DETAILED DESCRIPTION

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

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

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

[0048] Sound modules, also known as electroacoustic modules, can be collectively referred to as sound pickup modules or sound generation modules. A sound pickup module refers to an audio input module, such as a microphone, that converts sound signals into electrical signals. A sound generation module refers to an audio output module, such as a speaker, that converts electrical signals back into sound waves, enabling sound playback and diffusion.

[0049] In the related art, there are various ways to set up the sound module of electronic devices, as well as various ways to set up the sound holes used to transmit sound. Some electronic devices with displays have the sound module located on the side of the display facing away from the cover plate. This may require opening sound holes in both the display and the position where the cover plate blocks the display. Sound from the external environment of the electronic device can be transmitted to the internal sound module through the sound holes, or the sound played by the sound module can be transmitted to the outside of the electronic device through the sound holes. However, opening holes in the display increases the process difficulty and the defective rate of the display.

[0050] The present application provides an electronic device with a display screen. The electronic device has a sound module disposed on the rear side of a cover support portion that supports an edge portion of a cover plate, and corresponding sound holes are provided in the cover plate and / or support portion. The proximity of the sound module to the sound holes improves sound transmission and input or output. Furthermore, there is no need to provide a sound hole in the display screen, and no destructive processing of the display screen is required.

[0051] The electronic device may be, but is not limited to, an earphone box, a smart watch, a scanning pen, or an electronic tablet.

[0052] In some embodiments, the electronic device is a learning device with a learning function. The electronic device can be used to collect sounds made by the user, and based on the collected sound analysis, determine whether the user's pronunciation is correct, or answer or analyze what the user said.

[0053] Please refer to Figures 1 to 12 , the electronic device of this application is described in detail below.

[0054] The electronic device includes a cover plate 10, a display screen 20, a housing structure 30, a main board, and the like.

[0055] The display screen 20 is arranged on the rear side of the cover plate 10. The cover plate 10 plays a role in protecting the display screen 20. The material of the cover plate 10 can be glass, acrylic, etc. Figure 1 、 Figure 2 The area of ​​the cover plate 10 is larger than that of the display screen 20. The cover plate 10 has a middle plate portion 11 and an edge plate portion 12 surrounding the middle plate portion 11. The display screen 20 is arranged on the rear side of the middle plate portion 11 of the cover plate 10. Figures 1 to 4 In the figure, the z1 direction indicates the front direction of the electronic device, and the z2 direction indicates the rear direction of the electronic device.

[0056] The housing structure 30 includes a housing 31, and the housing 31 includes a support portion 311. The support portion 311 is arranged on the horizontal outer side of the display screen 20, and the support portion 311 is used to provide a mounting position for the cover plate 10, such as Figures 1 to 4 As shown, the edge plate portion 12 of the cover plate 10 is mounted on the support portion 311. In other words, the support portion 311 supports the edge area of ​​the cover plate 10. The cover plate 10 and the housing structure 30 enclose a receiving groove 301, and the display screen 20 is located in the receiving groove 301. The sound module 40 is also installed in the receiving groove 301.

[0057] Reference Figure 3 、 Figure 4 The sound module 40 is located on the side of the support portion 311 facing away from the cover plate 10. Furthermore, the cover plate 10 is provided with a sound hole, or the support portion 311 of the housing 31 is provided with a sound hole, or both the cover plate 10 and the support portion 311 of the housing 31 are provided with sound holes. The sound hole connects the interior of the receiving slot 301 with the exterior of the electronic device, providing a sound transmission channel. For example, if the sound module 40 is a microphone module, when a user uses the electronic device, ambient sound can be transmitted through the sound hole to the microphone module inside the housing structure 30.

[0058] The electronic device of the present application sets the sound module 40 on the rear side of the support part 311 for supporting the edge area of ​​the cover plate 10, and sets the sound hole on the cover plate 10 and / or the support part 311. In this way, the sound module 40 can be close to the sound hole, the sound transmission path is short, the loss of sound transmission between the outside and inside of the electronic device is reduced, and the sound input or output effect of the sound module 40 is improved. In addition, there is no need to set the sound module 40 on the rear side of the display screen 20, and there is no need to open a sound hole in the display screen 20, so the processing difficulty is low and the cost is low.

