Abstract
Description
Technology Field
[0001] The present invention relates to the field of vibration device technology, and in particular to driving excitation devices and electronic devices. Background Technology
[0002] Conventional vibration devices continuously generate asymmetric vibrations to create the illusion of a force acting "directed in a specific direction." However, since producing this illusion requires shear deformation of the skin, it not only restricts the gripping method of the device but also limits the vibration frequency to an easily detectable range and necessitates sustaining the stimulation for a fixed period. The equivalent force perceived in this way is small, and unnecessary vibrations also make it difficult for the user to obtain a distinct sense of direction.
[0003] As a means of reproducing a sense of force, there is a method to obtain anisotropic vibration by braking a moving vibrating part that has been released from its fixed state; however, since the vibrating part continuously vibrates and accelerates when fixed, causing unnecessary vibrations to be transmitted outside the shell and generating some noise, this affects the vibration effect of the generated anisotropic vibration and the user experience to some extent.

The objectives, functional features, and advantages of the present invention will be further explained with reference to the drawings and embodiments. Specific details for implementing the invention
[0048] Below, the technical means of the embodiment of the present invention will be clearly and completely explained with reference to the drawings of the embodiment of the present invention; of course, the described embodiment is only a part of the present invention, not the whole. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative effort fall within the scope of protection of the present invention.
[0049] In embodiments of the present invention, it should be noted that all direction indicators (e.g., up, down, left, right, front, back...) are used only to interpret the relative positional relationship, movement, etc., between each component in a specific posture (as shown in the drawings), and that if this specific posture changes, the corresponding direction indicator also changes accordingly.
[0050] Furthermore, designations such as "first," "second," etc., mentioned in this invention are used solely for illustrative purposes and should not be understood as indicating or implying their relative importance, or as implicitly indicating the number of designated technical features. Accordingly, the features limited to "first" and "second" may explicitly or implicitly include at least one such feature. Additionally, while the technical solutions of each embodiment may be combined with one another, this must be based on what can be implemented by a person skilled in the art; if the combination of technical solutions is contradictory or cannot be implemented, such combination of technical solutions shall be deemed non-existent or not to fall within the scope of protection required by this invention.
[0051] So-called "anisotropic vibration," also known as "asymmetric vibration," causes a user gripping a vibration device, such as a vibration motor, to feel as if they are being pulled in a specific direction by inputting an asymmetric signal to the vibration device. Therefore, vibration devices capable of implementing anisotropic vibration are commonly used in devices such as game controllers to provide good force feedback to the user through asymmetric vibration.
[0052] In the vibration device related to the technical solution of the present application, the so-called "discrete" is a concept relative to "continuous." For example, if a vibration motor vibrates continuously to output continuous vibration to a vibration device, causing a user to feel a shaking or pulling sensation that lasts for a certain period of time, this is continuous vibration; and if the vibration device outputs one or several distinct vibrations in a specific direction at intervals within a certain period of time, this is discrete anisotropic vibration.
[0053] However, as shown in FIGS. 13 and 14, both graphs show waveforms that repeat at a specific period, which is because the "pulled in a specific direction" pseudo-force sensation effect is generated by an asymmetric waveform that repeats at a constant period, and clearly, since the waveform contains a lot of unnecessary vibration in addition to the parts that help generate the force sensation, this method is not suitable for generating discrete force sensations.
[0054] Referring to FIGS. 1 to 17, the present invention provides a driving excitation device (1000), wherein the driving excitation device (1000) includes an even number of driving exciters, each driving exciter includes a shell, a vibrating part (30), a braking part (40), and a locking catch part (50), wherein the shell forms an excitation space, the vibrating part (30) is movably installed within the excitation space, and the vibrating part (30) is equipped with a vibrating member (33) capable of vibrating along a first direction, the braking part (40) is fixed within the excitation space along the first direction and installed toward the vibrating part (30), and the locking catch part (50) includes a driving member (51) connected to a housing (31) and a locking catch member (53) connected to the output end of the driving member (51). The driving excitation device has a first state in which the locking catch member (53) comes into contact with the vibration unit (30) and a second state in which the locking catch member (53) comes out of the vibration unit (30). In the first state, an even number of shells are connected sequentially along the first direction, and the vibration directions of two adjacent driving excitation device vibration members (33) are opposite to each other. The even number of driving excitation devices sequentially enter the second state. In the second state, the vibration unit (30) moves toward the braking unit (40) and comes into contact with the braking unit (40).
