Description

Indoor audio-visual environment adjusting wall material structure

Technical Field

The utility model relates to an indoor environmental protection functional structure technical field, concretely relates to pottery sand diatomaceous earth wall structure that indoor audio-visual environment adjusted.

Background

With the acceleration of urbanization, urban noise and light pollution have long become a public nuisance in urban environments. In addition, with the continuous improvement of living standard of people, people put forward higher and higher requirements for living environment. How to create more comfortable indoor life and audio-visual environment for people has become one of the hot points of concern in the fields of engineering construction and environment-friendly building materials.

In the prior art, in order to obtain good indoor audio-visual effect, besides good audio-visual playing equipment, a good audio-visual environment is also needed, and if the acoustic and optical conditions of a living room and a room are poor, the good and expensive equipment is not complemented, so that the indoor audio-visual environment needs to be modified.

At present, the indoor space which needs special acoustic and optical treatment is more and more common, including movie theaters, music halls, museums, exhibition halls, libraries, auditoria, galleries, auction halls, gymnasiums, report halls, multi-functional halls, hotel lobbies, hospitals, shopping malls, schools, musical instrument rooms, conference rooms, studios, recording rooms, KTV rooms, bars, industrial plants, machine rooms, home audiovisual rooms (video and audio rooms), and the like. These place that require higher and high-grade fitment to acoustic environment, optical environment all need carry out special reconnaissance, design and construction at present to and use and inhale special components such as sound decorative board, sound cotton of inhaling, but its design, construction requirement are complicated, and are with high costs, are unfavorable for using widely by a large scale, cause fire control safety, indoor air pollution and breed bacterium bugs scheduling problem moreover easily.

For indoor acoustic treatment, theoretically, although any material can absorb and reflect sound, the degree of absorption and reflection varies greatly. The sound absorption coefficient is the percentage of energy absorbed when sound waves are incident on and reflected from the surface of an object, and is represented by a (a is 0.0 to 1.0). The sound absorption capacity of a material is generally expressed by the arithmetic mean (average sound absorption number) of sound absorption coefficients at six octave center frequencies of 125, 250, 500, 1000, 2000 and 4000 HZ. Materials having an average sound absorption coefficient greater than 0.2 for the conventional six frequencies are generally listed as sound absorbing materials. Sound originates from the vibration of an object, which causes the vibration of the adjacent air to form sound waves, which propagate in the air medium all around. When sound is transmitted to the surface of the member material, a portion of the sound energy is reflected, a portion penetrates the material, and a portion of the sound energy is converted to heat energy by friction with the surrounding medium due to vibration of the member material or the sound propagating therein, and the sound energy is lost, i.e., the sound is absorbed by the material. Therefore, the sound absorption material is mostly loose and porous material, the sound absorption mechanism is that sound waves go deep into the pores of the material, the pores are mostly open pores with mutually communicated inner parts, and the sound absorption material is subjected to air molecule friction and viscous resistance and makes fine fibers perform mechanical vibration, so that sound energy is converted into heat energy. The improvement of the indoor sound field needs to consider not only the sound absorption effect but also the sound reflection and scattering so as to achieve the effect of the indoor sound field with clear sound and accurate positioning.

In the prior art, people often pay attention to processing and improving acoustic environments in places such as movie theaters, home video rooms, concert halls, studios, high-end houses and the like, and neglect comprehensive processing and improving of optical, temperature, humidity and other factors influencing audio and video effects and human body feeling. When the aspects are respectively treated and improved, the measurement, analysis, design, construction and acceptance are usually required to be respectively carried out, and different devices, materials, components and constructors are usually required to be used and construction is carried out for multiple times, so that the complexity of the measurement, the materials, the devices, the design and the construction is greatly increased, the cost is high, and the large-area popularization and application are not facilitated.

The diatomite wall material in the prior art, like the diatomite wall material disclosed in the chinese utility model patent 201110216947.2, is composed of diatomite: 20-40%, shell powder: 20-48% of diatomite ceramic sand: 10-25% of walnut shell particles: 5-10%, zeolite powder: 10-25%, bentonite: 1-8% and bamboo powder: 1-5%, seaweed gel: 0.5-3%, cellulose ether: 0.1-0.4 percent of diatomite ceramic sand with the grain diameter below 0.5mm, the utility model can greatly improve the heat preservation, heat insulation, moisture-proof and fireproof effects of the diatomite wall material, and achieve the effects of no volatilization, zero emission, zero pollution, meeting the requirements of circular economy and low carbon and environmental protection. It does not take into account and has an indoor acoustic, optical conditioning effect.

In the prior art, the basic requirements of indoor audio-visual spaces such as home theaters and movie theaters on the environment are 'black, empty and still'. The term "empty" means that other parts except necessary articles and seats are not placed in the room as much as possible, so that the clear space of the room can be enlarged under the condition of limited room volume, a large sound field can be created conveniently, and the sight of an observer can not be disturbed. "quiet" means that the invasion of various outdoor sounds or noises is isolated as much as possible, and meanwhile, irrelevant sounds cannot occur indoors, so as to avoid interfering the playback effect and ensure that the viewers enjoy the movies with full attention. The "null" and "quiet" are primarily for listening environments, while the "black" is for lighting environments. The dark environment is advantageous for reproducing the detail and vivid color of the image in low brightness conditions. If the indoor environment is too bright, the brightness and color saturation of the colors have to be adjusted greatly, which has a certain influence on the definition and contrast of the projected image, and the image loses the layering sense and expressive force. Therefore, the indoor lighting must also be designed and adjusted properly.

