Description
Technical Field
[0001] This application belongs to the field of communication technology, and specifically relates to an electronic device. Background Technology
[0002] With technological advancements, electronic devices (such as mobile phones and tablets) have developed significantly. As powerful tools, electronic devices have greatly facilitated users' lives and work. Electronic devices are equipped with acoustic devices such as speakers and microphones to enable functions such as audio playback and recording.
[0003] In related technologies, electronic devices include a housing and acoustic devices. The acoustic devices are located inside the electronic devices, and the electronic devices have through holes communicating with their internal cavity. The acoustic devices are positioned opposite to the through holes. In this case, the acoustic devices guide sound to the outside of the electronic devices through the through holes, or external sound is transmitted to the acoustic devices inside the electronic devices through the through holes.
[0004] However, in related technologies, the through-holes are typically located on the back cover of the electronic device's casing. In this case, the user's palm can easily block the through-hole during use, reducing its actual sound-conducting area and consequently affecting the electronic device's acoustic performance. Furthermore, since the through-hole is positioned opposite the acoustic component, external dust can easily enter through it and fall directly onto the acoustic component, potentially clogging the sound holes and resulting in poor sound production or reception. Therefore, the acoustic performance of electronic devices in these technologies is relatively poor. Summary of the Invention
[0005] The purpose of this application is to provide an electronic device that can solve the technical problem that the acoustic components of the electronic device are easily blocked, resulting in poor acoustic performance.
[0006] To solve the above-mentioned technical problems, this application is implemented as follows: This application discloses an electronic device, comprising: Acoustic devices; The housing has a first through hole; A decorative cover is disposed on the housing and covers the first through hole; a sound-guiding gap is formed between the edge of the decorative cover facing the housing and the housing. A first bracket is disposed on the side of the decorative cover facing the first through hole. The first bracket is used to form a sound guiding channel. One end of the sound guiding channel is connected to the sound guiding gap, and the other end of the sound guiding channel is connected to the acoustic device.
[0007] In this embodiment, a sound-guiding gap is formed between the edge of the decorative cover and the housing. A first bracket is disposed on the side of the decorative cover facing the first through hole. One end of the sound-guiding channel is connected to the sound-guiding gap, and the other end of the sound-guiding channel is connected to the acoustic device. In this design, the sound-guiding gap is located below the decorative cover, so the user's palm is less likely to block the sound-guiding gap, thus less likely to affect the sound-guiding area of the sound-guiding gap, and consequently less likely to affect the acoustic performance of the electronic device. In addition, the first bracket is used to form the sound-guiding channel, which lengthens the sound-guiding path of the electronic device, thus avoiding the risk of external dust and moisture falling directly onto the acoustic device, thereby avoiding the risk of clogging the acoustic device. Therefore, the electronic device disclosed in this application can avoid both the risk of the sound-guiding position being blocked and the risk of the acoustic device being blocked, thus improving the acoustic performance of the electronic device.

Detailed Implementation The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0011] The camera module and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.
[0012] Please refer to Figures 1 to 18 This application discloses an electronic device, which includes a housing 100, a decorative cover 200, an acoustic device 300, and a first bracket 400.
[0013] The housing 100 provides a mounting base for other components of the electronic device. The housing 100 has an inner cavity and a first through-hole 103 communicating with the inner cavity. This inner cavity can be used to mount other components of the electronic device, such as the acoustic device 300, circuit boards, etc. The first through-hole 103 exposes components within the inner cavity. For example, the first through-hole 103 can be aligned with a camera module of the electronic device located within the inner cavity, thereby exposing the camera module and facilitating its light reception. Alternatively, it can also expose components such as the acoustic device 300, a fingerprint module, etc.
[0014] Furthermore, different housing structures 100 result in different components. For example, housing 100 may include a front cover, a rear cover, and a middle frame disposed between them. The aforementioned inner cavity may be formed jointly by the front cover, the rear cover, and the middle frame disposed between them. As another example, housing 100 may include a front cover and a rear cover, and the aforementioned middle frame may be formed on either the front cover or the rear cover; that is, the middle frame may be integrally formed with either the front cover or the rear cover. Here, the rear cover can also be understood as a battery cover. Of course, housing 100 may also have other structures, which are not limited herein.
