Description

Housing assembly and electronic device

[0001] The present application claims priority from the Chinese patent application No. 202411397174.6 filed on September 30, 2024, and entitled "Housing assembly and electronic device", the content of which is incorporated herein in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of electronic devices, and in particular to a housing assembly and an electronic device. BACKGROUND

[0003] A microphone is an electronic device that converts a sound signal into an electric signal, and is widely used in electronic devices such as mobile phones and tablet computers. In recent years, audio and video media functions such as video recording, live streaming, video calls and WeChat calls have become mainstream applications of electronic devices. When a user is shooting a video, it is desirable to collect the sound in the direction of the video shooting and to reduce the ambient sound; when a user is making a video call or WeChat call, it is desirable to clearly hear the sound of the other user; and when a user is live streaming, it is desirable to collect the sound in the direction of the video shooting and the sound of the main shooting character. Therefore, a microphone is usually arranged near the camera module of an electronic device to achieve functions such as call noise reduction and sound focusing.

[0004] In related technologies, in order to guide external sound into a microphone to achieve sound-electric signal conversion, a sound pickup opening is usually formed on a housing assembly of an electronic device, a sound pickup channel is arranged between the sound pickup opening and the microphone, and a sound signal (for example, a sound wave) outside the electronic device enters the sound pickup channel from the sound pickup opening and is conducted to the microphone through the sound pickup channel, and the microphone picks up the sound signal.

[0005] The pickup opening is arranged on the back of the shell assembly, and its arrangement position has a great influence on the appearance effect of the electronic device. The existing pickup opening is usually arranged on the back of the camera decoration piece, and the pickup channel is also arranged on the camera decoration piece. The microphone is arranged in a stack between the camera decoration piece and the mainboard, which occupies the stacking space in the thickness direction of the electronic device, and is not conducive to the lightweight design of the whole machine. One solution is to arrange a hole on the lens of the camera decoration piece. At this time, the position of the pickup opening is affected by the appearance design, and the position of the microphone is also limited. Or the pickup opening is arranged on the side surface of the camera decoration piece, which can achieve good hiding effect and increase the flexibility of the position. However, due to the design requirements of the stacking space, the internal functional devices need to be avoided multiple times, which leads to a long path of the pickup channel and affects the sound collection effect. Further, the functions of the electronic device are becoming more and more powerful, and there are more and more functional devices on the mainboard. In addition, with the development of shooting technology, the volume of the camera module of the electronic device is also getting larger and larger, and the mainboard and the camera module are constantly occupying the installation space of the microphone, and the installation position of the microphone is more and more limited. In the era of lightweight electronic devices, the scheme of stacking the microphone between the camera decoration piece and the mainboard is no longer applicable. Some existing technologies improve the position of the pickup opening and the path of the pickup channel, and strive to provide enough installation space for the microphone. However, most of them need to increase the length of the pickup channel, which leads to a long pickup path of the microphone and a great discount of the sound collection effect.

[0006] Therefore, the prior art cannot balance the installation space and the sound collection effect of the microphone. SUMMARY

[0007] The shell assembly and the electronic device provided by the embodiments of the present application solve the problem that the prior art cannot balance the installation space and the sound collection effect of the microphone.

[0008] The first aspect of the embodiments of the present application provides a shell assembly, comprising:

[0009] The shell is provided with a mounting hole.

[0010] The camera decoration piece penetrates the mounting hole on the shell, and at least part of the camera decoration piece protrudes relative to the back of the shell.

[0011] The pickup channel has one end, which is a pickup opening located on the back of the shell assembly, and the other end of the pickup channel is used to communicate with a microphone, so that the sound waves from the back of the shell assembly enter the pickup channel through the pickup opening and are transmitted to the microphone through the pickup channel.

[0012] And the sound pickup channel comprises a sound pickup through hole arranged at the part of the shell around the mounting hole and extending from the back surface of the shell to the front surface.

[0013] The shell assembly provided by the embodiment of the present application has the camera decoration piece fixedly connected to the mounting hole of the shell. The sound pickup channel is arranged on the shell assembly, and the sound outside the shell assembly can enter through the sound pickup port of the sound pickup channel and be transmitted along the sound pickup channel to the microphone to realize sound collection. The sound pickup channel comprises a sound pickup through hole arranged at the part of the shell around the mounting hole. In other words, a part of the sound pickup channel is arranged on the shell and located around the mounting hole. In this way, the microphone can be installed below the sound pickup through hole (on the side opposite to the sound pickup port), that is, around the mounting hole. The camera module is located in the mounting hole, and the microphone is installed around the mounting hole, which can be dislocated from the camera module. The microphone does not need to be stacked between the camera module and the mainboard, thereby obtaining a larger installation space. Moreover, the functional device does not need to be designed to avoid the camera decoration piece, the path design of the entire sound pickup channel can be more simple, the length of the sound pickup path can be shortened, and the stability of sound pickup and the sound collection quality of the microphone are improved.

[0014] Therefore, the shell assembly provided by the embodiment of the present application can balance the installation space and sound collection effect of the microphone.

[0015] In a possible implementation manner, the camera decoration piece comprises an outer decoration piece, and the outer decoration piece has an outer skirt surrounding the outer periphery of the mounting hole and arranged on the back surface of the part of the shell around the mounting hole.

