Loudspeaker

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.

A loudspeaker assembly includes an enclosure defining a direction for projecting sound, a first transducer and a second transducer positioned within the enclosure, an acoustic horn coupled with the first transducer, a mounting baffle secured to the enclosure for supporting the second transducer, and a port establishing fluid communication along a port length between the interior of the enclosure and an outside environment in front of the open front side of the enclosure. The acoustic horn has a surface facing an interior of the enclosure. A forward portion of the port is formed by a forward face of the mounting baffle and an extension wall depending from the acoustic horn in a direction transverse to the direction. The port length is extended by a rearward port portion formed by a rearward extending flange of the mounting baffle and a rearward projection extending from the surface of the acoustic horn.
