Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a speaker and electronic equipment. Background Art

[0002] With the advancement of technology and increasing consumer demand for portable devices, electronic devices, such as mobile phones, have become an indispensable part of daily life. However, traditional mobile phone designs present a significant contradiction between screen size and portability. While large screens offer a better user experience, they are also inconvenient to carry and use. Therefore, foldable phones have emerged, combining the advantages of large screens and portability to provide users with a completely new user experience.

[0003] A foldable phone includes a main frame and a sub-frame, which are rotatably connected to each other. The main frame and the sub-frame cooperate with each other to enable the foldable phone to have a folded state and an unfolded state. Magnets installed on the main frame and the sub-frame respectively attract each other to assist the foldable phone in maintaining the folded state. Magnets occupy a certain area and volume, and in some cases, they may conflict with other components of the phone, such as the stacking of speakers. Summary of the Invention

[0004] The present application provides a speaker and an electronic device to solve the technical problem that magnets in foldable mobile phones occupy a certain area and volume and conflict with other components of the mobile phone, such as the stacking of speakers.

[0005] The technical solution is as follows:

[0006] A first aspect of the present application provides an electronic device, comprising: a housing, a first magnetic member, and a speaker;

[0007] The housing includes two sub-housings, which are rotatably connected so that the electronic device can be converted between a folded state and an unfolded state;

[0008] The two sub-shells are respectively equipped with first magnetic members, and the first magnetic members on the two sub-shells cooperate with each other;

[0009] The speaker includes a core, the core including a first magnet;

[0010] At least one of the two sub-shells is installed with a speaker, so that the first magnetic attraction member on the sub-shell on which the speaker is installed forms a first magnet;

[0011] When the electronic device is in the folded state, the first magnetic elements on the two sub-shells attract each other to keep the electronic device in the folded state.

[0012] By adopting the above scheme, at least one magnet is replaced by the first magnet in the speaker, that is, the magnet that provides the suction force for the electronic device in the closed state (i.e., the folded state) is shared with the first magnet in the speaker, so that the suction force for the two sub-shells to remain in the closed state is provided by the first magnet inside the speaker; compared with the related art, the present application can reduce the number of required magnets, which is beneficial to reducing the weight of the electronic device and reducing manufacturing costs; in addition, since the installation of the speaker will not cause stacking conflicts, the structure of the speaker itself can be optimized to improve the audio effect of the speaker; in addition, when the electronic device includes devices such as compasses, Hall switches, magnetoresistive devices, etc. that are very sensitive to magnetic field strength, the number of magnets is reduced, which is beneficial to the position layout design of the above-mentioned magnetic sensitive devices and can reduce the interference of magnets on the above-mentioned devices.

[0013] In some implementations, the electronic device further includes a hinge mechanism, the sub-housing has a first side and a second side opposite to each other, and the first side is connected to the hinge mechanism;

[0014] The direction from the first side to the second side is parallel to the width direction of the subshell;

[0015] The sub-shell includes a first section and a second section connected to the first section. The dividing line between the first section and the second section is the center line of the sub-shell in its own width direction. The first section is connected to the rotating shaft mechanism.

[0016] By adopting the above solution, the hinge mechanism is utilized to facilitate relative rotation between the two sub-shells, thereby realizing folding and unfolding of the electronic device.

[0017] In some implementations, a centerline of the core in the width direction of the subshell is located on the second subsection;

[0018] Alternatively, the center line of the inner core in the width direction of the subshell coincides with the center line of the subshell in its own width direction.

[0019] By adopting the above solution, the first magnet of the core can be kept away from the rotating shaft mechanism in the width direction of the sub-shell, so that the magnetic force of the first magnet can provide a larger torque to ensure that the electronic device remains in a closed state.

[0020] In some implementations, the center line of the core in the width direction of the sub-shell is located on the first section, and the distance between the center line of the core in the width direction of the sub-shell and the center line of the sub-shell in its own width direction is not greater than a first preset value.

[0021] By adopting the above solution, when the inner core is away from the second side and close to the first side, the distance between the center line of the inner core in the width direction of the sub-shell and the center line of the sub-shell in its own width direction is limited, which can also ensure that the electronic device remains in a closed state.

[0022] In some implementations, the first preset value is greater than zero, and the first preset value is no greater than 11 mm.

[0023] By adopting the above solution, selecting a suitable range of the first preset value can also ensure that the electronic device remains in the closed state.

[0024] In some implementations, the subshell has opposing inner and outer sides;

[0025] The distance between the first magnet and the outer side surface is greater than the distance between the first magnet and the inner side surface;

[0026] When the electronic device is in a folded state, the inner side surface is located between the two outer side surfaces.

[0027] By adopting the above solution, the first magnet is closer to the inner side surface, so that the first magnet can provide a larger magnetic force to ensure that the electronic device remains in a closed state.

[0028] In some implementations, the speaker has a rear cavity surface, and the direction of the inner side surface of the sub-housing on which the speaker is mounted is the same as the direction of the rear cavity surface of the speaker on the sub-housing itself.

[0029] By adopting the above solution, after the speaker is installed on the sub-shell, the first magnet is closer to the inner side surface, thereby ensuring that the electronic device remains in a closed state.

