Abstract

"ALTO-FALANTE". Um alto-falante (104) compreendendo uma estrutura em forma de caixa feita a partir de um material rígido em folha de peso leve, para a definição de uma pluralidade de faces (34), pelo menos uma face (34) da estrutura formando um irradiador acústico de onda direcionável em forma de painel e tendo um transdutor de vibração eletroacústico (106) acoplado a ele, para a aplicação de energia de onda direcionável ao irradiador, para se fazer com que ele irradie uma saída acústica, quando um sinal de entrada for aplicado ao transdutor, a estrutura em forma de caixa sendo colapsante, de modo que a estrutura em forma de caixa possa ser armazenada e transportada em uma forma plana e erguida como uma caixa, quando requerido, como um alto-falante.