[0016] The shell assembly further comprises a first waterproof sealing piece surrounding the outer periphery of the mounting hole. The first waterproof sealing piece is arranged between the back surface of the part of the shell around the mounting hole and the outer surface of the outer skirt facing the surface of the shell, so that the back surface of the shell and the outer decoration piece are sealingly connected.

[0017] The sound pickup through hole is located on the outer periphery side of the first waterproof sealing piece.

[0018] In the above manner, the first waterproof sealing piece is sealingly connected between the camera decoration piece and the shell. Correspondingly, the first waterproof sealing piece can be arranged between the outer skirt of the outer decoration piece and the region around the mounting hole of the shell, so as to ensure the waterproof sealing effect of the shell assembly. The sound pickup through hole is located on the outer side of the first waterproof sealing piece. On the premise that the waterproof sealing effect between the camera decoration piece and the shell is good, the sound pickup channel can still directly penetrate the shell, and the waterproof sealing piece does not need to be designed to avoid the sound pickup channel, thereby obtaining the shortest path of the sound pickup channel.

[0019] In a possible implementation, the first waterproof seal is arranged as a sealing adhesive layer.

[0020] With the above scheme, the camera decoration part is pasted on the shell of the electronic device through the first waterproof seal while meeting the waterproof sealing requirement of the shell assembly, thereby playing a fixing role and reducing the risk of the camera decoration part falling off the shell.

[0021] In a possible implementation, the shell has an extension table protruding towards the center of the mounting hole relative to other regions in the part around the mounting hole.

[0022] The sealing region of the first waterproof seal corresponding to the extension table is arranged as an inner recess structure recessed towards the center of the mounting hole relative to other sealing regions, and the inner recess structure is formed with an avoidance space covering the sound pickup through hole, and the sound pickup channel further includes at least part of the avoidance space.

[0023] With the above scheme, the surrounding region of the mounting hole on the shell is provided with an extension table protruding towards the center of the mounting hole, and the sound pickup through hole penetrates through the extension table. The extension table can be arranged at any position around the mounting hole, for arranging the connection microphone, so that the microphone is placed at a position inside the shell assembly more freely, and the flexibility of the microphone position design is increased. Correspondingly, the first waterproof seal forms an inner recess structure along the outer periphery of the extension table, that is, the waterproof sealing integrity between the camera decoration part and the shell is also ensured at the arrangement position of the microphone, the risk of external liquid entering the internal space of the shell assembly from the gap between the camera decoration part and the shell is reduced, and a waterproof and breathable structure is usually arranged in the channel between the sound pickup port and the microphone, so that the sound outside the shell assembly can normally enter through the sound pickup port of the sound pickup channel, be transmitted along the sound pickup channel to the microphone to realize sound collection, while the external liquid can be prevented from entering the internal space of the shell assembly from the sound pickup through hole.

[0024] In a possible implementation, the sound pickup channel further includes a decoration part channel formed on the outer decoration part, one end of the decoration part channel constitutes the sound pickup port, and the other end is located on the surface of the outer decoration part facing the back of the shell and communicates with the sound pickup through hole. Moreover, the orthographic projection of the decoration part channel to the back of the shell is located on the outer periphery side of the first waterproof seal.

[0025] When the shell assembly has the avoidance space and the shell has the extension table, the other end of the decoration part channel communicates with the sound pickup through hole through the avoidance space, and part or all of the orthographic projection of the decoration part channel to the back of the shell is located on the extension table of the shell.

[0026] With the above scheme, the pickup channel includes a decorative piece channel on the outer decorative piece, the decorative piece channel is located outside the first waterproof sealing piece in the orthographic projection on the back of the shell, and the decorative piece channel is directly communicated with the pickup through hole, so that the path of the pickup channel in the outer decorative piece is shortened, the pickup stability is improved, meanwhile, the first waterproof sealing piece is prevented from being broken by the pickup channel, and the integrity of the waterproof sealing of the shell assembly is ensured.

[0027] In a possible implementation, the pickup port is arranged in a direction perpendicular to the thickness direction of the shell assembly, and in the thickness direction of the shell assembly, the pickup port is shielded by the end of the outer decorative piece away from the shell.

[0028] With the above scheme, the pickup port is located on the peripheral side surface of the outer decorative piece and is shielded by the outer decorative piece in the thickness direction of the shell assembly, so that the visible range of the pickup port on the back of the shell assembly is reduced, a certain angle hiding effect is achieved, and the appearance aesthetics is improved.

[0029] In a possible implementation, the channel part of the decorative piece channel containing the pickup port is arranged obliquely towards the side of the camera decorative piece close to the shell.

[0030] With the above scheme, the decorative piece channel communicated with the pickup port is arranged obliquely at least partially towards the side of the camera decorative piece close to the shell, and is designed as an oblique angle at the bend from a right angle, which is beneficial to shorten the length of the pickup channel, improve the pickup effect of the microphone, and on the other hand, ensure the structural strength of the outer decorative piece at the opening, and improve the reliability of the product structure.

[0031] In a possible implementation, the shell assembly further includes a first sealing piece, the first sealing piece is arranged around the outer peripheral side of the other end of the decorative piece channel and the outer peripheral side of the pickup through hole, and is sealingly connected between the back of the shell and the outer decorative piece.

