Directional Loudspeaker

A loudspeaker for use in the audio spectrum with directional effect along a main axis extending from a front side of the loudspeaker, comprising:

• a housing,
• at least one sound source arranged in the housing, which sound source is configured to produce sound waves substantially in a first frequency range lying between a lower frequency and an upper frequency, wherein the produced sound waves comprise front waves on the front side of the sound source and comprise rear waves on the rear side of the sound source, and
• an acoustic horn which extends between a neck and a mouth along a horn axis, which neck is acoustically coupled to the front waves and which horn has a directional effect along the main axis for front waves lying in a second frequency range and having a frequency higher than a midfrequency lying between the lower and upper frequency,
• wherein the loudspeaker comprises an attenuation axis lying at an angle relative to, preferably opposite the main axis, and is configured to obtain for front waves and rear waves lying in a third frequency range and having a frequency lower than the midfrequency, and by means of a phase shift between the respective rear waves and front waves obtained by means of a difference between a rear propagation time to the attenuation axis for rear waves and a front propagation time to the attenuation axis for front waves, a directional effect along the main axis for front waves with a frequency in the third frequency range by destructive interference between the respective rear waves and front waves around the attenuation axis.
