[0023] The technical solutions in the embodiments of the present application will be described clearly below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by “first”, “second”, etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, “and / or” in the specification and claims indicates at least one of the connected objects, and the character “ / ” generally indicates that the front and rear associated objects are in an “or” relationship.
[0025] The foldable screen device, the control method and the device of the foldable screen device provided by the embodiments of the present application will be described in detail below in conjunction with the drawings and specific embodiments and application scenarios.
[0026] Figure 1 a structural schematic diagram of a foldable electronic device is shown, such as Figure 1As shown, the foldable electronic device 110 disclosed in the embodiments of the present application can include a first shell 111 and a second shell 112 rotationally connected with the first shell 111.
[0027] In the embodiments of the present application, as shown in Figure 1 In the embodiments of the present application, a first loudspeaker 131 is arranged on the first shell 111, and an auxiliary magnetic member 132 is arranged on the second shell 112. When the first shell 111 and the second shell 112 are in the buckling state, the first loudspeaker 131 and the auxiliary magnetic member 132 are opposite to each other. During the process of separating the first shell 111 and the second shell 112, for example, during the process of separating the first shell 111 and the second shell 112 after receiving an operation command for unfolding the first shell 111 and the second shell 112, the first loudspeaker 131 and the auxiliary magnetic member 132 repel each other or the attractive force between the first loudspeaker 131 and the auxiliary magnetic member 132 decreases.
[0028] In the foldable electronic device provided by the embodiments of the present application, the first shell 111 and the second shell 112 are rotationally connected, for example, the connecting part 120 of the first shell 111 and the second shell 112 can be a rotating shaft. When the first shell 111 and the second shell 112 are in the buckling state, the first loudspeaker 131 arranged on the first shell 111 is opposite to the auxiliary magnetic member 132 arranged on the second shell 112, and the first loudspeaker 131 and the auxiliary magnetic member 132 are attracted to each other, so that the first shell 111 and the second shell 112 are buckled. During the process of separating the first shell 111 and the second shell 112, that is, when the buckling between the first shell 111 and the second shell 112 is opened, the repulsive force between the first loudspeaker 131 and the auxiliary magnetic member 132 can be generated, so as to weaken or offset the attractive force between the first loudspeaker 131 and the auxiliary magnetic member 132, so that the first loudspeaker 131 and the auxiliary magnetic member 132 repel each other or the attractive force between the first loudspeaker 131 and the auxiliary magnetic member 132 decreases, to facilitate unfolding the first shell 111 and the second shell 112.
[0029] In the embodiments of the present application, the first loudspeaker 131 can be arranged on the first shell 111 away from the connecting part 120 of the first shell 111 and the second shell 112, for example, in Figure 1 In the embodiments of the present application, the first loudspeaker 131 is arranged on the edge of the first shell 111 opposite to the connecting part.
[0030] In one possible implementation manner of the embodiments of the present application, as shown in Figure 1As shown, the first speaker 131 is provided with a speaker coil 1311. Therefore, in one possible implementation, when the speaker coil 1311 is connected with a first current, repulsive force can be generated between the speaker coil 1311 and the auxiliary magnetic member 132, so that the speaker coil 1311 repels the auxiliary magnetic member 132. According to Ampere's law, when the speaker coil 1311 is connected with a current, an electromagnetic field is generated. By controlling the direction of the first current, the direction of the electromagnetic field can be made the same as the direction of the magnetic field generated by the end of the auxiliary magnetic member 132 close to the first speaker 131, so that the speaker coil 1311 repels the auxiliary magnetic member 132. Thus, the attractive force between the first speaker 131 and the auxiliary magnetic member 132 can be reduced, and the user can easily open the buckled first shell 111 and second shell 112.
