electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on April 28, 2023, with application number 202310486116.X and application name “Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of electronic equipment, and in particular to an electronic device including a speaker module. Background Art

[0003] Speaker modules are used to convert audio electrical signals such as music and voice into sound. They can support the function of external audio playback and are widely used in electronic devices such as mobile phones, tablets, and laptops.

[0004] However, the thickness of the speaker module is relatively thick, which is contrary to the demand for ultra-thin electronic devices. Therefore, how to achieve an ultra-thin design of the entire device by reducing the thickness of the speaker module is a technical problem that needs to be solved urgently.

[0005] Summary of the Invention

[0006] In order to solve the above technical problems, the present application provides an electronic device that can realize a lightweight and thin design of the electronic device and has a good sealing effect.

[0007] An embodiment of the present application provides an electronic device, which includes a middle frame, a display module, a back cover, a speaker module, a sealing bracket and a first annular sealing member; the middle frame includes an appearance member and a support member, the appearance member is annular, the support member is located inside the appearance member, and the appearance member is provided with a sound outlet; the support member is located between the display module and the back cover, and the display module, the appearance member of the middle frame and the back cover form a whole machine; the speaker module is located in the cavity of the whole machine and is located on one side of the support member along a first direction, the speaker module includes a side shell and a core, the side shell is annular, the core is located inside the side shell, and the area surrounded by the side shell is divided into a front cavity and a rear cavity; along the first direction, the side shell includes relative first and second shells. a surface and a second surface, the side shell further comprising an outer surface and an inner surface connecting the first surface and the second surface, a sound outlet channel being provided on the side shell, the sound outlet channel penetrating the outer surface and the inner surface, and extending to the second surface along the first direction, the sound outlet channel connecting the front cavity and the sound outlet hole; the sealing bracket is located in the gap between the appearance part and the side shell, the sealing bracket is annular to expose the sound outlet hole and the sound outlet channel; the first annular seal is located between the second surface of the side shell and the support part, as well as between the sealing bracket and the support part; the area enclosed by the core, the inner surface of the side shell, the support part, the sealing bracket and the first annular seal forms a front cavity; the first direction is perpendicular to the plane where the support part is located.

[0008] Since the sound outlet channel is provided on the side shell and extends to the second surface of the side shell, when only the first annular seal is provided between the second surface of the side shell and the support member, the gas in the front cavity will be transmitted through the sound outlet channel to the gap between the sealing bracket and the support member, and then transmitted to the entire cavity through the gap between the sealing bracket and the support member, causing problems such as vibration of the display module, high-frequency drop, and poor waterproofing of the entire device. In the embodiment of the present application, not only is the first annular seal provided between the second surface of the side shell and the support member, but the first annular seal also extends to the gap between the sealing bracket and the support member to achieve sealing of the gap between the sealing bracket and the support member. In this way, an open front cavity (which is beneficial for reducing the thickness of the electronic device) can be achieved while also ensuring the sealing effect of the front cavity.

[0009] Exemplarily, the first direction is the direction from the display module to the back cover, that is, the thickness direction of the electronic device, ie, the Z-axis direction in the embodiment.

[0010] For example, when the electronic device is a mobile phone, a tablet computer, a laptop computer, a car computer, a smart wearable device, etc., the back cover is, for example, a battery cover.

[0011] For example, the electronic device may be a flat electronic device or a foldable electronic device. When the electronic device is a foldable electronic device, the display module may be a flexible screen and the back cover may be an external screen.

[0012] In some possible implementations, the sealing bracket includes a support portion and a sealing portion, both of which are annular. The sealing portion is fixed to the side of the support portion facing away from the exterior component. This simple structure of the sealing bracket facilitates assembly and ensures a good seal in the gap between the side housing and the exterior component.

[0013] In some possible implementations, based on the sealing bracket including a supporting portion and a sealing portion, the electronic device further includes a blocking structure located in a gap surrounded by the supporting portion, the side housing, the sealing portion and the first annular seal.

[0014] Because the annular sealing portion has a certain thickness in the direction away from the support portion (i.e., the Y-axis direction in this embodiment), a gap exists between the support portion, the side housing, the sealing portion, and the first annular sealing member. To prevent gas in the front chamber from leaking into the entire device cavity through this gap, a blocking structure is provided within the gap enclosed by the support portion, the side housing, the sealing portion, and the first annular sealing member. This blocking structure prevents gas in the front chamber from being transmitted through this gap into the entire device cavity, further ensuring a good sealing effect.

[0015] In some possible implementations, when the electronic device further includes a blocking structure and the sealing bracket includes a support portion and a sealing portion, the blocking structure and the sealing portion are integrally formed. This means that the blocking structure can be prepared simultaneously with the sealing portion, eliminating the need for a separate blocking structure. This simplifies the process and reduces costs. Furthermore, it ensures that there is no gap between the blocking structure and the annular sealing portion, thereby ensuring a good sealing effect.

[0016] Of course, the blocking structure and the sealing portion can also be formed separately.

