Description

electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202410565330.9, filed on May 8, 2024, entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and more particularly to an electronic device. Background Technology

[0003] Microphones (MICs) are important sound pickup devices and are widely used in electronic devices. Microphones are usually located inside electronic devices. In order to realize the microphone's sound pickup function, a pickup channel is usually opened on the electronic device. The location of this pickup channel matches the location of the microphone. Sound from outside the electronic device can enter the internal part of the electronic device through this pickup channel and be transmitted into the microphone.

[0004] However, current microphone pickup channels typically have only one entrance. When this entrance is located on the side of the electronic device, users may easily block it during use, causing the microphone to malfunction. Summary of the Invention

[0005] To address the aforementioned issues, this application provides an electronic device that, by increasing the number of entry points to two inlets in the microphone pickup channel and adjusting the relative positions of the two inlets, makes it difficult for users to completely block both inlets of the microphone pickup channel simultaneously when using the electronic device. This effectively reduces the risk of clogging and improves the microphone pickup performance.

[0006] In a first aspect, this application provides an electronic device including a first housing, a second housing, a first microphone assembly, and a display screen. The display screen and the first microphone assembly are supported on the first housing. The second housing surrounds the display screen and is connected to the first housing. At least a portion of the second housing is located on the side of the display screen facing away from the first housing and covers the edge of the display screen.

[0007] The electronic device is also provided with a first sound pickup channel, which includes a first inlet and a second inlet. The first inlet and the second inlet are respectively connected to the outside of the electronic device. The first inlet is located on the first side of the electronic device and is surrounded by a first housing. The second inlet is surrounded by the first housing and / or the second housing. The outlet of the first sound pickup channel is connected to a first microphone assembly.

[0008] Along the first direction, the orthographic projection of the second entrance on the first plane is closer to the first microphone assembly than the orthographic projection of the first entrance on the first plane. The first plane is the plane containing the length direction and the width direction of the electronic device. The first direction is the direction from the first side to the other side that is opposite to it.

[0009] In the aforementioned electronic device, since the first and second inlets are staggered, the probability of a user completely blocking both the first and second inlets simultaneously when using the electronic device is relatively small, effectively reducing the risk of clogging and thus enhancing the sound pickup performance of the first microphone assembly.

[0010] In one possible implementation of the first aspect, the second inlet is positioned closer to the display screen than the first inlet along the thickness direction of the electronic device. This further reduces the risk of the second inlet becoming blocked, thereby improving the sound pickup performance of the first microphone assembly.

[0011] In one possible implementation of the first aspect, the second entrance is located on the first side.

[0012] In one possible implementation of the first aspect, the area of ​​the second entrance projected onto the first plane is zero. Thus, when a user observes the electronic device from the side where the display screen is located, the second entrance is completely invisible. Consequently, other internal components of the electronic device cannot be observed through the second entrance, effectively improving the aesthetics and sophistication of the electronic device.

[0013] In one possible implementation of the first aspect, a notch is provided on the surface of the second housing facing the first housing along the thickness direction of the electronic device, and the notch and the first housing together form a second entrance.

[0014] It can be understood that, along the thickness direction of the electronic device, the surface of the second housing facing the first housing is the inner surface of the second housing. When a user observes the electronic device from the side where the display screen is located, they can see the outer surface of the second housing, but cannot see the inner surface of the second housing, and therefore cannot see the notch opened on the inner surface of the second housing, which can effectively improve the aesthetics and sophistication of the electronic device.

[0015] In addition, by creating a notch in the second housing and then using the notch and the first housing to form the second entrance of the first pickup channel, it is easy to form a smaller second entrance. This allows the second entrance to be set as a tiny slit structure, thereby further reducing the impact of setting the second entrance on the appearance of the electronic device and improving the aesthetics and sophistication of the electronic device.

[0016] In one possible implementation of the first aspect, the first pickup channel segment includes a first channel segment and a second channel segment, the entrance of the second channel segment constitutes a second entrance, the exit of the second channel segment is connected to the first channel segment, and the extension direction of the first channel segment intersects the extension direction of the second channel segment.

[0017] In other words, no straight line outside the electronic device can pass through the second entrance, the second channel segment, or the first channel segment to enter the interior of the electronic device. Thus, when a user observes the interior of the electronic device through the second entrance, they can only observe the channel surface of the first channel segment and / or the channel surface of the second channel segment from any angle, without observing other internal components and structures, effectively improving the aesthetics and sophistication of the electronic device.

