Abstract

La présente invention concerne le domaine technique de la lévitation d'objets; elle concerne un système de lévitation acoustique comprenant un émetteur (2) et un réflecteur (1) entre lesquels est inséré un objet (19); une matière est lévitée du fait de l'onde de pression acoustique constante (15). Selon l'invention, l'onde de pression acoustique constante (15) fournit un nœud de pression en forme de ligne (12) entre l'émetteur formé en fonction de ce nœud de pression en forme de ligne (12) et le réflecteur (1), de sorte que la matière respective de l'objet (19) peut se déplacer le long du nœud de pression en forme de ligne (12).
