Detailed Embodiments

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise stated, the meaning of "a plurality" is two or more.

[0047] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] As described in the background art, in the current sound absorption environment, the sound absorption effect and air quality are not very good. Therefore, this embodiment provides a method for manufacturing a sound absorption component for negative oxygen ion generation, a sound absorption component, and an application that can be customized for the sound absorption environment.

[0049] The following will Figures 1 to 3 make a further specific description of the method for manufacturing a sound absorption component for negative oxygen ion generation, the sound absorption component, and the application.

[0050] As Figure 1 shown, this embodiment provides a method for manufacturing a sound absorption component for negative oxygen ion generation, which is used to customize the manufacture of a sound absorption component with both sound absorption and air purification functions.

[0051] As Figure 2 shown, the sound absorption component 100 includes a telescopic frame 10 and a tourmaline sound absorption board 20. The telescopic frame 10 is installed on the target wall, the tourmaline sound absorption board 20 is installed on the telescopic frame 10, and the distance δL between the tourmaline sound absorption board 20 and the target wall is adjustable. The manufacturing method includes:

[0052] S1. Determine the target tourmaline sound absorption board according to the target noise frequency.

[0053] Among them, the target noise frequency is a specific noise frequency band to be sound-absorbed.

[0054] The target tourmaline sound-absorbing board is a PET sound-absorbing board with tourmaline fiber as one of the raw materials, and the content of tourmaline fiber is 30-40%. Tourmaline is a (polycrystalline, single-crystalline, fibrous) silicate mineral with a cyclic structure of aluminum, sodium, iron, and lithium characterized by boron content. In actual production, it usually uses tourmaline blocks, tourmaline sand, and tourmaline powder as raw materials. In this embodiment, tourmaline sand is preferably used. Tourmaline will generate a polarization voltage when heated or pressed. The polarization voltage will ionize oxygen molecules and water molecules in the air to generate negative oxygen ions, and at the same time, it can also release a weak current and far-infrared rays.

[0055] Negative oxygen ions have the effect of purifying the air and are known as "air vitamins". The effects of low negative oxygen ion concentration are: eliminating the irritation of positive charges to the human body (such as the trachea and bronchus), improving and preventing respiratory diseases, purifying the blood and improving respiratory function, relieving tension, improving sleep, regulating endocrine, eliminating free radicals in the body, reducing blood viscosity, antioxidant, anti-aging, promoting metabolism, and can also purify dust and reduce the harm of second-hand smoke.

[0056] As a preference, the target tourmaline sound-absorbing board includes the following raw materials by weight percentage: polyester fiber and / or polyamide fiber 10%-20%; low-melting-point polyester fiber 40%-55%; tourmaline fiber 30-40%, and the tourmaline fiber therein is obtained by mixing and drawing tourmaline and polyester fiber masterbatch with a weight ratio of 2-3:40-50.

[0057] The above-mentioned target tourmaline sound-absorbing board is prepared in advance, and the preparation process includes processes such as mixing, opening, carding, web laying, needling, hot pressing, and cold pressing.

[0058] Specifically, step S1 includes:

[0059] S11. Take the target noise frequency as the first resonance frequency of the target tourmaline sound-absorbing board.

[0060] It should be noted that when sound waves with a certain frequency act on the surface of the tourmaline sound-absorbing board, the surface of the board will generate certain vibrations. When sound waves with the same resonance frequency as the tourmaline sound-absorbing board act on the tourmaline sound-absorbing board, the tourmaline sound-absorbing board reaches the resonance state. When the tourmaline sound-absorbing board is in the resonance state, the sound-absorbing effect is the best. Since the amplitude of the surface of the tourmaline sound-absorbing board is relatively large in the resonance state, the vibration of the particles inside the board is relatively large, and the tourmaline material is pressed to generate a polarization voltage, and the polarization voltage ionizes oxygen molecules and water molecules in the air to generate negative oxygen ions. Therefore, in the resonance state, the amount of generated negative oxygen ions is the largest.

[0061] S12. Determine the material of the target tourmaline sound-absorbing board and determine the corresponding Young's modulus, density, and Poisson's ratio.

[0062] When the material of the tourmaline sound-absorbing board is determined, its corresponding Young's modulus, density and Poisson's ratio are all determined values.

[0063] S13. Determine the geometric dimensions of the target tourmaline sound-absorbing board according to the first resonance frequency, Young's modulus, density, and Poisson's ratio.

