DETAILED DESCRIPTION

[0043] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0046] In the related art, some electronic devices are equipped with antennas. There are currently two difficulties in setting antennas in electronic devices: First, the antenna is set in the device casing, but the device casing is an exterior part. After the antenna is set in the casing, it is necessary to cover and protect the antenna position with spray materials, which requires at least three sprayings and three bakings, which is costly. Second, if the antenna is set inside the device, there are many interference sources such as circuit boards, batteries, and other electronic devices inside the electronic device, and the environment is complex, which is not conducive to the performance of the antenna.

[0047] The present application provides an antenna design scheme for an electronic device. The electronic device is provided with an antenna bracket, and the antenna bracket is arranged inside the electronic device housing. The antenna is arranged on the antenna bracket, and there is no need to arrange the antenna in the electronic device housing, and there is no need to spray and bake the housing, thereby reducing the cost of the housing.

[0048] The layout position of the antenna bracket of the electronic device of the present application can minimize the interference of the battery, display module and other electronic devices inside the electronic device on the antenna signal reception and transmission. At the same time, when the electronic device is placed on a desktop for use, the mobile communication antenna is located at the front side of the internal space of the electronic device, and the mobile communication antenna is away from the user to obtain a better antenna signal.

[0049] Please refer to Figures 1 to 15 , the electronic device of the present application is described in more detail below.

[0050] The electronic device includes a housing 10, a circuit board 20 and an antenna bracket 30. The housing 10 has an inner cavity, and the circuit board 20 and the antenna bracket 30 are arranged in the inner cavity. The antenna 34 is arranged on the antenna bracket 30, and the antenna 34 is electrically connected to the circuit board 20. The circuit board 20 is arranged horizontally, and the antenna bracket 30 is arranged vertically, and the antenna bracket 30 is arranged on the front side and / or the rear side of the circuit board 20; when the electronic device is placed flat on a desktop, the circuit board 20 is parallel or substantially parallel to the desktop, and the antenna bracket 30 extends from top to bottom.

[0051] For ease of understanding, the x-direction, y-direction and z-direction of the electronic device are illustrated in the drawings. The x-direction, y-direction and z-direction are perpendicular to each other. The board surface of the circuit board 20 is parallel to the x-direction and the y-direction. The thickness direction of the circuit board 20 is consistent with the z-direction. The antenna bracket 30 extends along the z-direction. The lateral space in the z-direction of the circuit board 20 is used to accommodate the main electronic components of the electronic device. For example, the electronic components such as the battery 71 and the display module 50 of the electronic device are arranged on the side of the circuit board 20 in the z-direction.

[0052] In this embodiment, the x direction of the electronic device is the left and right direction of the device, the y direction is the front and back direction of the device, and the z direction is the up and down direction of the device. The electronic device has a usage state in which it can be placed flat on a desktop. At this time, the lower side of the electronic device is in contact with the desktop, the rear side of the electronic device faces the user, and the front side of the electronic device is away from the user.

[0053] The electronic device of the present application is provided with an antenna bracket 30 inside the shell 10, and the antenna 34 is provided on the antenna bracket 30. In this way, the antenna 34 does not need to be provided on the shell 10, and the appearance, structure, and shape of the shell 10 are not affected. There is no need to spray and bake the shell 10 multiple times, thereby reducing the cost of the shell 10. In addition, the antenna 34 is provided on the antenna bracket 30 inside the shell 10. When the antenna 34 needs to be replaced or upgraded, it is only necessary to open the device shell 10 and replace the antenna 34 on the antenna bracket 30. There is no need to replace or overhaul the entire shell 10. The antenna 34 is not easily physically damaged due to wear and tear, and has high safety.

