Abstract

Patente de Invenção:<B>"OBJETO ACúSTICO"<D>. Trata-se de um aparelho acústico que compreende um arranjo de alto-falantes, caracterizado pelo fato de os altos-falantes compreenderem membros em formas de painel ressonantes tendo excitadores de vibração associados com o mesmo de modo a aplicar uma energia de onda em curva aos membros em forma de painel a fim de fazê-los ressonar para produzir uma saída acústica e pelo fato de que os altos-falantes em forma de painel são arranjados em proximidade de modo a produzir uma saída acústica substancialmente não correlacionada e uma saída acústica geral substancialmente como uma fonte acústica única.
