Abstract:
The invention relates a horn-based multi-driver wide-bandwidth loudspeaker with a flat-frequency response having the property of controlled acoustic directivity at wavelengths larger than the nominal wavelength supported by the horns' mouth circumference which is provided by means of a centerbody fitted with acoustic drivers that are acoustically coupled to the walls of the horn enclosure.

Claim (Index 1):
An acoustic horn comprising an acoustic enclosure extending along a longitudinal axis, the acoustic enclosure having an acoustically open end, an acoustically closed end, and acoustically closed narrowing sides having interior walls and;\n an elongated centrally-located having an exterior wall, and a distal vertex and a proximal vertex, the centerbody containing one or more acoustic transducers and one or more acoustic ports, the centerbody extending along the longitudinal axis and the narrowing sides of the enclosure to form an annular acoustic channel defined by the interior walls of the acoustic enclosure and by the exterior walls of the centerbody, at least one high frequency range driver being acoustically coupled to the proximal vertex of the centerbody; and the centerbody having a rear surface, the rear surface coupled to the narrowing sides, and the centerbody further having a frontal surface, wherein the centerbody extends along the longitudinal axis in a first plane and in a second plane, and the second plane is inclined relative to the first plane, and in the first plane and in the second plane, the rear surface tapers outward along the longitudinal axis following a surface of the enclosure to a transition, and the first front surface tapers inward along the longitudinal axis from the transition toward the open end, so as to form an expanding annular passage defined by the acoustic enclosure and the centerbody exterior wall.
