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."SPEAKER". A speaker (104) comprising a box-like structure made from a light weight rigid sheet material, for defining a plurality of faces (34), at least one face (34) of the structure forming a panel-shaped steerable acoustic radiator and having an electro-acoustic vibration transducer (106) coupled thereto for the application of steerable wave energy to the radiator to cause it to radiate an acoustic output when an input signal is applied to the transducer, the box-like structure is collapsing so that the box-like structure can be stored and transported in a flat shape and lifted as a box, when required, as a speaker.
