Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic devices, and in particular to an electronic device. Background Art

[0002] Foldable smart hardware is a key trend in the current consumer electronics industry. Foldable electronic devices, however, are thicker and can create discomfort, leading to a poor user experience. To maintain a comfortable fit after folding, foldable devices are limited in thickness and width. This also limits the internal space available, making it difficult to accommodate a large number of electronic components. Summary of the Invention

[0003] The present application provides an electronic device with high internal space utilization.

[0004] In a first aspect, embodiments of the present application provide an electronic device. The electronic device includes a first housing, a second housing, a first folding mechanism, a speaker, and a first sensor. The first folding mechanism is connected to the first housing and the second housing, and the first housing and the second housing are relatively unfolded or folded by the first folding mechanism. The first sensor is mounted on the first housing, and the speaker is mounted on the second housing. The speaker includes a magnetic member, and the first sensor is configured to detect the magnetic field strength of the magnetic member, thereby detecting the opening and closing angle of the second housing relative to the first housing based on the magnetic field strength.

[0005] It can be understood that the magnetic part of the reused speaker is used as a magnet for detecting the opening and closing angle of the second shell relative to the first shell. There is no need to set up an additional magnet and the first sensor for cooperation, so as to realize the detection of the opening and closing angle of the second shell relative to the first shell, which is conducive to freeing up a part of the internal space of the electronic device. The freed space can be used to accommodate more electronic devices, and the internal space utilization rate of the electronic device is higher.

[0006] In some possible implementations, when the electronic device is in a closed state, the first sensor and the magnetic member are arranged opposite to each other.

[0007] It is understood that the first sensor can be positioned relative to the magnetic component in such a manner that, along the thickness direction of the electronic device, the projection of the first sensor on the reference plane and the projection of the magnetic component on the reference plane at least partially overlap. The reference plane is perpendicular to the thickness direction of the electronic device. Since the magnetic component has significant magnetic flux leakage in the Z-axis direction, the relative positioning of the first sensor and the magnetic component results in a greater magnetic field intensity detected by the first sensor, leading to better detection accuracy.

[0008] In some possible implementations, a speaker includes a frame, a diaphragm, a voice coil, and a magnetic circuit system. The frame and diaphragm are arranged along the thickness of the electronic device. The diaphragm is fixed to the frame at its periphery. The magnetic circuit system is fixedly connected to the frame. One end of the voice coil is fixedly connected to the side of the diaphragm facing the magnetic circuit system, and the other end is located in the magnetic gap of the magnetic circuit system. The magnetic circuit system includes magnetic components.

[0009] It's understood that the magnetic circuit system not only works with the voice coil to produce sound for the speaker, but also works with the first sensor to detect the angle at which the second housing opens and closes relative to the first. By reusing the magnetic circuit system as a magnet for detecting the angle at which the second housing opens and closes relative to the first, there's no need for a separate magnet to work with the first sensor.

[0010] In some possible implementations, the magnetic circuit system includes a central magnet and edge magnets, wherein the edge magnets surround the central magnet and are spaced apart from the central magnet, and the central magnet and the edge magnets enclose a magnetic gap. The central magnet is a magnetic component.

[0011] It can be understood that the position of the central magnet is roughly in the center of the magnetic circuit system. When the electronic device is in a closed state, further arranging the first sensor and the central magnet relative to each other can make the magnetic field intensity detected by the first sensor larger and the detection accuracy better.

[0012] In some possible implementations, when the electronic device is in a closed state, the magnetic circuit system is located on a side of the diaphragm close to the first shell.

[0013] It is understood that, compared to when the electronic device is in a closed state, the magnetic circuit system can be located on the side of the diaphragm away from the first housing. In this embodiment, the distance between the magnetic circuit system and the first housing is closer, and the distance between the magnetic member and the first sensor is smaller. The magnetic field strength of the magnetic member detected by the first sensor can be greater, which is conducive to improving detection accuracy.

[0014] In some possible implementations, the speaker further includes a magnetic conductive sheet fixed to the basin frame, the magnetic conductive sheet and the magnetic circuit system being arranged opposite to each other. When the electronic device is in a closed state, the first sensor and the magnetic conductive sheet are arranged opposite to each other.

[0015] It is understood that the magnetic conductive sheet can be used to enhance the magnetic field of the magnetic circuit system, thereby increasing the magnetic field strength within the magnetic gap. Compared to a solution without the magnetic conductive sheet, in this embodiment, the voice coil requires less current to move the same displacement.

[0016] In some possible implementations, the electronic device further includes a first magnetic member and a second magnetic member, wherein the first magnetic member is mounted on the first housing and the second magnetic member is mounted on the second housing. When the electronic device is in a closed state, the first magnetic member and the second magnetic member are disposed opposite each other.

[0017] It is understandable that there may be an attractive force between the first magnetic member and the second magnetic member. When the electronic device is in a closed state, the attractive force between the first magnetic member and the second magnetic member may enable the first shell and the second shell to be reliably closed.

[0018] In some possible implementations, the second magnetic member and the speaker are stacked along the thickness direction of the electronic device.

[0019] It is understood that stacking the second magnetic element with the speaker can eliminate the area in the XY plane of the second housing that would otherwise be used to mount the second magnetic element. This area can then be used to mount more electronic components. For example, the area saved from mounting the second magnetic element can increase the rear volume of the speaker, improving its sound performance.

[0020] In some possible implementations, when the electronic device is in a closed state, the second magnetic member is fixed to a side of the speaker close to the first housing.

[0021] It can be understood that, on the one hand, compared to the solution in which the speaker and the second magnetic member are stacked in the XY plane, the second magnetic member is arranged on the side of the speaker away from the second shell. When the electronic device is in a closed state, the distance between the second magnetic member and the first magnetic member is smaller, and the suction force between the two is greater, which is beneficial to the closing reliability of the electronic device. On the other hand, compared to the solution in which the speaker and the second magnetic member are stacked in the XY plane, when the electronic device is in a closed state, the distance between the second magnetic member and the first magnetic member is smaller, and the suction force between the second magnetic member and the first magnetic member remains unchanged, the volume of the second magnetic member in this embodiment can be smaller, which is beneficial to reducing the mass of the electronic device.

[0022] In some possible implementations, the electronic device further includes a magnetic isolation sheet, which is fixed to the speaker and located between the second magnetic attraction component and the magnetic component.

[0023] It can be understood that by providing the magnetic isolation sheet, the influence of the second magnetic component on the magnetic component can be reduced, and the interference of the second magnetic component on the operation of the speaker can be reduced.

