Description

[Technical Field]

[0001] The present disclosure relates to the technical field of vibration devices, and more particularly to an exciter and an electronic device to which the exciter is applied. [Background technology]

[0002] Conventional vibration devices create the illusion of a force acting in a certain direction by constantly generating asymmetric vibrations, which are called anisotropic vibrations.

[0003] Currently, there are two methods for achieving this force sensation. One is to input an asymmetric signal into a linear resonator to create an illusion using human perception. This method can only generate a continuous, directional force sensation and cannot achieve discrete vibration output. At the same time, the equivalent force felt with this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to achieve a clear sense of direction. The other method generates a strong force sensation by rapidly braking the linear resonator. This method is characterized by the ability to generate highly asymmetric vibrations, a small proportion of extra vibrations, and a distinct, individual force sensation. However, this method requires independent vibration and braking units, and requires constant movement of the vibration unit and braking unit to switch between the energy storage state and the braking state. This makes high-speed continuous operation impossible and requires a complex device structure. Summary of the Invention [Problem to be solved by the invention]

[0024] Conventional vibration devices create the illusion of a force acting in a certain direction by constantly generating asymmetric vibrations, which are called anisotropic vibrations.

[0025] Currently, there are two methods for achieving this force sensation. One is to input an asymmetric signal into a linear resonator to create an illusion using human perception. This method can only generate a continuous, directional force sensation and cannot achieve discrete vibration output. At the same time, the equivalent force felt with this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to achieve a clear sense of direction. The other method generates a strong force sensation by rapidly braking the linear resonator. This method is characterized by the ability to generate highly asymmetric vibrations, a small proportion of extra vibrations, and a distinct, individual force sensation. However, this method requires independent vibration and braking units, and requires constant movement of the vibration unit and braking unit to switch between the energy storage state and the braking state. This makes high-speed continuous operation impossible and requires a complex device structure.

[0026] Based on the above ideas and problems, the present disclosure proposes an exciter 100. As can be understood, the exciter 100 is applied to electronic devices, which may be a tactile display, a tactile interface, a force feedback device, a vibrating feeder, a beauty product, a personal hygiene product, a personal entertainment product, a personal massage device, a tree harvester, an earthquake vibrator, etc. For example, but not limited to, a wireless controller for a game, a mobile motion controller for a sports game, a wireless steering wheel, a remote controller for a sports game on a game console, etc.

[0027] 1 to 4, in an embodiment of the present disclosure, the exciter 100 includes a housing 1, a plurality of driving members 2, and a plurality of rotating units 3, the housing 1 has a mounting cavity 11 and a first side wall 12, the plurality of driving members 2 are installed in the mounting cavity 11 at intervals, the number of driving members 2 is even, at least one rotating unit 3 is connected to the output end of each driving member 2 and is installed eccentrically, the number of rotating units 3 is even, and the two driving members 2 drive the two rotating units 3 in synchronous rotation so that the two rotating units 3 collide with the first side wall 12 at the same time.

[0028] In this embodiment, the housing 1 of the exciter 100 is used to mount, fix, and protect components such as the driving member 2 and the rotating unit 3, i.e., the housing 1 provides a mounting structure for components such as the driving member 2 and the rotating unit 3. As can be understood, the housing 1 may be a mounting shell, a mounting box, a case body, or other structure, and is not limited thereto. The housing 1 has a mounting cavity 11 for arranging and mounting components such as the driving member 2 and the rotating unit 3, and the mounting cavity 11 may be a sealed cavity, or of course, the mounting cavity 11 may be an open cavity.

[0029] As can be understood, the housing 1 may have an integral structure or a divided structure. To facilitate easy attachment and detachment of components such as the driving member 2 and the rotating unit 3, the housing 1 may be selectively installed as separate bodies. That is, the housing 1 includes a first housing and a second housing, which are butt-connected to each other and surround the mounting cavity 11. The housing 1 may have a regular shape such as a circle, an ellipse, a rectangle, a triangle, or other polygon, or may have other irregular shapes, and is not limited thereto.

[0030] In this embodiment, the housing 1 has a first side wall 12. The first side wall 12 may be an outer wall of the housing 1 or a side wall or partition structure installed in the mounting cavity 11 of the housing 1, and is not limited thereto. Optionally, the housing 1 is installed in a square shape. Furthermore, the housing 1 may be optionally a rectangular structure. The first side wall 12 may be optionally a bottom wall of the housing 1. The housing 1 further has two vertical side walls connected to the first side wall 12, the two vertical side walls being located at both ends of the first side wall 12. In this case, half of the multiple drive members 2 are installed adjacent to one vertical side wall, and the other half are installed adjacent to the other vertical side wall.

