Description

Technical Field

[0001] The present invention relates to the technical field of vibration devices, and particularly to drive exciters and electronic devices.

Background Art

[0002] Currently, as a means of reproducing a sense of force, there is a method of inputting an asymmetric signal into a linear resonator and using the human sense to create an illusion of a force acting "as if in a certain direction". In principle, the above method can only generate a continuous directional sense of force, cannot achieve discrete output, and the range of force sense change is not large. Since the asymmetric signal generates extra vibrations and cannot generate a purely directional output, the sense of direction of the vibrations obtained by the above method is blurred and the efficiency is low.

[0003] In addition, a linear resonator or exciter adopting the above method still performs braking and resetting using a damping material such as a spring, that is, realizes the above functions in the form of solid contact. When using the solid contact type, a steep reaction force is generated during contact. Therefore, if the elasticity of the material is strong, repulsion occurs, and at this time, the mass point vibrates isotropically. If the damping characteristics of the material are too large, the kinetic energy of the braked mass point changes into thermal energy, the energy loss increases, and the efficiency decreases. Furthermore, wear and deformation of the contact surface are inevitable, and the long-term stability of the structure cannot be guaranteed.

[0004] The above content is only used to assist in understanding the technical solution of the present invention, and does not represent an admission that the above content is prior art.

[0018] The technical solution of this application significantly expands the asymmetry of anisotropic vibration and allows for the discrete presentation of asymmetric vibrations in a short time. By generating vibrations that are close to the asymmetric vibration force that actually occurs, a clear sense of force in a certain direction can be presented discretely in a short time.

[0021] The realization of the purpose, functional features and advantages of the present invention will be further described by combining the embodiments and referring to the accompanying drawings.

Modes for Carrying Out the Invention

[0022] The following clearly and completely describes the technical solutions in embodiments of the present invention, linking them to the accompanying drawings. Clearly, the embodiments described are only a subset of the present invention, not all embodiments. All other embodiments obtained based on the embodiments of the present invention without the creative effort of those skilled in the art are all within the scope of the protection of the present invention.

[0023] In the embodiments of the present invention, all directional indicators (for example, up, down, left, right, front, back, etc.) are used solely to describe the relative positional relationships and movements between each component in a specific orientation (as shown in the drawings). If this specific orientation changes, the directional indicators will also change accordingly.

[0024] Furthermore, in this invention, descriptions relating to "first," "second," etc., are used solely for descriptive purposes and should not be understood as indicating or suggesting their relative importance or implicitly indicating the number of specified technical features. Thus, features limited to "first" or "second" may explicitly or implicitly include at least one such feature. Also, while the technical solutions between each embodiment can be combined, this must be based on what a person skilled in the art can achieve. If a combination of technical solutions results in a contradiction or is not feasible, such a combination of technical solutions should be considered nonexistent and is not included in the scope of protection required by this invention.

[0025] Anisotropic vibration, also known as asymmetric vibration, is achieved by inputting an asymmetric signal to a vibration device such as a vibration motor, thereby generating a pulling sensation in a certain direction for the user holding the device. Vibration devices that can achieve anisotropic vibration are often used in devices such as game controllers, and the asymmetric type of vibration provides good feedback to the user.

[0026] In the vibration device relating to the technical solution of the present application, the so-called "discrete" is a concept opposite to "sustained." For example, after one excitation, the vibration motor sustains the vibration, outputting a sustained vibration to the vibration device, causing the user to feel a vibration or tension that lasts for a certain period of time, resulting in sustained vibration. On the other hand, if the vibration device outputs vibrations in a clear direction once or multiple times at intervals within a certain period of time, it results in discrete anisotropic vibration.

[0027] As shown in Figure 8, both figures in Figure 8 show that the waveform repeats at a certain period. This is because the asymmetrical waveform that repeats at a constant period generates a pseudo-force sensation effect of "pulling in a certain direction," and the waveform contains many unwanted vibrations in addition to the part that contributes to the generation of force sensation, making it unsuitable for the generation of discrete force sensation.

