Abstract
【解決手段】吸音シート16がスピーカーグリル14の立下り部14bと内装トリム12とで挟持されているので、スピーカー18から流れる音によってスピーカーグリル14が振動しても、吸音シート16の挟持部分では吸音シート16による吸音効果により、立下り部14bと内装トリム12との間で異音の原因となる擦れ音が生じることはない。また、スピーカーグリル14の立下り部14bと導音筒32とで形成された空間Xの開口が吸音シート16で覆われているので、スピーカーグリル14の振動によって生じ、空間X内に伝達された振動音が効率よく吸収される。したがって、異音の他の原因となる反響音が空間X内において生じることもない。
