Abstract
The purpose of this utility model is to propose a kind of preferable sound insulation antitheft door of soundproof effect.Sound insulation antitheft door of the present utility model includes the filler in door body and door body, and the surface of filler and the medial surface of door body are in close contact；The filler is made up of skeleton and the foaming layer being attached on skeleton, and the scattered line of sound panel of the skeleton by middle part and some umbrellas positioned at sound panel both sides is constituted, and less one end of diameter of the scattered line is fixedly connected with sound panel；The foaming layer is attached on sound panel, and is filled in the gap in scattered line and between scattered line and sound panel.Sound insulation antitheft door of the present utility model in filler by setting up the skeleton with acoustics sound insulation, scattered audio fruit so that the sound insulation value of antitheft door is greatly enhanced, and cost is low, be easy to manufacture, with good commercial promise.
Description
Technical field
The utility model belongs to antitheft door technical field, and in particular to a kind of sound insulation antitheft door.
Background technology
Antitheft door is in addition to antitheft purposes, and its excellent sound insulation value is also one of the reason for its is very popular.At present
The sound insulation of many antitheft doors is the simple packing material using in door body, such as saying rubber and plastic mixed plate, cellular board, not
The structure of its inside is improved using the principle of acoustics, accordingly, it can be said that the sound insulation value of antitheft door also has larger carry
Rise leeway.
The content of the invention
The purpose of this utility model is to propose a kind of preferable sound insulation antitheft door of soundproof effect.
Sound insulation antitheft door of the present utility model includes the filler in door body and door body, the surface of filler and door body it is interior
Side is in close contact；The filler is made up of skeleton and the foaming layer that is attached on skeleton, the skeleton by middle part sound insulation
The scattered line of plate and some umbrellas positioned at sound panel both sides is constituted, and less one end of diameter of the scattered line is consolidated with sound panel
Fixed connection；The foaming layer is attached on sound panel, and is filled in the gap in scattered line and between scattered line and sound panel
It is interior.
The sound insulation principle of above-mentioned antitheft door is as follows：
When sound wave passes through door body and touches filler, part energy is absorbed and consumes by foaming layer first, remaining
Sound wave pass through foaming layer after, can be obstructed by the scattered line of umbrella and produce reflection, acoustic wave segment is done by the back wave of same frequency
Counteracting is related to, meanwhile, sound panel also can play iris action to sound wave.More it is essential that being passed through through the sound wave of sound panel
When crossing the scattered line of opposite side, due to dissipate line acoustic resistance it is different from foaming layer, therefore acoustic wave segment can along scattered line sheet
Body direction is propagated, and changes original direction so that the energy of sound wave is more scattered, and sound that adjacent scattered line is propagated from
Ripple also occurs that interference is offset, so as to will further reduce the sound intensity.
For the ear of people, the irregular noise such as white noise is easily ignored, and the noise of single-frequency can draw
Attention especially is played, for this point, the diameter difference of the scattered line on sound panel same side is located in the utility model, with
Make the sound wave of reflection more mixed and disorderly, the noise of single-frequency is reduced, so as to reduce susceptibility of the people to the noise.
Further, the scattered line position positioned at sound panel both sides interlocks, to avoid sound wave from dissipating line directly through both sides.
Specifically, the sound panel is cellular board, and the scattered line is made up of plastics, and scattered line is pasted on sound panel
On；The foaming layer is made up of polyurethane foam material.Above-mentioned sound panel, foaming layer all have certain absorption, sound insulation in itself
Function, and the scattered line that plastics are made is easy to manufacture, cost is low, and the combination of foaming layer is more consolidated.
Sound insulation antitheft door of the present utility model by the way that the skeleton of audio fruit is set up with acoustics sound insulation, dissipated in filler,
So that the sound insulation value of antitheft door is greatly enhanced, and cost is low, be easy to manufacture, with good commercial promise.
Brief description of the drawings
Fig. 1 is the sectional view of sound insulation antitheft door of the present utility model.
Accompanying drawing is indicated：1st, door body；2nd, sound panel；3rd, line is dissipated；4th, foaming layer.
Embodiment
Below against accompanying drawing, by the description to embodiment, to embodiment of the present utility model as involved by
The shape of each component, construction, the mutual alignment between each several part and annexation, the effect of each several part and operation principle etc. make
It is further to describe in detail.
Embodiment 1：
As illustrated, the sound insulation antitheft door of the present embodiment includes the filler in door body 1 and door body 1, the surface of filler
It is in close contact with the medial surface of door body 1；The filler is made up of skeleton and the foaming layer 4 being attached on skeleton, the skeleton
It is made up of the scattered line 3 of the sound panel 2 at middle part and some umbrellas positioned at the both sides of sound panel 2, the diameter of the scattered line 3 is smaller
One end be fixedly connected with sound panel 2, and the diameter of the scattered line 3 on the same side of sound panel 2 is different（Refer in particular to dissipate line
3 are relatively large in diameter the diameter of the outer most edge at end）；The foaming layer is attached on sound panel 2, and is filled in scattered line 3 and scattered
In gap between line 3 and sound panel 2, so that skeleton, foaming layer 4 form an entirety.
In the present embodiment, sound panel 2 is cellular board, dissipates line 3 and is made up of plastics, dissipates line 3 and is pasted on sound panel 2
On；The foaming layer 4 is made up of polyurethane foam material.Above-mentioned sound panel 2, foaming layer 4 itself all have certain absorption, every
Sound function, and the scattered line 3 that plastics are made is easy to manufacture, cost is low, and the combination of foaming layer 4 is more consolidated.
The sound insulation principle of above-mentioned antitheft door is as follows：
When sound wave passes through door body 1 and touches filler, part energy is absorbed and consumes by foaming layer 4 first, it is residual
The sound wave deposited is passed through after foaming layer 4, can be obstructed by the scattered line 3 of umbrella and be produced reflection, acoustic wave segment is by the reflection of same frequency
Wave interference is offset, meanwhile, sound panel 2 also can play iris action to sound wave.More it is essential that through the sound of sound panel 2
Ripple is in the scattered line 3 by opposite side, because the acoustic resistance for dissipating line 3 is different from foaming layer 4, therefore acoustic wave segment can be along scattered
The body direction of line 3 is propagated, and changes original direction so that the energy of sound wave is more scattered, and adjacent scattered line 3 passes
Broadcast the sound wave come and also occur that interference is offset, so as to will further reduce the sound intensity.
After the noise of single-frequency is entered in door body 1, it can be reflected by scattered line 3 not of uniform size and form more mixed and disorderly
Noise, i.e., the noise of single-frequency is converted into the irregular white noise of frequency, so as to reduce sensitivity of the people to the noise
Degree.
In the present embodiment, the position of scattered line 3 positioned at the both sides of sound panel 2 interlocks, to avoid sound wave directly through both sides
Dissipate line.
