[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0045] The airflow regulator 2 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The airflow regulator 2 can be used to form a wind field or to regulate a wind field.
[0046] According to a first aspect of the present invention, an airflow regulating member 2 includes a vibrating plate 22 and a driver 21, wherein the driver 21 is disposed on the vibrating plate 22 and is used to drive the vibrating plate 22 to reciprocate.
[0047] When the airflow regulator 2 is used to form a wind field, the driver 21 drives the vibrating plate 22 to vibrate back and forth, which can induce airflow and form an airflow path, thereby forming a wind field. It can replace the impeller to achieve the function of air delivery. When the airflow regulator 2 is used to adjust the wind field, the airflow regulator 2 can be used in conjunction with the impeller 50. The impeller 50 acts as an air delivery component. When it is necessary to adjust the wind field formed by the impeller 50, the airflow regulator 2 can be turned on, so that the driver 21 works to drive the vibrating plate 22 to vibrate back and forth to turbulent the airflow. This turbulence can adjust the wind field formed by the impeller 50. For example, the wind direction, wind speed, and wind feel of the wind field formed by the impeller 50 can be adjusted to make the airflow more diverse and meet more user needs.
[0048] The device comprises one vibrating plate 22 and multiple drivers 21, each driver 21 connected to the vibrating plate 22 to drive the vibrating plate 22 to reciprocate. At least two of the drivers 21 are independently controlled. Each driver 21 can be used to drive the vibrating plate 22 to reciprocate. Since at least two of the drivers 21 are independently controlled, all drivers 21 can be operated, or only some of the drivers 21 can be operated.
[0049] It should be noted that, in this invention, "multiple" refers to two or more.
[0050] For a single airflow regulator 2, the mass of the vibrating plate 22 remains constant, and the natural frequency of the vibrating plate 22 itself remains constant. The sum of the masses of all non-operating actuators 21 and the vibrating plate 22 is greater than the mass of the vibrating plate 22. Considering all non-operating actuators 21 and the vibrating plate 22 as a whole, and considering the whole formed by all non-operating actuators 21 and the vibrating plate 22 as a single vibration unit, the mass of the vibration unit can vary depending on the number of non-operating actuators 21. When all actuators 21 are operating, the vibrating plate 22 itself can function as a vibration unit. Thus, by controlling all actuators 21, the mass of the vibration unit can be changed, thereby changing the natural frequency of the vibration unit. This allows for frequency adjustment of the vibration unit, enabling the airflow regulator 2 to switch between multiple different vibration frequencies and meet more airflow requirements.
[0051] Optionally, the mass of each driver 21 can be the same, so that the mass of the above-mentioned vibration unit can be changed by controlling the number of non-operating drivers 21, thereby conveniently adjusting the natural frequency of the vibration unit.
[0052] Optionally, while ensuring that each driver 21 has the same mass, the material, size and shape of each driver 21 are also the same, thereby reducing the variety of drivers 21, so that each driver 21 can use the same type of driver 21 and the same specification of driver 21.
[0053] Optionally, the mass of each driver 21 can also be different. In this way, when only one driver 21 is working, the mass of the above-mentioned vibration unit will be different when drivers 21 of different masses are working. This not only allows the mass of the above-mentioned vibration unit to be changed by controlling the number of drivers 21 that are not working, thereby conveniently adjusting the natural frequency of the vibration unit; but also allows the natural frequency of the vibration unit to be conveniently adjusted when only one driver 21 is working, if drivers 21 of different masses are working, the natural frequency of the vibration unit will be different. This makes the natural frequency of the vibration unit adjustable to a wider range of values, resulting in more diverse airflow.
[0054] The vibration frequency primarily affects the wind speed. Generally, a higher vibration frequency results in a higher wind speed, and vice versa. When the airflow regulating component 2 is used to create a wind field, the wind speed can be adjusted by regulating the vibration frequency of the aforementioned vibration unit to meet various airflow requirements. When the airflow regulating component 2 is used to regulate the wind field, the vibration frequency of the aforementioned vibration unit can be adjusted to create different disturbances to the wind field, thereby regulating the wind speed, wind feel, etc., to diversify the airflow and meet more user needs.