[0059] In one embodiment, the sound module 40 is a sound pickup module, also known as a sound input module. For example, the sound module 40 is a microphone. The microphone module is compact and is mounted on the side of the support portion 311 of the housing 31 facing away from the cover 10. This not only places the sound pickup module closer to the sound hole, improving sound reception, but also fully utilizes the internal space of the housing structure 30, resulting in a compact overall structure. In other embodiments, the sound module 40 can also be a sound output module, such as a speaker.

[0060] Alternatively, as Figures 10 to 12 As shown, the electronic device is an earphone box with a learning function. The left and right sides of the earphone box are provided with earphone slots 321, and two earphone bodies 90 can be stored in the earphone slots 321 on both sides. The front side of the earphone box has a display area. The user can listen to words with the earphones and read the words displayed on the display screen 20 on the front side of the earphone box. The sound of the user reading the words can be transmitted to the internal sound pickup module through the sound hole on the front of the electronic device. The sound pickup module collects the sound of the user reading the words. The device analyzes and processes the collected sound to determine whether the user's reading is correct or to perform other interactions.

[0061] In one embodiment, referring to Figures 1 to 7 The front (front side) of the electronic device has a sound hole. Taking the sound module 40 as an example, external sound can enter the housing structure 30 through the hole on the front of the electronic device and then be transmitted to the sound module 40. Compared with the solution where the sound hole is located on the side (upper, lower, left, and right sides) of the electronic device, the sound hole of this embodiment is located on the front of the electronic device. When the user makes sound while looking at the display screen 20, the sound can be transmitted more directly through the sound hole to the sound module 40, resulting in a better sound reception effect.

[0062] In one embodiment, please continue to refer to Figures 1 to 7The edge plate portion 12 of the cover plate 10 and the support portion 311 of the cover shell 31 are both provided with sound holes. The sound hole provided in the edge plate portion 12 of the cover plate 10 is a first sound hole 50, and the sound hole provided in the support portion 311 is a second sound hole 60. The first sound hole 50 and the second sound hole 60 are connected. Along the front-to-back direction of the electronic device, the first sound hole 50 passes through the cover plate 10, and the second sound hole 60 passes through the support portion 311. The first sound hole 50 has openings on both the front and rear sides of the cover plate 10, and the second sound hole 60 has openings on both the front and rear sides of the support portion 311. In the case where the support portion 311 is arranged on the rear side of the edge plate portion 12 of the cover plate 10 and the sound module 40 is arranged on the rear side of the support portion 311, sound holes are provided in the edge plate portion 12 of the cover plate 10 and the support portion 311 of the face shell 31, which are penetrated in the front-to-back direction. This can provide a straighter and shorter sound transmission channel. When the sound module 40 is a sound pickup module, a better sound pickup effect can be obtained. Compared with an L-shaped sound transmission channel or a sound transmission channel with a large internal bending angle, the present embodiment provides front-to-back sound holes in the cover plate 10 and the support portion 311 of the face shell 31. The sound transmission channel is straighter and the sound transmission effect is better. Along the front-to-back direction of the electronic device, the first sound hole 50 is a through hole penetrating the edge plate portion 12 of the cover plate 10, and the second sound hole 60 is a through hole penetrating the support portion 311 of the face shell 31.

[0063] It can be understood that when sound holes are provided on the edge plate portion 12 of the cover 10 and the support portion 311 of the surface shell 31, the sound holes can be set as close to the display screen 20 as possible, which is beneficial to reducing the plane size of the electronic device and helping to control the black border area around the electronic device display screen 20 to be smaller.

