Abstract

Altavoz en forma de conjunto alargado, llamado altavoz lineal, constituido por un cuerpo en forma de paralelepípedo alargado hueco (1), una cara longitudinal del cual está constituida por lo menos en parte por una membrana plana (7) de forma rectangular alargada, suspendida por sus bordes (10) en las caras laterales adyacentes (2) de dicho cuerpo (1) o debajo del fondo (3) de dicho cuerpo (1), y solidaria de un ala rígida interna alargada (11) que se extiende en la dirección longitudinal de dicho cuerpo (1), sensiblemente en el plano medio longitudinal (P) del mismo, y que lleva una bobina electromagnética móvil (13) de perfil alargado, dispuesta entre dos imanes alargados fijos (5), asociados a partes polares fijas, caracterizado por el hecho de que la bobina electromagnética móvil (13) queda paralela a la membrana (7), y en que los dos imanes alargados fijos (5) entre los cuales va dispuesto están colocados respectivamente a lo largo de dos caras laterales longitudinales (2) de dicho cuerpo (1), de manera que tales caras laterales (2) y el fondo (3) del cuerpo (1) forman dichas partes polares fijas, comprendiendo también una parte polar central fija (4), situada en el plano longitudinal medio (P) del cuerpo (1) y alojada en un hueco longitudinal (12) del ala rígida interna (11) de la membrana (7), estando dicha membrana (7) tensa a fin de permitir su deformación simétrica a uno y otro lado de su posición de reposo, durante el movimiento vibratorio de dicha membrana (7) al excitar el altavoz.
