Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here. In addition, the "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated with each other are in an "or" relationship.

[0012] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1 to Figure 16 The embodiment of the present application discloses an electronic device, which includes a housing 100 , a camera decoration 200 , a circuit board bracket 300 , a sound cover 400 and a speaker 500 .

[0014] The housing 100 provides a mounting base for other components of the electronic device. The housing 100 is provided with an inner cavity and a through hole 101 connected to the inner cavity. The inner cavity here can be used to install other components of the electronic device, such as the above-mentioned circuit board bracket 300, speaker 500 and other components. In addition, the housing 100 of different structures forms different components. For example, the housing 100 may include a front shell, a back cover and a middle frame 120 disposed therebetween. The above-mentioned inner cavity can be formed by the front shell, the back cover and the middle frame 120 disposed therebetween, and the through hole 101 can be opened on the back cover. For another example, the housing 100 includes a front cover and a back cover, and the aforementioned middle frame 120 can be formed on the front cover or the back cover, that is, the middle frame 120 can be integrally formed with the front cover or the back cover, and the back cover here can also be understood as a battery cover 110. Of course, the housing 100 can also be other structures, which are not limited in this article.

[0015] The camera decoration 200 is arranged on the housing 100 and covers the through hole 101. The camera decoration 200 is provided with light-transmitting holes 210 and mounting holes 220 that are spaced apart. At this time, the camera decoration 200 is provided with light-transmitting holes 210 and mounting holes 220 that are arranged opposite to the through hole 101. The light-transmitting holes 210 are used for light transmission. At this time, the lens of the camera module of the electronic device is arranged opposite to the light-transmitting holes 210. At this time, the external ambient light enters the lens of the camera module through the light-transmitting holes 210, thereby realizing the shooting function of the electronic device.

[0016] The sound hood 400 is covered on the mounting hole 220. At this time, the mounting hole 220 is used to realize the installation of the sound hood 400. A plurality of sound holes 401 arranged in an array are provided in the area of ​​the sound hood 400 opposite to the mounting hole 220. The sound hood 400 here can cover the port at one end of the mounting hole 220, that is, the sound hood 400 is not located in the mounting hole 220. Alternatively, at least a portion of the sound hood 400 can be filled in the mounting hole 220, and a portion of the sound hood 400 here can completely fill the mounting hole 220. The sound hole 401 is used to export audio signals from the electronic device to the outside of the electronic device.

[0017] The circuit board bracket 300 is arranged in the inner cavity, and the circuit board bracket 300 plays the function of protecting the related components on the circuit board 830. In addition, it can also be used to support the housing 100, specifically, it can be used to support the back cover to prevent the back cover from being pressed and collapsed, and it can also provide protection for the circuit board 830 during the reliability drop process. The circuit board 830 of the electronic device can be attached to the circuit board bracket 300. The circuit board 830 here can be the main board of the electronic device, and of course it can also be the sub-board of the electronic device. The specific role of the circuit board 830 is not limited in this article.

[0018] The speaker 500 is used to realize the acoustic performance of the electronic device, and the audio signal of the electronic device can be transmitted to the outside of the electronic device through the speaker 500. In the embodiment disclosed in the present application, the speaker 500 is arranged on the circuit board bracket 300, and the circuit board bracket 300 is provided with a sound guide channel 301. The speaker 500 is connected to a plurality of array-arranged sound outlet holes 401 through the sound guide channel 301. At this time, the sound signal emitted by the speaker 500 is transmitted to the position of the sound outlet hole 401 of the sound cover 400 through the sound guide channel 301, and then exported to the outside of the electronic device through the plurality of array-arranged sound outlet holes 401 on the sound cover 400. The sound guide channel 301 here serves as the front sound cavity of the speaker 500.

[0019] In the embodiment disclosed in the present application, the speaker 500 is arranged on the circuit board bracket 300, and the circuit board bracket 300 is provided with a sound guide channel 301, where the sound guide channel 301 is equivalent to the front sound cavity. At this time, the front sound cavity is enlarged by utilizing the circuit board bracket 300. The present application sets a sound cover 400 on the camera decoration 200 of the electronic device, so the electronic device of the present application also realizes the sound output from the back side of the electronic device. Compared with the solutions in the related art, the electronic device disclosed in the present application enlarges the front sound cavity by utilizing the circuit board bracket 300. Therefore, the acoustic performance of the electronic device can be improved.