[0018] In one possible implementation of the first aspect, the second entrance is rectangular in shape. This allows the second entrance to be made as narrow as possible, making it difficult for the user to observe its presence, thereby improving the aesthetics and sophistication of the electronic device.

[0019] In one possible implementation of the first aspect, the length of the second inlet is 3mm to 5mm, for example, 3mm, 4mm, 5mm, etc. In this way, the second inlet can be set as small as possible while ensuring the sound pickup effect of the first microphone assembly, thereby reducing the impact of the second inlet on the appearance of the electronic device and improving its aesthetics and sophistication.

[0020] In one possible implementation of the first aspect, the width of the second inlet is 0.1mm to 0.2mm, for example, 0.1mm, 0.15mm, 0.2mm, etc. In this way, the second inlet can be set as small as possible while ensuring the sound pickup effect of the first microphone assembly, thereby reducing the impact of the second inlet on the appearance of the electronic device and improving its aesthetics and sophistication.

[0021] In one possible implementation of the first aspect, the first side is the left or right side of the electronic device in its width direction.

[0022] In one possible implementation of the first aspect, the electronic device includes a second microphone assembly and a second pickup channel. The entrance of the second pickup channel is located on a second side of the peripheral side of the electronic device, the second side being adjacent to the first side, and the exit of the second pickup channel is connected to the second microphone assembly, which is supported on a first housing.

[0023] Based on this, the combination of the first microphone assembly and the second microphone assembly can realize the breath wake-up function of electronic devices, with low risk of clogging the hole and excellent sound pickup performance of the first microphone assembly.

[0024] In one possible implementation of the first aspect, the first side is the left or right side of the electronic device in its width direction, and the second side is the top or bottom of the electronic device in its length direction.

[0025] In one possible implementation of the first aspect, the electronic device includes a first body and a second body, which are rotatable relative to each other to fold or flatten the electronic device. The housing of one of the first and second bodies comprises a first housing and a second housing.

[0026] Based on this, the combination of the first microphone assembly and the second microphone assembly can realize the breath wake-up function of electronic devices, with low risk of clogging the hole and excellent sound pickup performance of the first microphone assembly.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0037] This application provides an electronic device, which may include, but is not limited to, mobile phones (e.g., foldable phones, candybar phones), tablet computers, laptops, ultra-mobile personal computers (UMPCs), handheld computers, netbooks, personal digital assistants (PDAs), wearable devices, virtual reality devices, and other electronic devices with microphones. For ease of explanation, the following description uses a foldable phone as an example. Furthermore, for ease of description, the state of a foldable phone after it is folded is defined as the folded state, the state of a foldable phone after it is unfolded is defined as the unfolded state, and the state of a foldable phone between the folded and unfolded states is defined as the intermediate state (or, hovering state).

[0038] Figures 1A to 1C show schematic diagrams of the structure of a foldable phone 1a according to an embodiment of this application. Figure 1A shows the foldable phone 1a in its flattened state, Figure 1B shows a cross-sectional view of a portion of the structure of the foldable phone 1a along section AA in Figure 1A, and Figure 1C shows the foldable phone 1a in its folded state.

[0039] For ease of description, before introducing the specific structure of the foldable phone 1a, we first define the X-axis, Y-axis, and Z-axis directions of the foldable phone 1a in conjunction with Figure 1A. As shown in Figure 1A, the X-axis direction is the length direction of the foldable phone 1a in its flattened state. For example, when the foldable phone 1a is flattened, the direction from the top 101 to the bottom 102 is the positive X-axis direction. The Y-axis direction is the width direction of the foldable phone 1a in its flattened state. For example, when the foldable phone 1a is flattened, the direction from the left side 103 to the right side 104 is the positive Y-axis direction. The Z-axis direction is the thickness direction of the foldable phone 1a in its flattened state. For example, when the foldable phone 1a is flattened, the direction from the back to the front is the positive Z-axis direction. In some embodiments of this application, the X-axis, Y-axis, and Z-axis directions intersect each other. In some implementations, the X-axis, Y-axis, and Z-axis directions can be perpendicular to each other.

