The black matrix area is located between the display area of the display screen and the frame of the electronic device. The black matrix area can block some internal structures of the electronic device to improve the aesthetics of the exterior of the electronic device.
[0003] For example, some electronic devices are provided with a sound channel, and the black border area of the display screen can block the sound channel. In the prior art, in order to block the sound channel, the width of the black border area is relatively wide, thereby reducing the screen-to-body ratio of the electronic device (the ratio of the display area of the display screen to the total front area of the electronic device). Summary of the invention

[0019] In a possible implementation of the first aspect, a second sound outlet is provided on the first sub-segment, and a sound cavity is connected to the second sound outlet to form a second sound outlet channel.
[0020] According to the implementation of the present application, the second sound outlet can be provided on the side wall of the electronic device, and the width of the first sound outlet is set to be narrower in order to reduce the black border area of the display screen of the electronic device. Therefore, the second sound outlet can be provided to improve the sound effect of the electronic device.

Along the width, the size of the first seal is 30mm to 40mm. For example, in an embodiment of the present application, the size of the first seal along the width direction of the electronic device is 35mm. It should be understood that the size of the first seal needs to surround the first area, that is, the size of the first seal along the width direction of the electronic device needs to be greater than the width of the first sound outlet.

[0048] The specific implementation of the present application will be described in detail below with reference to the accompanying drawings.
[0049] The present application provides an electronic device, which can reduce the width of the black border area of the electronic device by reasonably setting the structure of the sound output channel, thereby increasing the screen-to-body ratio of the electronic device.
[0050] Exemplarily, the following uses a mobile phone as an example to introduce the electronic device in the embodiment of the present application. In other embodiments, the electronic device may also be a laptop computer, a tablet, a large-screen device, a wearable device (e.g., a watch, smart glasses, a helmet), an augmented reality (AR) / virtual reality (VR) device, a personal digital assistant (PDA), and other electronic devices with display functions, which are not limited in the present application.
[0051] The specific implementation of the present application will be described in detail below with reference to the accompanying drawings.
[0052] Figure 1A and Figure 1B An exemplary structural diagram of an electronic device 00 provided in an embodiment of the present application is shown. Figure 1A is a front view of the electronic device 00, Figure 1B is a cross-sectional view of the electronic device 00 ( Figure 1A AA cross-section diagram).
[0053] In the various figures herein, the X direction is the length direction of the electronic device 00, the Y direction is the width direction of the electronic device 00, and the Z direction (as the first direction) is the thickness direction of the electronic device 00. The X direction, the Y direction, and the Z direction are perpendicular to each other. Exemplarily, when the electronic device 00 is in a portrait state, the X direction is substantially parallel to the vertical direction; when the electronic device 00 is in a landscape state, the X direction is substantially parallel to the horizontal direction.
[0054] refer to Figure 1A and Figure 1B The electronic device 00 includes a display screen 100 and a housing 200, and the display screen 100 is covered on the housing 200. In this embodiment, the housing 200 includes a middle frame 21 (as a first housing) and a back cover 22 (or a "battery cover", as a second housing), and the middle frame 21 includes a panel 210 and a side wall 220 surrounding the panel 210 along the circumference of the panel 210, and the side wall 220 can form a frame of the electronic device 00. Along the Z direction, the display screen 100 and the back cover 22 are respectively located on opposite sides of the middle frame 21. Specifically, the display screen 100 is covered on the front side of the middle frame 21 along the Z direction, and the back cover 22 is covered on the back side of the middle frame 21 along the Z direction.
[0055] In addition, the side wall 220 and the panel 210 can enclose the inner cavity of the electronic device, and the inner cavity can include a front cavity 230 (as a cavity) and a rear cavity 20a, wherein the front cavity 230 is located on the side of the middle frame 21 facing the display screen 100, and the rear cavity 20a is located on the side of the middle frame 21 facing the back cover 22. Various functional components of the electronic device 00 (not shown in the figure) can be set in the front cavity 230 and the rear cavity 20a. For example, components such as a battery, a communication module, a mainboard, a camera module 23, and a speaker module 24 can be set in the rear cavity 20a.
