In the related art, the wireless headset mainly uses a proximity sensor to determine whether the wireless headset is worn. A detection threshold is typically included in the wireless headset; when wearing detection is carried out, the proximity sensor acquires a current detection value, and then whether the wireless earphone is worn or not is determined through comparison between the current detection value and the detection threshold value; in one example, referring to fig. 1, the proximity sensor of the wireless headset includes two detection thresholds, namely a proximity threshold x and a distance threshold y, and assuming that the current reading value (i.e. the current detection value) of the proximity sensor is z, when z > x, the wireless headset is determined to be worn, and when z < y, the wireless headset is determined to be not worn.

Wherein the detection threshold is generally calibrated and recorded based on a lens of an unworn proximity sensor before the wireless headset leaves a factory; however, as the wireless headset is used, the lens of the proximity sensor may gradually wear, scratch or stain, which may result in a decrease in the accuracy of the wearing detection of the wireless headset based on the proximity sensor if it is still determined whether the wireless headset is worn based on the detection threshold.

Based on this, the embodiment of the present disclosure provides a method for calibrating a proximity sensor of a wireless headset, which considers the problem that a lens of the proximity sensor will gradually wear, scratch or stain along with the use of the wireless headset, and obtains a current detection value through the proximity sensor of the wireless headset when the wireless headset is located in a charging box during the use of the wireless headset, and calibrates a detection threshold of the proximity sensor, so that the calibrated detection threshold of the proximity sensor can be adapted to the lens of the proximity sensor, thereby being beneficial to improving the accuracy of the wearing detection of the wireless headset based on the proximity sensor.

The proximity sensor may be an optoelectronic proximity sensor, for example, an infrared proximity sensor, or the like, or may be another type of sensor. The proximity sensor is mounted on the wireless headset, in one example, the proximity sensor may be disposed on a head of the wireless headset, and the head of the wireless headset is in contact with a cochlea of a human body during normal wearing. Of course, the proximity sensor may be disposed in other positions, which is not limited in this disclosure.

In an exemplary embodiment, the method of calibrating a proximity sensor of a wireless headset may be performed by the wireless headset, for example, by a processor or other component of the wireless headset, and when the wireless headset is located in a charging box, the wireless headset may obtain a current detection value of the proximity sensor and then calibrate a detection threshold of the proximity sensor according to the current detection value; and then in the wearing detection process, the proximity sensor compares the calibrated detection threshold value with the detection value acquired in real time to judge whether the wireless earphone is worn.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for calibrating a proximity sensor of a wireless headset according to an embodiment of the present disclosure, where the method includes:

in step S101, in response to determining that the wireless headset is located in a charging box, a current detection value of the proximity sensor is acquired.

In step S102, calibrating a detection threshold of the proximity sensor according to the current detection value; the detection threshold is used to determine whether the wireless headset is worn.

First, a process of determining that the wireless headset is located in the charging box will be described: the wireless headset may determine that it is in the charging box if it detects that it is in a charging state. Of course, the charging box may detect whether the wireless headset is in a charging state, and feed back a detection result to the wireless headset, so that the wireless headset can determine whether the wireless headset is in the charging box.

Of course, other types of sensors may be used to detect whether the wireless headset is located in the charging box; as an example, for example, a proximity sensor may be installed in the charging box, and the proximity sensor may be used to detect whether the wireless headset is located in the charging box; for example, the charging box is provided with a hall sensor, the wireless headset is provided with a magnet element, the closer the magnet element is to the hall sensor, the larger the hall voltage value detected by the hall sensor, and conversely, the farther the magnet element is from the hall sensor, the smaller the hall voltage value detected by the hall sensor, the charging box can determine whether the wireless headset is located in the charging box through the combination of the hall sensor and the magnet element, but the invention is not limited thereto.

