  • Patent number: 10397684
    Abstract: Wireless speaker systems and methods for synchronous audio playback. Speaker systems can comprise more than one wireless speaker assembly, such as wireless earphones, in serial communication with an audio source device, such as a smartphone. Separate audio rendering by each wireless speaker assembly and synchronization of audio playback by imposing a fixed latency from an output timestamp associated with the audio source data, and rate matching the sample allow for tightly synchronized playback of stereo audio at low latency.
