Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to an electronic device. Background Art

[0002] The speaker (SPK) component is a crucial component for sound playback in electronic devices like personal computers, tablets, mobile phones, and wearables. To ensure smooth transmission of sound from the SPK component to the outside of the electronic device, its placement within the device and the configuration of its corresponding audio channels are crucial factors influencing the sound playback and overall architecture of the device.

[0003] The SPK component can be placed in an electronic device in two ways: vertically and horizontally. The vertical placement of the SPK component is to set the thickness direction of the SPK component perpendicular to the thickness direction of the electronic device, and the sound channel is set on the middle frame. However, the width of the SPK component will affect the overall structure of the electronic device, resulting in a relatively large thickness of the entire device, which is not conducive to the design of thinning and weight reduction of the electronic device.

[0004] The SPK component is placed flat when its thickness direction is set in the same direction as the thickness direction of the electronic device, and the sound channel is set on the bottom shell. However, in the scenario where the electronic device motherboard is close to the bottom shell, a large gap will be set on the printed circuit board (PCB) to make the SPK component and the sound channel relative to each other, which is not conducive to the PCB layout area. In addition, on some wearable devices, the sound channel set on the bottom shell may be blocked by the user, which is not conducive to user application. Summary of the Invention

[0005] An embodiment of the present application provides an electronic device to solve the technical problem that the location of the SPK component in the electronic device affects the sound effect and increases the thickness of the electronic device.

[0006] An embodiment of the present application provides an electronic device, comprising: a middle frame assembly, the middle frame assembly including a sound outlet; a sound-emitting device, the sound-emitting device being located inside the electronic device and adjacent to the middle frame assembly; a sound outlet channel, the sound outlet channel being located inside the electronic device and being arranged on one side of the sound-emitting device along a first direction, the first direction being the thickness direction of the electronic device; the sound outlet side of the sound-emitting device facing the sound outlet channel, the sound outlet channel being connected to the sound outlet side and the sound outlet channel. The sound-emitting device can be arranged adjacent to the middle frame assembly, and the sound emitted by the sound-emitting device can be transmitted through the sound outlet channel and the sound outlet channel to be sent to the outside of the electronic device through the middle frame assembly, thereby effectively reducing the impact of the structural arrangement of the sound-emitting device on the overall thickness of the electronic device while ensuring the sound effect.

[0007] In a feasible embodiment, the middle frame assembly includes a middle frame side wall and an extension portion connected to each other; the sound hole is arranged on the middle frame side wall; the extension portion is located inside the electronic device, and the extension portion is arranged opposite to the sound output side of the sound-emitting device along a first direction and has a gap to form a sound output channel.

[0008] In one feasible embodiment, the side wall of the middle frame includes a middle frame exterior surface facing the exterior of the electronic device; an end of the sound outlet remote from the sound outlet channel extends to the middle frame exterior surface, connecting the sound outlet hole to the exterior of the electronic device; the sound outlet hole has a first inclination angle relative to a second direction, such that the end of the sound outlet hole remote from the sound outlet channel is located in the middle of the middle frame exterior surface along the first direction, and the second direction is perpendicular to the first direction. In this way, the outlet of the sound outlet hole on the middle frame exterior surface can be located in the middle, thereby improving the aesthetics of the electronic device and reducing obstruction of the sound outlet hole by the user during use.

[0009] In one feasible embodiment, the electronic device further includes a display screen and a bottom housing, the display screen and the bottom housing being disposed opposite each other along a first direction on opposite sides of the middle frame assembly; the sound-generating device is located between the display screen and the bottom housing, with the sound-emitting side of the sound-generating device facing the display screen, and the extension portion being located between the sound-generating device and the display screen. In this manner, the sound-generating device can be positioned toward the display screen, reducing the impact of the sound-generating device's structural arrangement on the structures of other electronic components within the electronic device. Furthermore, the arrangement of the sound-emitting channel and the sound-emitting hole allows the sound output of the electronic device to be located within the middle frame assembly, thereby improving the sound quality of the sound-generating device.

[0010] In one feasible embodiment, the electronic device further includes a display screen and a bottom housing, the display screen and the bottom housing being disposed opposite each other along a first direction on opposite sides of the middle frame assembly; the sound-generating device is located between the display screen and the bottom housing, with the sound-emitting side of the sound-generating device facing the bottom housing, and the extension portion being located between the sound-generating device and the bottom housing. This allows the heat source of the sound-generating device to be closer to the display screen, thereby reducing heat dissipation toward the bottom housing, preventing the large amount of heat generated by the sound-generating device from being dissipated through the bottom housing and affecting user experience, thereby improving the user experience.

[0011] In one feasible embodiment, the thickness of the sound-generating device is smaller than its width, and the thickness direction of the sound-generating device is arranged parallel to the first direction. In this way, the sound-generating device can be placed flat inside the electronic device, reducing the impact of the sound-generating device and its limiting structure on the thickness of the electronic device.

[0012] In one feasible embodiment, the thickness of the sound-emitting device is smaller than its width, and the thickness direction of the sound-emitting device has a second inclination angle relative to the first direction. This allows the sound-emitting device to be positioned at a smaller angle within the electronic device, thereby aligning the sound-emitting side more closely with the extension direction of the sound outlet, thereby improving the sound quality of the electronic device.

[0013] In one feasible embodiment, the sound outlet includes a transmission section and a sound outlet end, the transmission section and the sound outlet end being connected. The sound outlet end is disposed on the exterior surface of the middle frame, extending in the second direction and having a width greater than that of the transmission section, thereby forming a first step surface at the connection between the sound outlet end and the transmission section. This allows for modification of the structure of the sound outlet on the exterior surface of the middle frame, improving the aesthetics of the electronic device.

[0014] In one feasible embodiment, the electronic device further includes a decorative piece, which is disposed at the sound outlet and adjacent to the first stepped surface. In this way, the structure of the sound outlet on the exterior surface of the middle frame can be modified to improve the aesthetics of the electronic device.

[0015] In one feasible embodiment, the electronic device further includes a dust cover having an array of sound-permeable holes formed thereon, the dust cover being disposed at the sound outlet and adjacent to the first stepped surface. This can improve the appearance of the sound outlet while reducing dust from entering the electronic device through the sound outlet, thereby improving the operational stability of the electronic device.

