Abstract: This application discloses a Bluetooth reconnection method, and relates to the field of short-range wireless communications technologies. The method includes: When a charging case is closed, a first earbud breaks a Bluetooth connection, where the first earbud stores a Bluetooth address of a terminal and a Bluetooth address of a second earbud. When the charging case is opened, the charging case accommodates only the first earbud, and a first preset condition is met, the first earbud sends a first paging request to the second earbud based on the Bluetooth address of the second earbud. The first preset condition is that the Bluetooth connection includes a Bluetooth connection between the first earbud and the second earbud. In this way, reconnection duration of the first earbud when the charging case is opened can be reduced.

Abstract: An audio control system includes a BLUETOOTH headset, a first electronic device, and a second electronic device. The first electronic device sends a first media audio stream to the BLUETOOTH headset in response to a first operation of a user. The BLUETOOTH headset receives the first media audio stream from the first electronic device, and outputs the first media audio stream. The second electronic device outputs, in response to a second operation of the user, a second media audio stream through a first preset channel other than the BLUETOOTH headset. When the BLUETOOTH headset receives the first operation of the user, it performs one of the following actions: interrupting the second BLUETOOTH connection between the BLUETOOTH headset and the second electronic device or sending a first message to the second electronic device indicating that the BLUETOOTH headset is occupied.
