The electronic device 10 of the embodiment of the present application may be a portable device such as a mobile phone, a tablet computer, a notebook computer, and a wearable device. The embodiment of the present application takes the electronic device 10 as a mobile phone as an example for description. The electronic device 10 includes a display module 11, a rear cover 12, a middle frame 13, and a microphone assembly 14, as shown in fig. 2. The display module 11 and the rear cover plate 12 are respectively connected with the middle frame 13, so that the display module 11 and the rear cover plate 12 form a basic structure for clamping the middle frame 13 together after being assembled, as shown in fig. 1. For example, the display module 11 and the rear cover plate 12 are respectively covered on two opposite surfaces of the middle frame 13 by one or a combination of assembling manners such as clamping, gluing, welding and the like. Further, a microphone assembly 14 and other structural members such as a battery, a main board, a camera module, a fingerprint module are disposed between the display module 11 and the rear cover 12, so that the electronic device 10 can perform corresponding functions.

In the embodiment of the present application, the back cover 12 and the middle frame 13 cooperate to form a gap 15, as shown in fig. 3, the gap 15 serves as a sound pickup hole of the microphone assembly 14. The gap 15 may be a minute gap, and the detailed structure will be described later. Compared with the prior art in which the sound pickup hole of the microphone is directly formed in the mobile phone shell, in the embodiment of the present application, the notch 15 is indirectly formed by the cooperation between the rear cover plate 12 and the middle frame 13, so that the notch 15 is used as the sound pickup hole of the microphone assembly 14, the concealment of the sound pickup hole can be increased, and the overall consistency of the electronic device 10 in appearance can be increased. Furthermore, the middle frame 13 is provided with a sound transmission channel which is communicated with the gap 15; the microphone assembly 14 is disposed at an end of the sound transmission channel away from the gap 15, so that the microphone assembly 14 can communicate with the external environment, and the detailed structure will be described later. Compared with the mode of assembling and matching the sound guide support (provided with the sound transmission channel of the microphone) and the mobile phone shell (provided with the sound pickup hole of the microphone) in the related art, the sound transmission channel communicated with the notch 15 is directly arranged on the middle frame 13 in the embodiment of the application, so that the microphone assembly 14 can pick up sound through the sound transmission channel and the notch, and thus, the sound guide support in the related art can be omitted, the manufacturing cost and the assembling cost of the electronic equipment 10 can be saved, the overall sealing performance of the sound transmission channel of the microphone assembly 14 can be increased, and the communication quality of the electronic equipment 10 can be increased.

The display module 11 may be a screen such as an lcd (liquid Crystal display), an OLED (Organic Light-Emitting Diode), a Mini-LED, or a Micro-LED. Generally, the display module 11 includes a display panel 111 and a transparent cover plate 112, as shown in fig. 2; the transparent cover 112 may be attached to the display panel 111 by using a sealant such as OCA (optical Clear Adhesive) or PSA (Pressure Sensitive Adhesive). The display panel 111 is mainly used for displaying a screen and serves as an interactive interface between a user and the electronic device 10. The transparent cover 112 may be tempered glass or a polyimide film, and is mainly used to protect the display panel 111 and serve as an outer surface of the electronic device 10, so that a user can perform touch operations such as clicking and sliding. In some other embodiments, the outer surface of the electronic device 10 (i.e., the outer surface of the transparent cover plate 112) may be further provided with any one of other functional film layers, such as a tempered film, a frosted film, a decoration film, a peep-proof film, a water condensation film, and the like, so that the electronic device 10 provides different use effects for users.

The rear cover 12 is a battery cover of the electronic device 10, and may be made of glass, metal, hard plastic, or other electrochromic materials. The back cover 12 has a structural strength that is primarily used to protect the electronic device 10 along with the transparent cover 112. Accordingly, the material of the middle frame 13 may be glass, metal, hard plastic, or the like. The middle frame 13 also has a certain structural strength, and is mainly used for supporting and fixing the microphone assembly 14 of the embodiment of the present application and other structural members such as a battery, a main board, a fingerprint module, a camera module, and the like. Further, since the rear cover plate 12 and the middle frame 13 are generally directly exposed to the external environment, the rear cover plate 12 and the middle frame 13 may preferably have certain wear-resistant, corrosion-resistant, scratch-resistant, and other properties, or the outer surfaces of the rear cover plate 12 and the middle frame 13 (i.e., the outer surfaces of the electronic device 10) may be coated with a layer of functional material for wear-resistant, corrosion-resistant, scratch-resistant. In some embodiments, the rear cover plate 12 and the middle frame 13 may be two separate structural members, as shown in fig. 1, and they may be assembled by one or a combination of clamping, gluing, welding, and the like. In other embodiments, the rear cover plate 12 and the middle frame 13 may also be integrally formed, such as by stamping, injection molding, etc.