[0016] In one feasible embodiment, the sound outlet includes a transmission section and a sound receiving end, the transmission section and the sound receiving end being connected; the sound receiving end is disposed on a side wall of the middle frame near the interior of the electronic device, and the width of the sound receiving end is greater than the width of the transmission section, thereby forming a second step surface at the connection between the sound receiving end and the transmission section; the electronic device also includes a first dustproof net assembly, the first dustproof net assembly being disposed at the sound receiving end, and the first dustproof net assembly being disposed adjacent to the second step surface. In this way, a dustproof structure can be provided between the sound outlet and the sound output channel, thereby achieving a dustproof function for the electronic device.

[0017] In one feasible embodiment, the first dustproof net assembly includes a first dustproof net and a first adhesive layer, and the first dustproof net is bonded to the second step surface via the first adhesive layer. In this way, the dustproof structure can be fixed to improve the dustproof effect of the electronic device.

[0018] In one feasible embodiment, the electronic device further includes a second dustproof net assembly, which is disposed on the sound-emitting side of the sound-emitting device. The second dustproof net assembly includes at least a second adhesive layer and a second dustproof net, which is disposed on the sound-emitting side of the sound-emitting device via the second adhesive layer. In this way, the dustproof structure can be fixed to the sound-emitting side, directly providing dustproofing for the sound-emitting device and improving the dustproofing effect of the electronic device.

[0019] In one feasible embodiment, the second dust screen assembly further includes a third adhesive layer and a fixing layer. The fixing layer is an annular sheet structure. The fixing layer is attached to the side of the second dust screen away from the sound-generating device via the third adhesive layer. This provides a secure fit for the dust screen, preventing loosening of the dust screen structure from affecting the sound quality of the sound-generating device.

[0020] In one feasible embodiment, the middle frame assembly further includes a retaining wall connected to the extension portion and extending along the first direction; the retaining wall is disposed adjacent to the sound-generating device. This enhances the middle frame assembly's ability to retain the sound-generating device and improves the installation stability of the sound-generating device.

[0021] In one feasible embodiment, an elastic protrusion is provided on the side of the sound-generating device adjacent to the sound-emitting side. The sound-generating device is interference-fitted with the side walls and retaining wall of the middle frame via the elastic protrusion. This can improve the waterproof performance of the electronic device by reducing the gap between them and prevent water from entering the electronic device.

[0022] In one feasible embodiment, the middle frame assembly further includes a support platform positioned between the sound-generating device and the extension portion, and connected to the extension portion or the side wall of the middle frame. A gap is provided between the support platform and the side wall of the middle frame to increase the height of the sound output channel in the first direction. This further limits the position of the sound-generating device, preventing it from shaking within the structure and affecting the operational stability of the electronic device. In some embodiments, the support platform and the sound-generating device can also work together to clamp the second dust screen assembly.

[0023] In one feasible embodiment, the electronic device further includes a circuit board, which is disposed on a side of the electronic device near the bottom housing; and the sound-generating device is disposed between the circuit board and the extension. This reduces the impact of the sound-generating device and the limiting structure on other electronic components within the electronic device, thereby facilitating the placement of other electronic components within the electronic device.

[0037] The technical solutions of the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application.

[0038] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more. Words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not limit them to be necessarily different.

[0039] It should be noted that, in this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0040] The following first describes the application scenarios of the embodiments of the present application with reference to the accompanying drawings.

[0041] Figure 1 This is a partial structural diagram of an electronic device with SPK components placed vertically. Figure 2A schematic diagram of the partial structure of an electronic device with a flat SPK component.

[0042] The speaker (SPK) component is a crucial component for sound playback in electronic devices like personal computers, tablets, mobile phones, and wearables. To ensure that the sound produced by the SPK component can be transmitted outside the electronic device, an audio channel must be provided on the electronic device housing surrounding the SPK component to disseminate the sound.

[0043] Take the wearable device of watch terminal as an example of the electronic device for setting SPK components. Figure 1 As shown, in some embodiments, the electronic device 100 includes a screen 110, a middle frame 120, a back cover 130, and an SPK assembly 140 disposed within the electronic device 100. The SPK assembly 140 can be placed vertically within the electronic device 100, with the sound output oriented toward the middle frame 120 of the electronic device 100. The two sides of the SPK assembly 140 along its length are positioned adjacent to the screen 110 and the bottom cover 120, respectively. A middle frame sound output channel 121 is provided on the middle frame 120 in the direction of the SPK assembly 140's sound output, thereby transmitting the sound emitted by the SPK assembly 140 to the outside of the electronic device 100.

[0044] At the same time, due to the size limitations of the electronic device 100 itself, in order to prevent the SPK assembly 140 from occupying the structural space of other electronic components within the device, the main body of the SPK assembly 140 may be a substantially rectangular parallelepiped structure, and the SPK assembly 140 may be provided with a protrusion. This application does not impose any restrictions on the specific structure of the SPK assembly 140. However, it should be understood that the length and width of the SPK assembly 140 are both greater than its thickness. When the SPK assembly 140 is placed vertically, the thickness direction of the SPK assembly 140 is perpendicular to the overall thickness direction of the electronic device 100. In this case, the width direction of the SPK assembly 140 is consistent with the thickness direction of the electronic device 100.

[0045] Therefore, when the SPK component 140 is placed vertically, the width of the SPK component 140 will affect the overall thickness of the electronic device 100. The overall thickness of the electronic device 100 will be greater than the sum of the width of the SPK component 140 and the thickness of the screen 110 and the back cover 130, making the electronic device 100 thicker, which is not conducive to the actual user experience.

[0046] like Figure 2 As shown, the SPK component 140 can also be placed flat inside the electronic device 100, wherein the sound output direction of the SPK component 140 is toward the direction of the rear shell 130. In order to transmit the sound emitted by the flat SPK component 140 to the outside of the electronic device 100, a bottom shell sound output channel 131 is provided on the rear shell 130. The bottom shell sound output channel 131 connects the sound output position of the SPK component 140 and the external environment, thereby allowing the sound to be transmitted.

[0047] However, when the sound channel 131 is located on the back cover 130 and the electronic device 100 is a wristwatch, the back cover 130 is close to the user's body and the sound channel 131 is easily blocked when the electronic device 100 is worn, thereby affecting the sound quality of the SPK assembly 140. Furthermore, since the SPK assembly 140 is located close to the back cover 130 when the electronic device 100 is placed flat, this can affect the structure and layout of the printed circuit board in the electronic device 100. Alternatively, a large gap may be required on the printed circuit board to accommodate the SPK assembly 140, which is detrimental to the layout area of the printed circuit board.

