Description

Technical Field

[0001] The present application relates to the field of antenna technology, and in particular to a decorative component of a camera module and an electronic device. Background Art

[0002] As the development of foldable screen mobile phones continues, the market demand for thinner and lighter electronic devices such as foldable mobile phones is getting higher and higher. Many manufacturers choose to reduce the number of antennas or compress the size of antennas on the middle frame of electronic devices to save more space and achieve thinner and lighter electronic devices.

[0003] However, if this setting is applied to foldable screen mobile phones and other fields, the antenna design will inevitably be carried out under the premise of antenna performance loss while maintaining an ultra-thin shape or reducing the number of antennas. The reason is that the narrower the frame or the fewer the number of antennas, the smaller the radiator area of the antenna will be, and the overall efficiency will be reduced. Furthermore, after the overall size of the electronic device becomes thinner, the antenna height clearance becomes very small, and the performance of antennas such as LDS and FPC will become very poor, resulting in problems such as poor signal communication during the use of electronic devices. Summary of the invention

[0004] The present application provides a decorative component of a camera module and an electronic device. The decorative component in the present application enables the antenna to be integrated with the camera module, so there is no need to find an additional location for the antenna, which is conducive to saving the antenna installation space.

Detailed implementation manners

[0046] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0047] With the emergence of high-thin and light mobile phones such as folding screen phones, manufacturers are facing an increasingly small assembly space. Many manufacturers choose to compress the size of the antenna assembly to provide a thinner and lighter electronic device, but this has led to a worse signal interaction performance of the electronic device.

[0048] Based on this, as Figures 1 to 2 shown, the present application provides an electronic device 10, including a decoration component 100 of a camera module 400, a housing assembly 200, a control main board 300, and a camera module 400. The control main board 300 is fixedly disposed in the housing assembly 200, and the decoration component 100 is fixedly disposed on the housing assembly 200.

[0049] Among them, as Figures 3 to 5As shown, the decorative assembly 100 includes a decorative plate 110, a first antenna 120 and a light-transmitting plate 130. Specifically, the decorative plate 110 includes an insulating layer 111 and a metal decorative layer 112 disposed on the insulating layer 111, and the decorative plate 110 is provided with a first hollow hole 113 that penetrates the insulating layer 111 and the metal decorative layer 112. The first antenna 120 is disposed on the decorative plate 110, and the first antenna 120 is insulated from the metal decorative layer 112 and is spaced apart from the first hollow hole 113. The light-transmitting plate 130 includes a plate body 131 and a light-shielding layer 132, and the plate body 131 is provided with a first light-transmitting area. The light-shielding layer 132 is attached to the plate body 131 and is arranged away from the first light-transmitting area. The light-transmitting plate 130 is covered on the decorative plate 110 so that the first antenna 120 is sandwiched between the first surface 114 and the plate body 131, and the first light-transmitting area and the first hollow hole 113 are arranged opposite to each other to form a light-transmitting portion. The light shielding layer 132 is disposed to cover the first antenna 120 .

[0050] The light-transmitting portion is exposed to the shell assembly 200 , and the camera module 400 is disposed between the control mainboard 300 and the decoration assembly 100 . The control mainboard 300 is communicatively connected with the camera module 400 , and the camera module 400 can receive light transmitted from the light-transmitting portion.

[0051] It can be understood that by utilizing the decorative component 100 of the camera module 400, the first antenna 120 is integrated into the metal decorative layer 112, so that there is no need to set too many antenna components at other positions of the electronic device 10 to enhance the signal interaction performance, which is beneficial to reducing the space for installing the antenna in the electronic device 10 and facilitating the electronic device 10 to be lightweight.

[0052] Further, generally, the camera module 400 is a key functional component of the electronic device 10 (such as a smart phone, tablet computer, etc.). As consumers have higher and higher demands for shooting, the camera module 400 is required to adopt a higher performance camera and chip structure. The camera module 400 is usually provided with a camera, and the camera is used by the optical sensor component and the motor. The electronic device 10 generally needs to be equipped with a communication antenna, a WIFI antenna, a Bluetooth antenna, and an NFC antenna. In the related art, the camera module 400 and the antenna component of the electronic device 10 are usually installed independently to ensure that no electrical signal interference is formed between them. The optical sensor component and the motor in the related art are more susceptible to interference from the electrical signal emitted by the antenna, and are prone to noise problems, uneven display and other effect problems after being interfered. At the same time, the radiation interference of the camera also has a great impact on the antenna. The medium and high frequency radiation generated by the camera component will affect the sensitivity of the antenna, resulting in a decrease in antenna performance, which is not conducive to improving the signal transmission efficiency of the electronic device 10.

