Wireless audio systems and methods for wirelessly communicating audio information are provided. The wireless audio system includes a first wireless transceiver and a second wireless transceiver. The first wireless transceiver includes a first communication module, a first codec, and a second communication module. The first communication module is configured to receive, from an audio source, first audio information. The first codec includes a first decoder configured to obtain second audio information by decoding the first audio information, and a first encoder configured to obtain third audio information by encoding the second audio information. The second communication module is configured to send the third audio information out. The second wireless transceiver includes a third communication module configured to receive the third audio information from the first wireless transceiver. The first communication module employs Classic Bluetooth, and the second communication module and the third communication module employ Low Energy (LE) Audio.

Wireless audio system and method for wirelessly communicating audio information

Embodiments of wireless audio systems and methods for operation mode switch of wireless headphones are disclosed herein. In one example, a wireless audio system includes a first wireless headphone and a second wireless headphone. The first wireless headphone is configured to establish a first short-range wireless link with an audio source; transmit, to a second wireless headphone, link information associated with the first short-range wireless link; and remove the first short-range wireless link with the audio source in response to the second wireless headphone successfully establishing a second short-range wireless link with the audio source based on the link information. The second wireless headphone is configured to receive, from the first wireless headphone, the link information associated with the first short-range wireless link; and establish the second short-range wireless link with the audio source based on the link information.

Operation mode switch of wireless headphones

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 wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a first and a second wireless headphones. The first wireless headphone is configured to receive, from an audio source, audio information using a short-range wireless communication, and in response to successfully receiving the audio information from the audio source, transmit a first error correcting message including an error correcting code generated based on the audio information to a second wireless headphone. The second wireless headphone is configured to receive the audio information from the audio source using the short-range wireless communication, attempt to correct the received audio information based on the first error correcting message, and determine that the received audio information fails to be corrected. In response to the determination, the first wireless headphone is further configured to transmit a second error correcting message including the received audio information to the second wireless headphone.

Wireless audio system and method for wirelessly communicating audio information using the same

Embodiments of wireless audio systems, wireless transceivers, and methods for wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a primary wireless transceiver and a secondary wireless transceiver. The primary wireless transceiver includes a first radio frequency (RF) module configured to transmit, audio information at a first frequency. The primary wireless audio transceiver further includes a second RF module configured to transmit the audio information at a second frequency. The secondary wireless audio transceiver includes a third RF module configured to receive, the audio information at the first frequency. The secondary wireless transceiver further includes a fourth RF module configured to receive the audio information at the second frequency. At least one of the primary wireless audio transceiver or the secondary wireless audio transceiver includes a control module configured to determine a criterion corresponding to switching a transmission frequency from the first frequency to the second frequency is met. The control model is further configured to switch the transmission frequency.

Wireless audio transceivers

Embodiments of wireless audio systems and methods for wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a first wireless headphone and a second wireless headphone. The first wireless headphone is configured to establish a first short-range wireless link with an audio source and a second short-range wireless link with a second wireless headphone; transmit, to the audio source over the first short-range wireless link, a first global acknowledgement (ACK) message indicative of whether the first wireless headphone and the second wireless headphone successfully receive audio information transmitted by the audio source; in response to a mode switch event, transmit, to the second wireless headphone over the second short-range wireless link, status information associated with the first short-range wireless link; in response to the second wireless headphone successfully receiving the status information, transmit, to the second wireless headphone over the second short-range wireless link, a switch start message to switch modes of the first and second wireless headphones; and after transmitting the switch start message, transmit, to the second wireless headphone over the second short-range wireless link, a first local ACK message indicative of whether the first wireless headphone successfully snoops the audio information. The second wireless headphone configured to establish a third short-range wireless link with the audio source based on link information associated with the first short-range wireless link for snooping the audio information transmitted over the first short-range wireless link; receive, from the first wireless headphone over the second short-range wireless link, the status information; receive, from the first wireless headphone over the second short-range wireless link, the switch start message; after receiving the switch start message, receive, from the first wireless headphone over the second short-range wireless link, the first local ACK message; and transmit, to the audio source over the third short-range wireless link based on the status information, a second global ACK message indicative of whether the first wireless headphone and the second wireless headphone successfully receive the audio information based on the first local ACK message.
