Abstract

An exciter capsule comprises an electromagnetic transducer (8) housed in a housing (12) and has means for electrically connecting to the audio output of an audio device, such as a mobile telephone. The capsule is mountable on a variety of resonant surfaces to provide a portable speaker system which may be used with portable audio devices, for example as part of a hands-free mobile telephone kit.