[0032] When the shell assembly has a relief space and the shell has an extension table, the first sealing piece is sealingly connected between the extension table of the shell and the outer decorative piece, and is located in the relief space.

[0033] With the above scheme, the first sealing piece ensures the sealing connection between the pickup through hole on the shell and the camera decorative piece, prevents the sound wave from leaking at the connection between the camera decorative piece and the shell, ensures the effective transmission of the sound wave along a specific path, and achieves good pickup effect of the microphone.

[0034] In a possible implementation, the outer decoration piece includes a first decoration piece and a second decoration piece which are arranged in a thickness direction of the shell assembly and are sealingly connected, the outer skirt is formed on the second decoration piece, the first decoration piece is located away from the side of the second decoration piece facing away from the shell, and in a plane perpendicular to the thickness direction of the shell assembly, the second decoration piece protrudes from an outer peripheral surface of the first decoration piece.

[0035] Further, the sound pickup port is arranged on the outer peripheral surface of the first decoration piece and is located close to the outer surface of the second decoration piece, and the sound pickup port faces the side away from the center of the camera decoration piece.

[0036] In a possible implementation, the camera decoration piece further includes an inner decoration piece, the inner decoration piece includes an inner decoration body and an inner skirt connected to the inner decoration body, the inner skirt is fixedly and sealingly connected to the front surface of the shell, and the inner decoration body is fixedly connected to the outer decoration piece.

[0037] The inner decoration piece is provided with a notch at a position corresponding to the sound pickup hole, the notch covers the sound pickup hole, and the notch is used to arrange the microphone.

[0038] With the above scheme, one side surface of the shell in the shell assembly is fixedly and sealingly connected to the outer decoration piece, the other side surface of the shell is fixedly connected to the inner decoration piece, and the inner decoration piece and the outer decoration piece are fixedly connected, thereby avoiding or reducing the risk of the camera decoration piece falling off the shell, improving the stability of the camera decoration piece fixed to the shell, and improving the quality of the electronic device.

[0039] A second aspect of the embodiment of the present application provides an electronic device including the shell assembly provided in any of the above implementation manners, and further including a microphone assembly including a microphone, the microphone assembly being sealingly connected to the front surface of the shell and being located at a region where the sound pickup hole is located in the part around the mounting hole.

[0040] The electronic device provided in the embodiment of the present application has sufficient installation space for the microphone assembly, facilitating arrangement of the microphone. The microphone assembly and the shell are sealingly connected, thereby avoiding leakage of sound waves at the position and affecting the sound receiving effect of the microphone.

[0041] In a possible implementation, the microphone assembly further includes a flexible circuit board module, the flexible circuit board module is fixedly and electrically connected to the microphone and is located between the circuit board of the microphone and the front surface of the shell, and a side of the flexible circuit board module away from the microphone is sealingly connected to the front surface of the shell.

[0042] Further, the flexible circuit board module is provided with a sound receiving hole, one end of the sound receiving hole is connected to the sound pickup hole, and the other end of the sound receiving hole is connected to the microphone.

[0043] The electronic device further comprises a support arranged in the cavity of the shell assembly, and the microphone is fixed to the support through the flexible circuit board module.

[0044] According to the above scheme, the microphone is fixed and electrically connected with the flexible circuit board module, so that the transmission of the electric signal is realized.

It should be noted that the specific structure and specific arrangement position of the main microphone assembly and the secondary microphone assembly are not limited in the present application, and a person skilled in the art can design the main microphone assembly and the secondary microphone assembly according to actual needs.

[0085] Please refer to FIGS. 6-7b, FIG. 6 is a partial side view structural schematic diagram of the electronic device of the embodiment of the present application; FIG. 7a is a cross-sectional view structural schematic diagram of the A-A direction in FIG. 6, and FIG. 7b is a partial cross-sectional view structural schematic diagram of the shell assembly in the embodiment of the present application.

[0086] As shown in FIG. 5, the microphone assembly of the electronic device 100 includes a third microphone assembly, i.e., the microphone assembly 400, which includes a microphone 410. The microphone assembly 400 is sealingly connected to the front surface of the shell 310 and located at the area where the sound pickup through hole 341 is located in the part around the mounting hole 311. The microphone assembly 400 is arranged around the camera module 71 and has functions such as auxiliary noise reduction and sound focusing. The electronic device 100 provided in the embodiment of the present application has sufficient installation space for the microphone assembly 400 to facilitate the arrangement of the microphone 410. The microphone assembly 400 and the shell 310 are sealingly connected to avoid sound leakage at this place and affect the sound collection effect of the microphone.

[0087] Further, as shown in FIGS. 3, 6 and 7a, the internal chamber of the shell assembly 300 is also provided with a sound pickup channel 340. One end of the sound pickup channel 340 is the sound pickup port 330 located on the back surface of the shell 310, and the other end of the sound pickup channel 340 is used to communicate with the microphone assembly 400, so that the sound waves from the back surface of the shell assembly 300 enter the sound pickup channel 340 through the sound pickup port 330 and are transmitted to the microphone assembly 400 through the sound pickup channel 340. Or it can be understood that the sound pickup port 330 is the entrance of the sound pickup channel 340, and external sound can enter the sound pickup channel 340 from the sound pickup port 330 and then be transmitted to the microphone 410 in the microphone assembly 400 to realize sound collection.

