The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application.

[0053] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] As users pursue the ultimate performance of electronic devices, the functionality of electronic devices is becoming stronger and stronger. At the same time, the types and quantities of components used to realize various functions are becoming more and more abundant. These high-performance functions are also increasing the demand for the battery capacity of electronic devices. The increase in battery capacity can extend the use time of electronic devices and ensure their performance, thereby improving the user experience. In order to meet the high performance of electronic devices, it also poses a huge challenge to the internal layout space of electronic devices.

[0055] In the related art, the circuit board of the electronic device needs to be stably connected to the frame to ensure reliability during use. The circuit board is usually provided with a connection area for inserting fasteners to connect the circuit board to the frame. However, under this connection method, the area and height of the circuit board are large, occupying a large internal space. Figures 1 to 6 As shown, due to the limitation of the internal space layout of the electronic device, the display screen connector cannot be stacked with the device mainboard, but can only be set at both ends of the battery with the device mainboard. In order to achieve the electrical connection between the display screen connector and the device mainboard, a flexible circuit board needs to be set above the battery. In addition, the device mainboard and various speaker boxes need to be connected to the frame through fasteners, and the speaker box and the device mainboard also need to be connected through fasteners. Under this structure, the flexible circuit board needs to pass through the upper surface of the battery, the number of fasteners is large and protrudes from the surface of the device mainboard. The above factors occupy the height space inside the electronic device, which is not conducive to the layout of the functional components of the electronic device. It also makes it difficult to further increase the height of the battery, which restricts the increase in battery capacity.

[0056] Specifically, if Figures 1 to 6 As shown, in the functional area below the electronic device, a speaker box and a first circuit board are arranged, and three fasteners are used for locking. One fastener locks the first circuit board, one fastener locks the speaker box, and one fastener locks the first circuit board and the speaker box at the same time, that is, at least two fasteners are required to lock the internal parts of the frame. In the functional area above the electronic device, three fasteners are used to simultaneously lock the display connector and the other two display brackets, that is, at least one fastener is required for each display connector to lock its display bracket. That is, the layout space of the current functional area requires at least 4 fasteners to fix the first circuit board, the speaker box and the display connector. The number of fasteners is large, the structure is complex, and the assembly difficulty is high.

[0057] At the same time, due to the limited layout space of the lower functional area, the display connector can only be arranged in the upper functional area. The display circuit board passes through the battery surface and occupies the Z-direction space of the battery. The thickness of the display circuit board is measured in mm. The battery capacity is expected to be lost by 1000mAh for each unit of thickness, and the battery life is expected to be reduced by 2 hours, which affects the further improvement of the battery capacity of the electronic device and makes it impossible to further extend the user's usage time.

[0058] Based on the above reasons, the present application discloses an electronic device, such as Figures 8 to 37 FIG. 1 is a schematic diagram of an electronic device provided in an embodiment of the present application. According to the electronic device provided in an embodiment of the present application, the area of ​​the first circuit board can be reduced and the space above the first circuit board can be freed up for arranging functional components such as display screen connectors, which is beneficial to optimizing the internal layout of the electronic device and ensuring performance improvement.

[0059] The electronic device provided by the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. In the embodiment of the present application, the first direction X is the length direction of the battery device, and the second direction Z intersects with the first direction X. Further, the second direction Z is perpendicular to the first direction X. Specifically, in the embodiment of the present application, the second direction Z can be the thickness direction of the electronic device.

[0060] As shown in the figure, the electronic device disclosed in the present application may specifically include: a frame body 10, a speaker box 60 and a first circuit board 20, wherein a accommodating cavity 103 is arranged in the frame body 10, the speaker box 60 and the first circuit board 20 are arranged side by side in the accommodating cavity 103, a metal connector 30 is arranged on one side edge of the first circuit board 20 close to the speaker box 60, the thickness of the metal connector 30 is less than the thickness of the first circuit board 20, and the speaker box 60 and the first circuit board 20 are fixedly connected by the metal connector 30.