[0020] In addition, the solutions in the related art need to increase the volume of the camera decoration 200 in order to increase the front sound cavity, which will inevitably lead to an increase in the diameter and thickness of the decoration, thereby causing the volume of the electronic device to increase. The electronic device in the present application uses a circuit board bracket 300 to increase the front sound cavity, thereby increasing the front sound cavity without affecting the volume of the electronic device, which is more conducive to the development of lightweight electronic devices.

[0021] In addition, the speaker 500 is disposed on the circuit board bracket 300, and the speaker 500 is far away from the sound enclosure 400, which is more conducive to waterproofing and dustproofing of the speaker 500. The sound enclosure 400 adopts a multi-hole sound structure, which is more conducive to the output of sound and avoids the risk of single hole clogging.

[0022] In another optional solution, the outer surface of the sound enclosure 400 may be provided with a hydrophobic structure. For example, a hydrophobic film may be attached to the outer surface of the sound enclosure 400, or a coating treatment may be performed, so as to further improve the waterproof performance of the electronic device.

[0023] In the above solution, the circuit board bracket 300 can be an integrated structural component. In this case, the sound guide channel 301 can be processed or cast on the circuit board bracket 300.

[0024] In another optional embodiment, the circuit board bracket 300 may include a first bracket 310 and a second bracket 320, and the second bracket 320 and the speaker 500 are both located on the side of the first bracket 310 away from the camera decorative member 200, and are arranged side by side on the first bracket 310. The first bracket 310 and the second bracket 320 can enclose a main channel 3011, and the first bracket 310 is provided with a first opening 3012 connected to the main channel 3011, and the first opening 3012 is arranged opposite to the sound cover 400. The speaker 500 is connected to a plurality of array-arranged sound holes 401 through the main channel 3011 and the first opening 3012 in turn. The main channel 3011 and the first opening 3012 here form the above-mentioned sound guide channel 301.

[0025] When the electronic device is producing sound, the audio signal emitted by the speaker 500 first enters the main channel 3011, then enters the first opening 3012 through the main channel 3011, and then is output to the outside of the electronic device through the plurality of sound outlet holes 401 arranged in an array after passing through the first opening 3012. Figure 8 The arrow L1 and Fig.15 As shown by arrow L3 in FIG.

[0026] In this solution, the sound guide channel 301 is formed by the first bracket 310 and the second bracket 320, so it is easy to process and manufacture the sound guide channel 301, thereby simplifying the manufacturing process of the circuit board bracket 300. In addition, the speaker 500 and the second bracket 320 are arranged side by side on the first bracket 310, so the speaker 500 is located on one side of the second bracket 320. At this time, the speaker 500 is not directly opposite to the sound cover 400, so to a certain extent, the risk of dust adhering to the diaphragm of the speaker 500 can be reduced, thereby improving the dustproof performance of the electronic device. In addition, the speaker 500 and the second bracket 320 are arranged side by side on the first bracket 310, which can reduce the stacking thickness of the circuit board bracket 300 and the speaker 500, so it can be helpful to further reduce the thickness of the electronic device.

[0027] In the above scheme, the diaphragm of the speaker 500 can be oriented toward one end of the sound guide channel 301, which can also be understood as the diaphragm of the speaker 500 is oriented toward the second bracket 320. Here, it can be understood that the speaker 500 is placed vertically. Alternatively, in another optional scheme, the diaphragm of the speaker 500 can be oriented toward the camera decoration 200. At this time, there is a certain gap between the diaphragm of the speaker 500 and the first bracket 310, so as to avoid interference with the first bracket 310 during the vibration of the diaphragm. Here, it can be understood as placing the speaker 500 horizontally.

[0028] In an optional solution, a receiving groove 313 may be provided on a side of the first bracket 310 facing away from the camera decorative piece 200, and the second bracket 320 and the speaker 500 may be located in the receiving groove 313. This solution can further reduce the stacking height between the speaker 500, the first bracket 310 and the second bracket 320, thereby being more conducive to the development of thinner and lighter electronic devices.

[0029] In order to further improve the dustproof and waterproof performance of the electronic device, in another optional embodiment, the electronic device may further include a waterproof and dustproof portion 600, which may be disposed in the sound guide channel 301. It can be understood here that the waterproof and dustproof portion 600 may cover a local area of ​​the sound guide channel 301. In this solution, the waterproof and dustproof portion 600 can resist dust and water vapor, thereby further improving the waterproof and dustproof performance of the electronic device, further avoiding the risk of the speaker 500 being blocked, and thus ensuring the reliability of the acoustic performance of the electronic device.

