Abstract

L'invention concerne une balle de golf (5) dont la surface extérieure comporte une pluralité d'alvéoles (200, 202, 204) sélectionnées en fonction de trois ensembles. Le rayon de chaque ensemble d'alvéoles possède une valeur différente. Ces alvéoles (200, 202, 204) sont disposées sur la surface de la balle selon une configuration polygonale du type dodécaèdre rhomboïdal.
