Description
筒状部材と、
上記筒状部材と同軸的に配置され、音声信号に基づいて駆動される発音体とを備え、
上記発音体から得られる音波を、上記筒状部材の一端側および他端側から放射する
ことを特徴とするスピーカ装置にある。
このスピーカ装置100Gによれば、パイプ102Gの下端部側および上端部側の双方から音波が放射されるものであり、パイプ102Gの長手方向の各位置で均一な音圧を感じることができ、パイプ102Gの長手方向の全体に渡って音像を定位させることができ、従って広がり感のある音像を得ることができる。この場合、スピーカユニット104はパイプ102Gの長手方向の中心部に配設されているため、このパイプ102Gの下端部側および上端部側から放射される音波のレベルをほぼ等しくでき、パイプ102Gの長手方向の各位置でより均一な音圧が得られるようになる。
このスピーカ装置100Hによれば、パイプ102の下端部側および上端部側の双方から音波が放射されるものであり、パイプ102の長手方向の各位置で均一な音圧を感じることができ、パイプ102の長手方向の全体に渡って音像を定位させることができ、従って広がり感のある音像を得ることができる。
