[0001] This utility model relates to the field of noise reduction and sound insulation technology, specifically to an intelligent rehearsal room sound insulation device. Background Technology

[0002] Rehearsal rooms are places for people from all walks of life to rehearse. They are essential venues for various bands and artists before performances and require professional and complete equipment to ensure the quality of the performances that will follow.

[0003] The walls of existing rehearsal rooms are generally soundproof. During rehearsals, corresponding music needs to be played. The soundproof walls can reduce the noise inside the rehearsal room and prevent it from affecting the outside world. At the same time, it can also prevent the outside world from affecting the people inside the rehearsal room. However, the soundproof walls inside the rehearsal room are often fixed, and the soundproofing effect is constant. They cannot be intelligently adjusted according to the volume of the sound inside the rehearsal room, which has certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent rehearsal room soundproofing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an intelligent rehearsal room soundproofing device, comprising a rehearsal room, wherein the outer walls of the rehearsal room are provided with fixed soundproof walls, and an adjustable soundproof wall is installed at one end of the fixed soundproof wall near the rehearsal room. Several volume detectors are installed inside the rehearsal room. A cavity is formed inside the adjustable soundproof wall, and a positioning plate and a lifting plate are symmetrically installed inside the cavity. The lifting plate is connected to the top of the cavity via an electric push rod, and the positioning plate is fixedly connected to the bottom of the cavity. Several through slots are equidistantly arrayed on the surfaces of the lifting plate and the positioning plate. The volume detectors are electrically connected to the electric push rod via a control unit.

[0006] Preferably, a sound-absorbing wall is installed at the end of the adjustable soundproof wall closest to the rehearsal room.

[0007] Preferably, a second fixing plate and a first fixing plate are installed inside the rehearsal room on the left and right sides of the opening and closing door, respectively. The end of the second fixing plate facing the first fixing plate has a second sliding groove, and the end of the first fixing plate facing the second fixing plate has two symmetrical first sliding grooves. The first sliding grooves and the two second sliding grooves are arranged alternately.

[0008] Preferably, a second sound insulation plate is slidably connected inside the second sliding groove via an electric telescopic rod, and a first sound insulation plate is slidably connected inside both first sliding grooves via an electric telescopic rod.

[0009] Preferably, the cavity is equipped with a plurality of fixed guide rails arranged in an equidistant array, and the positioning plate and the lifting plate are each provided with a plurality of sliding grooves at equal intervals at the end facing the fixed guide rails, and the sliding grooves are slidably connected to the fixed guide rails.

[0010] Preferably, the fixed soundproof wall is made of a combination of soundproof board, concrete board and wood board, and the adjustable soundproof wall is made of metal soundproof board.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This intelligent rehearsal room soundproofing device uses several volume detectors installed inside the rehearsal room. These detectors record and transmit the sound levels to the control unit. The control unit then controls an electric push rod based on a set threshold. When the sound level is below the threshold, the electric push rod causes the lifting plate to align with the positioning plate. At this point, several through-slots on the surfaces of the lifting and positioning plates overlap, resulting in weak soundproofing. When the sound level is above the threshold, the electric push rod moves the lifting plate, causing the through-slots on the surfaces of the lifting and positioning plates to intersect until the through-slots are completely closed, achieving optimal soundproofing. By intelligently controlling the electric push rod through the control unit, which in turn moves the lifting plate, the soundproofing effect inside the soundproof wall is intelligently adjusted, making it more versatile.

[0013] 2. This intelligent rehearsal room soundproofing device uses a first fixed plate and a second fixed plate at the rehearsal room door. When the sound inside the rehearsal room exceeds a fixed threshold, the first soundproofing plate inside the first fixed plate and the second soundproofing plate inside the second fixed plate will move towards each other until they intersect. The first soundproofing plate and the second soundproofing plate will seal the door, thereby enhancing the soundproofing effect inside the rehearsal room. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] like Figures 1 to 4As shown, the intelligent rehearsal room soundproofing device in this embodiment includes a rehearsal room 1. The outer walls of the rehearsal room 1 are all equipped with fixed soundproof walls 9, which provide the main support and a certain degree of soundproofing. An adjustable soundproof wall 16 is installed at one end of the fixed soundproof wall 9 near the rehearsal room 1. The adjustable soundproof wall 16 can automatically adjust the internal soundproofing effect to adapt to the sound level inside the rehearsal room 1. Several volume detectors 2 are installed inside the rehearsal room 1, representing mature existing technology. These volume detectors 2 are distributed along the walls inside the rehearsal room 1 and can monitor the sound level inside the rehearsal room 1 at all times. A cavity 11 is formed inside the adjustable soundproof wall 16. A positioning plate 13 and a lifting plate 12 are symmetrically installed inside the cavity 11. The lifting plate 12 is connected to the top of the cavity 11 via an electric push rod 17. The electric push rod 17 is located at the adjustment... Inside the soundproof wall 16, the lifting plate 12 can be moved up and down within a certain range. The positioning plate 13 is fixedly connected to the bottom of the cavity 11. Several through slots 14 are equidistantly arrayed on the surfaces of the lifting plate 12 and the positioning plate 13. The volume detector 2 and the electric push rod 17 are electrically connected through a control unit. The control unit controls the electric push rod 17 according to the set threshold. When the sound level is lower than the threshold, the electric push rod 17 will drive the lifting plate 12 to overlap with the positioning plate 13. At this time, the multiple through slots 14 on the surfaces of the lifting plate 12 and the positioning plate 13 will overlap, and the sound insulation effect is weak. When the sound level is higher than the threshold, the electric push rod 17 will drive the lifting plate 12 to move, so that the through slots 14 on the surfaces of the lifting plate 12 and the positioning plate 13 will intersect until the through slots 14 are completely closed, and the sound insulation effect is optimal.