[0056] In this embodiment, the middle frame 21 and the back cover 22 are independent structures, that is, the two can be made separately and then assembled. In this embodiment, the shell structure can be called a two-piece structure. In other embodiments, the middle frame 21 and the back cover 22 can be an integrated structure. In this embodiment, the shell structure can be called a unibody structure.
[0057] The electronic device 00 can realize its display function through the display screen 100, for example, displaying the boot screen, unlocking interface, application interface, etc. In some embodiments, the display screen 100 of the electronic device 00 also has a touch function, that is, the user can input data, instructions, etc. by touching the display screen 100.
[0058] refer to Figure 1A, the display screen 100 includes a display area 100a and a black border area 100b surrounding the display area 100a. Among them, the display area 100a is the area where the display screen 100 of the electronic device 00 displays images or the area that can be touched and operated by the user. The black border area 100b is the area between the side wall 220 of the middle frame 21 of the electronic device 00 and the display area 100a of the display screen 100 of the electronic device 00. The black border area 100b can be a light-proof structure, so that some internal structures of the electronic device 00 can be shielded. For example, after the display screen 100 is powered on, the light leaking between the display screen 100 and the frame of the electronic device 00 can be shielded, or structures such as the sound outlet channel inside the electronic device 00 can be shielded.
[0059] The display screen 100 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, etc., which is not limited in this embodiment.
[0060] In order to enable electronic devices to produce sound, some electronic devices are also provided with sound output channels. FIG. 2A to FIG. 2D The figure shows the configuration of the sound output channel of the electronic device 00' in some embodiments. Figure 2A It is a front view of the electronic device 00'. Figure 2B is a cross-sectional view of an electronic device 00' ( Figure 2A AA cross-section diagram). Figure 2C for Figure 2B Schematic diagram of the structure of part B. Figure 2D It is a top view of the middle frame 21 of the electronic device 00 ′.
[0061] refer to FIG. 2A to FIG. 2D , a sound outlet 30' is provided on the top of the electronic device 00'. The middle frame 21' of the electronic device includes a panel 210' and a side wall 220'. A channel 21a' is provided on the panel 210', and a channel 21b' is provided on the side wall 220'. The channel 21a', the channel 21b' and the sound outlet 30' are connected in sequence to form a sound outlet channel 40'. In addition, the channel 21a' is connected to a sound-emitting device 24' (for example, a speaker) provided in the rear cavity 20a' of the electronic device 0', so that the sound emitted by the sound-emitting device 24' can be transmitted to the outside of the electronic device 0' through the sound outlet channel 40.
[0062] The display screen 100' comprises a cover plate 110' and a display module 120' which are stacked in the Z direction (as the first direction). The cover plate 110' is covered on the side wall 220' in the Z direction so that the display screen 100' is connected to the housing 200'. Figure 2B and Figure 2C , the size of the black border area 100b' of the display screen 100' (i.e., the size from the edge of the display area 100a of the display screen 100' to the edge of the cover glass (CG) of the display screen 100) needs to include the following parts:
[0063] (1) d1, i.e., the width of the cover plate 110' of the display screen 100' covering the side wall 220' (the width of the glue dispensing area). When the cover plate 110' is covered on the side wall 220', the cover plate 110' and the side wall 220' need to be attached together by step glue. Since the size of the needle of the glue dispensing equipment for adding the step glue shall not be less than 0.55 mm, the width d1 of the glue dispensing area is at least 0.55 mm.
[0064] (2) d2, i.e., the wall thickness of the channel 21b'. Since the middle frame is usually formed by injection molding, considering the structural strength of the channel wall of the channel 21b' and the minimum wall thickness required by the injection molding process, the wall thickness of the channel 2b' is at least 0.4 mm.
[0065] (3) d3, that is, the clearance distance between the display module 120' and the side wall 220'. To ensure that the display module 120' does not interfere with the side wall 220', after the display module 120' is installed in the front cavity 230', the clearance distance between the display module 120' and the side wall 220' is at least 0.4 mm.