[0024] In some possible implementations, the housing of the speaker is provided with a mounting groove, an opening of the mounting groove is located on an outer surface of the housing of the speaker, and the second magnetic member is fixed in the mounting groove.

[0025] It can be understood that by setting up the installation groove so that the second magnetic component can be installed in the installation groove, the position of the second magnetic component can be fixed, reducing the risk of the second magnetic component being displaced due to external force, so that the suction force between the first magnetic component and the second magnetic component is maintained within a larger range.

[0026] In some possible embodiments, the speaker housing includes a first sub-housing and a second sub-housing, the first sub-housing and the second sub-housing being arranged along the thickness direction of the electronic device, the first sub-housing being connected to the second sub-housing and enclosing a storage space, and the speaker core being at least partially located in the storage space. The opening of the mounting slot is located on a surface of the first sub-housing facing away from the storage space.

[0027] It is understood that the speaker housing comprises two structural components, a first sub-housing and a second sub-housing, which cooperate to define a housing space within which the speaker core can be at least partially located. The housing is easy to assemble and disassemble, and assembly between the core and the housing is relatively simple.

[0028] In some possible embodiments, the electronic device further includes a third housing and a second folding mechanism, the second folding mechanism being connected to the second housing and the third housing, and the second housing and the third housing being relatively unfolded or folded by the second folding mechanism. The electronic device further includes a second sensor mounted on the third housing, the second sensor being configured to detect the magnetic field strength of the magnetic member, thereby detecting the opening and closing angle of the third housing relative to the second housing based on the magnetic field strength.

[0029] It is understood that by reusing the magnetic field of the speaker's magnetic component, a second sensor can detect the magnetic field strength of the magnetic component, and the electronic device can use the magnetic field strength to detect the opening and closing angle of the third housing relative to the second housing. In a multi-fold electronic device, the number of sensors can be adjusted based on the number of housings in the electronic device, thereby enabling detection of the opening and closing angle between two adjacent housings.

[0030] Some possible embodiments are characterized in that the electronic device further includes a third housing and a second folding mechanism, the second folding mechanism being connected to the second housing and the third housing, and the second housing and the third housing being relatively unfolded or folded by the second folding mechanism. The electronic device further includes a third magnetic member mounted on the third housing, and when the electronic device is in a closed state, the first magnetic member and the second magnetic member are arranged relative to each other.

[0031] It is understandable that there can be attraction between the third magnetic component and the second magnetic component or between the third magnetic component and the first magnetic component. When the electronic device is in a closed state, the attraction between the third magnetic component and the first magnetic component / the second magnetic component can enable the third shell and the second shell to be reliably closed.

[0049] The embodiments of the present application are described below in conjunction with the accompanying drawings. The embodiments described herein with reference to the accompanying drawings are exemplary and intended to be used to explain the present application, and should not be understood as limiting the present application.

[0050] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. It should be understood that in the present application, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship. For example, A and B are connected or A and B are connected, which means that there is a fastening component (such as a screw, bolt, rivet, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0051] Furthermore, the word "fixed" in this article should also be understood in a broad sense. For example, "fixed" can be directly fixed or indirectly fixed through an intermediate medium. Among them, "fixed" means connected to each other and the relative position relationship after connection remains unchanged. The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", etc., are only reference to the directions of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. "Multiple" refers to two or more than two.

[0052] In the description of the embodiments of the present application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in the text is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, “multiple” refers to two or more than two.

[0053] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first," "second," "third," or "fourth" may explicitly or implicitly include one or more of the features.

[0054] In addition, in the embodiments of the present application, the limitations of the relative positional relationship mentioned, such as parallel, vertical, aligned, etc., are all for the current state of the art, rather than being absolutely strict limitations, allowing a small amount of deviation, approximately parallel, approximately vertical, approximately aligned, etc. are all possible. For example, A and B are parallel, meaning that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degree (°) and 10 degrees. For example, A and B are perpendicular, meaning that A and B are perpendicular or approximately vertical, and the angle between A and B can be between 80 degrees and 100 degrees.

[0055] Figure 1 : This is a schematic diagram of the structure of the electronic device 1000 provided in an embodiment of the present application in an open state. It should be noted that the figure only schematically shows some components included in the electronic device 1000, and the actual size, actual position, and actual structure of these components are not limited by the figure. The following figures also only schematically show some components, and the actual size, actual position, and actual structure of these components are not limited by the following figures. The specific details will not be repeated below.

[0056] The electronic device 1000 may be a foldable device such as a mobile phone, a tablet computer, a personal computer, a laptop computer, a vehicle-mounted device, or a wearable device. Figure 1 The electronic device 1000 of the embodiment shown is described by taking a foldable mobile phone as an example. Figure 1 As shown, the width direction of the electronic device 1000 is defined as the X-axis. The length direction of the electronic device 1000 is defined as the Y-axis. The thickness direction of the electronic device 1000 is defined as the Z-axis. In other embodiments, the coordinate system can also be flexibly set according to other requirements.

[0057] Figure 2 yes Figure 1The electronic device 1000 is shown as a schematic diagram of an embodiment in a closed state. Figure 3 yes Figure 1 FIG. 1 is an exploded schematic diagram of an embodiment of an electronic device 1000 shown in FIG.

[0058] like Figure 1 、 Figure 2 and Figure 3 As shown, the electronic device 1000 includes a first housing 100 , a second housing 200 , a screen 300 and a first folding mechanism 400 .

[0059] For example, the first folding mechanism 400 is connected between the first shell 100 and the second shell 200, and the first shell 100 and the second shell 200 can be relatively unfolded or folded by the first folding mechanism 400. Figure 1 It shows that the electronic device 1000 is in an open state. Figure 2 The electronic device 1000 is shown in a folded state.

[0060] It is understandable that the electronic device 1000 includes multiple folding states, and different folding states can be indicated by the opening and closing angles between the first shell 100 and the second shell 200, for example Figure 2 The figure shows a folded state in which the angle between the first housing 100 and the second housing 200 is 0°. The folded state with an opening angle of 0° can also be referred to as the closed state of the electronic device 1000. In other words, the closed state of the electronic device 1000 is a type of folded state of the electronic device 1000. It is understood that due to the precision of the manufacturing and assembly processes, when the electronic device 1000 is in the closed state, the opening angle between the first housing 100 and the second housing 200 can also be 2°, 5°, 10°, etc.

[0061] In some embodiments, the closed state of the electronic device 1000 may also be regarded as a state in which the distance between the first housing 100 and the second housing 200 is the shortest.

