Claims (5)
- 車室内空間と車室外空間との間に配置され、前記車室内空間と車室外空間を連通する開口部が設けられた支持部材と、前記開口部と対向するように前記支持部材に支持されたスピーカと、前記開口部を塞いで前記スピーカとの間に閉鎖空間を画成するリアカバー体とを備え、
前記リアカバー体は、前記支持部材に支持された環状可撓性部材と、前記環状可撓性部材の内側に支持され該環状可撓性部材よりも受圧面積の大きい非可撓性振動板とからなり、
前記スピーカは、前記支持部材に取り付けられたフレームと、前記フレームに保持されて前記閉鎖空間を介して前記リアカバー体に対向する振動板と、前記振動板に取り付けられたボイスコイルと、前記フレームに支持されて前記車室内空間内に位置する磁気回路とを備え、前記振動板の振動によって発生する音が前記フレームに形成された切欠き孔を通って前記車室内空間に放射されるように構成されていることを特徴とする車載用スピーカシステム。 - 請求項1の記載において、前記環状可撓性部材は、前記支持部材に取り付けられた部分から前記非可撓性振動板に取り付けられた部分に至るまでの断面形状が非直線状であることを特徴とする車載用スピーカシステム。
- 請求項1の記載において、前記環状可撓性部材の外径が前記振動板の直径よりも小さいことを特徴とする車載用スピーカシステム。
- 請求項1の記載において、前記非可撓性振動板が前記車室外空間側に膨出する円椀状であることを特徴とする車載用スピーカシステム。
- 請求項1の記載において、前記スピーカを駆動する駆動手段の駆動周波数帯域が前記閉鎖空間の共鳴周波数よりも低いことを特徴とする車載用スピーカシステム。
