Problems solved by technology

Therefore, it is often necessary to set up a soundproof room in places with quiet requirements. The traditional soundproof room can only install or spray sound-absorbing materials on the walls, which cannot limit the sound transmission in all directions, and the sound insulation effect is poor.

Abstract

The invention particularly discloses a sound insulation device. The sound insulation device comprises an upper base plate, a side base plate and a lower base plate. A sound insulation top plate is arranged on the inner side of the upper base plate, and a sound insulation side plate is arranged on the inner side of the side base plate. A sound insulation bottom plate is arranged on the inner side of the lower base plate. A sealed space is formed by the sound insulation top plate, the sound insulation side plate and the sound insulation bottom plate. A first keel is mounted on the outer side face of the sound insulation top plate. A first damping device is arranged between the first keel and the upper base plate. A second keel is mounted on the outer side face of the sound insulation side plate. A second damping device is arranged between the second keel and the side base plate. Damping bricks are arranged between the lower base plate and the sound insulation bottom plate. The sound insulation device is reasonable in design, good in sound insulation effect and capable of weakening the intensity of sound spreading along different media and different directions in an all-dimensional manner.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a sound insulation device. Background technique [0002] Most of the residents in the city now live in high-rise buildings, which are very concentrated. In addition, in order to reduce the load-bearing of the buildings, the sound insulation components of the current high-rise buildings are made of various lightweight materials, and the sound insulation performance is poor. If a resident plays a musical instrument in the house, the sound from the musical instrument will often affect the rest of the surrounding neighbors. Therefore, it is often necessary to set up a soundproof room in places where there is a need for quietness. The traditional soundproof room can only install or spray sound-absorbing materials on the walls, which cannot limit the sound transmission in all directions, and the soundproof effect is poor. [0003] For this reason, we propose a kind of sound...
