[0001] The present application claims priority from the Chinese patent application No. 202411274364.9 filed on September 10, 2024, and entitled "Electronic device and recording method", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of terminal, and in particular to an electronic device and a recording method. BACKGROUND

[0003] At present, electroacoustic devices such as microphones are widely used in electronic devices to support the sound pickup function of the electronic devices. With the development of electronic device technology, people have higher and higher requirements for the sound pickup and other aspects of electronic devices. However, the current arrangement of electroacoustic devices in electronic devices has poor sound pickup effect and cannot meet the user's use requirements, and still needs to be improved. SUMMARY

[0004] The present application provides an electronic device and a recording method, which can at least improve the sound pickup effect of the electronic device to some extent when the first electroacoustic device is a microphone, and can at least improve the sound production effect of the electronic device to some extent when the first electroacoustic device is a loudspeaker, thereby meeting the user's use requirements.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides an electronic device, comprising: a shell and a first electroacoustic device. The shell has a first sound transmission hole, the first sound transmission hole has a first opening area and a second opening area, the first opening area and the second opening area are oriented in different directions; the first electroacoustic device is installed in the shell; a first sound guide is installed in the shell, the first sound guide has a first sound guide opening and a second sound guide opening, the first sound guide opening communicates with the sound hole of the first electroacoustic device, when the electronic device is in a first state, the second sound guide opening is opposite to the first opening area, when the electronic device is in a second state, the second sound guide opening is opposite to the second opening area.

[0007] According to the electronic device provided in the embodiments of the present application, when the electronic device is in the first state, the second sound guide port is opposite to the first opening area, and at this time, the second sound guide port is in communication with the first opening area; when the electronic device is in the second state, the second sound guide port is opposite to the second opening area, and at this time, the second sound guide port is in communication with the second opening area. Therefore, when the second sound guide port is in communication with the first opening area, the sound wave can be transmitted between the first opening area and the sound hole under the communication of the first sound guide piece; when the second sound guide port is in communication with the second opening area, the sound wave can be transmitted between the second opening area and the sound hole under the communication of the first sound guide piece. When the first electro-acoustic device is a microphone, the sound wave is picked up by the first electro-acoustic device, and since the first opening area and the second opening area are different in orientation, this facilitates adjusting the sound pickup direction of the first electro-acoustic device to at least some extent, thereby facilitating improving the sound pickup effect of the first electro-acoustic device to at least some extent. When the first electro-acoustic device is a loudspeaker, the sound wave can be emitted from different opening areas, and since the first opening area and the second opening area are different in orientation, this facilitates adjusting the sound emission direction of the first electro-acoustic device to at least some extent, thereby facilitating improving the sound emission effect of the first electro-acoustic device to at least some extent.

[0008] In a possible implementation of the first aspect of the present application, the electronic device comprises a keyboard host and a display; the keyboard host comprises a shell, a first electro-acoustic device and a first sound guide piece; one end of the shell along a first direction is a first end portion, and the display is rotationally connected to the first end portion; a rotation center line of the display relative to the shell is a first straight line, and the first straight line is perpendicular to the first direction. Thus, the structure is simple.

[0009] In a possible implementation of the first aspect of the present application, the first sound guide piece is connected to the display in linkage. In this way, when the user drives the display to rotate relative to the keyboard host, the first sound guide piece can move relative to the shell under the driving of the display, so as to make the second sound guide port in communication with different opening areas of the first sound hole, thereby without the need to additionally set a driving structure for driving the first sound guide piece to move relative to the shell, which is conducive to simplifying the structure of the keyboard host and reducing the manufacturing cost.

[0010] In a possible implementation of the first aspect of the present application, the first sound hole is located at the first end portion. In this way, by setting the first sound hole at the first end portion, it is conducive to setting the first opening area and the second opening area at different positions of the first end portion according to actual needs, thereby facilitating increasing the orientation difference between the first opening area and the second opening area.

[0011] In a possible implementation of the first aspect of the present application, the shell includes a bearing plate, a support plate and a side frame; the bearing plate and the support plate are oppositely arranged in the thickness direction of the keyboard host, and the side frame is arranged around the bearing plate and the support plate; the keyboard host further includes a keyboard, which is fixedly connected with the bearing plate; the first opening region is located in the side frame, and the second opening region is located in the bearing plate. In this way, the orientation of the first opening region is greatly different from the orientation of the second opening region, which is beneficial to picking up sound in different directions when the first electro-acoustic device is a microphone, thereby improving the sound pickup effect, and is beneficial to sound emission in different directions when the first electro-acoustic device is a loudspeaker, thereby improving the sound emission effect.

[0012] In a possible implementation of the first aspect of the present application, the bearing plate includes a first body and a first protruding plate, the first protruding plate is arranged at one end of the first body close to the first straight line in the first direction, and protrudes from the first body in the first direction, and the second opening region is located on the first protruding plate. In this way, the layout space of the first protruding plate can be fully utilized, and the structure of the electronic device can be reasonably optimized.

[0013] For example, the first electro-acoustic device and the first protruding plate overlap in the vertical projection of the bearing plate, and the first sound guide and the first protruding plate overlap in the vertical projection of the bearing plate. In this way, the first electro-acoustic device and the first sound guide can be arranged close to the first sound transmission hole, thereby shortening the sound transmission path between the first sound transmission hole and the first electro-acoustic device.

[0014] In a possible implementation of the first aspect of the present application, the first sound guide is rotationally connected with the shell, and the rotation center line of the first sound guide relative to the shell is parallel to or collinear with the first straight line. When the display rotates relative to the first end portion, the first sound guide rotates relative to the shell. In this way, the structure layout of the electronic device can be further optimized, and the compactness of the internal structure of the keyboard host can be improved.

[0015] In a possible implementation of the first aspect of the present application, the rotation direction of the first sound guide relative to the shell is opposite to the rotation direction of the display relative to the shell. In this way, when the angle between the display and the shell is small, the second sound guide hole is in communication with the first opening region, and when the angle between the display and the shell is large, the second sound guide hole is in communication with the second opening region, which is beneficial to improving the sound pickup effect when the first electro-acoustic device is a microphone, and is beneficial to improving the sound emission effect when the first electro-acoustic device is a loudspeaker.

[0016] In a possible implementation of the first aspect of the present application, the electronic device further includes a reversing transmission assembly connected between the display and the first sound guide, so that the rotation direction of the display relative to the shell is opposite to the rotation direction of the first sound guide relative to the shell. In this way, the structure is simple.

[0017] In a possible implementation of the first aspect of the present application, the reversing transmission assembly comprises a first gear and a second gear, the first gear is fixed relative to the display; the second gear is located in the shell and is fixedly connected with the first sound guide, and the second gear is in meshing cooperation with the first gear. In this way, by providing the reversing transmission assembly with the first gear and the second gear in meshing cooperation, the first gear is fixed relative to the display, and the second gear is fixedly connected with the first sound guide, so that the structure is simple, easy to manufacture, and conducive to reducing manufacturing cost.

[0018] In a possible implementation of the first aspect of the present application, the shell has a mounting hole; the electronic device further comprises a rotating shaft mechanism, the rotating shaft mechanism comprises a first rotating member and a second rotating member, the first rotating member passes through the mounting hole, one end of the first rotating member located outside the shell is fixedly connected with the display, the second rotating member is located in the shell and is fixedly connected with the shell, and the second rotating member rotates relative to the first rotating member; the first gear is located in the shell and is fixedly connected with the part of the first rotating member located in the shell. In this way, the structural strength of the shell can be improved, and the protection reliability of the shell to the structure inside the keyboard host can be improved, and the structure is compact.

[0019] In a possible implementation of the first aspect of the present application, when the electronic device is in the first state, the angle between the display and the shell is less than α1; when the electronic device is in the second state, the angle between the display and the shell is greater than α2; wherein α1 is less than α2, and α1 is greater than 0. In this way, the second sound guide opening is in communication with the first opening area when the angle between the display and the shell is small, and the second sound guide opening is in communication with the second opening area when the angle between the display and the shell is large, which is conducive to picking up sound in different directions when the first electro-acoustic device is a microphone, improving the sound pickup effect, and is conducive to emitting sound in different directions when the first electro-acoustic device is a loudspeaker, improving the sound emission effect. In addition, it is also conducive to realizing different recording functions of the electronic device by using the communication of the second sound guide opening with different opening areas.

[0020] In a possible implementation of the first aspect of the present application, when the electronic device is in the second state, the vertical projection of the second opening area and the vertical projection of the display do not overlap in the plane parallel to the first direction and parallel to the first straight line. In this way, the display can be prevented from shielding the second opening area.

[0021] In a possible implementation of the first aspect of the present application, α1 is less than or equal to 45°. In this way, the second opening area can be prevented from being shielded due to the opening and closing of the display.

[0022] In a possible implementation manner of the first aspect of the present application, the alpha 2 is greater than or equal to 90°. In this way, the first opening area can be prevented from being shielded due to the opening and closing of the display.

[0023] In a possible implementation manner of the first aspect of the present application, the first sound hole is provided with a partition portion, the first opening area and the second opening area are separated by the partition portion; when the electronic device is in the third state, the angle between the display and the shell is greater than or equal to alpha 1 and less than or equal to alpha 2, and the partition portion blocks the second sound guide hole. In this way, the structure is simple, the processing of the first opening area and the second opening area is facilitated, and the reliability of the communication between the first opening area and the second opening area and the second sound guide hole can be ensured.

[0024] In a possible implementation manner of the first aspect of the present application, the first sound hole further includes a third opening area, the third opening area is in communication with the first opening area and the second opening area; when the electronic device is in the third state, the angle between the display and the shell is greater than or equal to alpha 1 and less than or equal to alpha 2, and the second sound guide hole is opposite to the third opening area.

[0025] In a possible implementation manner of the first aspect of the present application, the first sound guide member includes a first sound guide portion and a first sound collecting portion;

[0026] The central axis of the first sound guide portion is the rotation center line of the first sound guide member relative to the shell; the first sound collecting portion is fixedly connected with the outer peripheral wall of the first sound guide portion and is in communication with the first sound collecting portion; the second sound guide hole is arranged at one end of the first sound collecting portion away from the first sound guide portion. In this way, the structure is simple and compact, and the communication between the second sound guide hole and different opening areas with the movement of the first sound guide member can be facilitated.

