Abstract
The utility model discloses a kind of sound-absorbing diffuser plate, it include sound-absorbing diffuser plate ontology, it is all machined with a plurality of dovetail groove in the front and back of sound-absorbing diffuser plate ontology, front dovetail groove and back side dovetail groove are interlaced, through-hole is formed at the interaction of front dovetail groove and back side dovetail groove, through-hole penetrates through front dovetail groove and back side dovetail groove, by the way that sound-absorbing slot is done stepped cross, the sound bass part passed over is set to be absorbed, and mid-high voice frequency sound is radiated through trapezoidal both sides inclined-plane, generate irreflexive effect, sound is spread by reflection around, obtain higher sound-absorbing and sound dispersion effect；Front and back all processes identical dovetail groove, the dovetail groove on two sides only need at same machining can, compare traditional structure abatvoix production efficiency higher.
Description
Technical field：
The utility model is related to Indoor environments to decorate Acoustic treatment technical field.
Background technology：
In all kinds of sound recordings and the Indoor environment decoration space of playback, such as：Recording studio, control room, audiovisual studio,
In the interior decorations such as home theater space, design and processing to indoor tone quality are essential.We are moulding sound field ring
When border, make sound dffusion uniformly, low-frequency band absorb entirely as one it is important build sound project, be conducive to the pure of sound quality
Only with raising.
It is equally known that compared with smooth reflecting surface, the diffuser of different structure can effectively avoid sound focusing.When
After slippery walls reflect, all acoustic energy will all reflect sound wave in the same direction, and reflection direction is fixed, and lead to sound focusing
The problem of occur.And when sound wave is after the diffuser surface reflection with different structure, acoustic energy will be reflected towards difference by dispersion
Direction, and have different phase differences.These random scatters sound for forming homogeneous energy can make human ear subjectivity generate one
Kind spatial impression, while being used in when medium-high frequency is spread can make sound more compliant, high frequency becomes more splendid.
But acoustic board structure on the market is as shown in Figure 1, the production of abatvoix is to dig square on plank decorative cover at present
The sound-absorbing slot 01 of shape processes a large amount of sound-absorption hole 02 in the bottom of plank, and sound-absorption hole 02 is counterbore, while the bottom of sound-absorption hole 02
It is communicated with rectangle sound-absorbing slot 01, when the abatvoix of this structure encounters the sound passed over, because 01 both sides of rectangle sound-absorbing slot are
Vertical side wall, sound enter after again can vertically reflect back, can not be spread, especially the sound of medium-high frequency section not by
Diffusion, causes medium-high frequency section sound excessively to be assembled, influences sound effect.In addition this traditional abatvoix is adding man-hour requirement first
Sound-absorbing slot 01 is processed, reprocesses sound-absorption hole 02, it is desirable that midway conversion equipment is processed, and processing efficiency is relatively low.
Invention content：
The shortcomings that the purpose of this utility model is to overcome the above-mentioned prior arts provides a kind of both absorbable all-bottom sound
Sound, and the sound-absorbing diffuser plate of diffusible intermediate frequency and high-frequency sound.
The goal of the invention of the utility model can be realized by technical solution below：A kind of sound-absorbing diffuser plate,
Include sound-absorbing diffuser plate ontology, is all machined with a plurality of dovetail groove in the front and back of sound-absorbing diffuser plate ontology, front is trapezoidal
Slot and back side dovetail groove are interlaced, and through-hole is formed at the interaction of front dovetail groove and back side dovetail groove, and through-hole penetrates through just
Face dovetail groove and back side dovetail groove.
Compared with prior art, the utility model has the beneficial effects that：By the way that sound-absorbing slot is done stepped cross, make to transmit
The sound bass part come is absorbed, and mid-high voice frequency sound is radiated through trapezoidal both sides inclined-plane, generates irreflexive effect, sound
By reflection diffusion around, higher sound-absorbing and sound dispersion effect are obtained；Front and back all processes identical dovetail groove,
The dovetail groove on two sides only need at same machining can, compare traditional structure abatvoix production efficiency higher.
Description of the drawings：
Fig. 1 is the three-dimensional structure diagram of prior art abatvoix；
Fig. 2 is the three-dimensional structure diagram of the utility model sound-absorbing diffuser plate.
Specific implementation mode：
The utility model is described in further detail below in conjunction with the accompanying drawings.
The sound-absorbing diffuser plate of the present embodiment includes sound-absorbing diffuser plate ontology 1, in the front of sound-absorbing diffuser plate ontology 1
A plurality of dovetail groove is all processed with the back side, front dovetail groove 2 and back side dovetail groove 3 are mutually perpendicular to interlock, 2 He of dovetail groove in front
Nature will form through-hole 4 during the interaction of back side dovetail groove 3 is in processing dovetail groove, and through-hole 4 penetrates through front dovetail groove 2
With back side dovetail groove 3.
The presence of a large amount of dovetail grooves is realized to the diffusing reflection effect of sound using the both sides inclined-plane a of dovetail groove, avoids sound
Sound focusing problem occurs after reflection, the sound of diffusion sounds more soft, steady.Low-frequency sound can via through holes 4 pass through the back of the body
Face dovetail groove 3 is absorbed subsequently into sound-absorbing sponge (not indicated in figure).
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation.Any technical person familiar with the field, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore every content without departing from technical solutions of the utility model, the shape according to the utility model
Equivalence changes made by shape, construction and principle should all be covered by the scope of protection of the utility model.
