Abstract

"COPO DE ALTO-FALANTE COM IMãS DE NEODìMIO". Um copo (1, 1') para alto-falantes (2, 2') de neodímio, com discos planos superiores possíveis (6) tendo uma forma tal de modo a obter: maiores volumes de ar de ventilação (5, 5'), maior dissipação térmica e maior distância (D, D') entre as superfícies diametrais (3, 3') dos imãs (2, 2' ) e as superfícies internas (4, 4') dos citados copos. O copo tem uma forma convexa e a razão entre o diâmetro médio (A) em relação à parede interna no ponto de flexão e o diâmetro externo (B) variar entre 1,4 e 1,8."SPEAKER CUP WITH NEODYMIA MAGNETS". A glass (1, 1 ') for neodymium speakers (2, 2'), with possible upper flat discs (6) having such a shape in order to obtain: higher volumes of ventilation air (5, 5 ') , greater thermal dissipation and greater distance (D, D ') between the diametral surfaces (3, 3') of the magnets (2, 2 ') and the internal surfaces (4, 4') of the aforementioned cups. The cup has a convex shape and the ratio between the average diameter (A) in relation to the internal wall at the point of flexion and the external diameter (B) varies between 1.4 and 1.8.
