DETAILED DESCRIPTION

[0045] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0046] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0047] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0048] In related technologies, to meet the diverse needs of users, electronic devices can be configured with or without display capabilities, with or without communication capabilities, and so on. Electronic devices with different functions generally require different structural designs, resulting in different versions of the device. These structural differences between different versions of devices require different production lines and equipment for manufacturing, resulting in high costs.

[0049] Based on this, the present application provides an electronic device that is additionally provided with a middle frame, in which the main electronic components or devices can be mounted, and the circuit board is also mounted. The electronic device has high versatility. For different versions of the device, only some structural components need to be replaced, and most structural components can be shared, thereby reducing manufacturing costs.

[0050] For electronic devices with the same basic functions but different functions, the middle frame and the devices installed in the middle frame can be the same or basically the same, and the first shell and / or second shell with different structures can be configured. In this way, the overall structure of electronic devices of different models is not much different, and more structural parts (materials) can be shared. Most of the manufacturing steps and assembly steps are the same, which can save costs.

[0051] Please refer to Figures 1 to 20 The electronic device of the present invention is described below. The electronic device includes a housing, a middle frame 20, and a circuit board 31. The electronic device can be used to store a wearable device.

[0052] The housing includes a first shell 11 and a second shell 12. The first shell 11 and the second shell 12 are connected to each other to form an installation cavity. The middle frame 20 is disposed in the installation cavity, that is, the middle frame 20 is disposed between the first shell 11 and the second shell 12. The middle frame 20 is provided with a storage slot 21 for storing a wearable device. The circuit board 31 is disposed between the middle frame 20 and the second shell 12 and is mounted on the middle frame 20.

[0053] Optionally, the middle frame 20 is provided with a fixing and a charging contact, and the fixing may be, but is not limited to, a magnet. When the wearable device is placed in the storage slot 21, the wearable device can be retained in the storage slot 21 under the action of the fixing, and the charging contacts of the wearable device are docked with the charging contacts provided on the middle frame 20 to charge the wearable device through the electronic device. Exemplarily, the wearable device is an earphone 90, and the electronic device can be used as an earphone box (the earphone box is also called an earphone compartment), and the storage slot 21 is used to store the earphone 90. The electronic device can charge the earphone 90 when the earphone 90 is placed in the storage slot 21. In other embodiments, the wearable device may also be an electronic device that requires electricity, such as a smart ring or a smart watch body.

[0054] The electronic device of the present application is additionally provided with a middle frame 20. The middle frame 20 not only provides a storage position for the wearable device, but also provides an installation position for the circuit board 31 and other major electronic components. In this way, the middle frame 20 and the structural parts installed in the middle frame 20 constitute the core module of the electronic device. For electronic devices with display functions and those without display functions, the structures of the middle frame 20 and the devices installed in the middle frame 20 can be designed to be consistent or basically consistent, and use first shells 11 with different structures. For electronic devices with communication functions and those without communication functions, the structures of the middle frame 20 and the devices installed in the middle frame 20 can be designed to be consistent or basically consistent, and use second shells 12 with different structures.

[0055] Taking the example of an electronic device that can accommodate earphones 90, the earphone box in the related art installs structural parts such as the circuit board 31 and the battery 40 on the shell. If the shape and structure of the shell changes, the shape, size, installation position, and layout relationship of the structural parts originally installed on the shell, such as the circuit board 31 and the battery 40, also need to be adjusted accordingly. In this way, the structures of electronic devices with different functions and different models are quite different, and they need to be manufactured through different production lines, different production equipment, or different assembly steps, which is costly. In the present application, for electronic devices with the same basic functions but different functions, it is convenient to adopt a first shell 11 and / or a second shell 12 with different structures according to needs. Since the main structural parts such as the wearable device, the circuit board 31 and the main electronic components are installed and fixed on the middle frame 20, the change of the shell structure has no effect or little effect on the installation of the main structural parts. If the electronic device needs to add new functions, it only needs to make partial changes to the device structure, which is conducive to cost control.

[0056] Reference Figure 4 、 Figure 7 、 Figure 8 、 Figure 13 、 Figure 16 、 Figure 17 In one embodiment, the electronic device includes a battery 40, which is disposed on a side of the middle frame 20 close to the first housing 11 and electrically connected to the circuit board 31. The middle frame 20 is also provided with charging contacts, which are electrically connected to the circuit board 31 and are at least partially located within the receiving slot 21.

