Title (EN) DOUBLE ANNULAR RING SPEAKER GASKET
(FR) DOUBLE JOINT ANNULAIRE DE HAUT-PARLEUR
Abstract:
(EN) A double annular ring gasket (202) interfaces a speaker (201) to a housing (200) in a portable radiotelephone, providing a conformal and acoustic seal between the speaker (201) and the housing (200), and compensating for dimensional tolerances between the housing (200) and the circuit board subassembly (204) on which the speaker (201) is mounted. The gasket (201) includes outer ring (205), inner ring (206) and intermediate ring (207) therebetween. The gasket (202) is inserted into a cavity (203) in the housing (200). Then, the speaker (201), as part of a printed circuit board subassembly (204), is pressed into place against the outer ring (205) of gasket (202) to form an axial seal and the inner ring (206) is deformed radially by the speaker (201) to form a conformal seal.
(FR) Double joint annulaire (202) servant d'interface entre un haut-parleur (201) et un boîtier (200) d'un radiotéléphone portatif et formant un joint d'étanchéité acoustique et conformable entre le haut-parleur (201) et le boîtier (200) et compensant les tolérances dimensionnelles entre le boîtier (200) et le sous-ensemble de carte de circuits (204) sur lequel le haut-parleur (201) est monté. Le joint (201) comprend une bague extérieure (205), une bague intérieure (206) et, entre les deux, une bague intermédiaire. Le joint (202) est inséré dans une cavité (203) du boîtier (200). Ensuite, le haut-parleur (201), en tant que partie d'un sous-ensemble de carte de circuits imprimés (204), est mis en place par pression contre la bague extérieure (205) du joint (202) pour former un joint d'étanchéité axial et la bague intérieure (206) est déformée radialement par le haut-parleur (201) pour former un joint d'étanchéité conformable.
