Abstract:
1. An electrocoustical transducer comprising: a first rigid sheet having a shape and a boundary and further having a width and a depth; a second rigid sheet; a spacing structure for spacing said first rigid sheet from said second rigid sheet to define an acoustic enclosure, said acoustic enclosure having a top, a bottom and a side edge, wherein said top includes said first rigid sheet and said bottom includes said second rigid sheet, said acoustic enclosure having a thickness between said top and said bottom, wherein said thickness is substantially less than said width and said depth; and a first acoustic transducer having a vibratable diaphragm constructed and arranged for exchanging first sound waves with said acoustic enclosure with only one side of said diaphragm; said enclosure having a first plurality of outlet points, whereby said first sound waves pass through said first plurality of outlet points, wherein said second rigid sheet is constructed and arranged to conform to a planar surface.
