A foldable screen device, a control method of the foldable screen device, and an apparatus provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1 shows a schematic structural diagram of a foldable electronic device, and as shown in fig. 1, a foldable electronic device 110 disclosed in an embodiment of the present application may include: a first housing 111, and a second housing 112 rotatably coupled to the first housing 111.

As shown in fig. 1, in the embodiment of the present application, a first speaker 131 is disposed on the first housing 111; an auxiliary magnetic member 132 is provided on the second housing 112, and when the first housing 111 and the second housing 112 are in a locked state, the first speaker 131 and the auxiliary magnetic member 132 are opposite to each other; in the process of separating the first housing 111 and the second housing 112, for example, in the process of separating the first housing 111 and the second housing 112 of the electronic device 110 upon receiving an operation command to unfold the first housing 111 and the second housing 112, the first speaker 131 and the auxiliary magnetic member 132 repel each other or the attraction force between the first speaker 131 and the auxiliary magnetic member 132 is reduced.

In the foldable electronic device provided in the embodiment of the present application, the first housing 111 is rotatably connected to the second housing 112, for example, the connection portion 120 of the first housing 111 and the second housing 112 may be a rotating shaft. When the first housing 111 and the second housing 112 are in the engaged state, the first speaker 131 disposed on the first housing 111 and the auxiliary magnetic member 132 disposed on the second housing 112 are disposed opposite to each other, and the first speaker 131 and the auxiliary magnetic member 132 attract each other, so that the first housing 111 and the second housing 112 are engaged with each other. In the process of separating the first housing 111 and the second housing 112, that is, when the first housing 111 and the second housing 112 are opened, a repulsive force may be generated between the first speaker 131 and the auxiliary magnetic member 132, so as to weaken or offset the attractive force between the first speaker 131 and the auxiliary magnetic member 132, and make the first speaker 131 and the auxiliary magnetic member 132 repel each other or make the attractive force between the first speaker 131 and the auxiliary magnetic member 132 reduced, so as to facilitate the unfolding of the first housing 111 and the second housing 112.

In the present embodiment, the first speaker 131 may be disposed on the first housing 111 in a region away from the connection portion 120 of the first housing 111 and the second housing 112, for example, in fig. 1, the first speaker 131 is disposed on an edge of the first housing 111 opposite to the connection portion.

In one possible implementation of the embodiment of the present application, as shown in fig. 1, a speaker coil 1311 is disposed in the first speaker 131. Therefore, in one possible implementation manner, when the speaker coil 1311 is switched on by the first current, a repulsive force may be generated between the speaker coil 1311 and the auxiliary magnetic member 132, so that the speaker coil 1311 and the auxiliary magnetic member 132 repel each other. According to ampere's law, when the current is applied to the speaker coil 1311, an electromagnetic field is generated, and by controlling the direction of the first current, the direction of the electromagnetic field is made to be 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 and the auxiliary magnetic member 132 repel each other. So that the attraction force between the first speaker 131 and the auxiliary magnetic member 132 can be reduced, and the user can open the first casing 111 and the second casing 112.

In one possible implementation, as shown in fig. 2, 3a and 3b, first speaker 131 may include a permanent magnet 1312 and a first magnetism spacer sheet 141 disposed at a side of permanent magnet 1312. The first magnetism isolating sheet 141 is provided with a conductive path 151, and in the process of separating the first housing 111 from the second housing 112, the conductive path connects to a second current, and the first magnetism isolating sheet 141 generates a repulsive force repulsive with the auxiliary magnetic member 132, so that the first magnetism isolating sheet 141 and the auxiliary magnetic member 132 repel each other. In this possible implementation manner, when the first speaker 131 normally operates, the magnetic shielding effect of the first magnetic shielding plate 141 can reduce the magnetic influence of the permanent magnet 1312 in the first speaker on other components inside or outside the electronic device, and in the process of separating the first casing 111 and the second casing 112 of the electronic device 110, the conductive path 151 disposed on the first magnetic shielding plate 141 is connected to a second current, so that the conductive path can generate a spiral magnetic field, and at the position where the auxiliary magnetic member 132 is 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 plate 141 and the auxiliary magnetic member 132 repel each other, and thus the attraction force generated by the permanent magnet 1312 on the auxiliary magnetic member 132 can be weakened or cancelled.