Generally, the electronic device 10 may have a box-like appearance structure as a whole, that is, the display module 11, the rear cover 12 and the middle frame 13 may be rectangular. The display module 11 has four side edges, the rear cover plate 12 also has four side edges, and the middle frame 13 also has four side edges correspondingly; the two side edges of each structure are generally rounded to enhance the aesthetic appearance and grip of the electronic device 10. Further, at least one side edge of at least one of the display module 11 and the rear cover 12 connected to the middle frame 13 is a structure bent toward the middle frame 13. In other words, at least one of the four side edges of the display module 11 is bent toward the middle frame 13; and/or at least one of the four side edges of the rear cover plate 12 is bent toward the middle frame 13.

It should be noted that the side edges in the embodiment of the present application are a simple expression, and the width of the side edges is not considered, and the dimensions of the display module 11, the rear cover 12, and the middle frame 13 in the thickness direction of the electronic device 10 are not considered. Further, the side edges described in the embodiments of the present application should not be simply understood as lines in a general sense.

In some embodiments, the four side edges of the display module 11 and the four side edges of the rear cover plate 12 may be curved toward the middle frame 13, as shown in fig. 1 and fig. 2, that is, the side edges may be curved, and the effect of reducing or even hiding the width of the black edge of the display module 11 is achieved by four-side bending, so that a user can obtain a larger display view when using the electronic device 10. Further, in the embodiment of the present disclosure, the display module 11 and the rear cover 12 may have symmetrical structures with respect to the middle frame 13, as shown in fig. 1, so that a user can obtain better aesthetic appearance and grip feel when using the electronic device 10. In other embodiments, the display module 11 and the rear cover 12 may have a single-curved, double-curved, or triple-curved structure, or only one of the display module 11 and the rear cover 12 may have the curved structure. The electronic device 10 in the embodiment of the present application is described by taking a structure in which the display module 11 and the back cover 12 are all four-sided curved as an example. The electronic device 10 shown in fig. 1 and 2 only describes a portion (e.g., one quarter) of the display module 11, the rear cover 12 and the middle frame 13, and the structures of the other portions are the same as or similar to those in the drawings, and are not repeated herein. The specific structure of this quarter of the electronic device 10 is described in detail below.

With reference to fig. 1 to 3, the display module 11 includes a first straight portion 113 and a first curved portion 114, which are integrally formed, and the first curved portion 114 surrounds the first straight portion 113 and is in smooth transition with the first straight portion 113. The rear cover plate 12 includes a second straight portion 121 and a second curved portion 122, which are integrally formed, and the second curved portion 122 surrounds the second straight portion 121 and is in smooth transition with the second straight portion 121. The first bending portion 114 and the second bending portion 122 are both bent toward the middle frame 13, that is, the bending directions of the two portions are toward each other. Further, the first bending portion 114 and the second bending portion 122 can be connected to two opposite surfaces of the middle frame 13 by one or a combination of clamping, gluing, welding, and the like.

It should be noted that the integrally formed structure in the embodiment of the present application means that the structure of the product is an organic whole, and the product cannot be easily split or divided. For example: in the embodiment of the present invention, the tempered glass in a flat plate shape may be bent into the transparent cover plate 112 in the bent shape according to predetermined process parameters by using a hot bending technique, as shown in fig. 1 and 2, and the bent portion and the flat plate portion are naturally in a circular arc transition. The above process parameters can be reasonably designed according to factors such as the type of raw material, the bending angle and the curvature radius, and are not limited herein. Further, the OLED screen in a flat plate form may be attached to the transparent cover 112 to form the display panel 111 in the curved shape. Therefore, the line between the first straight portion 113 and the first curved portion 114 and the line between the second straight portion 121 and the second curved portion 122 in fig. 1 and 2 are only for illustrating the boundary between the above-mentioned portions. In other words, for the display panel 111 and the transparent cover plate 112 in an actual product, the lines are not true, i.e., the transition between the parts is smooth.