[0017] In some possible implementations, the electronic device further includes a blocking structure, wherein the blocking structure is elongated and, along a first direction, opposite ends of the elongated blocking structure contact the sealing portion and the first annular seal, respectively; and along a second direction, opposite sides of the elongated blocking structure contact the side housing and the support portion, respectively, with the second direction being perpendicular to the first direction. The blocking structure has a simple structure.

[0018] Exemplarily, the second direction is the Y-axis direction in the embodiment.

[0019] In some possible implementations, the electronic device further includes a blocking structure, and the sealing portion has an opening. The sealing portion includes a first end and a second end located on either side of the opening. The blocking structure is located between the first end and the first annular seal, and between the second end and the first annular seal. This simplifies the structure of the sealing portion, saves materials, and reduces costs.

[0020] Exemplarily, the sealing portion and the blocking structure are in a "U" shape.

[0021] In some possible implementations, the electronic device further includes a blocking structure, wherein the blocking structure has a width in a third direction that is greater than or equal to 0.6 mm and less than or equal to 2 mm; the third direction is perpendicular to the first direction. This configuration ensures that the blocking structure is neither too narrow to compromise sealing nor too wide to occupy the entire device cavity.

[0022] Exemplarily, the third direction is the X-axis direction in the embodiment.

[0023] Exemplarily, the width of the blocking structure in the third direction includes 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm or 2 mm.

[0024] In some possible implementations, the electronic device further includes a blocking structure, and the blocking structure includes a material such as glue or soft glue that can achieve a sealing effect.

[0025] In some possible implementations, on the basis that the electronic device also includes a blocking structure, when the blocking structure includes soft glue, when the blocking structure is located in the gap surrounded by the support part, the side shell, the sealing part and the first annular seal, compression interference is formed between the blocking structure and the support part, the side shell, the sealing part and the first annular seal to further ensure the sealing effect and prevent the front cavity air from leaking through the gap between the blocking structure and the support part, the gap between the side shell, the gap between the sealing part, and the gap between the first annular seal.

[0026] In some possible implementations, on the basis that the electronic device also includes a blocking structure, an auxiliary structure is provided at the area where the blocking structure is connected to the first annular seal, and the auxiliary structure is used to shield the area where the blocking structure is connected to the first annular seal. The area where the blocking structure is connected to the first annular seal is sealed by the auxiliary structure to prevent the air in the front cavity from leaking through the gap between the blocking structure and the first annular seal.

[0027] In some possible implementations, an auxiliary structure is provided at the region where the blocking structure is connected to the first annular seal, and the auxiliary structure includes a weakly sticky glue such as silicone glue or UV glue.

[0028] In some possible implementations, an auxiliary structure is provided at the region where the blocking structure is connected to the first annular seal. The auxiliary structure is formed by a glue dispensing process, has a simple structure, and has a good sealing effect.

[0029] In some possible implementation methods, based on the provision of an auxiliary structure in the area where the blocking structure is connected to the first annular seal, the auxiliary structure is located on the outside of the front cavity. This facilitates the setting of the auxiliary structure. That is, after completing the assembly of the speaker module and the first annular seal, the auxiliary structure is directly set in the area where the blocking structure is connected to the first annular seal. The setting method is simple and reduces the process difficulty.

[0030] In some possible implementations, a support hole is formed in the support member, and an orthographic projection of the support hole on the plane where the support member is located overlaps with an orthographic projection of the core on the plane where the support member is located. The electronic device also includes a second annular seal, which is located between the support member and the display module and is arranged around the edge of the support hole. The provision of the support hole can further increase the volume of the front cavity. In this way, while maintaining the volume of the front cavity, the core can be moved further downward, the size of the side shell in the first direction becomes smaller, the back cover can be moved further downward, and the distance between the display module and the back cover becomes shorter, which is conducive to the lightweight design of the electronic device.

[0031] Illustratively, the plane where the support member is located is the plane formed by the X-axis and the Y-axis in the embodiment.

[0032] In some possible implementations, the support member is provided with a support hole, the orthographic projection of the support hole on the plane of the support member overlapping the orthographic projection of the core on the plane of the support member. The electronic device further includes a second annular seal positioned between the support member and the display module and surrounding the edge of the support hole. The display module is attached to the support member via an adhesive layer, the adhesive layer serving as the second annular seal. This eliminates the need for a separate second annular seal, simplifies the structure, and reduces costs.

[0033] In some possible implementations, the rear cavity is connected to the entire cavity of the electronic device to increase the volume of the rear cavity, that is, the entire cavity of the electronic device serves as the rear cavity of the speaker module, which can achieve better audio effects in the limited architectural space of the electronic device.

[0034] In some possible implementations, the first annular seal includes a first edge and a second edge, the second edge being disposed around the first edge, and a distance W1 between the first and second edges, where 0.8 mm ≤ W1 ≤ 2 mm. In other words, the width of the first annular seal is between 0.8 mm and 2 mm. This ensures that the first annular seal is neither too narrow to provide a seal, nor too wide to occupy excessive space within the device cavity.

[0035] Exemplarily, the distance W1 between the first edge and the second edge is 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm or 2 mm, etc.