In the embodiment of the application, the magnetism isolating sheet is an object capable of changing the direction of the magnetic force lines of the magnetic field. It has very strong magnetic attraction effect, for example, if a magnetic shielding sheet is placed beside the magnet, the magnetic force lines of the magnet will be attracted to the magnetic shielding sheet, and the magnetic field intensity in the space outside the magnetic shielding sheet is reduced.

In the embodiment of the application, the magnetic separation sheet can be made of soft magnetic material, namely the material which can attract magnetic lines in a magnetic field and weaken the magnetic field of other parts. In addition, the magnetism-isolating sheet in the embodiment of the present application may be a conductor, that is, the first magnetism-isolating sheet 141 itself may form a conductive path in which the direction of the second current turned on may be parallel to the circumferential direction of the permanent magnet 1312, so that a magnetic field opposite to the permanent magnet 1312 may be generated at the position of the permanent magnet 1312. For example, the first magnetism isolating sheet 141 may be a steel sheet.

In one possible implementation manner, the first magnetism isolating sheet 141 may be a plurality of sheets, as shown in fig. 3a, and the plurality of first magnetism isolating sheets 141 surround the permanent magnet 1312. The first magnetism isolating pieces 141 are connected to each other by an insulating material 161. The first electrode 1411 and the second electrode 1412 are disposed at both ends of the conductive via 151 of each of the first magnetic separator sheets 141. The plurality of conductive paths 151 are arranged along the circumferential direction of the permanent magnet 1312. That is, in this possible implementation, the plurality of first magnetism isolating pieces 141 are disposed around the permanent magnet 1312, so that the spatial magnetic field strength around the permanent magnet 1312 can be reduced. When the second current is applied to the conductive paths 151 of the first magnetic shield pieces 141, a magnetic field opposite to the permanent magnet 1312 may be generated. For example, assuming that the magnetic field direction of the lower end surface of the permanent magnet 1312 is upward in fig. 3a, a second current as shown in fig. 3b may be conducted to the conductive paths of the plurality of first magnetism-isolating pieces 141, thereby generating a downward magnetic field, so that the first magnetism-isolating pieces 141 and the auxiliary magnetic member 132 may repel each other, and the first case 111 and the second case 112 may be assisted to be unfolded.

In a possible implementation manner, as shown in fig. 3a, any two adjacent first magnetism-isolating sheets 1411 may be bonded by an insulating material 161, which may be plastic or other materials, but is not particularly limited in this embodiment of the application, and each first magnetism-isolating sheet 1411 does not generate current crosstalk to other portions when energized by the insulating material.

In one possible implementation, as shown in fig. 4, the first speaker 131 may include a permanent magnet 1312 and a second magnetism isolating plate 1412 disposed on a target side of the permanent magnet 1312, the second magnetism isolating plate 142 is disposed with an auxiliary coil 1421, the auxiliary coil 1421 is connected with a third current in a process of separating the first casing 111 from the second casing 112, and a magnetic field generated by the auxiliary coil 1421 and a magnetic field generated by the permanent magnet 1312 at one end of the auxiliary magnetic member 132 close to the first speaker 131 are directed to repel each other between the auxiliary coil 1421 and the auxiliary magnetic member 132. When the first housing 111 and the second housing 112 are in the engaged state, the target side is a side of the first speaker 131 far from the second housing 112. That is, the second magnetism isolating sheet 142 is disposed at a side close to the outer surface of the first case 111. When the first loudspeaker 131 works normally, the magnetic separation effect of the second magnetic separation sheet 142 can reduce the magnetic influence of the permanent magnet 1312 in the first loudspeaker 131 on other parts; when the first casing 111 and the second casing 112 of the electronic device 110 are separated, the auxiliary coil 1421 provided on the second magnetism-shielding sheet 142 is energized with a third current, so that 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 magnetism-shielding sheet 142 and the auxiliary magnetic member 132 repel each other, and the attraction force generated by the permanent magnet 1312 on the auxiliary magnetic member 132 can be weakened or cancelled. For example, assuming that the magnetic field of the permanent magnet 1312 is directed upward in fig. 4, a third current as shown in fig. 4 may be conducted to the auxiliary coil 1421 of the second magnetism-shielding plate 142, so as to generate a downward magnetic field (as shown by an arrow in fig. 4), i.e., the downward magnetic field is repelled from the auxiliary magnetic member 132, thereby assisting the expansion of the first casing 111 and the second casing 112.

