Abstract: The invention concerns a pneumatic loudspeaker, fed by a gas stream under pressure flowing through a sonic throat (62) and modulated by axial displacement of a mobile element in the annular air gap of a magnetic circuit formed by axially stacked discs of permanent magnets (24) and of soft iron (26) inside a soft iron yoke (16). The invention enables the miniaturisation of high acoustic power pneumatic loudspeakers.