[0030] In some implementations, the electronic device further includes a display screen and a back panel;

[0031] The display screen is installed on the inner side, and the back panel is installed on the outer side; or, the display screen is installed on the outer side, and the back panel is installed on the inner side.

[0032] By adopting the above solution, the electronic device can be either an inward-folding electronic device or an outward-folding electronic device, thereby improving the application scenarios of the electronic device in this application.

[0033] In some implementations, the two sub-shells are respectively a first sub-shell and a second sub-shell, and speakers are respectively mounted on the first sub-shell and the second sub-shell;

[0034] The first magnetic member on the first sub-shell forms a first magnet of the speaker on the first sub-shell;

[0035] The first magnetic member on the second sub-shell forms a first magnet of the speaker on the second sub-shell.

[0036] By adopting the above solution, when speakers need to be installed on both sub-shells, the first magnet of the speaker can replace the original magnet in the related art, thereby reducing the number of required magnets and lightening the weight of the electronic device.

[0037] In some implementations, the speaker has a rear cavity surface; when the electronic device is in a folded state, the rear cavity surface of the speaker on the first sub-shell and the rear cavity surface of the speaker on the second sub-shell are arranged to face each other.

[0038] By adopting the above solution, after the speaker is installed on the sub-shell, the first magnet is closer to the inner side surface, thereby ensuring that the electronic device remains in a closed state.

[0039] In some implementations, an orthographic projection of the speaker core on the first sub-housing in the first plane and an orthographic projection of the speaker core on the second sub-housing in the first plane have an overlapping area, and a ratio T of an area of ​​the overlapping area to an area of ​​the orthographic projection of the speaker core in the first plane satisfies the following relationship: 0.2≤T≤1;

[0040] The first plane is perpendicular to the thickness direction of the electronic device.

[0041] By adopting the above solution, a completely overlapping or partially overlapping manner is adopted to ensure the magnetic force of attraction between the two first magnets, thereby ensuring that the electronic device remains in a closed state.

[0042] In some implementations, the speaker further includes a sheet-shaped first magnetic yoke; the first magnetic yoke is disposed on a side surface of the first magnet;

[0043] The first magnet includes a plurality of sub-magnets, and the plurality of sub-magnets are assembled together.

[0044] By adopting the above solution, the first magnetic yoke cooperates with the multiple sub-magnets, which is beneficial to improving the acoustic performance of the speaker.

[0045] In some implementations, a first through hole is formed on the first magnetic yoke, and an opening of the first through hole is arranged opposite to a surface of the sub-magnet;

[0046] Alternatively, a first through hole is formed on the first magnetic conductive yoke, and an opening of the first through hole is arranged opposite to the gap between the two assembled sub-magnets.

[0047] By adopting the above solution, part of the magnetic lines of force of the sub-magnet are no longer constrained by the first magnetic yoke, and these part of the magnetic lines of force can leak to the outside of the first magnetic yoke, thereby increasing the magnetic force required for the electronic device to maintain a closed state without affecting the reliability of the speaker.

[0048] In some implementations, the electronic device further includes a second magnetic member, and the two sub-shells are respectively mounted with the second magnetic member, and the second magnetic members on the two sub-shells cooperate with each other;

[0049] When the electronic device is in the folded state, the second magnetic elements on the two sub-shells attract each other.

[0050] By adopting the above solution, the second magnetic attraction member can further ensure that the electronic device remains in a closed state.

[0051] A second aspect of the present application provides a speaker, applicable to the electronic device in any of the above implementations, the speaker comprising a housing and a core, the housing having a housing cavity, the core being mounted in the housing cavity, the housing cavity being divided by the core into a front cavity and a rear cavity;

[0052] The core includes a first magnet and a first magnetic yoke. The first magnetic yoke is arranged on one side of the first magnet, the one side of the first magnetic yoke faces the first magnet, and the other side opposite to the first magnetic yoke faces the rear cavity. The first magnet includes multiple sub-magnets, and the multiple sub-magnets are spliced ​​together.

[0053] A first through hole is formed on the first magnetic yoke, and the opening of the first through hole is arranged opposite to the surface of the sub-magnet; or, a first through hole is formed on the first magnetic yoke, and the opening of the first through hole is arranged opposite to the gap between the two assembled sub-magnets.

[0054] By adopting the above-mentioned scheme, the first magnet of the speaker can replace the magnet in the related art that provides the suction force for the electronic device to be in a closed state (i.e., a folded state), so that the suction force for the two sub-shells to remain in a closed state is provided by the first magnet inside the speaker; in addition, part of the magnetic lines of force of the sub-magnet are no longer constrained by the first magnetic yoke, and this part of the magnetic lines of force can leak to the outside of the first magnetic yoke, thereby increasing the magnetic force required for the electronic device to remain in a closed state without affecting the reliability of the speaker.

[0077] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0078] It should be understood that the “multiple” mentioned in this application refers to two or more. In the description of this application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships, 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 order to facilitate the clear description of the technical solution of this application, words such as “first” and “second” are used to distinguish between identical or similar items with basically the same functions and effects. Those skilled in the art can understand that words such as “first” and “second” do not limit the quantity and execution order, and words such as “first” and “second” do not necessarily limit them to be different.

[0079] The speaker and electronic device provided in the embodiments of the present application are explained in detail below.