[0062] It should be noted that the direction of the rotation axis of the electronic device 1000 is not limited to Figure 2 In other embodiments, the direction of the rotation axis of the electronic device 1000 may also be the Y-axis direction, or other directions.

[0063] For example, when the electronic device 1000 is in an open state, the first housing 100 and the second housing 200 are relatively unfolded, and the first housing 100 and the second housing 200 can be arranged side by side in sequence along the Y-axis direction. When the electronic device 1000 is in a closed state, the first housing 100 and the second housing 200 can be relatively folded, and the first housing 100 and the second housing 200 can be arranged in sequence along the Z-axis direction.

[0064] Screen 300 can be used to display images and videos, etc. It is understood that screen 300 can be an internal screen, an external screen, or a combination of both. When electronic device 1000 is in a closed state, the image displayed on the internal screen cannot be seen from outside electronic device 1000. The external screen can be used to display images when electronic device 1000 is in a closed state.

[0065] Figure 1 and Figure 2 In the example, the screen 300 includes both an inner screen and an outer screen. The screen 300 may include an inner screen 310 (also known as the inner screen) and an outer screen 320 (also known as the outer screen). The inner screen 310 may be spaced apart from the outer screen 320, or they may be connected. Figure 1 and Figure 2 The interval setting between the internal screen 310 and the external screen 320 is taken as an example for introduction.

[0066] It is understandable that Figure 1 For the sake of convenience, the external screen 320 and the first housing 100 are stacked along the Z-axis direction. In other embodiments, the first housing 100 may also surround the external screen 320.

[0067] Exemplarily, the internal screen 310 may include a first display area 311, a second display area 312, and a third display area 313 ( Figure 3 (The figures are distinguished by dotted lines in the figure). The second display area 312 is connected between the first display area 311 and the third display area 313. The second display area 312 can be bent. The first display area 311 is fixed to the first shell 100, the second display area 312 is fixed to the first folding mechanism 400, and the third display area 313 is fixed to the second shell 200. In this way, when the first shell 100 and the second shell 200 are relatively unfolded or folded by the first folding mechanism 400, the second display area 312 can be bent. The first display area 311 and the third display area 313 can overlap each other in the Z-axis direction.

[0068] For example, when the electronic device 1000 is in the open state, the first display area 311, the second display area 312, and the third display area 313 are all located on the same side of the first shell 100 and the second shell 200. For example, the first display area 311, the second display area 312, and the third display area 313 can be approximately 180 degrees (slight deviations are allowed, such as 165 degrees, 177 degrees, or 185 degrees). In this case, the electronic device 1000 has a continuous large display area, that is, the electronic device 1000 can achieve a large screen display, and the user experience is better.

[0069] For example, when the electronic device 1000 is in a folded state, the second display area 312 can be bent. When the electronic device 1000 is in a closed state, the first display area 311 and the third display area 313 overlap each other in the Z-axis direction. At this time, the XY plane size of the electronic device 1000 is small, which is convenient for users to carry and store. Figure 2 It illustrates that when the electronic device 1000 is in a closed state, the first display area 311 and the third display area 313 may be located between the first housing 100 and the second housing 200 .

[0070] Attachment Figure 2 The figure illustrates that when the electronic device 1000 is in a closed state, the first display area 311 and the third display area 313 can be located between the first housing 100 and the second housing 200. In other embodiments, when the screen 300 is an external screen, a portion of the screen 300 can be located on a side of the first housing 100 away from the second housing 200, and a portion of the screen 300 can also be located on a side of the second housing 200 away from the first housing 100. This embodiment is not limited to this.

[0071] For example, the external screen 320 may be provided on a side of the first housing 100 away from the internal screen 310. Figure 2 The diagram illustrates that when the electronic device 1000 is in the closed state, the display surface of the external screen 320 can face the outside of the electronic device 1000. Thus, the external screen 320 can also be used to display images when the electronic device 1000 is closed, and the user can also operate the electronic device 1000 through the external screen 320. In other embodiments, the external screen 320 can also be disposed on a side of the second housing 200 away from the internal screen 310.

[0072] It is understandable that the electronic device 1000 is provided with both an inner screen and an outer screen to meet display requirements of different sizes. When a user needs a larger display area, the first housing 100 and the second housing 200 of the electronic device 1000 can be opened.

[0073] In other implementations, the electronic device 1000 may not include the screen 300 .

[0074] In addition, Figure 1 With attached Figure 2 Each of the above diagrams illustrates that the electronic device 1000 can be folded once. In other embodiments, the electronic device 1000 can also be folded multiple times. The multiple-foldable electronic device 1000 will be described later with reference to the accompanying drawings and will not be described in detail here.

[0075] like Figure 3As shown, the electronic device 1000 may further include a speaker 500 , a first sensor 600 , a first magnetic member 700 , and a second magnetic member 800 .

[0076] For example, the first sensor 600 may be installed on the first housing 100 , and the speaker 500 may be installed on the second housing 200 .

[0077] For example, the speaker 500 is also called a "speaker" and is used to convert an audio electrical signal into a sound signal. The electronic device 1000 can listen to music or listen to hands-free calls through the speaker 500.

[0078] Figure 4 yes Figure 3 A structural diagram of an embodiment of a speaker 500 is shown in FIG. Figure 5 yes Figure 4 FIG. 5 is a cross-sectional view of one embodiment of a loudspeaker 500 at section line AA.

[0079] like Figure 4 and Figure 5 As shown, the speaker 500 may include a magnetic member 510. The magnetic member 510 may be made of a magnetic material, such as a magnet.

[0080] The first sensor 600 can be used to detect the magnetic field strength of the magnetic member 510 of the speaker 500, so as to detect the opening and closing angle of the second housing 200 relative to the first housing 100 through the magnetic field strength. For example, the electronic device 1000 may further include a processor (not shown). The processor can detect the opening and closing angle between the first housing 100 and the second housing 200 based on the magnetic field strength detected by the first sensor 600, and the electronic device 1000 can perform corresponding actions based on the opening and closing angle between the first housing 100 and the second housing 200.

[0081] It is understood that the magnetic member 510 of the multiplexed speaker 500 serves as a magnet for detecting the opening and closing angle of the second housing 200 relative to the first housing 100, eliminating the need for a separate magnet to cooperate with the first sensor 600. This frees up some of the internal space of the electronic device 1000 to accommodate more electronic components (e.g., a camera module, fingerprint module, battery, antenna, sensor, etc.), resulting in higher internal space utilization of the electronic device 1000.

[0082] For example, when the electronic device 1000 switches from the folded state to the opened state, the pattern originally displayed on the external screen 320 of the electronic device 1000 is adjusted to be displayed on the internal screen 310 .