[0054] In the electronic device of the present application, the circuit board 20 is arranged horizontally, and the upper and lower sides of the circuit board 20 (i.e., the two sides in the thickness direction of the circuit board 20) have space for installing electronic devices. By arranging the antenna bracket 30 on the front and / or rear side of the circuit board 20, the antenna bracket 30 can avoid the space reserved for installing other electronic devices on the upper and lower sides of the circuit board 20, which can not only make the layout of electronic devices more compact, but also allow the antenna bracket 30 to avoid the space where electronic devices are densely concentrated, reduce the interference of internal electronic devices on the signal reception and transmission of the antenna 34 on the antenna bracket 30, and improve the performance of the antenna 34. In addition, the antenna bracket 30 is arranged vertically, and the antenna bracket 30 extends a certain distance from top to bottom. The antenna bracket 30 can provide a larger layout area and improve the performance of the antenna 34.

[0055] Compared with the solution of horizontally setting the antenna 34 on the lower side of the display screen, in this embodiment, the antenna 34 bracket is vertically set and set in the front or rear area inside the shell, which is easy to meet the clearance requirements of the antenna 34, and has a simple structure and low cost.

[0056] In one embodiment, the electronic device includes a display module 50, which is disposed on one side of the circuit board 20 in the thickness direction, and the display module 50 is electrically connected to the circuit board 20. Figure 1 As shown in the figure, when the electronic device is placed flat on the desktop, the user can see the content displayed by the display module 50. Since the antenna bracket 30 is arranged on the front or rear side of the circuit board 20, the user uses the left or right hand to touch the display module 50. In most cases, only the left and right areas of the electronic device are blocked, and the upper space of the antenna 34 layout area is less blocked. The layout position of the antenna bracket 30 in this application reduces or avoids the user's touch operation of the display module 50 affecting the antenna 34 signal. Figure 2 As shown, when the user's left and right hands hold the holding space at the left and right ends of the electronic device, since the antenna bracket 30 is arranged on the front and rear sides of the internal space of the shell 10, the obstruction of the antenna 34 arranged on the antenna bracket 30 when the left and right hands are holding is greatly reduced, and the user's holding operation has less impact on the antenna 34 signal.

[0057] Optionally, the electronic device further includes a cover plate 60, which is disposed on the upper side of the display module 50 to protect the display module 50. The cover plate 60 may be a glass cover plate. Figures 1 to 3 In the figure, the "AA" indicated on the cover is used as an indication of the display content of the display module.

[0058] Optionally, the front side of the circuit board 20 is the front side of the board, and the back side of the circuit board 20 is the back side of the board. The back side of the display module 50 is the back side of the screen, and the front side of the display module 50 is the front side of the screen. The front side of the circuit board 20 is provided with an antenna bracket 30, which means that a bracket is provided next to the front side of the board; the back side of the circuit board 20 is provided with an antenna bracket 30, which means that an antenna bracket 30 is provided next to the back side of the board. When the electronic device is placed flat on the desktop, the display module 50 is located on the side of the electronic device away from the desktop, the back side of the board and the back side of the screen face the user, and the front side of the board and the front side of the screen face away from the user.

[0059] In one embodiment, an antenna bracket 30 is provided on the front side of the circuit board 20, the antenna bracket 30 provided on the front side of the circuit board 20 is a first antenna bracket 301, and the antenna 34 provided on the first antenna bracket 301 is a mobile communication antenna. Optionally, the mobile communication antenna 34 is a 4G antenna. In other embodiments, the mobile communication antenna may also be a 3G antenna or a 5G antenna.

[0060] In one embodiment, one or more antenna brackets 30 are provided on the rear side of the circuit board 20, one of the antenna brackets 30 provided on the rear side of the circuit board 20 is a second antenna bracket 302, and the antenna 34 provided on the second antenna bracket 302 is one of a local area network communication antenna (such as a WIFI antenna), a satellite navigation antenna (such as a GPS antenna), an Internet of Things antenna (such as an IOT antenna), and a short-range wireless communication antenna (such as a Bluetooth antenna).

[0061] In one embodiment, the electronic device is a learning machine, and antenna brackets 30 are provided on the front and rear sides of the circuit board 20. A 4G antenna is provided on the antenna bracket 30 provided on the front side of the circuit board 20, and a WIFI antenna is provided on the antenna bracket 30 provided on the rear side of the circuit board 20. Based on the 4G antenna, the learning machine can access the Internet through the 4G mobile network without a WIFI network, allowing the learning machine to conduct online learning, browse web pages, download learning materials, etc. in any place covered by 4G signals, and can also conduct voice or video calls, which is convenient for students to communicate with teachers, classmates, and parents remotely, solve problems in learning or daily communication. Based on the WIFI antenna, users can download materials, make voice or video calls, etc. through the wireless WIFI network, and can also connect the learning machine with the smart home and use the learning machine to control smart devices at home, such as lights and audio.

