Abstract

Patente de Invenção:<B>"ALTO-FALANTES EM FORMA DE PAINEL"<D>. Um alto-falante na forma de painel compreende pelo menos dois painéis acústicos de modo distribuído ressonantes com um único impulsionador provido para excitar todos os painéis de tal maneira que a energia de curva de onda é eficientemente transferida para cada um deles de modo a excitar a ressonância de modo distribuído nos mesmos a fim de prover uma saída acústica. Devem existir dois painéis, um maior do que o outro - o maior tendo uma rigidez de curva de onda inferior do que o menor. O painel menor fica posicionado excentricamente com relação ao maior e o impulsionador excentricamente com relação ao painel menor. Uma pluralidade de painéis menores pode ser associado com um único painel maior. Uma modalidade provê um impulsionador montado ao ou em cada painel menor que fica adesivamente preso face à face no painel maior. Uma outra modalidade provê o ou cada painel menor formado dentro e preso no painel maior, um impulsionador sendo preso no ou cada painel menor. A fixação dos painéis utiliza um material que forma um acoplamento de controle correspondente. Uma terceira modalidade provê o ou cada painel menor montado em uma extremidade de um acoplador associado que atravessa e se prende no painel maior, um impulsionador sendo preso na outra extremidade do ou de cada acoplador. A fixação do ou de cada acoplador ao painel maior utiliza um material que forma um acoplamento de controle correspondente. O ou cada acoplador é tubular em seção.
