Step S140, obtaining a second battery capacity value according to the terminated battery voltage value in the preset battery voltage relation table.
In one embodiment, referring to fig. 3, obtaining the preset charge-voltage relationship table includes, but is not limited to, the following steps:
step S310, obtaining the working average current of the earphone.
In an embodiment, the working average current of the earphone may be a statistical value, that is, the working average current is obtained by performing statistical averaging on the working current for a period of time, for example, the working average current is obtained by calculating through the steps in the following embodiments:
step S311, selecting test audio.
In one embodiment, a plurality of different types of audio may be selected as test audio, and a related test audio database may be established, from which one or more related test audio may be selected as desired.
Step S312, play the test audio within the preset test time.
In an embodiment, in order to obtain the working average current of the earphone through statistics, after the test audio is selected, playing the selected test audio within a preset test time, and if more than one test audio exists, storing playing process data of each test audio.

In an embodiment, a change value of earphone current is obtained from playing process data of playing test audio in a preset test time, sampling quantization is performed on the earphone current data, and average is performed to obtain working average current of the earphone. For example, the change value of the earphone current is sampled in units of seconds, and the average value is obtained. It will be appreciated that if more than one test audio is selected, the corresponding earphone working average currents are calculated according to the method of the embodiment, and the obtained working average currents are averaged again to be used as the working average currents for detecting the battery power of the earphone.
Step S320, discharging the earphone battery according to the working average current.
In an embodiment, the working average current obtained by statistics in step S310 is used to perform a discharging operation on the earphone battery, which can avoid errors caused by fluctuation of the working current due to various factors.
Step S330, record the first relation between the battery power change and the voltage change of the earphone during the discharging operation.
In an embodiment, the change of the battery power and the change of the voltage of the earphone are recorded during the whole discharging operation from the beginning of discharging to the end of discharging, so as to obtain a first relation curve about the change of the battery power and the change of the voltage of the earphone.
Step S340, quantifying the first relation curve to obtain a preset electric quantity voltage relation table.
In an embodiment, the obtained first relation curve is sampled and quantized according to the required quantization precision, for example, the voltage of the first relation curve is sampled with 0.01V as the quantization precision, the corresponding earphone battery electric quantity is obtained, the quantization relation between the first relation curve and the second relation curve is expressed in a form of a preset electric quantity voltage relation table, and the relation between the earphone battery electric quantity and the voltage change obtained in the mode is closest to real measurement data.
In one embodiment, the preset electric quantity voltage relation table may be represented as [ V1-C1, V2-C2, …, vn-Cn ], where the voltage is represented by V, the battery electric quantity is represented by C, and the electric quantity of the battery is measured by directly looking up a table in the subsequent process, so as to improve the efficiency of detecting the electric quantity of the battery.
After the preset electric quantity voltage relation table is obtained in the above embodiment, the first battery capacity value is obtained by looking up a table according to the initial battery voltage value, or the second battery capacity value is obtained by looking up a table according to the final battery voltage value.
In addition, it can be understood that the corresponding first battery capacity value is obtained in the preset electric quantity voltage relation table according to the initial battery voltage value, or the corresponding second battery capacity value is obtained in the preset electric quantity voltage relation table according to the final battery voltage value, and if the preset electric quantity voltage relation table does not have a completely consistent corresponding relation, the closest corresponding relation is selected.
For example, in step S130, if a corresponding first battery capacity value is required to be obtained from the preset battery capacity voltage relation table according to the initial battery voltage value, for example, the initial battery voltage value is 0.36V, but the corresponding relation between the battery capacity and the voltage in the preset battery capacity voltage relation table is: 0.3-200mAh and 0.4-300mAh, the first battery capacity value corresponding to the initial battery voltage value is 300mAh according to the closest corresponding relation, which is only shown and not specifically limited.

in step S410, the earphone battery is charged.
Step S420, recording a second relationship between battery charge change and charge time change in the battery during the charging operation.
In an embodiment, due to the internal characteristics of the lithium battery, the battery voltage is fast flown when the wireless earphone is charged, so that the earphone battery can generate a virtual electricity phenomenon when being charged, namely, the displayed battery electric quantity is very high, the actual battery electric quantity is relatively low, especially when the earphone is just charged, the voltage of the earphone battery is detected to have a virtual high phenomenon when in a charging state, and the voltage virtual high phenomenon can also occur in a certain time when the charging is stopped, so that the difference between the battery electric quantity value and the battery electric quantity true value is larger. Therefore, in this embodiment, in the process of charging the earphone battery from the start of charging to the end of charging (for example, by the battery power not changing steadily for a preset change time as a sign) in a state where the battery power of the earphone battery is 0 or near 0, the change of the battery power of the earphone battery and the change of the charging time are recorded, so as to obtain the second relationship curve between the two.
Step S430, quantifying the second relation curve to obtain a preset electric quantity charging time relation table.
In an embodiment, the obtained second relation curve is sampled and quantized according to the required quantization precision, for example, 1s is used as the quantization precision, the charging time of the second relation curve is sampled to obtain the corresponding battery capacity of the earphone, the quantization relation between the two is represented as a form of a preset electric quantity charging time relation table, and the form of the preset electric quantity charging time relation table is prestored, for example, the preset electric quantity charging time relation table can be represented as [ T1-C1, T2-C2, …, tn-Cn ], wherein the charging time is represented by T, the battery capacity is represented by C, and the battery capacity is directly checked when the battery capacity is measured later, so that the efficiency of detecting the battery capacity is improved.
It can be understood that the obtained first relationship curve or the second relationship curve is sampled and quantized according to a required quantization precision, wherein the quantization precision can also be calculated according to the electric quantity of the earphone battery, for example, the electric quantity of the earphone battery is changed by 1%, and 1% of the total electric quantity of the earphone battery is used as the quantization precision.
In one embodiment, referring to fig. 5, step S150 includes, but is not limited to, the following steps:
step S510, calculating the charging time according to the charging start time and the charging end time.
In one embodiment, the charging time is the difference between the charging end time and the charging start time.
Step S520, a first charging time is obtained according to the first battery capacity value in the preset charge time table.
In an embodiment, the first battery capacity value is checked in a preset electric quantity charging time relation table to obtain the first charging time, and similarly, if the preset electric quantity charging time relation table does not have a completely consistent corresponding relation, the closest corresponding relation is selected.
In step S530, a second charging time is obtained according to the charging time and the first charging time.
In one embodiment, the charging time and the first charging time are summed to obtain a second charging time.
Step S540, a third battery capacity value is obtained according to the second charging time in the preset electric quantity charging time relation table.