[0064] When the target tourmaline sound-absorbing board is a circle, a polygon, or any regular or irregular shape. Exemplarily, when the target tourmaline sound-absorbing board is a circle, the geometric dimensions include the thickness and diameter of the tourmaline sound-absorbing board. The thickness and diameter of the target tourmaline sound-absorbing board are determined according to the following formula (1):

[0065]

[0066] Where h is the plate thickness, a is the plate diameter, Emax is the plate Young's modulus, ρ is the plate density, and σ is the plate Poisson's ratio. n is the root value of the column function. According to the graphical method, μ 1 =3.2, μ 2 =6.3,μ 3 =9.44... Thus, the frequencies of vibrations from the first order to the higher order can be obtained. Usually, the first order vibration has the largest amplitude and the lowest frequency, so n=1 in formula (1).

[0067] For example, the parameters of existing tourmaline sound-absorbing panels are: E = 0.4 GPa, ρ = 200 kg / m 3 , σ=0.35, when the first resonance frequency is 639 Hz, a circular target tourmaline sound-absorbing panel is made with h=9 mm, a=100 mm as geometric dimensions, and its first-order symmetric mode resonance frequency is measured to be about 630 Hz.

[0068] For another example, when the target tourmaline sound-absorbing board is a square, the geometric dimensions include the board thickness and side length of the tourmaline sound-absorbing board. The board thickness and side length of the target tourmaline sound-absorbing board are determined according to the following formula (2):

[0069]

[0070] Where h is the plate thickness, L is the side length of the plate, E is the Young's modulus of the plate, ρ is the density of the plate, and σ is the Poisson's ratio. n To solve the root value of the equation cosh(x)*cos(x)=1, we can get μ by the graphical method: 1 =4.73,μ 2 =7.853, μ 3 =10.995... Thus, the frequencies of vibrations from the first order to the higher order can be obtained. Similarly, n=1.

[0071] Exemplarily, the parameters of the existing tourmaline sound-absorbing board are: E = 0.4 GPa, ρ = 200 kg / m 3 , σ = 0.35. When the first resonance frequency is 548 Hz, a rectangular target tourmaline sound-absorbing board is made with geometric dimensions of h = 9 mm and L = 200 mm. The measured first-order symmetric mode resonance frequency is approximately 550 Hz.

[0072] Therefore, in this embodiment, the geometric dimensions of the target tourmaline sound-absorbing board are customized for the target noise frequency band to be absorbed, so as to improve the sound absorption and negative oxygen ion release effects.

[0073] Furthermore, through research, it is found that the larger the target tourmaline sound-absorbing board, the lower the resonance frequency of the board itself, showing a trend of quadratic decrease. For example, when the length and width of the board are doubled, the resonance frequency is reduced by four times.

[0074] S2. After determining the target tourmaline sound-absorbing board, determine the target distance between the target tourmaline sound-absorbing board and the target wall according to the target noise frequency. Specifically, step S2 includes:

[0075] S21. Take the target noise frequency as the second resonance frequency of the sound-absorbing component.

[0076] Actually, the second resonance frequency of the above-mentioned sound-absorbing component is the resonance frequency when the air in the cavity between the target tourmaline sound-absorbing board and the target wall resonates.

[0077] S22. Determine the target distance between the target tourmaline sound-absorbing board and the target wall according to the second resonance frequency.

[0078] Specifically, the following formula (3) is satisfied among the second resonance frequency, the target distance between the target tourmaline sound-absorbing board and the target wall:

[0079] δL = c / 4f · (3)

[0080] Wherein, δL is the target distance between the target tourmaline sound-absorbing board and the target wall, f is the second resonance frequency, and c is the sound propagation speed in the air. Usually, c = 343 m / s.

[0081] Therefore, by adjusting the above distance δL, the resonance frequency of the air in the cavity between the target tourmaline sound-absorbing board and the target wall reaches the target noise frequency. When the sound-absorbing component is in the target noise environment to absorb the target noise, the air in the cavity between the target tourmaline sound-absorbing board and the target wall reaches the resonance state. In this resonance state, the vibration velocity of the gas particles in the target tourmaline sound-absorbing board increases, resulting in increased friction in the board. The increased pressure on the tourmaline material brings an increase in the polarization voltage, and the polarization voltage ionizes oxygen molecules and water molecules in the air to generate negative oxygen ions, thereby increasing the generation amount of negative oxygen ions.

