Estimating the term…
A ribbon loudspeaker, according to the invention, comprises permanent magnets spaced from each other along an axis and making up a magnetic system, and sound-reproducing ribbons freely vibrating, independent of each other placed in a working gap between the poles of permanent magnets. The side surfaces of the permanent magnets are made convex and spaced from the axis, whereas their pole surfaces are made concave and spaced along the axis. The permanent magnets are magnetized by way of separate magnetization of their central parts in the plane of a sound-reproducing ribbon and portions adjoining their side surfaces. The proposed ribbon loudspeaker ensures higher fidelity of sound.
A ribbon loudspeaker comprising at least two permanent magnets together making up a magnetic system, said magnets being spaced from each other generally along an axis, each permanent magnet having a pair of generally convex opposing side surfaces spaced from said axis, and having a pair of generally concave opposing pole surfaces spaced from each other along said axis, the facing concave pole surfaces of two adjacent permanent magnets together defining a working gap;
