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.

摘要： The invention is intended to enhance the driving efficiency in a speaker being less in distortion. In order to achieve the purpose, there is provided a damper disposed rather closer to a magnetic circuit than the diaphragm, of which the inner rim is connected to a voice coil body, and the outer rim of the damper is connected to the frame via the second edge. The second edge is protruded toward the diaphragm or the opposite side thereof. The damper has such a structure that the first protrusion protruding toward the diaphragm and the second protrusion protruding in a direction opposite to the first protrusion are alternately repeated in a plurality of times, and the first protrusion and the second protrusion are different in size from each other. The smaller protrusion out of the first and second protrusions is same in protruding direction as the second edge.

摘要： A vibration actuator includes an electro-mechanical transducer having a magnetic circuit (1-4) and a driving coil (5), a support frame (9), and a damper (270) elastically supporting the magnetic circuit onto the support frame to flexibly damp the vibration of the magnetic circuit when a driving AC current is supplied to the coil (5). The damper (270) comprises an inner and an outer ring portions (271, 272) and a plurality of spiral spring portions (273) determined by a plurality of spiral slits (274, 275) formed in the damper. In order to reduce the spiral spring portion determined by the adjacent two spiral slits in its compliance, each of the spiral spring portions has an effective spring length determined by an effective angle (υ) which is determined as an angle (by angular degree) from an inner end of the inner spiral slit to an outer end of the outer spiral slit of thereof around a center of the damper. The effective angle is 55 angular degree or more. In a preferable example, the effective spring length is determined by a product (r.υ) of an average radius (r) value by the unit of 'mm' and the effective angle (υ) value by unit of the angular degree. The effective spring length is selected of 320 or more, preferably, 400 or more.