[0064] In other embodiments, reference Figure 9 The edge plate portion 12 of the cover plate 10 may also be provided without the first sound hole 50. The front shell 31 also includes a shell body 312 surrounding the outer periphery of the cover plate 10. The support portion 311 is connected to the inner side of the shell body 312. A mounting step is formed between the front side of the support portion 311 and the inner side of the shell body 312. The edge plate portion 12 of the cover plate 10 is mounted on this mounting step. The shell body 312 is provided with a notch to enclose the first sound hole 50 between the inner wall of the shell body 312 and the outer wall of the cover plate 10. Correspondingly, a second sound hole 60 is provided between the support portion 311 and the shell body 312. The first sound hole 50 and the second sound hole 60 are connected through and communicate with each other, thereby providing a sound transmission channel between the inside and outside of the electronic device. In the front-to-back direction of the electronic device, the first sound hole 50 is a through hole that penetrates the shell body 312 of the cover plate 31, and the second sound hole 60 is a through hole that penetrates the support portion 311 of the cover plate 31.

[0065] In one embodiment, when the cover plate 10 is provided with the first sound hole 50, the diameter of the first sound hole 50 is between 0.8 mm and 1.0 mm. Of course, in other embodiments, the diameter of the first sound hole 50 may also be other values.

[0066] In one embodiment, referring to Figure 2 、 Figure 4 、 Figure 9 In the case where the support portion 311 is provided with a second sound hole 60, the front end of the second sound hole 60 is connected to the outside of the electronic device, and the rear end of the second sound hole 60 is connected to the internal receiving groove 301 of the shell structure 30, the sound module 40 is aligned with the second sound hole 60. In other words, the sound module 40 is at least partially located behind the second sound hole 60, which helps shorten the sound transmission path and achieve direct sound in and out. Taking the sound module 40 as an example, the sound transmitted from the second sound hole 60 to the rear can be directly transmitted to the sound pickup module. The proximity of the sound pickup module to the second sound hole 60 has a good sound pickup effect. Compared with the solution of placing the sound module 40 close to the second sound hole 60 but to the side of the second sound hole 60, in this embodiment, the sound module 40 is placed behind the second sound hole 60, and the sound transmission path between the outside of the electronic device and the sound module 40 is shorter and more direct.

[0067] It should be noted that the sound module 40 can be completely located on the rear side of the second sound hole 60, or partially located on the rear side of the second sound hole 60 and partially located on the rear side of the support part 311, or completely located on the rear side of the support part 311. When the sound module 40 is located on the rear side of the support part 311, a corresponding sound transmission channel is set to allow sound to be transmitted between the second sound hole 60 and the sound module 40.

[0068] When the first sound hole 50 is provided in the edge plate portion 12 of the cover plate 10, or when the first sound hole 50 is provided in the shell body 312 of the face shell 31, the front opening of the first sound hole 50 is the first front opening 501, and the rear opening of the second sound hole 60 is the first rear opening 502. When the second sound hole 60 is provided in the support portion 311, the front opening of the second sound hole 60 is the second front opening 601, and the rear opening of the second sound hole 60 is the second rear opening 602.

[0069] In the case of a first sound hole 50 and a second sound hole 60, in order to prevent external destructive objects (such as a thin rod) from penetrating through the first sound hole 50 or the second sound hole 60 and entering the interior of the housing structure 30, thereby damaging the sound module 40 or other components inside, a protective design is implemented to shield the first sound hole 50 and / or the second sound hole 60 from destructive objects. The following provides some examples of protective designs to prevent destructive objects from entering.

[0070] In one embodiment, referring to Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 At least a portion of the wall of the second sound hole 60 is tilted to form a blocking slope 61, which prevents external destructive objects (such as Figure 5 When a thin rod (shown in FIG) is inserted into the first sound hole 50 from the front side of the first sound hole 50, the blocking slope 61 is used to provide resistance to the continued inward insertion of the damaging object, thereby preventing damage to the sound module 40 or other electronic components located behind the second sound hole 60. The blocking slope 61 is inclined from the side close to the first sound hole 50 to the side away from the first sound hole 50 toward the centerline of the second sound hole 60. That is, the blocking slope 61 is inclined from front to back toward the middle of the second sound hole 60. At least a portion of the blocking slope 61 is located behind the first sound hole 50. In this way, after the damaging object passes through the first sound hole 50, it will hit the blocking slope 61 of the second sound hole 60 and cannot be inserted further smoothly, thereby protecting the internal components.

