it should be noted that, the wearing detection method provided by the present invention is suitable for in-ear devices integrated with a capacitance sensor, such as various in-ear headphones, the capacitance sensor provided by the present embodiment uses various types of capacitors as sensing elements, and converts the measured physical quantity or mechanical quantity into a capacitance variation, in short, the in-ear device integrated with a capacitance sensor contacts with an auricle to generate a physical quantity (force), the capacitance sensor can convert the physical quantity into a capacitance, the greater the contact force is, the greater the physical quantity is, the greater the capacitance converted from the physical quantity is, and because the sensitivity (adjustable sensitivity) of the capacitance sensor is greater, the in-ear device integrated with a capacitance sensor has a certain detected capacitance value, which is referred to as an initial capacitance value, and the in-ear device integrated with a capacitance sensor needs to undergo multiple experiments before being used by a user, so as to measure the capacitance value of the in-ear device integrated with a capacitance sensor when the in-ear device is used for simulating the capacitance value, the in-ear device is implemented to simulate the capacitance value.
Step S20, determining a capacitance threshold according to the initial capacitance value and the experimental capacitance value;
it should be noted that, if the experimental capacitance value is a capacitance value generated when the in-ear device is used, according to the characteristics of the capacitance sensor (the larger the force of contact is, the larger the generated physical quantity is, the larger the capacitance converted from the physical quantity is), the experimental capacitance values can be determined to be larger than the initial capacitance value, while the capacitance threshold proposed by the invention includes an upper limit capacitance value and a lower limit capacitance value, wherein the lower limit capacitance value refers to the smallest capacitance value which can be determined to be in the in-ear device in use state, and the upper limit capacitance value can be the average value or the smallest value of the capacitance value with the upper limit capacitance value being 20% before the upper limit capacitance value, specifically, if the number of experiments performed by the in-ear device is 10000 times, the experimental capacitance values are correspondingly obtained, then the experimental capacitance values are sequenced from large to small, the average value of the experimental capacitance values which are arranged in front 2000 is calculated, the calculated average value of the experimental capacitance values can be used as the upper capacitance value, and the lower limit capacitance value is the average value, and the average value calculated average value is calculated as the upper capacitance value, and the average value is calculated as the average value of the upper capacitance value, and the average value is 3, and the average value is calculated as the average value is 3, and the average value is not equal to the upper limit capacitance value and the average value is 3, and the average value is larger than the average value and the average value is 3.

It should be noted that, the in-ear device according to the present invention may determine the running state of the in-ear device according to the wearing state thereof, for example, if the in-ear device is a bluetooth headset, the bluetooth headset is in a state of playing music when in the wearing state, the state of playing music will be paused after the bluetooth headset is changed from the wearing state to the non-wearing state.
The method comprises the steps of marking experimental capacitance values in advance, obtaining the experimental capacitance values marked in advance as wearing states in the experimental capacitance values when the wearing detection program provided by the invention runs, determining an upper limit capacitance value according to the experimental capacitance values marked in advance as wearing states in the experimental capacitance values, specifically, obtaining the average value or the minimum value of the experimental capacitance values marked in advance as wearing states, taking the obtained average value as the upper limit capacitance value, determining a lower limit capacitance value according to the experimental capacitance values marked in advance as unworn states in the experimental capacitance values, specifically, obtaining the average value or the minimum value of the experimental capacitance values marked in advance as unworn states, and taking the obtained average value as the lower limit capacitance value.

and a2, if the target capacitance value is greater than or equal to the initial capacitance value, executing the step of determining the wearing state of the in-ear device at the current moment according to the magnitude relation between the target capacitance value and the capacitance threshold value.
It should be noted that, the initial capacitance value refers to a detected capacitance value existing when the in-ear device is not in the ear before the factory stage, the initial capacitance value is small, if the target capacitance value is smaller than the initial capacitance value, it indicates that the in-ear device has been used by the user for a long time, and the sensitivity of the capacitance sensor integrated in the in-ear device has changed, in this case, the upper limit capacitance value and the lower limit capacitance value of the in-ear device need to be adjusted, and the adjustment method may be to adjust the upper limit capacitance value and the lower limit capacitance value of the in-ear device by a certain value synchronously, and the purpose of adjusting the upper limit capacitance value and the lower limit capacitance value of the in-ear device is to adjust the sensitivity of the in-ear device for detecting the wearing state, so that the wearing state of the in-ear device can also be accurately detected; and if the target capacitance value is greater than or equal to the initial capacitance value, executing the step of determining the wearing state of the in-ear device at the current moment according to the magnitude relation between the target capacitance value and the capacitance threshold value.
