Abstract
Description
Electronic device
[0001] This application claims priority from the Chinese patent application No. 202410565330.9 filed on May 08, 2024, and entitled "Electronic device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD
[0002] The present application relates to the technical field of electronic devices, and in particular to an electronic device. BACKGROUND
[0003] Microphones (MICs) are widely used in electronic devices as important sound pickup devices. The microphone is usually arranged inside the electronic device. In order to realize the sound pickup function of the microphone, a sound pickup channel is usually formed on the electronic device. The sound pickup channel is arranged at a position matched with the arrangement position of the microphone. The sound outside the electronic device can enter the inside of the electronic device through the sound pickup channel and be introduced into the microphone.
[0004] However, the current sound pickup channel usually has only one entrance. When the entrance of the sound pickup channel is arranged on the side of the electronic device, the user is likely to block the entrance of the sound pickup channel during use of the electronic device, resulting in abnormal sound pickup function of the microphone. SUMMARY
[0005] To solve the above problems, the present application provides an electronic device. By increasing the number of entrances of the sound pickup channel to two and adjusting the relative positions of the two entrances, it is difficult for the user to completely block the two entrances of the sound pickup channel at the same time when using the electronic device, thereby effectively reducing the risk of blocking the hole and improving the sound pickup performance of the microphone assembly.
[0006] In a first aspect, the present application provides an electronic device, which comprises a first shell, a second shell, a first microphone assembly, and a display screen. The display screen and the first microphone assembly are supported on the first shell. The second shell surrounds the four sides of the display screen and is connected to the first shell. At least part of the second shell is located on the side of the display screen opposite to the first shell and covers the edge of the display screen.
[0007] The electronic device is also provided with a first sound pickup channel. The first sound pickup channel comprises a first entrance and a second entrance. The first entrance and the second entrance are respectively connected to the outside of the electronic device. The first entrance is arranged on a first side of the four side parts of the electronic device and surrounded by the first shell. The second entrance is surrounded by the first shell and / or the second shell. The outlet of the first sound pickup channel is connected to the first microphone assembly.
[0008] In the first direction, the second entrance is closer to the first microphone assembly than the first entrance in the orthographic projection of the first plane, the first plane being a plane in which a length direction of the electronic device and a width direction of the electronic device are located, and the first direction being a direction from the first side to another side disposed opposite to the first side.
[0009] In the electronic device, since the first entrance and the second entrance are staggered, the probability that the user completely blocks the first entrance and the second entrance at the same time when using the electronic device is small, the risk of blocking the hole is effectively reduced, and the sound pickup performance of the first microphone assembly is enhanced.
[0010] In a possible implementation of the first aspect, in the thickness direction of the electronic device, the second entrance is closer to the display screen than the first entrance. Thus, the risk of blocking the hole of the second entrance is further reduced, and the sound pickup performance of the first microphone assembly is further improved.
[0011] In a possible implementation of the first aspect, the second entrance is disposed on the first side.
[0012] In a possible implementation of the first aspect, the area of the orthographic projection of the second entrance on the first plane is 0. Thus, when the user observes the electronic device from the side where the display screen is located, the second entrance cannot be observed at all. Therefore, other components inside the electronic device cannot be observed through the second entrance, and the appearance and delicacy of the electronic device are effectively improved.
[0013] In a possible implementation of the first aspect, in the thickness direction of the electronic device, a notch is formed on the surface of the second housing facing the first housing, and the notch and the first housing jointly enclose the second entrance.
[0014] It can be understood that, in the thickness direction of the electronic device, the surface of the second housing facing the first housing is an inner surface of the second housing. When the user observes the electronic device from the side where the display screen is located, the appearance surface of the second housing can be observed, but the inner surface of the second housing cannot be observed, and thus the notch formed on the inner surface of the second housing cannot be observed. The appearance and delicacy of the electronic device can be effectively improved.
[0015] In addition, by forming the notch on the second housing, and jointly forming the second entrance of the first sound pickup channel by the notch and the first housing, the second entrance with a smaller size can be easily formed, which is conducive to setting the second entrance in a micro gap structure, thereby further reducing the influence of the second entrance on the appearance of the electronic device, and improving the appearance and delicacy of the electronic device.
[0016] In a possible implementation of the first aspect, the first sound pickup channel section includes a first channel section and a second channel section, an inlet of the second channel section constitutes the second inlet, an outlet of the second channel section is in communication with the first channel section, and an extension direction of the first channel section intersects an extension direction of the second channel section.
