Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device and a sound receiving device. Background Art

[0002] With the continuous development of large-size screen technology, users have higher and higher requirements for the appearance of the screen, especially the appearance of the front of the screen. However, most screens are equipped with a far-field sound receiving device at the bottom for receiving external sounds, and the part of the far-field sound receiving device protruding from the bottom of the screen has a large height. When users watch movies normally, the far-field sound receiving device will also be included in the field of vision, reducing the visual experience. Utility Model Content

[0003] In view of this, the present application provides an electronic device to solve the problem in the above-mentioned prior art that the far-field sound receiving device protruding from the bottom of the screen is easily observed by the user, resulting in a decrease in the user's visual experience.

[0004] In a first aspect, an embodiment of the present application provides an electronic device, which includes a display module, a housing, and a sound receiving device. The display module includes a display surface. The housing covers the display module. The sound receiving device is connected to the housing, and the sound receiving device is used to receive sound in the external environment; the sound receiving device includes a first part and a second part, the first part is accommodated in the housing, the second part protrudes from the outer surface of the housing, and the second part is provided with a first sound pickup channel.

[0005] In this embodiment, the first part of the sound receiving device can be located in the shell, so that the shell can absorb the height of the first part of the sound receiving device, thereby reducing the height of the part of the sound receiving device that is exposed from the shell, that is, the height of the second part of the sound receiving device is the height of the sound receiving device that is exposed outside the shell. Therefore, when the user is watching a movie, the line between the user's eyes and the edge of the electronic device will not pass through the sound receiving device, that is, the user will not observe the sound receiving device during normal viewing, achieving the effect of "hiding" the sound receiving device and improving the user's viewing experience.

[0006] In a possible implementation, the first sound pickup channel includes a first end and a second end. Along a first direction, the cross-sectional area of ​​the first end is larger than the cross-sectional area of ​​the second end. The first direction is the direction from the first end to the second end. By making the cross-sectional area of ​​the first end relatively larger, the sound in the external environment can be more easily entered into the first sound pickup channel, and the sound entering the first sound pickup channel has a greater sound intensity, which is conducive to recognizing clear voice commands issued by the user.

[0007] In a possible implementation, the display module includes a display screen, the first end is closer to the display screen than the second end, and the first sound pickup channel is connected to the sound pickup component in the sound receiving device through the second end. Thus, the voice in front of the electronic device can be more easily received through the first end, which is conducive to clear recognition of the sound.

[0008] In a possible implementation, the cross-sectional area of ​​the first sound pickup channel gradually decreases in the direction from the first end to the second end. The space inside the first sound pickup channel for propagating sound gradually shrinks from the first end to the second end, that is, the first sound pickup channel has the largest cross-sectional area at the first end, and can receive more sound, which is beneficial to improve the received sound intensity, so that the sound receiving device can recognize clear voice commands.

[0009] In a possible implementation, the first end passes through the sound receiving device, thereby being able to receive voice commands in an external environment.

[0010] In a possible implementation, the sound receiving device further includes a second sound pickup channel, the second sound pickup channel is connected to the first sound pickup channel, and an end of the second sound pickup channel away from the first sound pickup channel is connected to a sound pickup component in the sound receiving device. The shapes and sizes of the first sound pickup channel and the second sound pickup channel can be designed separately, so that parameters such as the intensity and frequency of the sound can meet the requirements, ensuring that the sound receiving device can clearly recognize the voice command.

[0011] In a possible implementation, the second sound pickup channel extends along a second direction, and the second direction intersects the first direction. The first direction may be consistent with the thickness direction of the electronic device, or may have a certain angle with the thickness direction of the electronic device, so that the first end of the first sound pickup channel can face the side where the display screen 11 is located, so as to facilitate receiving voice commands in the environment in front of the electronic device.

[0012] In a possible implementation, the cross-sectional area of ​​the second sound pickup channel gradually decreases from the end close to the first sound pickup channel to the end away from the first sound pickup channel. The shape of the second sound pickup channel can be formed into a "horn" shape, and the end of the second sound pickup channel close to the first sound pickup channel has a larger cross-sectional area, which is conducive to receiving more sounds from the first sound pickup channel, and further conducive to improving the intensity of the sound in the second sound pickup channel, so that the sound pickup component can recognize clear sounds.

[0013] In a possible implementation, the first sound pickup channel and the second sound pickup channel are integrally formed. Exemplarily, the first sound pickup channel and the second sound pickup channel can both be formed on the cover, that is, during the manufacturing process of the cover, the first sound pickup channel and the second sound pickup channel can be integrally formed on the cover, thereby facilitating processing and saving costs.

