Description
Technical field
The present invention relates to sound absorption material in a kind of modern architecture finishing, especially relate to a kind of cavity sound absorbing plate.
Background technology
Decorate at present both at home and abroad on sound absorption material is selected, employing be to have stronger absorption acoustic performance, the material of reducing noise performance.These materials by self porosity, membrane action or resonant interaction and incident acoustic energy is absorbed, do not accomplish the acoustic characteristic impedance coupling of sound absorption material and sound bearing medium on every side, enter sound absorption material with making the acoustic energy areflexia, and the incident acoustic energy overwhelming majority is absorbed.On large space, not clearly such as market, sports palace acoustically effective, the problem on the acoustics usually can appear.Such as sports palace, exhibition hall, railway terminal, Conference Hall, concert hall etc., architectural space increasing just brings many acoustic problems, can affect the use of building function such as long reverberation, sound focus, echo problem.To this, how to adopt innovative technology, new material, guarantee that architecture indoor effectively absorbs sound, architectural space inner language definition is improved, this problem need to be carried out case study.
Summary of the invention
The objective of the invention is: a kind of cavity sound absorbing plate is provided, can effectively solves the problem of the long reverberation that large space such as market, sports palace brings, sound focus, echo, guarantee that architecture indoor effectively absorbs sound, architectural space inner language definition is improved.
Technical scheme of the present invention is: a kind of cavity sound absorbing plate, and it comprises film, cavity dividing plate, backboard, and described cavity dividing plate is the Turbogrid plates structure, and a side of cavity dividing plate arranges film, and the another side of cavity dividing plate arranges backboard; The Turbogrid plates structure of cavity dividing plate has formed a plurality of internal cavities between film and backboard; The position of corresponding described internal cavity offers several ultramicropores on the described film.
The below is further expalined technique scheme:
The honeycomb grid plated construction that described cavity dividing plate is the hexagonal subelement, described internal cavity are the hexagonal cavity in cross section.
The depth of described internal cavity is 50～100mm.The depth of internal cavity can customize as required.
Described film is close on the cavity dividing plate.
Its thickness of described backboard is greater than 5mm.Backboard is close to the cavity dividing plate, forms overall structure.
Offer circular hole on the position of corresponding described internal cavity on the described backboard.
The aperture of described circular hole is half of internal cavity internal diameter.
Described ultramicropore is Small circular aperture, and the aperture is 0.2～0.8mm.The regularity of distribution of the corresponding internal cavity of the regularity of distribution of described circular hole, circular hole can be cancelled as required.
Described film is transparent membrane.
Described cavity dividing plate is lamina of septum pellucidum.
Described backboard is transparent panel.
Described film is the PC film.The cavity dividing plate is PC cavity dividing plate.Backboard is the PC backboard.
Advantage of the present invention is: cavity sound absorbing plate of the present invention, broken the use to traditional sound absorption material, by changing the various parameters of ultramicropore, solve the problem of the long reverberation that large space such as market, sports palace brings, sound focus, echo, guarantee that architecture indoor effectively absorbs sound, architectural space inner language definition is improved.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is side of the present invention bottom surface cross-sectional structure schematic diagram;
Fig. 2 is side end face cross-sectional structure schematic diagram of the present invention;
Fig. 3 is cross section of the present invention schematic diagram.
Wherein: 1 film; 2 ultramicropores; 3 internal cavities; 4 cavity dividing plates; 5 backboards; 6 circular holes.
The specific embodiment
Embodiment one:
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of cavity sound absorbing plate, it comprises film 1, cavity dividing plate 4, backboard 5, it is a kind of honeycomb board with internal cavity 3 structures.
The position of corresponding described internal cavity 3 offers several ultramicropores 2 on the film 1.Ultramicropore 2 is Small circular aperture, and the aperture is 0.2～0.8mm.The ultramicropore 2 that distributes on the film 1 and the combining structure of internal cavity 3 satisfy the structure of helmholtz resonance principle.
Offer circular hole 6 on the backboard 5 on the position of corresponding described internal cavity 3.The aperture of circular hole 6 is half of internal cavity 3 internal diameters.
The film 1 of present embodiment is transparent membrane.Cavity dividing plate 4 is lamina of septum pellucidum.Backboard 5 is transparent panel.Film is the PC film.The cavity dividing plate is PC cavity dividing plate.Backboard is the PC backboard.
Fig. 1 has reflected the spatial relationship of each parts and the distribution situation of ultramicropore 2.Fig. 2 has reflected circular hole 6 distribution situations of end face.Fig. 3 has reflected the structure of internal cavity 3.
Present embodiment is in practicing, can require to preset sound absorption frequency range and sound absorption coefficient according to the sound absorption of real space, various parameters to ultramicropore 2 are adjusted, ultramicropore 2 porosity general controls are 1%～3%, the aperture then is controlled between 0.2～0.8mm, can affect simultaneously the depth that also has internal cavity 3 of sound absorption coefficient, and whether internal cavity 3 is closed.