It can be understood that, the calibration timing of the proximity sensor is not limited in any way in the embodiments of the present disclosure, and may be specifically set according to an actual application scenario. In an example, when the computing resources are sufficient, the wireless headset may perform a subsequent calibration step each time the wireless headset is placed in the charging box, in response to determining that the wireless headset is located in the charging box, obtaining the current detection value of the proximity sensor, thereby facilitating to ensure the accuracy of the detection threshold of the proximity sensor and improve the accuracy of the wearing detection of the wireless headset based on the proximity sensor. In another example, in the case of insufficient computing resources, in order to save computing resources, the calibration process of the proximity sensor may be performed only when a preset time period is reached, or the calibration process of the proximity sensor may be performed under the condition that other trigger conditions are met, so that the accuracy of the wearing detection of the wireless headset based on the proximity sensor is improved to some extent.

In some embodiments, the proximity sensor may be mounted on the head of the headset, which is the location of contact with the cochlea of a human being during normal wear.

In some embodiments of the present disclosure, a current detection value used for calibrating the detection threshold of the proximity sensor indicates a distance between the wireless headset and the charging box detected by the proximity sensor after the wireless headset is placed in the charging box, and the obtained current detection value is used for calibration. Referring to fig. 3, if the proximity sensor 11 is installed at the position shown in fig. 3, after the wireless headset 10 is placed in the charging box 20, the detection value obtained by the proximity sensor 11 indicates the distance between the wireless headset 10 and the charging box 20, in this case, the distance between the proximity sensor and the charging box is fixed, so that the current detection value read by the proximity sensor can be used for calibration; however, referring to fig. 4, if the proximity sensor 11 is installed at the position as described in fig. 4, after the wireless headset 10 is placed in the charging box 20, if the charging box 20 is not in the closed state, in which case the distance between the proximity sensor and the charging box is not fixed, the current detection value acquired by the proximity sensor 11 may not accurately indicate the distance between the wireless headset 10 and the charging box 20, so the detection threshold of the proximity sensor 11 cannot be calibrated with the current detection value of the proximity sensor.

Therefore, in order to further ensure the accuracy of the detection threshold of the proximity sensor after calibration, it is necessary to ensure that the current detection value of the proximity sensor obtained with the distance from the proximity sensor to the charging box fixed is obtained at the time of calibration; in some possible implementations, the wireless headset may acquire the current detection value of the proximity sensor when the wireless headset is located in a charging box and the charging box is in an off state. The wireless earphone is located in the charging box, the charging box is determined to be in a closed state, accuracy of the current detection value obtained under the condition that the distance between the proximity sensor and the charging box is fixed is guaranteed, and the wireless earphone can be calibrated by the current detection value. That is to say, the wireless headset can acquire the current detection value of the proximity sensor for performing the subsequent calibration process when the wireless headset is detected to be located in the charging box and the charging box is in the closed state, so that the accuracy of wearing detection based on the proximity sensor is improved.

The process of determining the closed state of the charging box is explained here: referring to fig. 5, the charging box 20 includes a box body 21 and a box cover 22, wherein the box body is configured to be fitted with a capacitor (not shown), the box cover is configured to be fitted with a copper product (not shown), the closer the copper product is to the capacitor, the larger the capacitance value detected by the capacitor is, and the farther the copper product is from the capacitor, the smaller the capacitance value detected by the capacitor is. The charging box may acquire a capacitance value detected by the capacitor, and determine that the charging box is in an off state if the capacitance value is greater than a preset value. The preset value may be specifically set according to an actual application scenario, and this embodiment does not limit this.

Of course, other manners may also be used to determine whether the charging box is in a closed state, for example, the charging box is provided with a hall sensor, the wireless headset is provided with a magnet element, the closer the magnet element is to the hall sensor, the larger the hall voltage value detected by the hall sensor, and the charging box may determine whether the charging box is closed through a combination of the hall sensor and the magnet element.

Referring to fig. 5, when it is determined that the wireless headset 10 is located in the charging box 20 and the charging box 20 is in the closed state, the wireless headset 10 may acquire a current detection value of the proximity sensor 11, and then calibrate a detection threshold of the proximity sensor 11 according to the current detection value; considering that the distance between the wireless headset and the charging box is usually a relatively fixed distance, the obtained current detection value can calibrate the detection threshold value of the proximity sensor, so that the calibrated detection threshold value of the proximity sensor can be adapted to the lens of the proximity sensor, thereby being beneficial to improving the accuracy of wearing detection of the wireless headset based on the proximity sensor.

