Description

Technical Field

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

Background Art

[0002] Conventional vibration devices constantly produce asymmetric vibrations to create an illusion of a force acting "as if in a certain direction." However, to cause such an illusion, not only is the gripping method of the device limited by shearing the skin, but it is also necessary to limit the vibration frequency to a range where it is easy to perceive, and the stimulus must be sustained for a certain period of time. The equivalent force felt by this method is small, and due to the extra vibrations, it is difficult for the user to obtain a clear sense of direction.

[0003] As a means of reproducing the sense of force, there is a method of obtaining anisotropic vibration by releasing the braking of a moving vibrating part in a fixed state. However, the vibrating part constantly vibrates and accelerates when fixed, extra vibrations flow from the housing, generating a slight noise, which somewhat affects the vibration effect of the anisotropic vibration generated thereby and the user experience.

Best Mode for Carrying Out the Invention

[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention while combining the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained on the premise that those skilled in the art do not pay creative efforts all belong to the protection scope of the present invention.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement between components in a specific posture (as shown in the drawings). When the specific posture changes, the directional indications also change accordingly.

[0026] In addition, the descriptions related to "first", "second", etc. in the present invention are only used for the purpose of description, and should not be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Thus, the features limited to "first" and "second" can explicitly or implicitly include at least one of the features. Also, the technical solutions between the embodiments can be combined with each other, but it must be based on what can be realized by those skilled in the art. If there is a contradiction or inability to realize in the combination of technical solutions, such a combination of technical solutions should be considered non-existent and not included in the protection scope required by the present invention.

[0027] "Anisotropic vibration", also called "asymmetric vibration", can be realized by inputting an asymmetric signal into a vibration device such as a vibration motor, etc., and generating a pulling feeling in a certain direction for the user holding the vibration device. A vibration device that can realize anisotropic vibration is often used in devices such as game controllers, and provides good force feedback to the user through asymmetric vibration.

[0028] In the vibration device according to the technical solution of the present application, the so-called "discrete" is a concept relative to "continuous". For example, the vibration motor continuously outputs continuous vibration to the vibration device, allowing the user to feel a continuous vibration sensation or tensile sensation for a certain period of time, resulting in continuous vibration. On the other hand, if the vibration device outputs vibration in a clear direction at intervals within a certain period of time once or multiple times, it becomes discrete anisotropic vibration.

[0029] However, as shown in FIGS. 13 and 14, both figures show that the waveforms are repeated at a certain period. This is because a pseudo-force sense effect of "pulling in a certain direction" is generated by an asymmetric waveform that is repeated at a certain period. Obviously, there are many unnecessary vibrations in the waveforms other than the parts that contribute to the generation of the force sense, and it is not suitable for the generation of discrete force sense.

[0030] Referring to FIGS. 1 to 17, the present invention proposes a drive excitation device 1000 including an even number of drive exciters. Each drive exciter includes a housing forming an excitation space, a vibration part 30 movably provided in the excitation space and provided with a vibrator 33 capable of vibrating along a first direction, a braking part 40 fixed in the excitation space along the first direction and provided facing the vibration part 30, and a locking part 50 including a driver 51 connected to the housing 31 and a locking material 53 connected to the output end of the driver 51. The drive exciter has a first state in which the locking material 53 is in contact with the vibration part 30 and a second state in which the locking material 53 is detached from the vibration part 30. In the first state, an even number of housings are sequentially connected along the first direction, and the vibration directions of the vibrators 33 of two adjacent drive exciters are opposite. An even number of drive exciters sequentially enter the second state. In the second state, the vibration part 30 moves toward the braking part 40 and comes into contact with the braking part 40.

[0031] As shown in FIG. 15, the third waveform from top to bottom in the figure represents the vibration signal. The portion selected by the dotted line frame is the after-vibration generated when the vibrating part 30 in the first state is fixed. After that, it is the anisotropic vibration generated when the vibrating part 30 is braked by the braking part 40 in the second state. It can be intuitively understood that the signal of the after-vibration has a considerably higher intensity compared to the signal of the anisotropic vibration.

