[0014] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be specifically noted that the following embodiments are only used to illustrate the present application, but do not limit the scope of the present application. Similarly, the following embodiments are only partial embodiments of the present application rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0015] When "embodiment" is mentioned in the present application, it means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present application. Those skilled in the art explicitly and implicitly understand that the embodiments described in the present application may be combined with other embodiments.

[0016] Refer to Figure 1 , Figure 1 which is a schematic disassembly structural diagram of an embodiment of the electronic device provided by the present application.

[0017] In the present application, the electronic device 10 may be a portable device provided with a speaker such as a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. Among them, in this embodiment, the electronic device 10 is taken as an example of a mobile phone for exemplary illustration.

[0018] Combined with Figure 1, the electronic device 10 may include a display module 11 and a housing assembly 12. The display module 11 may be assembled and connected to the housing assembly 12 by one or a combination of assembly methods such as bonding, clamping, welding, etc. Among them, the electronic device 10 may further include a main board 13, a battery 14, and a speaker 15 housed therein, so that the electronic device 10 can implement corresponding functions. For example, structural components such as the display module 11 and the speaker 15 are electrically connected to the main board 13, the battery 14, etc. through flexible printed circuits (FPCs) respectively, so that they can obtain the power supply from the battery 14 and execute corresponding instructions under the control of the main board 13. Among them, the speaker 15 may be located at the bottom of the electronic device 10, for example, at one end of the battery 14 away from the main board 13.

[0019] Furthermore, the electronic device 10 may further include a speaker 16 electrically connected to the main board 13, the battery 14, etc. Among them, different from the speaker 15, the speaker 16 may be located at the top of the electronic device 10, for example, at one end of the main board 13 away from the battery 14. In this way, the speaker 15 and the speaker 16 can cooperate to form a dual speaker, so as to allow the electronic device 10 to achieve stereo sound when playing external sound in application scenarios such as games, music, videos, etc., thereby improving the sound effect of the electronic device 10. Of course, the speaker 15 and the speaker 16 can also be used separately. For example, the speaker 16 is used alone to serve as the earpiece of the electronic device 10; or the speaker 16 can also replace the speaker 15, that is, the electronic device 10 has only one speaker 16.

[0020] It should be noted that: the top and bottom of the electronic device 10 described in this application are defined based on the relative positions when the user holds the electronic device 10 with one hand. For example, when the user holds the electronic device 10 with one hand, the bottom of the electronic device 10 is closer to the user's wrist than its top. Therefore, when the basic structure of the electronic device 10 and its holding and other usage states change, the relative positions and relationships of the speaker 15 and the speaker 16 on the electronic device 10 can also change accordingly.

[0021] However, the inventors of the present application have found in long-term R & D work that: when another speaker 16 is added to the top of the electronic device 10, on the one hand, it will cause the top of the electronic device 10 to be more crowded, and even squeeze the space where the battery 14 is located, making it difficult for the electronic device 10 to carry a large-capacity battery 14; on the other hand, it will also cause the rear sound cavity of the speaker 16 to be not large enough, resulting in poor sound effects of the speaker 16. For example, the sound effects of the speaker 16 are manifested as insufficient low frequency or difficulty in diving. Therefore, an inventive concept of the present application can be: using the gaps between the structural components such as the camera and the flash originally provided on the top of the electronic device 10 or the gaps between them and other surrounding structural components to expand the rear sound cavity of the speaker 16, so that the rear sound cavity of the speaker 16 is as large as possible without occupying the space of other structural components such as the battery 14 as much as possible, thereby improving the sound effects of the speaker 16.

[0022] Refer to jointly Figure 2 and Figure 7 , Figure 2 is a schematic exploded view of an embodiment of the electronic device provided by the present application, Figure 3 is Figure 2 a schematic view of the structure after a part of the structure of the electronic device in Figure 4 is Figure 3 a schematic view of the structure after another part of the structure of the electronic device in Figure 5 is Figure 2 a schematic view of the structure after yet another part of the structure of the electronic device in Figure 6 is Figure 2 a schematic view of the structure after still another part of the structure of the electronic device in Figure 7 is Figure 2 a schematic cross-sectional view of the structure of the electronic device after assembly. It should be noted that: for the convenience of description, Figure 2 only a part of the structure of the electronic device is intercepted, and other structures such as the corresponding battery of the electronic device and the other part of the structure far from the main board are hidden.