[0061] Specifically, Figure 4 As shown, the accommodating cavity 103 of the frame 10 is divided into a battery area 101 and two functional areas 102. The two functional areas 102 are arranged on both sides of the battery area 101 along the first direction X. The battery is arranged in the battery area 101. The first circuit board 20, the metal connector 30 and the speaker box 60 are arranged in the same one of the two functional areas 102. In the embodiment of the present application, the first circuit board 20 and the speaker box 60 are arranged in the functional area 102 below the battery area 101, so that the electronic device can output sound from below. The upper functional area 102 can be used to set the second circuit board 70 and the camera module, wherein the speaker box 60 is the shell of the speaker module in the electronic device, and the speaker module is arranged inside it. The speaker module is a key component for the electronic device to output sound. The speaker box 60 provides a fixed support function and a stable working environment for the speaker module to protect the speaker module from interference and damage.

[0062] In the embodiment of the present application, the speaker box 60 and the first circuit board 20 are arranged side by side in the accommodating cavity 103 of the frame 10, and the first circuit board 20 is further provided with a metal connector 30 on the side close to the speaker box 60. The speaker box 60 and the first circuit board 20 are fixedly connected by the metal connector 30. In this way, there is no need to separately set a connection area on the first circuit board 20 to penetrate the fastener 33, so that the area of ​​the first circuit board 20 can be reduced, and the top space of the first circuit board 20 along the second direction Z can also be avoided. Furthermore, since the thickness of the metal connector 30 is less than the thickness of the first circuit board 20, the top space of the metal connector 30 is also released, thereby facilitating the layout of various functional components inside the electronic device and ensuring that various functions of the electronic device can be realized.

[0063] Optionally, a first mounting hole 321 is provided on the metal connector 30 , a second mounting hole 621 is provided on the speaker box 60 , and the speaker box 60 and the first circuit board 20 are fixedly connected by fasteners 33 provided in the first mounting hole 321 and the second mounting hole 621 .

[0064] Specifically, the first mounting hole 321 and the second mounting hole 621 are arranged opposite to each other along the second direction Z, so that the fastener 33 can pass through the first mounting hole 321 and the second mounting hole 621 at the same time, and finally be fixedly connected to the frame 10, so as to realize the connection between the speaker box 60 and the first circuit board 20, and the connection between the two and the frame 10 at the same time through the metal connector 30 and the fastener 33. In this way, the speaker box 60 and the first circuit board 20 do not need to be fixed separately, which can save the number and occupied space of the fastener 33. In addition, the metal connector 30 is arranged at the edge of the first circuit board 20, and the first circuit board 20 does not need to be separately provided with a connection area for passing the fastener 33, so that the area of ​​the first circuit board 20 can be reduced, and the fastener 33 can save the height space occupied by the top of the first circuit board 20 in the accommodating cavity 103. In practical applications, the fastener 33 can be a screw, a bolt, a pin, etc.

[0065] Among them, the metal connecting part 30 includes a first connecting part 31 and a second connecting part 32 which are connected to each other. The first connecting part 31 and the first circuit board 20 are stacked and welded along the second direction Z, and the second connecting part 32 extends from the first connecting part 31 toward the speaker box 60 to the outside of the first circuit board 20. The first mounting hole 321 is set on the second connecting part 32. The first mounting hole 321 can be used to penetrate the fastener 33, thereby avoiding opening a hole on the first circuit board 20 for penetrating the fastener 33. Since no hole is needed on the first circuit board 20, it is beneficial to reduce the area of ​​the first circuit board 20 and save space above the first circuit board 20.

[0066] Optionally, the frame 10 is also provided with a fixing portion 11 protruding toward the second connecting portion 32, and a fourth mounting hole 111 is also provided on the fixing portion 11. The first mounting hole 321, the second mounting hole 621 and the fourth mounting hole 111 are relatively arranged along the second direction Z. During assembly, the second connecting portion 32 of the metal connecting piece 30 can be overlapped on top of the fixing portion 11, and the first mounting hole 321 is opposite to the fourth mounting hole 111, and the fastener 33 is then passed through the first mounting hole 321, the second mounting hole 621 and the fourth mounting hole 111 in sequence, and finally the fastener 33 is fixed in the fourth mounting hole 111, thereby realizing the connection between the first circuit board 20, the speaker box 60 and the frame 10.