[0032] In order to present discretely to achieve clear and distinct anisotropic vibration, while suppressing unnecessary vibration leaking from the housing, in the present application, an even number of housings are sequentially connected along the first direction, and the vibration directions of the vibrators 33 of two adjacent drive exciters are opposite.

[0033] Specifically, in one embodiment, the first direction is the horizontal direction, the excitation space has a certain length in the first direction, the braking part 40 can be fixed in the excitation space along the first direction, and the vibrating part 30 can be moved a certain distance along the first direction. The vibrating part 30 may be a linear resonator, and a vibrator 33 that vibrates along a direction in the vibrating part 30 is provided. As can be understood, the vibrator 33 has a certain mass so as to have sufficient energy during vibration.

[0034] The vibrating part 30 can be fitted into the inner wall of the excitation space with a clearance, or a guide structure 13 is provided in the housing, and the vibrating part 30 is slidably fitted and connected to the guide structure 13 for more stable movement.

[0035] In this embodiment, a locking part 50 is provided on one side of the vibrating part 30. Here, the driver 51 may be a driving device such as a linear motor, a solenoid, a linear motor, and a rotary motor. The driver 51 drives the locking material 53 to move closer to or away from the vibrating part 30 by translating or rotating relative to the vibrating part 30.

[0036] Referring to FIGS. 7 to 11 in combination, the following steps are required for the drive exciter to generate one complete anisotropic vibration: Energy storage stage: Referring to FIG. 7, an electric drive signal is input to the vibrating part 30, an excitation magnetic field or electric field is generated in the vibration cavity to drive the vibrator 33 to continuously accelerate and vibrate to store energy. At this time, the drive exciter is in the first state, and the locking material 53 abuts against the side surface of the vibrating part 30 to relatively fix the vibrating part 30 in the vibration direction of the vibrator 33. Release stage: Referring to FIG. 8, until the locking material 53 disengages from the vibrating part 30, the driver 51 drives the locking material 53 to translate or rotate, and the drive excitation enters the second state. Moving stage: Referring to FIG. 9, at this time, the drive exciter is in the second state, the vibrating part 30 disengages from the restraint of the locking material 53, and driven by the internal vibrator 33, the fixture 11 moves to the braking part 40 provided. Braking stage: Referring to FIG. 10, the braking part 30 abuts against the braking part 40. The braking part 30 receives the energy generated by the vibration of the vibrator 33 to generate anisotropic vibration, and generates a tensile feeling or a force feeling in the direction normal to the contact surface of both. Return stage: Referring to FIG. 11, after one anisotropic vibration occurs, the vibrating part 30 leaves the braking part 40, the drive exciter returns to the first state and waits for the next trigger, and the anisotropic vibration stops.

[0037] As can be understood, in the above embodiment, the generation of anisotropic vibration is not caused by the vibration of the vibrating part 30 itself, but is caused by the fitting of the braking part 40 and the vibrating part 30. That is, the braking part 40 brakes the vibrating part 30 to generate anisotropic vibration. After the vibrating part 30 leaves the braking part 30, the vibration gradually decreases and stops.

[0038] After going through the above several steps, the driving exciter can generate one anisotropic vibration. By circulating the above process multiple times within a certain period of time, multiple anisotropic vibrations can be discretely generated. Further, by controlling the moving frequency of the vibrating part 30, the frequency at which the anisotropic vibration occurs can be controlled. By changing parameters such as the mass or the magnitude of the current of the vibrating part 30, the magnitude of the energy stored by the vibrating part during the energy storage stage, and further the magnitude of the anisotropic vibration can be changed.

[0039] Here, in one embodiment, the driving device includes two connected driving exciters. During the energy storage stage, since the vibrators 33 of the two driving exciters move in opposite directions, the unnecessary vibrations during the energy storage stage are offset. Specifically, referring to and comparing FIGS. 15 and 16, the third waveform from top to bottom in FIG. 15 is the vibration waveform when a single driving exciter acts. Similarly, FIG. 16 is the vibration waveform diagram when the technical solution of this embodiment is adopted. The parts selected by the dotted frames of both are the vibration waveforms during the energy storage stage. By comparison, it is clear that the after-vibrations during the energy storage stage are well suppressed when the technical solution of the present application is adopted.