[0031] As can be seen, the number of drive members 2 in one half corresponds to the number of drive members 2 in the other half, and they are arranged symmetrically with respect to a center line perpendicular to the first side wall 12. In this embodiment, the drive members 2 and the rotating unit 3 are fitted together to form a rotating assembly. Each drive member 2 may have one output end or two output ends. When the drive member 2 has two output ends, the two output ends are located on the axis of the drive member 2. Optionally, each rotating unit 3 is connected to the output end of the drive member 2 and arranged eccentrically.

[0032] In this embodiment, the driving member 2 may be fixed directly to the inner wall of the housing 1, or may be mounted in the first mounting cavity 11 by other structures such as a bracket or a mounting seat. As can be understood, the rotating part 3 may have an eccentric structure, and when one end of the rotating part 3 is connected to the output end of the driving member 2 and the driving member 2 thereby drives the rotating part 3 to rotate, the rotating part 3 moves circumferentially around the output end of the driving member 2, i.e., the position where the rotating part 3 is connected to the output end of the driving member 2 may be located at an eccentric position of the structure of the rotating part 3 itself (the position where the rotating part 3 is connected to the output end of the driving member 2 does not overlap with the center of the rotating part 3).

[0033] As can be understood, by simultaneously controlling multiple driving members 2 to rotate multiple rotating parts 3, when multiple rotating parts 3 collide with the first side wall 12 or the vertical side wall at the same time, i.e., when multiple rotating parts 3 collide with the first side wall 12 at the same time, the exciter 100 creates a sense of force in a single linear direction, and when multiple rotating parts 3 collide with a vertical side wall at the same time, the multiple rotating parts 3 generate forces of the same magnitude but in opposite directions on the vertical side wall to cancel each other out, and the exciter 100 obtains a sense of force in a single linear direction.

[0034] It should be noted that the exciter 100 further includes a controller or control structure, which can simultaneously control a plurality of drive members 2 to rotationally drive a plurality of rotating parts 3. As can be understood, the controller or control structure may be an individual controller or a remote control, or may be a structure such as a control circuit or control button integrated in the exciter 100, and is not limited thereto.

[0035] The exciter 100 of the present disclosure forms a mounting cavity 11 within the housing 1, and uses the mounting cavity 11 to mount, fix, and protect the driving member 2 and the rotating unit 3. A plurality of driving members 2 are installed at intervals within the mounting cavity 11, and the number of driving members 2 is an even number. At least one rotating unit 3 among the plurality of rotating units 3 is connected to the output end of each driving member 2 and is installed eccentrically, and the number of rotating units 3 is an even number. By controlling the plurality of driving members 2 to drive the plurality of rotating units 3 in synchronous rotation, the plurality of rotating units 3 are used to simultaneously collide with the first side wall 12, and the exciter 100 generates a force in a single linear direction. At the same time, the exciter 100 uses the plurality of driving members 2 to respectively drive the rotation structures of the plurality of rotating units 3 that are installed eccentrically. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a strong and clear force in a single linear direction.

[0036] In one embodiment, a second side wall 13 is further installed on the housing 1, one end of the second side wall 13 is connected to the first side wall 12, and the mounting cavity 11 is divided into a first cavity 111 and a second cavity 112, a portion of the driving member 2 is installed in the first cavity 111, and a portion of the driving member 2 is installed 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, and here, the multiple driving members 2 drive the multiple rotating parts 3 in synchronization with each other so that the multiple rotating parts 3 collide with the first side wall 12 or the second side wall 13 simultaneously.

[0037] In this embodiment, as shown in Figures 1 to 4, a second side wall 13 is installed in the mounting cavity 11 of the housing 1, with one end of the second side wall 13 connected to the first side wall 12 and dividing the mounting cavity 11 into a first cavity 111 and a second cavity 112. As can be understood, the first cavity 111 and the second cavity 112 may be closed cavities spaced apart from each other, open cavities, or cavities communicating with each other, and this is not limited thereto. 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 the first side wall 12.

[0038] Alternatively, the housing 1 may be rectangular. In this embodiment, the second side wall 13 is perpendicular to the first side wall 12 and connected to the midpoint of the first side wall 12. That is, the second side wall 13 equally divides the mounting cavity 11 such that the first cavity 111 and the second cavity 112 are symmetrically arranged with respect 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.

