Description

Technical Field

[0001] The present application belongs to the field of terminal technology, and specifically relates to a housing assembly and an electronic device. Background Art

[0002] Usually, an earpiece is provided inside the electronic device, and a sound outlet is provided between the display screen on the upper part of the electronic device and the frame of the housing, and the sound outlet is connected to the earpiece through a sound outlet channel. Therefore, when the user uses the electronic device to make a call, the user can put the ear close to the sound outlet, so that the sound emitted by the earpiece can be transmitted to the ear through the sound outlet channel and the sound outlet, and then the user can hear the sound emitted by the earpiece.

[0003] However, since the sound outlet may be clogged with dust, the sound from the earpiece may not be transmitted to the user's ear through the sound outlet channel and the sound outlet. As a result, the user cannot use the electronic device to make calls, thus affecting the convenience of using the electronic device. Summary of the invention

[0004] The present application aims to provide a housing assembly and an electronic device, which at least solves one of the problems of poor usability of the electronic device.

[0005] In the first aspect, an embodiment of the present application proposes a shell assembly, comprising: a shell, in which a sound producing unit, a first antenna and a second antenna are arranged, and a first break exists between the first antenna and the second antenna; a display screen is arranged on the shell, and a first sound outlet is formed by a gap between the display screen and the frame of the shell; a sound outlet channel is arranged between the shell and the display screen, and is connected with the sound producing unit and the first sound outlet; a second sound outlet is arranged on the frame of the shell, and is connected with the sound outlet channel, and the second sound outlet at least partially overlaps with the projection of the first break on the frame of the shell.

[0006] In a second aspect, an embodiment of the present application provides an electronic device, comprising: a housing assembly as described in the first aspect.

[0007] In an embodiment of the present application, a shell is provided with a sound unit, a first antenna and a second antenna, and a first break is provided between the first antenna and the second antenna; a display screen is provided on the shell, and a first sound outlet is formed by a gap between the display screen and the frame of the shell; a sound outlet channel is provided between the shell and the display screen, and is connected to the sound unit and the first sound outlet; a second sound outlet is provided on the frame of the shell, and is connected to the sound outlet channel, and the second sound outlet and the projection of the first break on the frame of the shell at least partially overlap. On the one hand, since the shell assembly is provided with the first sound outlet and the second sound outlet, that is, the shell assembly is provided with a plurality of sound outlets, in the case that one of the first sound outlet and the second sound outlet is blocked by dust, the other sound outlet may not be blocked by dust. Therefore, when the user is talking, the sound emitted by the sound unit can still be transmitted to the ear through the sound outlet channel and the other sound outlet, so that when the shell assembly is provided in the electronic device, the situation that the user cannot use the electronic device to talk can be reduced, thereby improving the convenience of using the electronic device. On the other hand, since the projections of the second sound outlet and the first cutout on the frame of the shell at least partially overlap, in this way, when the shell is integrally injection-molded, a space will be reserved for the second sound outlet at the first cutout during the injection molding of the shell, so that the volume of plastic that enters the first cutout during the injection molding can be reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first cutout on the frame of the shell after injection molding can be reduced, thereby avoiding shrinkage at this position during injection molding, thereby avoiding shrinkage marks at this position. In this way, the convenience of use of the electronic device can be improved while avoiding shrinkage marks on the shell.

[0008] In an embodiment of the present application, an electronic device may include the above-mentioned housing assembly. On the one hand, since the housing assembly of the electronic device is provided with a first sound outlet and a second sound outlet, that is, the housing assembly is provided with a plurality of sound outlets, in the case where one of the first sound outlet and the second sound outlet is blocked by dust, the other sound outlet may not be blocked by dust. Therefore, when the user is making a call, the sound emitted by the pronunciation unit of the electronic device can still be transmitted to the ear through the sound outlet channel and the other sound outlet, thereby reducing the situation where the user cannot use the electronic device to make a call, thereby improving the convenience of using the electronic device. On the other hand, since the projection of the second sound outlet and the first break on the frame of the housing at least partially overlaps, in this way, when the housing is integrally injection molded, a space will be reserved for the second sound outlet at the first break when the housing is injection molded, so that the volume of the plastic entering the first break during injection molding can be reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first break on the frame of the housing can be reduced, thereby avoiding the shrinkage of the position during injection molding, thereby avoiding the shrinkage mark at the position. In this way, the convenience of using the electronic device can be improved while avoiding the occurrence of shrinkage marks on the shell. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0024] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0025] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0026] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] The terms "at least one (item)", "at least one of" and the like in the specification and claims of the present application refer to any one, any two or a combination of more than two of the objects included therein. For example, at least one (item) of a, b, and c can be represented by: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", where a, b, and c can be single or multiple. Similarly, "at least two (items)" refers to two or more, and its meaning is similar to that of "at least one (item)".

