Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly relates to a housing and an electronic device. Background Art

[0002] At present, electronic devices such as mobile phones and computers have become inseparable from our lives, greatly facilitating people's lives. The display screen and the housing are two important components of an electronic device. In related technologies, in order to achieve a fixed connection between the display screen and the housing, generally a boss is provided on the inner peripheral wall of the housing frame portion, the light-transmitting cover plate of the display screen is supported on the boss, and a colloid is provided between the light-transmitting cover plate and the boss to bond the light-transmitting cover plate to the boss.

[0003] Since people's requirements for the screen appearance of electronic devices are getting higher and higher, the higher the screen-to-body ratio, the better the visual effect. Therefore, the narrow bezel and full-screen design have become the development trend. In order to increase the screen-to-body ratio of an electronic device, the width of the boss is made narrower and narrower, resulting in a narrower bonding width between the boss and the light-transmitting cover plate. In this way, the colloid is not easily evenly pressed open between the boss and the light-transmitting cover plate, and there will be a sealing gap between the boss and the light-transmitting cover plate, leading to sealing failure.

[0004] It can be understood that there will inevitably be a gap between the display screen and the frame portion of the housing. External grease and water stains (such as the user's sweat, etc.) are likely to accumulate in this gap. At this time, the grease and water stains are easily introduced into the display screen through the sealing gap between the boss and the light-transmitting cover plate to erode the display screen, resulting in yellow spots on the display screen and affecting the display effect of the display screen. Summary of the Invention

[0005] This application provides a housing and an electronic device, which can timely guide the grease and water stains at the gap between the display screen and the frame portion of the housing to the sound passage opening through the diversion groove, thereby preventing the grease and water stains from entering the display screen to erode the display screen.

[0006] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, a housing is provided. The housing includes: a frame portion, a boss is provided on the inner peripheral wall of the frame portion, the boss extends along the circumferential direction of the frame portion, the boss has a bearing surface for bonding the light-transmitting cover plate of the display screen; wherein, the boss has a sound passage opening, a diversion groove with an open front side is provided on the boss, the diversion groove and the bearing surface are located on the same wall surface of the boss, and one end of the diversion groove penetrates the side wall surface of the boss facing the sound passage opening.

[0008] In this way, grease and water stains from the outside can fall onto the wall surface of the boss where the bearing surface is located through the gap between the transparent cover plate and the frame portion, and then be collected into the guide groove. Since the first end of the guide groove passes through the side wall surface of the boss facing the sound-passing opening, that is, the guide groove is connected with the sound-passing opening through its first end, the grease and water stains collected in the guide groove can be promptly guided to the sound-passing opening through the first end of the guide groove, thereby avoiding the accumulation of grease and water stains on the wall surface of the boss where the bearing surface is located, and further avoiding the grease and water stains from passing through the sealed gap between the bearing surface and the transparent cover plate and entering the interior of the display screen to erode the display screen.

[0009] In one possible implementation of the first aspect, the guide groove is located on the side of the bearing surface facing the frame portion. Thus, the guide groove can be directly opposite the gap between the frame portion and the light-transmitting cover plate, or relatively close to the gap, thereby facilitating the entry of water stains and grease into the guide groove and allowing the water stains and grease to be more promptly directed out of the boss wall where the bearing surface is located.

[0010] In one possible implementation of the first aspect, the end of the guide groove that extends through the sidewall of the boss and faces the sound-passing opening is the first end, and the end of the guide groove that is away from the first end is the second end. The bottom wall of the guide groove extends obliquely away from the front side in the direction from the second end toward the first end. This ensures that the bottom wall of the guide groove extends obliquely in the direction of gravity acting on grease and water stains in the direction from the second end toward the first end. As a result, grease and water stains collected in the guide groove can flow more quickly and smoothly from the second end to the first end, and then be guided from the first end to the sound-passing opening.

[0011] In one possible implementation of the first aspect, a height difference ΔH between the bottom wall at the second end and the bottom wall at the first end is greater than or equal to 0.3 mm. This allows the bottom wall of the guide groove to have a larger inclination angle, thereby improving the guide groove's ability to guide grease and water stains. Grease and water stains within the guide groove can be more quickly and smoothly directed to the sound passage opening.

[0012] In one possible implementation of the first aspect, the frame portion is provided with a sound passage, which is connected to the sound passage opening. In this way, sound can be transmitted between the audio device and the outside world not only through the sound passage gap provided between the frame portion and the display screen, but also through the sound passage, thereby increasing the total sound passage area. This balances the airflow within the sound passage, thereby avoiding the problem of noise caused by a large airflow within the sound passage due to a small cross-sectional area of the sound passage. In addition, by providing the sound passage opening in the portion of the frame portion where the sound passage opening is located, grease and water stains directed to the sound passage opening can be discharged to the outside of the housing through the sound passage, preventing them from accumulating inside the housing and corroding other components within the electronic device, thereby further improving the reliability of the electronic device and extending its service life.

[0013] In a possible implementation of the first aspect, the housing further includes a middle plate portion. The frame portion is disposed around the edge of the middle plate portion. The boss is located on the front side of the middle plate portion. The middle plate portion is provided with a sound passage groove that is open at the front side. The sound passage groove communicates with the sound passage opening. The bottom wall of the sound passage groove is provided with an opening for communicating with the audio device. In this way, the communication channel for communicating the audio device with the sound passage gap between the display module and the middle plate portion is formed between the display module and the sound passage groove, so that the cross-sectional area of the communication channel can be increased without increasing the overall gap between the display module and the middle plate portion, which is beneficial to the thinning of the electronic device.

[0014] In a possible implementation of the first aspect, the sound passage groove is provided with a rib to divide the sound passage groove into a first sound passage groove portion and a second sound passage groove portion. The second sound passage groove portion is located on the side of the first sound passage groove portion away from the sound passage opening. The opening is provided on the bottom wall of the second sound passage groove portion. In this way, the grease and water stains at the sound passage opening can be collected in the first sound passage groove portion, which can prevent the grease and water stains from spreading wantonly inside the electronic device and eroding other components inside the electronic device. In addition, the first sound passage groove portion and the second sound passage groove portion are separated by the rib, and the first sound passage groove portion and the second sound passage groove portion are not communicated with each other, so that the grease and water stains collected in the first sound passage groove portion will not enter the second sound passage groove portion, thereby preventing the grease and water stains from eroding the audio device through the opening.

[0015] In a possible implementation of the first aspect, the front edge of the rib is located at the rear side of the front edge of the sound passage groove. In this way, the gap between the front edge of the rib and the display module is greater than the gap between the front edge of the sound passage groove and the display module, thereby preventing the setting of the rib from affecting the cross-sectional area of the communication channel between the audio device and the sound passage gap and ensuring normal sound passage between the audio device and the outside.

[0016] In a possible implementation of the first aspect, the bottom wall of the first sound passage groove portion is provided with a plurality of protrusions arranged in an array. This can increase the water droplet angle between the grease and water stains and the bottom wall of the first sound passage groove portion, and the grease and water stains can be better aggregated in the first sound passage groove portion, so as to facilitate the discharge of the grease and water stains to the outside of the electronic device through the sound passage opening.

[0017] In a possible implementation of the first aspect, a sound passage port is provided at a part of the frame portion where the sound passage opening is located. The sound passage port communicates with the first sound passage groove portion. In this way, the grease and water stains collected in the first sound passage groove portion can be discharged to the outside of the electronic device through the sound passage port.