[0053] Based on this, through the insulating layer 111 and through the insulating cooperation setting of the first antenna 120 and the metal decoration layer 112, it is possible to isolate the electrical signal interference between the first antenna 120 and the camera, and maintain the stable operation of both.

[0054] It should be noted that the metal decoration layer 112 in the above embodiment can be provided on any component of the electronic device 10 and can be selected according to different production requirements.

[0055] In one example, see Figures 2 to 3 As shown, the metal decoration layer 112 is welded to the control main board 300 of the electronic device 10, and the light-transmitting plate 130 at least partially protrudes from the control main board 300, so that the camera module 400 is partially protrudingly provided on the control main board 300 and the bottom plate of the housing assembly 200. At this time, the camera module 400 can be a rear camera, and the light-transmitting plate 130 is used as a lens to protect the camera module 400.

[0056] It should be noted that the shape of the decorative plate 110 can be various, such as a circular plate, a square plate, etc., and will not be overly limited here.

[0057] Specifically, in one embodiment, the decorative plate 110 further includes a first surface 114 and a second surface 115 that are oppositely arranged along the thickness direction of the decorative plate 110. At least a part of the first antenna 120 is provided on the first surface 114, and the light-transmitting plate 130 covers the first surface 114.

[0058] Among them, in order to further improve the radiation performance of the first antenna 120, see Figure 5As shown, in combination with any embodiment of the above decorative panel 110, the decorative component 100 further includes a graphite sheet 140 and a shielding layer 150. The graphite sheet 140 includes a first body insulatingly disposed on the second surface 115. Along the thickness direction of the metal decorative layer 112, the first body is overlapped with the first antenna 120. The shielding layer 150 is insulatingly disposed from the metal decorative layer 112, and the shielding layer 150 is sandwiched between the second surface 115 and the first body. It can be understood that the graphite sheet 140 has the function of insulation and shielding. With the arrangement of the graphite sheet 140, at least part of the first antenna 120, the metal decorative layer 112, the insulating layer 111, the shielding layer 150, and the first body (graphite sheet 140) are overlapped in sequence along the thickness direction. In this way, the cooperation of the insulating layer 111 and the shielding layer 150 can increase the clearance area of the first antenna 120, thereby increasing the radiation length and radiation quality of the first antenna 120 and optimizing the signal communication performance. Further, the graphite sheet 140 disposed behind the shielding layer 150 can serve as a signal bounce of the first antenna 120, which is beneficial to realizing the directional transmission of the antenna part and further strengthening the signal shielding effect between the first antenna 120 and the camera module 400. In addition, the graphite sheet 140 has a certain heat dissipation function. Disposed in the decorative component 100 of the camera module 400, it can help the camera module 400 dissipate heat and improve the service performance of the camera module 400.

[0059] It should be noted that the insulating layer 111 can be, but is not limited to, PBT material, and can also be materials such as plastics, and no further limitation is made here. Similarly, the shielding layer 150 can be, but is not limited to, PBT material, or a conductive cloth 151 or a structure such as a gap, and no further limitation is made here.

[0060] In one embodiment, in combination with Figures 4 to 6 As shown, the shielding layer 150 includes a conductive cloth 151, and a part of the conductive cloth 151 is electrically connected to the shielding case of the camera module 400. It can be understood that generally, although the arrangement of the graphite sheet 140 can increase the signal shielding performance between the camera module 400 and the first antenna 120, the graphite sheet 140 will also absorb a certain amount of signals from the first antenna 120, ultimately affecting the signal transmission effect of the first antenna 120. Based on this, through the arrangement of the conductive cloth 151, it is such that: along the thickness direction, a part of the conductive cloth 151 is overlapped between the first antenna 120 and the graphite sheet 140, so that the conductive cloth 151 can avoid excessive electrical absorption of the first antenna 120 by the graphite sheet 140 through the electrical connection with the shielding case, ensuring the signal transmission effect of the first antenna 120, and having both the signal shielding effect between the first antenna 120 and the camera module 400. In addition, the arrangement of the conductive cloth 151 can also provide a certain shielding effect on the antenna direction of the first antenna 120, so the signal shielding effect between the first antenna 120 and the camera module 400 can be improved.

