Abstract

Apparatus (1) comprising a bending wave panel loudspeaker having a bending wave panel (5) defining a surface and an electro-acoustic transducer (15) attached to the bending wave panel to excite bending waves in the panel to produce an acoustic output, an input device (11) forming part of the surface and means (13) for providing force-feedback to the input device. The panel provides several functions and may be considered to be a hyper-functional surface (HFS).