[0017] That is, any straight line outside the electronic device cannot pass through the second inlet, the second channel section, and the first channel section to enter the interior of the electronic device. In this way, when a user looks into the interior of the electronic device through the second inlet, the user can only observe the channel surface of the first channel section and / or the channel surface of the second channel section at any angle, and cannot observe other component structures in the interior of the electronic device, effectively improving the appearance and delicacy of the electronic device.
[0018] In a possible implementation of the first aspect, the second inlet is rectangular in shape. In this way, the second inlet can be made as narrow as possible, so that the user is less likely to observe the existence of the second inlet, and the appearance and delicacy of the electronic device are better.
[0019] In a possible implementation of the first aspect, the second inlet has a length of 3 mm to 5 mm, for example, 3 mm, 4 mm, or 5 mm. In this way, the second inlet can be made as small as possible while ensuring the sound pickup effect of the first microphone assembly, so as to reduce the influence of the second inlet on the appearance of the electronic device and improve the appearance and delicacy of the electronic device.
[0020] In a possible implementation of the first aspect, the second inlet has a width of 0.1 mm to 0.2 mm, for example, 0.1 mm, 0.15 mm, or 0.2 mm. In this way, the second inlet can be made as small as possible while ensuring the sound pickup effect of the first microphone assembly, so as to reduce the influence of the second inlet on the appearance of the electronic device and improve the appearance and delicacy of the electronic device.
[0021] In a possible implementation of the first aspect, the first side is a left side or a right side of the electronic device in a width direction of the electronic device.
[0022] In a possible implementation of the first aspect, the electronic device includes a second microphone assembly and a second sound pickup channel. An inlet of the second sound pickup channel is arranged on a second side of the four circumferential sides of the electronic device, the second side is adjacent to the first side, an outlet of the second sound pickup channel is connected to the second microphone assembly, and the second microphone assembly is supported on the first shell.
[0023] Based on this, the breath wake-up function of the electronic device can be implemented through cooperation of the first microphone assembly and the second microphone assembly, and the risk of plugging is small, and the sound pickup performance of the first microphone assembly is good.
[0024] In a possible implementation of the first aspect, the first side is a left side or a right side of the electronic device in a width direction of the electronic device, and the second side is a top side or a bottom side of the electronic device in a length direction of the electronic device.
[0025] In a possible implementation of the first aspect, the electronic device includes a first body and a second body, and the first body and the second body are capable of relative rotation to enable the electronic device to be folded or unfolded. The housing of one of the first body and the second body includes a first housing and a second housing.
[0026] Based on this, the breath wake-up function of the electronic device can be implemented through cooperation of the first microphone assembly and the second microphone assembly, and the risk of plugging is small, and the sound pickup performance of the first microphone assembly is good.

[0036] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0037] The electronic device can include, but is not limited to, a mobile phone (for example, a folding mobile phone, a straight mobile phone), a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a netbook, a personal digital assistant (PDA), a wearable device, a virtual reality device, and the like, and an electronic device with a microphone. For the convenience of description, the electronic device is taken as a folding mobile phone in the following description. In addition, for the convenience of description, a state of the folding mobile phone after being folded is defined as a folded state, a state of the folding mobile phone after being unfolded is defined as an unfolded state, and a state of the folding mobile phone between the folded state and the unfolded state is defined as an intermediate state (or a hovering state).
[0038] FIGS. 1A to 1C show structural schematic diagrams of a folding mobile phone 1a in an embodiment of the present application. FIG. 1A shows the unfolded state of the folding mobile phone 1a, FIG. 1B shows a cross-sectional view of part of the structure of the folding mobile phone 1a along the A-A section in FIG. 1A, and FIG. 1C shows the folded state of the folding mobile phone 1a.
[0039] For the convenience of description, the X-axis direction, the Y-axis direction, and the Z-axis direction of the folding mobile phone 1a are defined in combination with FIG. 1A before the specific structure of the folding mobile phone 1a is introduced. As shown in FIG. 1A, the X-axis direction is the length direction of the folding mobile phone 1a in the unfolded state, for example, the direction from the top 101 to the bottom 102 of the folding mobile phone 1a in the unfolded state is the positive direction of the X-axis; the Y-axis direction is the width direction of the folding mobile phone 1a in the unfolded state, for example, the direction from the left side 103 to the right side 104 of the folding mobile phone 1a in the unfolded state is the positive direction of the Y-axis; and the Z-axis direction is the thickness direction of the folding mobile phone 1a in the unfolded state, for example, the direction from the back to the front of the folding mobile phone 1a in the unfolded state is the positive direction of the Z-axis. In some embodiments of the present application, the X-axis direction, the Y-axis direction, and the Z-axis direction are mutually intersected. In some implementation manners, the X-axis direction, the Y-axis direction, and the Z-axis direction can be mutually perpendicular.