[0014] Alternatively, the sound receiving device includes a first component and a second component, the first component is provided with the first sound pickup channel, the second component is provided with the second sound pickup channel, and the first component and the second component are fixedly connected so that the first sound pickup channel and the second sound pickup channel are connected. By adopting the first component and the second component connected in a split manner, the processing difficulty of the first sound pickup channel and the second sound pickup channel can be reduced.

[0015] In a possible implementation, the sound receiving device further includes a third sound pickup channel, the third sound pickup channel is connected to the second sound pickup channel, and one end of the third sound pickup channel away from the second sound pickup channel is connected to the sound pickup assembly. The third sound pickup channel can constrain the propagation direction of the sound, so that the sound can propagate to the fourth sound pickup channel along the extension direction of the third sound pickup channel, reduce the reflection of the sound in the channel, ensure the sound intensity, and reduce distortion. At the same time, the third sound pickup channel can adjust the frequency of the sound to the frequency required by the sound receiving device, thereby ensuring that the sound can be clearly identified.

[0016] In a possible implementation, the third sound pickup channel has the same cross-sectional area at each location along its extension direction, that is, the third sound pickup channel has a uniform inner diameter, and illustratively, the third sound pickup channel is a cylindrical channel. The third sound pickup channel can constrain the propagation direction of the sound, so that the sound can propagate to the fourth sound pickup channel along the extension direction of the third sound pickup channel, reduce the reflection of the sound in the channel, ensure the sound intensity, and reduce distortion.

[0017] In a possible implementation, the sound pickup assembly includes a circuit board and a sound pickup device, the sound pickup device is electrically connected to the circuit board, and the sound pickup device is used to receive the sound in the first sound pickup channel and the second sound pickup channel. The sound pickup assembly is used to receive and process sound signals. Exemplarily, the sound pickup device can be a device such as a microphone array, the microphone array can process and analyze voice signals, and the microphone array is electrically connected to the circuit board.

[0019] In a possible implementation, the thickness direction of the circuit board intersects with the thickness direction of the electronic device. Thus, the excessive space occupied by the circuit board in the height direction of the electronic device in the sound receiving device can be reduced, thereby reducing the height of the sound receiving device, making it easier for at least part of the sound receiving device to be accommodated in the body, and reducing the height of the part of the sound receiving device protruding from the outside of the shell, which can effectively prevent the user from observing the sound receiving device during normal viewing.

[0020] In a possible implementation, the sound receiving device includes a housing, the circuit board is connected to the housing, and the first sound pickup channel and the second sound pickup channel are arranged on the housing.

[0021] In a possible implementation, a sealing member is further included, one side of the sealing member abuts against the housing, and one side of the sealing member away from the housing abuts against the circuit board, and a through hole is provided on the sealing member, and the third sound pickup channel is connected to the fourth sound pickup channel through the through hole. The sealing member can seal the third sound pickup channel and the first sound pickup channel at the joint position, thereby preventing leakage of sound transmitted from the first sound pickup channel to the third sound pickup channel, thereby ensuring the strength of sound transmission and reducing distortion.

[0022] In a possible implementation, the sound receiving device further includes a stopper, the stopper is disposed on a side of the circuit board away from the housing, the stopper is connected to the housing, and the stopper abuts against the circuit board.

The back cover can be a battery cover, which can provide protection for many devices and structures between the display module and the back cover.

[0025] In a possible implementation, the display module includes a display screen, a control board and a flexible circuit board, and the display screen is electrically connected to the control board through the flexible circuit board. The sound receiving device is arranged on a side of the flexible circuit board away from the display screen. There is a large space between the flexible circuit board and the back cover, which can accommodate the sound receiving device. At the same time, the end of the flexible circuit board away from the display screen has a large distance from the display screen along the thickness direction of the electronic device, so that the sound receiving device can be away from the display screen. When the user is watching a movie normally, the line connecting the user's eyes and the edge of the electronic device will not pass through the sound receiving device, thereby avoiding the user from observing the sound receiving device during the normal viewing process, thereby improving the user experience.

[0026] In a possible implementation, the height of the second part protruding from the outer surface of the shell is between 2 mm and 3 mm.

[0027] In a possible implementation, the sound receiving device is disposed at the bottom of the electronic device. The bottom of the electronic device is a part that is not often seen, and by disposing the sound receiving device at the bottom of the electronic device, the appearance of the electronic device can be improved.