[0083] For example, when the electronic device 1000 does not include the screen 300 or the external screen 320 , the electronic device 1000 may wake up the screen when the electronic device 1000 switches from the folded state to the opened state.

[0084] In some embodiments, the first sensor 600 may be a Hall sensor or a tunnel magneto-resistance (TMR) sensor.

[0085] Several implementations of the first sensor 600 detecting the magnetic field of the magnetic member 510 of the speaker 500 will be described in detail below with reference to the accompanying drawings.

[0086] Figure 6 yes Figure 4 A partially exploded schematic diagram of an embodiment of a loudspeaker 500 is shown in FIG.

[0087] like Figure 5 and Figure 6 As shown, the speaker 500 may include a first sub-case 520 , a second sub-case 530 , a core 540 , and a flexible circuit board 550 .

[0088] For example, the first sub-shell 520 is connected to the second sub-shell 530. The first sub-shell 520 and the second sub-shell 530 may enclose a receiving space 560. At least a portion of the core 540 may be located in the receiving space 560. For example, the core 540 may be fixed to the second sub-shell 530.

[0089] It is understood that the first sub-shell 520 and the second sub-shell 530 can constitute the outer shell 570 of the speaker 500, which is used to protect the internal components (e.g., the core 540, etc.), thereby improving the operating reliability of the speaker 500. The outer shell 570 is easy to disassemble and assemble, and the assembly between the core 540 and the outer shell 570 is relatively simple.

[0090] For example, the first sub-case 520 can be made of metal, plastic, etc. The second sub-case 530 can also be made of metal, plastic, etc. The materials of the first sub-case 520 and the second sub-case 530 can be the same or different.

[0091] In some embodiments, the first sub-shell 520 may include multiple structural members made of different materials, which is not limited in this application. The second sub-shell 530 may also include multiple structural members made of different materials, which is not limited in this application.

[0092] In other embodiments, the first sub-shell 520 and the second sub-shell 530 may also be integrally formed components. The term "integrated component" refers to the process in which one of the two components is formed and connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connection, or screw connection) to connect the two components.

[0093] Figure 7 yes Figure 6 An exploded schematic diagram of one embodiment of the core 540 is shown in FIG. Figure 8 yes Figure 6 FIG. 5 is a cross-sectional view of one embodiment of the core 540 shown at section line BB.

[0094] like Figure 7 and Figure 6 As shown, the core 540 may include a basket 541, a magnetic circuit system 542, a voice coil 543, and a diaphragm 544. The core 540 may be used to generate sound.

[0095] Illustratively, the frame 541 may include sidewalls 5411 and a bottom plate 5412. The sidewalls 5411 may be connected to the periphery of the bottom plate 5412. The sidewalls 5411 and the bottom plate 5412 may enclose a groove 545. The magnetic circuit system 542 may be installed in the groove 545. Illustratively, the frame 541 may be fixed to the second sub-housing 530.

[0096] Exemplarily, the magnetic circuit system 542 may include a central magnet 5421 and edge magnets 5422. The edge magnets 5422 may surround the central magnet 5421 and be spaced apart from the sidewalls 5411 of the central magnet 5421. In other words, there is a spare space between the sidewalls 5411 of the central magnet 5421 and the edge magnets 5422. It is understandable that a magnetic gap 5423 is formed between the sidewalls 5411 of the central magnet 5421 and the edge magnets 5422. At this time, the magnetic gap 5423 has a magnetic field with a certain magnetic field direction. For example, the direction of the magnetic field may be in the direction from the central magnet 5421 to the edge magnet 5422, or in the direction from the edge magnet 5422 to the central magnet 5421.

[0097] It is understood that the shape of the magnetic circuit system 542 is not limited to the shape shown in this application. In other embodiments, the shape of the magnetic circuit system 542 can also be other shapes that can generate a magnetic field to move the voice coil 543.

[0098] In some embodiments, the magnetic circuit system 542 can be fixedly connected to the basin frame 541 . For example, the central magnet 5421 and the edge magnets 5422 can be fixedly connected to the bottom plate 5412 of the basin frame 541 .

[0099] In some embodiments, the magnetic circuit system 542 may include a magnetic member 510. The positional relationship of the magnetic member 510 in the magnetic circuit system 542 will be described in detail below.

[0100] In some embodiments, the voice coil 543 may be partially located outside the magnetic circuit system 542 and partially located within the magnetic gap 5423 of the magnetic circuit system 542 , that is, between the central magnet 5421 and the edge magnet 5422 .

[0101] For example, the voice coil 543 may be annular and may be provided with a central magnet 5421. When current is applied to the voice coil 543, the portion of the voice coil 543 within the magnetic gap 5423 may move along the Z-axis under the action of the magnetic field.

[0102] For example, the voice coil 543 may include a conductive coil (not shown) configured to receive a current related to the audio signal.

[0103] In some embodiments, the diaphragm 544 can be fixed to the frame 541. For example, the diaphragm 544 can be fixed to a side of the sidewall 5411 away from the bottom plate 5412. The voice coil 543 and the magnetic circuit system 542 can be located between the bottom plate 5412 and the diaphragm 544.

[0104] Exemplarily, the periphery 5441 of the diaphragm 544 is fixed to the side wall 5411 of the frame 541. In this way, the force applied to the diaphragm 544 is relatively uniform.

[0105] In some embodiments, the voice coil 543 may be fixed to the diaphragm 544 . For example, one end of the voice coil 543 may be fixedly connected to the side of the diaphragm 544 facing the magnetic circuit system 542 , and the other end may be located in the magnetic gap 5423 of the magnetic circuit system 542 .

[0106] It is understood that when the voice coil 543 is energized, it moves along the Z-axis under the influence of the magnetic field of the magnetic gap 5423, and the voice coil 543 can drive the diaphragm 544 to vibrate along the Z-axis. At this time, the vibration of the diaphragm 544 causes the air near the diaphragm 544 to compress and expand, thereby producing sound.

[0107] In some embodiments, one end of the flexible circuit board 550 can be electrically connected to the voice coil 543 of the core 540, and the other end can be electrically connected to a battery (not shown) of the electronic device 1000. In this way, the battery can power the speaker 500. For example, a portion of the speaker 500 can be located within the receiving space 560 for electrical connection to the voice coil 543, while the other end can extend out of the receiving space 560 for electrical connection to the battery.