[0036] In some possible implementations, the first annular sealing member includes foam, foam adhesive, glue, or adhesive. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The embodiments of the present application provide an electronic device. The electronic device provided in the embodiments of the present application can be a mobile phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), an in-car computer, a television, a smart wearable device (such as a smart watch, a smart bracelet, a smart head-mounted display, smart glasses), a smart home device, or other device including a speaker module. The embodiments of the present application do not specifically limit the specific form of the above-mentioned electronic device. For the convenience of explanation, the following description takes the electronic device as an example.

[0073] Referring to Figures 1 and 2 , Figure 1 is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application, and Figure 2 is an exploded view of the electronic device shown in Figure 1 . As shown in Figures 1 and 2 , a mobile phone 100 includes a display module 10, a back cover (also called a battery cover) 20, a midframe 30, a main board 40, a sub-board 50, a flexible printed circuit (FPC) 60 connecting the main board 40 and the sub-board 50, a battery 70, and at least one speaker module 80, among other structures.

[0074] It should be understood that Figures 1 and 2 and the related figures below merely schematically illustrate some of the components of mobile phone 100, and the actual shape, size, location, and structure of these components are not limited by Figures 1 and 2 or the figures below. Furthermore, when the electronic device is of some other form factor, electronic device 100 may also not include at least one of the display module 10, back cover 20, middle frame 30, sub-board 50, FPC 60, and battery 70.

[0075] In Figures 1 and 2, the mobile phone 100 is in the shape of a rectangular flat plate. In order to facilitate the clear description of the subsequent structural features and the positional relationship of the structural features, the positional relationship of the various structures in the mobile phone is specified in terms of the X-axis direction, the Y-axis direction, and the Z-axis direction, wherein the X-axis direction is the width direction of the mobile phone, the Y-axis direction is the length direction of the mobile phone, and the Z-axis direction is the thickness direction of the mobile phone. It is understandable that the coordinate system (i.e., the X-axis, Y-axis, and Z-axis) of the electronic device can be flexibly set according to actual needs and is not specifically limited here. In other optional embodiments, the shape of the electronic device can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc. Of course, the electronic device can also be a foldable electronic device, etc.

[0076] Continuing with FIG2 , the display module 10 includes a cover plate 11 and a display screen 12 stacked along the Z-axis. The cover plate 11 protects the display screen 12, for example. The display screen 12 includes, for example, a liquid crystal display (LCD), an organic light emitting diode (OLED) display, and an LED display. Examples of LED displays include micro-LED displays and mini-LED displays. The present embodiment does not limit the type of display screen 12.

[0077] Along the Z-axis, the back cover 20 is located on the side of the display screen 12 facing away from the cover plate 11. The back cover 20 can be made of, for example, opaque materials such as plastic, plain leather, and fiberglass, or can be made of translucent materials such as glass. The present embodiment does not limit the material of the back cover 20.

[0078] The middle frame 30 is located between the cover plate 11 and the back cover 20. The middle frame 30 includes an annular appearance part 31 and a support member 32 located within the annular appearance part 31 and between the display screen 12 and the back cover 20. The cover plate 11, the annular appearance part 31, and the back cover 20 can enclose the entire device cavity. Structures such as the display screen 12, the main board 40, the sub-board 50, the FPC 60, the battery 70, and the speaker module 80 are located within the entire device cavity, and the structures within the entire device cavity are supported by the support member 32. Exemplarily, the display module 10 is set on the support member 32, for example, via an adhesive layer (13 in Figure 7 below), and the speaker module 80 and the sub-board 50 are located on the side of the support member 32 facing away from the display screen 12. The display screen 12, the speaker module 80, and the sub-board 50 are supported by the support member 32, wherein the adhesive layer, for example, is a backing adhesive, which can be used to set the display screen 12 on the support member 32.

[0079] Along the Y-axis direction, the main board 40 and the sub-board 50 are respectively arranged on both sides of the battery 70 , and the FPC 60 passes through the battery 70 to electrically connect the main board 40 and the sub-board 50 to realize the transmission of data and signals between the main board 40 and the sub-board 50 .

[0080] The motherboard 40 is integrated with a control chip. The control chip includes, for example, a system on chip (SoC) and an application processor (AP). The SoC may include, for example, a central processing unit (CPU), a graphics processing unit (GPU), and a modem.

[0081] The sub-board 50 integrates an antenna radio frequency front end, a Universal Serial Bus (USB) device, and the like.

[0082] The battery 70 is used to supply power to components in the mobile phone 100 , such as the display screen 12 , components on the main board 40 , components on the sub-board 50 , and the speaker module 80 , to ensure normal operation.

[0083] The speaker module 80 is used to convert audio signals such as music and voice into sound, and can support the function of playing audio externally. Along the Y-axis direction, the speaker module 80 is located on the side of the battery 70 away from the main board 40, that is, it is arranged adjacent to the sub-board 50 and is electrically connected to the sub-board 50. In this case, the audio signal sent by the main board 40 is transmitted to the speaker module 80 via the FPC 60 and the sub-board 50, and is converted into sound output by the speaker module 80. Specifically, the speaker module 80 has a sound output channel 81, and accordingly, a sound output hole 300 is opened on the middle frame 30, which is connected to the sound output channel 81. The sound converted by the speaker module 80 is output by the sound output channel 81 and further output to the outside of the mobile phone 100 through the sound output hole 300.

