Un-tethered wireless audio system
A wireless speaker audio system configured to receive audio information wirelessly transmitted by an audio source including first and second wireless transceivers. The first wireless transceiver establishes a bidirectional secondary wireless link with the audio source for receiving and acknowledging receipt of the audio information. The first and second wireless transceivers communicate with each other via a primary wireless link. A wireless audio system including an audio source and first and second wireless transceivers. The first and second wireless transceivers communicate via a primary wireless link. The audio source communicates audio information to the first wireless transceiver via a secondary wireless link which is configured according to a standard wireless protocol. The first wireless transceiver is configured to acknowledge successful reception of audio information via the secondary wireless link. Other embodiments are also described and claimed.
1. A first wireless audio output device, comprising:
a transceiver configured to communicate with a second audio output device via a first wireless link and configured to communicate with an audio source via a second wireless link, wherein the transceiver receives, from the audio source via the second wireless link, a first audio packet; and
a controller configured to determine whether the second audio output device received the first audio packet directly from the audio source,
wherein, when it is determined the second audio output device did not receive the first second audio packet, the transceiver is configured to transmit, to the second audio output device via the first wireless link, the first audio packet.
2. The first wireless audio output device of claim 1 , wherein the controller determines whether the second audio output device received the first audio packet based on at least a first indication received from the second audio output device via the first wireless link.
3. The first wireless audio output device of claim 1 , wherein the controller determines whether the second audio output device received the first audio packet based on at least the first audio output device not receiving an indication from the second audio output device in a slot designated for the indication.
4. The first wireless audio output device of claim 1 , wherein the second wireless link comprises one of a Bluetooth connection, a proprietary protocol connection, a peer-to-peer connection, or a WiFi connection.
5. The first wireless audio output device of claim 1 , wherein the first wireless audio output device comprises a first ear bud and the second wireless audio output device comprises a second ear bud.
6. A method performed by a first wireless audio output device configured to communicate with a second audio output device via a first wireless link and configured to communicate with an audio source via a second wireless link, the method comprising:
receiving, from the audio source via the second wireless link, a first audio packet;
determining whether the second audio output device received the first audio packet directly from the audio source; and
when it is determined the second audio output device did not receive the first second audio packet, transmitting, to the second audio output device via the first wireless link, the first audio packet.
7. The method of claim 6 , wherein determining whether the second audio output device received the first audio packet is based on at least a first indication received from the second audio output device via the first wireless link.
8. The method of claim 6 , wherein determining whether the second audio output device received the first audio packet based on at least the first audio output device not receiving an indication from the second audio output device in a slot designated for the indication.
9. The method of claim 6 , wherein the second wireless link comprises one of a Bluetooth connection, a proprietary protocol connection, a peer-to-peer connection, or a WiFi connection.
10. The method of claim 6 , wherein the first wireless audio output device comprises a first ear bud and the second wireless audio output device comprises a second ear bud.
11. An integrated circuit configured for use in a first wireless audio output device configured to communicate with a second audio output device via a first wireless link and configured to communicate with an audio source via a second wireless link, the integrated circuit comprising:
circuitry configured to receive, from the audio source via the second wireless link, a first audio packet;
circuitry configured to determine whether the second audio output device received the first audio packet directly from the audio source; and
when it is determined the second audio output device did not receive the first second audio packet, circuitry configured to transmit, to the second audio output device via the first wireless link, the first audio packet.
12. The integrated circuit of claim 11 , wherein determining whether the second audio output device received the first audio packet is based on at least a first indication received from the second audio output device via the first wireless link.
13. The integrated circuit of claim 11 , wherein determining whether the second audio output device received the first audio packet based on at least the first audio output device not receiving an indication from the second audio output device in a slot designated for the indication.
14. The integrated circuit of claim 11 , wherein the second wireless link comprises one of a Bluetooth connection, a proprietary protocol connection, a peer-to-peer connection, or a WiFi connection.
15. The integrated circuit of claim 11 , wherein the first wireless audio output device comprises a first ear bud and the second wireless audio output device comprises a second ear bud.