Further, the rear cover 12 of the embodiment of the present application is provided with a notch 123, and the notch 123 is specifically provided in the second bending portion 122, as shown in fig. 2, so that the rear cover 12 and the middle frame 13 cooperate to form a notch 15 at the notch 123, as shown in fig. 3, the notch 15 serves as a sound pickup hole of the microphone assembly 14. Wherein, the width of the notch 123 (i.e. the size of the gap between the rear cover plate 12 and the middle frame 13) may be 0.1-0.3 mm; preferably, the width may be 0.15-0.2mm, and the length of the notch 123 may be 3-4mm, that is, the notch 123 may be rectangular in appearance on the rear cover plate 12. Further, the depth of the notch 123 is determined to penetrate through the rear cover 12, so that the notch 15 formed by the rear cover 12 and the middle frame 13 at the notch 123 can be used as a sound pickup hole of the microphone assembly 14. With this arrangement, the notch 15 may be a narrow and long micro-gap in the appearance of the electronic device 10 for the user. Since the small gap is small, the small gap is not easily perceived by a user, and the concealment of the sound pickup hole can be increased, so that the overall consistency of the electronic device 10 in appearance can be increased. In other embodiments, the notches 123 may be saw-toothed, and include a series of micro-notches, which may be in one or more of a regular shape such as a semi-circle, a rectangle, a square, a triangle, etc. Furthermore, the rear cover plate 12 and the middle frame 13 may further be provided with functional members having grid-shaped holes at the notch 123, so that the sound pickup hole function of the notch 15 is not affected, and the waterproof and dustproof requirements of the electronic device 10 at the notch 15 can be met.

It should be noted that the notch 123 described in the embodiment of the present application may also be opened in the middle frame 13, or opened in both the back cover plate 12 and the middle frame 13, and the notch 15 may also be formed at the notch 123 by matching the middle frame 13 and the back cover plate 12.

The middle frame 13 includes a frame 131 and a middle plate 132, wherein the middle plate 132 is connected to the frame 131 and extends away from the frame 131. The frame 131 is mainly exposed to the external environment, has an appearance surface, and can play a decorative role; the middle plate 132 is located inside the electronic device 10, and can support and fix the microphone assembly 14. Further, the middle plate 132 and the side frame 131 may be integrally formed, that is, the middle frame 13 may be an integrally formed structural member, which can simplify the structure of the middle frame 13, thereby reducing the manufacturing cost of the middle frame 13. In other embodiments, the middle plate 132 and the frame 131 may be connected by one or a combination of clamping, gluing, and welding. In the embodiment of the present application, the frame 131 cooperates with the second bending portion 122 of the rear cover plate 12 to form the gap 15.

Referring to fig. 4 and 5 together, fig. 4 is a schematic partial enlarged structure view of a portion a in fig. 1, and fig. 5 is a schematic partial enlarged structure view of a portion B in fig. 2.

Based on the above detailed description, since the display module 11 and the rear cover 12 may be both curved structures that are curved toward the middle frame 13, when the display module 11, the rear cover 12 and the middle frame 13 are connected, an arc-shaped space is formed between the display module 11 and the rear cover 12. Therefore, one surface of the middle plate 132 close to the display module 11 may be a curved surface having the same or similar curvature radius as the display module 11 (specifically, the first bending portion 114), and one surface of the middle plate 132 close to the rear cover 12 may be a curved surface having the same or similar curvature radius as the rear cover 12 (specifically, the second bending portion 122), as shown in fig. 4 and 5, so that the middle plate 132 can better support the display module 11 and the rear cover 12 through the curved surface structure, thereby increasing the structural strength of the whole electronic device 10 and further increasing the reliability of the electronic device 10. In other embodiments, for example, when the curvature radius of the first curved portion 114 and the second curved portion 122 is larger, one surface of the middle plate 132 close to the display module 11 and the rear cover 12 may be a straight plane, so as to simplify the structure of the middle plate 132, and reduce the processing difficulty of the middle frame 13.

Furthermore, two sides of the border between the frame 131 and the middle plate 132 may be recessed to form a first groove 133 and a second groove 134. Wherein, the first groove 133 is close to the display module 11, and the second groove 134 is close to the rear cover 12, as shown in fig. 5; and the distance between the first groove 133 and the second groove 134 is smaller than the width of the outer surface of the frame 131 in the thickness direction of the electronic device 10, as shown in fig. 4, so that the display module 11 can extend to the first groove 133 along the curved surface of the middle plate 132, and the rear cover 12 can extend to the second groove 134 along the curved surface of the middle plate 132, as shown in fig. 5, so that the display module 11 and the rear cover 12 can be partially hidden in the middle frame 13. That is, the middle frame 13 can protect the edges of the display module 11 and the rear cover 12 to some extent, thereby increasing the reliability of the electronic device 10.

