It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Exemplary method
As shown in fig. 1, an embodiment of the present invention provides an earphone in-ear detection method, which includes the following steps:
step S100, obtaining in-ear detection data, and judging whether the in-ear detection data meets in-ear detection conditions.
In this embodiment, the method for detecting the earphone insertion into the ear is applied to a terminal, where the terminal may be an earphone or an earphone box connected to the earphone; the present embodiment takes an earphone as an example, and describes the earphone in-ear detection method.
In the present embodiment, the earphones include an in-ear TWS (True Wireless Stereo) earphone and a half-in-ear TWS earphone; moreover, the earphone has an in-ear detection function and an out-ear detection function; wherein, the in-ear detection function means that the earphone is equipped with a corresponding sensor (e.g. a photosensitive sensor and/or a capacitance detection sensor, etc.), and the sensor detects whether the head (i.e. the position of the earphone) of the earphone enters the ear of the user, so as to automatically sense whether the earphone is in a wearing (in-ear) state; the ear outgoing detection function is to automatically sense whether the earphone is not worn (in-ear) or not; in the actual use process of the earphone, if a user needs to pause the played content due to some things, at the moment, any one of the two earphones is taken down, the currently played content of the earphone can be automatically paused by detecting the current state of the earphone, and the currently paused content of the earphone can be automatically played when the earphone is subsequently worn, so that the power consumption of the earphone during the non-use period is reduced, and the actual use time of the earphone is effectively prolonged.
In order to improve the accuracy of the in-ear detection of the earphone, the in-ear state of the earphone is detected by adopting an optical detection and/or a capacitance detection mode to acquire in-ear detection data, and the error judgment phenomenon in the in-ear detection is reduced by combining an audio detection mode, so that the accuracy of the in-ear detection of the earphone is improved.
In the implementation of this embodiment, it is necessary to acquire in-ear detection data through a sensor in the earphone, and determine whether the in-ear detection data meets in-ear detection conditions; the in-ear detection data is data detected by the earphone in an in-ear state, and the data comprises light data and/or capacitance detection values; the light ray data is in-ear detection data acquired by a photosensitive sensor of the earphone, and whether the ambient light of the earphone meets an ear detection condition or not can be judged by acquiring the light ray data, so that the in-ear state of the earphone is detected in an optical detection mode; the capacitance detection value is in-ear detection data acquired by a capacitance detection sensor of the earphone, and whether the capacitance value of the earphone meets an ear detection condition can be judged by acquiring the capacitance detection value, so that the in-ear state of the earphone is detected in a capacitance detection mode; when judging whether the in-ear detection data meets in-ear detection conditions or not, and when the in-ear detection data is light data, the in-ear detection conditions are as follows: the light ray data is smaller than a preset light ray threshold value; when the in-ear detection data is a capacitance detection value, the in-ear detection condition is as follows: and the capacitance detection value exceeds the range of a preset capacitance value.
Before the implementation of the method for detecting the in-ear condition of the earphone of this embodiment, that is, before the in-ear detection data is obtained, a preset light threshold of the in-ear detection condition needs to be set; when the preset light threshold is set, in the factory stage of the earphone, the detection threshold of the photosensitive sensor (i.e., the first sensor) in the earphone in the in-ear state is set in a manner of optical detection, and the detection threshold of the photosensitive sensor is the preset light threshold of the in-ear detection condition in this embodiment.
When the preset light threshold value is set, a plurality of groups of light data of the earphone in an in-ear state can be acquired firstly; the light data comprises illuminance, and the preset light threshold comprises a preset illuminance threshold; when the plurality of sets of light ray data are acquired, the plurality of sets of light ray data can be acquired through a plurality of pairs of earphones or can be acquired through the same pair of earphones; for example, 10 sets of light data are acquired by 10 pairs of headphones, or 10 sets of light data may be acquired by 1 pair of headphones.
