The step is similar to step 101, and is not described herein again.

The present embodiment does not limit the temperature sensor to the temperature related to the user, such as the temperature in the ear canal of the user or the body temperature of the user, as long as it can be ensured that the temperature sensor can collect the temperature related to the user when the user wears the wireless headset.
Specifically, the specific type of the temperature sensor arranged in the wireless earphone can be set by a designer according to a practical scene and user requirements, and a contact temperature sensor can be selected, for example, when the user wears the wireless earphone, the temperature sensor arranged at an ear-entering position in contact with the ear of the user can acquire the body temperature of the user; non-contact temperature sensors may also be used, such as a temperature sensor positioned at an in-ear location into the ear canal of the user to capture the temperature within the ear canal of the user when the wireless headset is worn by the user. The present embodiment does not set any limit to this.
It is understood that the temperature value in this step may be a value corresponding to the temperature in the ear canal of the user or the body temperature of the user collected by the temperature sensor disposed at the ear insertion position of the wireless earphone. As for the specific content of the temperature value, the designer may set the temperature value according to the type of the temperature sensor, as long as the temperature related to the user can be reflected, and the embodiment does not limit the temperature value.
It should be noted that, as for the execution sequence of this step and step 201, the designer may set itself according to the practical scenario, and may first obtain the first light value and the second light value by using the first light sensor and the second light sensor, and then obtain the temperature value by using the temperature sensor; or a temperature sensor is used for acquiring a temperature value, and then a first optical value and a second optical value are acquired by using a first optical sensor and a second optical sensor; the first light value, the second light value and the temperature value can be obtained by simultaneously utilizing the first light sensor, the second light sensor and the temperature sensor.
Step 203: and determining the wearing condition of the wireless earphone according to the difference value between the temperature value and the preset temperature value and the difference value between the first light value and the second light value.
The specific calculation mode according to the difference between the temperature value and the preset temperature value in the step can be set by a designer, and can be an absolute value of the difference between the temperature value and the preset temperature value; the difference between the preset temperature value and the temperature value can also be used, for example, the preset temperature value can be a preset human body temperature value; the difference between the temperature value and the preset temperature value can also be used, for example, the preset temperature value can be a preset room temperature value. The present embodiment does not set any limit to this.
Correspondingly, the specific value of the preset temperature value can be set by a designer or a user according to a practical scene and user requirements, and can be directly set as a fixed human body temperature value or a fixed room temperature value, such as 37 ℃ or 24 ℃; the temperature value (human body temperature value) collected by the temperature sensor can be set when the wireless earphone is in a wearing state, or the temperature value (room temperature value) collected by the temperature sensor can be set when the wireless earphone is in a non-wearing state, namely the preset temperature value can be adjusted according to the self condition or the environment condition of the user. The present embodiment does not set any limit to this.
It can be understood that, an object of this embodiment may be to determine, on the basis of the previous embodiment, a wearing condition of the wireless headset according to a variation between illumination intensities of the ambient light collected by the first light sensor and the second light sensor and a difference between a temperature value collected by the temperature sensor and a preset temperature value, so as to improve accuracy of detecting the wearing condition of the wireless headset.
Specifically, for the specific manner of determining the wearing condition of the wireless headset in this step according to the difference between the temperature value and the preset temperature value and the difference between the first light value and the second light value, the wearing condition of the wireless headset may be determined by directly comparing the difference between the temperature value and the preset temperature value and the difference between the first light value and the second light value with the respective corresponding threshold values, as shown in fig. 3, this step may include:
s301: calculating to obtain a first difference value and a second difference value; the first difference is the difference between the second light value and the first light value, and the second difference is the difference between the preset temperature value and the temperature value.
It is understood that the preset temperature value in this step may be a preset human body temperature value, such as 37 ℃.
S302: judging whether the first difference is larger than or equal to a first threshold value and the second difference is smaller than or equal to a second threshold value; if yes, determining that the wireless earphone is in a wearing state; if not, determining that the wireless earphone is not worn.
The purpose of this step may be to determine that the wireless headset is in a worn state or not when a variation between the illumination intensity of the ambient light collected by the second light sensor at the non-in-ear position and the illumination intensity of the ambient light collected by the first light sensor at the in-ear position is greater than or equal to a first threshold, and a difference between a preset human body temperature value and a temperature value collected by the temperature sensor is less than or equal to a second threshold. Specifically, the specific value setting of the first threshold and the second threshold may be set by a designer, which is not limited in this embodiment.
Specifically, for the specific determination process in this step, it may be determined whether the first difference is greater than or equal to the first threshold, and if so, it may be determined whether the second difference is less than or equal to the second threshold, that is, in this embodiment, the first light value and the second light value may be obtained first to calculate the first difference, and if the first difference is greater than or equal to the first threshold, then the temperature value is obtained, and if the first difference is less than the first threshold, it is determined that the wireless headset is in an unworn state, and it is not necessary to start the temperature sensor to obtain the temperature value; whether the second difference is smaller than or equal to the second threshold value or not can be judged, if yes, whether the first difference is larger than or equal to the first threshold value or not is judged, namely, in the embodiment, the temperature value can be obtained firstly to calculate the second difference, if the second difference is smaller than or equal to the second threshold value, the first light value and the second light value are obtained, if the second difference is larger than the second threshold value, the wireless headset is determined to be in an unworn state, and the first light value and the second light value do not need to be obtained by starting the first light sensor and the second light sensor; it may also be determined whether the first difference is greater than or equal to a first threshold and the second difference is less than or equal to a second threshold at the same time. As long as it can be determined whether the first difference is greater than or equal to the first threshold and the second difference is less than or equal to the second threshold, the embodiment does not limit this.
It can be understood that, the purpose of this step may be to determine the wearing condition of the wireless headset by directly using the difference between the temperature value and the preset temperature value and the difference between the first light value and the second light value to compare with the corresponding first threshold and second threshold, so as to quickly and accurately detect the wearing condition of the wireless headset. In order to further improve the accuracy of detecting the wearing condition of the wireless headset in the method provided by this embodiment, the present step may further determine the current wearing condition of the wireless headset according to the previous wearing condition of the wireless headset, and the present step may be to determine whether the first difference is greater than or equal to the first threshold and the second difference is less than or equal to the second threshold when the wireless headset is in an unworn state; if yes, determining that the wireless earphone is in a wearing state; if not, determining that the wireless earphone is not worn. When the wireless earphone is in a wearing state, judging whether the first difference value is smaller than a first threshold value and the second difference value is larger than a second threshold value; if yes, determining that the wireless earphone is not worn; if not, determining that the wireless earphone is in a wearing state. The present embodiment does not set any limit to this.