[0040] Furthermore, referring to FIG. 17, the anisotropic vibration of this embodiment is generated as follows: The drive signal is input to the vibrating unit 30 to indicate the phase state of the excitation signal that drives the movement of the vibrator 33. The periods of the drive signals of the first drive exciter 100 and the second drive exciter 200 are the same, but since the phases of the two are shifted by half a period, the vibration directions of the two vibrators 33 are opposite. With the continuous input of the drive signal, the energy possessed by the vibrator 33 gradually increases. In an ideal state, the composite waveform in which the two vibrators 33 vibrate in opposite directions becomes substantially a straight line. When accelerating to a certain extent, the drive signal is cut off, and the first drive exciter 100 and the second drive exciter 200 sequentially enter the second state, and the time difference is about half a period. Thereby, when the vibrating unit 30 abuts against the braking unit 40, it is ensured that the first drive exciter 100 and the second drive exciter 200 can generate vibrations in the same direction but in opposite directions. Thereafter, the two vibrating units 30 are sequentially braked by the corresponding braking unit 40, generating two anisotropic vibrations with a phase shift of about half a period. However, when the period is sufficiently short, the two anisotropic vibrations can be perceived as one distinct vibration.

[0041] The technical solution of the present application is to switch the drive exciter between the first state 100 and the second state by a lock member 53 provided movably. In the first state, the vibrating unit 30 is relatively fixed. In the second state, the vibrating unit 30 abuts against the braking unit 40, and the braking unit 40 brakes the vibrating unit 30 to generate anisotropic vibration. Since the generation of this anisotropic vibration requires the fitting of the braking unit 40 and the vibrating unit 30, the frequency at which vibration occurs depends on the frequency at which the vibrating unit 30 moves and abuts against the braking unit 40. Therefore, when the lock member 53 continuously moves and continuously switches between the first state and the second state, the vibrating unit 30 intermittently abuts against the braking unit 40, and thus anisotropic vibration can be generated discretely.

[0042] The technical solution of the present application can greatly expand the asymmetry of the anisotropic vibration and discretely present the asymmetric vibration in a short time. By generating vibrations close to the actually occurring asymmetric vibration force, a clear sense of force in a certain direction can be discretely presented in a short time. Since the direction of this sense of force depends on the abutting direction between the braking unit 40 and the vibrator 30, it is no longer limited to the gripping method.

[0043] Note that the driving excitation device 1000 of the present application employs an even number of connected driving exciters. By vibrating the vibrators 33 of two adjacent driving exciters in opposite directions, unnecessary vibrations generated during the energy storage stage are eliminated, and the generated anisotropic vibrations are made purer, thereby presenting a force feedback with a clearer sense of direction, suppressing the generation of noise to a certain extent, and improving the operating quality and user experience of the driving excitation device 1000.

[0044] Referring to FIG. 12, in one embodiment of the present invention, the centers of an even number of vibrators 33 are coaxially provided. In one embodiment, the driving excitation device includes a first driving exciter 100 and a second driving exciter 200. The first driving exciter 100 has the same internal structure as the second driving exciter 200, and both are provided with one vibrating part 30, two braking parts 40 on both sides, and a locking part 50. The first driving exciter 100 and the second driving exciter 200 are connected and provided along a first direction, and the housings of both are abutted or adhered. Of course, the connection method is not limited as long as vibration can be transmitted.

[0045] At the same time, two vibrators 33 move towards each other or move away from each other, and the centers of the two vibrators 33 are on the same straight line, so that the vibrations caused by the two can be relatively completely offset, and a better suppression effect on the unnecessary vibrations in the energy storage stage can be realized.

[0046] Thus, in some other embodiments of the present invention, 4, 8 or more driving exciters can be provided in the driving excitation device 1000, and the moving directions of the vibrators 33 of two driving exciters are opposite at the same time.