[0040] It is understood that the perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to factors such as processing errors and assembly errors (e.g., the included angle between two structural features is 92°, 89.9°, 89°, 88°, etc.) is also within the scope of mutual perpendicularity in this application. The limitation of mutual perpendicularity will not be repeated below. Similarly, the parallelism in this application is not absolute parallelism. Approximate parallelism due to factors such as processing errors and assembly errors (e.g., the included angle between two structural features is 181°, 179.8°, 179°, 178°, etc.) is also within the scope of mutual parallelism in this application. The limitation of mutual parallelism will not be repeated below.

[0041] Referring to Figures 1A to 1C, the foldable phone 1a includes a first body 10, a second body 20, a hinge 30, and a display screen 40. The first body 10 and the second body 20 are respectively disposed on opposite sides of the hinge 30 and connected to it to achieve a rotatable connection. The display screen 40 is fixed to the first body 10, the second body 20, and the hinge 30. Exemplarily, the first body 10, the second body 20, and the hinge 30 are covered by the display screen 40. The first body 10 and the second body 20 can rotate relative to each other via the hinge 30, and can cause the display screen 40 to bend or flatten, thereby allowing the foldable phone 1a to switch between the flattened state shown in Figure 1A and the folded state shown in Figure 1C.

[0042] The first main body 10 of the foldable phone 1a is provided with a first microphone assembly 50 and a second microphone assembly 60 to realize the breath wake-up function of the foldable phone 1a in the folded state.

[0043] Specifically, the first microphone assembly 50 is positioned near the left side 103 of the foldable phone 1a. To enable the first microphone assembly 50 to pick up sound, the foldable phone 1a also has a first sound pickup channel 500a. Referring again to FIG1B and in conjunction with FIG1A, in some embodiments, the first body 10 includes a mid-frame 11a. The first sound pickup channel 500a is enclosed by the mid-frame 11a, and for example, the extension trajectory of the first sound pickup channel 500a is shown by a dashed line in FIG1B. The first sound pickup channel 500a connects the first microphone assembly 50 and the exterior of the foldable phone 1a. The entrance 501a of the first sound pickup channel 500a is located on the left side 103 of the foldable phone 1a and is connected to the exterior of the foldable phone 1a. The exit 502a of the first sound pickup channel 500a is located inside the foldable phone 1a and is connected to the first microphone assembly 50 located inside the foldable phone 1a. Thus, the first microphone assembly 50 can pick up sound from outside the foldable phone 1a through the first sound pickup channel 500a.

[0044] It is understood that the inlet of a pickup channel refers to the port on the pickup channel away from the microphone assembly, and the outlet of a pickup channel refers to the port on the pickup channel closer to the microphone assembly. For example, a pickup channel includes a first port and a second port. The first port is connected to the outside, and the second port is connected to the microphone assembly. In this case, the first port is the inlet, and the second port is the outlet. The concepts of inlet and outlet of a pickup channel will not be repeatedly defined below. Additionally, it is understood that the left side portion 103 of the foldable phone 1a includes at least a portion of the structure of the first mid-frame 11a.

[0045] The second microphone assembly 60 is positioned near the top 101 of the foldable phone 1a. Correspondingly, the foldable phone 1a has a second microphone channel 600, the entrance (not shown) of which is located at the top 101 of the foldable phone 1a and connected to the outside of the foldable phone 1a. The exit (not shown) of the second microphone channel 600 is connected to the second microphone assembly 60 located inside the foldable phone 1a. Thus, the second microphone assembly 60 can pick up sound from outside the foldable phone 1a through the second microphone channel 600.

[0046] Referring to Figures 1A and 1C, it can be seen that whether the foldable phone 1a is in its unfolded or folded state, the pickup paths of the first microphone assembly 50 and the second microphone assembly 60 have a positional difference in the X-axis direction. Therefore, the sound signal picked up by the first microphone assembly 50 and the sound signal picked up by the second microphone assembly 60 have a phase difference in the X-axis direction. In this way, the foldable phone 1a in its folded state can extract the first breath feature generated when the user speaks near the foldable phone 1a based on the sound signal picked up by the first microphone assembly 50, and extract the second breath feature generated when the user speaks near the foldable phone 1a based on the sound signal picked up by the second microphone assembly 60. Finally, breath wake-up is achieved based on the first and second breath features. For example, when the user speaks a voice interaction command near the foldable phone 1a, the foldable phone 1a can extract the user's first and second breath features, then enter the breath wake-up mode and perform operations according to the voice interaction command. For example, users can say "How's the weather today?" to wake up the voice assistant and get weather information without having to do anything else. For example, using a dedicated wake word to wake up the voice assistant or long-pressing the power button can effectively improve the continuity of human-computer interaction.