[0057] Optionally, the electronic device further includes a wearable device, which is an earphone 90. The earphone 90 has a storage state in which it is stored in the storage slot 21 and a removal state in which it is removed from the storage slot 21. The earphone 90 is also provided with charging contacts. When the earphone 90 is in the storage state, the charging contacts of the earphone 90 are electrically connected to the charging contacts of the middle frame 20, so that the earphone 90 can be charged by the electronic device.

[0058] It is understood that installing the battery 40 and circuit board 31 on opposite sides of the middle frame 20 effectively utilizes the larger mounting surfaces on both sides of the middle frame 20, stably mounting the larger battery 40 and circuit board 31. This creates a reasonable structural layout, with the middle frame 20 stably supporting the battery 40 and circuit board 31, reducing internal component sway and maintaining structural stability. Furthermore, the battery 40, circuit board 31, and related structural components, such as the charging contacts, are all mounted on the middle frame 20, facilitating wiring between the battery 40 and circuit board 31, and between the charging contacts and the circuit board 31 or battery 40. This allows for charging of the wearable device when placed in the storage slot 21.

[0059] In one embodiment, referring to Figure 5 、 Figure 7 、 Figure 16The middle frame 20 is provided with a mounting groove 22 on the side close to the first shell 11. The middle frame 20 is formed with a top notch of the mounting groove 22 on the side close to the first shell 11. During assembly, the battery 40 can be installed into the mounting groove 22 through the top notch. The middle frame 20 is provided with the mounting groove 22. The groove wall of the mounting groove 22 can limit the battery 40, improve the installation stability of the battery 40, and prevent the battery 40 from shaking and causing the battery 40 to loosen from the circuit board 31. In addition, other structures can also be installed beside the mounting groove 22. These other structures share the height space of the middle frame 20 with the battery 40, allowing the middle frame 20 to install, accommodate or place more structural components.

[0060] Optionally, refer to Figures 18 to 20 A first receiving groove 102 is defined between the first housing 11 and the middle frame 20. The first receiving groove 102 communicates with the mounting groove 22 through the top notch of the mounting groove 22. The first receiving groove 102 is located on the side of the mounting groove 22 facing away from the second housing 12. The first receiving groove 102 is used to reserve space to facilitate accommodating the display module 50 through the first receiving groove 102 when the electronic device needs to add a display function. Optionally, the first receiving groove 102 is closer to the first housing 11 than the mounting groove 22. Optionally, the planar area of ​​the first receiving groove 102 is larger than the planar area of ​​the mounting groove 22.

[0061] Among them, the first accommodating groove 102 can be configured in the following manner: a part of the middle frame 20 is recessed in the direction away from the first shell 11, and / or a part of the first shell 11 protrudes in the direction away from the middle frame 20, so that there is a first accommodating groove 102 between the first shell 11 and the middle frame 20.

[0062] The following describes an electronic device without a display function and an electronic device with a display function.

[0063] In one embodiment, referring to Figures 1 to 8 The electronic device does not have a display function, that is, the electronic device does not have a display module 50. For some users, there is no need to study or read documents, so the electronic device does not need to be equipped with a display module 50. Correspondingly, there is no need to open the first housing 11 to accommodate the display module 50.

[0064] Alternatively, please continue to refer to Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 A first cover plate 71 is disposed between the first housing 11 and the middle frame 20. The first cover plate 71 is mounted on the middle frame 20 and covers the top notch of the mounting slot 22 of the middle frame 20. When the first housing 11 is removed or not installed, the first cover plate 71 covers the top notch of the mounting slot 22, protecting the battery 40.

[0065] When the first receiving groove 102 is provided between the first housing 11 and the middle frame 20 (eg Figure 19 、 Figure 20 If the electronic device does not need to be equipped with a display module 50, the first cover plate 71 is placed in the first receiving groove 102 (as shown in FIG. Figure 4 、 Figure 5 As shown in the figure, the first cover plate 71 fills the space originally used to accommodate the display module 50. The first cover plate 71 supports the first shell 11 to avoid insufficient structural strength of the position of the first shell 11 corresponding to the first accommodating groove 102. The position of the first shell 11 corresponding to the first accommodating groove 102 is not easily dented by impact.