[0031] In one possible implementation, as shown in Figure 2 , Figure 3a and Figure 3b , the first speaker 131 can include a permanent magnet 1312 and a first magnetic shielding sheet 141 provided on the side of the permanent magnet 1312. The first magnetic shielding sheet 141 is provided with a conductive path 151, and the conductive path is connected with a second current during the separation of the first shell 111 and the second shell 112. The first magnetic shielding sheet 141 generates repulsive force that repels the auxiliary magnetic member 132. In this possible implementation, when the first speaker 131 is normally working, the magnetic shielding effect of the first magnetic shielding sheet 141 can reduce the magnetic force influence of the permanent magnet 1312 in the first speaker on other components inside or outside the electronic device. During the separation of the first shell 111 and the second shell 112 of the electronic device 110, the conductive path 151 provided on the first magnetic shielding sheet 141 is connected with a second current, so that the conductive path can generate a spiral magnetic field. At the position of the auxiliary magnetic member 132 close to the first speaker 131, the spiral magnetic field is opposite to the magnetic field generated by the permanent magnet 1312 in the first speaker 131, so that the first magnetic shielding sheet 141 repels the auxiliary magnetic member 132, thereby weakening or canceling the attractive force of the permanent magnet 1312 on the auxiliary magnetic member 132.
[0032] In the embodiments of the present application, the magnetic shielding sheet is an object that can change the direction of the magnetic force line of the magnetic field. It has a very strong effect of attracting the magnetic field, for example, if a magnetic shielding sheet is placed beside a magnet, the magnetic force line of the magnet will be attracted to the magnetic shielding sheet, and the magnetic field strength outside the magnetic shielding sheet is reduced.
[0033] In the embodiments of the present application, the magnetic isolation sheet can be a soft magnetic material, i.e. a material that can attract magnetic lines of force in a magnetic field and weaken the magnetic field. In addition, the magnetic isolation sheet in the embodiments of the present application can be a conductor, i.e. the first magnetic isolation sheet 141 itself can form a conductive path, and the direction of the second current passing through the conductive path can be parallel to the circumference of the permanent magnet 1312, so as to generate a magnetic field opposite to the permanent magnet 1312 at the position of the permanent magnet 1312. For example, the first magnetic isolation sheet 141 can be a steel sheet.
[0034] In a possible implementation, the first magnetic isolation sheet 141 can be multiple, such as Figure 3a As shown in FIG. 1, the multiple first magnetic isolation sheets 141 are arranged around the permanent magnet 1312. The multiple first magnetic isolation sheets 141 are connected by the insulating material 161. The two ends of the conductive path 151 of each first magnetic isolation sheet 141 are provided with the first electrode 1411 and the second electrode 1412. The multiple conductive paths 151 are arranged along the circumference of the permanent magnet 1312. That is, in this possible implementation, the multiple first magnetic isolation sheets 141 are arranged around the permanent magnet 1312, so as to reduce the space magnetic field strength around the permanent magnet 1312. When the second current is passed through the conductive path 151 on the multiple first magnetic isolation sheets 141, a magnetic field opposite to the permanent magnet 1312 can be generated. For example, assuming that the magnetic field direction of the lower end surface of the permanent magnet 1312 is upward, as shown in FIG. 1, the second current shown in FIG. 1 can be passed through the conductive path of the multiple first magnetic isolation sheets 141, so as to generate a downward magnetic field, so that the first magnetic isolation sheet 141 repels the auxiliary magnetic member 132, and further assists in unfolding the first shell 111 and the second shell 112. Figure 3a Figure 3b As shown in FIG. 1, the multiple first magnetic isolation sheets 141 are arranged around the permanent magnet 1312. The multiple first magnetic isolation sheets 141 are connected by the insulating material 161. The two ends of the conductive path 151 of each first magnetic isolation sheet 141 are provided with the first electrode 1411 and the second electrode 1412. The multiple conductive paths 151 are arranged along the circumference of the permanent magnet 1312. That is, in this possible implementation, the multiple first magnetic isolation sheets 141 are arranged around the permanent magnet 1312, so as to reduce the space magnetic field strength around the permanent magnet 1312. When the second current is passed through the conductive path 151 on the multiple first magnetic isolation sheets 141, a magnetic field opposite to the permanent magnet 1312 can be generated. For example, assuming that the magnetic field direction of the lower end surface of the permanent magnet 1312 is upward, as shown in FIG. 1, the second current shown in FIG. 1 can be passed through the conductive path of the multiple first magnetic isolation sheets 141, so as to generate a downward magnetic field, so that the first magnetic isolation sheet 141 repels the auxiliary magnetic member 132, and further assists in unfolding the first shell 111 and the second shell 112.
