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 ).