In another implementation manner of this embodiment, when the preset light threshold is determined, the light may be obtained based on light of an external environment; for example, multiple sets of light data are acquired by one or more pairs of headphones in the same light environment.
After the plurality of sets of light ray data are obtained, setting a light ray threshold value for light ray detection according to the plurality of sets of light ray data; specifically, the obtained multiple sets of light ray data may be compared to obtain a maximum value in the multiple sets of light ray data, and then the preset light ray threshold value is set according to the obtained maximum value, so as to use the preset light ray threshold value as a detection threshold value of the photosensor of the earphone; wherein the maximum value in the plurality of sets of light ray data is the maximum illumination value in the plurality of sets of light ray data; for example, if the current ambient light illuminance is 400Lux, and the maximum illuminance value is 80% of the current ambient light illuminance, the preset light threshold is 320 Lux.
That is, in one implementation manner of the present embodiment, step 100 includes the following steps before:
001, acquiring multiple groups of light ray data of the earphone in an in-ear state, which are acquired by a first sensor;
step 002, determining a maximum value in the plurality of sets of light ray data, and setting a preset light ray threshold value of the in-ear detection condition according to the maximum value.
In this embodiment, before implementing the method for detecting the in-ear condition of the earphone of this embodiment, that is, before acquiring the in-ear detection data, a preset capacitance range of the in-ear detection condition needs to be set; when the preset capacitance range is set, in a factory stage of the earphone, a capacitance sensing range of a capacitance detection sensor (namely a second sensor) in the earphone in an in-ear state is set; the capacitance range of the capacitance detection sensor is a preset capacitance range of the earphone in-ear detection condition.
In this embodiment, the detection principle of the capacitance detection sensor is as follows: the capacitance detection sensor may convert a change in a measured quantity (e.g., a measured quantity of size, pressure, distance, etc.) into a change in capacitance; it is understood that the distance between the earphone of the earphone and the ear of the user is measured in this embodiment, and whether the earphone is in the in-ear state is determined by the detected capacitance value.
When the preset capacitance value range is set, a plurality of groups of capacitance detection values of the earphone in an in-ear state can be acquired; the plurality of groups of capacitance detection values can be a plurality of groups of capacitance detection values acquired by a plurality of pairs of earphones, or a plurality of groups of capacitance detection values acquired by the same pair of earphones; for example, 10 sets of capacitance detection values are acquired by 10 pairs of earphones, or 10 sets of capacitance detection values are acquired by 1 pair of earphones.
In another implementation manner of this embodiment, when determining the preset capacitance range, the preset capacitance range may be obtained based on the same distance; for example, multiple sets of capacitance measurements are acquired by one or more pairs of headphones in the same phantom.
After the plurality of groups of capacitance detection values are obtained, a capacitance value range for capacitance detection can be set according to the obtained plurality of groups of capacitance detection values; specifically, the obtained multiple groups of capacitance detection values may be compared to obtain a maximum capacitance detection value and a minimum capacitance detection value in the multiple groups of capacitance detection values; then, setting the range of the preset capacitance value according to the maximum capacitance detection value and the minimum capacitance detection value; based on different capacitor models, the preset capacitance value ranges are different; in this embodiment, the preset capacitance value range may be 50uF to 60 uF.
That is, in an implementation manner of the present embodiment, step 100 further includes the following steps:
step 003, acquiring a plurality of groups of capacitance detection values of the earphone in an in-ear state, which are acquired by a second sensor;
step 004, determining a maximum capacitance detection value and a minimum capacitance detection value in the plurality of groups of capacitance detection values;
and 005, determining a preset capacitance range of the in-ear detection condition according to the maximum capacitance detection value and the minimum capacitance detection value.
