An air moving device includes a film structure, a first actuator and a second actuator. The film structure includes a flap pair, wherein the flap pair includes a first flap and a second flap opposite to each other. The first actuator is disposed on the first flap, and the second actuator is disposed on the second flap. The first actuator includes a first electrode and a second electrode, and the second actuator includes a third electrode and a fourth electrode. The first electrode receives a first demodulation signal and the third electrode receives a second demodulation signal, such that the flap pair performs a differential-mode movement. The second electrode and the fourth electrode receive a modulation signal, such that the flap pair performs a common-mode movement.
