Digital loudspeaker

A loudspeaker comprising a plurality of transducers configured to emit acoustic signals at a predetermined frequency which is equal or greater than any frequency of sampling of an audible acoustic signal, and arranged so that the acoustic signals converge at a same focus in phase,

• wherein the loudspeaker has a configuration in which a digital signal, being formed of successive bit sequences each comprising bits representative of the amplitude of the audible acoustic signal at a time sample, the bits of each bit sequence including at least one quantification bit, is used in a manner so that successively, for each bit sequence, the or each quantification bit is associated to at least one of the transducers and independently governs, depending on a value and a rank of the quantification bit, at least two different amplitudes of the acoustic signals emitted by the transducer or each of the transducers associated to the quantification bit, in a manner so as to obtain a carrier wave of the audible acoustic signal that is modulated in at least two different amplitudes according to the digital signal.