In one possible implementation of the embodiment of the present application, a plurality of first magnetism isolating pieces 141 and second magnetism isolating pieces 142 may be provided on the first speaker 131 at the same time. As shown in fig. 5, the first magnetic shielding sheets 141 are disposed around the permanent magnet 1312 to enclose a cavity 171. The permanent magnet 1312 is disposed within the cavity 171; the second magnetism isolating sheet 142 is disposed on one end surface of the cavity 171. Under the condition that the first shell 111 and the second shell 112 are in the buckled state, the second magnetism isolating sheet 142 is positioned on one side of the cavity far away from the second shell 112. The second magnetism isolating sheet 142 is provided with an auxiliary coil 1421. The first and second

magnetism isolating pieces

141 and 142 may surround the permanent magnet 1312, reduce interference of a magnetic field generated from respective surfaces of the permanent magnet 1312 with other external magnetic devices, and reduce attractive force between the first speaker 131 and the auxiliary magnetic device 132 when the first case 111 and the second case 112 are unfolded. For example, if the repulsive force between the magnetism isolating plate and the auxiliary magnetic member is greater than the attractive force between the permanent magnet of the first speaker 131 and the auxiliary magnetic member 132, so that the first speaker 131 and the auxiliary magnetic member 132 repel each other, and a gap appears between the first casing 111 and the second casing 112, the user can easily separate the first casing 111 from the second casing 112 with one hand.

In one possible implementation manner of the embodiment of the present application, as shown in fig. 6, the auxiliary magnetic member 132 may include a second speaker 133, and the structure of the second speaker 133 is the same as that of the first speaker 141. That is, the auxiliary magnetic member 132 may be a speaker having the same structure as the first speaker 131. Through the possible implementation manner, the fastening between the first casing 111 and the second casing 112 can be realized by using the attraction force between the permanent magnets in the two speakers oppositely arranged in the electronic device, and when a user needs to open the electronic device, that is, the user needs to separate (or may also be referred to as opening) the first casing 111 and the second casing 112, the two speakers oppositely arranged are mutually exclusive or the attraction force between the two speakers is reduced by connecting corresponding currents to the speakers, so that the user can more easily unfold or separate the first casing 111 and the second casing 112.

In one or more possible implementations, at the opposite ends of the first speaker 131 and the second speaker 133, the permanent magnet in the first speaker 131 is opposite in polarity to the permanent magnet in the second speaker 133. That is, in the engaged state of the first casing 111 and the second casing 112, the first speaker 131 and the second speaker 132 attract each other.

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 repulsive force between the second speaker 133 and the first speaker 132 is generated or the attractive force between the second speaker 133 and the first speaker 132 is reduced. For example, similar to the first speaker 131 described above, a first current may 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 is applied to the first magnetism isolating piece 141 of the second speaker 133, so that a repulsive force is generated between the first magnetism isolating piece 141 of the second speaker 133 and the first speaker. Alternatively, a third current is applied to the second magnetism isolating piece 142 of the second speaker 133, so that a repulsive force is generated between the second magnetism isolating piece 142 of the second speaker 133 and the first speaker.

