Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] Currently, electronic devices such as mobile phones usually have a microphone hole on the back, which is usually located on the lens. However, since users can easily come into contact with the lens when using electronic devices, the microphone hole on the lens is easily clogged by dirt and oil, which may cause the microphone hole to malfunction. Summary of the Invention

[0003] This application aims to provide an electronic device that solves the problem of microphone holes being easily blocked when they are opened on lenses.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides an electronic device, which includes:

[0006] Housing assembly;

[0007] Microphone assembly;

[0008] The decorative component assembly has a first through hole on its side and a first channel inside the decorative component assembly. One end of the first channel is connected to the first through hole. The decorative component assembly includes a first decorative component and a second decorative component stacked together. The first through hole is located between the first decorative component and the second decorative component. The first decorative component is connected to the housing assembly. The microphone assembly is located on the side of the first decorative component away from the second decorative component. The other end of the first channel is connected to the microphone assembly.

[0009] In embodiments of this application, a sealed first channel is formed inside the decorative component assembly. The first end of the first channel communicates with a first through-hole, allowing external sound waves to be introduced. The second end of the first channel extends to communicate with the acoustic inlet of the microphone assembly, thus forming a complete sound wave conduction path from the outside to the inside of the device. To ensure that sound waves are not interfered with during transmission and to meet the waterproof and dustproof requirements of the electronic device, the first and second decorative components are sealed together. This makes the first channel an independent cavity that communicates with the external environment but is isolated from other spaces inside the electronic device.

[0010] This embodiment efficiently utilizes the inherent double-layer structure space of the camera decorative ring area. By concealing the first through-hole within the interlayer gap of the decorative component, it avoids directly opening holes in prominent positions on the lens or decorative component of the electronic device, maintaining the simplicity of the back of the electronic device. Moreover, since the first through-hole is located on the side of the decorative component, it is not easily accessible to the user's hand, and the first through-hole is less likely to be blocked, thereby reducing the risk of failure of the first through-hole.

[0033] The following is combined with Figures 1-14 An electronic device according to an embodiment of the present invention is described.

[0034] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments of this application, an electronic device 100 is proposed. The electronic device 100 includes: a housing assembly 110, a microphone assembly 130, and a decorative component assembly 140. The decorative component assembly 140 has a first through hole 141 on its side and a first channel 142 inside the decorative component assembly 140. One end of the first channel 142 communicates with the first through hole 141. The decorative component assembly 140 includes a first decorative component 143 and a second decorative component 144 stacked together. The first through hole 141 is located between the first decorative component 143 and the second decorative component 144. The first decorative component 143 is connected to the housing assembly 110. The microphone assembly 130 is disposed on the side of the first decorative component 143 opposite to the second decorative component 144. The other end of the first channel 142 communicates with the microphone assembly 130.

[0035] The housing assembly 110 forms the structural framework of the electronic device 100, providing a mounting base and physical protection for internal components. The decorative component assembly 140 is located on the back of the electronic device 100. The decorative component assembly 140 is typically used to enclose and protect the camera module. A first through-hole 141 is provided on the side of the decorative component assembly 140; the first through-hole 141 is a sound inlet. The decorative component assembly 140 adopts a layered structure, comprising a first decorative element 143 and a second decorative element 144 that are joined together. In some embodiments of this application, the first through-hole 141 communicates with the external environment of the electronic device.

[0036] The housing assembly 110 serves as a basic structural component. The first decorative element 143 is directly or indirectly connected and fixed to the housing assembly 110, and the first decorative element 143 undertakes the main installation and positioning function. The second decorative element 144 is stacked on top of the first decorative element 143, and the first decorative element 143 and the second decorative element 144 together form a complete decorative ring-shaped appearance. In this embodiment, the first through hole 141 is located on the side of the interlayer between the first decorative element 143 and the second decorative element 144. This concealed design minimizes the disruption of the appearance integrity of the electronic device 100 caused by the first through hole 141, making the first through hole 141 more visually concealed and aesthetically pleasing.

