Abstract

La présente invention porte sur un écouteur gonflable (4) qui est façonné pour une insertion et un placement dans un canal auditif externe (2). L'écouteur comporte un ballonnet gonflable (7) qui peut être sélectivement gonflé et dégonflé. Lorsque le ballonnet est gonflé, il se dilate et vient s'appuyer contre les parois du canal auditif (2). L'écouteur est muni d'un module de réception (5) avec un générateur de sons (12) et une connexion vers un dispositif extérieur (par exemple une prothèse auditive, un lecteur MP3, un téléphone cellulaire). Les ondes sonores générées dans le module de réception sont guidées vers le tympan (3) par l'intermédiaire d'un support (6) qui maintient également le ballonnet (7). Un ensemble pompe et soupape est intégré dans le module de réception de façon à sélectivement gonfler ou dégonfler le ballonnet (7). La pompe est reliée par l'intermédiaire d'une coupelle de collecte (12) qui entoure l'extrémité avant du récepteur (5), au travers des petits espaces formés par un raccordement par encliquetage entre le récepteur (5) et le support (6), et au travers d'une ou plusieurs ouvertures de gonflage (9) débouchant dans le ballonnet (7). Cette connexion fluidique est scellée de manière étanche par rapport à l'intérieur du canal auditif (2) et par rapport à l'extérieur par l'intermédiaire d'un ensemble d'étanchéité (16, 17, 20). Le module de réception (5) et le module de ballonnet (6, 7) sont symétriques en rotation l'un par rapport à l'autre, c'est-à-dire qu'ils peuvent être raccordés dans toute orientation de rotation et aucun alignement rotatif des parties n'est nécessaire pour raccorder le module à ballonnet (6, 7) au module de réception (5, 12).