In one possible implementation manner, as shown in fig. 6, a plurality of first speakers 131 are disposed on the first housing 111, and the plurality of first speakers 131 are uniformly distributed on an 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 on the edge of the second housing 112 away from the connecting portion 120. The first speakers 131 and the auxiliary magnetic members 132 can ensure tight fastening between the first casing 111 and the second casing 112.

In one or more possible implementations, the ends of the permanent magnets of two adjacent first speakers 112 on the first casing 111, which are close to each other, are opposite in magnetism. Therefore, the magnetic field of the whole electronic equipment can be offset, and the interference to other external magnetic devices is reduced as much as possible.

In one possible implementation, the first speaker 131 may include: a permanent magnet 1312, a speaker coil 1311, a plurality of first magnetism isolating pieces 141, and a second magnetism isolating piece 142; the first magnetic separation 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 magnetism isolating sheet 142 is arranged on one end face of the cavity 171, and under the condition that the first shell 111 and the second shell 112 are in a buckling state, the second magnetism isolating sheet 142 is positioned on one side of the cavity 171, which is far away from the second shell 112; the second magnetism isolating sheet 142 is provided with an auxiliary coil 1421; when the first casing 111 and the second casing 112 are in the engaged state, a first attractive force is generated between the permanent magnet 1312 and the auxiliary magnetic member 132; in the process of separating the first housing 111 and the second housing 112, a first attractive force is generated between the permanent magnet 1312 and the auxiliary magnetic member 132, a first repulsive force is generated between the speaker coil 1311 and the auxiliary magnetic member 132, a second repulsive force is generated between the first magnetic separation sheets 141 and the auxiliary magnetic member 132, a third repulsive force is generated between the second magnetic separation sheets 142 and the auxiliary magnetic member 132, and the resultant force of the first repulsive force, the second repulsive force and the third repulsive force is greater than the first attractive force.

In this possible implementation manner, in the process of separating the first casing 111 from the second casing 112, for example, when the first casing 111 and the second casing 112 are unfolded after receiving an external input, repulsive forces that repel each other are provided among the speaker coil 1311 of the first speaker 131, the plurality of first magnetism-isolating pieces 141, the plurality of second magnetism-isolating pieces 142, and the auxiliary magnetic member 132, 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, so that a gap can be generated between the first casing 111 and the second casing 112, thereby facilitating the unfolding of the first casing 111 and the second casing 112.

In one possible implementation manner, when the electronic device is in a falling state, there is a second attractive force between the first speaker 131 and the auxiliary magnetic member 132; wherein the second suction force comprises the first suction force, and the second suction force further comprises at least one of:

a third attractive force between the speaker coil 1311 and the auxiliary magnetic member 132;

a fourth attractive force between the plurality of first magnetism isolating pieces 141 and the auxiliary magnetic member 132;

a fifth attractive force between the second magnetism isolating sheet 142 and the auxiliary magnetic member 132.

For example, a sensor may be disposed in the electronic device, the sensor may detect a motion state of the electronic device, and in a case that 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 may be controlled to conduct a current in a direction opposite to the first current, so that a third attractive force is generated between the speaker coil 1311 and the auxiliary magnetic member 132. The first magnetism isolating pieces 141 may be controlled to be connected with a current opposite to the second current, so that a fourth attractive force is formed between the first magnetism isolating pieces 141 and the auxiliary magnetic member 132. The second magnetism isolating piece 142 may be controlled to be connected with a current in a direction opposite to the third current, so that a fifth attractive force is formed between the second magnetism isolating piece 142 and the auxiliary magnetic member 132.

Through the possible implementation mode, the strength of the anisotropic magnetic field can be identified and enhanced in advance when the whole machine falls under the buckling state, so that the first shell 111 and the second shell 112 are firmly buckled with strong suction force, the falling of the electronic equipment is ensured not to break the first shell 111 and the second shell 112 to cause other more serious problems,

in the foregoing possible implementation manners, the sensor may be a gravity sensor or a gyroscope, which is not specifically limited in the embodiments of the present application.

