Abstract

A loudspeaker arrangement comprises a loudspeaker including a diaphragm to transmit an audio output, a light source, and a waveguide surrounding the diaphragm, and configured to control directivity of the audio output, wherein the waveguide comprises an entrance at a first axial end, a mouth at a second axial end of the waveguide opposite the entrance, and a throat extending between the entrance and the mouth, the loudspeaker is positioned at the entrance of the waveguide, and the throat of the waveguide includes at least one surface area of a first kind and at least one surface area of a second kind, wherein each surface area of the at least one surface area of the first kind extends between the entrance and the mouth of the waveguide at a first angle with respect to a central axis, and wherein each surface area of the at least one surface area of the second kind extends between the entrance and the mouth of the waveguide at a second angle with respect to a central axis of the waveguide, wherein the second angle is greater than the first angle, and wherein the central axis of the waveguide is a line that is perpendicular to plane defined by the entrance of the waveguide and intersects the entrance plane at its center.