[0028] The housing assembly and the electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0029] Generally, in related technologies, such as Figure 1A and Figure 1B As shown, a handset 1 is provided inside the electronic device, and a sound outlet 4 is provided between a display screen 2 and a housing 3 on the upper part of the electronic device, and the sound outlet 4 and the handset 1 are connected through a sound outlet channel 5. Thus, when a user uses the electronic device to make a call, the user can hold the lower part of the electronic device with his hand and put his ear close to the sound outlet 4 on the upper part of the electronic device, so that the sound emitted by the handset 1 can be transmitted to the ear through the sound outlet channel 5 and the sound outlet 4. For example, the sound emitted by the handset 1 can be transmitted along the sound outlet channel 5. Figure 1AThe direction indicated by the middle arrow is transmitted to the ear through the sound outlet channel 5 and the sound outlet hole 4, so that the user can hear the sound emitted by the earpiece 1. However, the applicant found in the actual application process that when the user puts the electronic device still somewhere, the display screen 2 of the electronic device is usually placed upward, that is, the sound outlet hole 4 is placed upward, which may cause dust to enter the sound outlet hole 4. In this way, when the user uses the electronic device to make a call, the sweat in the ear may be mixed with the dust and blocked in the sound outlet hole 4, which may cause the sound emitted by the earpiece 1 to be unable to pass through the sound outlet channel 5 and the sound outlet hole 4 to the user's ear, thereby causing the user to be unable to use the electronic device to make a call. In addition, in order to meet the performance of each frequency band of the electronic device antenna, metal antennas of different lengths will be designed in the frame of the shell 3 wrapped in the surface plastic, and the lengths of the metal antennas of different frequency bands are different, and different metal antennas are separated by fractures of different widths, so that the performance of the metal antenna is easier to meet the needs. However, the applicant has found in actual applications that antenna cutouts of different widths will lead to uneven thickness of the plastic wall of the shell 3 during the injection molding process, which may cause obvious shrinkage marks 6 on the surface plastic of the shell 3, such as Figure 1C shown.

[0030] However, in an embodiment of the present application, a shell assembly is provided, which includes a shell in which a handset, an antenna 1 and an antenna 2 are arranged inside, a display screen arranged on the shell, a sound outlet channel and a sound outlet 2 arranged between the shell and the display screen; wherein, there is a break 1 between the antenna 1 and the antenna 2, and the gap between the display screen and the frame of the shell forms the sound outlet 1, the sound outlet channel is connected with the handset and the sound outlet 1, the sound outlet 2 is connected with the sound outlet channel, and the projection of the sound outlet 2 and the break 1 on the frame of the shell at least partially overlap. On the one hand, since the sound outlet 1 and the sound outlet 2 are arranged in the shell assembly, that is, the shell assembly is provided with a plurality of sound outlets, in the case that one of the sound outlets 1 and the sound outlet 2 is blocked by dust, the other sound outlet may not be blocked by dust, so that when the user is talking, the sound emitted by the handset can still be transmitted to the ear through the sound outlet channel and the other sound outlet, so that when the shell assembly is arranged in an electronic device, the situation where the user cannot use the electronic device to talk can be reduced, thereby improving the convenience of using the electronic device. On the other hand, since the projections of the sound hole 2 and the cutout 1 on the frame of the shell at least partially overlap, when the shell is integrally injection molded, a space will be reserved for the sound hole 2 at the cutout 1 during the injection molding of the shell, which can reduce the volume of the plastic that enters the cutout 1 during the injection molding. Therefore, the thickness of the surface plastic at the position corresponding to the cutout 1 on the frame of the shell after injection molding can be reduced, thereby avoiding shrinkage at this position during injection molding, thereby avoiding shrinkage marks at this position. In this way, the convenience of use of the electronic device can be improved while avoiding shrinkage marks on the shell.