[0108] In some embodiments, the core 540 may further include a magnetic conductive sheet 546. The magnetic conductive sheet 546 may be fixedly connected to the basin frame 541. The magnetic conductive sheet 546 may be arranged relative to the magnetic circuit system 542. For example, along the Z-axis direction, the magnetic conductive sheet 546 may be stacked with the magnetic circuit system 542. It is understood that the magnetic conductive sheet 546 can be used to enhance the magnetic field around the magnet, thereby increasing the magnetic field strength within the magnetic gap 5423. Compared to a solution without the magnetic conductive sheet 546, in this embodiment, the current required for the voice coil 543 to move the same displacement is smaller.

[0109] It is understood that the magnetic conductive sheet 546 can be designed based on the shape of the magnet. For example, the magnetic conductive sheet 546 can include a first portion 5461 and a second portion 5462. The second portion 5462 surrounds the first portion 5461 and is spaced apart from the first portion 5461. The first portion 5461 can be positioned opposite the center magnet 5421, and the second portion 5462 can be positioned opposite the edge magnets 5422. The first portion 5461 and the second portion 5462 can enclose a second gap 5463. The second gap 5463 connects to the magnetic gap 5423. A portion of the voice coil 543 can be within the second gap 5463.

[0110] It is understandable that the speaker 500 in the embodiment shown above is a dynamic speaker. That is, the magnetic circuit system 542 is a fixed structural component, and the voice coil 543 moves under the action of the magnetic field of the magnetic circuit system 542 after being energized. In other embodiments, the speaker 500 may also be a dynamic iron speaker. That is, the magnetic circuit system 542 may also be fixed to the diaphragm 544, the voice coil 543 may be fixed to the basin frame 541, the voice coil 543 may generate a magnetic field after being energized, and the magnetic circuit system 542 may move under the action of the magnetic field of the voice coil 543. It is understandable that the type of speaker 500 is not limited in this application.

[0111] Figure 9 yes Figure 2 FIG. 1 is a partial cross-sectional view of an embodiment of electronic device 1000 at section line CC. Figure 9 FIG shows the assembly diagram of the speaker 500 and the first sensor 600 inside the electronic device 1000. It is understandable that Figure 9 In the figure, the magnetic component 510 is taken as an example to be the central magnet 5421 of the magnetic circuit system 542.

[0112] like Figure 9As shown, when the electronic device 1000 is in the closed state, the first sensor 600 can be arranged opposite to the speaker 500. It should be understood that the first sensor 600 and the speaker 500 are arranged opposite to each other, which means that in the thickness direction (Z-axis direction) of the electronic device 1000, the projection of the first sensor 600 on the reference plane and the projection of the speaker 500 on the reference plane at least partially overlap. The reference plane is perpendicular to the thickness direction of the electronic device 1000.

[0113] In some embodiments, other structural components may be provided between the first sensor 600 and the speaker 500, such as the first display area 311 and the third display area 313. In other embodiments, no other structural components may be provided between the first sensor 600 and the speaker 500.

[0114] It is understood that the magnetic field generated by the magnetic member 510 of the speaker 500 in the thickness direction of the electronic device 1000 can be greater than the magnetic field in the XY plane. The first sensor 600 and the speaker 500 are arranged relative to each other. The first sensor 600 can receive and detect more leakage magnetic flux from the magnetic member 510 in the thickness direction of the electronic device 1000, which is used to detect the opening and closing angle of the first shell 100 and the second shell 200. The first sensor 600 has good detection accuracy.

[0115] In other embodiments, the first sensor 600 may not be positioned opposite the speaker 500. That is, in the thickness direction of the electronic device 1000, the projection of the first sensor 600 on the reference plane and the projection of the speaker 500 on the reference plane may be staggered. The first sensor 600 may be positioned at any location on the first housing 100 where it can detect the magnetic field of the magnetic member 510.

[0116] In some embodiments, when the electronic device 1000 is in a closed state, the first sensor 600 can be positioned opposite the magnetic member 510. Positioning the first sensor 600 opposite the magnetic member 510 means that, along the thickness direction of the electronic device 1000, the projection of the first sensor 600 on the reference plane and the projection of the magnetic member 510 on the reference plane at least partially overlap. The reference plane is perpendicular to the thickness direction of the electronic device 1000. It is understood that the magnetic member 510 has a relatively high magnetic flux leakage in the Z-axis direction. Therefore, when the first sensor 600 and the magnetic member 510 are positioned opposite each other, the magnetic field intensity detected by the first sensor 600 is greater, resulting in better detection accuracy.

[0117] In some embodiments, the magnetic circuit system 542 may include a magnetic member 510. For example, the magnetic member 510 may be a central magnet 5421 of the magnetic circuit system 542. The first sensor 600 may be used to detect the magnetic field strength of the central magnet 5421, so that the electronic device 1000 can detect the opening and closing angle of the second housing 200 relative to the first housing 100 based on the magnetic field strength.

[0118] It is understood that the magnetic circuit system 542 can not only be used to cooperate with the voice coil 543 to make the speaker 500 sound, but can also be used to cooperate with the first sensor 600 to detect the opening and closing angle of the second shell 200 relative to the first shell 100. By reusing the magnetic circuit system 542 of the speaker 500 as a magnet for detecting the opening and closing angle of the second shell 200 relative to the first shell 100, there is no need to set up a separate magnet to cooperate with the first sensor 600. This helps to free up a portion of the internal space of the electronic device 1000 to accommodate more electronic components, and the internal space utilization rate of the electronic device 1000 is higher.

[0119] In some embodiments, when the electronic device 1000 is in a closed state, the first sensor 600 can be positioned relative to the central magnet 5421. In other words, along the thickness direction of the electronic device 1000, the projection of the first sensor 600 on the reference plane and the projection of the central magnet 5421 on the reference plane at least partially overlap. It will be appreciated that the central magnet 5421 is positioned approximately at the center of the magnetic circuit system 542. When the electronic device 1000 is in a closed state, further positioning the first sensor 600 and the central magnet 5421 relative to each other can increase the magnetic field intensity detected by the first sensor 600 and improve detection accuracy.

[0120] In other embodiments, the magnetic member 510 may be an edge magnet 5422 of the magnetic circuit system 542. The first sensor 600 may be used to detect the magnetic field strength of the edge magnet 5422. It is understood that when the edge magnet 5422 is the magnetic member 510, the edge magnet 5422 may also be disposed opposite the first sensor 600.

[0121] In other embodiments, the magnetic member 510 may include a central magnet 5421 and an edge magnet 5422. The first sensor 600 may simultaneously detect the magnetic fields of the central magnet 5421 and the edge magnet 5422. A portion of the first sensor 600 may be disposed opposite the central magnet 5421, and a portion may be disposed opposite the edge magnet 5422.