[0061] It should be noted that the conductive cloth 151 in the above embodiments is based on a fiber cloth (generally a commonly used polyester fiber cloth), and after pre-treatment, an electroplated metal coating is applied to make it have metal characteristics and become a conductive fiber cloth. The conductive cloth 151 can be any one of a nickel-plated conductive cloth 151, a gold-plated conductive cloth 151, a carbon-plated conductive cloth 151, an aluminum foil fiber composite cloth, etc., and the appearance of the conductive cloth 151 can be plain weave or grid, etc.

[0062] It should be noted that the shielding case can be fixedly fitted with components such as the housing assembly 200 and the control main board 300 of the electronic device 10, and no excessive restrictions are imposed here. At the same time, the shielding case can be provided not only on the components of the electronic device 10, but also on the device assembly, etc.

[0063] Specifically, in a specific embodiment, the graphite sheet 140 is used for thermally cooperating with the first shielding case 160 of the camera module 400, and the first shielding case 160 is used for shielding the chip of the control main board 300.

[0064] In another specific embodiment, as Figure 8 shown, the decoration component 100 includes a first shielding case 160, and the first shielding case 160 is used for connecting with the control main board 300 to shield the chip of the control main board 300, and the graphite sheet 140 is thermally cooperated with the first shielding case 160.

[0065] In this way, through the thermal cooperation between the graphite sheet 140 and the first shielding case 160, it is beneficial to accelerate the heat dissipation speed of the control main board 300, thereby improving the operation stability of the chip in the control main board 300.

[0066] Combined with any of the above embodiments of the first antenna 120, along the thickness direction of the decorative board 110, as Figure 4 and Figure 7 shown, the first antenna 120 does not overlap with the metal decorative layer 112, and the minimum distance between the first antenna 120 and the conductive cloth 151 is L1, and L1≥0.44 mm. It can be understood that the non-overlapping arrangement of the first antenna 120 and the metal decorative layer 112 can avoid the blocking interference of the overlapping arrangement of the metal decorative layer 112 and the first antenna 120 on the emission direction of the first antenna 120, which is beneficial to ensuring the stability of the emission direction of the first antenna 120, thereby improving the signal emission effect of the electronic device 10. Further, a clearance area is formed between the first antenna 120 and the conductive cloth 151, and the minimum distance L1 of the clearance area is L1≥0.44 mm. This size can ensure that the first antenna 120 has sufficient clearance to achieve normal signal emission, and at the same time, the size will not be too large, which can reduce the matching size of the antenna, thereby being beneficial to the thin and light of the electronic device 10.

[0067] It should be noted that the first antenna 120 in the above embodiments can be designed in a plate shape, or a special design that matches the size of the decorative plate 110 and avoids interference, etc. There are no excessive restrictions here.

[0068] Combined with any of the embodiments of the first antenna 120 above, referring back Figure 4 and referring to Figure 9 as shown, the first antenna 120 includes a first radiator 121, and the first radiator 121 is disposed on the first surface 114. Along the thickness direction, the first body overlaps with the first radiator 121. In this way, by integrally disposing the first radiator 121 on the decorative plate 110, while ensuring antenna radiation, there is no need to provide too many antennas on the housing of the electronic device 10, so as to improve the thinness and lightness of the electronic device 10.

[0069] It should be noted that the feeding point of the first antenna 120 can be set on itself to achieve self-feeding, or it can be fed in cooperation with the control main board 300, or it can be fed in cooperation with other components of the electronic device 10 to achieve, etc. There are no excessive restrictions here.

[0070] In some embodiments, such as Figure 9 as shown, the first antenna 120 includes a first feeding branch 122 connected to the first radiator 121. The first feeding branch 122 passes through the decorative plate 110 and is insulated from the metal decorative layer 112. At least a part of the first feeding branch 122 is exposed on the second surface 115, so that the first feeding branch 122 is fed in cooperation with the control main board 300. In this way, the first feeding branch 122 penetrates through the insulating layer 111 and realizes feeding cooperation with the control main board 300, and the control main board 300 is shielded and disposed in the first shielding case 160, so that the first antenna 120 can be fed nearby, improving the integration performance of the decorative component 100 and being beneficial to the miniaturization and thinness and lightness of the electronic device 10.