[0027] In a possible implementation manner of the first aspect of the present application, one axial end of the first sound guide portion is open to define the first sound guide hole, and the other axial end of the first sound guide portion is closed; the electronic device further includes a second sound guide member, the second sound guide member is located on the side toward which the first sound guide hole is directed, the second sound guide member is fixed in the shell, the second sound guide member has a third sound guide hole and a fourth sound guide hole, the third sound guide hole is in communication with the sound hole, and the fourth sound guide hole is opposite to and in communication with the first sound guide hole. In this way, the one axial end of the first sound guide portion is open to define the first sound guide hole, so that even if the first sound guide member rotates, the relative positional relationship between the first sound guide hole and the shell will not be changed, and on this basis, the communication between the first sound guide hole and the sound hole of the first electro-acoustic device can be facilitated by using the second sound guide member. Moreover, by arranging the second sound guide member and the first sound guide member and making the second sound guide member and the first sound guide member communicate, not only the communication between the first sound hole and the sound hole is realized, but also the structure compactness of the electronic device can be improved by optimizing the sound guide path according to the structural layout in the shell.

[0028] In a possible implementation of the first aspect, the second sound guide member includes a second sound guide part and a second sound receiving part; the second sound guide part is in the same axial direction as the first sound guide part, an end of the second sound guide part facing the first sound guide part is provided with a fourth sound guide opening, and an end of the second sound guide part away from the first sound guide part is closed; the second sound receiving part is fixedly connected to an outer peripheral wall of the second sound guide part and communicates with the second sound guide part, and a third sound guide opening is provided at an end of the second sound receiving part away from the second sound guide part. Thus, the structure is simple.

[0029] To improve the connection reliability between the fourth sound guide opening and the first sound guide opening, a sealing member is arranged between the first sound guide part and the second sound guide part. For example, the sealing member can be sealing glue or a sealing ring. In this way, the sealing between the first sound guide part and the second sound guide part can be improved.

[0030] In a possible implementation of the first aspect, the electronic device includes a second electro-acoustic device, and the second electro-acoustic device is arranged in the shell; an end of the shell away from the first end part in the first direction is a second end part, and the second end part has a second sound receiving hole, and the second sound receiving hole communicates with a sound hole of the second electro-acoustic device. In this way, by integrating the first electro-acoustic device and the second electro-acoustic device in the electronic device, the first sound receiving hole communicating with the first electro-acoustic device is located at the first end part of the shell, and the second sound receiving hole communicating with the second electro-acoustic device is located at the second end part. In this way, the second sound receiving hole and the first sound receiving hole are relatively far away from each other, so that the audio picked up by the first electro-acoustic device and the second electro-acoustic device is different. In this way, on one hand, the difference can be used to realize different recording effects, and on the other hand, the difference can be used to reliably remove noise, improve the accuracy of extracting human voice, and improve the sound pickup effect of the electronic device.

[0031] In a possible implementation of the first aspect, the second electro-acoustic device is two, and the second sound receiving hole is two, and the two second sound receiving holes are arranged apart from each other, and one second sound receiving hole and one sound hole of the second electro-acoustic device correspondingly communicate.

The recording method is applied to the electronic device including the first electro-acoustic device and the second electro-acoustic device, and the first electro-acoustic device and the second electro-acoustic device are both microphones. The recording method includes: obtaining an angle between the display and the shell; in a case where the angle between the display and the shell is less than α1, if the sound source is at the first position, recording using a sound signal collected by the second electro-acoustic device or recording based on mixing of the sound signal collected by the second electro-acoustic device and a sound signal collected by the first electro-acoustic device, and a mixing ratio of the second electro-acoustic device is greater than a mixing ratio of the first electro-acoustic device; if the sound source is at the second position, recording using a sound signal collected by the first electro-acoustic device or recording based on mixing of the sound signal collected by the second electro-acoustic device and a sound signal collected by the first electro-acoustic device, and a mixing ratio of the second electro-acoustic device is less than a mixing ratio of the first electro-acoustic device; in a case where the angle between the display and the shell is greater than α2, performing noise reduction processing on a sound signal collected by the second electro-acoustic device using a sound signal collected by the first electro-acoustic device, and recording using the sound signal collected by the second electro-acoustic device after the noise reduction processing. Thus, different recording effects can be achieved, and the recording effect of the electronic device is improved.

[0034] In a possible implementation manner of the second aspect, in a case where the angle between the display and the shell is greater than or equal to α1 and less than or equal to α2, recording using a sound signal collected by the second electro-acoustic device.

[0035] In a possible implementation manner of the second aspect, in a case where the angle between the display and the shell is less than α1, if energy of a sound signal collected by the first electro-acoustic device in a preset frequency range is less than energy of a sound signal collected by the second electro-acoustic device in the preset frequency range, the sound source is at the first position, and if the energy of the sound signal collected by the first electro-acoustic device in the preset frequency range is greater than the energy of the sound signal collected by the second electro-acoustic device in the preset frequency range, the sound source is at the second position.

[0072] Please refer to FIG. 1, which is a structural schematic diagram of an electronic device 1000 provided by some embodiments of the present application, wherein the electronic device 1000 is in an open state. In this embodiment, the electronic device 1000 is a notebook computer. Specifically, the electronic device 1000 includes a display 200, a keyboard host 100, and a hinge mechanism (not shown in the figure).

[0073] It should be noted that FIG. 1 only schematically shows some components included in the electronic device 1000, and actual shapes, actual sizes, actual positions and actual structures of the components are not limited by FIG. 1 and the following drawings. In other examples, the electronic device 1000 can not include the display 200 when the electronic device 1000 is of other types.

[0074] Please continue to refer to FIG. 1, the display 200 includes a display screen 202 and a back cover 201. The back cover 201 is used to protect the display screen 202. The back cover 201 can wrap around the edges of the display screen 202 and the back of the display screen 202.

[0075] In order to improve the structural strength of the electronic device 1000, the back cover 201 is a metal piece. For example, the back cover 201 is an aluminum alloy piece, a magnesium alloy piece, a stainless steel piece, etc. In other embodiments of the present application, in order to reduce the weight of the electronic device 1000, the back cover 201 can also be a plastic piece.

[0076] The display screen 202 is used to display images, videos, etc. The display screen 202 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

Wherein, the target opening angle can be a fixed value between 0° and 360°, or an arbitrary value between 0° and 360°, which is not limited in the present application. In other examples, the rotating shaft mechanism 300 can also not be a damping rotating shaft mechanism 300.

[0080] Please continue to refer to FIG. 1, when the electronic device 1000 is in an open state, the angle between the display surface A1 of the display 200 and the keyboard surface B1 of the keyboard host 100 (i.e., the angle between the display 200 and the keyboard host 100) α is greater than 0° and less than 360°. In this state, the user can control the display of the display 200 by operating the keyboard host 100, and the user can also watch the images or videos displayed by the display 200.

[0081] Please refer to FIG. 2, which is a structural schematic diagram of the electronic device 1000 shown in FIG. 1, wherein the electronic device 1000 is in a closed state. When the electronic device 1000 is in a closed state, the display 200 covers the keyboard host 100, and the display surface A1 of the display 200 faces the keyboard surface B1 of the keyboard host 100, i.e., the angle between them is 0°. In this state, the display surface A1 of the display 200 and the keyboard surface B1 of the keyboard host 100 can be protected from scratching and dust, and the electronic device 1000 can be conveniently stored and carried.

[0082] In order to facilitate the description of each of the following embodiments, an XYZ coordinate system is established for the keyboard host 100. Specifically, the extension direction of the rotation center line (i.e., the first straight line L1) of the relative rotation of the keyboard host 100 and the display 200 is defined as the X-axis direction, the thickness direction of the keyboard host 100 is defined as the Z-axis direction, and the direction perpendicular to the X-axis direction and the Z-axis direction is defined as the Y-axis direction (i.e., the first direction). It can be understood that the coordinate system of the keyboard host 100 can be flexibly set according to actual needs, which is not limited herein. Moreover, in the actual application process of the user, in the open state of the electronic device 1000, the user faces the display surface A1 of the display 200, so that the X-axis direction is the left-right direction of the user, the Y-axis direction is the front-back direction, and the direction along the Y-axis direction, close to the user, is the front direction.

[0083] Please refer to FIG. 2, and also refer to FIG. 3, which is an exploded view of the keyboard host 100 in the electronic device 1000 shown in FIG. 1. In this embodiment, the keyboard host 100 includes a shell 20, a circuit board 40, a keyboard 10, and an electro-acoustic device 50.

[0084] It should be noted that FIG. 3 only schematically shows some components included in the keyboard host 100, and the actual shape, actual size, actual position and actual structure of the components are not limited by FIG. 3 and the following drawings.

[0085] The shell 20 is used to protect the internal structure of the keyboard host 100. When the user uses the electronic device 1000, the keyboard host 100 is in contact with the user or other external structures through the shell 20. This inevitably causes scratches, corrosion and other problems on the outer surface of the shell 20. In order to avoid this technical problem, the shell 20 can have certain wear resistance, corrosion resistance and scratch resistance, or a functional material for wear resistance, corrosion resistance and scratch resistance can be coated on the outer surface of the shell 20.

[0086] One end of the shell 20 along the Y-axis direction is a first end portion D1, and the other end of the shell 20 along the Y-axis direction is a second end portion D2. The rotation center line (i.e., the first straight line L1) of the relative rotation between the keyboard host 100 and the display 200 is close to the first end portion D1 and away from the second end portion D2.

[0087] For example, the first end portion D1 and the second end portion D2 can be divided by the keyboard 10. The first end portion D1 and the second end portion D2 are located on both sides of the keyboard 10 in the Y-axis direction. The portion of the shell 20 located on the side close to the first straight line L1 of the keyboard 10 in the Y-axis direction is referred to as the first end portion D1, and the portion of the shell 20 located on the side away from the first straight line L1 of the keyboard 10 in the Y-axis direction is referred to as the second end portion D2.

[0088] For another example, the first end portion D1 and the second end portion D2 can be divided by the distance dimension from the two end faces of the shell 20 along the Y-axis direction. The portion of the shell 20 within a predetermined distance range from one end face of the shell 20 along the Y-axis direction is the first end portion D1, and the portion of the shell 20 within a predetermined distance range from the other end face of the shell 20 along the Y-axis direction is the second end portion D2. For example, the predetermined distance can be less than or equal to 4 cm. For example, the predetermined distance is 3 cm, 2 cm or 1 cm.

