Description
Technical field
The utility model relates to building interior decoration Acoustic treatment technical field, is specifically related to a kind of diffusion acoustic(al)absorbent that can realize sound wave diffusion and absorption.
Background technology
In the building interior decoration space of all kinds of sound recordings and playback, for example: in the interior decoration spaces such as recording room, control room, audiovisual studio, home theater, the design and the processing of indoor tone quality is absolutely necessary.We when moulding the sound field environment, make sound field diffusion evenly, low-frequency band absorbs fully as an important project of building, help the pure of tonequality and improve.
As you know, compare with smooth reflecting surface, the diffuser of different structure can effectively be avoided sound focus.After sound wave was through smooth metope reflection, all acoustic energy all will be along same direction reflection, and its reflection direction is fixed, and depends on the position of sound source.And after sound wave was through the diffuser surface reflection with different structure, acoustic energy will be by minute scattered reflection to different directions, and had different phase differences.These random scatters sound that form homogeneous energies can make that people's ear is subjective to produce a kind of spatial impression, can improve the sound degree that " becomes clear " when being used in the medium-high frequency diffusion simultaneously.At present various at the diffuser pattern that occurs on the market, still, all exist certain deficiency aspect the absorption of the low-frequency band that in to the sound field environment, exists, need come by the acoustic(al)absorbent of special use the absorption of low-frequency sound wave is handled toward contact.
A kind ofly can realize sound wave diffusion time, the appearance of the device that can also centering low-frequency sound wave wave band effectively absorbs seems extremely necessary.
The utility model content
The technical problem that the utility model solved is to provide a kind of simple in structure, science, and can absorb the diffusion acoustic(al)absorbent of sound wave low frequency again in usable reflection diffuse sound may sound wave.
The technical problem that the utility model solved realizes by the following technical solutions:
A kind of diffusion acoustic(al)absorbent, comprise diffusion sound absorption unit and substrate, described diffusion sound absorption unit is fixed on the described substrate, the back side at described substrate is provided with suspension member, it is characterized in that: each described diffusion sound absorption unit all is to become to have the polyhedron or the spherical surface body of cavity structure by the polylith thin plate splicing, or column, or cone, be closely seamless linking to each other between the bottom of each described diffusion sound absorption unit and the described substrate, and make between each described diffusion sound absorption unit and the described substrate and form closed cavity, also evenly be coated with one deck environmental protection paint at the external surface of described thin plate.
Described gauge of sheet is mainly 6 millimeters between 1 millimeter-10 millimeters, described thin plate is surface plate or curved slab.
Described environmental protection paint is the environment-protective nitrocellulose lacquer, has smooth surface after the spraying, helps the reflection of sound wave.
Principle of the present utility model is: sound wave is when the polyhedron with closed cavity structure that propagates into the polylith thin plate splicing one-tenth that is coated with lacquer by surface spraying environment-protective nitrocellulose or spherical surface body or column or cone diffusion sound absorption unit, and sound waves of different frequencies will reflect to different directions; Simultaneously, utilize the principle of thin plate resonance and closed cavity sound absorption, the wave band of different frequency is effectively absorbed, the frequency of sound wave of the dark more absorption of airtight cavity is just low more, otherwise just high more.
The beneficial effect that the utlity model has is: not only simple in structure, and also diffusion and sound-absorbing effect are obvious.When optimizing the sound uniformity, effectively eliminated reverberation, improved the definition of sound and hearer's comfort level.
