Abstract
【解決手段】 木材の中間層に木材とは音響特性の異なる材料を挟みこんでなる積層合板によりスピーカ等の筐体を構成する。木材に挟む中間層は、例えば紙である。紙を挟むことにより積層合板の内部損失を高くし、音響特性を調整する。紙を積層合板の表面または裏面の一方に偏らせて配置することにより、積層合板の表面の音響特性と裏面の音響特性を異ならせることができる。
【選択図】図1
Description
図1(a)〜(d)は、本発明の一実施形態であるスピーカキャビネット用積層合板の構成例を示す断面図である。本実施形態による積層合板は、薄い木材の層を複数積層するとともに、それらの木材層のうちの隣接した一部の木材層間に紙などの異種材料からなる層を挟んでなるものである。
Claims (4)
- 木材の中間層に木材とは音響特性の異なる材料を挟みこんでなる積層合板により少なくとも一部が構成されていることを特徴とする音響装置の筐体。
- 前記木材の中間層に挟みこまれた材料が紙であることを特徴とする請求項1に記載の音響装置の筐体。
- 木材の中間層に木材とは音響特性の異なる材料を挟みこんでなる積層合板であり、中間層が当該積層合板の厚み方向において当該積層合板の一方の面側に偏って設けられていることを特徴とする積層合板。
- 前記中間層が木材層と区別することができるように着色されていることを特徴とする請求項3に記載の積層合板。