[0089] In some embodiments, the shell 20 can be a structural whole. That is, the shell 20 can be a one-piece structure, and the one-piece shell 20 has higher structural strength and higher processing efficiency.

[0090] In some other embodiments, the housing 20 can also be formed by assembling multiple parts. Please refer to FIG. 3, the housing 20 includes a C shell 21 and a D shell 22. The C shell 21 and the D shell 22 are closed in the Z axis direction to form an internal accommodating space of the housing 20. In this case, the C shell 21 can be between the display 200 and the D shell 22 when the electronic device 1000 is in the closed state. The housing 20 is formed by assembling the C shell 21 and the D shell 22, which can facilitate the machining of the C shell 21 and the D shell 22, simplify the mold structure of the C shell 21 and the D shell 22, reduce the difficulty of forming the C shell 21 and the D shell 22, and further reduce the difficulty of processing and manufacturing the housing 20.

[0091] Specifically, the C shell 21 can be fixedly connected to the D shell 22 by a snap-fit manner. The C shell 21 can also be connected to the D shell 22 by a screw connection. The C shell 21 can also be connected to the D shell 22 by a magnetic attraction. The C shell 21 can also be connected to the D shell 22 by welding. Alternatively, in other embodiments, the C shell 21 can also be fixedly connected to the D shell 22 by glue or adhesive tape. The present application does not make specific limitations in this regard.

[0092] Specifically, please refer to FIG. 3, the C shell 21 includes a bearing plate 211 and a first side frame 212.

[0093] The bearing plate 211 is in the form of a flat plate. The bearing plate 211 is used to bear functional devices such as the keyboard 10. In addition, the bearing plate 211 can also be used to bear the user's hand when the user uses the electronic device 1000, so as to facilitate the user to strike the keyboard 10.

[0094] The material of the bearing plate 211 includes but is not limited to hard plastic, metal, and a combination of plastic and metal. In this way, it is beneficial to improve the structural strength of the bearing plate 211, thereby improving the bearing effect of the bearing plate 211. In order to realize the light weight of the electronic device 1000, the material of the bearing plate 211 can be selected as hard plastic.

[0095] Please refer to FIG. 3, the bearing plate 211 includes a first body 2113 and a first protruding plate 2114. The first body 2113 is in the form of a generally rectangular plate. Of course, the first body 2113 can also be formed in other shapes, which is related to the shape of the electronic device 1000.

[0096] The first protruding plate 2114 is provided at one end of the first body 2113 close to the first straight line L1 in the Y axis direction and protrudes from the first body 2113 in the first direction. The first protruding plate 2114 is two. The two first protruding plates 2114 are arranged apart along the extension direction of the first straight line L1.

[0097] The first side frame 212 is arranged around the edge of the bearing plate 211, that is, the first side frame 212 is arranged along the edges of the first body 2113 and the first protruding plate 2114 and around the edge of the bearing plate 211. When the C shell 21 is engaged with the D shell 22, the first side frame 212 is connected between the bearing plate 211 and the D shell 22. The bearing plate 211 is provided with a plurality of avoiding holes 2111 for avoiding the keycaps 11 on the keyboard 10 mentioned below. The surface of the bearing plate 211 facing away from the D shell 22 is the keyboard surface B1.

[0098] The material of the first side frame 212 includes but is not limited to hard plastic, metal, and the combination of plastic and metal. In this way, the structural strength of the first side frame 212 is improved. In order to realize the lightness of the electronic device 1000, the material of the first side frame 212 can be selected as hard plastic.

[0099] In some embodiments, please continue to refer to FIG. 3, the C shell 21 can be a one-piece structure, that is, the bearing plate 211 and the first side frame 212 are an integral structure. In this way, the processing technology of the C shell 21 is simplified, the processing efficiency of the C shell 21 is improved, the production cost of the C shell 21 is reduced, and the structural strength of the C shell 21 is improved.

[0100] Please continue to refer to FIG. 3, the D shell 22 includes a support plate 221. The support plate 221 is in the form of a flat plate. The material of the support plate 221 includes but is not limited to hard plastic, metal, and the combination of plastic and metal. In this way, the structural strength of the support plate 221 is improved. In order to realize the lightness of the electronic device 1000, the material of the support plate 221 can be selected as hard plastic.

[0101] The support plate 221 and the bearing plate 211 are arranged opposite to each other in the Z-axis direction.

[0102] Please continue to refer to FIG. 3, the support plate 221 includes a second body 2211 and a second protruding plate 2212. The second body 2211 is in the form of a generally rectangular plate. Of course, the second body 2211 can also be formed in other shapes, which is related to the appearance of the electronic device 1000.

[0103] The second protruding plate 2212 is arranged at one end of the second body 2211 close to the first straight line L1 in the Y-axis direction and protrudes from the second body 2211 in the second direction. The second protruding plate 2212 is two. The two second protruding plates 2212 are arranged apart along the extension direction of the first straight line L1.

[0104] The second body 2211 is opposite to the first body 2113 in the Z-axis direction. The opposite in the Z-axis direction between the second body 2211 and the first body 2113 means that the vertical projection of the second body 2211 overlaps with the vertical projection of the first body 2113 in the plane of the XY-axis. The overlap can be complete or partial. Similar descriptions in the following should be understood in the same way and will not be repeated.

[0105] The two second protruding plates 2212 are opposite to the two first protruding plates 2114 in the Z-axis direction.

[0106] When the electronic device 1000 is placed on a bearing surface (for example, a desktop), the support plate 221 can face the bearing surface. In some examples, a support rib (not shown in FIG. 3) can be arranged on the support plate 221. The support rib protrudes from the surface of the support plate 221 away from the bearing plate 211. In this way, when the electronic device 1000 is arranged on the bearing surface, the electronic device 1000 can contact the bearing surface by means of the support rib to isolate the support plate 221 from the bearing surface, so that a heat dissipation space is formed between the support plate 221 and the bearing surface, facilitating the flow of air between the support plate 221 and the bearing surface, so as to facilitate heat exchange between the electronic device 1000 and the air, which can increase the heat dissipation speed of the heat inside the electronic device 1000 and improve the heat dissipation effect of the electronic device 1000. Of course, the present application is not limited thereto, and in other examples, the support rib can also not be arranged on the support plate 221. In this way, the electronic device 1000 can be directly supported on the bearing surface by means of the support plate 221. For example, the support rib can be a plurality of spaced-apart support ribs.

[0107] For example, the D shell 22 is defined by the support plate 221. At this time, the support plate 221 is connected to the first side frame 212, and the first side frame 212 is arranged along the edges of the second body 2211 and the second protruding plate 2212 and surrounds the edges of the support plate 221.

[0108] For another example, the D shell 22 includes the support plate 221 and a second side frame (not shown in the figure). The second side frame is arranged along the edges of the second body 2211 and the second protruding plate 2212 and surrounds the edges of the support plate 221. When the C shell 21 is closed with the D shell 22, the second side frame is connected between the support plate 221 and the C shell 21. At this time, the second side frame is arranged and connected to the first side frame 212 in the Z-axis direction.

[0109] It can be found that, as shown in FIG. 3, the area between the protruding plates on the outer shell 20 forms an avoiding gap K. The avoiding gap K is used to accommodate at least part of the rotating shaft mechanism, thereby facilitating the compactness of the structure of the electronic device 1000.

[0110] It can be understood that, for the side wall of the shell 20, only the first side frame can be included, only the second side frame can be included, or both the first side frame and the second side frame can be included. For the convenience of description, the side wall between the support plate 221 and the bearing plate 211 is collectively referred to as a side frame.

[0111] The keyboard 10 is used for inputting instructions and data. The keyboard 10 includes a keyboard plate 12 and a plurality of keycaps 11. The plurality of keycaps 11 are arranged on the keyboard plate 12 in a spaced manner. The keyboard plate 12 of the keyboard 10 can be fixedly connected to the inner surface of the bearing plate 211. The plurality of keycaps 11 of the keyboard 10 correspond to the plurality of relief holes 2111 on the bearing plate 211 one by one. Each keycap 11 is arranged through the corresponding relief hole 2111.

[0112] The circuit board 40 is used for integrating a control chip. The control chip can include a memory and a processor, etc.

[0113] The memory can be used to store program codes. The memory can also store a Bluetooth address used to uniquely identify the electronic device 1000. In addition, the memory can also store connection data of a terminal device that has been successfully paired with the electronic device 1000 before. For example, the connection data can be a Bluetooth address of the terminal device that has been paired with the electronic device 1000. Based on the connection data, the electronic device 1000 can automatically pair with the terminal device without having to configure a connection with the terminal device, such as performing legality verification, etc. The Bluetooth address can be a media access control (MAC) address. For example, the memory can be a double data rate (DDR) synchronous dynamic random access memory, a universal flash storage (UFS).

[0114] The processor can be configured to execute the above-mentioned application program code, call relevant modules to implement the functions of the electronic device 1000 in the embodiments of the present application. For example, the electronic device 1000 is used for wireless communication function of other electronic devices and the like. The processor can include one or more processing units, for example: the processor can include an application processor (application processor, AP), a modem processor, a graphics processing unit (graphics processing unit, GPU), an image signal processor (image signal processor, ISP), a video codec, a digital signal processor (digital signal processor, DSP), a baseband processor, and / or a neural-network processing unit (neural-network processing unit, NPU) and the like. Among them, different processing units can be independent devices, or can be integrated in one or more processors. For example, the processor of the electronic device 1000 can be a microprocessor.

[0115] The electro-acoustic device 50 is configured to implement the conversion between the sound signal and the electrical signal. Specifically, the electro-acoustic device 50 can be a microphone (also referred to as a microphone). The microphone can function as a sound pickup to convert the sound signal into an audio electrical signal.

[0116] In other examples, the electro-acoustic device 50 can also be a loudspeaker (also referred to as a loudspeaker). The loudspeaker can convert the audio electrical signal into the sound signal. For ease of illustration, the following is described by taking the electro-acoustic device 50 as a microphone, and therefore, the sound pickup mentioned below refers to the action of the microphone. When the electro-acoustic device 50 is a loudspeaker, those skilled in the art can understand that, unlike the sound pickup function of the microphone, the loudspeaker functions as a sound emitting function.