[0047] In embodiments of other aspects of the present application, when more driving exciters are provided in the driving excitation device 1000, a plurality of vibrators 33 can be provided with a shift, or some can be coaxially arranged and some can be provided with a shift, so as to obtain various vibration effects.

[0048] Referring to FIGS. 1 and 12, in one embodiment of the present invention, the housing includes a housing body and a bracket 10. An even number of housing bodies are sequentially connected along a first direction. The bracket 10 is provided in an excitation space. The bracket 10 includes a fixture 11 and a guide structure 13 connected to the fixture 11. The fixture 11 is connected to at least one side of the housing body along the first direction. A braking part 40 and a locking part 50 are connected to the fixture 11, and a vibrating part 30 is movably connected to the guide structure 13.

[0049] In this embodiment, the housing 31 is not limited in shape and forms an excitation space so that the vibrating part 30 can move a distance until it collides with the braking part. The fixture 11 is substantially in the shape of a plate. One surface thereof is fixedly connected to the inner wall of the housing 31. The guide structure 13 is provided on one side of the fixture 11 and fixedly connected to the fixture 11. The vibrating part 30 is movably fitted and connected to the guide structure 13. The braking part 40 is fixed to the surface of the fixture 11 facing the vibrating part 30. The guide structure 13 may be provided to surround the braking part 40 or may be provided on one side of the braking part 40, which is not limited herein.

[0050] Optionally, the guide structure 13 may be one or more guide bars 131 connected to the fixture 11. The vibrating part 30 is fitted into the guide bar 131. A rail groove may be provided in the guide structure 13, and the vibrating part 30 is slidably provided in the rail groove. By providing the fixture 11 and the guide structure 13, structural support and guidance are provided to the braking part 40 and the position regulating part, making the internal structure of the drive exciter more stable and the movement of the vibrating part 30 smoother and faster.

[0051] Referring to FIGS. 1, 4, and 5, in one embodiment of the present invention, the vibrating part 30 is a housing 31 connected to the guide structure 13 and surrounding the vibration space, and the housing 31 in which the vibrator 33 is provided so as to be vibratable within the vibration space; two elastic members 37 provided on both sides along the first direction of the vibrator 33 and connecting the housing 31 and the vibrator 33; and two sets of magnetic materials 36 fixed within the vibration space and provided on opposite sides perpendicular to the first direction of the vibrator 33, each set of magnetic materials 36 having opposite magnetic poles provided on the side facing the vibrator 33. A coil is provided on the vibrator 33. In the first state, the current directions of the coils of two adjacent drive exciters are opposite.

[0052] In this embodiment, the housing 31 includes two end caps provided opposite to each other and a connecting plate provided between the two end caps. Two mounting ears are provided symmetrically or on the same side of each end cap, and a retraction hole through which the guide bar 131 penetrates is provided in the mounting ear. The mounting ears between the two end caps are provided opposite to each other and are connected by a sleeve 311.

[0053] The vibrator 33 vibrates along a certain direction within the vibration space. The vibrator 33 drives the elastic member 37 to vibrate simultaneously with the vibration, stores the generated energy in the elastic member 37, and when the housing 31 abuts against the braking part 40, the stored energy is released to the braking part 40 to generate a vibration wave. Since the vibrating part 30 abuts against the braking part 40 from one side, the generated vibration is also on one side and has an obvious asymmetry. That is, the sense of tension in a certain direction is real and does not depend on the user's gripping method or sensory experience.

[0054] Referring to FIG. 12, in this embodiment, each set of magnetic materials 36 may be substantially U-shaped independent permanent magnets with opposite polarities at both ends facing the vibrator 33, and the polarities of the opposing surfaces of the two sets of permanent magnets are also opposite. When an electric current is passed through the coil to generate a magnetic field, the vibrator 33 moves in a certain direction due to the interaction between the magnetic poles. As can be understood, when the direction of the current changes, the direction of the magnetic field of the coil changes, so the moving direction of the vibrator 33 also changes. Therefore, when the current directions of the coils of the vibrators 33 of two adjacent drive exciters are opposite, the moving directions of the vibrators 33 are also opposite.