[0037] A sealed first channel 142 is formed inside the decorative component assembly 140. The first channel 142 is a sound inlet channel, with its first end connected to the first through hole 141, allowing external sound waves to be introduced. The second end of the first channel 142 extends to connect with the acoustic inlet of the microphone assembly 130, thus forming a complete sound wave conduction path from the outside to the inside of the device. To ensure that the sound waves are not disturbed during transmission and to meet the waterproof and dustproof requirements of the electronic device 100, the first decorative component 143 and the second decorative component 144 are sealed together. This makes the first channel 142 an independent cavity that is connected to the external environment but isolated from other spaces inside the electronic device 100.

[0038] This embodiment efficiently utilizes the inherent double-layer structure space of the camera decorative ring area. By hiding the first through-hole 141 in the interlayer gap of the decorative component 140, it avoids directly opening holes in prominent positions on the lens 160 or decorative component 140 of the electronic device 100, maintaining the simplicity of the back of the electronic device 100. Furthermore, since the first through-hole 141 is located on the side of the decorative component 140, it is less likely for the user's hand to come into contact with it. Dust, water stains, foreign objects, and other impurities can easily fall into the first through-hole 141 and cause blockage. Therefore, the first through-hole 141 is less prone to blockage, thereby reducing the risk of failure. In some embodiments of this application, the microphone component 130 may be a speaker, microphone, receiver, pickup, or other similar device.

[0039] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in one possible embodiment, the first channel 142 includes a first sub-channel 145 and a second sub-channel 146.

[0040] The second decorative element 144 is annular, and includes an annular portion 1441 and an extension portion 1442, the extension portion 1442 being disposed circumferentially on the annular portion 1441. Figure 8 The arrow at point C points between the two ends, and the extension 1442 protrudes from the inner periphery of the annular portion 1441.

[0041] The first decorative element 143 includes a body portion 1431, a first groove 148 is provided on the side of the body portion 1431 facing the second decorative element 144, and a second groove 149 is provided on the side of the extension portion 1442 facing the first decorative element 143. The first groove 148 and the second groove 149 together form a first sub-channel 145.

[0042] The second sub-channel 146 is disposed inside the main body 1431. One end of the first sub-channel 145 is connected to the first through hole 141, and the other end of the first sub-channel 145 is connected to the second sub-channel 146.

[0043] The second decorative element 144 has a ring-shaped structure and surrounds the camera or other optical components. The second decorative element 144 includes a ring-shaped portion 1441 and an extension portion 1442. The ring-shaped portion 1441 is annular, and the extension portion 1442 is integrally formed or fixedly connected to the inner ring surface of the ring-shaped portion 1441. A second groove 149 is machined on the surface of the extension portion 1442 facing the first decorative element 143. Correspondingly, a first groove 148 is provided on the surface of the main body portion 1431 of the first decorative element 143 facing the extension portion 1442. When the first decorative element 143 and the second decorative element 144 are stacked and assembled, the first groove 148 on the extension portion 1442 and the second groove 149 on the first decorative element 143 are spatially aligned, together forming a cavity with a specific cross-sectional shape. This cavity constitutes the first sub-channel 145. The second sub-channel 146 of the first channel 142 is disposed inside the solid of the first decorative member 143. One end of the second sub-channel 146 communicates with the first sub-channel 145, and the other end of the second sub-channel 146 extends to connect with the inlet of the microphone assembly 130. In some embodiments of this application, the annular portion 1441 and the extension portion 1442 can be integrally formed. In other embodiments of this application, the annular portion 1441 and the extension portion 1442 can be separate structures connected to each other. In some embodiments of this application, the shapes of the first groove 148 and the second groove 149 can be arbitrary. That is, along the extension direction of the first groove 148 and the second groove 149, their widths and depths can be inconsistent. For example, the first groove 148 includes a first groove segment and a second groove segment, wherein the width of the first groove segment is greater than the width of the second groove segment, and the depth of the first groove segment is greater than the depth of the second groove segment. The first groove segment and the second groove segment are radially distributed along the first decorative member 143, and the first groove segment is disposed at the edge of the body portion 1431 of the first decorative member 143.

