Background

With the rapid development of electronic devices, users have increasingly strong demands for electronic devices with large screens (such as mobile phones with large screens). However, the mobile phone with a large screen is inconvenient to carry. Therefore, the mobile phone with the foldable screen, the screen of which can be stretched and deformed, is produced. In order to remind a user that the folding screen mobile phone receives a message, the folding screen mobile phone is provided with a music mode and a vibration mode. Taking the vibration mode as an example, when the folding screen mobile phone receives a message, the folding screen mobile phone prompts the user through vibration.

And because the position of the mass center of the folding screen mobile phone in the unfolding state is different from the position of the mass center of the folding screen mobile phone in the folding state, the vibration quantity of the folding screen mobile phone in the unfolding state and the folding state is greatly different.

The embodiment of the application provides an electronic device, which can comprise a folding device and a flexible display screen fixed on the folding device. The folding device can be unfolded to a flat state (also called an unfolding state), can also be folded to a closed state (also called a folding state), and can also be in an intermediate state between the flat state and the closed state. The flexible display screen is unfolded and folded along with the folding device.

Referring to fig. 1 to 6 together, fig. 1 is a schematic structural diagram of an electronic device 1000 provided in an embodiment of the present application in a flat state, fig. 2 is a schematic structural diagram of a folding apparatus 100 of the electronic device 1000 shown in fig. 1 in a flat state, fig. 3 is a schematic structural diagram of the electronic device 1000 shown in fig. 1 in an intermediate state, fig. 4 is a schematic structural diagram of the folding apparatus 100 of the electronic device 1000 shown in fig. 3 in an intermediate state, fig. 5 is a schematic structural diagram of the electronic device 1000 shown in fig. 1 in a closed state, and fig. 6 is a schematic structural diagram of the folding apparatus 100 of the electronic device 1000 shown in fig. 5 in a closed state. The electronic device 1000 may be a foldable product such as a mobile phone, a tablet computer, a notebook computer, etc. The embodiment is described by taking the electronic device 1000 as a folding screen mobile phone as an example.

The electronic device 1000 includes a folding apparatus 100 and a flexible display 200. The folding device 100 includes a first housing 10, a rotating mechanism 20, and a second housing 30 connected in this order. The first casing 10 may include a middle frame and a rear cover, and the second casing 30 may include a middle frame and a rear cover. The rotating mechanism 20 can be deformed to rotate the first casing 10 and the second casing 30 around the rotating mechanism 20, so that the electronic device 1000 is in a flat state, an intermediate state or a closed state. As shown in fig. 1 and fig. 2, the first casing 10 and the second casing 30 can be relatively unfolded to a flat state, so that the electronic apparatus 1000 is in the flat state. Illustratively, the angle α between the first housing 10 and the second housing 30 in the flattened state may be approximately 180 ° (some deviation is also allowed, such as 165 °, 177 °, or 185 °). As shown in fig. 3 and 4, the first casing 10 and the second casing 30 can be relatively rotated (unfolded or folded) to an intermediate state, so that the electronic apparatus 1000 is in the intermediate state. As shown in fig. 5 and 6, the first casing 10 and the second casing 30 can be folded relatively to a closed state, so that the electronic device 1000 is in the closed state. Illustratively, when the first housing 10 and the second housing 30 are in the closed state, the two housings can be substantially completely folded to be parallel to each other (a slight deviation is also allowed). The intermediate state shown in fig. 3 and 4 may be any state between the flat state and the closed state. Therefore, the electronic device 1000 can be switched between the unfolded state and the closed state by the deformation of the rotating mechanism 20.

The flexible display 200 is fixed to the folding device 100 so as to be able to be unfolded or folded with the folding device 100. Illustratively, the flexible display 200 may be adhered to the folding device 100 by a glue layer. The flexible display panel 200 includes a first non-bending portion 2001, a bending portion 2002, and a second non-bending portion 2003 arranged in this order. The first non-bending portion 2001 of the flexible display 200 is fixed to the first housing 10, the second non-bending portion 2003 is fixed to the second housing 30, and the bending portion 2002 deforms when the first housing 10 and the second housing 30 are folded or unfolded relatively. As shown in fig. 1, when the first housing 10 and the second housing 30 are in the flat state, the flexible display screen 200 is in the flat state, and can display in a full screen, so that the electronic device 1000 has a larger display area to improve the viewing experience of a user; as shown in fig. 3, when the first casing 10 and the second casing 30 are in the intermediate state, the flexible display 200 is in the intermediate state between the flat state and the closed state; as shown in fig. 5, when the first casing 10 and the second casing 30 are in the closed state, the flexible display 200 is in the closed configuration. When the electronic device 1000 is in the closed state, the flexible display 200 is located outside the folding device 100, and the flexible display 200 may be substantially U-shaped. When the electronic device 1000 is in the closed state, the plane size of the electronic device 1000 is small, which is convenient for the user to carry and store.