[0078] It should be understood that the term "and / or" used in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0079] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0080] With the continuous development of the form and technology of screens on electronic devices such as televisions and monitors, users have higher and higher requirements on the appearance of screens. Figure 1 is a structural diagram of an electronic device. Figure 1 The electronic device 100 is exemplarily shown as a TV. The TV may be in a shape similar to a rectangular parallelepiped, with a length direction X, a height direction Y, and a thickness direction Z. The upright posture of the TV is the posture in normal use, that is, the height direction Y of the TV is perpendicular to the ground plane, or has a certain angle with the ground plane. The electronic device 100 includes a display module 110, which may also be called a screen, for displaying content images.

[0081] Any device on an electronic device that is exposed outside the electronic device may affect the appearance of the screen. Figure 2 It is a partial cross-sectional view of an electronic device in the related art, such as Figure 2 As shown, a sound receiving device 120 may be provided at the bottom of the screen, and the sound receiving device 120 may be used to receive sounds in the external environment and implement corresponding functions through software in the electronic device.

[0082] The sound receiving device 120 is at the bottom of the electronic device and is located as a whole on the outside of the electronic device. The sound receiving device 120 has a sound channel 121 for receiving sounds in the external environment. The user usually issues voice commands in front of the electronic device. The front of the electronic device is the side of the electronic device with the display module 110. The "front of the electronic device" mentioned below refers to the side of the electronic device with the display module 110. The sound receiving device 120 can receive voice commands through the sound channel 121.

[0083] In order to ensure that the sound receiving device 120 has a good effect of receiving the ambient sound, Figure 2 As shown, the opening of the sound channel 121 may face the front of the electronic device, and the sound receiving device 120 is entirely close to the outer surface of the display module 110 , which is the surface of the display module 110 facing the user.

[0084] The sound receiving device 120 is provided with a circuit board 122, and the circuit board 122 may be provided with a device for receiving voice, such as a microphone array. When the sound channel 121 is a linear channel, in order to enable the sound in the sound channel 121 to be received by devices such as the microphone array on the circuit board 122, the circuit board 122 in the sound receiving device 120 needs to be placed vertically, that is, the thickness direction of the circuit board 122 is consistent with the thickness direction Z of the electronic device. Since the size of the circuit board 122 in the direction perpendicular to the thickness direction Z is much larger than the thickness size of the circuit board 122, when the circuit board 122 is placed vertically, the circuit board 122 needs to occupy a larger space in the height direction Y of the electronic device, which results in the sound receiving device 120 having a larger height dimension in the height direction Y of the electronic device as a whole, that is, the height dimension of the sound receiving device 120 protruding from the surface of the electronic device housing is larger.

[0085] Figure 3 It is a schematic diagram of a user watching a movie using an electronic device in the related art, such as Figure 3 As shown, taking the case where the sound receiving device 120 is arranged at the bottom of the electronic device as an example, when the user is watching a movie normally, the user is located in front of the electronic device, and a certain distance is maintained between the user and the electronic device. Since the height dimension of the sound receiving device 120 protruding from the bottom of the electronic device is relatively large, the height dimension of the sound receiving device 120 protruding from the bottom of the electronic device is usually 8mm~10mm. The line between the user's eyes and the bottom edge of the electronic device will pass through the sound receiving device 120, that is, the user will also observe the sound receiving device 120 while watching the movie, which reduces the viewing experience.

[0086] In order to prevent the user from observing the sound receiving device 120 while watching a movie, the overall height of the sound receiving device 120 can be reduced. For example, the circuit board 122 can be arranged horizontally, that is, the thickness direction Z of the circuit board 122 is perpendicular to the thickness direction Z of the electronic device, so that the height space occupied by the circuit board 122 can be reduced. However, this method has a very limited amount of reduction in the height of the sound receiving device 120, and it is difficult to prevent the user from observing the sound receiving device 120 while watching a movie.

[0087] In view of this, the electronic device provided in this embodiment solves the problem that the user may observe the far-field sound receiving device at the bottom of the electronic device when watching a movie normally. In the embodiment of the present application, when the user watches a movie normally, the geometric center of the user's eyes and the electronic device are on the same horizontal plane for exemplary description.

[0088] The electronic device provided in the embodiment of the present application may be a device having a display module, such as a television and a monitor. Figure 4 A partial cross-sectional view of an electronic device provided in an embodiment of the present application at a certain viewing angle, such as Figure 4 As shown, the electronic device includes a display module 110, a housing 2 and a sound receiving device 120. The display module 110 may include a display screen 11, and the display screen 11 is used to display a content screen. The display module 110 includes a display surface 111, and the display surface 111 is a surface on the display screen 11 facing the user side. Among them, the user can watch the screen through the display screen 11, and can also trigger and operate the corresponding function by touching the display screen 11.

