Abstract

A portable device is provided for coupling acoustic energy into a surface whereby the surface radiates audible sound. The device comprises a body (1) containing an acoustic actuator (6) and means (3) for energising the actuator with an audiofrequency signal, the actuator having a foot (7) for coupling the acoustic energy into the surface, and a suction device (9) for temporarily attaching the device to a surface, the suction device comprising a flexible membrane (11) surrounding the foot, and lifting means (12, 13, 15) to exert a lifting force away from the surface on said membrane, thereby reducing the air pressure beneath said membrane to hold the portable device on the surface.
