Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to an electronic device and a method for assembling the electronic device. Background Technology

[0002] Currently, mobile phones and other electronic devices are widely used in people's daily lives and work, becoming indispensable everyday items. With the development of electronic device technology, users have increasingly higher demands for thinner and lighter electronic devices. In existing electronic devices, components such as speakers and circuit boards require considerable installation space, resulting in a relatively large overall thickness, which is detrimental to the design of thinner and lighter electronic devices. Summary of the Invention

[0003] This application provides an electronic device and an assembly method for the electronic device, which helps to reduce the overall thickness of the electronic device and promotes the lightweight and thin design of the electronic device.

[0004] In a first aspect, this application provides an electronic device. The electronic device includes a housing, a first circuit board, and a first speaker. The housing includes a frame and a middle plate. The frame is disposed around the middle plate and fixedly connected to the middle plate. Along the thickness direction of the middle plate, the first circuit board is mounted on one side of the middle plate, and the first speaker is mounted on the other side of the middle plate and electrically connected to the first circuit board.

[0005] The electronic device provided in this application, by mounting the first circuit board and the first speaker on opposite sides of the thickness direction of the middle plate, allows for a larger installation space on the side of the middle plate away from the first circuit board. This increases the effective cavity space for mounting the electronic device's components within the housing, enabling full utilization of the overall space of the electronic device to accommodate more components. This, in turn, helps promote a thinner and lighter design of the electronic device and improves the user experience. Furthermore, when it is necessary to replace or repair the components located on the side of the middle plate away from the first circuit board, it is not necessary to disassemble the first circuit board and the display screen of the electronic device. This simplifies the replacement or repair process of the electronic device's components and avoids damage to the first circuit board and the display screen during disassembly, thereby helping to extend the service life of the electronic device.

[0006] In one possible implementation, the electronic device further includes a cover plate and a first sealant. Along the thickness direction of the middle plate, the cover plate is located on one side of the middle plate and covers the first speaker. The first sealant connects the cover plate and the middle plate. The middle plate, the first speaker, the cover plate, and the first sealant together form the rear acoustic cavity of the first speaker. In this configuration, a complete cavity is formed inside the electronic device to serve as the rear acoustic cavity of the first speaker. Since the first speaker and the first circuit board are respectively mounted on opposite sides of the thickness direction of the middle plate, the first circuit board does not occupy the cavity space of the rear acoustic cavity of the first speaker, thereby increasing the effective cavity space of the rear acoustic cavity of the first speaker, thus enhancing the sound quality of the first speaker and improving the user's audio experience.

[0007] In one possible implementation, the electronic device further includes a battery. Along the thickness direction of the middle plate, the battery and the first speaker are mounted on the same side of the middle plate and spaced apart from the rear acoustic cavity of the first speaker. The cover can be a battery cover or a display screen. With this configuration, the battery and the rear acoustic cavity of the first speaker are completely isolated. On the one hand, when the portion of the cover opposite the battery is pressed by an external force, the air change between the cover and the battery caused by the external force will not be transmitted to the rear acoustic cavity of the first speaker, preventing vibration of the first speaker's diaphragm and avoiding abnormal noises from the electronic device, thus improving the user experience. On the other hand, the vibration generated when the first speaker is operating will not affect the portion of the cover opposite the battery, thereby preventing vibration of the cover caused by the first speaker operating from affecting the battery.

[0008] In one possible implementation, the middle plate has a first through hole that penetrates the middle plate along its thickness direction; the first circuit board has a second through hole that penetrates the first circuit board along its thickness direction and communicates with the first through hole; the electronic device further includes a first connector, a second connector, a bracket, and filler adhesive, the first connector being connected between the middle plate and the first circuit board, the first connector having a third through hole that penetrates the first connector along its thickness direction and communicates with both the first and second through holes, the bracket and the first... Both connectors are located on the side of the first circuit board away from the middle plate. The second connector is connected between the first circuit board and the bracket. The second connector has a fourth through hole, which penetrates the second connector along its thickness direction and communicates with it. The bracket has a fifth through hole, which penetrates the bracket along its thickness direction and communicates with it. The filler fills the first through hole, the second through hole, the third through hole, the fourth through hole, and the fifth through hole. The first sealant covers the filler and is connected between the middle plate and the cover plate.

