Description

Technical Field

[0001] The present disclosure relates to the technical field of vibration devices, and in particular, to exciters and electronic devices applying such exciters.

Background Art

[0002] Conventional vibration devices constantly generate asymmetric vibrations to create the illusion of a force acting "as if in a certain direction", and such vibrations are called anisotropic vibrations.

[0003] Currently, there are two means to achieve such a sense of force. One is to input an asymmetric signal into a linear resonator and utilize the human sense to create an illusion. In principle, this method can only generate a continuous directional sense of force and cannot achieve discrete vibration output. At the same time, the equivalent force felt by this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to obtain a distinct sense of direction. The other is to rapidly brake a linear resonator to generate a strong sense of force. This method can generate vibrations with a large degree of asymmetry and has the characteristics that the proportion of extra vibrations is small and the sense of force is distinct by itself. However, this method is independently configured in the vibration part and the braking part respectively, and it is necessary to constantly move the vibration part and the braking part to switch between the energy storage state and the braking state, making high-speed continuous operation impossible and the device structure complex.

[0004] However, such a device is only capable of realizing vibrations in a linear direction and cannot generate a sense of force in the rotational direction.

[0024] Conventional vibration devices constantly generate asymmetric vibrations, creating the illusion of a force acting "as if it were moving in a certain direction." Such vibrations are called anisotropic vibrations.

[0025] Currently, there are two methods for realizing this sense of force. One is to input an asymmetric signal into a linear resonator and use human perception to create an illusion. This method, in principle, can only generate a sustained directional sense of force and cannot realize discrete vibration output. At the same time, the equivalent force felt with this method is small, and the asymmetric signal also generates extraneous vibrations, making it difficult to obtain a clear sense of direction. The other method generates a strong sense of force by rapidly damping a linear resonator. This method can generate vibrations with a high degree of asymmetry, and has the advantage of a small proportion of extraneous vibrations and a clear, independent sense of force. However, this method requires the vibration part and the damping part to be configured independently, and it is necessary to constantly move the vibration part and the damping part to switch between the energy storage state and the damping state, making high-speed continuous operation impossible and resulting in a complex device structure.

[0026] However, such devices are limited to generating linear vibrations and cannot generate rotational force.

[0029] In this embodiment, the housing 1 of the exciter 100 is used to mount, secure, and protect components such as the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5; that is, the housing 1 provides a mounting structure for components such as the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5. To make it clear, the housing 1 may be, but is not limited to, a mounting shell, mounting box, or case body. The housing 1 has a mounting cavity 11 for arranging and mounting components such as the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5, and the mounting cavity 11 may be a sealed cavity, or of course, an open cavity.

[0030] To ensure clarity, the housing 1 may be a single, integrated structure or a segmented structure. To facilitate the attachment and detachment of components such as the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5, the housing 1 may be selectively installed as a separate component. That is, the housing 1 includes the first housing and the second housing, which are butt-jointed and connected to form a mounting cavity 11. The housing 1 may have a regular shape such as a circle, ellipse, square, triangle, or other polygon, or it may have other irregular shapes, and is not limited thereto.

[0031] In this embodiment, in order to generate a rotational force in the exciter 100, the housing 1 has a first side wall 12 and a second side wall 13 that are installed opposite each other. The first side wall 12 and the second side wall 13 may be the outer walls of the housing 1, or they may be side walls or partition plate structures installed within the mounting cavity 11 of the housing 1, and are not limited thereto. By installing the first partition plate 14 and the second partition plate 15 within the mounting cavity 11 of the housing 1, both ends of the first partition plate 14 are connected to the first side wall 12 and the second side wall 13, respectively, and by dividing the mounting cavity 11 into the first cavity 111 and the second cavity 112, the first rotating assembly 2 and the fourth rotating assembly 5 are mounted and fixed using the first cavity 111, the second partition plate 15 is installed within the second cavity 112, and one end of the second partition plate 15 is connected to the first partition plate 14, and the second cavity 112 is divided into the first sub-cavity 1121 and the second sub-cavity The cavity is divided into two parts, so that the first subcavity 1121 is located on one side closer to the second side wall 13, and the second subcavity 1122 is located on the other side closer to the first side wall 12. In other words, the second partition plate 15, the first partition plate 14, and the second side wall 13 surround the first subcavity 1121, and the second partition plate 15, the first partition plate 14, and the first side wall 12 surround the second subcavity 1122. The second rotating assembly 3 is attached and fixed using the first subcavity 1121, and the third rotating assembly 4 is attached and fixed using the second subcavity 1122.

[0032] Selectively, the housing 1 is installed in a rectangular shape. Furthermore, the housing 1 may selectively have a square or rectangular structure. In this embodiment, the first rotating assembly 2 and the second rotating assembly 3 are close to the second side wall 13, and the fourth rotating assembly 5 and the third rotating assembly 4 are close to the first side wall 12.

[0033] In this embodiment, the first rotating assembly 2 includes a first drive member 21 and a first rotating part 22, the first drive member 21 being installed in the first cavity 111, and the first drive member 21 may be directly fixed to the inner wall of the housing 1 or attached to the first cavity 111 by other structures such as brackets or mounting seats. The second rotating assembly 3 includes a second drive member 31 and a second rotating part 32, the second drive member 31 being installed in the first sub-cavity 1121, the second drive member 31 may be directly fixed to the inner wall of the housing 1 or attached to the first sub-cavity 1121 by other structures such as brackets or mounting seats. The third rotating assembly 4 includes a third drive member 41 and a third rotating part 42, the third drive member 41 being installed in the second subcavity 1122, and the third drive member 41 may be directly fixed to the inner wall of the housing 1 or mounted in the second subcavity 1122 by other structures such as brackets or mounting seats. The fourth rotating assembly 5 includes a fourth drive member 51 and a fourth rotating part 52, the fourth drive member 51 being installed in the first cavity 111 and spaced apart from the first drive member 21, the fourth drive member 51 may be directly fixed to the inner wall of the housing 1 or mounted in the first cavity 111 by other structures such as brackets or mounting seats. Optionally, the first rotating assembly 2 is installed close to the second side wall 13, and the fourth rotating assembly 5 is installed close to the first side wall 12.