[0084] It should be noted that Figures 1 and 2 illustrate an example in which there is one speaker module 80, and that the speaker module 80 is located on the side of the battery 70 facing away from the main board 40. In other optional embodiments of the present application, the speaker module 80 may also be disposed adjacent to the main board 40 and electrically connected thereto. In this case, the main board 40 transmits the audio signal to the speaker module 80 electrically connected thereto, which is converted into sound output by the speaker module 80. Alternatively, the number of speaker modules 80 may be greater than or equal to two, with at least one speaker module 80 disposed adjacent to and electrically connected to the sub-board 50, and at least one speaker module 80 disposed adjacent to and electrically connected to the main board 40.

[0085] Referring to Figures 3 and 4, Figure 3 is a structural schematic diagram of a speaker module, and Figure 4 is a cross-sectional view of the speaker module shown in Figure 3 along the AA' direction. As shown in Figures 3 and 4, the speaker module 80 includes a shell 82 and a core 83. Along the Z-axis direction, the shell 82 includes a front shell 821 and a rear shell 822 that are relatively arranged, and the front shell 821 is located between the rear shell 822 and the display screen 12. The shell 82 also includes a side shell 823 connecting the front shell 821 and the rear shell 822. The side shell 823 is, for example, integrally formed with the front shell 821, and then assembled with the rear shell 822 to form the shell 82. This helps to reduce the difficulty of molding and assembling the shell 82.

[0086] The front housing 821 includes a front cavity wall 8211 and an annular front cavity step 8212 disposed around the front cavity wall 8211. The annular front cavity step 8212 may be a plastic component, and the front cavity wall 8211 may be a metal component. For example, the front cavity wall 8211 is made of stainless steel. The front cavity wall 8211 and the annular front cavity step 8212 may be an integral structure, i.e., the front cavity wall 8211 and the annular front cavity step 8212 may be integrally formed. For example, the annular front cavity step 8212 may be formed on the front cavity wall 8211 using an injection molding process. Alternatively, the front cavity wall 8211 may be attached to the annular front cavity step 8212 by bonding, clamping, screws, etc. By providing the front cavity wall 8211, the overall structural strength of the front housing 821 may be improved without increasing the thickness of the front housing 821.

[0087] The side shell 823 includes two first side walls 8231 arranged opposite to each other along the X-axis direction and two second side walls 8232 arranged opposite to each other along the Y-axis direction. During assembly, a sound outlet channel 81 is formed between one of the second side walls 8232 and the annular front cavity step 8212. In this way, there is no need to set up a separate sound outlet channel 81, which reduces the difficulty of assembly.

[0088] The front housing 821, rear housing 822, and side housing 823 form a housing cavity. The core 83 is disposed within the housing 82 and divides the housing cavity of the housing 82 into a front cavity Q1 and a rear cavity Q2. The front cavity Q1 communicates with the sound outlet 81. A ventilation channel (not shown) is provided between the core 83 and the rear cavity Q2, connecting the core 83 and the rear cavity Q2 to facilitate ventilation.

[0089] The core 83 includes a bracket, a diaphragm system, a voice coil, and a magnetic circuit system. The diaphragm system includes a dome and a diaphragm. The core 83 uses the diaphragm system to separate the front cavity Q1 and the rear cavity Q2 of the speaker module 80. The bracket is used to support the diaphragm system and fix the magnetic circuit system. The magnetic circuit system is used to cooperate with the voice coil to drive the diaphragm group to vibrate. The diaphragm system can drive the air in the front cavity Q1 to vibrate. The vibrating air in the front cavity Q1 is discharged from the sound outlet channel 81 to form sound, and the sound is further discharged to the outside of the mobile phone 100 through the sound outlet hole 300 connected to the sound outlet channel 81 so that it can be heard by the user. The specific structure and working principle of the core 83 are similar to those of the existing technology. Please refer to the existing technology for details and will not be repeated here.

[0090] It should be noted that Figures 3 and 4 illustrate the shell 82 as an independent shell structure, but do not constitute a limitation of the present application. In other optional embodiments of the present application, at least a portion of the shell 82 can be surrounded by other components of the electronic device. For example, refer to Figures 5 and 6, Figure 5 is a structural schematic diagram of another speaker module provided in an embodiment of the present application, and Figure 6 is a cross-sectional view of the speaker module shown in Figure 5 along the BB' direction. As shown in Figures 5 and 6, in order to achieve better audio effects in the limited architectural space of the electronic device, such as stereo sound, the speaker module can be used in an electronic device with an open sound cavity, that is, the entire cavity of the entire electronic device is used as the back cavity of the speaker module, that is, a hollow portion 8221 is provided on the rear shell 822, or the rear shell 822 is directly omitted to connect the back cavity Q2 of the speaker module 80 and the whole cavity.

[0091] As can be seen from the foregoing, the middle frame 30 is provided with a sound outlet 300 that communicates with the sound outlet channel 81. The sound converted by the speaker module 80 is output through the sound outlet channel 81 and then further output to the outside of the mobile phone 100 through the sound outlet 300. However, during the process of sound transmission from the sound outlet channel 81 to the sound outlet 300, sound may leak through the gap between the sound outlet channel 81 and the sound outlet 300.