[0048] In order to solve the above problems, an electronic device is provided in an embodiment of the present application, which optimizes the setting position and method of the SPK component through structural setting, thereby solving the problem that the setting position of the SPK component affects the sound effect and increases the thickness of the electronic device.

[0049] Figure 3 is a schematic diagram of an electronic device in an embodiment of the present application, Figure 4 This is a schematic diagram of a partial structure of an electronic device in an embodiment of the present application. Figure 5 This is a structural diagram of a middle frame assembly in an embodiment of the present application.

[0050] like Figure 3 and Figure 4 As shown, the electronic device 300 in the embodiment of the present application includes at least a middle frame assembly 310, a sound-emitting device 320, and a sound outlet channel 330. A sound outlet hole 311 is provided on the middle frame assembly 310, and the sound-emitting device 320 is disposed inside the electronic device 300, adjacent to the middle frame assembly 310. The sound outlet channel 330 is also located inside the electronic device 300, and is disposed on one side of the sound-emitting device 320 along a first direction. The sound outlet side 321 of the sound-emitting device 320 faces the sound outlet channel 330, and the sound outlet channel 330 is connected to the sound outlet side 321 and the sound outlet hole 311, respectively. Therefore, the sound emitted by the sound-emitting device 320 is emitted through the sound outlet side 321 and successively passes through the sound outlet channel 330 and the sound outlet hole 311, and is transmitted outside the electronic device 300.

[0051] In the embodiment of the present application, the first direction is the thickness direction of the electronic device, that is, Figure 4 The Z direction is shown in Figure 4 The X direction shown in the figure may be the width direction of the electronic device, and the X direction is perpendicular to the Z direction.

[0052] It should be understood that Figure 4 And the subsequent cross-sectional structure for showing the sound device 320 are Figure 3 Middle AA section, and it should be noted that, Figure 3The AA section in FIG. 1 is a structure obtained by taking a section at a position where the sound outlet hole 311 is provided.

[0053] For example, in order to facilitate the arrangement of the position of the sound-emitting device 320 and reduce the layout position occupied by the sound-emitting device 320, the sound-emitting device 320 may be a rectangular columnar structure, and the length of the sound-emitting device 320 is greater than the width of the sound-emitting device 320, and the width of the sound-emitting device 320 is greater than the thickness of the sound-emitting device 320, so that the sound-emitting device 320 can be set in the electronic device 300.

[0054] It should be understood that the sound-generating device 320 in the embodiment of the present application may be the same speaker structure as the aforementioned SPK component 140 , and the present application does not impose any limitation on this.

[0055] To achieve the sound-producing function, one side of the sound-producing device 320 is the sound-emitting side 321, and the direction of the sound-emitting side 321 is the sound-emitting direction of the sound-producing device 320. To achieve a better sound-producing effect, the sound-emitting side 321 of the sound-producing device 320 should be the side with the largest surface area. Therefore, in this embodiment, the sound-emitting side 321 can be the side with the length and width of the entire sound-producing device 320 as its length and width, so that the sound-emitting side 321 has a larger surface area, which facilitates the sound-emitting side 321 to produce different sounds.

[0056] In the embodiment of the present application, the first direction refers to the thickness direction of the electronic device 300. Therefore, the sound output channel 330 is arranged in the thickness direction of the sound device 320 of the electronic device 300. This facilitates that when the sound device 320 is placed flat or nearly flat, the sound emitted by the sound output side 321 can be transmitted to the sound output channel 330, so that the sound emitted by the sound device 320 can be smoothly transmitted. It should be understood that the sound device 320 is placed flat when the thickness direction of the sound device 320 is the same as the thickness direction of the electronic device 300, and the sound device 320 is placed nearly flat when the thickness direction of the sound device 320 is at an angle to the thickness direction of the electronic device 300. In some embodiments, the angle is less than 18 degrees, so that the setting posture of the sound device 320 is close to flat.

[0057] In some embodiments, in order to enable the sound-emitting device 320 to be stably installed in the electronic device 300, a bracket (not shown in the figure) is provided between the electronic device 300 and the side of the sound-emitting device 320 opposite to the sound-emitting side 321 in the thickness direction, and the bracket can be connected to the middle frame assembly 310, thereby maintaining the posture of the sound-emitting device 320 and improving the installation stability of the sound-emitting device 320. In this embodiment, the bracket can be connected to the middle frame assembly 310 by a connection method such as a snap connection or a locking screw, thereby providing support and fixation for the sound-emitting device 320. It should be noted that the connection method of the bracket in the embodiment of the present application is only one feasible implementation method, and the present application can also use any other connection method to achieve the connection between the bracket and the middle frame assembly 310.

[0058] It should be noted that since the attenuation of sound in solids is relatively large, the sound outlet channel 330 and the sound outlet hole 311 are provided to transmit the sound emitted by the sound device 320 to the outside of the electronic device 300. The sound outlet channel 330 can be provided through the structure of the middle frame assembly 310, thereby forming a whole with the sound device 320. For example, Figure 4 As shown, the middle frame assembly 310 may include a middle frame side wall 312 and an extension portion 313 connected to each other, the sound hole 311 is arranged on the middle frame side wall 312, and the extension portion 313 is arranged inside the electronic device 300, and the extension portion 313 is arranged opposite to the sound output side 321 of the sound-emitting device 320 along a first direction, and there is a gap between the extension portion 313 and the sound output side 321, thereby forming a sound output channel 330.

[0059] In the embodiment of the present application, the middle frame side wall 312 is the main structure of the middle frame assembly 310, that is, the structure in the middle frame assembly 310 for supporting the side shape of the electronic device 300. The shape of the middle frame side wall 312 determines the specific shape and structure of the side of the electronic device 300.

[0060] For example, the side of the middle frame side wall 312 facing the external environment of the electronic device 300 includes a middle frame appearance surface 3121. The specific shape of the middle frame appearance surface 3121 will affect the appearance of the electronic device 300. Figure 4 As shown, the curved middle frame exterior surface 3121 ensures that the side of the middle frame sidewall 312 facing the outside of the electronic device 300 has the same curvature, which can improve the overall aesthetics of the electronic device 300. Furthermore, the curved middle frame sidewall 312 can increase the space within the electronic device 300, facilitating the layout of electronic components adjacent to the middle frame assembly 310.

