Abstract: A portable public address (PA) speaker comprises an enclosure constructed and arranged for positioning at a first position having a vertical orientation to output audio shaped for a first acoustic coverage area, a second position having an angular orientation to output audio shaped for a second acoustic coverage area, and a third position having a horizontal orientation to output audio shaped for a third acoustic coverage area. The weight of the speaker rests on a bottom surface of a base when in the first position having the vertical orientation or the second position having the angular orientation. The weight of the speaker rests on a side surface when in the third position having the horizontal orientation.

Abstract: An array is provided that includes a plurality of drivers, each of the same size and type, to transduce processed audio signals into acoustic waves, an input to receive an audio signal and a control signal, and at least one signal processor to provide the processed audio signals in accord with the received audio signal and the control signal. The signal processor receives the audio signal and the control signal, and provides a first processed signal to a first driver based in part upon the audio signal and a first parameter received from the control signal, and provides a second processed signal to a second driver based in part upon the audio signal and a second parameter received from the control signal.

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.

Abstract: A loudspeaker includes a horn including a first end panel, a second end panel, a first side panel, and a second side panel. Edges of at least the first and second side panels define a diffraction slot opening. The first and second side panels are each fabricated from a sheet of flexible material held in a stressed, curved shape by at least a rigid support member. The panels are designed by an automated process based on a number of electro-acoustic transducers to be used in a loudspeaker, horizontal and vertical coverage angles for the loudspeaker, and a wall length for a horn of the loudspeaker.

Abstract: In general, in some aspects, a loudspeaker includes a horn including a first end panel, a second end panel, a first side panel, and a second side panel. Edges of at least the first and second side panels define a diffraction slot opening. A plurality of manifold components each has an output opening coupled to the diffraction slot opening. The output openings of the plurality of manifold components together constitute a diffraction slot source at the diffraction slot opening. A plurality of electro-acoustic transducers are each coupled to an input opening of one of the manifold components.