[0034] In this embodiment, the first rotating part 22, the second rotating part 32, the third rotating part 42, and the fourth rotating part 52 are connected to the output terminals of the first drive member 21, the second drive member 31, the third drive member 41, and the fourth drive member 51, respectively, and are installed eccentrically. To make it easier to understand, the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may have an eccentric structure, and one end of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 is connected to the output terminal of the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51, thereby the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51 rotationally drives the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 1 / The first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 rotate around the output end of the fourth driving member 51, that is, the position where the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 are connected to the output end of the first driving member 21 / second driving member 31 / third driving member 41 / fourth driving member 51 is located at an eccentric position of the structure of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 itself (the position where the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 are connected to the output end of the first driving member 21 / second driving member 31 / third driving member 41 / fourth driving member 51 does not coincide with the center of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52).

[0035] In this embodiment, the structures of the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5 are the same or similar; that is, the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4, and the fourth rotating assembly 5 all include a drive member structure and a rotating part structure, and the rotating part structure is connected to the output end of the drive member structure and is installed eccentrically. To make it clear, the rotating part structure itself may be an eccentric structure, and when one end of the rotating part structure is connected to the output end of the drive member structure, and the drive member structure rotates the rotating part structure thereafter, the rotating part structure may move circumferentially around the output end of the drive member structure, that is, the output end of the drive member structure may be located at an eccentric position of the structure of the rotating part structure itself.

[0036] In this embodiment, the exciter is made to have a clockwise rotational tactile sensation by controlling the operation of the first rotational assembly 2 and the second rotational assembly 3, and the exciter is made to have a counterclockwise rotational tactile sensation by controlling the operation of the third rotational assembly 4 and the fourth rotational assembly 5. As can be understood, the exciter 100 can generate two unidirectional rotational tactile sensations on the same coordinate axis at high speed and multi-frequency by utilizing long-duration, high-frequency drive, that is, the exciter 100 can generate clockwise and counterclockwise rotational tactile sensations.

[0037] To make it easier to understand, by simultaneously controlling the first drive member 21 and the second drive member 31 to drive the first rotating part 22 and the second rotating part 32 in synchronous motion, the effects of two extreme positions can be achieved by having the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively, or by having the first rotating part 22 and the second rotating part 32 simultaneously collide with the first partition plate 14, that is, the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 1 When the first rotating part 32 and the second rotating part 32 collide with the first partition plate 14, a torque can be generated in the clockwise rotational direction, thereby enabling the exciter 100 to generate a force in the clockwise rotational direction, that is, to form a unidirectional rotational sensation. When the first rotating part 22 and the second rotating part 32 collide with the first partition plate 14 simultaneously, forces of the same magnitude but opposite directions are generated and cancel each other out, thereby ensuring that the exciter 100 can generate a force in the unidirectional rotational direction.

[0038] Of course, by simultaneously controlling the third drive member 41 and the fourth drive member 51 to drive the third rotating part 42 and the fourth rotating part 52 in synchronous motion, the effects of two extreme positions can be achieved by having the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12, respectively, or by having the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first partition plate 14, that is, the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and When the third rotating part 42 and the fourth rotating part 52 collide with the first partition plate 14, a torque can be generated in the counterclockwise rotational direction, thereby enabling the exciter 100 to generate a counterclockwise rotational force, that is, to form a unidirectional rotational sensation. When the third rotating part 42 and the fourth rotating part 52 collide with the first partition plate 14 simultaneously, forces of the same magnitude but opposite directions are generated and cancel each other out, thereby ensuring that the exciter 100 can generate a unidirectional rotational force.

[0039] At the same time, by setting the first rotating assembly 2 / second rotating assembly 3 / third rotating assembly 4 / fourth rotating assembly 5 as the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51, and driving the rotational structure of the eccentrically installed first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52, the structure of the exciter 100 is not only effectively simplified, but the exciter 100 can achieve high-speed continuous operation and generate a powerful and clear sense of force.

[0040] The exciter 100 further includes a controller or control structure, which can control the first drive member 21 and the second drive member 31 to rotationally drive the first rotating part 22 and the second rotating part 32, or the controller or control structure can control the third drive member 41 and the fourth drive member 51 to rotationally drive the third rotating part 42 and the fourth rotating part 52. To make it clear, the controller or control structure may be an individual controller or remote control, or a control circuit or control button structure integrated into the exciter 100, and is not limited thereto.

[0041] In this embodiment, as shown in Figures 3 to 6, the first rotating assembly 2 and the second rotating assembly 3 are located between the second side wall 13 and the extension line of the second partition plate 15, and the third rotating assembly 4 and the fourth rotating assembly 5 are located between the first side wall 12 and the extension line of the second partition plate 15.

[0042] As shown in Figure 3, by controlling the first drive member 21 and the second drive member 31 to rotate in the forward direction so that the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively, and by rotating the first rotating part 22 and the second rotating part 32 clockwise, torque is generated in the clockwise direction, thereby enabling the exciter 100 to generate a force in the clockwise rotation direction. As shown in Figure 4, by controlling the first drive member 21 and the second drive member 31 to rotate in the reverse direction so that the first rotating part 22 and the second rotating part 32 simultaneously collide with the first partition plate 14, and by rotating the first rotating part 22 and the second rotating part 32 counterclockwise, opposing forces of the same magnitude are generated in the counterclockwise direction and cancel each other out, thereby ensuring that the exciter 100 can generate a force in the clockwise rotation direction in one direction.

[0043] As shown in Figure 5, by controlling the third drive member 41 and the fourth drive member 51 to rotate in the forward direction so that the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first side wall 12 and the second partition plate 15, respectively, and by rotating the third rotating part 42 and the fourth rotating part 52 counterclockwise, torque is generated in the counterclockwise direction, thereby enabling the exciter 100 to generate a force in the counterclockwise rotation direction. As shown in Figure 6, by controlling the third drive member 41 and the fourth drive member 51 to rotate in the reverse direction so that the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first partition plate 14, and by rotating the third rotating part 42 and the fourth rotating part 52 clockwise, opposing forces of the same magnitude are generated in the clockwise direction and cancel each other out, thereby ensuring that the exciter 100 can generate a force in the counterclockwise rotation direction in one direction.

[0044] To make it easier to understand, the exciter 100 is defined to have a first state in which it rotates clockwise and a second state in which it rotates counterclockwise. In the first state, the exciter 100 is defined to have a first position in which the first drive member 21 and the second drive member 31 are controlled to rotate in the forward direction so that the first rotating part 22 and the second rotating part 32 collide simultaneously with the second side wall 13 and the second partition plate 15, respectively, thereby driving the first rotating part 22 and the second rotating part 32 to rotate clockwise, respectively, and a second position in which the first drive member 21 and the second drive member 31 are controlled to rotate in the reverse direction so that the first rotating part 22 and the second rotating part 32 collide simultaneously with the first partition plate 14, thereby driving the first rotating part 22 and the second rotating part 32 to rotate counterclockwise. As shown in Figure 7, when two acceleration sensors are used to detect vibrations of the exciter 100, in the first position in the first state, there is a clear vibration sensation and a clockwise rotational tactile sensation in the housing 1 of the exciter 100, while in the second position in the first state, there is no clear tactile sensation in the housing 1 of the exciter 100. Noise remains due to the limitations of the accuracy of the hand-printed prototype.