[0061] The extension portion 313 is arranged opposite to the sound output side 321 along the first direction, so the extension portion 313 is also arranged in the thickness direction of the electronic device 300, so that when the sound-emitting device 320 emits sound through the sound output side 321, the sound is reflected to the sound output hole 311 through the extension portion 313 and propagated to the outside of the electronic device 300.

[0062] The sound outlet 311 can extend from the inside of the electronic device 300 to the outside of the electronic device 300, thereby connecting the sound outlet channel 330 to the external environment. Figure 4 As shown, by making the extension direction of the sound hole 311 have a first inclination angle relative to the second direction, the end of the sound hole 311 away from the sound outlet channel 330 is located in the middle of the middle frame appearance surface 3121 along the first direction, so that the opening position of the sound hole 311 on the middle frame appearance surface 3121 is located in the middle area, thereby improving the aesthetics of the electronic device 300 and reducing obstruction during user use. It should be understood that the width direction of the electronic device 300 is perpendicular to the thickness direction of the electronic device 300, and therefore the second direction is perpendicular to the first direction. In the embodiment of the present application, the middle portion of the middle frame appearance surface 3121 along the first direction is a region range, which includes the central position of the middle frame appearance surface 3121 along the first direction. At the same time, this region range has a certain size in the first direction. Therefore, the angle of the first inclination can be reduced without affecting the aesthetics of the middle frame appearance surface 3121, thereby preventing the sound hole 311 from tilting too much and affecting the sound output.

[0063] For example, the second direction may be Figure 4 The X direction is shown in FIG.

[0064] In the embodiment of the present application, in order to limit the sound device 320, the sound device 320 is arranged adjacent to the middle frame assembly 310, such as Figure 5 As shown, the middle frame assembly 310 may further include a retaining wall 314 and a support platform 315 , wherein the retaining wall 314 may be arranged around the sound-generating device 320 , and the extension portion 313 and the retaining wall 314 may be combined to form a cavity for accommodating the sound-generating device 320 .

[0065] The support platform 315 can be arranged on the side of the sound outlet 311 close to the inside of the electronic device 300, thereby providing support for the sound-emitting device 320 and preventing it from being misplaced or blocking the sound outlet 311. It should be understood that the structures of the aforementioned retaining wall 314 and support platform 315 are exemplary embodiments of the present application, and the specific structural arrangements of the retaining wall 314 and support platform 315 can be adjusted to certain extent according to the installation position and structure of the sound-emitting device 320.

[0066] Figure 6 Schematic diagram of the external structure of a sound outlet in an embodiment of the present application.

[0067] like Figure 6 As shown in (a), in some embodiments of the present application, the sound hole 311 can also be a plurality of circular through holes 311a. For example, the plurality of circular through holes 311a can be arranged in an array on the middle frame side wall 312 along the length direction of the sound-emitting device 320, thereby connecting to the sound outlet channel 330 to send the sound emitted by the sound-emitting device 320 to the outside of the electronic device 300.

[0068] like Figure 6 As shown in (b), the sound hole 311 can also be a plurality of waist-shaped holes 311b, wherein the waist-shaped holes 311b are strip-shaped holes with two round ends, and the length of the waist-shaped holes 311b can be less than or equal to the length of the sound-emitting device 320, so that the sound hole 311 can be connected to the sound outlet channel 330 to send the sound emitted by the sound-emitting device 320 to the outside of the electronic device 300.

[0069] In some embodiments, the diameter of the circular through hole 311a and the width of the waist-shaped hole 311b can be between 0.6 mm and 2 mm, thereby reducing the structural impact of the sound hole 311 on the middle frame side wall 312 while being able to transmit the sound sent by the sound device 320.

[0070] It should be noted that the shape and size of the aforementioned sound hole 311 are only a few possible implementations in this application. The specific shape and size of the sound hole 311 in this application can also be other values, and this application does not impose any restrictions on this. However, it should be understood that for the structural safety of the electronic device 300, the specific size of the sound hole 311 will be affected by the length and width of the middle frame assembly 310. For example, the length of the sound hole 311 needs to be less than the length of the side of the middle frame assembly 310 where the sound hole 311 is provided, and the width of the sound hole 311 needs to be less than the width of the middle frame assembly 310.

[0071] Figure 7 This is a structural schematic diagram of a sound outlet provided with a decorative piece in an embodiment of the present application.

[0072] pass Figure 6 It can be seen that when the extension direction of the sound hole 311 and the second direction have a first inclination angle, the inclination of the sound hole 311 will affect the overall appearance of the middle frame side wall 312. Figure 7 As shown, the overall appearance of the middle frame assembly 310 can be improved by providing a decorative member 340 on the side of the sound outlet 311 close to the middle frame appearance surface 3121.

[0073] Exemplarily, the sound outlet 311 includes a transmission section 3111 and a sound outlet end 3112. The transmission section 3111 is a hole in the sound outlet 311 extending in a direction having a first inclination angle with the second direction, and the transmission section 3111 is connected to the sound outlet end 3112. It should be understood that the sound outlet end 3112 is provided on the exterior surface 3121 of the middle frame. When the sound emitted by the sound-emitting device 320 enters the sound outlet 311, it first passes through the transmission section 3111 and is then transmitted to the outside of the electronic device 300 through the sound outlet end 3112.

[0074] In order to be able to modify the appearance of the sound hole 311 through the sound outlet end 3112, the extension direction of the sound outlet end 3112 is the same as the second direction, so that the outlet of the sound hole 311 is facing the side of the electronic device 300, beautifying the appearance of the middle frame assembly 310 while adjusting the angle of sound emission from the electronic device 300, thereby improving the user experience.

[0075] In some embodiments, to facilitate placement of the decorative member 340 at the sound outlet 3112, the width of the sound outlet 3112 may be greater than the width of the transmission section 3111, thereby forming a first stepped surface 3112a at the junction of the sound outlet 3112 and the transmission section 3111. It should be understood that to avoid obstructing the transmission section 3111, the first stepped surfaces 3112a are located on both sides of the junction of the sound outlet 3112 and the transmission section 3111 in the first direction, thereby enabling placement of the decorative member 340 or other components via the first stepped surfaces 3112a.

