In this embodiment, when the earphone device 100 operates, the second processor 21 controls the power management unit 23 to convert the output voltage of the second battery 22 into the working voltage required by the earphone assembly 3, so as to supply power to the earphone assembly 3, and meanwhile, the second processor 21 may monitor the electric quantity of the second battery 22 in real time, and when the electric quantity of the second battery 22 is smaller than a first preset threshold, determine whether the first battery module 1 is online. Wherein the first preset threshold value can be configured or modified by a user.
Preferably, in this embodiment, the determining whether the first battery module 1 is online includes:
monitoring whether an access signal generated when the first battery module 1 is plugged is received in real time in the operation process of the earphone device 100;
if the access signal is received, an online confirmation signal is sent to the first battery module 1, and whether an online signal fed back by the first battery module 1 is received within a preset time is judged;
and if the online signal fed back by the first battery module 1 is received within the preset time and the confirmation times exceed the preset times, judging that the first battery module 1 is online.
In this embodiment, when the first USB interface 16 of the first battery module 1 is inserted into the second USB interface 25 of the second battery module 2, the second detecting unit 24 generates an access signal and sends the access signal to the second processor 21, and when the second processor 21 receives the access signal, the second detecting unit 24 is controlled to send an on-line confirmation signal to the first battery module 1 through the second USB interface 25; when receiving the online confirmation signal, the first battery module 1 detects whether the second battery module 2 is online, and if so, feeds an online signal back to the second battery module 2; if the second battery module 2 receives the on-line signal fed back by the first battery module 1 within the preset time, it indicates that the on-line confirmation is successful, at this time, the second battery module 2 returns to the step of sending the on-line confirmation signal to the first battery module 1, and it is determined that the first battery module 1 is on-line until the confirmation times exceed the preset times. Preferably, in a preferred implementation example, the preset number of times is 3. In the embodiment, as repeated bidirectional confirmation is adopted, the judgment result is more accurate.
Step S302, if the first battery module 1 is on-line, sending an electric quantity request signal to the first battery module 1; the electric quantity request signal is used for triggering the first battery module 1 to supplement the electric quantity to the second battery module 2.
In this embodiment, if the second processor 21 determines that the first battery module 1 is online, the power management chip is controlled to send a power request signal to the first battery module 1 through the second USB interface 25, the first battery module 1 receives the power request signal through the first USB interface 16, and passes the circuit request signal to the first processor 11 via the first detection unit 15, the first processor 11 controls the discharging unit 14 to enter a discharging state after receiving the power amount request signal, the second battery module 2 is charged with the electric quantity through the first USB interface 16, and the second battery module 2 receives the charged electric quantity through the second USB interface 25 and converts the charged electric quantity into the voltage required by charging the second battery 22 through the power management unit 23, so as to charge the second battery 22.

Step S402, if the first battery module 1 is on-line, sending an electric quantity request signal to the first battery module 1; the electric quantity request signal is used for triggering the first battery module 1 to supplement the electric quantity to the second battery module 2.
It should be noted that, since the implementation manners of the step S401 to the step S402 are completely the same as the implementation manners of the step S301 to the step S302 in the previous embodiment, the detailed description thereof is omitted.
Compared with the previous embodiment, in the present embodiment, a bluetooth connection is also established between the first battery module 1 and the second battery module 2. The step S402 is followed by:
step S403, monitoring whether the first battery module 1 is offline.
In this embodiment, the monitoring whether the first battery module 1 is offline specifically includes:
monitoring whether a pulling-out signal generated when the first battery module 1 is pulled out is received;
if the pulling-out signal is received, sending an offline confirmation signal to the first battery module 1, and judging whether an offline signal fed back by the first battery module 1 is received within a preset time;
and if the offline signal fed back by the first battery module 1 is received within the preset time and the confirmation times exceed the preset times, determining that the first battery module 1 is offline.
In this embodiment, when the first USB interface 16 of the first battery module 1 is pulled out from the second USB interface 25 of the second battery module 2, the second detecting unit 24 generates a pull-out signal and sends the pull-out signal to the second processor 21, and when the second processor 21 receives the pull-out signal, the second processor sends an offline confirmation signal to the first battery module 1 through bluetooth; when the first battery module 1 receives the offline confirmation signal through bluetooth, the first processor 11 is triggered to detect whether the second battery module 2 is offline, and if the offline confirmation signal is offline, an offline signal is fed back to the second battery module 2 through bluetooth; if the second battery module 2 receives the offline signal fed back by the first battery module 1 within the preset time, it indicates that the offline is successfully confirmed, at this time, the second battery module 2 returns to the step of sending the offline confirmation signal to the first battery module 1 through bluetooth, and it is determined that the first battery module 1 is offline until the confirmation times exceed the preset times. Preferably, in a preferred implementation example, the preset number of times is 3. In the embodiment, as repeated bidirectional confirmation is adopted, the judgment result is more accurate.
Step S404, if the first battery module 1 is off-line, sending a power ending request signal to the first battery module 1 through Bluetooth connection; the electric quantity ending request signal is used for triggering the first battery module 1 to switch from a discharging state to a charging state.
In this embodiment, when the second processor 21 of the second battery module 2 detects that the first battery module 1 is offline, the power management unit 23 is controlled to send a power request ending signal to the first battery module 1 through bluetooth, so that the first battery module 1 stops discharging to the outside, thereby avoiding unnecessary waste of power in the first battery module 1.
Preferably, in this embodiment, after step S401, the method further includes:
if first battery module 1 off-line, then output low power alarm information.
In this embodiment, the second battery module 2 further includes an alarm device electrically connected to the second processor 21. In the operation process of the earphone device 100, if the electric quantity of the second battery module 2 is smaller than a first preset threshold value, the second processor 21 of the second battery module 2 detects that the first battery module 1 is offline, then the second processor 21 controls the alarm device to output low-electric-quantity alarm information so as to prompt a user to charge the second battery module 2 in time. The alarm devices include, but are not limited to, voice and/or LED light alarm devices.