[0030] Optionally, the waterproof and dustproof part 600 may include but is not limited to structures such as an adhesive layer, a dustproof net, and foam. The adhesive layer here is used to achieve the bonding and fixing of the waterproof and dustproof part 600, the dustproof net is used to block dust, and the foam is used to absorb water vapor, and can also play a role in dustproofing. At this time, different waterproof and dustproof properties can be achieved through the combination of the adhesive layer, the dustproof net, and the foam. For example, the waterproof and dustproof part 600 has two layers of adhesive layers, a layer of dustproof net, and a layer of foam. The dustproof net and the foam are superimposed, and the dustproof net and the foam are located between the two layers of adhesive layers. The two layers of adhesive are used for bonding and fixing. Of course, the number of layers of the dustproof net and the number of layers of foam can also be multiple layers. The mesh number of the dustproof net here can be 370 mesh, or 380 mesh, and of course it can be other mesh numbers, which are not limited in this article.

[0031] Further, the waterproof and dustproof part 600 may include a first waterproof and dustproof net 610 and a second waterproof and dustproof net 620. The first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 may be respectively located on opposite sides of the first bracket 310. The first waterproof and dustproof net 610 may be located between the sound cover 400 and the first bracket 310. The first waterproof and dustproof net 610 may cover the first opening 3012. The first waterproof and dustproof net 610 here is crimped between the sound cover 400 and the first bracket 310. The first waterproof and dustproof net 610 is the first waterproof and dustproof barrier of the electronic device. The second waterproof and dustproof net 620 may be arranged between the first bracket 310 and the second bracket 320. The second waterproof and dustproof net 620 may cover the main channel 3011. The second waterproof and dustproof net 620 here is crimped between the first bracket 310 and the second bracket 320. The second waterproof and dustproof net 620 is the second waterproof and dustproof barrier of the electronic device.

[0032] like Figure 7As shown by the arrow L2 in FIG. 4 , dust and water vapor enter the electronic device through the sound outlet hole 401 on the sound outlet cover 400, and first need to pass through the first waterproof and dustproof net 610, and then need to pass through the second waterproof and dustproof net 620. At this time, the waterproof and dustproof performance of the electronic device can be further improved through two waterproof and dustproof barriers.

[0033] Optionally, the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 may both be composed of a bonding layer, a dustproof net, foam, etc. The specific structures of the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 are not limited herein.

[0034] In the above solution, the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 can be arranged in parallel along the plane where the first bracket 310 is located, that is, the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 are both arranged horizontally.

[0035] In another optional embodiment, the second waterproof and dustproof net 620 can be tilted relative to the plane where the second bracket 320 is located. In this solution, the tilt of the second waterproof and dustproof net 620 can prevent dust from gathering on the dustproof net. In addition, the second waterproof and dustproof net 620 is tilted to ensure the sound output cross-sectional area, which can reduce the thickness of the camera decorative part 200, further reduce the thickness of the electronic device, and further facilitate the development of thin and light electronic devices.

[0036] In another optional embodiment, if Fig. 9 and Fig.15 As shown, the second bracket 320 is provided with a first groove 3201, a second groove 3202, and a second opening 3203. The notch of the first groove 3201 and the notch of the second groove 3202 can both face the first bracket 310. The second groove 3202 can be located on the side of the first groove 3201 facing the speaker 500. The second opening 3203 can penetrate the sidewalls of the first groove 3201 and the second groove 3202. At this time, the first groove 3201 and the second groove 3202 can be connected through the second opening 3203. The notch of the first groove 3201 is arranged opposite to and connected to the first opening 3012, and the notch of the second groove 3202 can be connected to the speaker 500; wherein, the first groove 3201, the second groove 3202, and the second opening 3203 are all used to form the main channel 3011.

[0037] At this time, the first groove 3201 and the first bracket 310 form the first channel section of the main channel 3011, the second opening 3203 forms the second channel section of the main channel 3011, and the second groove 3202 and the first bracket 310 form the third channel section of the main channel 3011. At this time, the audio signal emitted by the speaker 500 is sequentially transmitted to the sound outlet 401 through the third channel section, the second channel section, the third channel section, and the first opening 3012, and then output to the outside of the electronic device through the sound outlet 401.

[0038] In this solution, the main channel 3011 is a three-section channel structure that is bent in sequence, which is more conducive to waterproofing and dustproofing of the sound guide channel 301. In addition, the bent multi-section channel structure can also play a role in increasing the front sound cavity, which is more conducive to improving the acoustic performance of the electronic device.