[0040] It can be understood that the mutual perpendicularity in the present application is not absolute perpendicularity, and approximate perpendicularity (for example, the included angle between two structural features is 92°, 89.9°, 89°, 88°, etc.) caused by factors such as processing errors and assembly errors is also within the range of mutual perpendicularity in the present application. The definition of mutual perpendicularity will not be repeatedly described hereinafter. The mutual parallelism in the present application is also not absolute parallelism, and approximate parallelism (for example, the included angle between two structural features is 181°, 179.8°, 179°, 178°, etc.) caused by factors such as processing errors and assembly errors is also within the range of mutual parallelism in the present application. The definition of mutual parallelism will not be repeatedly described hereinafter.
[0041] Referring to FIGS. 1A-1C, the folding mobile 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 arranged on opposite sides of the hinge 30 and are respectively connected with the hinge 30 to achieve rotational connection of the first body 10 and the second body 20. 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 be relatively rotated through the hinge 30 and can drive the display screen 40 to fold or flatten, so that the folding mobile phone 1a can be switched between a flattened state shown in FIG. 1A and a folded state shown in FIG. 1C.
[0042] The first body 10 of the folding mobile phone 1a is internally provided with a first microphone assembly 50 and a second microphone assembly 60 to achieve a folding state breath awakening function of the folding mobile phone 1a.
[0043] Specifically, the first microphone assembly 50 is arranged close to a left side 103 of the folding mobile phone 1a. In order to achieve the sound pickup function of the first microphone assembly 50, the folding mobile phone 1a is further provided with a first sound pickup channel 500a. Referring to FIG. 1B in combination with FIG. 1A, in some embodiments, the first body 10 includes a middle frame 11a. The first sound pickup channel 500a is surrounded by the middle frame 11a, for example, the extension track of the first sound pickup channel 500a is shown by a dotted line in FIG. 1B. The first sound pickup channel 500a is connected with the outside of the folding mobile phone 1a and the first microphone assembly 50. The inlet 501a of the first sound pickup channel 500a is arranged on the left side 103 of the folding mobile phone 1a and is connected with the outside of the folding mobile phone 1a. The outlet 502a of the first sound pickup channel 500a is arranged inside the folding mobile phone 1a and is connected with the first microphone assembly 50 inside the folding mobile phone 1a. In this way, the first microphone assembly 50 can pick up the sound outside the folding mobile phone 1a through the first sound pickup channel 500a.
[0044] It can be understood that the inlet of the sound pickup channel refers to the port on the side of the sound pickup channel away from the microphone assembly, and the outlet of the sound pickup channel refers to the port on the side of the sound pickup channel close to the microphone assembly, for example, a sound pickup channel includes a first port and a second port, the first port is connected with the outside, and the second port is connected with the microphone assembly, then the first port is the inlet and the second port is the outlet. The concept of the inlet of the sound pickup channel and the outlet of the sound pickup channel will not be repeated in the following. It can also be understood that the left side 103 of the folding mobile phone 1a includes at least part of the structure of the first middle frame 11a.
[0045] The second microphone assembly 60 is arranged close to the top 101 of the folding mobile phone 1a. Correspondingly, the folding mobile phone 1a is provided with a second sound pickup channel 600, an entrance (not labeled) of the second sound pickup channel 600 being arranged on the top 101 of the folding mobile phone 1a to be connected to the outside of the folding mobile phone 1a. An exit (not labeled) of the second sound pickup channel 600 is connected to the second microphone assembly 60 inside the folding mobile phone 1a. In this way, the second microphone assembly 60 can pick up the sound outside the folding mobile phone 1a through the second sound pickup channel 600.
[0046] As can be seen from FIGS. 1A and 1C, the sound pickup paths of the first microphone assembly 50 and the second microphone assembly 60 have a position difference in the X-axis direction, regardless of whether the folding mobile phone 1a is in the unfolded state or the folded state. Therefore, the sound signals picked up by the first microphone assembly 50 and the second microphone assembly 60 have a phase difference in the X-axis direction. In this way, the folding mobile phone 1a in the folded state can extract a first breath feature generated when a user speaks close to the folding mobile phone 1a based on the sound signal picked up by the first microphone assembly 50, and extract a second breath feature generated when the user speaks close to the folding mobile phone 1a based on the sound signal picked up by the second microphone assembly 60, and finally realize breath wake-up based on the first breath feature and the second breath feature. For example, when the user speaks a voice interaction instruction close to the folding mobile phone 1a, the folding mobile phone 1a can extract the first breath feature and the second breath feature of the user, and then enter a breath wake-up mode to operate according to the voice interaction instruction. For example, the user can speak “What is the weather like today?” to wake up the voice assistant to obtain weather information without performing additional actions, such as using a dedicated wake-up word to wake up the voice assistant, long-pressing the power to wake up the voice assistant, and the like, thereby effectively improving the continuity of human-computer interaction.