[0122] In some embodiments, the magnetic circuit system 542 may be located on a side of the diaphragm 544 away from the second housing 200. When the electronic device 1000 is in a closed state, the magnetic circuit system 542 may be located on a side of the diaphragm 544 close to the first housing 100. Figure 8 By inverting the core 540 shown in FIG. 5 along the Z-axis, the magnetic circuit system 542 can be located on the side of the diaphragm 544 closer to the first housing 100 when the electronic device 1000 is in a closed state. It will be appreciated that, compared to when the electronic device 1000 is in a closed state, the magnetic circuit system 542 can be located on the side of the diaphragm 544 farther from the first housing 100. In this embodiment, the distance between the magnetic circuit system 542 and the first housing 100 is closer, and the magnetic field strength of the magnetic member 510 detected by the first sensor 600 can be greater, which is conducive to improving detection accuracy.

[0123] Figure 10 yes Figure 3 A structural diagram of an embodiment of the first magnetic attraction component 700 is shown in FIG.

[0124] like Figure 10 As shown, the first magnetic member 700 may be a Halbach magnet array. It is understood that, compared to the first magnetic member 700 having only north and south pole magnets, the Halbach magnet array has a stronger magnetic field strength near the magnets.

[0125] In some embodiments, the first magnetic member 700 may be made of a material that can generate magnetic attraction with a magnet or other magnetic components, such as a ferromagnetic material.

[0126] For example, the first magnetic member 700 may include a first magnet 710, a second magnet 720, and a third magnet 730. The first magnet 710, the second magnet 720, and the third magnet 730 are arranged along the first direction, and the third magnet 730 is located between the first magnet 710 and the second magnet 720. The polarity direction of the first magnet 710 is opposite to the polarity direction of the second magnet 720, and the polarity directions of the first magnet 710, the second magnet 720, and the third magnet 730 are all different ( Figure 10 7. The arrows in FIG. 7 indicate the polarity directions of the first magnet 710, the second magnet 720, and the third magnet 730.

[0127] It is understood that the polarity direction can be the direction from the North Pole (N) to the South Pole (S), or the direction from the South Pole (S) to the North Pole (N). The polarity of one of the first magnet 710 and the second magnet 720 can be the North Pole (N), and the polarity of the other can be the South Pole (S). The first magnet 710 and the second magnet 720 can form an NS magnetic field.

[0128] In other embodiments, the first magnetic member 700 may not include the third magnet 730 , but may only include the first magnet 710 and the second magnet 720 .

[0129] In other embodiments, the first magnetic member 700 may also be formed of a magnet including two parts with opposite polarities, and the magnet may be manufactured using a bipolar magnetization process.

[0130] In some embodiments, the length of the first magnetic member 700 can be in the range of 8 mm to 12 mm, the width can be in the range of 1 mm to 4 mm, and the height can be in the range of 1 mm to 3 mm. For example, the length of the first magnetic member 700 can be 10.3 mm, the width can be 2.6 mm, and the height can be 1.8 mm.

[0131] In some embodiments, the second magnetic member 800 may be a Halbach magnet array. It is understood that when both the first magnetic member 700 and the second magnetic member 800 are configured as Halbach magnet arrays, the attraction between the first magnetic member 700 and the second magnetic member 800 is greater.

[0132] In some embodiments, the first magnetic member 700 may be made of a material that can generate magnetic attraction with a magnet or other magnetic components, such as a ferromagnetic material.

[0133] For example, the second magnetic member 800 may also include a first magnet, a second magnet, and a third magnet. The specific configuration of the first magnet of the second magnetic member 800, the second magnet of the second magnetic member 800, and the third magnet of the second magnetic member 800 can refer to the configuration of the first magnet 710 of the first magnetic member 700, the second magnet 720 of the first magnetic member 700, and the third magnet 730 of the first magnetic member 700, and will not be repeated here.

[0134] In some embodiments, the length of the first magnetic member 700 can be in the range of 8 mm to 12 mm, the width can be in the range of 1 mm to 4 mm, and the height can be in the range of 1 mm to 3 mm. For example, the length of the first magnetic member 700 can be 10.3 mm, the width can be 2.6 mm, and the height can be 1.8 mm.

[0135] In some embodiments, one of the first magnetic member 700 and the second magnetic member 800 may be a magnet, and the other may be a metal member (e.g., an iron block) that can generate attraction with the magnet. In this way, there may also be an attractive force between the first magnetic member 700 and the second magnetic member 800.

[0136] Figure 11 yes Figure 3 FIG. 1 is a schematic diagram of an assembly of a speaker 500 and a second magnetic member 800 according to an embodiment of the present invention. Figure 12yes Figure 2 FIG. 1 is a partial cross-sectional view of yet another embodiment of the electronic device 1000 at section line CC.

[0137] like Figure 11 and Figure 12 As shown, the first magnetic member 700 can be installed on the first housing 100. The second magnetic member 800 can be installed on the second housing 200. When the electronic device 1000 is in a closed state, the first magnetic member 700 can be arranged opposite the second magnetic member 800. In this way, the first magnetic member 700 and the second magnetic member 800 can have an attractive force. When the electronic device 1000 is in a closed state, the attractive force between the first magnetic member 700 and the second magnetic member 800 can ensure that the first housing 100 and the second housing 200 can be reliably closed.

[0138] In some embodiments, the second magnetic member 800 and the speaker 500 may be stacked along the thickness direction of the electronic device 1000 .

[0139] It is understood that stacking the second magnetic member 800 with the speaker 500 can eliminate the area in the XY plane of the second housing 200 that would otherwise be used to mount the second magnetic member 800. This area can then be used to mount more electronic components. For example, the area saved from mounting the second magnetic member 800 can increase the rear volume of the speaker 500, thereby improving the sound performance of the speaker 500.

[0140] In some embodiments, the second magnetic member 800 may be located on a side of the speaker 500 away from the second housing 200. When the electronic device 1000 is in a closed state, the second magnetic member 800 may be located on a side of the speaker 500 close to the first housing 100.

[0141] It can be understood that, compared to the solution in which the speaker 500 and the second magnetic member 800 are stacked in the XY plane, the second magnetic member 800 is arranged on the side of the speaker 500 away from the second housing 200. When the electronic device 1000 is in the closed state, the distance between the second magnetic member 800 and the first magnetic member 700 is smaller, and the suction force between the two is greater, which is beneficial to the closing reliability of the electronic device 1000. On the other hand, compared to the solution in which the speaker 500 and the second magnetic member 800 are stacked in the XY plane, when the electronic device 1000 is in the closed state, the distance between the second magnetic member 800 and the first magnetic member 700 is smaller, and the suction force between the second magnetic member 800 and the first magnetic member 700 remains unchanged. In this embodiment, the volume of the second magnetic member 800 can be smaller, which is beneficial to reducing the mass of the electronic device 1000.