[0092] Specifically, see Figures 7 and 8. Figure 7 is a cross-sectional view of the electronic device shown in Figure 1 along the CC' direction, and Figure 8 shows the positional relationship between the exterior member and the sealing bracket of the middle frame. As shown in Figures 7 and 8, there is a gap between the exterior member 31 having the sound outlet 300 and the second sidewall 8232 having the sound outlet channel 81, namely, region OO1 in Figure 7. Furthermore, there is a gap between the exterior member 31 having the sound outlet 300 and the annular front cavity step 8212, namely, region OO2 in Figure 7. During the process of sound being output to the sound outlet 300 via the sound outlet channel 81, to prevent sound from leaking through the gap between the exterior member 31 having the sound outlet 300 and the second sidewall 8232 having the sound outlet channel 81, and the gap between the exterior member 31 having the sound outlet 300 and the annular front cavity step 8212 (the leakage path is indicated by the dashed arrows in Figure 7), for example, if sound leaks, it vents to the rear cavity Q2, causing the phase of the air in the front cavity Q1 and the air in the rear cavity Q2 to cancel each other out, thus eliminating the sound. The middle frame 30 is also provided with a sealing bracket 33. Along the Y-axis, the sealing bracket 33 is positioned between the exterior member 31, which defines the sound outlet 300, and the second sidewall 8232, which defines the sound outlet channel 81. The sealing bracket 33 is fixed to the exterior member 31. The sealing bracket 33 includes a support portion 331 and a sealing portion 332. Both the support portion 331 and the sealing portion 332 are annular. Along the Y-axis, the annular sealing portion 332 is fixed to the side of the annular support portion 331 facing away from the exterior member 31. By configuring the support portion 331 and the sealing portion 332 in an annular shape, the sound outlet 300 is exposed, preventing obstruction. When the speaker module 80 and the middle frame 30 are assembled, the sealing bracket 33 is located on the side of the second side wall 8232 facing the appearance part 31, and the annular sealing portion 332 is arranged around the sound outlet channel 81, and is located between the second side wall 8232 with the sound outlet channel 81 and the annular support portion 331, as well as between the annular front cavity step 8212 and the annular support portion 331, that is, the OO1 area and the OO2 area in Figure 7 are sealed to prevent sound from leaking through the gap between the appearance part 31 with the sound outlet hole 300 and the second side wall 8232 with the sound outlet channel 81, as well as the gap between the appearance part 31 with the sound outlet hole 300 and the annular front cavity step 8212.

[0093] Exemplarily, the support portion 331 includes, for example, hard plastic, etc., to ensure a supporting effect on the sealing portion 332. The sealing portion 332 includes, for example, soft plastic, to ensure a sealing effect.

[0094] Currently, due to consumer demand, electronic devices need to be designed to be thinner and thinner, that is, the size of the electronic device 100 in the Z-axis direction is getting smaller and smaller. In order to achieve the lightweight and thin design of electronic devices, thinner speaker modules are needed.

[0095] FIG9 is a cross-sectional view of the electronic device shown in FIG1 along the DD' direction. As shown in FIG9 , the thickness (dimension in the Z-axis direction) of the speaker module 80 is primarily composed of the thickness H1 of the front cavity wall 8211, the height H2 of the core 83, and the clearance H3 between the front cavity wall 8211 and the support member 32 (to prevent interference between the support member 32 and the front cavity wall 8211). While thinning the core 83 can affect the performance of the speaker module 80, if the core 83 cannot be thinned, the design of the front cavity Q1 can be adjusted to achieve a thinner and lighter electronic device.

[0096] Specifically, see Figure 10, which is another cross-sectional view of the electronic device shown in Figure 1 along the DD' direction. As shown in Figure 10, the front housing 821 includes only an annular front cavity step 8212, i.e., the front cavity wall 8211 is hollowed out to form a front cavity hole 82111, thereby converting the front cavity Q1 into an open front cavity. In some embodiments, the projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis overlaps with the projection of the diaphragm system of the core 83 on the plane formed by the X-axis and the Y-axis, i.e., the design of the front cavity hole 82111 can expose the diaphragm and the dome.

[0097] It should be noted that the projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis overlaps with the diaphragm system of the core 83. This can mean that the projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis partially overlaps with the projection of the diaphragm system of the core 83 on the plane formed by the X-axis and the Y-axis; or that the projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis overlaps with the projection of the diaphragm system of the core 83 on the plane formed by the X-axis and the Y-axis; or that the projection of the diaphragm system of the core 83 on the plane formed by the X-axis and the Y-axis is located within the projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis. The meaning of overlap involved in the following embodiments is the same as this meaning and will not be repeated in the following embodiments.

[0098] When the front cavity wall 8211 is hollowed out, in the Z-axis direction, the thickness H1 of the front cavity wall 8211 and the avoidance gap H3 between the front cavity wall 8211 and the support member 32 can be omitted. In this way, while ensuring the volume of the front cavity Q1, the core 83 can be moved downward, and the size of the side shell 823 in the Z-axis direction becomes smaller, and then the back cover 20 can be moved downward, which is conducive to the lightweight design of the electronic device.