[0066] (4) d4, ie, the edge area of the display module 120' body. The edge area of the display module 120' body is the non-display part of the display module 120' and can be used for packaging, wiring, etc. The width of this area is at least 1 mm.
[0067] Therefore, at the position corresponding to the sound outlet channel 40', the size of the black border area 100b' of the display screen 100' is at least d1+d2+d3+d4=2.35mm. In addition, the size d5 from the CG edge of the display screen 100' to the edge of the electronic device 00' is usually 1.75mm, so the size from the edge of the display area AA of the display screen 100' to the edge of the electronic device 00' reaches d1+d2+d3+d4+d5=4.1mm. This results in a low screen-to-body ratio of the electronic device 00'.
[0068] Furthermore, at positions other than the position corresponding to the sound outlet channel 40', the black border area 100b' of the display screen 100' does not need to cover the channel wall of the channel 21b' (i.e., the size of the black border area 100b' does not need to include d2), resulting in the black border area 100b' of the display screen 100b' at the sound outlet hole 30' being unequal in width to the black border area 100b' at other parts, affecting the appearance of the electronic device 00'.
[0069] In order to solve the above problems, an embodiment of the present application provides an electronic device. In the embodiment of the present application, a sound output channel can be formed without opening a channel 21b' in the middle frame. Therefore, at the position corresponding to the sound output channel, the size of the black border area of the display screen does not need to include the size of the channel wall of the channel 21b', thereby reducing the size of the black border area and improving the screen-to-body ratio of the electronic device. In addition, the black border areas of each part of the display screen can have equal widths, thereby improving the appearance refinement of the display screen.
[0070] The following combination FIG. 3A to FIG. 3F The specific structure of the electronic device and its sound output channel provided by the embodiment of the present application is introduced. Figure 3A is a front view of the electronic device 00, Figure 3B A perspective view of the electronic device 00 is shown (without the display screen). Figure 3C A cross-sectional view of an electronic device 00 is shown. Figure 3B BB cross-section), Figure 3D A cross-sectional view of the electronic device 00 is shown in FIG. Figure 3B Cross-sectional view of CC in the middle), Figure 3E A cross-sectional view of the electronic device 00 is shown in FIG. Figure 3B (a cross-sectional view of EE in Fig. Figure 3F A cross-sectional view of a housing 200 of an electronic device 00 is shown ( Figure 3B (a cross-sectional view of DD in Fig.
[0071] Refer to 3A, Figure 3B and Figure 3F The electronic device 00 includes a display screen 100 , a housing 200 , a first sealing member 300 and a second sealing member 400 .
[0072] As described above, the housing 200 includes a middle frame 21 and a back cover 22 (or "battery cover"), and the middle frame 21 includes a panel 210 and a side wall 220 surrounding the panel 210 along the circumference of the panel 210. The panel 210 extends along the XY plane (as a first plane). In some embodiments, the panel 210 may be parallel to the XY plane. In other embodiments, the panel 210 may also be slightly inclined to the XY plane. In addition, the panel 210 may be a plane or a curved surface.
[0073] The side wall 220 is connected to the panel 210 and extends along the Z direction (as the first direction) to enclose the front cavity 230 of the electronic device together with the panel 210. The opening of the front cavity 230 faces the Z direction, and the Z direction is perpendicular to the XY plane (as the first plane). In some embodiments, the side wall 220 may include, for example, a top wall 220a, a bottom wall 220c, a left side wall 220d, and a right side wall 220b. The top wall 220a, the bottom wall 220c, the left side wall 220d, and the right side wall 220b completely surround the panel 210 and form a rectangular frame structure. In other embodiments, the side wall 220 may also partially surround the panel 210, for example, the side wall 220 only includes the top wall 220a and the bottom wall 220c.
[0074] Reference FIG. 3B to FIG. 3C The top wall 220a includes a first subsection 221 extending along the circumference of the panel 210, and the panel 210 includes a first area 211 connected to the first subsection 221 (for ease of observation, Figure 3B The first area 211 is located in the figure with a dotted line, and a sound hole 212 is opened in the first area 211, wherein the sound hole 212 is connected to the rear cavity 20a, and a sound-generating device 24 (such as a speaker module, an earpiece, etc.) is provided in the rear cavity 20a.