[0039] The present application discloses a specific structure of a second bracket 320. Of course, the second bracket 320 can also be other structures, which are not limited in this article. Specifically, the second bracket 320 can include a main body 321 and a side panel 322. The main body 321 can have adjacent first side surfaces 3211 and second side surfaces 3212. The first side surface 3211 can be arranged opposite to the first opening 3012, and the first side surface 3211 can be provided with a first groove 3201. The side panel 322 is located between the speaker 500 and the second side surface 3212. The side panel 322 can be connected to the main body 321. The side panel 322 is inclined in a direction away from the first side surface 3211. The side panel 322 and the second side surface 3212 can enclose a second groove 3202, and the second side surface 3212 is provided with a second opening 3203.

[0040] In this solution, the side plate 322 is tilted in a direction away from the first side surface 3211. The tilted side plate 322 has good flow conduction performance, thereby further improving the transmission flow conduction performance of the audio signal, thereby further improving the acoustic performance of the electronic device. In addition, the second bracket 320 disclosed in the present application has a simple structure and light weight, so it is more conducive to reducing the weight and manufacturing cost of the electronic device.

[0041] Furthermore, the distance between the second side surface 3212 and the side plate 322 gradually increases in the direction from the first bracket 310 to the second bracket 320. This solution can further improve the transmission and flow conduction performance of the audio signal of the electronic device, thereby further improving the acoustic performance of the electronic device.

[0042] In another optional solution, the second bracket 320 may further include a first support rib 323, and the first support rib 323 may be disposed between the main body 321 and the side plate 322. In this solution, the first support rib 323 can further improve the strength of the second bracket 320, thereby further improving the safety and reliability of the second bracket 320.

[0043] Optionally, the first supporting rib 323 may be disposed at the location of the first opening 3012 . In this case, the first supporting rib 323 may separate the first opening 3012 into two small openings disposed at intervals.

[0044] In another optional embodiment, if Figure 8 and 13 As shown, the first side surface 3211 may have a first annular pressing surface 3211a, and the first annular pressing surface 3211a may be arranged around the notch of the first groove 3201, and the second waterproof and dustproof net 620 may be pressed on the first annular pressing surface 3211a through the first bracket 310. The second waterproof and dustproof net 620 is arranged at the notch position of the first groove 3201, and the notch position of the first groove 3201 is the end of the main channel 3011 away from the speaker 500, so the second waterproof and dustproof net 620 in this solution is arranged at the end of the main channel 3011 away from the speaker 500. Therefore, this solution traps dust and water vapor at the far end of the main channel 3011.

[0045] In this solution, the second waterproof and dustproof net 620 can be pressed onto the first annular pressing surface 3211a through the first bracket 310. Since the first annular pressing surface 3211a is an annular structure, the second waterproof and dustproof net 620 is pressed on all sides, making the pressing of the second waterproof and dustproof net 620 more reliable and avoiding the risk of vibration of the second waterproof and dustproof net 620.

[0046] Furthermore, if Figure 8 and 13 As shown, the first annular pressing surface 3211a can be inclined toward the side away from the first bracket 310, that is, the first annular pressing surface 3211a is inclined toward the direction away from the first bracket 310. In the direction from the second groove 3202 to the first groove 3201, the distance between the first annular pressing surface 3211a and the groove bottom of the first groove 3201 gradually increases. Here, the bottom surface of the first groove 3201 can be a horizontal reference surface, so the closer the second bracket 320 is to the speaker 500, the greater the distance between the first annular pressing surface 3211a and the groove bottom of the first groove 3201, and the higher the position of the area corresponding to the first annular pressing surface 3211a, and the farther the second bracket 320 is from the speaker 500, the smaller the distance between the first annular pressing surface 3211a and the groove bottom of the first groove 3201, and the lower the position of the area corresponding to the first annular pressing surface 3211a. It can also be understood that the side of the second waterproof and dustproof net 620 facing the speaker 500 is closer to the sound enclosure 400 , while the side of the second waterproof and dustproof net 620 facing away from the speaker 500 is farther away from the sound enclosure 400 .

[0047] In this solution, the dust particles on the second waterproof and dustproof net 620 will roll toward the side of the second waterproof and dustproof net 620 away from the speaker 500 under the action of gravity, and the dust will fall on the side of the first groove 3201 away from the second opening 3203, which is more conducive to improving the dustproof performance of the electronic device. In addition, the audio information is derived from the inclined high position of the second waterproof and dustproof net 620, because the inclined high position is not easy to gather dust, so it is not easy to affect the acoustic performance of the electronic device.