[0023] Combined with Figure 2 , the electronic device 10 may further include a functional component 17 and a first housing 121. The functional component 17 may be connected to the main board 13, and the first housing 121 may be connected to the main board 13 to enclose and form the rear sound cavity of the speaker 16, and the functional component 17 may be at least partially located in the rear sound cavity of the speaker 16. In other words, in this embodiment, at least a part of the surrounding space where the functional component 17 is located is absorbed to expand the rear sound cavity of the speaker 16, so that the rear sound cavity of the speaker 16 is as large as possible, thereby improving the sound effects of the speaker 16.

[0024] As an example, combined with Figure 3 and Figure 2, the functional component 17 can be a camera 171 or a flash 172 disposed on one side of the main board 13 facing the first housing 121. For example, the functional component 17 is attached to the main board 13 by surface mount technology (SMT). In this way, both the physical fixation of the functional component 17 and the electrical connection between the functional component 17 and the main board 13 can be achieved. At this time, since the functional component 17 can be entirely located on one side of the main board 13, there is no need to perform a sealing process between the functional component 17 and the main board 13 to meet the airtight requirement of the rear sound cavity of the speaker 16, and the functional component 17 can also be entirely located in the rear sound cavity of the speaker 16. Among them, when the functional component 17 is a camera 171, the camera 171 can be used as a macro camera or a wide-angle camera; different from the main camera: the macro camera or the wide-angle camera does not require a large zoom, for example, it only needs to meet the focusing requirement, so they can be directly attached to the main board 13 by surface mount technology. It should be noted that when the functional component 17 is the main camera, the main camera can pass through the main board 13 via the avoidance hole 131 and perform a sealing process between the two, so as to take into account both the zoom requirement of the main camera and the airtight requirement of the rear sound cavity of the speaker 16. At this time, the functional component 17 can be partially located in the rear sound cavity of the speaker 16.

[0025] It should be noted that: based on the above related description, combined with Figure 3 , for the camera 171, the camera 171 can be classified into a main camera 1711, a wide-angle camera 1712, a macro camera 1713, etc. according to different functions. Their specific structures and related functions are well known to those skilled in the art and will not be elaborated here. Among them, in this embodiment, an example is given to illustrate the expansion of the rear sound cavity of the speaker 16 through the gap between the macro camera 1713 and the flash 172 and the gaps between them and structural components such as the main camera 1711. At this time, the macro camera 1713 and the flash 172 can be at least partially located in the rear sound cavity of the speaker 16, while the main camera 1711 and the wide-angle camera 1712 are located outside the rear sound cavity of the speaker 16. Obviously, in some other embodiments, any one of the macro camera 1713 and the flash 172 can be interchanged with the wide-angle camera 1712, and the expansion requirement of the rear sound cavity of the speaker 16 can also be satisfied.

[0026] As an example, combined with Figure 2 , Figure 3 and Figure 7, the electronic device 10 may further include a second housing 122, a first sealing structure 101, and a fastener 102. The second housing 122 is located on the side of the main board 13 away from the first housing 121. The first sealing structure 101 is disposed between the first housing 121 and the main board 13 to seal the rear sound cavity of the speaker 16, and the fastener 102 can be configured to maintain the compression amount of the first sealing structure 101. Among them, the first sealing structure 101 can be disposed on the side of the main board 13 facing the first housing 121. The first housing 121 can be covered on the main board 13 and partially supported on the first sealing structure 101. Further, the number of the fasteners 102 can be multiple. The multiple fasteners 102 can be spaced apart and distributed around the first sealing structure 101 and connect the first housing 121 and the second housing 122 so that the first housing 121 presses on the first sealing structure 101. At this time, functional components 17 such as a macro camera 1713 and a flash 172 can be located inside the first sealing structure 101.

[0027] Further, the first sealing structure 101 can include a reinforcing matrix and an elastomer connected to the reinforcing matrix. For example, elastomers are connected to both the front and back surfaces of the reinforcing matrix; the reinforcing matrix is used to increase the structural strength of the first sealing structure 101, and the elastomer is used to seal the rear sound cavity of the speaker 16. Among them, the reinforcing matrix can be Polycarbonate (PC), Polyethylene Terephthalate (PET), Polyvinyl Chloride (PVC), etc., and the elastomer can be foam, silica gel, rubber, etc. At this time, colloids can also be provided on both the front and back surfaces of the first sealing structure 101 to allow the first sealing structure 101 to be pre-fixed between the first housing 121 and the main board 13. Correspondingly, the fastener 102 can be a screw, a heat melt post, a buckle, etc. For example: combined Figure 3 and Figure 4 , the fastener 102 is four screws, and they are respectively distributed at the corners of the periphery of the first sealing structure 101; among them, the fastener 102 is replaced by corresponding screw holes.