[0047] It is worth noting that since the entrance 501a of the first sound pickup channel 500a is arranged on the left side 103 of the folding mobile phone 1a, and the user usually holds the folding mobile phone 1a with the left hand when using the folding mobile phone 1a, it is extremely easy to block the entrance 501a of the first sound pickup channel 500a, which causes the sound pickup function of the first microphone assembly 50 to be abnormal, and further affects the breath wake-up function of the folding mobile phone 1a. For example, the plugging risk is more than 50%, the plugging wake-up success rate when holding the folding mobile phone 1a with the left hand is only 70%, and the plugging wake-up success rate when holding the folding mobile phone 1a with the right hand is only 45%, the plugging risk is high, and the breath wake-up success rate is low.
[0048] To solve the above problems, the application provides a folding mobile phone. The first sound pickup channel of the folding mobile phone includes two entrances. By adjusting the relative positions of the two entrances, it is difficult for a user to completely block the two entrances of the first sound pickup channel when using the folding mobile phone, thereby effectively reducing the risk of blocking holes, improving the sound pickup performance of the first microphone assembly, and further improving the breath wake-up success rate of the folding mobile phone. The technical solutions of the application are described below with reference to the drawings.
[0049] FIGS. 2A and 2B show structural schematic diagrams of the folding mobile phone 1 in the application. FIG. 2A shows the unfolded state of the folding mobile phone 1, and FIG. 2B shows a cross-sectional view of part of the structure of the folding mobile phone 1 in the B-B section of FIG. 2A.
[0050] Referring to FIGS. 2A and 2B, the folding mobile phone 1 includes a middle frame 11 (as an example of a first housing), a cover 12 (also referred to as a “small A shell”, as an example of a second housing), a display screen 40, and a first microphone assembly 50.
[0051] The middle frame 11 is used to support the display screen 40 and the first microphone assembly 50. In some embodiments of the application, based on the appearance of the whole machine and the folding requirement, the display screen 40 cannot be directly bonded with the middle frame 11 by point gluing, and a gap is formed between the display screen 40 and the middle frame 11. In the application, the gap formed between the display screen 40 and the middle frame 11 refers to the gap observed between the periphery of the display screen 40 and the periphery of the middle frame 11 when a user observes the folding mobile phone 1 from the side of the display screen 40 along the Z-axis direction, for example, the gap Gap shown in FIG. 2B. As shown in FIGS. 2A and 2B, the cover 12 is arranged around the edge of the display screen 40 and connected with the middle frame 11. Moreover, at least part of the cover 12 is located on the side of the display screen 40 away from the middle frame 11 and covers the edge of the display screen 40. In this way, the cover 12 can cover the gap Gap between the display screen 40 and the middle frame 11, so that the appearance of the folding mobile phone 1 is more beautiful, and the installation requirement of the display screen 40 is met at the same time.
[0052] The folding mobile phone 1 is also provided with a first sound pickup channel 500. The first sound pickup channel 500 is connected between the first microphone assembly 50 and the outside of the folding mobile phone 1, and is used to realize the sound pickup function of the first microphone assembly 50.
[0053] Specifically, the first sound pickup channel 500 is a Y-shaped fork structure as a whole, including two entrances and an exit.
[0054] The two inlets of the first sound pickup channel 500 are a first inlet 511 and a second inlet 521. The first inlet 511 and the second inlet 521 are respectively arranged on the outer surface of the folding mobile phone 1 and connected to the outside of the folding mobile phone 1. That is, a user can observe and touch the first inlet 511 and the second inlet 521 from the outside of the folding mobile phone 1.
[0055] The first inlet 511 is arranged on a first side of the four sides of the folding mobile phone 1. The four sides of the folding mobile phone 1 refer to a top (for example, the top 101), a bottom (for example, the bottom 102), a left side (for example, the left side 103), and a right side (for example, the right side 104) of the folding mobile phone 1 when a user observes the folding mobile phone 1 from the side where the display screen 40 is located. Hereinafter, the left side 103 is taken as an example of the first side to continue to introduce the embodiments of the present application.