[0044] The extension 1442 is not simply a decorative structure, but a functional acoustic bridge. It begins on the inner annular surface of the ring-shaped portion 1441 and extends and protrudes locally towards the central axis of the annular region. To cooperate with the extension 1442 in constructing a sound wave path, the structure of the first decorative element 143 at the corresponding position is designed to fit the extension 1442. The extension 1442 acts as a "connecting bridge," bridging the spatial distance between the actual physical location of the microphone assembly 130 and the first through-hole 141 on the sidewall of the decorative element assembly 140, effectively guiding and transmitting sound waves from the first through-hole 141 on the sidewall to a direction closer to the mounting position of the internal microphone assembly 130. Subsequently, the sound waves enter the second sub-channel 146 through the end of the first sub-channel 145.

[0045] By providing an extension 1442 on the inner circumferential surface of the second decorative element 144, a bridge channel is cleverly designed inside the decorative element assembly 140 within the limited thickness space of the electronic device 100, successfully solving the connection problem between two holes (the first through hole 141 and the entrance of the microphone assembly 130) that are not on the same axis. This approach improves the flexibility of the microphone assembly 130 layout, so that the microphone assembly 130 no longer has to be forcibly placed below the opening on the side wall of the decorative element assembly 140, but can be placed in a more reasonable and space-saving position according to the motherboard layout and space constraints, thereby freeing up valuable space for other important components inside the electronic device 100.

[0046] Combination Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible embodiment, the body portion 1431 is provided with a third groove 153 and a fourth groove 151 on the side facing the second decorative member 144.

[0047] The third groove 153 extends circumferentially along the body portion 1431. A portion of the first groove 148 is disposed between the two circumferential ends of the third groove 153. The fourth groove 151 surrounds another portion of the first groove 148. The annular portion 1441 engages with the third groove 153. In some embodiments of this application, the third groove 153 extends circumferentially along the edge of the first decorative member 143. Radially along the first decorative member 143, the third groove 153 is closer to the edge of the first decorative member 143 than the fourth groove 151. That is, radially from the first decorative member 143, the first decorative member 143 is sequentially provided with the fourth groove 151 and the third groove 153, with the third groove 153 disposed at the edge of the body portion 1431 of the first decorative member 143. In some embodiments of this application, the first segment of the first groove 148 is located between the two circumferential ends of the third groove 153, and the second segment of the first groove 148 is surrounded by the fourth groove 151. The width of the first segment is greater than the width of the second segment, and the depth of the first segment is greater than the depth of the second segment.

[0048] The extension 1442 includes a sub-fitting portion 1443 surrounding the second groove 149. Part of the sub-fitting portion 1443 engages with the fourth groove 151, and another part of the sub-fitting portion 1443 engages with the third groove 153. In some embodiments of this application, the sub-fitting portion 1443 has an annular structure, including two ends and a middle portion connecting the ends. Its two circumferentially oriented ends respectively engage with the third groove 153, and its middle portion engages with the fourth groove 151.

[0049] The extension 1442 includes a sub-fitting portion 1443, which surrounds the second groove 149. A fourth groove 151 in the body portion 1431 surrounds the first groove. A portion of the sub-fitting portion 1443 is in a sealing fit with the fourth groove 151; that is, the fourth groove 151 is a dispensing groove, and sealant can be filled into the fourth groove 151 to seal the fourth groove 151 and the sub-fitting portion 1443 through dispensing.

[0050] The fourth groove 151 provides a space for adhesive in the subsequent dispensing process. When the first decorative part 143 and the second decorative part 144 are assembled, a portion of the sub-fitting part 1443 will be embedded in or near the fourth groove 151. At this time, sealant is injected into the fourth groove 151 through a dispensing device. Under capillary action and pressure, the sealant fills the tiny gap between the inner wall of the fourth groove 151 and the sub-fitting part 1443, and then cures to form a continuous and reliable sealing ring, preventing sound leakage from the side of the first sub-channel 145, thereby avoiding sound pressure loss or crosstalk with other external cavities, and ensuring that sound waves are effectively confined within the first sub-channel 145. Moreover, the dispensing forms a waterproof and dustproof barrier, which can effectively prevent external moisture and contaminants from penetrating the interior of the first sub-channel 145 through the joint surface of the sub-fitting part 1443 and the main body 1431, which helps the electronic device 100 meet the waterproof requirements.