[0117] Referring to FIG. 4, FIG. 4 is a schematic diagram of a cross-sectional structure of the electro-acoustic device 50 shown in FIG. 3. The electro-acoustic device 50 includes a housing 51 and a diaphragm 52.

[0118] The housing 51 is provided with an acoustic hole 511. It is understood that, for the microphone, the acoustic hole 511 can function as an acoustic hole for entering the sound into the housing 51, that is, the acoustic hole 511 is an acoustic hole.

[0119] The diaphragm 52 is configured to pick up the sound wave transmitted into the housing 51 through the acoustic hole 511 corresponding to the diaphragm 52. The diaphragm 52 can be fixedly connected in the housing 51, or can be fixedly connected at the acoustic hole 511. The diaphragm 52 is electrically connected to the circuit board 40, and transmits the sound signal converted into the electrical signal to the circuit board 40.

[0120] The diaphragm 52 includes, but is not limited to, a Micro-Electro-Mechanical System (MEMS) diaphragm, an Electret Condenser Micphone (ECM) diaphragm, or other diaphragm that can receive a sound signal of a sound wave and convert the received sound signal into an electrical signal.

[0121] Specifically, the diaphragm 52 can include a substrate and a piezoelectric ceramic sheet. For example, the substrate can be etched from a single crystal or polycrystalline silicon material. Of course, the substrate can also be processed from other materials. The piezoelectric ceramic sheet can be formed by spraying a piezoelectric material on the surface of the substrate through a spraying process. In other examples, the piezoelectric ceramic sheet is separately formed and then covered on the substrate. When the sound wave is transmitted to the diaphragm 52 through the sound hole 511, the sound wave can cause the diaphragm 52 to bend. When the diaphragm 52 bends, the piezoelectric ceramic sheet generates an acoustic electrical signal. The acoustic electrical signal is transmitted to the circuit board 40 so that the processor on the circuit board 40 processes the acoustic signal.

[0122] Please continue to refer to FIG. 3, the electro-acoustic device 50 is installed in the shell 20. Specifically, the electro-acoustic device 50 can be fixedly connected to the circuit board 40. For example, the electro-acoustic device 50 can be fixedly connected to the circuit board 40 by gluing, clamping or welding. Of course, it can be understood that in other examples, the electro-acoustic device 50 can also be fixedly connected to the surface of the bearing plate 211 facing the support plate 221, or the electro-acoustic device 50 can also be fixedly connected to the surface of the support plate 221 facing the bearing plate 211, or the electro-acoustic device 50 is fixedly connected to the side frame (for example, the first side frame 212 and / or the second side frame) of the shell 20. The electro-acoustic device 50 is electrically connected to the circuit board 40.

[0123] In some embodiments, the electro-acoustic device 50 is located on the side of the keyboard 10 close to the second end D2 along the Y-axis direction. In this way, when the user is facing the display 200, the electro-acoustic device 50 is arranged close to the user, which facilitates the electro-acoustic device 50 to pick up sound.

[0124] The second end D2 of the shell 20 (i.e., the side frame) is provided with a sound passage 23, and the electro-acoustic device 50 communicates with the sound passage 23. In this way, the electro-acoustic device 50 can be used to pick up sound.

[0125] For example, in the specific example shown in FIGS. 2 and 3, the electro-acoustic device 50 is two. The two electro-acoustic devices 50 are spaced apart in the X-axis direction. In other examples, the electro-acoustic device 50 can be four, and the four electro-acoustic devices 50 are arranged in the X-axis direction.

[0126] Although the electro-acoustic device 50 is arranged at the side of the keyboard 10 close to the second end D2 in the Y-axis direction, it is convenient for the electro-acoustic device 50 to pick up the sound near the keyboard host 100. However, since the sound transmission path from the sound passage 23 to the electro-acoustic device 50 is fixed. Therefore, the direction of the electro-acoustic device 50 picking up sound from the sound passage 23 is directional, and the sound pickup effect of the electro-acoustic device 50 is not good.

[0127] To solve the technical problem, in some embodiments, the electro-acoustic device 50 is no longer integrated in the keyboard host 100, but is integrated in the display 200, that is, the display 200 also includes the electro-acoustic device 50. The electro-acoustic device 50 can be installed in the back shell 201. The sound passage 23 is arranged on the display screen 202. Specifically, the sound passage 23 can be arranged at the end of the display screen 202 away from the rotation center line of the display 200 and the keyboard host 100. In this way, on the one hand, the angle between the display 200 and the keyboard host 100 can be adjusted by the rotation of the display 200 relative to the keyboard host 100, thereby adjusting the sound pickup direction of the electro-acoustic device 50. For example, the electro-acoustic device 50 can be arranged side by side with the camera in the display 200.

[0128] However, for the electronic device 1000, the thickness of the display 200 is generally thin, and the user's demand for the thinness of the electronic device 1000 is increasingly strong. Therefore, when the electro-acoustic device 50 is integrated in the display 200, in order to consider the thinness, a sealing sleeve cannot be arranged between the electro-acoustic device 50 and the region of the inner surface of the display screen 202 surrounding the sound passage 23. This results in poor sealing of the electro-acoustic device 50, which affects the sound pickup effect of the electro-acoustic device 50 and the service life of the electro-acoustic device 50. Moreover, the arrangement of the sound passage 23 occupies the display area of the display 200, reducing the screen-to-body ratio of the display 200.

[0129] To solve at least one of the technical problems existing in the above-mentioned electronic device 1000, please refer to FIG. 5 and FIG. 6, FIG. 5 is a perspective view of another electronic device 1000 provided by the present application, and FIG. 6 is an enlarged view of the part circled at A in the keyboard host 100 shown in FIG. 5. It is worth noting that in order to show the sound guide structure 60 and the circuit board 40 and other components, part of the shell 20 (the part drawn with dotted lines) is not shown in FIG. 5 and FIG. 6.

[0130] The difference between this embodiment and the above-mentioned embodiments is that the first end D1 has a first sound hole 24. In other embodiments, the first sound hole 24 can also be arranged at other positions of the shell 20, for example, at the second end D2, or at positions on the shell 20 on both sides of the keyboard 10 in the X-axis direction, etc.

[0131] Please continue to refer to FIG. 6, the first sound hole 24 has a first opening area 241 and a second opening area 242.

[0132] The orientations of the first opening area 241 and the second opening area 242 are different.

[0133] Here, it is emphasized that the orientations of the first opening area 241 and the second opening area 242 refer to that the center lines of the two opening areas are not parallel, or the walls on which the two opening areas are located are not parallel or coplanar.

[0134] Specifically, in the specific example shown in FIG. 6, the first opening area 241 is located on the side frame 28. The second opening area 242 is located on the bearing plate 211. In this way, the orientation of the first opening area 241 is greatly different from the orientation of the second opening area 242. In particular, since the first sound hole 24 is located at the first end D1, and the first opening area 241 is opened on the side frame 28, it is convenient to pick up the sound signal of the side of the first end D1 facing away from the second end D2 by using the first opening area 241.

[0135] Please refer to FIG. 7 and FIG. 8, FIG. 7 is a structural schematic diagram of the keyboard host 100 of the electronic device 1000 according to FIG. 5, and FIG. 8 is an enlarged view of the part circled at B in FIG. 7. The second opening area 242 is arranged on the first protruding plate 2114. In this way, it is beneficial to make full use of the layout space of the first protruding plate 2114, and reasonably optimize the structure of the electronic device 1000.

[0136] The first opening area 241 and the second opening area 242 can not be connected. Specifically, please continue to refer to FIG. 8, and also refer to FIG. 6, the first sound hole 24 is provided with a partition 244. The first opening area 241 and the second opening area 242 are separated by the partition 244. Of course, the present application is not limited to this, and in other embodiments, please refer to FIG. 9, which is a partial schematic diagram of the electronic device 1000 of some other embodiments of the present application. The first opening area 241 and the second opening area 242 can also be connected. Specifically, the first sound hole 24 further includes a third opening area 243. The third opening area 243 is located between the first opening area 241 and the second opening area 242. The third opening area 243 connects the first opening area 241 and the second opening area 242. In the following description, the structure of the electronic device 1000 is mainly described by taking the first opening area 241 and the second opening area 242 as an example, which are not connected, and the first sound hole 24 is provided with a partition 244.

[0137] When the first opening area 241 and the second opening area 242 are not communicated, the shape of the first opening area 241 includes, but is not limited to, a circle, a rectangle, a rounded rectangle, a triangle, an ellipse or a special shape, and the shape of the second opening area 242 includes, but is not limited to, a circle, a rectangle, a rounded rectangle, a triangle, an ellipse or a special shape.

[0138] Referring back to FIG. 6, the keyboard host 100 includes a first electro-acoustic device 50a and a sound guide structure 60.

[0139] Specifically, the first electro-acoustic device 50a and the sound guide structure 60 are both mounted in the housing 20.

[0140] The first electro-acoustic device 50a can be a microphone or a loudspeaker.

[0141] The first electro-acoustic device 50a can be fixedly connected to the circuit board 40. The fixed connection between the first electro-acoustic device 50a and the circuit board 40 includes, but is not limited to, gluing, welding, clamping or screwing.

[0142] Referring to FIG. 10 and FIG. 11, FIG. 10 is an assembly schematic diagram of the sound guide structure 60, the circuit board 40 and the first electro-acoustic device 50a in the electronic device 1000 according to FIG. 6, and FIG. 11 is a sectional structure schematic diagram of the structure according to FIG. 10 at B-B line.

[0143] The sound guide structure 60 has a sound guide channel 6h. The sound guide channel 6h is communicated with the sound hole 511 of the first electro-acoustic device 50a and the first sound hole 24. In this way, sound waves can be transmitted to the first electro-acoustic device 50a through the first sound hole 24 and the sound guide channel 6h in turn, and then picked up by the first electro-acoustic device 50a.

[0144] Referring back to FIG. 10 and FIG. 11, the sound guide structure 60 includes a first sound guide piece 61.

