Title (EN) EAR UNIT AND PORTABLE SOUND DEVICE
(FR) UNITÉ D'OREILLE ET DISPOSITIF SONORE PORTABLE
Abstract:
(EN) An ear unit and a portable sound device having the same are provided. The ear unit includes a driver unit, an ear housing configured to form an electric part in which the driver unit is mounted and including a bass hole and a flat hole formed in a first surface of the electric part, a rotator including a second surface opposite the first surface and rotatably coupled to the ear housing, and an opening/closing hole provided in the second surface of the rotator to open or close the bass hole or the flat hole according to rotation of the rotator. The flat hole is connected to an inner hole formed in one position inside the first surface so as to form a duct.
(FR) L'invention concerne également une unité d'oreille et un dispositif sonore portable comprenant celle-ci. L'unité d'oreille comprend une unité de commande, un logement d'oreille configuré pour former une partie électrique dans laquelle l'unité de commande est montée et comprenant un trou de basse et un trou plat formé dans une première surface de la partie électrique, un rotateur comprenant une seconde surface opposée à la première surface et couplée de manière rotative au logement d'oreille, et un trou d'ouverture/fermeture disposé dans la seconde surface du rotateur pour ouvrir ou fermer le trou de basse ou le trou plat en fonction de la rotation du rotateur. Le trou plat est relié à un trou interne formé dans une position à l'intérieur de la première surface de façon à former un conduit.