[0045] In the second state, the exciter 100 is defined to have a third position in which the third drive member 41 and the fourth drive member 51 are controlled to rotate in the forward direction so that the third rotating part 42 and the fourth rotating part 52 collide simultaneously with the first side wall 12 and the second partition plate 15, respectively, thereby driving the third rotating part 42 and the fourth rotating part 52 to rotate counterclockwise, and a fourth position in which the third drive member 41 and the fourth drive member 51 are controlled to rotate in the reverse direction so that the third rotating part 42 and the fourth rotating part 52 collide simultaneously with the first partition plate 14, thereby driving the third rotating part 42 and the fourth rotating part 52 to rotate clockwise. As shown in Figure 8, when two acceleration sensors are used to detect vibrations of the exciter 100, at the third position in the second state, there is a clear vibration sensation and a clockwise rotational tactile sensation in the housing 1 of the exciter 100, while at the fourth position in the second state, there is no clear tactile sensation in the housing 1 of the exciter 100. Noise remains due to the limitations of the accuracy of the hand-printed prototype.

[0046] In this embodiment, when the exciter 100 is in a first state of clockwise rotation, the controller or control structure controls only the first drive member 21 and the second drive member 31 of the first rotation assembly 2 and the second rotation assembly 3 to rotationally drive the first rotation part 22 and the second rotation part 32, and in this case, the third drive member 41 and the fourth drive member 51 of the third rotation assembly 4 and the fourth rotation assembly 5 are in a power-off state. When the exciter 100 is in a second state of counterclockwise rotation, the controller or control structure controls only the third drive member 41 and the fourth drive member 51 of the third rotation assembly 4 and the fourth rotation assembly 5 to rotationally drive the third rotation part 42 and the fourth rotation part 52, and in this case, the first drive member 21 and the second drive member 31 of the first rotation assembly 2 and the second rotation assembly 3 are in a power-off state.

[0047] In this embodiment, in order to ensure that the controller or control structure controls the first rotation assembly 2 and the second rotation assembly 3 or the third rotation assembly 4 and the fourth rotation assembly 5 to achieve synchronous operation, in the initial state, the first rotation assembly 2 and the second rotation assembly 3 are installed symmetrically with respect to the first partition plate 14 between the second partition plate 15 and the second side wall 13, that is, the first rotation assembly 2 and the second rotation assembly 3 are installed symmetrically with respect to the first partition plate 14 between the second partition plate 15 and the second side wall 13, that is, the third rotation assembly 4 and the fourth rotation assembly 5 are installed symmetrically with respect to the first partition plate 14 between the second partition plate 15 and the first side wall 12, that is, the third rotation assembly 4 and the fourth rotation assembly 5 are installed symmetrically with respect to the left side of the housing 1.

[0048] The exciter 100 of this disclosure has a mounting cavity 11 formed within the housing 1, thereby mounting, fixing and protecting the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5 using the mounting cavity 11, the housing 1 has a first side wall 12 and a second side wall 13 that are installed opposite each other, and by installing a first partition plate 14 and a second partition plate 15 within the mounting cavity 11 of the housing 1, both ends of the first partition plate 14 are connected to the first side wall 12 and the second side wall 13, respectively, and are mounted. The cavity 11 is divided into a first cavity 111 and a second cavity 112, one end of the second partition plate 15 is connected to the first partition plate 14 and is located inside the second cavity 112, so that the second partition plate 15, the first partition plate 14 and the second side wall 13 surround the first sub-cavity 1121, and the second partition plate 15, the first partition plate 14 and the first side wall 12 surround the second sub-cavity 1122, so that the first rotating assembly 2 and the fourth rotating assembly 5 are attached and fixed using the first cavity 111. This allows for the mounting and fixing of the second rotating assembly 3 and the third rotating assembly 4, respectively, using the first sub-cavities 1121 and 1122 of the second cavity 112, and by setting the first rotating assembly 2 as the first drive member 21 and the first rotating part 22, the first rotating part 22 is connected to the output terminal of the first drive member 21 and is installed eccentrically, and by setting the second rotating assembly 3 as the second drive member 31 and the second rotating part 32, the second rotating part 32 is connected to the output terminal of the second drive member 31. The first and second rotating parts are set up so that they drive the first and second rotating parts 22 and the second rotating parts 32 in a synchronous manner, and the first and second rotating parts 21 and the second rotating parts 31 are controlled so that they drive the first and second rotating parts 22 and the second rotating parts 32 in a synchronous manner, by setting up the third rotating assembly 4 as the third drive member 41 and the third rotating part 42, the third rotating part 42 is connected to the output terminal of the third drive member 41 and is set up so that they drive the first and second rotating parts 22 and the second rotating parts 32,When the first rotating part 22 and the second rotating part 32 simultaneously collide with the first partition plate 14, or simultaneously collide with the second side wall 13 and the second partition plate 15, respectively, the exciter 100 has a first state in which it rotates clockwise. By controlling the third drive member 41 and the fourth drive member 51 to drive the third rotating part 42 and the fourth rotating part 52 in synchronous motion, when the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first partition plate 14, or simultaneously collide with the second partition plate 15 and the first side wall 12, respectively, the exciter 100 has a second state in which it rotates counterclockwise. Thus, the exciter 100 can generate two unidirectional rotational sensations on the same coordinate axis at high speed and multi-frequency by utilizing high-frequency drive for a long period of time, that is, the exciter 100 can generate clockwise rotational sensations and counterclockwise rotational sensations. At the same time, in addition to effectively simplifying the structure of the exciter 100, the exciter 100 can achieve high-speed continuous operation and generate a powerful and clear sense of force.

[0049] Selectively, the structure of the first rotational assembly 2 and the structure of the second rotational assembly 3 are the same, and the structure of the third rotational assembly 4 and the structure of the fourth rotational assembly 5 are the same. Selectively, the structure of the first rotational assembly 2, the structure of the second rotational assembly 3, the structure of the third rotational assembly 4, and the structure of the fourth rotational assembly 5 are all the same.

