Abstract
The purpose of this utility model is to propose a kind of soundproof door, and sound wave can be converted into other energy by this kind of soundproof door, so as to improve soundproof effect.Soundproof 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 by foaming layer and becomes scattered about the hollow ball in foaming layer and constitutes, and the hollow ball is built with sand-like thing.Soundproof door of the present utility model in door in addition to setting traditional foaming layer for sound insulation, the hollow ball of built-in sand-like thing is provided with also in foaming layer, so as to which the energy of acoustic wave segment to be converted into the vibration of sand-like thing, erasure effect is improved, so that door has good sound insulation value.
Description
Technical field
The utility model belongs to door and window manufacturing technology field, and in particular to a kind of soundproof door.
Background technology
Either common door or antitheft door, its soundproof effect are all to benefit from very much family concern.At present many doors every
Sound is the simple packing material using in door body, and such as saying rubber and plastic mixed plate, cellular board, the principle of acoustics is not utilized
Structure to its inside is improved, accordingly, it can be said that the sound insulation value of door also has larger lifting leeway.
The content of the invention
The purpose of this utility model is to propose a kind of soundproof door, and sound wave can be converted into other energy by this kind of soundproof door,
So as to improve soundproof effect.
Soundproof door of the present utility model includes the filler in door body and door body, the surface of filler and the medial surface of door body
It is in close contact；The filler is by foaming layer and becomes scattered about the hollow ball in foaming layer and constitutes, the hollow ball built with
Sand-like thing.
The sound insulation principle of above-mentioned soundproof 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 hollow ball and produce reflection, acoustic wave segment is supported by the reflection wave interference of same frequency
Disappear.More it is essential that into the sound wave of hollow ball sand-like thing can be driven to vibrate, so as to part energy is converted into sand-like
The small vibrations of thing, so as to will further reduce the sound intensity.As long as controlling the particle diameter of sand-like thing itself, quality, you can control
The local frequency of sand-like thing is made, sand-like thing can be targetedly used for the common noise frequency of use environment, so that
Improve sound insulation soundproof effect.
Sand-like thing friction, which is produced in noise, the hollow ball, when further, to avoid rotating is also equipped with liquid,
The sand-like thing is dipped in or is suspended in liquid.Movement of the liquid to sand-like thing is applied with certain resistance, door can be avoided to open
Sand-like thing quick movement during pass and produce noise.
Further, the liquid is thick liquid, and so sand-like thing will be suspended in thick liquid, without accumulating
In the bottom of liquid, so as to improve acoustic attenuation performance.
Further, it is the silencing noise that adapts to different frequency, the hollow ball has a plurality of specifications size, and same specification
Sand-like thing content in hollow ball is different, and the local frequency of so each hollow ball is different, and the hollow ball in whole door body is with regard to shape
Into wider spectral range, it can be eliminated the noise for the noise of multi-frequency.
Soundproof door of the present utility model in door in addition to setting traditional foaming layer for sound insulation, also in foaming layer
There is provided the hollow ball of built-in sand-like thing, so that the energy of acoustic wave segment to be converted into the vibration of sand-like thing, improves noise reduction effect
Really, so that door has good sound insulation value.
Brief description of the drawings
Fig. 1 is the sectional view of soundproof door of the present utility model.
Accompanying drawing is indicated：1st, door body；2nd, foaming layer；3rd, hollow ball.
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 soundproof door of the present embodiment includes the filler in door body 1 and door body 1, the surface of filler and door
The medial surface of body 1 is in close contact；The filler is by foaming layer 2 and becomes scattered about the hollow ball 3 in foaming layer 2 and constitutes, described
Hollow ball 3 is suspended in thick liquid built with thick liquid and sand-like thing, sand-like thing.
Movement of the thick liquid to sand-like thing is applied with certain resistance, and sand-like thing during door switch can be avoided quickly to move
And produce noise.And sand-like thing is suspended in thick liquid, without being deposited in the bottom of liquid, so as to improve sound damping quality
Energy.In the present embodiment, sand-like thing is less than the 0.5mm grains of sand using particle diameter, and thick liquid uses polyaminoester emulsion, utilizes plastics
Sand-like thing, thick liquid are packaged in wherein by the hollow ball 3 being made, and hollow ball 3 is scattered when foaming layer is foamed put
It is placed in expanded material.
The sound insulation principle of above-mentioned soundproof door is as follows：
When sound wave passes through door body 1 and touches filler, part energy is absorbed and consumes by foaming layer 2 first, it is residual
The sound wave deposited is passed through after foaming layer 2, can be obstructed by hollow ball 3 and be produced reflection, acoustic wave segment is done by the back wave of same frequency
Relate to counteracting.More it is essential that into the sound wave of hollow ball 3 sand-like thing can be driven to vibrate, so that part energy be converted
For the small vibrations of sand-like thing, so as to will further reduce the sound intensity.As long as controlling the particle diameter of sand-like thing itself, quality,
I.e. can control sand-like thing local frequency, can for use environment common noise frequency come targetedly use it is sand-like
Thing, so as to improve sound insulation soundproof effect.
To adapt to the silencing noise of different frequency, the hollow ball has plurality of specifications size, and in the hollow ball of same specification
Sand-like thing content it is different, the local frequency of so each hollow ball is different, and the hollow ball in whole door body 1 is formed wider
Spectral range, can be eliminated the noise for the noise of multi-frequency.