[0080] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of an electronic device in a folded state provided by an embodiment of the present application, Figure 2 is a schematic structural diagram of an electronic device provided in an embodiment of the present application in a semi-expanded state, Figure 3 It is a structural schematic diagram of the electronic device provided in an embodiment of the present application in an unfolded state.

[0081] In one or more embodiments, the present application provides an electronic device, which may be a foldable electronic device. The electronic device includes a housing and a hinge mechanism 100. The housing includes two sub-housings, which are rotatably connected. The rotatable connection enables the electronic device to transition between a folded state and an unfolded state. For ease of description, the two sub-housings are referred to as a first sub-housing 301 and a second sub-housing 302. The first sub-housing 301 and the second sub-housing 302 are respectively connected to the hinge mechanism 100, and the first sub-housing 301 and the second sub-housing 302 are able to rotate relative to each other via the hinge mechanism 100. Exemplarily, the electronic device may be a mobile phone, a tablet computer, a notebook, or an e-reader. Foldable electronic devices are not limited to those with a foldable display screen 200, such as mobile phones. They may also include those with a display screen 200 that can be folded or unfolded between a keyboard and a keyboard, such as laptops. The hinge mechanism 100 may include a base, a swing arm, and a connector. The swing arm is rotatably connected to the base, the swing arm is slidably or rotatably connected to the connector, and the connector is fixedly connected to the sub-housing. Of course, the connector may also be an integral structure with the sub-housing.

[0082] It can be understood that in some cases, the two sub-shells can also be called the main frame and the sub-frame respectively; in addition, in some other possible embodiments, the shell is not limited to including only two sub-shells, but can also include three sub-shells or four sub-shells, etc. When multiple sub-shells are provided, the multiple sub-shells are arranged in sequence along a direction, and the adjacent two sub-shells are rotatably connected.

[0083] In the embodiment of the present application, taking the electronic device as a mobile phone as an example, the electronic device further includes a display screen 200 , which may be a flexible display screen 200 , and the display screen 200 is connected to the first sub-shell 301 and the second sub-shell 302 , respectively.

[0084] For ease of description, as shown in the figure, the width direction of the foldable electronic device can be defined as the BB direction, the length direction of the foldable electronic device can be defined as the AA direction, and the thickness direction of the foldable electronic device can be defined as the CC direction. The AA direction, the BB direction, and the CC direction are mutually perpendicular to each other to form a rectangular coordinate system. The axial direction of the hinge mechanism 100 is parallel to the AA direction.

[0085] Figure 1 The foldable electronic device is shown in a folded state. Figure 2 The foldable electronic device is shown in a semi-expanded state. Figure 3 The foldable electronic device is shown in an unfolded state. Figure 2 The unfolding angle α of the foldable electronic device shown is 90°. Figure 3The unfolding angle β of the foldable electronic device is shown to be 180°. The state of the electronic device is the same as the state of the hinge mechanism 100. That is, when the foldable electronic device is folded, the hinge mechanism 100 is also folded; when the foldable electronic device is semi-expanded, the hinge mechanism 100 is also semi-expanded; and when the foldable electronic device is unfolded, the hinge mechanism 100 is also unfolded.

[0086] It should be noted that the angles described in the examples in this application are all allowed to have slight deviations. For example, Figure 2 The unfolding angle α of the foldable electronic device shown is 90°, which means that α can be 90° or approximately 90°, such as 80°, 85°, 95° or 100°. Figure 3 The unfolding angle β of the foldable electronic device shown is 180°, which means that β can be 180° or approximately 180°, such as 170°, 175°, 185°, and 190°. The angles described below as examples can be understood in the same way.

[0087] Please combine Figure 1 and Figure 2 As shown, the first sub-shell 301 and the second sub-shell 302 are respectively mounted on either side of the hinge mechanism 100. The display screen 200 includes a first portion 201, a second portion 202, and a foldable portion 203. The foldable portion 203 is located between the first portion 201 and the second portion 202 and can bend about an axis parallel to the AA direction. In this embodiment, the display screen 200 is a flexible display screen, such as an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MLED) display screen, a quantum dot light-emitting diode (QLED) display screen, and the like.

[0088] The first sub-housing 301 and the second sub-housing 302 move relatively close together, driving the display 200 to fold, thereby folding the foldable electronic device. When the foldable electronic device is in the folded state, the foldable portion 203 of the display 200 bends, and the first portion 201 and the second portion 202 are positioned relative to each other. At this point, the display 200 is positioned between the first sub-housing 301 and the second sub-housing 302, significantly reducing the risk of damage to the display 200 and effectively protecting it.

[0089] Please also refer to Figure 2 The first sub-housing 301 and the second sub-housing 302 rotate relative to each other via the hinge mechanism 100. As the first sub-housing 301 and the second sub-housing 302 move away from each other, the display screen 200 unfolds, allowing the foldable electronic device to unfold to a semi-expanded state. When the foldable electronic device is in the semi-expanded state, the first sub-housing 301 and the second sub-housing 302 unfold to an angle α, and the first portion 201 and the second portion 202 unfold relative to each other, driving the foldable portion 203 to unfold. At this point, the angle between the first portion 201 and the second portion 202 is α.

