Abstract

La présente invention a trait à un visiocasque qui comprend : un corps d'afficheur ; un serre-tête (12) relié au corps d'afficheur et destiné à être porté par un utilisateur ; un casque d'écoute (10) comportant un corps de casque d'écoute (100) et un bras de liaison (101) qui sont fixés l'un à l'autre ; un élément de positionnement (11) relié au serre-tête (12), l'élément de positionnement (11) ayant au moins deux surfaces de positionnement (110), et le bras de liaison (101) étant relié rotatif à l'élément de positionnement (11) de telle sorte que ce bras de liaison (101) soit solidarisé séparément auxdites surfaces de positionnement (110) ; et un mécanisme de verrouillage élastique pouvant fournir, lorsque le bras de liaison (101) tourne pour se solidariser à n'importe laquelle des surfaces de positionnement (110), une force élastique permettant de fixer ledit bras de liaison (101). Ce visiocasque résout un problème technique, à savoir la mauvaise expérience utilisateur due au fait que l'angle entre le casque d'écoute (10) et la tête de l'utilisateur soit fixe lorsque ledit casque d'écoute (10) est combiné et coordonné avec le visiocasque d'un seul bloc.
