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.

La présente invention concerne un appareil acoustique comprenant un réseau de haut-parleurs caractérisés en ce qu'ils comprennent des éléments résonnants en forme de panneaux auxquels sont associés des excitateurs de vibrations permettant d'appliquer une énergie d'ondes de flexion sur lesdits éléments, de manière à ce qu'ils résonnent et produisent un signal de sortie acoustique, et qu'ils sont disposés à proximité les uns des autres afin de produire des signaux de sortie acoustiques sensiblement non corrélés et un signal de sortie acoustique global fonctionnant sensiblement comme une source acoustique unique.