[0076] Taking the shape of the sound outlet 311 as a waist-shaped hole 311b as an example, the width of the waist-shaped hole 311b is the length of the waist-shaped hole 311b in the first direction. When the width of the sound outlet end 3112 is greater than the transmission section 3111, the first stepped surfaces 3112a are respectively provided on both sides of the sound outlet end 3112 in the first direction, forming two strip-shaped first stepped surfaces 3112a. In the embodiment of the present application, the widths of the two first stepped surfaces 3112a can be the same or different, and this application does not impose any limitation on this.

[0077] In some embodiments, the length of the sound outlet end 3112 may also be slightly larger than the length of the transmission section 3111, so that the first step surface 3112a forms an annular plane with an inner ring in the shape of the transmission section 3111 and an outer ring in the shape of the sound outlet end 3112, so as to facilitate the arrangement of the decorative part 340 or other components.

[0078] For example, Figure 7As shown, the electronic device 300 may further include a decorative member 340. The decorative member 340 may be disposed within the sound outlet 3112, adjacent to the first stepped surface 3112a. It should be understood that, in order to allow the sound emitted by the sound-emitting device 320 to be transmitted outside the electronic device 300 through the sound outlet 311, the decorative member 340 may also have a structure having a hole. For example, the decorative member 340 may be an annular structure with an inner ring shaped like the transmission section 3111 and an outer ring shaped like the sound outlet 3112, thereby allowing sound to be transmitted directly through the hole.

[0079] In some embodiments, the decorative member 340 can be mounted on the sound outlet 3112 by snapping onto the two side surfaces of the sound outlet 3112 located in the first direction. In other embodiments, the decorative member 340 can be bonded to the first stepped surface 3112a via an adhesive layer, thereby being mounted on the sound outlet 3112. The above-described methods of mounting the decorative member 340 on the sound outlet 3112 are merely two implementations of the present application, and the present application does not limit the manner in which the decorative member 340 is mounted on the sound outlet 3112.

[0080] Figure 8 This is a schematic diagram of the structure of an electronic device in an embodiment of the present application. Figure 9 This is a schematic structural diagram of another electronic device in an embodiment of the present application.

[0081] like Figure 8 and Figure 9 As shown, in order to realize the functions of the electronic device 300 and protect the overall structure of the electronic device 300, the electronic device 300 may also include a display screen 350 and a bottom shell 360. The display screen 350 and the bottom shell 360 may be relatively arranged on both sides of the middle frame assembly 310 along a first direction. The display screen 350, the middle frame assembly 310 and the bottom shell 360 together enclose the appearance structure of the electronic device 300.

[0082] In the embodiment of the present application, since the sound emitted by the sound device 320 is transmitted to the outside of the electronic device 300 through the sound outlet channel 330 and the sound outlet hole 311, the sound device 320 can be set toward the display screen 350 or toward the bottom shell 360. Figure 8 As shown, the sound-generating device 320 is located between the display screen 350 and the bottom shell 360, the sound-emitting side 321 of the sound-generating device 320 faces the display screen 350, the extension part 313 is located between the sound-generating device 320 and the display screen 350, and the gap between the extension part 313 and the sound-generating device 320 is the sound-emitting channel 330.

[0083] In this embodiment, the sound-emitting side 321 of the sound-emitting device 320 is arranged toward the display screen 350. The sound-emitting device 320 placed flat or nearly flat can effectively reduce the overall thickness of the electronic device 300. At the same time, the sound is sent to the outside through the sound outlet 311 set on the middle frame assembly 310 through the sound outlet channel 330, reducing the user's obstruction of the sound outlet 311 and optimizing the sound effect of the sound-emitting device 320.

[0084] It should be noted that in order to set the sound-emitting device 320 at an adjacent position of the middle frame assembly 310, an adhesive layer can be provided at the contact position of the sound-emitting device 320 and the middle frame assembly 310 to fix the two together. The sound-emitting device 320 can also be clamped to the middle frame assembly 310 by providing a clamping part on the middle frame assembly 310. The bracket can also be connected to the middle frame assembly 310 by clamping or locking screws, so that the bracket can be used to limit the sound-emitting device 320, thereby fixing the sound-emitting device 320 and the middle frame assembly 310 together.

[0085] like Figure 5 and Figure 8 As shown, the middle frame assembly 310 may also include a retaining wall 314, which is connected to the extension portion 313, and the retaining wall 314 may extend along the first direction or the thickness direction of the sound-emitting device 320. At the same time, the retaining wall 314 is arranged adjacent to the sound-emitting device 320, so that the sound-emitting device 320 is limited by the retaining wall 314.

[0086] In some embodiments, the retaining wall 314 may extend toward the bottom housing 360, or may extend toward the display screen 350. The extending direction of the retaining wall 314 is related to the orientation of the sound generating device 320. Figure 8 As shown, when the sound output side 321 faces the display screen 350 , the retaining wall 314 may extend toward the bottom housing 360 .

[0087] For example, since the thickness of the sound-emitting device 320 is smaller than the width of the sound-emitting device 320 , when the sound-emitting device 320 is placed flat, that is, the thickness direction of the sound-emitting device 320 is consistent with the thickness direction of the electronic device 300 , the overall thickness of the electronic device 300 can be effectively reduced, thereby achieving thinning of the electronic device 300 .

[0088] In some embodiments, because the sound-emitting device 320 is tilted at a relatively small angle, for example, when the tilt angle in the thickness direction of the sound-emitting device 320 is less than 18°, the sound-emitting side 321 can be oriented closer to the sound-emitting hole 311, thereby facilitating the transmission of the sound emitted by the sound-emitting device 320. Furthermore, when tilted at a relatively small angle, since the sound-emitting device 320 has a protrusion, tilting at a relatively small angle can also reduce the size of the sound-emitting device 320 in the first direction in actual applications, making the size of the sound-emitting device 320 in the first direction smaller than the width of the sound-emitting device 320. Therefore, such an arrangement of the sound-emitting device 320 can reduce the thickness of the electronic device 300. It should be noted that the tilt angle in the thickness direction of the sound-emitting device 320 is the angle relative to the thickness direction of the electronic device 300.