[0015] In this application, the housing 100 may have an inner surface 101 and an outer surface 102 disposed opposite to each other. The outer surface 102 is the external appearance surface of the electronic device, and the inner surface 101 is used to enclose the aforementioned internal cavity. The aforementioned first through hole 103 extends from the inner surface 101 to the outer surface 102. Specifically, the aforementioned inner surface 101 and outer surface 102 may be provided on the rear cover, therefore the first through hole 103 is formed on the rear cover of the housing 100.
[0016] The acoustic device 300 is disposed within the cavity of the housing 100 and is used to realize the acoustic performance of the electronic device. For example, the acoustic device 300 can be a sound-generating device, which can realize the sound playback function of the electronic device. Alternatively, the acoustic device 300 can be a sound-collecting device, which can realize the sound acquisition function of the electronic device.
[0017] A decorative cover 200 is disposed on the housing 100 and covers the first through hole 103. The decorative cover 200 is used to shield functional devices opposite to the first through hole 103. For example, the decorative cover 200 is used to shield functional modules such as camera modules, fill light modules, and fingerprint modules. A sound-guiding gap 620 is formed between the edge of the decorative cover 200 facing the housing 100 and the housing 100. An assembly gap is formed between the edge of the decorative cover 200 facing the housing 100 and the housing 100, and at least a portion of the assembly gap forms the aforementioned sound-guiding gap 620. This sound-guiding gap 620 is used for sound guiding in electronic devices. In this case, the decorative cover 200 can be disposed on the outer surface 102 of the housing 100. For example, the decorative cover 200 can be bonded to the outer surface 102 of the housing 100 using adhesive structures such as double-sided tape or glue. The aforementioned sound-guiding gap 620 is formed between the edge of the decorative cover 200 facing the outer surface 102 of the housing 100 and the outer surface 102 of the housing 100. This can be understood as meaning that no adhesive structure is required at the sound guide gap 620, or the adhesive structure at the sound guide gap 620 can be removed to ensure that the sound guide gap 620 is not blocked by the adhesive structure.
[0018] The first bracket 400 is located on the side of the decorative cover 200 facing the first through hole 103. The first bracket 400 is used to form a sound guiding channel 610. One end of the sound guiding channel 610 is connected to the sound guiding gap 620, and the other end of the sound guiding channel 610 is connected to the acoustic device 300.
[0019] In specific operation, when the acoustic device 300 is a sound pickup device, when the user emits a sound, the sound enters the electronic device through the sound guide slit 620, and then is transmitted to the acoustic device 300 through the sound guide channel 610. In this embodiment, the acoustic device 300 can be a microphone. When the acoustic device 300 is a sound emission device, when the acoustic device 300 emits sound, the sound is transmitted to the sound guide slit 620 through the sound guide channel 610, and then transmitted outside the electronic device through the sound guide slit 620. In this embodiment, the acoustic device 300 can be a receiver or a speaker.
[0020] In the embodiments disclosed in this application, the sound-conducting slit 620 is located below the decorative cover 200, so the user's palm is unlikely to block the sound-conducting slit 620, thus minimizing the impact on the sound-conducting area of the slit 620. Furthermore, the first bracket 400 forms a sound-conducting channel 610, which lengthens the sound-conducting path of the electronic device, thereby avoiding the risk of the sound-conducting slit 620 directly facing the acoustic device 300, and thus preventing external dust and moisture from falling directly onto the acoustic device 300, thereby avoiding the risk of the acoustic device 300 being blocked. At the same time, compared to the through-hole sound-conducting method in related technologies, the sound-conducting slit 620 is narrower, effectively mitigating the entry of environmental moisture and dust into the sound-conducting channel 610, further preventing the risk of the acoustic device 300 being blocked. Therefore, the electronic device disclosed in this application can avoid both the risk of the sound-conducting position being blocked and the risk of the acoustic device 300 being blocked, thus effectively improving the acoustic performance of the electronic device.
[0021] Furthermore, the electronic device in this application transmits sound through the assembly gap between the decorative cover 200 and the housing 100, thereby eliminating the need for through holes for sound conduction on the housing 100, reducing the number of openings in the housing 100, thereby improving the integrity and appearance consistency of the housing 100, resulting in a better appearance and improved user experience.
[0022] If the sound guiding channel 610 in the above embodiments is separately provided on the decorative cover 200 or the housing 100, the thickness of the decorative cover 200 or the wall thickness of the housing 100 needs to be increased to meet the requirements for the sound guiding channel 610. The greater the thickness of the decorative cover 200, the higher its protrusion from the housing 100, making the electronic device appear bulky and obtrusive, thus resulting in poor aesthetic performance. In addition, a larger wall thickness of the housing 100 also contributes to a poorer appearance of the electronic device.
