The invention relates to a USB audio playing method and device of a vehicle, electronic equipment and a storage medium, the vehicle is provided with USB equipment, an audio switching module is arranged between connecting lines of the USB equipment, the transmission control protocol of the USB equipment is a USB HID protocol, and the method comprises the steps that it is judged that the audio switching module receives to-be-played audio data output by a mobile terminal, a playing control instruction generated by audio data to be played is sent to an audio control module through a USB HID protocol so as to control an audio acquisition module and a forwarding module in an audio DSP to enter a preparation state, and meanwhile, an audio focus is applied; and after the audio DSP receives the audio data to be played, the audio data to be played is input to the DSP audio mixing module through the audio forwarding module, so that the audio data to be played and preset media audio are mixed and then output to a media channel of the power amplifier for output. Therefore, the problem of audio and video playing delay is solved, audio and video playing lagging is avoided, and the user experience is improved.

    本申请涉及一种车辆的USB音频播放方法、装置、电子设备及存储介质,车辆设有USB设备,其连接线间设有音频转接模块,USB设备的传输控制协议为USB HID协议,方法包括:判断音频转接模块接收到移动终端输出的待播放音频数据,通过USB HID协议发送由待播放音频数据生成的播放控制指令至音频控制模块,以控制音频DSP内音频采集模块及转发模块进入准备状态,同时申请音频焦点;在音频DSP接收到待播放音频数据后,通过音频转发模块将待播放音频数据输入到DSP混音模块,以将待播放音频数据和预设的媒体音混音后输出到功放的媒体通道进行输出。由此,解决音视频播放延迟的问题,避免音视频播放卡顿,提升用户体验。