[0018] In a possible implementation of the first aspect, a part of the frame portion where the sound passage opening is located forms a part of the side wall of the first sound passage groove portion, and the sound passage opening is located on the side wall of the first sound passage groove. In this way, the first sound passage groove portion can be closely attached to the frame portion where the sound passage opening is located, and the grease and water stains in the area where the frame portion where the sound passage opening is located can directly flow into the first sound passage groove portion, so as to better avoid the erosion of other components inside the electronic device by the grease and water stains.

[0019] In a possible implementation of the first aspect, one end of the side wall surface of the through convex platform of the diversion groove facing the sound passage opening is the first end, and the projection of the edge of the first end on the front wall surface of the middle plate portion overlaps with the projection of the edge of the first sound passage groove portion on the front wall surface of the middle plate portion; or the projection of the edge of the first end on the front wall surface of the middle plate portion is located within the projection area of the first sound passage groove portion on the front wall surface of the middle plate portion. In this way, when the grease and water stains in the diversion groove are guided from the first end towards the sound passage opening, the grease and water stains can be directly guided to the first sound passage groove portion along the side wall surface of the convex platform without flowing to other areas on the middle plate portion, so as to better avoid the erosion of other components inside the electronic device by the grease and water stains.

[0020] In a possible implementation of the first aspect, the width of the side wall surface of the convex platform facing the sound passage opening gradually decreases in the front-to-back direction. This can make the side wall surface of the convex platform facing the sound passage opening have a diversion effect, so that the grease and water stains on the diversion groove and the bearing surface can be guided to the first sound passage groove portion more quickly and smoothly.

[0021] In a possible implementation of the first aspect, a first arc transition surface is provided between the side wall surface of the convex platform facing the sound passage opening and the bearing surface; and / or a second arc transition surface is provided between the side wall surface of the convex platform facing the sound passage opening and the bottom wall of the diversion groove. By providing the first arc transition surface, a smooth transition can be achieved between the bearing surface and the side wall surface of the convex platform facing the sound passage opening, so that the grease and water stains on the bearing surface can be more smoothly guided to the side wall surface of the convex platform facing the sound passage opening through the first arc transition surface. Similarly, by providing the second arc transition surface, a smooth transition can be achieved between the bottom wall of the diversion groove and the side wall surface of the convex platform facing the sound passage opening, so that the grease and water stains in the diversion groove can be more smoothly guided to the side wall surface of the convex platform facing the sound passage opening through the second arc transition surface.

[0022] In a possible implementation of the first aspect, one end of the bearing surface facing the sound conduction opening has a first guiding section surface, and the width of the first guiding section surface gradually decreases in the direction facing the sound conduction opening; and / or one end of the diversion groove facing the sound conduction opening has a second guiding section surface, and the width of the second guiding section surface gradually decreases in the direction facing the sound conduction opening. In this way, the first guiding section surface has the function of guiding grease and water stains towards the sound conduction opening, and the grease and water stains on the bearing surface can be smoothly and quickly guided to the sound conduction opening through the first guiding section surface, preventing the grease and water stains from accumulating on the bearing surface and entering the display screen to erode the display screen. The second guiding section surface has the function of guiding grease and water stains towards the sound conduction opening, and the grease and water stains in the diversion groove can be smoothly and quickly guided to the sound conduction opening through the second guiding section surface, preventing the grease and water stains from accumulating in the diversion groove.

[0023] In a possible implementation of the first aspect, the edge of the first guiding section surface facing the sound conduction opening is an arc protruding towards the sound conduction opening; and / or the edge of the second guiding section surface facing the sound conduction opening is an arc protruding towards the sound conduction opening. In this way, the edges of the first guiding section surface and the second guiding section surface facing the sound conduction opening are relatively smooth, and the structure is beautiful and convenient for processing.

[0024] In a possible implementation of the first aspect, the inner wall surface of the convex platform extends obliquely towards the direction close to the frame part in the front-to-back direction. This can reduce the space occupied by the convex platform inside the housing while ensuring that the front wall surface of the convex platform has a large area, thereby ensuring the area of the bearing surface on the front wall surface of the convex platform, and further ensuring the reliability of the connection between the light-transmitting cover plate and the bearing surface. In addition, by reducing the space occupied by the convex platform inside the housing, the utilization rate of the internal space of the housing can be improved.

[0025] In a possible implementation of the first aspect, the convex platform includes a main body section and an avoidance section. The avoidance section is connected to the main body section and extends to the sound conduction opening. Compared with the inner wall surface of the main body section, the inner wall surface of the avoidance section is closer to the frame part. By making the inner wall surface of the avoidance section closer to the frame part, the avoidance section has an avoidance effect on the side sealant, and the avoidance section creates a accommodation space for the side sealant. The circumferential end of the side sealant extends to the inner side of the inner wall surface of the avoidance section, but does not extend to the inner side of the inner wall surface of the main body section.

[0026] In a possible implementation of the first aspect, the length of the diversion groove extending along the circumferential direction of the frame part is greater than or equal to the length of the avoidance section extending along the circumferential direction of the frame part. In this way, it can be ensured that the grease and water stains on the wall surface of the convex platform where the bearing surface of the avoidance section is located can be timely guided to the sound conduction opening through the diversion groove.

[0027] Second aspect, there is also provided an electronic device, which includes: a display screen and a housing as described in any of the above technical solutions. The display screen includes a light-transmitting cover plate and a display module; the light-transmitting cover plate is bonded to the bearing surface, a sound passage gap is provided between the frame portion and the display screen, and a sound passage communicating with the sound passage gap is formed among the display screen, the sound passage opening and the frame portion.

[0028] Since the electronic device provided in the present application includes a housing as described in any of the above technical solutions, both can solve the same problems and achieve the same effects. BRIEF DESCRIPTION OF THE DRAWINGS

The light-transmitting cover plate 21 and the display module 22 can be relatively fixed by adhesive connection. Exemplarily, the light-transmitting cover plate 21 and the display module 22 can be adhesively fixed by OCA glue (optical clear adhesive).

[0069] Among them, the area of the light-transmitting cover plate 21 is larger than the area of the display module 22, and the circumferential side surface of the light-transmitting cover plate 21 protrudes from the circumferential side surface of the display module 22. The light-transmitting cover plate 21 completely covers the display module 22. The light-transmitting cover plate 21 is mainly used to protect the display module 22 and prevent dust. The material of the light-transmitting cover plate 21 includes but is not limited to glass. The light-transmitting cover plate 21 also has functions such as anti-impact, scratch resistance, oil resistance, fingerprint prevention, and enhanced light transmittance.

[0070] The display module 22 can be a flexible display module or a rigid display module. For example, the display module 22 can be an organic light-emitting diode (OLED) display module, an active-matrix organic light-emitting diode (AMOLED) display module, a mini organic light-emitting diode display module, a micro organic light-emitting diode display module, a quantum dot light-emitting diode (QLED) display module, a liquid crystal display (LCD), etc.

