Digital Loudspeaker Arrays Driven by 1-bit Signals

Loudspeaker Arrays driven by digital bitstreams are direct digital-signal to acoustic transducers, usually comprising of a digital signal processing module driving actuators. Current research efforts are focusing on topologies directly driven by multi-bit digital bitstreams. In this work, the above investigations are extended to the case of using 1-bit signals such as Sigma-Delta for driving such topologies, using time and frequency domain analysis. Simulation results will be presented for idealized actuators. Finally, an optimized architecture for such a loudspeaker will be proposed, based on this analysis.
