[0002] In the existing floor structure, once the neighbors, especially the upstairs residents, have a large knock and friction action, the vibration and noise generated in the upstairs room are easily transmitted to the downstairs through the wall panels, affecting the rest of the downstairs residents and affecting the safety of the neighbors. Serious disturbances in life, especially at night
The existing sound insulation structure used for floor slabs is only to lay sound insulation boards, but the existing sound insulation boards have poor sound insulation and shock isolation effects, and cannot effectively eliminate most of the noise and vibration generated upstairs, and will still have a large impact on the rest of the downstairs residents.

The invention discloses a floor noise reduction device. The floor noise reduction device comprises a metal framework and a noise reduction device body, wherein the metal framework comprises an upper metal framework body and a lower metal framework body, the noise reduction device body is located between the upper metal framework body and the lower metal framework body, and the noise reduction device body comprises a composite vibrating diaphragm, a first sound absorption layer and a gypsum layer which are sequentially arranged from top to bottom; the noise reduction device body further comprises a sound collection sensor arranged on the upper surface of the composite vibrating diaphragm, a controller connected with the sound collection sensor, and an electric ceramic vibrating sheet connected with the controller and attached to the lower surface of the composite vibrating diaphragm. The floor noise reduction device is ingenious in structural design, remarkable in noise reduction effect, economical and practical.
Description
technical field [0001] The invention relates to the technical field of building noise reduction equipment, in particular to a floor noise reduction device. Background technique [0002] In the existing floor structure, once the neighbors, especially the upstairs residents, have a large knock and friction action, the vibration and noise generated in the upstairs room are easily transmitted to the downstairs through the wall panels, affecting the rest of the downstairs residents and affecting the safety of the neighbors. Life brings serious disruptions, especially at night. The existing sound insulation structure used for floor slabs is only to lay sound insulation boards, but the existing sound insulation boards have poor sound insulation and shock isolation effects, and cannot effectively eliminate most of the noise and vibration generated upstairs, and will still have a large impact on the rest of the downstairs residents. Impact. Contents of the invention [0003] The ...
