Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a schematic flowchart illustrating a method for detecting a wearing state of a headset according to an embodiment of the present application, where, referring to fig. 1, the headset according to the embodiment of the present application is divided into a plurality of headset detection areas according to a contact condition between a human ear and the headset in a normal wearing state, and the method for detecting a wearing state of the headset includes steps S110 to S130 as follows:
in step S110, the area contact values detected in each earphone detection area are acquired.
According to the embodiment of the application, a plurality of earphone detection areas are set in advance according to different structures of different earphones and contact conditions of the earphones and human ears, as shown in fig. 2, a schematic diagram of the earphones in a normal wearing state is provided, and as shown in fig. 3, a schematic diagram of the earphones in the wireless earphones is provided. Because different types of earphones are in different contact conditions with human ears, and different parts of the same type of earphones are in different contact conditions with the human ears, how to set or divide the earphone detection area is specifically determined, and a person skilled in the art can flexibly select the earphone detection area according to the actual condition without specific limitation.
When the wearing state of the earphone is detected, the area contact value detected by the sensor in each earphone detection area can be acquired first and used as the basis for subsequently judging the wearing state of the earphone. The area contact value here may refer to a capacitance value detected by the capacitance sensor in each of the earphone detection areas, or may refer to a pressure value detected by the pressure sensor in each of the earphone detection areas. The wearing state of the earphone is detected by taking the area as a unit, so that the conditions of misjudgment and the like of the sensor can be avoided to a certain extent, and the detection precision is improved.
Step S120, comparing each area contact value with an area detection threshold of the corresponding earphone detection area.
The embodiment of the application determines the area detection threshold of each earphone detection area in advance to be used as a standard for judging the wearing state of the earphone. Specifically, the earphone can be tested for many times before the earphone leaves the factory, and the contact values of the areas obtained in the testing process are counted to obtain the area detection threshold values corresponding to the earphone detection areas. And then comparing the obtained area contact value of each area with the area detection threshold value corresponding to each area respectively to determine the wearing state of the earphone.
Step S130, determining the wearing state of the earphone according to the comparison result, wherein the wearing state of the earphone comprises a worn state and an unworn state, and the worn state comprises a normal wearing state and an abnormal wearing state.
The wearing state of the earphone in the embodiment of the present application may specifically include a worn state and an unworn state, where the worn state may be understood as that the earphone is in contact with the human ear, and the unworn state may be understood as that the earphone is not in contact with the human ear or the contact degree is negligible. Further, according to different degrees of contact, the worn state can include a normal wearing state and an abnormal wearing state, the normal wearing state can be understood as a state in which the earphone is in full contact with the human ear and the fall-off or the like does not occur, and the abnormal wearing state can be understood as a state in which the earphone is not in full contact with the human ear or the contact is not tight and the fall-off or the like easily occurs.
According to the obtained comparison result, whether the current earphone is in a worn state or not can be determined, if the earphone is in the worn state, whether the earphone is in a normal wearing state or an abnormal wearing state is determined, and whether the current wearing posture of the user has risks or not can be determined according to the detection result of the wearing state.
The embodiment of the application can detect whether the user wears the earphone or not through the divided earphone detection areas, can also automatically detect whether the posture that the user wears the earphone is correct or not, and further can prevent the situations that the wearing is not tight or the earphone is not completely plugged into the ear, the earphone drops or is lost and the like.
In an embodiment of the present application, each earphone detection area is provided with a multi-channel capacitive sensor, and the acquiring an area contact value detected in each earphone detection area includes: for each earphone detection area, acquiring a multi-channel capacitance value detected by a corresponding multi-channel capacitance sensor; and calculating the average value of the multi-channel capacitance values as the area contact value of the detection area of the earphone.
This application embodiment can adopt multichannel capacitive sensor to detect the capacitance value, compares in traditional single channel capacitive sensor, and multichannel capacitive sensor is more sensitive to the capacitance value change of each position, and then can detect more accurate regional contact value, provides the basis for follow-up earphone wearing state of confirming. In specific implementation, a multi-channel capacitance sensor may be respectively disposed for each earphone detection area, each channel may measure a capacitance value, each area is taken as a statistical unit, the capacitance values measured by each channel in the area may be summed and averaged to serve as an area contact value of the area, and of course, in addition to a statistical manner of summing and averaging, a person skilled in the art may also determine the area contact value by using other statistical methods, which are not listed herein.
It should be noted that, in the embodiment of the present application, in addition to the capacitance sensor may be used to detect the contact condition between the earphone and the human ear, other types of sensors such as a pressure sensor may also be used to detect the contact pressure between each detection area on the earphone and the human ear to determine the wearing state, that is, the earphone wearing state detection process in the embodiment of the present application is also applicable to other types of sensors.