[0089] The display module 110 may be connected to the housing 2. For example, at least a portion of the housing 2 may cover the side of the display module 110. For example, at least a portion of the housing 2 may serve as a frame 21 of the electronic device to protect the side of the display module 110. At least a portion of the housing 2 is located on a side of the electronic device away from the display module 110. For example, at least a portion of the housing 2 may serve as a back cover 22 of the electronic device to protect numerous structures and devices inside the electronic device.

[0090] like Figure 4 As shown, there is a large space between the housing 2 and the display screen 11, and the space can be used to arrange a large number of devices, such as a rubber frame 16, a diaphragm 12, a diffuser 13, a reflector 14, a back panel 15, etc. The rubber frame 16 can be supported between the display screen 11 and the back panel 15 to ensure a reliable connection between the display screen 11 and the back panel 15.

[0091] The back plate 15 may be made of metal material, and the back plate 15 may enhance the structural strength of the display screen 11 and reduce damage caused by accidental collisions, etc. The back plate 15 may also effectively dissipate heat and protect the internal components of the display screen 11. The back plate 15 may also improve the screen contrast and enhance the display effect.

[0092] The diffusion plate 13 can transform limited backlight into a uniformly distributed light source, ensuring that the image of the display module 110 is clear and has uniform brightness.

[0093] The diaphragm 12 can be connected to the diffuser 13, and mainly plays the role of protecting and enhancing the image quality. The diaphragm 12 can include a filter film, an anti-reflection film, etc., which can enhance the color expression and contrast of the picture, while reducing the interference of external light on the picture.

[0094] The reflective sheet 14 can guide the light to a desired direction and can also reduce the reflection of ambient light, thereby making the image on the display module 110 clear and easy to see.

[0095] The display module 110 also includes a control board 17, which can be a printed circuit board (PCB), and the control board 17 can be provided with a control chip, a driver chip, a power module, and an input / output port. The control chip can control and process the signal and circuit function of the display module 110. The driver chip can control the pixels in the display screen 11 so that it displays the desired image. The power module can provide an appropriate voltage to ensure that the display module 110 works normally. The input / output port can include a video input interface (such as HDMI, VGA, DVI, etc.) and other auxiliary interfaces (such as audio, USB, etc.). Among them, the display screen 11, the diaphragm 12, the diffuser 13, the reflector 14 and the back plate 15 can be arranged in sequence in the thickness direction Z of the display module 110.

[0096] The display screen 11 and the control board 17 can be electrically connected via a flexible printed circuit (FPC) 18. The flexible printed circuit 18 can be arranged on the side of the display module 110. One end of the flexible printed circuit 18 used for connecting with the control board 17 can be bent appropriately to adapt to the layout position of the control board 17 and avoid surrounding devices, structures, etc.

[0097] The housing 2 covers the side of the display module 110 , and can provide protection for each film layer and the flexible circuit board 18 in the display module 110 .

[0098] The sound receiving device 120 may include a far-field voice device that can receive sounds in the external environment. The sound receiving device 120 can achieve human-computer interaction through voice commands within a certain distance.

[0099] The sound receiving device 120 is connected to the housing 2 and is located on the side of the display module 110, that is, on the side of the electronic device. The side of the display module 110 is perpendicular to the thickness direction Z of the display module 110. For example, Figure 5 A front view of an electronic device provided in an embodiment of the present application, such as Figure 5As shown, the electronic device may be a rectangular parallelepiped, and the lateral direction of the electronic device includes a left side c, a right side d, a top a, and a bottom b. The sound receiving device 120 may be disposed on any of the left side c, the right side d, the top a, or the bottom b of the electronic device. In order to ensure that the sound receiving device 120 receives the sound in the external environment, the sound receiving device 120 may be disposed at the bottom b of the electronic device, and may be located in the middle of the bottom b. In addition, the bottom b of the electronic device is a part that is not often seen. By disposing the sound receiving device 120 at the bottom b of the electronic device, the appearance of the electronic device may also be improved.

[0100] Figure 6 A partial cross-sectional view of an electronic device provided in an embodiment of the present application at another viewing angle, such as Figure 6 As shown, the sound receiving device 120 includes a first part 3a and a second part 3b, and the first part 3a and the second part 3b are two parts of the sound receiving device 120 distributed along the height direction Y of the electronic device. The first part 3a is accommodated in the housing 2, and the second part 3b protrudes from the outer surface of the housing 2. For example, when the sound receiving device 120 is arranged at the bottom of the electronic device, the second part 3b protrudes from the outer surface of the housing 2 at the bottom of the electronic device. It should be noted that the first part 3a and the second part 3b are not two independent structures, but two parts on the sound receiving device 120, that is, the part of the sound receiving device 120 located inside the housing 2 is the first part 3a, and the part located outside the housing 2 is the second part 3b.

