Loudspeaker arrangement

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 defines 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 waveguide defines a central axis as a line that is perpendicular to a plane defined by the entrance of the waveguide and intersects the entrance plane at its center.