Fig. 1, fig. 3 and fig. 5 are schematic diagrams showing deformation of the rotating mechanism 20 during the process of relatively folding the electronic device 100 from the flat state to the closed state. As shown in fig. 1, when the electronic device 1000 is in the flattened state, the length of the bending portion 2002 of the flexible display screen 200 is a first length L1, the length of the rotating mechanism 20 is a second length L2, and the first length L1 is equal to the second length L2. As shown in fig. 3, when the electronic device 1000 is in the intermediate state, the length of the bending portion 2002 of the flexible display 200 is still the first length L1, the rotating mechanism 20 is deformed, the length is changed to a third length L3, and the third length L3 is smaller than the second length L2. As shown in fig. 5, when the electronic device 1000 is in the closed state, the length of the bending portion 2002 of the flexible display 200 is still the first length L1, the rotating mechanism 20 is deformed, the length is changed to the fourth length L4, and the fourth length L4 is smaller than the third length L3. Therefore, the flexible display 200 can maintain a constant length by the deformation of the rotating mechanism 20 during the unfolding or folding process of the electronic device 1000.

In some embodiments, the flexible display 200 is used to display images. Exemplarily, the flexible display panel 200 may be an Organic Light-Emitting Diode (OLED) display panel, an Active Matrix Organic Light-Emitting Diode (AMOLED) display panel or an Active Matrix Organic Light-Emitting Diode (Active-Matrix Organic Light-Emitting Diode), a Mini Light-Emitting Diode (Mini Organic Light-Emitting Diode) display panel, a Micro Light-Emitting Diode (Micro Organic Light-Emitting Diode) display panel, a Micro Organic Light-Emitting Diode (Micro Organic Light-Emitting Diode) display panel, a Quantum Dot Light-Emitting Diode (QLED) display panel.

The flexible display 200 is a multi-layer structure, for example, including: the first electrode layer, the dielectric thin layer, and the second electrode layer are bonded together by, for example, an Optical Clear Adhesive (OCA), wherein the OCA has elasticity.

It should be noted here that the first housing and the second housing may both be provided with screens. Alternatively, one of the first and second housings may be provided with a screen. Or, the first shell and the second shell are not provided with screens. In addition, the first housing and the second housing may be formed as an integral two-part structure, such as a screen folded into two parts. Alternatively, the first housing and the second housing may be two separate members.

In some embodiments, the electronic apparatus 1000 may further include a plurality of modules (not shown), and the plurality of modules may be received inside the folding device 100. The plurality of modules of the electronic device 1000 may include, but are not limited to, a motherboard, a processor, a memory, a driver, a motor, a battery, a camera module, an earpiece module, a speaker module, a microphone module, an antenna module, a sensor module, and the like, as described in detail below. Wherein the processor, the driver, the motor, etc. are integrated on the motherboard. The number, type, and position of the modules of the electronic device 1000 are not specifically limited in the embodiment of the present application.

In an electronic apparatus, a first portion of a folding device 100, which may include a first driving circuit, a first motor, is disposed in an accommodation space formed by a middle frame and a rear cover of a first housing. The processor controls the first driving circuit to output a driving signal, and the driving signal is used for controlling the first motor to vibrate so as to drive the electronic equipment to vibrate. Because the electronic equipment is large in size and heavy in weight, when the electronic equipment is in an unfolded state, the mass center of the electronic equipment is located at a first position, the distance between the position of the first motor and the first position is greater than a first preset value, and at the moment, the first motor drives the electronic equipment to vibrate violently; when the electronic equipment is in a folded state, the mass center of the electronic equipment is located at a second position, the distance between the position of the first motor and the second position is smaller than or equal to a first preset value, and at the moment, the first motor drives the electronic equipment to vibrate in a weaker mode. It can be seen that there is a large difference in the amount of vibration of the electronic device in the unfolded state and the folded state.

In order to solve the above problem, embodiments of the present application provide another electronic device. In this electronic apparatus, in comparison with the above-described electronic apparatus, a first part of the folding device 100 is provided in the accommodating space of the first housing, and a second part of the folding device 100 is provided in the accommodating space of the second housing. The second portion may include a second motor. Wherein the vibration directions of the first motor and the second motor are related to the settings of the two motors and the state of the electronic device.