[0055] Of course, each set of magnetic materials 36 may further include two permanent magnets with opposite polarities on the surfaces facing the vibrator 33.

[0056] In another embodiment, a coil is fixed in the vibration space, a permanent magnet is embedded in the vibrator 33, and when an electric current flows through the coil to generate a magnetic field, the vibrator 33 vibrates under the action of the magnetic field. When the direction of the current changes, the moving direction of the vibrator 33 changes.

[0057] The vibration driving form of the vibrator 33 is not limited to the above embodiments, and is not particularly limited as long as it can drive the vibrator 33 to move and at the same time regularly and periodically change its moving direction.

[0058] In one embodiment of the present invention, the vibrating part 30 further includes a first link plate 34 and a second link plate 35 which are oppositely provided and fixedly connected to the housing 31, and the elastic member 37 is a spring piece with 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.

[0059] Optionally, referring to FIG. 5, the cross-section of the vibrator 33 of this embodiment is a substantially parallelogram. The first direction is the left-right direction, located in the plane of the paper, and the vertical direction perpendicular to the first direction. The first link plate 34 is provided above, the second link plate 35 is provided below, the upper left end of the vibrator 33 is connected to the second link plate 35, and the lower right end of the vibrator 33 is connected to the first link plate 34. When the vibrator 33 vibrates, its end vibrates the spring piece. By providing it in this way, the elasticity of the spring piece can be better utilized, and the amplitudes of the vibrator 33 and the spring piece can be increased equally.

[0060] Referring to FIG. 1, in one embodiment of the present invention, the bracket 10 further includes a first connection frame 15 provided in parallel with the guide structure 13. The first connection frame 15 is connected to the fixture 11, and the driver 51 is fixed to the first connection frame 15. A rotating shaft is provided on the driver 51. The locking member 53 is a locking bar. One end of the locking member 53 is connected to the rotating shaft, and the longitudinal direction of the locking member 53 and the extending direction of the rotating shaft are provided at an angle.

[0061] In this embodiment, the first connection frame 15 is bolt-connected to the surface of the fixture 11 and has a longitudinal direction. The longitudinal direction of the first connection frame 15 is provided parallel to the first direction. Both the locking member 53 and the driver 51 are connected to the side surface of the first connection frame 15. Further, the first connection frame 1515 is partially engraved with a watermark in order to ensure structural weight reduction and vibration effect.

[0062] Optionally, referring to FIGS. 2 and 3, in this embodiment, the driver 51 is a rotating motor, and the locking member 53 is a substantially L-shaped structure. One side of the locking member 53 is connected to the rotating shaft, and the rotating shaft rotates to move the other side of the locking member 53 closer to or away from the vibrating portion 30. When the driver 51 receives a predetermined signal, the rotating shaft drives the locking member 53 to rotate until the locking member 53 abuts against the housing of the vibrating portion 30 or the locking member 53 disengages from the vibrating portion 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.

[0063] In an embodiment of another aspect of the present invention, the driver 51 drives the locking member 53 in a linear movement, and is provided such that the moving direction of the locking member 53 forms an angle with the first direction. Optionally, the driver 51 may be a linear motor. The driver 51 includes a stator fixed to the bracket 10 and a mover that slidably engages with the stator and moves along a straight line, and the locking member 53 is connected to the mover. Preferably, it is provided such that the straight line in which the moving direction of the locking member 53 is located and the straight line in which the vibrating direction of the vibrator 33 is located form a 90-degree angle. In this way, the structure is simple and effective, and the generation and transmission of vibration are also relatively clear, having a good effect.

[0064] Of course, the driving member 51 may be in other structural forms capable of realizing the above technical concept, and is not particularly limited herein. Accordingly, the structure of the locking member 53 may be changed according to the form and spatial arrangement of the driving member 51, and is not limited.

