For a better understanding of the embodiments of the present disclosure, the driver 1 in the related art is explained below by way of an exemplary embodiment:

as shown in fig. 1, an embodiment of the present disclosure provides a driver 1, the driver 1 including:

a member to be driven 11 capable of elastic deformation;

a first spring member 14 and a second spring member 15 respectively provided at both ends of the member 11 to be driven;

a vibrator assembly 12, the vibrator assembly 12 comprising a first magnet 121, the first magnet 121 comprising a first magnetic pole and a second magnetic pole; the first magnetic pole is connected with one end of the piece 11 to be driven through a first spring piece 14; the second magnetic pole is connected with the other end of the piece 11 to be driven through a second spring piece 15;

Here, when the first magnet 121 moves under the force, the first spring member 14 and the second spring member 15 may not efficiently transmit the force acting on the magnet to the driving member 11, resulting in a large loss of force and poor vibration effect of the driving member 11; the first magnet 121 may strike the driving member 11 during vibration and generate abnormal sounds, resulting in poor user experience; in some application scenarios, the vibration stroke of the magnet needs to be obtained through complex calculation, so that the impact between the magnet and the member 11 to be driven is reduced, and the waste of calculation force resources is caused; the first spring element 14 and the second spring element 15 also present a risk of spring breakage.

After the driving signal is removed, the vibrator assembly 12 gradually reduces the vibration stroke under the preset damping condition on the basis of the simple harmonic vibration. When a plurality of driving signals are concurrent, a plurality of debugging means can be adopted to prevent the first magnet 121 from being impacted with the to-be-driven member 11 so as to avoid abnormal sound, for example, the driving signals corresponding to the braking waveforms can be added to the sub-assembly 13, so that the vibrator is triggered to quickly return, for example, a safe interval can be reserved among the plurality of driving signals, and even the waveform amplitude of the driving signals can be reduced. The above approach is complex to operate and affects the user experience.

In one embodiment, the specific number of the first magnets 121 may not be limited, and only a repulsive force or attractive force capable of generating an interaction between the vibrator assembly 12 composed of the first magnets 121 and the stator assembly 13 may be ensured. Illustratively, vibrator assembly 12 may include only one first magnet 121 disposed opposite stator assembly 13. Alternatively, vibrator assembly 12 may include at least two first magnets 121 disposed opposite stator assembly 13, respectively.

In one embodiment, the type of interaction force generated between the stator assembly 13 and each of the first magnets 121 is the same. For example, vibrator assembly 12 includes two first magnets 121, magnet a and magnet B for each of the two first magnets 121, and at the same time, the type of force generated between stator assembly 13 and magnet a is the same as the type of force generated between stator assembly 13 and magnet B.

In one embodiment, the driver 1 comprises: a member to be driven 11 capable of elastic deformation; a stator assembly 13, the stator assembly 13 including a second magnet 131 and a coil 132 disposed around the second magnet 131; one end close to each other between the second magnet 131 and the coil 132 jointly forms a first end of the stator assembly 13, the other end close to each other between the second magnet 131 and the coil 132 jointly forms a second end of the stator assembly 13, and the first end and the second end of the stator assembly 13 have different magnetism under the condition that current passes through the coil 132 of the stator assembly 13; vibrator assembly 12 disposed opposite stator assembly 13, vibrator assembly 12 including a first predetermined number of first magnets 121 toward a first end and a second predetermined number of first magnets 121 toward a second end, at least one pole of each first magnet 121 being fixedly coupled to member 11 to be driven. The first predetermined number of first magnets 121 have first poles facing the first end, and the second predetermined number of first magnets 121 have second poles facing the second end. The first magnetic pole and the second magnetic pole are different. An interactive repulsive force or attractive force can be generated between the vibrator assembly 12 and the stator assembly 13. Here, the first magnetic pole may be a south pole and the second magnetic pole may be a north pole; alternatively, the first pole may be a north pole and the second pole may be a south pole. Here, the magnetic poles facing the first end of the two magnetic poles included in the first magnet 121 facing the first end and the magnetic poles facing the second end of the two magnetic poles included in the first magnet 121 facing the second end can be made different, so that the types of the forces of the interactions generated between the stator assembly 13 and the respective first magnets 121 are the same, the situation that the forces cancel each other due to the different types of the forces generated between the stator assembly 13 and the respective first magnets 121 is reduced, the loss of the forces is reduced, and the vibration effect of the member 11 to be driven is good.

