The invention discloses a multi-coupling unmanned aerial vehicle megaphone, which comprises a horn for amplifying sound and a connecting piece for coupling a plurality of sounders to one end of the horn, one end of the connecting piece close to the direction of the horn is a fixed end, the fixed end is provided with a first mounting hole for connecting the horn, and the other end of the connecting piece is a coupling end. The connecting piece is provided with a coupling end for coupling and connecting sounders, the coupling end is obliquely provided with a plurality of centrosymmetric second mounting holes relative to the midpoint of the first mounting hole, and the second mounting holes of the coupling end of the connecting piece are simultaneously coupled and connected with a plurality of sounders. Sound waves transmitted by the sounders are gathered in the connecting piece from the second mounting hole and transmitted into the horn from the second mounting hole to the first mounting hole, the sound waves are amplified through the horn and transmitted to the outside, the sound production power is effectively improved when the multiple sounders synchronously produce sound, the megaphone is high in long-distance sound production efficiency, the size is small, and the sound production efficiency is high. The flexibility of the unmanned aerial vehicle is not influenced.

    本发明公开了一种多耦合无人机喊话器,包括用于扩音的号角和耦合连接若干个发声器至号角一端的连接件,连接件靠近号角方向的一端为固定端,固定端上设有用于连接号角的第一安装孔,连接件的另一端为耦合端,用于耦合连接发声器,耦合端上相对第一安装孔的中点倾斜设有若干个中心对称的第二安装孔,通过设置连接件耦合端的第二安装孔上同时耦合连接若干个发声器,当连接件固定端的第一安装孔固定连接在号角上,发声器输送声波从第二安装孔汇聚在连接件内,从第二安装孔向着第一安装孔的方向传输进入号角内,通过号角对声波放大向外界传声,多个发声器同步发声时有效提高发声功率,使喊话器远距离发声效率高,且体积小,不影响无人机的灵活性。