[0009] In this embodiment, there are two first through holes, spaced apart along the width of the electronic device; there are two second through holes, spaced apart along the width of the electronic device, each second through hole communicating with one first through hole; there are two third through holes, spaced apart along the width of the electronic device, each third through hole communicating with one first through hole and one second through hole; there are two fourth through holes, spaced apart along the width of the electronic device, each fourth through hole communicating with one second through hole; there are two fifth through holes, spaced apart along the width of the electronic device, each fifth through hole communicating with one fourth through hole; there are two filler adhesives, each filler adhesive filling one first through hole, one second through hole, one third through hole, one fourth through hole, and one fifth through hole; the first sealant covers the two filler adhesives.

[0010] In this configuration, each second through hole of the first connector, each third through hole of the first circuit board, each fourth through hole of the second connector, each fifth through hole of the bracket, and each first through hole of the middle plate are interconnected to form a dispensing hole. Production personnel only need to fill each dispensing hole with filler adhesive during dispensing, making the operation very simple. At the same time, this configuration also facilitates production personnel in controlling the amount of filler adhesive used, preventing filler adhesive from overflowing into the dispensing hole, and effectively solving the problem of adhesive overflow during dispensing of electronic devices.

[0011] In one possible implementation, the middle plate is further provided with a clearance hole, which penetrates the middle plate along its thickness direction, is spaced apart from the first speaker, and exposes a portion of the first circuit board. The electronic device also includes a functional device, which passes through the clearance hole and is mounted on the side of the first circuit board facing the middle plate, and is electrically connected to the first circuit board. It is understood that by mounting the functional device on the side of the first circuit board facing the middle plate, on the one hand, the mounting space for the functional device can be reused with the mounting space for components such as the first circuit board and the first speaker, which also helps to reduce the thickness of the electronic device, promoting a thinner and lighter design and improving the user experience. On the other hand, the functional device can be replaced or repaired without disassembling the first circuit board and the display screen of the electronic device, simplifying the replacement or repair operation and preventing damage to the first circuit board and the display screen during disassembly, thereby helping to extend the service life of the electronic device.

[0012] In one possible implementation, the middle plate is further provided with a first mounting groove, the opening of which is located on the surface of the middle plate opposite to the first speaker; the first circuit board is mounted in the first mounting groove. It is understood that by mounting the first circuit board in the first mounting groove, the first circuit board can be located inside the housing, avoiding the first circuit board protruding relative to the housing, fully utilizing the mounting space inside the housing, thereby helping to reduce the thickness of the electronic device and thus promoting a thinner and lighter design for the electronic device.

[0013] In one possible implementation, the middle plate is further provided with a second mounting groove. The opening of the second mounting groove is located on the surface of the middle plate opposite to the first circuit board. Along the length of the electronic device, the second mounting groove is spaced apart from the rear acoustic cavity of the first speaker. The battery is mounted in the second mounting groove. In this configuration, the battery is located outside the rear acoustic cavity of the first speaker. When the area where the battery is located is pressed, the air inside the battery is compressed and transmitted to the rear acoustic cavity of the first speaker, thereby preventing the diaphragm of the first speaker from vibrating. This helps to avoid abnormal noises from the electronic device and improves the user experience.

[0014] In one possible implementation, the electronic device further includes a second circuit board and a first connecting circuit board. Along the thickness direction of the middle plate, the second circuit board and the first connecting circuit board are both mounted on the same side of the middle plate and are spaced apart from the rear acoustic cavity of the first speaker. The first connecting circuit board is located on the side of the battery away from the middle plate and is electrically connected between the first circuit board and the second circuit board, so that the first circuit board and the second circuit board are electrically connected, thereby ensuring that the electronic device can be used normally.

[0015] In one possible implementation, the electronic device includes a first main body, a second main body, and a hinge mechanism. The hinge mechanism connects the first main body and the second main body, and the first and second main bodies are rotatable relative to the hinge mechanism. The first main body includes the frame, the first circuit board, and the first speaker. In this embodiment, the electronic device is a foldable electronic device, which can meet the user's usage needs in different scenarios and further enhance the user experience.

[0016] In one possible implementation, the electronic device further includes a display screen, which is located on the side of the first circuit board opposite to the middle plate along the thickness direction of the middle plate and covers the first circuit board. With this configuration, when it is necessary to replace or repair components other than the first circuit board, it is not necessary to disassemble the display screen. This simplifies the replacement or repair of components in the electronic device and avoids damage to the display screen during disassembly, thereby helping to extend the service life of the electronic device.

