Abstract
The utility model relates to a noise absorbing decorating material, with ripples on the surface, and through holes are positioned among the ripples. The utility model is a decorating noise absorbing material formed by adopting medium, and high density fiberboard. The main technique proposal includes semicircle shaped ripples on the surface of the medium and high density fiberboard and the through holes distributed between the ripples. The utility model is characterized in that: the surface of the medium and high density fiberboard is distributed with averagely semicircle shaped ripples and the through holes for absorbing the sound are arranged between the ripples, and the surface is decorated by the paint. The utility model has the advantages that: the utility model can prevent the straight reflection of the sound and make the sound evenly distributed, make the tone more plump, more clear and abundant with space perception and synchronously the utility model has good decorating effect.
Description
Technical field
The utility model belongs to a kind of decoration damping material, especially a kind of middle and higher density fiberboard abatvoix with ripple and perforation is mainly used in indoor furred ceiling, decorative wall panels, sound-absorbing furred ceiling and wallboards industrial and civilian construction (as theater, movie theatre, assembly hall, hotel, residential houses etc.).
Background technology
Most of perforation and the straight flute of adopting of existing abatvoix, outward appearance is simple, and its sound-absorbing principle mainly is to utilize perforation and groove on the sheet material to form resonance sound-absorbing structure, and the wave absorption that enters in it is fallen.When the resonance frequency of incident sound wave frequency and system was consistent, the air at perforation neck place produced fierce vibration friction, has strengthened sink effect, has formed absworption peak, and acoustic energy is significantly decayed.
But existing abatvoix is subjected to its structure influence, and to the reflection of sound, the even DeGrain that distributes, the applicant improves this for this reason.
Technology contents
The purpose of this utility model is on the basis of existing abatvoix, according to the principle of reflection of sound, designs and a kind ofly not only has sound-absorbing effect but also have the evenly decoration acoustic panel of distribution effect of sound.
Main technical schemes of the present utility model comprises the semicircle ripple on middle and higher density fiberboard surface and is distributed in microscler perforation between ripple.It is characterized in that on the surface of middle and higher density fiberboard uniform semicircle ripple being arranged, be useful on the microscler perforation of sound-absorbing between ripple, the surface adopts paint to decorate.
Described ripple is the concavo-convex semicircle moulding that is evenly distributed on the middle and higher density fiberboard.The perforation that is evenly distributed in the spill ripple is microscler perforation.The structure that is used for the adjacent sheet metal overlap joint is concavo-convex rabbet groove.
The utility model has the advantages that the microscler perforation between ripple has the attraction effect, and corrugated surface is when making sound wave arrive corrugated surface, the direction of its reflection has nothing in common with each other, can prevent the direct reflection of sound, sound is evenly distributed, tonequality is more plentiful, clear, be rich in third dimension, reduces noise, has good decoration effect simultaneously.
Description of drawings
Fig. 1 is a front view of the present utility model; Fig. 2 is an A-A sectional drawing of the present utility model.
The specific embodiment
As shown in the figure, the Surface Machining at middle and higher density fiberboard 1 goes out semicircle concavo-convex ripple, the crest 2 of protruding ripple and the trough 3 of recessed ripple, this shape can prevent the direct reflection of sound, sound is evenly distributed, and tonequality is more plentiful, clear, be rich in third dimension, reduces noise.Be evenly distributed on the microscler circle perforation in the trough 3, form resonance sound-absorbing structure, the wave absorption that enters in it is fallen with mounting baseplate, when the resonance frequency of incident sound wave frequency and system is consistent, the air at perforation neck place produces fierce vibration friction, has formed absworption peak, and acoustic energy is significantly decayed.The concavo-convex rabbet groove that is used for the adjacent sheet metal overlap joint can be guaranteed the planeness of sheet material installation and the uniformity of whole structure.