In one embodiment, the driver 1 comprises: the member to be driven 11 is capable of elastic deformation. Vibrator assembly 12, vibrator assembly 12 includes first magnet 121, at least one magnetic pole of first magnet 121 with wait to drive piece 11 fixed connection. A stator assembly 13 disposed opposite to the vibrator assembly 12, the stator assembly 13 including a second magnet 131 and a coil 132 disposed around the second magnet 131; a coil 132 disposed around the second magnet 131 is used for receiving alternating current and triggering the magnetic pole of the second magnet 131 to change under the action of the alternating current; an interactive repulsive force or attractive force can be generated between the vibrator assembly 12 and the stator assembly 13. It is understood that in the case where the magnetic poles of the second magnet 131 are changed, the repulsive force generated between the vibrator assembly 12 and the stator assembly 13 is converted into attractive force, or the attractive force between the vibrator assembly 12 and the stator assembly 13 is converted into repulsive force. At this time, under the action of the alternating current, the vibrator assembly 12 reciprocates relative to the stator assembly 13 through the attraction and repulsion continuously changing between the vibrator assembly 12 and the stator assembly 13, so as to drive the member to be driven 11 fixedly connected with the vibrator assembly 12 to vibrate.

In one embodiment, the distance between vibrator assembly 12 and stator assembly 13 is a predetermined distance within which a repulsive or attractive interaction can occur between vibrator assembly 12 and stator assembly 13.

The coils 132 of the stator assembly 13 of the drive 1 may be used to: the driving signal is received and the magnetic pole of the second magnet 131 is triggered to change under the action of the driving signal. Here, since at least one magnetic pole of the first magnet 121 of the vibrator assembly 12 is connected to the driving member 11, the driving member 11 can be elastically deformed, and thus, when an interactive repulsive force or attractive force is generated between the vibrator assembly 12 and the stator assembly 13, the first magnet 121 can directly drive the driving member 11 to reciprocate under the repulsive force or attractive force, thereby driving the driving member 11 to vibrate. At this time, for a specific driving waveform, the waveform of the motor single force can be intuitively reflected; since the vibration stroke of the vibrator assembly 12 does not need to be considered, a brake waveform does not need to be specially designed; for complex vibration scenes, driving signals corresponding to different vibration waveforms can be directly overlapped without considering the problems of waveform breaking and waveform safety interval debugging, so that the driver 1 provided in the embodiment of the disclosure has very strong experience supporting force on the multi-mode vibration scenes.

In the embodiment of the present disclosure, the driver 1 includes: a member to be driven 11 capable of elastic deformation; a vibrator assembly 12, wherein the vibrator assembly 12 comprises a first magnet 121, and at least one magnetic pole of the first magnet 121 is fixedly connected with the member to be driven 11; a stator assembly 13 disposed opposite to the vibrator assembly 12, the stator assembly 13 including a second magnet 131 and a coil 132 disposed around the second magnet 131; an interactive repulsive force or attractive force can be generated between the vibrator assembly 12 and the stator assembly 13. Here, since at least one magnetic pole of the first magnet 121 of the vibrator assembly 12 is connected to the driving member 11, the driving member 11 can be elastically deformed, and thus, when an interactive repulsive force or attractive force is generated between the vibrator assembly 12 and the stator assembly 13, the first magnet 121 can directly drive the driving member 11 to reciprocate under the repulsive force or attractive force, thereby driving the driving member 11 to vibrate. Compared to the manner of driving the member to be driven 11 to vibrate by providing the connecting member between the magnet and the member to be driven 11 in the related art, the first magnet 121 and the member to be driven 11 are fixedly connected in the embodiment of the disclosure, and the member to be driven 11 is directly driven to vibrate by the force acting on the first magnet 121 without providing the connecting member between the first magnet 121 and the member to be driven 11. In this way, the loss of force can be reduced, the force acting on the first magnet 121 is not required to be transmitted to the member 11 to be driven through the connecting piece, the transmission efficiency of the force to the member 11 to be driven can be improved, and the vibration effect of the member 11 to be driven is good; in the case where the first magnet 121 is fixedly connected with the driving member 11, the first magnet 121 does not collide with the driving member 11, and abnormal sound caused by the collision of the first magnet 121 with the driving member 11 can be reduced; the calculation step of the vibration stroke of the first magnet 121 can be simplified without calculating and adjusting the movement stroke of the first magnet 121 to avoid the collision of the first magnet 121 with the driving member 11.
