Abstract

"CAIXA ACúSTICA". A presente invenção refere-se a uma caixa acústica dotada de pelo menos um transdutor acústico em que dito transdutor (21) é montado em uma das paredes (11) da dita caixa acústica em uma posição mediana em relação à dita parede (11) na qual está montado, sendo que o diafragma (22) do dito transdutor (21) fica voltado para o lado interno da dita caixa acústica (10), de frente para uma parede oposta (16) à parede na qual está montado, desse modo permitindo uma redução substancial do tamanho da caixa acústica, particularmente de sua largura (L).
