Un zumbador perfeccionado, caracterizado esencialmente por que sobre un soporte en U se fija a su fondo una bobina, cuyo núcleo sobresale ligeramente, y a una de las ramas del soporte se fija un fleje en L, con su zona de vértice de menor anchura y sinuoso, para dar mayor flexibilidad a la rama suelta de la L, que enfrentada al núcleo del electroimán, es atraída por este en los pasos de corriente, efectuando percusión en el extremo del soporte que queda ligeramente más adelantado que el núcleo.
