Abstract

A mobile telephone (10) comprising a body (12) and a bending wave loudspeaker which comprises a panel-form member (14) capable of supporting bending waves and a transducer (24) mounted to the panel-form member to excite bending wave vibration in the panel-form member to produce an acoustic output, characterised in that the body (12) defines an open top cavity (16) and in that the panel-form member is movable between a first and a second position with the panel-form member covering the open top of the cavity (16) when in the first position and spaced away from the cavity when in the second position.