[0067] It can be understood that, since the second connection portion 32 of the metal connector 30 extends outside the first circuit board 20, and the first mounting hole 321 is provided on the second connection portion 32, accordingly, the fastener 33 used to connect the first circuit board 20 and the frame 10 is also provided outside the first circuit board 20, thereby avoiding the fastener 33 from passing through the first circuit board 20 and occupying the layout space above the first circuit board 20. In addition, since the fixing portion 11 protrudes toward the second connection portion 32, it can support the structure overlapped thereon, which is convenient for supporting the locking operation of the fastener 33, and the depth of the fourth mounting hole 111 can be set larger, thereby increasing the number of locking turns of the fastener 33, improving the locking strength, and ensuring the connection reliability between the first circuit board 20, the speaker box 60 and the frame 10.

[0068] Furthermore, the thickness of the second connection portion 32 is greater than the thickness of the first connection portion 31 and less than the thickness of the first circuit board 20. The second connection portion 32 includes an extension portion 322 and a folded portion 323 connected in a bent manner. The extension portion 322 is connected to the first connection portion 31, and the folded portion 323 is folded back from the extension portion 322 toward the first connection portion 31. The thickness of the second connection portion 32 is the sum of the thickness of the extension portion 322 and the folded portion 323. Figures 12 to 16 As shown, the folded portion 323 and the extending portion 322 are stacked along the second direction Z, and the metal connector 30 may be an integrally formed structure. Specifically, the first connecting portion 31 , the extending portion 322 and the folded portion 323 are an integrally formed structure.

[0069] It should be understood that, since the second connection part 32 is provided with a first mounting hole 321 for inserting the fastener 33, the thickness of the second connection part 32 is set to be greater than the thickness of the first connection part 31, which can enhance the structural strength of the second connection part 32, so that when the second connection part 32 is opened, the risk of damage to the surrounding structure of the first mounting hole 321 can be reduced. At the same time, when the fastener 33 is fastened in the first mounting hole 321, it is beneficial to reduce the risk of crushing of the second connection part 32, ensure the connection effect between the speaker box 60, the first circuit board 20 and the frame 10, and improve the structural stability and reliability of the electronic device. Due to the limited internal space of the electronic device. In addition, the double-layer structure design of the extension part 322 and the bending part of the second connection part 32, the bottom layer structure can be used as the main connecting part between the metal connection part 30 and the frame 10, and the top layer structure can be designed as a limiting convex bump 324, which is used to fix other component structures such as the display bracket 50, thereby improving the application range and versatility of the metal connection part 30.

[0070] In practical applications, the metal connector 30 and the first circuit board 20 can be pre-installed to facilitate subsequent assembly. Specifically, the first connection portion 31 is welded on one side of the first circuit board 20 along the second direction Z, and a solder foot 311 is formed on the other side of the first circuit board 20 along the second direction Z. The first connection portion 31 and the first circuit board 20 are stacked along the second direction Z, and the second connection portion 32 extends to the outside of the first circuit board 20. It should be noted that the second connection portion 32 extends to the outside of the first circuit board 20, which means that along the second direction Z, the orthographic projection of the second connection portion 32 does not coincide with the orthographic projection of the first circuit board 20. In this way, the first circuit board 20 can be fixedly connected to the frame 10 by passing through the second connection portion 32 of the metal connector 30 through the fastener 33, avoiding the fastener 33 from directly passing through the first circuit board 20, that is, the fastener 33 is cancelled above the first circuit board 20, thereby saving space above the first circuit board 20.

[0071] Optionally, the electronic device also includes a display connector 40 and a display bracket 50. The display connector 40 is arranged between the first circuit board 20 and the speaker box 60. The display bracket 50 covers at least a portion of the display connector 40 and is connected to the second connecting portion 32 of the metal connector 30. In this way, the metal connector 30 can not only realize the connection between the speaker box 60, the first circuit board 20 and the frame 10, but also simultaneously realize the fixation of the display bracket 50, which greatly improves the reuse rate of the structure and saves the layout space of the display bracket 50 fixing structure.

[0072] It should be noted that in the prior art, since the fastener 33 occupies the space above the first circuit board 20, the display screen connector 40 cannot be arranged in the same functional area 102 of the frame 10 as the first circuit board 20, but can only be arranged in another functional area 102 of the frame 10. In this way, in order to achieve the electrical connection between the display screen connector 40 and the first circuit board 20, the display screen connection circuit board needs to be arranged above the battery across the battery area 101. In the embodiment of the present application, since the height space above the first circuit board 20 is saved, the space above the first circuit board 20 can be used to arrange the display screen connector 40, so that the first circuit board 20 and the display screen connector 40 can be arranged in the same functional area 102. Since the display screen connector 40 and the first circuit board 20 are both located in the same functional area 102, the flexible circuit board 80 used to connect the two no longer needs to pass through the battery area 101, thereby saving the layout space above the battery, so that the size of the battery in the height direction can be further increased, and the battery capacity is improved.

