Ceiling or wall-mounted loudspeaker system with anti-diffraction wave launch device

Image Number 3 for United States Patent #8014545.

A loudspeaker system includes an enclosure having an open end defining a plane, a baffle, a loudspeaker operating in the 4 kHz to 10 kHz range, and a device, preferably a ribbed portion having a plurality of grooves, coupled to the baffle for modifying the spectral profile of the projected sound waves. The baffle includes first and second angled surfaces each oriented at an oblique angle with respect to the plane. The speaker is coupled to the first angled surface and the ribbed portion is coupled to the baffle along the intersection of the first angled surface and the second angled surface. When mounted in a wall or ceiling, the system projects a sound field substantially indistinguishable from that of a loudspeaker located within the listener's listening plane. The baffle can also have acoustic damping material attached thereto, with grooves formed therein, to prevent reflections of 4 kHz to 10 kHz sound.