In this embodiment, after the preset light threshold and/or the preset capacitance range is set, in-ear detection data can be obtained in an actual in-ear detection process, and whether the in-ear detection data meets an in-ear detection condition is determined; when the in-ear detection data is acquired, the in-ear state of the earphone can be detected through the detection mode of the photosensitive sensor and/or the detection mode of the capacitive sensor so as to preliminarily detect whether the earphone is worn in the ear of the user currently.
When the current state of the earphone is preliminarily detected, any one detection mode of the photosensitive sensor and the detection mode of the capacitance sensor can be adopted; of course, two detection modes, namely the detection mode of the photosensitive sensor and the detection mode of the capacitive sensor, can be adopted to improve the accuracy of the initial detection.
In this embodiment, when the detection mode of the photosensitive sensor is adopted, the light data in the earphone can be collected through the photosensitive sensor; the light data are light data of the area where the photosensitive sensor is located, and the light data of the area where the photosensitive sensor is located depend on the structure of the earphone; by acquiring the light data, whether the light data is smaller than the preset light threshold value or not can be judged, and if the light data is smaller than the preset light threshold value, the light data can be judged to meet the in-ear detection condition, so that the current state of the earphone is preliminarily judged to be in-ear state; it is worth mentioning that when the detection mode of the photosensitive sensor is adopted, the in-ear detection condition is as follows: and the light data detected by the photosensitive sensor is smaller than the preset light threshold value.
In addition, when the earphone is in the earphone box (the earphone box is closed), the detected light data is also smaller than the preset light threshold, and at this time, in order to avoid the occurrence of a misjudgment phenomenon, it is further necessary to exclude the case where the earphone is in a box-shaped state, that is, when the earphone box detects that the earphone is in the earphone box, it is determined that the light data does not satisfy the in-ear detection condition.
Specifically, when the detection mode of the photosensitive sensor is adopted, the light flux irradiating a preset area in the earphone can be collected through the photosensitive sensor arranged in the earphone cavity; wherein the luminous flux is the total amount of light irradiated in the preset area; the preset area is a setting area of the photosensitive sensor; for example, an earpiece region of the headset, in which the light sensitive sensor is arranged.
When the luminous flux of the preset region is collected, the area of the preset region can be obtained, wherein the preset region and the area thereof can be determined according to the structure of the earphone; for example, the area of the earpiece region of the headset; of course, the area of the preset area can also be a parameter value set in the earphone in a user-defined mode.
After the luminous flux of the preset area is collected, the illuminance in the earphone can be calculated according to the luminous flux and the area; wherein the illuminance is obtained by dividing the luminous flux by the area of the preset area; it is understood that the luminous flux is a unit of light measurement in a unit area to reflect the light intensity in a certain area; after the illuminance in the earphone is obtained through calculation, the illumination environment of the photosensitive sensor of the earphone can be preliminarily judged by judging whether the illuminance is smaller than the preset illuminance threshold value; for example, the preset light threshold is 320Lux, the calculated ambient light illuminance is 300Lux, and at this time, it may be preliminarily determined that the light environment of the photosensor in the earphone is a dark environment, and the earphone is currently in a wearing state.
That is, in an implementation manner of this embodiment, step S100 specifically includes the following steps:
step S110, acquiring light data collected by the first sensor;
step S120, judging whether the light ray data is smaller than the preset light ray threshold value;
step S130, if the light data is smaller than the preset light threshold, determining that the light data satisfies the in-ear detection condition.
The embodiment is characterized in that the luminous flux irradiating a preset area in the earphone is collected, the illuminance in the earphone can be calculated according to the luminous flux and the area, and then the illumination environment of the photosensitive sensor in the earphone is preliminarily judged according to the illuminance and the preset illuminance threshold value so as to preliminarily detect whether the earphone is currently worn in the ear of the user.