[0075] For example, in this embodiment, the first subsection 221 is located at the top wall 220a of the middle frame 21 of the housing 200. In other embodiments, the first subsection 221 may also be located at other positions of the middle frame 21, such as at the left side wall 220d or the right side wall 220b of the middle frame 21 extending along the X direction (as the second direction). The embodiment of the present application does not limit the position of the first subsection 221.
[0076] Reference FIG. 3C to FIG. 3E , the display screen 100 includes a cover plate 110 and a display module 120 stacked on each other along the Z direction. In some embodiments, the cover plate 110 may be, for example, a glass cover plate, which may be used as the outermost component of the display screen 100 to protect the display module 120 and other internal components of the electronic device 100. The display module 120 may be, for example, a liquid crystal display (LCD) module or an OLED display module. The cover plate 110 is covered on the side wall 220 along the Z direction so that the display screen 100 is connected to the housing 200. That is, by connecting the cover plate 110 to the side wall 220, the display screen 100 and the housing 200 may be connected (for example, fixedly connected). Exemplarily, the connection method between the cover plate 110 and the side wall 220 may be bonding.
[0077] Reference Figure 3DThere is a gap between the cover plate 110 and the first subsection 221 of the side wall 220, and the gap forms the first sound outlet 510. Exemplarily, in some embodiments, the side wall 220 is provided with a notch on the first subsection 221. When the cover plate 110 of the display screen 100 is covered on the side wall 220, the cover plate 110 and the side wall 220 form the first sound outlet 510 at the notch portion of the first subsection 221.
[0078] The display module 120 is located in the front cavity 230, and the display module 120 and the first area 211 of the panel 210 are opposite and spaced apart along the Z direction. The first sealing member 300 is disposed between the display module 120 and the panel 210, and is disposed at least partially around the first area 211 of the panel 210 along the circumference of the first area 211, so as to enclose a first sound cavity 520 between the display module 120 and the panel 210.
[0079] For example, in some embodiments of the present application, reference is made to Figure 3B The first sealing member 300 is a continuous structure extending along the circumference of the first area 211. The first sealing member 300 is along three sides of the first area 211, and the other side of the first area 211 is sealed by the first sub-segment 221. Thus, the first sealing member 300 and the first sub-segment 221 can completely surround the first area 211 along the circumference of the first area 211, thereby sealing the first sound cavity 520 along the circumference 211 of the first area.
[0080] The first sealing member 300 may be, for example, foam or foam glue, and along the Z direction, two surfaces of the first sealing member 300 may be respectively attached to the display module 120 and the panel 210. That is, the first sound cavity 520 may be understood to be surrounded by the display module 120, the panel 210, the first sealing member 300 and the first sub-segment 221.
[0081] The display module 120 and the first sub-section 221 of the side wall 220 are opposite to and spaced apart from each other along the X direction (as the second direction), and the X direction is perpendicular to the Z direction. The second sealing member 400 is disposed between the first sub-section 221 of the side wall 220 and the display module 120 to enclose a second sound cavity 530 between the side wall 220 and the display module 120.
[0082] For example, refer to FIG. 3B to FIG. 3EIn some embodiments of the present application, the second seal 400 is a structure extending along the Z direction. Along the X direction, the two surfaces of the second seal 400 are respectively in contact with the side wall 220 and the display module 120. The second seal 400 can be, for example, foam, foam glue or dam glue. There are two second seals 400, and along the Y direction, the two second seals 400 are respectively arranged on both sides of the first sound outlet 510. That is, the second sound cavity 530 can be understood as being surrounded by the first sub-segment 221, the display module 120, and the two second seals 400. It can be understood that the second seal 400 can also prevent foreign matter from entering the display module 120, thereby improving the reliability of the display module 120.