[0028] Referring to Figures 1 to 12, in order to discretely present anisotropic vibrations and simultaneously improve the efficiency of the drive exciter 100 and reduce hardware losses, the drive exciter 100 proposed by the present invention includes a bracket 10 including a mounting fixture 11 and a guide structure 13 connected to the mounting fixture 11; a vibrating section 30 provided with a vibrable vibrator 33 that is movably connected to the guide structure 13; and a first end 41 provided opposite to the vibrating section 30 and connected to the mounting fixture 11. The drive exciter 100 includes a braking section 40 including a second end 42, and a locking section 50 including a driver 51 connected to a mounting fixture 11 and a locking material 53 connected to the output end of the driver 51. The drive exciter 100 has a first state in which the locking material 53 is in contact with the vibrating section 30, and a second state in which the locking material 53 is detached from the vibrating section 30. In the second state, the vibrating section 30 moves toward the mounting fixture 11, and the first end 41 and the second end 42 interact, separating the first end 41 and the second end 42.

[0029] In one embodiment, the mounting fixture 11 is substantially plate-shaped, and a guide structure 13 is provided on one side of the mounting fixture 11 and fixedly connected to the mounting fixture 11. The vibrating part 30 may be a linear resonator, and the vibrating part 30 is movably fitted and connected to the guide structure 13. The guide structure 13 may be provided around the damping part 40, or on one side of the guide part, but is not limited thereto. Selectively, the guide structure 13 may be one or more guide bars 131 connected to the mounting fixture 11, the vibrating part 30 is fitted onto the guide bars 131, and the guide structure 13 may be provided with rail grooves, and the vibrating part 30 is slidably provided within the rail grooves. A vibrator 33 is provided that vibrates along a direction within the vibrating part 30, and as can be understood, the vibrator 33 has a certain mass so as to have sufficient energy when vibrating.

[0030] In this embodiment, the locking part 50 is provided on one side of the vibrating part 30, and the driver 51 may be a drive device such as a linear motor, a spiral tube, a linear motor, or a rotary motor, and the driver 51 drives the locking material 53 to move closer to or away from the vibrating part 30 by translation or rotation.

[0031] The braking section 40 may be a magnet provided in separate parts or a single air spring, and the interaction between the first end 41 and the second end 42 dampens the vibrating section 30.

[0032] Specifically, in one embodiment, the following steps are required for the drive exciter 100 to generate a single complete anisotropic oscillation: Energy storage stage: An electric drive signal is input to the vibrating section 30, an excitation magnetic field is generated in the vibrating cavity, and the drive oscillator 33 constantly vibrates to store energy. At this time, the drive exciter 100 is in the first state, and the locking material 53 is in contact with the side surface of the vibrating section 30, fixing the vibrating section 30 relative to the vibration direction of the oscillator 33. Release phase: The driver 51 drives the locking material 53 to translate or rotate until the locking material 53 detaches from the vibrating part 30, and transitions the drive exciter 100 to the second state. Movement phase: The drive exciter 100 is in the second state, the vibrating part 30 is released from the restraint of the locking material 53, and moves to the braking part 40 where the mounting fixture 11 is provided by the drive of the internal vibrator 33. Damping stage: As the vibrating part 30 moves, the distance between the first end 41 and the second end 42 gradually decreases, and the interaction between them increases. The amount of movement of the vibrating part 30 is transmitted to the mounting fixture 11 as acceleration, causing anisotropic vibration and generating a tensile or force sensation along the normal direction of the contact surface between the two. Return phase: After one anisotropic vibration occurs, the vibrating part 30 separates from the mounting fixture 11, the drive exciter 100 returns to the first state and waits for the next trigger, and the anisotropic vibration stops.

[0033] To make it clear, in the above embodiment, the generation of anisotropic vibration is not due to vibration of the vibrating part 30 itself, but rather to the fitting of the damping part 40 and the vibrating part 30. That is, the damping part 40 dampens the vibrating part 30, causing anisotropic vibration, and the vibrating part 30 separates from the mounting fixture 11 and returns to the first state, and the anisotropic vibration stops.

[0034] Through the above-described steps, the drive exciter 100 can generate one anisotropic oscillation, and by repeating the above process multiple times in a certain period of time, multiple anisotropic oscillations can be generated discretely. Furthermore, by controlling the movement frequency of the vibrating part 30, the frequency at which anisotropic oscillations occur can be controlled, and by changing parameters such as the mass of the vibrating part 30 or the magnitude of the current, the magnitude of the anisotropic oscillations can be changed.

