Abstract

The visual display apparatus comprises a notice board or the like which incorporates the loudspeaker (81). The loudspeaker has a distributed acoustic mode radiator having a transducer (9) mounted wholly and exclusively on it to vibrate the radiator and cause it to resonate. The transducer may be a piezoelectric bender. Graphic information in the form of text or pictures may be printed on the panel which may be supported on a stand (23) or suspended from wires.
