Title (EN) INVERTED BUTTON CAP IN ACOUSTIC TRANSDUCER
(FR) CAPUCHON DE BOUTON INVERSÉ DANS UN TRANSDUCTEUR ACOUSTIQUE
Abstract:
(EN) An inverted button cap of an electroacoustic transducer has a diaphragm, a bobbin coupled to the diaphragm, and a dust cap supported by the bobbin and coupled to the diaphragm via the bobbin. The dust cap includes a concave surface that faces outwardly away from the bobbin. According to an example, an adhesive joint couples the diaphragm, dust cap, and the bobbin to provide a seal at the junction of the diaphragm and the bobbin. A convex surface of the dust cap, opposite the concave surface, extends into a cavity formed by the bobbin.
(FR) Un capuchon de bouton inversé d'un transducteur électroacoustique a un diaphragme, une bobine couplée au diaphragme et un capuchon antipoussière supporté par la bobine et couplé au diaphragme par l'intermédiaire de la bobine. Le capuchon antipoussière comprend une surface concave qui est tournée vers l'extérieur à l'opposé de la bobine. Selon un exemple, un joint adhésif couple le diaphragme, le capuchon antipoussière et la bobine pour fournir une étanchéité à la jonction du diaphragme et de la bobine. Une surface convexe du capuchon antipoussière, opposée à la surface concave, s'étend dans une cavité formée par la bobine.
