Apparatus for levitating and transporting object

An apparatus for levitating and transporting an object, comprising:

• a pair of elongated vibrators;
• a pair of oscillators, each of which includes a horn and a transducer, wherein each oscillator corresponds to one of the vibrators, wherein the transducer of each oscillator vibrates the corresponding vibrator through the corresponding horn to generate sound waves from the vibrator, wherein the object is levitated by radiation pressure of the sound waves;
• and
• a pair of flection limiting rods, wherein each flection limiting rod corresponds to one of the vibrators, wherein each rod contacts the lower surface of the corresponding vibrator at a position where the displacement due to vibration is relatively small and reduces the flection of the vibrator due to the weight of the vibrator and the weight of the transported object.