[0071] The display screen 2 is connected to the housing 1. Specifically, the light-transmitting cover plate 21 of the display screen 2 is connected to the housing 1, and the back cover 11 is located on the side of the display screen 2 away from the light-transmitting cover plate 21. When the electronic device 100 does not include the front shell 13 in the above embodiments, please refer to Figure 3 , the edge portion of the light-transmitting cover plate 21 can be bonded to the frame 121, so as to realize the connection between the light-transmitting cover plate 21 and the housing 1. At this time, the frame 121 is located between the light-transmitting cover plate 21 and the back cover 11. The light-transmitting cover plate 21, the frame 121 and the back cover 11 jointly form the external structure of the electronic device 100, and devices such as the display module 22, the circuit board 3, and the battery 4 are all located inside the electronic device 100. When the electronic device 100 includes the front shell 13 in the above embodiments, please refer to Figure 4 , the edge portion of the light-transmitting cover plate 21 can be bonded to the front frame 131, so as to realize the connection between the light-transmitting cover plate 21 and the housing 1. At this time, both the front frame 131 and the frame 121 are located between the light-transmitting cover plate 21 and the back cover 11. The light-transmitting cover plate 21, the front frame 131, the frame 121 and the back cover 11 jointly form the external structure of the electronic device 100, and devices such as the display module 22, the circuit board 3, and the battery 4 are all located inside the electronic device 100.

[0072] As can be seen from the above, the light-transmitting cover plate 21 can be connected to the frame 121 or the front frame 131. For the convenience of description below, the "frame 121" or "front frame 131" connected to the light-transmitting cover plate 21 is defined as the "frame portion 101" here. That is to say, when the housing 1 does not include the front shell 13 and the edge of the light-transmitting cover plate 21 is bonded to the frame 121, please refer toFigure 3 , at this time, the frame part 101 refers to the frame 121; when the housing 1 includes the front shell 13 and the edge of the light-transmitting cover plate 21 is bonded to the front frame 131, please refer to Figure 4 , at this time, the frame part 101 refers to the front frame 131.

[0073] Meanwhile, here, the "middle plate 122" or the "front middle plate 132" is also defined as the "middle plate part 102". When the frame 121 serves as the frame part 101, at this time, the middle plate 122 serves as the middle plate part 102; when the front frame 131 serves as the frame part 101, at this time, the front middle plate 132 serves as the middle plate part 102.

[0074] Please refer to Figure 4 , a boss 1011 is provided on the inner peripheral wall of the frame part 101. The boss 1011 extends along the circumferential direction of the frame part 101. The boss 1011 has a bearing surface 10111, and the bearing surface 10111 is used for bonding the light-transmitting cover plate 21 of the display screen 2. By providing the boss 1011 on the inner peripheral wall of the frame part 101, a bearing surface 10111 for supporting and bonding the light-transmitting cover plate 21 can be formed on the boss 1011. A colloid 1004 is provided between the light-transmitting cover plate 21 and the bearing surface 10111 to bond the light-transmitting cover plate 21 to the bearing surface 10111. By bonding the light-transmitting cover plate 21 to the bearing surface 10111, the light-transmitting cover plate 21 is bonded to the frame part 101.

[0075] Since people's requirements for the screen appearance of the electronic device 100 are getting higher and higher, the higher the screen-to-body ratio, the better the visual effect. Therefore, the narrow frame and full-screen design have become the development trend. In order to increase the screen-to-body ratio of the electronic device 100, the width of the boss 1011 is made narrower and narrower, so that the width of the bearing surface 10111 for bonding the light-transmitting cover plate 21 on the boss 1011 becomes narrower and narrower. In this way, when dispensing glue on the bearing surface 10111, the colloid 1004 is likely to fall off from the bearing surface 10111, resulting in that the colloid 1004 is not easily evenly pressed open between the bearing surface 10111 and the light-transmitting cover plate 21, and there will be a sealing gap between the bearing surface 10111 and the light-transmitting cover plate 21, leading to sealing failure.

[0076] It can be understood that, please refer to Figure 4 , there will inevitably be a gap 1003 between the light-transmitting cover plate 21 of the display screen 2 and the frame part 101 of the housing 1. External grease and water stains (such as the user's sweat, etc.) are likely to accumulate in this gap 1003. At this time, the grease and water stains are likely to enter the inside of the display screen 2 through the sealing gap between the bearing surface 10111 and the light-transmitting cover plate 21 to erode the display screen 2. For example, the OCA glue (optical clear adhesive) between the light-transmitting cover plate 21 and the display module 22 will swell, resulting in yellow spots on the display screen 2 and affecting the display effect of the display screen 2.Figure 4 The arrow in the figure indicates the movement path of external grease and water stains entering the gap 1003 between the display screen 2 and the frame part 101, and entering the interior of the display screen 2 through the sealing gap between the light-transmitting cover plate and the bearing surface.

[0077] Meanwhile, in order to achieve an ultra-high screen-to-body ratio, the electronic device 100 usually adopts a narrow-gap sound conduction scheme. That is, in order to achieve the effect of sound conduction, a sound conduction gap 1001 is formed between the display screen 2 and the frame part 101. It can be that a sound conduction gap 1001 is formed between the top end of the display screen 2 (such as Figure 1 one end of the display screen 2 along the positive Y-axis direction in the figure) and the frame part 101, or it can be that a sound conduction gap 1001 is formed between the bottom end of the display screen 2 (such as Figure 1 one end of the display screen 2 along the negative Y-axis direction in the figure) and the frame part 101, or it can be that a sound conduction gap 1001 is formed between the left end of the display screen 2 (such as Figure 1 one end of the display screen 2 along the negative X-axis direction in the figure) and the frame part 101, or it can also be that a sound conduction gap 1001 is formed between the right end of the display screen 2 (such as Figure 1 one end of the display screen 2 along the positive X-axis direction in the figure) and the frame part 101.

[0078] Please refer back to Figure 1 In the electronic device 100, there is an audio device 5, and the sound conduction gap 1001 is used to communicate with the audio device 5. Among them, the audio device 5 can be a device that converts an audio electrical signal into a sound signal. Exemplarily, the audio device 5 can be a speaker or a receiver, etc.; the audio device 5 can also be a device that converts a sound signal into an electrical signal. Exemplarily, the audio device 5 can be a microphone, etc.; the audio device 5 can also be a device that simultaneously has the functions of converting an audio electrical signal into a sound signal and converting a sound signal into an audio electrical signal.

[0079] The sound conduction gap 1001 communicates with the audio device 5, so that the sound signal emitted by the audio device 5 can be transmitted from the inside of the electronic device 100 to the outside of the electronic device 100 for the user to receive. At this time, the sound conduction gap 1001 is an out-sound gap for sound output; or the external sound signal can be transmitted to the inside of the electronic device 100 through the sound conduction gap 1001 to be collected and received by the audio device 5. At this time, the sound conduction gap 1001 is a sound pickup port for sound collection.

[0080] Exemplarily, please refer to Figure 1 In the figure, the audio device 5 is a receiver, the sound conduction gap 1001 is an out-sound gap, and is provided at the top end of the display screen 2. Based on this, the electronic device 100 in the embodiment of the present application can be an electronic device 100 that uses a narrow gap for the receiver to output sound.

[0081] It can be understood that, in order to ensure normal sound transmission at the sound transmission gap 1001 of the electronic device 100, the bonding between the frame portion 101 at the sound transmission gap 1001 and the light-transmitting cover plate 21 cannot be carried out through the boss 1011 anymore, because this will block the communication channel between the audio device 5 and the sound transmission gap 1001 and prevent sound transmission.

