Laminated structure sound insulation device
The invention relates to the field of sound insulation equipment, and in particular, relates to a laminated structure sound insulation device. A composite damping sound insulation material layer, a hot melt adhesive layer, a rubber damping layer and a metal sound insulation layer are sequentially arranged in a stacked mode, and a cavity is formed in the hot melt adhesive layer. The composite damping sound insulation material layer, the hot melt adhesive layer, the rubber damping layer and the metal sound insulation layer which are stacked in sequence are arranged, wherein the composite dampingsound insulation material layer has a certain damping property; sound energy can be consumed in forms of shearing, stretching and the like; the hot melt adhesive layer mainly plays a role in connecting the composite damping sound insulation material layer and the rubber damping layer; however, the cavity formed in the hot melt adhesive layer can attenuate sound energy and weaken the resonance anastomosis effect, the rubber damping layer and the metal sound insulation layer form a constraint damping sound insulation structure, all the layers are matched with one another, resonance and criticalanastomosis frequency can be staggered, and thus the light and efficient sound insulation effect is achieved.
本发明涉及隔声设备领域，具体涉及一种层合结构隔声装置。包括依次层叠设置的复合阻尼隔声材料层、热熔胶层、橡胶阻尼层以及金属隔声层，所述热熔胶层上开设有空腔。通过设置依次层叠的复合阻尼隔声材料层、热熔胶层、橡胶阻尼层以及金属隔声层，其中，复合阻尼隔声材料层具有一定的阻尼性，可通过剪切、拉伸等形式来消耗声能，热熔胶层主要起到连接复合阻尼隔声材料层以及橡胶阻尼层的作用，但热熔胶层上开设的空腔可以使声能衰减并减弱共振吻合效应，橡胶阻尼层和金属隔声层组成约束阻尼隔声结构，以上各层相互配合，可以错开共振与临界吻合频率，从而达到轻质、高效隔声的效果。
