Specific embodiment
Mentality of designing of the invention is: ear-sticking headphone when wearing state changes, ambient enviroment
Variation can cause the variation of capacitance, can carry out sentencing for the wearing state of ear-sticking headphone by the variation of capacitance
It is disconnected.It whether can not judge automatically in view of prior art earphone in the state worn, earphone can not be accurately controlled and played automatically

The difference of value and outer ring capacitance a reference value is as outer ring difference, and calculates interior ring capacitance current value and interior ring capacitance a reference value
After difference is as inner ring difference, comprehensive outer ring difference compared with the size of outer loop threshold and inner ring difference and inner ring threshold value it is big
Small comparison result, the wearing state of accurate judgement earphone carry out the automatic realization broadcasting of audio or answering for incoming call, without using
Family manual operation, it is convenient and efficient.To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing pair
Embodiment of the present invention is described in further detail.
Fig. 1 is a kind of process of the detection method of ear-sticking headphone wearing state provided by one embodiment of the present invention
Figure.As shown in Figure 1, this method comprises:
Step S110, configures outer ring sensor and interior ring sensor in ear-sticking headphone, outer ring sensor and interior
Ring sensor its capacitance when earphone is worn will 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 influenced to change by the temperature and appropriateness of environment.When
When earphone is worn, interior ring sensor and human skin close contact, temperature and humidity be will increase very much, so interior ring capacitance
Value increases more；Outer ring sensor contacted with human skin it is less, although being increased, increase it is less.
Step S120, corresponding outer ring sensor are stored in advance an outer ring capacitance a reference value and identify outer ring capacitance change
The inner ring of ring capacitance a reference value and mark inner ring capacitance change in one is stored in advance in outer loop threshold, and corresponding interior ring sensor
Threshold value；One wear markers position is set, in the booting of ear-sticking headphone, wear markers position is initialized as non-wearing state.
The variation of temperature and humidity can cause the variation of capacitance, can use capacitance variation judge earphone whether by
It wears.So needing to be set separately a reference value and threshold value of corresponding outer ring sensor and interior ring sensor, inner ring threshold value here
It with outer loop threshold is obtained according to a large amount of actual test data.In addition, during judging earphone wearing state, in order to
The maloperation for excluding user, the wearing state for also needing to combine earphone current while needing to be judged according to capacitance carry out
Judgement, so a wear markers position is arranged in earphone, there are two types of states for wear markers position, respectively indicate the wearing state of earphone
With non-wearing state.For example, indicating wearing state with " DON "；Non- wearing state is indicated with " DOFF ".In ear-sticking headphone
When booting, 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 variation of generation.
Step S130 carries out environmental scanning using outer ring sensor and interior ring sensor, and scanning obtains one respectively every time
Outer ring capacitance current value and an interior ring capacitance current value.Environment, which changes, causes the variation of environment temperature and humidity, in turn
Cause the variation of outer ring capacitance and inner ring capacitance, in order to judge in real time the wearing state of earphone, scans every time
When, it requires to obtain the outer ring capacitance current value and interior ring capacitance current value under earphone current state.
Then the outer ring capacitance current value and interior ring capacitance current value real-time perfoming of each scanning acquisition are operated as follows:
Step S140, calculates the difference of the outer ring capacitance a reference value of outer ring capacitance current value and storage as outer ring difference,
And in calculating the interior ring capacitance a reference value of ring capacitance current value and storage difference 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 ring difference and outer loop threshold；If outer ring 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, judge to paste
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 Yu inner ring threshold value.
Capacitance can change with the variation of environment temperature and humidity, when earphone is in wearing state, inner ring difference
It is larger, when the wearing state for judging earphone, although can be simply by comparing the big of inner ring difference and inner ring threshold value
Small judgement, but be not excluded for user and there is a situation where that inner ring difference caused by accidentally touching earphone is larger, simply by inner ring difference
It is unable to judge accurately the wearing state of earphone.For example, user when earphone is not worn, holds the ear muff of earphone,
Inner ring difference is caused greater than inner ring threshold value, earphone will be judged and be in wearing state, the automatic broadcasting for carrying out audio or oneself
Dynamic incoming call answering, but user does not use earphone at this time, will result in the excessive function of earphone and mobile terminal device in this way
Consumption reduces user experience.
