Operation mode switch of wireless headphones
First Claim
1. A wireless audio system, comprising:
- a first wireless headphone 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 about a BLUETOOTH upper layer protocol and 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; and
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.

Abstract
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.

12. A method for wirelessly communicating audio information, comprising:
-
establishing, by a first wireless headphone, a first short-range wireless link with an audio source and a second short-range wireless link with a second wireless headphone; establishing, by the second wireless headphone, a third short-range wireless link with the audio source based on link information associated with the first short-range wireless link for snooping audio information transmitted by the audio source over the first short-range wireless link; transmitting, by the first wireless headphone, a first global acknowledgement (ACK) message indicative of whether the first wireless headphone and the second wireless headphone successfully receive the audio information to the audio source over the first short-range wireless link; in response to a mode switch event, transmitting, by the first wireless headphone, status information about a BLUETOOTH upper layer protocol and associated with the first short-range wireless link to the second wireless headphone over the second short-range wireless link; receiving, by the second wireless headphone, the status information from the first wireless headphone over the second short-range wireless link; in response to the second wireless headphone successfully receiving the status information, transmitting, by the first wireless headphone, a switch start message to the second wireless headphone over the second short-range wireless link to switch modes of the first and second wireless headphones; receiving, by the second wireless headphone, the switch start message from the first wireless headphone over the second short-range wireless link; after transmitting the switch start message, transmitting, by the first wireless headphone, a first local ACK message indicative of whether the first wireless headphone successfully snoops the audio information to the second wireless headphone over the second short-range wireless link; after receiving the switch start message, receiving, by the second wireless headphone, the first local ACK message from the first wireless headphone over the second short-range wireless link; and transmitting, by the second wireless headphone, 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 to the audio source over the third short-range wireless link based on the status information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
