Abstract

L'invention concerne un élément de fixation de module électroacoustique, un ensemble électroacoustique, un dispositif électronique et un dispositif à porter sur soi, qui appartiennent au domaine technique des dispositifs intelligents. Dans la présente invention, un premier support est relié à un second support par encliquetage dans une première direction en ayant recours à l'insertion d'une première structure à insertion et d'une seconde structure à insertion et au moyen de l'encliquetage d'une première structure à encliquetage et d'une seconde structure à encliquetage ; et une première plaque latérale de support et une seconde plaque latérale de support viennent respectivement en butée contre une plaque latérale de support dans une seconde direction, de sorte que la stabilité de la liaison entre le premier support et le second support peut être assurée, évitant ainsi le problème du jeu.
