Description
本発明は、音を吸収する吸音構造体に関する。 This invention relates to a sound absorbing structure for absorbing sound.
本発明は、板・膜振動型の吸音構造体において、当該吸音構造体における吸音効率を高めることのできる吸音構造体を提供することを目的とする。 It is an object of the present invention to provide a sound absorbing structure that can enhance sound absorbing efficiency in the sound absorbing structure of the plate / membrane vibration type.
上述した課題を解決するために、本発明が採用する吸音構造体の構造は、開口部を有する筐体と、前記開口部に設けられ、前記筐体内に密閉された空気層を画成する板状または膜状の振動体と、前記振動体の外側に離間して設けられ、前記振動体に入射する音に対して略垂直方向から入射する成分を持たせるための流路を複数形成する流路形成手段と、を具備することを特徴とする。 In order to solve the above-described problems, the structure of the sound absorbing structure adopted by the present invention includes a housing having an opening and a plate that is provided in the opening and defines an air layer sealed in the housing. Or a film-like vibrating body and a flow that is provided on the outside of the vibrating body so as to have a component that is incident on the vibrating body from a substantially vertical direction with respect to the sound incident on the vibrating body. And a path forming means.