[0089] like Figure 8 As shown in (a) and (b), in some embodiments of the present application, the sound-emitting device 320 is tilted, the first direction is the direction a in the figure, and the thickness direction of the sound-emitting device 320 is the direction b in the figure. When tilted, the thickness direction of the sound-emitting device 320 has a second tilt angle relative to the first direction, and the tilt direction of the sound-emitting device 320 is toward the sound outlet 311, shortening the distance between the sound outlet side 321 and the sound outlet 311, thereby improving the sound transmission efficiency. It should be understood that the second tilt angle is Figure 8 As shown in (a), the included angle between the direction a and the direction b is 8° in this embodiment.

[0090] Because the sound-emitting device 320 is tilted and the extension portion 313 extends in the same direction as the second direction, when the sound-emitting device 320 is tilted, the gap between the extension portion 313 and the sound-emitting side 321 gradually increases along the second direction from the interior to the exterior of the electronic device 300. Therefore, when the sound-emitting device 320 is tilted, the sound-emitting channel 330 gradually increases from the interior to the exterior of the electronic device 300, making it easier for the sound emitted by the sound-emitting device 320 to be transmitted from the interior of the electronic device 300.

[0091] For example, the specific value of the second inclination angle may be between 0° and 18°, so that when tilted, the scale of the sound-emitting device 320 in the thickness direction of the electronic device 300 changes less, thereby improving the sound transmission efficiency and reducing the impact of the sound-emitting device 320 on the thickness of the electronic device 300.

[0092] It should be understood that in some embodiments of the present application, the width of the sound hole 311 at one end of the middle frame side wall 312 close to the sound outlet channel 330 and the width of the sound hole 311 at one end of the middle frame exterior surface 3121 may be different. The width of the sound hole 311 at one end of the middle frame side wall 312 close to the sound outlet channel 330 may be greater than the width of the sound hole 311 at one end of the middle frame exterior surface 3121, so that the width of the sound hole 311 gradually decreases from the inside to the outside of the electronic device 300, thereby achieving the purpose of an aesthetically pleasing setting.

[0093] In this embodiment of the present application, the width of the sound hole 311 indicates the size of the sound hole 311 in the first direction. The width of the sound hole 311 at one end located on the outer surface 3121 of the middle frame can range from 0.6 mm to 2 mm, thereby enhancing the aesthetics of the structure while still allowing sound to be transmitted.

[0094] It should be noted that the aforementioned width range of the sound outlet hole 311 is only a feasible implementation in this application, and this application does not limit the width range of the sound outlet hole 311.

[0095] like Figure 8 As shown in (c) and (d), in some embodiments of the present application, the sound-emitting device 320 can also be placed flat so that the thickness direction of the sound-emitting device 320 is the same as the first direction, so as to reduce the space occupied by the sound-emitting device 320 in the thickness direction of the electronic device 300. At this time, the sound output direction of the sound-emitting device 320 is perpendicular to the extension portion 313.

[0096] In some embodiments of the present application, in order to improve the installation stability of the sound-generating device 320, an elastic protrusion 322 may be provided on the sound-generating device 320, thereby reducing the gap between the sound-generating device 320 and the middle frame side wall 312 and the retaining wall 314, thereby improving the waterproof performance of the electronic device 300.

[0097] like Figure 8 As shown in (a), a plurality of elastic protrusions 322 can be provided on the side surface of the sound-generating device 320 adjacent to the sound-emitting side 321. The sound-generating device 320 is interference-fitted with the middle frame side wall 312 and the retaining wall 314 through the elastic protrusions 322, thereby setting the sound-generating device 320 adjacent to the middle frame assembly 310 and limiting it through the middle frame side wall 312 and the retaining wall 314.

[0098] The elastic protrusion 322 has a certain deformation function. During actual installation, the elastic protrusion 322 on the sound-generating device 320 will be close to the middle frame side wall 312 and the retaining wall 314, blocking the gap between the sound-generating device 320 and the middle frame side wall 312 and the retaining wall 314, thereby reducing the gap around the sound-generating device 320 leading to the electronic device 300, thereby achieving a waterproof effect.

[0099] It should be understood that Figure 8 The elastic protrusion 322 shown in (a) is merely an example in this application. The elastic protrusion 322 may be a strip-shaped protrusion structure, and this application does not limit the specific shape of the elastic protrusion 322. However, it should be noted that the height of the elastic protrusion 322 protruding from the side of the sound-generating device 320 is slightly greater than the gap between the sound-generating device 320 and the middle frame side wall 312 and the retaining wall 314, thereby achieving an interference fit. If the protrusion 322 is too high, the sound-generating device 320 will not be able to be placed between the middle frame side wall 312 and the retaining wall 314.

[0100] At the same time, in some embodiments, the elastic protrusion 322 can also be set on the retaining wall 314 and / or the middle frame side wall 312, so that when the sound-emitting device 320 is set between the middle frame side wall 312 and the retaining wall 314, the gap between the middle frame side wall 312 and the retaining wall 314 and the sound-emitting device 320 is reduced, thereby improving the waterproof performance of the electronic device 300.

[0101] Furthermore, the elastic protrusion 322 can also be set as follows Figure 8 In the scenario shown in (c) or (d) where the sound-generating device 320 is placed flat, the gap between the sound-generating device 320 and the middle frame side wall 312 and the retaining wall 314 is reduced, which is not described in detail in this application.

[0102] In some embodiments, Figure 5 as well as Figure 8 As shown in (b) and (d), in order to better arrange the sound-emitting device 320 adjacent to the middle frame assembly 310, the middle frame assembly 310 may further include a support platform 315, which is arranged between the sound-emitting device 320 and the extension portion 313, and the support platform 315 is connected to the extension portion 313 or the middle frame side wall 312, thereby forming a structure in contact with the sound-emitting device 320.

[0103] It should be understood that the function of the support platform 315 is to fix the sound-emitting device 320 and to cooperate with the sound-emitting device 320 to fix the dust screen set on the sound-emitting side 321, thereby clamping the dust screen to prevent it from falling off. In order to play the role of fixing and clamping, the support platform 315 needs to have a certain thickness. Therefore, the support platform 315 will reduce the width of the sound-emitting channel 330 or increase the overall thickness of the electronic device 300. Therefore, in actual application, Figure 5 As shown, a gap is provided between the support platform 315 connected to the middle frame side wall 312, thereby reducing the obstruction of the support platform 315 to the sound outlet channel 330 and the sound outlet hole 311, and increasing the height of the sound outlet channel 330 at the connection position with the sound outlet hole 311 in the first direction.