[0047] It is worth noting that since the entrance 501a of the first microphone channel 500a is located on the left side 103 of the foldable phone 1a, and users typically hold the foldable phone 1a with their hands on the left side 103, it is extremely easy to block the entrance 501a of the first microphone channel 500a. This can cause abnormal microphone pickup function of the first microphone assembly 50, thereby affecting the breath wake-up function of the foldable phone 1a. For example, with a blockage risk exceeding 50%, the success rate of breath wake-up when holding the foldable phone 1a with the left hand is only 70%, and the success rate when holding the foldable phone 1a with the right hand is only 45%. The high risk of blockage results in a low success rate of breath wake-up.

[0048] To address the aforementioned issues, this application provides a foldable mobile phone. The first microphone channel of this foldable phone includes two entrances. By adjusting the relative positions of these two entrances, it becomes difficult for a user to completely block both entrances simultaneously when using the foldable phone. This effectively reduces the risk of clogging, improves the microphone performance of the first microphone assembly, and consequently increases the success rate of breath-activated wake-up on the foldable phone. The technical solution of this application is described below with reference to the accompanying drawings.

[0049] Figures 2A and 2B show schematic diagrams of the structure of the foldable phone 1 in the embodiments of this application. Figure 2A shows the foldable phone 1 in its flattened state, and Figure 2B shows a cross-sectional view of a portion of the structure of the foldable phone 1 in section BB of Figure 2A.

[0050] Referring to Figures 2A and 2B, the foldable phone 1 includes a mid-frame 11 (as an example of a first housing), a cover 12 (or "small A-shell", as an example of a second housing), a display screen 40, and a first microphone assembly 50.

[0051] The mid-frame 11 supports the display screen 40 and the first microphone assembly 50. In some embodiments of this application, due to the requirements of overall appearance and folding, the display screen 40 cannot be directly bonded to the mid-frame 11 by adhesive, and a gap is formed between the display screen 40 and the mid-frame 11. In this application, the gap formed between the display screen 40 and the mid-frame 11 refers to the gap between the periphery of the display screen 40 and the periphery of the mid-frame 11 when the user observes the folded phone 1 along the Z-axis from the side where the display screen 40 is located, such as the gap shown in Figure 2B. Referring to Figures 2A and 2B, the cover 12 surrounds the edge of the display screen 40 and is connected to the mid-frame 11. Furthermore, at least a portion of the cover 12 is located on the side of the display screen 40 facing away from the mid-frame 11 and covers the edge of the display screen 40. In this way, the cover 12 can cover the gap between the display screen 40 and the mid-frame 11, thereby making the folded phone 1 more aesthetically pleasing while meeting the installation requirements of the display screen 40.

[0052] The foldable phone 1 also has a first microphone channel 500. The first microphone channel 500 connects the first microphone assembly 50 and the outside of the foldable phone 1, and is used to realize the microphone function of the first microphone assembly 50.

[0053] Specifically, the first pickup channel 500 has a Y-shaped fork structure, including two inlets and one outlet.

[0054] The first sound pickup channel 500 has two entrances, namely the first entrance 511 and the second entrance 521. The first entrance 511 and the second entrance 521 are respectively located on the outer surface of the foldable phone 1 and connected to the outside of the foldable phone 1. That is to say, the user can observe and touch the first entrance 511 and the second entrance 521 from the outside of the foldable phone 1.

[0055] The first entry point 511 is located on a first side of the four sides of the foldable phone 1. The four sides of the foldable phone 1 refer to the top (e.g., top 101), bottom (e.g., bottom 102), left side (e.g., left side 103), and right side (e.g., right side 104) of the foldable phone 1 when viewed from the side where the display screen 40 is located. The following description uses the left side 103 as an example of the first side to continue the description of the embodiments of this application.

[0056] The first entrance 511 is located on the left side portion 103. This can also be understood as the area of ​​the first entrance 511 projected onto the XZ plane being greater than 0. The first entrance 511 is enclosed by the middle frame 11. It can be understood that the left side portion 103 of the folding phone 1 includes at least a portion of the middle frame 11, which encloses the first entrance 511.