[0062] In this embodiment, a 4G antenna is arranged on the front side of the circuit board 20 through an antenna bracket 30, and a WI FI antenna is arranged on the rear side of the circuit board 20 through an antenna bracket 30, which not only meets the needs of the learning machine for online learning in different network environments, but also avoids the positions where fingers on the left and right sides of the learning machine are gripped or operated, so as to obtain a better antenna 34 signal. On the second aspect, the 4G antenna (mobile communication antenna) with higher signal requirements is arranged on the front side. When the user uses the learning machine, the antenna bracket 30 of the 4G antenna is located on the side away from the user, and the 4G antenna faces forward, which has little effect on the signal of the 4G antenna, and the performance of the 4G antenna is more stable. In addition, the WI FI antenna (local area network communication antenna) is arranged on the rear side. Although the WI FI antenna will face the human body and interfere with the signal to a certain extent, the WIFI antenna does not have too high signal requirements, and such a layout can also meet the signal requirements.

[0063] In other embodiments, the antenna bracket 30 may be disposed only on the front side of the circuit board 20 , or only on the rear side of the circuit board 20 .

[0064] In one embodiment, the antenna 34 is an LDS antenna. In other words, the antenna 34 is arranged on the antenna bracket 30 by the LDS process. Among them, ordinary mobile phone antennas are installed on the motherboard of the mobile phone, and the LDS antenna technology is the laser direct structuring technology. The computer is used to control the movement of the laser according to the trajectory of the conductive pattern, and the laser is projected onto the molded three-dimensional plastic antenna bracket 30. In a few seconds, the circuit pattern is activated. In short, on the molded plastic bracket, the metal antenna pattern is directly plated on the bracket by laser technology. The advantage of setting the antenna 34 on the antenna bracket 30 by the LDS process is that the antenna 34 is more stable, and the interference of internal components near the circuit board 20 can be reduced or avoided. At the same time, more design space can be saved, making the electronic device structure more compact.

[0065] Optionally, refer to Fig.14 The side of the antenna bracket 30 facing away from the circuit board 20 is the bracket outer surface 311, and the antenna 34 is arranged on the bracket outer surface 311. Among them, the circuit pattern of the main part of the antenna 34 (such as the radiation unit circuit pattern, etc.) is arranged on the bracket outer surface 311.

[0066] For example, the antenna 34 is laser engraved on the outer surface 311 of the bracket by LDS. Fig.11 , Fig.12 , Fig.13As shown in the figure, when the antenna bracket 30 is installed inside the housing 10, the antenna bracket 30 wraps the electronic devices (such as the battery 71, the display module 50, the interface, etc.) inside the antenna bracket 30, and the antenna 34 is located outside the antenna bracket 30. The antenna 34 and the nearest components are isolated by at least the thickness of the bracket, and the antenna 34 has a good isolation effect from other devices, and other devices have little interference with the antenna 34. In addition, the antenna 34 is arranged on the bracket outer surface 311 of the antenna bracket 30, and the signal of the antenna 34 is emitted from the outside of the electronic device, and the signal transmission effect is good.

[0067] In one embodiment, the antenna 34 and the circuit board 20 are electrically connected by direct physical contact. A protruding frame 32 is provided on one side of the antenna support 30 close to the circuit board 20; the protruding frame 32 is located on one side of the circuit board 20 in the thickness direction. In other words, the protruding frame 32 is located on the upper side or the lower side of the circuit board 20. Specifically, the protruding frame 32 is located beside the board surface of the circuit board 20 where the components are provided. Fig.15 A feeding point 341 is provided on one side of the extended frame portion 32 close to the circuit board 20. Correspondingly, the circuit board 20 is provided with an electrical connector 21. The feeding point 341 contacts and is electrically connected to the electrical connector 21, so that the antenna 34 is electrically connected to the circuit board 20, and the signal transmission between the antenna 34 and the circuit board 20 is realized. The feeding point 341 is used to transmit the electrical signal from the circuit board 20 to the radiating unit of the antenna 34, or to transmit the electrical signal received by the radiating unit of the antenna 34 back to the circuit board 20.

