Abstract:
A horn loudspeaker comprising:an electroacoustic transducer for converting an electrical signal adapted to be applied to an input terminal thereof into sound; a sound conduit having first and second ends with said first end coupled to said transducer, for transmitting sound emitted by said transducer to said second end thereof, wherein a cross-section of said sound conduit in a plane perpendicular to the direction of propagation of the sound in said sound conduit has a straight, elongated shape, and a horn coupled to said second end of said sound conduit for propagating the sound supplied through said sound conduit in a desired direction in at least one propagation plane; wherein said sound conduit is coupled to that position of a wall of said horn which lies in a plane paralleling said propagation plane; and said horn is arranged in such a manner that the sound is propagated from said portion of said horn where said second end of said sound conduit is coupled over a sectoral range in said propagation plane, and the direction of elongation of the cross-section of said sound conduit at said second end is along the bisector of the sectoral range.