[0088] As shown in FIGS. 5-7b, the sound pickup passage 340 includes a sound pickup through hole 341, which is arranged at a portion of the shell 310 around the mounting hole 311 and extends from the back surface to the front surface of the shell 310.

[0089] The shell assembly 300 provided in the embodiments of the present application is fixedly connected with the camera decoration piece 320 at the mounting hole 311 of the shell 310. The sound pickup passage 340 is arranged on the shell assembly 300, and the sound outside the shell assembly 300 can enter through the sound pickup port 330 of the sound pickup passage 340 and be transmitted along the sound pickup passage 340 to the microphone assembly 400 to realize sound collection. The sound pickup passage 340 includes the sound pickup through hole 341, which is arranged at a portion of the shell 310 around the mounting hole 311. It can be understood that a portion of the sound pickup passage 340 is arranged on the shell 310 and located around the mounting hole 311. In this way, the microphone 410 can be installed below the sound pickup through hole 341 (on the side opposite to the sound pickup port 330), that is, around the mounting hole 311. The camera module 71 is located in the mounting hole 311, and the microphone 410 is installed around the mounting hole 311, which can be staggered with the camera module 71, without being stacked between the camera module 71 and the mainboard 600, so that a larger installation space is obtained. Moreover, the functional device does not need to be designed to avoid in the camera decoration piece 320, so that the path design of the entire sound pickup passage 340 is more simple, the length of the sound pickup path can be shortened, and the stability of sound pickup is improved, and the sound collection quality of the microphone 410 is higher.

[0090] Therefore, the shell assembly 300 and the electronic device 100 provided in the embodiments of the present application can balance the installation space and the sound collection effect of the microphone 410.

[0091] It can be understood by those skilled in the art that the shapes of the sound pickup port 330 and the sound pickup passage 340 are not limited, the sound pickup port 330 can be circular, elliptical, directional, irregular, etc., and any cross section of the sound pickup passage 340 can be circular, elliptical, directional, irregular, etc., and the drawings are only schematic. The inner wall surface of the sound pickup passage 340 can be a smooth surface or a rough surface, which is not limited in the present application. The specific extension path of the sound pickup passage 340 is not limited, and the specific position of the sound pickup port 330 on the back surface of the shell assembly 300 is not limited, for example, it can be located on the shell 310 or the camera decoration piece 320, and several possible scenarios will be described below in conjunction with the drawings.

[0092] Please refer to FIG. 8a-8c, FIG. 8a is a schematic diagram of a cross-sectional structure of a sound pickup channel in the shell assembly of the embodiment of the present application, FIG. 8b is a schematic diagram of a structure of a sound pickup channel in the shell assembly of the embodiment of the present application, and FIG. 8c is a schematic diagram of a structure of a sound pickup channel in the shell assembly of the embodiment of the present application.

[0093] As shown in FIG. 8a, in one possible implementation, the sound pickup port 330 is located on the back of the shell 310. For example, the sound pickup port 330 can be arranged near the surrounding area of the camera decoration 320, so as to facilitate the microphone 410 to better pick up and record the sound outside the electronic device 100. One end of the sound pickup through hole 341 is connected to the sound pickup port 330, and the other end is connected to the microphone 410 of the microphone assembly 400. That is, when the sound pickup port 330 is located on the back of the shell 310, the sound pickup channel 340 only includes the sound pickup through hole 341, and the length of the sound pickup channel 340 can be the shortest, and the sound pickup effect is better. The sound pickup port 330 can be arranged near the camera decoration 320, that is, the opening of the sound pickup port 330 is further close to the inside of the shell 310 on the basis of being exposed on the back of the shell 310, so as to improve the hiding effect of the sound pickup port 330, and further improve the appearance of the electronic device 100.

[0094] As can be understood by those skilled in the art, in order to ensure the appearance of the electronic device, the sound pickup port 330 can be arranged on the camera decoration 320, such as the schemes shown in FIG. 7a, FIG. 8b and FIG. 8c. The specific position of the sound pickup port 330 on the camera decoration 320 is not limited. For the convenience of understanding the scheme, the structure of the camera decoration 320 will be explained first.

[0095] As shown in FIG. 5, FIG. 7a, FIG. 7b, in one possible implementation, the camera decoration 320 includes an outer decoration 322, which has an outer skirt surrounding the outer periphery of the mounting hole 311 and arranged on the back of the portion of the shell 310 around the mounting hole 311. In one possible implementation, the camera decoration 320 further includes an inner decoration 323, which includes an inner decoration body 3231 and an inner skirt 3232 (see FIG. 11) connected to the inner decoration body 3231, the inner skirt 3232 is fixedly and sealingly connected to the front of the shell 310, and the inner decoration body 3231 is fixedly connected to the outer decoration 322. As shown in FIG. 7a, the inner decoration 323 is provided with a notch at a position corresponding to the sound pickup through hole 341, the notch covers the sound pickup through hole 341 and is used to arrange the microphone 410. The side surface of the shell 310 in the shell assembly 300 is fixedly and sealingly connected to the outer decoration 322, the other side surface of the shell 310 is fixedly connected to the inner decoration 323, and the inner decoration 323 and the outer decoration 322 are fixedly connected, which avoids or reduces the risk of the camera decoration 320 falling off from the shell 310, improves the stability of the camera decoration 320 fixed to the shell 310, and thus improves the quality of the electronic device 100.