[0056] The first inlet 511 is arranged on the left side 103. It can also be understood that the area of the orthographic projection of the first inlet 511 on the XZ plane is greater than 0. The first inlet 511 is surrounded by the middle frame 11. It can be understood that the left side 103 of the folding mobile phone 1 includes at least part of the middle frame 11, which surrounds the first inlet 511.
[0057] The second inlet 521 is surrounded by the middle frame 11 and / or the cover 12. For example, in FIGS. 2A and 2B, the second inlet 521 is surrounded by the middle frame 11 and the cover 12 as an example. In the Y-axis direction (as an example of the first direction), the orthographic projection of the second inlet 521 on 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 on the XY plane. That is, the first inlet 511 and the second inlet 521 are arranged staggered in the Y-axis direction.
[0058] The outlet 502 of the first sound pickup channel 500 is arranged in the inside of the folding mobile phone 1 and connected to the first microphone assembly 50 inside the folding mobile phone 1.
[0059] Based on this, the first microphone assembly 50 can have two sound pickup paths, which are 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 dash-dot line in FIG. 2B. Along the first sound pickup path 510, the sound outside the folding mobile phone 1 can be transmitted to the outlet 502 through the first inlet 511 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-dot-dash line in FIG. 2B. Along the second sound pickup path 520, the sound outside the folding mobile phone 1 can be transmitted to the outlet 502 through the second inlet 521 and finally picked up by the first microphone assembly 50.
[0060] In the folding mobile phone 1, the first inlet 511 and the second inlet 521 are staggered along the Y-axis direction, so that the probability of the user completely blocking the first inlet 511 and the second inlet 521 at the same time when using the folding mobile phone 1 is small, the risk of blocking the hole is effectively reduced, the sound pickup performance of the first microphone assembly 50 is enhanced, and the success rate of breath wake-up of the folding mobile phone 1 is effectively improved. For example, compared with the scheme shown in FIGS. 1A-1C, the success rate of breath wake-up of the folding mobile phone 1 provided by the present application can be improved from 70% for left-hand holding and 45% for right-hand holding to 90% for both left-hand and right-hand holding, and the user experience is good.
[0061] Referring back to FIG. 2B, in some embodiments of the present application, the second inlet 521 is closer to the display screen 40 than the first inlet 511 along the Z-axis direction. Generally, when a user uses the folding mobile phone 1, the display screen 40 of the folding mobile phone 1 faces the user, and the back of the folding mobile phone 1 faces away from the user. The palm of the user's hand covers the back of the folding mobile phone 1, and the fingers extend from the back of the folding mobile phone 1 to the front of the folding mobile phone 1, i.e., the side where the display screen 40 is located. It can be understood that, according to the common holding habit of users, the closer the side of the folding mobile phone 1 to the display screen 40 along the Z-axis direction, the smaller the probability of being covered by the fingers. Therefore, by arranging the second inlet 521 close to the display screen 40, the risk of blocking the hole of the second inlet 521 can be further reduced, and the sound pickup performance of the first microphone assembly 50 can be improved.
[0062] Referring back to FIG. 2B, in some embodiments of the present application, the second inlet 521 can be arranged on the same side of the folding mobile phone 1 as the first inlet 511. For example, in the present embodiment, the second inlet 521 and the first inlet 511 are arranged on the left side 103 of the folding mobile phone 1. It can also be understood that the area of the orthogonal projection of the second inlet 521 on the XZ plane is greater than 0.
[0063] Further, in some embodiments of the present application, the area of the orthogonal projection of the second inlet 521 on the XY plane is 0. In this way, when a user observes the folding mobile phone 1 from the side where the display screen 40 is located (e.g., along the negative direction of the Z-axis), the second inlet 521 cannot be observed at all. Therefore, other components inside the folding mobile phone 1 cannot be observed through the second inlet 521, and the appearance and delicacy of the folding mobile phone 1 are effectively improved.
[0064] It can be understood that the distribution of the second inlet 521 of the first sound pickup channel 500 on the middle frame 11 and the cover 12 can be various.
[0065] In some embodiments of the present application, the second entrance 521 of the first sound pickup channel 500 is formed by the middle frame 11 and the cover 12. In other words, the second entrance 521 of the first sound pickup channel 500 is formed on the middle frame 11 and the cover 12. Details will be described below in combination with the drawings.
[0066] FIGS. 3A-3C show side views of some structures in the folding mobile phone 1 in some embodiments of the present application. Referring to FIG. 3A, in some implementations, a notch 121 is formed on the first surface 12A of the cover 12, for example, as shown by the light gray area enclosed by the dashed line in FIG. 3A. The notch 121 and the surface of the middle frame 11 facing the notch 111 together form the second entrance 521 of the first sound pickup channel 500. Here, the first surface 12A of the cover 12 is the surface of the cover 12 opposite the middle frame 11 along the Z-axis direction. In other words, the first surface 12A of the cover 12 is the inner surface of the cover 12, i.e., the first surface 12A of the cover 12 cannot be directly observed from the outside of the folding mobile phone 1.
