Abstract
Altavoz de teléfono móvil que comprende un imán permanente (1), una membrana (3), una primera bobina eléctrica (2) de excitación mecánica, móvil con respecto al imán y fijada a la membrana, y una segunda bobina eléctrica (6; 9), caracterizado porque la segunda bobina (6; 9)está bobinada en serie con la primera bobina (2)de manera que se produce una fuerza contraelectromotriz inversa de la producida por la primera bobina cuando éstas están sometidas ambas a un mismo campo electromagnético o magnético temporalmente variable, y porque la segunda bobina (6; 9) está mantenida fija con respecto al imán.