In one embodiment of the present application, the region detection threshold includes a normal wearing threshold and an abnormal wearing threshold, and the normal wearing threshold and the abnormal wearing threshold are determined by: testing multi-channel capacitance values detected in each earphone detection area under the condition that the earphones are normally worn, and taking the average value of the capacitance values of each channel corresponding to each earphone detection area as a normal wearing threshold value of each earphone detection area; and determining the abnormal wearing threshold value of each earphone detection area according to the normal wearing threshold value of each earphone detection area and a preset proportion coefficient.
The area detection threshold of the embodiment of the application may specifically include a normal wearing threshold and an abnormal wearing threshold, the normal wearing threshold may be used as a criterion for determining whether the earphone is in a normal wearing state, and the abnormal wearing threshold may be used as a criterion for determining whether the earphone is in an abnormal wearing state. The threshold may be obtained by testing the earphone for multiple times before the earphone leaves a factory, for example, for a normal wearing threshold, the capacitance values detected in each channel at each time may be added and averaged; for the abnormal wearing threshold, since the capacitance value detected under the abnormal wearing condition is usually smaller than the capacitance value detected under the normal wearing condition, and the corresponding abnormal wearing threshold is also smaller than the normal wearing threshold, the normal wearing threshold may be multiplied by a scaling factor smaller than 1 to serve as the abnormal wearing threshold, and the scaling factor may be flexibly set according to the actual situation, for example, may be 0.5.
In an embodiment of the present application, the area detection threshold includes a normal wearing threshold and an abnormal wearing threshold, and the determining the wearing state of the headset according to the comparison result includes: when the area contact value of any one earphone detection area is larger than the normal wearing threshold value corresponding to the earphone detection area, determining that the earphone wearing state is the worn state; and when the area contact value of each earphone detection area is smaller than the abnormal wearing threshold value corresponding to the earphone detection area, determining that the earphone wearing state is the non-wearing state.
When the wearing state of the earphone is detected, if the area contact value of any one earphone detection area is larger than the normal wearing threshold value corresponding to the earphone detection area, it is indicated that at least one earphone detection area of the earphone is in contact with the human ear at present, that is, the earphone is in the worn state, and as for the wearing state corresponding to the contact degree, whether the wearing state belongs to the normal wearing state of sufficient contact or the abnormal wearing state of untight contact can be further judged. Otherwise, when the area contact values of all the earphone detection areas are smaller than the abnormal wearing threshold corresponding to the area, it is indicated that all the detection areas of the earphone are not in contact with the human ears at present, and the earphone can be considered to be in an unworn state at this time.
In an embodiment of the present application, in a case where it is determined that the headset wearing state is the worn state, the determining a headset wearing state according to the comparison result includes: if the area contact value of each earphone detection area is larger than the normal wearing threshold value, determining that the earphone wearing state is the normal wearing state; and if the area contact value of any one earphone detection area is larger than the abnormal wearing threshold value and smaller than the normal wearing threshold value, determining that the earphone wearing state is the abnormal wearing state.
As described above, when the area contact value of at least one earphone detection area is greater than the normal wearing threshold corresponding to the earphone detection area, it is indicated that the earphone is in the worn state, and at this time, it may be further determined whether the earphone is in the normal wearing state or the abnormal wearing state. Specifically, if the area contact value of each earphone detection area is greater than the normal wearing threshold value, the earphone is in sufficient contact with the human ear, and the earphone is determined to be in a normal wearing state; if the area contact value of any earphone detection area is larger than the abnormal wearing threshold value and smaller than the normal wearing threshold value, it indicates that at least one earphone detection area does not achieve sufficient contact with human ears, and the earphone is determined to be in an abnormal wearing state.
In one embodiment of the application, the zone detection threshold comprises a normal wear threshold, the earphone detection zone comprises a first detection zone on a side close to the ear canal, a third detection zone on a side remote from the ear canal, and a second detection zone located between the first detection zone and the third detection zone, the method further comprising: determining whether to send an early warning prompt according to the wearing state of the earphone; the determining whether to send an early warning prompt according to the wearing state of the earphone comprises: when the area contact value detected by the third detection area is lower than the normal wearing threshold value, determining to send a low-level early warning reminder; when the area contact value detected by the second detection area is lower than the normal wearing threshold value, determining to send a middle-level early warning reminder; and when the area contact values detected by the first detection area, the second detection area and the third detection area are all smaller than the normal wearing threshold value, determining to send advanced early warning prompt.
