Abstract (en)
[origin: WO2011086302A1] The invention relates to an electrodynamic transducer (1) including: a magnetic circuit (2) that defines an air gap; a movable part (16) that includes a dome-shaped diaphragm (17) and a movable spool (18) rigidly connected to the diaphragm (17) and placed down into the air gap; a holder (20) on which the movable part is hung; and a hanging part (34) that ensures the connection between the movable part (16) and the holder (20), said hanging part (34) being buoyant relative to the holder (20), thus allowing a radial degree of freedom.