[0048] In another optional embodiment, the first bracket 310 may be provided with a second support rib 311, at least a portion of the second support rib 311 may be located at the first opening 3012, and the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 are respectively supported on opposite sides of the second support rib 311. In this solution, the second support rib 311 can provide auxiliary support to the middle area of ​​the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620, thereby further avoiding the risk of vibration of the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620, thereby reducing the influence of the vibration of the first waterproof and dustproof net 610 and the second waterproof and dustproof net 620 on the acoustic performance of the electronic device.

[0049] Furthermore, a crimping protrusion 402 may be provided on one side of the sound cover 400 facing the first bracket 310, and the crimping protrusion 402 may press the first waterproof and dustproof net 610 against the second supporting rib 311. In this solution, the crimping protrusion 402 and the second supporting rib 311 can clamp the middle area of ​​the first waterproof and dustproof net 610, thereby further avoiding the risk of vibration of the first waterproof and dustproof net 610, thereby further improving the acoustic performance of the electronic device.

[0050] In another optional embodiment, the second waterproof and dustproof net 620 can also be arranged on a side of the main channel 3011 close to the speaker 500. Fig.15 and Fig.16 As shown, the second side surface 3212 may have a second annular pressing surface 3212a, which is arranged around the second opening 3203, and the second waterproof and dustproof net 620 is pressed on the second annular pressing surface 3212a through the first bracket 310. At this time, the second waterproof and dustproof net 620 is arranged on a side of the main channel 3011 close to the speaker 500.

[0051] In this solution, the second waterproof and dustproof net 620 can be pressed onto the second annular pressing surface 3212a through the first bracket 310. Since the second annular pressing surface 3212a is an annular structure, the second waterproof and dustproof net 620 is pressed on all sides, making the pressing of the second waterproof and dustproof net 620 more reliable and avoiding the risk of vibration of the second waterproof and dustproof net 620.

[0052] In addition, when the second bracket 320 has a first supporting rib 323, the middle area of ​​the second waterproof and dustproof net 620 can be mounted on the first supporting rib 323, thereby supporting the middle area of ​​the second waterproof and dustproof net 620, thereby further avoiding the risk of vibration of the second waterproof and dustproof net 620.

[0053] exist Fig.15 and Fig.16 In the illustrated solution, a third support rib 324 may extend from one side of the main body 321 facing the first opening 3012, and a crimping protrusion 402 may be provided on one side of the sound cover 400 facing the first bracket 310, and the crimping protrusion 402 may press the first waterproof and dustproof net 610 against the third support rib 324. In this solution, the third support rib 324 and the crimping protrusion 402 may abut and clamp the middle area of ​​the first waterproof and dustproof net 610, thereby avoiding the risk of vibration of the first waterproof and dustproof net 610, thereby further improving the acoustic performance of the electronic device.

[0054] In another optional solution, a first dust accumulation groove 3201a may be provided at the bottom of the first groove 3201, and the first dust accumulation groove 3201a may be arranged opposite to the first opening 3012. In this solution, dust entering the first groove 3201 may settle into the first dust accumulation groove 3201a at the bottom of the first groove 3201, thereby further preventing the dust from continuing to spread toward the speaker 500, thereby further improving the dustproof performance of the electronic device.

[0055] In another embodiment, the sound enclosure 400 may have a first area 421 and a second area 422, the first area 421 may be arranged around the second area 422, and the first area 421 may be provided with a plurality of sound holes 401 arranged in an array. As can be seen from the above, the plurality of sound holes 401 arranged in an array are provided in the area of ​​the sound enclosure 400 opposite to the mounting hole 220, so the first area 421 is arranged opposite to the mounting hole 220, and since the first area 421 is arranged around the second area 422, the second area 422 here is also arranged opposite to the mounting hole 220. The first bracket 310 may be provided with a second dust accumulation groove 312 arranged in parallel with the first opening 3012 on one side of the sound enclosure 400, the second dust accumulation groove 312 may be arranged opposite to the first area 421, and the second area 422 may be arranged opposite to the first opening 3012.

[0056] In this solution, the sound outlet holes 401 on the sound enclosure 400 are not directly arranged opposite to the first opening 3012, but are arranged alternately with the first opening 3012. At this time, after external dust enters the sound outlet holes 401, Fig. 9As shown by the arrow in , due to the effect of gravity, most of the dust particles will fall into the second dust accumulation groove 312 opposite to the area where the sound outlet 401 is located, thereby preventing a large amount of dust from directly entering the first opening 3012, which is more conducive to improving the dustproof performance of the electronic device.

