Abstract
The utility model provides a non -woven fabrics with inhale sound sound insulation effect, the non -woven fabrics lower floor that includes the non -woven fabrics upper strata and be located non -woven fabrics upper strata below be provided with a metal thin film layer between non -woven fabrics upper strata and the non -woven fabrics lower floor metal thin film layer's upper surface and lower surface are provided with a plurality of ascending protruding and decurrent swelling respectively, and are in it inhales the cotton layer of sound still to be provided with one on the plane region of metal thin film layer upper surface and lower surface respectively. The utility model discloses the special design of each level order reachs through the repetition test, it not simple stack, the cotton layer of sound is inhaled in this non -woven fabrics utilization, and produced vibrations form absorption and separation to sound, recycle the syllable -dividing effect that metallic film is good, reflect sound, thereby reach the effectual sound sound insulation effect of inhaling, each is ascending protruding and decurrent protruding then can disperse the sound wave that comes from in inside and the external environment condition to keep apart, so that other inhale the sound, sound -insulating structure plays a role better.
Description
Technical field
The utility model relates to a kind of non-woven fabrics, provides a kind of non-woven fabrics with sound-absorbing soundproof effect.
Background technology
Non-woven fabrics is not only commonly used by people in dressing, and is also widely used in indoor and outdoor decoration.Along with the growth in the living standard of people, the quickening of rhythm, dwelling environment is more and more noisy, and people want seeking peace and quiet in noisy surroundings.Therefore, the non-woven fabrics with noise elimination effect is valued by the people just more and more, has been widely used in the places such as concert hall, studio hall, cinema, conference room, karaoke chamber, can have completely cut off with external sound, keeps the privacy in room.But the soundproof effect of the noise elimination non-woven fabrics on market is unsatisfactory, do not reach and well eliminate the noise and erasure effect, people wish that a kind of novel noise elimination non-woven fabrics solves this problem.
Utility model content
Therefore, in order to solve prior art Problems existing, the utility model provides a kind of non-woven fabrics with sound-absorbing soundproof effect.
For solving this technical problem, the utility model takes following scheme: a kind of non-woven fabrics with sound-absorbing soundproof effect, comprise non-woven fabrics upper strata and be positioned at the non-woven fabrics lower floor below non-woven fabrics upper strata, a metal film layer is provided with between described non-woven fabrics upper strata and non-woven fabrics lower floor, be respectively arranged with a plurality of projection upwards and downward projection at the upper surface of described metal film layer and soffit, and be also respectively arranged with an acoustical cotton layer on the plane domain of described metal film layer upper surface and soffit.
Further improvement: the thickness of described metal film layer is 0.8-1.3mm.
Further improvement: each projection upwards and downward projection interval are arranged.
By adopting preceding solution, useful aspect of the present utility model is: the particular design of each level order of the utility model is through repetition test and draws, it not simple superposition, this sound insulation non-woven fabrics utilizes acoustical cotton layer form absorption to the vibrations that sound produces and intercept, the soundproof effect that recycling metallic film is good, sound is reflected, thus reach effective sound-absorbing soundproof effect, the sound wave come from inside and outside environment then can be carried out dispersion isolation by each projection upwards and downward projection, so that other sound-absorbings, sound-insulating structure plays a role better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 non-woven fabrics with sound-absorbing soundproof effect, the non-woven fabrics lower floor 2 comprising non-woven fabrics upper strata 1 and be positioned at below non-woven fabrics upper strata 1, a metal film layer 3 is provided with between described non-woven fabrics upper strata 1 and non-woven fabrics lower floor 2, the thickness of described metal film layer 3 is 0.9mm in the present embodiment, in actual production, as long as the thickness of this metal film layer 3 all can implement the purpose of this utility model between 0.8-1.3mm, a plurality of projection 4 upwards and downward projection 5 is respectively arranged with at the upper surface of described metal film layer 3 and soffit, each projection 4 upwards and downward projection 5 interval are arranged in the present embodiment, thus more fully can play the effect of carrying out disperseing isolation to sound wave, and an acoustical cotton layer 6 is also respectively arranged with on the plane domain of described metal film layer 3 upper surface and soffit.
By adopting preceding solution, useful aspect of the present utility model is: the particular design of each level order of the utility model is through repetition test and draws, it not simple superposition, this sound insulation non-woven fabrics utilizes acoustical cotton layer form absorption to the vibrations that sound produces and intercept, the soundproof effect that recycling metallic film is good, sound is reflected, thus reach effective sound-absorbing soundproof effect, the sound wave come from inside and outside environment then can be carried out dispersion isolation by each projection upwards and downward projection, so that other sound-absorbings, sound-insulating structure plays a role better.
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.
Claims (3)
1. one kind has the non-woven fabrics of sound-absorbing soundproof effect, comprise non-woven fabrics upper strata and be positioned at the non-woven fabrics lower floor below non-woven fabrics upper strata, it is characterized in that: between described non-woven fabrics upper strata and non-woven fabrics lower floor, be provided with a metal film layer, be respectively arranged with a plurality of projection upwards and downward projection at the upper surface of described metal film layer and soffit, and be also respectively arranged with an acoustical cotton layer on the plane domain of described metal film layer upper surface and soffit.
2. a kind of non-woven fabrics with sound-absorbing soundproof effect according to claim 1, is characterized in that: the thickness of described metal film layer is 0.8-1.3mm.