[0035] In a possible implementation, as shown in FIG. 1, any two adjacent first magnetic isolation sheets 141 can be bonded by the insulating material 161, which can be plastic or other materials, and the embodiments of the present application do not make specific limitations thereon. The insulating material can prevent current from interfering with other parts when each first magnetic isolation sheet 141 is energized. Figure 3a
[0036] In a possible implementation, as shown in FIG. 1, any two adjacent first magnetic isolation sheets 141 can be bonded by the insulating material 161, which can be plastic or other materials, and the embodiments of the present application do not make specific limitations thereon. The insulating material can prevent current from interfering with other parts when each first magnetic isolation sheet 141 is energized. Figure 4 As shown, the first speaker 131 can include a permanent magnet 1312 and a second magnetic isolation sheet 142 disposed on the target side of the permanent magnet 1312, and the second magnetic isolation sheet 142 is provided with an auxiliary coil 1421, and the auxiliary coil 1421 is connected to a third current in the process of separating the first shell 111 and the second shell 112, and the magnetic field generated by the auxiliary coil 1421 is in the same direction as the magnetic field generated by the permanent magnet 1312 at the end of the auxiliary magnetic member 132 close to the first speaker 131, so that the auxiliary coil 1421 and the auxiliary magnetic member 132 repel each other. Wherein, in the case that the first shell 111 and the second shell 112 are in the buckling state, the target side is the side of the first speaker 131 away from the second shell 112. That is, the second magnetic isolation sheet 142 is disposed on the side close to the outer surface of the first shell 111. When the first speaker 131 is working normally, the magnetic isolation effect of the second magnetic isolation sheet 142 can reduce the magnetic force generated by the permanent magnet 1312 in the first speaker 131 on other components; when the auxiliary coil 1421 provided on the second magnetic isolation sheet 142 is connected to the third current in the process of separating the first shell 111 and the second shell 112 of the electronic device 110, the auxiliary coil 1421 can generate a magnetic field, and at the end of the auxiliary magnetic member 132 close to the first speaker 131, the magnetic field is opposite to the magnetic field generated by the permanent magnet 1312 in the first speaker 131, so that the second magnetic isolation sheet 142 and the auxiliary magnetic member 132 repel each other, thereby weakening or canceling the attractive force generated by the permanent magnet 1312 on the auxiliary magnetic member 132. For example, assuming that in the Figure 4 , the magnetic field direction of the permanent magnet 1312 is upward, then the third current as shown in Figure 4 can be conducted to the auxiliary coil 1421 of the second magnetic isolation sheet 142, thereby generating a downward magnetic field (as shown by the arrow in Figure 4 ), that is, repelling the auxiliary magnetic member 132, and then assisting in unfolding the first shell 111 and the second shell 112.
[0037] In one possible implementation of the embodiment of the present application, a plurality of first magnetic isolation sheets 141 and second magnetic isolation sheets 142 can be disposed on the first speaker 131 at the same time. As shown in Figure 5As shown, a plurality of the first magnetic isolation sheets 141 are arranged around the permanent magnet 1312 to form a cavity 171. The permanent magnet 1312 is arranged in the cavity 171, and the second magnetic isolation sheet 142 is arranged on one end face of the cavity 171. In the case where the first shell 111 and the second shell 112 are in the buckled state, the second magnetic isolation sheet 142 is located on the side of the cavity away from the second shell 112. The second magnetic isolation sheet 142 is provided with an auxiliary coil 1421. The first magnetic isolation sheet 141 and the second magnetic isolation sheet 142 can wrap the permanent magnet 1312, reduce the magnetic field generated by each face of the permanent magnet 1312 to interfere with other magnetic devices outside, and can reduce the attraction force between the first loudspeaker 131 and the auxiliary magnetic device 132 when the first shell 111 and the second shell 112 are unfolded. For example, if the repulsive force between the magnetic isolation sheet and the auxiliary magnetic device is greater than the attraction force between the permanent magnet of the first loudspeaker 131 and the auxiliary magnetic device 132, the first loudspeaker 131 and the auxiliary magnetic device 132 repel each other, so that a gap appears between the first shell 111 and the second shell 112, and the user can easily separate the first shell 111 and the second shell 112 with one hand.