[0057] The second inlet 521 is enclosed by the middle frame 11 and / or the cover 12. For example, Figures 2A and 2B illustrate this by showing the second inlet 521 enclosed by the middle frame 11 and the cover 12. Along the Y-axis direction (as an example of the first direction), the orthographic projection of the second inlet 521 onto the XY plane (as an example of the first plane) is closer to the first microphone assembly 50 than the orthographic projection of the first inlet 511 onto the XY plane. That is, the first inlet 511 and the second inlet 521 are offset in the Y-axis direction.

[0058] The outlet 502 of the first pickup channel 500 is located inside the folding phone 1 and is connected to the first microphone assembly 50 inside the folding phone 1.

[0059] Based on this, the first microphone assembly 50 can have two sound pickup paths: a first sound pickup path 510 and a second sound pickup path 520. The first sound pickup path 510 can be, for example, the path shown by the dotted line in Figure 2B. Along the first sound pickup path 510, sound from outside the foldable phone 1 can be transmitted from the first inlet 511 to the outlet 502, and finally picked up by the first microphone assembly 50. The second sound pickup path 520 can be, for example, the path shown by the double-dotted line in Figure 2B. Along the second sound pickup path 520, sound from outside the foldable phone 1 can be transmitted from the second inlet 521 to the outlet 502, and finally picked up by the first microphone assembly 50.

[0060] In the aforementioned foldable phone 1, since the first inlet 511 and the second inlet 521 are staggered along the Y-axis, the probability of a user completely blocking both inlets 511 and 521 simultaneously is low, effectively reducing the risk of clogging and thus enhancing the sound pickup performance of the first microphone assembly 50. Consequently, the breath wake-up success rate of the foldable phone 1 is effectively improved. For example, compared to the solutions shown in Figures 1A to 1C, the breath wake-up success rate of the foldable phone 1 provided by this application can be increased from 70% for left-hand holding and 45% for right-hand holding to 90% for both hands, resulting in a better user experience.

[0061] Referring again to Figure 2B, in some embodiments of this application, along the Z-axis, the second entry 521 is closer to the display screen 40 than the first entry 511. Typically, when a user uses the foldable phone 1, the display screen 40 faces the user, and the back of the foldable phone 1 faces away from the user. The user's palm covers the back of the foldable phone 1, with fingers extending from the back to the front, i.e., the side where the display screen 40 is located. It is understood that, based on common user grip habits, along the Z-axis, the closer the sides of the foldable phone 1 are to the display screen 40, the less likely they are to be covered by fingers. Therefore, placing the second entry 521 closer to the display screen 40 can further reduce the risk of the second entry 521 becoming blocked, thereby improving the sound pickup performance of the first microphone assembly 50.

[0062] Referring again to Figure 2B, in some embodiments of this application, the second entrance 521 may be located on the same side of the folding phone 1 as the first entrance 511. For example, in this embodiment, the second entrance 521 and the first entrance 511 are located on the left side 103 of the folding phone 1. It can also be understood that the area of ​​the second entrance 521 projected onto the XZ plane is greater than 0.

[0063] Furthermore, in some embodiments of this application, the area of ​​the second entrance 521 projected onto the XY plane is 0. Thus, when a user observes the foldable phone 1 from the side where the display screen 40 is located (e.g., along the negative Z-axis), the second entrance 521 is completely invisible. Therefore, other components inside the foldable phone 1 cannot be observed through the second entrance 521, effectively improving the aesthetics and refinement of the foldable phone 1.

[0064] It is understandable that the second entrance 521 of the first pickup channel 500 can be distributed in various ways on the middle frame 11 and the cover 12.

[0065] In some embodiments of this application, the second entrance 521 of the first pickup channel 500 is formed by the middle frame 11 and the cover 12. Alternatively, the second entrance 521 of the first pickup channel 500 is formed on the middle frame 11 and the cover 12. The following will describe this in detail with reference to the accompanying drawings.

[0066] Figures 3A to 3C show side views of a portion of the structure of a foldable phone 1 in some embodiments of this application. Referring to Figure 3A, in some implementations, a notch 121 is formed on the first surface 12A of the cover 12, as shown in the light gray area enclosed by the dashed line in Figure 3A. The notch 121 and the surface of the middle frame 11 facing the notch 121 together form the second entrance 521 of the first pickup channel 500. The first surface 12A of the cover 12 is the surface of the cover 12 opposite to the middle frame 11 along the Z-axis. Alternatively, the first surface 12A of the cover 12 is the inner surface of the cover 12, meaning that the first surface 12A of the cover 12 cannot be directly observed from the outside of the foldable phone 1.

