Abstract
Abstract A loudspeaker having a magnet housing and mounting flange is mounted within an enclosure including an inner member of corrugated fiberboard cut at angles to the corrugations thereof to define hingedly interconnected panels foldable to form a generally prismoidal housing with a speaker opening in one wall and with support panels extending from the bottom of the housing and recessed to receive the speaker magnet housing therein to support same. The walls of the corrugated housing are held in assembled configuration by interlocking tabs and slots and interlocking tongues and recesses, and the speaker mounting flange overlies the outer surface of the one wall and is trapped thereagainst by a face panel of corrugated fiberboard. An outer member of corrugated fiberboard with a decorative outer cover sheet thereon is folded around and adhesively secured to the corrugated housing, the inner and outer fiberboard members and the face panel cooperating to provide each wall of the enclosure with two layers of corrugated fiberboard having corrugations disposed at angles to each other. A perforated grille board is secured to the outer surface of the face panel. The margins of the outer corrugated member are pressed together with the cover sheet to form flattened edges to facilitate insertion of the bottom edges in a flanged baseplate and the top edges in a flanged trim frame encompassing the one wall, the trim frame having integral stakes extending through the grille board to facilitate attachment thereof.