[0028] As an example, combined Figure 4 and Figure 2 , a first through hole 1211 can be provided on the first housing 121. Based on this, combined with Figure 5 and Figure 2, the electronic device 10 may further include a decorative member 181 and a protective lens 182. The decorative member 181 is used to meet the space requirements during the zooming of the main camera 1711 and the focusing of the wide-angle camera 1712 or the macro camera 1713, and decorates structural members such as the camera 171. The protective lens 182 is used to meet the lighting requirements of the camera 171 and the fill light or illumination requirements of the flash 172. Among them, the decorative member 181 may be connected to the side of the first housing 121 facing away from the main board 13, and may be provided with a second through hole 1811 communicating with the first through hole 1211. The second through hole 1811 serves as the light path of the functional member 17 such as the camera 171 and the flash 172. Further, the protective lens 182 may be connected to the decorative member 181 and cover the second through hole 1811 to allow the rear sound cavity of the speaker 16 to be further expanded to the cavity formed by enclosing the first housing 121, the decorative member 181, and the protective lens 182, so as to make full use of the gaps between these structural members and make the rear sound cavity of the speaker 16 as large as possible.

[0029] Further, when the functional member 17 is the camera 171, the camera 171 may be fixed to the side of the main board 13 facing the first housing 121. For example, the macro camera 1713 is directly mounted on the main board 13 by surface mount technology and passes through the first through hole 1211 to collect light via the second through hole 1811. In this way, not only can the sealing structure of the rear sound cavity of the speaker 16 be simplified, but also the space requirements during the focusing of the macro camera 1713 can be met, and it is also beneficial to further expand the volume of the rear sound cavity of the speaker 16. However, when the functional member 17 is the flash 172, the flash 172 may be fixed to the side of the first housing 121 facing the decorative member 181, and may be electrically connected to the main board 13 through a wiring structure such as a flexible circuit board to emit light outward via the second through hole 1811. In this way, it is not only beneficial to expand the volume of the rear sound cavity of the speaker 16, that is, the area on the side of the first housing 121 facing away from the flash 172 and corresponding to the flash 172 is directly used as a part of the rear sound cavity of the speaker 16, but also the flash 172 can be closer to the outside of the electronic device 10, thereby shortening the distance for the light emitted by the flash 172 to propagate to the outside of the electronic device 10, and then reducing the energy consumption of the flash 172. Among them, the electronic device 10 may further include a light guide member 183, and the light emitted by the flash 172 may be guided by the light guide member 183 to propagate to the outside of the electronic device 10. At this time, the light guide member 183 may partially extend into the second through hole 1811 to be as close as possible to the protective lens 182. Of course, the light guide member 183 and the protective lens 182 may be an integral structural member, such as a glass member or an optical plastic member, and the integral structural member may extend into the decorative member 181 via the second through hole 1811 to be as close as possible to the flash 172.

[0030] Further, in combination withFigure 4 , the first housing 121 may include an integrally connected metal part 1212 and a plastic part 1213. For example, the two are formed by metal insert injection molding process, so that the first housing 121 can be as thin as possible in a local area while taking into account the structural strength, and further making the rear sound cavity of the speaker 16 as large as possible. For example: based on the above related description, when the first sealing structure 101 is attached to the first housing 121, the proportion of the metal part 1212 in the area surrounded by the first housing 121 by the first sealing structure 101 is greater than or equal to 60%. Preferably, the first housing 121 only uses the metal part 1212 as the cavity wall of the rear sound cavity of the speaker 16. Accordingly, combined with Figure 5 , the decorative member 181 may include an integrally connected bottom wall 1812, a cylindrical side wall 1813 and a top wall 1814, and the bottom wall 1812 and the top wall 1814 are respectively located at both ends of the cylindrical side wall 1813. Among them, the decorative member 181 may be a metal part, so that the decorative member 181 can be as thin and light as possible, and can be made into a corresponding structural form by stamping process. At this time, the decorative member 181 can be supported on the metal part 1212 through the bottom wall 1812, and the second through hole 1811 is provided on the top wall 1814; the camera 171 such as the macro camera 1713 can extend into the cylindrical side wall 1813. In other words, an installation groove may be formed on the first housing 121, the metal part 1212 is exposed through the installation groove, the decorative member 181 can be installed in the installation groove, and its bottom wall 1812 may be generally flush with the side of the plastic part 1213 protruding from the metal part 1212.