[0055] According to an embodiment of the present invention, the airflow regulating component 2 is provided with a vibrating plate 22 and a plurality of drivers 21, and each driver 21 is connected to the vibrating plate 22 to drive the vibrating plate 22 to reciprocate. At the same time, at least two of the drivers 21 are independently controlled, which can realize the change of the vibration frequency of the airflow regulating component 2, realize the switching between multiple different frequencies, and meet more air outlet requirements.
[0056] According to some embodiments of the present invention, the working driver 21 is adapted to drive the vibrating plate 22 and the non-working driver 21 to resonate, that is, the working driver 21 can drive the aforementioned vibration unit to resonate. For example, when all drivers 21 are working, the vibrating plate 22 serves as the vibration unit, and all drivers 21 are used to drive this vibration unit to resonate; as another example, when some drivers 21 are working and others are not working, the non-working driver 21 and the vibrating plate 22 constitute the vibration unit, and the working driver 21 is used to drive this vibration unit to resonate. Thus, the vibration amplitude of the vibrating plate 22 can be made larger, thereby increasing the airflow regulation effect of a single airflow regulator 2. When the airflow regulator 2 is used to form a wind field, the induced air volume and the supplied air volume of a single airflow regulator 2 can be increased, which can simply and effectively meet the air supply requirements; when the airflow regulator 2 is used to regulate the wind field, the regulating force of a single airflow regulator 2 on the wind field can be increased, achieving the expected regulating effect.
[0057] Understandably, "resonance," also known as "resonance," occurs when the frequency of the driving force equals the system's natural frequency, resulting in the maximum amplitude of forced vibration. This phenomenon is called resonance. In an oscillating system under periodic external forces, when the frequency of the external force is the same as or very close to the system's natural oscillation frequency, the amplitude increases dramatically. The frequency at which resonance occurs is called the "resonant frequency." Furthermore, "natural frequency," also called "natural frequency," refers to the frequency of free vibration. When an object vibrates freely, its displacement changes with time according to a sine or cosine law. The frequency of vibration is independent of initial conditions and depends only on the system's inherent characteristics (such as mass, shape, and material). This is called the natural frequency, and its corresponding period is called the natural period. The natural frequency is unrelated to external excitation; it is an inherent property of the structure. Regardless of whether external excitation is applied to the structure, its natural frequency exists. However, when external excitation occurs, the structure vibrates according to its natural frequency. In addition, "free vibration" refers to the vibration that occurs in a mechanical system after the excitation or constraint is removed. The vibration is maintained only by its elastic restoring force. When damping is applied, the vibration gradually decays. The frequency of free vibration is determined only by the physical properties of the system itself and is called the natural frequency of the system.
[0058] In simple terms, when the excitation frequency of the driver 21 is the same as or close to the natural frequency of the aforementioned vibration unit, the resonance effect is utilized, and the vibration generated by the vibration unit is called resonance. The amplitude of the vibration unit will increase sharply, thereby enabling the vibration unit to effectively regulate the airflow and generate a wind-blowing effect that induces airflow to form a wind field or effectively regulate the wind field. Otherwise, it is ordinary vibration.
[0059] Since at least two of the actuators 21 in the airflow regulator 2 of the present invention can be independently controlled, the vibration unit of the airflow regulator 2 can be changed as needed, thereby changing the natural frequency of the vibration unit. This allows the airflow regulator 2 to have multiple airflow regulation modes with different resonant frequencies, enabling it to switch to different airflow regulation modes as needed. In different airflow regulation modes, the natural frequency of the vibration unit of the airflow regulator 2 is different, resulting in different resonant frequencies for the airflow regulator 2. Therefore, the intensity of the regulated airflow can be changed in different airflow regulation modes.
[0060] For example, in the airflow regulation mode with a higher resonant frequency, the airflow regulator 2 has a stronger airflow regulation effect. When used to form a wind field, it can result in a higher wind speed; when used to regulate the wind field, it can achieve a greater degree of wind field regulation. In the airflow regulation mode with a lower resonant frequency, the airflow regulator 2 has a weaker airflow regulation effect. When used to form a wind field, it can result in a lower wind speed; when used to regulate the wind field, it can achieve a smaller degree of wind field regulation. By enabling the airflow regulator 2 to have multiple airflow regulation modes with different resonant frequencies, it can be switched to different airflow regulation modes as needed to form different wind fields or to regulate the wind field differently, thereby meeting more diverse air supply requirements.
