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.

[0004] However, such a device only realizes vibration in a linear direction and is unable to generate a sense of force in a rotational direction. Summary of the Invention [Problem to be solved by the invention]

[0005] The main objective of the present disclosure is to provide an exciter and electronic device, and is intended to provide an exciter that can generate a rotational force sensation, which not only has a simplified structure but can also achieve high-speed continuous operation and generate a powerful and vivid force sensation. [Means for solving the problem]

[0006] In order to achieve the above object, the present disclosure proposes an exciter, the exciter comprising: a housing having a first sidewall and a second sidewall disposed at an angle and having a mounting cavity disposed therein; a drive member located within the mounting cavity; a rotating part connected to the output end of the driving member and eccentrically installed; Here, the driving member drives the rotating part to rotate, thereby colliding with the first side wall or the second side wall and forming an impact point on the first side wall or the second side wall, and the impact point does not overlap with the center of gravity of the exciter.

[0007] In one embodiment, the angle by which the driving member rotates the rotating part is 90°, When the driving member drives the rotating part to rotate in the forward direction, the rotating part collides with the first side wall, When the drive member drives the rotating part to rotate in the reverse direction, the rotating part collides with the second side wall.

[0008] In one embodiment, the first sidewall is disposed perpendicular to the second sidewall.

[0009] In one embodiment, the drive member is located adjacent to a connection point between the first side wall and the second side wall, And / or, the distance from the impact point of the first side wall to the connection point of the first side wall and the second side wall is the same as the distance from the impact point of the second side wall to the connection point of the first side wall and the second side wall.

[0010] In one embodiment, the exciter further includes a buffer section, The buffer portion is installed on the first side wall and / or the second side wall and is located at the impact point, or the buffer portion is installed on the rotating part and when the driving member rotates the rotating part, the buffer portion abuts against the impact point.

[0011] In one embodiment, the driving member is a rotor motor having a rotating shaft, a shaft hole is formed in the rotating part, the shaft hole is eccentrically disposed in the rotating part, and the rotating shaft is drilled in the shaft hole; In one embodiment, the rotating part includes at least one mass block; The mass block may be made of a metallic material, or the mass block may be made of a non-metallic material.

[0012] In one embodiment, the rotating part includes three mass blocks, one mass block is connected to an output end of the driving member and is eccentrically disposed; The other two mass blocks are connected and arranged in sequence along the radial direction of the rotating part, or the other two mass blocks are connected and arranged in sequence along the circumferential direction of the mass blocks.

[0013] The present disclosure further proposes an electronic device including an equipment body having an installation space and the above-mentioned exciter installed in the installation space.

[0014] In one embodiment, the impact point of the exciter does not overlap with the center of gravity of the electronic device. [Effects of the Invention]

[0015] The exciter of the technical solution disclosed herein forms a mounting cavity within the housing, and uses the mounting cavity to mount, fix, and protect the driving member and the rotating unit. The housing also forms a first side wall and a second side wall that are angled relative to each other, so that the rotating unit is connected to the output end of the driving member and is eccentrically installed. When the driving member rotates the rotating unit, the rotating unit collides with the first side wall or the second side wall, forming an impact point on the first side wall or the second side wall. The impact point does not coincide with the center of gravity of the exciter. When the rotating unit collides with the first side wall or the second side wall, torque is generated in the rotational direction, and the exciter can generate a force in the rotational direction. At the same time, the driving member is installed to drive the rotation structure of the eccentrically installed rotating unit. This not only effectively simplifies the structure of the exciter, but also enables the exciter to achieve high-speed continuous operation and generate a strong and clear force.

[0023] Conventional vibration devices create the illusion of a force acting in a certain direction by constantly generating asymmetric vibrations, which are called anisotropic vibrations.

[0024] 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.

[0025] However, such a device only realizes vibration in a linear direction and is unable to generate a sense of force in a rotational direction.

[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 6, in an embodiment of the present disclosure, the exciter 100 includes a housing 1, a driving member 2, and a rotating unit 3, a mounting cavity 11 is installed in the housing 1, the housing 1 has a first side wall 12 and a second side wall 13 installed at an angle, the driving member 2 is installed in the mounting cavity 11, the rotating unit 3 is connected to the output end of the driving member 2 and is installed eccentrically, wherein the driving member 2 rotates the rotating unit 3, thereby impacting the first side wall 12 or the second side wall 13 and forming an impact point 14 on the first side wall 12 or the second side wall 13, and the impact point 14 does not overlap with the center of gravity of the exciter 100.

[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, in order to generate a rotational force sensation in the exciter 100, the housing 1 has a first side wall 12 and a second side wall 13 that are installed at an angle, and the first side wall 12 and the second side wall 13 may be the outer walls of the housing 1, or may be side walls or partition plate structures installed within the mounting cavity 11 of the housing 1, and are not limited here.

[0031] Optionally, the housing 1 is installed in a rectangular shape. Furthermore, the housing 1 may alternatively have a square structure. In this embodiment, the driving member 2 is installed in the mounting cavity 11, and the driving member 2 may be directly fixed to the inner wall of the housing 1 or may be attached to the first mounting cavity 11 by other structures such as a bracket or a mounting seat.

