The invention discloses a noise-reducing device for a generator. Supporting columns are arranged on the inner sides of a first cavity and a second cavity; an air inlet pipe and an air outlet pipe separately communicate to the left and right sides of the base; an air blower is mounted on the outer side of the air inlet pipe; the air outlet of the air blower communicates to the top of the air inletpipe through an air pipe; a generator placing base is connected to the inner bottom of the base through a shock absorbing piece; cone-shaped protruding rings are arranged on the inner sides of the airinlet pipe and the air outlet pipe; and a cable hole is formed through the outer side of the air inlet pipe. By extracting gas in the first and second cavities, the first and second cavities form a vacuum state, so that the sound isolating effect is better; by arranging the plurality of cone-shaped protruding rings, sound can be emitted and weakened effectively in the air outlet pipe, so that thenoise is lowered.
Description
technical field [0001] The invention relates to the technical field of noise reduction equipment, in particular to a generator noise reduction device. Background technique [0002] A chaotic, dissonant-sounding sound that varies in pitch and intensity. It is produced by the irregular vibration of the sounding body. From a physical point of view: noise is the sound made when the sounding body vibrates irregularly. Refers to noisy, harsh sound. From the perspective of environmental protection: all sounds that hinder people's normal rest, study and work, and sounds that interfere with the sounds that people want to listen to are all noise. Noise is a kind of sound that causes irritability or is too loud and endangers human health. Noise pollution mainly comes from transportation, vehicle horns, industrial noise, building construction, and social noise such as concert halls, tweeters, morning markets, and people talking loudly. [0003] When using a household generator, it w...