[0051] To establish a larger perimeter sealing barrier over the decorative component assembly 140, the annular portion 1441 mates with the third groove 153, and the corresponding area on the first decorative component 143 is sealed with adhesive. This circumferential sealing structure functions to form a closed sealing ring around the outer edge of the decorative component assembly 140, constituting a barrier to prevent external liquids and dust from entering the interior of the electronic device 100, thereby effectively protecting the internal area of ​​the decorative component assembly 140.

[0052] The shape of the third groove 153 is adapted to the shape of the annular portion 1441. During assembly, sealant is applied to the third groove 153. When the annular portion 1441 is pressed against the first decorative element 143, the sealant is filled in the gap between the third groove 153 and the annular portion 1441 and cures, forming a continuous and strong circumferential sealing ring. This sealing ring, together with the sealing structure formed around the fourth groove 151, constitutes a two-layer sealing network. The inner seal (fourth groove 151) is mainly responsible for isolating and sealing the first sub-channel 145 itself, preventing sound leakage and local intrusion. The outer seal (third groove 153) is responsible for isolating the entire decorative element assembly 140 from the internal environment of the device. Even if a seal in one place fails slightly due to long-term use or accidental events, the other seal can still provide effective protection, greatly improving the ability of the electronic device 100 to cope with complex operating environments and durability tests.

[0053] In one possible embodiment, the second decorative element 144 further includes a first mating portion 1444, which is disposed around the annular portion 1441. The first decorative element 143 further includes a second mating portion 1432, which is disposed around the body portion 1431, and the first mating portion 1444 engages with the second mating portion 1432.

[0054] A first mating portion 1444 is provided on the outer ring of the annular portion 1441, and a second mating portion 1432 is provided on the outer ring of the main body portion 1431. When the first decorative member 143 and the second decorative member 144 are connected to each other, the first mating portion 1444 and the second mating portion 1432 cooperate with each other to seal, thereby forming a third line of defense. The cooperation between the first mating portion 1444 and the second mating portion 1432 can not only improve the sealing effect within the decorative member assembly 140, but also cover the sealing position between the third groove 153 and the annular portion 1441, preventing the adhesive from being exposed on the product surface. In some embodiments of this application, the main body portion 1431 and the second mating portion 1432 are integrally molded structures; in other embodiments, the main body portion 1431 and the second mating portion 1432 can be separate assembly structures. In some embodiments of this application, the annular portion 1441, the first mating portion 1444, and the extension portion 1442 are integrally molded structures; in other embodiments, they can be separate assembly structures.

[0055] In one possible embodiment, the first channel 142 further includes a third sub-channel 147. A notch 1445 is provided on the side of the first mating portion 1444 facing the second mating portion 1432. Part of the notch 1445 and the second mating portion 1432 enclose each other to form a first through hole 141, while another part of the notch 1445 and the first groove 148 enclose each other to form the third sub-channel 147. One end of the third sub-channel 147 communicates with the first through hole 141, and the other end of the third sub-channel 147 communicates with the first sub-channel 145.

[0056] The first mating part 1444 has a notch 1445 partially machined on the side facing the second mating part 1432. When the first mating part 1444 and the second mating part 1432 approach each other, part of the notch 1445 and the second mating part 1432 enclose each other to form a first through hole 141. Of course, in other embodiments, the notch 1445 can also be provided in the second mating part 1432, or both the first mating part 1444 and the second mating part 1432 can be provided with notches 1445. In some embodiments of this application, the length of the first groove 148 is longer than that of the second groove 149, and the part that extends beyond the second groove 149 can enclose a part of the notch 1445 to form a third sub-channel 147.

[0057] The notch 1445 extends into the interior of the decorative component assembly 140, such that part of the notch 1445 and the first groove 148 enclose each other to form a third sub-channel 147, which connects the first through hole 141 and the first sub-channel 145.

[0058] Combination Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible embodiment, along the thickness direction of the extension 1442, one side of the extension 1442 extends into the fourth groove 151, and the other side of the extension 1442 protrudes from the first decorative member 143.

