Abstract

Claims (50)

1. A data receiving method for Bluetooth earbuds, comprising:

transmitting, by a master earbud of the Bluetooth earbuds, connection parameter information of a first wireless link between the master earbud and an audio source device to a slave earbud of the Bluetooth earbuds;

receiving, by the master earbud through the first wireless link, first audio data from the audio source device;

obtaining the first audio data by monitoring the first wireless link, by the slave earbud based on the connection parameter information; and

transmitting an acknowledgement message to the audio source device by the master earbud, in response to not receiving a feedback from the slave earbud in a predetermined time period after receiving the first audio data, so as to notify the audio source device to transmit second audio data.

2. The method according to claim 1 , wherein the feedback comprises negative feedback information indicating that the slave earbud fails to receive the first audio data; and the method further comprises:

transmitting the negative feedback information to the master earbud by the slave earbud, in response to the slave earbud failing to obtain the first audio data.

3. The method according to claim 2 , further comprising:

transmitting a negative acknowledgement message to the audio source device by the master earbud in response to receiving the negative feedback information from the slave earbud in the predetermined time period, to notify the audio source device to retransmit the first audio data.

4. The method according to claim 1 , wherein the feedback comprises positive feedback information, and wherein the method further comprises:

not transmitting the positive feedback information to the master earbud by the slave earbud, in response to the slave earbud obtaining the first audio data, the positive feedback information indicating that the slave earbud has received the first audio data.

5. The method according to claim 1 , further comprising:

not transmitting feedback information to the master earbud by the slave earbud, in response to the slave earbud failing to obtain the first audio data.

6. The method according to claim 1 , wherein the feedback comprises positive feedback information indicating that the slave earbud has received the first audio data; and the method further comprises:

transmitting the positive feedback information to the master earbud by the slave earbud, in response to the slave earbud obtaining the first audio data.

7. The method according to claim 6 , further comprising:

transmitting the acknowledgement message to the audio source device by the master earbud in response to receiving the first audio data and receiving the positive feedback information from the slave earbud, to notify the audio source device to transmit the second audio data.

8. The method according to claim 1 , further comprising:

transmitting a negative acknowledgement message to the audio source device by the master earbud in response to the master earbud failing to receive the first audio data, to notify the audio source device to retransmit the first audio data.

9. The method according to claim 1 , further comprising, prior to said transmitting, by the master earbud of the Bluetooth earbuds, the connection parameter information of the first wireless link between the master earbud and the audio source device to the slave earbud of the Bluetooth earbuds:

establishing a first wireless connection between the master earbud and the audio source device to form the first wireless link; and

establishing a second wireless connection between the master earbud and the slave earbud to form a second wireless link.

10. The method according to claim 9 , wherein said transmitting, by the master earbud of the Bluetooth earbuds, the connection parameter information of the first wireless link between the master earbud and the audio source device to the slave earbud of the Bluetooth earbuds comprises:

transmitting, by the master earbud through the second wireless link, the connection parameter information of the first wireless link to the slave earbud.

11. The method according to claim 9 , further comprising:

detecting, by the master earbud, whether feedback transmitted from the slave earbud has been received through the second wireless link.

12. The method according to claim 9 , wherein the predetermined time period is shorter than or equal to a time length of a receiving time slot of the second wireless link.

13. Bluetooth earbuds, comprising:

one or more processors; and

memory configured to store instructions which, when executed by the one or more processors, cause the one or more processors to:

transmit, by a master earbud of the Bluetooth earbuds, connection parameter information of a first wireless link between the master earbud and an audio source device to a slave earbud of the Bluetooth earbuds;

receive, by the master earbud through the first wireless link, first audio data transmitted from the audio source device;

monitor, by the slave earbud based on the connection parameter information, the first wireless link to obtain the first audio data; and

transmit an acknowledgement message to the audio source device by the master earbud, in response to not receiving a feedback from the slave earbud in a predetermined time period after receiving the first audio data, so as to notify the audio source device to transmit second audio data.

14. The Bluetooth earbuds according to claim 13 , wherein the feedback comprises negative feedback information indicating that the slave earbud fails to receive the first audio data, the instructions further cause the one or more processors to:

transmit the negative feedback information to the master earbud by the slave earbud, in response to the slave earbud failing to obtain the first audio data.

15. The Bluetooth earbuds according to claim 14 , the instructions further cause the one or more processors to: transmit a negative acknowledgement message to the audio source device by the master earbud, in response to the master earbud receiving the negative feedback information from the slave earbud in the predetermined time period, so as to notify the audio source device to retransmit the first audio data.

16. The Bluetooth earbuds according to claim 13 , wherein the feedback comprises positive feedback information, and the instructions further cause the one or more processors to:

not transmit the positive feedback information to the master earbud by the slave earbud, in response to the slave earbud obtaining the first audio data, the positive feedback information indicating that the slave earbud has received the first audio data.

17. The Bluetooth earbuds according to claim 13 , the instructions further cause the one or more processors to:

not transmit feedback information to the master earbud by the slave earbud, in response to the slave earbud failing to obtain the first audio data.

18. The Bluetooth earbuds according to claim 13 , wherein the feedback comprises positive feedback information indicating that the slave earbud has received the first audio data; and the instructions further cause the one or more processors to:

transmit the positive feedback information to the master earbud by the slave earbud, in response to the slave earbud obtaining the first audio data.

19. The Bluetooth earbuds according to claim 13 , the instructions further cause the one or more processors to:

transmit a negative acknowledgement message to the audio source device by the master earbud in response to the master earbud failing to receive the first audio data, so as to notify the audio source device to retransmit the first audio data.

20. A non-transitory computer-readable storage medium, having a computer program stored thereon, wherein the computer program, when executed by a processor, implements:

transmitting, by a master earbud of the Bluetooth earbuds, connection parameter information of a first wireless link between the master earbud and an audio source device to a slave earbud of the Bluetooth earbuds;

receiving, by the master earbud through the first wireless link, first audio data transmitted from the audio source device;

obtaining the first audio data by monitoring the first wireless link, by the slave earbud based on the connection parameter information; and

transmitting an acknowledgement message to the audio source device by the master earbud, in response to not receiving a feedback from the slave earbud in a predetermined time period after receiving the first audio data, so as to notify the audio source device to transmit second audio data.