In order to exclude the maloperation of user, the wearing state of accurate judgement earphone, it is contemplated that: when earphone is in wearing state
When, interior ring sensor and human skin close contact, inner ring capacitance increase more；Outer ring sensor is contacted with human skin
Less, although being increased, what is increased is less；If it is user misoperation (such as the operation for holding ear muff), draw
While the capacitance of ring sensor increases in rising, the capacitance of outer ring sensor can also be caused to increase, and hand is grabbed ear muff and made outside
Ring sensor and human skin close contact, the capacitance of outer ring sensor increase more.So the present embodiment compares first
Compared with the size of outer ring difference and outer loop threshold.If outer ring difference is greater than outer loop threshold, but may be that user in earphone does not wear shape
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 the maloperation that user grabs ear muff in the non-wearing state progress hand 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 in earphone wearing state and grabs the operation of ear muff, so being
The further maloperation for excluding user then needs 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.
It may be that earphone is in wearing shape if outer ring difference is not more than outer loop threshold and in above-mentioned comparison procedure
State, outer ring difference is smaller or the maloperation of user does not cause biggish outer ring difference, in order to further judge the pendant of earphone
Wear state, it is contemplated that earphone is in wearing state, and inner ring difference is larger, so need further to read the inner ring threshold value of storage,
Compare the size of inner ring difference Yu inner ring threshold value.
Step S160 illustrates that strictly user is in earphone wearing state progress hand if inner ring difference is greater than inner ring threshold value
It is smaller that the operation or the current state of earphone for grabbing ear muff meet the outer ring difference in wearing state, the biggish feelings of inner ring difference
Condition then judges that ear-sticking headphone is wearing state, and wear markers position is labeled as wearing state；If inner ring difference is little
In inner ring threshold value, then do not meet earphone be in wearing state outer ring difference it is smaller, the larger situation of inner ring difference, judge paste ear
Formula headphone is non-wearing state, and wear markers position is labeled as non-wearing state.
As it can be seen that variation of the present invention by the capacitance of test earphone inner ring and outer rings, excludes maloperation, accurate judgement ear
The wearing state of machine, and then the broadcasting or pause of audio are realized automatically, and whether auto-pickup is sent a telegram here, and is grasped manually without user
Make, it is convenient and efficient, excess power consumption is prevented, user experience is enhanced.
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 changes will occur for the temperature and humidity of ambient enviroment, and capacitor a reference value will be sent out
Changing recycles preset outer ring a reference value and inner ring a reference value to be judged, just not can guarantee and sentence during judgement
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, earphone is in
When non-wearing state, interior ring capacitance current value is 60, then current inner ring difference is 10, less than 30, then judges that earphone is not wear
State the result is that correct；But if environment has occurred and that variation, inner ring a reference value should be 90, and earphone is in and does not wear
The interior ring capacitance current value obtained when state is 100, if calculating inner ring difference is further according to the inner ring a reference value 50 of storage
50, it is greater than 30, then judges that earphone is wearing state the result is that incorrect, because inner ring a reference value at this time has occurred that
Variation.So in the case where in order to guarantee that environment changes, also can accurate judgement earphone wearing state, need the moment according to
The variation of environment updates outer ring a reference value and inner ring a reference value, and in one embodiment of the invention, method shown in FIG. 1 is into one
Step includes: when judging ear-sticking headphone is non-wearing state, and the outer ring capacitance obtained using last time scanning is current
The outer ring capacitance a reference value and interior ring capacitance a reference value that value and interior ring capacitance current value update storage respectively.
Outer ring capacitance a reference value and interior ring capacitance benchmark when judging ear-sticking headphone is wearing state, to storage
Value is without updating.Because the state that wear markers are is wearing state when earphone is in wearing state, judged when
It waits, either which kind of situation, requires the judgement for carrying out inner ring difference, as long as earphone is in wearing state, environment causes
Inner ring a reference value variation or to be far smaller than the variation of human skin bring inner ring difference, a reference value is without more
Newly, smaller to the influence of judging result.
For above-mentioned steps, if earphone is not physics shutdown, interior ring sensor and outer ring sensor can all carry out constantly
Environmental scanning is simultaneously judged, will also result in the excess power consumption of earphone or terminal device in this way, in order to reduce excess power consumption.At this
In one embodiment of invention, method shown in FIG. 1 further include: a variety of connection types of corresponding ear-sticking headphone, are outer

Then mode obtains sweep time further according to the connection type of earphone, use phase to control interior ring sensor and outer ring sensor
The trace interval answered carries out environmental scanning.
