Abstract

Acoustic apparatus comprising an array of loudspeakers characterised in that the loudspeakers comprise resonant panel-form members having vibration exciters associated therewith to apply bending wave energy to the panel-form members to cause them to resonate to produce an acoustic output and in that the panel-form loudspeakers are proximately arranged to produce substantially uncorrelated acoustic outputs and overall acoustic output substantially as though a single acoustic source.
