Embodiment Construction

[0008] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0009] See figure 1 , the present invention includes a sound-insulating board body 1 , concave blocks 2 are equally spaced on the inner wall of the sound-insulating board body 1 , and sound-absorbing sponge 3 is filled inside the sound-insulating board 1 and the bumps 2 .

[0010] After the noise source such as the motor emits noise, the sound wave propagates to the sound insulation panel 1, and the sound wave is weakened by multiple oscillations between the bumps 2 on the sound insulation panel body 1, and is absorbed by the sound-absorbing sponge 3 inside, effectively weakening the noise and preventing noise pollution.

Abstract

The invention provides an insulation board of a static sound box. The insulation board has good sound-absorbing property, and effectively weakens noises. The insulation board has an insulation board main body which is characterized in that the inner wall of the insulation board main body is provided with a bump.

Description

technical field [0001] The invention relates to the technical field of facilities for reducing noise, in particular to a sound insulation board for a mute box. Background technique [0002] Many motors, fans and other equipment are usually used in industrial production. The characteristics of these equipment will generate a lot of noise during operation, and workers who work in a noisy environment for a long time are likely to cause physical and mental damage. In view of the above problems, it is realized through research that the best way to deal with the excessive noise generated by specific sources such as motors and fans is to deal with the noise at the source, which is generally dealt with by adding an acoustic attenuation structure to the noise source, that is, for the motor , The fan is equipped with a silent speaker. However, the sound insulation effect of the mute box in the existing facilities is not ideal. Contents of the invention [0003] In view of the abov...