[0017] Secondly, this application also provides a method for assembling an electronic device, comprising: providing a housing, a first circuit board, and a first speaker, wherein the housing includes a frame and a middle plate, the frame is disposed around the middle plate and fixedly connected to the middle plate; mounting the first circuit board on one side of the middle plate in the thickness direction; mounting the first speaker on the other side of the middle plate in the thickness direction, and electrically connecting the first speaker to the first circuit board.

[0018] The assembly method for the electronic device provided in this application, by mounting the first circuit board on one side of the thickness direction of the middle plate and mounting the first speaker on the other side of the thickness direction of the middle plate, allows for a larger installation space on the side of the middle plate away from the first circuit board. This increases the effective cavity space for mounting the electronic device's components within the housing, thereby making full use of the overall space of the electronic device to install more components. This contributes to the thinner and lighter design of the electronic device and improves the user experience. On the other hand, when it is necessary to replace or repair the components located on the side of the middle plate away from the first circuit board, it is not necessary to disassemble the first circuit board and the display screen of the electronic device. This simplifies the replacement or repair process of the electronic device's components and avoids damage to the first circuit board and the display screen during disassembly, thus helping to extend the service life of the electronic device.

[0031] Figure 12 This is a flowchart illustrating an assembly method for an electronic device provided in this application. Detailed Implementation

[0032] The embodiments of this application are described below with reference to the accompanying drawings.

[0033] Please refer to the following: Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic diagram of the structure of an electronic device 1000 provided in an embodiment of this application. Figure 2 yes Figure 1 The schematic diagram of the electronic device 1000 shown is viewed from another angle. Figure 3 yes Figure 1 The diagram shows the electronic device 1000 in a folded state. Figure 3 The display screen 100 is not shown in the image.

[0034] This application provides an electronic device 1000, which may be, but is not limited to, a mobile phone, a tablet computer, and a personal computer (PC). The mobile phone may be a candybar phone or a foldable phone with a foldable screen (including inward-folding and outward-folding screens). The following description uses a mobile phone with an inward-folding screen as an example. For ease of description, the width direction of the electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular.

[0035] In this embodiment, the electronic device 1000 includes a display screen 100 and a foldable device 200. The display screen 100 is mounted on one side of the foldable device 200 in the thickness direction. The display screen 100 is used to display text, images, and videos, etc. Exemplarily, the display screen 100 is a foldable display screen 100. Specifically, the display screen 100 includes a first portion 110, a second portion 120, and a foldable portion 130, which is located between the first portion 110 and the second portion 120. The foldable portion 130 can be bent along the X-axis direction. In this embodiment, the display screen 100 is a flexible display screen. For example, the display screen 100 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro-organic light-emitting diode (MOLED) display screen, a micro organic light-emitting diode (MOLED) display screen 100, or a quantum dot light-emitting diode (QLED) display screen, etc.

[0036] The foldable device 200 includes a first body 210, a second body 220, and a pivot mechanism 230, which connects the first body 210 and the second body 220. The first body 210 and the second body 220 are rotatable relative to the pivot mechanism 230, allowing the electronic device 1000 to switch between a folded state and a flattened state. Specifically, the first body 210 carries the first portion 110 of the display screen 100, and the second body 220 carries the second portion 120 of the display screen 100. In other words, the first portion 110 of the display screen 100 is mounted on the first body 210, and the second portion 120 of the display screen 100 is mounted on the second body 220. The pivot mechanism 230 is disposed opposite to the foldable portion 130 of the display screen 100.

[0037] Please refer to the following: Figure 1 and Figure 3 When electronic device 1000 is in the unfolded state, such as Figure 1 As shown, the foldable portion 130 of the display screen 100 unfolds, and the first portion 110 and the second portion 120 unfold relative to each other. At this time, the display screen 100 has a large display area, realizing a large-screen display for the electronic device 1000 and improving the user experience.

[0038] When the first main body 210 and the second main body 220 rotate relative to each other via the rotating shaft mechanism 230, and the first main body 210 and the second main body 220 approach each other, the display screen 100 folds under the action of the first main body 210 and the second main body 220, thereby switching the electronic device 1000 from an unfolded state to a folded state. When the electronic device 1000 is in the folded state, such as Figure 3 As shown, the foldable portion 130 of the display screen 100 is bent, and the first portion 110 and the second portion 120 of the display screen 100 are positioned opposite each other. At this time, the display screen 100 is located between the first main body 210 and the second main body 220, which can greatly reduce the probability of the display screen 100 being damaged and achieve effective protection for the display screen 100.

