 323 can be manufactured using a nano-injection molding process, directly injecting plastic onto the metal surface to achieve integrated molding of metal and plastic, reducing processing steps, lowering production costs, and reducing the weight of the camera decorative bracket 320, extending its service life, and improving the overall quality of the electronic device. Therefore, this application does not limit the processing technology of the camera decorative component 320.

[0114] like Figure 7a , Figure 7bAs shown, in one possible implementation, the microphone 330 is disposed on the outer peripheral surface of the first decorative member 3221 and located near the outer surface of the second decorative member 3222, with the microphone 330 facing away from the center of the camera decorative member 320. Specifically, in one possible implementation, the microphone 330 is positioned perpendicular to the thickness direction Z of the housing assembly 300, and in the thickness direction Z of the housing assembly 300, from the outer decorative member 322 towards the housing 310, the microphone 330 is obscured by the end of the outer decorative member 322 away from the housing 310. The microphone 330 is located on the peripheral side of the outer decorative member 322 and is obscured by the outer decorative member 322 in the thickness direction Z of the housing assembly 300. This reduces the visible range of the microphone 330 on the back of the housing assembly 300, achieving a certain degree of concealment and thus improving the aesthetic appearance.

[0115] like Figure 7a As shown, in one possible implementation, the pickup channel 340 further includes a decorative channel 342 formed on the outer decorative part 322. One end of the decorative channel 342 forms a pickup port 330, and the other end is located on the surface of the outer decorative part 322 facing the back of the housing 310 and communicates with the pickup through hole 341. After external sound enters through the pickup port 330, it sequentially enters the microphone assembly 400 along the decorative channel 342 and the pickup through hole 341.

[0116] like Figure 7a As shown, in one possible implementation, the decorative element channel 342, which includes a channel portion containing a microphone port 330, is inclined towards the center of the camera decorative element 320 near the housing 310. Alternatively, the decorative element channel 342, connected to the microphone port 330, is at least partially inclined towards the center of the camera decorative element 320 near the housing 310, with the right angle at the bend being designed as an angle. This shortens the length of the microphone channel 340, improving the sound pickup effect of the microphone 410. Furthermore, it ensures the structural strength of the outer decorative element 322 at the opening, enhancing the reliability of the product structure. The decorative element channel 342 can be entirely inclined or only partially inclined; this application does not limit this. The extension direction of the decorative element channel 342 can be a straight line, a curved line, or a broken line; this application does not limit this.

[0117] The microphone port 330 can also be located in other positions on the camera trim 320. For example... Figure 8b As shown, in one possible implementation, the pickup port 330 is located on the back of the first decorative element 3221, and the opening of the pickup port 330 faces the thickness direction Z parallel to the housing assembly 300. Figure 8cAs shown, in one possible implementation, the pickup port 330 can also be located on the back of the second decorative element 3222, with the opening of the pickup port 330 facing the thickness direction Z parallel to the housing assembly 300.

[0118] Those skilled in the art will understand that the housing assembly 300 needs to have some waterproof structure at the location of the pickup channel 340 to ensure the airtightness of the electronic device. Several possible solutions are illustrated below with reference to the accompanying drawings.

[0119] Please see Figures 9 to 11 , Figure 9 This is a partial structural diagram of the housing assembly in an embodiment of this application; Figure 10 This is a partially exploded structural diagram of the housing assembly and camera decorative part in the electronic device according to an embodiment of this application; Figure 11 This is a cross-sectional structural diagram of the camera decorative component in an electronic device according to an embodiment of this application.

[0120] like Figure 5 , Figure 7a , Figures 9 to 11 As shown, in one possible implementation, the housing assembly 300 further includes a first waterproof seal 350 surrounding the mounting hole 311. The first waterproof seal 350 is disposed between the back side of the portion of the housing 310 surrounding the mounting hole 311 and the outer skirt facing the surface of the housing 310 (i.e., the first waterproof seal 350 is disposed between the outer decorative piece 322 and the back side of the housing 310), thus sealing the back side of the housing 310 with the outer decorative piece 322. The microphone hole 341 is located on the outer periphery of the first waterproof seal 350. The camera decorative piece 320 and the housing 310 are sealed together using the first waterproof seal 350. Correspondingly, the first waterproof seal 350 can be arranged between the area surrounding the mounting hole 311 on the housing 310 and the outer skirt of the outer decorative piece 322 to ensure the waterproof sealing effect of the housing assembly 300. The microphone hole 341 is located on the outside of the first waterproof seal 350. Under the premise of ensuring the waterproof seal between the camera decorative part 320 and the housing 310 is intact, the microphone channel 340 can still directly penetrate the housing 310 without the need for an obstacle avoidance design for the waterproof seal, thus obtaining the shortest path for the microphone channel 340.