[0065] Referring to FIGS. 2 and 3, in an embodiment of the present invention, the locking portion 50 further includes a stopper 55 connected to the first connection frame 15 to form a position regulating groove 55a. Notches 55b facing the vibrating portion 30 are formed in the side walls of the position regulating groove 55a. One end of the locking member 53 connected to the driver 51 enters the position regulating groove 55a, and one end of the locking member 53 away from the driver 51 protrudes from the notch 55b. The locking member 53 rotates and moves between two opposing side walls of the notch 55b.

[0066] Referring to FIG. 3, the stopper 55 has a structure like a cap with an unrestricted shape, and the groove opening of the position regulating groove 55a faces the locking member 53. In this embodiment, a plurality of notches 55b are provided on the groove wall of the position regulating groove 55a. The driver 51 is a rotary motor. A part of the locking member 53 is provided in the position regulating groove 55a, and a part thereof penetrates through the notch 55b and protrudes from the position regulating groove 55a. As can be understood, the driver 51 can rotationally drive the locking member 53 into the space between the two side walls of the notch 55b. When the locking member 53 abuts against one of its side walls, the locking member 53 also just abuts against the vibrating part 30. When the locking member 53 abuts against the other side wall, the locking member 53 disengages from the vibrating part 30. Adding the stopper 55 to limit the movement range of the locking member 53 is advantageous for offsetting the inertia of the locking member 53 to a certain extent, and improving the operating efficiency and stability of the locking member 53.

[0067] In one embodiment of the present invention, the guide structure 13 includes at least two guide bars 131 extending along a first direction. The ends of the guide bars 131 are fixed to the fixture 11. The vibrating part 30 further includes a housing 31 provided with at least two sleeves 311 on the side surface. One sleeve 311 is movably fitted onto one guide bar 131. The guide bar 131 is provided around the braking part 40 and may be provided on one side of the braking part 40. A bearing is provided in the sleeve 311, and the vibrating part 30 can approach or move away from the braking part 40 along the guide bar 131. By providing the guide bar 131, structural support and guidance can be provided to the position regulating part, the internal structure of the driving exciter can be made more stable, and the movement of the vibrating part 30 can be made smoother and faster.

[0068] Furthermore, referring to FIG. 6, in one embodiment of the present invention, the fixture 11 includes a mounting body 111 provided with 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 removably connected to the mounting body 111. The braking part 40 is fixedly connected to the cover plate 113 through the through hole 111a. The cover plate 113 is bolt-connected to the mounting body 111, and the braking part 40 is adhesively or bolt-connected to the cover plate 113. Due to the interaction between the vibrating part 30 and the braking part 40, hardware loss cannot be avoided. In this embodiment, by removing the cover plate 113, the replacement of the braking part 40 or the maintenance of the device can be easily and quickly realized.

[0069] Referring to FIGS. 7 to 11, in one embodiment of the present invention, the locking part 50 includes two locking members 53 located on both sides of the vibrating part 30 to form a position regulation space, and the driver 51 is connected to at least one locking member 53. Here, in the first state, the vibrating part 30 is position-regulated within the position regulation space. In this embodiment, the locking member 53 may be a block-shaped body or a rod-shaped body. Optionally, the braking part 40 is provided on one side along the first direction of the vibrator 33, and the two locking members 53 are provided at intervals so as to form the above-mentioned vibration space. That is, in this embodiment, the driving exciter is provided with the braking part 40 provided on one side. Here, one side of the locking member 53 is fixed, the driver 51 is connected to the other side of the locking member 53, and the locking member 53 is driven to rotate or translate, so as to switch the driving exciter between the first state and the second state.

[0070] The fitting of the vibrating part 30 and the braking part 40 can generate anisotropic vibration in one direction, and even-numbered driving exciters with the braking parts 40 provided in the same direction or intersecting in the opposite direction can be fitted to generate various vibration effects.

[0071] For example, in one embodiment, the braking parts 40 of an even number of drive exciters are all provided on the inner side thereof. When the drive exciters are sequentially excited, a plurality of vibrations in the same direction are generated. In another embodiment, the braking parts 40 of some of the drive exciters are provided on one side along the first direction, and the braking parts 40 of some other drive exciters are provided on the other side. When the drive exciters are sequentially excited, vibrations in different directions are superimposed, and through calculation or control, vibration force sensations with different time lengths, intensities, and levels can be discretely generated in an ideal state.

