    摘要： The invention relates to an electrodynamic transducer (1) having a dome membrane (2) comprising an electrodynamic motor with a coil (6) which is supported by a mandrel (3) that is solidly connected to the membrane which is suspended from a frame (7). The aforementioned coil is disposed in a gap in which it can move and which is defined at the centre by an inner magnetic structure (4) and at the periphery by an outer magnetic structure (5). According to the invention, the suspension does not contain a peripheral suspension nor an inner suspension. The inventive transducer comprises at least two means (11) for confining the magnetic field in the gap in order to form at least two tiered ferrofluidic seals (12, 13, 14) in the gap using a ferromagnetic liquid, such as at least to guide the coil and to form a pneumatic seal between the front and rear faces of the membrane, at least one of said ferrofluidic seals being continuous. The invention is suitable for loudspeakers.