[0039] In this embodiment, the first body 210 and the second body 220 can have the same or similar structures, or they can have symmetrical or partially symmetrical structures, or they can have completely different structures. The design of the first body 210 will be used as an example for detailed explanation later. In this embodiment, both the first body 210 and the second body 220 can adopt the structure of the first body 210 described later. The basic structure of each component in the second body 220, the connection relationships between components, and the connection relationships between components and other components in the electronic device 1000 can all refer to the relevant design of the first body 210 described later. The second body 220 and the first body 210 can be the same or different in the detailed structure or positional arrangement of their components.

[0040] Please see Figure 4 , Figure 5 and Figure 6 , Figure 4 yes Figure 1 A partial structural diagram of the first main body 210 and the display screen 100 in the electronic device 1000 shown. Figure 5 yes Figure 4 The diagram shows a partial exploded view of the first main body 210 and the display screen 100. Figure 6 It is along Figure 4 The diagram shows the cross-sectional structure after cutting at point AA. "Cut along point AA" means cutting along the plane containing line AA; similar descriptions in the following text can be understood in the same way.

[0041] In this embodiment, the first main body 210 includes a housing 201, a first circuit board 202, a second circuit board 203, a first connector 204, a second connector 205, a bracket 206, a first speaker 207, a second speaker 208, a battery 209, a first connecting circuit board 211, a second connecting circuit board 212, a third connecting circuit board 213, a first sealant 214, a second sealant 216, and a cover plate 215.

Along the thickness direction of the first main body 210 (the Z-axis direction in the figure), the first connector 204 and the second connector 205 are respectively located on opposite sides of the first circuit board 202. Along the thickness direction of the first body 210 (Z-axis direction in the figure), the bracket 206 is located on the side of the second connector 205 away from the first circuit board 202.

The first speaker 207, the battery 209, the second speaker 208, the first connecting circuit board 211, the second connecting circuit board 212, and the third connecting circuit board 213 are all installed on the inside of the housing 201. The first sealant 214 is bonded between the housing 201 and the cover plate 215 to securely connect the cover plate 215 to the housing 201.

[0043] Please refer to the following: Figure 7 , Figure 8 and Figure 9 , Figure 7 yes Figure 5 The diagram shows the structure of the shell 201 in the first main body 210. Figure 8 yes Figure 7 The diagram shows the structure of the housing 201 at another angle. Figure 9 yes Figure 7 The diagram shows a cross-sectional view of the shell 201 after it is cut along BB.

[0044] In this embodiment, the housing 201 includes a frame 10 and a middle plate 20. The frame 10 surrounds the middle plate 20 and is fixedly connected to the middle plate 20. The middle plate 20 includes a first surface 11 and a second surface 12, which are arranged opposite to each other along the thickness direction of the middle plate 20 (Z-axis direction in the figure). The first surface 11 is the side of the middle plate 20 facing the first portion 110 of the display screen 100, and the second surface 12 is the side of the middle plate 20 away from the first portion 110 of the display screen 100.

[0045] The middle plate 20 also includes a clearance hole 101, a first mounting groove 102, a second mounting groove 103, a third mounting groove 104, a fourth mounting groove 105, a mating hole 106, and a first through hole 21. The opening of the first mounting groove 102 is located on the surface of the middle plate 20 opposite to the first speaker 207. That is, the opening of the first mounting groove 102 is located on the first surface 11. The first mounting groove 102 is recessed from the first surface 11 towards the second surface 12. The first mounting groove 102 is used to mount the first circuit board 202, the first connector 204, the second connector 205, and the bracket 206.

[0046] Specifically, the first mounting groove 102 includes two first groove sidewalls 1021, a second groove sidewall 1022, a third groove sidewall 1023, and a groove bottom wall 1024. The two first groove sidewalls 1021, the second groove sidewall 1022, and the third groove sidewall 1023 are arranged around the groove bottom wall 1024 and are all fixedly connected to the groove bottom wall 1024. Along the width direction of the housing 201 (the X-axis direction in the figure), the two first groove sidewalls 1021 are spaced apart and opposite to each other. The second groove sidewall 1022 and the third groove sidewall 1023 are both fixedly connected between the two first groove sidewalls 1021. Along the length direction of the housing 201 (the Y-axis direction in the figure), the second groove sidewall 1022 and the third groove sidewall 1023 are spaced apart and opposite to each other.

