Embodiment
Below in conjunction with the accompanying drawing in the present embodiment, be clearly and completely described the technical scheme in the present embodiment, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
In order to solve exist in prior art when terminal plugged earphone, the implementation that its audio frequency is play is single, and the audio frequency that cannot meet different application scene exports the problem of demand, the invention provides a kind of method that audio frequency being applied to terminal is play.
Wherein, this terminal can be the electronic equipment that can carry out audio frequency broadcasting arbitrarily and possess receiver J-Horner on hardware, and thus this terminal both can be the handheld terminal such as mobile phone, panel computer PAD, MP3; Also can be the fixed terminals such as PC.
As shown in Figure 1, the method comprises:
S101: if detect that described terminal is connected with earphone, then obtain the driving current value of each sound channel of described earphone, described driving current value is after described terminal is connected with described earphone, the current value that described each sound channel obtains.
Wherein, in the present embodiment, the earphone of indication is mainly insert earphone, both can be three-section earphone, also can be four-section type headset, both can be the earphone of band microphone function, also can for only possessing the earphone etc. of acoustic function.In the present embodiment, the terminal of indication is connected with earphone and refers to that earphone inserts terminal device by the receiver J-Horner on terminal device, and can realize the function of earphone or be referred to as earphone and insert and put in place.
Whether in the implementation procedure of this step, first needing to detect has earphone to insert terminal.At present, there is the technical scheme whether multiple Test earphone inserts terminal, have a contact inside the earphone jack as terminals such as mobile phones, when earphone inserts, this contact by short circuit, and then can detect that earphone inserts.Whether this detection has earphone to insert the implementation procedure of terminal can with reference to prior art.
If detect that earphone is inserted into terminal device, then the earphone power amplifier unit of terminal device can be respectively each sound channel (general earphone comprises L channel and R channel) power supply of earphone to drive earphone.Inventor finds under study for action, and user wears certain sound channel and do not wear compared with this sound channel, when wearing, this sound channel air pressure is larger, and earphone power amplifier unit exports same voltage drive signals, and the vibration amplitude of this sound channel is less, the resistance of this sound channel is less, and thus the drive current of this sound channel is larger.Based on this principle, in this step, need the driving current value of each sound channel obtaining earphone in real time or at regular intervals, to judge whether user wears certain sound channel according to this driving current value.
It should be noted that, in the present embodiment, the sound channel of indication and the receiver of earphone are one-to-one relationship, and also namely general earphone comprises two receivers, and wherein, L channel is to there being L channel receiver, and R channel is to there being R channel receiver.
S102: the described driving current value of each sound channel is compared with corresponding predetermined current threshold set, obtains the comparative result corresponding with each sound channel, the corresponding predetermined current threshold set of each described sound channel.
In the present embodiment, this predetermined current threshold set can have multiple implementation, as follows respectively:
This predetermined current threshold set for only to comprise a predetermined current threshold, then, when the driving current value of certain sound channel obtained is greater than this predetermined current threshold, can show that user wears this sound channel; When the driving current value of certain sound channel obtained is less than this predetermined current threshold, show that user does not wear this sound channel.
This predetermined current threshold set can also be comprise one for representing that user does not wear certain sound channel time all electric currents may the range of current of values, then when the driving current value of certain sound channel obtained is positioned at this range of current, show that user does not wear this sound channel, otherwise show that user wears this sound channel; In like manner, this predetermined current threshold set can also be comprise one for representing that user wears certain sound channel time all electric currents may the range of current of values, then when the driving current value of certain sound channel obtained is positioned at this range of current, show that user wears this sound channel, otherwise show that user does not wear this sound channel.
This predetermined current threshold set can also be comprise two different range of current, one of them range of current is that all electric currents of user when wearing this sound channel may the range of current that formed of values, and another range of current is that all electric currents of user when not wearing this sound channel may the range of current that formed of values; Then by judging the range of current at the driving current value place of certain sound channel obtained, obtaining user and whether wearing this sound channel.
The predetermined current threshold that the different sound channels of earphone are corresponding may identical also possibility difference.
On the basis of driving current value obtaining each sound channel, this step is that the process compared, what obtain each sound channel wears result by predetermined current threshold set corresponding with this sound channel for the driving current value of each sound channel obtained.
S103: according to the comparative result corresponding with each sound channel, obtains earphone and wears result.
This step is that on the basis of the comparative result corresponding with each sound channel obtained at S102, the comprehensively wear condition of each sound channel, what obtain earphone further wears result.
General earphone comprises L channel and R channel, then the possibility of result worn by the earphone obtained by this step is following four kinds of situations: only wear L channel, only wear R channel, left and right acoustic channels is all worn, left and right acoustic channels all do not wear (non-wear headphones).
S104: choose the audio frequency way of output wearing result corresponding with described earphone and export described sound signal.
Although insert earphone, the result of wearing of earphone has multiple possibility.Thus, the output of this step sound intermediate frequency signal wears the different and difference to some extent of result because of earphone.