[0055] As shown in FIG. 15, the third waveform from top to bottom in the drawing represents a vibration signal, and the part enclosed by the dotted line is a residual vibration generated when the vibrating part (30) in the first state is fixed, followed by an anisotropic vibration generated when the vibrating part (30) in the second state is braked by the braking part (40). Through this, it is relatively intuitively possible to conclude that the residual vibration signal is still significantly stronger than the anisotropic vibration signal.
[0056] In order to discretely produce distinct and clear anisotropic vibrations while suppressing unnecessary vibrations leaking out of the shell, in this application, an even number of shells are connected sequentially along a first direction, and the vibration directions of the vibration members (33) of two adjacent driving exciters are opposite to each other.
[0057] Specifically, in one embodiment, the first direction is a horizontal direction, and the excitation space has a constant length in the first direction, so that the braking member (40) is fixed within the excitation space along the first direction and the vibrating member (30) can move a constant distance along the first direction. The vibrating member (30) may be a linear resonator, and a vibrating member (33) that vibrates along a specific direction is installed within the vibrating member (30), and it can be understood that the vibrating member (33) has a constant mass so that it can have sufficient energy when vibrating.
[0058] The vibrating part (30) and the inner wall of the space here can be fitted into a gap, or a guide structure (13) is installed inside the shell, and the vibrating part (30) and the guide structure (13) are slidably matched and connected to allow for more stable movement.
[0059] In this embodiment, the locking catch member (50) is installed on one side of the vibration member (30), and the driving member (51) may be a driving device such as a linear motor, a spiral tube, a linear motor, and a rotary motor, and the driving member (51) drives the locking catch member (53) to translate or rotate so as to move closer to or further away from the vibration member (30).
[0060] Referring to FIGS. 7 through 11 in combination, the following steps are required for the driving excitation to generate one complete anisotropic oscillation.
[0061] Energy storage step: Referring to FIG. 7, an electrical driving signal is input to the vibrating part (30), and an excitation magnetic field or electric field is generated within the vibrating cavity to drive the vibrating member (33) to continuously accelerate vibration and store energy. At this time, the driving excitation is in a first state, and the locking catch member (53) is in contact with the side of the vibrating part (30) so that the vibrating part (30) is fixed relatively in the direction of vibration of the vibrating member (33).
[0062] Release step: Referring to FIG. 8, the driving member (51) drives the locking catch member (53) to translate or rotate until the locking catch member (53) is detached from the vibrating member (30), and the driving excitation is switched to a second state.
[0063] Movement step: Referring to FIG. 9, at this time the driving excitation is in the second state, and the vibration part (30) moves out of the restraint of the locking catch member (53) and moves to the braking part (40) installed on the mounting member (11) under the driving of the internal vibration member (33).
[0064] Braking step: Referring to FIG. 10, the vibrating part (30) is in contact with the braking part (40), and the braking part (40) receives energy generated by the vibration of the vibrating member (33) and generates anisotropic vibration, creating a pulling sensation or force along the normal direction of the contact surface between the two.
[0065] Return phase: Referring to FIG. 11, after one anisotropic vibration occurs, the vibrating part (30) is detached from the braking part (40), and the driving excitation returns to the first state to wait for the next trigger, and the anisotropic vibration is stopped.
[0066] In the above embodiment, the generation of anisotropic vibration is not caused by the vibration of the vibration part (30) itself, but by the cooperation of the braking part (40) and the vibration part (30). That is, the braking part (40) brakes the vibration part (30) to generate anisotropic vibration, and it can be understood that when the vibration part (30) is separated from the braking part (40), the vibration gradually decreases and stops.