[0050] In one embodiment, as shown in Figures 1 to 6, the first drive member 21, the second drive member 31, the third drive member 41, and the fourth drive member 51 are all rotor motors on which a rotating shaft 211 is installed. Axle holes 221 are installed in the first rotating part 22, the second rotating part 32, the third rotating part 42, and the fourth rotating part 52, and the axle holes 221 are installed eccentrically in the first rotating part 22, the second rotating part 32, the third rotating part 42, and the fourth rotating part 52, with the rotating shaft 211 drilled inside the axle holes 221.

[0051] To make it clear, the structure of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may be regular or irregular in shape. Selectively, the shape of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may be circular, elliptical, quadrilateral, triangular, or polygonal. The shaft hole 221 does not coincide with the center of the shape of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52. Of course, the shape of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may be irregular in shape, and is not limited thereto.

[0052] In this embodiment, the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51 are set as rotor motors, and the rotational structure of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52, which are installed eccentrically, is driven using the rotor motors. 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.

[0053] To make it understandable, the exciter 100 is further ensured to generate a strong and clear sense of force in a unidirectional rotational direction. The first rotating assembly 2 in the first cavity 111 and the second rotating assembly 3 in the first subcavity 1121 are positioned symmetrically with respect to the first partition plate 14 between the second partition plate 15 and the second side wall 13, and the third rotating assembly 4 in the second subcavity 1122 and the fourth rotating assembly 5 in the first cavity 111 are positioned symmetrically with respect to the first partition plate 14 between the second partition plate 15 and the first side wall 12. Selectively, the first rotating part 22 and the second rotating part 32 have the same weight, and the third rotating part 42 and the fourth rotating part 52 have the same weight. The shape contours of the first rotating part 22 and the second rotating part 32 are the same, and the shape contours of the third rotating part 42 and the fourth rotating part 52 are the same.

[0054] To make it easier to understand, the exciter 100 further ensures that it generates a strong and clear sense of force in a unidirectional rotational direction. The drive frequencies of the first drive member 21 and the second drive member 31 are the same, and the drive frequencies of the third drive member 41 and the fourth drive member 51 are the same. The drive voltages of the first drive member 21 and the second drive member 31 are the same, and the drive voltages of the third drive member 41 and the fourth drive member 51 are the same.

[0055] In one embodiment, the first rotating part 22, the second rotating part 32, the third rotating part 42, and the fourth rotating part 52 each include at least one mass block 222. As can be seen, the material of the mass block 222 may be metallic, i.e., the mass block 222 is made of metallic material. Of course, the mass block 222 may also be non-metallic, i.e., the mass block 222 is made of non-metallic material.

[0056] Furthermore, in order to generate a powerful and clear sense of force in the exciter 100, the mass blocks 222 of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 employ a relatively heavy structure, and selectively, the mass blocks 222 are manufactured using metal materials. To further increase the mass of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52, the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may have a counterweight or multiple mass blocks 222 installed on a mass block 222, the counterweight or multiple mass blocks 222 being located radially or circumferentially to the rotation center of the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52, and the shaft hole 221 being located eccentrically to the formed first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 (i.e., the shaft hole 221 does not coincide with the center of the formed first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52).

[0057] In this embodiment, as shown in Figures 1 to 6, the number of mass blocks 222 in the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 may be one, two, three, four, or more, and is not limited thereto. In the case of multiple mass blocks 222, the shaft holes 221 on the mass block 222 connected to the rotating shaft 211 of the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51 are located at an eccentric position of the mass block 222. In this case, other mass blocks 222 are connected to the mass block 222 in the radial or circumferential direction, and the distance from the other mass block 222 to the shaft hole 221 is greater than the distance from the other mass block 222 to the center of the mass block 222.

[0058] Of course, the shaft hole 221 may be located at the center of the mass block 222, in which case another mass block 222 may be connected to one side of the mass block 222, thereby the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 of the whole exhibit an eccentric structure, but is not limited thereto.

[0059] Selectively, the first rotating section 22 / second rotating section 32 / third rotating section 42 / fourth rotating section 52 includes three mass blocks 222, where one mass block 222 is connected to the output end of the first drive member 21 / second drive member 31 / third drive member 41 / fourth drive member 51 and is installed eccentrically, the other two mass blocks 222 are sequentially connected and arranged along the radial direction of the first rotating section 22 / second rotating section 32 / third rotating section 42 / fourth rotating section 52, or the other two mass blocks 222 are sequentially connected and arranged along the circumferential direction of the mass block 222.

[0060] In one embodiment, the first partition plate 14 is installed perpendicularly to the first side wall 12, the first partition plate 14 is installed perpendicularly to the second side wall 13, and the first partition plate 14 extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13.

[0061] To make it easier to understand, as shown in Figures 3 to 6, the enclosure 1 may optionally be square, the first side wall 12 and the second side wall 13 may optionally be installed parallel to each other, and the first partition plate 14 extends by connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13 so as to divide the mounting cavity 11 equally.

[0062] Of course, in other embodiments, the first partition plate 14 does not have to be perpendicular to the first side wall 12, nor does the first partition plate 14 have to be perpendicular to the second side wall 13. For example, when the fourth rotating part 52 / first rotating part 22 is installed in a fan shape, and the fourth drive member 51 / first drive member 21 rotates the fourth rotating part 52 / first rotating part 22 by 90° and collides with the first side wall 12 / second side wall 13 or the first partition plate 14, the first partition plate 14 and the first side wall 12 do not have to be installed perpendicularly, nor do the first partition plate 14 and the second side wall 13 have to be installed perpendicularly, and this is not limited thereto. To make it understandable, the first side wall 12 / second side wall 13 may be set up as a two-tiered structure that is installed at an angle, in which case the first partition plate 14 is connected to the angle formed by the first side wall 12 / second side wall 13, in which case the first partition plate 14 is not installed perpendicular to at least one portion of the first side wall 12 / second side wall 13, but is not limited thereto.

[0063] In this embodiment, the second partition plate 15 is installed perpendicular to the first partition plate 14 and connected to the midpoint of the first partition plate 14. As can be understood, the second partition plate 15 is connected to the midpoint of the first partition plate 14 and is positioned between the first side wall 12 and the second side wall 13, and is installed parallel to the first side wall 12 and the second side wall 13, such that the second partition plate 15 divides the second cavity 112 equally. Selectively, the first subcavity 1121 and the second subcavity 1122 are installed symmetrically with respect to the second partition plate 15.

