Description

Technical Field

[0001] The present invention relates to the technical field of vibration devices, and in particular to an exciter and electronic equipment using the exciter. Background Art

[0002] Traditional vibration devices create the illusion of a force acting in a certain direction by continuously producing asymmetric vibrations. This type of vibration is also called anisotropic vibration.

[0003] There are currently two ways to achieve this force sense: one is to input an asymmetric signal into the linear resonator and use the human senses to create an illusion. In principle, this method can only produce a continuous directional force sense and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and the asymmetric signal will also produce redundant vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong sense of force by rapidly braking the linear resonator. This method can generate vibrations with large asymmetry, and has a small proportion of redundant vibrations, and the force sense is independent and clear. However, this method requires that the vibration part and the braking part are independently constructed, and the vibration part or the braking part is continuously moved to switch the energy storage and braking states, resulting in its inability to operate continuously at high speed, and the device structure is complex.

[0046] Traditional vibration devices create the illusion of a force acting in a certain direction by continuously producing asymmetric vibrations. This type of vibration is also called anisotropic vibration.

[0047] There are currently two ways to achieve this force sense: one is to input an asymmetric signal into the linear resonator and use the human senses to create an illusion. In principle, this method can only produce a continuous directional force sense and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and the asymmetric signal will also produce redundant vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong sense of force by rapidly braking the linear resonator. This method can generate vibrations with large asymmetry, and has a small proportion of redundant vibrations, and the force sense is independent and clear. However, this method requires that the vibration part and the braking part are independently constructed, and the vibration part or the braking part is continuously moved to switch the energy storage and braking states, resulting in its inability to operate continuously at high speed, and the device structure is complex.

[0048] Based on the above concepts and problems, the present invention proposes an actuator 100. It can be understood that the actuator 100 is applied to electronic devices, and the electronic devices can be tactile displays, tactile interfaces, force feedback devices, vibrating feeders, beauty products, personal hygiene products, personal entertainment products, personal massagers, woodcutters, and earthquake vibrators. For example, wireless controllers for games, mobile motion controllers for sports games, wireless steering wheels, and remote controllers for sports games in game consoles, etc., are not limited here.

[0049] Please refer to Figures 1 to 4 As shown, in an embodiment of the present invention, the exciter 100 includes a shell 1, multiple driving members 2 and multiple rotating parts 3, the shell 1 has an installation cavity 11 and a first side wall 12, the multiple driving members 2 are arranged in the installation cavity 11 at intervals, the number of driving members 2 is an even number, at least one rotating part 3 is connected to the output end of each driving member 2, and is eccentrically arranged, and the number of rotating parts 3 is an even number; wherein the two driving members 2 synchronously drive the two rotating parts 3 to rotate, so that the two rotating parts 3 hit the first side wall 12 at the same time.

[0050] In this embodiment, the housing 1 of the exciter 100 is used to install, fix and protect the driving member 2 and the rotating part 3 and other components, that is, the housing 1 provides a mounting structure for the driving member 2 and the rotating part 3 and other components. It can be understood that the housing 1 can be a mounting shell, a mounting box, a box body and other structures, which are not limited here. The housing 1 has a mounting cavity 11 for placing and installing the driving member 2 and the rotating part 3 and other components. The mounting cavity 11 can be a closed cavity, and of course the mounting cavity 11 can also be an open cavity.

[0051] It is understandable that the housing 1 can be an integral structure or a split structure. In order to facilitate the disassembly and assembly of components such as the drive member 2 and the rotating portion 3, the housing 1 can be optionally configured as a split body. That is, the housing 1 includes a first housing and a second housing, which are butt-connected and enclosed to form an installation cavity 11. It should be noted that the housing 1 can be a regular shape or an irregular shape, such as a regular shape such as a circle, an ellipse, a direction, a triangle or other polygon, or other irregular shapes, which are not limited here.

