The utility model is characterized in that: a plurality of sound absorption through holes are arranged on a plate; the hole diameter of each sound absorption through hole on the forward sound face is larger than the hole diameter of each sound absorption through hole on the rear sound face, thereby sound wave feedback approaches can be significantly reduced through the change of hole diameters after sound waves enter into the sound absorption through hole, and the best sound absorption efficiency is then achieved.
Description
Technical field
The utility model relates to a kind of decoration sound-absorbing sheet material.
Background technology
" sound " is caused by air vibration, so be called " sound wave " again, " sound-absorbing " then is to make the interior existing sound wave of unit space be able to be absorbed by suitable sound-absorbing object, to reduce the back coupling of this sound wave, this has absolute different with so-called " sound insulation ", because so-called " sound insulation " is meant sound is intercepted within a certain space, so substantial difference is arranged between the two; The utility model is innovation and the improvement of doing at " sound-absorbing " efficient of object.
Therefore, with regard to general scientific principle and practice means, common people normally utilize the member with careful hole as Sound-absorbing member, are listed below several materials now and summarize its good and bad point as follows:
One, sponge class object: the structurally flexible of this material and have countless holes own, also be good and the comparatively cheap main sound-absorbing material of cost, necessary rigidity requirement when only just not meeting decoration owing to this material is too soft, so it must be managed fixing also clamping in use on rigidity sheet material, right this adds fixing basic step with clamping plate, just lose its sound-absorbing effect in a large number in advance, moreover, this material water absorption character is splendid, so very easily absorb moisture and moisture in the space, and then cause the obstruction of hole and have a strong impact on its sound-absorbing effect, especially bad, this material can cause and cause corrosion in the short time eventually because of the existence of these moistures and moisture, damage and unbearably use.
Two, the sheet material of the circular perforation of tool: be to utilize the compacting of timber fibrid to form, be drilled with countless circular perforations on it, and has to a certain degree sound-absorbing usefulness, only because its perforation aperture is forward and backward identical, the path that sound wave is feedback again after entering is suitable, thereby can only cause some consumption of sound wave; In brief, if will make this type of sheet material have higher sound-absorbing efficient, then the thickness that must infinitely increase sheet material can progressively be obtained expected effect, and then significantly expend indoor utilized space, this the point, we can and inspect its wallboard thickness in professional places such as recording rooms, and just susceptible of proof creator's institute says.
Three, slag class sound-absorption hole stone (brick): be to utilize slag thing sintering to form, only because spacious day of processing procedure is time-consuming, cost high, and machining accuracy and quality are difficult for grasping, so large and small unpredictable in aperture, relatively use the good and the bad of its sound-absorbing efficient fully to control, thereby almost can not be as the usefulness of indoor decoration sound-absorbing sheet material, simultaneously, because of its quality is comparatively heavy, also the utmost point is unfavorable for transportation and construction again.
So, because above-mentioned every situation, the known sound-absorbing wallboard 30 that in the future has the dealer to develop is as shown in Figure 5 then constructed, and as known in the figure, it mainly lies in the deckle board 32 of a tool suitable thickness, and solid to follow closely, cohere or the high frequency mode of welding is installed with countless taper and the large and small sounder resonators that differ 34 of being, in order to do the front wide and rear narrow taper design that utilizes these sounder resonator 34 endoporus, with the feedback path of minimizing sound, and then obtain suitable sound-absorbing usefulness.
Certainly, though this conventional construction design really can reach preferable sound-absorbing efficient, but we only must inspect its structure a little and associate its processing procedure, just known the complexity of cognitive its processing procedure and loaded down with trivial details, such as the nail system of deckle board 32, the making of sound-absorbing tube 34, and even sound-absorbing tube 34 is fixedly arranged on the vast and numerous etc. of the inevitable degree of difficulty of deckle board 32 and quantity thereof, in that it can not fully meet the usability on economic benefit and the industry at susceptible of proofs all.
Summary of the invention
The purpose of this utility model is to provide a kind of decoration structural improvement sound-absorbing sheet material, and it not only is easy to processing and manufacturing, and low cost of manufacture can obtain splendid sound-absorbing efficient simultaneously again.
For achieving the above object, solution of the present utility model is: utilize the sheet material with suitable rigidity, directly offer numerous sound-absorbing perforations more thereon, and make each sound-absorbing perforation be positioned to the aperture of sound face perseverance greater than the aperture that is positioned at back of the body sound face, after making sound wave enter the sound-absorbing perforation, can significantly reduce the approach of feedbacking by the variation in aperture, thereby obtain best sound-absorbing efficient, simultaneously can significantly reduce processing procedure and procedure of processing again, except that reducing manufacturing cost at one stroke and enhancing productivity, more and then really met the value on the specific industry.

Fig. 2 is the partial cutaway schematic of the utility model one preferred embodiment.
Fig. 3 is the partial cutaway schematic of another preferred embodiment of the utility model.
Fig. 4 is the partial cutaway schematic of the another preferred embodiment of the utility model.
Fig. 5 is the structural representation of known sound-absorbing wallboard.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model is directly to offer numerous sound-absorbing perforations 20 on a sheet material 10 in design, and make each sound-absorbing perforation 20 be positioned to the aperture of sound face 12 22 perseverances greater than the aperture 24 that is positioned at back of the body sound face 14, thereby after being made sound wave enter this sound-absorbing perforation 20, can be by the variation in aperture 22,24, and significantly reduce the approach that sound wave is feedback, and then reach best sound-absorbing efficient, the usefulness on wallboard, ceiling or floor when being able to as indoor decoration.
So, according to same design scientific principle and user demand, then the utility model can impose as Fig. 2,3,4 indivedual or mix design, and make sound-absorbing perforation 20 become the special shape design of fish-eye shaped, taper or helical form etc. respectively, be easy to processing and fabricating, with low cost and can obtain the actual finished product of splendid sound-absorbing efficient and equally still have.
At last, the creator must emphasize once more, arbitrary sound-absorbing all has its sound-absorbing effect to a certain degree with material, its difference only just the height of sound-absorbing efficient have nothing in common with each other, in brief, when with the sheet material (figure does not show) of the utility model of same thickness and the circular perforation of traditional tool when comparing, sound-absorbing efficient of the present utility model will be higher than this and commonly use product more than 40% (already through experiment confirm), that is to say, this is commonly used product and applies the sound-absorbing metope when the desire utilization, and when desire obtained the sound-absorbing efficient suitable with the utility model, then it just must increase its thickness side and is achieved one's goal and reach, but the utility model there is no misgivings in this respect; In like manner, when Sound-absorbing member is done synthetical comparison and assessment shown in the case before with the utility model and aforesaid two patent citations, though on sound-absorbing efficient, may not have too big difference, but the absolute predominance of economic benefit aspects such as the owning cost of the utility model desire is cheap it serves to show that practicality of the present utility model and industry applications are superior really.
