Abstract
An unmanned aerial vehicle capable of employing active noise cancelling without being influenced by wind from a rotor is provided. The unmanned aerial vehicle includes a processor and at least one speaker. The processor acquires operational information regarding each of at least one generator and generates an opposite phase signal having an opposite phase relative to a signal corresponding to the operational information. The at least one generator generates a force to fly the unmanned aerial vehicle. The operational information correlates with noise generated by each of the at least one generator. The at least one speaker outputs sound based on the opposite phase signal.