[0039] Of course, in other embodiments, the second side wall 13 does not have to be perpendicular to the first side wall 12. For example, when the rotating unit 3 is arranged in a fan shape, if the driving member 2 rotates the rotating unit 3 by 90° and hits the first side wall 12 or the second side wall 13, the first side wall 12 and the second side wall 13 do not have to be perpendicular to each other, and this is not a limitation. As can be understood, the first side wall 12 may be configured as a two-stage structure arranged at an angle, in which case the second side wall 13 is connected to the corner of the first side wall 12, and in this case the second side wall 13 is not perpendicular to at least one portion of the first side wall 12, and this is not a limitation.

[0040] In this embodiment, half of the plurality of drive members 2 are installed in the first cavity 111 and the other half are installed in the second cavity 112, so that the number of half of the drive members 2 matches the number of the other half of the drive members 2 and they are installed symmetrically with respect to the second side wall 13. As can be understood, half of the plurality of drive members 2 are installed adjacent to a vertical side wall and the other half of the drive members 2 are installed adjacent to another vertical side wall, or the plurality of drive members 2 in the first cavity 111 are installed adjacent to the second side wall 13 and the drive members 2 in the second cavity 112 are installed adjacent to the second side wall 13, or some of the plurality of drive members 2 in the first cavity 111 are installed adjacent to the vertical side wall. The number of drive members 2 in the first cavity 111 is the same as the number of drive members 2 in the second cavity 112, and some of the drive members 2 are installed adjacent to the second side wall 13; among the multiple drive members 2 in the second cavity 112, some of the drive members 2 are installed adjacent to another vertical side wall, and some of the drive members 2 are installed adjacent to the second side wall 13; it is only necessary to ensure that the number of drive members 2 in the first cavity 111 is the same as the number of drive members 2 in the second cavity 112 and that they are installed symmetrically with respect to the second side wall 13, and this is not limited thereto.

[0041] As can be understood, when multiple driving members 2 are controlled simultaneously to rotate multiple rotating parts 3, and the multiple rotating parts 3 collide with the first side wall 12 or the second side wall 13 / vertical side wall simultaneously, i.e., when the multiple rotating parts 3 collide with the first side wall 12 simultaneously, the exciter 100 creates a sense of force in a single linear direction, and when the multiple rotating parts 3 collide with the second side wall 13 / vertical side wall simultaneously, the multiple rotating parts 3 generate forces of the same magnitude but in the opposite direction on the second side wall 13 / vertical side wall to cancel each other out, and the exciter 100 obtains a sense of force in a single linear direction.

[0042] In one embodiment, as shown in Figures 1, 3 and 4, the driving member 2 includes two, the rotating unit 3 includes two, one driving member 2 is installed in the first cavity 111, another driving member 2 is installed in the second cavity 112, and each rotating unit 3 is connected to the output end of the driving member 2.

[0043] In this embodiment, as shown in FIG. 3, two driving members 2 are controlled simultaneously to rotate two rotating parts 3, and the two rotating parts 3 collide with the first side wall 12 at the same time, thereby creating a sense of force in a single linear direction on the housing 1 of the exciter 100. As shown in FIG. 4, two driving members 2 are controlled simultaneously to rotate two rotating parts 3, and the two rotating parts 3 collide with the second side wall 13 at the same time, causing the two rotating parts 3 to generate equal but opposite forces on the second side wall 13, which cancel each other out. This ensures the sense of force that the two rotating parts 3 simultaneously collide with the first side wall 12, and the exciter 100 can generate a strong and clear sense of force in a single linear direction.

[0044] As can be understood, the exciter 100 is defined as having a first state in which the two driving members 2 are simultaneously controlled to rotate the two rotating parts 3 and cause the two rotating parts 3 to collide with the first side wall 12 at the same time, and a second state in which the two driving members 2 are simultaneously controlled to rotate the two rotating parts 3 and cause the two rotating parts 3 to collide with the second side wall 13 at the same time. As shown in FIG. 5, when an acceleration sensor is used to detect vibration of the exciter 100, in the first state, there is a clear downward vibration sensation and a unidirectional tactile sensation in the housing 1 of the exciter 100, and in the second state, there is substantially no vibration sensation in the housing 1 of the exciter 100.

