Abstract

Un transductor telefónico mejorado compuesto de un subconjunto magnético motriz acoplado a un subconjunto de armadura conducido, en el que dicho subconjunto magnético tiene un alojamiento en forma de cazoleta no magnética con una cavidad central definida por una pared lateral cilíndrica una base y una cubierta, alojándose en dicha cavidad los componentes magnéticos motrices entre los que se encuentra un número de piezas polares cuyas caras polares quedan en una posición fija frente a una armadura de dicho subconjunto conducido, extendiéndose dichas piezas polares por una ranura al menos de dicha base y estando llena la cavidad de dicha cazoleta con un compuesto de relleno que mantiene a dichas caras polares en dicha posición fija en un plano paralelo a un plano determinado por la superficie del borde inferior de dicha pared lateral de la cazoleta.
