Abrégé

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.

Abrégé

The invention relates to an electrodynamic transducer (1) including: a magnetic circuit (2) that defines an air gap (15); a movable part (16) that includes a dome-shaped diaphragm (17) rigidly connected to a movable spool (18) that is placed down into the air gap (15); a holder (20) on which the movable part (16) is hung; and a hanging part (26) that ensures the connection between the movable part (16) and the holder (20). Within said transducer, the holder (20) extends at least partially into an inner space to the movable part (16), the hanging part (26) is attached, by an outer periphery, to an inner surface of the movable part (16), and the hanging part (26) is made of an acoustically non-emissive material.