[0059] Along its thickness direction, the extension 1442 is designed to have sufficient solid thickness. A portion of the extension 1442 extends directly into the fourth groove 151 during assembly. This embedded relationship means that the root of the extension 1442 has sufficient material thickness and structural depth to ensure that the extension 1442, as a cantilever structure, possesses extremely high mechanical strength against bending and torsion. Simultaneously, another portion of the extension 1442 protrudes from the surface of the first decorative element 143 facing the second decorative element 144. This integrated configuration, "partially embedded in the groove and partially protruding from the surface," fundamentally aims to greatly enhance the structural rigidity and stability of the extension 1442 by increasing its thickness. When the extension 1442 has sufficient thickness, it can effectively resist the pressure or lateral impact that may be encountered in the daily use of the electronic device 100, thereby avoiding plastic deformation or even breakage caused by external force, and ensuring the long-term stability of the shape and size of the first sub-channel 145 formed by the extension 1442, which is crucial for maintaining the consistency of acoustic performance.

[0060] Combination Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in one possible embodiment, a rib 163 is provided between the first groove 148 and the third groove 153 and between the first groove 148 and the fourth groove 151, and the rib 163 is provided around the first groove 148.

[0061] A raised rib 163 is provided between the first groove 148 and the third groove 153, and a raised rib 163 is also provided between the first groove 148 and the fourth groove 151. The two sets of raised ribs can be integrally formed. The raised rib 163 can prevent the adhesive between the first groove 148 and the third groove 153 and the first groove 148 and the fourth groove 151 from flowing into the first sub-channel 145, preventing blockage of the first sub-channel 145 and ensuring the smoothness of the sound inlet channel.

[0062] In one possible embodiment, the distance from the opening of the third groove 153 to the bottom wall of the groove is greater than the distance from the opening of the fourth groove 151 to the bottom wall of the groove, and the bottom wall of the third groove 153 and the bottom wall of the fourth groove 151 are connected by a slope 155.

[0063] The distance from the opening of the third groove 153 to the bottom wall is greater than the distance from the opening of the fourth groove 151 to the bottom wall, indicating that the groove depths of the third groove 153 and the fourth groove 151 are different. The bottom walls of the third groove 153 and the fourth groove 151 are not located on the same plane, and they are connected by a slope 155.

[0064] During manufacturing, the bevel 155 facilitates easier demolding of the second decorative part 144 (made of metal or plastic) from the mold after injection molding or stamping, improving production efficiency and part quality. During dispensing, the bevel 155 helps guide the flow and distribution of the adhesive, allowing it to fill the fourth groove 151 more smoothly and preventing air bubbles or insufficient adhesive in corners. This ensures the uniformity and integrity of the dispensing seal. The transitional bevel 155 also enhances the structural strength between the extension 1442 and the annular portion 1441, avoiding the risk of fracture due to stress concentration caused by abrupt changes in cross-section under stress, making the entire structure more robust and durable. In some embodiments of this application, corresponding to the different depths of the third groove 153 and the fourth groove 151, the thicknesses of the annular portion 1441 and the extension 1442 are also different. It is understood that along the thickness direction of the second decorative part 144, the annular portion 1441 protrudes from the extension 1442, thereby better fitting with the third groove 153. In this application, the third groove 153 and the fourth groove 151 are configured as stepped structures, and the annular portion 1441 and the extension portion 1442 are configured as the same stepped structures, in order to reduce the stacking thickness and thus compress the volume of the electronic device.

[0065] Combination Figure 1 , Figure 7 and Figure 12As shown, in one possible embodiment, the electronic device 100 further includes a lens 160 and a first adhesive 170, the first adhesive 170 being stacked on the body portion 1431 and the annular portion 1441, and the lens 160 being connected to the first decorative member 143 and the second decorative member 144 via the first adhesive 170.

[0066] Lens 160 is typically protective glass for the camera area, covering the camera module below. First adhesive 170 can be double-sided tape, and lens 160 is connected to first decorative element 143 and second decorative element 144 via first adhesive 170. First adhesive 170 is used to firmly bond lens 160 to first decorative element 143 and second decorative element 144.

[0067] Combination Figure 1 , Figure 7 , Figure 12 and Figure 13 As shown, in one possible embodiment, the first adhesive member 170 is provided with a first notch 171, and the body portion 1431 is provided with a fifth groove 1433. The first notch 171 and the fifth groove 1433 are disposed opposite each other. The bottom wall of the fifth groove 1433 is provided with a second through hole 1434. The first notch 171, the fifth groove 1433, and the lens 160 together form a second channel 172. There is a gap 157 between the lens 160 and the first mating portion 1444. One end of the second channel 172 communicates with the gap 157. In some embodiments of this application, the area of ​​the first notch 171 is larger than the area of ​​the fifth groove 1433. The first notch 171, the lens 160, the first notch 171, the body portion 1431, and the annular portion 1441 together form a third channel. The third channel communicates with the second channel 172. The second channel 172 communicates with the gap 157 through the third channel, thereby connecting to the external environment.