[0073] In some embodiments, the thickness of the display circuit board 41 is 0.13 mm. Since the battery no longer passes through the display circuit board 41, the battery thickness can be increased by 0.13 mm. When the battery capacity can be increased by 1000 mAh for every 1 mm increase in thickness, the height space saved by the display circuit board 41 can increase the battery capacity by 130 mAh.

[0074] In actual application, the display screen connector 40 is electrically connected to the display screen, and is electrically connected to the first circuit board 20 through the display screen circuit board 41, so as to realize the transmission of current and signals between the display screen and the first circuit board 20. By setting the display screen bracket 50, the display screen connector 40 can be covered. On the one hand, it can play a certain protective role on the display screen connector 40, reduce the contact between the display screen connector 40 and other components inside the electronic device, and ensure the stability of the display screen connector 40. On the other hand, after the display screen bracket 50 covers the upper part of the display screen connector 40, the two ends of the display screen bracket 50 are also connected to the second connecting part 32 of the metal connector 30, so that the display screen connector 40 and the first circuit board 20 can be pressed to a certain extent, ensuring the compactness and flatness of the structure, and at the same time, further expanding the space above the first circuit board 20.

[0075] In some optional embodiments of the present application, the second connection portion 32 is provided with a limiting convex bulge 324, the limiting convex bulge 324 protrudes along the second direction Z toward the side away from the frame 10, and the end of the display bracket 50 is clamped in the limiting convex bulge 324. Among them, the limiting convex bulge 324 is provided with an opening 3241 on the side opposite to the display bracket 50, and the end of the display bracket 50 extends from the opening 3241 to the limiting convex bulge 324, and the display bracket 50 is limited in multiple directions by the limiting convex bulge 324.

[0076] Specifically, the limiting convex 324 and the second connecting portion 32 are an integrally formed structure. In practical applications, the metal connecting member 30 is a metal member, and the limiting convex 324 can be formed by stamping or casting. The height of the limiting convex 324 along the second direction Z can be slightly greater than the height of the end of the display bracket 50, so that the end of the display bracket 50 extends into the limiting convex 324. Further, the limiting convex 324 is provided with an avoidance hole 3242 on one side close to the first mounting hole 321. It can be understood that, as shown in FIG. Fig.15 As shown, due to the setting of the avoidance hole 3242, the fastener 33 can be prevented from being affected by the limiting convex hump 324 when passing through the first mounting hole 321. At the same time, the area of ​​the second connecting part 32 of the metal connecting part 30 can be reduced, which is beneficial to saving the area occupied by the second connecting part 32.

[0077] In practical applications, the metal substrate of the metal connector 30 can be processed to form the limiting convex bump 324, and then the extension portion 322 and the folded portion 323 can be formed by bending the substrate. At this time, the extension portion 322 is coplanar with the first connection portion 31, and then the first connection portion 31 is welded to the first circuit board 20. The first mounting hole 321 of the second connection portion 32 passes through the extension portion 322 and the folded portion 323 along the second direction Z.

[0078] In some other optional embodiments of the present application, a third mounting hole 51 is provided at the end of the display bracket 50, and the third mounting hole 51 is opposite to the first mounting hole 321, the second mounting hole 621 and the fixing portion 11 along the second direction Z. The fastener 33 passes through the third mounting hole 51, the first mounting hole 321, the second mounting hole 621 in sequence and fixes the display bracket 50 to the fourth mounting hole 111 of the fixing portion 11.