[0090] Please combine Figure 2 and Figure 3 As shown, the first sub-housing 301 and the second sub-housing 302 rotate relative to each other via the hinge mechanism 100. As the first sub-housing 301 and the second sub-housing 302 move away from each other, the display screen 200 further unfolds until the foldable electronic device is flattened. The hinge mechanism 100 may include a damping mechanism to provide a smooth opening and closing feel and maintain a stable state during rotation.

[0091] When the electronic device is flattened, the angle between the first sub-housing 301 and the second sub-housing 302 is β. The foldable portion 203 is unfolded, and the first portion 201 and the second portion 202 are relatively unfolded. At this point, the angles between the first portion 201, the second portion 202, and the foldable portion 203 are all β, and the display screen 200 has a large display area, enabling large-screen display for the foldable electronic device and improving the user experience.

[0092] It should be noted that angles α and β are both the angles between the first sub-case 301 and the second sub-case 302. These angles are used to distinguish the angles between the first sub-case 301 and the second sub-case 302 in different states of the foldable electronic device. Angle α refers to the angle between the first sub-case 301 and the second sub-case 302 when the foldable electronic device is in the semi-expanded state, while angle β refers to the angle between the first sub-case 301 and the second sub-case 302 when the foldable electronic device is in the expanded state.

[0093] In the examples of this application, see Figures 1 to 3As shown, the mobile phone can be an inward folding screen mobile phone. After the inward folding screen mobile phone is folded, the display screen 200 is hidden, and the first sub-shell 301 and the second sub-shell 302 are exposed, so that the display screen 200 is protected by the first sub-shell 301 and the second sub-shell 302. Figure 4 This is a structural diagram of another electronic device provided in an embodiment of the present application in a semi-expanded state; see Figure 4 As shown, when the electronic device is a mobile phone, the mobile phone can also be an external folding screen mobile phone. After the external folding screen mobile phone is folded, the first sub-shell 301 and the second sub-shell 302 are opposite to each other, so that the display screen 200 is exposed.

[0094] Figure 5 It is a structural diagram of a foldable mobile phone in the related art; see Figure 5 As shown, the foldable mobile phone includes a main frame 10 and a sub-frame 11, which are rotatably connected to each other. A first mounting area 12 for mounting a mainboard, a second mounting area 13 for mounting, and a third mounting area 14 for mounting a small board are respectively provided on the main frame 10 and the sub-frame 11. The main frame 10 and the sub-frame 11 cooperate so that the foldable mobile phone has a folded state and an unfolded state, and the magnets 15 respectively installed on the main frame 10 and the sub-frame 11 attract each other to assist the foldable mobile phone in maintaining the folded state; however, the magnet 15 will occupy a certain area and volume, and in some cases, it will also conflict with other components of the mobile phone, such as the stacking of speakers.

[0095] In order to solve the problems in the related art, the electronic device provided in the embodiment of the present application can reduce the number of required magnets and will not cause stacking conflicts with the installation of speakers.

[0096] Figure 6 This is a schematic diagram of the structure of the electronic device in the embodiment of the present application, see Figure 6As shown, in some embodiments, the electronic device further includes a first magnetic component 102 and a speaker 101; the first magnetic components 102 are respectively installed on the two sub-shells, and the first magnetic components 102 on the two sub-shells cooperate with each other; the speaker 101 includes a core 103, and the core 103 includes a first magnet 104; wherein, at least one of the two sub-shells is installed with the speaker 101, so that the first magnetic component 102 on the sub-shell on which the speaker 101 is installed is used to form the first magnet 104; when the electronic device is in a folded state, the first magnetic components 102 on the two sub-shells attract each other to keep the electronic device in a folded state. In this way, at least one magnet is replaced by the first magnet 104 in the speaker 101, that is, the magnet that provides the suction force for the electronic device to be in the closed state (i.e., the folded state) is shared with the first magnet 104 in the speaker 101, so that the suction force for the two sub-shells to maintain the closed state is provided by the first magnet 104 inside the speaker 101; compared with the related art, the present application can reduce the number of magnets required, which is conducive to reducing the weight of the electronic device, reducing the manufacturing cost, and saving space. The first magnet 104 used for the speaker 101 is combined with the first magnetic attraction member 102 for maintaining the folded state, which also makes the design of the electronic device simpler, and can better control and balance the effect of the magnetic field, making the folded state more firm and stable. In addition, since the installation of the speaker 101 will not cause stacking conflicts, the structure of the speaker 101 itself can be optimized to improve the audio effect of the speaker 101 and enhance the sound quality performance of the electronic device.

[0097] For example, see Figure 6 As shown, first magnetic members 102 are mounted on the first sub-shell and the second sub-shell, respectively. The two first magnetic members 102 are positioned correspondingly on the two sub-shells, and when the electronic device is in the folded state, the two corresponding first magnetic members 102 are attracted to each other. Both the first magnetic member 102 and the first magnet 104 are magnets. The first sub-shell is equipped with a first magnetic component 102, and the second sub-shell is equipped with a speaker 101, that is, the speaker 101 of the second sub-shell is used in conjunction with the first magnetic component 102 on the first sub-shell, and the first magnetic component 102 on the second sub-shell can be a part of the first magnet 104, that is, the first magnet 104 can include the first magnetic component 102, so that the first magnetic component 102 on the second sub-shell equipped with the speaker 101 is a part of the speaker 101, and is located in the speaker 101. In this way, the second sub-shell equipped with the speaker 101 in this application will not provide a first magnetic component 102 on the outside of the speaker 101 to cooperate with the first magnetic component 102 on the first sub-shell, thereby reducing the number of magnets, and the installation of the speaker 101 will not cause stacking conflicts.