[0145] It can be understood that FIG. 10 and FIG. 11 only schematically show some components included in the sound guide structure 60, and the actual shape, actual size, actual position and actual structure of these components can be the same as or different from those in FIG. 10 and FIG. 11 and the following drawings.

[0146] The material of the first sound guide piece 61 includes, but is not limited to, metal, plastic and a combination of the two.

[0147] The first sound guide piece 61 has a first channel. The first sound guide piece 61 has a first sound guide opening 613 and a second sound guide opening 614 communicated with the first channel. The opening shape of the first sound guide opening 613 includes, but is not limited to, a circle, a rectangle, an ellipse or a special shape. The opening shape of the second sound guide opening 614 includes, but is not limited to, a circle, a rectangle, an ellipse or a special shape.

[0148] The first sound guide hole 613 is in communication with the sound hole 511 of the first electro-acoustic device 50a.

[0149] When the electronic device 1000 is in the first state, the second sound guide hole 614 is opposite to the first opening area 241. In this way, in the first state, the second sound guide hole 614 can be in communication with the first opening area 241.

[0150] The second sound guide hole 614 being opposite to the first opening area 241 means that the vertical projection of the second sound guide hole 614 on the first opening area 241 overlaps the first opening area 241. In the following, similar descriptions should be understood in the same way.

[0151] When the electronic device 1000 is in the second state, the second sound guide hole 614 is opposite to the second opening area 242. In this way, in the second state, the second sound guide hole is in communication with the second opening area 242.

[0152] For example, the first sound guide member 61 is rotationally connected to the shell 20, so as to switch the second sound guide hole 614 between the first state and the second state.

[0153] When the second sound guide hole 614 is in communication with the first opening area 241, sound waves can enter the sound guide channel 6h through the first opening area 241, and then be picked up by the first electro-acoustic device 50a; when the second sound guide hole 614 is in communication with the second opening area 242, sound waves can enter the sound guide channel 6h through the second opening area 242, and then be picked up by the first electro-acoustic device 50a. Since the first opening area 241 and the second opening area 242 are oriented differently, this is conducive to adjusting the sound pickup direction of the first electro-acoustic device 50a at least to some extent, thereby facilitating the pickup effect of the first electro-acoustic device 50a on sound waves at least to some extent. In addition, it is also conducive to utilizing the communication of the second sound guide hole 614 with different opening areas to realize different recording functions of the electronic device 1000 according to the actual sound source position.

[0154] In other embodiments, the first sound guide member 61 can also be movable relative to the shell 20. Alternatively, in other embodiments, the first sound guide member 61 can be both movable and rotatable relative to the shell 20. As long as the first sound guide member 61 is movable relative to the shell 20 to switch the second sound guide hole 614 between the first state and the second state.

[0155] For example, the first electro-acoustic device 50a is located in the vertical projection of the carrier plate 211 within the vertical projection of the first protruding plate 2114. For another example, a part of the vertical projection of the first electro-acoustic device 50a overlaps a part of the vertical projection of the first protruding plate 2114.

[0156] For example, the first electro-acoustic device 50a is located in the vertical projection of the carrier plate 211 within the vertical projection of the first protruding plate 2114. For another example, a part of the vertical projection of the first electro-acoustic device 50a overlaps a part of the vertical projection of the first protruding plate 2114.

[0157] For example, the first electro-acoustic device 50a is located in the vertical projection of the carrier plate 211 within the vertical projection of the first protruding plate 2114. For another example, a part of the vertical projection of the first electro-acoustic device 50a overlaps a part of the vertical projection of the first protruding plate 2114.

[0158] On this basis, in order to drive the movement of the first sound guide 61 relative to the shell 20, in some embodiments, the first sound guide 61 is connected with the display 200 in linkage. Specifically, when the display 200 rotates relative to the first end D1, the first sound guide 61 rotates relative to the shell 20. In this way, when the user drives the display 200 to rotate relative to the keyboard host 100, the first sound guide 61 can rotate relative to the shell 20 under the drive of the display 200, so as to make the electronic device 1000 in different states, and further make the second sound guide hole 614 communicate with different opening areas of the first sound hole 24, thereby eliminating the need to additionally set a driving structure for driving the movement of the first sound guide 61 relative to the shell 20, and facilitating the simplification of the structure of the keyboard host 100 and the reduction of manufacturing cost.

[0159] On this basis, in order to further optimize the structural layout of the electronic device 1000 and improve the compactness of the internal structure of the keyboard host 100, the rotation center line of the first sound guide 61 relative to the shell 20 is parallel or collinear with the first straight line L1.

[0160] It can be understood that, referring back to FIG. 6, when the electronic device 1000 is in a closed state or an almost closed state, since the second opening area 242 is located on the carrier plate 211, in this state, the second opening area 242 is covered by the display 200 and cannot be picked up or has poor pickup effect. At the same time, since the first opening area 241 is located on the side frame 28, it can be seen that the pickup effect of the first opening area 241 is better than that of the second opening area 242, and the second sound guide hole 614 is best communicated with the first opening area 241.

[0161] Similarly, please refer to FIG. 12 and FIG. 13, FIG. 12 is a schematic diagram of the electronic device 1000 according to FIG. 5, and FIG. 13 is an enlarged view of the portion circled at C according to the structure shown in FIG. 12. When the angle between the display 200 and the housing 20 is large, the second opening area 242 is fully exposed in this state because the second opening area 242 is located at the bearing plate 211. At the same time, the end of the display 200 adjacent to the first end D1 is prone to block the first opening area 241 and fail to pick up sound because the first opening area 241 is located at the side frame 28. At this time, the sound pickup effect of the first opening area 241 is worse than that of the second opening area 242, and the second sound guide hole 614 is best communicated with the second opening area 242.

[0162] Based on this, in some embodiments, the rotation direction of the display 200 relative to the housing 20 is opposite to the rotation direction of the first sound guide 61 relative to the housing 20. In this way, it is beneficial to communicate the second sound guide hole 614 with the first opening area 241 when the angle between the display 200 and the housing 20 is small, and to communicate the second sound guide hole 614 with the second opening area 242 when the angle between the display 200 and the housing 20 is large, so as to improve the sound pickup effect of the first electro-acoustic device 50a, thereby being beneficial to prevent the blockage of one of the first opening area 241 and the second opening area 242 due to the opening and closing of the display 200, and being beneficial to improve the sound pickup effect. In addition, it is also beneficial to utilize the communication of the second sound guide hole 614 with different opening areas to realize different recording functions of the electronic device 1000 according to the actual sound source position.

[0163] On this basis, in some embodiments, please continue to refer to FIG. 6. In the first state, the angle between the display 200 and the housing 20 is less than α1, and the second sound guide hole 614 is communicated with the first opening area 241. In the third state, the angle between the display 200 and the housing 20 is greater than or equal to α1 and less than or equal to α2, and the partition 244 covers the second sound guide hole 614, so that the first electro-acoustic device 50a does not pick up sound. Please continue to refer to FIG. 13. In the second state, when the angle between the display 200 and the housing 20 is greater than α2, the second sound guide hole 614 is communicated with the second opening area 242, wherein α1 is less than α2 and greater than 0.

[0164] In this way, the second sound guide hole 614 is in communication with the first opening area 241 when the angle between the display 200 and the housing 20 is small, and the second sound guide hole 614 is in communication with the second opening area 242 when the angle between the display 200 and the housing 20 is large, so as to improve the sound pickup effect of the first electro-acoustic device 50a, thereby facilitating the prevention of the shielding of one of the first opening area 241 and the second opening area 242 due to the opening and closing of the display 200, and improving the sound pickup effect. In addition, the second sound guide hole 614 can be in communication with different opening areas to realize different sound recording functions of the electronic device 1000.

[0165] It should be noted that in other embodiments, when the first sound hole 24 includes the third opening area 243 described above, in the third state, the angle between the display 200 and the housing 20 is greater than or equal to α1 and less than or equal to α2, and the second sound guide hole 614 is opposite and in communication with the third opening area 243.

[0166] In some embodiments, α1 is less than or equal to 45°. In this way, the shielding of the second opening area 242 due to the opening and closing of the display 200 can be prevented, and the sound pickup effect can be improved.

[0167] For example, α1 can be 44°, 42°, 40°, 39°, 38°, 35°, 32°, 30°, 29°, 28°, 27°, 26°, 25°, 22°, 20°, 18°, 15°, 10°, or 5°.

[0168] In some embodiments, α2 is greater than or equal to 90°. In this way, the shielding of the first opening area 241 due to the opening and closing of the display 200 can be prevented, and the sound pickup effect can be improved.

[0169] For example, α2 can be 92°, 95°, 97°, 100°, 102°, 105°, 107°, 110°, 115°, 118°, 120°, 122°, 125°, 128°, 130°, 138°, 145°, 150°, or 160°.

[0170] On this basis, for example, α2 can be less than or equal to 130°.

[0171] On this basis, in some embodiments, in the second state, a vertical projection of the second opening area 242 in a plane parallel to the first direction and parallel to the first straight line L1 (i.e., in the XY plane) does not overlap with a vertical projection of the display 200. In this way, the sound pickup effect of the first electro-acoustic device 50a can be prevented from being affected by the shielding of the second opening area 242 by the display 200.

[0172] In addition to the above embodiments, in order to realize the reverse rotation of the first sound guide 61 and the display 200, in some embodiments, please refer to FIG. 14 and FIG. 15, FIG. 14 is an assembly diagram of the rotation shaft mechanism 300, the reversing transmission assembly 70 and the sound guide structure 60 in the electronic device 1000 shown in FIG. 5, and FIG. 15 is a partially exploded schematic view of the structure shown in FIG. 14. The electronic device 1000 further comprises a reversing transmission assembly 70. The reversing transmission assembly 70 is connected between the display 200 and the first sound guide 61, so that the reversing effect of the reversing transmission assembly 70 can be used to make the rotation direction of the display 200 relative to the shell 20 opposite to the rotation direction of the first sound guide 61 relative to the shell 20.

[0173] Please continue to refer to FIG. 14 and FIG. 15, the reversing transmission assembly 70 comprises a first gear 71 and a second gear 72. The first gear 71 is fixed relative to the display 200.

[0174] The second gear 72 is located in the shell 20 and is fixedly connected with the first sound guide 61. The first gear 71 and the second gear 72 are in meshing engagement.