[0022] Specifically, a sound-absorbing wall 10 is installed at the end of the soundproof wall 16 closest to the rehearsal room 1. The sound-absorbing wall 10 is made of sound-absorbing cotton, which has a porous structure inside, allowing sound to rub against each other and be converted into heat energy, thus achieving sound absorption.

[0023] Furthermore, inside rehearsal room 1, on the left and right sides of the opening and closing door, a second fixed plate 6 and a first fixed plate 3 are respectively installed. The end of the second fixed plate 6 facing the first fixed plate 3 has a second sliding groove 7, and the end of the first fixed plate 3 facing the second fixed plate 6 has two symmetrical first sliding grooves 4. The first sliding grooves 4 and the two second sliding grooves 7 are staggered. The interior of the second sliding groove 7 is slidably connected to a second sound insulation plate 8, and the interior of each of the two first sliding grooves 4 is slidably connected to a first sound insulation plate 5. By installing the first fixed plate 3 and the second fixed plate 6 at the door of rehearsal room 1, when the sound inside rehearsal room 1 exceeds a fixed threshold, the first sound insulation plate 5 inside the first fixed plate 3 and the second sound insulation plate 8 inside the second fixed plate 6 will move towards each other via an electric telescopic plate. The electric telescopic plate is existing technology, connected to a power source to move until they are staggered. The first sound insulation plate 5 and the second sound insulation plate 8 seal the door, thereby enhancing the sound insulation effect inside rehearsal room 1.

[0024] Furthermore, several fixed guide rails 15 are installed in an equidistant array inside the cavity 11. Several sliding grooves are equally spaced on the end of the positioning plate 13 and the lifting plate 12 facing the fixed guide rails 15. The sliding grooves are slidably connected to the fixed guide rails 15. By setting multiple fixed guide rails 15, and the fixed guide rails 15 are slidably connected to the positioning plate 13 and the lifting plate 12 through the sliding grooves, the movement of the lifting plate 12 can be guided and limited.

[0025] Furthermore, the fixed soundproof wall 9 is made of a combination of soundproofing panels, concrete panels, and wooden panels. The concrete panels are located on the outermost side of the fixed soundproof wall 9, providing support. The wooden panels are located on the innermost side of the fixed soundproof wall 9 and are connected to the adjustable soundproof wall 16. The soundproofing panels are located in the middle and are made of damping soundproofing panels, providing a certain degree of sound insulation. The adjustable soundproof wall 16 is made of aluminum alloy soundproofing panels, which have higher strength and better stability. The lifting plate 12 and the positioning plate 13 are made of mineral wool soundproofing panels, which have advantages such as being non-combustible, fireproof, and heat-insulating. The porous structure inside helps with sound absorption.

[0026] The usage method of this embodiment is as follows: By installing multiple volume detectors 2 inside the rehearsal room 1, the volume detectors 2 will detect and record the sound level inside the rehearsal room 1 and transmit it to the control unit. The control unit will control the electric push rod 17 according to the set threshold. When the sound level is lower than the threshold, the electric push rod 17 will drive the lifting plate 12 to overlap with the positioning plate 13. At this time, the multiple through slots 14 on the surface of the lifting plate 12 and the positioning plate 13 will overlap, and the sound insulation effect is weak. When the sound level is higher than the threshold, the electric push rod 17 will drive the lifting plate 12 to move, so that the through slots 14 on the surface of the lifting plate 12 and the positioning plate 13 will intersect until the through slots 14 are completely closed. At this time, the sound insulation effect is optimal. By intelligently controlling the electric push rod 17 through the control unit, the electric push rod 17 drives the lifting plate 12 to move up and down, thereby intelligently changing and adjusting the sound insulation effect inside the soundproof wall 16, making it more versatile.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