[0083] The above-mentioned sound hole 212, the first sound cavity 520, the second sound cavity 530 and the first sound outlet 510 are connected in sequence to form a first sound outlet channel 500. In other words, the sound emitted by the sound-emitting device 24 of the electronic device 00 can be transmitted to the outside of the electronic device 00 through the sound hole 212, the first sound cavity 520, the second sound cavity 530 and the first sound outlet 510 in sequence to realize the sound emission of the electronic device 00.
[0084] Since the second sound cavity 530 is surrounded by the second sealing member 400, the side wall 220 and the display module 120, rather than being formed by providing a channel in the middle frame, the black border area 100b of the display screen 100 does not need to include the Figure 2C The dimension d2 shown can thus reduce the size of the black border region 100b.
[0085] Reference Figure 3D , the black border area 100b of the display screen 100 may include the following parts:
[0086] (1) d1, i.e., the width of the cover plate 110 of the display screen 100 covering the side wall 220 (i.e., the width of the step glue 240 dispensing area). When the cover plate 110 is covered on the side wall 220, the cover plate 110 and the side wall 220 need to be attached by the step glue 240. As described above, due to the limitation of the needle size of the dispensing equipment for adding the step glue 240, the width d1 of the step glue 240 dispensing area can be 0.55 mm.
[0087] (2) d3, that is, the avoidance distance between the display module 120 and the side wall 220. To ensure that the display module 120 does not interfere with the side wall 220, after the display module 120 is installed in the front cavity 230, the avoidance distance between the display module 120 and the side wall 220 may be 0.4 mm.
[0088] It should be understood that the avoidance distance d3 between the display module 120 and the side wall 220 can form a second sound cavity 530. Therefore, the second sound cavity 530 can be provided without additionally increasing the width of the black border area 100b of the display screen 100.
[0089] (3) d4, i.e., the edge area of the display module 120 body. The edge area of the display module 120 body is the non-display part of the display module 120 and can be used for packaging, wiring, etc. The width of this area can be 1 mm.
[0090] Therefore, at the corresponding position of the sound outlet channel 500, the size of the black border area 100b of the display screen 100 can be d1+d3+d4=1.95mm. In addition, the dimension d5 from the edge of the cover plate 110 of the display screen 100 to the edge of the electronic device 00 is usually 1.10mm. Therefore, the size from the edge of the display area 100a of the display screen 100 to the edge of the electronic device 00 is d1+d3+d4+d5=3.05mm. Therefore, the size from the display area 100a of the electronic device 00 to the edge of the electronic device 00 can be reduced to 3.05mm, which is more than 1mm less than the size from the display area 100a of the electronic device 00' to the edge of the electronic device 00'. Therefore, the display area 100a of the electronic device 00 in the embodiment of the present application is expanded, and the screen-to-body ratio of the electronic device 00 is further improved.
[0091] Furthermore, since the width of the black border area 100b at the top of the display screen 100 is not increased to cover the second sound cavity 530, the black border area 100b at the top of the display screen 100 is the same width as the black border area 100b at other parts of the display screen 100, thereby improving the appearance refinement of the electronic device.
[0092] Continue to refer FIG. 3B to FIG. 3E The first sound outlet channel 500 is not connected to other parts of the front cavity 230 except the first sound cavity 520 and the second sound cavity 530. The first sound outlet channel 500 is a channel formed by the sound hole 212, the first sound cavity 520, the second sound cavity 530 and the first sound outlet 510.
[0093] For example, refer to Figure 3B The first sealing member 300 is similar to a "U"-shaped structure on the XY plane, the opening of the "U"-shaped structure is opposite to the side wall 220, and the interior of the "U"-shaped structure is the first area 211. Therefore, the first sealing member 300 and the side wall 220 surround the first area 211 on the -Y plane.