[0047] Furthermore, the bottom wall 1024 of the groove also includes a first wall 1024a and a second wall 1024b. The first wall 1024a is fixedly connected between the two first groove side walls 1021 and is spaced apart from both the second groove side wall 1022 and the third groove side wall 1023. The second wall 1024b is fixedly connected between the first wall 1024a and the second groove side wall 1022. For example, there are multiple second walls 1024b. Along the length direction of the housing 201 (the Y-axis direction in the figure), two second walls 1024b are spaced apart.

[0048] Both the clearance hole 101 and the mating hole 106 penetrate the middle plate 20 along its thickness direction and are spaced apart from each other. Specifically, both the clearance hole 101 and the mating hole 106 are located in the bottom wall 1024 of the first mounting groove 102 and penetrate the bottom wall 1024 along its thickness direction, and are spaced apart from each other. In this embodiment, there can be multiple clearance holes 101. Multiple clearance holes 101 are spaced apart from each other. In one possible embodiment, the clearance hole 101 can also be formed by the enclosure of the first wall 1024a of the bottom wall 1024, a first side wall 1021, a second side wall 1022, and a second wall 1024b of the bottom wall 1024. The mating hole 106 can also be formed by the enclosure of the first wall 1024a of the bottom wall 1024, two first side walls 1021, and a third side wall 1023.

[0049] In this embodiment, the openings of the second mounting groove 103, the third mounting groove 104, and the fourth mounting groove 105 are all located on the surface of the middle plate 20 away from the first circuit board 202. That is, the openings of the second mounting groove 103, the third mounting groove 104, and the fourth mounting groove 105 are all located on the second surface 12. The second mounting groove 103, the third mounting groove 104, and the fourth mounting groove 105 are all recessed from the second surface 12 toward the first surface 11 and are spaced apart from each other, and are all spaced apart from the first mounting groove 102. Along the length direction of the housing 201 (the Y-axis direction in the figure), the second mounting groove 103 is located in the middle of the middle plate 20, and the third mounting groove 104 and the fourth mounting groove 105 are respectively located on opposite sides of the second mounting groove 103. In this embodiment, the second mounting groove 103 is used to install the battery 209. The third mounting groove 104 is used to install the second speaker 208 and the second circuit board 203. The fourth mounting groove 105 is used to install the first speaker 207.

[0050] The first through hole 21 penetrates the middle plate 20 along its thickness direction and is spaced apart from the first mounting groove 102, the clearance hole 101, and the mating hole 106. Specifically, the first through hole 21 is located on the bottom wall 1024 of the first mounting groove 102. In this embodiment, there are two first through holes 21. The two first through holes 21 are spaced apart along the width direction of the middle plate 20 (X-axis direction in the figure).

[0051] In addition, the housing 201 is also provided with a first sound outlet 107 and a second sound outlet 108. The first sound outlet 107 and the second sound outlet 108 are respectively located on opposite sides of the housing 201 along its length. The first sound outlet 107 penetrates the sidewall of the frame 10 and the fourth mounting groove 105 along the length of the housing 201 to communicate with the fourth mounting groove 105, thereby connecting the front acoustic cavity of the first speaker 207 to the external environment, and thus enabling the first speaker 207 to emit sound. The second sound outlet 108 penetrates the sidewall of the frame 10 and the third mounting groove 104 along the length of the housing 201 to communicate with the third mounting groove 104, thereby connecting the front acoustic cavity of the second speaker 208 to the external environment, and thus enabling the second speaker 208 to emit sound.

[0052] Please refer to the following: Figure 6 and Figure 10 , Figure 10 yes Figure 5 The diagram shows the structure of the first circuit board 202, the first connector 204, the second connector 205, and the bracket 206 in the electronic device 1000 shown.

[0053] Along the thickness direction of the middle plate 20, the first connector 204, the first circuit board 202, the second connector 205, the bracket 206, the second sealant 216, and the first part 110 of the display screen 100 are all mounted on one side of the middle plate 20. That is, the first connector 204, the first circuit board 202, the second connector 205, the bracket 206, the second sealant 216, and the first part 110 of the display screen 100 are all mounted on the same side of the middle plate 20.

