Abstract

Un mode de réalisation de la présente invention concerne un écouteur. Selon des modes de réalisation de la présente invention, un écouteur porté sur une oreille d'un utilisateur comprend : un corps principal comprenant une partie de couplage à laquelle est couplé un élément en silicone qui peut être fixé/détaché; une partie de support ayant une forme incurvée et comportant une extrémité couplée au corps principal et l'autre extrémité faisant face au corps principal; et une partie de sortie sonore qui est couplée au corps principal, est disposé face à une surface arrière de l'oreillette lorsque l'écouteur est porté sur l'oreille de l'utilisateur, et est en contact étroit avec une première région sur la surface arrière de l'oreillette, la partie de support pouvant avoir une élasticité telle que le corps principal, auquel l'élément en silicone est couplé, peut être en contact étroit avec la surface arrière de l'oreillette.
