Title (EN) SOUND REDUCTION OR VIBRATION DAMPING DEVICE AND STRUCTURAL MEMBER
(FR) DISPOSITIF D'INSONORISATION OU D'AMORTISSEMENT DES VIBRATIONS, ET ÉLÉMENT STRUCTURAL
(JA) 音低減又は振動減衰装置及び構造部材
Abstract:
(EN) Provided is a sound reduction or vibration damping device having a new sound control principle totally different from the sound control principles of conventional passive or active sound control devices. This sound reduction or vibration damping device (1) is provided with a mass part (11), a spring part (12a, 12b) interposed between the mass part (11) and a structural member (13), and a control unit (4) which continues to change the spring constant of the spring part (12a, 12b). This sound reduction or vibration damping device (1) is mounted to the structural member (13), and reduces sound transmitted through the structural member (13) or sound generated from the structural member, or damps the vibration of the structural member (13).
(FR) La présente invention concerne un dispositif d'insonorisation ou d'amortissement des vibrations, reposant sur un nouveau principe de contrôle des sons totalement différent des principes de contrôle des sons des dispositifs de contrôle des sons actifs ou passifs classiques. Ce dispositif d'insonorisation ou d'amortissement des vibrations (1) comprend une partie masse (11), une partie ressort (12a, 12b) interposée entre la partie masse (11) et un élément structural (13), et une unité de contrôle (4) qui continue à changer la constante de rappel de la partie ressort (12a, 12b). Ce dispositif d'insonorisation ou d'amortissement des vibrations (1) est monté sur l'élément structural (13), et réduit les sons transmis à travers l'élément structural (13) ou les sons générés à partir de l'élément structural, ou amortit les vibrations de l'élément structural (13).
(JA)  従来のパッシブ又はアクティブの制音装置とは制音原理が全く異なる新たな制音原理を持つ音低減又は振動減衰装置を提供する。 本発明の音低減又は振動減衰装置1は、質量部11と、質量部11と構造部材13との間に介在するばね部12a,12bと、ばね部12a,12bのばね定数を変化させ続ける制御部4と、を備える。本発明の音低減又は振動減衰装置1は、構造部材13に装着され、構造部材13を透過する音若しくは構造部材から発生する音を低減し、又は構造部材13の振動を減衰する。