[0052] In this embodiment, the shell 1 has a first side wall 12, and the first side wall 12 can be the outer wall of the shell 1, or it can be a side wall or partition structure arranged in the installation cavity 11 of the shell 1, which is not limited here. Optionally, the shell 1 is arranged in a square shape. Further, the shell 1 can be optionally a rectangular structure. The first side wall 12 can be optionally the bottom wall of the shell 1, and the shell 1 also has two vertical side walls connected to the first side wall 12, and the two vertical side walls are located at both ends of the first side wall 12. At this time, half of the multiple driving members 2 are arranged close to one vertical side wall, and the other half of the driving members 2 are arranged close to the other vertical side wall.

[0053] It can be understood that the number of half of the driving members 2 is the same as that of the other half of the driving members 2, and they are symmetrically arranged relative to the center line perpendicular to the first side wall 12. In this embodiment, the driving member 2 and the rotating part 3 cooperate to form a rotating assembly. Each driving member 2 can have one output end or two output ends. When the driving member 2 has two output ends, the two output ends are located on the axis of the driving member 2. Optionally, each rotating part 3 is connected to the output end of a driving member 2 and is eccentrically arranged.

[0054] In this embodiment, the driving member 2 may be directly fixed to the inner wall of the housing 1, or may be installed in the installation cavity 11 through other structures, such as a bracket or a mounting seat. It can be understood that the rotating part 3 may be an eccentric structure, or one end of the rotating part 3 may be connected to the output end of the driving member 2, so that when the driving member 2 drives the rotating part 3 to rotate, the rotating part 3 performs a circular motion around the output end of the driving member 2, that is, the position where the rotating part 3 is connected to the output end of the driving member 2 is located at the eccentric position of the rotating part 3 structure itself (the position where the rotating part 3 is connected to the output end of the driving member 2 does not coincide with the center of the rotating part 3).

[0055] It can be understood that by simultaneously controlling multiple driving members 2 to drive multiple rotating parts 3 to rotate, multiple rotating parts 3 simultaneously hit the first side wall 12 or the vertical side wall, that is, when multiple rotating parts 3 simultaneously hit the first side wall 12, the exciter 100 forms a force sense in a single linear direction, and when multiple rotating parts 3 simultaneously hit the vertical side wall, multiple rotating parts 3 generate forces of the same magnitude and opposite directions on the vertical side wall, thereby offsetting each other, so that the exciter 100 obtains a force sense in a single linear direction.

[0056] It should be noted that the actuator 100 also includes a controller or a control structure, which can simultaneously control multiple driving members 2 to drive multiple rotating parts 3 to rotate. It can be understood that the controller or control structure can be a separate controller or remote control, or a control circuit or control button integrated on the actuator 100, which is not limited here.

[0057] The exciter 100 of the present invention forms an installation cavity 11 in the shell 1, so as to use the installation cavity 11 to install, fix and protect the driving member 2 and the rotating part 3. A plurality of driving members 2 are arranged at intervals in the installation cavity 11, and the number of driving members 2 is set to an even number, and at least one rotating part 3 among the plurality of rotating parts 3 is connected to the output end of each driving member 2, and is eccentrically arranged, and the number of rotating parts 3 is set to an even number. In this way, when the plurality of driving members 2 are controlled to synchronously drive the plurality of rotating parts 3 to rotate, the plurality of rotating parts 3 are simultaneously used to hit the first side wall 12, so that the exciter 100 forms a force sense in a single linear direction; at the same time, the exciter 100, by setting a plurality of driving members 2 to respectively drive the rotating structure of the plurality of eccentrically arranged rotating parts 3, not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous action and generate a strong and clear force sense in a single linear direction.

[0058] In one embodiment, the shell 1 is further provided with a second side wall 13, one end of which is connected to the first side wall 12, and divides the installation cavity 11 into a first cavity 111 and a second cavity 112; part of the driving members 2 are arranged in the first cavity 111, and part of the driving members 2 are arranged in the second cavity 112, the number of driving members 2 in the first cavity 111 is the same as the number of driving members 2 in the second cavity 112, and the number of rotating parts 3 in the first cavity 111 is the same as the number of rotating parts 3 in the second cavity 112; wherein, multiple driving members 2 synchronously drive multiple rotating parts 3 to rotate, so that multiple rotating parts 3 simultaneously hit the first side wall 12 or the second side wall 13.