[0082] Based on this, please refer to Figure 5 and Figure 6 in which Figure 5 is a partial structural schematic diagram of the housing 1 of the electronic device 100 provided in some embodiments of the present application. The boss 1011 has a sound transmission opening 10113, that is to say, the boss 1011 is disconnected at the part opposite to the sound transmission gap 1001 to form the sound transmission opening 10113. Please refer to Figure 6 and Figure 6 which is a cross-sectional view of the electronic device 100 provided in some embodiments of the present application along the Figure 1 B-B line in Figure 6 . When the light-transmitting cover plate 21 of the display screen 2 is bonded to the bearing surface 10111 of the boss 1011, a sound transmission channel 1002 communicating with the sound transmission gap 1001 is formed between the display screen 2, the sound transmission opening 10113 and the frame portion 101. In this way, the audio device 5 provided inside the electronic device 100 can communicate with the sound transmission gap 1001 through the sound transmission channel 1002. When the audio device 5 is a receiver, the sound signal emitted by the audio device 5 can be transmitted outwards along the Figure 6 straight arrow direction in

[0083] and received by the user. When the audio device 5 is a microphone, the external sound signal can be transmitted along the

[0084] curved arrow direction in

[0085] and received by the audio device 5 provided inside the electronic device 100.

[0084] Exemplarily, the sound transmission gap 1001 can be directly opposite to the sound transmission opening 10113, that is to say, the central axis of the sound transmission gap 1001 parallel to the bearing surface 10111 can overlap with the central axis of the sound transmission opening 10113 parallel to the bearing surface 10111. In this way, not only the structure of the electronic device 100 is symmetrical, which is convenient for production and processing, but also the sound transmission effect is good. Of course, the present application is not limited to this. In some other examples, the sound transmission gap 1001 and the sound transmission opening 10113 may not be directly opposite.

[0085] In addition, in some examples, the extension length of the sound conduction gap 1001 along the circumferential direction of the frame portion 101 may be greater than the extension length of the sound conduction opening 10113 along the circumferential direction of the frame portion 101; in some examples, the extension length of the sound conduction gap 1001 along the circumferential direction of the frame portion 101 may be less than the extension length of the sound conduction opening 10113 along the circumferential direction of the frame portion 101; in some examples, the extension length of the sound conduction gap 1001 along the circumferential direction of the frame portion 101 may be equal to the extension length of the sound conduction opening 10113 along the circumferential direction of the frame portion 101.

[0086] To solve the above technical problems, in some embodiments of the present application, please refer to Figure 7 and Figure 8 , where Figure 7 is a partial cross-sectional view of the electronic device 100 provided in some embodiments of the present application along the Figure 1 A-A line in Figure 8 is a partial structural schematic diagram of the housing 1 of the electronic device 100 provided in some embodiments of the present application. A diversion groove 10112 with an open front side is provided on the convex platform 1011. The diversion groove 10112 and the bearing surface 10111 are located on the same wall surface of the convex platform 1011. That is to say, the diversion groove 10112 is provided on the wall surface of the convex platform 1011 where the bearing surface 10111 is located. One end of the diversion groove 10112 penetrates the side wall surface of the convex platform 1011 facing the sound conduction opening 10113.

[0087] Specifically, please continue to refer to Figure 7 and Figure 8 , the bearing surface 10111 is located on the front wall surface of the convex platform 1011. That is to say, at least a part of the front wall surface of the convex platform 1011 constitutes the bearing surface 10111. The diversion groove 10112 is also provided on the front wall surface of the convex platform 1011. The diversion groove 10112 extends along the circumferential direction of the frame portion 101 on the front wall surface of the convex platform 1011. One end of the diversion groove 10112 in the circumferential direction extends towards the sound conduction opening 10113 and penetrates the side wall surface of the convex platform 1011 facing the sound conduction opening 10113. The other end of the diversion groove 10112 in the circumferential direction extends in a direction away from the sound conduction opening 10113. For the convenience of description, here one end of the diversion groove 10112 that penetrates the side wall surface of the convex platform 1011 facing the sound conduction opening 10113 is taken as the first end 10112a, and the end of the diversion groove 10112 away from the first end 10112a is taken as the second end 10112b.

[0088] It can be understood that after the transparent cover plate 21 of the display screen 2 is bonded to the bearing surface 10111, the gap 1003 between the transparent cover plate 21 and the frame portion 101 is directly opposite to the wall surface of the boss 1011 where the bearing surface 10111 is located in the front-to-back direction. Grease and water stains from the outside will accumulate on the wall surface of the boss 1011 where the bearing surface 10111 is located. By providing a guide groove 10112 on the wall surface of the boss 1011 where the bearing surface 10111 is located, a portion of the grease and water stains from the outside can directly enter and be collected in the guide groove 10112, and the other portion of the grease and water stains can first fall into other areas on the front wall surface of the boss 1011, and then flow from other areas to the guide groove 10112. It should be noted that the "other areas" mentioned here refer to the areas on the front wall surface of the boss 1011 except the areas where the guide groove 10112 are located. For example, the other areas may include the area where the bearing surface 10111 is located.

[0089] In this way, grease and water stains from the outside can fall onto the wall surface of the bearing surface 10111 of the boss 1011 through the gap 1003 between the transparent cover plate 21 and the frame portion 101, and then gather into the guide groove 10112. Since the first end 10112a of the guide groove 10112 passes through the side wall surface of the boss 1011 facing the sound-passing opening 10113, that is, the guide groove 10112 is connected with the sound-passing opening 10113 through its first end 10112a, the grease and water stains gathered in the guide groove 10112 can be promptly guided to the sound-passing opening 10113 through the first end 10112a of the guide groove 10112, thereby avoiding the accumulation of grease and water stains on the wall surface of the boss 1011 where the bearing surface 10111 is located, and further avoiding the grease and water stains from passing through the sealed gap between the bearing surface 10111 and the transparent cover plate 21 and entering the interior of the display screen 2 to erode the display screen 2.

[0090] In some embodiments of the present application, the guide groove 10112 is located on the side of the bearing surface 10111 facing the frame portion 101. In this way, the guide groove 10112 can be directly opposite the gap 1003 between the frame portion 101 and the light-transmitting cover plate 21, or relatively close to the gap 1003, which makes it easier for water stains and grease to enter the guide groove 10112, thereby allowing the water stains and grease to be more promptly guided out of the wall surface of the boss 1011 where the bearing surface 10111 is located. For example, please continue to refer to Figure 7 and Figure 8, the diversion groove 10112 is located on the side of the bearing surface 10111 facing the frame part 101. The diversion groove 10112 is arranged adjacent to the frame part 101. That is to say, at least part of the structure of the frame part 101 constitutes the groove side wall of the diversion groove 10112. In this way, the diversion groove 10112 can face the gap 1003 between the frame part 101 and the light-transmitting cover plate 21, and water stains and grease are more likely to enter the diversion groove 10112. In some other examples, there may also be a gap between the diversion groove 10112 and the frame part 101.

[0091] Further, please refer to Figure 9 , Figure 9 is Figure 8 the projection of the diversion groove 10112 shown in in the plane of the inner wall surface of the frame part 101. One end of the through boss 1011 of the diversion groove 10112 facing the side wall surface of the sound transmission opening 10113 is the first end 10112a, and the end of the diversion groove 10112 far from the first end 10112a is the second end 10112b. In the direction from the second end 10112b of the diversion groove 10112 towards the first end 10112a of the diversion groove 10112, the bottom wall 10112c of the diversion groove 10112 extends obliquely in the direction away from the front side.