[0098] In some embodiments, see Figure 6As shown, the electronic device also includes a second magnetic component 105, and the second magnetic components 105 are respectively installed on the two sub-shells, that is, the second magnetic components 105 are respectively installed on the first sub-shell and the second sub-shell, and the second magnetic components 105 on the two sub-shells cooperate with each other; when the electronic device is in a folded state, the second magnetic components 105 on the two sub-shells attract each other, so the use of the second magnetic component 105 can further ensure that the electronic device remains in a closed state.

[0099] For example, see Figure 6 As shown, the first magnetic member 102 and the second magnetic member 105 are spaced apart; the second magnetic member 105 is a magnet; the first magnetic member 102 is close to the top of the sub-shell, and the second magnetic member 105 is close to the bottom of the sub-shell; the direction from the top to the bottom of the sub-shell is parallel to the length of the electronic device. The first sub-shell has a first magnetic member 102 and a second magnetic member 105, and the second sub-shell has a speaker 101 and a second magnetic member 105. It is understood that in some other possible embodiments, the speaker 101 can also be located near the bottom of the sub-shell.

[0100] See also Figure 6 As shown, in some embodiments, the sub-shell has a first side 106 and a second side 107 relative to each other, that is, the first sub-shell and the second sub-shell both have a first side 106 and a second side 107 relative to each other; the first side 106 is connected to the hinge mechanism 100; the direction from the first side 106 to the second side 107 is parallel to the width direction of the sub-shell, that is, parallel to the BB direction; the sub-shell includes a first division 108 and a second division 109 connected to the first division 108, and the dividing line between the first division 108 and the second division 109 is the center line L1 of the sub-shell in its own width direction. The first division 108 is connected to the hinge mechanism, so that the hinge mechanism is used to facilitate relative rotation between the two sub-shells, thereby realizing the folding and unfolding of the electronic device. Exemplarily, the first side 106 is located on the first division 108, and the second side 107 is located on the second division 109; the first division 108 and the second division 109 are an integral structure, and the widths of the first division 108 and the second division 109 in the width direction of the sub-shell are equal, so that the dividing line between the first division 108 and the second division 109 is the center line of the sub-shell in its own width direction.

[0101] In some embodiments, the center line L2 of the core 103 in the width direction of the sub-shell is located on the second sub-section 109; or, the center line L2 of the core 103 in the width direction of the sub-shell coincides with the center line L1 of the sub-shell in its own width direction. This allows the first magnet 104 of the core 103 to be away from the rotating shaft mechanism in the width direction of the sub-shell, so that the magnetic force of the first magnet 104 can provide a large torque to ensure that the electronic device remains in a closed state. For example, see Figure 6 As shown, the core 103 of the loudspeaker 101 is in a regular shape, which can be roughly in the shape of a rectangular parallelepiped or a cylindrical shape; the midpoint of the width of the core 103 is located on the center line L2 of the core 103 in the width direction of the sub-shell, the midpoint of the width of the sub-shell is located on the center line L1 of the sub-shell in its own width direction, and the center line L2 of the core 103 in the width direction of the sub-shell is located on the second section 109, which can provide greater torque; Figure 6 In the example, taking the speaker 101 being located on the second sub-housing 302 , the center line L2 of the core 103 of the speaker 101 in the width direction on the second sub-housing 302 is located on the second sub-portion 109 of the second sub-housing 302 .

[0102] It should be noted that in some other possible embodiments, the center line L2 of the core 103 in the width direction of the sub-shell can also be located on the first sub-portion 108, and the distance between the center line L2 of the core 103 in the width direction of the sub-shell and the center line of the sub-shell in its own width direction is not greater than a first preset value. In this way, when the core 103 is away from the second side 107 and close to the first side 106, the distance between the center line L2 of the core 103 in the width direction of the sub-shell and the center line L1 of the sub-shell in its own width direction is limited, which can also ensure that the electronic device remains in a closed state. Selecting an appropriate range for the first preset value can also ensure that the electronic device remains in a closed state. For example, the first preset value is greater than zero and is not greater than 11 mm. The first preset value can be 2 mm, 6 mm, 8 mm, or 10 mm.

