Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
First, a method for recognizing a fault contact according to an embodiment of the present invention will be described.
It should be noted that the method for identifying and processing a false touch ground provided by the embodiment of the present invention is applied to a mobile terminal. In particular, the mobile terminal may be any device having a communication function, such as: mobile phones, Tablet personal computers (Tablet personal Computer), Laptop computers (Laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), Wearable devices (Wearable Device), and the like.
Referring to fig. 1, a flowchart of a method for identifying a false touch ground according to an embodiment of the present invention is shown. As shown in fig. 1, the method is applied to a mobile terminal, a ground terminal of an earphone seat of the mobile terminal is grounded through a ground detection module, the ground detection module has at least two (for example, two, three, four, or more) working states, and resistances of the ground detection modules in the working states are different from each other, and the method includes the following steps:
Generally, as shown in fig. 2, the headset 1 includes a headset speaker 11, a headset jack 12, and a headset microphone and key module 13. The earphone speaker 11 is a device for playing sound; the earphone plug-in part 12 is used for being plugged with an earphone plug-in port of the earphone seat 2, and the microphone signal contact is specifically arranged on the earphone plug-in part 12; the earphone microphone and key module 13 is provided with a plurality of switches and a plurality of resistors, which enable combinations of different keys.
In a specific implementation manner of the embodiment of the present invention, detecting whether a grounding event occurs to a microphone signal contact disposed on an earphone includes:
acquiring the working voltage of a microphone signal contact arranged on the earphone;
and if the acquired working voltage is zero, determining that the grounding event occurs on the microphone signal contact.
It can be seen that, by such an embodiment, the mobile terminal can conveniently and quickly detect whether a grounding event occurs on the microphone signal contact.
It should be noted that when a grounding event occurs to the microphone signal contact, the grounding event may be caused by a user performing a key pressing operation on the earphone microphone and the key module 13 in fig. 2, or may be caused by a mis-contact of the microphone signal contact with the metal housing of the mobile terminal. If the mobile terminal directly responds to the grounding event, there is a possibility that an abnormal problem such as music stop or call hang-up may occur, and therefore, when the grounding event occurs in the microphone signal contact, the mobile terminal does not temporarily respond to the grounding event, but first performs step 102.
And 102, switching the working state of the grounding detection module.
It should be noted that, specific implementation forms of switching the working state of the ground fault detection module are various, and examples are described below.
In a specific implementation manner of the embodiment of the present invention, the ground fault detection module has two working states, and the ground fault detection module includes: the circuit comprises a resistor, a first switch and a second switch, wherein one end of the resistor is connected with a grounding end through the first switch, the other end of the resistor is grounded, and the grounding end is grounded through the second switch; before the mobile terminal detects a grounding event, the first switch is in an open state, and the second switch is in a closed state;
at this time, the switching of the working state of the grounding detection module includes:
and controlling the first switch to be closed and controlling the second switch to be opened so as to switch the working state of the grounding detection module.
In specific implementation, as shown in fig. 3 and 4 (fig. 4 is an equivalent circuit diagram of fig. 3), the ground fault detection module 3 includes: a resistor 31, a first switch 32, and a second switch 33; one end of the resistor 31 is connected to the ground terminal 21 of the earphone holder 2 through the first switch 32, the other end of the resistor 31 is grounded, and the ground terminal 21 of the earphone holder 2 is also grounded through the second switch 33. It can be seen that the ground detection module 3 has two operating states: when the first switch 32 is in a closed state and the second switch 33 is in an open state, the ground detection module 3 is in a working state, and the resistance of the ground detection module 3 is zero; when the first switch 32 is in an open state and the second switch 33 is in a closed state, the ground fault detection module 3 is in another working state, and the resistance of the ground fault detection module 3 is the resistance of the resistor 31.
It can be seen that in this embodiment, the structure of the ground detection module 3 is very simple, and the mobile terminal can conveniently and quickly switch the working state of the ground detection module 3.
And 103, acquiring working parameters of the microphone signal contact after the working state of the grounding detection module is switched.
The working parameters of the microphone signal contact may include a working voltage, and of course, the specific type of the working parameters is not limited thereto, and it is only required to ensure that the mobile terminal can determine whether the grounding event of the microphone signal contact is a false grounding event according to the working parameters.
In a specific implementation of the embodiment of the present invention, the operating parameter includes an operating voltage;
according to the obtained working parameters, judging whether the grounding event is a fault grounding event or not, comprising the following steps:
judging whether the obtained working voltage is zero or not;
if the working voltage is zero, determining that the grounding event is a false grounding event;
and if the working voltage is not zero, determining that the grounding event is not a false grounding event.
It can be seen that, by means of the embodiment, the mobile terminal can conveniently and quickly determine whether the grounding event of the microphone signal contact is a false grounding event.
In order to facilitate the understanding of the present solution for those skilled in the art, the following describes a detailed implementation process of the embodiment of the present invention with reference to fig. 3 and 4.
As shown in fig. 3 and 4, the earphone microphone and key module 13 has a microphone resistor R thereinmicIn addition, it is provided with a plurality of switches (S respectively)0、S1、S2、……、SnN may be 7) and a plurality of resistors (R respectively)1、R2、……、Rn，R1、R2、……、RnAre different from each other), R in fig. 40Is zero. S0、S1、S2、……、SnRespectively correspond to different keys, S0Corresponding may be send key, S1The corresponding key can be volume plus-minus key, the key corresponding to other switches can be determined according to the actual situation, and in the working process,S0、S1、……、Snat most one of them is in closed state, and the other switches are all in open state. It should be noted that V in FIG. 40Voltage, R, supplied to the earphone microphone for the power supply unitbIs a preset bias resistor for preventing V0Corresponding to the waveform distortion, Vin, is the voltage at the microphone input of the earphone (i.e., the operating voltage of the microphone signal contact, as described above).
