A kind of earphone control method for playing back schematic flow sheet that Fig. 2 provides for disclosure embodiment, this earphone control method for playing back can be applied to the terminal 1 in Fig. 1, and as shown in Figure 2, this earphone control method for playing back comprises the steps:

Step S100: obtain the state parameter information of earphone when playing be connected with described terminal.

In the disclosed embodiments, the information that state parameter information can gather for the transducer be arranged in earphone or terminal, or the information extracted in the information gathered at transducer.Wherein, when sensor setting is on earphone, the obtain manner of state parameter information is determined by the connected mode of earphone and terminal, specifically comprises: if earphone and terminal wired connection, then terminal obtains state parameter information by the holding wire of frames connecting with headphone and terminal; If earphone is connected with terminal wireless, then terminal obtains state parameter information by the communication module be arranged in terminal and earphone.

The object obtaining the state parameter information of earphone when playing is the using state being judged earphone by state parameter information, and that is, the state parameter information in disclosure embodiment is the state parameter information that can reflect earphone using state.Such as, audio-frequency information, acceleration information, gyroscope information, light sensing information, magnetic field induction information, pressure sensitive information, distance induction information, upset induction information, temperature sense information etc. can be selected.

Step S200: judge whether described earphone is not according to described state parameter information and wear using state.

Because state parameter information is in the disclosed embodiments the state parameter information that can reflect earphone using state, therefore, the using state of earphone can be judged according to the state parameter information obtained in step S100.Such as, by the state parameter information of acquisition and pre-conditionedly to compare (pre-conditioned be not in condition when wearing using state for earphone), if the state parameter information obtained meets pre-conditioned, then judging that earphone is not in wears using state; If the state parameter information obtained does not meet pre-conditioned, then judge that earphone is in and wear using state.

When described earphone be not in wear using state time, perform step S300; Otherwise process ends.

Step S300: control described terminal and stop to described earphone output audio signal.

In the disclosed embodiments, control that described terminal stops can playing for the media player pause on control terminal to described earphone output audio signal, the quiet or audio signal transmission wire road between disconnected end and earphone of media player on control terminal, the disclosure does not limit this, but its effect reached is earphone no longer received audio signal, earphone suspends to be play.That is, in the disclosed embodiments, when judge earphone be not in wear using state time, can automatically control earphone suspend play, user need not perform again other operation, easy to use.

As shown in Figure 3, it can comprise the following steps at step S100 embodiment illustrated in fig. 2 another embodiment of the present disclosure:

Step S101: receive the voice signal that the microphone in described terminal or on earphone collects when described earphone is play;

In the disclosed embodiments, in terminal or earphone be provided with microphone.Under normal circumstances, earphone be in wear using state time, due to earphone and terminal distant, the microphone in terminal or on earphone can not collect earphone play voice signal; But, after user takes earphone, usually earphone is placed on from the not far position of terminal, such as, terminal is mobile phone, usually earphone is placed on the side of mobile phone after user takes earphone, and the microphone now in terminal or on earphone can collect the voice signal that earphone is play.Based on this principle, the voice signal that the microphone in the disclosed embodiments in terminal or on earphone collects is as the basis for estimation of earphone using state.

Step S102: the state parameter information of frequency as described earphone extracting described voice signal.

Under normal circumstances, the environment not absolute squelch that user is residing when using earphone, ambient noise (musical sound etc. as in vehicle whistle sound, television acoustics sound, bar) can cause certain interference to the voice signal of microphone collection.If judge that user takes earphone when microphone collects outside noise, obviously can cause erroneous judgement, affect Consumer's Experience.Therefore, also need to distinguish that this voice signal is voice signal or the outside noise of earphone broadcasting after microphone collects voice signal.

Frequency is one of attribute important in voice signal, and it can reflect the bulk information comprised in voice signal, such as, can be known the song of music by the frequency analyzing one section of music; The content of talk can be known by the frequency analyzing one section of dialogue.Therefore, in the disclosed embodiments, extract the state parameter information of frequency as earphone of voice signal, and then differentiation microphone collects voice signal or outside noise that voice signal is earphone broadcasting, gets rid of the interference of outside noise.

On the basis of abovementioned steps S101 and S102, in disclosure embodiment, step S200 embodiment illustrated in fig. 2 can comprise the following steps:

Step S201: the frequency obtaining the audio signal of described terminal plays;

In above-mentioned steps S102, the object extracting the frequency of voice signal is to judge whether the voice signal that microphone collects is the voice signal that earphone is play.In order to realize this object, needing the frequency of the frequency of the voice signal collected by microphone and the audio signal of terminal plays to contrast, therefore, in the disclosed embodiments, obtaining the frequency of the audio signal of terminal plays.

Step S202: judge whether the frequency of described audio signal and the frequency of described voice signal match;

Ideally, if the voice signal of microphone collection is entirely the voice signal that earphone is play, then the frequency of audio signal should be mated completely with the frequency of voice signal, but under actual conditions, the voice signal that microphone collects can adulterate some noises unavoidably, causes the frequency of audio signal can not mate completely with the frequency of voice signal.For this situation, a matching degree threshold value is set in the disclosed embodiments, determines that when the frequency of audio signal and the frequency of voice signal are within matching degree threshold value the frequency of audio signal and the frequency of voice signal match.