[0067] It can be understood that when a user observes the folding mobile phone 1 from the side where the display screen 40 is located (e.g., along the negative direction of the Z-axis), the second surface 12B of the cover 12, i.e., the appearance surface of the cover 12, can be observed, while the first surface 12A of the cover 12 cannot be observed, and thus the notch 121 formed on the first surface 12A of the cover 12 cannot be observed, which can effectively improve the appearance and delicacy of the folding mobile phone 1.
[0068] In addition, by forming the notch 121 on the cover 12 and then forming the second entrance 521 of the first sound pickup channel 500 by the notch 121 and the middle frame 11 together, the size of the second entrance 521 along the Z-axis direction can be smaller, which is conducive to setting the second entrance 521 in the form of a small gap, thereby further reducing the influence of the second entrance 521 on the appearance of the folding mobile phone 1 and improving the appearance and delicacy of the folding mobile phone 1.
[0069] Referring to FIG. 3B, in alternative other implementations, a notch 111 is formed on the middle frame 11, for example, as shown by the dark gray area enclosed by the dashed line in FIG. 3B. The notch 111 and the surface of the cover 12 facing the notch 111 together form the second entrance 521 of the first sound pickup channel 500.
[0070] Referring to FIG. 3C, in alternative other implementations, a notch 111 is formed on the middle frame 11, for example, as shown by the dark gray area enclosed by the dashed line in FIG. 3C. A notch 121 is formed on the cover 12, for example, as shown by the light gray area enclosed by the dashed line in FIG. 3C. The notch 111 and the notch 121 together form the second entrance 521 of the first sound pickup channel 500.
[0071] It can be understood that FIGS. 3A-3C only show a partial distribution scheme of the second entrance 521 of the first sound pickup channel 500 on the middle frame 11 and the cover 12, and do not constitute a specific limitation on the implementation manners of the present application.
[0072] In some other embodiments of the present application, the second entrance 521 of the first sound pickup channel 500 can also be surrounded by the middle frame 11. That is, the second entrance 521 of the first sound pickup channel 500 is formed on the middle frame 11.
[0073] In some other embodiments of the present application, the second entrance 521 of the first sound pickup channel 500 can also be surrounded by the cover 12. That is, the second entrance 521 of the first sound pickup channel 500 is formed on the cover 12.
[0074] After introducing the setting manners of the second entrance 521 of the first sound pickup channel 500, the exemplary setting manners of the channel segment connected between the second entrance 521 and the outlet 502 will be introduced below in combination with the accompanying drawings.
[0075] With reference to FIG. 2B, in some embodiments of the present application, the first sound pickup channel 500 includes a first channel segment 500A and a second channel segment 500B. The first channel segment 500A can be, for example, the area filled with dots in FIG. 2B, and the second channel segment 500B can be, for example, the area filled with grid lines in FIG. 2B.
[0076] Specifically, the first channel segment 500A and the second channel segment 500B are connected in communication. And, along the extension direction of the second sound pickup path 520 of the first sound pickup channel 500, the first channel segment 500A is closer to the outlet 502 of the first sound pickup channel 500 than the second channel segment 500B. The entrance of the second channel segment 500B constitutes the second entrance 521. Exemplarily, the channel segment connected by the first channel segment 500A and the second channel segment 500B can be one branch of the first sound pickup channel 500 in a Y-shaped fork structure.
[0077] The extension direction of the first channel segment 500A intersects with the extension direction of the second channel segment 500B. In this way, the projection of the second entrance 521 to the first channel segment 500A is located in the channel surface of the first channel segment 500A and / or the channel surface of the second channel segment 500B. That is, any straight line outside the folding mobile phone 1 cannot pass through the second entrance 521, the second channel segment 500B, and the first channel segment 500A to enter the inside of the folding mobile phone 1. In this way, when a user looks into the inside of the folding mobile phone 1 through the second entrance 521, any angle can only observe the channel surface of the first channel segment 500A and / or the channel surface of the second channel segment 500B, and cannot observe other component structures inside the folding mobile phone 1, effectively improving the appearance and delicacy of the folding mobile phone 1.
[0078] It can be understood that the first channel segment 500A and the second channel segment 500B in the present application can extend in various ways, and the present application does not make specific limitation thereon, and any first channel segment 500A and second channel segment 500B that can meet the above conditions are within the protection scope of the present application.