[0066] In another embodiment, referring to Figures 9 to 17 , the electronic device has a display function, and the electronic device is provided with a display module 50. For example, the wearable device is an earphone 90, and the electronic device has an earphone box function. For some users, if the electronic device has a display module 50, the display module 50 can be used to display text associated with the audio played by the earphone 90, providing learning functions, reading files and other functions. The combination of the audio played by the earphone 90 and the display function of the electronic device can provide users with a richer user experience. It should be noted that Figure 9 、 Figure 11 、 Figure 16 In the display module, "AA" is only used for display purposes.

[0067] Correspondingly, a first opening 111 is opened in the first shell 11, and the inside and outside of the shell are connected through the first opening 111. The display module 50 is at least partially arranged at the first opening 111. The display module 50 is installed and fixed to the first shell 11 and / or the middle frame 20 by gluing or other methods. The display module 50 is electrically connected to the circuit board 31.

[0068] Optionally, the display module 50 is mounted and fixed to the first housing 11. The display module 50 includes a glass cover 51, a display panel 52, and other components. The first housing 11 is provided with an inwardly extending surround inside the first opening 111. In other words, a mounting recess is defined between the inner side of the first opening 111 and the side of the surround facing away from the middle frame 20. The edge of the glass cover 51 is clipped into the mounting recess and secured to the surround by adhesive or other means. The display panel 52 is adhesively secured to the side of the glass cover 51 closest to the middle frame 20.

[0069] Optionally, when a first receiving groove 102 is provided between the first housing 11 and the middle frame 20 (eg Figure 18 Schematic diagram), the display module 50 is partially located in the first receiving groove 102 (as shown in FIG. Figure 14The electronic device also includes a buffer 41 disposed between the display module 50 and the battery 40. The buffer 41 may be, but is not limited to, foam. The buffer 41 prevents direct contact between the battery 40 and the display module 50, thereby protecting the display module 50 and the battery 40. It also limits the position of the display module 50 and the battery 40, maintaining a stable overall structure.

[0070] Optionally, a glass cover 51 is positioned within the first opening 111, and a display panel 52 is positioned within the first receiving groove 102. A flexible printed circuit board (FPC) is positioned on the side of the display panel 52 facing away from the first housing 11. The circuit board 31 disposed between the middle frame 20 and the second housing 12 serves as the mainboard, with the display panel 52 electrically connected to the mainboard via the FPC. If a buffer 41 is provided, it is positioned between the FPC and the battery 40, with one side of the buffer 41 abutting the FPC and the other side abutting the battery 40. The buffer 41 acts as a limiter on the FPC. The mainboard is a rigid circuit board 31, and the FPC is a flexible circuit board 31.

[0071] Optionally, the first shell 11 is further provided with a sound through hole beside the first opening 111. Through the provision of the sound through hole and the internal arrangement of electroacoustic devices, the electronic device provides the function of collecting sound or playing sound.

[0072] It is understandable that for electronic devices without display functions and electronic devices with display functions, the wearable device, the middle frame 20, and most of the structural parts installed on the middle frame 20 can be shared, saving costs. The only difference is that for electronic devices without display functions, the first shell 11 does not need to be hollowed out to form the first opening 111, and a first cover plate 71 can be added between the first shell 11 and the battery 40. For electronic devices with display functions, the first shell 11 needs to be hollowed out to form the first opening 111, and the first cover plate 71 is removed, leaving the space occupied by the first cover plate 71 for the display module 50.

[0073] In one embodiment, a plurality of mounting portions 23 are provided on a side of the middle frame 20 proximal to the second housing 12, and the circuit board 31 is mounted on the mounting portions 23 at various locations thereof. Optionally, the circuit board 31 is mounted on the mounting portions 23 using fasteners 80. In other embodiments, the circuit board 31 may also be mounted on the mounting portions 23 using a snap-fit ​​fastening mechanism.

[0074] Optionally, the mounting portion 23 is a stud disposed on the side of the middle frame 20 proximate to the second housing 12. Multiple studs may be spaced apart on the side of the middle frame 20 proximate to the second housing 12. For example, four studs may be disposed at positions corresponding to the four corners of the circuit board 31, and the four corners of the circuit board 31 are secured to the four studs via fasteners 80. The studs may be integrally formed with the middle frame 20 or may be insert-molded into the middle frame 20.

