PROBLEM TO BE SOLVED: To improve sound absorption performance with a simple structure and to make acoustic change without lowering designability.SOLUTION: A sound absorption structure (1) comprises: a rear face part (21) which has a length in a predetermined direction; a front face part (22) which is arranged apart in parallel with the rear face part (21) and in front of the rear face part (21); a sound taking-in port (23) which is located in the front face part (22) and has an opening width in the predetermined direction; and a sound absorbing material (3) which absorbs a sound entering through the sound taking-in port (23). The sound absorbing material (3) is arranged from one end of the front face part (22) in the predetermined direction to the other end part in a region (24) between the rear face part (21) and front face part (22). The sound absorption structure (1) further comprises an opening width adjustment member (5), which can adjust an opening width (Dx) of the sound taking-in port (23).SELECTED DRAWING: Figure 1
【課題】簡易な構造で吸音性能を向上可能であり、かつ、意匠性を低下させることなく音響を可変とすること。【解決手段】吸音構造(1)は、所定方向に長さを有する後方面部(21)と、後方面部(21)と平行かつ後方面部(21)から前方に離れて配置された前方面部(22)と、前方面部(22)内に位置し、所定方向に開口幅を有する音取入れ口(23)と、音取入れ口(23)を介して入射する音を吸収する吸音材(3)とを備える。吸音材(3)は、後方面部材(21)と前方面部材(22)との間の領域(24)内において前方面部(22)の所定方向一方端部から他方端部に沿って配置されている。吸音構造(1)は、開口幅調整部材(5)をさらに備えており、開口幅調整部材(5)によって音取入れ口(23)の開口幅(Dx)が調整可能である。【選択図】図1