[0032] In this embodiment, the rotating part 3 is connected to the output end of the driving member 2 and is installed eccentrically. 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 seen, by controlling the driving member 2 to rotate the rotating part 3, when the rotating part 3 collides with the first side wall 12 or the second side wall 13, the rotating part 3 forms an impact point 14 on the first side wall 12 or the second side wall 13, and the impact point 14 does not coincide with the center of gravity of the exciter 100, so that when the rotating part 3 collides with the first side wall 12 or the second side wall 13, a torque can be generated in the rotational direction, thereby allowing the exciter 100 to generate a force in the rotational direction. At the same time, by installing the driving member 2, the rotation structure of the rotating part 3 which is installed eccentrically can be driven, which not only effectively simplifies the structure of the exciter 100, but also allows the exciter 100 to achieve high-speed continuous operation and generate a strong and clear force.

[0034] It should be noted that the exciter 100 further includes a controller or control structure, which can control the drive member 2 to rotate the rotating part 3. As can be understood, the controller or control structure may be a separate controller or remote control, or may be a control circuit or a control button or other structure integrated in the exciter 100, and is not limited thereto.

[0035] In this embodiment, as shown in Fig. 3, the driving member 2 is controlled to rotate in the forward direction and the rotating unit 3 is driven to rotate counterclockwise so that the rotating unit 3 collides with the first side wall 12, thereby generating torque in the counterclockwise direction, and the exciter 100 is thereby able to generate a sense of force in the counterclockwise rotation direction. As shown in Fig. 4, the driving member 2 is controlled to rotate in the reverse direction and the rotating unit 3 is driven to rotate clockwise so that the rotating unit 3 collides with the second side wall 13, thereby generating torque in the clockwise direction, and the exciter 100 is thereby able to generate a sense of force in the clockwise rotation direction.

[0036] As can be seen from Fig. 7, the exciter 100 is installed in an electronic device 600 or a product, and an acceleration sensor is employed to detect the continuous unidirectional moment generated by the electronic device 600 when the exciter 100 vibrates. In Fig. 7, chA is a control signal for rotating the driving member 2 forward, chB is a control signal for rotating the driving member 2 reversely, and chC is an acceleration waveform of the acceleration on the electronic device 600, and as can be seen from this, there is a clear unidirectional rotational vibration sensation in the housing 1.

[0037] The exciter 100 of the present disclosure forms a mounting cavity 11 in the housing 1, and uses the mounting cavity 11 to mount, fix, and protect the driving member 2 and the rotating unit 3. The mounting cavity 11 is also used to form a first side wall 12 and a second side wall 13 that are installed at an angle to the housing 1, so that the rotating unit 3 is connected to the output end of the driving member 2 and is installed eccentrically. Therefore, when the driving member 2 rotates the rotating unit 3, the rotating unit 3 collides with the first side wall 12 or the second side wall 13, and the rotating unit 3 is then pushed against the first side wall 12 or the second side wall 13. 13 forms an impact point 14, and the impact point 14 does not coincide with the center of gravity of the exciter 100, so that when the rotating part 3 collides with the first side wall 12 or the second side wall 13, a torque is generated in the rotational direction, and the exciter 100 can generate a force in the rotational direction. At the same time, the driving member 2 is installed to drive the rotation structure of the rotating part 3 which is installed eccentrically, which not only effectively simplifies the structure of the exciter 100, but also allows the exciter 100 to achieve high-speed continuous operation and generate a strong and clear force.

[0038] In this embodiment, as shown in Figures 1 to 4, the driving member 2 may be a rotor motor in which a rotating shaft 21 is selectively installed, and an axial hole 31 is installed in the rotating part 3, the axial hole 31 is installed eccentrically on the rotating part 3, and the rotating shaft 21 is drilled within the axial hole 31.

[0039] 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.

[0040] In one embodiment, the 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.

[0041] 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).

[0042] In one embodiment, the rotating part 3 includes three mass blocks 32, one mass block 32 is connected to the output end of the driving member 2 and is installed eccentrically, and the other two mass blocks 32 are connected and arranged sequentially along the radial direction of the rotating part 3, or the other two mass blocks 32 are connected and arranged sequentially along the circumferential direction of the mass blocks 32.

[0043] 1 to 4, the number of mass blocks 32 in the 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.

[0044] 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.

[0045] In one embodiment, the angle at which the driving member 2 drives the rotating unit 3 to rotate may optionally be 90°, and when the driving member 2 drives the rotating unit 3 to rotate forward, the rotating unit 3 collides with the first side wall 12, and when the driving member 2 drives the rotating unit 3 to rotate backward, the rotating unit 3 collides with the second side wall 13.

[0046] In this embodiment, as shown in Figures 1, 3 and 4, the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed vertically. The driving member 2 is installed close to the connection point between the first side wall 12 and the second side wall 13. Optionally, the driving member 2 is located on the diagonal line of the angle formed by the first side wall 12 and the second side wall 13.