[0071] Optionally, the diameter of the second sound hole 60 decreases from the side close to the cover plate 10 to the side away from the cover plate 10. When the sound module 40 is a sound pickup module and the diameter of the second sound hole 60 decreases from front to back, the second sound hole 60 serves to collect sound, and the blocking slope 61 not only serves to block damage but also helps to improve the sound pickup effect.

[0072] Optionally, the hole walls of the second sound hole 60 and the first sound hole 50 are smooth and have no protrusions, thereby ensuring that when sound is transmitted from the outside to the inside, the sound transmission is smooth and unobstructed or the obstruction is small, thereby improving the sound reception effect.

[0073] Alternatively, please continue to refer to Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 The hole wall of the first sound hole 50 is a straight wall extending forward and backward, and the hole wall of the first sound hole 50 is not provided with an inclined surface. In this way, the first sound hole 50 is more beautiful in appearance of the electronic device.

[0074] In other embodiments, both the first sound hole 50 and the second sound hole 60 may be provided with the blocking slope 61 , or only the first sound hole 50 may be provided with the blocking slope 61 , or neither the first sound hole 50 nor the second sound hole 60 may be provided with the blocking slope 61 .

[0075] In one embodiment, a stopper is provided on the inner wall of the second sound hole 60. The stopper protrudes relative to the inner wall of the sound hole, and at least a portion of the stopper is located behind the first sound hole 50. Thus, when a vandal is inserted into the second sound hole 60, it will hit the protruding stopper, thereby preventing further insertion. In other embodiments, neither the first sound hole 50 nor the second sound hole 60 has a stopper.

[0076] In one embodiment, please refer to Figure 3 、 Figure 4 The first sound hole 50 and the second sound hole 60 are staggered. The hole center line of the first sound hole 50 is the first hole center line (not shown in the figure), and the hole center line of the second sound hole 60 is the second hole center line (not shown in the figure). There is a gap between the first hole center line and the second hole center line, that is, the two hole center lines are staggered.

[0077] Optionally, a portion of the second sound hole 60 is aligned with the first sound hole 50, and a portion of the second sound hole 60 is aligned with the cover plate 10. In this way, after external sound enters the first sound hole 50, it can be transmitted to the second sound hole 60 and then to the sound module 40 through the second sound hole 60. A portion of the second sound hole 60 is aligned with the cover plate 10. When an external destructive object is inserted into the first sound hole 50 and tends to continue to be inserted into the second sound hole 60, the cover plate 10 has a certain blocking effect on the destructive object.

[0078] It should be noted that the drawings of the present application illustrate that there is a certain horizontal misalignment between the first rear side opening 502 on the rear side of the first sound hole 50 and the second front side opening 601 on the front side of the second sound hole 60. In other embodiments, the first rear side opening 502 and the second front side opening 601 can also be configured as: the aperture sizes are consistent and aligned.

[0079] In one embodiment, please refer to Figures 10 to 12 , the sound hole is set on the left side of the display screen 20, so that Figure 11 As shown, the user uses his right hand to touch the area corresponding to the central plate portion of the cover 10 (i.e. Figure 11 When performing touch operations (in the area marked with shaded dots, which corresponds to the location of display screen 20), the user can prevent the sound hole from being blocked by the user, thereby preventing sound transmission from being affected. For example, sound module 40 is a sound pickup module, and the sound hole is positioned to the left of display screen 20. This prevents the user's right hand from blocking the front of the sound hole when operating display screen 20. This would prevent the user's right hand from blocking the front of the sound hole, preventing the sound of the user reading or speaking from being smoothly transmitted through the sound hole to the sound pickup module, thus affecting the sound reception effect.

[0080] It should be noted that this application Figures 10 to 12 In the figure, "AA" in the area of ​​the center portion of the cover plate 10 corresponding to the display 20 is merely used to indicate the display content on the display 20, facilitating identification of the left side of the display 20. The display 20 has a left side, an upper side, a right side, and a lower side, which are sequentially connected. The sound hole being located on the left side of the display 20 means that, when viewing the display 20 from the front of the electronic device, the sound hole opening is located on the side of the left side of the display 20 facing away from the right side. When the first sound hole 50 is provided on the cover plate 10 or the main body 312 of the front housing 31, the front opening of the first sound hole 50 is located on the left side of the display 20.