Wherein, the setting of two motors can include the setting position of two motors and the setting direction of two motors, and wherein, the setting position of two motors can be understood as: the first motor and the second motor in the plurality of modules of the electronic device 1000 are disposed on a circuit board of the electronic device, and the first motor and the second motor may be disposed on the first circuit board or the second circuit board of the electronic device, respectively, for example, the first motor is disposed on the first circuit board, and the second motor is disposed on the second circuit board; the first circuit board is located in the accommodating space of the first shell, and the second motor is located in the accommodating space of the second shell. For example, in the unfolded state of the electronic apparatus, the vibration direction of the first motor with respect to the electronic apparatus is the same as the vibration direction of the second motor with respect to the electronic apparatus. For example, in the unfolded state of the electronic apparatus, the vibration direction of the first motor may be the first direction shown in fig. 7, and at the same time, the vibration direction of the second motor with respect to the electronic apparatus and the vibration direction of the first motor with respect to the electronic apparatus may be the same, and also the first direction. In one embodiment, as shown in fig. 7, the first circuit board 1 is disposed between the first housing 10 and the flexible display screen, the first surface 11 of the first circuit board 1 faces the flexible display screen, and the first motor 80 is disposed on the first surface 11 of the first circuit board 1; the second circuit board 2 is arranged between the second shell 30 and the flexible display screen, the first surface 21 of the second circuit board 2 faces the flexible display screen, and the second motor 90 is arranged on the first surface 21 of the second circuit board 2; the vibration direction of the first motor may be a direction from the first circuit board to the flexible display screen and perpendicular to the first circuit board, and at the same time, the vibration direction of the second motor with respect to the electronic device is the same as the vibration direction of the first motor with respect to the electronic device.

Whether the two motors are disposed on the first side or the second side of the main board, the mapped positions of the two motors on the housing may be referred to as the positions of the motors on the housing. In one particular implementation, the first position of the first motor on the first housing may be a first predetermined distance from a center of mass of the first housing, and the second position of the second motor on the second housing may be a second predetermined distance from the center of mass of the second housing. The first preset distance and the second preset distance may be set according to actual conditions, and the embodiment of the present application is not particularly limited.

Optionally, the first preset distance and the second preset distance may both refer to a distance farthest from the centroid. That is, the first position of the first motor on the first housing may be a position farthest from the center of mass of the first housing, and the second position of the second motor on the second housing may be a position farthest from the center of mass of the second housing, in consideration of the maximum amount of vibration at a position away from the respective modules on the main body. That is, in one example, a location away from the aggregation of the modules is selected in consideration of the aggregation of the modules on the first and second housings.

For example, the first motor may be disposed at an edge of the first housing, and the second motor may be disposed at an edge of the second housing.

For example, assuming that the centroid position of the first housing is the geometric center of the first housing, the first motor is disposed at the farthest position from the geometric center of the first housing, i.e., at one top corner of the first housing. Similarly, assuming that the centroid position of the second housing is the geometric center of the second housing, the second motor is disposed at the position farthest from the geometric center of the second housing, i.e., at a top corner of the second housing. For example:

example 1, fig. 7 is a schematic structural diagram of another electronic device 1000 according to an embodiment of the present disclosure, in which a folding apparatus 100 is in a flat state. As shown in fig. 7, assume that: when the electronic device 1000 is in the unfolded state, the first motor 80 is disposed on a surface of the first casing 10 facing the flexible display screen, and the second motor 90 is disposed on a surface of the second casing 30 facing the flexible display screen. When the electronic apparatus 1000 is in the unfolded state, the first motor 80 and the second motor 90 are located at positions almost symmetrical with respect to the rotation mechanism 20; when the electronic apparatus 1000 is in the folded state, the first motor 80 and the second motor 90 are located at least partially overlapping with respect to the thickness direction of the electronic apparatus.

Of course, the arrangement positions of the first motor and the second motor are not limited to the positions in the above examples, and the first motor and the second motor may also be arranged in a mirror image manner with respect to the folding shaft, and the embodiments of the present application are not listed.

The state of the electronic device refers to that the electronic device is in an unfolded state or the electronic device is in a folded state.

Wherein the vibration directions of the first motor and the second motor may include:

the vibration direction of the first motor relative to the electronic device and the vibration direction of the second motor relative to the electronic device may be the same. The first and second motors may be the same type and model. In one embodiment, assuming that the electronic device is in the unfolded state and the rotation mechanism is used as a reference, the vibration direction timing sequence of the first motor 80 is as shown in fig. 8: the method comprises the following steps of (1) circulating from time 0 to time t1, wherein the vibration direction is the first direction → time t1 to time t2, the vibration direction is the second direction → time t2 to time t3, and the vibration direction is the first direction, \ 8230; \ 8230, and so on; the vibration direction sequence of the second motor 90 sequentially corresponds to the vibration timing of the first motor 80: starting from time 0 to time t1, the vibration direction is the first direction → time t1 to time t2, the vibration direction is the second direction → time t2 to time t3, the vibration direction is the first direction, 8230, and so on. The first direction may be a direction toward the rotating mechanism from the first motor 80 when the electronic device is in the unfolded state; or the electronic equipment is in an unfolded state, and the second motor is far away from the rotating mechanism; or the electronic equipment is in an unfolded state and is vertical to and faces the direction of the first circuit board; or the electronic equipment is in an unfolded state and is vertical to and faces the direction of the second circuit board; the second direction is the electronic device unfolding state, and is the direction away from the rotating mechanism by the first motor 80; or the electronic equipment is in an unfolded state, and the second motor faces the direction of the rotating mechanism; or the electronic equipment is in an unfolded state and is perpendicular to and far away from the first circuit board; or the electronic device is in an unfolded state, and the direction is perpendicular to and far away from the second circuit board. The first motor and the second motor are respectively located at both sides of the rotating mechanism, and it can be seen that, in the unfolded state of the electronic apparatus, the vibration direction of the first motor 80 with respect to the electronic apparatus and the vibration direction of the second motor 90 with respect to the electronic apparatus coincide.