[0031] Furthermore, combined with Figure 4 and Figure 5 , the electronic device 10 may further include a near-field communication module 19, and the near-field communication module 19 may be disposed on a side of the first housing 121 facing away from the main board 13. Among them, the near-field communication module 19 may be attached to the metal part 1212, that is, similar to the decorative member 181, the near-field communication module 19 may also be located in an installation groove.

[0032] As an example, combined with Figure 2 , Figure 4 and Figure 7, the electronic device 10 may further include a second sealing structure 103 and a limiting structure, the second sealing structure 103 is arranged between the decorative member 181 and the first shell 121 to seal the rear sound cavity of the speaker 16, and the limiting structure may be arranged to maintain the compression amount of the second sealing structure 103. Among them, the second sealing structure 103 may be arranged on the side of the metal part 1212 facing the decorative member 181, the decorative member 181 is covered on the first shell 121, and is partially supported on the second sealing structure 103 by the bottom wall 1812. Further, the limiting structure connects the bottom wall 1812 and the metal part 1212 so that the metal part 181 is pressed on the second sealing structure 103. At this time, the functional parts 17 such as the macro camera 1713 and the flash 172 may be at least partially located on the inner side of the second sealing structure 103.

[0033] Furthermore, the second sealing structure 103 may be foam, silicone, rubber, etc., and may be provided with colloid on both sides thereof to allow the second sealing structure 103 to be pre-fixed between the bottom wall 1812 and the metal part 1212. Accordingly, the limiting structure may be a screw, a hot melt column, a buckle, etc., or may be formed by curing glue such as light-curing glue and heat-curing glue.

[0034] It should be noted that: Figure 2 , Figure 4 and Figure 5 For the camera 171, in addition to the macro camera 1713 being covered by the decorative member 181 and extending into the cylindrical side wall 1813 and collecting light through the second through hole 1811, the main camera 1711 and the wide-angle camera 1712 can also be covered by the decorative member 181 and extend into the corresponding cylindrical side wall 1813 and collect light through the corresponding second through hole 1811. In other words, the number of the second through holes 1811 is four, and the four second through holes 1811 correspond to the main camera 1711, the wide-angle camera 1712, the macro camera 1713 and the flash 172, respectively. Accordingly, in combination with Figure 2 and Figure 6 , each second through hole 1811 can be covered by a protective lens 182 .

[0035] As an example, in combination Figure 6 and Figure 2 The electronic device 10 may further include a first cover plate 123, which is located on the side of the first housing 121 away from the main board 13 and may be provided with a third through hole 1231 and a groove 1232 connected to the third through hole 1231. The decorative element 181 may partially extend into the first cover plate 123 through the third through hole 1231, and the protective lens 182 may be located in the groove 1232, so that the electronic device 10 has a compact structure and is thinner and lighter. Based on this, and in combination with Figure 7The electronic device 10 may further include a third sealing structure 104 and a connector 105. The third sealing structure 104 is disposed between the protective lens 182 and the decorative member 181 to seal the rear acoustic cavity of the speaker 16. The connector 105 may be configured to maintain the compression of the third sealing structure 104. The third sealing structure 104 may be disposed on the side of the top wall 1814 away from the main board 13 and surround the second through hole 1811. The protective lens 182 is pressed against the third sealing structure 104. Furthermore, the protective lens 182 may be connected to the bottom of the groove 1232 through the connector 105 so that the protective lens 182 is pressed against the third sealing structure 104.