[0096] It should be noted that the structures of the outer decoration 322 and the inner decoration 323 are not limited. In one possible implementation, the outer decoration 322 includes a first decoration 3221 and a second decoration 3222 which are stacked and sealingly connected in the thickness direction Z of the shell assembly 300, the outer skirt is formed on the second decoration 3222, the first decoration 3221 is located on the side of the second decoration 3222 away from the shell 310, and in the plane perpendicular to the thickness direction Z of the shell assembly 300, the second decoration 3222 protrudes from the outer peripheral surface of the first decoration 3221.

[0097] The connection mode of the first decoration 3221 and the second decoration 3222 is not limited, and the two can be bonded by point gluing or back gluing, or can be fixedly and sealingly connected by welding or other processing methods. Alternatively, the first decoration 3221 and the second decoration 3222 can also be designed as an integrated structure, which is not limited in the present application. In one possible implementation, the inner decoration 323 and the outer decoration 322 are fixedly connected by screws (see FIG. 11) and part of the point glue (not shown in the figure). Generally, six screw connections can be provided on the inner decoration body 3231, and the point glue is filled in intervals for reinforcement, which further reliably fixes the outer decoration 322 to the shell 310 and avoids the risk of the outer decoration 322 falling off from the shell 310. It can be understood that the present application does not limit the fixed connection mode between the inner decoration 323 and the outer decoration 322.

[0098] The inner decoration piece 323 is provided with an adhesive piece 390 (see FIG. 11) fixedly connected to the front surface of the shell 310 and the inner skirt 3232, and the back surface of the shell 310 is provided with a first waterproof sealing piece 350 for fixedly connecting the outer decoration piece 322. It can be understood that the outer decoration piece 322, the shell 310, and the inner decoration piece 323 are fixedly connected in a sandwich layer through the first waterproof sealing piece 350 and the adhesive piece 390, that is, at least part of the shell 310 is clamped between the inner skirt 3232 of the inner decoration piece 323 and the outer skirt of the outer decoration piece 322, which reduces the risk of the camera decoration piece 320 falling off the shell 310, improves the stability of the camera decoration piece 320 fixed to the shell 310, and thus improves the quality of the electronic device 100.

[0099] The inner decoration piece 323 can be a metal decoration piece, and the outer decoration piece 322 can also be a metal decoration piece. The material of the metal decoration piece includes but is not limited to iron, steel, stainless steel, or aluminum. Alternatively, the inner decoration piece 323 can be a plastic decoration piece, and the outer decoration piece 322 can also be a plastic decoration piece. Through the combined assembly of the inner decoration piece 323 and the outer decoration piece 322, the assembly strength and stability of the electronic device 100 can be improved, and the appearance of the electronic device 100 can be improved. It can be understood by those skilled in the art that, in order to meet the appearance requirement of the appearance, the appearance quality of the metal is considered, the outer decoration piece 322 or the inner decoration piece 323 can adopt a nano injection molding process to directly injection mold plastic on the metal surface, realize one-piece molding of metal and plastic, reduce processing steps, reduce production cost, and reduce the weight of the camera decoration piece 320, prolong the service life, and improve the quality of the whole electronic device. The processing technology of the camera decoration piece 320 is not limited in the present application.

[0100] As shown in FIGS. 7a and 7b, in one possible implementation, the sound pickup port 330 is arranged on the outer circumferential surface of the first decoration piece 3221 and located close to the outer surface of the second decoration piece 3222. The sound pickup port 330 faces away from the center of the camera decoration piece 320. Specifically, in one possible implementation, the sound pickup port 330 is arranged in a direction perpendicular to the thickness direction Z of the shell assembly 300, and in the thickness direction Z of the shell assembly 300, the sound pickup port 330 is shielded by the end of the outer decoration piece 322 away from the shell 310. The sound pickup port 330 is located on the circumferential surface of the outer decoration piece 322 and is shielded by the outer decoration piece 322 in the thickness direction Z of the shell assembly 300. In this way, the visible range of the sound pickup port 330 on the back surface of the shell assembly 300 is reduced, a certain angle of hiding effect is achieved, and the appearance is improved.

[0101] As shown in FIG. 7a, in one possible implementation, the pickup channel 340 further includes a decorative piece channel 342 formed on the outer decorative piece 322, one end of the decorative piece channel 342 constituting the pickup port 330, and the other end located on the surface of the outer decorative piece 322 facing the back of the shell 310 and in communication with the pickup through hole 341. After external sound enters from the pickup port 330, it enters the microphone assembly 400 along the decorative piece channel 342 and the pickup through hole 341 in sequence.

