Abstract
An air-pulse generating device and an airflow generating method are disclosed. An air-pulse generating device includes a flap pair, including a first flap and a second flap opposite to each other. The first flap and the second flap oscillate at an oscillation frequency and oscillate in an out-of-phase fashion with each other; wherein during an oscillation of the flap pair, the flap pair forms a virtual valve or an opening at an opening rate corresponding to the oscillation frequency.
