Abstract
The utility model discloses a hole wood acoustic baffle, its characterized in that, it includes fine board in the wooden veneer that sets up from last down layering and the fire prevention, and wooden veneer sets up a plurality of through -holes no. 1, and fine board is provided with a plurality of and the through -hole no. 2 through -hole monogamy in the fire prevention. The utility model discloses simple structure, it is effectual to absorb sound, can keep the visual effect of wooden decorative cover.
Description
Technical field
This utility model relates to technical field of construction and decoration materials, especially relates to a kind of wooden acoustic board.
Background technology
Along with commercial production, transportation, the development of urban architecture, and the increase of population density, increasing of home amenity, pollution from environmental noise is the most serious, it has become the big public hazards polluting human society environment, noise has locality, temporary and multiple feature, and noise not only can affect audition, but also has a negative impact the cardiovascular system of people, nervous system, hormonal system；Along with growth in the living standard, absorbing sound and lowering noise has been an important reference index of construction material.Wooden acoustic board is to process according to Principles of Acoustics exquisiteness, it is broadly divided into groove wood acoustic board and hole wood acoustic board, can be applicable to cinema, music hall, museum, exhibition center, library, family's noise reduction etc. and acoustic enviroment is required the higher and place of top grade decoration.If patent announcement number is CN203782909U, invention entitled sound-absorbing composite board, it includes micropore acoustic board, the back side of micropore acoustic board, is bonded with wood wool acoustic board.Above-mentioned sound-absorbing composite board, owing to being combined with micropore acoustic board by wood wool acoustic board, can not only raise the sound sucting band of microwell plate, strengthen the medium-high frequency sound absorbing capabilities of microwell plate, moreover it is possible to improve the acoustically effective of microwell plate.But, micropore acoustic board is usually and is made up of density board, during as the decorated wall surface in place, compared with wooden facing, lacks elegant visual effect, can not meet people's requirement to decoration.The surface ratio being additionally, since wood wool acoustic board is rougher, and micropore acoustic board is difficult to be firmly bonded with wood wool acoustic board, and stability is relatively poor.
Summary of the invention
The one that the purpose of this utility model is contemplated to solve the deficiency of prior art and provides is not only simple in structure, and acoustically effective is good, production and processing convenient hole wood acoustic board.
This utility model is to use following technical solution to be attained in that a kind of hole wood acoustic board, it is characterized in that, it includes that wooden facing and the fireproof medium-density fiberboard being layered setting from top to bottom, wood facing arrange multiple through hole one, and fireproof medium-density fiberboard is provided with multiple through hole two corresponding with through hole one.
Further illustrating as such scheme, the diameter of described through hole two is more than through hole one, and through hole one connects through hole two to form up-small and down-big big aperture sound absorption structure.
Described through hole two is 1-20:1 with the diameter proportion of through hole one.
Further, the centre-to-centre spacing between adjacent two through hole two is 10-35mm.
Further, through hole one one through hole two of corresponding connection.
Further, one through hole two of the corresponding connection of two or more through holes one.
This utility model uses above-mentioned technical solution can reach to provide the benefit that:
This utility model uses in the fireproof medium-density fiberboard surface configuration one layer with loose structure with the wooden facing of loose structure, is coordinated by the connection of two-layer through hole, not only can effectively eliminate noise, but also can keep the visual effect of good wooden decorative cover.

Description of reference numerals: 1, wood facing 1-1, through hole 1, fireproof medium-density fiberboard 2-1, through hole two.
Detailed description of the invention
As Figure 1-Figure 4, this utility model is a kind of hole wood acoustic board, and it includes that wooden facing 1 and the fireproof medium-density fiberboard 2 being layered setting from top to bottom, wood facing arrange multiple through hole one 1-1, fireproof medium-density fiberboard is provided with multiple through hole two 2-1 corresponding with through hole one, and through hole one connects through hole two.Described through hole two is 1-20:1 with the diameter proportion of through hole one.It is to say, through hole two exists equal situation with the diameter of through hole one, or the diameter of through hole two is more than through hole one, forms up-small and down-big big aperture sound absorption structure, and the centre-to-centre spacing between adjacent two through hole two is 10-35mm.
Below in conjunction with specific embodiment, the technical program is explained in detail.
Embodiment 1
As in figure 2 it is shown, in the present embodiment, the through hole of wood facing and fireproof medium-density fiberboard is evenly distributed, through hole one one through hole two of corresponding connection.The diameter of through hole one, equal to the diameter of through hole two, is 6mm；The centre-to-centre spacing of adjacent two through hole is 16mm, and its punching rate is 11%.
Embodiment 2
As it is shown on figure 3, in the present embodiment, the through hole of wood facing and fireproof medium-density fiberboard is evenly distributed, through hole one one through hole two of corresponding connection.The diameter of through hole one is less than the diameter of through hole two, and a diameter of 5mm of through hole one, a diameter of 12mm of through hole two, through hole centre-to-centre spacing is 16mm, and punching rate is 7.7%.Embodiment 3
As shown in Figure 4, in the present embodiment, the through hole of wood facing and fireproof medium-density fiberboard is evenly distributed, 4 through hole one one through holes two of corresponding connection.A diameter of 1.2mm of through hole one, a diameter of 6mm of through hole two, through hole centre-to-centre spacing is 16mm, and punching rate is 4%.
The technical program is compared with prior art, use in the fireproof medium-density fiberboard surface configuration one layer with loose structure with the wooden facing of loose structure, coordinated by the connection of two-layer through hole, not only can effectively eliminate noise, but also the visual effect of good wooden decorative cover can be kept.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