[0175] In this way, by making the reversing transmission assembly 70 comprise the first gear 71 and the second gear 72 in meshing engagement, the first gear 71 is fixed relative to the display 200, and the second gear 72 is fixedly connected with the first sound guide 61, the structure is simple, easy to process and manufacture, and is conducive to reducing the manufacturing cost.

[0176] On the basis of any of the above embodiments, in order to facilitate the fixation of the rotation shaft mechanism 300, please refer to FIG. 7, the shell 20 has a mounting hole 25. Specifically, the first side frame 212 has a mounting hole 25. The shape of the mounting hole 25 includes but is not limited to a circular shape, a square shape, a semicircular shape, or a special-shaped hole. The rotation shaft mechanism 300 is arranged through the mounting hole 25. For example, the mounting hole 25 is provided in two, and the two mounting holes 25 are oppositely arranged. The rotation shaft mechanism 300 is two. The two rotation shaft mechanisms 300 correspond to the two mounting holes 25 one by one. Of course, the present application is not limited to this, and in other embodiments, the rotation shaft mechanism 300 and the mounting hole 25 can also be one.

[0177] Please continue to refer to FIG. 14 and FIG. 15, the rotation shaft mechanism 300 comprises a first rotating member 301, a second rotating member 302 and a damping assembly 303.

[0178] The first rotating member 301 is used to be fixedly connected with the display 200. The first rotating member 301 comprises a rotating support 3011 and a rotating shaft 3012. The rotating shaft 3012 is arranged in the mounting hole 25. The rotating support 3011 is arranged outside the shell 20 and is fixedly connected with the rotating shaft 3012. Specifically, the first rotating member 301 can be fixedly connected with the back cover 201 of the display 200 by means of the rotating support 3011. The fixing mode between the rotating support 3011 and the back cover 201 comprises but is not limited to clamping, welding or screw connection.

[0179] In order to improve the structural strength of the first rotating member 301, the first rotating member 301 is a metal piece. Specifically, the first rotating member 301 is an aluminum alloy piece, a magnesium alloy piece or a stainless steel piece.

[0180] The second rotating member 302 is rotatably connected with the first rotating member 301. The rotation center line between the second rotating member 302 and the first rotating member 301 is the rotation center line between the display 200 and the keyboard host 100, i.e. the first straight line L1. The rotatable connection between the second rotating member 302 and the first rotating member 301 can realize the relative rotation between the display 200 and the keyboard host 100.

[0181] Specifically, the second rotating member 302 is rotatably connected with the rotating shaft 3012. Specifically, the second rotating member 302 is provided with a shaft hole 3021, and the rotating shaft 3012 is arranged in the shaft hole 3021 and rotates in the shaft hole 3021. In other embodiments, the shaft hole can also be arranged on the first rotating member 301, and the rotating shaft 3012 is arranged on the second rotating member 302.

[0182] The second rotating member 302 is arranged in the shell 20 and is fixedly connected with the shell 20. The fixing mode between the second rotating member 302 and the shell 20 comprises but is not limited to gluing, welding, clamping or screw connection.

[0183] In order to improve the structural strength of the second rotating member 302, the second rotating member 302 is a metal piece. Specifically, the second rotating member 302 is an aluminum alloy piece, a magnesium alloy piece or a stainless steel piece.

[0184] The damping assembly 303 is located in the second housing 51 and penetrates the rotating shaft 3012. The damping assembly 303 is used to provide a damping force for the relative rotation of the first rotating member 301 and the second rotating member 302. In this way, the display 200 can be conveniently opened to any angle relative to the keyboard host 100. Of course, in other embodiments, the damping assembly 303 can be defined by the rotating shaft 3012 and the shaft hole, and when the rotating shaft 3012 is in interference fit with the shaft hole, the friction force of the relative rotation of the two can provide a damping force for the relative rotation of the first rotating member 301 and the second rotating member 302. In this way, on the one hand, when the display 200 is rotated relative to the keyboard host 100, a damping feeling can be provided for the user under the action of the damping force, providing the user's use experience; on the other hand, when the user opens the electronic device 1000 to a target angle, the display 200 and the keyboard host 100 can be maintained at the current target angle under the action of the damping force, and the display 200 will not fall back due to gravity, thereby realizing the limiting of the electronic device 1000 at the target angle and improving the stability of the rotating shaft mechanism 300 and the electronic device.

[0185] In combination with the above description, since the rotating shaft mechanism 300 is connected between the shell 20 and the display 200, it is necessary to provide the mounting hole 25 described above on the shell 20. The reversing transmission assembly 70 is connected between the first sound guide member 61 and the display 200, and the first sound guide member 61 is located in the shell 20. In order to realize the assembly of the reversing transmission assembly 70, the shell 20 needs to be additionally provided with a through hole for the reversing transmission assembly 70 to penetrate. In this way, the simultaneous provision of the mounting hole 25 and the through hole on the shell 20 will weaken the structural strength of the shell 20 and affect the protection reliability of the shell 20 to the structure inside the keyboard host 100.

[0186] Therefore, in order to improve the structural strength of the shell 20, improve the protection reliability of the shell 20 to the structure inside the keyboard host 100, and improve the structural compactness, please refer to Figs. 14 and 15 again. The first gear 71 is fixedly connected with the part of the first rotating member 301 located in the shell 20. The connection mode between the first gear 71 and the first rotating member 301 includes but is not limited to gluing, welding, clamping, or screw connection.

[0187] Specifically, the first gear 71 is sleeved on the rotating shaft 3012 described above and is coaxially arranged with the rotating shaft 3012. In this way, the space occupied by the rotating shaft 3012 and the first gear 71 as a whole during rotation can be reduced, thereby facilitating the optimization of the structural layout of the keyboard host 100 and reducing the thickness of the keyboard host 100.

[0188] On the basis of any of the above embodiments, the damping assembly 303 is located on the side of the second rotating member 302 away from the rotating support 3011. The damping assembly 303 comprises a friction pad 3031, an elastic structure 3032, and an adjusting nut 3033.

[0189] The friction pad 3031 is fixedly connected to the rotating shaft 3012 and can rotate with the rotating shaft 3012. The friction pad 3031 is in the form of a sheet. For example, the friction pad 3031 is in the form of a circular sheet. One side of the friction pad 3031 is used to abut against the second rotating member 302. In this way, during rotation of the friction pad 3031 with the rotating shaft 3012, mutual friction between the abutting surfaces of the friction pad 3031 and the second rotating member 302 forms damping.

[0190] In order to facilitate assembly of the friction pad 3031 and the rotating shaft 3012 and ensure that the friction pad 3031 can rotate with the rotating shaft 3012, the friction pad 3031 is provided with a first assembly hole (not shown in FIGS. 14 and 15) for cooperating with the rotating shaft 3012. The first assembly hole penetrates the friction pad 3031 along the X-axis direction, and the shape and size of the first assembly hole are adapted to the shape and size of the cross section of the rotating shaft 3012.

[0191] The elastic structure 3032 is sleeved on the rotating shaft 3012 and is used to apply a force to the friction pad 3031 towards the second rotating member 302, so that the friction pad 3031 and the second rotating member 302 remain in contact.

[0192] In some embodiments, the elastic structure 3032 is a disc spring set comprising a plurality of disc spring pieces arranged in the axial direction of the rotating shaft 3012. The disc spring pieces are provided with second assembly holes (not shown in FIGS. 14 and 15) for sleeving the disc spring pieces on the outside of the rotating shaft 3012. For example, the second assembly holes are circular holes. When the rotating shaft 3012 rotates, the elastic structure 3032 does not rotate with the rotating shaft 3012. It can be understood that, in other embodiments, the elastic structure 3032 can also be a spring, a torsion spring, etc.

[0193] The adjusting nut 3033 is threadedly connected to the rotating shaft 3012 and is located on the side of the elastic structure 3032 away from the friction pad 3031. By rotating the adjusting nut 3033, the elastic structure 3032 can be compressed to apply a force to the friction pad 3031 towards the second rotating member 302. Furthermore, by rotating the adjusting nut 3033, the pre-tightening force of the elastic structure 3032 can be adjusted, and thus the size of the initial rotation damping provided by the rotating shaft mechanism 300 can be adjusted, so that the needs of different damping scenarios can be met, and the application range is wide.

[0194] It can be understood that the structure of the damping assembly 303 is not limited to this, as long as it can provide rotation damping during the rotation of the rotating shaft 3012.

[0195] On the basis of any of the above embodiments, please refer to FIGS. 10 and 11 again, the first sound guide 61 includes a first sound guide part 611 and a first sound transmission part 612.

[0196] The shape of the first sound guide part 611 includes but is not limited to a circular cylinder, an elliptical cylinder, a square cylinder or a special-shaped cylinder.

[0197] The central axis of the first sound guide part 611 extends along the X-axis direction.

[0198] One axial end of the first sound guide part 611 is open to define a first sound guide opening 613, and the other axial end of the first sound guide part 611 is closed. In this way, the first sound guide part 611 is open at one axial end to define the first sound guide opening 613, so that even if the first sound guide 61 rotates, the relative positional relationship between the first sound guide opening 613 and the shell 20 will not change, and on this basis, the first sound guide opening 613 and the sound hole of the first electro-acoustic device 50a can be conveniently communicated by the second sound guide 62 below.

[0199] The first sound transmission part 612 is located at the outer periphery of the first sound guide part 611. The first sound transmission part 612 is connected to the outer peripheral wall of the first sound guide part 611 and communicates with the first sound guide part 611. A second sound guide opening 614 is formed at one end of the first sound transmission part 612 away from the first sound guide part 611. The central axis of the first sound guide part 611 is the rotation center line of the first sound guide 61 relative to the shell 20, so that the second sound guide opening 614 can be conveniently communicated with different opening areas, and the structure is simple and convenient to manufacture.

[0200] On the basis of the above embodiments, in order to realize the communication between the first sound guide opening 613 and the sound hole 511, please continue to refer to FIGS. 10 and 11, the electronic device 1000 further includes a second sound guide 62.

[0201] The second sound guide 62 is located at one side toward which the first sound guide opening 613 faces.

[0202] The material of the second sound guide 62 includes but is not limited to metal, plastic and a combination of the two.

