Abstract

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.

IPC Classes  ?

• H04R 9/04 - Construction, mounting, or centering of coil
• H04R 7/16 - Mounting or tensioning of diaphragms or cones
• H04R 7/12 - Non-planar diaphragms or cones

Abstract

The invention relates to a coaxial speaker system (1) having at least two channels and including an electrodynamic woofer transducer (2) and a tweeter transducer (3) that has a compression chamber coaxially and frontally mounted relative to the woofer transducer (2).

IPC Classes  ?

• H04R 1/24 - Structural combinations of separate transducers or of parts of the same transducer and responsive respectively to two or more frequency ranges
• H04R 1/30 - Combinations of transducers with horns, e.g. with mechanical matching means
• H04R 9/06 - Loudspeakers
• H04R 9/02 - Transducers of moving-coil, moving-strip, or moving-wire type Details

Abstract

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.

Abstract

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 diaphragm (17) and a movable spool (18) that is rigidly connected to the diaphragm (17) and is placed down into the air gap (15) of the magnetic circuit (2); and an acoustic waveguide (44) that is rigidly connected to the magnetic circuit (2) and defines at least one horn cap (54). Said electrodynamic transducer is characterized in that the waveguide (44) is made of a highly heat-conductive material and has, on the periphery thereof, raised areas for promoting the dissipation of heat produced in the magnetic circuit (2).