[0101] In this embodiment, Figure 6 As shown, the first part 3a of the sound receiving device 120 can be located in the housing 2, so that the housing 2 can absorb the height of the first part 3a of the sound receiving device 120, so that the height of the part of the sound receiving device 120 that is exposed from the housing 2 can be reduced, that is, the height of the second part 3b of the sound receiving device 120 is the height of the sound receiving device 120 that is exposed outside the housing 2. At the same time, the second part 3b of the sound receiving device 120 is away from the display surface 111 in the thickness direction Z of the electronic device, so that when the user is watching a movie, the line between the user's eyes and the edge of the electronic device will not pass through the sound receiving device 120, that is, the user will not observe the sound receiving device 120 during normal viewing, achieving the effect of "hiding" the sound receiving device 120 and improving the user's viewing experience.

[0102] Along the thickness direction Z of the electronic device, the sound receiving device 120 is arranged on the side of the flexible circuit board 18 away from the display screen 11. The side of the flexible circuit board 18 away from the display screen 11 has a large space, which can be used to accommodate the sound receiving device 120. Among them, along the thickness direction Z of the electronic device, the projection of the sound receiving device 120 at least partially overlaps with the projection of the display module 110, that is, the projection of the first part 3a located in the shell 2 can have an area that at least partially overlaps with the projection of the display module 110 in the thickness direction Z of the electronic device. There is a large space behind the display module 110, which can realize that the first part 3a with a large height is arranged in the space behind the display module 110, so that the height of the part of the sound receiving device 120 exposed outside the shell 2 can be reduced, which is conducive to achieving the effect of "hiding" the sound receiving device 120.

[0103] like Figure 6 As shown, along the thickness direction Z of the electronic device, a distance is maintained between the second portion 3b of the sound receiving device 120 and the display surface 111 of the display screen 11. The second portion 3b has a first sound pickup channel 34, and the sound channel can receive sounds in the external environment. The sound receiving device 120 has a sound pickup component, which is used to process voice signals. The first sound pickup channel 34 can be connected to the sound pickup component in the sound receiving device 120, and voice commands in the external environment can be received by the sound pickup component through the first sound pickup channel 34.

[0104] The first end 34a is closer to the display screen 11 than the second end 34b, so that the voice in front of the electronic device can be more easily received through the first end 34a, which is conducive to clear recognition of the sound.

[0105] Among them, after the first part 3a of the sound receiving device 120 is installed in the housing 2, in order to ensure that the sound receiving device 120 can normally obtain the sound in the external environment, the height of the second part 3b needs to be within a certain size range. If the height of the second part 3b protruding from the outer surface of the housing 2 is too large, the user can easily observe the sound receiving device 120 during normal viewing; if the height of the second part 3b protruding from the outer surface of the housing 2 is too small, it is difficult to set a larger caliber sound channel in the second part 3b, and it is difficult to receive clear voice.

[0106] To this end, in this embodiment, the sound receiving device 120 is set at the bottom of the electronic device as an example. Figure 6As shown, the height H1 of the second part 3b protruding from the outer surface of the housing 2 is between 2mm and 3mm. For example, the height H1 of the second part 3b protruding from the outer surface of the housing 2 can be 2mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm or 3mm. By making the height H1 of the second part 3b protruding from the outer surface of the housing 2 between 2mm and 3mm, it can be ensured that the sound channel on the second part 3b can receive clear voice, and at the same time, it can prevent the user from seeing the sound receiving device 120 during normal viewing, thereby improving the user's viewing experience.

[0107] Figure 7 is a schematic diagram of a user watching a movie using an electronic device in this embodiment. Figure 7 As shown, by locating a part of the sound receiving device 120 inside the housing 2, the height of the part of the sound receiving device 120 that is exposed outside the housing 2 can be reduced, which is conducive to achieving the "hiding" effect of the sound receiving device 120, and can prevent the user from seeing the sound receiving device 120 during normal viewing, thereby improving the user's viewing experience. In one embodiment, the sound receiving device 120 can also be fully embedded in the housing 2, that is, the sound receiving device 120 does not protrude from the housing 2, so that the sound receiving device 120 can be fully hidden in the housing 2. In this embodiment, the first end 34a of the first sound pickup channel 34 faces the side of the electronic device.