[0079] Specifically, the frame 10 is provided with a positioning column 12, the display bracket 50 is provided with a positioning hole, and the display bracket 50 is provided above the metal connector 30. During assembly, the positioning hole of the display bracket 50 can be passed through the positioning column 12 to achieve preliminary positioning, and the third mounting hole 51, the first mounting hole 321, the second mounting hole 621 and the fourth mounting hole 111 on the fixing portion 11 of the frame 10 are arranged in sequence along the second direction Z, and the fastener 33 can pass through the third mounting hole 51, the first mounting hole 321, and the second mounting hole 621 in sequence and be fixedly connected in the third mounting hole 51. Under this structure, the second connecting portion 32 of the metal connector 30 does not need to be provided with a limiting convex bump 324, and the display bracket 50 is connected to the fastener 33 through the third mounting hole 51, and the structure can be simpler.

[0080] It should be noted that, in practical applications, the above two structures of metal connectors 30 can be provided for cooperation, that is, one end of the display screen bracket 50 is limitedly matched with the limiting convex 324 of the metal connector 30, and the other end of the display screen bracket 50 is connected to the frame 10 through the third mounting hole 51 through the fastener 33; or, the structure of the metal connector 30 at both ends of the display screen can be the same, so that both ends of the display screen bracket 50 can be limitedly matched with the limiting convex 324 of the metal connector 30 at the same time, or, both ends of the display screen bracket 50 can be provided with the third mounting hole 51, and the third mounting hole 51 is arranged relative to the first mounting hole 321, the second mounting hole 621 and the fourth mounting hole 111 to achieve connection with the frame 10 through the fastener 33. The technician can make a flexible choice, and this application does not make any specific limitation on this.

[0081] Optionally, the frame 10 is provided with a fixing portion 11 protruding toward the second connecting portion 32 along the second direction Z, wherein a limiting step 112 is provided on the outer peripheral surface of the fixing portion 11, the second connecting portion 32 overlaps the top of the fixing portion 11 and is enclosed with the limiting step 112 to form a limiting groove 113, and the speaker box 60 includes a main body 61 and an insert 62 exposed from the main body 61, and the insert 62 is at least partially overlapped on the limiting step 112 and is located in the limiting groove 113.

[0082] In some embodiments of the present application, the main body 61 of the speaker box 60 includes a housing, the insert 62 is a metal insert 62, and is integrally processed with the housing through an insert 62 injection molding process, the insert 62 is exposed from the housing, and is substantially parallel to the frame 10. The second mounting hole 621 is set on the insert 62.

[0083] During assembly, first overlap the second mounting hole 621 on the limiting step 112 on the fixed part 11 of the frame 10, then overlap the second connecting part 32 of the metal connecting part 30 on the top of the fixed part 11, and finally pass the fastener 33 through the first mounting hole 321 and the second mounting hole 621 in sequence and finally fix it to the fourth mounting hole 111 of the fixed part 11. In this way, the connection between the first circuit board 20, the speaker box 60 and the frame 10 can be achieved through the metal connecting part 30.

[0084] In the above embodiment, the thickness of the first circuit board 20 is 0.5 mm, the thickness of the metal connector 30 is 0.15 mm, the total thickness of the extension portion 322 and the folded portion 323 is 0.3 mm, the thickness of the insert 62 of the speaker box 60 is 0.15 mm, the difference between the second height of the insert 62 and the first height of the limiting step 112 is 0.05 mm, and the end of the display bracket 50 is assembled into the limiting convex bump 324, and does not occupy the height space of the fastener 33. Therefore, the total thickness of the above structure is 0.5 mm, that is, the thickness of the first circuit board 20.

[0085] It should be noted that when the display bracket 50 is provided with a fourth mounting hole 111, the insert 62 of the speaker box 60 can be overlapped on the limiting step 112 of the fixing part 11 first, and then the second connecting part 32 of the metal connecting part 30 can be overlapped on the top of the fixing part 11, and then the display bracket 50 can be overlapped on the top of the metal connecting part 30, and finally the fastener 33 is passed through the third mounting hole 51, the first mounting hole 321, and the second mounting hole 621 in sequence and finally fixed to the fourth mounting hole 111. In this way, the connection between the display bracket 50, the first circuit board 20, the speaker box 60 and the frame 10 can be realized through the metal connecting part 30.

[0086] In the above embodiment, the height layout space of the position of the fastener 33 includes: the thickness of the insert 62 of the speaker box 60 is 0.15 mm, the difference between the second height of the insert 62 and the first height of the limiting step 112 is 0.05 mm, the thickness of the second connecting portion 32 of the metal connecting member 30 is 0.15 mm, the thickness of the display bracket 50 is 0.15 mm, and the total thickness is 0.5 mm, that is, the thickness of the first circuit board 20.

