Acoustic radiation suppression device and acoustic radiation suppression structure
The invention provides sound radiation suppression equipment and a sound radiation suppression structure. The sound radiation suppression equipment comprises a frame, a mass area and a bottom plate, the mass area is located in the frame, and a hollow area is further arranged in the frame; one side of the frame is connected with the bottom plate, and the other side of the frame is directly or indirectly connected with the surface of an external structure to be subjected to sound insulation; the mass area is attached to one side of the bottom plate; and the surface of an external structure to be subjected to sound insulation, the frame and the bottom plate are encircled to form a sealed area. The frame comprises an elastic sealing frame and a middle frame; the mass area comprises a central mass area, an external mass area, a first connecting structure and a second connecting structure; through the design of the central mass area, the external mass area, the first connecting structure, the second connecting structure, the bottom plate and the middle frame, vibration of an external structure to be subjected to sound insulation is subjected to positive and negative offset in different areas in the sound radiation suppression equipment, so that the purpose of weakening sound radiation caused by resonance is achieved.
本发明提供了一种声辐射抑制设备及声辐射抑制结构。所述声辐射抑制设备，包括框架、质量区以及底板；所述质量区位于在所述框架内，框架内还设置有镂空区域；框架的一侧与底板相连，另一侧直接或间接的与外界待隔声结构表面连接；所述质量区附着在底板的一侧；外界待隔声结构的表面、框架、底板三者合围，形成密封区域。所述框架包括弹性密封框与中框；所述质量区包括中心质量区、外部质量区、第一连结结构以及第二连结结构；本发明通过中心质量区、外部质量区、第一连结结构、第二连结结构底板以及中框的设计，使外界待隔声结构的振动在声辐射抑制设备内部的不同区域发生正负抵消，以达到削弱谐振引起的声辐射目的。