[0061] Optionally, the number of non-operating actuators 21 can be different in different airflow regulation modes. By controlling the number of non-operating actuators 21, the mass of the vibration unit can be changed, thereby conveniently achieving the adjustment of the vibration unit's natural frequency. For example, the mass of each actuator 21 can be the same. Thus, by controlling the number of non-operating actuators 21, the mass of the vibration unit can be changed, thereby conveniently achieving the adjustment of the vibration unit's natural frequency.
[0062] According to some embodiments of the present invention, the actuator 21 may include at least one of the following: inverted piezoelectric actuator, electrostrictive actuator, magnetostrictive actuator, shape memory alloy actuator, mechanical actuator, servo actuator, and electrorheological fluid actuator.
[0063] For example, the actuator 21 can be an inverse piezoelectric actuator, employing the inverse piezoelectric effect. Specifically, the actuator 21 can be a piezoelectric sheet, such as a piezoelectric ceramic sheet. The inverse piezoelectric effect of the sheet causes it to reciprocate, driving the aforementioned vibration unit to resonate, thereby forming or regulating a wind field. Alternating current can be used to drive the piezoelectric sheet to produce the inverse piezoelectric effect, thus driving the aforementioned vibration unit to resonate.
[0064] For example, when the actuator 21 is a piezoelectric element, an alternating voltage is applied in the polarization direction of the piezoelectric element, causing the piezoelectric element to undergo periodic mechanical deformation in a certain direction. Resonance (or synchrotron resonance) occurs only when the excitation frequency of the piezoelectric element (the excitation frequency of the piezoelectric element is the frequency of the alternating voltage applied to the piezoelectric element) is equal to or close to the natural frequency of the aforementioned vibration unit. At this time, the amplitude of the vibration unit will increase sharply, thereby enabling the vibration unit to more effectively regulate the airflow, thus forming or regulating a wind field.
[0065] Optionally, the voltage amplitude of the alternating voltage applied to the driver 21 is adjustable. When the vibration unit of the airflow regulator 2 resonates, the amplitude of the vibration unit can be further adjusted by changing the voltage amplitude of the alternating voltage applied to the operating driver 21, thereby further realizing the formation of different wind fields or different adjustments to the wind fields, resulting in more diversified airflow and more precise control over the airflow.
[0066] For example, the actuator 21 can be an electrostrictive actuator, which drives the aforementioned vibration unit to resonate through the electrostrictive effect. Specifically, the electrostrictive effect refers to the phenomenon of elastic deformation of a dielectric in an electric field. This phenomenon can be explained as follows: when a dielectric is placed in an electric field, its molecules become polarized, with the positive pole of one molecule connecting to the negative pole of another molecule along the direction of the electric field. Due to the mutual attraction between the positive and negative poles, the entire dielectric contracts in this direction until the elastic force and electro-attraction within it are balanced. In short, the electrostrictive actuator can be deformed by alternating current, thereby causing the vibration unit to resonate.
[0067] Furthermore, it should be noted that the difference between electrostriction and the inverse piezoelectric effect lies in the following: the inverse piezoelectric effect is a linear response effect with a first-order term, and can only occur in solid dielectrics without a center of symmetry. The piezoelectric constant is a third-order tensor; the physical property parameters describing the electrostriction effect in anisotropic dielectrics are fourth-order tensors. In non-piezoelectric dielectrics, only the electrostriction effect occurs; in piezoelectric materials, both the piezoelectric and electrostriction effects occur simultaneously. Generally, the strain caused by the electrostriction effect is several orders of magnitude smaller than that caused by the inverse piezoelectric effect in piezoelectric materials.