The waveform of the driving signal for driving the first motor and the second motor to vibrate may be a square wave or a sine wave. Taking the waveforms of the first driving signals of the first motor 80 and the second motor 90 as square waves as an example, as shown in fig. 8, the square waves of the first driving signals correspond to the vibration directions of the first motor 80 and the second motor 90, when the electronic device is in the unfolded state, in a time period from 0 to t1, the vibration direction of the first motor is the first direction, and the vibration direction of the second motor is the first direction; in the time period from t1 to t2, the vibration direction of the first motor is a second direction, and the vibration direction of the second motor is a second direction; in the time period from t2 to t3, the vibration direction of the first motor is a first direction, and the vibration direction of the second motor is a first direction; in the time period from t3 to t4, the vibration direction of the first motor is the second direction, and the vibration direction of the second motor is the second direction. Therefore, when the electronic apparatus is in the unfolded state, the vibration direction of the first motor 80 with respect to the electronic apparatus and the vibration direction of the second motor 90 with respect to the electronic apparatus are the same. In the embodiment of the present application, the electronic apparatus may be an external folding electronic apparatus, and when the electronic apparatus is folded outwards along the folding direction in fig. 7 into the folding state shown in fig. 9 (or when the electronic apparatus is folded outwards along the folding direction in fig. 10 into the folding state shown in fig. 12), the first casing 10 is rotated 180 ° with respect to the rotating mechanism, and accordingly, the first motor 80 located on the first casing 10 is also rotated 180 ° with respect to the rotating mechanism. When the electronic device is in the folded state and the driving signal for driving the motor to vibrate is not changed relative to the driving signal for driving the motor to vibrate when the electronic device is in the unfolded state, the vibration direction of the first motor 80 relative to the electronic device and the vibration direction of the second motor 90 relative to the electronic device will be opposite, the vibration intensities of the two motors will be offset, and the vibration intensity of the electronic device in the folded state will be weakened relative to the vibration intensity of the unfolded state. For example, as shown in fig. 8, the vibration directions of the two motors in the folded state may be: in the time period from 0 to t1, the vibration direction of the first motor is a third direction, and the vibration direction of the second motor is a fourth direction; in the time period from t1 to t2, the vibration direction of the first motor is a fourth direction, and the vibration direction of the second motor is a third direction; in the time period from t2 to t3, the vibration direction of the first motor is a third direction, and the vibration direction of the second motor is a fourth direction; in the time period from t3 to t4, the vibration direction of the first motor is the fourth direction, and the vibration direction of the second motor is the third direction. The third direction may be a direction in which the electronic device is in a folded state and the first motor 80 faces the rotating mechanism; or the electronic equipment is in a folding state, and the second motor faces the direction of the rotating mechanism; or the electronic equipment is in a folding state and is vertical to and faces the direction of the first circuit board; or the electronic equipment is in a folding state and is vertical to and far away from the direction of the second circuit board; the fourth direction is that the electronic device is in a folded state and is far away from the rotating mechanism by the first motor 80; or the electronic equipment is in a folding state and is far away from the direction of the rotating mechanism by the second motor; or the electronic equipment is in a folding state and is vertical to and far away from the direction of the first circuit board; or the electronic equipment is in a folded state and is perpendicular to and faces to the direction of the second circuit board.

Continuing with example 2, as shown in fig. 10, when the first motor and the second motor employ a z-axis linear motor. Similarly to the above-described embodiment, when the electronic apparatus is in the unfolded state, the vibration direction of the first motor 80 with respect to the electronic apparatus and the vibration direction of the second motor 90 with respect to the electronic apparatus are the same. When the electronic device is in the folded state and the driving signal for driving the motor to vibrate is not changed, the vibration direction of the first motor 80 relative to the electronic device and the vibration direction of the second motor 90 relative to the electronic device will be opposite, the two vibration intensities will cancel out, and the vibration intensity of the electronic device in the folded state will be weaker than that in the unfolded state.

