specific Embodiment 1
[0030] This embodiment is the wall structure embodiment of the music classroom.
[0031] The music classroom wall structure of present embodiment, as figure 1 shown. The wall structure of the music classroom has a first adhesive layer 2 , a straw layer 3 , a second adhesive layer 4 , a random grid wire layer 5 , and a protective layer 6 outside the cement layer 1 .
[0032] In order to verify the sound quality effect of the wall structure of the present invention, the following experiments were carried out:
[0033] First, compare the effects of adding straw layer 3 and not adding straw layer 3: After adding straw layer 3, the sound insulation effect of the wall is better; in addition, please invite 10 piano players, and they agree that adding straw layer 3 to the wall After that, the sound quality is fuller.
[0034] Second, compare the effect of adding random grid wire layer 5 and not adding random grid wire layer 5: test the low-frequency sound segment of 20-200 Hz that ...
specific Embodiment 2
[0035] This embodiment is the wall structure embodiment of the music classroom.
[0036] The music classroom wall structure of the present embodiment is further defined on the basis of the specific embodiment one:
[0037] The first adhesive layer 2 is a grid layer whose basic unit is a square;
[0038] The second adhesive layer 4 is a ring array layer; the ring is an inscribed circle of a square;
[0039] The protective layer 6 is a layer formed naturally after the cement slurry dries.
[0040] The shape design of the first bonding layer 2 and the second bonding layer 4, such as figure 2 As shown, this design can improve the sound effect. For this reason, the following experiments have been carried out. Experiment 1, the first adhesive layer 2 is designed as a rectangle, random graphics, and no graphics; the second adhesive layer 4 is the same Designed as a rectangle, irregular graphics, and no graphics; and let the graphics of the first adhesive layer 2 and the second ad...
specific Embodiment 3
[0042] This embodiment is the wall structure embodiment of the music classroom.
[0043] The music classroom wall structure of the present embodiment is further limited on the basis of the first or second specific embodiment: the production method of the straw layer 3 is as follows:
[0044] Step a, respectively pulverizing straw and cactus;
[0045] Step b, mixing straw, cactus, and salt according to the ratio of 1000:100:1;
[0046] Step c, the mixture obtained in step b is compressed, and the pressure is 3 atmospheres, and pressed into a thin plate with a thickness of 2mm;
[0047] Step d, engraving parallel grooves with a width of 1mm and a depth of 0.5mm on the thin plate obtained in step c, and the width between two adjacent grooves is 10mm;
[0048] Step e, bonding the two thin plates obtained in step d together in a direction in which the grooves are opposite and the directions are perpendicular.
[0049] The above processing method can ensure that the straw layer 3...