[0075] The following describes an electronic device without a SIM card and an electronic device with a SIM card.

[0076] In one embodiment, the electronic device does not have a SIM card and has relatively simple functions. For some users, they only need to use the electronic device as a charging compartment to store and charge wearable devices, and do not need to use the electronic device for calls, mobile data, etc., so the electronic device does not have a SIM card function.

[0077] Optionally, refer to Figure 15 The circuit board 31 is mounted on the mounting portion 23 by means of fasteners 80 . The side of the circuit board 31 close to the middle frame 20 abuts against the mounting portion 23 . The mounting portion 23 directly supports the circuit board 31 , and the circuit board 31 is stably mounted.

[0078] In another embodiment, the electronic device includes a SIM card, and the electronic device is more versatile. For some users, not only do they need to use the electronic device as a charging station for a wearable device, but they may also need to insert a SIM card into the electronic device. The SIM card is used for identity authentication and network access. When the SIM card is installed in the electronic device, mobile data can be used to access the Internet and / or make calls.

[0079] Optionally, refer to Figures 15 to 17 The electronic device also includes a mounting pad 60, which is disposed between the mounting portion 23 and the circuit board 31. When the circuit board 31 is mounted on the mounting portion 23 and thus mounted on the middle frame 20, the mounting pad 60 is located between the mounting portion 23 and the circuit board 31, so that the circuit board 31 and the mounting portion 23 do not directly contact each other. The provision of the mounting pad 60 increases the spacing between the surface of the circuit board 31 and the surface of the middle frame 20, which facilitates the accommodation of taller components. For example, in a case where the first housing 11 is located on the upper side and the second housing 12 is located on the lower side, the addition of the mounting pad 60 between the upper side of the circuit board 31 and the lower side of the middle frame 20 increases the spacing between the upper side of the circuit board 31 and the lower side of the middle frame 20 during the installation of the circuit board 31. This increases the spacing between the upper side of the circuit board 31 and the lower side of the middle frame 20 during the installation of the circuit board 31. This makes it less likely that components on the side of the circuit board 31 closest to the middle frame 20 will interfere with the components on the upper side of the circuit board 31 during installation.

[0080] If the electronic device does not need to be equipped with mobile data Internet access or phone call functions, the circuit board 31 does not need to be equipped with communication modules and other devices. In this way, when assembling the circuit board 31, the circuit board 31 can be abutted against the mounting portion 23, and the height requirement for the space reserved between the circuit board 31 and the middle frame 20 is relatively low.

[0081] Optionally, when a mounting pad 60 is provided between the mounting portion 23 of the middle frame 20 and the circuit board 31, the mounting pad 60 is provided with a through-hole, and the fastener 80 passes through the circuit board 31 and the through-hole of the mounting pad 60, and then connects to the mounting portion 23 of the middle frame 20. By providing a through-hole in the mounting pad 60, the fastener 80 can lock and secure the circuit board 31 to the mounting portion 23 of the middle frame 20 while pressing the mounting pad 60 between the circuit board 31 and the mounting portion 23 of the middle frame 20, thereby stabilizing the position of the mounting pad 60. Exemplarily, the fastener 80 is a screw, and the mounting portion 23 of the middle frame 20 is a stud. The screw passes through the through-holes of the circuit board 31 and the mounting pad 60 and is threadedly connected to the stud.

[0082] It should be noted that the fastener 80 may or may not contact the mounting pad 60 , as long as the mounting pad 60 is clamped between the circuit board 31 and the middle frame 20 , the distance between the circuit board 31 and the middle frame 20 can be maintained at a preset size.

[0083] The mounting pad 60 may be a seat formed by stamping, or may be a hard plastic part, a soft plastic part, a metal part, etc. In other embodiments, the mounting pad 60 may be pre-installed on the middle frame 20 or pre-installed on the circuit board 31 by gluing, positioning post installation, etc.