[0099] It should be noted that the so-called downward movement of the core 83 refers to the movement of the core 83 along the -Z direction in Figure 10, and the downward movement of the rear cover 20 refers to the movement of the rear cover 20 along the -Z direction in Figure 10. After the downward movement, the vertical distance (along the Z-axis direction) between the rear cover 20 and the display screen 12 is shortened, which is conducive to the lightweight and thin design of the electronic device. The meaning of downward movement involved in the following embodiments is the same as this meaning, and the following embodiments will not be repeated.

[0100] Although the open front cavity design is conducive to the lightweight design of electronic devices, it will bring about sealing problems. That is, if the sealing effect is not good, it will cause ventilation between the front cavity Q1 and the rear cavity Q2, and the air in the front cavity Q1 and the air in the rear cavity Q2 will cancel each other out, resulting in sound disappearing, vibration of the display screen 12, and poor waterproofing of the entire machine, which will affect the user experience.

[0101] Based on this, in conjunction with Figure 11, Figure 11 is a diagram showing the positional relationship between the support member and the seal provided in an embodiment of the present application. As shown in Figures 10 and 11, a first annular seal 90 is provided between the support member 32 of the middle frame 30 and the annular front cavity step 8212. The provision of the first annular seal 90 can block the air in the front cavity Q1, preventing the air in the front cavity Q1 from being transmitted to the rear cavity Q2 through the gap between the support member 32 and the annular front cavity step 8212 (the transmission path is indicated by the dotted arrow in Figure 10).

[0102] The embodiment of the present application does not limit the type of the first annular seal 90, as long as it can prevent air from passing through the gap between the support member 32 and the annular front cavity step 8212. For example, the first annular seal 90 can be made of foam, foam glue, glue, or adhesive.

[0103] To further reduce the thickness of the electronic device in the Z-axis direction, see Figure 12, which is another cross-sectional view of the electronic device shown in Figure 1 along the DD' direction. As shown in Figure 12, a support hole 321 is defined in the support member 32. The projection of the front cavity hole 82111 on the plane formed by the X-axis and the Y-axis overlaps with the projection of the support hole 321 on the plane formed by the X-axis and the Y-axis. Accordingly, the adhesive layer 13 is also hollowed out.

[0104] The provision of the support hole 321 can further increase the volume of the front cavity Q1. In this way, while ensuring the volume of the front cavity Q1, the core 83 can be further moved downward, the size of the side shell 823 in the Z-axis direction becomes smaller, and the back cover 20 can be further moved downward, which is conducive to the lightweight design of the electronic device. The gap between the display screen 12 and the support member 32 is sealed by the adhesive layer 13 to prevent the air in the front cavity Q1 from leaking through the gap between the display screen 12 and the support member 32. That is, the adhesive layer reuses the sealing structure between the display screen 12 and the support member 32. In this way, there is no need to set up a separate sealing structure, simplifying the structure and reducing costs. Of course, a second annular seal can also be set up separately around the edge of the support hole 321. That is, the second annular seal can be set up separately, or the adhesive layer 13 can be reused as the second annular seal.

[0105] However, it is taken into consideration that when the inner core 83 continues to move downward, interference will be formed between the inner core 83 and the front cavity step 8212, that is, in the EE area shown in Figure 12, the gap between the inner core 83 and the front cavity step 8212 is small, so that the air in the front cavity Q1 cannot be transmitted to the sound outlet hole 300 through the sound outlet channel 81.

[0106] Based on this, refer to Figure 13, which is a schematic structural diagram of another speaker module provided in an embodiment of the present application. As shown in Figure 13, the front cavity step 8212 of the speaker module 80 is also removed. In other words, the speaker module 80 now includes an annular sidewall 823, and the core 83 is located in the space enclosed by the annular sidewall 823, and the space is divided into a front cavity Q1 and a rear cavity Q2. This configuration ensures that the thickness of the electronic device in the Z-axis direction is reduced while also avoiding interference between the core 83 and the front cavity step 8212.

[0107] However, as can be seen from the above content, the first annular seal 90 is set between the front cavity step 8212 and the support member 32 of the middle frame 30. When the front cavity step 8212 is removed, the sealing effect becomes worse. Therefore, when the front cavity step 8212 is removed, in order to ensure the sealing of the front cavity Q1, refer to Figures 14 and 15. Figure 14 is another cross-sectional view of the electronic device shown in Figure 1 along the DD' direction, and Figure 15 is a comparison diagram of the positional relationship between the speaker module, the sealing bracket and the first annular seal, wherein Figure 15 (1) is a structural schematic diagram when the first annular seal is not set, and Figure 15 (2) is a structural schematic diagram when the first annular seal is set. As shown in Figures 14 and 15, when the speaker module 80 does not include the front cavity step 8212, that is, when the speaker module 80 is the structure shown in Figure 13, the first annular seal 90 can be set between the side shell 823 of the shell 82 and the support member 32 of the middle frame 30 and between the annular support portion 331 and the support member 32.

