Specific embodiment
As shown in Figure 1, 2, a kind of full range diffuser, including base plate 10, top board 20 and diffuser plate 30, the diffuser plate 30 is in
Long plate shape, the base plate 10 covers the bottom for being located at the diffuser plate 30, and the top board 20 covers the top for being located at the diffuser plate 30,
The front of the diffuser plate 30 offers the first groove 310, the second groove 320 and the 3rd groove 330, first groove 310
Depth of the depth more than second groove 320, the depth of the depth of second groove 320 more than the 3rd groove 330
Degree, first groove 310, the second groove 320 and the 3rd groove 330 extend to its bottom, and institute by the top of diffuser plate 30
State the length direction arranged for interval of the first groove 310, the second groove 320 and the 3rd groove 330 along diffuser plate 30.
By directly the front of diffuser plate 30 open up by the top of diffuser plate 30 extend to its first groove of bottom 310,
Second groove 320 and the 3rd groove 330, simple structure are easy to process, and the top of the diffuser plate 30 sets top board 20, institute
The bottom for stating diffuser plate 30 sets base plate 10, makes at the opening of the first groove 310, the second groove 320 and the two ends of the 3rd groove 330
Sealing, while depth of the depth of first groove 310 more than second groove 320, the depth of second groove 320
More than the depth of the 3rd groove 330, the sound wave of different frequency is spread by the groove of different depth, and it is high in diffuser plate 30
The sound wave of different frequency can be diffused by the first groove 310, the second groove 320 and the 3rd groove 330 in the range of degree so that
The diffusion of sound is more uniform, increases the spatial impression of sound, improves the definition of sound, and the full range diffuser is mainly used in individual
Movie theatre, qin room, parlor.
As shown in Figure 1, 2, the front of diffuser plate 30 described in the present embodiment offers two the first grooves 310, two second
Groove 320 and two the 3rd grooves 330, two the 3rd grooves 330 are separately positioned on the positive both sides of diffuser plate 30, two
Two grooves 320 are separately positioned on the positive middle part of diffuser plate 30, and two the first grooves 310 are separately positioned on different second grooves
Between 320 and different 3rd grooves 330, so setting preferably can spread the audio of different frequency, further increase sound
Spatial impression.First groove 310, the second groove 320 and the 3rd groove 330 interval are evenly arranged, further such that sound
Diffusion it is more uniform.The front both sides of diffuser plate 30, base plate 10 and top board 20 are provided with chamfering 40.
The diffuser plate 30 is QR diffuser plate, after sound wave is reflected by the surface of the diffuser plate 30, acoustic energy quilt
Dispersion is reflected towards different directions, plays a part of to break up acoustic energy, prevents echo and standing wave.
To ensure diffusion effect, the depth of the first groove 310 described in the present embodiment is 300mm-1700mm, is mainly used in low
The diffusion of frequency domain audio, the depth of second groove 320 is 50mm-300mm, is mainly used in the diffusion of middle frequency domain audio, described the
The depth of three grooves 330 is 5mm-50mm, is mainly used in the diffusion of high-frequency audio.To ensure diffusion effect and technological requirement, institute
The width of the first groove 310 is stated for 50mm-2000mm, the width of second groove 320 is 50mm-2000mm, the described 3rd
The width of groove 330 is 50mm-2000mm, a width of 1200mm*300mm of * long of diffuser plate 30 described in the present embodiment, in small space
The full range diffuser is inside can be used alone, in large space, can be used and multiple full range diffusers are stitched together
Use, room is bigger, can spell more multiple, reach more preferable diffusion effect.
The diffuser plate 30, base plate 10 and top board 20 are EPS plate of material, the base plate 10 and top board 20 respectively with diffusion
The hot-melt adhesive paste of plate 30.The outer surface of the diffuser plate 30, base plate 10 and top board 20 is all covered with GRG sprayed coatings.The full range spreads
With high density EPS as base material, the base material has light weight to body, the characteristics of easy processing shapes, is simulated by acoustic software and calculated
The overall figure of diffuser plate 30, required shape of product is once cut out using numerical control machine cutting technique to EPS, be compensate for
Be present the defect of leak in the shaping of tradition wood board splicing, then with numerical control machining base plate 10 and top board 20, incited somebody to action with thermosol technology
Each plate for cutting out is bonded, and finally in surface covering high intensity GRG sprayings, product is reached the acoustics of diffusion audio
Characteristic.GRG sprayed coatings make the full range diffuser have high intensity, high rigidity and good pliability, not cracky, deform and open
Split.The full range diffuser fire protecting performance is good, and weight only has 1/3rd of wood-based product, and Form aldehyde release is low, can meet various building
The environment of sound.The surface and inside of the full range diffuser are closed structure, and sound wave cannot be transmitted and wherein produce resonance, when sound wave enters
Diffusing reflection can be only formed when being mapped to 30 surface of diffuser plate, so as to produce diffusion effect, it is different from traditional wooden diffuser plate, by
The closed structure of inside and outside height can not be reached in wooden diffuser plate, there is cavity to form resonance, so wooden diffuser plate has
Effect diffusion frequency narrow range, the cost that next wooden diffuser plate will make shape is higher, it is also difficult to real according to Two-Dimensional Quadratic
Remainder is theoretical next moulding.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope of this specification record is all considered to be.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more specific and detailed,
But therefore can not be interpreted as the limitation to the utility model the scope of the claims.It should be pointed out that common for this area
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