[0068] For example, the actuator 21 can also be a magnetostrictive actuator, driving the vibrating unit to resonate through the magnetostrictive effect. Specifically, the magnetostrictive effect refers to the phenomenon where an object, when magnetized in a magnetic field, elongates or shortens in the direction of magnetization. Ferromagnetic materials, whose dimensions change significantly when the current through the coil changes or the distance from the magnet changes, are commonly called ferromagnetic materials. Their dimensional changes are much larger than those of current magnetostrictive materials such as ferrites, and they also generate more energy; therefore, they are called supermagnetic materials. Because the length of a magnetostrictive material changes under the influence of a magnetic field, it can undergo displacement and do work, or it can repeatedly stretch and shorten under the influence of an alternating magnetic field, thus generating vibration. This material can convert electromagnetic energy (or electromagnetic information) into mechanical energy. In short, the magnetostrictive actuator is deformed by an alternating magnetic field, thereby causing the vibrating unit to resonate.
[0069] For example, the actuator 21 can be a shape memory alloy actuator, driving the vibration unit to resonate through the deformation of the shape memory alloy. Specifically, shape memory alloys (SMA) undergo a martensitic phase transformation under external fields (temperature, stress, magnetic fields, etc.), exhibiting shape memory and superelasticity, outputting force and displacement. They are advanced intelligent materials integrating temperature sensing and intelligent actuation, possessing unique shape memory effects and phase transformation pseudoelasticity, and are widely used in aerospace, medical devices, and mechanical and electrical fields. Shape memory alloys have three characteristics: large deformation; large degree of freedom in displacement direction; and rapid displacement. Therefore, they feature large displacement, high power-to-weight ratio, rapid displacement, and directional freedom. They are particularly suitable for low-load, high-speed, high-precision robotic assembly operations, sample movement devices within microscopes, reactor drive devices, medical endoscopes, artificial hearts, detectors, and protectors. In short, the temperature of the shape memory alloy actuator is changed by heating or cooling, and the deformation of the shape memory alloy actuator is driven by the change in temperature field, thereby causing the vibration unit to resonate.
[0070] For example, the actuator 21 can be an electrorheological fluid actuator, which drives the vibration unit to resonate by deforming the electrorheological fluid. Specifically, an electrorheological fluid (ERF) is a smart material whose viscosity changes with the strength of the applied electric field. Without an electric field, the ERF flows freely like a normal liquid, essentially a Newtonian fluid. When the applied electric field strength reaches a certain value, the properties of the ERF change significantly: the viscosity increases and gradually loses fluidity, shear resistance increases, and it rapidly transforms from a liquid to a near-solid state. After the electric field is removed, it quickly returns to a liquid state. This state change can be achieved in just milliseconds, and this transformation is completely reversible. In short, the alternating electric field drives the electrorheological fluid actuator to deform, thereby causing the vibration unit to resonate.
[0071] For example, the driver 21 can be a servo actuator, which can be a hydraulic actuator that converts hydraulic energy from a hydraulic source into mechanical energy. It can also be servo controlled via a built-in displacement sensor or limit switch as needed. It executes commands from the main controller to control the load's speed, direction, displacement, and force, while simultaneously feeding back signals to the main controller. It features high output force, accurate positioning, and small size. In short, the servo actuator drives the vibration unit to resonate.
[0072] For example, the driver 21 can also be a mechanical actuator, which can be driven directly by a high-speed motor or driven by a mechanical mechanism to cause the vibration unit to resonate, etc., which will not be elaborated here.
[0073] According to some embodiments of the present invention, each actuator 21 is independently controlled. With the same number of actuators 21, by making each actuator 21 independently controlled, the airflow regulator 2 can have more different vibration frequencies, resulting in more diverse airflow regulation modes and meeting more diverse air supply needs.
[0074] In some optional embodiments of the present invention, the actuator 21 is a piezoelectric element, and each actuator 21 is independently controlled. The mass of each actuator 21 can be the same or different. For example, when the mass of each actuator 21 is the same, the mass of the vibration unit (the mass of the vibration unit is the sum of the mass of the vibrating plate 22 and the mass of all non-operating actuators 21) can be controlled by controlling the number of non-operating actuators 21. Different numbers of non-operating actuators result in different masses of the vibration unit, thereby causing different natural frequencies of the vibration unit, and thus enabling the airflow regulating unit to have multiple airflow regulating modes with different resonant frequencies.