[0067] It is understandable that when a user observes the foldable phone 1 from the side where the display screen 40 is located (for example, observing along the negative Z-axis), the second surface 12B of the cover 12, that is, the outer surface of the cover 12, can be observed, but the first surface 12A of the cover 12 cannot be observed, and thus the notch 121 opened on the first surface 12A of the cover 12 cannot be observed, which can effectively improve the appearance and refinement of the foldable phone 1.

[0068] In addition, by opening a notch 121 on the cover 12, and then forming a second entrance 521 of the first sound pickup channel 500 together with the notch 121 and the middle frame 11, it is easy to form a smaller second entrance 521 along the Z-axis direction. This is beneficial to setting the second entrance 521 as a tiny slit structure, thereby further reducing the impact of setting the second entrance 521 on the appearance of the folding phone 1 and improving the aesthetics and refinement of the folding phone 1.

[0069] Referring to Figure 3B, in some alternative implementations, a notch 111 is provided on the middle frame 11, as shown in the dark gray area enclosed by the dashed line in Figure 3B. The notch 111 and the surface of the cover 12 facing the notch 111 together form the second entrance 521 of the first pickup channel 500.

[0070] Referring to Figure 3C, in some alternative implementations, the middle frame 11 has a notch 111, as shown in the dark gray area enclosed by the dashed line in Figure 3C. The cover 12 has a notch 121, as shown in the light gray area enclosed by the dashed line in Figure 3C. The notches 111 and 121 together form the second entrance 521 of the first pickup channel 500.

[0071] It is understood that Figures 3A to 3C only show a partial distribution scheme of the second entrance 521 of the first pickup channel 500 in the middle frame 11 and the cover 12, and do not constitute a specific limitation on the implementation of this application.

[0072] In some other embodiments of this application, the second entrance 521 of the first pickup channel 500 may also be enclosed by the middle frame 11. That is, the second entrance 521 of the first pickup channel 500 is opened on the middle frame 11.

[0073] In some other embodiments of this application, the second entrance 521 of the first pickup channel 500 may also be enclosed by the cover 12. That is, the second entrance 521 of the first pickup channel 500 is opened on the cover 12.

[0074] After introducing the configuration of the second inlet 521 of the first pickup channel 500, the following section, with reference to the accompanying drawings, introduces an exemplary configuration of the channel segment connecting the second inlet 521 and the outlet 502.

[0075] Referring again to FIG2B, in some embodiments of this application, the first pickup channel 500 includes a first channel segment 500A and a second channel segment 500B. The first channel segment 500A may be, for example, the area filled with dots in FIG2B, and the second channel segment 500B may be, for example, the area filled with grid lines in FIG2B.

[0076] Specifically, the first channel segment 500A and the second channel segment 500B are connected. Furthermore, along the extension direction of the second pickup path 520 of the first pickup channel 500, the first channel segment 500A is closer to the outlet 502 of the first pickup channel 500 than the second channel segment 500B. The entrance of the second channel segment 500B constitutes the second entrance 521. For example, the channel segment formed by the first channel segment 500A and the second channel segment 500B can be a branch of the Y-shaped fork structure of the first pickup channel 500.

[0077] In this design, the extension direction of the first channel segment 500A intersects with the extension direction of the second channel segment 500B. Thus, the projection of the second entrance 521 onto the first channel segment 500A lies within the channel surface of the first channel segment 500A and / or the channel surface of the second channel segment 500B. This means that no straight line outside the foldable phone 1 can pass through the second entrance 521, the second channel segment 500B, or the first channel segment 500A to enter the interior of the foldable phone 1. Therefore, when a user observes the interior of the foldable phone 1 through the second entrance 521, they can only observe the channel surface of the first channel segment 500A and / or the channel surface of the second channel segment 500B from any angle, without observing other internal components, effectively improving the aesthetics and refinement of the foldable phone 1.

[0078] It is understood that the first channel segment 500A and the second channel segment 500B in this application can be extended in various ways. This application does not make specific limitations in this regard. Any first channel segment 500A and second channel segment 500B that can meet the above conditions are within the protection scope of this application.

[0079] In some implementations, the first channel segment 500A and the second channel segment 500B can each extend along a straight line.

