另外,控制终端在用户录制声音结束后,确定音频文件,然后向无人机发送该音频文件,无人机再控制扬声器播放该音频文件。或者,
控制终端在用户边录制声音的同时,实时确定音频文件并将实时确定的音频文件发送给无人机。无人机可以在接收该音频文件的同时,实时控制扬声器播放接收的音频文件,实现用户的声音录制与无人机机载的扬声器的播放尽可能同步;或者,无人机可以接收控制终端发送的音频文件,并在接收音频文件完毕后,再播放接收的音频文件。
在一实现方式中,控制终端发送给无人机的音频文件为编码后的音频文件,由于编码后的音频文件的文件大小会减少,从而可以节省控制终端与无人机之间的传输资源。具体地,用户对控制终端执行音频输入操作,控制终端检测到该音频输入操作,并根据音频输入操作,获得音频信息,再对音频信息进行编码,获得编码后的音频文件。然后控制终端将编码后的音频文件发送给无人机。无人机获取控制终端发送的编码后的音频文件,由于该音频文件为编码获得的音频文件,无人机再对该音频文件进行解码,获得解码后的音频文件,然后控制扬声器播放该解码后的音频文件。
综上所述,本发明实施例中,用户可以通过操作控制终端以控制无人机机载的扬声器播放音频,例如用户可以控制扬声器播放无人机中本地存储的音频文件,也可以控制扬声器通过音频来播放用户输入的文字信息的内容,也可以控制扬声器播放用户录制的声音。因此,用户通过操作控制终端即可在无人机飞行过程中实时控制无人机机载的扬声器播放音频,通过无人机来进行音频播放,可适应各种不同的播放音频应用场景,为用户带来了无人机播放音频的控制体验。