[0071] It should be noted that the first antenna 120 can be grounded or not grounded, and there are no excessive limitations here.

[0072] Specifically, in one embodiment, referring back Figure 3As shown, the first radiator 121 is grounded in cooperation with the metal decoration layer 112. The metal decoration layer 112 includes a grounding portion 1121 exposed on the second surface 115. It can be understood that through the grounding cooperation between the first radiator 121 and the metal decoration layer 112, the first radiator 121 is grounded through the grounding portion 1121 exposed on the second surface 115. The grounding portion 1121 here can cooperate with the frame of the housing assembly 200, or can be grounded in cooperation with the control main board 300 (at this time, the control main board 300 can be cooperated with the rear plate of the housing assembly 200), etc. In this way, the setting of the grounding portion 1121 can enable the first antenna 120 to form a reflecting surface and improve the antenna performance. Among them, the setting of the grounding point of the first antenna 120 can be at any grounded position, such as the housing assembly 200 of the electronic device 10, etc., which is not limited here.

[0073] In one example, refer back to Figures 3 to 4 As shown, the grounding portion 1121 is used for grounding cooperation with the control main board 300. It should be noted that the number of the grounding portions 1121 can be one or more, and the setting position on the control main board 300 can be any position, which is not limited too much here. In this way, the grounding portion 1121 is used for grounding connection with the control main board 300, which is convenient for the grounding portion 1121 to contact the grounding layer on the main board to realize the grounding of the first antenna 120 after the decorative board 110 is fixed to the housing assembly 200, and the method is simple and reliable.

[0074] In a specific implementation manner, refer back to Figure 4 As shown, the grounding portion 1121 is a current strong point. It can be understood that the current strong point can be the edge position of the housing assembly 200. Specifically, the housing assembly 200 includes a middle frame assembly. The middle frame assembly includes a first side 11201 and a second side 11202 arranged oppositely, and a third side 11203 and a fourth side 11204 arranged oppositely. The third side 11203 is bent and connected to the first side 11201 and the second side 11202, and the fourth side 11204 is bent and connected to the first side 11201 and the second side 11202. The camera module 400 is arranged close to the first side 11201; the first antenna 120 is arranged close to the third side 11203. At least one current strong point is arranged on any one of the first side 11201, the second side 11202, the third side 11203 and the fourth side 11204. In this way, by setting the grounding portion 1121 at the position of the current strong point, it is beneficial to improve the radiation quality of the antenna assembly, thereby improving the signal transmission quality of the first antenna 120.

[0075] In another specific embodiment, the grounding portions 1121 include a plurality of them, which are arranged at intervals along the edge of the decorative plate 110 on the second surface 115. It can be understood that the arrangement of the plurality of grounding portions 1121 can improve the signal transmission quality of the first display. In addition, the reception portions are arranged at intervals along the edge of the decorative plate 110 on the second surface 115, so that grounding cooperation can be formed around the first antenna 120 to form an antenna transmission signal that diverges evenly.

[0076] Combined with any of the embodiments of the above-mentioned second surface 115, the second surface 115 is provided with an avoidance recess, and at least part of the graphite sheet 140 and the shielding layer 150 are arranged in the avoidance recess. In this way, the arrangement of the avoidance recess can provide an installation space, so that when the shielding layer 150 and the graphite sheet 140 are overlapped, the overlapping cooperation degree is higher, thereby improving the shielding quality between the first antenna 120 and the camera module 400.

[0077] In one embodiment, the first hollow hole 113 penetrates through the first surface 114 and the second surface 115. In this way, the first hollow hole 113 is used to cooperate with the camera module 400. By arranging the first hollow portion on the first surface 114 and the second surface 115, the camera module 400 can partially cover the edge through the metal decorative layer 112, and the blocking performance and aesthetic performance are better. In addition, through the arrangement of the insulating layer 111 on the second surface 115, the electromagnetic shielding effect between the camera module 400 and the first antenna 120 can be strengthened, and the generation of the conduction space can be reduced.