[0080] For example, in the example shown in Figure 2B, the extension direction of the first channel segment 500A is the Z-axis direction, and the extension direction of the second channel segment 500B is the Y-axis direction. The channel segment formed by the first channel segment 500A and the second channel segment 500B is similar to an L-shape.

[0081] In some other implementations, the first channel segment 500A and / or the second channel segment 500B may also extend along a certain curve.

[0082] For example, Figure 4 illustrates another exemplary structure of the first channel segment 500A and the second channel segment 500B in an embodiment of this application. Referring to Figure 4, the first channel segment 500A extends along a straight line, and the extension direction of the first channel segment 500A is the Z-axis direction. The second channel segment 500B extends along a curve, and the extension direction of the second channel segment 500B is the M-direction. The channel segment formed by the connection of the first channel segment 500A and the second channel segment 500B is generally similar to a J-shape.

[0083] It is understood that Figures 2B and 4 only show some extensions of the first channel segment 500A and the second channel segment 500B, and do not constitute a specific limitation on the implementation of this application.

[0084] It is understood that this application does not specifically limit the composition of the channel wall of the first channel segment 500A and the channel wall of the second channel segment 500B.

[0085] In some implementations, such as shown in Figure 2B, the channel wall of the first channel segment 500A is a combination of the surface of the middle frame 11 and the surface of the cover 12, and the channel wall of the second channel segment 500B is also a combination of the surface of the middle frame 11 and the surface of the cover 12.

[0086] In some other implementations, such as those shown in Figure 4, the channel wall of the first channel segment 500A is the surface of the middle frame 11, and the channel wall of the second channel segment 500B is a combination of the surface of the middle frame 11 and the surface of the cover 12.

[0087] It is understood that Figures 2B and 4 only show the composition scheme of the channel wall of the first channel segment 500A and the channel wall of the second channel segment 500B, and do not constitute a specific limitation on the implementation of this application.

[0088] In some embodiments of this application, the second entry 521 is rectangular in shape. This allows the second entry 521 to be made as narrow as possible, making it difficult for users to observe its presence, thereby improving the aesthetics and refinement of the foldable phone 1.

[0089] In some implementations, when the second inlet 521 is rectangular, its length is 3mm to 5mm, for example, 3mm, 4mm, 5mm, etc. In this way, the second inlet 521 can be made as small as possible while ensuring the sound pickup effect of the first microphone assembly 50, thereby reducing the impact of the second inlet 521 on the appearance of the foldable phone 1 and improving its aesthetics and refinement.

[0090] In some implementations, when the second inlet 521 is rectangular, its width is 0.1mm to 0.2mm, for example, 0.1mm, 0.15mm, 0.2mm, etc. In this way, the second inlet 521 can be made as small as possible while ensuring the sound pickup effect of the first microphone assembly 50, thereby reducing the impact of the second inlet 521 on the appearance of the foldable phone 1 and improving its aesthetics and refinement.

[0091] In some embodiments of this application, the area of ​​the second inlet 521 can be 0.3 mm². 2 ~1mm 2 For example, 0.3mm 2 0.4mm 2 0.5mm 2 Thus, the second entry point 521 can be set as small as possible while ensuring the sound pickup effect of the first microphone assembly 50, so as to reduce the impact of the second entry point 521 on the appearance of the foldable phone 1 and improve the aesthetics and refinement of the foldable phone 1.

[0092] In some alternative implementations, the shape of the second inlet 521 can also be other shapes, such as at least one of regular shapes like a circle, triangle, or pentagon. In other alternative implementations, the shape of the second inlet 521 can also be an irregular shape, which is not specifically limited in this application.

[0093] In addition, in some implementations, the cross-sectional shape at different locations in the first pickup channel 500 can be the same. In other alternative implementations, the cross-sectional shape at different locations in the first pickup channel 500 can be different. This application does not specifically limit this. It is understood that in this application, a cross-section refers to a plane perpendicular to the extension direction of the component, and the cross-sectional shape refers to the shape obtained after the component is cut along the cross-section.

[0094] In some implementations, the cross-sectional shape of the first pickup channel 500 can be at least one of regular shapes such as rectangle, circle, triangle, and pentagon. In other alternative implementations, the cross-sectional shape of the first pickup channel 500 can also be an irregular shape. This application does not impose specific limitations on this.

[0095] In some embodiments of this application, the first pickup channel 500 can be formed by machining, such as drilling or CNC machining. The forming method is simple, easy to process, and low in cost.

