Fig. 2 is illustrated that the schematic diagram of the head circuit in earphone, because head circuit belongs to the state of the art, therefore is no longer developed in details herein, simply convenient understanding introduced below.In addition, Fig. 2 is illustrated that the composition of the head circuit of existing wired earphone, but it is only used for understanding operation principle, does not constitute any restriction.
As shown in Figure 2, SPK_L and SPK_R represent left and right miniature loudspeaker respectively, one of terminal L+ terminals of wherein left speaker are electrically connected to L terminals, one of terminal R+ terminals of right loudspeaker are electrically connected to R terminals, and another terminal of left speaker and right loudspeaker is all connected to G terminals (ground terminal).
Button includes three, include validating that button SW1 (also referred to as button Key_OK), volume-down keys SW2 (also referred to as button Key_V-), and volume increase button SW3 (also referred to as button Key_V+), it is respectively used to confirm, controls volume down
The increase of small and volume.It is understood that the quantity and control function of button are not limited, such as at least two buttons.
Three buttons are serial/parallel to be associated with three resistance R1, R2, R3, and each resistance is preset as certain resistance.Certain head circuit also includes miscellaneous part, such as electric capacity C1, Mike MIC etc., and the embodiment of the present invention is no longer introduced.
Understood with reference to Fig. 2, when user operates different buttons, the different stream of head circuit UNICOM, because resistance is different, causes to produce different electric signals at M+ terminals.For convenience, it is described so that electric signal is voltage as an example.
Terminal device can gather the voltage V of M+ terminals in head circuit, recognize it is which button according to default recognition threshold and rule.
At present, based on different mechanism, there are at least two identification methods.
First way, such as Fig. 3 a, recognition threshold are the mode of single numerical value.
Such as, terminal installation presets two threshold values, and each threshold value is single numerical value：Threshold value TH1, threshold value TH2；
As V≤TH1, then identify it is that button SW1 (Key_OK) is operated, then trigger correspondence and confirm function；
As V >=TH2, then identify it is that button SW2 (Key_V-) is operated, then trigger correspondence volume and reduce function；
Work as TH1<V<TH2, then identify it is that button SW3 (Key_V+) is operated, then trigger correspondence volume up function.
It is readily appreciated that, above-mentioned recognition rule can be arranged as required to.
But, if hardware aging, the resistance of such as button SW3 (Key_V+) series connection has played change, then it is possible that as Fig. 3 b, user operation button SW3 (Key_V+), has exceeded TH2 (shown in dotted line), then according to above-mentioned rule in the magnitude of voltage V+ of M+ terminals, even if user operation button SW3 (Key_V+), terminal installation can also be identified as button SW2 (Key_V-) and be operated.This is clearly inaccurate.
The second way, such as Fig. 4 a, recognition threshold are the mode of number range.
Such as, terminal installation presets three threshold values, and each threshold value is number range, including upper limit value and lower limit value：Threshold value TH1 (lower limit A1, higher limit A2), threshold value TH2 (lower limit B1, higher limit B2), threshold value TH3 (lower limit C1, higher limit C2),
As A1≤V≤A2, then identify it is that button SW1 (Key_OK) is operated, then trigger correspondence and confirm function；
As B1≤V≤B2, then identify it is that button SW3 (Key_V+) is operated, then trigger correspondence volume up function.
As C1≤V≤C2, then identify it is that button SW2 (Key_V-) is operated, then trigger correspondence volume and reduce function.
It is readily appreciated that, above-mentioned recognition rule can be arranged as required to.
If likewise, the resistance of hardware aging, such as button SW1 (Key_OK) series connection has played change, then be possible to such as Fig. 4 b so, user operation button SW1 (Key_OK), in the magnitude of voltage V of M+ terminalsokThreshold value TH1 higher limit A1 (shown in dotted line) is exceeded, even if then user operation button SW1 (Key_OK), terminal installation is None- identified.
