Abstract
【解決手段】 管110−1は、管の長手方向に沿った4個の空洞120−m(m=1〜4)を内包しており、それぞれの空洞120−m(m=1〜4)は、管110−1の幅方向に並んでおり、仕切り130−i(i=1〜3)によって分割されている。また、管110−1の正面側には、管110−1が有している空洞120−m(m=1〜4)を、管110−1の外側の空間(音響空間)に各々連通させるための開口部140−j(j=1〜4)がそれぞれ設けられている。この開口部140−j(j=1〜4)は、管110−1の長手方向の同じ位置に設けられている。

Description
<実施形態>
図1(a)は、この発明の一実施形態による音響構造体を示す正面図であり、図1(b)は、同音響構造体のX−X´線断面図であり、図1(c)は、同音響構造体のY−Y´線断面図である。この音響構造体は、n本(nは複数)の管110−n(n=1〜6)が並列に並べられてパネル状に結合されている。本実施形態による音響構造体は、管110−n(n=1〜6)の厚みを小さくするとともに、幅を大きくすることにより、十分な散乱効果および吸音効果の得られる管の断面積を確保する一方、幅の広い管の中に管を幅方向に分割する仕切りを設けて、音響構造体の強度を補ったものである。
以上が本実施形態による音響構造体の構成である。
以上、この発明の一実施形態について説明したが、この発明には他にも実施形態が考えられる。例えば次の通りである。
