Abstract
An acoustic array system includes a sound field controller and an acoustic transducer array. The sound field controller provides first and second processed signals. The first processed signal is associated with a first acoustic radiation pattern and the second processed signal is associated with a second acoustic radiation pattern. The transducer array receives the first and second processed signals from the sound field controller and produces first and second driver signals for each of the transducers. The first driver signals are based upon the first processed signal and the second driver signals are based upon the second processed signal. The transducer array combines the first and second driver signals for each of the transducers to produce a plurality of combined driver signals, one for each of the transducers, and provides the combined driver signals to the transducers.