[0103] Figure 7 is a schematic diagram of a partial structure of an electronic device in an embodiment of the present application; Figure 8 It is along Figure 7 Cross-sectional view of the middle DD line; combined Figure 7 and Figure 8 As shown, in some embodiments, the speaker 101 further includes a housing 110, the housing 110 having a housing cavity, the core 103 being installed in the housing cavity, and the housing cavity being divided into a front cavity 111 and a rear cavity 112 by the core 103; the front cavity 111 is connected to a sound outlet 113 provided on the sub-housing, and the airflow generated by the core 103 flows through the front cavity 111 to the sound outlet 113 (see Figure 4The inner core 103 has a front cavity surface 123 and a rear cavity surface 122 relative to each other, the front cavity surface 123 faces the front cavity 111, and the rear cavity surface 122 faces the rear cavity 112, and the distance between the front cavity surface 123 and the inner surface of the display screen 200 can be more than 0.7 mm. The sub-shell of the electronic device also has relative inner side surfaces 114 and outer side surfaces 115. When the electronic device is in a folded state, the inner side surface 114 is located between the two outer side surfaces 115, that is, when the electronic device is in a folded state, the outer side surface 115 faces the outside. The electronic device also includes a back plate 124 and a battery (not shown), and a battery is mounted on at least one sub-shell. The back plate 124 is fixedly connected to the sub-shell so that the back plate 124 can protect the battery. The display screen and the back panel 124 can be installed in such a way that the display screen is installed on the inner side surface 114 and the back panel 124 is installed on the outer side surface 115; or, the display screen is installed on the outer side surface 115 and the back panel 124 is installed on the inner side surface 114. In this way, the electronic device of the present application can be applied to both inward-folding electronic devices and outward-folding electronic devices, thereby improving the application scenarios of the electronic devices in the present application. For inward-folding electronic devices, when the inward-folding electronic device is in a folded state, the display screen is hidden and the back panel 124 is exposed; for outward-folding electronic devices, when the outward-folding electronic device is in a folded state, the back panel 124 is hidden and the display screen is exposed. For example, see Figure 8 As shown, the front cavity 111 of the speaker 101 faces the display screen, the front cavity surface 123 faces the front cavity 111, the rear cavity surface 122 faces the rear cavity 112, and the rear cavity surface 122 also faces the back panel 124. The distance between the front cavity surface 123 and the inner surface of the screen can be greater than 0.7 mm.

[0104] It should be noted that, in some other possible implementations, the back panel 124 may be replaced by an additional screen, or a portion of the back panel 124 may be hollowed out and an additional screen may be provided.

[0105] Figure 9 is a structural diagram of the speaker 101 in an embodiment of the present application; Figure 10 This is a schematic diagram of the structure of the first magnet 104 and the first magnetic yoke 116 in the embodiment of the present application; Figure 9 and Figure 10As shown, in some embodiments, the core 103 further includes a first magnetic yoke 116 and a diaphragm 117; the first magnetic yoke 116 is in a sheet shape; the first magnetic yoke 116 is arranged on one side of the first magnet 104, and the diaphragm 117 is located on the other side opposite to the first magnet 104, and the diaphragm 117 faces the front cavity 111, so that the diaphragm 117 can vibrate in the front cavity 111, thereby causing the speaker 101 to produce sound; one side of the first magnetic yoke 116 faces the first magnet 104, and the other side opposite to the first magnetic yoke 116 faces the rear cavity 112. In order to facilitate the distinction between the two sides of the first magnetic yoke 116, the two sides of the first magnetic yoke 116 are respectively referred to as the first side 118 and the second side 119. The first magnet 104 is in contact with the first side 118, and the second side 119 is away from the first magnet 104, and the second side 119 faces the rear cavity 112. The front cavity surface 123 of the core 103 can be the outer surface of the diaphragm 117, which faces the front cavity 111. The back cavity surface 122 of the core 103 can be the second side surface 119 of the first magnetic yoke 116, that is, the other side opposite to the first magnetic yoke 116. The first magnet 104 includes multiple sub-magnets 120. Among the multiple sub-magnets 120 assembled together, the remaining sub-magnets 120 are distributed circumferentially around one of the sub-magnets 120. For example, Figure 11 As shown, the sub-magnets 120 can be in a rectangular parallelepiped shape, which can be suitable for the rectangular parallelepiped core 103; the number of sub-magnets 120 is 5. It is understandable that the number of sub-magnets 120 is not limited to 5, and can also be 6, 7, or 8 as needed.

[0106] Figure 11 It is a structural diagram of another perspective of the cooperation between the first magnet 104 and the first magnetic yoke 116 in the embodiment of the present application. A first through hole 121 is provided on the first magnetic yoke 116. The opening of the first through hole 121 is arranged relative to the gap between the two sub-magnets 120 that are assembled together. In this way, after the first magnet 104 of the speaker 101 replaces the magnet that provides the suction force of the electronic device in the closed state (i.e., the folded state) in the related art, the first through hole 121 is used to make part of the magnetic lines of force of the sub-magnet 120 of the first magnet 104 inside the speaker 101 no longer bound by the first magnetic yoke 116. This part of the magnetic lines of force can leak to the outside of the first magnetic yoke 116, thereby increasing the magnetic force required for the electronic device to maintain a closed state without affecting the reliability of the speaker 101. For example, in combination with Figure 10 and Figure 11 As shown, the number of first through holes 121 is four; the first through holes 121 can be rectangular through holes. It is understandable that the first through holes 121 can also be circular through holes; the number of first through holes 121 is not limited to four, and can also be set to five, six, seven, or eight as needed.