When user only wears L channel, then by means of only L channel output audio signal; When user only wears R channel, then by means of only R channel output audio signal; When user has not only worn L channel but also has worn R channel, then can normal output audio signal; When user did not both wear L channel, when not wearing again R channel (non-wear headphones), stop output or the output audio signal by other means of sound signal, as exported by receiver or loudspeaker.
The method that a kind of audio frequency that the embodiment of the present invention provides is play, when detecting that terminal is connected with earphone, obtains the driving current value of each sound channel of earphone; Again the driving current value of each sound channel is compared with corresponding predetermined current threshold set, obtain the comparative result corresponding with each sound channel, and obtain earphone further and wear result; And then choose and wear audio frequency way of output output audio signal corresponding to result with earphone, with in prior art when terminal plugged earphone, the implementation fixed single that its audio frequency is play is compared, the present invention wears result by obtaining earphone according to the driving current value of each sound channel, wear result according to earphone again and choose the corresponding audio frequency way of output, can realize selecting different way of output output audio signals according to the wear condition of earphone, the audio frequency that thus can meet different application scene exports demand.
Further, in a kind of implementation of step S102, predetermined current threshold set comprises the first range of current and the second range of current, this first range of current is the range of current of user when wearing corresponding sound channel, and this second range of current is the range of current of user when not wearing corresponding sound channel.
The first range of current in the present embodiment and the second range of current are and are obtained by many experiments, and the first range of current and the second range of current be without common factor.In experimentation, the impact of the various factors such as the environment residing for earphone, test the driving current value got may be different at every turn.Also, namely, when user wears certain sound channel, the driving current value of this sound channel in varied situations, its value is floated within the scope of certain, thus, in the present embodiment, when adopting the first range of current to represent that user wears certain sound channel, this sound channel can institute's likely value of obtainable driving current value; In like manner, in the present embodiment, the second range of current for user do not wear this sound channel time, this sound channel can institute's likely value of obtainable driving current value.
Thus, as shown in Figure 2, step S102 can be refined as following step S201.
S201: the driving current value of each sound channel is compared with the first range of current and the second range of current respectively, obtains the range of current at the driving current value place of each sound channel.
Specifically, this step is the process of the range of current at the driving current value place of searching each sound channel.In the process of searching, both can for having searched the first range of current and whether the second range of current comprises this driving current value simultaneously; Also can for first to search the first range of current, when driving current value is not in the first range of current, tentatively can determine that the range of current at this driving current value place is the second range of current, again by the second range of current and this driving current value are compared confirmation, obtain the ultimate current scope at driving current value place; In like manner, also can first search the second range of current, then search the first range of current.
When this driving current value is neither in the first range of current, also not when the second range of current, can think that exception worn by earphone, preserve this driving current value simultaneously, for revising the first range of current and the second range of current.
Accordingly, step S103 can be refined as following step S202 and step S203.
S202: if the range of current at the driving current value place of at least one sound channel is the first range of current, to be then user wears described earphone described sound channel described at least one that result worn by the described earphone obtained.
When the range of current at the driving current value place of L channel is the first range of current, the earphone obtained is worn result for user and is worn L channel; When the range of current at the driving current value place of R channel is the second range of current, the earphone obtained is worn result and is not worn R channel for user; When the range of current at the driving current value place of left and right acoustic channels is all in the first range of current, the earphone obtained is worn result for user and has been worn left and right acoustic channels.
S203: if the range of current at the driving current value place of all sound channels of earphone is the second range of current, then the earphone obtained is worn result and do not worn described earphone for user.
The comparative result that this step obtains did not wear R channel for user has not both worn L channel yet, was the non-wear headphones of user yet.
In the another kind of implementation of step S102, above-mentioned predetermined current threshold set comprises pre-set current value.
This pre-set current value is that the user obtained by test of many times is not worn certain sound channel and wears the critical value of certain sound channel, when the driving current value obtained is greater than this critical value, shows that user wears this sound channel, otherwise, show that user does not wear this sound channel.
Thus, as shown in Figure 3, step S102 can be refined as following step S301.
S301: the driving current value of each sound channel compared with corresponding pre-set current value, obtains the comparative result corresponding with each sound channel.
Accordingly, step S103 can be refined as following step S302 and step S303.
S302: if the driving current value of at least one sound channel is greater than pre-set current value, to be then user wears described earphone described sound channel described at least one that result worn by the earphone obtained.
The comparative result that this step obtains may L channel, user only wear R channel, user has not only worn L channel but also worn R channel for user only wears.
S303: if the driving current value of all sound channels of earphone is all less than pre-set current value, then the earphone obtained is worn result and do not worn described earphone for user.
The comparative result that this step obtains did not wear R channel for user has not both worn L channel yet, was the non-wear headphones of user yet.
The predetermined threshold value set that this method provides only comprises a pre-set current value, and the procurement process of this pre-set current value is simple, and compared to the method that Fig. 2 provides, its comparison procedure simplifies further.
Wear on the basis of result what obtain earphone, for different application scenarioss, as shown in Figure 4, step S104 can be refined as following step S401 to S403.
