SOUND ABSORBER AND SOUND ABSORPTION STRUCTURE
To provide a sound absorber or a sound absorption structure which is not affected by a dimension of a finishing material even if it is stored in the finishing material of a ceiling face and the like and can adjust a resonance frequency even if it is installed outside the ceiling face and the like.SOLUTION: A sound absorber body 20 includes an inner slit 23 and a cavity 3 connected to the inner slit, connects the inner slit with a space and absorbs sound in the space. A neck member 30 in which a neck is formed outside and/or inside the inner slit by attaching it near the inner slit is provided. Thus, a neck height L and/or a neck slit width b can be changed by attaching/detaching the neck member.SELECTED DRAWING: Figure 1
【課題】 天井面等の仕上げ材の中に収納する場合でも、仕上げ材の寸法の影響を受けず、また、天井面等の外に設置する場合でも共振周波数の調整が可能な吸音器及び吸音構造体を提供すること。【解決手段】 吸音器本体２０は内スリット２３とこの内スリットに連通する空洞３を有し、空間にこの内スリットを連通させて空間内の音を吸音する。内スリット近傍に取り付けることにより内スリットの外及び／または内にネックを形成するネック部材３０をさらに設け、このネック部材の着脱によりネック高さｌ及び／又はネックスリット幅ｂを変更可能である。【選択図】 図１