In order to solve the problem that the vibration strength of the electronic equipment in the folding state is weakened in the prior art, the vibration directions of the two motors are controlled by the electronic equipment in the folding or unfolding state. The method can be realized in the following ways:

first, as shown in fig. 13, which is a schematic block diagram of the electronic device shown in fig. 7 and 10, the electronic device 1000 may further include a first driving circuit 60 for driving the first motor 80, a second driving circuit 70 for driving the second motor 90, and a processor 40. Wherein the processor 40 is connected to the first drive circuit 60 and the second drive circuit 70. When the electronic device 1000 is in the unfolded state, the processor controls the first driving circuit and the second driving circuit to output driving signals, and controls the vibration direction of the first motor 80 relative to the electronic device to be the same as the vibration direction of the second motor 90 relative to the electronic device.

In one embodiment, when the electronic device 1000 is in the unfolded state, the processor 40 controls the first driving circuit 60 and the second driving circuit 70 through the first control information to control the vibration direction of the first motor 80 relative to the electronic device to be the same as the vibration direction of the second motor 90 relative to the electronic device. The processor 40 sends the first control information to the first drive circuit 60 and the second drive circuit 70. The first and

second driving circuits

60 and 70 receive the first control information, and the first and

second driving circuits

60 and 70 may output driving signals of the same phase, respectively, according to the first control information, for example, the first and

second driving circuits

60 and 70 output the driving signal 1 as shown in fig. 14. The first drive circuit 60 and the second drive circuit 70 output first drive signals of the same phase. Thus, the vibration direction of the first motor 80 with respect to the electronic device and the vibration direction of the second motor 90 with respect to the electronic device are the same under the driving of the first drive circuit 60 and the second drive circuit 70. When the electronic device 1000 is in the folded state, the processor 40 controls the first drive circuit 60 and the second drive circuit 70, and the vibration direction of the first motor 80 with respect to the electronic device is the same as the vibration direction of the second motor 90 with respect to the electronic device. The first driving circuit 60 outputs a driving signal according to the control information of the memory, the phase of which may be opposite with respect to the phase of the waveform of the driving signal output by the second driving circuit 70 according to the control information of the memory, e.g., the first driving circuit 60 outputs a driving signal 2 as shown in fig. 14, and the second driving circuit 70 outputs a driving signal 1 as shown in fig. 14. The phase of the driving signal output from the first driving circuit 60 and the phase of the driving signal output from the second driving circuit 70 may be opposite. For example, as shown in fig. 11, at time 0 to t1, the vibration direction of the first motor is the third direction, and the vibration direction of the second motor is the third direction; in the time period from t1 to t2, the vibration direction of the first motor is the fourth direction, and the vibration direction of the second motor is the fourth direction; in the time period from t2 to t3, the vibration direction of the first motor is a third direction, and the vibration direction of the second motor is the third direction; in the time period from t3 to t4, the vibration direction of the first motor is the fourth direction, and the vibration direction of the second motor is the fourth direction. The third direction may be a direction in which the electronic device is in a folded state and the first motor 80 faces the rotating mechanism; or the electronic equipment is in a folding state, and the second motor faces the direction of the rotating mechanism; or the electronic equipment is in a folding state and is vertical to and faces to the direction of the first circuit board; or the electronic equipment is in a folding state and is vertical to and far away from the direction of the second circuit board; the fourth direction is that the electronic device is in a folded state and is far away from the rotating mechanism by the first motor 80; or the electronic equipment is in a folding state and is far away from the direction of the rotating mechanism by the second motor; or the electronic equipment is in a folding state and is vertical to and far away from the direction of the first circuit board; or the electronic equipment is in a folded state and is perpendicular to and faces to the direction of the second circuit board.

In this way, in the folded state of the electronic apparatus, the first motor is driven by the driving signal 1, and the second motor is driven by the driving signal 2, the vibration direction of the first motor 80 with respect to the electronic apparatus and the vibration direction of the second motor 90 with respect to the electronic apparatus are the same.

In the embodiment of the present application, in the case where the position and direction of the motor on the circuit board are determined, the electronic device may preset the waveform phase of the driving signal so that the vibration direction of the first motor 80 with respect to the electronic device and the vibration direction of the second motor 90 with respect to the electronic device are the same. For example, when the first motor and the second motor are the same in type and style, the first motor and the second motor may be respectively disposed on a first circuit board or a second circuit board of the electronic device, for example, the first motor is disposed on the first circuit board, and the second motor is disposed on the second circuit board; the first circuit board is located in the accommodating space of the first shell, and the second motor is located in the accommodating space of the second shell. The first circuit board is arranged between the first shell and the flexible display screen, the first surface of the first circuit board faces the flexible display screen, and the first motor is arranged on the first surface of the first circuit board; the second circuit board is arranged between the second shell and the flexible display screen, the first surface of the second circuit board faces the flexible display screen, and the second motor is arranged on the first surface of the second circuit board. In the unfolded state, the layout direction of the first motor with respect to the electronic apparatus is the same as the layout direction of the second motor with respect to the electronic apparatus. Under such a preset condition, when the electronic device is in the unfolded state, when the phase of the driving signal output from the first driving circuit 60 is the same as the phase of the driving signal output from the second driving circuit 70, the vibration direction of the first motor with respect to the electronic device is the same as the vibration direction of the second motor with respect to the electronic device. The embodiments of the present application are described by way of example. When the layout direction of the first motor and the layout direction of the second motor are different, a person skilled in the art may adjust the phase of the driving signal output by the first driving circuit 60 and the phase of the driving signal output by the second driving circuit according to the specific design requirement and the embodiments of the present application, so that when the electronic device is in the unfolded state or the folded state, the vibration direction of the first motor and the vibration direction of the second motor are the same