In the embodiment of the present application, the width of the appearance surface of the frame 131 in the thickness direction of the electronic device 10 is less than or equal to 1.8 mm; preferably, the width is greater than or equal to 1.4mm and less than or equal to 1.6mm, so that the display module 11 and the rear cover plate 12 can extend more toward each other along the middle plate 132, thereby enabling the electronic device 10 to obtain a larger display field of view. Accordingly, the appearance surface of the frame 131 may be a straight plane or an arc convex surface, so that the electronic device 10 can obtain better appearance and holding feeling. Further, the middle frame 13 is thinned from the inside to the outside of the electronic device 10 as a whole, as shown in fig. 4 and 5, so that the middle frame 13 can meet both requirements of ultra-thinning and structural strength, thereby increasing the reliability of the middle frame 13. Obviously, the ultra-thin middle frame 13 (especially the frame 131) is difficult to meet the requirement of directly forming the sound pickup hole on the mobile phone shell in the related art. For this purpose, the present application develops a new approach to indirectly form the sound pickup hole of the microphone assembly 14 by the back cover plate 12 cooperating with the middle frame 13, as mentioned above.

The specific structure of the microphone assembly 14 and its cooperation with the middle frame 13 will be described in detail below.

Referring to fig. 6 to 8 together, fig. 6 is a schematic cross-sectional structure of the electronic device in fig. 3 along the VI-VI direction, fig. 7 is a schematic cross-sectional structure of the middle frame in fig. 6, and fig. 8 is a schematic exploded structure of the electronic device in fig. 3. It should be noted that the electronic device shown in fig. 6 to 8 mainly includes partial structures related to the rear cover plate 12, the middle frame 13 and the microphone assembly 14; the display module 11 and its related structure are not shown.

In the embodiment of the present application, the microphone assembly 14 is disposed on a side of the middle plate 132 close to the back cover plate 12, as shown in fig. 6. The middle plate 132 defines a sound transmission channel, which extends to the microphone assembly 14 as shown in fig. 7. The sound transmission path of the microphone assembly 14 will be described in detail below.

A sound inlet 1322 is formed in the middle plate 132 near the first surface 1321 of the second bending portion 122 of the rear cover plate 12, as shown in fig. 7 and 8; the sound inlet 1322 communicates with the gap 15, as shown in fig. 6. The sound inlet 1322 according to the embodiment of the present disclosure may be expanded from the middle plate 132 to the frame 131, for example, the sound inlet 1322 is expanded from the first surface 1321 to the second groove 134 (i.e., the boundary between the frame 131 and the middle plate 132), as shown in fig. 8, so as to increase a communication area between the sound inlet 1322 and the gap 15, thereby increasing the sound pickup effect of the microphone assembly 15. Further, a sound outlet 1324 is opened on a second surface 1323 of the middle plate 132 close to the second straight portion 121 of the rear cover plate 12, as shown in fig. 7 and 8; the sound outlet 1324 is connected to the microphone assembly 14, as shown in fig. 6. Where second surface 1323 of middle plate 132 is much lower than first surface 1321, the space formed by the height difference can be used to place microphone assembly 14, so as to increase the compactness of electronic device 10 in structure. Further, a sound guiding slot 1326 is disposed on a third surface 1325 of the middle plate 132 away from the rear cover plate 12, as shown in fig. 7. Wherein, one end of the sound guiding slot 1326 extends to the sound inlet 1322; the other end of sound guiding groove 1326 extends to sound outlet 1324 so that middle plate 132 can form a sound transmission channel.

Further, the third surface 1325 may further be provided with a sealing pad 16, and the sealing pad 16 is disposed on the sound guide slot 1326 to seal the sound transmission channel formed by the middle plate 132, so as to increase the sound pickup effect of the microphone assembly 14. The sealing pad 16 may be made of PET (Polyethylene Terephthalate), and may be adhered to the third surface 1325 of the middle plate 132 by glue, foam, or the like, so that the sealing pad 16 seals the sound transmission channel formed by the middle plate 132. Further, the third surface 1325 may further have a sealing groove 1327, and the sealing groove 1327 is communicated with the sound guide groove 1326, as shown in fig. 7; the gasket 16 is provided in the sealing groove 1327, as shown in fig. 6, so that the gasket 16 can be covered on the sound guide groove 1326, which can seal the sound transmission path and increase the structural compactness of the electronic device 10.