[0068] The first adhesive part 170 has a first notch 171, which is located on one side of the fifth groove 1433 and is connected to the fifth groove 1433. The second through hole 1434 is a vent hole. The function of the first notch 171 is to connect the tiny gap 157 between the edge of the lens 160 and the side of the second decorative part 144 with the second channel 172, which is a venting channel.

[0069] In this embodiment, the first notch 171 is a pre-defined hole or groove that penetrates the first adhesive 170. By providing the second channel 172, the inside of the electronic device 100 can be connected to the outside, reducing the risk of internal pressure buildup, such as earpiece sound distortion, screen pressure, or battery swelling.

[0070] Combination Figure 1 , Figure 7 and Figure 12As shown, in one possible embodiment, the first adhesive 170 is provided with a second notch 173, which is disposed opposite to the extension 1442.

[0071] The first adhesive member 170 has a second notch 173, which is an opening or groove punched or reserved according to the shape and position of the protruding part of the extension 1442. When the lens 160 is pasted through the first adhesive member 170, the second notch 173 provides physical space to avoid the extension 1442 protruding from the first decorative member 143, preventing the first adhesive member 170 from directly pressing on the extension 1442, which would cause the lens 160 to be unevenly pasted or generate stress. This ensures that the lens 160 can be installed flat, improves the bonding effect of the lens 160, and avoids damage to the extension 1442.

[0072] In one possible embodiment, the lens 160 is provided with a third through hole 161, which communicates with the second channel 172.

[0073] External air can enter the interior of the electronic device 100 through the third through-hole 161 on the lens 160, and then enter the interior of the electronic device 100 through the channel in the decorative component assembly 140 to balance the air pressure. However, in actual use, the third through-hole 161 on the surface of the lens 160 is easily partially or completely blocked by sebum, dust or other contaminants from the palm, causing the air pressure balancing function to fail, which may lead to the accumulation of internal pressure difference, causing risks such as earpiece sound distortion, screen pressure or battery swelling. In this embodiment, even if the third through-hole 161 on the front of the lens 160 is completely blocked, external air can still circulate through the second channel 172. In some embodiments of this application, after the body portion 1431 and the annular portion 1441 are engaged, the surface of the body portion 1431 is flush with the surface of the annular portion 1441, so that the first adhesive 170 is flatly attached to the body portion 1431 and the annular portion 1441, thereby avoiding wrinkles or protrusions that affect the overall thickness. In some embodiments of this application, a buffer 180 is provided between the extension 1442 and the lens 160. The buffer 180 can be a flexible deformable structure such as colloid or foam.

[0074] The second channel 172 creates a redundant, blockage-resistant pressure balancing pathway.

[0075] Combination Figure 1 , Figure 7 , Figure 12 and Figure 13 As shown, in one possible embodiment, a first waterproof and breathable element 162 is provided in the third through hole 161; and / or, a second waterproof and breathable element 158 ​​is provided in the second through hole 1434.

[0076] A first waterproof and breathable component 162 is installed within the third through-hole 161. This first waterproof and breathable component 162 is typically a special thin film (such as expanded polytetrafluoroethylene film) that allows air molecules to pass through but blocks liquid water and dust particles. The third through-hole 161 ensures timely balance of internal and external air pressure, preventing problems such as earpiece noise, screen pressure, or battery swelling caused by pressure differences. Furthermore, the built-in third through-hole 161 ensures waterproof and dustproof performance. Placing the third through-hole 161 on the lens 160 and integrating it with the channel within the decorative component assembly 140 simplifies the external opening layout.

