Could a vehicle levitate through use of ultrasonic sound waves?

In that question, I referenced how some scientists use acoustic levitation to suspend substances in the air, and wondered if that method could act as artificial gravity by pushing down on people. However, the answer I got was that the ultrasonic pressure would simply push down on exposed areas, not effect the person's entire mass like gravity does.

But that got me thinking: since they confirmed that ultrasonic frequencies push down on objects, would it be possible for the speakers producing the sound to push off the ground using ultrasonic waves, propelling the speaker (and the object it's connected to) into the air?

To specify, could this method be used to create a vehicle that levitates off of the ground?