[0023] In the embodiments disclosed in this application, the first bracket 400 is disposed on the side of the decorative cover 200 facing the first through hole 103, and the first bracket 400 is used to form a sound guiding channel 610. This can be understood as the first bracket 400 itself forming the sound guiding channel 610, or the first bracket 400 forming the sound guiding channel 610 together with at least one of the decorative cover 200 or the housing 100. In this case, the sound guiding channel 610 is formed by the first bracket 400 connected to the decorative cover 200. Since the first bracket 400 is the main component forming the sound guiding channel 610, the opening of the sound guiding channel 610 does not depend on the thickness of the decorative cover 200 or the wall thickness of the housing 100, thereby reducing the thickness of the decorative cover 200 and the wall thickness of the housing 100. Therefore, the electronic device in this application can design the decorative cover 200 to be smaller and thinner, while also further achieving the thinness and lightness of the housing 100, thus contributing to a better appearance of the electronic device.
[0024] Furthermore, the sound guide channel 610 mainly relies on the first bracket 400, so it is not easy to affect the seal between the decorative cover 200 and the housing 100. Therefore, this solution can improve the acoustic performance of the electronic device and ensure the sealing performance between the decorative cover 200 and the housing 100.
[0025] In addition, the first bracket 400 is connected to the decorative cover 200, so the first bracket 400 can be detached from the housing 100, thereby avoiding the occupation of space in the housing 100, which helps to reduce the occupation of the inner cavity of the housing 100, and thus helps to further optimize the spatial layout of the electronic device.
[0026] In one embodiment, the electronic device may further include a camera module, with the lens of the camera module facing the first through-hole 103. In this case, the decorative cover 200 is used to cover the camera module. Of course, the decorative cover 200 disclosed in this application is not limited to covering the camera module; it can also be used to cover other functional devices, and this is not a limitation herein.
[0027] In one optional embodiment, the decorative cover 200 has a notch 201 on its edge facing the housing 100. The notch 201 can be closed with the housing 100 to form a sound-guiding gap 620. In this solution, the notch 201 on the edge of the decorative cover 200 increases the width of the sound-guiding gap 620, thereby increasing the sound-guiding area and further avoiding the risk of the sound-guiding gap 620 being blocked.
[0028] In another alternative design, the sound guide slit 620 can be elongated and narrow. By reducing the width of the sound guide slit 620, it becomes more concealed. This width is the distance between the decorative cover 200 and the housing 100 forming the sound guide slit 620. In this case, the user is less likely to see the sound guide slit 620, thus improving the appearance and quality of the electronic device. The sound guide slit 620 can extend along the edge of the decorative cover 200. In this case, by increasing the length of the sound guide slit 620, the area of the assembly gap can be increased, thereby meeting the sound guiding requirements of the acoustic device 300.
[0029] The size of the sound guide gap 620 in the above scheme can be 0.3X5mm. Of course, the size of the sound guide gap 620 is not limited to the above size and can also be other sizes. This article does not impose any restrictions.
[0030] In one embodiment, the first bracket 400 may have a groove 4021 on the side facing the decorative cover 200. The groove 4021 can be used to form a sound guiding channel 610 with the decorative cover 200. At this time, the decorative cover 200 covers the opening of the groove 4021, so that the groove 4021 and the decorative cover 200 form the sound guiding channel 610. In this solution, the design of the groove 4021 simplifies the molding method of the sound guiding channel 610, thereby reducing the molding difficulty of the sound guiding channel 610. In addition, the groove 4021 and the decorative cover 200 forming the sound guiding channel 610 together, compared with the method of the first bracket 400 having a separate sound guiding channel 610, the groove 4021 has an open structure, so it is easier to demold the first bracket 400 and reduce the manufacturing cost. Meanwhile, the groove 4021 and the decorative cover 200 together form a sound guiding channel 610, which can increase the cross-sectional area of the sound guiding channel 610, thereby improving the reliability of sound guiding, and also make the thickness of the first bracket 400 smaller, thereby further realizing the development of thinner and lighter electronic devices.
[0031] In the above embodiment, the electronic device may further include an adhesive portion 500, through which the first bracket 400 and the decorative cover 200 can be bonded. The adhesive portion 500 may be disposed on the edge of the first bracket 400. For example, the adhesive portion 500 may be bonded along the edge of the first bracket 400.
