The invention relates to the technical field of unmanned aerial vehicle sound amplification equipment, and provides an unmanned aerial vehicle sound amplification device which comprises an unmanned aerial vehicle body and a storage box arranged below the unmanned aerial vehicle body, the storage box is internally provided with sound amplification equipment used for sound amplification of a loudspeaker on the unmanned aerial vehicle body, and the storage box is provided with a storage mechanism used for storing the sound amplification equipment. The effect of enlarging the volume of an auxiliary loudspeaker on the unmanned aerial vehicle is achieved through the sound amplifying device arranged in the storage box, the effect of rotating and closing the baffle to isolate the storage box is achieved through mutual cooperation of an annular rack and a shielding gear, the air pressure in the storage box is larger than the air pressure around the storage box under the action of the Bernoulli principle, and the storage box is more stable. The phenomenon that dust suspended in the air enters the storage box and the inside of the sound amplification equipment under the action of pressure difference is avoided, the damage to the sound amplification equipment due to moisture absorption of the dust is avoided, and therefore protection of the sound amplification equipment is improved.

    本发明涉及无人机扩音设备技术领域,提出了一种无人机扩音装置,包括无人机本体,以及无人机本体下方设置的收纳箱,所述收纳箱内设有用于无人机本体上扬声器扩音的扩音设备,所述收纳箱上设有用于收纳扩音设备的收纳机构。本发明通过收纳箱内部设置的扩音设备实现了扩大无人机上附属扬声器音量的效果,并通过环形齿条和遮挡齿轮的相互配合,达到挡板转动闭合隔绝收纳箱的效果,使得收纳箱内部气压在伯努利原理的作用下大于收纳箱周边气压,避免了空气中悬浮的灰尘借助于压强差的作用,进入到收纳箱及从扩音设备内部的现象,解决了因灰尘吸潮对扩音设备造成的损坏,从而提高了对扩音设备的防护。