[0121] The specific form of the first waterproof seal 350 is not limited; for example, it can be sealant, rubber ring, etc. In one possible implementation, the first waterproof seal 350 is set as a sealant layer. While meeting the waterproof sealing requirements of the housing assembly 300, the camera decorative part 320 is also glued to the housing 310 of the electronic device via the first waterproof seal 350, thus fixing it and reducing the risk of the camera decorative part 320 detaching from the housing 310. For example, the sealant layer can be formed by a dispensing process. Dispensing is a process used in the industrial production of electronic products. By applying, potting, or dripping white glue, red glue, UV glue, etc., between various components, it reinforces, seals, and insulates the components, providing moisture protection and thermal conductivity for the functional components within the housing assembly 300, thereby maximizing the protection of these components and making the quality of the electronic device 100 more stable. In addition, after reinforcement with dispensing, it also has the effect of shielding electromagnetic interference, preventing deformation caused by external forces that could lead to malfunction of the electronic device 100. The sealant layer can also be adhesive backing, which is a type of adhesive that bonds various components together, thus preventing problems such as components falling off or moving. Adhesive backing can also be applied to the back of the electronic device 100, effectively preventing wear and damage to the back of the housing assembly 300, thereby extending the service life of the electronic device 100.

[0122] like Figure 7a , Figures 9 to 11 As shown, in one possible implementation, the portion of the housing 310 surrounding the mounting hole 311, having the microphone hole 341, is configured as an extension platform 312 protruding towards the center of the mounting hole 311 relative to other areas. The sealing area of ​​the first waterproof seal 350 corresponding to the extension platform 312 is configured as a recessed structure recessed towards the center of the mounting hole 311 relative to other sealing areas, and the recessed structure forms a clearance space covering the microphone hole 341, the microphone channel 340 further including at least a portion of the clearance space.

[0123] This can be understood as follows: a mounting platform is provided around the mounting hole 311. The mounting platform is formed by a recess on the side of the housing 310 facing from the back of the housing 310 towards the front of the housing 310, and is used to house the first waterproof seal 350. The side of the first waterproof seal 350 away from the center of the mounting hole 311 is the outer side of the first waterproof seal 350. An extension platform 312 is located around the mounting hole 311 and protrudes towards the center of the mounting hole 311, and is used to house the microphone 410. The microphone 410 is sealed and connected to the front of the housing 310 by a waterproof sealing layer. A first seal 360 is provided on the back of the housing 310, and the first seal 360 is located around the microphone 410. It should be noted that the extension platform 312 can be formed at any position around the mounting hole 311 and protrude towards the center of the mounting hole 311 according to the flexible arrangement of the microphone 410. This application does not impose any restrictions on this.

[0124] An extension platform 312 protruding towards the center of the mounting hole 311 is provided around the mounting hole 311 on the housing 310, and a microphone pickup hole 341 passes through the extension platform 312. The extension platform 312 can be set at any position on the outer periphery of the mounting hole 311 for arranging and connecting the microphone 410, making the placement of the microphone 410 inside the housing assembly 300 more flexible and increasing the design flexibility of the microphone 410 position. Correspondingly, the first waterproof seal 350 forms a concave structure along the outer periphery of the extension platform 312, that is, at the position where the microphone 410 is arranged, the integrity of the waterproof seal between the camera decorative part 320 and the housing 310 is also ensured, reducing the risk of external liquid entering the internal space of the housing assembly 300 through the gap between the camera decorative part 320 and the housing 310. Furthermore, a waterproof and breathable structure is typically provided in the channel between the pickup port 330 and the microphone 410. This ensures that external sound from the housing assembly 300 can enter normally through the pickup port 330 of the pickup channel 340 and be transmitted to the microphone 410 along the pickup channel 340 to achieve sound pickup, while preventing external liquid from entering the internal space of the housing assembly 300 through the pickup through-hole 341.