[0031] An embodiment of the present application provides a housing assembly. Figures 2 to 9 FIG. 1 is a schematic diagram showing the structure of the housing assembly provided in an embodiment of the present application. Figures 2 to 9 As shown, the shell assembly provided by the embodiment of the present application includes: a shell 10, in which a sound producing unit 11, a first antenna 12 and a second antenna 13 are arranged, and a first break 14 exists between the first antenna 12 and the second antenna 13; a display screen 15, which is arranged on the shell 10, and a first sound outlet 16 is formed by a gap between the display screen 15 and a frame 101 of the shell 10; a sound outlet channel 17, which is arranged between the shell 10 and the display screen 15, and is connected with the sound producing unit 11 and the first sound outlet 16; a second sound outlet 18, which is arranged on the frame 101 of the shell 10, and is connected with the sound outlet channel 17, and the second sound outlet 18 at least partially overlaps with the projection of the first break 14 on the frame 101 of the shell 10.

[0032] In some embodiments of the present application, the above-mentioned pronunciation unit 11 may include at least one of the following: an earpiece, a speaker. Of course, the pronunciation unit 11 may also include other units, which is not limited in the embodiments of the present application.

[0033] In some embodiments of the present application, Figure 2 and Figure 3 As shown, the shell 10 may include a middle frame 102 and a frame 101. The middle frame 102 may be a metal middle frame, which may include an alloy die-casting, and the surface of the alloy die-casting is wrapped with plastic. It can be understood that the metal middle frame can be integrally injection molded by the alloy die-casting. The metal middle frame is used to install or install various components, such as multiple antennas, display screens 15, etc. Here, the multiple antennas may be installed in the frame 101, and there is a break between two adjacent antennas in the multiple antennas. The multiple antennas may be metal antennas of different frequency bands, and the lengths of the multiple metal antennas may be different, completely the same, or partially the same. The multiple antennas include a first antenna 12 and a second antenna 13.

[0034] For example, in combination Figure 3 A plurality of antennas are installed in the frame 101 , such as a first antenna 12 and a second antenna 13 , and a first break 14 is present between the first antenna 12 and the second antenna 13 .

[0035] Of course, other antennas may be provided in the metal middle frame, which is not limited in the embodiment of the present application.

[0036] In the present application embodiment, combined Figure 3 The first antenna 12 and the second antenna 13 can be installed in the frame 101.

[0037] In some embodiments of the present application, the distance between the first antenna 12 and the first sound outlet 16 is less than or equal to a preset distance; the distance between the second antenna 13 and the first sound outlet 16 is less than or equal to a preset distance.

[0038] In the embodiment of the present application, since the distance between the first antenna 12 and the second antenna 13 and the first sound outlet 16 is less than or equal to the preset distance, the distance between the second sound outlet 18 and the first sound outlet 16 can be made smaller. Therefore, when the first sound outlet 16 is blocked by dust, the user's ear can still clearly hear the sound emitted by the second sound outlet 18 when the ear is close to the first sound outlet 16. In other words, when the first sound outlet 16 is blocked by dust, the user does not need to change the posture during the call, and can directly hear the sound emitted by the second sound outlet 18, so that the user's experience can be improved.

[0039] It can be seen that since the distance between the first antenna and the second antenna and the first sound outlet is less than or equal to the preset distance, the distance between the second sound outlet and the first sound outlet can be made smaller. Therefore, when the first sound outlet is blocked by dust, the user can also directly hear the sound emitted by the second sound outlet, thereby improving the user experience.

[0040] In some embodiments of the present application, Figure 2 As shown, the pronunciation unit 11 can be disposed on the middle frame 102 , and the pronunciation hole of the pronunciation unit 11 can face the display screen 15 .

[0041] In some embodiments of the present application, the gap between the display screen 15 and one frame portion of the frame of the housing 10 forms the first sound outlet 16, and the second sound outlet 18 is provided on another frame portion of the frame of the housing 10. Alternatively, the gap between the display screen 15 and one frame portion of the frame of the housing 10 forms the first sound outlet 16, and the second sound outlet 18 is provided on the one frame portion of the frame of the housing 10.

[0042] In some embodiments of the present application, Figure 4 The gap between the display screen 15 and the first frame portion 103 of the frame 101 of the housing 10 forms the first sound outlet 16 ; the second sound outlet 18 is disposed on the first frame portion 103 .

[0043] In some examples, the first frame portion 103 may be an upper edge of the frame 101 .

[0044] Understandably, combined Figure 3 , the frame 101 of the housing 10 may include a plurality of edges, such as Figure 3 The first sound hole 16 can be formed between the first frame portion (e.g., the upper edge) of the frame 101 and the display screen 15, and the second sound hole 18 is disposed on the upper edge. In this way, the first sound hole 16 and the display screen 15 are in the same plane, and the second sound hole 18 and the first sound hole 16 are in different planes.

