Referring to fig. 1, fig. 1 is a flowchart of an audio playback switching method provided in an embodiment of the present invention, where the method is applied to a bluetooth speaker, where the bluetooth speaker includes an audio data unit and a charging output interface for a bluetooth headset, and the audio data unit is used to store audio data and/or obtain audio data from outside the bluetooth speaker, and the method includes:
step S101: when the bluetooth speaker uses itself as the audio playing main body of the audio data unit, the bluetooth speaker determines whether a charging output interface of the bluetooth speaker and a charging input interface of a bluetooth headset are switched from an on state to an off state, if so, step S102 is executed, wherein the charging output interface and the charging input interface are used for realizing that the bluetooth speaker charges the bluetooth headset;
in this embodiment, the bluetooth headset may be a TWS bluetooth headset, and the state between the charging output interface of the bluetooth speaker and the charging input interface of the bluetooth headset may be determined by determining whether there is communication signal transmission between the bluetooth speaker and the bluetooth headset, that is, for the bluetooth speaker, if it is determined that the bluetooth speaker receives a communication signal (such as a serial port signal) sent by the bluetooth headset, it is determined that the charging output interface of the bluetooth speaker and the charging input interface of the bluetooth headset are in a connected state;

when the charging output interface of the Bluetooth sound box and the charging input interface of the Bluetooth headset are in a connected state, the Bluetooth sound box receives the Bluetooth address of the Bluetooth headset, which is sent by the Bluetooth headset, through the charging output interface.
In addition, in the invention, other modes can also be adopted to pre-store the Bluetooth address of the Bluetooth sound box in the Bluetooth headset, and the Bluetooth address of the Bluetooth headset is pre-stored in the Bluetooth sound box.

in addition, it should be noted that, when the bluetooth speaker uses the bluetooth headset as the audio playing main body of the audio data unit, the bluetooth speaker may output a bluetooth audio signal to the bluetooth headset (for example, the bluetooth headset is playing audio data from the audio data unit), or the bluetooth speaker may still use the bluetooth headset as the audio playing main body of the audio data unit without playing audio currently (for example, when the audio is paused, the bluetooth speaker records information that the bluetooth headset is currently used as the audio playing main body of the audio data unit);
step S202: the Bluetooth sound box takes the Bluetooth sound box as an audio playing main body of the audio data unit.
According to the audio playing switching method provided by the embodiment of the invention, the audio playing main body is controlled by utilizing the connection state between the charging output interface of the Bluetooth sound box and the charging input interface of the Bluetooth earphone, so that the automatic switching of the audio playing main body can be realized, and the user experience can be improved.

Preferably, when the bluetooth speaker uses itself as the audio playing main body of the audio data unit, the bluetooth speaker may turn off its bluetooth communication function, so as to reduce energy consumption of the bluetooth speaker, for example, in an embodiment, the step S202 further includes: and the Bluetooth sound box closes the Bluetooth communication function of the Bluetooth sound box.
In an embodiment of the present invention, in order to facilitate the bluetooth speaker and the bluetooth headset to establish a bluetooth communication connection, the bluetooth speaker may store a bluetooth address of the bluetooth headset in advance, and preferably, the bluetooth speaker and the bluetooth headset may automatically backup a bluetooth address of an opposite party from each other through the charging output interface and the charging input interface, that is, the method may further include:

if the Bluetooth sound box judges that the Bluetooth sound box receives a serial port signal sent by a Bluetooth headset, the charging output interface of the Bluetooth sound box and the charging input interface of the Bluetooth headset are in a connected state;
step S202: the Bluetooth sound box takes the Bluetooth sound box as an audio playing main body of the audio data unit and the Bluetooth sound box closes the Bluetooth communication function of the Bluetooth sound box;
when the charging output interface of the Bluetooth sound box and the charging input interface of the Bluetooth headset are in a connected state, the Bluetooth sound box receives the Bluetooth address of the Bluetooth headset, which is sent by the Bluetooth headset, through the charging output interface.
3. A bluetooth speaker, comprising a processor, a memory coupled to the processor, an audio data unit for storing audio data and/or retrieving audio data from outside the bluetooth speaker, and a charging output interface for a bluetooth headset, wherein the memory stores instructions for execution by the processor, and wherein the instructions, when executed by the processor, enable the method of any one of claims 1-2.
4. The bluetooth speaker of claim 3, wherein the audio data unit comprises at least one of a memory, a USB interface, a WIFI communication component, a cellular mobile communication component.
5. A Bluetooth audio playback device, comprising the Bluetooth speaker of claim 3 or 4 and the Bluetooth headset, wherein the Bluetooth headset has a charging input interface that mates with a charging output interface of the Bluetooth speaker.
6. The device of claim 5, wherein the Bluetooth headset is configured to: when the charging input interface of the Bluetooth loudspeaker box is in an on state, the Bluetooth communication function of the Bluetooth loudspeaker box is controlled to be in an off state, and when the charging input interface of the Bluetooth loudspeaker box is in an off state, the Bluetooth communication function of the Bluetooth loudspeaker box is controlled to be in an on state.