[0059] In this embodiment, if Figures 1 to 4As shown, by arranging the second side wall 13 in the installation cavity 11 of the housing 1, one end of the second side wall 13 is connected to the first side wall 12, and the installation cavity 11 is divided into a first cavity 111 and a second cavity 112. It can be understood that the first cavity 111 and the second cavity 112 can be closed cavities spaced from each other, or can be open cavities or cavities connected to each other, which is not limited here. Optionally, one end of the second side wall 13 is connected to the first side wall 12, and the other end of the second side wall 13 is connected to the side wall opposite to the first side wall 12.

[0060] Optionally, the housing 1 is arranged in a square shape. Further, the housing 1 may be arranged in a rectangular structure. In this embodiment, the first side wall 12 and the second side wall 13 are arranged vertically and are located in the middle of the first side wall 12. That is, the second side wall 13 divides the installation cavity 11 in half, so that the first cavity 111 and the second cavity 112 are arranged symmetrically relative to the second side wall 13, that is, the second side wall 13 is located between the two vertical side walls and is parallel to the two vertical side walls.

[0061] Of course, in other embodiments, the second side wall 13 may not be arranged perpendicular to the first side wall 12. For example, when the rotating portion 3 is arranged in a fan shape, when the driving member 2 drives the rotating portion 3 to rotate 90° to collide with the first side wall 12 or the second side wall 13, the first side wall 12 and the second side wall 13 may not be arranged perpendicularly, which is not limited here. It can be understood that the first side wall 12 can be arranged as a two-section structure arranged at an angle, in which case the second side wall 13 is connected to the angle of the first side wall 12, and in which case the second side wall 13 is not arranged perpendicularly to at least one section of the first side wall 12, which is not limited here.

[0062] In this embodiment, half of the driving members 2 are arranged in the first cavity 111 and the other half are arranged in the second cavity 112 , so that the number of half of the driving members 2 is the same as that of the other half, and they are symmetrically arranged relative to the second side wall 13 . It can be understood that half of the multiple driving members 2 are arranged close to a vertical side wall, and the other half of the driving members 2 are arranged close to the other vertical side wall; or, the multiple driving members 2 in the first cavity 111 are arranged close to the second side wall 13, and the driving members 2 in the second cavity 112 are arranged close to the second side wall 13; or, some of the multiple driving members 2 in the first cavity 111 are arranged close to a vertical side wall, and some of the driving members 2 are arranged close to the second side wall 13, and some of the driving members 2 in the second cavity 112 are arranged close to the other vertical side wall, and some of the driving members 2 are arranged close to the second side wall 13. As long as the number of driving members 2 in the first cavity 111 is the same as the number of driving members 2 in the second cavity 112, and they are symmetrically arranged relative to the second side wall 13, no limitation is made here.

[0063] It can be understood that by simultaneously controlling multiple driving members 2 to drive multiple rotating parts 3 to rotate, multiple rotating parts 3 simultaneously hit the first side wall 12 or the second side wall 13 / vertical side wall, that is, when multiple rotating parts 3 simultaneously hit the first side wall 12, the exciter 100 forms a force sense in a single linear direction, and when multiple rotating parts 3 simultaneously hit the second side wall 13 / vertical side wall, multiple rotating parts 3 generate forces of the same magnitude and opposite directions on the second side wall 13 / vertical side wall, thereby offsetting each other, so that the exciter 100 obtains a force sense in a single linear direction.

[0064] In one embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, there are two driving members 2 and two rotating parts 3 . One driving member 2 is disposed in the first cavity 111 , and the other driving member 2 is disposed in the second cavity 112 . Each rotating part 3 is connected to the output end of one driving member 2 .