[0068] It should be noted that Fig.14 The shaded area in the figure is only used to illustrate the circuit pattern of the antenna 34. In a specific application, the antenna 34 of other shapes and layouts can be selected according to the performance of the antenna 34. Fig.15 The shaded area is only used to illustrate the setting method of the feed point 341 of the antenna 34. In specific applications, the feed point 341 can also be set in other ways. Optionally, the electrical connector 21 on the circuit board 20 is a Pogo pin, which is also called a spring pin. It is an electrical connector 21. It mainly consists of three basic components: a needle shaft, a spring, and a needle tube. After being pre-pressed by a precision instrument, a spring-type probe is formed. Pogo pin is used for current and signal transmission. Using Pogo pin as an electrical connector 21, the Pogo pin can be pressed tightly on the feed point 341 of the antenna 34 of the extended frame 32 to achieve electrical connection without the need for complex operations such as welding, and the contact and docking are stable.

[0069] In other embodiments, the electrical connector 21 on the circuit board 20 for connecting to the antenna 34 is a solder pad, a pin, etc.

[0070] Optionally, the antenna bracket 30 includes a bracket body and a protruding bracket portion 32. The aforementioned antenna bracket 30 is vertically arranged and the antenna bracket 30 is arranged on the front side or the rear side of the circuit board 20, which means that the bracket body of the main part of the antenna bracket 30 is vertically arranged and the bracket body 31 is arranged on the front side or the rear side of the circuit board 20.

The feeding point 341 of the antenna 34 is arranged on the side of the extended bracket portion close to the board surface of the circuit board 20. Among them, the main part of the antenna 34 can be formed on the bracket body by LDS, and the feeding point 341 of the antenna 34 can be formed on the protruding bracket portion 32 by LDS.

[0071] In other embodiments, the antenna bracket 30 may also only include a bracket body that is vertically arranged and extends up and down, without an extended bracket portion 32. Correspondingly, a cable is added to connect the feed point 341 of the antenna 34 with the electrical connector 21 on the circuit board 20 for connecting the antenna 34.

[0072] In one embodiment, please refer to Figures 4 to 13 The electronic device also includes a middle frame 40, which is arranged inside the housing 10. The middle frame 40 is arranged on the upper side or the lower side of the circuit board 20, that is, the middle frame 40 is arranged on one side in the thickness direction of the circuit board 20. The setting of the middle frame 40 can provide an installation and fixing position for internal electronic components. Exemplarily, the circuit board 20 is fixed to the middle frame 40 by screw locking or other installation methods. In this way, when assembling the electronic device, the internal electronic components and the middle frame 40 can be assembled together to form a module, and finally the housing 10 can be installed on the outside.

[0073] Optionally, when the middle frame 40 is disposed on the upper side or the lower side of the circuit board 20, the antenna bracket 30 disposed on the front side of the circuit board 20 is located on the front side of the middle frame 40, and the antenna bracket 30 disposed on the rear side of the circuit board 20 is located on the rear side of the middle frame 40.

Figure 7 , Figure 8 In the figure, it is shown that four second clamping parts 33 are arranged on the inner side of the bracket. The plurality of second clamping parts 33 surround the protruding bracket part 32, so that when the plurality of second clamping parts 33 located around the feed point 341 of the antenna 34 are clamped and buckled with the middle frame 40, the feed point 341 of the antenna 34 can be accurately aligned with the electrical connector 21 of the circuit board 20 to achieve reliable docking.

[0076] It should be noted that the number of the first clamping parts 41 provided on the middle frame 40 is consistent with the number of all the second clamping parts 33 in all the antenna brackets 30. For example, an antenna bracket 30 is provided on the front and rear of the circuit board 20, and four second clamping parts 33 are provided on the inner side of each antenna bracket 30, and four first clamping parts 41 are provided on the front and rear sides of the middle frame 40, respectively.

