Embodiments of systems and methods for transmission of audio information are disclosed herein. In one example, a System on Chip (SoC) includes a wired transceiver module, a wireless module, a Frequency Modulation (FM) demodulation module, and an audio information codec module operatively coupled to the wired transceiver and the FM demodulation module. The wired transceiver module is configured to receive a data packet corresponding to first audio information. The wireless module is configured to receive an FM signal, corresponding to second audio information. The FM demodulation module is configured to output the second audio information based on demodulating the FM signal. The audio information codec module is configured to decode the first audio information and the second audio information based on the data packet and the demodulated FM signal, respectively.

Systems and methods for transmission of audio information

A method realizes synchronous playing of audio data from an audio source by two or more wireless speakers. The method includes receiving at each of the wireless speakers first audio data packets sent by the audio source and determining a respective first time point for the receiving of the first audio data packets; processing the first audio data packets at each of the wireless speakers to generate respective second audio data packets, the second audio data packets each including audio data to be played with a fixed data length; setting a delayed play time and obtaining a playing time point at each of the wireless speakers, the obtaining of the playing time point being based on the respective first time point and the respective delayed play time; and playing the second audio data packets at each of the wireless speakers at the respective playing time point.

Method, device, loudspeaker equipment and wireless headset for playing audio synchronously

Embodiments of wireless audio systems and methods for synchronizing wireless headphones are disclosed herein. In one example, a wireless audio system includes an audio source, a first wireless headphone, and a second wireless headphone. The audio source is configured to separately transmit a left-channel audio signal and a right-channel audio signal using a short-range wireless communication protocol. The first wireless headphone is configured to receive the left-channel audio signal and synchronize a first clock of the first wireless headphone with the audio source based on the left-channel audio signal. The second wireless headphone is configured to receive the right-channel audio signal and synchronize a second clock of the second wireless headphone with the audio source based on the right-channel audio signal, so that the first clock of the first wireless headphone is synchronized with the second clock of the second wireless headphone.