In the embodiment of the present application, the middle plate 132 made of a hard plastic material and the frame 131 made of a metal material can be processed into the middle frame 13 of an integrated structure by using an injection molding manner, and the middle plate 132 can form the sound inlet 1322, the sound outlet 1324, and the sound guide slot 1326 by using a core setting manner, so as to satisfy the feasibility in the process. The frame 131 is made of a metal material, which not only can increase the aesthetic appearance of the middle frame 13, but also can increase the wear-resistant, corrosion-resistant, scratch-resistant, and other performances of the middle frame 13. Further, compared with the soft rubber material, the middle plate 132 of the embodiment of the present application is made of hard plastic, so that on one hand, the middle plate has better structural strength, and can improve the problem of sound transmission channel deformation caused by external force extrusion of the middle frame 13 in the assembling and using processes; on the other hand, the problem that burrs are easily formed in the sound transmission channel of the middle plate 132 in the injection molding process can be solved, so that the sound transmission effect of the sound transmission channel is increased, and the communication quality of the electronic device 10 is improved. In other embodiments, the sound inlet 1322 and the sound outlet 1324 of the middle frame 13 may also be formed by machining.

With continued reference to fig. 6-8, the microphone assembly 14 includes a motherboard 141 and a microphone 142 electrically connected to each other. The main board 141 is disposed on one side of the middle board 132 close to the rear cover plate 12, and is provided with a sound transmission through hole 1411, as shown in fig. 8; the microphone 142 is disposed on one side of the main board 141 close to the rear cover 12, and is communicated with the sound outlet 1324 of the middle plate 132 through the sound transmission through hole 1411, so that the microphone 142 can be communicated with the external environment through the sound transmission channel (mainly the sound guide slot 1326) formed by the middle plate 132 and the notch 15 formed by the rear cover 12 and the middle frame 13, as shown in fig. 6, so that the microphone 142 can pick up sound. In the embodiment of the present application, the microphone 142 may be first attached to the motherboard (or other circuit boards) 141 by a Surface Mounting Technology (SMT), and then the sealing ring 143 is used to realize the sealing connection between the motherboard 141 and the middle board 132, as shown in fig. 6, so as to meet the sealing requirement between the motherboard 141 and the middle board 132. The sealing ring 143 may be a sealing member such as foam or a silicone sleeve, or a sealing structure formed by curing such as glue or glue dispensing.

Generally, for a functional element such as a microphone, the function is mainly to pick up the voice of a user and convert the voice signal into an electric signal during the interaction of the user such as making a call, sending a voice message and chatting a video (including voice). Further, as the user demands higher and higher call quality during the above interaction process, two microphones are generally disposed in the electronic device 10, wherein one of the two microphones is mainly used for picking up the user sound (which may be referred to as a main microphone), and the other microphone is mainly used for picking up the environmental sound (which may be referred to as a secondary microphone). The electronic device 10 may perform denoising processing according to the user sound picked up by the primary microphone and the environmental sound picked up by the secondary microphone, so as to increase the resolution (reduction degree) of the electronic device 10 to the user sound, thereby increasing the call quality of the electronic device 10 and improving the user experience. Therefore, the microphone 142 according to the embodiment of the present application may be a main microphone of the electronic device 10, or may be a sub-microphone of the electronic device 10.

It is well known that the sealing of the acoustic channel is critical in order to ensure the speech quality of the electronic device 10. Therefore, in the embodiment of the present application, the sound transmission channel communicated with the notch 15 is directly opened in the middle frame 13, so that the microphone 142 can directly pick up sound through the sound transmission channel of the middle frame 13 and the notch 15 formed by matching the sound transmission channel with the rear cover plate 12 without using a sound guide bracket of the related art, thereby directly avoiding the problem of sealing property existing in the way of assembling and matching the sound guide bracket (in which the sound transmission channel of the microphone is opened) with the mobile phone shell (in which the sound pickup hole of the microphone is opened) in the related art, and further increasing the communication quality of the electronic device 10 in the whole structure.