[0038] In one possible implementation of the embodiments of the present application, as shown in Figure 6 The auxiliary magnetic device 132 can include a second loudspeaker 133, and the structure of the second loudspeaker 133 is the same as that of the first loudspeaker 131. That is, the auxiliary magnetic device 132 can be a loudspeaker with the same structure as the first loudspeaker 131. Through this possible implementation, the buckling between the first shell 111 and the second shell 112 can be achieved by using the attraction force between the permanent magnets in the two loudspeakers arranged opposite to each other in the electronic device, and when the user needs to open the electronic device, that is, the user needs to separate (or also can be called open) the first shell 111 and the second shell 112, by connecting the corresponding current to each loudspeaker, the repulsion between the two loudspeakers arranged opposite to each other or the attraction force between the two loudspeakers is reduced, so that the user can more easily unfold or separate the first shell 111 and the second shell 112.
[0039] In one or more possible implementations, the magnetic properties of the permanent magnet in the first loudspeaker 131 and the permanent magnet in the second loudspeaker 133 are opposite at the opposite ends of the first loudspeaker 131 and the second loudspeaker 133. That is, in the buckled state of the first shell 111 and the second shell 112, the first loudspeaker 131 and the second loudspeaker 133 attract each other.
[0040] In one or more possible implementations, when the first housing 111 and the second housing 112 are separated, a repulsive force is generated between the second speaker 133 and the first speaker 131, so that the second speaker 133 is repelled by the first speaker 131 or the attractive force between the second speaker 133 and the first speaker 131 is reduced. For example, similar to the first speaker 131 described above, a first current can be applied to the speaker coil of the second speaker 133, so that a repulsive force is generated between the speaker coil of the second speaker 133 and the first speaker. Alternatively, a second current can be applied to the first magnetic separation sheet 141 of the second speaker 133, so that a repulsive force is generated between the first magnetic separation sheet 141 of the second speaker 133 and the first speaker. Alternatively, a third current can be applied to the second magnetic separation sheet 142 of the second speaker 133, so that a repulsive force is generated between the second magnetic separation sheet 142 of the second speaker 133 and the first speaker.
[0041] In one possible implementation, as shown in FIG. 1, the first housing 111 is provided with a plurality of first speakers 131, and the plurality of first speakers 131 are uniformly distributed at the edge of the first housing 111 away from the connecting portion 120. The second housing 112 is provided with a plurality of auxiliary magnetic members 132 corresponding to the plurality of first speakers 131, and the plurality of auxiliary magnetic members 132 are uniformly distributed at the edge of the second housing 112 away from the connecting portion 120. The plurality of first speakers 131 and the plurality of auxiliary magnetic members 132 can ensure that the first housing 111 and the second housing 112 are tightly buckled. Figure 6
[0042] In one or more possible implementations, the permanent magnets of two adjacent first speakers 131 on the first housing 111 are magnetically opposite at the end close to each other. Thus, the magnetic field of the entire electronic device can be offset, and the interference with other external magnetic devices can be reduced as much as possible.
[0043] In a possible implementation, the first speaker 131 can include: a permanent magnet 1312, a speaker coil 1311, a plurality of first magnetic isolation sheets 141, and a second magnetic isolation sheet 142; the plurality of first magnetic isolation sheets 141 are arranged around the permanent magnet 1312 to form a cavity 171, and the permanent magnet 1312 is arranged in the cavity 171; the second magnetic isolation sheet 142 is arranged on one end surface of the cavity 171, and in a case where the first shell 111 and the second shell 112 are in a buckled state, the second magnetic isolation sheet 142 is located on a side of the cavity 171 away from the second shell 112; the second magnetic isolation sheet 142 is provided with an auxiliary coil 1421; in a case where the first shell 111 and the second shell 112 are separated, the permanent magnet 1312 and the auxiliary magnetic member 132 have a first attractive force, the speaker coil 1311 and the auxiliary magnetic member 132 have a first repulsive force, the plurality of first magnetic isolation sheets 141 and the auxiliary magnetic member 132 have a second repulsive force, the second magnetic isolation sheet 142 and the auxiliary magnetic member 132 have a third repulsive force, and a resultant force of the first repulsive force, the second repulsive force, and the third repulsive force is greater than the first attractive force.