[0078] Further, in one example, see Figure 3 As shown, the decorative component 100 further includes an adhesive layer 170, and the light-transmitting plate 130 is adhered to the first surface 114 through the adhesive layer 170. In this way, the light-transmitting plate 130 is adhesively arranged on the first surface 114 through the adhesive layer 170. The setting is simple, convenient for processing, and reduces the damage to the light-transmitting plate 130 during the processing of the light-transmitting plate 130.

[0079] It should be noted that the positional relationship between the light-transmitting plate 130 and the metal decorative layer 112 can be flush or have a height difference, and no excessive restrictions are imposed here.

[0080] In some embodiments, see Figures 3 to 4As shown, the metal decoration layer 112 includes a frame body 1122 exposed from the insulating layer 111, and the frame body 1122 is arranged around the light-transmitting plate 130. In this way, the cooperation between the light-transmitting plate 130 and the frame body 1122 makes there be a certain height difference between the light-transmitting plate 130 and the insulating layer 111, so that there is a certain height difference for fitting and installing the camera module, especially the front camera module. Taking an example for illustration, the metal decoration layer 112 is integrally arranged at the bottom plate or the middle frame assembly of the housing assembly 200 (equivalent to forming a full-metal DECO at this time) to improve the appearance aesthetics. At the same time, the frame body 1122 is arranged around the light-transmitting plate 130. At this time, the light-transmitting plate 130 can be a protection plate (such as a display screen) of the screen of the electronic device 10, so that the camera module 400 and the decoration component 100 are integrally arranged on the middle frame or the bottom plate of the mobile phone, realizing the front camera function and also having the antenna communication function.

[0081] Combined with any one of the above embodiments of the decoration component 100, such as Figure 4 、 5 and Figure 9 shown, the decoration component 100 includes a second antenna 180 arranged on the decoration plate 110. The second antenna 180 is arranged at an interval from the first antenna 120, and the minimum distance between the second antenna 180 and the first antenna 120 is L2, and L2≥1.5 mm. It can be understood that the setting of the second antenna 180 can provide antenna radiation with another radiation frequency or another amplitude direction, which is beneficial to improving the antenna radiation performance of the electronic device 10. In addition, through the avoidance setting of the first antenna 120 and the second antenna 180, partial coupling can exist between the first antenna 120 and the second antenna 180 to improve the radiation performance of the antenna.

[0082] It should be noted that the above first antenna 120 can be but is not limited to a frame antenna, a WIFI antenna, a GPS antenna, an FPC antenna, etc. and their combinations. Similarly, the second antenna 180 can be but is not limited to an NFC antenna, a slot antenna or their combinations, etc.

[0083] In some embodiments, the first antenna 120 includes an FPC antenna. In this way, it can be understood that the setting of the FPC antenna enables it to be integrally arranged in the camera module 400, and there is no need to additionally set an antenna component to achieve the function, which is beneficial to improving the integration performance of the camera module 400 and beneficial to the thinning of the electronic device 10.

[0084] Further, in a specific embodiment, the second antenna 180 includes an NFC antenna. Herein, NFC (Near Field Communication), that is, near field communication technology, enables devices using NFC technology (such as mobile phones) to exchange data when they are close to each other. It is evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. By integrating the functions of an inductive card reader, an inductive card, and point-to-point communication on a single chip, mobile payment, electronic ticketing, access control, mobile identity recognition, anti-counterfeiting, and other applications can be realized using terminal devices. It can be understood that the NFC antenna has relatively low requirements for the antenna environment, has a simple structure, and the working frequency band does not cross with that of the camera module, so the two will not interfere with each other. Therefore, even if there is a partially non-insulated setting between the two, it will not overly affect the performance. Thus, the NFC antenna can be flexibly arranged without deliberate avoidance, saving more space and facilitating the miniaturization of the decoration component 100.

[0085] Combined with any of the embodiments of the second antenna 180 described above, as Figure 3 and Figure 9 shown, the second antenna 180 includes a second radiator 181, and the second radiator 181 is disposed on the first surface 114 of the decorative panel 110. In this way, by also integrally arranging the second antenna 180 on the decorative panel 110, it is beneficial to further reduce the space within the decoration component 100, thereby improving the thinness and lightness of the electronic device 10.

[0086] It should be noted that the feeding point of the second antenna 180 can be set at any position and can be selected according to different usage requirements, and no excessive limitation is made here.

