  • Publication number: 20140020974
    Abstract: A ceiling speaker assembly is disclosed. In one or more embodiments, the ceiling speaker assembly includes a three-dimensional support frame attached to a perforated grille. The support frame is configured with a speaker aperture adjacent to which a speaker is mounted and a port aperture. The speaker aperture and port aperture are configured such that the speaker aperture is in communication with the front of the speaker and the port aperture is in communication with the rear of the speaker. In one or more embodiments, the support frame includes a horn cavity that functions as an acoustical cross-over such that higher frequencies generated by the speaker are emitted primarily through the speaker aperture and the lower frequencies generated by the speaker are emitted primarily through the port aperture.

  • Publication number: 20120080260
    Abstract: A method and apparatus for providing a loudspeaker assembly is provided. In accordance with at least one embodiment, a method is provided which comprises forming a loudspeaker frame so as to define a driver housing portion, a horn portion, and a conformal portion. A driver aperture is defined for the driver housing portion, and a port aperture is defined for the horn portion. A driver is attached to the loudspeaker frame proximate to the driver aperture. A rear baffle is applied to a first conformal portion surface of the conformal portion of the loudspeaker frame. The rear baffle defines a horn cavity wall of a horn cavity of the horn portion. The horn cavity has an increasing cross sectional area as the distance from the driver housing portion increases. A grille is applied to a second conformal portion surface of the conformal portion of the loudspeaker frame.
