    Abstract: An unmanned aerial vehicle (UAV) includes an audio source collecting microphone detecting a target audio signal, background noise-producing components producing background noise different from the target audio signal, background microphones collecting the background noise, and noise emitters each configured to reduce the background noise by emitting an audio signal having a reverse phase of the collected background noise collected by the corresponding background microphone. The background microphones further collect reduced background noise. The UAV further includes a processor receiving signals which comprise the target audio signal and the reduced background noise, and generating a processed signal based on the collected reduced background noise to reduce interference by the background noise to the target audio signal.

    Abstract: A camera includes a housing, a lens assembly accommodated in the housing, a plurality of circuit boards accommodated in the housing and including a first circuit board and at least one second circuit board, and a connection rod including at least one step member at a peripheral of the connection rod. One end of the connection rod is configured to fix the lens assembly in the housing. Another end of the connection rod is configured to connect with the first circuit board. One of the at least one second circuit board abuts against a corresponding one of the at least one step member and is fixed to the connection rod. The plurality of circuit boards are spaced apart from the lens assembly and from each other.