[0067] After going through the above steps, the driving excitation can generate a single anisotropic vibration, and can generate multiple anisotropic vibrations discretely by cycling the above process multiple times within a certain time. In addition, the frequency of anisotropic vibration generation can be controlled by controlling the movement frequency of the vibration unit (30), and the magnitude of the anisotropic vibration can be changed by changing the energy magnitude of the vibration unit stored in the energy storage stage by changing parameters such as the mass or current magnitude of the vibration unit (30).
[0068] Here, in one embodiment, the driving device includes two driving exciters connected to each other, and since the vibration members (33) of the two driving exciters move in opposite directions in the energy storage stage, unnecessary vibrations in the energy storage stage can be canceled out. Specifically, by comparing FIG. 15 and FIG. 16, the third waveform from top to bottom in FIG. 15 is a vibration waveform when a single driving exciter is actuated, and similarly, FIG. 16 shows a vibration waveform diagram using the technical solution of the present embodiment, and the part enclosed by the dotted line in both figures is the vibration waveform of the energy storage stage, and through comparison, it can be clearly obtained that when the technical solution of the present application is used, the residual vibration of the energy storage stage is well suppressed.
[0069] In addition, by referring to FIG. 17, the anisotropic vibration of the present embodiment occurs as follows.
[0070] The driving signal represents the phase state of the excitation signal input to the vibrating unit (30) to drive the movement of the vibrating member (33). Although the driving signal period of the first driving exciter (100) and the second driving exciter (200) is the same, the phase difference between the two is half a period, so the vibration directions of the two vibrating members (33) are opposite to each other. As the driving signal is continuously input, the energy possessed by the vibrating member (33) gradually increases, and in an ideal state, the composite waveform of the opposite vibrations of the two vibrating bodies (33) forms a roughly straight line. When the acceleration reaches a certain level, the driving signal is cut off, and the first driving exciter (100) and the second driving exciter (200) sequentially enter the second state. The time difference is about half a period to ensure that the first driving exciter (100) and the second driving exciter (200) can generate anisotropic vibrations in the same direction when the vibrating unit (30) comes into contact with the braking unit (40). After that, the two vibration units (30) are sequentially braked by the corresponding braking unit (40) to generate two anisotropic vibrations with a phase difference of about half a period, and if the period is sufficiently short, the two anisotropic vibrations can be detected as one distinct vibration.
[0071] The technical solution of the present application switches the driving excitation between a first state and a second state through a locking catch member (53) that is movably installed, and in the first state, the vibrating member (30) is relatively fixed; in the second state, the vibrating member (30) comes into contact with the braking member (40), and the braking member (40) brakes the vibrating member (30) to generate anisotropic vibration, and in order to generate such anisotropic vibration, cooperation between the braking member (40) and the vibrating member (30) is required, and since the frequency of vibration generation depends on the frequency with which the vibrating member (30) moves and comes into contact with the braking member (40), when the locking catch member (53) continuously moves to continuously switch between the first state and the second state, the vibrating member (30) comes into contact with the braking member (40) intermittently, thereby generating anisotropic vibration discretely.
[0072] The technical solution of the present application can significantly expand the asymmetry of anisotropic vibration and discretely display asymmetric vibration within a short period of time. In addition, by generating vibrations close to the actual asymmetric vibration force, a distinct force sensation directed toward a specific direction can be discretely displayed within a short period of time, and since the direction of this force sensation is determined by the contact direction of the braking part (40) and the vibration part (30), the gripping method is no longer limited.
[0073] In addition, the driving excitation device (1000) of the present application uses an even number of interconnected driving exciters, and the vibration members (33) of two adjacent driving exciters vibrate in opposite directions, thereby eliminating unnecessary vibrations generated during the energy storage stage, so that the generated anisotropic vibrations are made purer, thereby exhibiting force feedback with a more distinct sense of direction, suppressing noise generation to some extent, and improving the operating quality and user experience of the driving excitation device (1000).