[0087] It should be noted that if Figure 7 As shown, in the prior art, the fastener 33 directly passes through the first circuit board 20 and is connected to the frame 10, wherein the head diameter of the fastener 33 is 2.4 mm, and the head edge of the fastener 33 and the first circuit board 20 have a 0.2 mm avoidance gap 114. Under this structure, the rectangular layout area occupied by one fastener 33 is 7.84 mm2, and the battery capacity can be increased by about 20 mAh for every 1 mm2 of layout area saved. In the embodiment of the present application, the connection between the first circuit board 20 and the speaker box 60 is simultaneously realized by two fasteners 33, thereby saving the layout area of ​​one fastener 33, that is, increasing the battery capacity by about 156.8 mAh.

[0088] In the embodiment of the present application, the limiting step 112 has a first height along the second direction Z, and the insert 62 has a second height along the second direction Z, wherein the first height is greater than the second height, so that there is an avoidance gap 114 between the top surface of the insert 62 overlapping the limiting step 112 and the bottom surface of the metal connector 30, and the existence of the avoidance gap 114 can ensure the connection between the metal connector 30 and the frame 10.

[0089] On the contrary, when the second height of the insert 62 is greater than the first height of the limiting step 112, the top surface of the insert 62 will protrude from the top surface of the fixing portion 11 of the frame 10 along the second direction Z. During assembly, the metal connector 30 will first overlap the top surface of the insert 62 and cannot contact the fixing portion 11, affecting the grounding of the metal connector 30. Therefore, by setting the first height greater than the second height, it is possible to prevent the insert 62 from being too high to affect the contact between the metal connector 30 and the fixing portion 11 of the frame 10, thereby ensuring the grounding reliability and indirectly ensuring the grounding connection between the first circuit board 20 and the frame 10.

[0090] In practical applications, the difference between the first height and the second height can be set at 0.05 mm to ensure the ground connection between the first circuit board 20 and the frame 10 .

[0091] In another embodiment of the present application, Figure 29 to Figure 31As shown, the metal connector 30 includes two first connecting parts 31 and a second connecting part 32, and the two first connecting parts 31 are respectively located at the two ends of the second connecting part 32. Among them, the two first connecting parts 31 are located on the same side of the second connecting part 32, and the two first connecting parts 31 are both connected to the first circuit board 20, and the second connecting part 32 covers the display connector 40. In this way, the display connector 40 can be directly pressed by the second connecting part 32, so that the display bracket 50 structure can be eliminated, and the internal structure of the electronic device can be further simplified.

[0092] Specifically, the metal connector 30 is formed into a long strip structure. When the two ends of the second connecting parts 32 of the two metal connectors 30 are respectively connected to the frame 10, the middle part of the metal connector 30 can realize pre-compression of the display connector 40. In this way, there is no need to set a display bracket 50 above the display connector 40, thereby saving a display bracket 50 and making the internal structure of the electronic device simpler.

[0093] It should be noted that in the above structure, since the display bracket 50 structure is cancelled, there is no need to set a limiting convex bump 324 on the second connecting portion 32 of the metal connecting member 30. The metal connecting member 30 is directly penetrated by the fastener 33 through the first mounting hole 321 and finally fixedly connected to the frame 10.

[0094] Among them, in the above embodiment, since the display screen bracket 50 is cancelled, the height layout space of the fastener 33 position includes: the thickness of the insert 62 of the speaker box 60 is 0.15 mm, the difference between the second height of the insert 62 and the first height of the limiting step 112 is 0.05 mm, the thickness of the second connecting part 32 of the metal connecting part 30 is 0.15 mm, and the total thickness is 0.35 mm. Compared with setting the display screen bracket 50, 0.15 mm of layout space in the second direction Z is saved.

[0095] In an embodiment of the present application, the electronic device also includes a battery and a second circuit board 70, the first circuit board 20 and the second circuit board 70 are respectively arranged on both sides of the battery, the speaker box 60 and the first circuit board 20 are located on the same side of the battery, and the first circuit board 20 and the second circuit board 70 are electrically connected through a flexible circuit board 80.