When the frequency of described audio signal and the frequency of described voice signal match, perform step S203, otherwise, process ends.

Step S203: determine that described earphone is not in and wear using state.

In the disclosed embodiments, when the frequency of audio signal and the frequency of voice signal match, show that the microphone in terminal or on earphone collects the voice signal of earphone broadcasting, and then determine that earphone is placed near terminal after being taken by user, earphone is not in wears using state.

After step S203, perform above-mentioned steps S300, and then realize when user takes earphone, automatic control terminal stops to earphone output audio signal.

As shown in Figure 4, it is on basis embodiment illustrated in fig. 3, and above-mentioned steps S100 can also comprise the following steps for another embodiment of the present disclosure:

Step S103: the state parameter information of amplitude as described earphone extracting described voice signal.

Amplitude can reflect the size of the voice signal that microphone collects, and voice signal more large amplitude is larger; The less amplitude of voice signal is less.Under normal circumstances, after user takes earphone, the voice signal that microphone collects becomes large, and its reason is: after user takes earphone on the one hand, be placed on by earphone near terminal, the voice signal that microphone is collected that diminishes of the distance between earphone and microphone becomes large; After on the other hand user takes earphone, the voice signal that the earplug on earphone makes microphone collect without the obstacle (during user's wear headphones, ear can play certain barrier effect to voice signal) of voice signal becomes large.Based on this principle, in the disclosed embodiments using the Rule of judgment one of of the amplitude of voice signal as earphone using state, therefore, extract the state parameter information of amplitude as described earphone of described voice signal.

Using the amplitude of voice signal after state parameter information, when the frequency of described audio signal and the frequency of described voice signal match, the step S200 that disclosure embodiment provides can also comprise:

Step S204: judge whether the amplitude of current extracted described voice signal is more than or equal to default amplitude threshold with the difference of the amplitude of the last described voice signal extracted.

In the disclosed embodiments, the frequency of audio signal and the frequency of voice signal match and may there are two kinds of situations: one is that user takes earphone, and microphone collects the voice signal that earphone is play; Another kind is that user does not take earphone, but the bad voice signal causing microphone still can collect faint earphone playing of the sound soundproof effect that is comparatively large or earplug play due to earphone.

If when the frequency of audio signal and the frequency of voice signal match, namely determine that user takes earphone, erroneous judgement to a certain degree obviously can be brought.For this problem, introduce amplitude size in the disclosed embodiments and judge, namely judge whether the amplitude of current extracted described voice signal is more than or equal to default amplitude threshold with the difference of the amplitude of the last described voice signal extracted.

When the difference of described amplitude is more than or equal to default amplitude threshold, performs above-mentioned steps S203, determine that described earphone is not in and wear using state; Otherwise, process ends.

That is, in the disclosed embodiments, only have and meet " frequency of audio signal and the frequency of voice signal match " and " amplitude of current extracted voice signal is more than or equal to default amplitude threshold with the difference of the amplitude of the last voice signal extracted " condition simultaneously, just determine that earphone is not in and wear using state, improve the accuracy that earphone using state is judged.

In the disclosed embodiments, whether be in from audio frequency and amplitude two aspect determination earphones and wear using state, when the frequency of audio signal and the frequency of voice signal match, and the amplitude of current extracted described voice signal is when being more than or equal to default amplitude threshold with the difference of the amplitude of the last described voice signal extracted, determine that earphone is not in and wear using state, avoid the sound soundproof effect that is comparatively large or earplug play due to earphone bad and the erroneous judgement that causes, improve the accuracy of judgement.

It is to be noted; above-described embodiment is only an exemplary description; those skilled in the art can adjust accordingly according to the order of actual conditions to above-mentioned determining step; such as; first can judge whether the amplitude of current extracted described voice signal is more than or equal to default amplitude threshold with the difference of the amplitude of the last described voice signal extracted; judge whether the frequency of described audio signal and the frequency of described voice signal match, and it all should be within protection range of the present disclosure again.

As shown in Figure 5, it can comprise the following steps at step S100 embodiment illustrated in fig. 2 another embodiment of the present disclosure:

Step S111: obtain the spatial position data that gyroscope that described earphone is arranged in two earplugs collects.

In the disclosed embodiments, earphone respectively establishes a gyroscope in two earplugs, the spatial position data that acquisition gyroscope collects is as the initial data of computing mode parameter information.

Step S112: the angle angle between the axis calculating two earplugs on described earphone according to described spatial position data is as described state parameter information.

Fig. 6 is not in a kind of scene schematic diagram when wearing use for a kind of earphone that disclosure embodiment provides, as shown in Figure 6, earphone be not in wear use time, due to the characteristic of earphone self, make between the axis of two earplugs on earphone in certain angle α, but when earphone is worn on the head of user, on earphone, two earplugs are tending towards parallel, i.e. angle between the axis of two earplugs becomes large.Based on this principle, can by the basis for estimation of the angle angle between the axis of two earplugs on earphone as earphone using state.