[0077] In other embodiments, the antenna bracket 30 can also be positioned and fixed by means of screw locking and positioning post positioning holes.

[0078] In one embodiment, the electronic device includes a host and a wearable device. The host includes the housing 10, the middle frame 40, the circuit board 20, the antenna bracket 30, etc. in any of the above embodiments. The left and right sides of the middle frame 40 are provided with a storage slot 42, and the storage slot 42 is used to store the wearable device. The wearable device can be but is not limited to the earphone 80. The wearable device has a storage state and a removal state. When the wearable device is in the storage state, it is located in the storage slot 42. When the wearable device is in the removal state, it is located outside the storage slot 42 and separated from the host.

[0079] Exemplarily, the electronic device is a learning machine, which includes a host and a pair of headphones 80. A display module 50 is provided on the upper side of the host, and storage slots 42 are provided on the left and right sides of the host. In some learning scenarios, sound is played directly through the host. In some scenarios that require immersive learning, the user can take out two headphones 80 from the left and right sides of the host and wear them.

[0080] It is understandable that, referring to Figures 3 to 8 , Figures 11 to 13 When storage slots 42 for storing earphones 80 are provided on the left and right sides of the middle frame 40, the antenna bracket 30 is vertically arranged on the front and / or rear sides of the middle frame 40, so that the antenna bracket 30 can avoid the space directly above and below the storage slots 42, thereby avoiding or reducing the interference of high-density electronic devices inside the earphones 80 with the antenna 34 signal.

[0081] Optionally, notches of the storage slot 42 are respectively provided on the left and right sides of the middle frame 40, and access ports are provided on the left and right sides of the shell 10. The access ports are connected to the storage slot 42, and the user can put in or take out the wearable device through the access ports.

[0082] In one embodiment, the electronic device includes a display module 50 and a middle frame 40, and the display module 50 and the circuit board 20 are respectively arranged on the upper and lower sides of the middle frame 40. The electronic device also includes a battery 71, the middle frame 40 is provided with a mounting groove, the electronic device is arranged in the mounting groove, and the display module 50 and the circuit board 20 are both electrically connected to the battery 71.

[0083] Optionally, storage slots 42 are provided at the left and right ends of the middle frame 40, and a mounting slot is provided between the two storage slots 42. The notches of the two storage slots 42 are respectively located on the left and right sides of the middle frame 40, and the notches of the mounting slots are located on the side close to the display module 50. When the two earphones 80 are respectively installed in the storage slots 42 on both sides, the battery 71 is located in the middle of the two earphones 80, the display module 50 is located on the upper side of the middle frame 40, and the circuit board 20 is located on the lower side of the middle frame 40. This layout has a compact structure, and the middle frame 40 can be used to install and fix multiple structural parts, which is conducive to reasonable wiring. In addition, the antenna bracket 30 located on the front and rear sides of the middle frame 40 can not only be installed and fixed on the middle frame 40, but also can be kept at a certain distance from the various electronic devices on the middle frame 40 as much as possible, so as to better meet the clearance requirements of the antenna 34.

[0084] In one embodiment, the housing 10 includes a first shell 11 and a second shell 12, which are respectively disposed on the upper and lower sides of the circuit board 20 and connected to each other. The first shell 11 is a top shell, and the second shell 12 is a bottom shell.

[0085] It is understandable that the first housing 11 and the second housing 12 are mounted on the outside of the middle frame 40 by buckling them up and down during installation. Figures 5 to 13 , the middle frame 40 is located on the upper side of the circuit board 20, and the middle frame 40 may block the upper side of the electrical connector 21 (such as Pogopin) of the circuit board 20 for connecting the feed point 341 of the antenna 34. In this way, if the antenna 34 is set on the first shell 11 and / or the second shell 12, when the first shell 11 and the second shell 12 are installed up and down, it is difficult to achieve the connection of the feed point 341 of the antenna 34 on the shell to the electrical connector 21. In the present application, the antenna bracket 30 is on the front side and / or the rear side of the middle frame 40, and the antenna bracket 30 can be installed on the middle frame 40 from front to back or from back to front, and the feed point 341 of the antenna 34 on the inner side of the antenna bracket 30 The extended frame portion 32 can smoothly dock with the electrical connector 21 (such as Pogopin) on the upper side of the circuit board 20.