[0064] Of course, in other embodiments, the second partition plate 15 does not have to be installed perpendicular to the first partition plate 14. For example, when the second rotating part 32 / third rotating part 42 is installed in a fan shape, and the second drive member 31 / third drive member 41 rotates the second rotating part 32 / third rotating part 42 by 90° and collides with the second partition plate 15 or the first partition plate 14, the second partition plate 15 and the first partition plate 14 do not have to be installed perpendicularly, and this is not limited thereto.

[0065] To ensure that the first rotating part 22 and the second rotating part 32 of the first rotating assembly 2 and the second rotating assembly 3, located in the right-hand portion of the housing 1, rotate in the same direction clockwise or counterclockwise, the first rotating assembly 2 in the first cavity 111 and the second rotating assembly 3 in the first sub-cavity 1121 are installed symmetrically around the center. To ensure that the third rotating part 42 and the fourth rotating part 52 of the third rotating assembly 4 and the fourth rotating assembly 5, located in the left-hand portion of the housing 1, rotate in the same direction counterclockwise or clockwise, the third rotating assembly 4 in the second sub-cavity 1122 and the fourth rotating assembly 5 in the first cavity 111 are installed symmetrically around the center.

[0066] Selectively, the first rotational assembly 2 and the second rotational assembly 3 are installed symmetrically around the center, and the third rotational assembly 4 and the fourth rotational assembly 5 are installed symmetrically around the center.

[0067] In this embodiment, as shown in Figures 3 to 6, the first drive member 21 is installed close to the connection point between the second side wall 13 and the first partition plate 14, and the fourth drive member 51 is installed close to the connection point between the first side wall 12 and the first partition plate 14, thereby installing the first drive member 21 and the fourth drive member 51 symmetrically with respect to the second partition plate 15. The second drive member 31 is installed close to the connection point between the second partition plate 15 and the first partition plate 14, and the third drive member 41 is installed close to the connection point between the second partition plate 15 and the first partition plate 14, thereby installing the second drive member 31 and the third drive member 41 symmetrically with respect to the second partition plate 15.

[0068] In one embodiment, when it is defined that the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively, the first rotating part 22 and the second rotating part 32 form a first impact point 131 and a second impact point 151 on the second side wall 13 and the second partition plate 15, respectively, and the distance from the first impact point 131 to the first partition plate 14 is the same as the distance from the second impact point 151 to the first partition plate 14.

[0069] In this embodiment, as shown in Figure 3, in order to ensure that the distance from the first impact point 131 and the second impact point 151, formed when the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15 respectively, to the first partition plate 14 is the same, the output end of the first drive member 21 (i.e., the rotation center of the first rotating part 22) is located on the square segment of the angle between the second side wall 13 and the first partition plate 14, and the output end of the second drive member 31 (i.e., the rotation center of the second rotating part 32) is located on the square segment of the angle between the second partition plate 15 and the first partition plate 14.

[0070] In one embodiment, when it is defined that the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12, respectively, the third rotating part 42 and the fourth rotating part 52 form a third impact point 152 and a fourth impact point 121 on the second partition plate 15 and the first side wall 12, respectively, and the distance from the third impact point 152 to the first partition plate 14 is the same as the distance from the fourth impact point 121 to the first partition plate 14.

[0071] In this embodiment, as shown in Figure 5, in order to ensure that the distance from the third impact point 152 and the fourth impact point 121, formed when the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12 respectively, to the first partition plate 14 is the same, the output end of the third drive member 41 (i.e., the rotation center of the third rotating part 42) is located on the square segment of the angle between the second partition plate 15 and the first partition plate 14, and the output end of the fourth drive member 51 (i.e., the rotation center of the fourth rotating part 52) ​​is located on the square segment of the angle between the first side wall 12 and the first partition plate 14.

[0072] In one embodiment, as shown in Figures 3 to 6, when it is defined that the first rotating part 22 collides with the first side wall 12, the first rotating part 22 forms a first collision point on the second side wall 13; when it is defined that the second rotating part 32 collides with the second partition plate 15, the second rotating part 32 forms a second collision point on the second partition plate 15; when it is defined that the third rotating part 42 collides with the second partition plate 15, the third rotating part 42 forms a third collision point on the second partition plate 15; and when it is defined that the fourth rotating part 52 collides with the first side wall 12, the fourth rotating part 52 forms a fourth collision point on the first side wall 12. Selectively, the distance from the first collision point to the first partition plate 14 and the distance from the fourth collision point to the first partition plate 14 are the same. The distance from the second collision point to the first partition plate 14 is the same as the distance from the third collision point to the first partition plate 14.

[0073] To make it clear, the shape contour of the first rotating part 22 / second rotating part 32 is the same as the shape contour of the third rotating part 42 / fourth rotating part 52, that is, the structure of the first rotating assembly 2 / second rotating assembly 3 is the same as the structure of the third rotating assembly 4 / fourth rotating assembly 5.

[0074] In one embodiment, as shown in Figures 3 and 4, the angle at which the first drive member 21 rotates the first rotating part 22 is selectively 90°, and the angle at which the second drive member 31 rotates the second rotating part 32 is selectively 90°. When it is defined that the first drive member 21 / second drive member 31 rotates the first rotating part 22 / second rotating part 32 in the forward direction, the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively. When it is defined that the first drive member 21 / second drive member 31 rotates the first rotating part 22 / second rotating part 32 in the reverse direction, the first rotating part 22 / second rotating part 32 simultaneously collide with the first partition plate 14.

[0075] In this embodiment, as shown in Figures 1, 3 to 6, the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed parallel to each other. The first partition plate 14 is perpendicular to the first side wall 12 and the second side wall 13, and extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13. The second partition plate 15 is installed perpendicular to the first partition plate 14 and connected to the midpoint of the first partition plate 14. The first drive member 21 is installed close to the connection point between the second side wall 13 and the first partition plate 14, and the second drive member 31 is installed close to the connection point between the second partition plate 15 and the first partition plate 14.

[0076] Selectively, the first drive member 21 is positioned diagonally across the angle formed by the second side wall 13 and the first partition plate 14, and the second drive member 31 is positioned diagonally across the angle formed by the second partition plate 15 and the first partition plate 14.

[0077] To make it easier to understand, the first rotating part 22 is located on the opposite side of the angle between the second side wall 13 of the first drive member 21 and the first partition plate 14, and the second rotating part 32 is located on the opposite side of the angle between the second partition plate 15 of the second drive member 31 and the first partition plate 14, so that when the first drive member 21 rotates the first rotating part 22 by 90°, the first rotating part 22 collides with the second side wall 13 or the first partition plate 14, and when the second drive member 31 rotates the second rotating part 32 by 90°, the second rotating part 32 collides with the second partition plate 15 or the first partition plate 14.

