1. A UWB-based low-delay lossless digital audio transmission unit, comprising an audio input module, an audio processing module, a radio frequency transceiving module and a UWB processing module, wherein
the audio input module is configured to input an audio signal, to convert the audio signal into a first digital audio signal in I2S format, and to output the first digital audio signal;
the audio processing module is in signal connection with the audio input module, and is configured to receive the first digital audio signal in I2S format output by the audio input module, to process the first digital audio signal and to transmit the processed first digital audio signal to the UWB processing module;
the UWB processing module is in signal connection with both the audio processing module and the radio frequency transceiving module simultaneously, and is configured to process the first digital audio signal received from the audio processing module and a second digital audio signal received from the radio frequency transceiving module;
the radio frequency transceiving module is further in signal connection with another digital audio transmission unit, and is configured to send, to the another digital audio transmission unit, the first digital audio signal processed by the UWB processing module, and further configured to receive the second digital audio signal in I2S format sent by the another digital audio transmission unit to the UWB processing module.