[0102] As shown in FIG. 7a, in one possible implementation, the channel portion of the decorative piece channel 342 containing the pickup port 330 is arranged obliquely toward the side of the center of the camera decorative piece 320 close to the shell 310. Or it can be understood that the decorative piece channel 342 in communication with the pickup port 330 is arranged obliquely at least partially toward the side of the center of the camera decorative piece 320 close to the shell 310, and is designed as an oblique angle at the turning point from a right angle, which is conducive to shortening the length of the pickup channel 340, improving the sound pickup effect of the microphone 410, and on the other hand, ensuring the structural strength of the outer decorative piece 322 at the opening, thereby improving the reliability of the product structure. The decorative piece channel 342 can be arranged obliquely as a whole or only partially, and the present application does not limit this. The extension direction of the decorative piece channel 342 can be a straight line, a curved line or a broken line, and the present application does not limit this.

[0103] The pickup port 330 can also be arranged at other positions of the camera decorative piece 320. As shown in FIG. 8b, in one possible implementation, the pickup port 330 is located on the back of the first decorative piece 3221, and the opening of the pickup port 330 faces the thickness direction Z parallel to the shell assembly 300. As shown in FIG. 8c, in one possible implementation, the pickup port 330 can also be located on the back of the second decorative piece 3222, and the opening of the pickup port 330 faces the thickness direction Z parallel to the shell assembly 300.

[0104] Those skilled in the art can understand that the shell assembly 300 needs to cooperate with the position of the pickup channel 340 to make some waterproof structure to ensure the sealing of the electronic device. The following examples illustrate several possible solutions in combination with the drawings.

[0105] Please refer to FIGS. 9-11, FIG. 9 is a partial structural schematic diagram of a shell of a shell assembly in an embodiment of the present application; FIG. 10 is a partial exploded structural schematic diagram of a shell assembly and a camera decorative piece in an electronic device in an embodiment of the present application; and FIG. 11 is a cross-sectional structural schematic diagram of a camera decorative piece in an electronic device in an embodiment of the present application.

[0106] As shown in FIG. 5, FIG. 7a, FIG. 9 to FIG. 11, in one possible implementation, the shell assembly 300 further includes a first waterproof seal 350 surrounding the outer periphery of the mounting hole 311. The first waterproof seal 350 is arranged between the back surface of the shell 310 at the portion around the mounting hole 311 and the surface of the outer skirt of the outer decorative piece 322 (i.e., the first waterproof seal 350 is arranged between the back surface of the outer decorative piece 322 and the shell 310), so that the shell 310 is sealingly connected between the back surface and the outer decorative piece 322. The sound pickup through hole 341 is located on the outer periphery side of the first waterproof seal 350. The camera decorative piece 320 and the shell 310 are sealingly connected by the first waterproof seal 350. Correspondingly, the first waterproof seal 350 can be arranged between the area around the mounting hole 311 on the shell 310 and the outer skirt of the outer decorative piece 322, to ensure the waterproof sealing effect of the shell assembly 300. While the sound pickup through hole 341 is located on the outer side of the first waterproof seal 350, the sound pickup channel 340 can still directly penetrate the shell 310 without avoiding the design of the waterproof seal, thereby obtaining the shortest path of the sound pickup channel 340, on the premise of ensuring the waterproof sealing effect between the camera decorative piece 320 and the shell 310.

[0107] The specific form of the first waterproof seal 350 is not limited, for example, it can be sealing glue, rubber ring, etc. In one possible implementation, the first waterproof seal 350 is arranged as a sealing glue layer. While meeting the waterproof sealing requirement of the shell assembly 300, the camera decorative piece 320 is glued to the shell 310 of the electronic device by the first waterproof seal 350, thereby playing a fixing role and reducing the risk of the camera decorative piece 320 falling off the shell 310. For example, the sealing glue layer can be formed by a dispensing process. The dispensing process is a process in the industrial production of electronic products, which applies white glue, red glue, UV glue, etc. to the components between each other, thereby playing a role of reinforcing, sealing and insulating between each component, and playing a role of moisture and humidity prevention and heat conduction for functional devices in the shell assembly 300, thereby playing a protective role for the above-mentioned devices to the greatest extent, so that the quality of the electronic device 100 is more stable. In addition, when reinforced by dispensing, it also has the effect of shielding electromagnetic interference, avoiding the problem of electronic device 100 failure caused by deformation under external force. The sealing glue layer can also be adhesive, which can bond the components together, thereby avoiding problems such as falling off and moving of each component. The adhesive can be attached to the back of the electronic device 100, which can effectively prevent the back of the shell assembly 300 from being worn and damaged, thereby prolonging the use time of the electronic device 100.

[0108] As shown in FIG. 7a, FIG. 9 to FIG. 11, in one possible implementation, the housing 310 is located in the portion around the mounting hole 311, and the area with the sound pickup through hole 341 is arranged as an extension platform 312 protruding towards the center of the mounting hole 311 relative to other areas. The sealing area of the first waterproof sealing member 350 corresponding to the extension platform 312 is arranged as a concave structure recessed towards the center of the mounting hole 311 relative to other sealing areas, and the concave structure is formed with a clearance space covering the sound pickup through hole 341, and the sound pickup channel 340 further includes at least part of the clearance space.

