Abstract

Baffle réflexe pour ondes sonores arrière d'un haut-parleur situé, avec un évent, sur la face antérieure d'une enceinte. Les faces intérieures de celle-ci, réfléchissantes aux ondes sonores, constituent partie de la surface d'un tore, tel qu'un ellipsoïde de révolution, dont l'un des foyers est situé au voisinage du centre d'émission du haut-parleur, tandis que l'autre foyer est de préférence situé sur l'évent, où il coïncide avec le foyer d'un paraboloïde de révolution, une surface plane réfléchissante, située en vis-à-vis, étant positionnée à quarante-cinq degrés par rapport aux axes focaux communs des deux corps de révolution. Industries électriques et électroniques surtout concernées.