[0092] It can be understood that when the electronic device 100 is in a non-use state, according to the user's habit, when placing the electronic device 100, generally, the side where the display screen 2 of the electronic device 100 is located is placed facing away from the bearing platform (such as a desktop, etc.) of the electronic device 100. That is to say, the front side of the electronic device 100 is placed facing away from the bearing platform, and the rear side of the electronic device 100 faces the bearing platform. The direction from the front to the rear of the electronic device 100 is consistent with the gravity direction of the grease and water stains. By making the bottom wall 10112c of the diversion groove 10112 extend in the direction away from the front side in the direction from the second end 10112b of the diversion groove 10112 towards the first end 10112a of the diversion groove 10112, so that in the direction from the second end 10112b towards the first end 10112a, the bottom wall 10112c of the diversion groove 10112 extends obliquely along the gravity direction of the grease and water stains. Thus, the grease and water stains collected in the diversion groove 10112 can flow from the second end 10112b to the first end 10112a more quickly and smoothly, and then be guided to the sound transmission opening 10113 by the first end 10112a.

[0093] Further, please continue to refer to Figure 9, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a is greater than or equal to 0.3 mm. Exemplarily, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a can be 0.30 mm, 0.35 mm, 0.40 mm, 0.45 mm, 0.50 mm, 0.55 mm, 0.60 mm, 0.65 mm, 0.70 mm, 0.75 mm, 0.80 mm, 0.90 mm, 0.95 mm, 1.00 mm, 1.20 mm, 1.30 mm, 1.40 mm, or 1.50 mm, etc.

[0094] It can be understood that on the premise that the extension length of the diversion groove 10112 along the circumferential direction of the frame portion 101 is certain, the greater the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a of the diversion groove 10112, the greater the inclination angle of the bottom wall 10112c of the diversion groove 10112, and the better the guiding effect on grease and water stains. By making the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a greater than or equal to 0.3 mm, the bottom wall 10112c of the diversion groove 10112 has a larger inclination angle, so that the guiding effect of the diversion groove 10112 on grease and water stains is better, and the grease and water stains in the diversion groove 10112 can be guided to the sound passage opening 10113 more quickly and smoothly.

[0095] Optionally, the height difference ΔH between the bottom wall 10112c of the second end 10112b and the bottom wall 10112c of the first end 10112a is less than or equal to 1.5 mm. That is to say, while ensuring that the bottom wall 10112c of the diversion groove 10112 has a certain inclination angle to improve the guiding effect, the inclination angle cannot be made too large, which will affect the connection strength between the boss 1011 and the frame portion 101. In addition, too large an inclination angle will increase the difficulty of molding the housing 1.

[0096] In some embodiments of the present application, please refer back to Figure 8 , the frame portion 101 is provided with a sound passage opening 1012, and the sound passage opening 1012 is communicated with the sound passage opening 10113. Specifically, the part of the frame portion 101 where the sound passage opening 10113 is located is provided with a sound passage opening 1012, and the sound passage opening 1012 is also used for sound communication between the audio device 5 and the outside. The sound passage opening 1012 can be used for sound output or sound pickup. By providing the sound passage opening 1012 in the frame portion 101, the audio device 5 can communicate with the outside not only through the sound passage gap 1001 provided between the frame portion 101 and the display screen 2, but also through the sound passage opening 1012.

[0097] Both the sound passage opening 1012 and the sound passage gap 1001 are in communication with the sound passage 1002. By providing the sound passage opening 1012, the total sound passage area is increased. In this way, the airflow in the sound passage 1002 can be balanced, thereby avoiding the problem of noise in the sound passage caused by a large airflow in the sound passage 1002 due to the small cross-sectional area of the sound passage 1002.

[0098] In addition, by providing the sound passage opening 1012 in a part of the frame portion 101 where the sound passage opening 10113 is located, the grease and water stains guided to the sound passage opening 10113 can be discharged to the outside of the housing 1 through the sound passage opening 1012, preventing them from accumulating inside the housing 1 and eroding other components within the electronic device 100, thereby further improving the reliability of the electronic device 100 and extending the service life of the electronic device 100.

[0099] Furthermore, it can be understood that the electronic device 100 adopts a narrow-slit sound passage solution, and there is a sound passage gap 1001 for sound passage between the display screen 2 and the frame portion 101. During the use of the electronic device 100, external grease and water stains can also directly enter the interior of the electronic device 100 through the sound passage gap 1001. In this way, not only the grease and water stains guided by the diversion groove 10112 will accumulate at the sound passage opening 10113, but also the grease and water stains directly entering the interior of the electronic device 100 through the sound passage gap 1001 will accumulate. By providing the sound passage opening 1012 in a part of the frame portion 101 where the sound passage opening 10113 is located, not only can the grease and water stains guided by the diversion groove 10112 to the sound passage opening 10113 be discharged to the outside of the housing 1, but also the grease and water stains entering the electronic device 100 through the sound passage gap 1001 can be guided to the outside of the housing 1.

[0100] The sound passage opening 1012 can be a single-hole structure or a multi-hole structure. Exemplarily, please continue to refer to Figure 8 , there are multiple sound passage openings 1012, and the multiple sound passage openings 1012 are sequentially spaced apart along the circumferential direction of the frame portion 101. The shape of the sound passage opening 1012 can be arbitrarily selected according to needs. Exemplarily, the sound passage opening 1012 can be circular, elliptical, or polygonal, etc.

[0101] In some embodiments of the present application, please continue to refer to Figure 8 and in combination with reference to Figure 6, the housing 1 of the electronic device 100 further includes a middle plate portion 102. The frame portion 101 is disposed around the edge of the middle plate portion 102. The boss 1011 is located on the front side of the middle plate portion 102. When the display screen 2 is bonded to the bearing surface 10111 of the boss 1011, the display screen 2 is located on the front side of the middle plate portion 102, and the display module 22 is located in the accommodation space formed by the light-transmitting cover plate 21, the frame portion 101, and the front side wall of the middle plate portion 102.

[0102] The middle plate portion 102 is provided with a sound passage groove 1021 that is open at the front side. The sound passage groove 1021 communicates with the sound passage opening 10113. The bottom wall of the sound passage groove 1021 is provided with an opening 10213a for communicating with the audio device 5. The audio device 5 is disposed on the back side of the middle plate portion 102, that is, the audio device 5 is disposed on the side of the middle plate portion 102 away from the display screen 2. The audio device 5 is opposite to the opening 10213a to ensure that the audio device 5 communicates with the outside through the opening 10213a, the sound passage opening 10113, and the sound passage gap 1001.

[0103] It can be understood that a part of the communication channel between the audio device 5 and the sound passage gap 1001 is located between the display module 22 and the middle plate portion 102. The gap between the display module 22 and the middle plate portion 102 directly affects the sound passage area of the communication channel. By providing the sound passage groove 1021 that is open at the front side on the middle plate portion 102, and the bottom wall of the sound passage groove 1021 is provided with the opening 10213a communicating with the audio device 5, the communication channel located between the display module 22 and the middle plate portion 102 is formed between the display module 22 and the sound passage groove 1021. That is, the space enclosed between the display module 22 and the sound passage groove 1021 constitutes a part of the communication channel. In this way, the cross-sectional area of the communication channel can be increased without increasing the overall gap between the display module 22 and the middle plate portion 102, which is beneficial to the thinning of the electronic device 100.

[0104] Further, please continue to refer to Figure 6 and Figure 8 , the sound passage groove 1021 is provided with a rib 10211 to divide the sound passage groove 1021 into a first sound passage groove portion 10212 and a second sound passage groove portion 10213. The second sound passage groove portion 10213 is located on the side of the first sound passage groove portion 10212 away from the sound passage opening 10113. Exemplarily, please refer to Figure 6 and Figure 8 , the first sound passage groove portion 10212 and the second sound passage groove portion 10213 are arranged in the direction of the Y axis. The second sound passage groove portion 10213 is located on the side of the first sound passage groove portion 10212 along the negative Y axis. Compared with the second sound passage groove portion 10213, the first sound passage groove portion 10212 is closer to the sound passage opening 10113. The opening 10213a is provided on the bottom wall of the second sound passage groove portion 10213.

