Abstract

Dans la présente invention, une paire d'éléments de maintien (3a, 3b) sont positionnés l'un en face de l'autre avec un espace prescrit entre eux et sont reliés par une partie de liaison (5). La partie de liaison (5) est une substance élastique et permet de maintenir un dispositif d'écoute (1), avec des oreillettes maintenues entre les éléments de maintien (3a, 3b) et de fixer le dispositif d'écoute (1) aux oreilles. La partie de liaison (5) est configurée principalement à partir d'un matériau central et d'un élément de protection, etc. le matériau central est tubulaire et est constitué, par exemple, d'un alliage à mémoire de forme à base de NiTi. Un fil électrique (13) est inséré à l'intérieur du matériau central. La forme en coupe transversale du matériau central est une forme plate repliée dans la direction d'une courbe. Du fait qu'il est configuré de cette manière, le matériau central peut être facilement déformé dans la direction de la courbe.