[0096] In some embodiments of this application, the middle frame 11 and the cover 12 can be sealed and bonded together by applying adhesive, thereby achieving the functions of waterproofing and dustproofing, and effectively reducing the possibility of sound leakage.

[0097] In some embodiments of this application, a sealing element 70 (e.g., foam) is provided between the outlet 512 of the first pickup path 510 and the first microphone assembly 50 to provide a seal and prevent sound leakage.

[0098] In some embodiments of this application, the first microphone assembly 50 may include a circuit board 51 and a microphone unit 52. The microphone unit 52 is disposed on the circuit board 51 and electrically connected to the motherboard (not shown) through the circuit board 51. Sound emitted from an external sound source of the foldable phone 1 can be transmitted to the first microphone assembly 50 inside the foldable phone 1 via the first pickup channel 500. Then, the first microphone assembly 50 converts the sound signal into an electrical signal, which is then processed (e.g., amplified, filtered, etc.) by the circuit board 51 and transmitted to the motherboard. The processor on the motherboard can further process, analyze, or store the audio signal from the first microphone assembly 50.

[0099] It should be noted that this embodiment is an exemplary description of the technical solution of this application, and those skilled in the art can make other modifications. For example, in this embodiment, the electronic device is a two-fold folding mobile phone 1 that folds vertically. When the folding mobile phone 1 is in a flattened state, its top 101 and bottom 102 are spaced apart along the X-axis; when the folding mobile phone 1 is in a folded state, the distance between its top 101 and bottom 102 along the X-axis becomes smaller, for example, reduced to 0. However, this application is not limited to this, and in other embodiments, the electronic device can also be a device of other forms.

[0100] For example, in some embodiments, the electronic device can also be a bi-fold phone that folds left and right. The distance between the top and bottom of the phone along the X-axis remains unchanged during the process of switching between the flat and folded states.

[0101] For example, in some other embodiments, the electronic device can also be a tri-fold phone. Here, the tri-fold structure refers to a folding phone comprising three main bodies and two hinge mechanisms, with adjacent main bodies connected by a hinge mechanism. Adjacent main bodies can rotate towards each other by folding inwards or outwards until the included angle between them is approximately 0°, thus placing the folding phone in an inward-folded or outward-folded state. Adjacent main bodies can also rotate away from each other until the included angle between them is approximately 180°, thus placing the folding phone in a flattened state.

[0102] For example, in some other embodiments, the electronic device may also be a candybar phone.

[0103] It is understood that any electronic device that covers the gap between the middle frame 11 and the display screen 40 by means of the cover 12 can be used as the electronic device in this application, and this application does not make any specific limitation. The configuration scheme of the first pickup channel 500 in this application has a wide range of applications and strong adaptability.

[0104] In this embodiment, the technical solution of this application is described based on the fact that the first microphone assembly 50 is located close to the left side 103 of the foldable phone 1, and the first entry point 511 is located on the left side 103 of the foldable phone 1. However, this application is not limited to this, and the first entry point 511 may also be located on other sides of the foldable phone 1.

[0105] For example, in some embodiments, the first microphone assembly 50 may also be positioned close to the top 101 of the foldable phone 1 (as another example of the first side), and the first inlet 511 may be located at the top 101 of the foldable phone 1. When the first inlet 511 is located at the top 101 of the foldable phone 1, along the X-axis direction (as another example of the first direction), the orthographic projection of the second inlet 521 in the XY plane is closer to the first microphone assembly 50 than the orthographic projection of the first inlet 511 in the XY plane. This reduces the probability of the user completely blocking both the first inlet 511 and the second inlet 521 while using the foldable phone 1, effectively reducing the risk of clogging and thus enhancing the sound pickup performance of the first microphone assembly 50.

[0106] In some implementations, to achieve the breath wake-up function of the aforementioned foldable phone 1, in some embodiments of this application, the entrance of the second microphone assembly 60 may be located on the left side portion 103 or the right side portion 104. This application does not limit this, as long as the sound signal picked up by the first microphone assembly 50 and the sound signal picked up by the second microphone assembly 60 have a phase difference in the X-axis direction to achieve the breath wake-up function of the foldable phone 1.

[0107] It is understood that the first entrance 511 and the second entrance 521 located on other sides have essentially the same structure as the first entrance 511 and the second entrance 521 located on the left side 103. Only the orientation of the entrances needs to be changed accordingly, which will not be elaborated here.