[0045] In the embodiment of the present application, dust is easily accumulated on the shell 10, that is, dust is easily accumulated on the first sound outlet hole 16 and the second sound outlet hole 18 when the shell assembly is stationary. The dust accumulated on two different sides of the shell 10 is different. For example, when the shell assembly is stationary, more dust is accumulated on the top surface of the shell 10, while less dust is accumulated on the bottom surface and the side surface. Therefore, the first sound outlet hole 16 and the second sound outlet hole 18 can be set on different surfaces, so as to avoid the situation where a lot of dust accumulates on both the first sound outlet hole 16 and the second sound outlet hole 18, thereby avoiding the situation where the first sound outlet hole 16 and the second sound outlet hole 18 are blocked by dust at the same time.

[0046] It can be seen that since the first sound hole is formed by the gap between the display screen and the first frame part of the frame of the shell, and the second sound hole is arranged on the first frame part, the distance between the first sound hole and the second sound hole can be made smaller. Therefore, when the first sound hole is blocked by dust, the user can also directly hear the sound emitted by the second sound hole, thereby improving the user experience.

[0047] In the embodiment of the present application, the first sound hole 16 is connected to the sound outlet channel 17 , so the sound emitted by the sound hole can be transmitted out of the first sound hole 16 through the sound outlet channel 17 , so that the user can hear the sound emitted by the sound unit 11 through the first sound hole 16 .

[0048] In some embodiments of the present application, the number of the first sound outlet holes 16 is at least two; there are at least two gaps between the display screen 15 and the frame of the housing 10 , and each gap forms a first sound outlet hole 16 .

[0049] It is understandable that since a plurality of first sound holes 16 can be provided, even if a portion of the first sound holes 16 are clogged with dust, another portion of the first sound holes 16 may not be clogged with dust, thereby reducing the probability of all the first sound holes 16 being clogged with dust.

[0050] In the embodiment of the present application, the second sound hole 18 is connected to the sound outlet channel 17 , so the sound emitted by the sound hole can be transmitted to the second sound hole 18 through the sound outlet channel 17 , so that the user can hear the sound emitted by the sound unit 11 through the second sound hole 18 .

[0051] In some embodiments of the present application, the number of the second sound outlet holes 18 is at least two; wherein the at least two second sound outlet holes 18 are evenly distributed on the frame 101 of the housing 10 .

[0052] For example, in combination Figure 3 ,like Figure 5 As shown, it is assumed that the number of the second sound outlet holes 18 may be at least two, and the at least two second sound outlet holes 18 are evenly distributed on the frame 101 .

[0053] As can be seen, since multiple second sound outlet holes can be provided, even if some of the second sound outlet holes are blocked by dust, other second sound outlet holes may not be blocked by dust, thereby reducing the probability of all the second sound outlet holes being blocked by dust.

[0054] In some embodiments of the present application, the second sound hole 18 can be integrally injection molded with the housing 10. It can be understood that since the housing 10 and the second sound hole 18 are integrally injection molded, rather than being opened after the housing 10 is injection molded. That is to say, during injection molding, a setting space will be reserved for the second sound hole 18 at the first break 14, for example, a hole mold is placed in the first break 14, so that the volume of plastic entering the first break 14 during injection molding can be reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first break 14 on the housing can be reduced, thereby avoiding shrinkage at this position during injection molding, thereby avoiding shrinkage marks at this position.

[0055] In some embodiments of the present application, Figure 6 As shown, the shell assembly provided in the embodiment of the present application further includes: a dust storage groove 19, which is disposed in the shell 10 and is at least partially opposite to the second sound outlet 18.

[0056] In the embodiment of the present application, the dust storage groove 19 is at least used to collect dust falling from the second sound outlet 18 .

[0057] In some embodiments of the present application, the dust storage groove 19 may be disposed on a side wall of the sound outlet channel 17 of the housing 10 close to the second sound outlet hole 18 .

[0058] It should be noted that the above “at least partially opposite to the second sound outlet hole 18” can be understood as: the projection of the dust storage groove 19 on the first plane at least partially overlaps with the second sound outlet hole 18; or the projection of the second sound outlet hole 18 on the second plane at least partially overlaps with the dust storage groove 19. The first plane may be the plane where the second sound outlet hole 18 is located, and the second plane may be the plane where the bottom of the dust storage groove 19 is located.