Illustratively, as shown in fig. 15, following the above example 1, in the folded state, the phase of the waveform of the drive signal output from the first drive circuit 60 is opposite to the phase of the drive signal output from the second drive circuit 70. For example, the first drive circuit 60 outputs the drive signal 2 shown in fig. 14, and the second drive circuit 70 outputs the drive signal 1 shown in fig. 14. When the electronic apparatus is in the folded state, the phase of the driving signal output from the first driving circuit 60 is opposite to the phase of the driving signal output from the first driving circuit 60 when the electronic apparatus is in the unfolded state. Thus, when the state of the electronic device changes, the phase of the driving signal output by the first driving circuit changes, which causes the absolute vibration direction of the first motor to change, but the vibration direction of the first motor with respect to the electronic device remains unchanged. Therefore, in the folded state, the vibration direction of the first motor with respect to the electronic apparatus and the vibration direction of the second motor with respect to the electronic apparatus are also the same.

A second mode, different from the first mode, is that when the electronic device is in the folded state, the processor outputs second control information to the second driving circuit, and in response to the second control information, the second driving circuit outputs a first driving signal, such as driving signal 1 shown in fig. 14; the processor outputs third control information to the first drive circuit, and the first drive circuit outputs a second drive signal in response to the third control information; the first driving signal and the second driving signal are opposite phase signals. The first driving circuit receives the third control information sent by the processor and outputs a second driving signal, such as driving signal 2 shown in fig. 14, according to the third control information. The first drive circuit outputs a second drive signal. In this way, the electronic apparatus is in the folded state, and the vibration direction of the first motor with respect to the electronic apparatus is the same as the vibration direction of the second motor with respect to the electronic apparatus.

Third, as shown in fig. 16, for a schematic block diagram of an electronic device provided in an embodiment of the present application, the electronic device 1000 may further include an inverter 110. The inverter 110 is disposed between the first driver 60 and the first motor 80. When the electronic device is in the unfolded state, the electronic device controlling the first driver 60 and the second driver 70 may output the same control signal, which is directly used to control the first motor and the second motor to vibrate, so that the vibration direction of the first motor with respect to the electronic device and the vibration direction of the second motor with respect to the electronic device are the same. When the electronic device is in the folded state, the electronic device controlling first driver 60 and second driver 70 may output the same control signal, which is directly used to control the vibration of the first motor, and the control signal controls the vibration of the second motor through the inverter 110, so that the vibration direction of the first motor with respect to the electronic device and the vibration direction of the second motor with respect to the electronic device are the same.

Therefore, the embodiment of the application enables the vibration directions of the first motor and the second motor relative to the electronic equipment to be the same when the electronic equipment is in the folded state and the unfolded state, so that the vibration quantity of the first motor and the vibration quantity of the second motor are superposed when the electronic equipment is in the folded state or the unfolded state, thereby increasing the vibration quantity of the electronic equipment and shortening the difference between the vibration quantities of the folded state and the unfolded state of the electronic equipment.

In other embodiments, as shown in fig. 17, which is a schematic block diagram of an electronic device provided in the embodiment of the present application, the electronic device 1000 may further include a detection circuit 120 for acquiring first information of the first casing 10 and/or the second casing 30. The detection circuit 120 collects first information of the first casing 10 and/or the second casing 30 and transmits the collected first information to the processor 40. The processor 40 determines the state of the electronic device 1000, which may include a folded state and an unfolded state, according to the first information collected by the detection circuit 120.

Wherein the first information may refer to information for characterizing the attitude of the first shell and/or the second shell. Such as acceleration values, angular velocities or magnetic field strengths in a plurality of directions.

The detection circuit 120 may include an acceleration sensor and/or a gyroscope sensor, among others. For example, as shown in fig. 17, for a schematic structural diagram of an electronic device provided in an embodiment of the present application, the detection circuit 120 includes a first acceleration sensor 121 and a second acceleration sensor 122, the first acceleration sensor 121 is disposed on the first casing 10, and the second acceleration sensor 122 is disposed on the second casing 30. Alternatively, the detection circuit may further include a hall sensor and a magnet cooperating with the hall sensor. The Hall sensor is arranged on the first shell, the magnet is arranged on the second shell, and the Hall sensor and the magnet are in mirror symmetry.