[0074] Referring to FIG. 12, in one embodiment of the present invention, an even number of vibration members (33) are installed coaxially with the center. In one embodiment, the driving excitation device includes a first driving exciter (100) and a second driving exciter (200), and the internal structure of the first driving exciter (100) and the second driving exciter (200) is identical, and both are equipped with one vibration part (30), two braking parts (40) on both sides, and a locking catch part (50). The first driving exciter (100) and the second driving exciter (200) are connected to each other along a first direction, and the shells of the two are joined or bonded, of course, the method of connection is not limited as long as it can transmit vibration.
[0075] At the same time, the two vibration members (33) move in directions toward or toward each other, and the centers of the two vibration members (33) are located on the same straight line so that the vibrations generated by the two can be relatively thoroughly canceled out from each other, thus achieving a better suppression effect on unnecessary vibrations of the energy storage stage.
[0076] By analogy, in some other embodiments of the present application, the driving excitation device (1000) may be equipped with four, eight, or more driving exciters, and the direction of motion of the vibration members (33) of the driving exciters in pairs at the same time is opposite to each other.
[0077] In an embodiment of another aspect of the present application, when a plurality of driving exciters are installed in the driving excitation device (1000), a plurality of vibration members (33) may be installed offset from each other or partially offset from each other to obtain various vibration effects.
[0078] Referring to FIGS. 1 and FIGS. 12, in one embodiment of the present invention, the shell comprises a shell body and a support (10), wherein an even number of shell bodies are sequentially connected along a first direction, and the support (10) is installed within the space, and the support (10) comprises a mounting member (11) and a guide structure (13) connected to the mounting member (11), and the mounting member (11) is connected to at least one side of the shell body along the first direction, and a braking part (40) and a locking catch part (50) are connected to the mounting member (11), and a vibration part (30) is movably connected to the guide structure (13).
[0079] In this embodiment, the shape of the housing (31) is not limited as long as the excitation space formed thereby is sufficient to support the vibrating member (30) so that it can move a certain distance and collide with the braking member. The mounting member (11) is approximately plate-shaped, and one surface thereof is fixedly connected to the inner wall of the housing (31), and the guide structure (13) is installed on one side of the mounting member (11) and fixedly connected to the mounting member (11), and the vibrating member (30) and the guide structure (13) are movably matched and connected, and the braking member (40) is fixed to the surface of the mounting member (11) facing the vibrating member (30), and the guide structure (13) may be installed surrounding the braking member (40) or installed on one side of the braking member (40), but is not limited thereto.
[0080] Optionally, the guide structure (13) may be one or more guide rods (131) connected to the mounting member (11), and the vibrating member (30) is installed over the guide rod (131); the guide structure (13) may have a track groove installed, and the vibrating member (30) is installed slidably within the track groove. By installing the mounting member (11) and the guide structure (13) to provide structural support and guidance to the braking member (40) and the position limiting member, the internal structure of the driving exciter is made more stable and the movement of the vibrating member (30) is made smoother and faster.
[0081] Referring to FIGS. 1, 4 and 5, in one embodiment of the present invention, a vibrating member (30) comprises a housing (31), two elastic members (37) and two groups of magnetic members (36), wherein the housing (31) is connected to a guide structure (13), the housing (31) surrounds a vibrating space, and the vibrating member (33) is installed to vibrate within the vibrating space; the two elastic members (37) are installed on both sides of the vibrating member (33) along a first direction, and the elastic members (37) connect the housing (31) and the vibrating member (33); and the two groups of magnetic members (36) are fixed within the vibrating space and installed on opposite sides of the vibrating member (33) perpendicular to the first direction, and opposite magnetic poles are installed on one side of each group of magnetic members (36) facing the vibrating member (33). A coil is installed in the vibration member (33), and in the first state, the current direction of the coils of two adjacent driving exciters is opposite to each other.
[0082] In this embodiment, the housing (31) includes two end covers installed oppositely and a connecting plate installed between the two end covers, each end cover having two mounting ears installed on symmetrical or identical sides, and the mounting ears are provided with a bypass yield hole through which a guide rod (131) passes, and the mounting ears between the two end covers are installed facing each other and are connected through a shaft sleeve (311).