[0079] In some implementations, the first channel segment 500A and the second channel segment 500B can extend along a straight line, respectively.
[0080] For example, in the example shown in FIG. 2B, the first channel segment 500A extends in the Z-axis direction, and the second channel segment 500B extends in the Y-axis direction, and the channel segment formed by the first channel segment 500A and the second channel segment 500B is similar to an L shape as a whole.
[0081] In some other implementations, the first channel segment 500A and / or the second channel segment 500B can also extend along a curve.
[0082] For example, FIG. 4 shows another exemplary structure of the first channel segment 500A and the second channel segment 500B in the embodiments of the present application. Referring to FIG. 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 first channel segment 500A and the second channel segment 500B is similar to a J shape as a whole.
[0083] It can be understood that FIG. 2B and FIG. 4 only show the extension schemes of some first channel segments 500A and second channel segments 500B, and do not constitute specific limitation on the implementations of the present application.
[0084] It can be understood that the present application does not make specific limitation on the composition of the channel wall surface of the first channel segment 500A and the channel wall surface of the second channel segment 500B.
[0085] In some implementations, for example, as shown in FIG. 2B, the channel wall surface of the first channel segment 500A is the combination of the surface of the middle frame 11 and the surface of the cover 12, and the channel wall surface of the second channel segment 500B is also the combination of the surface of the middle frame 11 and the surface of the cover 12.
[0086] In some other implementations, for example, as shown in FIG. 4, the channel wall surface of the first channel segment 500A is the surface of the middle frame 11, and the channel wall surface of the second channel segment 500B is the combination of the surface of the middle frame 11 and the surface of the cover 12.
[0087] It can be understood that FIG. 2B and FIG. 4 only show the composition of the channel wall surface of the partial first channel segment 500A and the channel wall surface of the second channel segment 500B, and do not constitute a specific limitation on the implementation manners of the present application.
[0088] In some embodiments of the present application, the second inlet 521 is rectangular in shape. In this way, the second inlet 521 can be made as narrow as possible to make it difficult for a user to observe the existence of the second inlet 521, thereby making the appearance and delicacy of the folding mobile phone 1 better.
[0089] In some implementation manners, when the second inlet 521 is rectangular in shape, the length of the second inlet 521 is 3mm-5mm, for example, 3mm, 4mm, 5mm, etc. In this way, the second inlet 521 can be made as small as possible while ensuring the pickup effect of the first microphone assembly 50, so as to reduce the influence of the second inlet 521 on the appearance of the folding mobile phone 1 and improve the appearance and delicacy of the folding mobile phone 1.
[0090] In some implementation manners, when the second inlet 521 is rectangular in shape, the width of the second inlet 521 is 0.1mm-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 pickup effect of the first microphone assembly 50, so as to reduce the influence of the second inlet 521 on the appearance of the folding mobile phone 1 and improve the appearance and delicacy of the folding mobile phone 1.
[0091] In some embodiments of the present application, the area of the second inlet 521 can be 0.3mm 2 -1mm 2 , for example, 0.3mm 2 , 0.4mm 2 , 0.5mm 2 , etc. In this way, the second inlet 521 can be made as small as possible while ensuring the pickup effect of the first microphone assembly 50, so as to reduce the influence of the second inlet 521 on the appearance of the folding mobile phone 1 and improve the appearance and delicacy of the folding mobile phone 1.
[0092] In alternative other implementation manners, the shape of the second inlet 521 can also be other shapes, for example, at least one of regular shapes such as a circle, a triangle, a pentagon, etc. In alternative other implementation manners, the shape of the second inlet 521 can also be irregular, which is not limited in the present application.
[0093] In addition, in some implementations, the cross-sectional shape at different positions in the first sound pickup channel 500 can be the same. In alternative implementations, the cross-sectional shape at different positions in the first sound pickup channel 500 can be different. The present application does not limit the cross-sectional shape. It should be understood that, in the present application, the cross-section refers to a plane perpendicular to the extension direction of the component, and the cross-sectional shape refers to the shape of the component after being cut along the cross-section.
[0094] In some implementations, the cross-sectional shape of the first sound pickup channel 500 can be at least one of a regular shape such as a rectangle, a circle, a triangle, a pentagon, etc. In alternative implementations, the cross-sectional shape of the first sound pickup channel 500 can also be an irregular shape. The present application does not limit the cross-sectional shape.
[0095] In some embodiments of the present application, the first sound pickup channel 500 can be formed by machining, such as drilling, computer numerical control (CNC) machining, etc. The forming method is simple, easy to process, and low in cost.
