More Information
Summary:Various mechanisms and methods for altering sound output from an unmanned aerial vehicle (UAV) are disclosed. The UAV can have a drive system comprising a motor or a plurality of motors, and a processor operatively coupled to the drive system to control operation of the drive system. The UAV can further have a plurality of propellers that are rotatably drivable by the drive system, the plurality of propellers having physical characteristics such that, when drivingly rotated to maintain the UAV in stable flight, a first of the plurality of propellers emits a first note, and a second of the plurality of propellers emits a second, different note, a combination of the first and second notes producing a consonant sound.