[0044] In this possible implementation, in a case where the first shell 111 and the second shell 112 are separated, for example, the first shell 111 and the second shell 112 are unfolded in response to an external input, the speaker coil 1311 of the first speaker 131, the plurality of first magnetic isolation sheets 141, and the second magnetic isolation sheet 142 all have repulsive forces with the auxiliary magnetic member 132, the resultant force of the first repulsive force, the second repulsive force, and the third repulsive force is greater than the first attractive force, and thus a gap can be generated between the first shell 111 and the second shell 112, facilitating unfolding of the first shell 111 and the second shell 112.
[0045] In a possible implementation, in a case where the electronic device is in a falling state, the first speaker 131 and the auxiliary magnetic member 132 have a second attractive force; the second attractive force includes the first attractive force, and the second attractive force further includes at least one of:
[0046] a third attractive force between the speaker coil 1311 and the auxiliary magnetic member 132;
[0047] a fourth attractive force between the plurality of first magnetic isolation sheets 141 and the auxiliary magnetic member 132;
[0048] A fifth attractive force between the second magnetic isolation sheet 142 and the auxiliary magnetic member 132.
[0049] For example, a sensor can be arranged in the electronic device, and the motion state of the electronic device can be detected through the sensor. In a case where it is determined that the electronic device is in a falling state according to the motion state detected by the sensor, the speaker coil 1311 can be controlled to be connected to a current in a direction opposite to the first current direction, so that the speaker coil 1311 and the auxiliary magnetic member 132 have a third attractive force of attraction. The plurality of first magnetic isolation sheets 141 can also be controlled to be connected to a current opposite to the second current, so that the plurality of first magnetic isolation sheets 141 and the auxiliary magnetic member 132 have a fourth attractive force of attraction. The second magnetic isolation sheet 142 can also be controlled to be connected to a current in a direction opposite to the third current direction, so that the second magnetic isolation sheet 142 and the auxiliary magnetic member 132 have a fifth attractive force of attraction.
[0050] Through the above possible implementation manners, the heteromagnetic field strength can be recognized and enhanced in advance when the whole machine falls in the buckling state, so that the first shell 111 and the second shell 112 are firmly buckled with strong attractive force, and it is ensured that the electronic device will not fall apart to cause other more serious problems.
[0051] In the above possible implementation manners, the sensor can be a gravity sensor or a gyroscope, and the embodiments of the present application do not make specific limitations thereto.
[0052] The electronic device is taken as an example to describe the electronic device provided by the embodiments of the present application. Figure 6 The electronic device is taken as an example to describe the electronic device provided by the embodiments of the present application.
[0053] In this embodiment, the first speaker 131 and the second speaker 133 are speaker switch modules. As shown in Figure 6 The left and right edges of the electronic device respectively symmetrically place four speaker switch modules, and each speaker switch module can include a speaker structure as shown in Figure 7 The left and right edges of the electronic device respectively symmetrically place four speaker switch modules, and each speaker switch module can include a speaker structure as shown in
[0054] As shown in Figure 7As shown, each speaker contains a speaker coil 1311 made of movable wire, and also contains four auxiliary magnets 13121 and one main magnet 13122. The four auxiliary magnets 13121 and the main magnet 13122 together form a permanent magnet 1312. On one end face of the permanent magnet 1312, the largest main magnet 13122 in the center is N-order, and the auxiliary magnets 13121 around it are S-order. When observed from a position far away from the permanent magnet 1312 and when directly facing the center of the permanent magnet 1312, this end face of the permanent magnet 1312 will show the N-order characteristics of the central magnet. The S-order characteristics of the permanent magnet 1312 can only be observed when it is close to the edge of the permanent magnet 1312.
