Specific embodiment
Mentality of designing of the invention is：Ear-sticking headphone when wearing state changes, surrounding environment
Change can cause the change of capacitance, and the wearing state that ear-sticking headphone can be carried out by the change of capacitance is sentenced
It is disconnected.In view of prior art earphone cannot automatic decision whether in the state worn, it is impossible to accurate control earphone is played automatically
Audio or auto-pickup are sent a telegram here, and reduce Consumer's Experience；Or the broadcasting of earphone automatic pause audio cannot be accurately controlled, cause ear
The problem of the excess power consumption of machine and mobile terminal device.The present invention configures outer ring sensor and inner ring in ear-sticking headphone
Sensor carries out environmental scanning respectively, to obtain outer shroud electric capacity currency and inner ring electric capacity currency, calculates outer shroud electric capacity current
The difference of value and outer shroud electric capacity a reference value is used as outer shroud difference, and calculates inner ring electric capacity currency with inner ring electric capacity a reference value
After difference is as inner ring difference, comprehensive outer shroud difference compares with the size of outer loop threshold and inner ring difference is big with inner ring threshold value
Small result of the comparison, the accurate wearing state for judging earphone, carries out being automatically obtained the broadcasting of audio or answering for incoming call, without use
Family is manually operated, convenient and swift.To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing pair
Embodiment of the present invention is described in further detail.
A kind of flow of the detection method of ear-sticking headphone wearing state that Fig. 1 is provided for one embodiment of the invention
Figure.As shown in figure 1, the method includes：
Step S110, configures outer ring sensor and interior ring sensor, outer ring sensor and interior in ear-sticking headphone
Ring sensor its capacitance when earphone is worn can increase.
The outer ring sensor and interior ring sensor of the present embodiment can be arranged respectively at the outer of the ear muff of ear-sticking headphone
The capacitance of ring and inner ring, outer ring sensor and interior ring sensor is influenceed to change by the temperature and appropriateness of environment.When
When earphone is worn, interior ring sensor and human body skin close contact, temperature and humidity can increase a lot, so inner ring electric capacity
Value increase is more；Outer ring sensor is less with contact human skin, although increased, but increase is less.
Step S120, the outer ring sensor of correspondence prestores an outer shroud electric capacity a reference value and identifies outer shroud capacitance change
Ring sensor prestores the inner ring of an inner ring electric capacity a reference value and mark inner ring capacitance change in outer loop threshold, and correspondence
Threshold value；One wear markers position is set, when ear-sticking headphone is started shooting, wear markers position non-wearing state is initialized as.
The change of temperature and humidity can cause the change of capacitance, it is possible to use the change of capacitance judge earphone whether by
Wear.So needing to set a reference value and threshold value of the outer ring sensor of correspondence and interior ring sensor, inner ring threshold value here respectively
Obtained according to substantial amounts of actual test data with outer loop threshold.In addition, during earphone wearing state is judged, in order to
The maloperation of user is excluded, it is necessary to also need to be carried out with reference to the current wearing state of earphone while judgement according to capacitance
Judge, so setting wear markers position in earphone, wear markers position there are two states, the wearing state of earphone is represented respectively
With non-wearing state.For example, representing wearing state with " DON "；Non- wearing state is represented with " DOFF ".In ear-sticking headphone
During start, wear markers position is initialized as non-wearing state, when the wearing state of earphone changes, the shape of wear markers position
State also can be with the corresponding change of generation.
Step S130, environmental scanning is carried out using outer ring sensor and interior ring sensor, and scanning every time obtains one respectively
Outer shroud electric capacity currency and an inner ring electric capacity currency.Environment changes and causes the change of environment temperature and humidity, and then
Cause the change of outer shroud capacitance and inner ring capacitance, in order to the wearing state in real time to earphone judges, scan every time
When, it is required for obtaining the outer shroud electric capacity currency and inner ring electric capacity currency under earphone current state.
Then the outer shroud electric capacity currency and inner ring electric capacity currency that scanning is obtained every time are proceeded as follows in real time：
Step S140, calculates outer shroud electric capacity currency with the difference of the outer shroud electric capacity a reference value of storage as outer shroud difference,
And calculate inner ring electric capacity currency with the difference of the inner ring electric capacity a reference value of storage as inner ring difference, so as to corresponding threshold
Value is compared.
Step S150, reads the outer loop threshold of storage, compares the size of outer shroud difference and outer loop threshold；If outer shroud difference is big
In outer loop threshold, then the wearing state of wear markers position is first read；If wear markers position is labeled as non-wearing state, patch is judged
Ear formula headphone is non-wearing state；If wear markers position is labeled as wearing state, the inner ring threshold of storage is further read
Value, compares the size of inner ring difference and inner ring threshold value.
Capacitance can change with the change of environment temperature and humidity, when earphone is in wearing state, inner ring difference
It is larger, when the wearing state of earphone is judged, although can be big with inner ring threshold value simply by inner ring difference is compared
Small judgement, but it is not excluded for user and there is the larger situation of inner ring difference that false touch earphone causes, simply by inner ring difference
The wearing state of earphone cannot accurately be judged.For example, user is not when earphone is worn, the ear muff of earphone is held,
Inner ring difference is caused more than inner ring threshold value, earphone will be judged and be in wearing state, carry out automatically audio broadcasting or from
Dynamic incoming call answering, but now user does not use earphone, so will result in the excessive work(of earphone and mobile terminal device
Consumption, reduces Consumer's Experience.