[0104] In addition, in order to realize other functions, the electronic device 300 needs to be provided with other electronic components, for example, Figure 8As shown in (a), the electronic device 300 may further include a circuit board 370, and the circuit board 370 is disposed on a side of the electronic device 300 near the bottom housing 360. The circuit board 370 can provide a mounting and structural function for the electronic device 300. To improve space utilization within the electronic device 300 and avoid reducing the area of the circuit board 370 to provide a mounting location for the sound device 320, the circuit board 370 can be disposed on a side near the bottom housing 360, and the sound device 320 can be disposed between the circuit board 370 and the extension 313, thereby achieving a layout of the circuit board 370. This structural arrangement can avoid reducing the layout area of the circuit board 370 and improve space utilization within the electronic device 300.

[0105] like Figure 9 As shown, when the sound-emitting device 320 in the electronic device 300 is set, the sound-emitting device 320 is located between the display screen 350 and the bottom shell 360, and the sound-emitting side 321 of the sound-emitting device 320 faces the bottom shell 360, the extension part 313 is located between the sound-emitting device 320 and the bottom shell 360, and the gap between the extension part 313 and the sound-emitting device 320 is the sound-emitting channel 330.

[0106] In this embodiment, the sound-emitting side 321 of the sound-emitting device 320 is arranged toward the bottom shell 360. The sound-emitting device 320 placed flat or nearly flat can effectively reduce the overall thickness of the electronic device 300. At the same time, the sound is sent to the outside through the sound outlet 311 set on the middle frame assembly 310 through the sound outlet channel 330, reducing the user's obstruction of the sound outlet 311 and optimizing the sound effect of the sound-emitting device 320.

[0107] It should be understood that the side of the sound-generating device 320 opposite the sound-emitting side 321 is the primary heat source for the sound-generating device 320. By aligning the sound-emitting side 321 with the bottom housing 360, the heat dissipation location of the sound-generating device 320 can be moved away from the bottom housing 350. Therefore, aligning the sound-emitting side 321 with the bottom housing 360 also reduces the amount of heat transferred to the user through the bottom housing 360 during operation of the sound-generating device 320, thereby improving the user's thermal experience.

[0108] It should be noted that since the electronic device 300 is typically positioned with the display screen 350 facing the user during use, the side where the display screen 350 is located can be defined as the upper side of the electronic device 300, and the side where the bottom housing 360 is located can be defined as the lower side of the electronic device 300. When the sound-emitting side 321 is positioned toward the bottom housing 360, the extension portion 313 and the middle frame sidewall 312 need to provide more stable support for the sound-emitting device 320 to prevent instability in the inverted position of the sound-emitting device 320.

[0109] For example, Figure 9As shown, in order to achieve better support and limiting effects, the middle frame assembly 310 may further include the retaining wall 314 in the aforementioned embodiment, the retaining wall 314 is connected to the extension portion 313, and the retaining wall 314 extends in the direction close to the display screen 350, thereby providing a limiting function for the sound device 320 disposed near the display screen 350. Figure 9 As shown in (a) and (b), the sound-generating device 320 is tilted at a certain angle. The thickness direction of the sound-generating device 320 has a second tilt angle relative to the first direction, thereby making the sound-generating device 320 tilted. The tilt direction of the sound-generating device 320 is toward the sound outlet 311, shortening the distance between the sound outlet side 321 and the sound outlet 311. For example, the specific value of the second tilt angle can be 8°.

[0110] like Figure 9 As shown in (c) and (d), in some embodiments of the present application, the sound device 320 can be placed flat, so that the thickness direction of the sound device 320 is aligned with the first direction, thereby reducing the space occupied by the sound device 320 in the thickness direction of the electronic device 300. In this case, the sound output direction of the sound device 320 is perpendicular to the extension portion 313. This can result in a structure that occupies less space in the thickness direction, thereby reducing the thickness of the electronic device 300 and achieving structural optimization of the electronic device 300.

[0111] Therefore, when the sound-emitting side 321 of the sound-emitting device 320 is positioned toward the bottom housing 360, the thickness direction of the sound-emitting device 320 can be aligned with the actual thickness direction of the electronic device 300, or the sound-emitting device 320 can be tilted at a certain angle. Specifically, the structures of the sound-emitting device 320 placed flat and tilted at a certain angle are the same as those described above when the sound-emitting side 321 is positioned toward the display screen 350. Furthermore, the structure used to limit the position and reduce the thickness of the electronic device 300 when the sound-emitting side 321 is positioned toward the bottom housing 360 is the same as that described above when the sound-emitting side 321 is positioned toward the display screen 350, and this application will not elaborate on these details.

[0112] Figure 10 This is a structural schematic diagram of a sound outlet provided with a dust cover in an embodiment of the present application.

[0113] In some embodiments of the present application, since the sound outlet 311 connects the inside and outside of the electronic device 300, there may be dust and other objects in the external environment that may affect the electronic components inside the electronic device 300. Therefore, in order to reduce the influence of factors such as dust in the external environment of the electronic device 300, such as Figure 10 As shown, the electronic device 300 may further include a dust cover 341 , which is disposed on the sound output end 3112 , and the dust cover 341 is disposed adjacent to the first step surface 3112 a .

[0114] In this embodiment of the present application, a plurality of sound-transmitting holes 3411 are arranged in an array on the dust cover 341, so that the sound generated by the sound-emitting device 320 is transmitted to the outside of the electronic device 300 through the sound-transmitting holes 3411. Furthermore, to improve the appearance of the electronic device 300, the dust cover 341 can be made of the same material as the middle frame assembly 310.

[0115] It should be understood that, similar to the way the decorative piece 340 is positioned at the sound outlet 3112, the dust cover 341 can also be secured to the sound outlet 3112 by bonding to the first stepped surface 3112a or by snapping onto both sides of the sound outlet 3112 in the first direction. In some embodiments, only one of the dust cover 341 and the decorative piece 340 can be positioned at the sound outlet 3112. For example, the dust cover 341 can be positioned at the sound outlet 3112 as a special decorative piece 340.

[0116] Figure 11 This is a structural schematic diagram of an electronic device provided with a first dustproof net assembly in an embodiment of the present application.

