Zusammenfassung:Inertial electroacoustic transducer unit (300; 400) comprising a first exciter (100) and a second exciter (200), the second exciter (200) is disposed in overturned position on the first exciter (100), that is to say in a first configuration the bases (41) of the two cups (40) face each other, or in a second configuration the cavities of the two cups face each other; the two exciters (100, 200) are fixed together or to a plane intended to be put into vibration in such manner that the axes (A) of the cylindrical supports (10) of the coils coincide, the ends of the coils (1) of the two exciters being connected in counter-phase in such manner to obtain a consistent movement in the same direction as the magnetic units (4) of the two exciters.
