Based on the hardware structure of the equipment, the embodiment of the wearing detection method is provided.
Present earphone is worn to detect and is adopted infrared detection and capacitive touch sensing to detect often, because infrared detection has very high error recognition rate, so adopt capacitive touch sensing to detect the earphone and wear the state and become the selection in order more and more earphones to wear detection scheme, however, prior art often only uses capacitive sensor to detect the wearing state of earphone, because everyone's auricle difference in structure, owing to wear not hard up or earphone surface has the sweat, lead to the earphone to wear the existence that the condition such as appearance error detection appears, therefore, prior art has bluetooth earphone to wear to detect the recognition rate low, detect insensitive scheduling problem, can't solve the influence of auricle difference to wearing the detection simultaneously.
In view of the above problem, the present invention provides a wear detection method, and with reference to fig. 2, in a first embodiment of the wear detection method of the present invention, the wear detection method includes:
step S10, obtaining a prestored experimental capacitance value, and obtaining an initial capacitance value through the capacitance sensor;
it should be noted that the wearing detection method proposed by the present invention is suitable for in-ear devices integrated with a capacitive sensor, such as various in-ear earphones, the capacitive sensor proposed by this embodiment uses various capacitors as sensing elements, and converts a physical quantity or a mechanical quantity to be measured into a conversion device of a capacitance variation, in short, the in-ear device integrated with the capacitive sensor contacts with the auricle when entering the ear to generate a physical quantity (force), the capacitive sensor can convert the physical quantity into a capacitance, the greater the force of the contact, the greater the generated physical quantity, the greater the capacitance converted from the physical quantity, the greater the sensitivity of the capacitive sensor (which can be adjusted), the in-ear device integrated with the capacitive sensor has a certain detected capacitance value when the in-ear device is not in-ear, which is referred to as an initial capacitance value in this embodiment, the in-ear device integrated with the capacitive sensor needs to be subjected to a plurality of experiments before being used by a user to measure the capacitance value detected by the in-ear device integrated with the capacitive sensor in the simulation use, and the capacitance value measured in the simulation experiment is collectively referred to as an experiment capacitance value in the embodiment.
Step S20, determining a capacitance threshold value according to the initial capacitance value and the experimental capacitance value;
it should be noted that, if the experimental capacitance is a capacitance generated by the simulated in-ear device during use, it may be determined that the experimental capacitances are both larger than the initial capacitance according to characteristics of the capacitive sensor (the larger the contact force is, the larger the generated physical quantity is, and the larger the capacitance converted from the physical quantity is), and the capacitance threshold proposed by the present invention includes an upper limit capacitance and a lower limit capacitance, where the lower limit capacitance refers to a minimum capacitance that can determine that the in-ear device is in a use state, and the upper limit capacitance may be an average value or a minimum value of capacitances ranked 20% of the experimental capacitances in numerical magnitude, specifically, if the number of times of the experiment that the in-ear device is simulated for use is 10000 times, 10000 experimental capacitances are obtained correspondingly, and then the experimental capacitances are sorted from large to small, an experimental capacitance listed in the top 2000 is selected from the sorted, and an average value of the experimental capacitances listed in the top 2000 is obtained, the obtained average value may be used as the upper limit capacitance value, and similarly, the calculation method of the lower limit capacitance value is similar to the upper limit capacitance value, and the lower limit capacitance value may be the average value or the minimum value of the capacitance values 20% after the numerical rank in the experimental capacitance value, so as to determine the lower limit capacitance value, as shown in fig. 3, the lower limit capacitance value is greater than the initial capacitance value, and the upper limit capacitance value is greater than the lower limit capacitance value, where fig. 3 is only for explaining the magnitude relationship among various capacitance values, and the positions of various capacitance values in fig. 3 do not represent a specific numerical proportion.
Further, in a possible embodiment, the step S20 of determining the capacitance threshold according to the initial capacitance value and the experimental capacitance value may include:
and step S21, acquiring the experimental capacitance value marked as the wearing state in the experimental capacitance values, and determining an upper limit capacitance value according to the experimental capacitance value marked as the wearing state.
Step S22, obtaining an experimental capacitance value marked as an unworn state in the experimental capacitance values, and determining a lower-limit capacitance value according to the experimental capacitance value marked as an unworn state, where the lower-limit capacitance value is greater than the initial capacitance value, and a capacitance threshold is defined to include the upper-limit capacitance value and the lower-limit capacitance value.
