L'élément décoratif comprend une partie de support et une partie de connexion reliée à la partie de support, la partie de support étant disposée sur la première surface, la partie de connexion étant insérée dans le trou de montage de la coque, la paroi latérale circonférentielle de la partie de connexion étant reliée de manière fixe à la paroi latérale intérieure du trou de montage au moyen d'une couche adhésive, une première rainure adhésive pénétrant la première surface et la seconde surface étant formée entre la paroi latérale circonférentielle de la partie de connexion et la paroi latérale interne du trou de montage, et la couche adhésive s'étendant de la première rainure adhésive vers la seconde surface et étant collée à la seconde surface pour former une structure inversée. La solution de la présente invention utilise l'agencement de la structure inversée de sorte que la couche adhésive ne tombe pas facilement de la seconde surface, augmentant efficacement la fiabilité d'assemblage de l'élément décoratif et de la coque. En outre, la présente invention concerne également un dispositif électronique fourni avec l'ensemble de coque et un procédé de préparation de l'ensemble de coque.