[0032] In another alternative embodiment, the adhesive portion 500 may be located between the first bracket 400 and the decorative cover 200. The adhesive portion 500 may have a mating notch 501 extending along a first direction, which may be opposite to and connected to the opening of the groove 4021. The groove 4021, the mating notch 501, and the decorative cover 200 together form a sound guiding channel 610. The first direction may be the direction from the first bracket 400 to the decorative cover 200. This first direction can also be understood as the thickness direction of the electronic device. The adhesive portion 500 may be double-sided adhesive.
[0033] In this design, the adhesive portion 500 is located between the first bracket 400 and the decorative cover 200, thereby increasing the adhesive area between the first bracket 400 and the decorative cover 200, effectively improving the assembly reliability of the first bracket 400 and the decorative cover 200. Furthermore, the adhesive portion 500 has a mating notch 501 opposite to the groove 4021. The mating notch 501 can form a sound guiding channel 610, thus increasing the cross-sectional area of the sound guiding channel 610, further improving sound guiding reliability.
[0034] Furthermore, along the first direction, the projected area of the adhesive portion 500 is larger than the projected area of the first bracket 400. In this design, the edge of the adhesive portion 500 extends beyond the edge of the first bracket 400, thus preventing the adhesive portion 500 from retracting and causing an undercut, and avoiding the risk of poor sealing between the first bracket 400 and the decorative cover 200.
[0035] Optionally, the edge of the adhesive portion 500 may extend beyond the edge of the first bracket 400 by a dimension greater than or equal to 0.3 mm.
[0036] In the above solution, the port of the sound guiding channel 610 near the sound guiding gap 620 is easily blocked. Therefore, in an alternative solution, the sound guiding channel 610 includes a first channel 611 and a second channel 612 connected in sequence. The end of the first channel 611 opposite to the second channel 612 can be connected to the acoustic device 300. The end of the second channel 612 opposite to the first channel 611 is connected to the sound guiding gap 620.
[0037] The cross-section of the second channel 612 along the direction perpendicular to its axis can be the first cross-section. As the second channel 612 extends away from the first channel 611, the area of the first cross-section gradually increases, such as... Figure 3 As shown. The direction perpendicular to the axis of the second channel 612 can be the first direction mentioned above.
[0038] In this scheme, the second channel 612 is a gradually expanding structure away from the first channel 611. At this time, the closer to the sound guide slit 620, the larger the area of the second cross section of the second channel 612. Therefore, the cross section area of the second channel 612 facing the sound guide slit 620 is larger, thus further avoiding the risk of the port of the sound guide channel 610 near the sound guide slit 620 being blocked.
[0039] In one embodiment, the cross-sectional area of the first channel 611 along the direction perpendicular to the axis of the first channel 611 can be constant in the extension direction of the first channel 611.
[0040] Alternatively, the first channel 611 can also be a gradually expanding structure toward the second channel 612.
[0041] Alternatively, the first channel 611 may include two channel segments with different cross-sectional areas. The first segment is connected to the second channel 612 via the second segment, and the cross-sectional area of the first segment is smaller than that of the second segment. In a specific embodiment, the groove 4021 may include a first groove segment 4021a and a second groove segment 4021b. One end of the first groove segment 4021a may be connected to the acoustic device 300, and the end of the first groove segment 4021a facing away from the acoustic device 300 may be connected to the second groove segment 4021b. The end of the second groove segment 4021b facing away from the first groove segment 4021a extends to the edge of the first support 400 and is connected to the sound guide gap 620. At this time, the first groove segment 4021a and the decorative cover 200 form the first channel 611, and the second groove segment 4021b and the decorative cover 200 form the second channel 612. The depth of the second groove segment 4021b gradually increases in the direction away from the first groove segment 4021a, thereby making the cross-sectional area of the second channel 612 gradually increase.
[0042] In the above scheme, the depth of the first groove segment 4021a can be constant, while the width of the first groove segment 4021a can be set differently. For example, the width of the groove segment corresponding to the first segment is smaller than the width of the groove segment corresponding to the second segment.
[0043] The cross-sectional areas at the connection between the first channel 611 and the second channel 612 can be equal.