[0084] Alternatively, when an electronic device requires mobile data internet access or phone calls, it may be necessary to integrate more communication components or modules onto the circuit board 31. However, if the planar dimensions of the circuit board 31 are designed to be too large, they will not fit within the overall dimensions of the electronic device. Therefore, electronic components are arranged on both sides of the circuit board 31, that is, on both the side of the circuit board 31 closest to the middle frame 20 and the side facing away from the middle frame 20. This allows for the placement of more communication components or modules while also preventing the circuit board 31 from being too large. In this case, by adding a mounting pad 60 between the circuit board 31 and the mounting portion 23 of the middle frame 20, the gap between the surface of the circuit board 31 and the surface of the middle frame 20 can be increased to accommodate the electronic components on the side of the circuit board 31 closest to the middle frame 20.

[0085] Optionally, a shielding cover 33 is provided on the side of the circuit board 31 closest to the middle frame 20. The shielding cover 33 covers some electronic components on the side facing away from the circuit board 31. When communication modules, high-frequency circuit modules, and other components are arranged on the circuit board 31, the shielding cover 33 can prevent external electromagnetic interference. When the shielding cover 33 is provided, the spacing between the surface of the circuit board 31 and the middle frame 20 surface can be increased by adding a mounting pad 60 between the circuit board 31 and the mounting portion 23 of the middle frame 20 to accommodate the shielding cover 33.

[0086] In one embodiment, please refer to Figure 12 、 Figure 17A SIM card holder 32 is located on the side of the circuit board 31 facing away from the middle frame 20. This SIM card holder 32, also known as a Subscriber Identity Module Card Socket, is an interface on electronic devices for inserting a SIM card. It provides a slot for the SIM card, enabling the device to read and identify the information stored on the SIM card, including the user's phone number, contacts, text messages, call logs, and so on, thereby enabling communication and connection with the mobile network. Placing the SIM card holder 32 on the side of the circuit board 31 facing away from the middle frame 20 provides space for inserting the SIM card and prevents the middle frame 20 from blocking the SIM card from being inserted into the SIM card holder 32.

[0087] Correspondingly, to facilitate user insertion and removal of the SIM card, the second housing 12 is provided with a second opening 121, providing communication between the interior and exterior of the housing. The electronic device also includes a second cover 72, which is removably attached to the circuit board 31 or the second housing 12. This covers the second opening 121, protecting the components within the housing. To insert or remove the SIM card, the second cover 72 is removed, exposing the SIM card holder 32 through the second opening 121, allowing the user to insert or remove the SIM card.

[0088] Optionally, the circuit board 31 is provided with slots on four sides. When the second cover 72 is installed, the snaps provided on the four sides of the second cover 72 snap into the snaps on the four sides of the circuit board 31. In other embodiments, the second cover 72 can also be snap-mounted to the second housing 12. Optionally, the second cover 72 or the second housing 12 is further provided with a handle, which allows the user to easily remove the second cover 72 by snapping in the handle with their fingers.

[0089] Optionally, when the second housing 12 is provided with a second opening 121 and the second cover 72 is removably mounted on the second opening 121, a shielding piece 122 is further provided on the inner side of the second opening 121 of the second housing 12. The shielding piece 122 is connected to the second housing 12 and extends from the edge of the second opening 121 toward the inner side of the second opening 121. The shielding piece 122 is located on the side of the circuit board 31 facing away from the middle frame 20. The shielding piece 122 is used to shield the electronic components on the side of the circuit board 31 facing away from the middle frame 20. Due to the provision of the shielding piece 122, when the second cover 72 is opened, only the SIM card holder 32 is exposed from the second opening 121, and other electronic components are shielded by the shielding cover 33 or the shielding piece 122, thereby preventing users from accidentally touching other electronic components and improving safety.

[0090] The shielding piece 122 is integrally formed with the second shell 12 , or the shielding piece 122 is mounted on the second shell 12 by adhesive fixation, snap fixation, fastening with a fastener 80 , or the like.

[0091] In one embodiment, at least one shielding piece 122 is used to shield a BTB connector. The BTB connector is located on the side of the circuit board 31 facing away from the middle frame 20. The display module 50 is electrically connected to the BTB connector via an FPC.

