Claim Text:
1. An air purification method performed by a control circuit of an air purification system, the method comprising: providing a plurality of flexible wires in a chamber including at least one air inlet and at least one air outlet, the plurality of flexible wires hanging downward in the chamber; generating, under control of the control circuit, a standing sound wave in the chamber to deform the plurality of flexible wires by a force caused by the standing sound wave such that portions of the plurality of flexible wires converge to one or more nodes of the standing sound wave; spraying, under control of the control circuit, droplets in the chamber; and generating airflow from the air inlet to the air outlet, whereby the droplets move to the one or more nodes of the standing sound wave, while trapping particles in the air during the movement to the one or more nodes, and the droplets are adsorbed to the plurality of flexible wires at the one or more nodes.
