[0023] The utility model provides a combined sound-absorbing wall, such as Figure 1 、 Figure 3 、 Figure 4As shown, it includes a frame 1, which is composed of many components. The upper crossbeam 12, the lower crossbeam 14 and the left vertical beam 13, the right vertical beam 15, and the support beam 11 are bolted together through screw holes in the grooves 121, which greatly enhances the stability of the overall structure of the frame 1. The grooves 121 on the upper crossbeam 12 and the lower crossbeam 14 are set towards the back of the frame 1, which is conducive to installing various components on the wall. The first slide groove 161 on the first sound-absorbing strip 16 is used to connect with the second protrusion 322 of the first sound-absorbing panel 3, the first protrusion 171 on the second sound-absorbing strip 17 can be inserted into the third slide groove 324 of the first group of sound-absorbing devices 2, and the third protrusion 323 of the last group of sound-absorbing devices 2 can be inserted into the fourth sound-absorbing strip 19. There are multiple groups of sound-absorbing devices 2 inside the frame 1, and the multiple groups of sound-absorbing devices 2 are connected in sequence. The sound-absorbing devices 2 in the sound-absorbing wall are all connected by splicing components, which is simple and effective to install.

[0024] like Figure 2 As shown, the first sound-absorbing panel 3 is composed of a plurality of sound-absorbing materials. The polyester fiber sound-absorbing panel 31 not only has high sound absorption but also has a variety of colors. It is most suitable for being set in the outermost layer. The porous wood sound-absorbing panel 32 not only has a good sound absorption effect, but also has a higher strength than other sound-absorbing materials. It is suitable for setting splicing components on its edge. The wood grain veneer 321 is arranged on both sides of the porous wood sound-absorbing panel 32 to facilitate bonding with other sound-absorbing materials. The fiber cement board 33 has a good sound insulation effect and good thermal insulation performance. It is suitable for bonding with the positioning wooden board 34 in the innermost part. The positioning wooden board 34 is arranged for splicing with the support beam 11, which can play a positioning role so that the sound-absorbing device 2 is not easy to shake left and right.

[0025] Working principle: First, vertically fit the left vertical beam 13, the right vertical beam 15 and the support beam 11 on the wall, with the opening of the support beam 11 facing downwards. Then, combine the groove 121 of the upper crossbeam 12 with the left vertical beam 13, the right vertical beam 15 and one end of the support beam 11, and then insert a bolt into the groove 121 to fix it. Fit the first sound-absorbing strip 16 to the upper crossbeam 12, the second sound-absorbing strip 17 to the left vertical beam 13, and the fourth sound-absorbing strip 19 to the upper part of the right vertical beam 15. Then, place the first sound-absorbing panel 3 on the leftmost support beam. In the empty space between the support beam 11 and the left vertical beam 13, slide it to the left so that its third slide groove 324 is connected to the first protrusion 171, and then slide it upward so that its second protrusion 322 is connected to the first slide groove 161. In this way, the first sound-absorbing panel 3 is in place, so that the receiving groove on the first sound-absorbing panel 3 covers the support beam 11, so that the receiving groove and the support beam 11 are snap-fitted, and then screws are used to penetrate the first sound-absorbing panel 3 to fix it on the support beam 11, and then the second sound-absorbing panel 4 is placed between the support beam 11 and the left vertical beam 13, and slide it to the left. The first cam 324 is connected to the first protrusion 171, and then the second cam 322 is connected to the fourth cam 325 of the first sound-absorbing panel 3. The first set of sound-absorbing devices 2 is installed. Next, all the sound-absorbing devices 2 except the two on the right are installed inside the frame 1 from left to right. The installation order of the two sound-absorbing devices 2 on the right side of the frame 1 is as follows: first, place one sound-absorbing device 2 from the lower right corner of the frame 1, move it upward along the second cam 192 to the top, and then install the last sound-absorbing device 2. The sound-absorbing device 2 is placed from the lower right corner of the frame 1 and moved horizontally to the left along the fourth slide groove 325 of the upper sound-absorbing device 2 to tightly connect with the adjacent sound-absorbing device 2. The fifth sound-absorbing strip 191 is then attached to the lower portion of the right vertical beam 15. The limiting groove 193 on the fifth sound-absorbing strip 191 covers the third protrusion 323 of the last sound-absorbing device 2 installed. Finally, the lower crossbeam 14 is fixedly connected to the left vertical beam 13, the right vertical beam 15, and the support beam 11 with bolts, and the third sound-absorbing strip 18 is adhered to the lower crossbeam 14.
