Abstract
The utility model discloses a stereo diffusion acoustic board. The stereo diffusion acoustic board of the utility model is parallelly equipped with at least a deep groove and at least a shallow groove along the length direction on the main body plate front, at least a hole which piercing the plate thickness is arranged on a groove bottom of each deep groove, an opposite side of the main body plate is corresponding to each hole to form a counterbore. The utility model discloses a stereo diffusion acoustic board which has the advantages of reasonable structure, strong surface integrity, good sound-absorbing and sound insulation effect.
Description
Technical field
The utility model relates to a kind of acoustical board, is specifically related to a kind of solid diffusion acoustical board of architectural decoration.
Background technology
Present multi function hall, recording room, concert hall etc. are to there being specific (special) requirements to acoustically effective, people endeavour to develop many sound absorption acoustical insulation products, sound absorption acoustical insulation products on the market is varied, wherein existing mineral wool sound absorption board, perforated metal panel etc. all have sound absorption, but acoustically effective still can not be satisfactory.
Summary of the invention
The utility model provides a kind of solid diffusion suction disc with good sound absorption soundproof effect at the problems referred to above.
In order to achieve the above object, the utility model is by the following technical solutions:
Three-dimensional diffusion acoustical board described in the utility model is characterized in that: goes up along its length in the main board front, and at least one dark groove and at least one shallow grooves that be arranged in parallel, the bottom land of each dark groove has at least one to run through the hole of thickness of slab.
Corresponding each hole of aforementioned body backboard face forms counterbore.
Between two dark grooves, have and be no less than one shallow grooves.
Perhaps between two shallow grooves, have and be no less than one dark groove.
Above-mentioned groove is square groove, half slot, U-lag, V-shaped groove or other irregularly shaped groove.
Be to arrange in order between the above-mentioned hole, also can be unordered irregular alignment; The hole is circular, square or other is irregularly shaped.When the hole on above-mentioned each dark groove was arrangement in order, each dark groove upper groove surface can form the groove in each hole of connection.
The aforementioned body plate is that fiberboard, rubber and plastic boards, wood are moulded plate, rubber tile or gypsum plank.
Three-dimensional diffusion acoustical board described in the utility model, its positive reflection high frequency of going up, during back side counterbore absorbs, low frequency, it is worked in coordination and has good sound absorption soundproof effect.The utility model is the solid diffusion acoustical board that a kind of globality rational in infrastructure, surperficial is strong and the sound absorption soundproof effect is good.
Description of drawings
Fig. 1 the utility model embodiment one elevation;
Fig. 2 the utility model embodiment one rear elevation;
Fig. 3 the utility model embodiment one upward view;
Fig. 4 the utility model embodiment one A-A face sectional view.
The utility model is described in further detail below in conjunction with accompanying drawing:
The specific embodiment
Embodiment one
Shown in Fig. 1,2,3 and 4, on main board 1 length direction, two dark grooves 2 and two shallow grooves 3 be arranged in parallel, article two, shallow grooves 3 is set in parallel between two dark grooves 2, above-mentioned groove is square, at the bottom land of dark groove 2 hole 4 of running through thickness of slab is arranged, and corresponding each hole 4, main board 1 back side forms counterbores 5, mainboard body 1 back side covers one deck damping material (drawing among the figure), and main board 1 can be moulded plate, rubber tile or gypsum plank etc. for fiberboard, rubber and plastic boards, wood.
Embodiment two
On the main board length direction, be arranged in parallel two dark grooves and two shallow grooves, two dark grooves are set in parallel between two shallow grooves, and other is as described in the embodiment one.
The main board front is provided with dark relatively groove and shallow grooves, be to have the different reflection of sound, diffusion effect and concrete the setting according to different groove depth, and the different assimilation effects that will be different to the different frequency sound generating of the pore size of hole and counterbore, the degree of depth and arrangement, size, the degree of depth and the arrangement of the concrete shape of therefore dark groove and shallow grooves and arrange in pairs or groups between them arrangement mode and hole and counterbore can need and be set by concrete condition.And when the hole on above-mentioned each dark groove was arrangement in order, then each dark groove upper groove surface can form the groove in each hole of connection, and its diffusion acoustically effective is even more ideal.
The foregoing description one and two has only been represented the utility model two embodiments wherein, and the utility model is not limited thereto a little specific examples.
