Abstract
The utility model relates to a sound-absorbing panel which comprises panel layers, sound-absorbing layers and bottom plate layers which are stacked in sequence, wherein each sound-absorbing layer consists of at least two sound-absorbing panels and one sound-absorbing bottom plate, a plurality of sound-absorbing holes are formed in each sound-absorbing panel, the sound-absorbing holes of adjacent sound-absorbing panels are communicated, the diameter of each sound-absorbing hole facing the panel layer is larger than the diameter of each sound-absorbing hole facing the bottom plate layer, and the sound-absorbing bottom plate is arranged between each sound-absorbing panel and the bottom plate layer. The utility model has the advantages that: the sound absorption holes on the sound absorption plate are mutually communicated to form a silencing channel, so that sound waves are continuously reflected in the silencing channel, and the sound waves are difficult to reflect out of the silencing channel due to the small size of the large tail part of the opening of the suction hole.
Description
Technical Field
The utility model relates to the technical field of decorative boards, in particular to a sound-absorbing panel.
Background
The field of decorative boards is a new and expensive material, namely a sound-absorbing board, which is a platy material with sound-absorbing and noise-reducing effects, and a wooden sound-absorbing board is finely processed according to an acoustic principle and consists of a facing, a core material and a sound-absorbing thin felt.
Principle of the acoustic panel: the surface of the sound absorbing plate is provided with a plurality of small holes, after sound enters the small holes, the sound can be reflected in a messy way in the inner wall of the structure like a sponge until most of the energy of sound waves is consumed, and the sound energy is changed into heat energy, so that the sound insulation effect is achieved.
At present, the effect of the acoustic boards on the market is not ideal, and although a plurality of acoustic holes are arranged on some acoustic boards, sound is not reflected in the inner wall in a mess according to an ideal state until the sound is eliminated, but the sound is rotated and runs out.
Disclosure of Invention
The utility model mainly solves the problems and provides the sound-absorbing panel.
The technical scheme adopted by the utility model for solving the technical problems is that the sound-absorbing panel comprises a panel layer, a sound-absorbing layer and a bottom plate layer which are stacked in sequence, wherein the sound-absorbing layer consists of at least two sound-absorbing panels and a sound-absorbing bottom plate, a plurality of sound-absorbing holes are formed in the sound-absorbing panels, the sound-absorbing holes of adjacent sound-absorbing panels are communicated, the diameter of the sound-absorbing holes facing the panel layer end is larger than the diameter of the sound-absorbing holes facing the bottom plate layer end, and the sound-absorbing bottom plate is arranged between the sound-absorbing panels and the bottom plate layer.
The sound absorption holes on the sound absorption plate are mutually communicated to form a silencing channel, so that sound waves are continuously reflected in the silencing channel, and the sound waves are difficult to reflect out of the silencing channel due to the small size of the large tail part of the opening of the suction hole.
As a preferable mode of the above-mentioned mode, the panel layer is a vitrified microsphere plate.
As a preferable aspect of the above aspect, the sound absorbing board is a perforated gypsum board or a glass fiber cotton board.
As a preferable mode of the above-mentioned scheme, the sound absorbing bottom plate is perforated gypsum or glass fiber cotton plate.
As a preferable mode of the above-mentioned scheme, the bottom plate layer is a nonwoven fabric or a glass fiber felt.
As a preferable scheme of the scheme, the sound-absorbing bottom plate and the sound-absorbing plate are arranged in a staggered mode, and the edge of the sound-absorbing bottom plate and the sound-absorbing holes are arranged in a staggered mode.
The utility model has the advantages that: the sound absorption holes on the sound absorption plate are mutually communicated to form a silencing channel, so that sound waves are continuously reflected in the silencing channel, and the sound waves are difficult to reflect out of the silencing channel due to the small size of the large tail part of the opening of the suction hole.

Detailed Description
The technical scheme of the utility model is further described below through examples and with reference to the accompanying drawings.
Examples:
this embodiment of an acoustic panel, as shown in fig. 1, the package stacks panel layer 1, sound absorbing layer and bottom plate layer 5 in proper order, the sound absorbing layer comprises two piece at least acoustic panels 2 and a sound absorbing bottom plate 4, the array has a plurality of sound absorbing holes 3 on the acoustic panel 2, the sound absorbing holes 3 of adjacent acoustic panel 2 are linked together and are formed the sound absorbing passageway, the diameter of sound absorbing holes 3 towards panel layer 1 end is greater than the diameter towards bottom plate layer 5 end, the sound absorbing bottom plate 4 is located between acoustic panel and the bottom plate layer, sound absorbing bottom plate and acoustic panel dislocation set and sound absorbing bottom plate edge and sound absorbing hole dislocation set.
The sound-absorbing board 2 and the sound-absorbing bottom board 4 are perforated gypsum boards or glass fiber cotton boards, and the perforated gypsum boards and the glass fiber cotton boards can be used in any combination, namely the same board body can be used as the sound-absorbing board and the sound-absorbing bottom board, different board bodies can be used as the sound-absorbing board and the sound-absorbing bottom board, and the same board body can be used as the sound-absorbing board and the different board bodies can be used as the sound-absorbing board. The perforated gypsum board and the glass fiber cotton board have certain sound absorption effect, when sound waves contact the wall of the sound absorption hole, one part of the sound waves are absorbed by the perforated gypsum board and the glass fiber cotton board, and the other part of the sound waves are reflected, so that the purpose of sound absorption is achieved in two aspects, and the sound absorption effect is good.
In this embodiment, the panel layer 1 is a vitrified microsphere plate, and the bottom plate layer is a non-woven fabric or a glass fiber felt.
The acoustic panel in this embodiment can satisfy different acoustic demands by providing acoustic panels with different layers. The sound absorption holes on the sound absorption plates are mutually communicated to form the silencing channels which are alternately contracted and expanded, so that sound waves are continuously reflected in the silencing channels and are difficult to reflect out of the silencing channels, and the longer the silencing channels are, the better the silencing effect is.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