Because different types of earphones have different structures and correspondingly arranged earphone detection areas, the embodiment of the application takes the earplug type earphone in fig. 3 as an example for description, and when the earplug type earphone is worn, the contact tightness between the surface of the earphone and the ears of a person has regional difference, so that the earphone is suitable for using the technical scheme provided by the application. As shown in fig. 3, the earphone detection area of the embodiment of the present application may include three annular areas, where the first detection area is located at a side close to the ear canal, and can determine whether to contact with the ear according to the size of the area contact value, and can be directly used to detect the wearing state of the earphone and whether to be worn tightly. The contour diameter of the second detection area is the largest, so that the area is a key detection area of the degree of close fit between the human ear and the earphone, namely when the area contact value of the second detection area is smaller than the normal wearing threshold value, the earphone is worn loosely, and the earphone does not fall off only by means of contact between other areas of the earphone and the human ear. The third detection area represents the area outside the earphone on the side far away from the ear canal, and when the threshold value detected by the third detection area is lower than the wearing threshold value, the wearing condition of the earphone can be detected to be changed at the first time.
In order to avoid the situation that the earphone drops or is lost due to untight wearing, the embodiment of the application can also determine whether to send the warning prompt to the user according to the wearing state of the earphone, for example, if the earphone is in an abnormal wearing state of untight wearing, the warning prompt is given to the user by broadcasting the voice built in the earphone, so that the user can correct or adjust the wearing state of the earphone.
Different early warning levels can be set in advance according to detection results of different earphone detection areas. In specific implementation, as shown in fig. 4, before the wearing state detection is performed, initialization is performed to obtain the area detection threshold of each detection area, and then the area contact value of each detection area is read in real time by a Micro Controller Unit (MCU). Then, state judgment is carried out, if the area contact values of the three detection areas are detected to be higher than a normal wearing threshold value, the current detection area is considered to be in a normal wearing state, and early warning reminding is not needed; when the third detection area is also kept away from the earphone of duct and is less than normally wearing the threshold value when the capacitance value that detects in the outside region, it indicates that the earphone mainly relies on inboard second detection area and the contact of first detection area and people's ear, although wear still closely, still have certain risk of wearing this moment, consequently can get into low-level early warning mode to voice broadcast through the built-in voice data of earphone once reminds. When the capacitance value that detects the second detection area is less than normally wearing the threshold value, explain that the earphone is in wearing untight unusual wearing state, only leans on partial position to block the earphone, has produced in fact not hard up, can get into the middle level early warning mode this moment to carry out the voice broadcast warning that is interrupted many times through the built-in voice data of earphone. When the three detection areas are detected to be all lower than the normal wearing threshold value, the earphone is probably dropped from the ear at any time, the earphone enters an advanced early warning mode at the moment, and the user is informed to adjust the wearing state in time through uninterrupted voice broadcasting. For the warning reminding modes corresponding to the different warning levels, a person skilled in the art can flexibly set the warning reminding modes according to actual conditions, and the warning reminding modes are not specifically limited herein.
For the three detection areas, the three detection areas are sequentially as follows from far to near according to the far-near relation with the auditory canal of the human ear: a third detection area, a second detection area, and a first detection area. Generally speaking, when the area contact value of the third detection area on the outermost side exceeds the normal wearing state threshold value, it indicates that the outermost side of the earphone has fully contacted with the human ear, and it may be considered that the second detection area and the first detection area located on the inner side also have fully contacted with the human ear, that is, the area contact values of the three areas are all greater than the normal wearing state threshold value, at this time, the real-time detection and monitoring may be continued on the area contact values of the areas without performing the warning prompt.
In an embodiment of the application, the determining whether to send an early warning reminder according to the wearing state of the headset includes: when the wearing state of the earphone is the abnormal wearing state, determining to send an early warning prompt; and when the wearing state of the earphone is switched from the abnormal wearing state to the normal wearing state, interrupting the early warning prompt.
According to the embodiment of the application, the area contact value of each detection area can be read in real time through the MCU, and then the wearing state of the earphone can be detected and monitored in real time. And once the earphone is detected to enter or be in an abnormal wearing state, an early warning prompt is sent to the user, so that the damage or loss caused by the falling of the earphone is avoided. And after the wearing state of the user is adjusted to be the normal wearing state according to the reminding, the early warning reminding can be interrupted, and excessive interference to the user is avoided.
It should be noted that, although the earphone mentioned in the above embodiments is mainly directed to an earplug earphone, for other types of earphones, the earphone can also be adapted to the wearing state detection for other types of earphones by adaptively adjusting the technical solution of the present application. For example, for the wearing state detection of the headset, the corresponding sensors may be provided and the headset detection area may be divided according to the specific configuration of the headset, for example, the headset is usually in contact with the auricle of the human ear through the ear pad of the headset, so that the sensors may be provided and the plurality of detection areas may be divided at the corresponding contact positions of the headset according to the contact condition of the headset with the human ear in the normal wearing state to perform the wearing state detection.