[0108] Specifically, the side housing 823 includes a first surface 823a and a second surface 823b that are arranged opposite each other along the Z-axis. The first surface 823a is located on the side of the second surface 823b that faces away from the display screen 12. The sound outlet channel 81 provided on the second sidewall 8232 creates a notch in the second surface 823b (as shown in FIG13 ). The first annular seal 90 includes a first subsection 91, a second subsection 92, a third subsection 93, and a fourth subsection 94 that are continuous and connected end to end. A first portion 91 of the first annular seal 90 is provided between the second surface 823b of one of the first side walls 8231 and the support member 32 of the middle frame 30. A second portion 92 of the first annular seal 90 is provided between the second surface 823b of one of the second side walls 8232 (the second side wall 8232 without the sound outlet channel 81) and the support member 32. A third portion 93 of the first annular seal 90 is provided between the second surface 823b of the other first side wall 8231 and the support member 32 of the middle frame 30. A second surface 823b of the other second side wall 8232 (the second side wall 8232 with the sound outlet channel 81) is provided. A fourth portion 94 of the first annular seal 90 is provided between the second surface 823b of the first side wall 8231 and the support member 32, and between the sealing bracket 331 and the support member 32, to seal the gap between the second surface 823b of the first side wall 8231 and the support member 32 of the middle frame 30, the gap between the second surface 823b of the second side wall 8232 and the support member 32, and the gap between the sealing bracket 331 and the support member 32. In this way, even if the front cavity step 8212 is eliminated, the front cavity Q1 can be sealed, avoiding the problem of ventilation between the front cavity Q1 and the rear cavity Q2, which would cause the air in the front cavity Q1 and the air in the rear cavity Q2 to cancel each other out and eliminate the sound. Moreover, the elimination of the front cavity step 8212 allows the core 83 to continue to move downward, further reducing the thickness of the electronic device in the Z-axis direction, which is conducive to the lightweight design of the electronic device.

[0109] In this case, the first annular seal 90 includes a first edge 90a and a second edge 90b. The second edge 90b is disposed around the first edge 90a. The distance between the first edge 90a and the second edge 90b is W1, where 0.8mm≤W1≤2mm. In other words, the width of the first annular seal 90 is between 0.8mm and 2mm. This ensures that the first annular seal 90 is neither too narrow to provide a sealing effect nor too wide to occupy too much space in the entire device cavity.

[0110] Exemplarily, the distance W1 between the first edge 90a and the second edge 90b includes 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm or 2 mm.

[0111] It should be noted that the removal of the front cavity step 8212 in the above example is based on the premise that the support member 32 of the middle frame 30 has a support hole 321, but this does not constitute a limitation of the present application. In other optional embodiments of the present application, the removal of the front cavity step 8212 can also be based on the premise that the support member 32 of the middle frame 30 is not modified (i.e., the support hole 321 is not provided).

[0112] In this case, after research, it was found that, referring to Figures 16, 17 and 18, Figure 16 is a positional relationship diagram of the middle frame, sealing bracket, first annular seal, speaker module and display module provided in an embodiment of the present application, Figure 17 is a partial enlarged view of the SS area in Figure 16, and Figure 18 is a positional relationship diagram of the second side wall, the fourth division of the first annular seal and the sealing bracket provided in an embodiment of the present application. As shown in Figures 16, 17 and 18, since the annular sealing portion 332 has a certain thickness in the Y-axis direction, there is a gap between the annular support portion 331, the second side wall 8232, the annular sealing portion 332 and the fourth division 94 of the first annular seal 90, and the number of gaps is two. Along the Y-axis direction, the two gaps are located on both sides of the sound outlet channel 81, such as the PP area shown in Figure 17 and the TT area shown in Figure 18.

[0113] In order to prevent the gas in the front cavity Q1 from leaking into the entire machine cavity through the gap, refer to Figures 19, 20 and 21. Figure 19 is another position relationship diagram of the middle frame, sealing bracket, speaker module and display module provided in an embodiment of the present application. Figure 20 is a partial enlarged view of the VV area in Figure 19. Figure 21 is a position relationship diagram of the blocking structure, the second side wall, the fourth division of the first annular seal and the sealing bracket provided in an embodiment of the present application. As shown in Figures 19, 20 and 21, the sealing portion 332 includes a first sealing sub-portion 3321, a second sealing sub-portion 3322, a third sealing sub-portion 3323 and a fourth sealing sub-portion 3324 connected end to end, wherein the first sealing sub-portion 3321 and the third sealing sub-portion 3323 are arranged opposite to each other along the X-axis direction, the second sealing sub-portion 3322 and the fourth sealing sub-portion 3324 are arranged opposite to each other along the Z-axis direction, and along the Z-axis direction, the second sealing sub-portion 3322 is located on the side of the fourth sealing sub-portion 3324 away from the fourth division 94 of the first annular seal 90. A blocking structure 110 is provided in the two gaps surrounded by the annular support portion 331, the second side wall 8232, the fourth sealing sub-portion 3324 of the sealing portion 332 and the fourth division 94 of the first annular seal 90, that is, one of the surfaces of the blocking structure 110 is in contact with the fourth sealing sub-portion 3324 of the sealing portion 332, one of the surfaces is in contact with the second side wall 8232, and one of the surfaces is in contact with the fourth division 94 of the first annular seal 90, and the blocking structure 110 is overpressure set, that is, when the blocking structure 110 is in contact with the fourth sealing sub-portion 3324 of the sealing portion 332, the second side wall 8232 and the fourth division 94 of the first annular seal 90, there is no gap, and the blocking structure 110 can prevent the gas in the front cavity Q1 from being transmitted to the entire machine cavity through the gap, thereby further ensuring the sealing effect.

