Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: a sound-insulating porous brick, comprising: a brick 1, a positioning block 2, a positioning groove 3, a corrugated groove 4, a plywood 5, a hole body 6, a sound-absorbing block 7, rock wool 701, urea-formaldehyde foam plastic 702, an inorganic fiber layer 703, a sound-insulating layer 8, an organic fiber layer 801, hemp cotton felt 802, glass wool 803 and a plastic film 9;

[0028] First, as attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown in the figure, a brick 1 and another brick 1 are combined together, so that the positioning block 2 above the plywood 5 is aligned with the plywood 5 fixed on the outside of the other brick 1, and the positioning blocks 2 fixed at equal intervals and the positioning grooves 3 distributed at equal intervals are connected by a slot, and the positioning blocks 2 and the positioning grooves 3 are arranged one by one, which can effectively limit the position and ensure stability. Cement is applied between the bricks 1 and the bricks 1, and the corrugated grooves 4 on the left and right sides of the plywood 5 increase the contact area between the bricks 1 and the cement, and the corrugated grooves 4 distributed at equal intervals increase the stability of the connection between the bricks 1 and the bricks 1;

[0029] As attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 6 As shown in , the brick 1 is provided with a hole body 6 in an array, and sound-absorbing blocks 7 are symmetrically arranged in the hole body 6. The array-distributed sound-absorbing blocks 7 increase the sound-absorbing area and edge effect, thereby improving the sound-absorbing effect. Since the sound-absorbing blocks 7 are composed of a combination of rock wool 701, urea-formaldehyde foam plastic 702, and inorganic fiber layer 703, the rock wool 701, urea-formaldehyde foam plastic 702, and inorganic fiber layer 703 contain a large number of uniformly distributed micropores and gaps, so that sound waves can effectively enter the rock wool 701, urea-formaldehyde foam plastic 702, and inorganic fiber layer 703, thereby increasing the reflection of sound waves.

Since the sound insulation layer 8 is composed of an organic fiber layer 801, a linen cotton felt 802 and a glass wool 803, the organic fiber layer 801, the linen cotton felt 802 and the glass wool 803 act as a resonant sound absorption structure. A plastic film 9 is fixed on the outside of the sound insulation layer 8 to increase the absorption of medium and high frequency sound waves. A plywood 5 is fixed on the outside of the plastic film 9 to increase the low-frequency sound absorption capacity.