[0108] Figure 8 A partial cross-sectional view of an electronic device provided in another embodiment of the present application (without the sound receiving device 120 installed), such as Figure 8 As shown, as described above, the housing 2 may include a frame 21 and a back cover 22. The frame 21 may be wrapped around the side of the display module 110 to protect the side of the display module 110. The back cover 22 is provided on the side of the display module 110 away from the display surface 111. The back cover 22 may be a battery cover, which may provide protection for a number of devices and structures located between the display module 110 and the back cover 22. An accommodation space 23 is formed between the frame 21 and the back cover 22, and the first portion 3a may be accommodated in the accommodation space 23.

[0109] The frame 21 may include a first bending portion 211, which is bent toward the inside of the electronic device, so that a receiving space 23 is formed between the first bending portion 211 and the back cover 22, and the sound receiving device 120 may be installed in the receiving space 23 along the extension direction of the first bending portion 211, that is, the first portion 3a of the sound receiving device 120 may be located between the first bending portion 211 and the back cover 22. The first bending portion 211 may provide a guide for the installation of the sound receiving device 120, and may also prevent the sound receiving device 120 from shaking in the thickness direction Z of the electronic device.

[0110] like Figure 8 As shown, a limiting portion 211 a may be provided on the first bending portion 211 , and the limiting portion 211 a may limit the installation of the sound receiving device 120 , thereby ensuring that the sound receiving device 120 has a high position accuracy.

[0111] The frame 21 may further include a second bent portion 212, which is located at an end of the frame 21 away from the first bent portion 211. The first bent portion 211 may cover a portion of the display screen 11 near the edge, that is, along the thickness direction Z of the electronic device, the projection of the first bent portion 211 overlaps with the projection of the display screen 11. The second bent portion 212 may protect the edge area of ​​the display screen 11.

[0112] like Figure 8 As shown, a groove-shaped space 24 can be formed between the first bending portion 211 and the second bending portion 212, and part of the flexible circuit board 18 can be located in the groove-shaped space 24 between the first bending portion 211 and the second bending portion 212. The first bending portion 211 is located on the side of the flexible circuit board 18 away from the display screen 11, and there can be a large space between the first bending portion 211 and the back cover 22 for installing the sound receiving device 120. Therefore, the distance between the sound receiving device 120 and the display surface 111 of the display module 110 is approximately equivalent to the distance between the first bending portion 211 and the second bending portion 212. In order to enable the frame 21 to accommodate the flexible circuit board 18 and the edge areas of each film layer in the display module 110, there is a large distance between the first bending portion 211 and the second bending portion 212, that is, there is also a large distance between the sound receiving device 120 and the display surface 111. Therefore, when the user is watching a movie normally, the line connecting the user's eyes and the edge of the electronic device will not pass through the sound receiving device 120, thereby avoiding the user from observing the sound receiving device 120 during the normal viewing process, thereby improving the user experience.

[0113] Fig. 9 A cross-sectional view of a sound receiving device provided in one embodiment of the present application, such as Fig. 9 As shown, the sound receiving device 120 may include a housing 32 and a sound pickup assembly, and the sound pickup assembly is used to receive and process sound signals. Exemplarily, the sound pickup assembly includes a circuit board 122 and a sound pickup device 37, and the sound pickup device 37 may be a device such as a microphone array, and the microphone array can process and analyze voice signals, and the microphone array is electrically connected to the circuit board 122. The circuit board 122 can be connected to the housing 32. Among them, the housing 32 is a supporting structure, which is used to support various devices or structures in the sound receiving device 120, and can also provide protection. Exemplarily, the circuit board 122 can be connected to the housing 32 by screws, and can also be connected to the housing 32 by gluing or other methods.

[0114] like Fig. 9As shown, the circuit board 122 is provided with a fourth sound pickup channel 33, the cover 32 is provided with a first sound pickup channel 34, the fourth sound pickup channel 33 is connected to the first sound pickup channel 34, and a sound pickup device 37 such as a microphone array is aligned with the fourth sound pickup channel 33. Voice commands in the external environment can be received by the sound pickup device after passing through the first sound pickup channel 34 and the fourth sound pickup channel 33 in sequence.

[0115] like Fig. 9 As shown, the first sound pickup channel 34 includes a first end 34a and a second end 34b. The first end and the second end both pass through the sound receiving device 120, that is, the voice command in the external environment can enter the first sound pickup channel 34 through the first end 34a, and propagate to the sound pickup component after passing through the second end 34b, and can be received by a device such as a microphone array.