[0045] The exciter 100 of the present disclosure forms a mounting cavity 11 in a housing 1, and uses the mounting cavity 11 to mount, fix, and protect the driving member 2 and the rotating unit 3. A second side wall 13 is installed in the mounting cavity 11 of the housing 1, whereby one end of the second side wall 13 is connected to the first side wall 12. The mounting cavity 11 is divided into a first cavity 111 and a second cavity 112, and the first cavity 111 and the second cavity 112 are used to mount the driving member 2 and the rotating unit 3, respectively. Each rotating unit 3 is connected to the output end of the driving member 2 and is installed eccentrically, so that when the two driving members 2 are controlled to drive the two rotating units 3 in rotation synchronously, the two rotating units 3 can be driven synchronously. When the rotating parts 3 collide with the first side wall 12 or the second side wall 13 simultaneously, i.e., when the two rotating parts 3 collide with the first side wall 12 at the same time, the exciter 100 generates a force in a single linear direction. When the two rotating parts 3 collide with the second side wall 13 at the same time, the two rotating parts 3 generate equal but opposite forces on the second side wall 13, which cancel each other out, so that the exciter 100 generates a force in a single linear direction. At the same time, the exciter 100 uses two driving members 2 to respectively drive the rotation structures of the two rotating parts 3 that are installed eccentrically. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a strong and clear force in a single linear direction.

[0046] In one embodiment, as shown in Figures 1 to 4, each driving member 2 is a rotor motor in which a rotating shaft 21 is installed, and a shaft hole 31 is installed in each rotating part 3, the shaft hole 31 is installed eccentrically in the rotating part 3, and the rotating shaft 21 is drilled within the shaft hole 31.

[0047] As can be understood, the structure of the rotating part 3 may be a regular shape or an irregular shape. Optionally, the shape of the rotating part 3 may be a circle, an ellipse, a square, a triangle, or a polygon. The shaft hole 31 does not overlap with the center of the shape of the rotating part 3. Of course, the shape of the rotating part 3 may be an irregular shape and is not limited here.

[0048] In this embodiment, the driving member 2 is configured as a rotor motor, and the rotor motor is used to drive the rotating structure of the eccentrically installed rotating part 3. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a powerful and clear sense of force.

[0049] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in a single linear direction. Two sets of rotating assemblies, each consisting of a driving member 2 and a rotating unit 3, are symmetrically installed in the first cavity 111 and the second cavity 112. Optionally, the weights of the rotating units 3 are the same. The shape contours of the rotating units 3 are the same.

[0050] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in a single linear direction. The driving frequencies of the multiple driving members 2 are the same. The driving voltages of the multiple driving members 2 are the same.

[0051] In one embodiment, each rotating part 3 includes at least one mass block 32. As can be understood, the material of the mass block 32 can be a metallic material, i.e., the mass block 32 is made of a metallic material. Of course, the mass block 32 can also be a non-metallic material, i.e., the mass block 32 is made of a non-metallic material.

[0052] In order to generate a strong and clear force in the exciter 100, the mass block 32 of the rotating unit 3 is made of a relatively heavy structure, and optionally, the mass block 32 is made of a metal material. To further increase the mass of the rotating unit 3, the rotating unit 3 can have a counterweight or multiple mass blocks 32 installed on the mass block 32, and the counterweight or multiple mass blocks 32 are located radially or circumferentially around the rotation center of the rotating unit 3, and the shaft hole 31 is located at an eccentric position of the entire rotating unit 3 (i.e., the shaft hole 31 does not overlap with the center of the entire rotating unit 3).

[0053] In one embodiment, as shown in FIG. 2 , each rotating unit 3 includes three mass blocks 32, one mass block 32 connected to the output end of the driving member 2 and eccentrically installed, and the other two mass blocks 32 connected sequentially along the radial direction of the rotating unit 3, or the other two mass blocks 32 connected sequentially along the circumferential direction of the mass blocks 32.

[0054] 1 to 4, the number of mass blocks 32 in each rotating unit 3 may be one, two, three, four, or more, and is not limited thereto. Among the multiple mass blocks 32, the shaft hole 31 on the mass block 32 connected to the rotation shaft 21 of the drive member 2 is located at an eccentric position of the mass block 32, and in this case, another mass block 32 is connected to the mass block 32 in the radial or circumferential direction, 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.

[0055] Of course, the axial hole 31 may be located at the center of the mass block 32, in which case another mass block 32 is connected to one side of the mass block 32, so that the entire rotating part 3 has an eccentric structure, which is not limited here.