In order to exclude the maloperation of user, the accurate wearing state for judging earphone, it is contemplated that：When earphone is in wearing state
When, interior ring sensor and human body skin close contact, inner ring capacitance increase are more；Outer ring sensor and contact human skin
It is less, although to have increased, but increase is less；If user misoperation (such as holding the operation of ear muff), draws
While the capacitance of ring sensor increases in rising, the capacitance of outer ring sensor can be also caused to increase, and hand is grabbed ear muff and is made outward
Ring sensor and human body skin close contact, the capacitance increase of outer ring sensor it is more.So, the present embodiment compares first
Compared with outer shroud difference and the size of outer loop threshold.If outer shroud difference is more than outer loop threshold, but is probably that user does not wear shape in earphone
State carries out the operation that hand grabs ear muff, it is also possible to which user carries out the operation that hand grabs ear muff in earphone wearing state, so judging
Before earphone wearing state, the wearing state of wear markers position is first read；If wear markers position is labeled as non-wearing state, say
Bright is that user carries out the maloperation that hand grabs ear muff in the non-wearing state of earphone, judges that ear-sticking headphone is non-wearing state；
If wear markers position is labeled as wearing state, it may be possible to which user carries out hand and grabs the operation of ear muff in earphone wearing state, so being
The further maloperation for excluding user, then need further to read the inner ring threshold value of storage, compares inner ring difference and inner ring threshold
The size of value, judges the wearing state of earphone in terms of interior ring sensor.
And, in above-mentioned comparison procedure, if outer shroud difference is not more than outer loop threshold, be probably earphone be in wear shape
State, outer shroud difference is smaller, or the maloperation of user does not cause larger outer shroud difference, in order to determine whether the pendant of earphone
Wear state, it is contemplated that earphone is in wearing state, inner ring difference is larger, so need further to read the inner ring threshold value of storage,
Compare the size of inner ring difference and inner ring threshold value.
Step S160, if inner ring difference is more than inner ring threshold value, illustrates that strictly user carries out hand in earphone wearing state
It is smaller that the operation or the current state of earphone for grabbing ear muff meet the outer shroud difference in wearing state, the larger feelings of inner ring difference
Condition, then judge that ear-sticking headphone is wearing state, and wear markers position is labeled as into wearing state；If inner ring difference is little
In inner ring threshold value, then do not meet earphone be in wearing state outer shroud difference it is smaller, the larger situation of inner ring difference judges patch ear
Formula headphone is non-wearing state, and wear markers position is labeled as into non-wearing state.
It can be seen that, the change of the capacitance that the present invention passes through test earphone inner ring and outer rings excludes maloperation, accurately judges ear
The wearing state of machine, and then the broadcasting or pause of audio are automatically obtained, and whether auto-pickup is sent a telegram here, and is grasped manually without user
Make, it is convenient and swift, excess power consumption is prevented, strengthen Consumer's Experience.
If ear-sticking headphone is in non-wearing state, but being not excluded for earphone can move with user, week
Collarette border can change at any time, it is meant that the temperature and humidity of surrounding environment can all change, and electric capacity a reference value will be sent out
Changing, during judgement, recycles default outer shroud a reference value and inner ring a reference value to be judged, cannot just ensure to sentence
Disconnected accuracy.For example, the inner ring a reference value of storage is 50, inner ring threshold value is 30, then environment does not change, and earphone is in
During non-wearing state, inner ring electric capacity currency is 60, then current inner ring difference is 10, less than 30, then judges that earphone is not wear
The result of state is correct；But if environment has occurred and that change, inner ring a reference value should be 90, and earphone is in and does not wear
The inner ring electric capacity currency obtained during state is 100, if further according to the inner ring a reference value 50 of storage, calculating inner ring difference is
50, more than 30, then judge that earphone is that the result of wearing state is incorrect, because inner ring a reference value now has occurred that
Change.So in the case of in order to ensure that environment changes, also can accurately judge the wearing state of earphone, it is necessary to the moment according to
The change of environment updates outer shroud a reference value and inner ring a reference value, and in one embodiment of the invention, the method shown in Fig. 1 enters one
Step includes：When it is non-wearing state to judge ear-sticking headphone, the outer shroud electric capacity obtained using last time scanning is current
Value and inner ring electric capacity currency update the outer shroud electric capacity a reference value and inner ring electric capacity a reference value of storage respectively.
When it is wearing state to judge ear-sticking headphone, to the outer shroud electric capacity a reference value and inner ring electric capacity benchmark that store
Value is not updated.Because earphone be in wearing state when, the state that wear markers are is wearing state, judged when
Wait, either which kind of situation, be required for carrying out the judgement of inner ring difference, as long as earphone is in wearing state, its environment causes
Inner ring a reference value change or to be far smaller than the inner ring difference that human body skin brings change, a reference value do not carry out more
Newly, the influence to judged result is smaller.
For above-mentioned steps, if earphone is not physics shutdown, interior ring sensor and outer ring sensor can all be carried out constantly
Environmental scanning simultaneously judged, the excess power consumption of earphone or terminal device is so will also result in, in order to reduce excess power consumption.At this
In one embodiment of invention, the method shown in Fig. 1 also includes：Various connected modes of correspondence ear-sticking headphone, are outer
