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)."Acoustic box". The present invention relates to a speaker having at least one sound transducer wherein said transducer (21) is mounted on one of the walls (11) of said speaker in a mid-position with respect to said wall (11) on the which diaphragm (22) of said transducer (21) faces the inner side of said speaker (10), facing a wall opposite (16) to the wall on which it is mounted, thereby allowing a substantial reduction in speaker size, particularly its width (L).