Further, in a possible embodiment, the step of refining in step S30 further includes:
step a3, if the target capacitance value is larger than the upper limit capacitance value, determining that the in-ear device is in a wearing state at the current moment;
and a step a4 of determining that the in-ear device is in an unworn state at the current moment if the target capacitance value is smaller than the lower limit capacitance value.
It should be noted that, if the current time is the time when the user just starts to use the in-ear device, the upper limit capacitance value provided in this embodiment is the upper limit capacitance value determined by the in-ear device when leaving the factory, and in this case, if the target capacitance value detected at the current time is greater than the upper limit capacitance value determined by the in-ear device when leaving the factory, it is determined that the in-ear device is in the wearing state at the current time; if the detected target capacitance value at the current moment is smaller than the lower limit capacitance value determined by the in-ear device when leaving the factory, determining that the in-ear device is in a non-wearing state at the current moment.
Further, in a possible embodiment, the steps after the step S30 include:
step S40, when the in-ear device is changed from the wearing state to the unworn state, adjusting the audio output function of the in-ear device from the on state to the off state.
It should be noted that, the in-ear device provided by the invention can determine the running state of the in-ear device according to the wearing state of the in-ear device, for example, if the in-ear device is detected to be in the wearing state by the capacitive sensor integrated in the in-ear device, the in-ear device can start the audio output function, that is, the in-ear device can be connected with other devices, so that the devices connected with the in-ear device can output audio through the in-ear device; if the integrated capacitive sensor in the in-ear device detects that the in-ear device is in a non-wearing state, the in-ear device can close the audio output function, in this case, the equipment connected with the in-ear device cannot output audio through the in-ear device, specifically, if the in-ear device changes from the non-wearing state to the wearing state, the connection function of the in-ear device can be directly opened, connection with other equipment capable of outputting audio is established, conversely, if the in-ear device changes from the wearing state to the non-wearing state, and before the state change, connection is established between the in-ear device and other equipment capable of outputting audio, and after the state change, connection between the in-ear device and other equipment capable of outputting audio is disconnected.
The invention provides a wearing detection method, a device, equipment and a computer readable storage medium, wherein the wearing detection method is applied to an in-ear device integrated with a capacitance sensor, an initial capacitance value and an experimental capacitance value are firstly obtained through the capacitance sensor, and then a capacitance threshold value is determined according to the initial capacitance value and the experimental capacitance value; finally, a target capacitance value at the current moment is obtained, and the wearing state of the in-ear device at the current moment is determined according to the size relation between the target capacitance value and the capacitance threshold.
Further, referring to fig. 4, a second embodiment of the wearing detection method of the present invention is proposed on the basis of the above-described embodiment of the present invention.
This embodiment is a step of refining step S30 in the first embodiment, and is different from the above-described embodiment of the present invention in that:
step S31, if the target capacitance value belongs to a buffer interval, acquiring a capacitance trend before the current moment and a historical capacitance value between the target moment and the current moment, wherein the minimum value of the buffer interval is the lower limit capacitance value, the maximum value of the buffer interval is the upper limit capacitance value, and the target moment is before the current moment;
Step S32, defining that the buffer interval comprises a high buffer interval and a low buffer interval, if the capacitance trend is a descending trend and the historical capacitance value is in the high buffer interval, determining that the in-ear device is in a wearing state at the current moment, and adjusting the upper limit capacitance value;
step S33, if the capacitance trend is a decreasing trend and the historical capacitance value is in the low buffer zone, determining that the in-ear device is in an unworn state at the current time, and adjusting the lower limit capacitance value.