The embodiment of the present invention is to solve the above problems.I.e. when the corresponding control function failure of at least one button of earphone
When, how the control function of key range.Described failure at least includes, and when user operates certain button, terminal installation cannot recognize that its corresponding control function.This corresponding control function can be pre-set by manufacturer or user oneself is set.
Terminal installation can provide a calibration function, and when at least one keys deactivation, user can start the calibration function.The embodiment of the present invention is not limited how to provide calibration function, can be that the ensuing operation of user is guided with the mode of voice, ensuing operation, or both can also be guided all to have with the mode of graphical interfaces, etc..Describe, introduced below in the way of graphical interfaces for convenience.
Understand for convenience, the embodiment of the present invention is introduced respectively according to two kinds of identification methods.
(1) the above-mentioned first way of correspondence：
When at least one button, such as when button SW3 (Key_V+) fails, user can start calibration function, open the graphical interfaces for correction.Certainly, terminal installation can also point out user to correct, such as periodically actively point out user.
Terminal installation can guide user according to control function by graphical interfaces, three buttons are operated successively, such as correspond to and confirm function, point out user operation button SW1 (Key_OK), correspondence volume increase function, point out user operation button SW3 (Key_V+), correspondence volume to reduce function, point out user operation SW2 (Key_V-).It is appreciated that the order of operation does not constitute restriction.
When the control unit of terminal installation obtains user's operation above three button, the electric signal of M+ terminals, such as voltage in head circuit, it is assumed that be respectively V1, V3, V2.
According to above-mentioned voltage V1, V3, V2, control unit is identified threshold value TH1 ', TH2 '.Control unit can set rule to obtain the identification thresholding.Such as a certain magnitude of voltage between V3 and V2 can be regard as the second recognition threshold TH2 ' for distinguishing button SW3 (Key_V+) and SW2 (Key_V-) using a certain magnitude of voltage between V1 and V3 as difference button SW1 (Key_OK) and SW3 (Key_V+) the first recognition threshold TH1 '.It is preferred that, V1 and V3 can be averaged as the first recognition threshold TH1 ', V3 and V2 are averaged and are used as the second recognition threshold TH2 '.
Based on the recognition threshold, terminal installation recognizes the control function of three buttons.After correction terminates, if user operates any button, head circuit can produce a magnitude of voltage V ', and control unit understands relations of the comparing voltage value V ' with above-mentioned recognition threshold, and recognizes the corresponding control function of the case according to default rule.Such as, if V '≤TH1 ', it is identified as button SW1 (Key_OK) and is operated, if V ' >=TH2 ', identifies it is that button SW2 (Key_V-) is operated, if TH1 '<V’<TH2 ', then identify it is that button SW3 (Key_V+) is operated.
It will be understood that number of keys can be at least two, the corresponding control function of button does not constitute restriction yet, but principle is similar.
So, even if earphone after used a period of time, hardware aging occurs, due to recognition threshold be based on hardware aging after button electric signal set so that terminal installation can recognize the button that user presses.
In addition, the resistance and/or operating voltage that its head circuit of the earphone of different producers is constituted may be different, when so different earphones is used cooperatively with same mobile terminal, if also using identical recognition threshold, user is also resulted in when operating button, terminal device can not be recognized or wrong identification.The embodiment of the present invention can also solve the problem, because terminal installation can be according to recognition threshold be reset per a earphone, so as to recognize the button of different earphones.
(2), the above-mentioned second way of correspondence, wherein the place similar with first way, will not be repeated here.
When at least one button, such as when button SW1 (Key_OK) fails, user can start calibration function, open the graphical interfaces for correction.Certainly, terminal installation can also point out user to correct, such as periodically actively point out user.
Terminal installation can guide user according to control function, three buttons are operated successively, such as correspond to and confirm function, point out user operation button SW1 (Key_OK), correspondence volume increase function, point out user operation button SW3 (Key_V+), correspondence volume to reduce function, point out user operation SW2 (Key_V-).It is appreciated that the order of operation does not constitute restriction.