[0065] In this embodiment, if Figure 3 As shown, the two driving members 2 are controlled to drive the two rotating parts 3 to rotate at the same time, and the two rotating parts 3 hit the first side wall 12 at the same time, thereby forming a single linear force sense on the housing 1 of the actuator 100; Figure 4 As shown, the two driving members 2 are controlled simultaneously to drive the two rotating parts 3 to rotate, and the two rotating parts 3 hit the second side wall 13 at the same time, and the two rotating parts 3 generate forces of the same magnitude and opposite directions on the second side wall 13, thereby offsetting each other. This ensures the force sense of the two rotating parts 3 hitting the first side wall 12 at the same time, so that the exciter 100 can generate a strong and clear force sense in a single straight line direction.

[0066] It can be understood that the exciter 100 is defined to have a first state in which the two driving members 2 are simultaneously controlled to drive the two rotating parts 3 to rotate and the two rotating parts 3 simultaneously hit the first side wall 12, and a second state in which the two driving members 2 are simultaneously controlled to drive the two rotating parts 3 to rotate and the two rotating parts 3 simultaneously hit the second side wall 13. Figure 5 As shown, when the acceleration sensor is used to detect the vibration of the actuator 100, in the first state, the shell 1 of the actuator 100 has an obvious downward vibration sense and a unidirectional touch sense; in the second state, the shell 1 of the actuator 100 has basically no vibration sense.

[0067] The exciter 100 of the present invention forms an installation cavity 11 in the shell 1, so that the installation cavity 11 is used to install, fix and protect the driving member 2 and the rotating part 3, and a second side wall 13 is set in the installation cavity 11 of the shell 1, so that one end of the second side wall 13 is connected to the first side wall 12, and the installation cavity 11 is divided into a first cavity 111 and a second cavity 112, so that a driving member 2 and a rotating part 3 are installed in the first cavity 111 and the second cavity 112 respectively, so that each rotating part 3 is connected to the output end of a driving member 2 and is eccentrically arranged, so that when the two driving members 2 are controlled to synchronously drive the two rotating parts 3 to rotate, the two rotating parts 3 are used to simultaneously hit the first side wall 111 and the second side wall 112. Wall 12 or the second side wall 13, that is, when the two rotating parts 3 hit the first side wall 12 at the same time, the exciter 100 forms a force sense in a single linear direction, and when the two rotating parts 3 hit the second side wall 13 at the same time, the two rotating parts 3 generate forces of the same magnitude and opposite directions on the second side wall 13, thereby offsetting each other, so that the exciter 100 obtains a force sense in a single linear direction; at the same time, the exciter 100 is provided with two driving members 2 to respectively drive the rotating structure of the two eccentrically arranged rotating parts 3, which not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous action and generate a strong and clear force sense in a single linear direction.

[0068] In one embodiment, if Figures 1 to 4 As shown, each driving member 2 is a rotor motor, which is provided with a rotating shaft 21 , and each rotating part 3 is provided with an axial hole 31 , which is eccentrically arranged on the rotating part 3 , and the rotating shaft 21 is passed through the axial hole 31 .

[0069] It is understandable that the structure of the rotating part 3 can be a regular shape or an irregular shape. Optionally, the shape of the rotating part 3 can be circular, elliptical, square, triangular or polygonal. The center of the shaft hole 31 does not coincide with the shape of the rotating part 3. Of course, the shape of the rotating part 3 can also be an irregular shape, which is not limited here.

[0070] In this embodiment, by setting the driving member 2 as a rotor motor and utilizing the rotor motor to drive the rotating structure of the eccentrically arranged rotating part 3, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and generate a strong and clear sense of force.

[0071] It should be noted that, in order to further ensure that the actuator 100 generates a strong and clear force sensation in a single straight line direction, two sets of rotating components consisting of a driving member 2 and a rotating part 3 are symmetrically arranged in the first cavity 111 and the second cavity 112. Optionally, the weight of the plurality of rotating parts 3 is the same. The shape and contour of the plurality of rotating parts 3 are the same.