In this embodiment, when the detection mode of the capacitance sensor is adopted, a capacitance detection value of a preset capacitance in the earphone needs to be acquired; the preset capacitor is a detection capacitor in the capacitive sensor, the capacitive sensor can dynamically detect the distance between the earphone and the ear of the user, the detected distance is converted into a corresponding capacitance value, and the distance between the earphone and the ear of the user is dynamically displayed by the change of the capacitance value; the distance that capacitive sensor can be accurate to 0.1mm, through acquireing capacitive sensor's capacitance value in the earphone can improve the earphone goes into the ear and detects the precision.
Specifically, when the detection mode of the capacitance sensor is adopted, the preset capacitance range needs to be acquired; the preset capacitance value range can be 50 uF-60 uF; whether the capacitance detection value exceeds the preset capacitance value range or not can be judged by obtaining the preset capacitance value range, if the capacitance value of the capacitance sensor in the earphone exceeds the preset capacitance value range, the capacitance detection value is judged to meet the in-ear detection condition, and at the moment, the earphone is worn in the ear of the user currently; for example, if the capacitance value of the capacitive sensor is 70uF, the headset is currently worn in the ear of the user.
It is worth mentioning that, when the detection mode of the capacitance sensor is adopted, the in-ear detection condition is as follows: and the capacitance detection value detected by the capacitance sensor exceeds the preset capacitance value range.
That is, in an implementation manner of this embodiment, step S100 specifically includes the following steps:
step S140, acquiring light data collected by the first sensor;
step S150, judging whether the capacitance detection value exceeds the preset capacitance value range;
step S160, if the capacitance detection value exceeds the preset capacitance value range, determining that the capacitance detection value satisfies the in-ear detection condition.
In the embodiment, the current state of the earphone is detected by the capacitance value of the capacitive sensor by acquiring the capacitance value of the capacitive sensor, so that whether the earphone is currently worn in the ear of the user is preliminarily detected by the capacitance detection value of the capacitive sensor.
As shown in fig. 1, in an implementation manner of the embodiment of the present invention, the method for detecting the earphone insertion into the ear further includes the following steps:
and step S200, if the in-ear detection data meets the in-ear detection condition, playing audio source data and collecting in-ear audio data in the earphone.
In this embodiment, if the light data or the capacitance detection value meets an in-ear detection condition (that is, the light data is smaller than the preset light threshold, or the capacitance detection value exceeds the preset capacitance range), it is further required to determine whether the earphone is completely worn in the ear of the user in an audio comparison manner; and when audio comparison is carried out, acquiring in-ear audio data in the earphone, and simultaneously comparing the acquired audio data with the audio data in an in-ear state, so as to determine whether the earphone is completely worn in the ear of the user according to a comparison result.
Specifically, before acquiring in-ear audio data in the earphone, audio source data for in-ear detection needs to be acquired; the audio source data is preset audio data used for detecting an in-ear state; it is understood that the audio source data is standard audio data played in a state where the headphones are in the ear.
After the audio source data are acquired, a preset microphone of the earphone is turned on, and the audio source data are played through a loudspeaker in the earphone; at this time, the audio signal collected by the preset microphone in the earphone is the in-ear audio data.
When the earphone is provided with two or more noise reduction microphones, the noise reduction microphones of the earphone can be divided into a feedforward microphone (namely FF mic) and a feedback microphone (namely FB mic); the feedforward microphone is arranged on a microphone (namely the outer side of an earphone head of the earphone) at one side far away from the ear of a user, and is mainly used for acquiring noise of an external environment and then providing a feedforward active noise reduction function by utilizing a reverse noise reduction principle; the feedback microphone is arranged at a microphone close to one side of the ear of the user (namely the inner side of the earphone head of the earphone), and is mainly used for acquiring noise inside the earphone shell and then providing a feedback active noise reduction effect by utilizing a reverse noise reduction principle.
In this embodiment, the preset microphone is the feedback microphone (i.e., FB mic); when the audio source data is played, audio signals played by a loudspeaker in an earphone shell are collected through the feedback microphone, and then the in-ear audio data can be obtained; wherein the audio source data may be an alert tone of a specific frequency; for example, a cue tone with a cue duration of 5 seconds is presented once per second.
