Title
(EN) ACOUSTIC BOX
(FR) ENCEINTE ACOUSTIQUE
Abstract
(EN)
The present invention refers to an acoustic box equipped with at least one acoustic trasnducer in which said transducer (21) is assembled on one of the walls (11) of said acoustic box at a median position in relation to said wall (11) on which it is assembled, being that the diaphragm (22) of said transducer (21) faces the inner part of said acoustic box (10), facing a wall opposite (16) the wall on which it is assembled, thus enabling a substantial reduction in the size of the acoustic box, particularly its width (L).
(FR)
La présente invention concerne une enceinte acoustique équipée d’au moins un transducteur acoustique dans laquelle ledit transducteur (21) est assemblé sur l’une des parois (11) de ladite enceinte acoustique à une position médiane par rapport à ladite paroi (11) sur laquelle il est assemblé, le diaphragme (22) dudit transducteur (21) faisant face à la partie interne de ladite enceinte acoustique (10), face à une paroi opposée (16) à la paroi où il est assemblé, ce qui permet une réduction sensible de la taille de l’enceinte acoustique, en particulier quant à sa largeur (L).
