Abstract

"ALTO-FALANTE". A presente invenção refere-se a um alto-falante compreendendo um alojamento fornecido com uma unidade de ímã que gera um campo magnético, e uma membrana que é montada em uma armação e que é fornecida com um condutor elétrico disposto em um padrão na membrana, cuja membrana é posicionada no campo magnético de tal maneira que uma força é exercida quando a corrente é alimentada através do padrão condutor na membrana, cuja força é capaz de colocar a membrana em movimento de modo a produzir som, em que o padrão condutor é fornecido na membrana em pelo menos duas regiões de vibração espaçadas, em que o alto-falante é fornecido com pelo menos dois canais de som se estendendo entre as duas regiões de vibração e o lado externo do alojamento e em que os eixos centrais dos dois canais de som, que são localizados entre a parede externa e a parede interna de cada canal, se inclinam na direção uma da outra sobre uma distância particular da membrana.