[0072] Referring to FIGS. 1 and 12, in another embodiment of the present invention, each drive exciter includes two braking parts 40 and two locking parts 50. The two braking parts 40 are fixed to opposite sides of the vibrating part 30 along the first direction. Each locking part 50 includes one driver 51 and one locking material 53. The two locking materials 53 are respectively provided on both sides of the vibrating part 30 along the first direction, and each locking material 53 is provided between the vibrating part 30 and the braking part 40 to form a position regulation space. Here, in the first state, the vibrating part 30 is position-regulated within the position regulation space.

[0073] In this embodiment, at least one second connection frame 17 is provided between the two fixtures 11, and both ends of the second connection frame 17 are respectively connected to the fixtures 11 to ensure the structural stability. The locking material 53 is provided on the side of the driver 51 along the first direction. Observing the drive exciter along the first direction, the two locking materials 53 may be provided together on one side of the vibrating part 30, or may be symmetrically provided on both opposite sides of the vibrating part 30. And both of the two locking materials 53 are movable, but in the second state, one of the locking materials 53 moves and detaches from the vibrating part 30. For example, taking the direction along the first direction as the left-right direction, when the right locking material 53 moves, the left locking material 53 is fixed, and the vibrating part 30 moves to the right. When the left locking material 53 moves, the right locking material 53 is fixed, and the vibrating part 30 moves to the left. That is, in the second state, the vibrating part 30 can only approach one of the braking parts 40, and the anisotropic vibrations generated when the vibrating part 30 fits with the two braking parts 40 respectively are reversed.

[0074] That is, in this embodiment, the drive exciter can realize the movement of the vibrating part 30 in different directions, and can further present two anisotropic vibrations in opposite directions. Moreover, the above two vibrations do not exist simultaneously. On the other hand, when an even number of drive exciters are fitted, various vibration effects can be obtained by controlling to sequentially open the locking members 53 on the same side or by controlling to alternately open the locking members 53 on different sides.

[0075] Optionally, the guide structure 13 is a guide bar 131. A plurality of guide bars 131 may be provided, and a plurality of locking parts 50 may also be provided in parallel. The guide bar 131 and the locking part 50 intersect in the circumferential direction of the vibrating part 30 with an interval therebetween, and the number of locking members 53 provided on both sides of the vibrating direction of the vibrating part 30 is the same and the positions are symmetric, ensuring that the force is uniform and the structure is stable.

[0076] Referring to FIG. 1, in one embodiment of the present invention, the drive exciter further includes a reset member 60 which is a spring whose both ends are elastically connected to the vibrating part 30 and the housing respectively. By providing the reset member 60, the vibrating part 30 can be smoothly reset after the braking stage, thereby restoring the drive exciter to the first state. Of course, the reset member 60 is not limited to a spring, and other structures capable of resetting the vibrating part 30 may also be used.

[0077] Optionally, in order to protect the hardware and realize good vibration transmission, a buffer member 39 towards the braking part 40 is provided at the end of the vibrating part 30 along the first direction. The buffer member 39 can be made of an elastic material such as rubber.

[0078] Optionally, in one embodiment of the present invention, the braking part 40 is a spring, or the braking part 40 is rubber, or the braking part 40 is foam, or the braking part 40 is configured such that at least two of a spring, rubber, and foam are provided in series or in parallel, that is, two or three of a spring, rubber, and foam are provided with their ends connected in sequence so as to obtain a good braking effect, or are provided in parallel so as to brake the vibrating part 30 and ensure the structural stability.

[0079] Two platens to which a spring, rubber, and foam are connected in parallel or in series may be separately provided for the braking part 40. One platen is connected to the housing, and the other platen is used to abut against the vibrating part 30. Thereby, the braking part 40 can obtain a good braking effect and a vibration absorption and transmission effect.