That is, in an implementation manner of this embodiment, the step S300 specifically includes the following steps:
step S210, if the light data or the capacitance detection value meets the in-ear detection condition, acquiring the audio source data;
step S220, the audio source data is played through the loudspeaker of the earphone, and the audio signal during the playing of the loudspeaker is collected through a preset microphone of the earphone, so that the in-ear audio data is obtained.
The present embodiment plays audio source data through a speaker in the headset, and collects audio data in the cavity of the headset using a feedback microphone to further determine whether the headset has been completely worn in the ear of the user in an audio contrast manner.
As shown in fig. 1, in an implementation manner of the embodiment of the present invention, the method for detecting the earphone insertion into the ear further includes the following steps:
step S300, comparing the in-ear audio data with the audio source data, and determining the in-ear state of the earphone according to the comparison result.
In this embodiment, after the in-ear audio data is obtained, the in-ear audio data may be compared with the audio source data, and the in-ear state of the earphone is determined according to the comparison result, so that under the preliminary detection of the detection data of the photosensitive sensor and/or the capacitive sensor, whether the earphone has been completely worn in the ear of the user is determined by using an audio comparison method, so as to improve the in-ear detection accuracy of the earphone.
Specifically, when comparing the in-ear audio data with the audio source data, the in-ear audio data may be compared with the audio source data to obtain a difference between the in-ear audio data and the audio source data; the audio frequency comparison mode can adopt a sound wave comparison mode, namely the ear-entering audio data and the audio source data are led into the same audio track, and the sound wave difference value of the ear-entering audio data and the audio source data at the same time point or time period is obtained by comparing sound wave signals at the same time point or time period.
After the difference value between the in-ear audio data and the audio source data is obtained, acquiring a preset difference value range, and judging whether the difference value between the in-ear audio data and the audio source data is within the preset difference value range; the preset difference range is set in the following mode: the earphone is in an ear-out state in advance, audio data in the ear-out state (namely, the audio data collected by the feedback microphone in the ear-out state) is collected, the collected audio data is compared with the audio source data, and a difference value between the ear-out audio data and the audio source data is obtained (the audio comparison mode can adopt the sound wave comparison mode), and the difference value between the ear-out audio data and the audio source data is a preset difference value; because the audio source data and the ear-out audio data are audio data in a certain time period, the difference value between the ear-out audio data and the audio source data has a maximum value and a minimum value, and the preset difference value range can be determined by acquiring the maximum value and the minimum value; for example, under a certain noise environment, the maximum value and the minimum value of the difference between the ear-emerging audio data and the audio source data are 7db and 2db, respectively, and the preset difference range may be 2db-7 db.
When judging whether the difference value between the in-ear audio data and the audio source data is within the preset difference value range, if the difference value between the in-ear audio data and the audio source data is within the preset difference value range, judging that the current state of the earphone is in an in-ear state; if the difference value is not within the preset difference value range, judging that the current state of the earphone is in an ear-out state; wherein the condition that the difference value between the in-ear audio data and the audio source data is within the preset difference value range is as follows: and under the condition of the same time point, the difference value between the sound wave signal of the in-ear audio data and the sound wave signal of the audio source data is within the preset difference value range.
That is, in an implementation manner of this embodiment, the step S400 specifically includes the following steps:
step S310, comparing the in-ear audio data with the audio source data to obtain a difference value between the in-ear audio data and the audio source data;
step S320, acquiring a preset difference value range, and judging whether the difference value between the in-ear audio data and the audio source data is within the preset difference value range;
step S330, if the difference value between the in-ear audio data and the audio source data is within the preset difference value range, judging that the current state of the earphone is in an in-ear state;
step S340, if the difference between the in-ear audio data and the audio source data is not within the preset difference range, determining that the current state of the earphone is an out-of-ear state.
