Then, the driving mechanism may drive the first movable member <NUM> and the second movable member <NUM> to move to cause the second movable member <NUM> receiving the third body to move below the first body <NUM> of the wireless earphone <NUM>. In this case, the first movable member <NUM> and the second movable member <NUM> are in the second state. Since the structures of the third body and the second body <NUM> are exactly the same, the sixth contact <NUM> in the second receiving chamber positively energizes the fifth contact on the third body, so that the second magnetic member on the third body and the first magnetic member <NUM> on the first body <NUM> have opposite polarities attracting each other, then the third body is connected to the first body <NUM>, and an earphone circuit of the wireless earphone <NUM> begins to be powered by the second battery.

Then, the removed second body <NUM> is left in the wireless earphone box <NUM>. The charge circuit in the wireless earphone box <NUM> may charge the second body <NUM>. When electric power of the second battery in the third body is low, the third body may be removed in the same manner to replace the fully charged second body <NUM>, and the wireless earphone box <NUM> continues charging the second battery of the third body.

In an implementation, the wireless earphone box <NUM> may include a second control module. When the wireless earphone box <NUM> detects that the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are separated, the second control module may control the driving mechanism to drive the first movable member <NUM> and the second movable member <NUM> to move. Alternatively, the wireless earphone box <NUM> may be provided with a second control button. When the second control button is pressed, the second control module is started. Alternatively, the wireless earphone box <NUM> may be provided with a second delay apparatus, and after the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are separated, the second control module is automatically started after a preset time of delay. No limitation is made herein.

After the second body <NUM> including the first battery <NUM> is removed from the wireless earphone <NUM>, through the driving of the driving mechanism, the third body including the second battery may be automatically mounted without user manual operations, so that the wireless earphone <NUM> automatically replaces the battery. At the same time, the replacement of the second battery and the first battery can ensure continuous and sufficient electric power of the wireless earphone <NUM>, and the users do not need to spend time waiting for the wireless earphone <NUM> to be charged, which improves user experience.

Further, as shown in <FIG>, the first movable member <NUM> includes a first connecting member <NUM> and a second connecting member <NUM>, the first connecting member <NUM> is provided with a third receiving chamber, the second connecting member <NUM> is provided with the first receiving chamber, the third receiving chamber is configured to receive the first body <NUM> of the wireless earphone <NUM>, and the first receiving chamber is configured to receive the second body <NUM>.

The driving mechanism is connected to the second connecting member <NUM> and the second movable member <NUM>. In a case that the second body <NUM> is received in the first receiving chamber, the driving mechanism is configured to drive the second connecting member <NUM> and the second movable member <NUM> to switch between a first state and a second state.

In this embodiment, as shown in <FIG>, the first movable member <NUM> includes the first connecting member <NUM> and the second connecting member <NUM>, and both the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> may be received in the first movable member <NUM>. The second connecting member <NUM> and the second movable member <NUM> are at a same level height, and structures of the second connecting member <NUM> and the second movable member <NUM> may be exactly the same.

In an implementation, the second connecting member <NUM> and the second movable member <NUM> may also be provided in the wireless earphone box <NUM> according to the top views shown in <FIG>. A1 and A2 are the second connecting members <NUM>, and B <NUM> and B2 are the second movable members <NUM>.

In this embodiment, the first connecting member <NUM> may be understood as being fixed to the wireless earphone box <NUM>. When the wireless earphone <NUM> is received in the first movable member <NUM>, the driving mechanism may drive the second connecting member <NUM> and the second movable member <NUM> to switch between the first state and the second state, while a position of the first connecting member <NUM> may not change.

Specifically, when the second connecting member <NUM> and the second movable member <NUM> are in the first state, the second connecting member <NUM> is located below the first connecting member <NUM>, the third receiving chamber is communicated with the first receiving chamber, the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are connected, the fourth contact <NUM> in the first receiving chamber reversely energizes the third contact <NUM> of the second body <NUM>, and the second body <NUM> and the first body <NUM> of the wireless earphone <NUM> are separated, to realize removal of the second body <NUM> including the first battery <NUM>.

The sixth contact <NUM> in the second receiving chamber positively energizes the fifth contact on the third body, so that the third body is connected to the first body <NUM>, and an earphone circuit of the wireless earphone <NUM> begins to be powered by the second battery.

In this embodiment, when the battery in the wireless earphone <NUM> needs to be replaced, the wireless earphone <NUM> is entirely put in the wireless earphone box <NUM>, the first body <NUM> of the wireless earphone <NUM> is fixed through the first connecting member <NUM>, the driving mechanism drives the second connecting member <NUM> and the second movable member <NUM> to move, and then the second body <NUM> and the third body are swapped, so that the first body <NUM> of the wireless earphone <NUM> is connected to the third body to complete replacement of the battery of the wireless earphone <NUM> without user intervention, which further improves automation of the replacement of the battery of the wireless earphone <NUM>.