[0075] For example, when the mass of each actuator 21 is different, the mass of the vibration unit (the mass of the vibration unit is the sum of the mass of the vibrating plate 22 and the mass of all non-operating actuators 21) can be controlled not only by controlling the number of non-operating actuators 21, but also by the number of non-operating actuators 21, resulting in different masses of the vibration units (achieved by setting the mass of the actuators 21). This leads to different natural frequencies of the vibration units, allowing the airflow regulating unit to have multiple airflow regulating modes with different resonant frequencies. Furthermore, when only one actuator 21 is operating, since the mass of each actuator 21 is different, the mass of the vibration unit is also different when actuators 21 of different masses are operating, resulting in different natural frequencies of the vibration units. This allows the airflow regulating unit to have even more airflow regulating modes with different resonant frequencies. When the number of actuators 21 is the same, the airflow regulating mode of the airflow regulating component 2 can be more diversified, better meeting more diverse airflow requirements.
[0076] According to some embodiments of the present invention, with reference to Figures 1-8 All the actuators 21 are arranged sequentially in the direction from the root 221 of the vibrating plate 22 to the tip 222 of the vibrating plate 22. By arranging all the actuators 21 in the direction from the root 221 of the vibrating plate 22 to the tip 222 of the vibrating plate 22, the structure of the airflow regulator 2 can be made simple and easy to manufacture.
[0077] According to some optional embodiments of the present invention, refer to Figures 1-8In the direction from the root 221 to the tip 222 of the vibrating plate 22, all the drivers 21 are arranged in sequence, and the root 221 of the vibrating plate 22 is provided with a driver 21. Here, the root 221 of the vibrating plate 22 refers to the end of the vibrating plate 22 that is fixed, and the tip 222 of the vibrating plate 22 refers to the free end of the vibrating plate 22. The vibrating plate 22 can be elongated, and the two ends in the length direction of the vibrating plate 22 can be the root 221 and the tip 222, respectively. The root 221 can be fixed. When the vibrating plate 22 vibrates, the tip 222 is located downstream of the root 221, and the airflow generally flows in the direction from the root 221 to the tip 222 of the vibrating plate 22. All the actuators 21 of the airflow regulator 2 are arranged sequentially from the root 221 of the vibrating plate 22 towards the tip 222 of the vibrating plate 22. When a voltage is applied to the actuators 21, the tip 222 of the vibrating plate 22 can undergo a large vibration displacement, which reduces the energy consumption of the airflow regulator 2 during operation. Furthermore, the airflow regulation effect of the aforementioned vibration unit is easy to control, thereby making it easier to control the wind field formed or the wind field regulation during the operation of the airflow regulator 2, and making it easier to achieve the expected requirements for the wind field formed or the wind field regulation during the operation of the airflow regulator 2.
[0078] Optionally, the distance d between two adjacent drivers 21 is no greater than 10 mm, that is, the distance d between two adjacent drivers 21 ranges from 0 to 10 mm. Two adjacent drivers 21 can be in contact, in which case the distance d between them is 0 (e.g., refer to...). Figures 1-3 as well as Figures 5-7 A gap may also exist between two adjacent drivers 21, in which case the distance d between two adjacent drivers 21 is greater than 0 and not greater than 10mm (for example, refer to...). Figure 4 as well as Figure 8 By ensuring that the distance d between two adjacent actuators 21 is no greater than 10mm, the overall length of the airflow regulator 2 can be reduced, thereby decreasing the space occupied by the airflow regulator 2.
[0079] Optionally, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6Along the direction from the root 221 of the vibrating plate 22 to the tip 222 of the vibrating plate 22, the length of the vibrating plate 22 exposed outside the driver 21 is L1, and the overall length of the airflow regulating component 2 is L2. The value of L1 can range from 5mm to 300mm, the value of L2 can range from 20mm to 400mm, and the value of L1 / L2 can range from 0.5 to 0.9. Therefore, while ensuring a suitable airflow, airflow adjustment is convenient, and a good airflow effect can be achieved. The length L1 of the vibrating plate 22 exposed outside the driver 21 refers to the distance between the driver 21 closest to the tip 222 and the end face of the tip 222 of the vibrating plate 22.