[0125] In one possible implementation, the orthographic projection of the decorative element channel 342 onto the back of the housing 310 is located on the outer periphery of the first waterproof seal 350. The other end of the decorative element channel 342 is connected to the sound pickup hole 341 through a clearance space. Part or all of the orthographic projection of the decorative element channel 342 onto the back of the housing 310 is located on the extension platform 312 of the housing 310, which shortens the path of the sound pickup channel 340 inside the outer decorative element 322, improves sound pickup stability, and at the same time avoids the first waterproof seal 350 being interrupted by the sound pickup channel 340, ensuring the integrity of the waterproof seal of the electronic device.

[0126] like Figure 7a , Figure 7bAs shown, in one possible implementation, the housing assembly 300 further includes a first seal 360. The first seal 360 surrounds the outer periphery of the other end of the decorative channel 342 and the outer periphery of the sound pickup hole 341 (i.e., between the outer decorative piece 322 and the front of the housing 310), and is sealed between the back of the housing 310 and the outer decorative piece 322. When the housing assembly 300 has a clearance space and the housing 310 has an extension platform 312, the first seal 360 is sealed between the extension platform 312 of the housing 310 and the outer decorative piece 322, and is located within the clearance space. The first seal 360 ensures a sealed connection between the sound pickup hole 341 on the housing 310 and the camera decorative piece 320, preventing sound waves from leaking at the connection between the camera decorative piece 320 and the housing 310, ensuring that sound waves propagate effectively along a specific path, and achieving good sound pickup performance of the microphone 410. The specific form of the first sealing element 360 is not limited, such as an adhesive layer, sealing ring, foam, etc., and can be achieved by dispensing adhesive and backing adhesive.

[0127] Optionally, the pickup channel 340 within the exterior trim 322 may also include multiple sequentially connected and interconnected sub-channels.

[0128] It should be noted that the specific structure and placement of the microphone assembly 400 are not limited. For example... Figure 5 , Figure 7a , Figure 10 As shown, the microphone assembly 400 also includes a flexible circuit board module 420, which is fixed and electrically connected to the microphone 410 and located between the circuit board of the microphone 410 and the front of the housing 310. The side of the flexible circuit board module 420 facing away from the microphone 410 is sealed to the front of the housing 310.

[0129] like Figure 10 As shown, in one possible implementation, the electronic device 100 further includes a bracket 500 disposed within the cavity of the housing assembly 300. The microphone 410 is fixed to the bracket 500 via a flexible circuit board module 420. The microphone 410 is fixed and electrically connected to the flexible circuit board module 420 to transmit electrical signals. The microphone 410 is fixed to the bracket 500 via the flexible circuit board module 420 to prevent it from falling out of the housing assembly 300, thus improving the stability of the microphone 410's sound pickup. The electronic device 100 may also omit the bracket 500; this application does not limit this. The method of sealing the flexible circuit board module 420 to the housing 310 is not limited; for example, it can be achieved through bonding, welding, or other methods.

[0130] In one possible implementation, the electronic device 100 further includes a motherboard 600. The motherboard 600 and the microphone 410 are respectively fixed to opposite sides of the bracket 500. The thickness of the microphone 410 in the thickness direction of the housing assembly 300 can be reused with the thickness of the electronic components between the camera decorative piece 320 and the bracket 500, which is beneficial for reducing the thickness of the electronic device 100. The microphone 410 is fixed to the bracket 500 via a flexible circuit board module 420, and the microphone 410 is electrically connected to the motherboard 600 via the flexible circuit board module 420. The flexible circuit board module 420 is located between the front of the housing 310 and the microphone 410 to enable the transmission of electrical signals in the microphone 410. Optionally, the microphone 410 can be soldered to the flexible circuit board module 420 using a soldering process, and the flexible circuit board module 420 can be fixed to the bracket 500 by adhesive. Those skilled in the art will understand that this application does not limit the fixing method between the microphone 410 and the flexible circuit board module 420, or between the flexible circuit board module 420 and the bracket 500.