[0056] 3 and 4 , each drive member 2 is disposed adjacent to a connection point between the first side wall 12 and the second side wall 13, and the two drive members 2 are disposed symmetrically with respect to the second side wall 13. As can be seen, the first cavity 111 and the second cavity 112 are disposed symmetrically with respect to the second side wall 13. Optionally, the first cavity 111 and the second cavity 112 are disposed in a square shape. When the number of drive members 2 is plural and is an even number, the plurality of drive members 2 in the first cavity 111 and the plurality of drive members 2 in the second cavity 112 are disposed symmetrically with respect to the second side wall 13.

[0057] Of course, in other embodiments, the plurality of drive members 2 in the first cavity 111 are arranged at intervals along the connection point between the first side wall 12 and the second side wall 13, and the plurality of drive members 2 in the second cavity 112 are arranged at intervals along the connection point between the first side wall 12 and the second side wall 13, i.e., the plurality of drive members 2 are arranged at intervals along the extending longitudinal direction of the second side wall 13, and / or the plurality of drive members 2 in the first cavity 111 are arranged at intervals along the connection point between the first side wall 12 and the vertical side wall, and the plurality of drive members 2 in the second cavity 112 are arranged at intervals along the connection point between the first side wall 12 and the vertical side wall, i.e., the plurality of drive members 2 are arranged at intervals along the extending longitudinal direction of the vertical side wall, and the embodiments are not limited thereto.

[0058] In one embodiment, the driving member 2 includes two, the rotating portion 3 includes two, one driving member 2 is installed in the first cavity 111, another driving member 2 is installed in the second cavity 112, each rotating portion 3 is connected to the output end of the driving member 2, and when the two rotating portions 3 are defined as colliding with the first side wall 12 simultaneously, the two rotating portions 3 each form a first impact point 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.

[0059] In this embodiment, as shown in Fig. 3, this is to ensure that the distances from the two first impact points 121 formed when the two rotating units 3 simultaneously collide with the first side wall 12 to the second side wall 13 are the same. The output end of each driving member 2 (i.e., the rotation center of the rotating unit 3) is located on the bisector of the angle formed by the first side wall 12 and the second side wall 13, so that the exciter 100 can align the force sensation generated in a single linear direction and improve the user's experience.

[0060] In one embodiment, the driving member 2 includes two, the rotating portion 3 includes two, one driving member 2 is installed in the first cavity 111, and another driving member 2 is installed in the second cavity 112, each rotating portion 3 is connected to the output end of the driving member 2, and when the two rotating portions 3 collide with the second side wall 13 simultaneously, the two rotating portions 3 form second impact points 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.

[0061] In this embodiment, as shown in FIG. 4 , to ensure that the distances from the two second impact points 131 formed when the two rotating parts 3 simultaneously collide with the second side wall 13 to the first side wall 12 are the same, i.e., the two second impact points 131 overlap the second side wall 13, and the forces formed when the two rotating parts 3 simultaneously collide with the second side wall 13 cancel each other out, thereby ensuring that the exciter 100 can generate a strong and clear force in a single linear direction and improving the user experience, the output end of each driving member 2 (i.e., 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.

[0062] 1, 3, and 4, the angle by which each driving member 2 rotates the rotating unit 3 is 90°. As can be seen, optionally, the second side wall 13 of the housing 1 is disposed perpendicular to the first side wall 12, and the second side wall 13 is connected to the midpoint of the first side wall 12. Each driving member 2 is disposed adjacent to the connection point between the first side wall 12 and the second side wall 13. Optionally, the driving member 2 is located diagonally across the angle between the first side wall 12 and the second side wall 13.

[0063] As can be seen, the rotating part 3 is located on the opposite side of the angle formed by the first side wall 12 and the second side wall 13 of the driving member 2, so that when the driving member 2 drives the rotating part 3 to rotate by 90 degrees, the rotating part 3 collides with the first side wall 12 or the second side wall 13.

[0064] Of course, the angle by which each driving member 2 rotates the rotating unit 3 may be greater than or less than 90°. Note that, when the connecting line between the rotation axis 21 of the driving member 2 and the center of the rotating unit 3 is not parallel to the first side wall 12 or the second side wall 13, the angle by which the driving member 2 rotates the rotating unit 3 may be greater than or less than 90° and is not limited here.

[0065] As can be understood, when two rotating parts 3 collide with the first side wall 12 at the same time, the connecting line between the rotation 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 two rotating parts 3 collide with the second side wall 13 at the same time, the connecting line between the rotation axis 21 of the driving member 2 and the center of the rotating part 3 is not parallel to the second side wall 13, in this case, the angle at which the driving member 2 rotates the rotating part 3 may be greater than 90° or less than 90°, and is not limited here.