[0105] In this way, the grease and water stains guided by the diversion groove 10112 to the sound conduction opening 10113, as well as the grease and water stains entering the interior of the electronic device 100 through the sound conduction gap 1001, can be collected in the first sound conduction groove portion 10212, which can prevent the grease and water stains guided by the diversion groove 10112 to the sound conduction opening 10113 and the grease and water stains entering the interior of the electronic device 100 through the sound conduction gap 1001 from spreading wantonly inside the electronic device 100 and eroding other components inside the electronic device 100.

[0106] In addition, the first sound conduction groove portion 10212 and the second sound conduction groove portion 10213 are spaced apart by the rib 10211, and the first sound conduction groove portion 10212 and the second sound conduction groove portion 10213 are not communicated with each other. In this way, the grease and water stains collected in the first sound conduction groove portion 10212 will not enter the second sound conduction groove portion 10213, thereby preventing the grease and water stains from eroding the audio device 5 through the opening 10213a.

[0107] On the above basis, please continue to refer to Figure 6 and Figure 8 , the sound conduction opening 1012 provided on the frame portion 101 is communicated with the first sound conduction groove portion 10212. In this way, the grease and water stains collected in the first sound conduction groove portion 10212 can be discharged to the outside of the electronic device 100 through the sound conduction opening 1012.

[0108] Furthermore, please continue to refer to Figure 6 and Figure 8 , the part of the frame portion 101 where the sound conduction opening 10113 is located constitutes a part of the groove side wall of the first sound conduction groove portion 10212, and the sound conduction opening 1012 is located on the groove side wall of the first sound conduction groove portion 10212. That is to say, the part of the frame portion 101 where the sound conduction opening 1012 is located constitutes a part of the groove side wall of the first sound conduction groove portion 10212, and the sound conduction opening 1012 is exactly located on this part of the groove side wall. In this way, the sound conduction opening 1012 can be directly communicated with the first sound conduction groove portion 10212, thereby simplifying the overall structure of the housing 1.

[0109] In addition, by making the part of the frame portion 101 where the sound conduction opening 10113 is located constitute a part of the groove side wall of the first sound conduction groove portion 10212, in this way, the first sound conduction groove portion 10212 can be closely attached to the frame portion 101 where the sound conduction opening 10113 is located, and the grease and water stains in the area of the frame portion 101 where the sound conduction opening 10113 is located can directly flow into the first sound conduction groove portion 10212, thereby better preventing the grease and water stains from eroding other components inside the electronic device 100.

[0110] Of course, the present application is not limited thereto. In some other embodiments, the frame portion 101 where the sound passage opening 10113 is located does not form the groove side wall of the first sound passage groove portion 10212, and the sound passage port 1012 is indirectly communicated with the first sound passage groove portion 10212.

[0111] Please continue to refer to Figure 6 and Figure 8 , the front edge of the convex rib 10211 is located behind the front edge of the sound passage groove 1021. In this way, the gap between the front edge of the convex rib 10211 and the display module 22 is greater than the gap between the front edge of the sound passage groove 1021 and the display module 22. Thereby, it is possible to avoid affecting the cross-sectional area of the communication channel between the audio device 5 and the sound passage gap 1001 due to the setting of the convex rib 10211, and ensure normal sound passage between the audio device 5 and the outside.

[0112] Please refer to Figure 8 , a plurality of protrusions 10212a arranged in an array are provided on the bottom wall of the first sound passage groove portion 10212. By providing a plurality of protrusions 10212a arranged in an array, the water droplet angle between the grease and water stains and the bottom wall of the first sound passage groove portion 10212 can be increased, and the grease and water stains can be better aggregated in the first sound passage groove portion 10212, so as to facilitate the discharge of the grease and water stains to the outside of the electronic device 100 through the sound passage port 1012.

[0113] Among them, the protrusions 10212a can be formed on the bottom wall of the first sound passage groove portion 10212 by a laser engraving process. In this way, not only the processing technology is simple and the cost is low, but also the surface roughness of the protrusions 10212a processed by the laser engraving process is relatively high. Thereby, the water droplet angle between the grease and water stains and the bottom wall of the first sound passage groove portion 10212 is larger, and the first sound passage groove portion 10212 has a better effect of collecting the grease and water stains.

[0114] Of course, the present application is not limited thereto. The protrusions 10212a can also be integrally formed on the bottom wall of the first sound passage groove portion 10212 by an injection molding process; or the protrusions 10212a can be separately formed and then fixed on the bottom wall of the first sound passage groove portion 10212 by bonding or welding and other processes.

[0115] It can be understood that the arrangement manner of the plurality of protrusions 10212a on the bottom wall of the first sound passage groove portion 10212 is not limited to the above-mentioned array arrangement, and its arrangement manner can be arbitrarily selected according to needs. In some other examples, the plurality of protrusions 10212a on the bottom wall of the first sound passage groove portion 10212 can also be arranged in an annular array.

[0116] Please continue to refer to Figure 8, the projection of the edge of the first end 10112a of the diversion groove 10112 on the front wall surface of the middle plate portion 102 overlaps with the projection of the edge of the first sound conduction groove portion 10212 on the front wall surface of the middle plate portion 102. In this way, when the grease and water stains in the diversion groove 10112 are guided from the first end 10112a towards the sound conduction opening 10113, the grease and water stains can be directly guided into the first sound conduction groove portion 10212 along the side wall surface of the boss 1011, without flowing to other areas on the middle plate portion 102, thereby better avoiding the erosion of other components in the electronic device 100 by the grease and water stains.

[0117] In some other embodiments, the projection of the edge of the first end 10112a of the diversion groove 10112 on the front wall surface of the middle plate portion 102 is located within the projection area of the first sound conduction groove portion 10212 on the front wall surface of the middle plate portion 102. Similarly, when the grease and water stains in the diversion groove 10112 are guided from the first end 10112a towards the sound conduction opening 10113, the grease and water stains can be directly guided into the first sound conduction groove portion 10212 along the side wall surface of the boss 1011, without flowing to other areas on the middle plate portion 102, thereby better avoiding the erosion of other components in the electronic device 100 by the grease and water stains.

[0118] Please refer to Figure 10 , Figure 10 For Figure 8 is a partially enlarged view of the housing 1 in

[0119] Exemplarily, please continue to refer to Figure 10 , one end of the bearing surface 10111 facing the sound conduction opening 10113 has a first guiding section surface 1015, and the width of the first guiding section surface 1015 gradually decreases in the direction towards the sound conduction opening 10113. In this way, the first guiding section surface 1015 has the function of guiding the grease and water stains towards the sound conduction opening 10113, and the grease and water stains on the bearing surface 10111 can be smoothly and quickly guided to the sound conduction opening 10113 through the first guiding section surface 1015, avoiding the accumulation of grease and water stains on the bearing surface 10111 and entering the display screen 2 to erode the display screen 2.