As shown in Figure 5, disclosure embodiment can comprise the following steps at step S200 embodiment illustrated in fig. 2:

Step S211: whether the angle angle between the axis judging two earplugs on described earphone is less than or equal to predetermined angle threshold value;

According to the above-mentioned description to Fig. 6, when user's wear headphones, on earphone two earplugs axis between angle become large, therefore, in the disclosed embodiments, set an angle threshold according to the state of earphone when not wearing use.Such as, when earphone be in do not wear using state time, on earphone two earplugs axis between angle α=135 °, when earphone be in wear using state time, on earphone two earplugs axis between angle α=170 °, then can choose numerical value between above-mentioned two angles as angle threshold, as 140 °, 145 ° or 150 ° etc.By calculate in step S112 gained to two earplugs axis between angle angle and this angle threshold compare, and then determine the using state of earphone.

When described angle angle is less than or equal to predetermined angle threshold value, perform step S212; Otherwise, process ends.

Step S212: determine that described earphone is not in and wear using state.

In the disclosed embodiments, due to the characteristic of earphone self, when user's wear headphones, on earphone two earplugs axis between angle become large; When user takes earphone, on earphone two earplugs axis between angle diminish.Therefore, when described angle angle is less than or equal to predetermined angle threshold value, determines that described earphone is not in and wear using state.

After step s 212, perform above-mentioned steps S300, and then realize when user takes earphone, automatically control described terminal and stop to described earphone output audio signal.

As shown in Figure 7, it can comprise the following steps at step S100 embodiment illustrated in fig. 2 another embodiment of the present disclosure:

Step S121: obtain the range data between two earplugs that range sensor that described earphone is arranged collects;

As shown in Figure 6, due to the characteristic of earphone self, when user's wear headphones, the distance on earphone between two earplugs can become large; After user takes earphone, the distance on earphone between two earplugs can diminish.Therefore, can by the basis for estimation of the distance on earphone between two earplugs as earphone using state.In the disclosed embodiments, earphone is provided with range sensor, the range data between two earplugs that acquisition range sensor collects.

Step S122: using described range data as described state parameter information.

In the disclosed embodiments, the range data between two earplugs collected by range sensor is as state parameter information.

As shown in Figure 7, disclosure embodiment can comprise the following steps at step S200 embodiment illustrated in fig. 2:

Step S221: judge whether described range data is less than or equal to predeterminable range threshold value;

According to the above-mentioned description to Fig. 6, when user's wear headphones, the distance on earphone between two earplugs becomes large, therefore, in the disclosed embodiments, sets a distance threshold according to the state of earphone when not wearing use.Such as, when earphone be in do not wear using state time, the distance on earphone between two earplugs is 10cm; When earphone be in wear using state time, the distance on earphone between two earplugs is 20cm, then can choose numerical value between above-mentioned two distances as distance threshold, as 14cm, 15cm or 16cm etc.Range data between two earplugs collected by step S121 middle distance transducer and this distance threshold compare, and then determine the using state of earphone.

When described range data is less than or equal to predeterminable range threshold value, perform step S222; Otherwise, process ends.

Step S222: determine that described earphone is not in and wear using state.

In the disclosed embodiments, due to the self-characteristic of earphone, when user's wear headphones, the distance on earphone between two earplugs becomes large; When user takes earphone, the distance on earphone between two earplugs diminishes.Therefore, when the range data between two earplugs that range sensor collects is less than or equal to distance threshold, determines that described earphone is not in and wear using state.

After step S222, perform above-mentioned steps S300, and then realize when user takes earphone, automatic control terminal stops to earphone output audio signal.

As shown in Figure 8, it can comprise the following steps at step S100 embodiment illustrated in fig. 2 another embodiment of the present disclosure:

Step S132: using described pressure data as described state parameter information.

After user takes earphone, be placed on by earphone on loading end, the pressure sensor on earphone contacts with loading end and then produces pressure signal; When user's wear headphones, earphone departs from loading end, and the pressure sensor on earphone is separated with loading end, and pressure signal disappears.Based on this principle, in the disclosed embodiments, the pressure data collected by pressure sensor is as state parameter information.

As shown in Figure 8, the step S200 of disclosure embodiment embodiment described in Fig. 2 can comprise the following steps:

Step S231: judge whether described pressure data is more than or equal to default pressure threshold;

After user takes earphone, pressure sensor contacts with loading end, and the pressure data that pressure sensor collects becomes large, and therefore, in the disclosed embodiments, the pressure data that when contacting with loading end according to earphone, pressure sensor collects sets a pressure threshold.Such as, when earphone is placed on loading end, ideally, the pressure data that pressure sensor collects is 20N, then one can be selected to be less than the numerical value of these desired pressure data as pressure threshold, such as, can select 10N or 15N etc.The pressure data collected by pressure sensor in step S131 and this pressure threshold compare, and then determine the using state of earphone.

When described pressure data is more than or equal to default pressure threshold, perform step S232; Otherwise, process ends.

Step S232: determine that described earphone is not in and wear using state.