[0072] It can be understood that in order to further ensure that the actuator 100 generates a strong and clear force sensation in a single linear direction, the driving frequencies of the multiple driving members 2 are the same and the driving voltages of the multiple driving members 2 are the same.

[0073] In one embodiment, each rotating part 3 includes at least one mass block 32. It can be understood that the material of the mass block 32 can be a metal material, that is, the mass block 32 is made of a metal material. Of course, the mass block 32 can also be a non-metallic material, that is, the mass block 32 is made of a non-metallic material.

[0074] It should be noted that, in order to make the exciter 100 produce a strong and clear sense of force, the mass block 32 of the rotating part 3 adopts a relatively heavy structure, and optionally, the mass block 32 is made of metal. In order to further improve the mass of the rotating part 3, the rotating part 3 can also be provided with a counterweight block or multiple mass blocks 32 on the mass block 32, and the counterweight block or multiple mass blocks 32 are located in the radial direction or circumferential direction of the rotation center of the rotating part 3, and the shaft hole 31 is located in the eccentric position of the formed integral rotating part 3 (that is, the shaft hole 31 does not coincide with the center of the formed integral rotating part 3).

[0075] In one embodiment, if Figure 2 As shown, each rotating part 3 includes three mass blocks 32, one mass block 32 is connected to the output end of a driving member 2 and is eccentrically arranged; the other two mass blocks 32 are connected and arranged in sequence along the radial direction of the rotating part 3; or, the other two mass blocks 32 are connected and arranged in sequence along the circumferential direction of the mass block 32.

[0076] In this embodiment, if Figures 1 to 4 As shown, the number of mass blocks 32 of each rotating part 3 can be one, two, three, four or more, etc., which is not limited here. The shaft hole 31 on the mass block 32 connected to the rotating shaft 21 of the driving member 2 among the multiple mass blocks 32 is located at the eccentric position of the mass block 32, and at this time, another mass block 32 is connected to the radial direction or circumferential direction of the mass block 32, and the distance from the other mass block 32 to the shaft hole 31 is greater than the distance from the other mass block 32 to the center of the mass block 32.

[0077] Of course, the shaft hole 31 may also be located at the center of the mass block 32 , and in this case another mass block 32 is connected to one side of the mass block 32 , so that the overall rotating portion 3 has an eccentric structure, which is not limited here.

[0078] In one embodiment, if Figure 3 and Figure 4As shown, each driving member 2 is arranged near the connection between the first side wall 12 and the second side wall 13, so that the two driving members 2 are symmetrically arranged relative to the second side wall 13. It can be understood that the first cavity 111 and the second cavity 112 are symmetrically arranged relative to the second side wall 13. Optionally, the first cavity 111 and the second cavity 112 are arranged in a square. When the number of driving members 2 is multiple and the number of driving members 2 is an even number, the multiple driving members 2 in the first cavity 111 and the multiple driving members 2 in the second cavity 112 are symmetrically arranged relative to the second side wall 13.

[0079] Of course, in other embodiments, the multiple driving members 2 in the first cavity 111 are arranged at intervals along the connection between the first side wall 12 and the second side wall 13, and the multiple driving members 2 in the second cavity 112 are arranged at intervals along the connection between the first side wall 12 and the second side wall 13, that is, the multiple driving members 2 are arranged at intervals along the extended length direction of the second side wall 13; and / or, the multiple driving members 2 in the first cavity 111 are arranged at intervals along the connection between the first side wall 12 and the vertical side wall, and the multiple driving members 2 in the second cavity 112 are arranged at intervals along the connection between the first side wall 12 and the vertical side wall, that is, the multiple driving members 2 are arranged at intervals along the extended length direction of the vertical side wall, which is not limited here.

[0080] In one embodiment, the driving members 2 include two, the rotating parts 3 include two, one driving member 2 is arranged in the first cavity 111, and the other driving member 2 is arranged in the second cavity 112, and each rotating part 3 is connected to the output end of one driving member 2; it is defined that when the two rotating parts 3 hit the first side wall 12 at the same time, the two rotating parts 3 respectively form first impact points 121 on the first side wall 12, and the distances from the two first impact points 121 to the second side wall 13 are the same.