[0044] In one alternative embodiment, the decorative cover 200 may have a first sealing surface 202 on the side facing the housing 100, which seals against the housing 100. However, in this application, the decorative cover 200 is connected to a first bracket 400, which disrupts the continuity of the first sealing surface 202. Therefore, this application requires a second sealing surface 4031 on the side of the first bracket 400 facing away from the decorative cover 200, which seals against the housing 100. In this case, the first sealing surface 202 and the second sealing surface 4031 can achieve a circumferential seal between the decorative cover 200 and the housing 100. However, the first bracket 400 protrudes from the surface of the decorative cover 200, which can easily lead to a height difference between the first sealing surface 202 and the second sealing surface 4031, thus increasing the difficulty of sealing.
[0045] Based on this, in another optional embodiment, the decorative cover 200 may have a receiving groove 203 on the side facing the housing 100, and the edge of the decorative cover 200 facing the housing 100 may have the aforementioned first sealing surface 202. The first sealing surface 202 may be arranged around the receiving groove 203. Optionally, in some embodiments of this application, the first sealing surface 202 is provided on the edge of the decorative cover 200 facing the housing 100, excluding the clearance notch 201. The first sealing surface 202 and the second sealing surface 4031 may extend along the edge of the decorative cover 200. The first sealing surface 202 and the second sealing surface 4031 are sealed and engaged with the housing 100 by a sealing structure 630. At least a portion of the first bracket 400 is located within the receiving groove 203, so that the second sealing surface 4031 and the first sealing surface 202 are flush.
[0046] In this design, at least a portion of the first bracket 400 is located within the receiving groove 203. This reduces the height of the first bracket 400 protruding from the decorative cover 200, allowing the first sealing surface 202 and the second sealing surface 4031 to be flush along the aforementioned first direction. This enables a smooth transition between the corresponding portions of the sealing structure 630 on the first sealing surface 202 and the corresponding portions of the sealing structure 630 on the second sealing surface 4031, effectively reducing the sealing difficulty between the decorative cover 200 and the housing 100. Furthermore, placing the first bracket 400 within the receiving groove 203 reduces the amount of the first bracket 400 protruding into the inner cavity of the housing 100, further avoiding encroachment on the inner cavity of the housing 100 and facilitating a further reduction in the thickness of the electronic device.
[0047] In the above embodiment, the first bracket 400 is disposed in the receiving groove 203, so the second sealing surface 4031 is located in the area within the groove opening of the receiving groove 203, while the first sealing surface 202 is disposed around the groove opening of the receiving groove 203, resulting in the first sealing surface 202 and the second sealing surface 4031 being relatively misaligned in the radial direction along the receiving groove 203. Therefore, the sealing reliability at the junction of the first sealing surface 202 and the second sealing surface 4031 is poor.
[0048] Based on this, in another optional embodiment, the inner sidewall of the receiving groove 203 may be provided with a recess 204 communicating with the receiving groove 203, and the recess 204 may be disposed opposite to the sound guiding gap 620. This can be understood as the recess 204 being located at the position of the sound guiding gap 620, facilitating communication between the sound guiding channel 610 and the sound guiding gap 620.
[0049] The first bracket 400 may include a first portion 410 and a second portion 420 connected to each other. The first portion 410 may be located within the receiving groove 203, and the second portion 420 may be located within the relief recess 204. A second sealing surface 4031 may be provided on the side of the second portion 420 facing away from the decorative cover 200. In this design, the second portion 420 of the first bracket 400 is located within the relief recess 204 in the receiving groove 203, thereby increasing the area where the first sealing surface 202 and the second sealing surface 4031 intersect. This improves the sealing reliability at the intersection of the first sealing surface 202 and the second sealing surface 4031, further enhancing the overall sealing reliability.
[0050] In the embodiments disclosed in this application, by providing a receiving groove 203 on the decorative cover 200, the first sealing surface 202 and the second sealing surface 4031 can be aligned front to back along the first direction. By providing a clearance recess 204 on the side wall of the receiving groove 203, the first sealing surface 202 and the second sealing surface 4031 can be aligned along the direction perpendicular to the first direction. Since the widths of the first sealing surface 202 and the second sealing surface 4031 can be different, it can be understood here that at least one side of the first sealing surface 202 and the second sealing surface 4031 is aligned. At this time, the sealing part on the first sealing surface 202 and the sealing part on the second sealing surface 4031 can form an integral annular sealing structure 630.
[0051] For example, adhesive can be applied to the first sealing surface 202 and the second sealing surface 4031, and after the sealant cures, a unified annular sealing structure 630 is formed. Of course, the sealing structure 630 here is not limited to sealant; it can also be double-sided adhesive.