It should be noted that, the in-ear device proposed by the present invention may determine the operation state of the in-ear device according to the wearing state of the in-ear device, for example, if the in-ear device is a bluetooth headset, and the bluetooth headset is in a music playing state when the bluetooth headset is in the wearing state, the music playing state will be suspended after the bluetooth headset changes from the wearing state to the non-wearing state, because the in-ear device proposed by the present invention has a function of determining the operation state according to the wearing state, the wearing detection method proposed by the present invention needs to go through many experiments to obtain many experimental capacitance values for determining the wearing state of the in-ear device, according to the above contents, the experimental capacitance values are sorted from large to small, then the experimental capacitance values arranged in the first 20% are selected from the experimental capacitance values, and the experimental capacitance values arranged in the first 20% are pre-labeled as the wearing state, which indicates that the possibility that the experimental capacitance values arranged in the first 20% correspond to the wearing state is very large, similarly, the experimental capacitance values are sorted from large to small, then the experimental capacitance values arranged in the last 20% are selected from the sorted experimental capacitance values, and the experimental capacitance values arranged in the last 20% are marked as the non-wearing state in advance, which indicates that the possibility that the experimental capacitance values arranged in the last 20% correspond to the non-wearing state is very high.
The method includes the steps of marking experimental capacitance values in advance, obtaining the experimental capacitance values marked as a wearing state in the experimental capacitance values in advance when a wearing detection program provided by the invention runs, determining an upper limit capacitance value according to the experimental capacitance values marked as the wearing state in the experimental capacitance values in advance, specifically, solving the mean value or the minimum value of the experimental capacitance values marked as the wearing state in advance, taking the solved mean value as the upper limit capacitance value, determining a lower limit capacitance value according to the experimental capacitance values marked as an unworn state in the experimental capacitance values in advance, specifically, solving the mean value or the minimum value of the experimental capacitance values marked as the unworn state in advance, and taking the solved mean value as the lower limit capacitance value.
Step S30, obtaining a target capacitance value at the current time, and determining a wearing state of the in-ear device at the current time according to a magnitude relationship between the target capacitance value and the capacitance threshold value.
It should be noted that, after determining and presetting an upper limit capacitance value and a lower limit capacitance value in a production stage, the in-ear device may enter a factory stage, so as to be used by a user, a certain time when the in-ear device is used by the user is determined to be a current time in this embodiment, a time when the in-ear device is used by the user also exists before the current time, a target capacitance value at the current time is obtained by a capacitance sensor integrated in the in-ear device, then, the obtained target capacitance value is compared with the upper limit capacitance value and the lower limit capacitance value determined and preset in the production stage by the in-ear device, and according to a magnitude relationship between the target capacitance value and a capacitance threshold value (the upper limit capacitance value and the lower limit capacitance value determined and preset in the production stage by the in-ear device), a wearing state of the in the current time of the in-ear device is determined, specifically, if the target capacitance value is greater than the upper limit capacitance value determined and preset in the production stage by the in-ear device, determining that the in-ear device is in a wearing state at the current moment; and if the target capacitance value is smaller than the lower limit capacitance value determined and preset in the production stage of the in-ear device, determining that the in-ear device is in a non-wearing state at the current moment.
Further, in a possible embodiment, the step of obtaining the target capacitance value at the current time in step S30 may be followed by:
step a1, if the target capacitance value is smaller than the initial capacitance value, adjusting the upper limit capacitance value and the lower limit capacitance value;
step 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 relationship between the target capacitance value and the capacitance threshold value.
It should be noted that the initial capacitance value is a detected capacitance value existing before the in-ear device goes out of the factory, and the initial capacitance value is very small, and 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 capacitive 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 that the upper limit capacitance value and the lower limit capacitance value of the in-ear device are synchronously adjusted down by a certain value, 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 be accurately detected; and if the target capacitance value is larger than or equal to the initial capacitance value, executing a step of determining the wearing state of the in-ear device at the current moment according to the size 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;
step a4, if the target capacitance value is smaller than the lower limit capacitance value, determining that the in-ear device is not worn at the current moment.
In this case, if the target capacitance value detected at the current time is greater than the upper-limit capacitance value determined when the in-ear device is shipped, it is determined that the in-ear device is in a wearing state at the current time; and if the target capacitance value detected at the current moment is smaller than the lower limit capacitance value determined when the in-ear device leaves the factory, determining that the in-ear device is in a non-wearing state at the current moment.
Further, in a possible embodiment, the step after the step S30 includes:
and step S40, when the in-ear device changes from the wearing state to the non-wearing state, the audio output function of the in-ear device is adjusted from an on state to an off state.
It should be noted that the in-ear device provided by the present invention may determine the operation state of the in-ear device according to the wearing state of the in-ear device, for example, if the capacitive sensor integrated in the in-ear device detects that the in-ear device is in the wearing state, the in-ear device may turn on the audio output function, that is, the in-ear device may be connected to other devices, so as to implement that the device connected to the in-ear device outputs audio through the in-ear device; if the capacitive sensor integrated in the ear insertion device detects that the ear insertion device is in a non-wearing state, the ear insertion device can close the audio output function, under the condition, the equipment connected with the ear insertion device cannot output audio through the ear insertion device, specifically, if the ear insertion device is changed from the non-wearing state to the wearing state, the connection function of the ear insertion device can be directly opened, and connection with other equipment capable of outputting audio is established, conversely, if the ear insertion device is changed from the wearing state to the non-wearing state, and before the state is changed, connection is established between the ear insertion device and other equipment capable of outputting audio, and after the state is changed, connection between the ear insertion device and other equipment capable of outputting audio is disconnected.