[0066] In this embodiment, as shown in Fig. 3, when a driving member 2 drives a rotating unit 3 to rotate in the forward direction, i.e., the driving member 2 rotates in the forward direction, and another driving member 2 drives a rotating unit 3 to rotate in the reverse direction, i.e., the driving member 2 rotates in the reverse direction, as defined in the present embodiment, and when the two driving members 2 drive the two rotating units 3 to rotate, the two rotating units 3 simultaneously collide with the first side wall 12. As shown in Fig. 4, when a driving member 2 drives a rotating unit 3 to rotate in the reverse direction, i.e., the driving member 2 rotates in the reverse direction, as defined in the present embodiment, and when the two driving members 2 drive the two rotating units 3 to rotate, the two rotating units 3 simultaneously collide with the second side wall 13.

[0067] In one embodiment, when the rotating part 3 is defined as colliding with the first side wall 12 or the second side wall 13, a collision point is formed on the first side wall 12 and the second side wall 13, and the exciter 100 further includes a buffer part 4, which is installed on the first side wall 12 and / or the second side wall 13 and located at the collision point, or when the buffer part 4 is installed on the rotating part 3 and the drive member 2 drives the rotating part 3 to rotate, the buffer part 4 abuts against the collision point.

[0068] In this embodiment, as shown in Figures 1 to 4, by installing the buffer unit 4, the impact force of the rotating unit 3 can be adjusted and buffered using the buffer unit 4, and the sensitive frequency of the vibration wave can be adjusted using the buffer unit 4, thereby making the tip of the peak in Figure 5 sharper, and the buffer unit 4 also has a noise reduction effect.

[0069] As can be understood, when the rotating unit 3 collides with the first side wall 12 or the second side wall 13, a collision point is formed on the first side wall 12 and the second side wall 13, and the collision point coincides with the first impact point 121 and the second impact point 131. In this embodiment, the buffer unit 4 may be installed on the first side wall 12 and / or the second side wall 13 of the housing 1, and may be located at the first impact point 121 and / or the second impact point 131. Of course, the buffer unit 4 may also be installed on the rotating unit 3, so that when the drive member 2 drives the rotating unit 3 to rotate, the buffer unit 4 abuts against the first impact point 121 and / or the second impact point 131.

[0070] In this embodiment, the buffer unit 4 includes a plurality of buffer units 4, and the plurality of buffer units 4 are respectively installed on the first side wall 12 and the second side wall 13. Alternatively, the plurality of buffer units 4 are installed on opposite sides of the rotating unit 3, so that when the rotating unit 3 collides with the first side wall 12, the first side wall 12 abuts against the buffer units 4, or when the rotating unit 3 collides with the second side wall 13, the second side wall 13 abuts against the buffer units 4, etc., this is not limited here.

[0071] Alternatively, the buffer 4 may be made of a compressible material such as foam, sponge, rubber mat, etc., but is not limited thereto. That is, the buffer 4 does not use a rigid material.

[0072] In this embodiment, the driving member 2 is fixedly mounted in the mounting cavity 11, and the multiple mass blocks 32 of the rotating part 3 are combined together without changing their relative positions, and the entire multiple mass blocks 32 are eccentric mass blocks that move synchronously.

[0073] As can be seen, when the rotor motor is driven, the rotating unit 3 rapidly rotates around the rotation axis 21. When the rotating unit 3 moves to one of two extreme movement positions (i.e., abutting against the first side wall 12 or the second side wall 13), it collides with the corresponding first side wall 12 or the second side wall 13 of the housing 1, respectively. When the rotating unit 3 collides with the first side wall 12 or the second side wall 13 of the housing 1, a rapid braking effect occurs, causing the housing 1 to experience a corresponding impact sensation. By driving multiple driving members 2 in combination, two extreme state effects can be achieved: on one side, opposing impact motion vibrations cancel each other out, and on the other side, a linear, unidirectional tactile sensation is experienced. Furthermore, long-term, high-frequency driving can be used to generate a rapid, multi-frequency, linear, unidirectional tactile sensation experience.

[0074] In this embodiment, in the motion cancellation state, the two impact forces generated by the two rotating parts 3 on the housing 1 overlap the connecting line of the centers of mass of the two rotating parts 3, so that the housing 1 receives two equal but opposite acting forces, thereby realizing 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 the force arms are equal, so that the effect of a simple linear one-way tactile sensation is realized.