[0078] Of course, the angle at which the first drive member 21 rotates the first rotating part 22 may be greater than 90° or less than 90°. The angle at which the second drive member 31 rotates the second rotating part 32 may be greater than 90° or less than 90°. Furthermore, if the connecting line between the rotation axis 211 of the first drive member 21 and the center of the first rotating part 22 is not parallel to the first partition plate 14 or the second side wall 13, the angle at which the first drive member 21 rotates the first rotating part 22 may be greater than 90° or less than 90°. If the connecting line between the rotation axis 211 of the second drive member 31 and the center of the second rotating part 32 is not parallel to the first partition plate 14 or the second partition plate 15, the angle at which the second drive member 31 rotates the second rotating part 32 may be greater than 90° or less than 90°, and is not limited thereto.

[0079] To make it clear, when the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively, the connecting line between the rotation axis 211 of the first drive member 21 / second drive member 31 and the center of the first rotating part 22 / second rotating part 32 is not parallel to the second side wall 13 and the second partition plate 15, and when the first rotating part 22 / second rotating part 32 simultaneously collide with the first partition plate 14, the first drive member 21 / second The connecting line between the rotation axis 211 of the drive member 31 and the center of the first rotating part 22 / second rotating part 32 is not parallel to the first partition plate 14. In this case, the angle at which the first drive member 21 rotates the first rotating part 22 may be greater than 90° or less than 90°, and the angle at which the second drive member 31 rotates the second rotating part 32 may be greater than 90° or less than 90°, and is not limited thereto.

[0080] In this embodiment, as shown in Figure 3, when the first drive member 21 and the second drive member 31 simultaneously drive the first rotating part 22 and the second rotating part 32 to rotate clockwise, the first drive member 21 and the second drive member 31 drive the first rotating part 22 and the second rotating part 32 to rotate in the forward direction, that is, the first drive member 21 and the second drive member 31 rotate in the forward direction, so that the first rotating part 22 and the second rotating part 32 simultaneously collide with the second side wall 13 and the second partition plate 15, respectively. As shown in Figure 4, when the first drive member 21 and the second drive member 31 simultaneously drive the first rotating part 22 and the second rotating part 32 to rotate counterclockwise, the first drive member 21 and the second drive member 31 drive the first rotating part 22 and the second rotating part 32 to rotate in the opposite direction, that is, the first drive member 21 and the second drive member 31 rotate in the opposite direction, so that the first rotating part 22 and the second rotating part 32 collide with the first partition plate 14 at the same time.

[0081] In one embodiment, the angle at which the third drive member 41 rotates the third rotating part 42 is selectively 90°, and the angle at which the fourth drive member 51 rotates the fourth rotating part 52 is selectively 90°. When it is defined that the third drive member 41 / fourth drive member 51 rotates the third rotating part 42 / fourth rotating part 52 in the forward direction, the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12, respectively. When it is defined that the third drive member 41 / fourth drive member 51 rotates the third rotating part 42 / fourth rotating part 52 in the reverse direction, the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first partition plate 14.

[0082] In this embodiment, as shown in Figures 1, 3 to 6, the third drive member 41 is installed close to the connection point between the second partition plate 15 and the first partition plate 14, and the fourth drive member 51 is installed close to the connection point between the first side wall 12 and the first partition plate 14. Selectively, the third drive member 41 is located diagonally across the angle formed by the second partition plate 15 and the first partition plate 14, and the fourth drive member 51 is located diagonally across the angle formed by the first side wall 12 and the first partition plate 14.

[0083] To make it easier to understand, the third rotating part 42 is located on the opposite side of the angle between the second partition plate 15 and the first partition plate 14 of the third drive member 41, and the fourth rotating part 52 is located on the opposite side of the angle between the first side wall 12 and the first partition plate 14 of the fourth drive member 51, so that when the third drive member 41 rotates the third rotating part 42 by 90°, the third rotating part 42 collides with the second partition plate 15 or the first partition plate 14, and when the fourth drive member 51 rotates the fourth rotating part 52 by 90°, the fourth rotating part 52 collides with the second partition plate 15 or the first partition plate 14.

[0084] Of course, the angle at which the third drive member 41 rotates the third rotating part 42 may be greater than 90° or less than 90°. The angle at which the fourth drive member 51 rotates the fourth rotating part 52 may be greater than 90° or less than 90°. Furthermore, if the connecting line between the rotation axis 211 of the third drive member 41 and the center of the third rotating part 42 is not parallel to the first partition plate 14 or the second partition plate 15, the angle at which the third drive member 41 rotates the third rotating part 42 may be greater than 90° or less than 90°. If the connecting line between the rotation axis 211 of the fourth drive member 51 and the center of the fourth rotating part 52 is not parallel to the first partition plate 14 or the first side wall 12, the angle at which the fourth drive member 51 rotates the fourth rotating part 52 may be greater than 90° or less than 90°, and is not limited thereto.

[0085] To make it understandable, when the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12, respectively, the connecting line between the rotation axis 211 of the third drive member 41 / fourth drive member 51 and the center of the third rotating part 42 / fourth rotating part 52 is not parallel to the second partition plate 15 and the first side wall 12, and when the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the first partition plate 14, the third drive member 41 / The connecting line between the rotation axis 211 of the fourth drive member 51 and the center of the third rotating part 42 / fourth rotating part 52 is not parallel to the first partition plate 14. In this case, the angle at which the third drive member 41 rotates the third rotating part 42 may be greater than 90° or less than 90°, and the angle at which the fourth drive member 51 rotates the fourth rotating part 52 may be greater than 90° or less than 90°, and is not limited thereto.

[0086] In this embodiment, as shown in Figure 5, when the third drive member 41 / fourth drive member 51 simultaneously rotate the third rotating part 42 / fourth rotating part 52 counterclockwise, the third drive member 41 / fourth drive member 51 rotates the third rotating part 42 / fourth rotating part 52 in the forward direction, that is, the third drive member 41 / fourth drive member 51 rotates in the forward direction, so that the third rotating part 42 and the fourth rotating part 52 simultaneously collide with the second partition plate 15 and the first side wall 12, respectively. As shown in Figure 6, when the third drive member 41 and the fourth drive member 51 simultaneously drive the third rotating part 42 and the fourth rotating part 52 clockwise, the third drive member 41 and the fourth drive member 51 drive the third rotating part 42 and the fourth rotating part 52 in the opposite direction, that is, the third drive member 41 and the fourth drive member 51 rotate in the opposite direction, so that the third rotating part 42 and the fourth rotating part 52 collide with the first partition plate 14 at the same time.