[0083] The vibrating member (33) vibrates along a specific direction within the vibration space, and simultaneously vibrates the elastic member (37) while the vibrating member (33) vibrates and stores the generated energy within the elastic member (37). When the housing (31) comes into contact with the braking member (40), the stored energy is released to the braking member (40) to generate a vibration wave. Since the vibrating member (30) comes into contact with the braking member (40) from one side, the generated vibration is unilateral and has clear asymmetry. That is, the sensation of being pulled toward a specific direction is actually present and does not depend on the user's gripping method or sensory experience.
[0084] Referring to FIG. 12, in this embodiment, each group of magnetic members (36) is an independent, approximately "U"-shaped permanent magnet, and the polarities of the two ends of the permanent magnets facing the vibrating member (33) are opposite to each other, and the polarities of the opposing surfaces of the two groups of permanent magnets are also opposite to each other. When power is supplied to the coil to generate a magnetic field, the vibrating member (33) moves in a specific direction due to the interaction between the magnetic poles. Since the direction of the magnetic field of the coil changes when the direction of the current changes, the direction of movement of the vibrating member (33) also changes. Therefore, it can be understood that if the current direction of the coils of the vibrating members (33) of two adjacent driving exciters is opposite to each other, the direction of movement of the vibrating member (33) is also opposite to each other.
[0085] Of course, each group of magnetic members (36) may also include two permanent magnets, and the polarity of the surfaces of the two permanent magnets toward the vibrating member (33) is opposite to each other.
[0086] In another embodiment, a coil is fixed within the vibration space, and a permanent magnet is inserted and installed in the vibration member (33). When current flows through the coil and a magnetic field is generated, the vibration member (33) vibrates due to the action of the magnetic field, and when the direction of the current changes, the direction of motion of the vibration member (33) changes.
[0087] The vibration driving method of the vibration member (33) is not limited to the above embodiment, and is no longer limited as long as it can drive the movement of the vibration member (33) and change the direction of movement regularly and periodically.
[0088] In one embodiment of the present invention, the vibration member (30) further comprises a first yoke plate (34) and a second yoke plate (35), the first yoke plate (34) and the second yoke plate (35) are installed opposite each other and fixedly connected to a housing (31), and the elastic member (37) is a spring piece, one end of the spring piece is connected to the first yoke plate (34) or the second yoke plate (35), and the other end of the spring piece is connected to the end of the vibration member (33).
[0089] Optionally, referring to FIG. 5, the cross-section of the vibration member (33) of the present embodiment is approximately a parallelogram, and if the first direction is defined as the left-right direction and the up-down direction perpendicular to the first direction on paper, the first yoke plate (34) is installed upward and the second yoke plate (35) is installed downward, the upper left end of the vibration member (33) is connected to the second yoke plate (35), and the lower right end of the vibration member (33) is connected to the first yoke plate (34).

[0090] Referring to FIG. 1, in one embodiment of the present invention, the support member (10) further includes a first connecting rack (15) installed in parallel with the guide structure (13), the first connecting rack (15) is connected to a mounting member (11), and a driving member (51) is fixed to the first connecting rack (15); a rotating shaft is installed in the driving member (51), and a locking catch member (53) is a locking rod, one end of the locking catch member (53) is connected to the rotating shaft, and the longitudinal direction of the locking catch member (53) forms an angle with the extension direction of the rotating shaft.

When the driving member (51) receives a designated signal, the rotation axis rotates the locking catch member (53) until the locking catch member (53) comes into contact with the shell of the vibrating part (30) or the locking catch member (53) moves away from the vibrating part (30). In this way, the movement of the locking catch member (53) and the transition between the first state and the second state can be implemented simply and conveniently.
[0093] In an embodiment of another aspect of the present invention, a driving member (51) drives a locking catch member (53) to move in a straight line, and the direction of movement of the locking catch member (53) forms an angle with the first direction.