[0080] Optionally, when the actuator 21 is a piezoelectric element, the actuator 21 can be located on one side of the vibrating plate 22 in the thickness direction, or the actuator 21 can be located on both sides of the vibrating plate 22 in the thickness direction. The actuator 21 and the vibrating plate 22 can be stacked along the thickness direction of the vibrating plate 22. (Refer to...) Figures 1-8 When the driver 21 is located on both sides of the thickness direction of the vibrating plate 22, each driver 21 may include two sub-drivers 210 (i.e. each piezoelectric plate includes two sub-piezoelectric plates). The two sub-drivers 210 of each driver 21 are located on both sides of the thickness direction of the vibrating plate 22, and the two sub-drivers 210 of each driver 21 are arranged opposite to each other along the thickness direction of the vibrating plate 22. The two sub-drivers 210 of each driver 21 may be the same.
[0081] According to some optional embodiments of the present invention, all actuators 21 are arranged sequentially in the direction from the root 221 to the tip 222 of the vibrating plate 22, and each actuator 21 is independently controlled. There are N actuators 21, and in the direction from the root 221 to the tip 222 of the vibrating plate 22, the N actuators 21 are sequentially designated as the first to the Nth actuators 21. The first actuator 211 can be located at the root 221 of the vibrating plate 22, and the distance between the Nth actuator 21 and the end face of the tip 222 of the vibrating plate 22 is L1 as described above. The airflow regulator 2 has N airflow regulation modes, each with a different resonant frequency. These N airflow regulation modes are the first to the Nth airflow regulation modes. In the Mth airflow regulation mode, all of the first to the Mth actuators 21 are operational, and the remaining actuators 21 are inactive. Here, N ≥ 2 and is an integer, and 1 ≤ M ≤ N and is an integer. All drivers 21 are arranged in sequence in the direction from the root 221 of the vibrating plate 22 to the tip 222 of the vibrating plate 22. Each driver 21 is controlled independently. When controlling all drivers 21, the driver 21 closest to the root 221 of the vibrating plate 22 is made to work, so that the vibration of the above-mentioned vibration unit is easy to control, and the expected resonant frequency and airflow regulation effect are easily obtained.
[0082] For example, in Figures 1-4In the example, there are two actuators 21, arranged sequentially from the root 221 to the tip 222 of the vibrating plate 22, and the two actuators 21 can contact each other (e.g., refer to...). Figures 1-3 There may also be a gap between the two drivers 21 (e.g., refer to...). Figure 4 Each actuator 21 is independently controlled. In the direction from the root 221 to the tip 222 of the vibrating plate 22, the two actuators 21 are a first actuator 211 and a second actuator 212, respectively, with the first actuator 211 located at the root 221 of the vibrating plate 22. This airflow regulator 2 has two airflow regulation modes with different resonant frequencies, namely a first airflow regulation mode and a second airflow regulation mode.
[0083] In the first airflow regulation mode, the first driver 211 is operational while the second driver 212 is inactive. In this mode, the second driver 212 and the vibrating plate 22 constitute the aforementioned vibration unit. In the second airflow regulation mode, both the first driver 211 and the second driver 212 are operational, and the vibrating plate 22 constitutes the aforementioned vibration unit. The mass of the vibration unit in the first airflow regulation mode is greater than the mass of the vibration unit in the second airflow regulation mode, and the natural frequency of the vibration unit in the first airflow regulation mode is less than the natural frequency of the vibration unit in the second airflow regulation mode.
[0084] In the first airflow regulation mode, the excitation frequency of the first driver 211 can be the same as or close to the natural frequency of the vibration unit to achieve resonance; in the second airflow regulation mode, the excitation frequencies of both the first driver 211 and the second driver 212 can be the same as or close to the natural frequency of the vibration unit to achieve resonance. Since the natural frequencies of the vibration unit are different in the first and second airflow regulation modes, the resonant frequencies are different in both modes; and since the natural frequency of the vibration unit in the first airflow regulation mode is lower than the natural frequency of the vibration unit in the second airflow regulation mode, the resonant frequency of the first airflow regulation mode is lower than the resonant frequency of the second airflow regulation mode.
