PROBLEM TO BE SOLVED: To provide a floating device for an object using little electric power, with a simple constitution and a large floating distance, to be operated by an acoustic wave generating little noise. SOLUTION: Acoustic energy from an acoustic energy generation means 2 easily obtainable by using acoustic resonance pipe 1 is amplified. A floating energy supply plate 4 is mounted in an upper part of the acoustic resonance pipe 1, a radiation pressure is generated by vibrating this plate 4 between itself and a floated object 6, floating force is obtained, by acoustic energy from the acoustic resonance pipe 1. Since the acoustic energy uses a low order resonance frequency of the resonance pipe 1, very large floating force can be obtained. |