[0087] In some embodiments, the second antenna 180 includes a second feeding stub 182 connected to the second radiator 181. The second feeding stub 182 passes through the decorative panel 110 and is insulated from the metal decorative layer 112. At least a part of the second feeding stub 182 is exposed on the second surface 115 so that the second feeding stub 182 cooperates with the control main board 300 for feeding. It can be understood that through the setting of the second feeding stub 182, the second feeding stub 182 cooperates with the control main board 300 for feeding, which can reduce the feeding size burden of the second radiator 181 and does not need to be set too large or too long. Only by passing through the second feeding stub 182 can the feeding cooperation with the control main board 300 be realized, which is beneficial to the miniaturization of the decoration component 100 and the thinness and lightness of the electronic device 10.

[0088] It should be noted that the second radiator 181 can be grounded or not grounded, and the grounding position can be selected according to different production requirements, and no excessive limitation is made here.

[0089] In one embodiment, referring back to Figure 3 As shown, the second radiator 181 is grounded in cooperation with the metal decorative layer 112, and the metal decorative layer 112 includes a grounding portion 1121 exposed on the second surface 115. In this way, the second radiator 181 is grounded through the first surface 114 and the insulating layer 111, and the insulating layer 111 can be provided to shield some antenna signals that affect the electrical signals of the camera module 400, thereby improving the operating stability between the second antenna 180 and the camera module 400.

[0090] It should be noted that the type of the camera in at least one camera module 400 is at least one of a wide-angle lens, a standard lens, a telephoto lens, a zoom lens, a pinhole lens, a rear lens, and a front lens.

[0091] Specifically, the camera module 400 at least includes a lens, a photosensitive chip, a driving chip, and an output structure, and the output structure can be electrically connected to the chip of the control main board 300 for signal transmission (such as the conversion and transmission of A / D signals). The camera assembly can also include a voice coil motor to achieve zooming.

[0092] In some embodiments, the light-transmitting portion can also be used to install structural elements such as a distance sensor and a flash device to meet the normal working requirements of the camera module. And through the function of the first shielding case 160 (equivalent to a metal shielding member) in the above embodiments, the shielding effects of the sensing element, the flash element, the photosensitive chip, and the voice coil motor are realized, avoiding electrical signal interference.

[0093] It should be noted that the first feeding stub 122 and the second feeding stub 182 in the above embodiments can be, but are not limited to, stub antennas, and can also be feeding spring antennas. Specifically, in some embodiments, the camera module 400 further includes at least two feeding spring antennas. Among them, at least two feeding spring antennas include a first feeding spring antenna and a second feeding spring antenna. The first feeding spring antenna is fed and connected to the first radiator 121 (which can also be an FPC antenna), the second feeding spring antenna is fed and connected to the NFC antenna, and the first feeding spring antenna and the second feeding spring antenna are used to connect to the main board chip battery core of the terminal device.

[0094] In the actual production and installation process, in order to improve the installation performance, the following method can be used for operation, and the following uses an example for illustration:

[0095] Referring to Figure 4 As shown, first extend the feeding stub of the FPC antenna from the opening of the insulating layer 111 (which can be made of PBT material) to the back for fixed installation; then fix and install the NFC antenna to the insulating layer 111 or the light-shielding layer 132, and finally, after pasting the adhesive, complete the installation of the light-transmitting plate 130 (i.e., the protective plate of the lens or the screen).

[0096] After attaching the graphite sheet 140 to the metal shielding member first, the conductive cloth 151 is then attached to the graphite sheet 140. The metal shielding member is fixed to the main board chip by welding or bonding, etc., so that the graphite sheet 140 and the conductive cloth 151 are located on the main board in the thickness direction.

[0097] Furthermore, through the cooperation of the feeding stub and the main board chip, and the feeding cooperation between the NFC antenna and the main board chip, the components on the final metal shielding member and the components on the light-transmitting plate 130 are integrally arranged to form the decorative component 100.

[0098] Further, through the tests of the operators in this application, it can be obtained that during the use of the electronic device 10 with the integrated arrangement of the camera module 400 and the antenna, the mutual inductance efficiency between the two reaches about -8 dB, and when applied to a folding screen mobile phone, the unfolding and closing performance is basically the same and the performance is stable, meeting the network access requirements.
