An acoustic transducer provided with at least one sound source for
generating an acoustic centre and a predetermined construction for
guiding sound generated by the acoustic centre, which acoustic transducer
can be fixed to a fixing wall, wherein the predetermined construction is
so designed that, during operation, the generated sound is displaced by
the predetermined construction to a displaced acoustic centre at a
location that is on the fixing wall (5), when the acoustic transducer
(10) is fixed to the fixing wall (5).