[0081] In this embodiment, if Figure 3 As shown, in order to ensure that the distances from the two first impact points 121 formed by the two rotating parts 3 hitting the first side wall 12 at the same time to the second side wall 13 are the same, so that the force sense generated by the exciter 100 in a single straight line direction is consistent and the user experience is improved, the output end of each driving member 2 (that is, the rotation center of the rotating part 3) is located on the bisector of the angle formed by the first side wall 12 and the second side wall 13.

[0082] In one embodiment, the driving members 2 include two, the rotating parts 3 include two, one driving member 2 is disposed in the first cavity 111, and the other driving member 2 is disposed in the second cavity 112, and each rotating part 3 is connected to the output end of one driving member 2; it is defined that when the two rotating parts 3 hit the second side wall 13 at the same time, the two rotating parts 3 form a second impact point 131 on the second side wall 13, and the distances from the two second impact points 131 to the first side wall 12 are the same.

[0083] In this embodiment, if Figure 4As shown, in order to ensure that the distances between the two second impact points 131 formed by the two rotating parts 3 simultaneously hitting the second side wall 13 and the first side wall 12 are the same, that is, the two second impact points 131 coincide on the second side wall 13, and the forces formed by the two rotating parts 3 simultaneously hitting the second side wall 13 offset each other, so as to ensure that the exciter 100 can generate a strong and clear sense of force in a single straight line direction, thereby enhancing the user's sense of experience, the output end of each driving member 2 (that is, the rotation center of the rotating part 3) is located on the bisector of the angle formed by the first side wall 12 and the second side wall 13.

[0084] In one embodiment, if Figure 1 , Figure 3 and Figure 4 As shown, each driving member 2 drives a rotating part 3 to rotate by an angle of 90°. It can be understood that the first side wall 12 and the second side wall 13 of the housing 1 are optionally arranged vertically, and the second side wall 13 is located in the middle of the first side wall 12. Each driving member 2 is arranged near the connection between the first side wall 12 and the second side wall 13. Optionally, the driving member 2 is located on the diagonal line of the angle formed by the first side wall 12 and the second side wall 13.

[0085] It can be understood that the rotating part 3 is located on the side of the driving member 2 facing away from the angle formed by the first side wall 12 and the second side wall 13, so that the driving member 2 drives the rotating part 3 to rotate 90°, so that the rotating part 3 hits the first side wall 12 or the second side wall 13.

[0086] Of course, each driving member 2 drives a rotating part 3 to rotate at an angle greater than 90° or less than 90°. It should be noted that when the line between the rotating shaft 21 of the driving member 2 and the center of the rotating part 3 is not parallel to the first side wall 12 or the second side wall 13, the driving member 2 drives the rotating part 3 to rotate at an angle greater than 90° or less than 90°, which is not limited here.

[0087] It can be understood that when the two rotating parts 3 hit the first side wall 12 at the same time, the line between the rotating axis 21 of the driving member 2 and the center of the rotating part 3 is not parallel to the first side wall 12, and when the two rotating parts 3 hit the second side wall 13 at the same time, the line between the rotating axis 21 of the driving member 2 and the center of the rotating part 3 is not parallel to the second side wall 13. At this time, the angle at which the driving member 2 drives a rotating part 3 to rotate can also be greater than 90° or less than 90°, which is not limited here.

[0088] In this embodiment, if Figure 3 As shown, it is defined that one driving member 2 drives the rotating part 3 to rotate forward, that is, the driving member 2 rotates forward, and the other driving member 2 drives the rotating part 3 to rotate reversely, that is, the driving member 2 rotates reversely, so that when the two driving members 2 drive the two rotating parts 3 to rotate, the two rotating parts 3 hit the first side wall 12 at the same time. Figure 4As shown, it is defined that one driving member 2 drives the rotating part 3 to rotate in the opposite direction, that is, the driving member 2 rotates in the opposite direction, and the other driving member 2 drives the rotating part 3 to rotate in the forward direction, that is, the driving member 2 rotates in the forward direction, so that when the two driving members 2 drive the two rotating parts 3 to rotate, the two rotating parts 3 hit the second side wall 13 at the same time.