[0077] In addition to the first waterproof and breathable element 162 at the third through-hole 161, a second waterproof and breathable barrier is set deeper in the gas path, namely, a second waterproof and breathable element 158 ​​is installed inside the second through-hole 1434. This dual protection design constitutes a redundant safety system. Even if the first waterproof and breathable element 162 at the lens 160 experiences a decrease in effectiveness due to accidental contamination or partial blockage, the second waterproof and breathable element 158 ​​can still provide effective waterproof and dustproof protection, greatly improving the protective reliability of the air pressure balance channel throughout the entire product lifecycle.

[0078] Combination Figure 1 and Figure 7 As shown, in one possible embodiment, the electronic device 100 further includes a buffer 180 located between the lens 160 and the extension 1442.

[0079] The buffer 180 is typically made of an elastic material such as foam or rubber, and is positioned between the lower surface of the lens 160 and the extension 1442. When the lens 160 is in place, the buffer 180 is slightly compressed, providing cushioning and shock absorption. In the event of a drop or impact to the electronic device 100, the buffer prevents the lens 160 from making hard contact with the rigid extension 1442 below, thus avoiding breakage of the lens 160 or the decorative ring and improving the impact resistance reliability of the electronic device 100.

[0080] The buffer 180 provides an additional support point for the lens 160 in the corresponding area, preventing the lens 160 from deforming or vibrating under pressure due to the center being suspended.

[0081] Combination Figure 1 , Figure 7 and Figure 14 As shown, in one possible embodiment, the electronic device 100 further includes a bracket 121 and a seal 190, at least a portion of the bracket 121 being located within the housing assembly 110, and a microphone assembly 130 being disposed on the side of the bracket 121 facing the first decorative element 143. The seal 190 is located between the first decorative element 143 and the microphone assembly 130.

[0082] The seal 190 is located between the first trim 143 and the microphone assembly 130. When the first trim 143 and the microphone assembly 130 are assembled and pressed together, the seal 190 deforms and tightly fills the assembly gap between them, thereby achieving a reliable acoustic seal and a physical seal.

[0083] Combination Figure 1 , Figure 7 and Figure 14 As shown, in one possible embodiment, the seal 190 includes a soft rubber part 191, a support part 192, a third waterproof and breathable part 193, and a second adhesive part 194. The soft rubber part 191 is provided with a through hole, the support part 192 is located on the side of the soft rubber part 191 opposite to the first decorative part 143, the third waterproof and breathable part 193 is located on the side of the support part 192 opposite to the soft rubber part 191, and the second adhesive part 194 is used to bond the third waterproof and breathable part 193 to the microphone assembly 130.

[0084] The core component of the seal 190 is the soft rubber part 191. This is because the soft rubber part 191 has good elasticity, low compression set, and weather resistance, enabling it to form a long-term stable seal. The soft rubber part 191 is provided with a through hole. The elasticity of the soft rubber part 191 ensures that when the first decorative part 143 and the microphone assembly 130 are assembled and pressed together, the soft rubber part 191 will deform and tightly fill the assembly gap between them, thereby achieving a reliable acoustic and physical seal.

[0085] Acoustically, the sealing effect of the soft rubber part 191 ensures that sound is transmitted undamagedly from the first channel 142 to the microphone assembly 130, and also prevents moisture and dust from entering the device motherboard area from the microphone assembly 130 mounting interface.

[0086] A support member 192 is stacked on the side of the soft rubber part 191 facing away from the first decorative part 143. The support member 192 is typically made of a rigid material such as PET (Polyethylene Terephthalate). The function of the support member 192 is to provide support for the soft rubber part 191, prevent the soft rubber part 191 from being excessively deformed or twisted under pressure, ensure a uniform distribution of sealing pressure, and protect the underlying third waterproof and breathable part 193. In some embodiments of this application, the soft rubber part 191 can be a plastic part, a rubber part, or a silicone part. A third waterproof and breathable part 193 is provided on the side of the support member 192 facing away from the soft rubber part 191. It is positioned corresponding to the through-hole of the soft rubber part 191. The third waterproof and breathable part 193 allows sound waves and air to pass through but blocks moisture. The entire composite seal 190 is firmly bonded to the housing of the microphone assembly 130 using a second adhesive 194 (such as double-sided tape). Therefore, the seal 190 in this embodiment is an integrated component that combines excellent sealing performance, mechanical stability, high acoustic permeability, and high-level protection.

[0087] The support member 192 and the second adhesive member 194 also need to be provided with openings.