It should be noted that in the case where no grounding event of the microphone signal contact is detected, the first switch 32 is in the open state and the second switch 33 is in the closed state.
Thus, when the earphone is inserted into the earphone jack of the earphone holder 2 and there is no key operation (at this time, S)0To SnAll remain in the off state), Vin may be calculated using the following equation (1):
when the earphone is plugged in the earphone jack of the earphone seat 2 and the key action exists (at this time, S)0To SnOne of them, e.g. SxIn a closed state under the action of the key, and the remaining switches remain in an open state), Vin may be calculated by using the following formula (2):
the calculation formula of Ru in the above formula (2) is shown in the following formula (3):
Ru＝∑Rx＝R0+……+Rx (3)
it should be noted that the grounding event of the microphone signal contact mainly occurs in the following two cases:
in the first case, the user presses S0Putting the switch in a closed state, keeping the other switches in an open state, obtaining zero Ru according to the formula (3), and substituting the zero Ru into the formula (2)To get Vin to be zero as well, and thus, the mobile terminal determines that a grounding event has occurred on the microphone signal contact. Since the grounding event in the first case is a pair S performed actively by the user0Is caused by a key press action, the grounding event is a normal grounding event.
In the second case, the microphone signal contact makes a false contact with the metal shell of the mobile terminal, and since the metal shell is connected to the ground of the main board, Vin is also zero at this time, so that the mobile terminal determines that the microphone signal contact has a ground event. Since the grounding event in the second case is caused by a mis-contact of the microphone signal contact with the metal housing, the grounding event is not a normal grounding event but a mis-contact grounding event.
Since the grounding event may occur in the above two cases, when the mobile terminal detects that Vin is zero, the mobile terminal does not temporarily respond to the grounding event, but first determines whether the grounding event is a false grounding event. In order to determine whether the grounding event is a false grounding event, the mobile terminal controls the first switch 32 to be closed and controls the second switch 33 to be opened.
If the grounding event is caused by the user's key pressing, Vin will change before and after the on/off states of the first switch 32 and the second switch 33 are switched, and the changed Vin can be calculated by the following formula (4):
it is easy to see that Vin calculated using equation (4) is not zero.
If the grounding event is caused by the erroneous contact between the microphone signal contact and the metal case, Vin will not change before and after the switching of the open/closed states of the first switch 32 and the second switch 33. Thus, Vin remains zero.
In view of this, after the switching of the open and closed states of the first switch 32 and the second switch 33, the mobile terminal acquires Vin again. If the obtained Vin is not zero, which means that Vin changes before and after the on-off states of the first switch 32 and the second switch 33 are switched, a grounding event is caused by a key operation of a user, and the mobile terminal responds to the grounding event. If the obtained Vin is zero, this indicates that Vin does not change before and after the on-off states of the first switch 32 and the second switch 33 are switched, so the grounding event is caused by the erroneous contact between the microphone signal contact and the metal shell, the grounding event is an erroneous contact grounding event, and the mobile terminal does not respond to the grounding event, so as to avoid abnormal problems such as music stop, call hang-up and the like.
In the embodiment of the invention, the mobile terminal is provided with the grounding detection module. When detecting that a grounding event occurs to a microphone signal contact arranged on the earphone, the mobile terminal does not temporarily respond to the grounding event, but switches the working state of the grounding detection module so as to change the resistance of the grounding detection module. After the resistance of the grounding detection module is changed, the mobile terminal can judge whether the grounding event is a mistaken grounding event according to the working parameters of the microphone signal contact. Under the condition that the grounding event is not the mistaken touch grounding event, the mobile terminal responds to the grounding event so as to respond to the key action of the user; and under the condition that the grounding event is the mistaken grounding event, the mobile terminal does not respond to the grounding event, so that the abnormal problems of music stop, call hang-up and the like are avoided. Therefore, by utilizing the grounding detection module, the embodiment of the invention solves the problem that the mobile terminal can respond to the mistaken grounding event of the microphone signal contact.
Optionally, after acquiring the operating parameters of the microphone signal contact, the method further includes:
the first switch is controlled to be opened, and the second switch is controlled to be closed.
As shown in fig. 3 and 4, after the mobile terminal controls the first switch 32 to be closed, controls the second switch 33 to be opened, and acquires Vin again, the mobile terminal may control the first switch 32 to be opened and control the second switch 33 to be closed. Thus, the resistance of the ground fault detection module 3 is restored to zero. Thereafter, when the mobile terminal detects Vin as zero again (i.e. the grounding event occurs again), the mobile terminal may control the first switch 32 to be closed again, control the second switch 33 to be opened, and acquire Vin again, so as to determine whether the grounding event occurring again is a false touch grounding event according to the acquired Vin again.
In summary, by using the grounding detection module, the embodiment of the invention better solves the problem that the mobile terminal can respond to the mistaken grounding event of the microphone signal contact.
The following describes a circuit for recognizing and processing a fault contact ground according to an embodiment of the present invention.
