Abstract
【解決手段】アクチュエータ103の駆動ロッド103aはパイプ102の下端部側の端面に当接している。アクチュエータ103は、パイプ102の下端部側の端面から、この端面に直交した方向(面方向)の振動成分をもって、パイプ102を加振する。パイプ102の下端部側の端面は縦波で励振され、このパイプ102を、弾性波(振動)が面方向に伝播していく。そして、この弾性波がパイプ102を伝播する際に縦波、横波、縦波・・・のモード変換を繰り返し、縦波と横波との混在波となり、横波によってパイプ102の面内方向(面に垂直な方向)の振動が励振され、音波が放射される。パイプ102の加振点に大きな横波は発生せず、この加振点からの音波が他の位置からの音波に比べて非常に大きな音として聴取されるということがなく、広がり感のある音像を得ることが可能となる。