[0094] Reference Figure 3B, the first sealing member 300 is in contact with the display module 120 and the panel 210 along the Z direction. Therefore, along the Z direction, the space surrounded by the "U"-shaped structure (i.e., the first sound cavity 520) is a sealed space. Therefore, the sound emitted by the sound hole 212 can only be transmitted through the opening part of the "U"-shaped structure. However, along the X direction, the opening part of the "U"-shaped structure is sealed by the side wall 220, and since the display module 120 and the side wall 220 are spaced apart along the X direction, the sound can be transmitted from the gap (i.e., the second sound cavity 530) between the display module 120 and the side wall 220. In order to ensure the sealing of the gap between the display module 120 and the side wall 220. The spaced display module 120 and the side wall 220 are sealed by two second sealing members 400, and the two second sealing members 400 are respectively arranged at the two ends of the "U"-shaped structure, so as to form a second sound cavity 530 between the spaced display module 120 and the side wall 220. Therefore, the sound transmitted to the first sound cavity 520 by the sound hole 212 can only be transmitted to the first sound outlet 510 through the second sound cavity 530 , and thus transmitted out of the electronic device 00 .
[0095] It should be understood that the first sound outlet channel 500 is used to connect the sound hole 212 with the first sound outlet 510 to transmit the sound through the sound hole 212 and the first sound outlet 510, and the first sound outlet channel 500 needs to remain sealed from other parts to ensure the effect of the first sound outlet channel 500 in transmitting sound.
[0096] It can be understood that the first sound cavity 520 is a sealed space formed by the first seal 300, the display module 120 and the panel 210 in the first area 211. The sound-emitting component of the electronic device 00 can transmit the sound to the first sound cavity 520 through the sound hole 212. The second sound cavity 530 is a sealed space formed by the second seal 400, the side wall 220 and the display module 120 at the first subsection 221, and the second sound cavity 530 is connected with the first sound cavity 520 and the first sound outlet 510. Therefore, the sound can be transmitted from the first sound cavity 520 to the second sound cavity 530, and then transmitted to the outside through the first sound outlet 510, so that the sound of the electronic device 00 can be transmitted.
[0097] Reference Figure 3D , along the X direction, the spacing between the display module 120 and the side wall 220 is 0.15mm~0.3mm, for example, 0.2mm, 0.25mm, etc. It should be understood that the display module 120 and the side wall 220 are used to form a second sound cavity 530. Therefore, a spacing needs to be maintained between the display module 120 and the side wall 220 to ensure the sound effect. However, when the spacing is too large, the width of the black border area will increase and the screen-to-body ratio will be reduced. In this embodiment, the spacing between the display module 120 and the side 220 is set to 0.15mm~0.3mm, which can take into account the requirements of both the sound effect and the screen-to-body ratio.
[0098] refer to FIG. 3B to FIG. 3E In some embodiments, along the Z direction, the size of the first sealing member 300 may be, for example, between 0.8 mm and 2 mm, for example, 1 mm. In other embodiments, the size of the first sealing member 300 in the Z direction may also be other values.
[0099] refer to Figure 3B , along the X direction, the size of the first seal 300 can be, for example, 8 mm to 15 mm, for example, 10 mm. Along the Y direction, the size of the first seal 300 can be, for example, between 30 mm and 45 mm, for example, 35 mm. Through this arrangement, while providing effective sealing for the first sound cavity 520, it can also reduce the difficulty of setting the first seal 300, save the material of the first seal 300, and reduce the cost of the electronic device 00. In other embodiments, the size of the first seal 300 in the X direction and / or the Y direction can also be other values.
[0100] Continue to refer FIG. 3B to FIG. 3E The side wall 220 includes a thickness direction (a direction perpendicular to the circumference of the display screen 100, for example FIG. 3C to FIG. 3E The first part 222 and the second part 223 are stacked (in the X direction), and the thickness direction of the side wall 220 is perpendicular to the circumference of the panel 210. The first part 222 is located outside the second part 223, and, along the first direction, the first part 222 protrudes from the second part 223. The cover plate 120 of the display screen 100 is covered on the second part 223, and, along the thickness direction of the side wall 220, the first part 223 at least partially covers the cover plate 120.
[0101] refer to FIG. 3C to FIG. 3E That is, the cross section of the side wall 220 is a step structure, the first portion 222 is a high step, and the second portion 223 is a low step. The cover plate 210 is covered on the low step, that is, the cover plate 210 is covered on the second portion 223, and the first portion 223 at least partially covers the cover plate 120.
