Technical Field
[0001] The utility model relates to the technical field of vibration reduction and noise reduction, in particular to a spring floating vibration reduction structure of a sound insulation cover. Background Art
[0002] With the acceleration of urbanization, people's living space is becoming increasingly dense, and noise disturbances caused by facilities such as range hoods and fans in office buildings, hotels, and shopping malls are frequent. A soundproof enclosure is a sound insulation device that uses a enclosure to cover the sound source inside and control the transmission of noise from the source. It is currently a conventional measure to reduce the impact of equipment noise. At present, when equipment uses soundproof enclosures to reduce noise, the resonance problem of the enclosure body excited by the equipment noise is often ignored. The vibration noise of the soundproof enclosure is transmitted through the ground and affects the space below, resulting in unsatisfactory noise reduction effect of the soundproof enclosure, and the noise nuisance problem still exists. It is now necessary to invent a technology to isolate the vibration noise of the soundproof enclosure structure to solve the above problems. Utility Model Content