[0109] Or it can be understood that the surrounding area of the mounting hole 311 is provided with a mounting platform recessed from one side of the back of the housing 310 towards the front of the housing 310 for arranging the first waterproof sealing member 350. The side of the first waterproof sealing member 350 away from the center of the mounting hole 311 is the outer side of the first waterproof sealing member 350. The extension platform 312 is located in the surrounding portion of the mounting hole 311 and protrudes towards the center of the mounting hole 311 for arranging the sound pickup through hole 341, and the microphone 410 is sealed and connected through the waterproof sealing layer on one side of the front of the housing 310, and the first sealing member 360 is arranged on one side of the back of the housing 310 and located in the surrounding area of the sound pickup through hole 341. It should be noted that the extension platform 312 can be formed by protruding towards the center of the mounting hole 311 at any position in the surrounding area of the mounting hole 311 according to the flexible arrangement of the microphone 410, and the present application does not limit this.

[0110] The surrounding area of the mounting hole 311 on the housing 310 is provided with an extension platform 312 protruding towards the center of the mounting hole 311, and the sound pickup through hole 341 penetrates the extension platform 312. The extension platform 312 can be arranged at any position on the outer periphery of the mounting hole 311 for arranging the connected microphone 410, so that the microphone 410 is placed at a more free position inside the housing assembly 300, and the flexibility of the position design of the microphone 410 is increased. Correspondingly, the first waterproof sealing member 350 forms a concave structure along the outer periphery of the extension platform 312, that is, the waterproof sealing integrity between the camera decoration member 320 and the housing 310 is also ensured at the arrangement position of the microphone 410, and the risk of external liquid entering the internal space of the housing assembly 300 from the gap between the camera decoration member 320 and the housing 310 is reduced. Furthermore, a waterproof and breathable structure is usually arranged in the channel between the sound pickup port 330 and the microphone 410, so as to ensure that the sound outside the housing assembly 300 can normally enter through the sound pickup port 330 of the sound pickup channel 340, and be transmitted along the sound pickup channel 340 to the microphone 410 to realize sound collection, while avoiding the entry of external liquid into the internal space of the housing assembly 300 from the sound pickup through hole 341.

[0111] In a possible implementation, the orthographic projection of the decoration piece passage 342 to the back of the shell 310 is located on the outer circumferential side of the first waterproof seal 350. The other end of the decoration piece passage 342 is in communication with the sound pickup through hole 341 through the avoiding space, and part or all of the orthographic projection of the decoration piece passage 342 to the back of the shell 310 is located on the extension platform 312 of the shell 310, so that the path of the sound pickup passage 340 in the outer decoration piece 322 is shortened, the sound pickup stability is improved, meanwhile, the first waterproof seal 350 is prevented from being interrupted by the sound pickup passage 340, and the integrity of the waterproof seal of the electronic device is ensured.

[0112] As shown in FIGS. 7a and 7b, in a possible implementation, the shell assembly 300 further includes a first seal 360, which is annularly arranged on the outer circumferential side of the other end of the decoration piece passage 342 and the outer circumferential side of the sound pickup through hole 341 (i.e., between the outer decoration piece 322 and the front of the shell 310), and is sealingly connected between the back of the shell 310 and the outer decoration piece 322. When the shell assembly 300 has the avoiding space and the shell 310 has the extension platform 312, the first seal 360 is sealingly connected between the extension platform 312 of the shell 310 and the outer decoration piece 322 and located in the avoiding space. The first seal 360 ensures the sealing connection between the sound pickup through hole 341 of the shell 310 and the camera decoration piece 320, prevents sound waves from leaking at the connection between the camera decoration piece 320 and the shell 310, ensures the effective propagation of sound waves along a specific path, and achieves good sound pickup effect of the microphone 410. The specific form of the first seal 360 is not limited, for example, a glue layer, a sealing ring, foam and the like, which can be processed by means such as dispensing and back gluing.

[0113] Optionally, the sound pickup passage 340 in the outer decoration piece 322 can further include a plurality of sequentially connected and penetrating sub-passages.

[0114] It should be noted that the specific structure and setting position of the microphone assembly 400 are not limited. As shown in FIGS. 5, 7a and 10, the microphone assembly 400 further includes a flexible circuit board module 420, which is fixed and electrically connected with the microphone 410 and located between the circuit board of the microphone 410 and the front of the shell 310, and the side of the flexible circuit board module 420 away from the microphone 410 is sealingly connected with the front of the shell 310.

[0115] As shown in FIG. 10, in a possible implementation, the electronic device 100 further includes a bracket 500, the bracket 500 is arranged in the cavity of the shell assembly 300, and the microphone 410 is fixed to the bracket 500 through the flexible circuit board module 420. The microphone 410 is fixed and electrically connected with the flexible circuit board module 420, to realize transmission of an electrical signal. The microphone 410 is fixed on the bracket 500 through the flexible circuit board module 420, to prevent the microphone 410 from falling off inside the shell assembly 300, and to improve the stability of sound pickup of the microphone 410. The electronic device 100 can also not be provided with the bracket 500, which is not limited in the present application. The flexible circuit board module 420 and the shell 310 are connected in a sealed manner, for example, can be connected through bonding, welding and the like.