[0052] In another alternative embodiment, the second part 420 has a first notch 421 and a second notch 422 on the side opposite to the first part 410. The first notch 421 and the second notch 422 can be located at opposite ends of the second part 420. This can be understood as the arrangement direction of the first notch 421 and the second notch 422 being perpendicular to the arrangement direction of the first part 410 and the second part 420. The first notch 421 and the recess 204 together form a first adhesive groove 640, where the first notch 421 and its opposite sidewall of the recess 204 form the first adhesive groove 640. The second notch 422 and the recess 4021 together form a second adhesive groove 650, where the second notch 422 and its opposite sidewall of the recess 204 form the second adhesive groove 650. A portion of the sealing structure 630 can be located within the first adhesive groove 640 and the second adhesive groove 650. This can be understood as the portion of the sealing structure 630 located at the junction of the first sealing surface 202 and the second sealing surface 4031 being situated within the first adhesive groove 640 and the second adhesive groove 650. Figure 11 As shown. For example, the adhesive applied to the first sealing surface 202 and the second sealing surface 4031 can flow into the first adhesive groove 640 and the second adhesive groove 650.
[0053] In this design, part of the sealing structure 630 can enter the first adhesive groove 640 and the second adhesive groove 650, thus making the first bracket 400, the adhesive part 500, the decorative cover 200 and the housing 100 all sealed together as one unit, which helps to further improve the overall sealing performance of the electronic device.
[0054] In the above scheme, the area of the first glue groove 640 and the second glue groove 650 along the first direction can be 1.6 x 2 mm or more, and the groove depth can be less than 2 mm. Of course, the first glue groove 640 and the second glue groove 650 can also be other sizes, which are not limited in this article.
[0055] To improve the flowability of the adhesive within the dispensing tank, the edges and corners of the first dispensing tank 640 and the second dispensing tank 650 are rounded, thereby enhancing the flowability of the adhesive within the tank. Optionally, the radius of the rounded corner can be greater than or equal to 0.3 mm. Of course, the radius of the rounded corner can also be other values, which are not limited herein.
[0056] In an optional embodiment, the second part 420 is provided with a third notch 423 on the side opposite to the first part 410. The third notch 423 can be located between the first notch 421 and the second notch 422. The sound guide gap 620 can be connected to the sound guide channel 610 through the third notch 423.
[0057] In this design, the third notch 423 can increase the sound guiding area at the connection between the sound guiding channel 610 and the sound guiding gap 620, thereby avoiding the risk of the end of the sound guiding channel 610 facing the sound guiding gap 620 being blocked, and further improving the reliability of the electronic device's sound guiding.
[0058] In another embodiment, the surfaces of the first portion 410 and the second portion 420 facing the decorative cover 200 are flush. Along the first direction, the thickness of the first portion 410 can be less than the thickness of the second portion 420. In this embodiment, the second portion 420 has a second sealing surface 4031, so the thickness of the second portion 420 can be set to be larger, allowing the second sealing surface 4031 to be flush with the first sealing surface 202. The smaller thickness of the first portion 410 facilitates the thinning of the first bracket 400, thereby contributing to the thinning and lightening of electronic devices.
[0059] In another optional embodiment, the outer edge of the first sealing surface 202 may be provided with a first adhesive-blocking protrusion 205, which extends along the extending direction of the first sealing surface 202. The second sealing surface 4031 may be provided with a second adhesive-blocking protrusion 404, which is located on the edge of the second sealing surface 4031 facing the sound guide gap 620. The first adhesive-blocking protrusion 205 and the second adhesive-blocking protrusion 404 are arranged side by side with the sealing structure 630. In this case, the first adhesive-blocking protrusion 205 is used to block the portion of the sealing structure 630 on the first sealing surface 202, and the second adhesive-blocking protrusion 404 is used to block the portion of the sealing structure 630 on the second sealing surface 4031, thereby avoiding the risk of adhesive overflow during the dispensing process.
[0060] The aforementioned clearance notch 201 can penetrate the first adhesive-blocking protrusion 205. Optionally, in some embodiments of this application, the clearance notch 201 penetrates both the first adhesive-blocking protrusion 205 and the annular protrusion 220.
