Abstract: An acoustic levitation apparatus and method for adaptively adjusting a resonance distance. The apparatus includes an acoustic receiver, an acoustic transmitter, a motor, a slide, and a signal feedback control module. The acoustic receiver and the acoustic transmitter are installed on the slide of which movement is controlled by the motor. The acoustic receiver is connected to the signal feedback control module. The signal feedback control module performs determination by detecting the magnitude of a signal outputted by the acoustic receiver and automatically controls the motor to adjust a spacing between the acoustic transmitter and the acoustic receiver to satisfy a resonance condition to form stable standing wave levitation. The acoustic transmitter is connected to an ultrasonic generator.
