Abstract

A wide-band loudspeaker comprising strip diaphragm to which electrically conductive wires (2) are connected, and magnets (3) having air-gaps. The diaphragm (1) consists of one or more, preferably two strips (4) having a quadrilateral shaped surface, the strips (4) are arcuated along their longitudinal axis, and along their adjacent edges they form parallel double edges (5). In case of separate strips (4) the adjacent edges are fixed to each other. The outer edge (7) of the outside strips (4) and the positioning of the magnet (3) are fixed relative to each other, and the double edges (5) are positioned in the air-gaps preferably along their entire length, and in one or more windings the electrically conductive wire (2) is fixed to the double edges (5).