[0061] Optionally, the decorative cover 200 may include a cover body 210, an annular protrusion 220, and the aforementioned first sealing protrusion 205. The annular protrusion 220 is provided on the side of the cover body 210 facing the housing 100, and a first sealing surface 202 is provided on the side of the annular protrusion 220 away from the cover body 210. The annular protrusion 220 and the cover body 210 enclose to form a receiving groove 203, and the aforementioned clearance recess 204 is formed on the inner circumferential surface of the annular protrusion 220. The first sealing protrusion 205 is provided on the annular protrusion 220. The sound guiding gap 620 in this application may be formed by the first sealing protrusion 205 and the housing 100, or the clearance recess 204 may be formed by the first sealing protrusion 205, the annular protrusion 220, and the housing 100. Alternatively, a portion of the clearance recess 204 may also be formed on the annular protrusion 220. This article does not restrict the specific location of the recess 204.
[0062] In another alternative embodiment, the first bracket 400 may have a second through hole 401 communicating with the groove 4021. The second through hole 401 may be connected to the end of the groove 4021 opposite to the sound guiding gap 620. In this case, the sound guiding channel 610 is connected to the acoustic device 300 through the second through hole 401.
[0063] In this design, the second through-hole 401 can serve as an impedance adjustment section. By adjusting the diameter and length of the second through-hole 401, the output impedance of the acoustic device 300 and the transmission impedance of the sound guide channel 610 can be flexibly matched, reducing sound wave reflection and standing wave formation at the interface and improving the fidelity of audio transmission. Furthermore, when there is a spatial misalignment between the mounting position of the acoustic device 300 and the extension path of the groove 4021, the second through-hole 401 can serve as a transition channel, eliminating the need to modify the overall routing of the groove 4021 or the mounting position of the acoustic device 300. This effectively reduces the constraints on structural design and processing, and lowers manufacturing difficulty. Additionally, if there are minor processing errors on the mating surfaces of the groove 4021 and the acoustic device 300, the second through-hole 401 can accommodate the gaps caused by these errors, preventing air gap leakage and reducing the requirements for processing precision.
[0064] In the above scheme, the extension direction of the second through hole 401 can be parallel to the first direction mentioned above. One end of the second through hole 401 can penetrate the bottom of the groove 4021, and the other end can penetrate the surface of the first part 410 on the side opposite to the decorative cover 200. Optionally, in some embodiments of this application, the second through hole 401 extends along the thickness direction of the first bracket 400 to penetrate and connect the groove 4021.
[0065] To further improve the sealing performance of the electronic device, in another optional embodiment, the electronic device may also include a sealing component 700 and a second bracket 800. The sealing component 700, the acoustic device 300 and the second bracket 800 may all be disposed on the side of the first bracket 400 opposite to the decorative cover 200.
[0066] The sealing assembly 700 may include a first seal 710 and a second seal 720. The first seal 710 may be located between the first support 400 and the acoustic device 300. This can be understood as the first seal 710 being positioned between the first support 400 and the sound hole of the acoustic device 300, thereby sealing the sound hole of the acoustic device 300 and preventing dust and moisture from entering. Therefore, the first seal 710 is used to achieve a waterproof and dustproof seal for the acoustic device 300. To avoid affecting the acoustic function, the first seal 710 allows sound to pass through but not moisture and dust; therefore, the first seal 710 may be made of a breathable sealing material.
[0067] The second seal 720 may be disposed around the first seal 710. The second seal 720 may be an annular structure. The acoustic device 300 may be disposed on the second bracket 800, and the second bracket 800 and the acoustic device 300 may be located within the inner cavity of the housing 100. The second bracket 800 may be a motherboard bracket. The inner ring region of the second seal 720 may be disposed opposite to the acoustic device 300. The side of the second seal 720 facing away from the first bracket 400 may abut against the second bracket 800. Optionally, in some embodiments of this application, the second seal 720 abuts against the circumference of the acoustic device 300. The second seal 720 can achieve a seal between the second bracket 800 and the first bracket 400, thereby preventing sound leakage from the electronic device. The second seal 720 needs to isolate a sealed chamber between the first bracket 400 and the second bracket 800; therefore, the second seal 720 cannot leak sound, and thus, the second seal 720 needs to be made of sound-insulating material. Optionally, in some embodiments of this application, the first seal 710 is disposed around one end of the second through hole 401 away from the groove 4021, and the second seal 720 is disposed around the first seal 710 to form a concentric structure.
