Abstract
A decorative speaker cover and a method for fabricating a speaker cover for use in a ceiling or wall comprising panels, the speaker cover having an appearance which blends with other panels so that it conceals the presence of a speaker system while providing satisfactory transmission of sound from the speaker system. The decorative speaker cover is fabricated by first forming a mold liner suitable for generating a facsimile of a ceiling or wall panel. Next, the mold liner is placed in a molding container and a closed cell expandable foam system is uniformly spread over the mold liner so that the foam rises vertically. The thickness of the resulting cast is reduced to a dimension below which acoustic transmission loss is not discernable by human ears.
Claims8
A speaker cover for a loudspeaker system for installation in a ceiling or wall composed of panels having a predetermined visible, external appearance, said speaker cover comprising a thin sheet of closed cell foam having a concealed rear surface facing the loudspeaker system and a front visible surface which has the same visible appearance as the panels so that when the speaker cover is installed, said cover appears to be one of the panels of the ceiling or wall.
A speaker cover to be placed in front of a loudspeaker, which, when installed in a ceiling or wall having an ornamental relief pattern, comprises a thin sheet of closed cell foam having a concealed rear surface facing the loudspeaker and a visible front surface which forms part of the ornamental ceiling pattern so that the speaker cover does not appear distinct from the rest of the ceiling or wall.