[0085] For example, in Figures 5-8 In the example, there are three actuators 21, which are arranged sequentially in the direction from the root 221 of the vibrating plate 22 to the tip 222 of the vibrating plate 22, and adjacent actuators 21 can contact each other (e.g., refer to...). Figures 5-7 There may also be a gap between two adjacent drivers 21 (e.g., refer to...). Figure 8Each actuator 21 is independently controlled. Along the direction from the root 221 to the tip 222 of the vibrating plate 22, the three actuators 21 are designated as a first actuator 211, a second actuator 212, and a third actuator 213, with the first actuator 211 located at the root 221 of the vibrating plate 22. This airflow regulator 2 has three airflow regulation modes, each with a different resonant frequency: a first airflow regulation mode, a second airflow regulation mode, and a third airflow regulation mode.
[0086] In the first airflow regulation mode, the first driver 211 is operational while the second driver 212 and the third driver 213 are not operational. In this mode, the second driver 212, the third driver 213, and the vibrating plate 22 constitute the aforementioned vibration unit. In the second airflow regulation mode, both the first driver 211 and the second driver 212 are operational while the third driver 213 is not operational. In this mode, the third driver 213 and the vibrating plate 22 constitute the aforementioned vibration unit. In the third airflow regulation mode, all three drivers are operational, and the vibrating plate 22 constitutes the aforementioned vibration unit. The mass of the vibration unit in the first airflow regulation mode is greater than the mass of the vibration unit in the second airflow regulation mode, and the mass of the vibration unit in the second airflow regulation mode is greater than the mass of the vibration unit in the third airflow regulation mode. The natural frequency of the vibration unit in the first airflow regulation mode is less than the natural frequency of the vibration unit in the second airflow regulation mode, and the natural frequency of the vibration unit in the second airflow regulation mode is less than the natural frequency of the vibration unit in the third airflow regulation mode.
[0087] In the first airflow adjustment mode, the excitation frequency of the first driver 211 can be the same as or close to the natural frequency of the vibration unit to achieve resonance; in the second airflow adjustment mode, the excitation frequencies of the first driver 211 and the second driver 212 can be the same as or close to the natural frequency of the vibration unit to achieve resonance; in the third airflow adjustment mode, the excitation frequencies of the first driver 211, the second driver 212 and the third driver 213 can be the same as or close to the natural frequency of the vibration unit to achieve resonance.
[0088] Since the natural frequencies of the vibration units in the first, second, and third airflow adjustment modes are all different, the resonant frequencies in the first, second, and third airflow adjustment modes are also different. Furthermore, since the natural frequency of the vibration unit in the first airflow adjustment mode is lower than the natural frequency of the vibration unit in the second airflow adjustment mode, and the natural frequency of the vibration unit in the second airflow adjustment mode is lower than the natural frequency of the vibration unit in the third airflow adjustment mode, the resonant frequency of the first airflow adjustment mode is lower than the resonant frequency of the second airflow adjustment mode, and the resonant frequency of the second airflow adjustment mode is lower than the resonant frequency of the third airflow adjustment mode.
[0089] Additionally, the alternating voltage applied to the driver 21 can be adjusted accordingly to change the amplitude, depending on the requirements. When the airflow regulator 2 is used for air outlet, different airflow regulation modes can produce different wind speeds. When the amplitudes are similar, the higher the resonant frequency, the higher the wind speed.

[0094] According to some embodiments of the present invention, with reference to Figure 9There are multiple airflow regulators 2. These airflow regulators 2 can be arranged in rows, for example, along the left and right directions; they can also be arranged in columns, for example, along the top and bottom directions; or they can be arranged in multiple rows and columns, for example, in both the top and bottom and left and right directions; or they can be arranged irregularly. By setting multiple airflow regulators 2, the air volume can be increased or the regulation effect on the air field can be enhanced to meet the air outlet requirements.

The fixing bracket 3 of the airflow regulating component 20 may have a ventilation structure through which airflow can pass. When the airflow regulating element 2 of the airflow regulating component 20 is in operation, the vibration unit of the airflow regulating element 2 reciprocates to induce airflow from the air inlet area 11 to the air outlet area 12, forming an airflow path and thus creating an airflow field to deliver air. Furthermore, the wind speed can be adjusted by controlling the operation of the driver 21 of the airflow regulating element 2.

Furthermore, the effect of regulating the wind field can be adjusted by controlling the operation of the driver 21 of the airflow regulator 2.
