Abstract The present invention provides a box-shaped soundproof structure that is compact, lightweight, and capable of sufficiently reducing noise having a frequency specific to a sound source. The box-shaped soundproof structure includes a box body that is open at least in part thereof and a muffler structure including a resonator disposed inside the box body. The muffler structure reduces sound generated by a sound source disposed in contact with the outer wall of the box body or inside the box body and released to the outside via the open face of the box body. L'invention concerne une structure d'insonorisation en forme de boîtier qui est compacte, légère et capable de réduire suffisamment le bruit ayant une fréquence spécifique à une source sonore. La structure d'insonorisation en forme de boîtier comprend un corps de boîtier qui est ouvert au moins en partie, ainsi qu'une structure de silencieux comprenant un résonateur disposé à l'intérieur du corps de boîtier. La structure de silencieux réduit le son généré par une source sonore disposée en contact avec la paroi extérieure du corps de boîtier ou à l'intérieur du corps de boîtier et diffusée à l'extérieur par la face ouverte du corps de boîtier. 小型軽量で、音源に固有の周波数の騒音を十分に消音できる箱型防音構造体を提供する。少なくとも一部が開放された箱体と、箱体の内部に配置される共鳴体を含む消音構造と、を有し、箱体の壁の外側面に接して、または、箱体の内部に、配置される音源から発生して箱体の開放面から外部に放射される音を消音構造によって低減する。
