All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a first flowchart of a method for detecting an earphone entering/exiting from a box according to an embodiment of the present application.
The method for detecting the earphone in and out box provided by the embodiment of the application can comprise the following steps:
step S101: and acquiring real-time pressure data acquired by a pressure sensor arranged in the wireless earphone charging box.
Step S102: determining the earphone in-out box state based on the real-time pressure data.

The method for detecting the earphone in and out of the box comprises the steps that real-time pressure data collected by a pressure sensor arranged in a wireless earphone charging box is obtained; determining the earphone in-out box state based on the real-time pressure data. According to the method for detecting the earphone in-out box, the pressure sensor is installed in the wireless earphone charging box, the state of the earphone in-out box is determined by means of real-time pressure data collected by the pressure sensor, and the pressure sensor cannot interfere with the functions of components of the wireless earphone charging box and has small influence on the power consumption of the wireless earphone charging box, so that the detection of the state of the wireless earphone in-out box can be realized under the conditions of no interference and low power consumption.
In the earphone in-out box detection method provided by the embodiment of the application, when the objects entering the wireless earphone charging box are different, the objects are affected by the weight of the objects, the pressure data collected by the pressure sensor are different, so that the types of the objects entering the wireless earphone charging box can be judged by means of the pressure data collected by the pressure sensor, and therefore the process of determining the state of the earphone in-out box based on the real-time pressure data can be specifically as follows: calculating the absolute value of the difference between the real-time pressure data and the pressure base value; judging whether the absolute value is larger than a preset threshold value, if so, judging that the earphone is in the box, and if not, judging that the earphone is out of the box; determining the state of the earphone entering and exiting the box based on the judgment result that the earphone is in the box or outside the box; the pressure base value is a pressure value acquired by the pressure sensor when the wireless earphone charging box is empty.
In practical application, after the earphone enters the wireless earphone charging box, the pressure sensor acquires pressure data, when the earphone does not enter the wireless earphone charging box, the pressure data of the pressure sensor is approximately zero, and in the application process of the wireless earphone charging box, a user generally only places the earphone in the wireless earphone charging box, and the earphone quality generally does not change, so that the pressure data acquired by the pressure sensor is close to a certain value, therefore, the absolute value of the difference value between the real-time pressure data and the pressure base value can be calculated, the type of an object entering the wireless earphone charging box is represented by the absolute value, and then whether the absolute value is greater than a preset threshold value is judged, namely whether the object entering the wireless earphone charging box is the earphone is judged, if so, the earphone is judged to be in the wireless earphone charging box, and if not, the earphone is judged to be outside the wireless earphone charging box.
Referring to fig. 2, fig. 2 is a second flowchart of a method for detecting an earphone in/out box according to an embodiment of the present application.
The method for detecting the earphone in and out box provided by the embodiment of the application can comprise the following steps:
step S201: and acquiring real-time pressure data acquired by a pressure sensor arranged in the wireless earphone charging box.
Step S202: the absolute value of the difference between the real-time pressure data and the pressure base value is calculated.
Step S203: judging whether the absolute value is larger than a preset threshold value or not; if the absolute value is greater than the preset threshold, executing step S204; if the absolute value is smaller than the predetermined threshold, step S206 is executed.
Step S204: judging whether the real-time pressure data is within a preset pressure value range; if the real-time pressure data is within the preset pressure value range, step S205 is executed, and if the real-time pressure data is not within the preset pressure value range, step S206 is executed.
Step S205: the earphone is judged to be in the box.

Step S207: and determining the state of the earphone entering and exiting the box based on the judgment result that the earphone is in the box or outside the box.
In practical application, under the condition that the absolute value is greater than the preset threshold value, the earphone may not enter the wireless earphone charging box, in order to enhance the accuracy of the earphone in-out box detection method provided by the application, the pressure value range collected by the pressure sensor can be collected firstly after the earphone enters the box, that is, the preset pressure value range representing the earphone entering the box is collected firstly, so that after the absolute value is greater than the preset threshold value, whether the real-time pressure data is in the preset pressure value range can be further judged, if the real-time pressure data is in the preset pressure value range, the earphone is judged to be in the box, and if the real-time pressure data is not in the preset pressure value range, the earphone is judged to be out of the box.
In the method for detecting the earphone entering and exiting box provided by the embodiment of the application, before judging whether the absolute value is greater than the preset threshold value, the historical pressure data representing the earphone entering box can be obtained in a preset amount; a preset pressure value range is determined based on the historical pressure data.
In practical application, due to the abrasion of the earphones or the change of the state of the wireless earphone charging box, pressure data collected by the pressure sensor can be changed, so that the pressure data representing the earphones in the box can be different at different moments, but the earphones can be represented in the box, therefore, in order to guarantee that the preset pressure value range can accurately represent the earphones in the box as far as possible, the historical pressure data representing the earphones in the box in preset quantity can be obtained, the preset pressure value range is determined based on the historical pressure data, in the process, the value of the preset quantity can be determined according to actual needs, and the historical pressure data can be a group of pressure data which are closest to the current moment.
In a specific application scenario, in the process of determining the preset pressure value range based on the historical pressure data, in order to avoid the influence of fluctuating pressure data on the preset pressure value range, the maximum value of the first quantity and the minimum value of the second quantity can be deleted from the historical pressure data, and the remaining historical pressure data is used as target historical pressure data; and then determining a preset pressure value range based on the target historical pressure data. The values of the first number and the second number may be determined according to actual needs, and the values of the first number and the second number may be equal or unequal. Specifically, in the process of determining the preset pressure value range based on the target historical pressure data, the minimum value and the maximum value in the target historical pressure data may be used as two critical values of the preset pressure value range, and the pressure values between the two critical values are all attributed to the preset pressure value range.
In the method for detecting the earphone in-out box provided by the embodiment of the application, because the real-time pressure data can only represent whether the earphone is in the box at the current moment or not, and the earphone in-out box represents the state change of the earphone, the final state of the earphone in-out box needs to be determined according to whether the earphone is in the box before the current moment or not, so that the historical real-time pressure data acquired by the pressure sensor at the last moment at the current moment can be acquired in the process of determining the state of the earphone in-out box based on the real-time pressure data; and determining the state of the earphone in and out of the box based on the historical real-time pressure data and the real-time pressure data.
Specifically, whether the earphone is in the box at the last moment can be determined based on the historical real-time pressure data, the judging method can be the same as the method for judging whether the earphone is in the box based on the real-time pressure data, and then if the historical real-time pressure data represents that the earphone is in the box and the real-time pressure data represents that the earphone is out of the box, the earphone is judged to be in the out-of-box state; if the historical real-time pressure data represents that the earphone is outside the box and the real-time pressure data represents that the earphone is inside the box, the earphone is judged to be in a box-in state; in addition, when both the historical real-time pressure data and the real-time pressure data represent that the earphone is in the box or represent that the earphone is out of the box, the condition that the earphone is in and out of the box can only be indicated.
