Abstract:
1. A loudspeaker comprising: a bearing structure; a magnetic arrangement fixed to the bearing structure, the magnetic arrangement defining air-gaps, and a diaphragm connected to the bearing structure, made of a sheet material, characterized by: the diaphragm has a cylindrical jacket-like shape consisting of segments; the segments are connected to each other along delimiting lines running in the direction of the generating lines, and they have a surface curvature of which is larger than a curvature that belongs to an overall radius of the cylindrical jacket-like shape; there are flaps at least along two delimiting lines, which the flaps extend into the air-gaps each radially; and the diaphragm is connected to the bearing structure with flexible supporting units joining the flaps and allowing radial movement of the flaps in the air-gaps.