[0035] The technical solution of this application significantly expands the asymmetry of anisotropic vibration and allows for the discrete presentation of asymmetric vibration in a short time. By generating vibrations that are close to the asymmetric vibration force that actually occurs, a clear sense of force in a certain direction can be presented discretely in a short time, and since the direction of this sense of force depends on the contact direction between the damping part 40 and the vibrator 30, it is not limited to the gripping method.

[0036] In this invention, damping of the vibrating part 30 is achieved by the interaction between the first end 41 and the second end 42, resulting in anisotropic vibration. This prevents contact between the vibrating part 30 and the mounting fixture 11, reducing hardware losses. However, while solid-contact type damping tends to be short-lived, this invention achieves a longer damping time by changing parameters such as the material and shape of the first end 41 and the second end 42, resulting in diverse effects, a clear sense of directional force, and virtually no unwanted vibration.

[0037] Referring to Figures 6 and 7, in one embodiment, the first end 41 is the first magnetic material, and the second end 42 is the second magnetic material, with opposite polarities on the sides where the first and second magnetic materials face each other. In this embodiment, damping of the vibrating part 30 is achieved by the repulsive force between the first and second magnetic materials. Referring to the figures in conjunction, it is easy to see that, compared to solid materials, as the distance between the first and second magnetic materials decreases, the repulsive force between the first and second magnetic materials increases exponentially, and although they do not come into contact, the direction of the resulting anisotropic vibration becomes clearer.

[0038] Furthermore, as can be seen by comparing Figures 10, 11, and 12, vibrations due to solid contact tend to be intense and short in duration, while vibrations due to magnetic pole repulsion have regular modes, a clear direction, and a long duration.

[0039] Comparing Figure 11 and Figure 12, it can be seen that the vibration time increases and different effects occur after swapping the dimensions of the first and second magnetic materials.

[0040] Furthermore, the first magnetic material and the second magnetic material may both be permanent magnets, or of course, they may both be electromagnets, and are not limited thereto.

[0041] Referring to Figure 7, in one embodiment, a boss is provided on the surface of the vibrating part 30, a first magnetic material is provided on the boss, a yoke material 43 connected to the mounting fixture 11 is further provided on the damping part 40, a flux barrier is provided on the yoke material 43, and a second magnetic material is provided within the flux barrier. In this way, magnetic flux leakage and reinforcing magnetic field can be reduced, a better damping effect can be obtained, and the utilization rate can be improved.

[0042] In embodiments of other aspects of the present invention, the braking section 40 is an air spring with a first end 41 and a second end 42 at both ends. As the first end 41 approaches the second end 42, and the distance decreases, the space within the air spring becomes smaller and smaller, the air density increases, and consequently the pressure also increases, so that a good vibration effect can be obtained while ensuring that the first end 41 and the second end 42 do not come into contact.

[0043] Furthermore, referring to Figure 5, in one embodiment of the present invention, the mounting fixture 11 includes a mounting body 111 having a mounting groove and a through hole 111a provided in the bottom wall of the mounting groove, and a cover plate 113, the guide structure 13 is connected to the mounting body 111, the cover plate 113 seals the groove opening of the mounting groove and is detachably connected to the mounting body 111, and the second end 42 is fixedly connected to the cover plate 113 by the through hole 111a. The cover plate 113 is bolted to the mounting body 111, and the second end 42 is bonded or bolted to the cover plate 113, and in this embodiment, the braking unit 40 can be easily and quickly protected or the equipment can be maintained by removing the cover plate 113.

[0044] Referring to the figure, in one embodiment of the present invention, the locking portion 50 includes two locking members 53 located on both sides of the vibrating portion 30 to form a position-restricting space, and the driver 51 is connected to at least one of the locking members 53, where, in the first state, the vibrating portion 30 is restricted to a position within the position-restricting space.

[0045] In this embodiment, the locking member 53 may be a block-shaped body or a rod-shaped body, the vibration direction of the vibrating member 33 is set to the left-right direction, the damping part 40 is selectively provided to the right side of the vibrator 33, and two locking members 53 are provided at a left-right distance apart to form the vibration space. Here, the left locking member 53 is fixed, the driver 51 is connected to the right locking member 53, and the locking member 53 is driven to rotate or translate, switching the drive exciter 100 between a first state and a second state.