The electronic device provided in the embodiment of the present application is described below by taking the electronic device as the electronic device shown in fig. 6 as an example.

In this embodiment, the first speaker 131 and the second speaker 133 are speaker switch modules, and as shown in fig. 6, 4 speaker switch modules are symmetrically disposed on the left and right body edges of the electronic device, respectively, and each speaker switch module may include a speaker structure as shown in fig. 7.

As shown in FIG. 7, each speaker includes a speaker coil 1311 formed by winding a movable wire, and includes 4 auxiliary magnets 13121 and a main magnet 13122, where the 4 auxiliary magnets 13121 and the main magnet 13122 together form a permanent magnet 1312, at one end face of the permanent magnet 1312, the main magnet 13122 with the largest center presents N orders upward, and the surrounding ring of auxiliary magnets 13121 presents S orders, and when observed at a position far from the permanent magnet 1312 and facing the center of the permanent magnet 1312, the whole end face of the permanent magnet 1312 presents N orders of characteristics of the central magnet, and only when approaching the edge of the permanent magnet 1312, the permanent magnet 1312 presents S orders of characteristics can be observed.

In the embodiment of the present application, by using the characteristics of the speakers themselves, each pair of the speaker switch modules disposed symmetrically on the left and right bodies of the electronic device (i.e. the first housing 111 and the second housing 112 described above) adopts opposite assembly directions, so that in the fastened state, regardless of the state of the coil being energized, the two speakers will generate attraction force due to the magnetic field of their permanent magnets appearing opposite. Considering that the permanent magnet may attract magnetic substances in the external environment (such as iron filings, iron screws and the like), as shown in fig. 8, each loudspeaker can be further provided with a magnetic shielding sheet to perform 5-surface magnetic shielding sheet wrapping design on the loudspeaker, and only the folding direction opening design is reserved.

According to the ampere rule (namely, the right-hand spiral rule), the electrified lead generates a magnetic field, and the direction of the magnetic field follows the pointing direction of the thumb of the right hand; the magnetic shield sheet of one speaker (including the first speaker 131 and the second speaker 133) is designed according to the following rules:

2. the inside of the first magnetism isolating sheet 141 at the side is a straight wire path, and the left and right sides of the first magnetism isolating sheet 141 are respectively provided with an electrified electrode, wherein the electrode itself has no positive or negative division, and the current flow direction in the first magnetism isolating sheet 141 is controlled by the positive or negative conversion of the driving end. Also, the electrode may be a plating electrode to prevent oxidation;

3. the second magnetic shield 142 at the top is internally provided with a coil formed by surrounding a conducting wire, and the surface of the coil is exposed out of the starting end and the ending end of the conducting wire to be used as electrodes.

Different directional currents are applied in the first magnetism isolating sheet 141 and the second magnetism isolating sheet 142 in a targeted manner, according to the ampere rule, the current is introduced through controlling the first magnetism isolating sheet 141 and the second magnetism isolating sheet 142 and the loudspeaker coil 1311 in the loudspeaker, the permanent magnet magnetic field of the loudspeaker (including the first loudspeaker 131 and the second loudspeaker 133) is superposed, the fastening suction dynamic change of the whole machine can be controlled, the first loudspeaker 131 and the second loudspeaker 133 are changed from opposite-pole suction to same-pole repulsion, and therefore the first shell 111 and the second shell 112 can be automatically bounced off at an angle from the fastening state, and the user can conveniently open the loudspeaker with one hand.

Next, a change in the magnetic field in the process from the engaged state to the deployed state of the first housing 111 and the second housing 112 will be described.

When the whole machine does not operate, the folding screen is buckled, after buckling, the first loudspeaker 131 and the second loudspeaker 133 corresponding to the first shell 111 and the second shell 112 are close to a joint state, fig. 8 shows the magnetism of the opposite surfaces of the first loudspeaker 131 and the second loudspeaker 133, as shown in fig. 8, because the assembling directions of each pair of the first loudspeaker 131 and the second loudspeaker 133 are opposite, namely the first loudspeaker 131 and the second loudspeaker 133 are oppositely assembled, the total magnetic fields of each pair of the first loudspeaker 131 and the second loudspeaker 133 are oppositely attracted after buckling, and therefore the whole machine is locked in the buckling state and is not moved.