[0102] Since the cover plate 210 is covered on the second part 223, the first part 222 can protect the cover plate 120, prevent the cover plate 120 from being damaged along the side, and shield the electronic device 00 from external impurities and moisture, and prevent moisture and impurities from entering the interior of the electronic device 00 through the gap between the cover plate 120 and the second part 223.
[0103] It should be understood that in some embodiments of the present application, the cover plate 120 and the side wall 220 are bonded to each other through the step glue 240 (as the second colloid). For example, the cover plate 120 is bonded to the second part 223 through the step glue 240, and the circumferential edge of the cover plate 120 is in contact with the first part 222. Bonding the cover plate 120 to the second part 223 of the side wall 220 through the step glue 240 can ensure the sealing performance of the electronic device 00, and the first part 222 protrudes from the second part 223, which can protect the display screen 100 of the electronic device 00.
[0104] refer to Figure 3B and Figure 3F , the portion of the first subsection 221 used to form the first sound outlet 510 does not include the second portion 223. It should be understood that since the second portion 223 is not provided at the first subsection 221 (i.e., a notch is provided at the portion of the first subsection 221 of the side wall 220), the side wall 220 has no structure for receiving the cover plate 110 at the first subsection 221, so that the first sound outlet 510 is formed between the portion of the first subsection 221 of the side wall 220 and the cover plate 110. The first sound outlet 510 is in communication with the second sound cavity 530.
[0105] refer to Figure 3B , along the circumference of the panel 210, the first sound outlet 510 is located at the center of the first sub-segment 221. For example, in some embodiments of the present application, the first sound outlet 510 is set at the center of the first sub-segment 221. In other embodiments, the first sound outlet 510 can also be located at other positions of the first sub-segment 221, for example, the first sound outlet 510 is located at a position off the center of the first sub-segment 221. The embodiments of the present application do not limit the position of the first sound outlet 510 at the first sub-segment 221.
[0106] Figure 4 A partial view (stereoscopic view) of the top position of the electronic device 00 is shown. Figure 3D and Figure 4 The side wall 220 is further provided with a second sound outlet 610 at the position of the first subsection 221 , and the second sound outlet 610 and the first sound cavity 520 together form a second sound outlet channel 600 .
[0107] For example, the second sound outlet 610 can be a single hole structure or a row of hole structures, such as 2 holes in a row to 4 holes in a row. The second sound outlet 610 penetrates the first subsection 221 of the side wall 220 along the X direction, so that the second sound outlet 610 is connected to the first sound cavity 510.
[0108] Continue to refer Figure 3D and Figure 4In some embodiments, the rear shell 22 covers the second sound outlet 610. In order to make the electronic device emit sound smoothly, the portion of the rear shell 22 corresponding to the second sound outlet 610 is further provided with a third sound outlet 630 corresponding to the second sound outlet 610, and the second sound outlet 610 is connected to the third sound outlet 630. For example, the third sound outlet 630 and the second sound outlet 610 are also a single hole structure or a row of hole structures. Therefore, the sound of the second sound outlet channel 600 can also be transmitted to the outside of the electronic device 00 through the third sound outlet 630 to improve the sound effect of the electronic device 00.
[0109] It should be understood that in the embodiments of the present application, a third sealant 620 may be further provided around the second sound outlet 610 and the third sound outlet 630, and the two sides of the third sealant 620 along the X direction are respectively fitted with the side wall 220 and the rear shell 22 to seal the gap between the second sound outlet 610 and the third sound outlet 630 (i.e., the gap between the rear shell 22 and the side wall 220 in the first sub-segment 221) along the circumference of the second sound outlet 610, thereby improving the sound output effect of the electronic device 00 in the second sound outlet channel 600.
[0110] refer to FIG. 3C to FIG. 3E The display module 120 includes a main body 121 and a screen sealing glue 122 (also called "first glue" or side sealing glue). The main body 121 includes a multi-layer structure stacked along the Z direction. The screen sealing glue 122 is adhered to the multi-layer structure along the second direction to close the gaps between different layers of the multi-layer structure.