[0116] Along the first direction, the cross-sectional area of ​​the first end 34a is larger than the cross-sectional area of ​​the second end 34b. For example, the first direction is the direction from the first end to the second end, and the cross-sectional area of ​​the first end 34a and the cross-sectional area of ​​the second end 34b can be perpendicular to the first direction. By making the cross-sectional area of ​​the first end 34a relatively larger, the sound in the external environment can be more easily entered into the first sound pickup channel 34, and the sound entering the first sound pickup channel 34 has a greater sound intensity, which is conducive to recognizing clear voice commands issued by the user.

[0117] In one embodiment, if Fig. 9 As shown, the inner wall of the first sound pickup channel 34 can extend in a straight line. In some other embodiments, the inner wall of the first sound pickup channel 34 can be provided with steps, so that the inner wall of the first sound pickup channel 34 forms a stepped shape. Alternatively, the inner wall of the first sound pickup channel 34 is a curved surface. Among them, for the first sound pickup channels 34 of different shapes, by making the cross-sectional area of ​​the first end 34a larger than the cross-sectional area of ​​the second end 34b, it can be achieved that the sound transmitted into the first sound pickup channel 34 has a greater sound intensity and reduces distortion.

[0118] like Fig. 9 As shown, the cross-sectional area of ​​the first sound pickup channel 34 gradually decreases from the first end 34a to the second end 34b. In this embodiment, the space for propagating sound inside the first sound pickup channel 34 gradually shrinks from the first end 34a to the second end 34b, that is, the first sound pickup channel 34 has the largest cross-sectional area at the first end 34a, which can receive more sound, thereby facilitating the improvement of the received sound intensity, so that the sound receiving device 120 can recognize clear voice commands.

[0119] In one embodiment, the opening of the first sound pickup channel 34 faces the side where the display screen 11 is located, that is, the opening of the first sound pickup channel 34 faces the front of the electronic device, which is conducive to receiving voice commands in front of the electronic device.

[0120] In some other embodiments, the opening of the first sound pickup channel 34 may also be oriented toward the side of the electronic device, which is not limited in this embodiment.

[0121] Fig.10 A schematic diagram of the coordination of the first sound pickup channel, the second sound pickup channel and the fourth sound pickup channel provided in an embodiment of the present application is shown in FIG. Fig.10 As shown, the sound receiving device 120 also includes a second sound pickup channel 35, and the first sound pickup channel 34, the second sound pickup channel 35 and the fourth sound pickup channel 33 are connected in sequence. The first sound pickup channel 34 extends along a first direction, and the second sound pickup channel 35 extends along a second direction, and the first direction intersects with the second direction. Among them, the first direction can be consistent with the thickness direction Z of the electronic device, or it can have a certain angle with the thickness direction Z of the electronic device, so that the first end 34a of the first sound pickup channel 34 can face the side where the display screen 11 is located, so as to facilitate receiving voice commands in the environment in front of the electronic device. In this embodiment, the second end 34b of the first sound pickup channel 34 does not pass through the sound receiving device 120.

[0122] The second direction may be consistent with the height direction Y of the electronic device, or may have a certain angle with the height direction Y of the electronic device. The first sound pickup channel 34 and the second sound pickup channel 35 may be formed in an approximately "L" shape, so that when at least part of the sound receiving device 120 is disposed in the housing 2, the sound in the external environment can be received through the first sound pickup channel 34.

[0123] The extension direction of the fourth sound pickup channel 33 on the circuit board 122 may be consistent or nearly consistent with the thickness direction of the circuit board 122. In order to enable the fourth sound pickup channel 33 to communicate with the second sound pickup channel 35, the extension direction of the fourth sound pickup channel 33 may be consistent or nearly consistent with the extension direction of the second sound pickup channel 35. Thus, the circuit board 122 in the sound receiving device 120 may be arranged in a horizontal posture, that is, the thickness direction of the circuit board 122 is consistent or nearly consistent with the height direction Y of the electronic device, or it can also be understood that the thickness direction of the circuit board 122 intersects with the thickness direction Z of the electronic device. For example, the angle between the thickness direction of the circuit board 122 and the thickness direction Z of the electronic device may be any angle between 85° and 95°. In some other embodiments, the angle between the thickness direction of the circuit board 122 and the thickness direction Z of the electronic device may also be other angles, which is not limited in this embodiment.

[0124] Among them, the horizontal arrangement of the circuit board 122 can reduce the excessive space occupied by the circuit board 122 in the height direction Y of the electronic device inside the sound receiving device 120, thereby reducing the height of the sound receiving device 120, making it easier for at least part of the sound receiving device 120 to be accommodated in the body, while reducing the height of the part of the sound receiving device 120 protruding from the outside of the shell 2, which can effectively prevent the user from observing the sound receiving device 120 during normal viewing.

