  • Audio concealment method and wireless audio output device using the same
    Patent number: 11172303
    Abstract: A wireless audio output device including a first audio output unit and a second audio output unit is provided. The wireless audio output device establishes a wireless link with an audio source, which outputs a first original audio data and a second original audio data. The first and the second audio output units simultaneously output and play the first and the second original audio data. When the first audio output unit successfully receives the first original audio data but the second audio output unit fails to receive the second original audio data, the first audio output unit drops the received first original audio data, and the first and the second audio output units generate a first concealment audio data and a second concealment audio data, respectively, by using a PLC algorithm and play the first concealment audio data and the second concealment audio data, respectively.