[0107] Figure 12 This is another structural diagram of the first magnet 104 and the first magnetic yoke 116 in the embodiment of the present application; see Figure 12 As shown, in other embodiments, a first through hole 121 is formed on the first magnetic yoke 116, and the opening of the first through hole 121 is arranged opposite to the surface of the sub-magnet 120. In this way, part of the magnetic force lines of the sub-magnet 120 of the first magnet 104 inside the speaker 101 are no longer constrained by the first magnetic yoke 116, and these part of the magnetic force lines can leak to the outside of the first magnetic yoke 116, thereby increasing the magnetic force required for the electronic device to maintain a closed state without affecting the reliability of the speaker 101. For example, Figure 12 As shown, there is one first through hole 121 located in the middle of the first magnetic yoke 116, with its opening corresponding to the central sub-magnet 120 among the multiple assembled sub-magnets 120. It is understood that the number of first through holes 121 can also be three, five, or other numbers, and the specific number can be determined based on actual conditions, as long as the opening of the first through hole 121 can correspond to the surface of the sub-magnet 120.

[0108] In some embodiments, the distance between the first magnet 104 and the outer side 115 is greater than the distance between the first magnet 104 and the inner side 114, so that the first magnet 104 is closer to the inner side 114, so that the first magnet 104 can provide a larger magnetic force to ensure that the electronic device remains in a closed state. When set up in this way, in order to ensure the magnetic attraction effect between the two sub-shells, it is necessary to design the speaker 101 itself or the installation position and direction of the speaker 101 on the sub-shell to achieve a distance between the first magnet 104 and the outer side 115 greater than the distance between the first magnet 104 and the inner side 114. As for the loudspeaker 101 itself, since the diaphragm 117 of the core 103 has a vibration space, and the diaphragm 117 and the first magnetic yoke 116 are respectively located on two opposite sides of the first magnet 104, that is, the diaphragm 117 and the first magnetic yoke 116 are located on two different sides of the first magnet 104, the distance between the first magnet 104 and the rear cavity surface 122 is smaller than the distance between the first magnet 104 and the front cavity surface 123. In this way, when installing the loudspeaker 101, it is only necessary to make the inner side surface 114 and the rear cavity surface 123 22 and the first magnetic yoke 116 are located on one side of the first magnet 104, and the outer side surface 115, the front cavity surface 123, and the diaphragm 117 are located on the other side opposite to the first magnet 104. In this way, the direction of the inner side surface 114 of the sub-shell on which the speaker 101 is installed is the same as the direction of the rear cavity surface 122 of the speaker 101 on the sub-shell itself, so that after the speaker 101 is installed on the sub-shell, the first magnet 104 is closer to the inner side surface 114, thereby ensuring that the electronic device remains in a closed state.

[0109] Figure 13 is another structural diagram of the electronic device in the embodiment of the present application; see Figure 13 As shown, in other embodiments, speakers 101 are respectively installed on the two sub-shells, that is, the speaker 101 is installed on the first sub-shell, and the speaker 101 is installed on the second sub-shell. The first magnetic member 102 on the first sub-shell is used to form the first magnet 104 of the speaker 101 on the first sub-shell; the first magnetic member 102 on the second sub-shell is used to form the first magnet 104 of the speaker 101 on the second sub-shell. In this way, when speakers 101 need to be installed on both sub-shells, the first magnet 104 of the speaker 101 can replace the original magnet in the related art, thereby reducing the number of magnets required and reducing the weight of the electronic device. For example, as Figure 13 As shown, the speakers 101 on the two sub-shells are close to the top of the sub-shells, and the positions of the speakers 101 on the first sub-shell correspond to the positions of the speakers 101 on the second sub-shell. In this way, when the electronic device is in the folded state, the speakers 101 on the first sub-shell cooperate with the speakers 101 at the corresponding positions on the second sub-shell, and the first magnets 104 in the cores 103 of the two speakers 101 attract each other to maintain the electronic device in a closed state. Figure 13 The electronic device has two correspondingly arranged speakers 101 and two correspondingly arranged second magnetic members 105 .

[0110] It should be noted that, in some other possible implementations, the second magnetic member 105 may not be provided in the electronic device. In the absence of the second magnetic member 105, one speaker 101 and three additional first magnetic members 102 may be provided in the electronic device, wherein one speaker 101 on one sub-shell and one first magnetic member 102 on another sub-shell attract each other, and the other two corresponding first magnetic members 102 on the two sub-shells attract each other; or, two speakers 101 and two additional first magnetic members 102 are provided, and the two speakers 101 on one sub-shell are respectively attracted to the other. The two first magnetic parts 102 on the sub-shell are matched one by one and attract each other; or, three speakers 101 and one additional first magnetic part 102 are set, one of the speakers 101 on one sub-shell and the first magnetic part 102 on another sub-shell are attracted to each other, and the other two corresponding speakers 101 on the two sub-shells are attracted to each other; or, four speakers 101 are set, one speaker 101 on one sub-shell and one speaker 101 on another sub-shell are attracted to each other, and another speaker 101 on one sub-shell and another speaker 101 on another sub-shell are attracted to each other.

[0111] Figure 141 is a schematic diagram of the corresponding relationship between the cores 103 of the two speakers 101 of the electronic device in the folded state in the embodiment of the present application; Figure 13 and Figure 14 As shown, in some embodiments, when the electronic device is in a folded state, the rear cavity surface 122 of the speaker 101 on the first sub-shell and the rear cavity surface 122 of the speaker 101 on the second sub-shell are arranged to face each other, so that the rear cavity surface 122 of the speaker 101 on the sub-shell and the inner side surface 114 are oriented in the same direction, and the front cavity surface 123 of the speaker 101 on the sub-shell and the outer side surface 115 are oriented in the same direction. After the speaker 101 is installed on the sub-shell, the first magnet 104 is closer to the inner side surface 114, thereby ensuring that the electronic device remains in a closed state.