The method for calibrating the detection threshold of the proximity sensor according to the current detection value may include at least two possible implementations: in a first possible implementation manner, an original detection threshold of the proximity sensor may be adjusted according to the current detection value; in a second possible implementation, the detection threshold of the proximity sensor may be re-determined according to the current detection value. The specific setting can be performed according to the actual application scenario, and this embodiment does not limit this.

In some embodiments, the wireless headset may calibrate the detection threshold of the proximity sensor based on a difference between the current detection value and a reference detection value of the proximity sensor when calibrating the detection threshold of the proximity sensor based on the detection value. The difference between the current detection value and the reference detection value represents the detection difference caused by the abrasion, scratch or contamination of the lens of the proximity sensor, and the detection threshold value of the proximity sensor is calibrated according to the difference between the current detection value and the reference detection value, so that the calibrated detection threshold value can be adapted to the lens of the proximity sensor, and the accuracy of the wearing detection of the wireless earphone based on the proximity sensor is improved.

In some embodiments, the reference detection value may be a value detected by the proximity sensor when the wireless headset is located in a charging box before the wireless headset leaves a factory, and the wireless headset may adjust an initial detection threshold obtained by the proximity sensor before leaving the factory according to a difference between the current detection value and the reference detection value of the proximity sensor. In other embodiments, the reference detection value may also be a value detected by the proximity sensor when the wireless headset was located in the charging box last time, and the wireless headset may adjust the detection threshold obtained by the proximity sensor last time according to a difference between the current detection value and the reference detection value of the proximity sensor. The detection threshold obtained last time is adjusted, so that the influence on user experience caused by overlarge change of the calibrated detection threshold can be avoided.

In a possible implementation manner, the wireless headset may obtain an error value according to a difference between the current detection value and the reference detection value, and then adjust the detection threshold of the proximity sensor according to the error value.

Wherein the error value represents a detection difference caused after a lens of the proximity sensor is worn, scratched, or stained, and may be a difference value between the current detection value and the reference detection value; alternatively, the error value may be a product of the difference value and a preset coefficient, where the preset coefficient is determined according to an attribute of the proximity sensor (the attribute may be a type, a size, or the like of the proximity sensor), and coefficients corresponding to different attributes are different; alternatively, the error value may be determined in other manners, which is not limited in this embodiment.

The detection threshold of the proximity sensor described herein may be an initial detection threshold of the proximity sensor, for example, a detection threshold determined before factory shipment, or a detection threshold determined in a last calibration process of the proximity sensor, which is not limited in this disclosure.

In another possible implementation manner, the detection threshold of the proximity sensor may be determined by at least one threshold parameter, and the wireless headset may calibrate the at least one threshold parameter based on a difference between the current detection value and the reference detection value, and then determine the detection threshold of the proximity sensor by using the calibrated at least one threshold parameter. In this embodiment, the threshold parameter of the proximity sensor is calibrated in the use process of the wireless headset, and then the new detection threshold of the proximity sensor is determined, so that the determined new detection threshold of the proximity sensor can be adapted to the lens of the proximity sensor, thereby being beneficial to improving the accuracy of the wearing detection of the wireless headset based on the proximity sensor.

Further, when the wireless headset calibrates the at least one threshold parameter, an error value may be obtained according to a difference between the current detection value and the reference detection value, and then the at least one threshold parameter is calibrated according to the error value to obtain the calibrated at least one threshold parameter. In this embodiment, the threshold parameter may be changed due to the lens wear, scratch, or contamination of the proximity sensor, so that the detection threshold determined based on the original threshold parameter is no longer applicable, therefore, this embodiment obtains an error value that can reflect the lens wear, scratch, or contamination of the proximity sensor, calibrates the threshold parameter of the proximity sensor using the error value, adapts to the threshold parameter, and adapts to the lens of the proximity sensor, so that the determined new detection threshold of the proximity sensor may also adapt to the lens of the proximity sensor, thereby being beneficial to improving the accuracy of the wearing detection of the wireless headset based on the proximity sensor.