[0054] Specifically, the first circuit board 202, the first connector 204, the second connector 205, the bracket 206, and the second sealant 216 are all located within the first mounting groove 102. A portion of the first circuit board 202 is exposed relative to the clearance hole 101 and the mating hole 106 to facilitate subsequent electrical connection with components such as the battery 209 and the second circuit board 203. For example, the first circuit board 202 is a printed circuit board (PCB). The first circuit board 202 has a second through hole 2021. The second through hole 2021 penetrates the first circuit board 202 along its thickness direction and communicates with the first through hole 21 of the middle plate 20. In this embodiment, there are two second through holes 2021. The two second through holes 2021 are spaced apart along the length direction of the first circuit board 202 (X-axis direction in the figure). Each second through hole 2021 communicates with one first through hole 21 of the middle plate 20.

[0055] The first connector 204 is connected between the middle plate 20 and the first circuit board 202. Specifically, the first connector 204 is connected between the bottom wall 1024 of the first mounting groove 102 and the first circuit board 202. For example, the first connector 204 can be foam. The first connector 204 is provided with a third through hole 2041. The third through holes 2041 penetrate the first connector 204 along the thickness direction of the first connector 204 and communicate with the first through hole 21 and the second through hole 2021. In this embodiment, there are two third through holes 2041. The two third through holes 2041 are spaced apart along the length direction of the first connector 204 (X-axis direction in the figure). Each third through hole 2041 communicates with one first through hole 21 and one second through hole 2021.

[0056] Along the thickness direction of the electronic device 1000, both the second connector 205 and the bracket 206 are mounted on the side of the first circuit board 202 opposite to the middle plate 20. The second connector 205 connects the bracket 206 and the first circuit board 202. For example, the second connector 205 can be foam. The second connector 205 has a fourth through hole 2051. The fourth through hole 2051 penetrates the second connector 205 along its thickness direction and communicates with a second through hole 2021. In this embodiment, there are two fourth through holes 2051. The two fourth through holes 2051 are spaced apart along the length direction of the second connector 205 (X-axis direction in the figure). Each fourth through hole 2051 communicates with a second through hole 2021 of the first circuit board 202.

[0057] The bracket 206 is provided with a fifth through hole 2061. The fifth through hole 2061 penetrates the bracket 206 along its thickness direction and communicates with the fourth through hole 2051 of the second connector 205. In this embodiment, there are two fifth through holes 2061. The two fifth through holes 2061 are spaced apart along the length direction of the bracket 206 (X-axis direction in the figure). Each fifth through hole 2061 communicates with a fourth through hole 2051.

[0058] It is understood that the first circuit board 202 can be fixedly connected to the middle plate 20 and the bracket 206 through the first connector 204 and the second connector 205, and the first connector 204 and the second connector 205 can form a seal between the first circuit board 202 and the middle plate 20, and between the first circuit board 202 and the bracket 206. At the same time, the first connector 204 and the second connector 205 have good elasticity and cushioning performance, which can absorb and disperse external impact forces, thereby reducing damage to the first circuit board 202 caused by the electronic device 1000 during drops or vibrations, and also reducing noise generation.

[0059] In this embodiment, after the first connector 204, the first circuit board 202, the second connector 205, and the bracket 206 are all installed onto the middle plate 20 of the housing 201, each second through hole 2021 of the first connector 204, each third through hole 2041 of the first circuit board 202, each fourth through hole 2051 of the second connector 205, each fifth through hole 2061 of the bracket 206, and each first through hole 21 of the middle plate 20 are connected to form a dispensing hole 210a. That is, the first body 210 of the electronic device 1000 is provided with two dispensing holes 210a. The two dispensing holes 210a are spaced apart along the width direction of the first body 210 (X-axis direction in the figure).

