It should be noted that, in the present embodiment, the charging parameter corresponding to the real-time electric quantity is used to charge the real wireless headset, and it may also be understood that a charging curve corresponding to the real-time electric quantity is used to charge the real wireless headset. The charging curve referred to herein is a curve of a charging parameter of the storage battery, which is obtained during charging of the storage battery under a certain charging condition, as a function of time.
The charging bin provided by the embodiment can be connected with the real wireless earphone through three groups of contacts. The schematic structural diagram of the connection between the charging chamber and the true wireless earphone through three sets of contacts is shown in fig. 2. The first group of contacts in the three groups of contacts is connected with the charging module, so that the charging module can charge the real wireless earphone; the second group of contacts in the three groups of contacts is connected with the control module, so that the control module can obtain the real-time electric quantity of the real wireless earphone; and the third group of contacts in the three groups of contacts is connected with the control module and is used for connecting a ground circuit. Under the condition of connecting through three group's contacts between storehouse and the true wireless earphone that charges, different functions are realized respectively to three group's contacts, and the functional partitioning is more clear, can avoid carrying out the function switch and probably take place the confusion to can guarantee the normal clear of storehouse work that charges.

In this example, the charging unit and the voltage modulation unit are used to respectively realize different functions of the charging module, so that a link of the charging module for processing an electric signal is clearer, and the realization difficulty of the charging module is reduced.
In the above example, the voltage modulation unit may include a buck-boost circuit. The buck-boost circuit is simple in principle and low in price, and is a very common circuit unit in the field of power electronic design. In order to reduce the implementation difficulty of the charging module of the charging bin and reduce the cost, the voltage modulation unit in this embodiment may also include a buck-boost circuit.

The charging bin provided by the embodiment can charge the earphone according to the charging parameters corresponding to the real-time electric quantity of the earphone, can effectively control the loss caused by the earphone battery, and is beneficial to prolonging the service life of the earphone battery. Compared with the charging mode that the charging modules are arranged in the earphone charging bin and the earphone and the charging parameters are adjusted by the charging module in the wireless earphone in the related technology, the wireless earphone charging system can charge the earphone by the charging parameters suitable for the current electric quantity of the earphone only by the charging bin, so that the charging module in the earphone is cancelled. Compared with the related art, the wireless earphone charging device has the advantages that power loss caused by the charging module of the earphone during charging can be reduced, charging efficiency can be improved, and time required for full charging of the wireless earphone can be shortened. In addition, due to the improvement of the charging efficiency and the reduction of the power consumed during charging, when the charging bin adopts batteries with the same capacity, the invention can effectively improve the endurance time of the earphone, thereby further improving the use experience of the real wireless earphone of a user.