[0055] In this embodiment, utilizing the inherent characteristics of the speaker, each pair of symmetrically positioned speaker switch modules on the left and right sides of the electronic device (i.e., the aforementioned first housing 111 and second housing 112) are assembled in opposite directions. Thus, in the snap-fit state, regardless of the coil's energization, the two speakers will generate an attractive force due to the opposite magnetic fields of their permanent magnets. Considering that permanent magnets may attract magnetic materials in the external environment (such as iron filings, iron screws, etc.), ... Figure 8 As shown, each speaker can also be equipped with a magnetic shielding sheet to wrap the speaker with magnetic shielding sheets on 5 sides, with only the opening design in the folding direction remaining.
[0056] For example, four first speakers 131 are provided on the first housing, and each first speaker 131 is wrapped with a magnetic shielding sheet group. A magnetic shielding sheet group may include four first magnetic shielding sheets 141 and one second magnetic shielding sheet 142. Four second speakers 133 are provided on the second housing, and each second speaker 133 is wrapped with a magnetic shielding sheet group. A magnetic shielding sheet group may include four first magnetic shielding sheets 141 and one second magnetic shielding sheet 142.
[0057] like Figure 8 As shown, when the whole machine is powered off or in standby mode, the locking effect is achieved by the attraction of the permanent magnets of the first speaker 131 and the second speaker 133. The second magnetic shielding sheet 142 is installed on the outside of the whole machine and the first magnetic shielding sheet 141 is installed on the side to confine the magnetic field of the first speaker 131 and the second speaker 133 to a certain area, so as to avoid the magnetic field influence range being too large and affecting objects outside the whole machine and other magnetically sensitive devices inside the whole machine.
[0058] According to Ampere's law (i.e., the right-hand screw law), a current-carrying conductor generates a magnetic field, and the direction of the magnetic field follows the direction of the right thumb. Based on this law, a magnetic shielding sheet for a loudspeaker (including a first loudspeaker 131 and a second loudspeaker 133) is designed as follows:
[0059] 1. The speaker is surrounded by four first magnetic shielding sheets 141 and one second magnetic shielding sheet 142. Each magnetic shielding sheet is insulated at the seam. That is, the five sides are independently designed and do not affect each other. When a single magnetic shielding sheet is energized, it will not cause current crosstalk to other parts.
[0060] 2. The first magnetic shielding sheet 141 on the side has a straight wire path inside. The left and right sides of the first magnetic shielding sheet 141 are energized electrodes. The electrodes themselves are not polarized; the direction of current flow inside the first magnetic shielding sheet 141 is controlled by changing the polarity of the driving end. Furthermore, these electrodes can be electroplated electrodes to prevent oxidation.
[0061] 3. The second magnetic shielding sheet 142 at the top has a coil made of a wire inside, and the start and end ends of the wire are exposed on the surface as electrodes.
[0062] By applying currents in different directions to the first magnetic shielding sheet 141 and the second magnetic shielding sheet 142, according to Ampere's law, by controlling the magnitude and direction of the current flowing through the first magnetic shielding sheet 141, the second magnetic shielding sheet 142, and the speaker coil 1311 inside the speaker, and superimposing the magnetic field of the permanent magnet of the speaker (including the first speaker 131 and the second speaker 133), the dynamic change of the snapping force of the whole machine can be controlled, so that the first speaker 131 and the second speaker 133 change from opposite poles attracting each other to like poles repelling each other. In this way, the first housing 111 and the second housing 112 can automatically pop open from the snapped state by an angle, so that the user can easily open the machine with one hand.
[0063] The changes in the magnetic field during the process of the first shell 111 and the second shell 112 from the locked state to the unfolded state are explained below.
[0064] When the device is not in operation, the folding screen is snapped shut. After snapping shut, the first speaker 131 and the second speaker 133 corresponding to the first housing 111 and the second housing 112 are nearly in contact. Figure 8 The magnetism of the opposing surfaces of the first speaker 131 and the second speaker 133 is shown, as follows: Figure 8 As shown, since the assembly directions of each pair of first speakers 131 and second speakers 133 are opposite, that is, the first speakers 131 and second speakers 133 are assembled opposite to each other, the total magnetic field of each other after being fastened together will attract each other, thereby locking the whole machine in the fastened state.