Taking the detection circuit as an acceleration sensor as an example, it is assumed that the second housing is horizontally placed. The acceleration sensor is disposed in the first housing. The acceleration sensor acquires acceleration values of the first housing in a plurality of dimensions (e.g., x-axis, y-axis, and z-axis). And the processor receives the acceleration values acquired by the acceleration sensor in all dimensions. The processor determines the state of the electronic device according to the relationship of the acceleration values between the dimensions. For example, if the component of the first acceleration value acquired by the acceleration sensor on the z-axis on the y-axis is greater than the first set value and the component on the x-axis is less than the second set value, the processor determines that the electronic device is in the folded state; if the component of a first acceleration value acquired by the acceleration sensor on the z axis on the y axis is smaller than or equal to a first set value, and the component on the x axis is larger than or equal to a second set value, the processor determines that the electronic equipment is in the unfolding state.

In another concrete implementation manner, the number of the acceleration sensors is two, and the two acceleration sensors include a first acceleration sensor and a second acceleration sensor. As shown in fig. 18, the first acceleration sensor 121 is provided on the first casing 10, and the second acceleration sensor 122 is provided on the second casing 30. The first acceleration sensor 121 acquires acceleration values of the first casing 10 in a plurality of directions (e.g., x-axis, y-axis, and z-axis). The second acceleration sensor 122 acquires acceleration values of the second casing 30 in a plurality of directions (e.g., x-axis, y-axis, and z-axis). The processor 40 receives acceleration values in various directions acquired by the first acceleration sensor 121 and acceleration values in various directions acquired by the second acceleration sensor 122. The processor 40 determines the posture of the first casing 10 from the relationship of the acceleration values between the respective directions acquired by the first acceleration sensor 121, determines the posture of the second casing 30 from the relationship of the acceleration values between the respective directions acquired by the second acceleration sensor 122, and determines the state of the electronic apparatus 1000 from the posture of the first casing 10 and the posture of the second casing 30.

In some embodiments, taking the detection circuit 120 as a gyro sensor as an example, the gyro sensor may be used to determine a motion gesture of the electronic device. In some embodiments, the number of gyro sensors is two, the two gyro sensors including a first gyro sensor and a second gyro sensor. A first gyro sensor is disposed on the first housing, the first gyro sensor acquiring angular velocities of the first housing about three axes (i.e., x, y and z axes). A second gyro sensor is provided on the second housing, the second gyro sensor acquiring angular velocities of the second housing about three axes (i.e., x, y and z axes). The processor receives the angular velocities on the respective axes acquired by the first gyro sensor and the angular velocities on the respective axes acquired by the second gyro sensor. The processor determines the attitude of the first housing based on the angular velocities acquired by the first gyroscope sensor in each axis. The processor determines the attitude of the second housing based on the angular velocities acquired by the second gyroscope sensor in each axis. The processor determines the state of the electronic device according to the posture of the first shell and the posture of the second shell.

In another specific implementation, the detection circuit 120 may further include a hall sensor and a magnet cooperating with the hall sensor. The Hall sensor and the magnet mirror image are arranged on two sides of the folding shaft. The Hall sensor detects the intensity of magnetic field and sends the acquired data to the processor. The processor determines the state of the electronic device according to the magnetic field intensity detected by the Hall sensor. For example, if the magnetic field strength detected by the hall sensor is greater than a first threshold, the processor determines that the electronic device is in a folded state; if the magnetic field intensity detected by the Hall sensor is smaller than or equal to a first threshold value, the processor determines that the electronic equipment is in the unfolding state.

In another specific implementation manner, the acceleration sensor, the hall sensor and the magnet can be arranged on the first shell and the second shell simultaneously. The processor combines the acceleration values acquired by the acceleration sensor on all dimensions and the magnetic field intensity acquired by the Hall sensor to determine the state of the electronic equipment. For example, if the component of the first acceleration value acquired by the first acceleration sensor on the z axis on the y axis is greater than a first set value, the component on the x axis is less than a second set value, and the magnetic field strength acquired by the hall sensor is greater than a third set value, the processor determines that the electronic device is in the folded state; if the component of the first acceleration value acquired by the first acceleration sensor on the z axis on the y axis is less than or equal to a first set value, the component on the x axis is greater than or equal to a second set value, and the magnetic field intensity acquired by the Hall sensor is less than or equal to a third set value, the processor determines that the electronic equipment is in the unfolding state.

Of course, the states of the electronic devices may also be determined in other combinations of the above examples, and the embodiments of the present application are not listed in this application.