The existing indoor audio-visual environment adjusting construction needs to be designed, constructed and tested for many times to achieve the required environment adjusting effect, and the existing audio-visual environment adjusting construction also has the problem of indoor environment pollution caused by the fact that products such as soft packages, foams and organic coatings are adopted in a large amount.

For audiences, the temperature and the humidity of the indoor audio-visual environment are also important aspects influencing the experience effect, and the more concentrated and better audio-visual experience can be obtained under the relatively comfortable environment. However, in the prior art, these are all regulated independently and lack effective integration.

According to the results of the prior studies, early reflected sound with late direct sound less than 1ms in a room can significantly interfere with direct sound, making the sound more turbid, and thus affecting sound localization. Early reflected sound between 1-30 ms interferes less with the direct sound, and together with the direct sound, it helps to enhance loudness, but may change the timbre of the direct sound. For reflected sounds after 30ms, the human ear usually thinks it is reverberant. Therefore, the utility model discloses carrying out position, size and the texture design and the construction of plane of reflection, carrying out materials, texture structure, position, area etc. comprehensive consideration that adopt, make acoustics such as indoor sound absorption, diffusion, sound insulation handle, avoid too much reverberation can reduce the definition and the continuity of sound, influence playback sound effect.

At present, consumers mostly use a living room as a video and audio room, and more rooms can be independently used as the video and audio rooms. The room clearance area of the audio-visual room is more than 10 square, and the arrangement and the viewing distance of the equipment are reasonably distributed; the height of the room is not less than 2.8m and not more than 4 m; because the ceiling also can reflect sound, too high space because the sound arrival time of reflection is long, produces the unsafe problem of location easily, the utility model discloses also need carry out the processing of pertinence, through setting up specific plane of reflection or action face, adjust.

In the prior art, the audio-visual room is preferably rectangular and the ratio of the length, width and height of the room conforms to the golden section rule, such as 1: 1.25: 1.6, 1: 1.6: 2.5 or 1: 2.5: 3.2. However, this standard is often difficult to achieve in reality, so, adopt the utility model discloses, the accessible sets up the mode of wall body local area reflecting surface or action face, reforms the length, width and height ratio of seeing and hearing room into ideal situation.

The utility model discloses can be used to the processing to each indoor wall, smallpox. Can adopt the utility model discloses a material is under construction, is formed the stratum basale on whole wall body earlier, again influences the local area of audio frequency and video effect, sets up top layer and unsmooth texture. At present, the four walls of the wall body are mostly cement wall surfaces or brick walls, and the wall body has strong reflection to high, medium and low frequencies, especially to high frequencies. Therefore, sound absorption at a proper ratio and location becomes a primary task. But the sound absorption ratio cannot be too large, so that the layering sense and the rich sense of the sound are not influenced.

The utility model discloses can carry out the specific processing of pertinence to preceding, back, left and right four sides wall. For the left and right side walls, reflection surfaces are mainly provided for absorbing the first reflected sound emitted from the horn. The situation that positioning is not clear due to too many first-time reflected sounds and the sound sounds too loud is avoided; in this case, it is necessary to provide a strong adjustment reflecting surface at a position directly opposite to the horn and at a position intermediate between the horn and the auditorium to absorb sound. It is not necessary to make the entire wall surface a reflecting surface. The area of the reflection surface for this purpose is typically 1 to 1.5m wide, and the height of the entire wall surface 2/3 is high.

And (3) treating the horn rear wall body: the rear wall of the loudspeaker needs to be firm and hard, so that low frequency cannot be absorbed, and the power of the amplifier is doubled. A local reflecting surface of 1mX1m is generally made on the rear wall of the loudspeaker, and a weak adjusting reflecting surface is generally made, so that sound positioning is accurate and the sound level is full.

And (3) processing the horn rear wall corner wall body: any corner is the place with the strongest standing wave, and the left and right walls of the corner are respectively made into a local reflection surface of 0.5mX1m, and are generally made into a middle adjustment reflection surface to absorb redundant reflection sound.

And (3) processing a rear wall: the wall needs to absorb sound and also needs to diffuse. The suction is afraid of being too close to the rear wall and the reflected sound is too strong; diffusion is used because it makes the sound more natural because it is farther from the back wall. Generally, the whole rear wall is made into a low-adjustment reflecting surface, so that redundant reflected sound is absorbed, other reflected sound and mixed sound are diffused to the position of an auditorium, and the effects of absorption and diffusion are achieved.

And (3) ceiling treatment: generally, the ceiling also needs sound absorption and diffusion, and the whole rear wall is generally made into a low-adjustment reflecting surface or a weak-adjustment reflecting surface, so that the sound is best.

Wall surface treatment of compensatory treatment zones: if one side is a smooth cement wall and the other side is large cabinet furniture, a strong adjustment or medium adjustment reflecting surface is arranged at a position corresponding to one side of the cement wall to perform acoustic compensation processing, so that the acoustic performance of the two sides of the main sound box is as close to symmetry as possible. For example, a window, a door, etc. on one side, it is also necessary to provide a compensatory reflecting surface at a corresponding relative position to effectively reduce partially reflected sound and improve the clarity of sound, thereby improving the listening effect.

When the audio-visual indoor furnishing furniture of the utility model is adopted, the symmetrical shape is not taken as much as possible so as to prevent sound dyeing; otherwise, the sound-absorbing reflecting surface should be provided at the corresponding opposite position.
