Abstract
A loudspeaker includes a box-form structure made from stiff lightweight sheet material to define a plurality of faces, at least one face of the structure forming a panel-form bending wave acoustic radiator, and an electro-acoustic vibration transducer 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 transducer. The box-form structure is 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.

A loudspeaker, comprising:
- a box-form structure made from stiff lightweight sheet material to define a plurality of faces, at least one face of the structure forming a panel-form bending wave acoustic radiator;
- and
- an electro-acoustic vibration transducer coupled to the at least one face to apply bending wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the transducer,
- wherein the box-form structure is collapsible to a flat form for at least one of storage and transportation and re-erectable as a box form for use as a loudspeaker.
