Description

Sound-absorbing decorative plate

Technical Field

The utility model relates to a dalle technical field, the more specifically sound decorative board that inhales that says so.

Background

A novel material, namely a sound-absorbing board, appears in the field of decorative boards, and the sound-absorbing board is a plate-shaped material with the functions of sound absorption and noise reduction.

The principle of the sound absorbing plate is as follows: the surface of the sound-absorbing board is provided with a plurality of small holes, sound can be reflected in the inner wall of the sound-absorbing board in a messy way after entering the small holes, until most of the energy of sound waves is consumed, the sound waves are changed into heat energy, and the sound-absorbing effect is achieved.

At present, the effect of sound-absorbing boards on the market is not ideal, although a plurality of sound-absorbing holes are arranged on some sound-absorbing boards, sound is not reflected in disorder in the inner wall until extinction according to an ideal state, but the pocket rotates and runs out, so that the sound-absorbing hole structure can be realized by a plurality of optimized schemes.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome the defect more than prior art, provide an intensity height, indeformable, handsome in appearance, the third dimension is strong, decorative effect is good, sound effect is good inhales the sound decorative board.

In order to achieve the above purpose, the utility model discloses a realize through following technical scheme: the utility model provides a inhale sound decorative board, includes the composite fire prevention panel layer, inhales sound core plate layer and the fire prevention bottom plate layer that is in the same place of order, its characterized in that, the fire prevention panel layer is arranged by the equidistant separation of the PLASTIC LAMINATED of a plurality of strip column structures and is formed, adjacent two the separation between the PLASTIC LAMINATED is formed with one and leads the sound groove, it all is open state to lead the both ends mouth of sound groove length direction, every it all is provided with a plurality of edge on the sound core plate layer that inhales that the sound groove length direction was arranged exposes the face to lead that the sound groove bottom corresponds inhale sound hole, every the opening diameter of inhaling the sound hole all is greater than its correspondence lead the groove width in sound groove, every inhale the interior bottom in sound hole and all not have a perfect understanding inhale sound core plate layer, fire prevention bottom plate layer comprises the.

The utility model discloses the three-layer is compound, and the material of every layer all is the material that intensity is high, non-deformable, and alternate PLASTIC LAMINATED who arranges forms the panel moreover, and handsome in appearance, the third dimension is strong, decorative effect is good, inhales the sound hole as the blind hole design, by the throat design of leading the sound groove again, can lock more sound and disappear in the inside, promotes sound absorbing effect.

Preferably, inhale the sound core layer and inhale the sound core layer complex by first sound core layer and second and form, wherein all inhale the sound hole and all run through to arrange on the first sound core layer of inhaling, every inhale the sound hole and all be the loudspeaker column structure that the opening progressively enlarges, the sound core layer complex is inhaled to the second is in hide the face shutoff and block up all big openings of inhaling the sound hole on the first sound core layer of inhaling.

In order to promote sound absorption effect, inhale the sound hole and make the big loudspeaker column structure of the little inner bottom of outer mouthful, can better drip and pin sound, but the good drawing of patterns of the big loudspeaker column structure of this kind of little inner bottom of outer mouthful should not make, so the utility model discloses the innovation is compound with two-layer panel, and the one deck is as the trompil board, and the one deck is as sealing the board, so above-mentioned problem of ingenious solution.

Preferably, the first and second sound-absorbing core layers are each formed of a one-piece sheet-structured wood wool sound-absorbing sheet.

As preferred, inhale one of them side edge of sound core plate layer and cave in fire prevention core plate layer and fire prevention bottom plate layer, wherein inhale the sunken step degree of depth that sound core plate layer and fire prevention panel layer formed and be greater than inhale the sunken step degree of depth that sound core plate layer and fire prevention bottom plate layer formed, correspondingly inhale the protruding in fire prevention core plate layer and fire prevention bottom plate layer of this offside edge of sound core plate layer, wherein inhale the protruding step height that sound core plate layer and fire prevention panel layer formed and be less than the protruding step height that sound core plate layer and fire prevention bottom plate layer formed.

Has the advantages that: the utility model discloses the three-layer is compound, and the material of every layer all is the material that intensity is high, non-deformable, and alternate PLASTIC LAMINATED who arranges forms the panel moreover, and handsome in appearance, the third dimension is strong, decorative effect is good, inhales the sound hole as the blind hole design, by the throat design of leading the sound groove again, can lock more sound and disappear in the inside, promotes sound absorbing effect.