[0203] The second sound guide 62 is located in the shell 20 and is fixedly connected to the shell 20. The second sound guide 62 has a second channel. The second sound guide 62 has a third sound guide opening 623 and a fourth sound guide opening 624 which communicate with the second channel. The opening shape of the third sound guide opening 623 includes but is not limited to a circle, a rectangle, an ellipse or a special shape. The opening shape of the fourth sound guide opening 624 includes but is not limited to a circle, a rectangle, an ellipse or a special shape.

[0204] The third sound guide hole 623 is in communication with the sound hole 511 of the first electro-acoustic device 50a. The fourth sound guide hole 624 is opposite to and in communication with the first sound guide hole 613. Thus, the communication channel described above can be defined by the first channel and the second channel.

[0205] In this embodiment, by arranging the second sound guide 62 and the first sound guide 61, and making the second sound guide 62 and the first sound guide 61 in communication, not only the communication between the first sound hole 24 and the sound hole 511 is achieved, but also the structure of the sound guide structure 60 is optimized according to the structural layout in the housing 20, so that the sound guide structure 60 can be adapted to the structural layout in the housing 20, thereby facilitating the compactness of the electronic device 1000.

[0206] Please continue to refer to FIGS. 10 and 11, the second sound guide 62 includes a second sound guide part 621 and a second sound hole part 622. The axial direction of the second sound guide part 621 is along the X-axis direction. The second sound guide part 621 is arranged at one side of the axial direction of the first sound guide part 611. One end of the second sound guide part 621 facing the first sound guide part 611 is provided with the fourth sound guide hole 624. The other end of the second sound guide part 621 away from the first sound guide part 611 is closed. The second sound hole part 622 is located at the outer periphery of the second sound guide part 621 and in communication with the second sound guide part 621, and the third sound guide hole 623 is arranged at the other end of the second sound hole part 622 away from the second sound guide part 621. Thus, the structure is simple and easy to manufacture.

[0207] In order to improve the connection reliability between the fourth sound guide hole 624 and the first sound guide hole 613, a sealing member 63 is arranged between the first sound guide part 611 and the second sound guide part 621. For example, the sealing member 63 can be sealing glue or a sealing ring.

[0208] In this way, the sealing between the first sound guide part 611 and the second sound guide part 621 can be improved.

[0209] Please continue to refer to FIGS. 10 and 11, the first electro-acoustic device 50a and the sound guide structure 60 are respectively located at both sides of the circuit board 40 in the Z direction, and the circuit board 40 has a through hole 401. The sound hole 511 is in communication with the third sound guide hole 623 through the through hole 401. In this way, the structural layout of the electronic device 1000 can be reasonably optimized.

[0210] For example, the side surface of the second sound hole part 622 facing the circuit board 40 and the circuit board 40 can be sealed and connected by a sealing glue layer.

[0211] For example, the side surface of the first electro-acoustic device 50a facing the circuit board 40 and the circuit board 40 can be sealed and connected by a sealing glue layer.

[0212] Please continue to refer to FIG. 14 and FIG. 15, the second gear 72 is fixedly connected with the first sound guide part 611. And the second gear 72 is coaxially arranged with the first sound guide part 611. In this way, it is beneficial to ensure the compactness of the structure.

[0213] For example, please continue to refer to FIG. 14 and FIG. 15, the second gear 72 is fixedly connected to the axial end of the first sound guide part 611. For another example, the second gear 72 is sleeved on the first sound guide part 611 and is fixedly connected with the first sound guide part 611. For still another example, a plurality of first tooth parts (not shown in the figure) can be arranged on the outer circumferential surface of the first sound guide part 611. The plurality of first tooth parts are arranged at intervals in the circumferential direction of the first sound guide part 611, and the plurality of first tooth parts define the first gear 71.

[0214] On the basis of any of the above embodiments, please refer to FIG. 16, which is a schematic diagram of another perspective of the electronic device 1000 shown in FIG. 5. The electronic device 1000 in this embodiment includes a second electro-acoustic device 50b in addition to the first electro-acoustic device 50a. The second end D2 has a second sound hole 23b. The second sound hole 23b is in communication with the sound hole of the second electro-acoustic device 50b. Among them, the setting position of the second electro-acoustic device 50b and the setting position of the second sound hole 23b can be consistent with the position of the electro-acoustic device and the position of the sound channel of the embodiment shown in FIG. 2 and FIG. 3, which will not be repeated here. In other embodiments, the electronic device 1000 can only include the first electro-acoustic device 50a and does not include the second electro-acoustic device 50b.

[0215] In this example, the second electro-acoustic device 50b is two. The second sound hole 23b is two. The two second sound holes 23b are arranged on the side frame 28 of the second end D2. The two second electro-acoustic devices 50b and the sound holes of the two second sound holes 23b correspond one by one. Of course, it can be understood that in other examples, the second electro-acoustic device 50b can also be one, or three, or more.

[0216] In this way, by simultaneously integrating the first electro-acoustic device 50a and the second electro-acoustic device 50b in the electronic device 1000, since the first sound hole 24 in communication with the first electro-acoustic device 50a is located at the first end D1 of the shell 51, and the second sound hole 23b in communication with the second electro-acoustic device 50b is located at the second end D2, the second sound hole 23b and the first sound hole 24 are relatively far apart, thereby making the audio picked up by the first electro-acoustic device 50a and the second electro-acoustic device 50b have certain differences, which is beneficial to utilize the differences to realize different recording effects of the electronic device 1000, and is also beneficial to utilize the differences to realize reliable removal of noise, improve the accuracy of voice extraction, and improve the sound pickup effect of the electronic device 1000.

[0217] On the basis of the above, in some embodiments, please refer to Fig. 17, which is a schematic diagram of the electrical connection of the processor, the first electro-acoustic device 50a, the second electro-acoustic device 50b and the angle sensor in the electronic device 1000 shown in Fig. 5. The electronic device 1000 further comprises an angle sensor.

[0218] The angle sensor is used to detect the angle between the display 200 and the shell 20.

[0219] For example, the angle sensor can be a Hall-effect angle sensor. The Hall-effect angle sensor measures the change of the magnetic field by using a Hall element, so as to obtain the change of the angle. For example, a magnet is pre-installed in the display 200, and the Hall-effect angle sensor is fixedly connected to the circuit board 40. For another example, a magnet is pre-installed in the shell 20, and the Hall-effect sensor is fixedly connected in the display screen 202. When the display 200 rotates, the magnetic field received by the Hall element from the magnet will also change. By measuring the signal output by the Hall element, the rotation angle of the display 200 can be obtained.

[0220] For example, the angle sensor can be a capacitive angle sensor. The capacitive angle sensor measures the change of the angle by using the change of the capacitance. When the display 200 rotates, the capacitance value of the capacitor connected thereto will also change. By measuring the change of the capacitance value, the opening angle of the display 200 can be obtained.

[0221] For example, the angle sensor can be an optical angle sensor. The optical angle sensor measures the change of the angle by using the optical principle. By the interaction between the photoelectric sensor and the grating disc, the rotation angle of the display 200 can be obtained.

[0222] On the basis of the above, the processor is electrically connected with the angle sensor, the first electro-acoustic device 50a and the second electro-acoustic device 50b. The processor can be used to selectively use the sound signal collected by the first electro-acoustic device 50a and / or the sound signal collected by the second electro-acoustic device 50b to record according to different recording preset programs according to the angle between the display 200 and the shell 20 detected by the angle sensor being in the above three angle intervals.

[0223] In this way, on the one hand, it is beneficial to realize different recording effects of the electronic device 1000 by using the difference between the sound signals of the first electro-acoustic device 50a and the second electro-acoustic device 50b due to the relatively far setting, and it is also beneficial to realize reliable removal of noise and improve the accuracy of voice extraction and improve the pickup effect of the electronic device 1000 by using the difference.

[0224] Exemplarily, different angle intervals can correspond to different recording modes, and different recording modes correspond to different recording preset programs. For example, when the angle between the display 200 and the shell 20 is less than α1, the electronic device enters a first recording mode, for example, the first recording mode is a 3D recording mode. When the angle between the display 200 and the shell 20 is greater than α2, the electronic device enters a second recording mode, for example, the second recording mode is a voice enhancement recording mode. When the angle between the display 200 and the shell 20 is greater than α1 or equal to and less than α2 or equal to, the electronic device enters a third recording mode, for example, the third recording mode is a normal recording mode.

[0225] The structure of the electronic device 1000 provided by some embodiments of the present application is introduced above. The present application also provides a recording method of the electronic device 1000. The recording method is applied to the electronic device 1000 described above. The recording method can control the recording software to start or terminate by the instruction received by the keyboard 10 key, the desktop shortcut command, the touch panel, etc. The recording method can also start when the electronic device 1000 is powered on and terminate when the electronic device 1000 is powered off. In other embodiments, the recording method can also start after the electronic device 1000 is powered on for a first preset time and terminate after the electronic device 1000 is powered off for a second preset time, which is not limited here. The first preset time and the second preset time can be equal or not equal.

[0226] Specifically, please refer to FIG. 18, which is a flow chart of the recording method of the electronic device 1000 shown in FIG. 17. The recording method includes:

[0227] Obtaining the angle between the display 200 and the shell 20.

[0228] When the angle between the display 200 and the shell 20 is less than α1, the position of the sound source is determined. If the sound source is located at the first position, the sound signal collected by the second electro-acoustic device 50b is recorded, or the sound signal collected by the second electro-acoustic device 50b and the sound signal collected by the first electro-acoustic device 50a are mixed and recorded, wherein the mixing ratio of the second electro-acoustic device 50b is greater than that of the first electro-acoustic device 50a. If the sound source is located at the second position, the sound signal collected by the first electro-acoustic device 50a is recorded, or the sound signal collected by the second electro-acoustic device 50b and the sound signal collected by the first electro-acoustic device 50a are mixed and recorded, wherein the mixing ratio of the second electro-acoustic device 50b is less than that of the first electro-acoustic device 50a.

[0229] When the position of the sound source is determined, the energy or intensity of the sound signal collected by the first electro-acoustic device 50a and the second electro-acoustic device 50b in the preset frequency range can be determined.