[0117] Furthermore, a dustproof structure can be provided on the side of the sound outlet 311 close to the sound outlet channel 330 to achieve a dustproof effect. Figure 11 As shown in (a), the sound outlet 311 may further include a transmission section 3111 and a sound receiving end 3113 . The transmission section 3111 and the sound receiving end 3113 are connected, and the sound receiving end 3113 is in communication with the sound outlet channel 330 .

[0118] Specifically, the sound receiving end 3113 is disposed on a side of the middle frame sidewall 312 close to the interior of the electronic device 300. The width of the sound receiving end 3113 is greater than the width of the transmission section 3111, thereby forming a second stepped surface 3113a at the connection between the sound receiving end 3111 and the transmission section 3113. The second stepped surface 3113a can be used to provide a dustproof structure at the connection between the sound output channel 330 and the sound output hole 311.

[0119] For example, the electronic device 300 may further include a first dustproof net assembly 380, which is disposed at the sound receiving end 3113 and adjacent to the second stepped surface 3113a, such that the first dustproof net assembly 380 is disposed at the connection between the sound output channel 330 and the sound output hole 311. In this manner, the first dustproof net assembly 380 can provide dust protection for the sound-emitting device 320.

[0120] In some examples of this application, Figure 11As described in (a) and (b), the first dustproof net assembly 380 may include a first dustproof net 381 and a first adhesive layer 382. The first dustproof net 381 is bonded to the second step surface 3113a through the first adhesive layer 382, thereby setting the first dustproof net 381 at the connection position between the sound outlet channel 330 and the sound outlet hole 311.

[0121] In some embodiments, the first dustproof net 381 includes a flexible dustproof net and a hard dustproof net that wraps around the flexible dustproof net. The flexible dustproof net can be made of nylon or other flexible materials, while the hard dustproof net can be made of metal. The hard dustproof net has larger holes and can support the flexible dustproof net, maintaining its shape and preventing the first dustproof net 381 from losing its support. For example, the hard dustproof net can have an L-shaped structure, with a portion of the hard dustproof net bonded to the second step surface 3113a and another portion bonded to the extension portion 313. This fixation to the extension portion 313 improves the securement of the flexible dustproof net.

[0122] It should be noted that the structural setting of the first dustproof net 381 is only a feasible implementation method in this application, and the structure and setting method of the first dustproof net 381 are not limited in this application.

[0123] like Figure 11 As shown in (b), the cross-sectional structure of the connection position between the sound outlet channel 330 and the sound outlet hole 311 is obtained by taking the position of the display screen 350 away from the bottom shell 360 as the top view. In some embodiments, due to the long length of the sound outlet hole 3111, a fixing block 3113b can be provided in the middle of the sound receiving end 3113. The fixing block 3113b protrudes from the surface of the sound receiving end 3113, and one side surface of the fixing block 3113b is provided adjacent to the first dustproof net assembly 380. For example, one side of the fixing block 3113b can be bonded to the first dustproof net 381 via a first adhesive layer 382, thereby achieving the purpose of reinforcing the first dustproof net assembly 380.

[0124] Figure 12 This is a structural diagram of an electronic device provided with a second dustproof net assembly in an embodiment of the present application. Figure 13 In the embodiment of this application Figure 12 A partial enlarged schematic diagram of area B in the middle.

[0125] In some embodiments of the present application, since the dustproof structure is mainly used to protect the sound-generating device 320 connected to the sound output channel 330, the dustproof structure can also be directly arranged between the sound-generating device 320 and the sound output channel.

[0126] like Figure 12 and Figure 13As shown, in some embodiments of the present application, the electronic device 300 may include a second dustproof net assembly 390, which is arranged on the sound output side 321 of the sound-emitting device 320, and the second dustproof net assembly 390 includes at least a second adhesive layer 391 and a second dustproof net 392, and the second dustproof net 392 is arranged on the sound output side 321 of the sound-emitting device 320 through the second adhesive layer 391.

[0127] The second dustproof net 392, a mesh structure with an area greater than or equal to the area of the sound-emitting side 321, is used to prevent dust from outside the electronic device 300 from entering the sound-emitting device 320 and affecting its sound output. The second adhesive layer 391 is an annular sheet structure, positioned between the sound-emitting side 321 and the second dustproof net 392, securing the second dustproof net 392 to the sound-emitting side 321 without affecting the sound output of the sound-emitting side 321.

[0128] In some embodiments, the support platform 315 may not be disposed entirely around the sound generating device 320. Figure 13 As shown, to reduce the risk of the second adhesive layer 391 peeling or wrinkling during extended use of the second dust screen 392, in some embodiments, the second dust screen assembly 390 may further include a third adhesive layer 393 and a fixing layer 394. The fixing layer 394 is an annular sheet structure or a sheet structure with hollows. The fixing layer 394 is disposed on the side of the second dust screen 392 away from the sound-generating device 320 via the third adhesive layer 393. It should be understood that the shape and structure of the fixing layer 394 and the third adhesive layer 393 are merely illustrative in the embodiments of this application. In actual applications, other structures that do not affect the sound output of the sound-generating device 320 may be used, and this application does not elaborate on them here.

[0129] The third adhesive layer 393 and the second adhesive layer 392 can be made of any material that is sticky and can be used to bond the electronic device 300 . The materials used for the third adhesive layer 393 and the second adhesive layer 392 can be the same or different, and this application does not impose any limitation on this.

[0130] In some embodiments, the fixing layer 394 may be a metal sheet, thereby supporting and fixing the second dustproof net 392 through the high rigidity of the metal sheet. Furthermore, in actual application, in order to enhance the installation stability of the extension portion 313 and the sound-generating device 320, a fourth adhesive layer 395 is provided on the side of the fixing layer 394 away from the second dustproof net 392, thereby bonding the fixing layer 394 to the extension portion 313 through the fourth adhesive layer 395 to improve the installation stability of the sound-generating device 320. It should be noted that the above structural stacking of the second dustproof net assembly 390 is only an optional specific solution. Removing part of the adhesive layer or adjusting the positional relationship between the second dustproof net 392 and the fixing layer 394 still falls within the scope of protection of this patent.

[0131] It should be noted that those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and practicing the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only, and the true scope of this application is indicated by the following claims.

[0132] It should be understood that the present application is not limited to the exact structures described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present application is limited only by the appended claims.