[0059] In the embodiment of the present application, since dust may still fall into the second sound outlet 18, which may cause the second sound outlet 18 to be blocked by dust, a dust storage groove 19 may be provided in the shell assembly so that the dust falling into the second sound outlet 18 can fall into the dust storage groove 19, thereby reducing the probability of dust accumulation in the second sound outlet 18 and reducing the probability of the second sound outlet 18 being blocked.

[0060] It can be seen that since a dust storage groove is also provided in the shell assembly, dust falling into the second sound outlet hole can directly fall into the dust storage groove without accumulating in the second sound outlet hole, thereby reducing the probability of the second sound outlet hole being blocked.

[0061] In some embodiments of the present application, Figure 6 The dust storage groove 19 is at least partially opposite to the first sound outlet hole 16 .

[0062] In the embodiment of the present application, the dust storage groove 19 can also be used to collect dust falling from the first sound outlet 16 .

[0063] It should be noted that the above “at least partially opposite to the first sound outlet 16” can be understood as: the projection of the dust storage groove 19 on the third plane at least partially overlaps with the first sound outlet 16; or the projection of the first sound outlet 16 on the second plane at least partially overlaps with the dust storage groove 19. The third plane may be the plane where the display screen 15 is located.

[0064] In the embodiment of the present application, since a dust storage groove 19 can be provided in the shell assembly, dust falling into the first sound outlet 16 can fall into the dust storage groove 19, thereby reducing the probability of dust accumulation in the first sound outlet 16 and reducing the probability of the first sound outlet 16 being blocked.

[0065] It can be seen that since a dust storage groove is also provided in the shell assembly, dust falling into the first sound outlet can directly fall into the dust storage groove without accumulating in the first sound outlet, thereby reducing the probability of the first sound outlet being blocked.

[0066] In some embodiments of the present application, the dust storage groove 19 is at least partially opposite to the second sound outlet 18, so that the volume of plastic entering the first break 14 during injection molding is further reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first break 14 on the shell can be further reduced, thereby further avoiding shrinkage at this position during injection molding, and thus further avoiding shrinkage marks at this position.

[0067] The embodiment of the present application provides a shell assembly, wherein the shell has a sound unit, a first antenna and a second antenna disposed therein, and a first break exists between the first antenna and the second antenna; a display screen is disposed on the shell, and a first sound outlet is formed by a gap between the display screen and the frame of the shell; a sound outlet channel is disposed between the shell and the display screen, and is connected to the sound unit and the first sound outlet; a second sound outlet is disposed on the frame of the shell, and is connected to the sound outlet channel, and the second sound outlet overlaps at least partially with the projection of the first break on the frame of the shell. On the one hand, since the shell assembly is provided with the first sound outlet and the second sound outlet, that is, the shell assembly is provided with a plurality of sound outlets, in the case that one of the first sound outlet and the second sound outlet is blocked by dust, the other sound outlet may not be blocked by dust, therefore, when the user is talking, the sound emitted by the sound unit can still be transmitted to the ear through the sound outlet channel and the other sound outlet, so that when the shell assembly is disposed in an electronic device, the situation that the user cannot use the electronic device to talk can be reduced, thereby improving the convenience of using the electronic device. On the other hand, since the projections of the second sound outlet and the first cutout on the frame of the shell at least partially overlap, in this way, when the shell is integrally injection-molded, a space will be reserved for the second sound outlet at the first cutout during the injection molding of the shell, so that the volume of plastic that enters the first cutout during the injection molding can be reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first cutout on the frame of the shell after injection molding can be reduced, thereby avoiding shrinkage at this position during injection molding, thereby avoiding shrinkage marks at this position. In this way, the convenience of use of the electronic device can be improved while avoiding shrinkage marks on the shell.

[0068] In some embodiments of the present application, Figure 7 As shown, the shell assembly provided in the embodiment of the present application may also include: a third antenna 20, which is arranged in the shell 10, and the distance between the third antenna 20 and the first sound outlet 16 is greater than the preset distance; a fourth antenna 21, which is arranged in the shell 10, and the distance between the fourth antenna 21 and the first sound outlet 16 is greater than the preset distance.

[0069] In the embodiment of the present application, a second break 22 is provided between the third antenna 20 and the fourth antenna 21 ; a first groove 23 is provided on the side wall of the housing 10 between the second break 22 .

[0070] In the embodiment of the present application, the first groove 23 is at least used to collect dust falling into the sound outlet channel 17 and reduce the thickness of the surface plastic at a position on the housing 10 corresponding to the second break 22 during injection molding.