[0111] It should be understood that since the electronic device 00 has a first sound outlet 510 at the first subsection 221 of the side wall 220, moisture or impurities outside the electronic device 00 can easily enter the second sound cavity 530 through the first sound outlet 510. In order to ensure that the multi-layer structure of the body 121 is not affected by moisture or impurities, a screen-sealing glue 122 can be provided at the part of the body 121 located at the first subsection 221 to close the gaps between different layers of the multi-layer structure, thereby protecting the display module 120. In the embodiment of the present application, the screen-sealing glue 122 is only required to be applied to the part of the body 121 at the first subsection 221, and no glue is required to be applied to other parts of the body 121, thereby reducing the processing difficulty of the body 121 and saving the glue application cost of the body 121. Exemplarily, in the embodiment of the present application, the screen-sealing glue 122 can be, for example, a side seam glue. In other embodiments, the screen-sealing glue 122 can also be, for example, other types of colloids. The present application does not limit the screen-sealing glue 122.
[0112] It should be understood that in other embodiments, the display screen and the housing of the electronic device may be directly attached together, for example, that is, there is no corresponding side wall on the middle frame of the electronic device to accommodate the display screen.
[0113] The following describes a comparison between the structure of the electronic device in the embodiment of the present application and the structure of the electronic device in some other embodiments.
[0114] FIG. 5A to FIG. 5C Schematic diagram of the structure of electronic device 00" in some other embodiments is shown. Figure 5A The front view of the electronic device 00" is shown in FIG. Figure 5B is a cross-sectional view of an electronic device 00", Figure 5C It is a top view of the electronic device 00 ″ (excluding the display screen 100 ″).
[0115] refer to FIG. 5A to FIG. 5C The surface of the panel 210 ″ of the housing 200 ″ is provided with a colloid 700 , and the display screen 100 ″ is bonded to the panel 210 ″ on the housing 200 ″ through the colloid 700 , so that the display screen 100 ″ is fixedly connected to the housing 200 ″.
[0116] In addition, the side wall 220" of the shell 200" includes an upper side wall 220a" and a lower side wall 220c", and a first sound outlet 510" is provided on the upper side wall 220a". The panel 210" also has a sound hole 212", and when the display screen 100" and the panel 210" are fixed by the colloid 700, a first sound cavity is formed at the sound hole 212". The display screen 100" and the upper side wall 220a and the second seal 400" form a second sound cavity at the first sound outlet 510" of the upper side wall 220a". The sound hole 212", the first sound cavity, the second sound cavity and the first sound outlet 510" form a sound outlet channel of the electronic device 00".
[0117] like Figure 5B As shown, the display screen 100" is adhered to the panel 210" through the colloid 700. In the embodiment of the present application, the middle frame and the rear shell are integrated into a shell 200". Therefore, when the display screen 100" and the panel 210" are fixed by the colloid 700, a large amount of colloid 700 is required. In addition, the panel 210" needs to be a flexible panel such as an OLED panel.
[0118] Reference Figure 5C , a sealing area 710 is provided on the panel 210", and the sealing area 710 needs to be entirely provided with colloid 700 to fix the display screen 100" and the panel 210" of the shell 200". Since the display screen 100" requires a large amount of colloid 700 to be fixed to the panel 210", the process of fixing the display screen 100" and the panel 210" of the electronic device 00" is relatively complicated, and the fixing cost is relatively high. In the embodiment of the present application, the display screen 100 of the electronic device 00 and the middle frame 21 are fixed by a step glue 240 (that is, the second colloid) provided on the side wall 220 of the middle frame 21. Therefore, the fixing process can be simplified and the amount of glue can be saved, thereby not only saving the cost of the electronic device, but also reducing the difficulty of disassembly.
[0119] In the above description of this embodiment, unless otherwise specified, “ / ” means or, for example, A / B can identify A or B; “and / or” in this article is merely a way to describe the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can represent the existence of A alone, B alone, and A and B at the same time.
