Abstract

Una bocina (1, 1') para altoparlantes (2,2') fabricada con neodimio, con posibles placas planas superior (6) que tienen una forma tal como para obtenerse mayores volumenes de aire para ventilacion (5, 5'), una mayor disipacion térmica y una mayor distancia (D, D') entre las superficies (3, 3') en sentido diametral de imanes (2, 2') y las superficies internas (4, 4') de las mencionadas bocinas. La bocina tiene forma convexa y la relacion entre el diámetro medio (A) respecto de la pared interna en el codo, y el diámetro externo (B) oscila entre 1,4 y 1,8.
