Abstract

A loudspeaker (104) comprising a box-form structure made from stiff lightweight sheet material to define a plurality of faces (34), at least one face (34) of the structure forming a panel-form bending wave acoustic radiator and having an electro-acoustic vibration transducer (106) coupled thereto to apply bending wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the traducer, the box-form structure being collapsible, so that the box-form structure can be stored and transported in a flat form and erected as a box when required as a loudspeaker.
