Problems solved by technology

[0004] However, due to the problem of ADC sampling accuracy, when the headphone battery is charging, if the voltage change is small, the ADC may not detect the voltage change, that is, the ADC does not sample accurately when the voltage change is small, for example, the battery voltage rises from 3.76V to When the voltage is 3.8V, the voltage changes only by 40mV. At this time, the ADC may not detect the voltage change, resulting in no change in the displayed battery percentage, but from figure 2 It can be seen that the actual battery percentage has increased significantly (from 16% to 23%) at this time, so the battery percentage display is not accurate at this time

Abstract

The invention provides a method of establishing a corresponding relation between an earphone battery electric quantity percentage interval and charging time, a computer readable storage medium and a wireless earphone. The method includes the steps: writing the corresponding relation between the electric quantity percentage interval and the charging time into the computer readable storage medium ofthe wireless earphone; and for the earphone battery during charging, the initial electric quantity percentage is located in the electric quantity percentage interval, and after each time required forincreasing the rated electric quantity percentage, and if the battery electric quantity variation corresponding to the battery voltage variation does not reach the rated electric quantity percentage,the displayed electric quantity percentage is increased for compensation, so that the earphone can accurately display the battery electric quantity percentage during charging.

Description

technical field [0001] The invention relates to the technical field of wireless earphones, in particular to a method for establishing a corresponding relationship between earphone battery power percentage intervals and charging times, a computer-readable storage medium, and a wireless earphone. Background technique [0002] At present, the wireless earphones on the market are all equipped with lithium batteries for power supply. Due to the small size of the earphones and low power consumption, the battery capacity installed inside the earphones is also relatively low, generally around 750mAh. During the normal use of the headset, actions such as switching on and off, music playing, and charging and discharging will cause changes in the battery power of the headset. Since the corresponding voltage values ​​​​are different when the remaining battery power is different, the traditional method of estimating and displaying the percentage of the battery power of the headset is main...
