Abstract
A line source loudspeaker device positionable in a mutually orthogonal first and a second position includes a housing with a first loudspeaker for emitting high frequencies and one or more second loudspeakers for emitting low frequencies. The loudspeakers each include a driver and loudspeaker output. Each driver emits a spherical sound wave. The loudspeaker outputs form a combined loudspeaker output. An acoustic waveguide is provided between the combined loudspeaker output and the first loudspeaker to guide the spherical sound waves emitted by the first loudspeaker over a constant wave path and convert them into a rectangular isophase sound wave which interferes constructively with the sound waves of the second loudspeakers to form a cylindrical sound wave. The acoustic waveguide is rotatable about an axis such that, in the first and second position of the line source loudspeaker device, the cylindrical sound wave propagates only in a horizontal direction.