It should be noted that, the interval between the upper limit capacitance value and the lower limit capacitance value is the buffer interval in this embodiment, if the target capacitance value belongs to the buffer interval, the capacitance trend before the current time is obtained, the capacitance trend proposed in this embodiment includes an ascending trend, a descending trend and a smooth trend, it can be understood that, as shown in fig. 3, the capacitance value detected by the capacitance sensor is in the descending trend before the current time, and if the target capacitance value belongs to the buffer interval, the capacitance trend before the current time is obtained, and the historical capacitance value between the target time and the current time is obtained, according to fig. 3, the target time is before the current time, then the buffer interval is defined to include a high buffer interval and a low buffer interval, if the capacitance trend is the descending trend, and the historical capacitance value is in the high buffer interval, then the in the wearing state at the current time is determined, and the upper limit capacitance value is adjusted, which indicates that the capacitance value detected by the capacitance sensor is in the process before the target time, but the capacitance value is in the loose state is detected by the capacitance sensor, and the situation that the capacitance value is in the vicinity of the current time is still in the wearing state is not required to be reduced, and the situation that the capacitance sensor is in the wearing state is required to be in the state is still reduced.
If the capacitance trend is a falling trend and the historical capacitance value is in a low buffer zone, determining that the in-ear device is in an unworn state at the current moment and adjusting the lower limit capacitance value, wherein the situation indicates that the capacitance value detected by the capacitance sensor is reduced and falls to the vicinity of the lower limit capacitance value in the process from the time before the target moment of the in-ear device, which indicates that the in-ear device is taken out of the human ear, so that the capacitance value detected by the capacitance sensor is reduced, and the reason that the capacitance value detected by the capacitance sensor is not reduced below the lower limit capacitance value can be that oil stains or sweat stains exist on the surface of the earphone, so that the capacitance value detected by the capacitance sensor is increased.
Further, in a possible embodiment, the steps after the step S31 further include:
step S34, if the capacitance trend is rising trend and the historical capacitance value is in the high buffer zone, determining that the in-ear device is in a wearing state at the current moment, and adjusting the upper limit capacitance value;
Step S35, if the capacitance trend is an ascending trend and the historical capacitance value is in the low buffer zone, determining that the in-ear device is in an unworn state at the current time, and adjusting the lower limit capacitance value.
If the capacitance trend is rising trend and the historical capacitance value is in a high buffer zone, the in-ear device is determined to be in a wearing state at the current moment, and the upper limit capacitance value is adjusted, wherein the situation indicates that the capacitance value detected by the capacitance sensor rises and reaches the vicinity of the upper limit capacitance value in the process from the time before the target moment to the current moment, and the in-ear device is put into the human ear, so that the capacitance value detected by the capacitance sensor rises, but the in-ear device is not well attached to the auricle due to the difference of the internal structures of the human ear, so that the capacitance value detected by the capacitance sensor does not rise to be above the upper limit capacitance value, in this case, the in-ear device is determined to be in the wearing state, and the upper limit capacitance value is adjusted, so that the in-ear device put into the human ear is more convenient to be determined to be in the wearing state after the current moment.
If the capacitance trend is rising trend and the historical capacitance value is in a low buffer zone, determining that the in-ear device is in an unworn state at the current moment, and adjusting the lower limit capacitance value, wherein the situation indicates that the capacitance value detected by the capacitance sensor rises and only reaches the vicinity of the lower limit capacitance value in the process from the time before the target moment to the current moment, which indicates that the in-ear device can be mistakenly touched, so that the capacitance value detected by the capacitance sensor rises, but the capacitance value detected by the capacitance sensor does not rise to the vicinity of the upper limit capacitance value, and in this case, determining that the in-ear device is in the unworn state, but adjusting the lower limit capacitance value is needed, so that the mistakenly touched in-ear device is more convenient to determine as the unworn state after the current moment.
According to the wearing detection method, the buffer interval comprises the high buffer interval and the low buffer interval, the trend of the capacitance value and the interval where the capacitance value is located are combined, and the wearing detection method corresponds to different scenes in reality, so that the wearing detection method has higher detection accuracy.
In addition, referring to fig. 5, an embodiment of the present invention further proposes a wear detection device, including:
the capacitance value acquisition module 10 is used for acquiring a pre-stored experimental capacitance value and acquiring an initial capacitance value through the capacitance sensor;