[0112] It should be noted that, in some other possible embodiments, the speaker 101 can be installed so that the front cavity surface 123 of the speaker 101 on the two sub-shells are oriented in the same direction as the inner side surface 114 of their respective corresponding sub-shells, or, in the two sub-shells, the front cavity surface 123 of the speaker 101 on one of the sub-shells is oriented in the same direction as the outer side surface 115 of its own sub-shell, and the front cavity surface 123 of the speaker 101 on the other sub-shell is oriented in the same direction as the inner side surface 114 of its own sub-shell.

[0113] In some embodiments, the orthographic projection of the core 103 of the loudspeaker 101 on the first sub-shell in the first plane and the orthographic projection of the core 103 of the loudspeaker 101 on the second sub-shell in the first plane have an overlapping area, and the ratio T of the area of ​​the overlapping area to the area of ​​the orthographic projection of the core 103 of the loudspeaker 101 in the first plane satisfies the following relationship: 0.2≤T≤1; the first plane is perpendicular to the thickness direction of the electronic device, so that a complete overlap or partial overlap is adopted to ensure the magnetic force of attraction between the two first magnets 104 and to ensure that the electronic device remains in a closed state. For example, the ratio T can be 0.2, 0.3, 0.5 or 1, that is, the orthographic projections of the cores 103 on the two sub-shells in the first plane can be partially overlapped or completely overlapped. Figure 14 As shown, the orthographic projections of the cores 103 of the speakers 101 on the two sub-shells in the first plane partially overlap. Exemplarily, the orthographic projection of the core 103 of the speaker 101 on the first sub-shell 301 in the first plane completely overlaps with the orthographic projection of the core 103 of the speaker on the second sub-shell 302 in the first plane; the display screen 200 is located on the outer side surface 115 of the sub-shell, that is, the display screens on the first sub-shell 301 and the second sub-shell 302 are both located on the outer side surface 115, and the back panel 124 is located on the inner side surface 114 of the second sub-shell 302, that is, the back panels 124 on the first sub-shell 301 and the second sub-shell 302 are both located on the inner side surface 114.

[0114] It should be noted that the first plane does not refer to a single plane, and it can be any plane that is parallel to and perpendicular to the thickness direction of the electronic device.

[0115] Figure 15 1 is a schematic diagram of the corresponding relationship between the cores 103 of the two speakers 101 of another electronic device in a folded state in an embodiment of the present application; see Figure 15 As shown, the orthographic projections of the cores 103 of the speakers 101 on the two sub-shells in the first plane completely overlap. Exemplarily, the orthographic projection of the core 103 of the speaker 101 on the first sub-shell 301 in the first plane completely overlaps with the orthographic projection of the core 103 of the speaker on the second sub-shell 302 in the first plane, which can better ensure that the electronic device remains in a closed state; the display screen 200 is located on the outer side surface 115 of the sub-shell, that is, the display screens on the first sub-shell 301 and the second sub-shell 302 are both located on the outer side surface 115, and the back panel 124 is located on the inner side surface 114 of the second sub-shell 302, that is, the back panels 124 on the first sub-shell 301 and the second sub-shell 302 are both located on the inner side surface 114.

[0116] Figure 16 1 is a schematic diagram of the corresponding relationship between the cores 103 of the two speakers 101 of another electronic device in a folded state according to an embodiment of the present application; Figure 16 As shown, the orthographic projections of the cores 103 of the speakers 101 on the two sub-shells in the first plane completely overlap. For example, the orthographic projection of the core 103 of the speaker 101 on the first sub-shell 301 in the first plane completely overlaps with the orthographic projection of the core 103 of the speaker on the second sub-shell 302 in the first plane, which can better ensure that the electronic device remains in a closed state; the display screen 200 is located on the inner side 114 of the sub-shell, that is, the display screens 200 on the first sub-shell 301 and the second sub-shell 302 are both located on the inner side 114, and the back panel 124 is located on the outer side 115 of the second sub-shell 302, that is, the back panels 124 on the first sub-shell 301 and the second sub-shell 302 are both located on the outer side 115.

[0117] It should be noted that for Figure 14 、 Figure 15 and Figure 16 , the first magnet 104 in the core 103 and the polarity of the first magnet 104 are also shown to illustrate that when the electronic device is in the folded state, the first magnets 104 on the two sub-shells can attract each other.

[0118] Figure 17 : is a magnetic simulation diagram of the core 103 of the loudspeaker 101 at corresponding positions on two sub-shells in the embodiment of the present application. Figure 17 Different colors represent the distribution of magnetic field at different locations; see Figure 17As shown, in some embodiments, when the electronic device is in the folded state and the distance between the two cores 103 is 1.23 mm, the magnetic force between the first magnets 104 of the two cores 103 is 1.67 N. Furthermore, simulations have shown that when the first through hole 121 is provided in the first magnetic yoke 116 and the opening of the first through hole 121 is positioned opposite the surface of the sub-magnet 120 located in the middle, the magnetic force increases, reaching a magnetic force of 2.6 N between the first magnets 104 of the two cores 103, which can better ensure that the electronic device remains in the closed state.
