An enclosure (1) for an acoustic transducer (2) comprises a first chamber (11) for accommodating the acoustic transducer (2) and a spaced apart second chamber (12), which first and second chambers are acoustically coupled by a coupling section (15). The coupling section may have a smaller diameter than the first and the second chamber. An optional further coupling section (16) may acoustically couple the first chamber (11) to an optional third chamber (13). The volume of the enclosure is distributed over the various chambers, thus providing a relatively large enclosure, even when the first chamber (11) is small. Any non-fundamental resonances induced by the coupling sections (15, 16) lie outside the active region of the transducer (2). ® KIPO & WIPO 2007