[0088] The housing assembly 110 includes a frame 111 and a battery cover 112. The battery cover 112 is located on the back of the frame 111. A first channel 142 is designed on the decorative component assembly 140 of the battery cover 112, which does not affect the appearance or the overall airtightness test. The first through hole 141 is designed between two decorative rings, using the two-layer structure of the decorative rings to create the first channel 142, minimizing the impact on the appearance. The first channel 142 is sealed with adhesive. To test the overall airtightness, a soft rubber component 191 is used to seal between the decorative ring and the microphone assembly 130. Only one hole is made on the lens 160 as a third through hole 161. To prevent clogging, the gap 157 between the lens 160 and the decorative ring is connected to the second channel 172, thus solving the clogging problem.

[0089] The electronic device 100 also includes a circuit board main board 122, which is fixed on a bracket 121. The microphone assembly 130 includes a microphone 131 and an adapter board 132, which is connected to the circuit board main board 122 and the microphone 131 is connected to the adapter board 132.

[0090] Microphone 131 is soldered onto adapter flexible board 132. Sound enters through the first through hole 141 and then enters the microphone 131 through the first channel 142. The first channel 142 is formed by sealing the upper and lower decorative rings with adhesive. Adhesive 159 is placed between the upper and lower decorative rings. Lens 160 is bonded to the first decorative part 143 with double-sided adhesive. A foam is attached to the second decorative part 144 to support the lens 160. The first decorative part 143 is reinforced and sealed by the microphone assembly 130.

[0091] The inlet of the microphone assembly 130 is some distance from the first through hole 141 of the decorative component assembly 140. A channel needs to be designed to connect these two locations. The second decorative component 144 is partially extended inward to form an extension 1442, and the first decorative component 143 is correspondingly made into a U-shape. Due to the overall thickness limitation, in this embodiment, the first channel 142 is divided into two, with the first sub-channel 145 distributed between the upper and lower decorative rings. The upper and lower decorative rings are sealed with adhesive. The lens 160 and the second decorative component 144 are both assembled into the lower decorative ring. Due to the thickness bottleneck, the bottom wall of the third groove 153 and the bottom wall of the fourth groove 151 are not on the same plane. The bottom wall of the third groove 153 and the bottom wall of the fourth groove 151 are smoothly transitioned by the inclined surface 155, solving the adhesive sealing problem.

[0092] Electronic device 100 typically requires IP68 waterproof capability. The overall waterproof test usually requires measuring airtightness through the first through-hole 141. Since the first through-hole 141 is located on the side of the decorative ring and between the upper and lower decorative rings, and is not on the same plane, the test fixture cannot seal it. Therefore, a soft rubber component 191 is needed to seal the space between the lower decorative ring and the adapter flexible board 132; conventional foam cannot be used. For waterproofing, sound can enter the microphone 131. A hole is made in the center of the soft rubber component 191, which is sealed with a waterproof and breathable membrane. The sealing component 190 is composed of the soft rubber component 191, PET, the waterproof and breathable membrane, and double-sided adhesive, stacked together.

[0093] The first channel 142 is set on the decorative component 140. Due to the thickness space bottleneck of the decorative component 140, the double-sided tape for attaching the lens 160 is partially notched. The second decorative component 144 uses the notch in the double-sided tape to form a partial protrusion. In order to prevent the lens 160 from hitting the second decorative component 144, shock-absorbing foam is attached to the upper end of the second decorative component 144.

[0094] To save space in the main and auxiliary board layout and to solve the problem of the third through hole 161 being blocked, ventilation is utilized through the gap 157 between the lens 160 and the second decorative part 144. Therefore, an opening is designed in the double-sided adhesive of the lens 160 to connect the channel of the third through hole 161 with the aforementioned gap 157. To prevent the gap 157 from affecting the first channel 142, an adhesive dispensing method is used for isolation.

[0095] Given the bottleneck of overall thickness, a portion of the first channel 142 is designed between the upper and lower decorative rings. The channel is sealed using an adhesive dotting method, which not only effectively seals the channel but also blocks interference caused by the air gap 157 between the lens 160 and the decorative ring.

[0096] For example, electronic device 100 can be an electronic product such as a mobile phone, e-book, or tablet computer.