[0096] Specifically, the battery is arranged in the battery area 101, the first circuit board 20 is arranged in one of the functional areas 102, the second circuit board 70 is arranged in another functional area 102, and the first circuit board 20 and the second circuit board 70 are electrically connected through the flexible circuit board 80; Fig. 22 As shown, the frame 10 is provided with a mounting groove 13 in the battery area 101 , and the connecting circuit board is at least partially disposed in the mounting groove 13 .

[0097] It should be noted that according to the assembly sequence of the electronic device, the display screen is the last step of the assembly, and the display screen circuit board 41 must be connected to the first circuit board 20 before the display screen is assembled. Therefore, in the assembly sequence, the battery needs to be assembled before the display screen circuit board 41, and the display screen circuit board 41 cannot be arranged under the battery. There is no special requirement for the assembly sequence of the connecting circuit board, so it can be installed using the size of the second direction Z of the frame 10. Specifically, the frame 10 can be made into a mounting groove 13 by removing glue, and the connecting circuit board can be arranged in the mounting groove 13. In this way, the connecting circuit board is located below the battery, and the height space occupied in the second direction Z of the battery area 101 is reduced, thereby saving the height space of the battery area 101, so that the height of the battery can be further increased, and the battery capacity can also be further improved. In practical applications, the size of the mounting groove 13 in the second direction Z can be determined comprehensively based on the thickness of the connecting circuit board and the thickness of the frame 10. When the connecting circuit board is partially arranged in the mounting groove 13 along the second direction Z, the occupation of the height space of the battery area 101 can be reduced. When the connecting circuit board is completely arranged in the mounting groove 13 along the second direction Z, the occupation of the height space of the battery area 101 can be completely avoided.

[0098] The following is an explanation of the assembly sequence of the electronic device in the embodiment of the present application.

[0099] In one embodiment of the present application, the display connector 40 is pre-pressed by the display bracket 50. In this structure, the metal connector 30 is only used to realize the connection between the first circuit board 20, the speaker box 60 and the frame 10. At this time, the speaker box 60 is first assembled to the frame 10, and then the first circuit board 20 is assembled to the frame 10, and the metal connector 30 connected to the first circuit board 20 is pressed on the insert 62 of the speaker box 60, and then the circuit board of the display connector 40 is snapped onto the first circuit board 20, and the display bracket 50 is assembled in place. In the above steps, it is necessary to ensure that the mounting holes of each component are opposite along the second direction Z, and finally the fastener 33 is passed through the mounting holes of each component in turn and locked in the third mounting hole 51 on the fixed part 11 of the frame 10 to complete the assembly process.

[0100] In another embodiment of the present application, the electronic device eliminates the display bracket 50, and the display connector 40 is directly pre-pressed by the metal connector 30. In this structure, the metal connector 30 is not only used to realize the connection between the first circuit board 20, the speaker box 60 and the frame 10, but also plays a pressing role on the display connector 40. At this time, the display connector 40 needs to be assembled before the first circuit board 20, as follows: first, the speaker box 60 is assembled to the frame 10, and then the display connector 40 is assembled to the frame 10, and then the circuit board of the display connector 40 is snapped onto the display connector 40, and finally the first circuit board 20 is assembled to the frame 10, and the display connector 40 is pre-pressed, and finally the fastener 33 is passed through the mounting holes of each component in turn and locked to the third mounting hole 51 on the fixed part 11 of the frame 10 to complete the assembly process.

[0101] In summary, the electronic device provided by the embodiments of the present application has at least the following advantages:

[0102] In the embodiment of the present application, the metal connector includes a first connecting portion and a second connecting portion connected to each other, the first connecting portion is connected to the first circuit board, and the second connecting portion extends outside the first circuit board, wherein the second connecting portion extending outside the first circuit board can be used to pass through a fastener and connect the metal connector to the frame through the fastener. At the same time, since the first connecting portion of the metal connector is connected to the first circuit board, the connection between the first circuit board and the frame is realized, avoiding the direct connection between the first circuit board and the frame through the fastener, thereby saving the height space above the first circuit board. In this way, the space above the first circuit board can be used to set the display screen connector. Since the display screen connector and the first circuit board are located in the same functional area at the same time, the flexible circuit board used to connect the two no longer needs to pass through the battery area, thereby saving the layout space above the battery, so that the size of the battery in the height direction can be further increased, and the battery capacity is improved.
