Abstract

A loudspeaker assembly for use in electronic devices especially hand held communication devices e.g. a cellular mobile telephone, comprising a loudspeaker (12) for emitting sound through a front cover (9), and a board (8) for mounting components, the board (8) having a first side (10) carrying user interface means (5) accessible through the front plate (9), and a second side (11), facing towards a back cover (7). The loudspeaker (12) is mounted between the board (8) and the back cover (7). Thereby the electronic devices can be made very compact.