Preferably, the straight line where the direction of movement of the locking catch member (53) is located and the straight line where the direction of vibration of the vibration member (33) is located are installed at a 90-degree angle, so that the structure is simple and effective, and at the same time, the generation and transmission of vibration are relatively clear, resulting in a good effect.
[0094] Of course, the driving member (51) may be in a different structural form capable of implementing the above technical concept, but is not limited thereto, and correspondingly, the structure of the locking catch member (53) may be changed according to the structural form or spatial arrangement of the driving member (51), but is not limited thereto.
[0095] Referring to FIGS. 2 and 3, in one embodiment of the present invention, the locking catch portion (50) further includes a position limiting member (55), the position limiting member (55) is connected to a first connecting rack (15), a position limiting groove (55a) is formed in the position limiting member (55), a notch (55b) facing the vibration portion (30) is formed on the side wall of the position limiting groove (55a), one end of the locking catch member (53) connected to the driving member (51) enters into the position limiting groove (55a), and one end of the locking catch member (53) moving away from the driving member (51) comes out of the notch (55b), and the locking catch member (53) rotates between two opposing side walls of the notch (55b).

The driving member (51) can drive the locking catch member (53) to rotate in the space between the two side walls of the notch (55b), and when the locking catch member (53) comes into contact with one of the side walls, the locking catch member (53) also comes into contact with the vibrating member (30); and when the locking catch member (53) comes into contact with the other side wall, the locking catch member (53) is detached from the vibrating member (30). Installing an additional position limiting member (55) limits the movement range of the locking catch member (53), is somewhat advantageous for offsetting the inertia of the locking catch member (53), and improves the operational efficiency and stability of the locking catch member (53).
[0097] In one embodiment of the present invention, the guide structure (13) includes at least two guide rods (131) extended along a first direction, and the ends of the guide rods (131) are fixed to a mounting member (11), and the vibrating member (30) further includes a housing (31), and at least two shaft sleeves (311) are installed on the side of the housing (31), and one shaft sleeve (311) is movably installed over one guide rod (131). The guide rod (131) may be installed surrounding the braking unit (40) or installed on one side of the braking unit (40), and a bearing is installed within the shaft sleeve (311). The vibrating unit (30) may move closer to or further away from the braking unit (40) along the guide rod (131), and by installing the guide rod (131) to provide structural support and guidance to the position limiting unit, the internal structure of the driving excitation device becomes more stable and the movement of the vibrating unit (30) becomes smoother and faster.
[0098] Additionally, referring to FIG. 6, in one embodiment of the present invention, the mounting member (11) includes a mounting body (111) and a cover plate (113), wherein the mounting body (111) is provided with a mounting groove and a through hole (111a) installed in the bottom wall of the mounting groove, the guide structure (13) is connected to the mounting body (111), the cover plate (113) blocks the opening of the mounting groove and is detachably connected to the mounting body (111), and the braking part (40) is fixedly connected to the cover plate (113) through the through hole (111a). The cover plate (113) is bolted to the mounting body (111), and the braking unit (40) is attached or bolted to the cover plate (113). Since the interaction between the vibration unit (30) and the braking unit (40) inevitably causes hardware loss, the cover plate (113) in this embodiment is detachable, allowing for the replacement of the braking unit (40) or maintenance of the device to be performed conveniently and quickly.
[0099] Referring to FIGS. 7 to 11, in one embodiment of the present invention, the locking catch portion (50) includes two locking catch members (53), and the two locking catch members (53) are located on both sides of the vibration portion (30) to form a position-limiting space, and a driving member (51) is connected to at least one locking catch member (53). Here, in the first state, the vibration portion (30) is position-limited within the position-limiting space. In this embodiment, the locking catch member (53) may be a block-shaped body or a rod-shaped body, and optionally, a braking portion (40) is installed on one side of the vibration member (33) along a first direction, and the two locking catch members (53) are installed at a distance to form the vibration space. That is, in this embodiment, a single braking member (40) installed on one side is installed in the driving excitation device, and the locking catch member (53) on one side is fixed and does not move, and the driving member (51) is connected to the locking catch member (53) on the other side and drives the locking catch member (53) to rotate or translate, thereby switching the driving excitation device between a first state and a second state.