Further, as shown in <FIG>, the driving mechanism includes a third magnetic member <NUM> and a fourth magnetic member <NUM>, a first side of the third magnetic member <NUM> is connected to the second connecting member <NUM> and the second movable member <NUM>, the fourth magnetic member <NUM> is fixed to a second side of the third magnetic member <NUM> at intervals, and the first side is opposite the second side.

The fourth magnetic member <NUM> is energized to cause the first connecting member <NUM> and the second connecting member <NUM> to be in a connected state or separated state. In the connected state, the third magnetic member <NUM> and the fourth magnetic member <NUM> have a same polarity repelling each other. In the separated state, the third magnetic member <NUM> and the fourth magnetic member <NUM> have opposite polarities attracting each other.

In this embodiment, the driving mechanism includes the third magnetic member <NUM> and the fourth magnetic member <NUM>. As shown in <FIG>, the fourth magnetic member <NUM> may be fixed and energized to change a polarity. Specifically, when the fourth magnetic member <NUM> is positively energized, the polarity of the fourth magnetic member <NUM> may be the same as that of the third magnetic member <NUM>, the fourth magnetic member <NUM> and the third magnetic member <NUM> repel each other to produce thrust to drive the third magnetic member <NUM> to move the second connecting member <NUM> and the second movable member <NUM> upwards, and the first connecting member <NUM> is connected to the second connecting member <NUM>.

When the fourth magnetic member <NUM> is reversely energized, the polarity of the fourth magnetic member <NUM> may be opposite to that of the third magnetic member <NUM>, the fourth magnetic member <NUM> and the third magnetic member <NUM> attract each other to produce tension to drive the third magnetic member <NUM> to move the second connecting member <NUM> and the second movable member <NUM> downwards, and the first connecting member <NUM> is separated from the second connecting member <NUM>.

In this embodiment, it is a default state of the wireless earphone box <NUM> that the power supply module of the wireless earphone box <NUM> positively energizes the fourth magnetic member <NUM>. After the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are separated, the power supply module of the wireless earphone box <NUM> may be controlled to reversely energize the fourth magnetic member <NUM>, so that the first connecting member <NUM> is separated from the second connecting member <NUM>. Then, the driving mechanism moves the second connecting member <NUM> and the second movable member <NUM> again. When the second connecting member <NUM> and the second movable member <NUM> are in the second state, the power supply module of the wireless earphone box <NUM> is controlled to positively energize the fourth magnetic member <NUM>, so that the first connecting member <NUM> is connected to the second movable member <NUM>.

In this way, during replacement of the second body <NUM> with the third body, the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are separated, and the first connecting member <NUM> and the second connecting member <NUM> are also separated, which prevents high friction resistance between the second connecting member <NUM> and the first connecting member <NUM> caused by movement of the second connecting member <NUM> and the second movable member <NUM> and further improves the efficiency of the replacement of the battery of the wireless earphone <NUM>.

In an implementation, the wireless earphone box <NUM> may include a third control module. When the wireless earphone box <NUM> detects that the first body <NUM> and the second body <NUM> of the wireless earphone <NUM> are separated, the third control module may first control the power supply module to reversely energize the fourth magnetic member <NUM> to separate the first connecting member <NUM> from the second connecting member <NUM> and then control the driving mechanism to be started to drive the second connecting member <NUM> and the second movable member <NUM> to move, which is not limited herein.

Further, as shown in <FIG>, the driving mechanism includes a third connecting member <NUM> and a driving component <NUM>. The driving component <NUM> is connected to the third connecting member <NUM>, the third connecting member <NUM> is connected to the second connecting member <NUM> and the second movable member <NUM>, and the driving component <NUM> may drive the third connecting member <NUM> to rotate to cause the second connecting member <NUM> and the second movable member <NUM> to switch between the first state and the second state.

In an implementation, the third connecting member <NUM> may have a cross structure as shown in <FIG>. The two second connecting members <NUM> (A1 and A2) are connected to a first end and a second end of the third connecting member <NUM> that are disposed opposite, and the two second movable members <NUM> (B1 and B2) are connected to a third end and a fourth end of the third connecting member <NUM> that are disposed opposite.

In an implementation, as shown in <FIG>, the third magnetic member <NUM> may be connected to the third connecting member <NUM>, and the second connecting member <NUM> and the second movable member <NUM> may be driven through the third connecting member <NUM> to move up and down. A specific implementation form may be obtained with reference to the descriptions in the above embodiment.
