Abstract (en)
The present invention derives from the technical area of object levitation; it relates to an acoustic levitation system comprising an emitter (2) and a reflector (1) with in-between an object (19), respectively matter is levitated due to a standing acoustic pressure wave (15). According to the invention the standing acoustic pressure wave (15) provides a line-shaped pressure node (12) between the corresponding to that line-shaped pressure node (12) formed emitter (2) and reflector (1), so that the object, respectively matter (19) is able to move along the line-shaped pressure node (12).