[0071] In the embodiment of the present application, since the housing 10 is integrally injection molded, and a first groove 23 is provided on the side wall of the housing 10 between the second cutouts 22, the plastic that enters the second cutouts 22 during injection molding can flow into the first groove 23, thereby reducing the volume of the plastic that enters the second cutouts 22 during injection molding. Therefore, the thickness of the surface plastic at the position corresponding to the second cutout 22 on the housing can be reduced, thereby avoiding shrinkage at this position during injection molding, and thus avoiding shrinkage marks at this position.

[0072] It can be seen that since the first groove is provided on the side wall of the shell located between the second fractures, the volume of the plastic entering the second fracture during injection molding can be reduced, thereby avoiding shrinkage at the position corresponding to the second fracture on the shell during injection molding, thereby avoiding shrinkage marks at this position.

[0073] In some embodiments of the present application, Figure 7 As shown, the first groove 23 is at least partially opposite to the first sound outlet 16 .

[0074] It should be noted that the above “at least partially opposite to the first sound outlet 16” can be understood as: the projection of the first groove 23 on the third plane at least partially overlaps with the first sound outlet 16; or the projection of the first groove 23 on the fourth plane at least partially overlaps with the dust storage groove 19. The third plane may be the plane where the display screen 15 is located, and the fourth plane may be the plane where the bottom of the first groove 23 is located.

[0075] In the embodiment of the present application, since the first groove 23 can be set in the shell assembly, the dust falling into the first sound outlet 16 can fall into the first groove 23, which can reduce the probability of dust accumulation in the first sound outlet 16 and reduce the probability of the first sound outlet 16 being blocked.

[0076] It can be seen that, since the first groove is also provided in the shell assembly, dust falling into the first sound outlet hole can directly fall into the first groove without accumulating in the first sound outlet hole, thereby reducing the probability of the first sound outlet hole being blocked.

[0077] In some embodiments of the present application, Figure 7 and Figure 8 As shown, there is a third break 24 between the third antenna 20 and the second antenna 13 ; wherein a second groove 25 is provided on the side wall of the housing 10 between the third break 24 .

[0078] In the embodiment of the present application, since the housing 10 is integrally injection molded, and a second groove 25 is provided on the side wall of the housing 10 between the third cutouts 24, the plastic that enters the third cutouts 24 during injection molding can flow into the second groove 25, thereby reducing the volume of the plastic that enters the third cutouts 24 during injection molding. Therefore, the thickness of the surface plastic at the position corresponding to the third cutout 24 on the housing can be reduced, thereby avoiding shrinkage at this position during injection molding, and thus avoiding shrinkage marks at this position.

[0079] It can be seen that since a second groove is provided on the side wall of the shell between the third fractures, the volume of the plastic entering the third fracture during injection molding can be reduced, thereby avoiding shrinkage at the position corresponding to the third fracture on the shell during injection molding, thereby avoiding shrinkage marks at this position.

[0080] An embodiment of the present application provides an electronic device. Fig. 9 FIG. 1 is a schematic diagram showing the structure of an electronic device provided in an embodiment of the present application. Fig. 9 As shown, the electronic device 30 provided in the embodiment of the present application includes: the housing assembly 31 in the above embodiment.

[0081] The embodiment of the present application provides an electronic device, which includes the housing assembly in the above embodiment. On the one hand, since the housing assembly of the electronic device is provided with a first sound outlet and a second sound outlet, that is, the housing assembly is provided with a plurality of sound outlets, in the case where one of the first sound outlet and the second sound outlet is blocked by dust, the other sound outlet may not be blocked by dust. Therefore, when the user is talking, the sound emitted by the sound unit of the electronic device can still be transmitted to the ear through the sound outlet channel and the other sound outlet, thereby reducing the situation where the user cannot use the electronic device to talk, thereby improving the convenience of using the electronic device. On the other hand, since the projection of the second sound outlet and the first break on the frame of the housing at least partially overlaps, in this way, when the housing is integrally injection molded, a space will be reserved for the second sound outlet at the first break when the housing is injection molded, so that the volume of the plastic entering the first break during injection molding can be reduced. Therefore, the thickness of the surface plastic at the position corresponding to the first break on the frame of the housing can be reduced, thereby avoiding the shrinkage of the position during injection molding, thereby avoiding the shrinkage mark at the position. In this way, the convenience of using the electronic device can be improved while avoiding the occurrence of shrinkage marks on the shell.

[0082] The electronic device in the embodiments of the present application may be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a mobile internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc. It may also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc., and the embodiments of the present application are not specifically limited.