[0092] In one embodiment, the wearable device is an earphone 90, and the storage slot 21 is used to store the earphone 90. The battery 40 and the circuit board 31 are correspondingly arranged on the upper and lower sides of the middle frame 20, the first shell 11 is the upper shell, and the second shell 12 is the lower shell. The upper shell and the lower shell cover the upper and lower sides of the middle frame 20 and are connected. In addition, the storage slots 21 are set on the left and right sides of the middle frame 20, and the installation slot 22 is located in the middle of the two storage slots 21. The left and right sides of the middle frame 20 respectively form side notches of the two storage slots 21, and the left and right storage slots 21 are used to store two earphones 90 respectively. Correspondingly, the left and right sides of the shell are respectively provided with a take-in and put-out port 101, and the take-in and put-out port 101 is aligned with the side notch of the storage slot 21. The storage slot 21 is connected to the outside of the electronic device through the take-in and put-out port 101. During use, two earphones 90 are placed into the two earphone slots 90 through the access openings 101 on the left and right sides of the electronic device. The earphones 90 are fixed in the storage slots 21 through magnetic attraction, snap-on fastening, or other methods to store the earphones 90. In this embodiment, the mounting slot 22 is located in the middle, and the storage slots 21 are located on the left and right sides, fully utilizing the space of the middle frame 20 to meet the installation and fixation requirements of the main structural components such as a battery 40, two earphones 90, the earphone 90 components corresponding to the two earphones 90 (the earphone 90 components include related structures for fixing the earphones 90, charging the earphones 90, and ejecting the earphones 90), and the circuit board 31.

[0093] The electronic device of the present application can be configured into at least two versions. The electronic device of the first version has no display module 50 and no SIM card, and the electronic device of the second version has a display module 50 and a SIM card. The basic structure of the electronic device is highly versatile, and it is convenient to adjust according to different functional requirements. For example, for the electronic device of the first version, a first cover plate 71 is set between the first shell 11 and the middle frame 20. Correspondingly, for the electronic device of the second version, the first cover plate 71 can be cancelled. For another example, for the electronic device of the first version, when installing the circuit board 31, the board surface of the circuit board 31 can directly abut the mounting portion 23 of the middle frame 20. Correspondingly, for the electronic device of the second version, a mounting pad 60 can be added between the circuit board 31 and the mounting portion 23. For different versions of electronic devices, the structural design is relatively reasonable.

[0094] Optionally, the electronic device of the present application may also be configured with a third version, such as Figures 1 to 8As shown in the figure, the structure of the third version is consistent with that of the first version, with the difference being that the first shell 11 and the second shell 12 of the electronic device in the first version are non-transparent shells, while the first shell 11 and the second shell 12 of the electronic device in the third version are transparent shells to provide a richer and more high-tech visual appearance. Correspondingly, in the third version of the electronic device, the first cover 71 disposed between the first shell 11 and the middle frame 20 can shield the battery 40 so that when viewed from the side of the first shell 11, the internal components can be seen to be beautiful and neat. Different patterns or colors can be configured on the side of the first cover 71 close to the first shell 11 according to different needs. Figures 6 to 8 As shown in the figure, a decorative plate 73 can be provided between the second shell 12 and the circuit board 31. The appearance of the decorative plate 73 simulates the circuit board 31. A number of protrusions can be formed on the decorative plate 73. The sizes and heights of the protrusions can be inconsistent. The protrusions are used to simulate electronic devices. In this way, when viewed from the side of the second shell 12, the decorative plate 73 with electronic devices can be seen. It has strong technology and is neat and beautiful compared to a real circuit board, without complicated wiring.

[0095] Of course, in other embodiments, the first cover plate 71 may be provided with protrusions to simulate electronic components. Alternatively, the decorative plate 73 may be a flat plate with patterns or colors printed on it. It should be noted that in the first version of the electronic device, the first cover plate 71 and the decorative plate 73 may also be omitted.

[0096] In this application, multiple versions of electronic devices can be provided by modifying local structures and molds. Compared with electronic devices without display functions and SIM card functions, the structural changes of electronic devices with display functions and SIM card functions are minimized, and the relevant structures of internal components such as the middle frame 20 and earphones 90 can be shared. Only a few structural components such as the first shell 11, the second shell 12, and the circuit board 31 need to be structurally adjusted, and a second cover plate 72 needs to be added. By modifying local structures and molds, the manufacturing of two versions of electronic devices can be met, which can save costs.
