The present invention relates to a vibro-acoustic insulating module device (100; 200; 300; 400), comprising: six mass elements (101; 201; 301; 401) respectively adjacent and not joined; at least twelve stiffness elements (102; 202; 302; 402) configured for mechanically interconnecting the six mass elements (101; 201; 301; 401) in the module device (100; 200; 300; 400). Each mass element (101; 201; 301; 401) comprises at least four anchor elements (103; 203; 303; 403) for respect at least four stiffness elements (102; 202; 302; 402) of the at least twelve stiffness elements (102; 202; 302; 402). Each of these at least four stiffness elements (102; 202; 302; 402) connects respectively each mass element (101; 201; 301; 401) to four mass elements (101; 201; 301; 401) of said six mass elements (101; 201; 301; 401), the four mass elements (101; 201; 301; 401) being adjacent to said each mass element (101; 201; 301; 401). The present invention also relates to a vibro-acoustic insulating periodic structure (600).

Abstract
The present invention relates to a vibro-acoustic insulating module device (100; 200; 300; 400), comprising: six mass elements (101; 201; 301; 401) respectively adjacent and not joined; at least twelve stiffness elements (102; 202; 302; 402) configured for mechanically interconnecting the six mass elements (101; 201; 301; 401) in the module device (100; 200; 300; 400). Each mass element (101; 201; 301; 401) comprises at least four anchor elements (103; 203; 303; 403) for respect at least four stiffness elements (102; 202; 302; 402) of the at least twelve stiffness elements (102; 202; 302; 402). Each of these at least four stiffness elements (102; 202; 302; 402) connects respectively each mass element (101; 201; 301; 401) to four mass elements (101; 201; 301; 401) of said six mass elements (101; 201; 301; 401), the four mass elements (101; 201; 301; 401) being adjacent to said each mass element (101; 201; 301; 401). The present invention also relates to a vibro-acoustic insulating periodic structure (600).| File | Dimensione | Formato | |