[0081] For example, in an electronic device with a learning function, if a user blocks the front side of the sound hole while performing a touch operation with their right hand, if the user simultaneously reads a word or a sentence, the sound module 40 may not record the user's voice clearly, resulting in an inability to correctly identify whether the user is correctly following the word or sentence, affecting the normal use of the electronic device's learning function. In this embodiment, the sound hole is set to the left side of the display screen 20. For electronic devices with learning functions, this is conducive to the good use of the recording and learning functions. Of course, in application scenarios, setting the sound hole to the left side of the display screen 20 is also conducive to receiving or playing sound, and other application scenarios are not elaborated.

[0082] It is understood that, particularly when the electronic device is a palm-held, compact device, the advantage of locating the sound hole to the left of the display screen 20 is more pronounced. For example, when the electronic device is an earphone case or a smartwatch with a display screen 20, when a user performs touch operations, the user's hand blocks the front side of the electronic device over a large area. Locating the sound hole to the left of the display screen 20 can largely prevent users who perform touch operations with their right hand from blocking the sound hole.

[0083] In one embodiment, please refer to Figure 6 、 Figure 7 The electronic device includes a first circuit board 70, which is arranged on the side of the display screen 20 away from the cover plate 10. The first circuit board 70 is provided with a first electrical connection portion 71 and a second electrical connection portion 72. The first electrical connection portion 71 is electrically connected to the display screen 20 (not shown in the figure). Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 The second electrical connection portion 72 is electrically connected to the sound module 40. In other words, the sound module 40 and the display screen 20 share the same first circuit board 70. When assembling the electronic device, the first circuit board 70, the display screen 20, and the sound module 40 can be pre-assembled into a module, and then the module can be assembled together into the interior of the housing structure 30, which improves assembly efficiency.

[0084] Optionally, the first circuit board 70 is a flexible printed circuit board (FPC). Electronic devices with a display screen 20 typically also include other electronic components, which need to be connected to the main control board. The first circuit board 70 is a flexible circuit board and also includes a third electrical connection portion 73, which is electrically connected to the main control board. Thus, the display screen 20 is connected to the main control board via the flexible circuit board. FPCs offer excellent flexibility and bendability, adapting to various complex installation environments and space constraints. FPC connections offer improved reliability and durability. In this embodiment, the sound module 40 and the display screen 20 share a single flexible circuit board, eliminating the need for separate cables to connect the sound module 40 to the main control board. This simplifies the structure, simplifies assembly, and reduces costs. Of course, in other embodiments, the first circuit board 70 can also be a rigid printed circuit board (PCB).

[0085] In one embodiment, please refer to Figure 3 、 Figure 4 、 Figures 6 to 8 The sound module 40 is a pickup module, and is a sub-board module. That is, the pickup module is located on the side of the second electrical connection portion 72 facing away from the support portion 311. The second electrical connection portion 72 of the first circuit board 70 is located closer to the support portion 311 of the front housing 31 and the cover 10 than the pickup module. Thus, by securing the pickup module to the rear side of the second electrical connection portion 72 and then securing the second electrical connection portion 72 to the rear side of the support portion 311, the pickup module is installed, making installation quick and easy.

[0086] The sound pickup module has a sound receiving portion 41 for collecting external sounds. The sound receiving portion 41 is located on the side of the sound pickup module close to the support portion 311. Accordingly, the second electrical connection portion 72 is provided with a first clearance hole 721. The sound receiving portion 41 is exposed through the first clearance hole 721, so that the sound receiving portion 41 faces the second sound hole 60. Sounds outside the electronic device can be transmitted to the sound receiving portion 41 of the sound pickup module through the first sound hole 50, the second sound hole 60, and the first clearance hole 721.