Wherein the error value may be a difference between the current detection value and the reference detection value; alternatively, the error value may be a product of the difference value and a preset coefficient, where the preset coefficient is determined according to an attribute of the proximity sensor (the attribute may be a type, a size, or the like of the proximity sensor), and coefficients corresponding to different attributes are different; alternatively, the error value may be determined in other manners, which is not limited in this embodiment.

Wherein the threshold parameter comprises at least one of: a value detected by the proximity sensor toward a designated object; alternatively, the proximity sensor detects a value in a direction toward a direction without an obstruction. In one example, the threshold parameter includes the first threshold parameter and/or the second threshold parameter, and/or indicates either or both. Referring to fig. 6, the proximity sensor 11 includes a lens, a transmitter for transmitting a light pulse sequence, and a receiver for receiving the light pulse sequence, and the first threshold parameter represents a value detected by the proximity sensor in a direction toward a non-obstruction object. Referring to fig. 7, the proximity sensor 11 includes a lens, a transmitter for transmitting a light pulse sequence, and a receiver for receiving the light pulse sequence, and a designated object is placed in front of the proximity sensor; the second threshold parameter represents a value detected by the proximity sensor toward a designated object; it can be understood that, in the present embodiment, there is no limitation on the number of the second reference detection values, and the number may be specifically set according to an actual application scenario.

In some embodiments, the reference detection value may be a value detected by the proximity sensor when the wireless headset is located in a charging box before the wireless headset leaves a factory, and the wireless headset may calibrate at least one threshold parameter determined by the proximity sensor before leaving the factory according to a difference between the current detection value and the reference detection value of the proximity sensor, and then determine the detection threshold of the proximity sensor using the calibrated at least one threshold parameter. In one example, the at least one threshold parameter that the proximity sensor determines prior to shipment includes at least one of: a value detected by the proximity sensor toward a designated object before shipment of the wireless headset; alternatively, the proximity sensor may detect a value in a case where the proximity sensor is oriented in a direction without a shield before the wireless headset leaves a factory.

In other embodiments, the reference detection value may also be a value detected by the proximity sensor when the wireless headset is located in the charging box last time, and the wireless headset may adjust at least one threshold parameter obtained last time by the proximity sensor according to a difference between the current detection value and the reference detection value of the proximity sensor, and then determine the detection threshold of the proximity sensor using the adjusted at least one threshold parameter. In this embodiment, the threshold parameter obtained last time is adjusted, and then a new detection threshold is determined according to the adjusted threshold parameter, so that it is possible to avoid that the change of the determined new detection threshold is too large to affect user experience.

In an exemplary embodiment, the threshold parameter includes a first threshold parameter and/or a second threshold parameter, and assuming that the wireless headset records a first threshold parameter a1 and a second threshold parameter B1, two detection thresholds of the proximity sensor are determined according to the first threshold parameter and the second threshold parameter, and assuming that the two detection thresholds are a proximity threshold x and a distance threshold y, respectively, x ═ x (B1-a1) × + a1 and y ═ y (B1-a1) × n + a1, where m is a proximity coefficient, n is a distance coefficient, and m > n, and specific values thereof may be specifically set according to an actual application scenario, which is not limited in this embodiment.

Wherein, with the use of the wireless earphone, the lens of the proximity sensor will gradually wear, scratch or stain, etc., so that the light transmittance of the lens is reduced, resulting in the second threshold parameter becoming larger, obviously, if the wearing detection is still performed by using the detection threshold determined based on the second threshold parameter before the wireless earphone is not used, it is obviously inaccurate.

Thus, the wireless headset may calibrate the first and second threshold parameters a1 and B1 based on a difference between the detection value and a reference detection value of the proximity sensor.