[0142] In other embodiments, the second magnetic member 800 may be located on a side of the speaker 500 close to the second housing 200. When the electronic device 1000 is in a closed state, the second magnetic member 800 may be located on a side of the speaker 500 away from the first housing 100.

[0143] In some embodiments, the second magnetic member 800 can be fixed to the housing of the speaker 500. It is understood that when the first sub-housing 520 and the second sub-housing 530 can constitute the housing of the speaker 500, the second magnetic member 800 can be fixed to the first sub-housing 520 or the second sub-housing 530.

[0144] In some embodiments, the housing 570 of the speaker 500 may be provided with a mounting groove 521. The opening of the mounting groove 521 may be located on the outer surface of the housing 570. The outer surface of the housing 570 refers to the surface facing away from the accommodation space 560. For example, the opening of the mounting groove 521 may be located on the outer surface of the first sub-housing 520. The second magnetic member 800 may be fixed in the mounting groove 521.

[0145] In some embodiments, when the electronic device 1000 is in a closed state, the opening of the mounting slot 521 may face the side where the first housing 100 is located.

[0146] It can be understood that by providing the installation groove 521, the second magnetic component 800 can be installed in the installation groove 521, so that the position of the second magnetic component 800 can be fixed, reducing the risk of the second magnetic component 800 being displaced due to external force, so that the suction force between the first magnetic component 700 and the second magnetic component 800 is maintained within a larger range.

[0147] In some embodiments, the top surface 810 of the second magnetic member 800 can be substantially flush with the top surface 571 of the housing 570. In this way, the second magnetic member 800 is substantially entirely contained within the mounting slot 521, preventing interference between the second magnetic member 800 and other components near the speaker 500.

[0148] In other embodiments, the opening of the mounting groove 521 may also be located on the outer surface of the second sub-shell 530 .

[0149] In some embodiments, the electronic device 1000 may further include a magnetic isolation sheet 950. The magnetic isolation sheet 950 may be fixed to the speaker 500 and located between the second magnetic member 800 and the magnetic member 510. For example, the magnetic isolation sheet 950 may be fixed in the mounting groove 521 and located on a side of the second magnetic member 800 close to the magnetic member 510. It is understood that by providing the magnetic isolation sheet 950, the influence of the second magnetic member 800 on the magnetic member 510 may be reduced, thereby reducing the interference of the second magnetic member 800 with the operation of the speaker 500.

[0150] Exemplarily, the magnetic isolation sheet 950 may be a structure made of magnetic isolation material.

[0151] In other embodiments, the magnetic isolation sheet 950 may also be fixed to the side of the third display area 313 facing the second housing 200 .

[0152] In some embodiments, the present application may also provide a speaker 500. The speaker 500 may include a second magnetic component 800, a first sub-shell 520, a second sub-shell 530, a core 540, and a flexible circuit board 550. In other words, the second magnetic component 800 can be used as a part of the speaker 500. During the assembly of the speaker 500, the assembly with the first sub-shell 520 is completed. Then, when the speaker 500 is installed on the second shell 200, the assembly of the second magnetic component 800 is completed at the same time. This helps to simplify the assembly steps of the electronic device 1000.

[0153] The technical solution of the present application can be applied not only to the electronic device 1000 that folds once as shown in the above embodiment, but also to the electronic device 1000 that folds multiple times. The following will introduce another electronic device 1000 that folds multiple times with reference to the accompanying drawings, and the technical content that is the same as that of the electronic device 1000 in the above embodiment will not be repeated.

[0154] Figure 13 This is a structural diagram of an electronic device 1000 in an open state according to another embodiment of the present application. Figure 14 yes Figure 13 The electronic device 1000 is shown as a schematic structural diagram in a closed state. Figure 15 yes Figure 13 FIG. 1 is an exploded schematic diagram of an embodiment of an electronic device 1000 shown in FIG.

[0155] like Figures 13 and 14 As shown, the electronic device 1000 may include a first housing 100, a second housing 200, a third housing 910, a screen 300, a first folding mechanism 400, a second folding mechanism 920, a speaker 500, a first sensor 600, a second sensor 930, a first magnetic member 700, a second magnetic member 800, and a third magnetic member 940. The arrangement of the first housing 100, the second housing 200, the first folding mechanism 400, the speaker 500, the first sensor 600, the first magnetic member 700, and the second magnetic member 800 may refer to the arrangement of the first housing 100, the second housing 200, the first folding mechanism 400, the speaker 500, the first sensor 600, the first magnetic member 700, and the second magnetic member 800 shown in the previous embodiment, and will not be repeated here.

[0156] For example, the second folding mechanism 920 is connected between the second housing 200 and the third housing 910, and the second housing 200 and the third housing 910 are relatively unfolded or folded by the second folding mechanism. In this way, the first housing 100, the second housing 200, and the third housing 910 can be rotated by the first folding mechanism 400 and the second folding mechanism 920, thereby driving the first display area 311, the second display area 312, the third display area 313, the fourth display area 321, and the fifth display area 322 to rotate, achieving folding in the Z-axis direction. The electronic device 1000 is folded twice.

[0157] For example, the screen 300 may include an internal screen 310 and an external screen 320. The internal screen 310 and the external screen 320 are connected. The internal screen 310 may include a first display area 311, a second display area 312, and a third display area 313. The external screen 320 may include a fourth display area 321 and a fifth display area 322. The fourth display area 321 is fixed to the second folding mechanism 920. The fifth display area 322 is fixed to the third housing 910. In this way, when the second housing 200 and the third housing 910 are relatively unfolded or folded by the second folding mechanism 920, the fourth display area 321 can be bent. The fifth display area 322 and the third display area 313 can overlap with each other in the Z-axis direction.

[0158] For example, when the electronic device 1000 is in the open state, the first display area 311, the second display area 312, the third display area 313, the fourth display area 321, and the fifth display area 322 are all located on the same side of the first shell 100, the second shell 200, and the third shell 910. For example, the first display area 311, the second display area 312, the third display area 313, the fourth display area 321, and the fifth display area 322 can be approximately 180° (slight deviations are allowed, such as 165°, 177°, or 185°). In this case, the electronic device 1000 has a continuous large display area, that is, the electronic device 1000 can achieve a large-screen display, and the user experience is better.

