Description
上述した課題を解決するために本発明は、中空であって、外面から内面に貫通した貫通孔と、外面から内面に貫通した少なくとも2つの通気孔を有する筐体と、音響透過性を備え、前記筐体外から前記通気孔を通って前記筐体内に送られた空気が前記筐体外から空気が送られた通気孔とは異なる通気孔を通って前記筐体外へ抜けるように前記筐体の中空部分を仕切る通路形成部材とを有する吸音構造体を提供する。 In order to solve the above-described problem, the present invention is hollow and includes a through-hole penetrating from the outer surface to the inner surface, and a housing having at least two vent holes penetrating from the outer surface to the inner surface, and has sound permeability. The casing is hollow so that air sent from the outside of the casing through the ventilation hole into the casing passes out of the casing through a different ventilation hole from the outside of the casing. providing the sound absorbing structure having a passage forming member for partitioning portion.
また、本発明においては、弾性を有する板状または膜状の振動体で前記貫通孔が塞がれている構成であってもよい。
また、本発明においては、前記貫通孔と前記筐体内の空気によりヘルムホルツの共鳴が生じる構成であってもよい。
また、本発明においては、前記貫通孔に管状部材が挿入されている構成であってもよい。
Moreover, in this invention , the structure by which the said through-hole is block | closed with the plate-shaped or film-shaped vibrating body which has elasticity may be sufficient.
In the present invention, Helmholtz resonance may be generated by the air in the through hole and the housing.
Moreover, in this invention, the structure by which the tubular member is inserted in the said through-hole may be sufficient.
本発明においては、前記通路形成部材は筒状の構成であってもよい。
また、本発明においては、前記通路形成部材は、板状または膜状である構成であってもよい。
In the present invention, the passage forming member may have a cylindrical configuration.
In the present invention, the passage forming member may have a plate shape or a film shape .