[0036] Furthermore, the third sealing structure 104 may be foam, silicone, rubber, etc., and a colloid may be provided on both sides thereof to allow the third sealing structure 104 to be pre-fixed between the top wall 1814 and the protective lens 182. Accordingly, the connector 105 may be a screw, a hot melt column, a buckle, etc., or may be formed by curing a glue such as a light-curing glue and a heat-curing glue, or may be a back glue such as a double-sided tape. Among them, this embodiment is exemplified by taking the connector 105 as a back glue such as a double-sided tape. Based on this, an air hole 1051 may be provided on the connector 105, and the air hole 1051 may be used to accommodate the gas trapped between the protective lens 182 and the first cover plate 123 to avoid defects such as bubbling between the two, thereby ensuring the appearance quality of the electronic device 10. Among them, the number of the air holes 1051 may be multiple, for example Figure 6 and Figure 2 The four through holes shown (i.e., two through holes with larger apertures (referred to as "large holes") and two through holes with smaller apertures (referred to as "small holes")) are preferably evenly distributed in the area of the connector 105 used to connect the protective lens 182 and the first cover plate 123. It is worth noting that the hole spacing between the two large holes can be greater than the hole spacing between the two small holes, and the two large holes can be used as positioning holes when the connector 105 is assembled.

[0037] It should be noted that: Figure 2 , Figure 6 and Figure 7 , unlike the camera 171 (e.g., the macro camera 1713), the light guide 183 is generally stationary relative to the decorative member 181, so that the second through hole 1811 opposite to the flash 172 can be sealed by the colloid between the light guide 183 and the decorative member 181, without the need to provide an additional third sealing structure 104, thereby simplifying assembly and reducing costs. In other words, the third sealing structure 104 is provided at the periphery of the second through hole 1811 opposite to the macro camera 1713, while the third sealing structure 104 is not provided at the periphery of the second through hole 1811 opposite to the flash 172.

[0038] Refer to Figure 8 , Figure 8 which Figure 2 is a schematic diagram of the disassembly structure of the electronic device from another perspective. It should be noted that: if Figure 2 mainly shows the relevant structural components from the back of the electronic device, then Figure 8 mainly shows the relevant structural components from the front of the electronic device.

[0039] Combined with Figure 2 and Figure 8 , the speaker 16 can be connected to the second housing 122 to enclose and form the front sound cavity of the speaker 16, and the second housing 122 can be provided with a sound outlet hole 1221 communicating with the front sound cavity of the speaker 16. Among them, the specific structure of the speaker 16 is well known to those skilled in the art and will not be described in detail here; correspondingly, the front sound cavity of the speaker 16 is generally located on the side of its diaphragm facing away from the magnet, while the rear sound cavity of the speaker 16 is generally located on the side of its diaphragm facing the magnet. Further, combined with Figure 3 , the speaker 16 can partially extend into the rear sound cavity of the speaker 16 through the avoidance hole 132 on the main board 13, so that the structure of the electronic device 10 is compact and thinner.

[0040] As an example, combined with Figure 8, the second housing 122 may include a middle plate 1222 and a frame 1223 connected to the middle plate 1222. For example, the frame 1223 is disposed around the middle plate 1222 and extends at least toward one side of the middle plate 1222. Wherein, the outlet end of the sound outlet hole 1221 away from the speaker 16 may be located on the frame 1223. Further, the electronic device 10 may further include a display screen 111 and a second cover plate 112 connected to the display screen 111. Wherein, the display screen 111 may be supported on the side of the middle plate 1222 facing away from the main board 13. For example, the display screen 111 and the middle plate 1222 are connected by an adhesive such as double-sided tape; the second cover plate 112 may be supported on the side of the display screen 111 facing away from the middle plate 1222 and further supported on the frame 1223. For example, the middle area of the second cover plate 112 is connected to the display screen 111 by an adhesive such as Optically Clear Adhesive (OCA) and Pressure Sensitive Adhesive (PSA), and the edge area is connected to the frame 1223 by a dispensing process. Further, the second cover plate 112 may be provided with an avoidance through hole or an avoidance notch 1121 for avoiding the outlet end of the sound outlet hole 1221, so as to allow the sound generated by the speaker 16 to better spread to the outside of the electronic device 10. Wherein, when the second cover plate 112 is provided with an avoidance notch, a dust-proof net may further cover the outlet end of the sound outlet hole 1221; and when the second cover plate 112 is provided with an avoidance through hole, the number of the avoidance through holes may be multiple, so as to allow the second cover plate 112 to replace the dust-proof net covering the outlet end of the sound outlet hole 1221.

[0041] The foregoing are only some embodiments of the present application, and thus do not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