[0230] For example, the energy of the sound signals collected by the first and second electro-acoustic devices 50a and 50b in a preset frequency range is taken as an example. When the energy of the sound signals collected by the first electro-acoustic device 50a in the preset frequency range is less than the energy of the sound signals collected by the second electro-acoustic device 50b in the preset frequency range, the sound source is located at the first position. That is, at the first position, the energy of the sound signals collected by the first electro-acoustic device 50a in the preset frequency range is less than the energy of the sound signals collected by the second electro-acoustic device 50b in the preset frequency range. When the energy of the sound signals collected by the first electro-acoustic device 50a in the preset frequency range is greater than the energy of the sound signals collected by the second electro-acoustic device 50b in the preset frequency range, the sound source is located at the second position. That is, at the second position, the energy of the sound signals collected by the first electro-acoustic device 50a in the preset frequency range is greater than the energy of the sound signals collected by the second electro-acoustic device 50b in the preset frequency range.

[0231] Specifically, as described above, due to the relatively large distance between the second sound hole 23b and the first sound hole 24, there is a certain difference in sensitivity, intensity and energy of the audio picked up by the first and second electro-acoustic devices 50a and 50b. When the sound source is located at the side of the first end D1 away from the second end D2 (i.e., the second position), at this time, the first opening area 241 is closer to the sound source than the second sound hole 23b. Referring to FIG. 19, which is a comparison chart of the frequency response curves of the first and second electro-acoustic devices 50a and 50b when the angle between the display 200 and the housing 20 is less than a1 and the sound source is located at the side of the first end D1 away from the second end D2, the horizontal axis is frequency, the unit of which is Hz, and the vertical axis is sensitivity, the unit of which is dB. It can be found from FIG. 19 that when the sound source is emitted from the side of the first end D1 away from the second end D2, the sensitivity of the first electro-acoustic device 50a is obviously higher than that of the second electro-acoustic device 50b in each frequency band, and the intensity and energy of the sound signals collected by the first electro-acoustic device 50a are obviously higher than those of the sound signals collected by the second electro-acoustic device 50b. In particular, when the frequency is between 2000 Hz and 80000 Hz, the sensitivity of the first electro-acoustic device 50a is more superior than that of the second electro-acoustic device 50b, and the intensity and energy of the sound signals collected by the first electro-acoustic device 50a are obviously higher than those of the sound signals collected by the second electro-acoustic device 50b.

[0232] Similarly, when the sound source is located at the side of the second end D2 away from the first end D1, or in other words, the sound source is located near the second end D2 (i.e., the first position), at this time, the first opening area 241 is farther away from the sound source than the second sound hole 23b. At this time, the sound picked up by the second electro-acoustic device 50b is more sensitive, stronger and has more energy than the first electro-acoustic device 50a.

[0233] Therefore, in the case that the angle between the display 200 and the shell 20 is less than a1, using the above-mentioned recording method can improve the recording effect.

[0234] Please continue to refer to FIG. 18, in the case that the angle between the display 200 and the shell 20 is greater than a2, the sound signal collected by the first electro-acoustic device 50a is used to denoise the sound signal collected by the second electro-acoustic device 50b, and the denoised second electro-acoustic device 50b sound signal is used for recording.

[0235] Specifically, when the angle between the display 200 and the housing 20 is greater than a2, the second opening area 242 and the second sound hole 23b are both located on the same side of the display 200. And the second opening area 242 is closer to the display 200 than the second sound hole 23b. For this recording scene, a general user sits in front of the electronic device 100 to work. In this way, the sound source is often on the side where the display surface A1 of the display 200 faces. Based on this, in this scenario, in order to verify the noise reduction effect of the above-mentioned noise reduction method, experiments are carried out based on the recording method in the present application. Please refer to FIG. 20, which is a comparison chart of the frequency response curves of the two second electro-acoustic devices 50b of the electronic device 1000 when the angle between the display 200 and the housing 20 is greater than a2, and the sound source is located on the side of the second end D2 away from the first end D1, wherein the sound source is human voice. The sensitivity difference of the sound signals collected by the two second electro-acoustic devices 50b is not large, so the intensity and energy of the sound signals collected by the two second electro-acoustic devices 50b are basically consistent. Please refer to FIG. 21, which is a comparison chart of the frequency response curves of the two second electro-acoustic devices 50b when the angle between the display 200 and the housing 20 is greater than a2, wherein the test environment corresponding to the test results shown in FIG. 20 and the test environment corresponding to the test results shown in FIG. 21 have the same background noise, the only difference is that the human voice sound source is emitted in the test environment corresponding to the test results shown in FIG. 20. In each frequency band, the sensitivity difference of the background noise picked up by the two second electro-acoustic devices 50b is not large, so the intensity and energy of the sound signals collected by the two second electro-acoustic devices 50b are basically consistent. Please refer to FIG. 22, which is a time domain graph when the second electro-acoustic device 50b in the test environment shown in FIG. 20 uses the sound signal collected by the second electro-acoustic device 50b to record when testing, wherein the abscissa represents time, and the ordinate represents amplitude or sound intensity. As indicated by the position of the arrow in FIG. 22, the noise picked up by the second electro-acoustic device 50b is relatively large.

[0236] Please refer to FIG. 23, which is a comparison chart of the frequency response curves of the first electro-acoustic device 50a and the second electro-acoustic device 50b when the angle between the display 200 and the shell 20 is greater than a2, and the sound source is located on the side of the second end D2 that is away from the first end D1. In the frequency band between 200 Hz and 8000 Hz, the sensitivity of the first electro-acoustic device 50a is significantly higher than that of the second electro-acoustic device 50b, and the strength and energy of the sound signal collected by the first electro-acoustic device 50a are significantly higher than those of the sound signal collected by the second electro-acoustic device 50b. In particular, in the high-frequency frequency band between 1000 Hz and 80000 Hz, the sensitivity of the first electro-acoustic device 50a is more superior than that of the second electro-acoustic device 50b, and the strength and energy of the sound signal collected by the first electro-acoustic device 50a are significantly higher than those of the sound signal collected by the second electro-acoustic device 50b. Please refer to FIG. 24, which is a comparison chart of the frequency response curves of the first electro-acoustic device 50a and the second electro-acoustic device 50b when the angle between the display 200 and the shell 20 is greater than a2. The test results shown in FIG. 24 correspond to the same background noise as the test environment corresponding to the test results shown in FIG. 23, and the only difference is that a human voice sound source is emitted in the test environment corresponding to the test results shown in FIG. 23. In each frequency band, the sensitivity of the first electro-acoustic device 50a is not much different from that of the second electro-acoustic device 50b.

[0237] Please refer to FIG. 25, which is a time-domain graph of the sound signal collected by the first electro-acoustic device 50a being used to de-noise the sound signal collected by the second electro-acoustic device 50b, and the de-noised sound signal collected by the second electro-acoustic device 50b being used to record sound, in the test environment shown in FIG. 23. By comparing FIG. 25 with the position indicated by the arrow in FIG. 22, it can be determined that the sound signal collected by the first electro-acoustic device 50a being used to de-noise the sound signal collected by the second electro-acoustic device 50b, and the de-noised sound signal collected by the second electro-acoustic device 50b being used to record sound, has good quality and good de-noising effect.

[0238] From the above description, it can be determined that, based on the difference in human voice picked up by the first electro-acoustic device 50a and the second electro-acoustic device 50b, and the substantially consistent noise, when the angle between the display 200 and the shell 20 is greater than a2, using the sound signal collected by the first electro-acoustic device 50a to de-noise the sound signal collected by the second electro-acoustic device 50b, and using the de-noised sound signal collected by the second electro-acoustic device 50b to record sound, is conducive to the suppression of noise, improves the recording quality, and enhances the clarity of human voice.

[0239] In the above, it can be understood that when the second electro-acoustic device 50b is one and the first electro-acoustic device 50a is one, the sound signal collected by the first electro-acoustic device 50a is processed to reduce noise of the sound signal collected by the second electro-acoustic device 50b, and the sound signal after noise reduction of the second electro-acoustic device 50b is recorded.

[0240] When the second electro-acoustic device 50b is multiple and the first electro-acoustic device 50a is one, the sound signal collected by the first electro-acoustic device 50a is processed to reduce noise of the sound signal collected by the second electro-acoustic device 50b, and the sound signal after noise reduction of the second electro-acoustic device 50b is recorded.

[0241] When the second electro-acoustic device 50b is multiple and the first electro-acoustic device 50a is one, the sound signal collected by the first electro-acoustic device 50a is processed to reduce noise of the sound signal collected by the second electro-acoustic device 50b, and the sound signal after noise reduction of the second electro-acoustic device 50b is recorded.

[0242] When the second electro-acoustic device 50b is multiple and the first electro-acoustic device 50a is one, the sound signal collected by the first electro-acoustic device 50a is processed to reduce noise of the sound signal collected by the second electro-acoustic device 50b, and the sound signal after noise reduction of the second electro-acoustic device 50b is recorded.

[0243] When the second electro-acoustic device 50b is multiple and the first electro-acoustic device 50a is one, the sound signal collected by the first electro-acoustic device 50a is processed to reduce noise of the sound signal collected by the second electro-acoustic device 50b, and the sound signal after noise reduction of the second electro-acoustic device 50b is recorded.

[0244] Of course, the present application is not limited to this, in other embodiments, when the angle between the display 200 and the shell 20 is greater than a2, the sound signal collected by the second electro-acoustic device 50b is processed to reduce noise of the sound signal collected by the first electro-acoustic device 50a, and the sound signal after noise reduction of the first electro-acoustic device 50a is recorded.

[0245] In the above, it can be understood that using one microphone to reduce noise of another microphone belongs to the common double-microphone noise reduction technology in the art, which has become prior art and is well known to those skilled in the art, and will not be described here.

[0246] On the basis of any of the above embodiments, please refer to FIG. 18 again. In the case that the angle between the display 200 and the housing 20 is greater than α1 or equal to and less than α2 or equal to, the sound signal collected by the second electro-acoustic device 50b is recorded.

[0247] Among them, it can be understood that when the second electro-acoustic device 50b is multiple, the sound signal collected by one of the second electro-acoustic devices 50b can be recorded. Alternatively, the sound signal collected by multiple second electro-acoustic devices 50b can be recorded. The mixing ratio between different second electro-acoustic devices 50b can be the same or different.

[0248] It is worth understanding that the specific implementation of the mixing recording of the sound signal using multiple electro-acoustic devices 50 is well known to those skilled in the art.