[0046] Specifically, in one embodiment of the present invention, the driver 51 is provided with a rotating shaft, the locking member 53 is a locking bar, one end of the locking member 53 is connected to the rotating shaft, and the locking member 53 is positioned such that the longitudinal direction of the locking member 53 and the extending direction of the rotating shaft form an angle. In this embodiment, the driver 51 is a rotary motor, the locking member 53 is a substantially L-shaped structure, one end of the locking member 53 is connected to the rotating shaft, and the rotating shaft rotates to move the other end of the locking member 53 closer to or further away from the vibrating part 30. When the driver 51 receives a predetermined signal, the rotating shaft drives the locking member 53 to rotate until the locking member 53 comes into contact with the housing of the vibrating part 30 or the locking member 53 detaches from the vibrating part 30. In this way, the movement of the lock 53 and the switching between the first state and the second state can be easily and simply realized.

[0047] In another embodiment of the present invention, the driver 51 drives the locking member 53 in linear motion, and the direction of movement of the locking member 53 is angled with the direction of vibration of the vibrator 33. Selectively, the driver 51 may be a linear motor, and the driver 51 includes a stator fixed to the bracket 10 and a movable element that slides with the stator and moves along a straight line, with the locking member 53 connected to the movable element. Preferably, the straight line in which the direction of movement of the locking member 53 is located and the straight line in which the direction of vibration of the vibrator 33 is located are at a 90-degree angle, so that the structure is simple and effective, and the generation and transmission of vibration are relatively clear, resulting in good effects.

[0048] Of course, the drive member 51 may be in any other structural form that can realize the above technical concept, and is not particularly limited here. Accordingly, the structure of the locking member 53 may be changed depending on the form and spatial arrangement of the drive member 51, and is not limited.

[0049] Referring to Figure 1, in one embodiment of the present invention, the bracket 10 further includes a first connecting frame 15 provided in parallel with the guide structure 13, the first connecting frame 15 being connected to the mounting fixture 11, and the driver 51 being fixed to the first connecting frame 15. The locking portion 50 further includes a stopper 55 connected to the first connecting frame 15 to form a position regulating groove 55a, the side wall of the position regulating groove 55a having a notch 55b facing the vibrating portion 30, one end of the locking material 53 connected to the driver 51 entering the position regulating groove 55a, and the other end of the locking material 53 away from the driver 51 protruding from the notch 55b, so that the locking material 53 rotates between the two opposing side walls of the notch 55b.

[0050] In this embodiment, the first connecting frame 15 is bolted to the surface of the mounting fixture 11 and has a longitudinal direction, the longitudinal direction of the first connecting frame 15 is provided parallel to the vibration direction of the vibrator 33, and the stopper 55, locking member 53 and drive element 51 are all connected to the side surface of the first connecting frame 15. Furthermore, the first connecting frame 15 is partially perforated to reduce structural weight and ensure vibration effect.

[0051] In this embodiment, the stopper 55 has a cap-like structure with no limited shape, and the groove opening of the position regulating groove 55a faces the locking material 53. Multiple notches 55b are provided in the groove wall of the position regulating groove 55a, the driver 51 is a rotary motor, and part of the locking material 53 is provided within the position regulating groove 55a, while part of it penetrates the notches 55b and protrudes from the position regulating groove 55a. As can be understood, the driver 51 can rotate the locking material 53 in the space between the side walls of the notches 55b, and when the locking material 53 comes into contact with one side wall, the locking material 53 also comes into contact with the vibrating part 30, and when the locking material 53 comes into contact with the other side wall, the locking material 53 disengages from the vibrating part 30. Adding the stopper 55 is advantageous in limiting the range of movement of the locking material 53 and offsetting the inertia of the locking material 53 to some extent, thereby improving the operating efficiency and stability of the locking material 53.

[0052] Referring to Figures 1, 3, and 4, in one embodiment of the present invention, the guide structure 13 includes at least two guide bars 131 extending along the vibration direction of the vibrator 33, the ends of which are fixed to the mounting fixture 11.