[0057] In the above solution, a certain distance needs to be maintained between the first area 421 and the first bracket 310, so as to reserve a gap connected to the first opening 3012, thereby blocking the path of audio transmission.

[0058] In another optional solution, the sound cover 400 may include a fixing plate 410 and a raised portion 420. In the axial direction of the mounting hole 220, the orthographic projection of the raised portion 420 may be located within the orthographic projection of the fixing plate 410, and the orthographic projection area of ​​the raised portion 420 may be smaller than the orthographic projection area of ​​the fixing plate 410. The fixing plate 410 may be located between the camera decorative part 200 and the circuit board bracket 300, and the fixing plate 410 here is used to fix the sound cover 400. At least part of the raised portion 420 may be located in the mounting hole 220, and the raised portion 420 may be provided with a plurality of sound holes 401 arranged in an array. At this time, the above-mentioned first area 421 and the second area 422 are both areas on the raised portion 420.

[0059] In this solution, the area of ​​the fixing plate 410 is larger than the area of ​​the protrusion 420, so the fixing plate 410 can be buckled inside the housing 100, thereby avoiding the risk of the sound cover 400 falling. In addition, the protrusion 420 can be filled in the installation, which can help improve the appearance and beauty, and also help improve the dustproof and waterproof performance.

[0060] Optionally, when the sound enclosure 400 includes the protrusion 420 , the crimping protrusion 402 may be disposed on the protrusion 420 and located in the second region 422 .

[0061] In the above embodiment, the fixing plate 410 can be connected to the first bracket 310 by bonding, clamping, threading, etc. Of course, other connection methods can also be used, which is not limited in this document.

[0062] In the above scheme, the camera decoration 200 is usually attached to the battery cover 110. However, the camera decoration 200 is prone to tilting at the installation position during the assembly process, and there is a risk of the installation position being elevated. The elevated installation position of the camera decoration 200 is likely to affect the thickness of the electronic device and more likely to affect the waterproof and dustproof performance of the electronic device.

[0063] Based on this, in another optional embodiment, the camera decoration 200 may be provided with a first buckle 230, and the circuit board bracket 300 may be provided with a second buckle 302, and the camera decoration 200 and the circuit board bracket 300 may be buckled together through the first buckle 230 and the second buckle 302. In this solution, the camera decoration 200 and the circuit board bracket 300 are buckled together by using the first buckle 230 and the second buckle 302. At this time, a pulling force is applied to the camera decoration 200 toward the inside of the housing 100, so that the camera decoration 200 can be more closely attached to the battery cover 110, thereby avoiding the risk of the camera decoration 200 being installed at a high position, which is conducive to reducing the thickness of the electronic device and improving the waterproof and dustproof performance of the electronic device.

[0064] In the above embodiment, the electronic device disclosed in the present application may further include a lens 700, which may cover the side of the camera decorative element 200 away from the housing 100, and the lens 700 may be provided with an exposure hole 710, which may be arranged opposite to the mounting hole 220. The lens 700 may be made of materials such as transparent glass or transparent resin.

[0065] In an optional solution, the housing 100 may include a middle frame 120 and a battery cover 110, and the electronic device may further include a display module 810 and a mainboard cover 820. The middle frame 120 is arranged around the mainboard cover 820, and the display module 810 and the battery cover 110 are respectively located on opposite sides of the middle frame 120. The display module 810 here is used to realize the display function of the electronic device. The mainboard cover 820 is used to support components such as the mainboard and the battery. The above-mentioned circuit is located between the mainboard cover 820 and the battery cover 110.

[0066] In the above solution, the number of the light-transmitting hole 210 and the mounting hole 220 on the camera decorative member 200 can be one. Figure 1 As shown, the number of light-transmitting holes 210 can be multiple, and the number of mounting hole 220 can be one, and the multiple light-transmitting holes 210 can be arranged at intervals along the circumference of the mounting hole 220. Of course, the mounting hole 220 and the light-transmitting hole 210 can also be arranged in other ways, which is not limited in this article.

[0067] The electronic device disclosed in the embodiment of the present invention may be a smart phone, a tablet computer, an e-book reader or a wearable device. Of course, the electronic device may also be other devices, which is not limited in the embodiment of the present invention.
