Abstract (en)
[origin: EP2696598A2] A magnetic assembly (100) for a loudspeaker comprising permanent magnets (3) arranged in a ring in central symmetry between two polar plates (1, 2) coupled so as to form a magnetic circuit air gap (4), which polar plates (1, 2) comprise external rings (10, 22) provided with petals (12, 21) in correspondence with the permanent magnets (3). Said magnetic assembly (100) provides ribs (26) on a basis (20) of a first polar plate (2), adapted to at least partially occupy a cavity of the air gap (4) in correspondence with interstices between the adjacent permanent magnets (3). (Figure 1)