[0068] In this solution, the combined sealing method of the first seal 710 and the second seal 720 can not only further avoid the risk of the acoustic device 300 being blocked, but also avoid the risk of sound leakage from the electronic device, thereby further improving the acoustic performance of the electronic device.
[0069] In the above scheme, the first sealing element 710 can be a waterproof and breathable membrane 712.
[0070] In another alternative solution, such as Figure 17 As shown, the first sealing element 710 may include a first adhesive layer 711, a waterproof and breathable membrane 712, a second adhesive layer 713, and a sealing foam 714 stacked sequentially. The first adhesive layer 711 is used to bond with the first support 400, and the sealing foam 714 abuts against the acoustic device 300. In this design, the double-layer sealing effect of the waterproof and breathable membrane 712 and the sealing foam 714 can achieve good waterproof and dustproof performance.
[0071] In the above scheme, the second seal 720 can be a sealing ring made of silicone material.
[0072] In the above solution, the high pre-pressure of the second seal 720 will lift the decorative cover 200, causing it to float and resulting in poor assembly accuracy of the electronic device. Therefore, in another optional embodiment, such as... Figure 18 As shown, the second seal 720 may include an annular body 721 and an annular abutment portion 722. The annular abutment portion 722 may be disposed on the surface of the annular body 721 facing away from the device support. Both the annular body 721 and the annular abutment portion 722 may be disposed around the first seal 710, and the angle between the plane of the annular body 721 and the outer peripheral surface of the annular abutment portion 722 is an acute angle.
[0073] In this design, the angle between the surface of the annular body 721 and the outer peripheral surface of the annular abutment 722 is an acute angle. Therefore, the annular abutment 722 is easily compressed, thereby reducing the pre-pressure of the second seal 720, thus avoiding the risk of the decorative cover 200 floating up, and thus improving the assembly accuracy of the electronic device.
[0074] Optionally, the angle between the plane where the annular body 721 is located and the outer peripheral surface of the annular abutment 722 can be 50°. Of course, the angle between the plane where the annular body 721 is located and the outer peripheral surface of the annular abutment 722 can be other angles, which are not limited in this article.
[0075] Furthermore, the second seal 720 may also include an extending protrusion 723, which may be disposed on the outer peripheral surface of the annular body 721. The first bracket 400 may have a positioning recess 405 on the side opposite to the decorative cover 200, and at least a portion of the extending protrusion 723 may be located within the positioning recess 405. The second seal 720 and the first bracket 400 can be positioned and engaged by the extending protrusion 723 and the positioning recess 405. This design can further improve the assembly accuracy of the second seal 720 and the first bracket 400.
[0076] In one alternative embodiment, the decorative cover 200 may be provided with a positioning protrusion 206, which can engage with the inner edge of the first through hole 103. This embodiment can improve the assembly accuracy between the decorative cover 200 and the housing 100.
[0077] Furthermore, such as Figures 5 to 7 As shown, the electronic device may further include a third bracket 900, which can be attached to the inner surface 101 of the housing 100. The third bracket 900 can be connected to the decorative cover 200. In this solution, the third bracket 900 is a bracket disposed within the housing 100. The third bracket 900 can assist in the connection of the decorative cover 200, thereby improving the assembly strength between the decorative cover 200 and the housing 100, and thus improving the assembly reliability of the electronic device.
[0078] In the above scheme, the third bracket 900 and the inner surface 101 of the housing 100 can be bonded together with double-sided adhesive. The third bracket 900 and the decorative cover 200 can be connected by screws, rivets, or other components.
[0079] In the embodiments disclosed in this application, the decorative cover 200 and the housing 100 can be assembled to form a sound-guiding gap 620, thereby avoiding the risk of the acoustic device 300 being blocked. Simultaneously, the sound-guiding channel 610 formed by the first bracket 400 extends the sound-guiding path, further avoiding the risk of the acoustic device 300 being blocked. Furthermore, in conjunction with the aforementioned sealing assembly 700, waterproof and dustproof sealing performance is achieved. Therefore, the electronic device disclosed in this application not only solves the technical problem of the acoustic device 300 being blocked, but also ensures that the electronic device has an IP68 waterproof and dustproof rating, thus achieving good sealing performance.
[0080] The electronic device disclosed in the embodiments of this invention can be a smartphone, tablet computer, e-book reader, or wearable device. Of course, the electronic device can also be other devices, and the embodiments of this invention do not limit this. The embodiments of this application have been described above with reference to the accompanying drawings; however, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