S401: if described earphone to wear result be user wears described earphone described sound channel described at least one, then export described sound signal by described sound channel described at least one.
S402: if result worn by described earphone do not wear described earphone for user, and described sound signal is from multimedia application, then stop the output of described sound signal or export described sound signal by the loudspeaker of described terminal.
This multimedia application is the audiovisual applications on terminal device.When the non-wear headphones of user and sound signal from audiovisual applications, be specifically music file or video file time, in a kind of implementation of this step, in order to avoid the waste of electricity, stop the output of this sound signal; In addition, in the another kind of implementation of this step, in order to ensure the continuity of the output of sound signal, output audio signal is continued by the loudspeaker of terminal itself.
S403: if result worn by described earphone do not wear described earphone for user, and described sound signal is from speech business, then export described sound signal by the loudspeaker of described terminal.
Due to the angle from Consumer's Experience, compared to other audio services, speech business possesses higher priority.Thus in this step, when the non-wear headphones of user and sound signal from speech business time, have new incoming call by the loudspeaker output audio signal of terminal with reminding user.
It should be noted that, when the non-wear headphones of user, different broadcast modes can be adopted for different sound signals as described in step S402 and step S403, also can for adopt identical broadcast mode after user is arranged voluntarily, as being no matter the sound signal from speech business or other business, to arbitrary sound signal, as long as the situation of the non-wear headphones of user, can be set to all be play by the loudspeaker of terminal.
Further, because different earphone internal drivings has difference, need to determine the predetermined current threshold set corresponding with this earphone when therefore using new earphone, wear result for use in what judge earphone, this deterministic process needs user to participate in.When this predetermined current threshold set comprises the first range of current and the second range of current, as shown in Figure 5, this process comprises:
S501: receive the first instruction triggered when user wears sound channel.
In the present embodiment in predetermined threshold value set-determination process because needs user participates in, thus need first to load track selecting interface.The first range of current of corresponding sound channel and the deterministic process of the second range of current is carried out according to the selection result of user.As when user selects L channel, this deterministic process is the deterministic process of the first range of current that L channel is corresponding and the second range of current; After the first range of current corresponding to L channel and the second range of current have been determined, the first range of current of R channel, the deterministic process of the second range of current are started.
Simultaneously, after user have selected corresponding sound channel, load and be used for the sound channel that reminding user does not wear its selection, trigger the interface of beginning first range of current simultaneously for user, and when user triggers this instruction, start the deterministic process of the first range of current of this sound channel.
S502: according to described first instruction, output audio signal, gathers the driving current value of described sound channel every Preset Time, determine described first range of current corresponding with described sound channel.
When after the instruction receiving user, terminal device can automatically by earphone output audio signal, and gather the driving current value of this sound channel at regular intervals, by analyzing the driving current value of multi collect, get maximal value wherein and minimum value, obtain the first range of current that this sound channel is corresponding.
S503: receive the second instruction triggered when user does not wear sound channel.
This step can refer step S501, and wherein the second instruction is for triggering the deterministic process of the second range of current.
S504: according to described second instruction, output audio signal, gathers the driving current value of described sound channel every Preset Time, determine described second range of current corresponding with described sound channel.
This step can refer step S502.
It should be noted that, the deterministic process of this range of current, also for first to determine the second range of current, then can determine the first range of current, thus can be first perform step S503 and step S504, then perform step S501 and step S502.
In addition, when this predetermined current threshold set only comprises pre-set current value, its implementation procedure also can with reference to above-mentioned steps S501 to step S504, and specifically, this process comprises:
511: receive the first instruction triggered when user wears sound channel.
512: according to described first instruction, output audio signal, gathers the driving current value of described sound channel every Preset Time.
513: receive the second instruction triggered when user does not wear this sound channel.
514: according to described second instruction, output audio signal, gathers the driving current value of this sound channel every Preset Time.
515: the driving current value that this sound channel gathered when the driving current value that this sound channel gathered when analysis user wears sound channel is corresponding and user do not wear this sound channel is corresponding, determine predetermined current threshold.
Due between the current value that gathers when the current value that gathers when user does not wear a certain sound channel and user wear this sound channel without occuring simultaneously, and when current value when user wears sound channel does not wear this sound channel, current value is larger.Thus can take the current value between the minimum value in the current value gathered when maximal value in the current value gathered when a certain sound channel is not worn at family and user wear this sound channel, this current value is defined as predetermined current threshold.
Also first step 513 and step 514 be can perform in this process, then step 511 and step 512 performed.
It should be noted that, the deterministic process of the predetermined current threshold set of indication in the present embodiment, the deterministic process that also can participate in reference to this user.The deterministic process participated in this user unlike, participant can be the scientific research personnel in mobile phone production run.Such as, mobile-phone manufacturers are in the process of producing mobile phone, and be generally also equipped with earphone corresponding with it, then, when this mobile phone dispatches from the factory, the predetermined current threshold set stored is corresponding with this earphone, and its deterministic process needs the participation of scientific research personnel; When user in use changes earphone, can be participated in by user, redefine the predetermined current threshold set corresponding with new earphone.