Based on the structure of the electronic device in the above embodiment, the embodiment of the present application provides a vibration control method. Fig. 19 is a flowchart illustrating a vibration control method according to an embodiment of the present application. The vibration control method is suitable for electronic equipment (such as a folding screen mobile phone) and the like mentioned in the embodiment of the application.

As shown in fig. 19, the method may include:

s2100, the electronic equipment acquires a vibration event.

The vibration event can be triggered and generated by touch operation of a user, and can also be triggered and generated by the electronic equipment receiving a specified prompt event. The touch operation may be an operation that a user triggers a screen of the electronic device to input an instruction for controlling the electronic device to generate a corresponding operation, and the designated prompt event may be an event for receiving a short message, an event for receiving an instant messaging message, an event for receiving a notification message, an event for receiving an incoming call, or the like.

For example, when the vibration event is triggered and generated by a touch operation of a user, the step may be: the electronic equipment receives the input touch operation and determines an event responding to the touch operation as a vibration event. When the vibration event is triggered and generated by the electronic device receiving a specified prompt event, the step may be: when the electronic equipment detects a specified prompting event, the electronic equipment determines the specified prompting event as a vibration event.

S2200, the electronic device determines whether the electronic device is in a folded state or an unfolded state.

S2200 may be specifically embodied as:

s2210, the electronic device collects the first information.

Wherein the first information may be information for characterizing the first housing and/or the second housing. Such as acceleration, angular velocity, magnetic field strength, etc.

The execution subject for acquiring the first information of the first shell and/or the second shell may be a detection circuit. The detection circuit may be of an electronic device or of another device. The detection circuit may include a hall sensor and a magnet cooperating with the hall sensor. The detection circuit may also be an acceleration sensor and/or a gyro sensor. The detection circuit may also be a combination of hall sensors and magnets, and acceleration sensors and/or gyro sensors.

Example 1, take an example that the detection circuit may include a hall sensor and a magnet that are arranged in mirror image on both sides of a folding axis of the electronic device. Accordingly, S2210 may be specifically implemented as: and S2211, detecting the magnetic field intensity by the Hall sensor.

Example 2, taking as an example that the detection circuit includes an acceleration sensor, the detection circuit may include: at least one acceleration sensor, which may include a first acceleration sensor disposed on a first housing of the electronic device and a second acceleration sensor disposed on a second housing of the electronic device. Accordingly, S2210 may be specifically implemented as: and S2212, acquiring the acceleration of the first shell in each direction, and acquiring the acceleration of the second shell in each direction. Illustratively, the first acceleration sensor acquires acceleration values of the first housing in a plurality of directions (e.g., x-axis, y-axis, and z-axis). The second acceleration sensor acquires acceleration values of the second housing in a plurality of directions (e.g., x-axis, y-axis, and z-axis).

Example 3, taking as an example that the detection circuit includes a gyro sensor, the detection circuit may include: at least one gyro sensor, which may include a first gyro sensor and a second gyro sensor. The first gyro sensor is disposed on a first housing of the electronic device, and the second gyro sensor is disposed on a second housing of the electronic device. Accordingly, S2210 may be specifically implemented as: s2213, collecting angular velocities of the first shell around the respective axes, and collecting angular velocities of the second shell around the respective axes.

S2220, the electronic device determines that the electronic device is in a folded state or an unfolded state according to the first information.

Continuing with example 1, the hall sensor detects the magnetic field strength and sends the detected data to the processor of the electronic device. The processor determines the state of the electronic device according to the magnetic field intensity detected by the Hall sensor. For example, if the magnetic field strength detected by the hall sensor is greater than a first threshold, the processor determines that the electronic device is in a folded state; if the magnetic field intensity detected by the Hall sensor is smaller than or equal to a first threshold value, the processor determines that the electronic equipment is in the unfolding state.

Illustratively, the processor determines the attitude of the first housing based on a component of the acceleration values acquired by the first acceleration sensor in the z-axis in the y-axis and a component in the x-axis. The processor determines the attitude of the second housing based on the component of the acceleration value acquired by the second acceleration sensor in the z-axis in the y-axis and the component in the x-axis. The processor determines the state of the electronic device according to the posture of the first shell and the posture of the second shell.

Following example 3, the first gyroscope sensor acquires angular velocities of the first housing about three axes (i.e., x, y, and z axes). A second gyro sensor is provided on the second housing, the second gyro sensor acquiring angular velocities of the second housing about three axes (i.e., x, y and z axes). The processor receives the angular velocities on the respective axes acquired by the first gyro sensor and the angular velocities on the respective axes acquired by the second gyro sensor. The processor determines the attitude of the first housing based on the angular velocities acquired by the first gyroscope sensor in each axis. The processor determines the attitude of the second housing based on the angular velocities acquired by the second gyroscope sensor in each axis. The processor determines the state of the electronic device according to the posture of the first shell and the posture of the second shell.