[0116] In a possible implementation, the electronic device 100 further includes a mainboard 600. The mainboard 600 and the microphone 410 are fixed to two sides of the bracket 500 respectively arranged opposite to each other. In the thickness direction of the shell assembly 300, the thickness of the microphone 410 can be multiplexed with the thickness of the electronic elements between the camera decoration 320 and the bracket 500, to facilitate reducing the thickness of the electronic device 100. The microphone 410 is fixed to the bracket 500 through the flexible circuit board module 420, and the microphone 410 is electrically connected with the mainboard 600 through the flexible circuit board module 420. The flexible circuit board module 420 is located between the front surface of the shell 310 and the microphone 410, to realize transmission of an electrical signal in the microphone 410. Optionally, the microphone 410 can be welded with the flexible circuit board module 420 through a welding process, and the flexible circuit board module 420 can be fixed to the bracket 500 through a gluing manner. It can be understood by those skilled in the art that the fixing manner between the microphone 410 and the flexible circuit board module 420, and between the flexible circuit board module 420 and the bracket 500 is not limited in the present application.

[0117] In a possible implementation, the projection of the microphone 410 of the microphone assembly 400 on the shell 310 in the thickness direction of the shell assembly 300 is located in the opening of the sound pickup through hole 341, or it can be understood that the sound pickup through hole 341 extends along a straight line parallel to the thickness direction of the shell assembly 300, and the microphone 410 is located directly below the sound pickup through hole 341. The vertical hole is arranged in the thickness direction of the shell assembly 300, which can effectively shorten the path of the sound pickup channel 340, and ensure the sound pickup effect of the microphone 410.

[0118] As shown in FIGS. 7a and 7b, in one possible implementation, the microphone assembly 400 is provided with a waterproof and breathable film 372, which is fixed to the housing 310 at a portion of the housing 310 surrounding the sound pickup hole 341 through a waterproof sealing layer 370, so as to prevent external liquid from leaking and protect the microphone 410 from water, salt and other corrosive liquids, thereby prolonging the service life of the microphone 410. It can be understood that the present application does not limit the arrangement of the waterproof and breathable film 372. The waterproof and breathable film 372 not only has the functions of waterproof and dustproof, but also allows sound to pass through, so as to ensure that the sound quality is not affected. For example, the waterproof sealing layer 370 can be provided as a glue layer or a sealing ring, which is achieved by processing methods such as back gluing and spot gluing, and the present application does not limit this.

[0119] In one possible implementation, a sealing foam 371 is arranged between the side of the flexible circuit board module 420 of the microphone assembly 400 away from the microphone 410 and the housing 310. The sealing foam 371 is arranged between the waterproof sealing layer 370 and the microphone assembly 400. In one possible implementation, the sealing foam 371 is an acoustic insulation foam. Since the acoustic insulation foam has a certain compression deformation amount, it can be compressed between the housing 310 and the microphone assembly 400 (for example, it can be compressed between the front surface of the housing 310 and the flexible circuit board module 420 through the waterproof sealing layer 370), so as to avoid external incoming sound waves from leaking into the inside of the housing assembly 300 at this position, thereby achieving good sealing and sound insulation effects. It can be understood that those skilled in the art can design waterproof sealing members according to actual needs to ensure the sealing performance of the electronic device 100, and the present application does not limit the number and position of the waterproof sealing members.

[0120] As shown in FIG. 10, in one possible implementation, the camera decoration piece 320 further includes a light-transmitting layer 324, which is mounted on the first decoration piece 3221 at a side away from the housing 310 and is used to cover the camera module 71, so as to prevent external sundries, dust and liquid from entering the camera decoration piece 320 and ensure the sealing performance of the electronic device 100. The light-transmitting layer 324 is made of a transparent material, for example, glass. The present application does not limit the material of the light-transmitting layer 324. In one possible embodiment, the sound pickup port 330 is arranged on the lateral surface of the camera decoration piece 320, and neither the sound pickup port 330 nor the sound pickup channel 340 is arranged on the light-transmitting layer 324, so as to avoid processing the light-transmitting layer 324, thereby reducing the cost of the electronic device 100. At the same time, the sound pickup channel 340 is led out from the side of the camera decoration piece 320, and when the light-transmitting layer 324 is mounted on the camera decoration piece 320, it is not necessary to align the mounting step of the through hole formed by the sound pickup channel 340 penetrating through the light-transmitting layer 324, thereby reducing the mounting time of the electronic device 100.

[0121] In order to better fix the lens, the light-transmitting layer 324 is fixed on the first decorative piece 3221 through a light-transmitting adhesive layer 325. The adhesive layer can be provided with a pre-set opening according to the arrangement of the camera module 71, so that external light fibers are incident on the camera module 71 through the opening. The light-transmitting adhesive layer 325 can be an adhesive or a solid adhesive (such as double-sided tape), and the present application is not limited in this regard.

[0122] As shown in FIG. 10, the outer decorative piece 322 is fixed and sealed to the shell 310 through a first waterproof sealing piece 350. The processing process and function of the first waterproof sealing piece 350 are not repeated here. The outer decorative piece 322 includes a first decorative piece 3221 and a second decorative piece 3222 stacked together. The first decorative piece 3221 is located away from the shell 310 on the side of the second decorative piece 3222. The first decorative piece 3221 and the second decorative piece 3222 are fixed and connected through a second waterproof sealing piece 380 to prevent external liquid from leaking into the camera decorative piece 320 and ensure the integrity of the waterproof seal of the entire machine. The second waterproof sealing piece 380 can be processed by means of dispensing and back gluing.

[0123] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