[0060] Please continue reading. Figure 6 Along the thickness direction of the middle plate 20, the second sealant 216 is installed on the side of the middle plate 20 away from the first speaker 207 and covers the fifth through hole 2061 of the bracket 206. Along the thickness direction of the middle plate 20, the display screen 100 is located on the side of the first circuit board 202 away from the middle plate 20 and covers the first circuit board 202. Specifically, the display screen 100 is installed on the side of the second sealant 216 away from the middle plate 20. At this time, the bracket 206 is located between the first part 110 of the display screen 100 and the second connector 205. It can be understood that the second connector 205 is relatively flexible, while the bracket 206 has a certain degree of rigidity. By setting the bracket 206 between the second connector 205 and the display screen 100, the bracket 206 can provide rigid support for the display screen 100 to prevent the display screen 100 from denting when pressed, thus ensuring better reliability of the display screen 100.

[0061] In addition, the electronic device 1000 also includes a filler adhesive (not shown in the figure), which fills the first through hole 21, the second through hole 2021, the third through hole 2041, the fourth through hole 2051, and the fifth through hole 2061. That is, the filler adhesive fills the dispensing hole 210a. In this embodiment, there are two filler adhesives. Each filler adhesive fills one first through hole 21, one second through hole 2021, one third through hole 2041, one fourth through hole 2051, and one fifth through hole 2061. That is, each filler adhesive fills one dispensing hole 210a. With this setting, when the production personnel perform dispensing, they only need to fill the filler adhesive into the dispensing hole 210a, which is very convenient. At the same time, it can also control the amount of filler adhesive used, avoiding the filler adhesive overflowing from the dispensing hole 210a, which can effectively solve the problem of adhesive overflow that occurs when the electronic device 1000 is dispensing.

[0062] Please refer to the following: Figure 6 and Figure 11 , Figure 11 yes Figure 4 A partial structural schematic diagram of the first main body 210 shown.

[0063] Along the thickness direction of the middle plate 20, the battery 209, the first speaker 207, the second circuit board 203, the second speaker 208, the first connecting circuit board 211, the second connecting circuit board 212, the third connecting circuit board 213, the first sealant 214, and the cover plate 215 are all installed on the other side of the middle plate 20. That is, the battery 209, the first speaker 207, the second circuit board 203, the second speaker 208, the first connecting circuit board 211, the second connecting circuit board 212, the third connecting circuit board 213, the first sealant 214, and the cover plate 215 are all installed on the same side of the middle plate 20.

[0064] Specifically, battery 209 is mounted in the second mounting slot 103. First speaker 207 is mounted in the fourth mounting slot 105. Second speaker 208 and second circuit board 203 are both mounted in the third mounting slot 104. Along the width direction of electronic device 1000 (X-axis direction in the diagram), the second speaker 208 and second circuit board 203 are arranged side-by-side. The second circuit board 203 is a printed circuit board (PCB).

[0065] In this embodiment, the first connecting circuit board 211, the second connecting circuit board 212, and the third connecting circuit board 213 are all located on the side of the battery 209 opposite to the middle plate 20. Exemplarily, the first connecting circuit board 211, the second connecting circuit board 212, and the third connecting circuit board 213 are all flexible printed circuit boards (FPCs). Specifically, the first connecting circuit board 211 is electrically connected between the first circuit board 202 and the second circuit board 203, enabling electrical conductivity between the two circuit boards. The second connecting circuit board 212 is electrically connected between the first circuit board 202 and the battery 209, enabling electrical conductivity between the two circuit boards. The third connecting circuit board 213 is electrically connected between the first circuit board 202 and the fourth circuit board 221 of the second main body 220, enabling electrical conductivity between the first main body 210 and the second main body 220.

[0066] The first sealant 214 connects the cover plate 215 and the middle plate 20, and covers two filler sealants. The cover plate 215 is located on the side of the middle plate 20 covered by the first sealant 214, and covers the first speaker 207, battery 209, second speaker 208, second circuit board 203, first connecting circuit board 211, second connecting circuit board 212, and third connecting circuit board 213. The cover plate 215 is fixedly connected to the middle plate 20 by the first sealant 214. In this embodiment, the cover plate 215 can be a non-bendable display screen. When the electronic device 1000 is in a folded state, the electronic device 1000 can display text, images, and videos through the cover plate 215. With this setting, users can use the electronic device 1000 to view text, images, or videos in different usage scenarios, which is beneficial to improving the user experience. In addition, when the cover plate 215 is a non-bendable display screen, the electronic device also includes a fourth connecting circuit board (not shown). The fourth connecting circuit board is electrically connected between the cover plate 215 and the first circuit board 202. In some other embodiments, the cover 215 may also be a battery cover.