[0120] Of course, the present application is not limited to this. The edge of the first guiding section surface 1015 facing the sound conduction opening 10113 can also be composed of multiple straight line segments. Exemplarily, please refer to [[ID=2)) Figure 11 , Figure 11A partial enlarged view of the housing 1 of the electronic device 100 provided by some embodiments of the present application. The edge of the first guiding section 1015 facing the sound passage opening 10113 includes a first straight section 10151 and a second straight section 10152. In the direction facing the sound passage opening 10113, the first straight section 10151 and the second straight section 10152 extend towards each other until they intersect, and at this time, the first guiding section 1015 can be formed into a triangle.

[0121] Similarly, please refer back to Figure 10 , one end of the diversion groove 10112 facing the sound passage opening 10113 has a second guiding section 1016, and the width of the second guiding section 1016 gradually decreases in the direction facing the sound passage opening 10113. In this way, the second guiding section 1016 has the function of guiding grease and water stains towards the sound passage opening 10113, and the grease and water stains in the diversion groove 10112 can be smoothly and quickly guided to the sound passage opening 10113 through the second guiding section 1016, avoiding the accumulation of grease and water stains in the diversion groove 10112.

[0122] Exemplarily, please continue to refer to Figure 10 , the edge of the second guiding section 1016 facing the sound passage opening 10113 is an arc protruding towards the sound passage opening 10113, and at this time, the second guiding section 1016 can be formed into a semi-circle. In this way, the edge of the second guiding section 1016 facing the sound passage opening 10113 is relatively smooth, and the structure is beautiful and convenient for processing.

[0123] Of course, the present application is not limited to this. The edge of the second guiding section 1016 facing the sound passage opening 10113 can also be composed of multiple straight sections. Exemplarily, please refer to Figure 11 , the edge of the second guiding section 1016 facing the sound passage opening 10113 includes a third straight section 10161 and a fourth straight section 10162. In the direction facing the sound passage opening 10113, the third straight section 10161 and the fourth straight section 10162 extend towards each other until they intersect, and at this time, the second guiding section 1016 can be formed into a triangle.

[0124] In some other examples, only the bearing surface 10111 is provided with the above-mentioned first guiding section 1015, and the diversion groove 10112 is not provided with the above-mentioned second guiding section 1016.

[0125] In some other examples, the above-mentioned first guiding section 1015 is not provided on the bearing surface 10111, and only the diversion groove 10112 is provided with the above-mentioned second guiding section 1016.

[0126] In some embodiments of the present application, please refer to Figure 12 andFigure 13 , wherein, Figure 12 is a partial structural schematic diagram of the housing 1 of the electronic device 100 provided in some embodiments of the present application. Figure 13 is Figure 12 a partial structural schematic diagram of the housing 1 shown in [reference] from another angle. The width of the side wall surface of the boss 1011 facing the sound passage opening 10113 gradually decreases in the front-to-back direction. It can be understood that the grease and water stains in the diversion groove 10112 and on the bearing surface 10111 will flow along the side wall surface of the boss 1011 facing the sound passage opening 10113 into the first sound passage groove portion 10212. By making the width of the side wall surface of the boss 1011 facing the sound passage opening 10113 gradually decrease in the front-to-back direction, the side wall surface of the boss 1011 facing the sound passage opening 10113 has a guiding function, so that the grease and water stains in the diversion groove 10112 and on the bearing surface 10111 can be guided into the first sound passage groove portion 10212 more quickly and smoothly. Exemplarily, please refer to Figure 13 , the side wall surface of the boss 1011 facing the sound passage opening 10113 can be formed into an inverted triangular structure.

[0127] Please continue to refer to Figure 13 , a first arc transition surface 1013 is provided between the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bearing surface 10111, and a second arc transition surface 1014 is provided between the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bottom wall 10112c of the diversion groove 10112. By providing the first arc transition surface 1013, a smooth transition can be achieved between the bearing surface 10111 and the side wall surface of the boss 1011 facing the sound passage opening 10113, so that the grease and water stains on the bearing surface 10111 can be guided more smoothly to the side wall surface of the boss 1011 facing the sound passage opening 10113 through the first arc transition surface 1013. Similarly, by providing the second arc transition surface 1014, a smooth transition can be achieved between the bottom wall 10112c of the diversion groove 10112 and the side wall surface of the boss 1011 facing the sound passage opening 10113, so that the grease and water stains in the diversion groove 10112 can be guided more smoothly to the side wall surface of the boss 1011 facing the sound passage opening 10113 through the second arc transition surface 1014.

[0128] Exemplarily, please refer to Figure 13 , both the first arc transition surface 1013 and the second arc transition surface 1014 are formed into arc surface structures protruding towards the light-transmitting cover plate 21. Of course, the present application is not limited thereto. In another example, please refer to Figure 14 , Figure 14A partial enlarged view of the housing 1 of the electronic device 100 provided in some embodiments of the present application. The first arc transition surface 1013 and the second arc transition surface 1014 may also be formed as arc surface structures protruding in a direction away from the light-transmitting cover plate 21.

[0129] Or refer to Figure 15 , Figure 15 A partial enlarged view of the housing 1 of the electronic device 100 provided in some embodiments of the present application. The first arc transition surface 1013 includes a first sub-transition surface 10131 and a second sub-transition surface 10132 connected to each other. The first sub-transition surface 10131 is formed as an arc surface structure protruding in a direction towards the light-transmitting cover plate 21, and the second sub-transition surface 10132 is formed as an arc surface structure protruding in a direction away from the light-transmitting cover plate 21. In this way, the overall length of the first arc transition surface 1013 can be increased, and its guiding effect on grease and water stains is better. In some other examples, the first sub-transition surface 10131 may also be formed as an arc surface structure protruding in a direction away from the light-transmitting cover plate 21, and the second sub-transition surface 10132 may be formed as an arc surface structure protruding in a direction towards the light-transmitting cover plate 21.

[0130] Similarly, please continue to refer to Figure 15 , the second arc transition surface 1014 includes a third sub-transition surface 10141 and a fourth sub-transition surface 10142 connected to each other. The third sub-transition surface 10141 is formed as an arc surface structure protruding in a direction towards the light-transmitting cover plate 21, and the fourth sub-transition surface 10142 is formed as an arc surface structure protruding in a direction away from the light-transmitting cover plate 21. In this way, the overall length of the second arc transition surface 1014 can be increased, and its guiding effect on grease and water stains is better. In some other examples, the third sub-transition surface 10141 may also be formed as an arc surface structure protruding in a direction away from the light-transmitting cover plate 21, and the fourth sub-transition surface 10142 may be formed as an arc surface structure protruding in a direction towards the light-transmitting cover plate 21.

[0131] In some other embodiments, only the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bearing surface 10111 are provided with the above-mentioned first arc transition surface 1013, and the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bottom wall 10112c of the diversion groove 10112 are not provided with the above-mentioned second arc transition surface 1014.

[0132] In another embodiment, only the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bottom wall 10112c of the diversion groove 10112 are provided with the above-mentioned second arc transition surface 1014, and the side wall surface of the boss 1011 facing the sound passage opening 10113 and the bearing surface 10111 are not provided with the above-mentioned first arc transition surface 1013.

[0133] Please refer to Figures 13 - 15, the inner wall surface of the boss 1011 extends obliquely in a direction approaching the frame portion 101 in the front-to-back direction. That is to say, the cross-sectional area of the boss 1011 in the plane parallel to the bearing surface 10111 gradually decreases in the front-to-back direction. In this way, while reducing the space occupied by the boss 1011 inside the housing 1, it can ensure that the front wall surface of the boss 1011 has a larger area, so as to ensure the area of the bearing surface 10111 on the front wall surface of the boss 1011, and further ensure the reliability of the connection between the light-transmitting cover plate 21 and the bearing surface 10111. In addition, by reducing the space occupied by the boss 1011 inside the housing 1, the utilization rate of the internal space of the housing 1 can be improved.

