VIBRATION ATTENUATION PANEL WITH LOUDSPEAKER

摘要

A vibration attenuation panel (1Oa-IOd), comprising an inboard layer (16) defined by a first thickness (Ti); and an outboard layer (18) defined by a second thickness (To), wherein the outboard layer (18) includes a reduction in the second thickness (To) to define a gap (32) to define a substrate attenuation portion (28) and a substrate body portion (30), wherein the substrate attenuation portion (28) is substantially vibrationally-isolated from the substrate body portion (30).