The method can comprise the following steps:
step 401: and acquiring a first light value acquired by the first light sensor, a second light value acquired by the second light sensor and a temperature value acquired by the temperature sensor.
Here, this step is similar to step 201 and step 202, and is not described herein again.
Step 402: calculating to obtain a first difference value and a second difference value; the first difference is the difference between the second light value and the first light value, and the second difference is the difference between the preset temperature value and the temperature value.
It is understood that the preset temperature value in this step may be a preset human body temperature value, such as 37 ℃.

Wherein for the firstThe specific calculation method of the first weight score corresponding to the ratio and the second weight score corresponding to the difference between 1 and the second ratio can be set by a designer according to a practical scenario and a user requirement, for example, the weight scores of 100 can be occupied by the ambient light detection condition and the temperature detection condition (that is, the weight value is between 0 and 100), taking the ambient light detection condition as an example, when the wireless headset is in an unworn state, the first light value (a) collected by the first light sensor and the second light value (B) collected by the second light sensor are both 20, when the wireless headset is in an unworn state, the first light value (a) collected by the first light sensor is changed into 0, and the second light value (B) collected by the second light sensor is not changed, then the first difference value is 20, and at this time, a is changed from 20->The change of 0 corresponds to 0->100, the calculation formula can be
Wherein the content of the first and second substances,
the first ratio is X, which is a first weight division corresponding to the first ratio, i.e. when a becomes 10, the first weight division is 50, when a becomes 0, the maximum variation is reached, and the first weight division is 100. The second weight score corresponding to the difference of 1 minus the second ratio in the temperature detection condition can be set correspondingly in a manner similar to the above calculation, for example, the calculation formula can be
Wherein the content of the first and second substances,
and the second ratio, C is the temperature value collected by the temperature sensor, D is a preset temperature value of 37 ℃, and Y is a second weight corresponding to the difference of 1 minus the second ratio. As long as the first weight score corresponding to the first ratio and the second weight score corresponding to the difference between 1 and the second ratio can be calculated, the embodiment does not limit this.
Step 404: judging whether the first difference value is larger than or equal to a third threshold value and the second difference value is smaller than or equal to a fourth threshold value; if yes, go to step 405; if not, go to step 406.

If the first difference is smaller than the third threshold and the second difference is smaller than the fourth threshold, it may be considered that if the user wears the wireless headset at this time, the wireless headset is in a dark state and the difference between the outside temperature and the body temperature of the user is large, and in step 406, the smaller second weight threshold may be selected to determine whether the wireless headset is in a worn state; otherwise, a normal larger first weight threshold may be selected to determine whether the wireless headset is in a worn state, via step 405.

Based on any of the above embodiments, in order to further improve the accuracy of detecting the wearing condition of the wireless headset, considering the influence of extreme conditions, such as darkness and low temperature of the external environment, on the detection of the wearing condition of the wireless headset, when the wireless headset is in a wearing state, please refer to fig. 5, where fig. 5 is a flowchart of another method for detecting the wearing condition of the wireless headset according to an embodiment of the present invention. The method can comprise the following steps:
step 501: and acquiring a first light value acquired by the first light sensor, a second light value acquired by the second light sensor and a temperature value acquired by the temperature sensor.
Here, this step is similar to step 201 and step 202, and is not described herein again.
