Abstract
The invention provides an enclosure arrangement for a loudspeaker (10) adapted to be mounted in a voice communication terminal. The invention provides primary and secondary enclosures for the loudspeaker. The primary enclosure comprises a piece of resilient open cell foam material (15) having one face provided with a concavity suitable for receiving the spider (12) and the voice coil structure (11) of the loudspeaker (10). The peripheral edge of the one face of the foam material (15) is secured to the peripheral edge (14) of the spider (12) and the outer surface of the foam material has a flexible layer (16) of substantially air-impermeable material, whereby the loudspeaker is provided with an attached flexible enclosure (33). The secondary enclosure comprises the housing (30) in which the loudspeaker is mounted. The flexibility of the primary enclosure allows energy to be coupled between itself and the secondary enclosure.