[0047] Of course, in other embodiments, the second side wall 13 does not have to be installed perpendicular to the first side wall 12. For example, when the rotating unit 3 is installed in a fan shape, if the driving member 2 rotates the rotating unit 3 by 90° and collides with 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 installed perpendicularly, and this is not limited here.

[0048] 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.

[0049] Of course, the angle through which the driving member 2 rotates the rotating unit 3 may be greater than or less than 90°. Incidentally, 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 through which the driving member 2 rotates the rotating unit 3 may be greater than or less than 90°. That is, when the rotating unit 3 collides with the first side wall 12, 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, and when the rotating unit 3 collides with the second side wall 13, 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 second side wall 13. In this case, the angle through which the driving member 2 rotates the rotating unit 3 may be greater than or less than 90°, and is not limited thereto.

[0050] In this embodiment, as shown in Fig. 3, when the driving member 2 drives the rotating part 3 to rotate in the forward direction, i.e., the driving member 2 is defined as rotating in the forward direction, and thereby the driving member 2 drives the rotating part 3 to rotate in the counterclockwise direction, the rotating part 3 collides with the first side wall 12. As shown in Fig. 4, when the driving member 2 drives the rotating part 3 to rotate in the reverse direction, i.e., the driving member 2 is defined as rotating in the reverse direction, and thereby the driving member 2 drives the rotating part 3 to rotate in the clockwise direction, the rotating part 3 collides with the second side wall 13.

[0051] In one embodiment, the distance from the impact point 14 of the first side wall 12 to the connection point between the first side wall 12 and the second side wall 13 is the same as the distance from the impact point 14 of the second side wall 13 to the connection point between the first side wall 12 and the second side wall 13.

[0052] In this embodiment, as shown in Figures 3 and 4, in order to ensure that the distance from the impact point 14 formed when the rotating unit 3 collides with the first side wall 12 to the connection point between the first side wall 12 and the second side wall 13 is the same as the distance from the impact point 14 formed when the rotating unit 3 collides with the second side wall 13 to the connection point between the first side wall 12 and the second side wall 13, the exciter 100 matches the force sense generated in the counterclockwise rotation direction with the force sense generated in the clockwise rotation direction, thereby improving the user's experience.

[0053] In one embodiment, the exciter 100 further includes a buffer portion 4, which is installed on the first side wall 12 and / or the second side wall 13 and is located at the impact point 14, or the buffer portion 4 is installed on the rotating portion 3, and when the driving member 2 rotates the rotating portion 3, the buffer portion 4 abuts against the impact point 14.

[0054] 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 7 sharper, and the buffer unit 4 also has a noise reduction effect.

[0055] As can be seen, the buffer portion 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 impact point 14. Of course, the buffer portion 4 may also be installed on the rotating portion 3, so that the buffer portion 4 abuts against the impact point 14 when the driving member 2 drives the rotating portion 3 to rotate.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] As can be seen, the rotating unit 3 is driven to rotate by controlling the driving member 2. 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 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 feel a corresponding impact. When the impact position is away from the center of gravity of the exciter 100 or the electronic device 600, a corresponding rotational tactile sensation can be generated. When the rotation direction of the output driving member 2 is forward or reverse, the driving force during reversal is reduced using a method such as a chopper or PWM (pulse width modulation), and the impact force during reverse braking is reduced. This allows a unidirectional rotational tactile sensation to be achieved with a simple structure.

[0060] 5 and 6, the present disclosure further proposes an electronic device 600, which includes an equipment body 500 having an installation space 510, and the above-mentioned exciter 100 installed in the installation space 510. The specific structure of the exciter 100 refers to the above embodiments, and since the electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, so it will not be further described here.

[0061] In this embodiment, as shown in FIGS. 5 and 6, the impact point 14 of the exciter 100 does not overlap with the center of gravity 520 of the electronic device.

[0062] As can be seen, the rotating unit 3 is driven to rotate by controlling the driving member 2 of the exciter 100. 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 of the housing 1 of the exciter 100), it collides with the corresponding first side wall 12 or the second side wall 13 of the housing 1. When the rotating unit 3 collides with the first side wall 12 or the second side wall 13 of the housing 1 of the exciter 100, a rapid braking effect occurs, causing the housing 1 to feel a corresponding impact. If the impact position is away from the center of gravity of the electronic device 600, a corresponding rotational tactile sensation can be generated. When the rotation direction of the output driving member 2 is forward or reverse, the driving force during reverse rotation is reduced using a method such as a chopper or PWM (pulse width modulation), and the impact force during reverse braking is reduced. This allows a unidirectional rotational tactile sensation to be achieved with a simple structure.

[0063] The above description is merely a selective embodiment of the present disclosure and does not limit the patent scope of the present disclosure. Any equivalent structural transformation made using the contents of the specification and accompanying drawings of the present disclosure under the concept of the present disclosure, or directly or indirectly applied to other related technical fields, is included in the patent protection scope of the present disclosure.
