Method for reducing indoor acoustic noise

Abstract

The invention belongs to the technical field of environment protection, and in particular relates to a method for reducing indoor acoustic noise. Acoustic equipment adopted by the method comprises anacoustic equipment body, a first protection mechanism, a support mechanism, an installation mechanism, a second protection mechanism, a guiding rail, a clamping mechanism and a loudspeaker. Accordingto the method, the acoustic equipment is effectively damped and protected via clamping blocks on two sides of the acoustic equipment and a rubber pad at the bottom of the acoustic equipment, a whole desk is prevented from being driven to vibrate by the acoustic equipment when in playing, and the noise is reduced; a second fixing strop can rotate around a central column, so that second protective cloth can cover the outside of the loudspeaker, dustproof protection can be performed on the loudspeaker, shielding protection also can be further performed via the first protection mechanism, dust iseffectively prevented from entering the acoustic equipment, first protective cloth and the second protective cloth can be wound in a reel when not in use, the operation is simple and convenient, and the occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a method for reducing indoor acoustic noise. Background technique [0002] The harm of noise to the human body is systemic, which can not only cause changes in the auditory system, but also affect the non-auditory system. The early stages of these effects are mainly physiological changes, and long-term exposure to relatively strong noise can cause pathological changes. Many families will have audio-visual equipment, which will also produce noise pollution; used to play the sound of the TV, so that the sound transmission effect is better, the sound is louder, the speaker is the sound output device, speaker, subwoofer, etc.; a speaker includes High, low and medium speakers. [0003] When the speaker is playing sound, the vibration of the speaker will drive the entire cabinet to vibrate, and this vibration will spread to the table, resulting in noise. T...

AI Technical Summary

Problems solved by technology

[0003] When the speaker is playing sound, the vibration of the speaker will drive the entire box to vibrate, and this vibration will spread to the table, resulting in noise. The speaker is easy to enter dust during storage, and the dust will damage the components inside the speaker. , affecting its service life; most speakers are placed in combination with a TV, but the sound effect will be the best when the TV and the speaker are at a suitable installation distance