[0087] In one embodiment, when it is defined that the first rotating part 22 collides with the second side wall 13 or the first partition plate 14, a first collision point is formed on the second side wall 13 or the first partition plate 14, and the first rotating assembly 2 further includes a first buffer part 23, the first buffer part 23 being installed on the second side wall 13 and / or the first partition plate 14 and located at the first collision point, or the first buffer part 23 being installed on the first rotating part 22, and the first buffer part 23 coming into contact with the first collision point when the first drive member 21 rotates the first rotating part 22.

[0088] In this embodiment, as shown in Figures 1 to 6, by installing the first buffer section 23, the impact force of the first rotating section 22 can be adjusted and buffered using the first buffer section 23, and the sensitivity frequency of the vibration wave can be adjusted using the first buffer section 23, thereby making the peak tip in Figure 7 sharper, and the first buffer section 23 also has a noise reduction effect.

[0089] To make it easier to understand, when the first rotating part 22 collides with the second side wall 13 / first partition plate 14, the first rotating part 22 forms a first impact point 131 on the second side wall 13 / first partition plate 14, and the first impact point 131 coincides with the first collision point.

[0090] In this embodiment, the first buffer portion 23 may be installed on the second side wall 13 and / or the first partition plate 14 of the housing 1, and may also be located at the first collision point. Of course, the first buffer portion 23 may also be installed on the first rotating portion 22, so that when the first drive member 21 rotates the first rotating portion 22, the first buffer portion 23 comes into contact with the first collision point.

[0091] In this embodiment, the first buffer section 23 includes a plurality of first buffer sections 23, which are installed on the second side wall 13 and the first partition plate 14, respectively. Alternatively, the plurality of first buffer sections 23 are installed on opposing sides of the first rotating section 22, so that when the first rotating section 22 collides with the second side wall 13 / first partition plate 14, the second side wall 13 / first partition plate 14 comes into contact with the first buffer section 23, but this is not limited to this embodiment.

[0092] Selectively, the material of the first buffer section 23 is made from a compressible material such as foam, sponge, or rubber mat, but is not limited thereto. In other words, the first buffer section 23 is not made from a rigid material.

[0093] In this embodiment, the first drive member 21 is fixedly mounted within the first cavity 111 of the mounting cavity 11, and without any change in their relative positions, the multiple mass blocks 222 of the first rotating part 22 are combined as a single unit, and the entirety of the multiple mass blocks 222 is an eccentric mass block that moves synchronously.

[0094] In one embodiment, when it is defined that the second rotating part 32 collides with the second partition plate 15 or the first partition plate 14, a second collision point is formed on the second partition plate 15 or the first partition plate 14, and the second rotating assembly 3 further includes a second buffer part 33, the second buffer part 33 being installed on the second partition plate 15 and / or the first partition plate 14 and located at the second collision point, or the second buffer part 33 being installed on the second rotating part 32, and the second buffer part 33 contacting the second collision point when the second drive member 31 rotates the second rotating part 32.

[0095] In this embodiment, as shown in Figures 1 to 6, by installing the second buffer section 33, the impact force of the second rotating section 32 can be adjusted and buffered using the second buffer section 33, and the sensitivity frequency of the vibration wave can be adjusted using the second buffer section 33, thereby making the peak tip in Figure 7 sharper, and the second rotating section 32 also has a noise reduction effect.

[0096] To make it easier to understand, when the second rotating part 32 collides with the second partition plate 15 / first partition plate 14, the second rotating part 32 forms a second impact point 151 on the second partition plate 15 / first partition plate 14, and the second impact point 151 coincides with the second collision point.

[0097] In this embodiment, the second buffer portion 33 may be installed on the second partition plate 15 and / or the first partition plate 14 of the housing 1, and may also be located at the second collision point. Of course, the second buffer portion 33 may also be installed on the second rotating portion 32, so that when the second drive member 31 rotates the second rotating portion 32, the second buffer portion 33 comes into contact with the second collision point.

[0098] In this embodiment, the second buffer portion 33 includes a plurality of second buffer portions 33, which are installed on the second partition plate 15 and the first partition plate 14, respectively. Alternatively, the plurality of second buffer portions 33 are installed on opposing sides of the second rotating portion 32, so that when the second rotating portion 32 collides with the second partition plate 15 / first partition plate 14, the second partition plate 15 / first partition plate 14 come into contact with the second buffer portion 33, but this is not limited thereto.

[0099] Selectively, the material of the second buffer section 33 is made from a compressible material such as foam, sponge, or rubber mat, but is not limited thereto. In other words, the second buffer section 33 is not made from a rigid material.

[0100] In this embodiment, the second drive member 31 is fixedly mounted within the first sub-cavity 1121 of the mounting cavity 11, and the multiple mass blocks 222 of the second rotating part 32 are combined integrally without any change in their relative positions, and the entire set of multiple mass blocks 222 is an eccentric mass block that moves synchronously.

[0101] In one embodiment, when it is defined that the third rotating part 42 collides with the second partition plate 15 or the first partition plate 14, a third collision point is formed on the second partition plate 15 or the first partition plate 14, and the third rotating assembly 4 further includes a third buffer part 43, the third buffer part 43 is installed on the second partition plate 15 and / or the first partition plate 14 and is located at the third collision point, or the third buffer part 43 is installed on the third rotating part 42 and the third buffer part 43 contacts the third collision point when the third drive member 41 rotates the third rotating part 42.

[0102] In this embodiment, as shown in Figures 1 to 6, by installing a third buffer section 43, the impact force of the third rotating section 42 can be adjusted and buffered using the third buffer section 43, and the sensitivity frequency of the vibration wave can be adjusted using the third buffer section 43, thereby making the peak tip in Figure 8 sharper, and the third rotating section 42 also has a noise reduction effect.

[0103] To make it easier to understand, when the third rotating part 42 collides with the second partition plate 15 / first partition plate 14, the third rotating part 42 forms a third impact point 152 on the second partition plate 15 / first partition plate 14, and the third impact point 152 coincides with the third collision point.

[0104] In this embodiment, the third buffer portion 43 may be installed on the second partition plate 15 and / or the first partition plate 14 of the housing 1, and may also be located at the third collision point. Of course, the third buffer portion 43 may also be installed on the third rotating portion 42, so that when the third drive member 41 rotates the third rotating portion 42, the third buffer portion 43 comes into contact with the third collision point.

