description Disclosed is a loudspeaker enclosure including: -at least two sources suitable for producing ultrasound signals, and-a supply designed to process and amplify at least one input signal so as to produce, for the sources, supply signals of the same frequency and of different phases, wherein the supply are configured to apply different gains and/or phase shifts to at least two different frequency components of at least one of the supply signals. Also disclosed is a method for signal modulation for such an ultrasonic loudspeaker enclosure.