[0134] In some examples, the boss 1011 and the frame portion 101 are integrally formed parts. That is to say, the boss 1011 and the frame portion 101 are processed integrally. In this way, the connection strength between the boss 1011 and the frame portion 101 is high, and the processing technology is simple. In some other examples, the boss 1011 and the frame portion 101 can also be split structural parts. After the boss 1011 is separately formed, it is connected to the frame portion 101 through connection methods such as bonding, welding or threaded connection.

[0135] It can be understood that since the electronic device 100 adopts the sound conduction method of narrow slit sound conduction, during the use of the electronic device 100, water stains such as the user's sweat and moisture in the external environment, as well as grease, are likely to enter the inside of the electronic device 100 through the sound conduction gap 1001. The water stains and grease can be transmitted to the display module 22, and the display module 22 includes a plurality of sub-functional layers, and the plurality of sub-functional layers are stacked. Therefore, the circumferential side surface of the display module 22 is composed of the circumferential side surfaces of the plurality of sub-functional layers. The water stains and grease transmitted to the circumferential side surface of the display module 22 are likely to enter the inside of the display module 22 through the gaps between adjacent sub-functional layers, thereby affecting the normal operation of the display module 22.

[0136] Based on this, in order to prevent the circumferential side surface of the display module 22 from being eroded by water stains and grease, please refer to Figure 16 and Figure 17 , where Figure 16 is a partial structural schematic diagram of the electronic device 100 at the sound conduction gap 1001 in some embodiments of the present application. The display screen 2 and the sound conduction groove 1021 are not shown in the figure; Figure 17 is a partial cross-sectional view of the electronic device 100 along the Figure 16 C-C line in some embodiments of the present application. A side sealant 6 is provided on at least the circumferential side surface of the display module 22 facing the sound conduction gap 1001. By providing the side sealant 6, the gaps between adjacent sub-functional layers can be sealed, so as to prevent water stains and grease from entering the inside of the display module 22.

[0137] Optionally, the side sealant 6 is opposite to the sound conduction gap 1001, and the circumferential extension length of the side sealant 6 is greater than the circumferential extension length of the sound conduction gap 1001. The two circumferential ends of the side sealant 6 respectively extend to the inner sides of the inner wall surfaces of the bosses 1011 located on both sides of the sound conduction opening 10113. In this way, the side sealant 6 has better sealing performance for the circumferential side surface of the display module 22 opposite to the sound conduction gap 1001.

[0138] To avoid the side sealant 6, please refer to Figure 16 and in combination with Figure 12 , the boss 1011 includes a main body section 1017 and an avoidance section 1018. The avoidance section 1018 is connected to the main body section 1017 and extends to the sound conduction opening 10113. The inner wall surface of the avoidance section 1018 is closer to the frame portion 101 than the inner wall surface of the main body section 1017. By making the inner wall surface of the avoidance section 1018 closer to the frame portion 101, the avoidance section 1018 has an avoidance effect on the side sealant 6, and the avoidance section 1018 creates a receiving space for the side sealant 6. The circumferential ends of the side sealant 6 extend to the inner sides of the inner wall surfaces of the avoidance section 1018, rather than extending to the inner sides of the inner wall surfaces of the main body section 1017.

[0139] It can be understood that the width of the bearing surface 10111 on the avoidance section 1018 is obviously smaller than the width of the bearing surface 10111 on the main body section 1017. In this way, it is more difficult to apply glue to the bearing surface 10111 of the avoidance section 1018, and the glue 1004 is likely to fall off from the bearing surface 10111 of the avoidance section 1018. It is more difficult to evenly press open the glue 1004 between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21, and there is a greater possibility of a sealing gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21. That is to say, there is a greater risk that the grease and water stains accumulated in the gap 1003 between the light-transmitting cover plate 21 and the frame portion 101 enter the inside of the display screen 2 through the sealing gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21.

[0140] Therefore, please continue to refer to Figure 16 , at least the avoidance section 1018 of the boss 1011 is provided with a diversion groove 10112. Further, the length of the diversion groove 10112 extending along the circumferential direction of the frame portion 101 is greater than or equal to the length of the avoidance section 1018 extending along the circumferential direction of the frame portion 101. In this way, it can be ensured that the grease and water stains on the wall surface of the boss 1011 where the bearing surface 10111 of the avoidance section 1018 is located can be timely guided to the sound conduction opening 10113 through the diversion groove 10112, thereby avoiding the grease and water stains accumulated in the gap 1003 between the light-transmitting cover plate 21 and the frame portion 101 from entering the inside of the display screen 2 through the sealing gap between the bearing surface 10111 of the avoidance section 1018 and the light-transmitting cover plate 21 to erode the display screen 2.

[0141] Please continue to refer to Figure 16 , a transition section 1019 is provided between the main body section 1017 and the avoidance section 1018. In the direction from the main body section 1017 towards the avoidance section 1018, the inner wall surface of the transition section 1019 extends obliquely towards the direction close to the frame portion 101. The inner wall surface of the transition section 1019 can be formed as an arc surface or a flat surface. By providing the transition section 1019 between the main body section 1017 and the avoidance section 1018, it is possible to avoid excessive dimensional changes in the bearing surfaces 10111 of the main body section 1017 and the avoidance section 1018 at the connection between the main body section 1017 and the avoidance section 1018, and it is not easy to apply glue at this connection. In addition, by providing the transition section 1019 between the main body section 1017 and the avoidance section 1018, the connection strength between the main body section 1017 and the avoidance section 1018 can also be improved.

[0142] Please refer to Figures 16 - 17 , a dam glue 7 is provided between the inner wall surface of the boss 1011 and the display module 22. One end of the dam glue 7 is connected to the circumferential end of the side seal glue 6, and the other end of the dam glue 7 extends in the direction away from the side seal glue 6. One end of the dam glue 7 can extend to the inside of the inner wall surface of the avoidance section 1018, and the other end of the dam glue 7 can extend to the inside of the inner wall surface of the main body section 1017.

[0143] By providing the dam glue 7 connected to the side seal glue 6 between the inner wall surface of the boss 1011 and the display module 22, a sealing structure is formed at the connection between the side seal glue 6 and the dam glue 7, and grease and water stains cannot enter the interior of the electronic device 100 through the connection between the side seal glue 6 and the dam glue 7, thereby providing better protection for the electronic device 100. Exemplarily, the side seal glue 6 and the dam glue 7 can be hot melt adhesives.

[0144] In addition, the electronic device 100 generally can also be provided with a camera assembly. Exemplarily, a front camera assembly is generally provided at a position of the electronic device 100 close to the sound transmission gap 1001. In order to prevent external grease or water stains from eroding the front camera assembly, a foam 8 is generally provided on the outer periphery of the front camera assembly. Please continue to refer to Figures 16 - , the foam 8 is provided between the display module 22 and the middle plate portion 102 and surrounds the outer periphery of the front camera assembly (not shown in the figure). By providing the foam 8, it is possible to prevent the grease and water stains entering the interior of the electronic device 100 from the sound transmission gap 1001 from eroding the front camera assembly.

[0145] The foam 8 can be a closed-cell foam, a semi-closed-cell foam or an open-cell foam, and the embodiments of the present application do not limit this. Among them, the closed-cell foam and the semi-closed-cell foam have strong resilience and holding force.