[0105] In this embodiment, the third buffer portion 43 includes a plurality of third buffer portions 43, which are installed on the second partition plate 15 and the first partition plate 14, respectively. Alternatively, the plurality of third buffer portions 43 are installed on opposing sides of the third rotating portion 42, so that when the third rotating portion 42 collides with the second partition plate 15 / first partition plate 14, the second partition plate 15 / first partition plate 14 come into contact with the third buffer portion 43, but this is not limited to this.

[0106] Selectively, the material of the third buffer section 43 is made from a compressible material such as foam, sponge, or rubber mat, but is not limited thereto. In other words, the third buffer section 43 is not made from a rigid material.

[0107] In this embodiment, the third drive member 41 is fixedly mounted within the second sub-cavity 1122 of the mounting cavity 11, and the multiple mass blocks 222 of the third rotating part 42 are combined integrally without any change in their relative positions, and the entire set of multiple mass blocks 222 is an eccentric mass block that moves synchronously.

[0108] In one embodiment, when it is defined that the fourth rotating part 52 collides with the first side wall 12 or the first partition plate 14, a fourth collision point is formed on the first side wall 12 or the first partition plate 14, and the fourth rotating assembly 5 further includes a fourth buffer part 53, the fourth buffer part 53 being installed on the first side wall 12 and / or the first partition plate 14 and located at the fourth collision point, or the fourth buffer part 53 being installed on the fourth rotating part 52, and the fourth buffer part 53 contacting the fourth collision point when the fourth drive member 51 rotates the fourth rotating part 52.

[0109] In this embodiment, as shown in Figures 1 to 6, by installing the fourth buffer section 53, the impact force of the fourth rotating section 52 can be adjusted and buffered using the fourth buffer section 53, and the sensitivity frequency of the vibration wave can be adjusted using the fourth buffer section 53, thereby making the peak tip in Figure 8 sharper, and the fourth buffer section 53 also has a noise reduction effect.

[0110] To make it easier to understand, when the fourth rotating part 52 collides with the first side wall 12 / first partition plate 14, the fourth rotating part 52 forms a fourth impact point 121 on the first side wall 12 / first partition plate 14, and the fourth impact point 121 coincides with the fourth collision point.

[0111] In this embodiment, the fourth buffer portion 53 may be installed on the first side wall 12 and / or the first partition plate 14 of the housing 1, and may also be located at the fourth collision point. Of course, the fourth buffer portion 53 may also be installed on the fourth rotating portion 52, so that when the fourth drive member 51 rotates the fourth rotating portion 52, the fourth buffer portion 53 comes into contact with the fourth collision point.

[0112] In this embodiment, the fourth buffer section 53 includes a plurality of them, with the plurality of fourth buffer sections 53 being installed on the first side wall 12 and the first partition plate 14, respectively. Alternatively, the plurality of fourth buffer sections 53 are installed on opposing sides of the fourth rotating section 52, so that when the fourth rotating section 52 collides with the first side wall 12 / first partition plate 14, the first side wall 12 / first partition plate 14 comes into contact with the fourth buffer section 53, but this is not limited to this embodiment.

[0113] The material of the fourth buffer section 53 is selectively made from a compressible material such as foam, sponge, or rubber mat, but is not limited thereto. In other words, the fourth buffer section 53 is not made from a rigid material.

[0114] In this embodiment, the fourth drive member 51 is fixedly mounted within the first cavity 111 of the mounting cavity 11, and the multiple mass blocks 222 of the fourth rotating part 52 are combined integrally without any change in their relative positions, and the entire set of multiple mass blocks 222 is an eccentric mass block that moves synchronously.

[0115] To make it easier to understand, when the rotor motor is driven, the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 rotate rapidly around the rotor motor's rotation axis 211. When the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 move to two extreme motion positions, they collide with the corresponding second side wall 13 / second partition plate 15 and second partition plate 15 / first side wall 12 of the housing 1, respectively. When the first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 collide with the housing 1, a rapid braking effect occurs, and the housing 1 experiences a corresponding impact sensation. By driving multiple rotor motors in combination, the effects of two extreme states can be realized; that is, one side has a rotational tactile sensation in one direction, and the other side also has a rotational tactile sensation in the same direction. The magnitude of the rotational tactile sensation on both sides is related to the magnitude of the product of the corresponding force and force arm. Furthermore, by utilizing high-frequency drive over extended periods, rapid, multi-frequency rotational tactile sensations in two unidirectional directions on the same coordinate axis can be generated, namely clockwise and counterclockwise rotational tactile sensations.

[0116] Furthermore, when the first rotating part 22 / second rotating part 32 moves to its limit position, the impact forces of the first rotating part 22 / second rotating part 32 on the housing 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple clockwise rotational tactile sensation. When the third rotating part 42 / fourth rotating part 52 moves to its limit position, the impact forces of the third rotating part 42 / fourth rotating part 52 on the housing 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple counterclockwise rotational tactile sensation.

[0117] To make it easier to understand, in the motion cancellation state, when the first rotating part 22 and the second rotating part 32 rotate counterclockwise and collide with the first partition plate 14, the two impact forces generated by the first rotating part 22 and the second rotating part 32 on the housing 1 coincide with the line connecting the centers of mass of the first rotating part 22 and the second rotating part 32, thereby causing the housing 1 to receive two forces of the same magnitude and in opposite directions, thus achieving the effect of motion impact cancellation. In another state, that is, when the first rotating part 22 and the second rotating part 32 rotate clockwise and collide with the second side wall 13 and the second partition plate 15, the impact forces of the first rotating part 22 and the second rotating part 32 on the housing 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple clockwise rotational tactile sensation.

[0118] Of course, when the third rotating part 42 and the fourth rotating part 52 rotate clockwise and collide with the first partition plate 14, the two impact forces generated by the third rotating part 42 and the fourth rotating part 52 on the housing 1 coincide with the line connecting the centers of mass of the third rotating part 42 and the fourth rotating part 52, thereby causing the housing 1 to receive two forces of the same magnitude and in opposite directions, thus achieving the effect of canceling out moving impacts. In another state, namely when the third rotating part 42 and the fourth rotating part 52 rotate counterclockwise and collide with the first side wall 12 and the second partition plate 15, the impact forces of the third rotating part 42 and the fourth rotating part 52 on the housing 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple counterclockwise rotational tactile sensation.

[0119] In actual use, it is possible to comprehensively utilize two extremes of the same rotation, and based on the structural division, a set of force arms can be made longer, thereby obtaining better haptic feedback, and this is not limited to this.
