Title (EN) EARPHONE WITH MOVABLE PUSHING BAR STRUCTURE
(FR) ÉCOUTEUR À STRUCTURE DE BARRE DE POUSSÉE MOBILE
(ZH) 活动式推杆结构的耳机
Abstract:
(EN) An earphone with a movable pushing bar (2) structure includes an outer shell (3), a speaker unit (4) assembled in the outer shell (3), a voice pipe (5) for voice transmission connected with the speaker unit (4), and an earplug (6) connected with the voice pipe (5). A gas pipe (31) for ventilating the gas both inside the earphone and outside the earphone is provided on the outer shell (3). The movable pushing bar (2) connected with the outer shell (3) for adjusting the ventilation condition of the gas pipe (31) is provided inside the outer shell (3). The gas pipe (31) can be airproofed by pushing the movable pushing bar (2) in order to realize a fully sealed type earphone, or the movable pushing bar (2) leaves the gas pipe (31) in order to realize an open type earphone.
(FR) La présente invention concerne un écouteur pourvu d'une structure de barre de poussée mobile (2) comprenant une coque extérieure (3), une unité haut-parleur (4) assemblée dans la coque extérieure (3), un conduit acoustique (5) de transmission des sons, relié à l'unité haut-parleur (4), et un bouchon d'oreille (6) relié au conduit acoustique (5). La coque extérieure (3) est pourvue d'un conduit à gaz (31) servant à la ventilation du gaz aussi bien à l'intérieur de l'écouteur qu'à l'extérieur de l'écouteur. La barre de poussée mobile (2) équipe l'intérieur de la coque extérieure (3) à laquelle elle est reliée de façon à régler l'état de ventilation du conduit à gaz (31). Le conduit à gaz (31) peut être rendu étanche à l'air en poussant la barre poussée mobile (2) de façon à réaliser un écouteur de type complètement étanche, la barre de poussée mobile (2) pouvant aussi sortir du conduit à gaz (31) de façon à réaliser un écouteur de type ouvert.