In a possible implementation manner, the reference detection value of the proximity sensor is a value detected by the proximity sensor when the wireless headset is located in a charging box before the wireless headset leaves a factory, the wireless headset may obtain an error value according to a difference between the detection value and the reference detection value of the proximity sensor, then calibrate the first threshold parameter a1 and the second threshold parameter B1 recorded before leaving the factory based on the error value, respectively, obtain the calibrated first threshold parameter a1 and the calibrated second threshold parameter B1, and further may re-determine the detection threshold of the proximity sensor, that is, the proximity threshold x and the distance threshold y, using the calibrated first threshold parameter a1 and the calibrated second threshold parameter B1. In this embodiment, the threshold parameter for determining the detection threshold is calibrated in the use process of the wireless headset, so that the accuracy of the obtained detection threshold of the proximity sensor is ensured, and the obtained detection threshold of the proximity sensor can be adapted to the lens of the proximity sensor, thereby improving the accuracy of the wearing detection of the wireless headset based on the proximity sensor.

In another possible implementation manner, the reference detection value may also be a value detected by the proximity sensor when the wireless headset is located in the charging box last time, the wireless headset may obtain an error value according to a difference between the detection value and the reference detection value of the proximity sensor, then calibrate the first threshold parameter a1 and the second threshold parameter B1 obtained last time based on the error value, respectively, obtain the calibrated first threshold parameter a1 and the calibrated second threshold parameter B1, and further may re-determine the detection threshold of the proximity sensor, that is, the proximity threshold value x and the distance threshold value y, using the calibrated first threshold parameter a1 and the calibrated second threshold parameter B1. In the embodiment, the threshold parameter for determining the detection threshold is calibrated in the use process of the wireless earphone, so that the accuracy of the obtained detection threshold of the proximity sensor is ensured, the obtained detection threshold of the proximity sensor can be adapted to the lens of the proximity sensor, and the accuracy of wearing detection of the wireless earphone based on the proximity sensor is improved; in addition, the threshold parameter obtained last time is calibrated, and then a new detection threshold is determined according to the calibrated threshold parameter, so that the influence on user experience caused by overlarge change of the determined new detection threshold can be avoided.

In one example, the error value may be a difference between the detection value and a threshold parameter of the proximity sensor, and then a calibrated first threshold parameter a1 may be obtained from a sum of the error value and the first threshold parameter a1, and a calibrated second threshold parameter B1 may be obtained from a sum of the error value and the second threshold parameter B1; of course, the error value and the calibrated threshold parameter may also be obtained in other manners, and may be specifically set according to an actual application scenario, for example, the error value is a product of the difference value and a preset coefficient, and the calibrated threshold parameter is a product of the threshold parameter and the error value, but is not limited thereto.

In an exemplary embodiment, a first threshold parameter a1, a second threshold parameter B1, and a reference detection value C1 of the proximity sensor are calibrated and recorded before the wireless headset leaves factory, during the use of the wireless headset, when the wireless headset is located in a charging box and the charging box is in a closed state, a current detection value C2 of the proximity sensor is obtained, an error value D is obtained according to a difference between the current detection value and the reference detection value of the proximity sensor, for example, D is C2-C1, the first threshold parameter a1 and the second threshold parameter B1 are calibrated respectively based on the error value, a calibrated first threshold parameter a1 and a calibrated second threshold parameter B1 are obtained, for example, the calibrated first threshold parameter a2 is set, a2 is a1+ D, the calibrated second threshold parameter B2 is set, b2 ═ B1+ D; and then re-determining the detection threshold of the proximity sensor by using the calibrated threshold parameter, wherein the detection threshold comprises a proximity threshold and a distance threshold, and if the calibrated proximity threshold is x2 and the calibrated distance threshold is y2, x2 is (B2-a2) × m + a2 and y2 is (B2-a2) × n + a 2. In the embodiment, the first threshold parameter and the second threshold parameter cannot be directly obtained in the use process of the wireless headset, and therefore, the first threshold parameter and the second threshold parameter are calibrated by using the difference between the current detection value obtained by the proximity sensor and the reference detection value of the proximity sensor when the wireless headset is located in the charging box and the charging box is in the closed state, so as to re-determine the detection threshold, so that the obtained detection threshold of the proximity sensor can be adapted to the lens of the proximity sensor, and the accuracy of wearing detection of the wireless headset based on the proximity sensor is improved.