[0089] In one embodiment, it is defined that when the rotating part 3 collides with the first side wall 12 or the second side wall 13, an impact point is formed on the first side wall 12 and the second side wall 13, and the exciter 100 also includes a buffer part 4; the buffer part 4 is arranged on the first side wall 12 and / or the second side wall 13 and is located at the impact point; or, the buffer part 4 is arranged on the rotating part 3, and when the driving member 2 drives the rotating part 3 to rotate, the buffer part 4 abuts against the impact point.

[0090] In this embodiment, if Figures 1 to 4 As shown, by providing the buffer part 4, the buffer part 4 can be used to adjust the impact force of the buffer rotating part 3, and the buffer part 4 can be used to adjust the susceptible frequency of the vibration wave, so that Figure 5 The tip of the middle wave peak is sharper, and at the same time, the buffer portion 4 also has a noise reduction effect.

[0091] It can be understood that when the rotating part 3 collides with the first side wall 12 or the second side wall 13, the collision point formed on the first side wall 12 and the second side wall 13 coincides with the first impact point 121 and the second impact point 131 of the collision point. In this embodiment, the buffer part 4 can be arranged on the first side wall 12 and / or the second side wall 13 of the housing 1, and is located at the first impact point 121 and / or the second impact point 131. Of course, the buffer part 4 can also be arranged on the rotating part 3, so that when the driving member 2 drives the rotating part 3 to rotate, the buffer part 4 abuts against the first impact point 121 and / or the second impact point 131.

[0092] In this embodiment, the buffer part 4 includes a plurality of buffer parts 4, and the plurality of buffer parts 4 are respectively arranged on the first side wall 12 and the second side wall 13. Alternatively, the plurality of buffer parts 4 are arranged on opposite sides of the rotating part 3, so that when the rotating part 3 hits the first side wall 12, the first side wall 12 abuts against the buffer part 4, or when the rotating part 3 hits the second side wall 13, the second side wall 13 abuts against the buffer part 4, etc., which is not limited here.

[0093] Optionally, the buffer part 4 is made of a compressible material, such as foam, sponge, rubber pad, etc., which is not limited here. That is, the buffer part 4 is not made of a rigid material.

[0094] In this embodiment, the driving member 2 is fixedly installed in the installation cavity 11, and its relative position does not change. The multiple mass blocks 32 of the rotating part 3 are combined as a whole, and the multiple mass blocks 32 as a whole are an eccentric mass block that moves synchronously.

[0095] It can be understood that when the rotor motor is driven, the rotating part 3 rotates rapidly around the rotating shaft 21. When the rotating part 3 moves to two extreme motion positions (that is, abutting against the first side wall 12 or the second side wall 13), it collides with the corresponding first side wall 12 or second side wall 13 of the shell 1 respectively. When the rotating part 3 collides with the first side wall 12 or the second side wall 13 of the shell 1, a rapid braking effect is generated, so that the shell 1 receives a corresponding impact tactile sensation. By driving a plurality of driving members 2 in combination, the effects of two extreme states can be achieved, namely, the relative impact motion vibration is canceled on one side and the linear unidirectional tactile sensation on the other side. Then, a fast, multi-frequency linear unidirectional tactile sensation experience is generated by long-term, high-frequency driving.

[0096] In this embodiment, in the state of motion cancellation, the two impact forces generated by the two rotating parts 3 on the housing 1 coincide with the line connecting the centers of mass of the two rotating parts 3, so that the housing 1 is subjected to two forces of equal magnitude and opposite directions, thereby achieving the effect of motion impact cancellation. In another state, the impact forces of the two rotating parts 3 on the housing 1 are parallel to each other and have equal force arms, thereby achieving the effect of a single-direction touch on a simple straight line.