In the fastening state of the first housing 111 and the second housing 112, if the user needs to realize the automatic opening angle of the whole machine, the user can input an opening operation command. In particular, the operation command may be input through an input device of the electronic device, the input device may be a physical key or a keyboard, for example, a key provided on the electronic device, or a voice receiving device, for example, a microphone, and the input device may also be a display screen of the electronic device. For example, after the snap-fit, the user may operate on a secondary display of the electronic device (e.g., the secondary display may be disposed on an outer surface of the first housing 111): firstly awakening the auxiliary screen, then, a sliding block prompting automatic opening appears on the auxiliary screen, the sliding block slides to the tail end, namely, the operation instruction is input, and automatic opening operation is triggered.

After receiving the automatic opening operation, the system outputs current to the coils and the external magnetic shielding sheets inside the first speaker 131 and the second speaker 133, so that the magnetic fields of the 8 speakers of the whole machine change to be like poles repelling each other, and the specific process is shown in fig. 9.

As shown in fig. 9, when the whole apparatus is in the initial state, that is, when the first casing 111 and the second casing 112 are in the engaged state, no current flows at this time, the polarity of the magnetic field of the first speaker 141 on the first casing 111 is the S pole, the polarity of the magnetic field of the second speaker 142 on the second casing 112 is the N pole, and the whole apparatus is attracted by the permanent magnet attraction force of the first speaker 131 and the second speaker 133.

When the speaker coils 1311 of the first speaker 131 and the second speaker 133 are energized, the first speaker 141 on the first casing 111 is energized to generate a magnetic field opposite to the magnetic force of the permanent magnet thereof, the overall magnetic force of the first speaker 141 on the first casing 111 is lowered, the second speaker 142 on the second casing 112 is energized to generate a magnetic field identical to the magnetic force of the permanent magnet thereof, at this time, the overall magnetic force of the second speaker 142 on the second casing 112 is increased, at this time, the total magnetic field is substantially unchanged, and the total engaging attraction force is not changed greatly;

when the first and second magnetism-shielding

pieces

141 and 142 of the first and

second speakers

131 and 133 are further energized, the magnetic field generated by the first and second magnetism-shielding

pieces

141 and 142 of the first speaker 131 directly reverses the magnetic field characteristic of the first speaker 131 after the magnetic force is weakened. The total magnetic field of the first speaker 131 has an N-pole polarity, the first and second

magnetism isolating pieces

141 and 142 of the second speaker 133 further enhance the total magnetic field of the second speaker 133, and the total magnetic field of the second speaker 133 still has an N-pole polarity, so that the two speakers can be in a state of being repelled by the same poles, and the whole speaker can be opened by the repulsive force.

In the process that the whole machine is opened at an angle, because the distance between the first loudspeaker 131 and the second loudspeaker 133 is increased, the magnetic field is exponentially reduced along with the distance, the total fastening suction force between the first loudspeaker 131 and the second loudspeaker 133 is rapidly reduced, and after the suction force is reduced to 0, the whole machine is opened a little distance again due to inertia. After the buckling action is triggered to be finished (namely, in an integrally opened state), the first magnetic shielding sheet 141, the second magnetic shielding sheet 142 and the loudspeaker coil 1311 stop being electrified, at the moment, the first loudspeaker 131 and the second loudspeaker 133 recover to an initial state and present magnetic fields with the same size and opposite polarities, and because the whole machine is opened at a certain angle, the symmetrical first loudspeaker 131 and the symmetrical second loudspeaker 133 are too far away, and at the moment, the buckling suction force can be ignored, so that the whole machine can not be buckled back again, the damping in the rotating shaft can stop the folding equipment at the automatically opened angle, and a user can easily unfold the whole machine after the angle is opened by using one hand.
