Abstract
A loudspeaker assembly includes an enclosure having an open front side and a wall having an interior surface and an exterior surface with a wall thickness defined therebetween. The wall is integrally molded with a screw boss supported by a plurality of molded ribs that extend inwardly from the interior surface. The loudspeaker assembly also includes an audio transducer positioned within the enclosure and having an output side facing the open front side of the enclosure to emit sound therefrom; and a mount for securing the transducer to the enclosure via a screw threaded into the screw boss. At a meeting point with the interior surface, each of the plurality of molded ribs has a rib thickness measured perpendicular to the wall thickness, the rib thickness being less than 50 percent of the wall thickness to avoid sink marks in the injection molded part.