[0065] In the buckling state of the first shell 111 and the second shell 112, if the user needs to realize automatic opening of the whole machine, an opening operation command can be input. Specifically, the operation command can be input through an input device of the electronic device, which can be a physical key or a keyboard, for example, a key arranged on the electronic device, or a voice receiving device, for example, a microphone, or a display screen of the electronic device. For example, after buckling, the user can operate on the secondary display screen (for example, the secondary display screen can be arranged on the outer surface of the first shell 111) of the electronic device: first wake up the secondary screen, at this time the secondary screen will appear a slider prompting automatic opening, slide the slider to the end to input the above operation instruction, and trigger the automatic opening operation.
[0066] After receiving the automatic opening operation, the system outputs current inside to the coils inside the first speaker 131 and the second speaker 133 and the external magnetic separation sheet, so that the magnetic field of the eight speakers of the whole machine is changed to the same repulsion, and the specific process is as shown in Figure 9
[0067] As shown in Figure 9 , when the whole machine is in the initial state, that is, the first shell 111 and the second shell 112 are in the buckling state, at this time there is no current, the polarity of the magnetic field of the first speaker 131 on the first shell 111 is S pole, the polarity of the magnetic field of the second speaker 133 on the second shell 112 is N pole, and the whole machine is adsorbed by the attraction of the permanent magnet of the first speaker 131 and the second speaker 133.
[0068] In the case that the speaker coil 1311 of the first speaker 131 and the second speaker 133 is powered, the first speaker 131 on the first shell 111 generates a magnetic field opposite to the magnetic force of its own permanent magnet after being powered, and the overall magnetism of the first speaker 131 on the first shell 111 decreases, and the second speaker 133 on the second shell 112 generates a magnetic field same as the magnetic force of its own permanent magnet after being powered, at this time, the overall magnetism of the second speaker 133 on the second shell 112 is enhanced, at this time, the total magnetic field is basically unchanged, and the total buckling attraction changes little;
[0069] When the first magnetic separation sheet 141 and the second magnetic separation sheet 142 on the first speaker 131 and the second speaker 133 are further powered, the magnetic field generated by the first magnetic separation sheet 141 and the second magnetic separation sheet 142 on the first speaker 131 directly reverses the magnetic field characteristics of the first speaker 131 after weakening the magnetic force. The total magnetic field on the first speaker 131 presents N pole, and the first magnetic separation sheet 141 and the second magnetic separation sheet 142 of the second speaker 133 further enhance the total magnetic field size of the second speaker 133, and the total magnetic field of the second speaker 133 also still presents N pole, so that the state of the same repulsion up and down can be realized, so that the whole machine is opened by the mutual repulsion.
[0070] In the process of opening the whole machine by an angle, since the distance between the first speaker 131 and the second speaker 133 increases, the magnetic field decreases exponentially with the distance, the total attraction force between the first speaker 131 and the second speaker 133 decreases rapidly, and after the attraction force decreases to 0, the whole machine opens a little more due to inertia. After the end of the latching action (i.e. in the whole opening state), the first magnetic shunt 141 and the second magnetic shunt 142 and the speaker coil 1311 stop energizing, at this time the first speaker 131 and the second speaker 133 restore the initial state, present the same size and opposite polarity magnetic field, and since the whole machine has opened a certain angle, the symmetrical first speaker 131 and the second speaker 133 are too far apart, at this time the latching attraction force can be ignored, so the whole machine will not latch back, and the damping in the shaft will make the folding device stop at the angle after automatic opening. The user can easily unfold the whole machine after opening with one hand.

[0073] For example, when the foldable electronic device is in a folded state, i.e. the first housing 111 and the second housing 112 are latched, the user can input the external operation through the power-on key or the power key or the total control key of the electronic device, instructing to open the first housing 111 and the second housing 112, i.e. instructing to separate the first housing 111 and the second housing 112.