[0131] In one possible implementation, the projection of the microphone 410 of the microphone assembly 400 onto the housing 300 along the thickness direction of the housing assembly 300 is located within the opening of the pickup hole 341. Alternatively, the pickup hole 341 can be understood as extending along a straight line parallel to the thickness direction of the housing assembly 300, with the microphone 410 located directly below the pickup hole 341. Opening a vertical hole in the thickness direction of the housing assembly 300 can effectively shorten the path of the pickup channel 340, ensuring the sound pickup effect of the microphone 410.

[0132] like Figure 7a , Figure 7b As shown, in one possible implementation, the microphone assembly 400 is provided with a waterproof and breathable membrane 372. The waterproof and breathable membrane 372 is fixed to a portion of the housing 310 around the pickup hole 341 by a waterproof sealing layer 370, preventing leakage of external liquids and protecting the microphone 410 from water, salt, and other corrosive liquids, thus extending the service life of the microphone 410. It is understood that this application does not limit the arrangement of the waterproof and breathable membrane 372. The waterproof and breathable membrane 372 not only serves to prevent dust, water, and air leakage, but also allows sound to pass through, ensuring that the sound quality is not affected. Exemplarily, the waterproof sealing layer 370 can be set as an adhesive layer or a sealing ring, implemented through processing methods such as back adhesive and dispensing; this application does not limit this.

[0133] In one possible implementation, a sealing foam 371 is provided between the flexible circuit board module 420 of the microphone assembly 400, the side facing away from the microphone 410, and the housing 310. The sealing foam 371 is disposed between the waterproof sealing layer 370 and the microphone assembly 400. In another possible implementation, the sealing foam 371 is sound-absorbing foam. Because sound-absorbing foam has a certain amount of compression deformation, it can be pressed tightly between the housing 310 and the microphone assembly 400 (for example, it can be pressed tightly between the front of the housing 310 and the flexible circuit board module 420 by the waterproof seal 370), preventing externally transmitted sound waves from leaking into the interior of the housing assembly 300, thus achieving good sealing and sound insulation effects. It is understood that those skilled in the art can design waterproof seals according to actual needs to ensure the sealing performance of the electronic device 100. This application does not limit the number or location of waterproof seals.

[0134] like Figure 10 As shown, in one possible implementation, the camera decorative element 320 further includes a light-transmitting layer 324. The light-transmitting layer 324 is installed on the side of the first decorative element 3221 facing away from the housing 310, and is used to cover the camera module 71 to prevent external debris, dust, and liquid from entering the camera decorative element 320, ensuring the airtightness of the electronic device 100. The light-transmitting layer 324 is made of a transparent material, such as glass. This application does not limit the material of the light-transmitting layer 324. In one possible embodiment, the microphone 330 is opened on the peripheral side of the camera decorative element 320. Neither the microphone 330 nor the microphone channel 340 is arranged on the light-transmitting layer 324, avoiding the need for processing the light-transmitting layer 324, thereby reducing the cost of the electronic device 100. At the same time, the microphone channel 340 extends from the side of the camera decorative element 320. When the light-transmitting layer 324 is installed on the camera decorative element 320, there is no need to align the microphone channel 340 through the through hole formed by the light-transmitting layer 324, reducing the installation time of the electronic device 100.

[0135] To better secure the lens, the light-transmitting layer 324 is fixed to the first decorative component 3221 via a light-transmitting adhesive layer 325. This adhesive layer can have pre-set openings for the arrangement of the camera module 71, allowing external optical fibers to enter the camera module 71 through the openings. The light-transmitting adhesive layer 325 can be an adhesive or a solid glue (such as double-sided tape), and this application does not limit it.

[0136] like Figure 10As shown, the outer decorative component 322 is fixed and sealed to the housing 310 by a first waterproof sealant 350. The processing technology and function of the first waterproof sealant 350 will not be elaborated here. The outer decorative component 322 includes a first decorative component 3221 and a second decorative component 3222 stacked together. The first decorative component 3221 is located on the side of the second decorative component 3222 away from the housing 310. The first decorative component 3221 and the second decorative component 3222 are fixedly connected by a second waterproof sealant 380 to prevent external liquid from leaking into the camera decorative component 320, ensuring the integrity of the overall waterproof seal. The second waterproof sealant 380 can be manufactured using methods such as adhesive application and backing adhesive.

[0137] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