The wearing detection method is applied to an in-ear device integrated with a capacitance sensor, and comprises the steps of firstly obtaining an initial capacitance value and an experimental capacitance value through the capacitance sensor, and then determining a capacitance threshold value according to the initial capacitance value and the experimental capacitance value; and finally, acquiring a target capacitance value at the current moment, and determining the wearing state of the in-ear device at the current moment according to the size relation between the target capacitance value and the capacitance threshold value.
Further, referring to fig. 4, a second embodiment of the wear 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 the first embodiment, which is a refinement of step S30, and the difference between this embodiment and the above-described embodiment of the present invention is:
step S31, if the target capacitance value belongs to a buffer interval, acquiring a capacitance trend before the current time and a historical capacitance value between a target time and the current time, where a minimum value of the buffer interval is the lower limit capacitance value, a maximum value of the buffer interval is the upper limit capacitance value, and the target time is before the current time;
step S32, defining the buffer interval to include a high buffer interval and a low buffer interval, and 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 time, and adjusting the upper limit capacitance value;
step S33, if the capacitance trend is a descending trend and the historical capacitance value is in the low buffer interval, determining that the in-ear device is not worn 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 a buffer interval in this embodiment, and if the target capacitance value belongs to the buffer interval, the capacitance trend before the current time is obtained, and the capacitance trend proposed in this embodiment includes a rising trend, a falling trend, and a steady trend, and it is understood that the falling trend is shown in fig. 3, and the capacitance value before the current time is in the falling trend, and it is known that, if the target capacitance value belongs to the buffer interval, the capacitance trend before the current time and the historical capacitance value between the target time and the current time are obtained, and it is known from fig. 3 that the target time is before the current time, and then the buffer interval is defined to include a high buffer interval and a low buffer interval, and if the capacitance trend is the falling trend and the historical capacitance value is in the high buffer interval, it is determined that the in-ear apparatus is in the wearing state at the current time, and adjusting the upper limit capacitance value, wherein the upper limit capacitance value indicates that the capacitance value detected by the capacitance sensor is reduced before the target time in the process of the current time, but is not reduced to the vicinity of the lower limit capacitance value, which indicates that the in-ear device is loosened in the ear of a person, so that the capacitance value detected by the capacitance sensor is reduced.
If the capacitance trend is a descending trend and the historical capacitance value is in a low buffer interval, determining that the in-ear device is in an unworn state at the current moment, and adjusting the lower limit capacitance value, which indicates that the capacitance value detected by the capacitance sensor is reduced before the target time and in the process of the current time, and falls to the vicinity of the lower limit capacitance value, which indicates that the in-ear device is taken out of the ear of a person, so that the capacitance value detected by the capacitance sensor falls, the reason why the capacitance value detected by the capacitance sensor does not fall below the lower limit capacitance value can be that oil stain or sweat stain exists on the surface of the earphone, so that the capacitance value detected by the capacitance sensor becomes large, under the condition, the in-ear device is judged to be in an unworn state, however, the lower limit capacitance value needs to be adjusted up so that the ear insertion device taken out of the human ear can be more easily determined as the unworn state after the current time.
Further, in a possible embodiment, the steps after the step S31 further include:
step S34, if the capacitance trend is a rising 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 time, and adjusting the upper limit capacitance value;
step S35, if the capacitance trend is a rising trend and the historical capacitance value is in the low buffer interval, determining that the in-ear device is not worn at the current time, and adjusting the lower limit capacitance value.
If the capacitance trend is a rising trend and the historical capacitance value is in a 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, which indicates that the capacitance value detected by the capacitance sensor rises before the target time and in the process of the current time, and rises to near the upper limit capacitance value, which indicates that the in-ear device is placed in the human ear, causing the capacitance value detected by the capacitance sensor to rise, but due to the difference of the internal structure of the human ear, the in-ear device does not fit the auricle well, therefore, the capacitance value detected by the capacitance sensor does not rise above the upper limit capacitance value, and in this case, it is determined that the in-ear device is in a wearing state, and the upper limit capacitance value is adjusted downwards, so that the ear insertion device inserted into the ear of the human body is more convenient to judge as a wearing state after the current moment.
If the capacitance trend is a rising trend and the historical capacitance value is in a low buffer interval, determining that the in-ear device is in an unworn state at the current moment, and adjusting a lower limit capacitance value, wherein the situation indicates that the capacitance value detected by the capacitance sensor rises and only rises to the vicinity of the lower limit capacitance value in the process of the in-ear device before the target moment and to the current moment, which indicates that the in-ear device is likely to be touched by mistake, 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 under the situation, determining that the in-ear device is in an unworn state, but adjusting the lower limit capacitance value is needed, so that the in-ear device touched by mistake is more convenient to be determined to be in an unworn state after the current moment.