When the control unit of terminal installation obtains user's operation above three button, the electric signal of M+ terminals, such as voltage in head circuit, it is assumed that be respectively V1, V3, V2.
According to above-mentioned voltage V1, V3, V2, control unit are identified threshold value.Control unit can obtain the recognition threshold with preset rules.Threshold value can be such as identified according to threshold factor, threshold factor is used as the upper and lower bound value for determining recognition threshold.For example the first threshold factor is a1, a2, then V1-a1 is set into A1 ', V1+a2 is set into A2 ', so as to obtain the lower and upper limit A1 ' and A2 ' of the first recognition threshold；The Second Threshold factor is b1, b2, then V3-b1 is set into B1 ', V1+b2 is set into B2 ', so as to obtain the lower and upper limit B1 ' and B2 ' of the second recognition threshold；3rd threshold factor is c1, c2, then V2-c1 is set into C1 ', V2+c2 is set into C2 ', so as to obtain the lower and upper limit C1 ' and C2 ' of the 3rd recognition threshold.Preferably, the size of threshold factor can be identical with identical or part.Such as a1, a2, b1, b2, c1, c2 value are identical, take Δ e；Can also, a1, a2 is Δ e1, and b1, b2 is Δ e2, and c1, c2 is Δ e3.
Based on the recognition threshold, terminal installation recognizes the control function of three buttons.After correction terminates, if user operates any button, head circuit can produce a magnitude of voltage V ', and control unit understands relations of the comparing voltage value V with above-mentioned recognition threshold, and recognizes the corresponding control function of the case according to default rule.Such as, work as A1 '≤V '≤A2 ', then identify it is that button SW1 (Key_OK) is operated, then trigger correspondence and confirm function；Work as B1 '≤V '≤B2 ', then identify it is that button SW3 (Key_V+) is operated, then trigger correspondence volume up function.Work as C1 '≤V '≤C2 ', then identify it is that button SW2 (Key_V-) is operated, then trigger correspondence volume and reduce function.
It will be understood that number of keys can be at least two, the corresponding control function of button does not constitute restriction yet, but principle is similar.
So, even if earphone after used a period of time, hardware aging occurs, due to recognition threshold be based on hardware aging after button electric signal set so that terminal installation can recognize the button that user presses.
In addition, resistance and/or operating voltage that its head circuit of the earphone of different producers is constituted may be different, so not
When same earphone is used cooperatively with same mobile terminal, if also using identical recognition threshold, user is also resulted in when operating button, terminal device can not be recognized or wrong identification.The embodiment of the present invention can also solve the problem, because terminal installation can be according to recognition threshold be reset per a earphone, so as to recognize the button of different earphones.
Further, for the above-mentioned second way of correspondence, the scheme of foregoing description is：If at least one keys deactivation, the magnitude of voltage that collection user operates each button and produced, so that it is determined that the recognition threshold after correction.It is preferable, however, that can be corrected just for the button of failure.When such as button SW1 (Key_OK) fails, terminal installation can only guide user to operate button SW1 (Key_OK), get voltage V1, and other buttons can not be corrected because not failing.Next, recognition threshold of the control unit according to the above-mentioned voltage V1 button SW1 (Key_OK) failed (specific method to set up, referring to above description, will not be repeated here).It so can also solve Similar Problems above.
One of ordinary skill in the art will appreciate that：Realizing all or part of step of above method embodiment can be completed by the related hardware of programmed instruction, and foregoing program can be stored in a computer read/write memory medium, and the program upon execution, performs the step of including above method embodiment；And foregoing storage medium includes：ROM, RAM, magnetic disc or CD etc. are various can be with the medium of store program codes.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although the present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It can still modify to the technical scheme described in foregoing embodiments, or carry out equivalent substitution to which part technical characteristic；And these modifications or replacement, the essence of appropriate technical solution is departed from the spirit and scope of various embodiments of the present invention technical scheme.