[0100] The vibration unit (30) and the braking unit (40) can cooperate to generate anisotropic vibrations in one direction, and when an even number of driving exciters cooperate, the braking unit (40) can be installed in the same direction or installed in opposite directions to obtain various vibration effects.
[0101] For example, in one embodiment, the braking units (40) of an even number of driving exciters are all installed on one side of the interior, and when the driving exciters are excited sequentially, multiple vibrations in the same direction are generated; in another embodiment, some of the braking units (40) of the driving exciters are installed on one side along the first direction, and some of the braking units (40) of the driving exciters are installed on the other side, and when the driving exciters are excited sequentially, multiple vibrations in different directions are superimposed, and through calculation or control, various vibration force sensations having different durations, intensities, and levels in an ideal state can be discretely generated.
[0102] Referring to FIGS. 1 and FIGS. 12, in another embodiment of the present invention, each driving exciter comprises two braking units (40) and two locking catch units (50), the two braking units (40) are fixed to opposite sides of the vibrating unit (30) along a first direction, each locking catch unit (50) comprises one driving member (51) and one locking catch member (53), the two locking catch members (53) are each installed on both sides of the vibrating unit (30) along the first direction, and each locking catch member (53) is installed between the vibrating unit (30) and the braking unit (40) to form a position limiting space; wherein, in the first state, the vibrating unit (30) is positionally limited within the position limiting space.
[0103] In this embodiment, at least one second connecting rack (17) is installed between two mounting members (11), and both ends of the second connecting rack (17) are each connected to the mounting members (11) to further ensure structural stability. A locking catch member (53) is installed on one side of a driving member (51) along a first direction, and when observing the driving excitation along the first direction, two locking catch members (53) may be installed together on one side of the vibration unit (30) or may be installed symmetrically on two opposing sides of the vibration unit (30), and both locking catch members (53) may move, but in the second state, only one of the locking catch members (53) moves and detaches from the vibration unit (30). For example, if the first direction is defined as the left-right direction, when the right locking catch member (53) moves, the left locking catch member (53) remains fixed and does not move, so the vibration unit (30) moves to the right; When the left locking catch member (53) moves, the right locking catch member (53) remains fixed and does not move, so the vibrating member (30) moves to the left, that is, in the second state, the vibrating member (30) approaches only one of the braking members (40), and the anisotropic vibrations generated by the vibrating member (30) in cooperation with each of the two braking members (40) are opposite to each other.
[0104] That is, in this embodiment, the driving exciter can implement the vibration part (30) moving in different directions, thereby exhibiting opposite anisotropic vibrations in two directions, but it should be noted that these two vibrations do not exist simultaneously. When an even number of driving exciters cooperate, various vibration effects can be obtained by controlling the even number of driving exciters on the same side to open sequentially or by controlling the locking catch members (53) on different sides to open sequentially in an alternating manner.

[0106] Referring to FIG. 1, in one embodiment of the present invention, the driving exciter further includes a return member (60), and the return member (60) is a spring, or both ends of the spring are elastically connected to the vibrating part (30) and the shell. By installing the return member (60), the vibrating part (30) can be smoothly returned after the braking step to restore the driving exciter to a first state. Of course, the return member (60) is not limited to a spring and may be another structure capable of returning the vibrating part (30).
[0107] Optionally, to protect the hardware and achieve good vibration transmission, a cushioning member (39) facing the braking member (40) is installed at the end of the vibrating member (30) along the first direction, and the cushioning member (39) can be made of an elastic material such as rubber.
[0108] Optionally, in one embodiment of the present invention, the braking member (40) is a spring; or, the braking member (40) is rubber; or, the braking member (40) is foam; or, the braking member (40) is configured by installing at least two of the spring, rubber, and foam in series or in parallel, that is, two or three of the spring, rubber, and foam are installed sequentially in a symmetrical manner to obtain a good braking effect, or are installed side by side to brake the vibration member (30) to ensure structural stability.
