In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. For convenience of description, the words "upper", "lower", "left" and "right" used herein refer to the same directions as the drawings, and do not limit the structure.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Embodiment, as shown in fig. 1, fig. 2, fig. 3 and fig. 4, the utility model provides a noise reduction laminate flooring, including face plywood 1, middle core plywood 2 and strengthening base plate 3, middle core plywood 2 includes the batten 21 of the mutual concatenation of polylith, is provided with the noise damping groove 22 on the batten 21, is provided with first noise damping hole 23 on the noise damping groove 22, strengthens being provided with on the base plate 3 with first noise damping hole 23 to the second noise damping hole 32 that corresponds, is provided with noise damping material in noise damping groove 22, first noise damping hole 23 and the second noise damping hole 32. On this basis, the utility model discloses the bottom surface at face plate 1 has set up netted structure groove 11, be provided with netted amortization pad 5 in netted structure groove 11, the side of lath 21 is provided with the through-hole parallel with amortization groove 22 direction, be provided with amortization pipe 6 in the through-hole, the side of amortization pipe 6 is provided with a plurality of and inhales the sound hole, amortization groove 22 includes upper amortization groove 221 and lower amortization groove 222 about lath longitudinal symmetry distribution, the top of reinforceing base plate 3 is provided with a plurality of strip archs 31 that correspond with lower amortization groove 22, second amortization hole 32 sets up on strip arch 31, be provided with damping deadening felt 7 between reinforceing base plate 3 and the lath 21, damping deadening felt 7 closely laminates with lath 21's bottom surface. The reticular structure grooves 11 serve as a hidden installation foundation of the reticular silencing pad, so that the integrity of the surface plate 1 can be ensured, and the reticular silencing pad 5 can exert the silencing capacity; the mesh-shaped sound-deadening pad 5 adopts a mesh-shaped structure, which is beneficial to collecting and acting on sound waves transmitted by the panel, so that a part of sound wave potential energy is converted into heat energy in the sound-deadening pad material before entering the middle core layer plate 2. Further, the utility model discloses adopted the structure of hush pipe 6 in middle core plywood 2, utilized hush pipe 6 to absorb the sound wave potential energy that middle core plywood 2 transmitted, made the striking frequency of sound wave in hush pipe 6 increase, consumed its potential energy and kinetic energy to cooperation amortization material reaches the purpose of amortization. Furthermore, the damping sound-proof felt 7 is made of high-purity fine iron powder as a raw material, and develops sound-proof materials for floors, walls and pipelines by applying the latest damping sound-proof technology, so that external noise can be effectively isolated. The damping deadening felt 7 is added between the middle core plate 2 and the strengthening base plate 3 to effectively improve the sound insulation capability of the product, and the silencing capability of the device is very favorable for reducing the transmission of high-frequency high-loudness noise or achieving the purpose of eliminating the noise.