[0067] In this embodiment, along the thickness direction of the middle plate 20, by mounting the first circuit board 202 on one side of the middle plate 20 and mounting components such as the first speaker 207, battery 209, second speaker 208, and second circuit board 203 on the other side of the middle plate 20, the side of the middle plate 20 away from the first circuit board 202 can have a larger installation space. This increases the effective cavity space inside the housing 201 for mounting the components of the electronic device 1000, thereby making full use of the overall space of the electronic device 1000 to install more components. This helps to promote the thinner and lighter design of the electronic device 1000 and improve the user experience.

[0068] Meanwhile, the inner wall of the frame 10 of the electronic device 1000, the middle plate 20, the first speaker 207, the cover plate 215, and the first sealant 214 enclose and form the rear acoustic cavity of the first speaker 207. The battery 209, the second speaker 208, the second circuit board 203, the first connecting circuit board 211, the second connecting circuit board 212, and the third connecting circuit board 213 of the electronic device 1000 are all spaced apart from the rear acoustic cavity of the first speaker 207. With this arrangement, a complete cavity is formed inside the electronic device 1000 to serve as the rear acoustic cavity of the first speaker 207. Since the first speaker 207 and the first circuit board 202 are respectively installed on opposite sides in the thickness direction of the middle plate 20, the first circuit board 202 does not occupy the cavity space of the rear acoustic cavity of the first speaker 207, thereby increasing the effective cavity space of the rear acoustic cavity of the first speaker 207, which in turn enhances the sound quality of the first speaker 207 and improves the user's audio experience. At the same time, it can also make the gap between the cover plate 215 and the middle plate 20 smaller, so that the cover plate 215 will not make a sound when it is pressed, thus effectively solving the problem of abnormal noise when the cover plate 215 is pressed.

[0069] Furthermore, components such as the battery 209, the second speaker 208, the second circuit board 203, the first connecting circuit board 211, the second connecting circuit board 212, and the third connecting circuit board 213 are all spaced apart from the rear acoustic cavity of the first speaker 207. On the one hand, when the portion of the cover plate 215 opposite to the battery 209 is pressed by an external force, the air change between the cover plate 215 and the battery 209 caused by the external force will not be transmitted to the rear acoustic cavity of the first speaker 207, thus preventing the diaphragm of the first speaker 207 from vibrating. This avoids abnormal noises from the electronic device 1000 and helps improve the user experience. On the other hand, the vibration generated when the first speaker 207 is working will not affect the portion of the cover plate 215 opposite to the battery 209, thereby preventing the cover plate 215 from vibrating and affecting the battery 209 when the first speaker 207 is working.

[0070] In addition, when it is necessary to replace or repair the components located on the side of the middle plate 20 away from the first circuit board 202, on the one hand, it is only necessary to remove the cover plate 215 from the housing 201, without disassembling the display screen 100 inside the electronic device 1000. The operation is simple and convenient, which can avoid damage to the display screen 100, thereby helping to extend the service life of the electronic device, and also ensure the sealing integrity of the electronic device 1000, avoid damaging the sound quality of the electronic device 1000, and ensure a better audio experience for users.

[0071] In this embodiment, the electronic device 1000 may further include a functional device 217. The functional device 217 passes through the clearance hole 101 and is mounted on the side of the first circuit board 202 facing the middle plate 20, and is electrically connected to the first circuit board 202. For example, the functional device 217 may be a camera. This configuration allows the mounting space of the functional device 217 to be reused with the mounting space of the first circuit board 202 and the first speaker 207, which also helps to reduce the thickness of the electronic device 1000, promoting a thinner and lighter design and improving the user experience. Furthermore, the functional device 217 can be replaced or repaired without disassembling the first circuit board 202 and the display screen 100 of the electronic device 1000. This simplifies the replacement or repair operation of the functional device 217 and avoids damage to the first circuit board 202 and the display screen 100 of the electronic device 100 during disassembly, thereby helping to extend the service life of the electronic device 1000.

[0072] This application also provides a method for assembling an electronic device 1000.

[0076] In this embodiment, the first circuit board 202 is mounted in the first mounting slot 102, which helps to reduce the thickness of the electronic device 1000 and facilitates a thinner and lighter design for the electronic device 1000. In some other embodiments, the first mounting slot 102 may not be provided on the middle plate 20. In this case, the first circuit board 202 is directly mounted on a surface of the middle plate 20 in the thickness direction.