[0086] In one embodiment, referring to Figures 5 to 8 The electronic device further includes a button 73, which may be, but is not limited to, a power button. When the left and right sides of the electronic device are provided with storage slots 42 for storing earphones 80 or other wearable devices, and the front (upper side) of the electronic device is provided with a display module 50, the button 73 is arranged on the front or rear side of the electronic device, thereby obtaining a better operating effect, being more beautiful, and facilitating wiring.

[0087] Optionally, the middle frame 40 and the front and rear sides of the circuit board 20 are both provided with antenna brackets 30, and the antenna 34 provided on the antenna bracket 30 on the front side is a mobile communication antenna 34, and correspondingly, the button 73 is provided on the front side of the electronic device. The button 73 is electrically connected to the circuit board 20. Compared with electronic components such as the charging interface 74 and the battery 71 wiring, the button 73 has less influence on the signal reception and transmission of the antenna 34. The button 73 with less influence and the main mobile communication antenna 34 are both provided on the front side, which not only meets the layout requirements of the button 73 and the antenna 34, but also minimizes the influence on the main mobile communication antenna 34. Among them, in the process of routing the mobile communication antenna 34, the area overlapping with the routing of the button 73 can be avoided, for example, when the outer surface of the antenna bracket 30 is formed by laser forming the antenna 34 circuit pattern, the area directly facing the front side of the button 73 is avoided.

[0088] Optionally, the first antenna bracket 301 is provided with a first avoidance hole 3011, the housing 10 is provided with a second avoidance hole 101, the first avoidance hole 3011 is aligned with the second avoidance hole 101, the button 73 is passed through the first avoidance hole 3011 and / or the second avoidance hole 101, and the button 73 is electrically connected to the circuit board 20. Among them, the first antenna bracket 301 can not only arrange the antenna 34, but also guide and position the button 73, and has more functions.

[0089] In one embodiment, referring to Figure 5 , Figure 8 , Fig.10 , Fig.11 The electronic device also includes a battery 71, which is used to power electrical devices in the electronic device. For example, the battery 71 is electrically connected to the circuit board 20, the display module 50, etc. The battery 71 is electrically connected to the circuit board 20 through a first electrical connection line 72, and the first electrical connection line 72 is located on the side of the battery 71 and the middle frame 40 close to the second antenna bracket 302.

[0090] The electronic device also includes a charging interface 74, the second antenna bracket 302 is provided with a third avoidance hole 3021, the shell 10 is provided with a fourth avoidance hole 102, the third avoidance hole 3021 is aligned with the fourth avoidance hole 102, the charging interface 74 is passed through the third avoidance hole 3021, and the charging interface 74 is electrically connected to the circuit board 20.

[0091] Placing the first electrical connection line 72 of the battery 71 and the charging interface 74, which are relatively large and have a greater impact on the signal of the antenna 34, on the side close to the second antenna bracket 302 can avoid the need to avoid many areas when routing the mobile communication antenna 34 on the first antenna bracket 301, thereby ensuring the signal of the mobile communication antenna of the first antenna bracket 301, that is, ensuring the model of the main antenna. The antenna 34 (such as a WI FI antenna) on the second antenna bracket 302 has a lower routing area requirement. When routing the antenna 34 on the bracket outer surface 311 of the second antenna bracket 302, it is easy to avoid the charging interface 74 and the first electrical connection line 72 on the rear side and other areas to meet the signal requirements.

[0092] It can be understood that when a first antenna bracket 301 is provided on the front side of the interior of the electronic device housing 10 and a second antenna bracket 302 is provided on the rear side, the button 73 is arranged on the front side and the charging port 74 and the battery 71 are arranged on the rear side, which can ensure that the signals of the front and rear antennas 34 can be better received and transmitted.

[0093] It should be noted that in other embodiments, the middle frame 40 may not be provided.