[0096] In some embodiments of the present application, the middle frame 11 and the cover 12 can be sealed and bonded by point bonding, thereby playing a role in waterproofing and dustproofing, and effectively reducing the possibility of sound leakage.
[0097] In some embodiments of the present application, a sealing member 70 (for example, foam) is further arranged between the outlet 512 of the first sound pickup path 510 and the first microphone assembly 50, to play a sealing role and prevent sound leakage.
[0098] In some embodiments of the present application, the first microphone assembly 50 can include a circuit board 51 and a microphone unit 52. The microphone unit 52 is arranged on the circuit board 51 and electrically connected to a main board (not shown) through the circuit board 51. The sound emitted by the sound source outside the folding mobile phone 1 can be transmitted to the first microphone assembly 50 inside the folding mobile phone 1 through the first sound pickup channel 500. Then, the first microphone assembly 50 converts the sound signal into an electrical signal, which is then processed (for example, amplified, filtered, etc.) through the circuit board 51 and transmitted to the main board. The processor on the main board can further process, analyze, or store the audio signal from the first microphone assembly 50.
[0099] It should be noted that the embodiment is an exemplary description of the technical scheme of the present application, and other modifications can be made by those skilled in the art. For example, in the embodiment, the electronic device is a two-fold folding mobile phone 1 which is folded up and down. When the folding mobile phone 1 is in the unfolded state, the top 101 and the bottom 102 are arranged apart along the X-axis direction; when the folding mobile phone 1 is in the folded state, the distance between the top 101 and the bottom 102 along the X-axis direction becomes smaller, for example, to 0. However, the present application is not limited thereto, and in other embodiments, the electronic device can also be other forms of devices.
[0100] For example, in some embodiments, the electronic device can also be a two-fold folding mobile phone which is folded left and right. During arbitrary switching between the unfolded state and the folded state of the folding mobile phone, the distance between the top and the bottom thereof along the X-axis direction does not change.
[0101] For another example, in some other embodiments, the electronic device can also be a three-fold folding mobile phone. The three-fold structure refers to that the folding mobile phone comprises three main bodies and two pivot mechanisms, and the adjacent two main bodies are connected by a pivot mechanism. The adjacent two main bodies can be rotated towards each other by inner folding or outer folding, until the included angle between the adjacent two main bodies is substantially 0°, so that the folding mobile phone is in the inner folded state or the outer folded state. The adjacent two main bodies can also be rotated away from each other, until the included angle between the adjacent two main bodies is substantially 180°, so that the folding mobile phone is in the unfolded state.
[0102] For another example, in some other embodiments, the electronic device can also be a straight mobile phone.
[0103] It can be understood that any electronic device which covers the gap between the middle frame 11 and the display screen 40 by the cover 12 can be used as the electronic device in the present application, and the present application does not make specific limitations thereon. The setting scheme of the first pickup channel 500 in the present application has wide application range and strong adaptability.
[0104] In the embodiment, the first microphone assembly 50 is arranged close to the left side 103 of the folding mobile phone 1, and the first inlet 511 is arranged on the left side 103 of the folding mobile phone 1 to introduce the technical scheme of the present application. However, the present application is not limited thereto, and the first inlet 511 can also be arranged on other sides of the folding mobile phone 1.
[0105] For example, in some embodiments, the first microphone assembly 50 can also be arranged close to the top 101 (as another example of the first side) of the folding mobile phone 1, and the first inlet 511 can be arranged at the top 101 of the folding mobile phone 1. When the first inlet 511 is arranged at the top 101 of the folding mobile phone 1, the normal projection of the second inlet 521 on the XY plane is closer to the first microphone assembly 50 than the normal projection of the first inlet 511 on the XY plane in the X-axis direction (as another example of the first direction). In this way, the probability that a user completely blocks the first inlet 511 and the second inlet 521 at the same time when using the folding mobile phone 1 can be reduced, effectively reducing the risk of blocking, thereby enhancing the sound pickup performance of the first microphone assembly 50.
[0106] In some implementations, in order to achieve the breath wake-up function of the folding mobile phone 1 described above, in some embodiments of the present application, the inlet of the second microphone assembly 60 can be arranged at the left side 103 or the right side 104. The present application does not limit this, as long as the sound signals picked up by the first microphone assembly 50 and the sound signals 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 folding mobile phone 1.
[0107] It can be understood that the first inlet 511 and the second inlet 521 arranged at other sides have substantially the same structure as the first inlet 511 and the second inlet 521 arranged at the left side 103, and only need to be changed in the arrangement direction, which will not be described one by one here.