[0125] Both the first sound pickup channel 34 and the second sound pickup channel 35 can be formed on the cover shell 32 , that is, during the manufacturing process of the cover shell 32 , the first sound pickup channel 34 and the second sound pickup channel 35 can be integrally formed on the cover shell 32 , thereby facilitating processing and saving costs.

[0126] In some other embodiments, the sound receiving device 120 may include a first component and a second component, and the first component and the second component may be independently processed structures, and the first component and the second component may be fixedly connected by assembly. Exemplarily, the first component and the second component may be assembled into a cover 32. The first component is provided with a first sound pickup channel 34, and the second component is provided with a second sound pickup channel 35, so that the first sound pickup channel 34 and the second sound pickup channel 35 are connected. By adopting the first component and the second component connected in a split manner, the processing difficulty of the first sound pickup channel 34 and the second sound pickup channel 35 can be reduced.

[0127] like Fig.10 As shown, the cross-sectional area of ​​the second sound pickup channel 35 gradually decreases from the end close to the first sound pickup channel 34 to the end away from the first sound pickup channel 34. The shape of the second sound pickup channel 35 can be formed into a "horn" shape, and the end of the second sound pickup channel 35 close to the first sound pickup channel 34 has a larger cross-sectional area, which is conducive to receiving more sounds from the first sound pickup channel 34, and further conducive to improving the intensity of the sound in the second sound pickup channel 35, so that the sound pickup component can recognize clear sounds.

[0128] In one embodiment, the first sound pickup channel 34 may be of the aforementioned “horn” shape, or the second sound pickup channel 35 may be of the aforementioned “horn” shape, or both the first sound pickup channel 34 and the second sound pickup channel 35 may be of the aforementioned “horn” shape.

[0129] Fig.11 A schematic diagram of the coordination of the first sound pickup channel, the second sound pickup channel and the fourth sound pickup channel provided in another embodiment of the present application is shown in FIG. Fig.11 As shown, the second sound pickup channel 35 can be a straight channel with uniform cross-sectional dimensions, and only the first sound pickup channel 34 is a "horn" shaped channel. This structure can also increase the intensity of the sound entering each channel.

[0130] Fig.12 A schematic diagram of the coordination of the first sound pickup channel, the second sound pickup channel, the third sound pickup channel and the fourth sound pickup channel provided in an embodiment of the present application is shown in FIG. Fig.12 As shown, the cover 32 may be provided with a first sound pickup channel 34, a second sound pickup channel 35 and a third sound pickup channel 36, and the first sound pickup channel 34, the second sound pickup channel 35, the third sound pickup channel 36 and the fourth sound pickup channel 33 are connected in sequence. The first sound pickup channel 34 and the second sound pickup channel 35 may be in the aforementioned "horn" shape. The third sound pickup channel 36 may be in a linear shape, that is, the third sound pickup channel 36 has the same cross-sectional area at each location along its own extension direction, that is, the third sound pickup channel 36 has a uniform inner diameter. For example, the third sound pickup channel 36 is a cylindrical channel.

[0131] The third sound pickup channel 36 can be consistent with the extension direction of the fourth sound pickup channel 33. The third sound pickup channel 36 can constrain the propagation direction of the sound so that the sound can propagate to the fourth sound pickup channel 33 along the extension direction of the third sound pickup channel 36, thereby reducing the reflection of the sound in the channel, ensuring the sound intensity, and reducing distortion. At the same time, the third sound pickup channel 36 can adjust the frequency of the sound to the frequency required by the sound receiving device 120, thereby ensuring that the sound can be clearly identified.

[0132] like Fig.12 As shown, the electronic device further includes a seal 4, which may be foam, a soft rubber ring, etc. The housing 32 of the sound receiving device 120 may be provided with a first sound pickup channel 34, a second sound pickup channel 35, and a third sound pickup channel 36 that are connected in sequence. One side of the seal 4 abuts against the housing 32, and the side of the seal 4 away from the housing 32 abuts against the circuit board 122. The seal 4 is provided with a third through hole 41, and the fourth sound pickup channel 33 is connected to the third sound pickup channel 36 through the third through hole 41. The seal 4 can seal the fourth sound pickup channel 33 and the third sound pickup channel 36 at the docking position, which can avoid the leakage of the sound propagated from the third sound pickup channel 36 to the fourth sound pickup channel 33, thereby ensuring the strength of sound transmission and reducing distortion.

[0133] Fig.13 A cross-sectional view of a sound receiving device provided in another embodiment of the present application, such as Fig.13As shown, the sound receiving device 120 includes a housing 32 and a circuit board 122, and the circuit board 122 is arranged on the housing 32.
