Description
Technical field
It the utility model is related to a kind of combined puncturing sound-absorbing smallpox.
Background technology
In the prior art, perforated sound-absorbing smallpox as depicted in figs. 1 and 2, by the sheet material 10 with tank and is filled in tank
In acoustical cotton 30 form, tank bottom surface is horizontal, and tank bottom surface opens up perforation 20, makes when being laid on overhead room 40
Used time, the tank bottom surface of sheet material 10 is parallel with overhead room 40, can be to the sound of indoor different frequency range using different punching rates
Ripple has certain absorption, but sheet design easily causes the resonance of indoor low-frequency sound and produces clutter, and planar chip design is easy
The sound wave that the sound for allowing same sound generation source to send is not predominantly absorbed reflects toward same direction and produces standing wave indoors, so as to cause
The discomfort of sense of hearing.
In addition, existing perforated sound-absorbing smallpox typically uses plane smallpox or metope form, area is big, and surfacing,
Mode is averagely separated using the rear space of perforated sheet metal 10, the intensity of perforated sheet metal 10 is had higher requirements, is otherwise easily caused altogether
Shake, and unabsorbed sound easily reflects toward same direction, and designer generally requires to design many moulding and surfacing
Make up these deficiencies.
Utility model content
The purpose of this utility model is to provide a kind of combined puncturing sound-absorbing smallpox, suitable for the small space of audition, drilled
The sound-absorbing of environment is sung, makes space sound field totally clear.
In order to reach above-mentioned purpose, solution of the present utility model is：
Combined puncturing sound-absorbing smallpox, by it is some with tile mode assembly in the sound-absorbing module composition on overhead room,
Each sound-absorbing module is made up of the sheet material with tank and the acoustical cotton being filled in tank, each sound-absorbing module and room smallpox
Plate combines to form independent sound-absorbing cavity, and the bottom surface of tank is oblique, and tank bottom surface opens up perforation, and punching rate be 30% with
On.
The sound-absorbing module is overlooked square.It is of course also possible to it is designed as rectangle or other shapes.
Gap is left between the two neighboring sound-absorbing module to be tiled on the overhead room.
The sheet material of the sound-absorbing module has crisscross rib in tank.
The sheet material of the sound-absorbing module forms grab in tank top edge, forms hole clipping on corresponding overhead room, borrows
Help grab to coordinate with hole clipping, make the tiling assembly of sound-absorbing module on overhead room.Or the sheet material of the sound-absorbing module is holding
Groove top edge is using fastened by screw on overhead room.
After such scheme, the utility model utilizes different punching rates, can have one to the sound wave of indoor different frequency range
Fixed absorption, sound reflecting face is formed at the top of sound-absorbing cavity between sound-absorbing module and overhead room can allow sound by perforation
Ripple is reflected back acoustical cotton and absorbed again again, and so, the acoustic energy to come from different directions can repeatedly be absorbed, and
It is designed as having certain oblique angle with ceiling below sound-absorbing module, can also be reflected without absorbed sound toward different directions
Go, so as to destroy the condition that sound standing wave is produced in room；Through overtesting, whole overhead room face is accounted for when sound-absorbing module is taped against
When long-pending more than 40%, room becomes peace and quiet, and sound standing wave significantly reduces in room, and all sound become very clear.
The utility model is applied to the small space of audition, sings the sound-absorbing of environment, makes space sound field totally clear.

Label declaration
Sheet material 10, perforation 20, acoustical cotton 30, overhead room 40；
Sound-absorbing module 1, perforation 11, tank 12, sheet material 13, acoustical cotton 14, rib 15, grab 16, overhead room 2.
Embodiment
As shown in Figures 3 to 8, the combined puncturing sound-absorbing smallpox that the utility model discloses, is spelled by some with tile mode
Formed loaded on the sound-absorbing module 1 on overhead room 2.
Each sound-absorbing module 1 is made up of the sheet material 13 with tank 12 and the acoustical cotton 14 being filled in tank 12, each
Sound-absorbing module 1 combines to form independent sound-absorbing cavity with overhead room 2, and the bottom surface of tank 12 is oblique, the bottom surface of tank 12
Perforation 11 is opened up, and punching rate is more than 30%.
Further, sound-absorbing module 1 is overlooked square（It may be designed in rectangle or other shapes）, with convenient-laying
And assembly.Gap is left between the two neighboring sound-absorbing module 1 to be tiled on overhead room 2.The sheet material 13 of sound-absorbing module 1 is holding
There is crisscross rib 15 in groove 12, increase intensity, reduce resonance.The sheet material 13 of sound-absorbing module 1 is in the top of tank 12
Edge forms grab 16, and hole clipping is formed on corresponding overhead room 2（Not shown in figure）, coordinate by grab 16 and hole clipping, make
Sound-absorbing module 1 tiles assembly on overhead room 2.Certainly, sound-absorbing module 1 can also use fastened by screw in overhead room
On 2.
The utility model can absorb a part by sound-absorbing cavity independent between sound-absorbing module 1 and overhead room 2
From singer direction by air borne come alt acoustic energy；After sound passes through perforation 11, absorbed, remain by acoustical cotton 14
Under through acoustical cotton 14 sound reflected by ceiling 2 after absorbed again by acoustical cotton 14（As shown by arrows）, so, from difference
The acoustic energy that direction comes can repeatedly be absorbed, and sound-absorbing module 1 is designed as having certain oblique angle with ceiling 2 below,
There is no absorbed sound to be reflected away toward different directions, so as to destroy the condition for producing sound standing wave in room.
Through overtesting, when the sound-absorbing module 1 of overhead room 2 is taped against account for whole ceiling area more than 40%, room
Become peace and quiet, sound standing wave significantly reduces in room, and all sound become very clear.
Utility model works procedure declaration：
A. first identical model as Figure 6-Figure 8 is made, it is corresponding to be installed on overhead room with the moderate iron plate of thickness
Position it is as shown in Figure 5；
B. the quantity of adjusting module model, spacing and horizontal rotatio direction are optimal to sense of hearing and recording effect；
C. the natural reverberation time in test room, the frequency response uniformity, the sound field uniformity；
D. mold, the density of adjustment plastics die casting, the natural reverberation time by, the frequency response uniformity, sound field is uniform
Degree is adjusted to consistent with iron plate model.
The utility model compared with the prior art, through overtesting, because the reduction of standing wave, the sound in the whole room in room
Natural reverberation has clear improvement, and clear sound is quiet, due to the raising of definition, control of the singer to sound, rhythm and
The judgement of melody is easier, and performance becomes free and relaxed；Because the reduction of standing wave, the audio signal into recording does not have muddiness
Feel, acoustic background also becomes clean, and recording effect is also obviously improved.