[0114] In this case, the width W2 of the blocking structure 110 in the X-axis direction is greater than or equal to 0.6 mm and less than or equal to 2 mm. This configuration ensures that the blocking structure 110 does not fail to provide a sealing effect due to its small width, nor does it occupy too much space in the entire device cavity due to its large width.

[0115] For example, the width W2 of the blocking structure 110 in the X-axis direction includes 0.6 mm, 0.8 mm, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm. The present embodiment does not limit the type of the blocking structure 110, and those skilled in the art may select the type based on actual circumstances. For example, the blocking structure 110 may be a dispensing glue or a soft glue.

[0116] In this case, referring to Figure 21, the blocking structure 110 and the annular sealing portion 332 are integrally formed. With this arrangement, when preparing the annular sealing portion 332, the blocking structure 110 is prepared, and there is no need to prepare the blocking structure 110 separately, which simplifies the process steps and reduces costs. It can also ensure that there is no gap between the blocking structure 110 and the annular sealing portion 332, thereby further ensuring the sealing effect.

[0117] In order to further enhance the sealing effect and prevent the air in the front cavity Q1 from being transmitted to the entire cavity through the gap between the blocking structure 110 and the fourth subdivision 94 of the first annular seal 90, see Figures 22 and 23. Figure 22 is a positional relationship diagram of the blocking structure, the second side wall, the fourth subdivision of the first annular seal, the sealing portion, and the auxiliary structure provided in an embodiment of the present application, and Figure 23 is an enlarged view of the UU area in Figure 22. As shown in Figures 22 and 23, an auxiliary structure 120 is provided at the area where the blocking structure 110 is connected to the fourth subdivision 94 of the first annular seal 90. The auxiliary structure 120 is used to shield the area where the blocking structure 110 is connected to the fourth subdivision 94 of the first annular seal 90, and the area where the blocking structure 110 is connected to the fourth subdivision 94 of the first annular seal 90 is sealed by the auxiliary structure 120.

[0118] The present embodiment does not limit the type of auxiliary structure 120 , and those skilled in the art may select the type based on practical circumstances. For example, the auxiliary structure 120 includes silicone or UV adhesive. For example, the auxiliary structure 120 may be formed by dispensing adhesive at the area where the barrier structure 110 connects to the fourth subsection 94 of the first annular seal 90 .

[0119] It should be noted that the above example is based on the example that the auxiliary structure 120 is located in the front cavity Q1, but it does not constitute a limitation of the present application. In other optional embodiments of the present application, refer to Figure 24, which is another positional relationship diagram of the blocking structure, the second side wall, the fourth division of the first annular seal, the sealing portion, and the auxiliary structure provided in the embodiment of the present application. As shown in Figure 24, an auxiliary structure 120 is provided in the area where the blocking structure 110 is connected to the fourth division 94 of the first annular seal 90, and the auxiliary structure 120 is located outside the front cavity Q1. When the auxiliary structure 120 is arranged on the outside of the front cavity Q1, it is beneficial to the arrangement of the auxiliary structure 120 and simplifies the process steps.

[0120] 21 , 22 , and 24 , when the blocking structure 110 is disposed within the two gaps defined by the annular support portion 331, the second sidewall 8232, the fourth sealing sub-portion 3324 of the sealing portion 332, and the fourth sub-portion 94 of the first annular seal 90, the blocking structure 110, the fourth sub-portion 94 of the first annular seal 90, the first sealing sub-portion 3321, the second sealing sub-portion 3322, the third sealing sub-portion 3323 of the sealing portion 332, the support portion 331, and the second sidewall 8232 can form a sealed cavity without the need for the fourth sealing sub-portion 3324. In other words, referring to FIG. 25 , FIG. 25 is another positional relationship diagram of the blocking structure, the second sidewall, the fourth sub-portion of the first annular seal, the sealing portion, and the auxiliary structure provided in an embodiment of the present application. The annular sealing portion 332 has an opening with two opposing ends, namely a first end 3325 and a second end 3326. One end of the blocking structure 110 in one of the gaps is connected to the first end 3325, while the other end contacts the fourth subsection 94 of the first annular seal 90. The other end of the blocking structure 110 in the other gap is connected to the second end 3325, while the other end contacts the fourth subsection 94 of the first annular seal 90. Exemplarily, the first, second, and third sealing subsections 3321, 3322, and 3323 sealing subsections form a U-shape with the two end points of the U contacting the fourth subsection 94 of the first annular seal 90 to complete the seal. This simplifies the structure of the sealing portion 332, conserves materials, and reduces costs.

[0121] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