[0082] Therefore, in this embodiment, the target distance between the target tourmaline sound-absorbing panel and the target wall is customized and designed for the target noise frequency band to be absorbed, and the sound absorption and negative oxygen ion release effects are improved through the air resonance between the distances.

[0083] S3. Following the above steps S1 and S2, adjust the telescopic frame so that the target tourmaline sound-absorbing panel is at a target distance from the target wall, so as to achieve resonance of the target tourmaline sound-absorbing panel and release negative oxygen ions.

[0084] Therefore, the method for manufacturing a sound-absorbing component for negative oxygen ion generation provided in this embodiment can be customized for the target noise frequency band to manufacture a tourmaline sound-absorbing panel that specifically absorbs the target noise and has better sound absorption effect and negative oxygen ion generation amount.

[0085] In the sound-absorbing component 100 for negative oxygen ion generation manufactured by the above manufacturing method, the telescopic frame 10 includes a first mounting portion 11, a second mounting portion 12, and at least a pair of telescopic rods 13 connected between the first mounting portion 11 and the second mounting portion 12. The first mounting portion 11 is connected to the target wall, the second mounting portion 12 is a free end, and the target tourmaline sound-absorbing panel 20 is mounted on the second mounting portion 12. It should be noted that, in order to improve the structural stability, the first mounting portion 11 and the second mounting portion 12 include multiple groups, such as four groups.

For the convenience of description, in this embodiment, the target tourmaline sound-absorbing panel 20 is taken as a square as an example for further description. Exemplarily, the geometric dimensions of the target tourmaline sound-absorbing panel 20 are 10 cm * 10 cm * 0.5 cm or 20 cm * 30 cm * 0.5 cm.

[0087] Further, the second mounting portion 12 includes a hollow closed-loop structure that is matingly connected to the outer edge of the target tourmaline sound-absorbing panel 20, and the second mounting portion 12 is arranged parallel to the target wall. When the target tourmaline sound-absorbing panel 20 is square, the second mounting portion 12 is a hollow rectangular frame. The target tourmaline sound-absorbing panel 20 is embedded in the second mounting portion 12, and the second mounting portion 12 is provided with a plurality of positioning holes 14, and the positioning holes 14 are opened on the outer peripheral surface of the second mounting portion 12. The sound-absorbing component 100 further includes a fastener (not shown in the figure) that passes through the positioning holes 14 and is connected to the target tourmaline sound-absorbing panel 20.

[0088] The fixation of the target tourmaline sound-absorbing panel 20 can be achieved by screwing through the positioning holes 14.

[0089] The telescopic rod 13 is a structure that can reciprocate in the same direction arbitrarily, including but not limited to any form such as push-pull type, slide rail type, sliding groove type, sliding rod type, etc. Preferably, in this embodiment, the sliding rod type structure is adopted, that is, the telescopic rod 13 includes a first connecting rod 131, a second connecting rod 132 and a fixing member 133. Among them, the first connecting rod 131 is connected to the first mounting portion 11, and the second connecting rod 132 is connected to the second mounting portion 12. The second connecting rod 132 is movably connected to the first connecting rod 131 through the fixing member 133, and the second connecting rod 132 can move axially along the first connecting rod 131. The fixing member 133 vertically penetrates through the first connecting rod 131 and the second connecting rod 132 to fix the positions of the first connecting rod 131 and the second connecting rod 132. Of course, corresponding slots or openings are respectively provided on the first connecting rod 131 and the second connecting rod 132 for the positioning of the penetration of the fixing member 133.

[0090] Exemplarily, the first connecting rod 131 and the second connecting rod 132 are respectively provided with long holes 134 arranged axially, and the fixing member 133 movably penetrates through the long holes 134 to fix the first connecting rod 131 and the second connecting rod 132.

[0093] Further, when the sound-absorbing component manufactured by the method for manufacturing a sound-absorbing component for negative oxygen ion generation is applied to a sound-absorbing device, the sound-absorbing device is a sound-absorbing wall, etc.

[0094] During use, when the sound-absorbing environment changes, that is, when the target noise frequency band changes, the size of the target tourmaline sound-absorbing panel and the distance between the target tourmaline sound-absorbing panel and the target wall can be adjusted to adapt to the new sound-absorbing environment and requirements.

[0095] In summary, the tourmaline sound-absorbing panel manufactured by the method for manufacturing a sound-absorbing component for negative oxygen ion generation provided in this embodiment can perform targeted sound absorption on the target noise frequency in the current sound-absorbing environment to achieve customized setting of the sound-absorbing component.