[0159] For example, when the electronic device 1000 is in the closed state, the fourth display area 321 can be bent. The fifth display area 322 overlaps with the third display area 313 in the Z-axis direction. In this case, the XY plane size of the electronic device 1000 is small, making it easier for users to carry and store.

[0160] It is understood that the angles at which the first housing 100 is unfolded or folded relative to the second housing 200 and the second housing 200 relative to the third housing 910 can be the same or different. In other words, the user can, as desired, have the first display area 311, the second display area 312, the third display area 313, the fourth display area 321, and the fifth display area 322 all display images, or only partially display images. For example, the first housing 100 can be opened relative to the second housing 200, and the second housing 200 can be closed relative to the third housing 910, in which case the first display area 311, the second display area 312, and the third display area 313 display images. Alternatively, the first housing 100 can be closed relative to the second housing 200, and the second housing 200 can be closed relative to the third housing 910, in which case the fifth display area 322 can display an image. Alternatively, the first shell 100 can be opened relative to the second shell 200, and the second shell 200 can be opened relative to the third shell 910, and the first display area 311, the second display area 312, the third display area 313, the fourth display area 321 and the fifth display area 322 all display images.

[0161] In some embodiments, the internal screen 310 and the external screen 320 may be a single screen or two independent screens.

[0162] Figure 16 yes Figure 14 FIG. 1 is a schematic structural diagram of an embodiment of an electronic device 1000 at a section line DD.

[0163] like Figure 15 and Figure 16 As shown, the second sensor 930 can be installed on the third housing 910. The second sensor 930 is used to detect the magnetic field strength of the magnetic member 510 of the speaker 500, so as to detect the opening and closing of the third housing 910 relative to the second housing 200. For example, when the electronic device 1000 is in the folded state, the second sensor 930 can be arranged opposite to the magnetic member 510 of the speaker 500.

[0164] It will be appreciated that by providing a speaker 500, a first sensor 600, and a second sensor 930, the speaker 500 may include a magnetic member 510. The first sensor 600 can be used to detect the magnetic field strength of the magnetic member 510 of the speaker 500, thereby detecting the opening and closing angle of the second housing 200 relative to the first housing 100 based on the magnetic field strength. The second sensor 930 is used to detect the magnetic field strength of the magnetic member 510, thereby detecting the opening and closing angle of the third housing 910 relative to the second housing 200 based on the magnetic field strength. In this way, the processor of the electronic device 1000 can determine the opening and closing angle of the first housing 100 relative to the second housing 200 and the opening and closing angle of the second housing 200 relative to the third housing 910 based on the detection results of the first sensor 600 and the second sensor 930. In other words, by multiplexing the magnetic field of the magnetic member 510 of the speaker 500 and the second sensor 930 detecting the magnetic field strength of the magnetic member 510, the electronic device can detect the opening and closing angle of the third housing 910 relative to the second housing 200 based on the magnetic field strength.

[0165] Exemplarily, the processor can also control the first display area 311, the second display area 312, the third display area 313, the fourth display area 321 and the fifth display area 322 according to the opening and closing of the first shell 100 relative to the second shell 200, and the opening and closing of the second shell 200 relative to the third shell 910, and select the appropriate screen for display in different scenarios.

[0166] In some embodiments, the third magnetic member 940 can be mounted on the third housing 910. When the electronic device 1000 is in a closed state, the third magnetic member 940 can be positioned opposite the second magnetic member 800. It is understood that there is an attractive force between the third magnetic member 940 and the second magnetic member 800 or between the third magnetic member 940 and the first magnetic member 700. When the electronic device 1000 is in a closed state, the attractive force between the third magnetic member 940 and the first magnetic member 700 / the second magnetic member 800 can ensure that the third housing 910 and the second housing 200 are securely closed.

[0167] For example, the third magnetic member 940 may be made of a material that can generate magnetic attraction with a magnet or other magnetic components, such as a ferromagnetic material, etc. For example, the third magnetic member 940 may also be a Halbach magnet array.

[0168] It is understandable that at least one of the first magnetic component 700 , the second magnetic component 800 and the third magnetic component 940 is a magnet.

[0169] It is understood that in a foldable electronic device, the third housing 910 is not limited to being located on the side of the second housing 200 away from the first housing 100. In other embodiments, the third housing 910 may also be located on the side of the first housing 100 away from the second housing 200. When the electronic device 1000 is in the closed state, the third housing 910 may also be located on the side of the first housing 100 away from the second housing 200.

[0170] In other embodiments, the electronic device 1000 may be folded in a roughly 6-shaped or 9-shaped configuration. For example, when the electronic device 1000 is in an open state, the third housing 910 may be connected to a side of the second housing 200 that is away from the first housing 100. When the electronic device 1000 is in a closed state, the third housing 910 may be located on a side of the first housing 100 that is away from the second housing 200. This application does not limit the folding method of the electronic device 1000.

[0171] In other embodiments, the electronic device 1000 may be folded more than twice. For example, the electronic device 1000 may be folded three times, forming a "W" shape. The electronic device 1000 may also be folded five times or seven times. It is understood that when the electronic device 1000 is folded multiple times, multiple sensors for detecting the magnetic field strength of the magnetic member 510 may be provided, thereby enabling detection of the degree of opening and closing of each housing.

[0172] In some embodiments, the present application may also provide an electronic device 1000. The electronic device 1000 includes a first shell 100, a second shell 200, a first folding mechanism 400, a speaker 500, a first magnetic member 700 and a second magnetic member 800. The first magnetic member 700 is installed on the first shell 100, and the speaker 500 and the second magnetic member 800 are installed on the second shell 200. The second magnetic member 800 and the speaker 500 are stacked along the thickness direction of the electronic device 1000. The first folding mechanism 400 is connected to the first shell 100 and the second shell 200, and the first shell 100 and the second shell 200 are relatively unfolded or folded through the first folding mechanism 400. When the electronic device 1000 is in a folded state, the first magnetic member 700 and the second magnetic member 800 are relatively arranged.

[0173] In some embodiments, when the speaker 500 does not need to cooperate with the first sensor 600 to realize opening and closing detection, the speaker 500 can also be a speaker type without magnetic parts such as an ultrasonic speaker 500.

[0174] It can be understood that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other, and any combination of features in different embodiments is also within the scope of protection of the present application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0175] It should be understood that all the above drawings are illustrative illustrations of the present application and do not represent the actual size of the product. Moreover, the dimensional ratios between the components in the drawings are not intended to limit the actual product of the present application.

[0176] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
