Description
Technical field
The utility model relates to room door field, particularly a kind of Novel sound-proof door.
Background technology
Along with the development of the modern industry, environment pollution is also along with generation, and noise pollution is exactly the one of environment pollution, has become and has endangered greatly the mankind's one.Noise pollution and water pollutions, atmosphere pollution are regarded as three main Environmental Problems in world wide.Noise can cause various diseases, and noise, except damage hearing, also can cause other damages to person.That noise can cause is in a disturbed state of mind, be nervous, palpitating speed and blood pressure increase.Noise also can make the saliva of people, gastric secretion reduces, and hydrochloric acid in gastric juice reduces, thus easily suffers from gastric ulcer and duodenal ulcer.Some industrial noise investigation results are pointed out, the iron and steel of working under high noisy condition is individual and machine shop individual is higher than the individual circulating system incidence of disease under quiet condition.Under strong sound, hypertensive people is also many.Many people think, the noise in the life of 20th century causes one of cardiopathic reason.Work under noisy environment for a long time, also can cause obstacle to nervous function.Under laboratory condition, human experimentation proves, under noise effect, people's brain wave can change.Noise can cause the balance that cerebral cortex is excited and suppress, thus the exception reflected under causing condition.Some patients can cause intractable headache, neurasthenia and cranial nerve insufficient.Symptoms has much relations with the noise intensity contacted.Such as, when noise is at 80-85 decibel, often very emotional, feel fatigue, headache is many in temporo frontal region; During 95-120 decibel, the normal fore head passivity pain of operation individual, and with emotional, dyssomnias, dizziness, failure of memory; Noise not only causes otopathy when arriving by force 140-150 decibel, and generation is frightened and whole body nervous system tonicity increases.
Be a kind of effective means reducing noise pollution at indoor employing sound insulation materials, therefore, how developing a kind of Novel sound-proof door with superior acoustic effect is problem to be solved in the utility model.
Utility model content
Therefore, in order to the problems referred to above, the utility model provides a kind of Novel sound-proof door.
For solving this technical problem, the utility model takes following scheme: a kind of Novel sound-proof door, comprise door-plate, lower door-plate and middle stiffener and the decorative layer be coated on this on door-plate and lower door-plate external surface, and on described between door-plate and stiffener and be provided with puigging between door-plate and stiffener down, and between described upper door-plate and puigging and be provided with cavity between door-plate and puigging down, the external surface that described puigging is positioned at cavity is covered with arc protuberance, and described stiffener is composited by the sound absorbing layer of aluminium alloy plate and both sides thereof.
Further improvement: described upper door-plate is formed by aluminium alloys or the manufacture of wood-based plate material.
Further improvement: described lower door-plate is formed by aluminium alloys or the manufacture of wood-based plate material.
Further improvement: described puigging is stereotype.
Further improvement: described sound absorbing layer is acoustical cotton layer.
By adopting preceding solution, the beneficial effects of the utility model are: a kind of Novel sound-proof door described in the utility model adopts quadruple sound insulation to arrange, there is excellent soundproof effect, first described upper door-plate and lower door-plate form by aluminium alloys or the manufacture of wood-based plate material, due to this kind of densify, be difficult to absorb and reflect through acoustic energy and by force, the first sound insulation weighed can be formed and arrange; Secondly, the sound wave through described upper door-plate and lower door-plate can echo door-plate and puigging and in the lower cavity arranged between door-plate and puigging on described and cut down, and plays certain soundproof effect; In addition, because sound wave defers to refraction and the reflection law of light wave, therefore the external surface being positioned at cavity at described puigging is covered with arc protuberance, its surface is arranged in curved surface, be conducive to improving the reflection of the acoustic energy of sound wave on this puigging, reduce its transmission acoustic energy, improve the soundproof effect of this soundproof door; Finally, through the acoustical cotton layer of sound wave on stiffener of this puigging, again by absorption abatement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, the utility model embodiment discloses a kind of Novel sound-proof door, comprise door-plate 1, lower door-plate 2 and middle stiffener and the decorative layer 41 be coated on this on door-plate 1 and lower door-plate 2 external surface, 42, and puigging 51 is provided with between door-plate 1 and stiffener and between lower door-plate 2 and stiffener on described, 52, and be provided with cavity 61 between described upper door-plate 1 and puigging 51 and between lower door-plate 2 and puigging 52, 62, the external surface that described puigging 51 is positioned at cavity 61 is covered with arc protuberance, the external surface that described puigging 52 is positioned at cavity 62 is covered with arc protuberance, described stiffener is by the sound absorbing layer 32 of aluminium alloy plate 31 and both sides thereof, 33 are composited.Described upper door-plate 1 is formed by aluminum alloy material manufacture.Described lower door-plate 2 is formed by aluminum alloy material manufacture.Described puigging 51,52 is stereotype.Described sound absorbing layer 31,32 is acoustical cotton layer.
The beneficial effects of the utility model are: a kind of Novel sound-proof door described in the utility model adopts quadruple sound insulation to arrange, there is excellent soundproof effect, first described upper door-plate 1 and lower door-plate 2 form by aluminum alloy material manufacture, due to this kind of densify, be difficult to absorb and reflect through acoustic energy and by force, the first sound insulation weighed can be formed and arrange; Secondly, the cavity 61 that the sound wave through described upper door-plate 1 and lower door-plate 2 can be arranged door-plate 1 and puigging 51 and between lower door-plate 2 and puigging 52 on described, echo in 62 abatement, plays certain soundproof effect; In addition, because sound wave defers to refraction and the reflection law of light wave, therefore at described puigging 51,52 are positioned at cavity 61, and the external surface in 62 is covered with arc protuberance, and its surface is arranged in curved surface, be conducive to improving sound wave at this puigging 51, reflection of the acoustic energy on 52, reduces its transmission acoustic energy, improves the soundproof effect of this soundproof door; Finally, through the acoustical cotton layer of sound wave on stiffener of this puigging 51,52, again by absorption abatement.
In sum, a kind of Novel sound-proof door described in the utility model is novel in design, and structure is simple, effectively can play the effect of sound insulation, noise reduction, have positive effect for the dwelling environment improving people.
Although specifically show in conjunction with preferred embodiment and describe the utility model; this technical scheme method and access of specific implementation is a lot; the above is only preferred embodiment of the present utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection domain of the present utility model.