[0087] In other embodiments, the pickup module may also be a plate-type module, that is, the pickup module is arranged on the side of the second electrical connection portion 72 close to the support portion 311, and the sound receiving portion 41 of the pickup module is arranged on the side close to the support portion 311. In order to achieve the installation and fixation of the pickup module, the shell structure 30 also includes a middle frame 32, which is located on the rear side of the surface shell 31. The pickup module is arranged between the surface shell 31 and the middle frame 32. The second electrical connection portion 72 is fixed to the middle frame 32, and the pickup module is fixed to the side of the second electrical connection portion 72 close to the support portion 311. In order to protect the pickup module, a buffer structure, such as foam, is also required to be provided between the support portion 311 and the pickup module.

[0088] In one embodiment, please continue Figure 3 、 Figure 4 、 Figures 6 to 8 When the first circuit board 70 is a flexible circuit board, the sound pickup module is arranged on the side of the second electrical connection part 72 away from the support part 311, and the second electrical connection part 72 needs to be installed and fixed on the side of the support part 311 away from the cover 10, the electronic device also includes a reinforcement structure 81, and the reinforcement structure 81 is fixed between the support part 311 and the second electrical connection part 72. The reinforcement structure 81 is provided with a second avoidance hole 811, and the second avoidance hole 811 is used to provide a sound propagation channel. The first sound hole 50, the second sound hole 60, the second avoidance hole 811, and the first avoidance hole 721 are connected, so that external sound can be transmitted to the sound receiving part 41 of the sound pickup module.

[0089] Illustratively, the reinforcement structure 81 is a reinforcement plate, which may be, but is not limited to, a metal plate or a plastic plate. The reinforcement plate has a greater structural strength than the flexible printed circuit board, thereby supporting the flexible printed circuit board and allowing the second electrical connection portion 72 of the flexible printed circuit board to be stably mounted on the rear side of the support portion 311. When assembling the electronic device, the sound module 40, display 20, first circuit board 70, and reinforcement plate can be pre-assembled into a module, which can then be integrally installed within the housing structure 30.

[0090] In one embodiment, please continue Figure 3 、 Figure 4 、 Figures 6 to 8 The electronic device further includes a dustproof net 82, which is fixed between the support portion 311 and the second electrical connection portion 72. The dustproof net 82 is used to prevent external dust from falling onto the sound module 40, ensuring that the sound module 40 works normally.

[0091] In one embodiment, an adhesive layer 83 is further included, and the rear side of the edge plate portion 12 of the cover plate 10 is fixed to the support portion 311 via the adhesive layer 83. The adhesive layer 83 is a waterproof adhesive layer 83. The adhesive layer 83 can be a waterproof double-sided tape or a structure formed by curing waterproof glue.

[0092] It is understood that a waterproof layer is provided between the edge plate portion 12 of the cover plate 10 and the support portion 311 of the face shell 31. This prevents moisture from outside the electronic device from entering the receiving groove 301 within the housing structure 30 after the cover plate 10 is installed on the face shell 31, thereby preventing damage to the display screen 20, the sound module 40, or other electronic components. In this solution, the sound module 40 is installed behind the support portion 311, rather than directly behind the edge plate portion 12 of the cover plate 10. This allows for a waterproof layer to be provided between the edge plate portion 12 of the cover plate 10 and the support portion 311 of the face shell 31, ensuring waterproof performance.

[0093] In one embodiment, please continue Figure 3 、 Figure 4 、 Figures 6 to 8 The electronic device includes a dust screen 82 and a reinforcement structure 81. Adhesive layers 83 are provided between the edge plate portion 12 of the cover 10 and the support portion 311, between the support portion 311 and the dust screen 82, and between the dust screen 82 and the reinforcement structure 81. The adhesive layers 83 may be, but are not limited to, double-sided tape. Furthermore, each adhesive layer 83 is provided with a clearance hole to ensure a sound transmission path from the first sound hole 50 to the sound module 40.

[0094] In one embodiment, the housing structure 30 further includes a middle frame 32 and a rear housing 33. The middle frame 32 is disposed on the side of the front housing 31 facing away from the cover 10, and the rear housing 33 is disposed on the side of the middle frame 32 facing away from the front housing 31. The sound module 40 is disposed between the support portion 311 of the front housing 31 and the middle frame 32. The display 20 is disposed between the cover 10 and the middle frame 32. The main control board (not shown) is disposed between the middle frame 32 and the rear housing 33.