[0053] The vibrating section 30 includes a housing 31 that surrounds the vibrating space and has a sleeve 311 on its side that is movably fitted onto the guide bar 131, a vibrator 33 that is vibrably provided within the vibrating space, and two spring pieces 37 provided on both sides of the vibrator 33 along the direction of vibration of the vibrator 33, connecting the housing 31 and the end of the vibrator 33.

[0054] In this embodiment, the housing 31 includes two end caps that are positioned opposite each other and a connecting plate provided between the two end caps. Each end cap has two mounting tabs on both sides, and the mounting tabs are provided with retraction holes through which the guide bar 131 passes. The mounting tabs between the two end caps are positioned opposite each other and connected by a sleeve 311.

[0055] The vibrator 33 vibrates along a direction within the vibration space, and simultaneously with the vibration, the vibrator 33 drives the spring piece 37 to vibrate, storing the generated energy within the spring piece 37. When the housing 31 approaches the mounting fixture 11, the first end 41 and the second end 42 interact, and the stored energy is released in the form of acceleration, generating a vibration wave. Since the vibrating part 30 approaches the mounting fixture 11 from one side, the generated vibration is also on one side, exhibiting clear asymmetry. In other words, the feeling of tension in a certain direction is realistic and does not depend on the user's gripping method or sensory experience.

[0056] Furthermore, referring to Figure 4, in one embodiment of the present invention, the vibrating section 30 further includes a first link plate 34 and a second link plate 35, which are provided opposite to and fixedly connected to the housing 31, and the spring piece 37 has one end connected to the first link plate 34 or the second link plate 35 and the other end connected to the end of the vibrator 33. Selectively, the cross-section of the vibrator 33 in this embodiment is substantially parallelogram, and its vibration direction is in the left-right direction and the up-down direction perpendicular to the left-right direction located in the plane of the paper, with the first link plate 34 provided above and the second link plate 35 provided below, the upper left end of the vibrator 33 connected to the second link plate 35 and the lower right end of the vibrator 33 connected to the first link plate 34. When the vibrator 33 vibrates, its end vibrates the spring piece 37. By arranging it in this way, the elasticity of the spring piece 37 can be utilized more effectively, and the amplitudes of the vibrator 33 and the spring piece 37 can be increased equally.

[0057] Referring to Figure 1, in one embodiment of the present invention, the drive exciter 100 further includes a reset material 60, which is a spring with both ends elastically connected to the vibrating part 30 and the surface of the mounting fixture 11. By providing the reset material 60, the vibrating part 30 can be smoothly reset after the braking stage, thereby restoring the drive exciter 100 to the first state.

[0058] Of course, the resetting material 60 is not limited to a spring, but may be any other structure that can reset the vibrating part 30.

[0059] In another embodiment of the present invention, the drive exciter 100 includes two opposing mounting fixtures 11, two braking parts 40, and two locking parts 50, wherein both ends of the guide structure 13 are connected to the two mounting fixtures 11, the two braking parts 40 are provided opposite to the two mounting fixtures 11, the two locking parts 50 are provided in parallel on both sides of the vibrating part 30, one driver 51 is connected to one locking member 53, each locking member 53 is provided between the vibrating part 30 and the mounting fixture 11, forming a position-restricting space, where, in the first state, the vibrating part 30 is restricted to a position within the position-restricting space.

[0060] In this embodiment, the two locking members 53 may be provided on the same side or on different sides, and the two locking members 53 are movable, but in the second state, only one locking member 53 moves and detaches from the vibrating part 30. For example, when the right locking member 53 moves, the left locking member 53 is fixed and the vibrating part 30 moves to the right, and when the left locking member 53 moves, the right locking member 53 is fixed and the vibrating part 30 moves to the left. That is, in the second state, the vibrating part 30 can approach only one of the damping parts 40, and the anisotropic vibrations generated when the vibrating part 30 is fitted to each of the two damping parts 40 are reversed. In this embodiment, the drive exciter 100 can realize movement of the vibrating part 30 in different directions and can present two opposite anisotropic vibrations, and the above two vibrations do not exist simultaneously.

[0061] The present invention further relates to an electronic device including a drive exciter 100 of any one of the above embodiments, wherein the specific structure of the drive exciter 100 is described with reference to the above embodiments, and since this electronic device employs all the technical solutions of all the above embodiments, it has at least all the beneficial effects of the technical solutions of the above embodiments, and therefore will not be described further here.
