Claims (1)
象を利用して共振周波数付近の音波を吸収する吸
音装置において、前記振動板が吸音しない周波数
の音波を乱反射するように少なくとも一部が音波
の入射方向に対して傾斜した形状を有することを
特徴とする吸音装置。 (2) 前記振動板が波形形状である実用新案登録
請求の範囲第(1)項記載の吸音装置。 (3) 前記振動板の全体が一方向に傾斜し、かつ
複数の振動板を並設して表面を凹凸状にした実用
新案登録請求の範囲第(1)項記載の吸音装置。[Claims for Utility Model Registration] (1) In a sound absorption device in which a diaphragm is placed in an opening in the front of a box body and uses a resonance phenomenon to absorb sound waves near the resonant frequency, the diaphragm absorbs sound waves at frequencies that are not absorbed by the diaphragm. A sound absorbing device characterized in that at least a portion thereof has a shape inclined with respect to the incident direction of a sound wave so as to diffusely reflect the sound wave. (2) The sound absorbing device according to claim (1), wherein the diaphragm has a waveform shape. (3) The sound absorbing device according to claim 1, wherein the entire diaphragm is inclined in one direction, and a plurality of diaphragms are arranged in parallel to form an uneven surface.
