Abstract
La présente invention est un procédé qui permet d'éliminer les vibrations mécaniques, produites par la mise en mouvement des membranes des haut-parleurs, entre les différents éléments constituant une enceinte acoustique. L'élimination de ces vibrations est assurée par un joint de composition souple servant de liaison entre les différentes parties de l'enceinte et permettant par sa consistance d'absorber toutes les vibrations qui lui sont appliquées.
