By means of an elongated, electrically conductive diaphgram (1, 1A, 1B) in a strongly magnetic field, a linear and an elongated sound source giving a high sound energy is obtained. At least two elongated diaphragms (1, 1A, 1B) are in accordance with the invention positioned between intermediate and enclosing protracting magnet elements (2, 2A, 2B, 4), whereby the transverse length (A) of the diaphragms (1, 1A, 1B) are at least of the same size as that (B) of the intermediate protracting magnet elements (2, 2A, 2B, 4). In this way, a sound without considerable interference merges at a short distance from the sources of the sound. By placing additional such sources of sound alongside each other, a broad sound source with a surface producing an essentially homogeneous sound field is achieved.
La présente invention concerne une source sonore linéaire et oblongue produisant un son puissant produite au moyen d'une membrane électro-conductrice oblongue (1, 1A, 1B) disposée dans un champ magnétique puissant. Selon la présente invention, au moins deux membranes oblongues (1, 1A, 1B) sont disposées entre des éléments magnétiques intermédiaires (2, 2A, 2B, 4) d'encadrement allongés, la longueur transversale (A) des membranes (1, 1A, 1B) étant au moins égale à la longueur transversale (B) des éléments magnétiques intermédiaires (2, 2A, 2B, 4). Ce dispositif permet la fusion d'un son sans interférences considérables à faible distance des sources sonores. La disposition côte à côte des sources sonores additionnelles permet de réaliser une source sonore large dont la surface produit un champ sonore sensiblement homogène.
