Abstract
Disposición de imanes, en particular para altoparlantes, micrófonos y similares, que comprende un núcleo con una placa de fondo de un material magnético blanco, un imán permanente anular preferentemente de material oxídico, axialmente magnetizado y provisto alrededor del núcleo, y una placa superior de material magnético blando, en que un entrehierro anular activo está formado entre la placa superior y el núcleo, caracterizada por el hecho de que el lado libre de la placa de fondo está provisto con un segundo imán permanente, preferentemente también de material oxídico, que está axialmente magnetizado en dirección opuesta con respecto al primer imán y que también tiene una altura menor, estando dimensionado el primer imán anular de modo de producir flujo substancialmente sólo en el entrehierro activo, mientras que entre la placa de fondo y el segundo imán está disponible un entrehierro de una altura tal y el segundo imán está dimensionado de modo, que éste último elimina el flujode dispersión desventajoso por lo menos en una parte considerable.
