By when the protective case that electronic equipment is dressed is opened or is closed, or when being subject to external interference magnetic interference, Hall element on electronic equipment all can detect Hall voltage and change, the number therefore only being exported by Hall element According to determining whether to trigger bright screen event or screen event of going out, can lead to judge by accident.Therefore, the disclosure combines Hall element and distance passes Sensor is judged, can avoid judging by accident, and then avoid false triggering bright screen event or screen event of going out.

Wherein, interference magnetic field is except normal magnetic fluxs such as earth's magnetic field, the magnetic fields of electronic equipment dressed protective case upper magnet generation Magnetic field beyond, under the interference in interference magnetic field, the data according only to Hall element output cannot correctly judge whether to send out Protective case opening operation or shutoff operation are given birth to.Therefore, Hall voltage is being detected by the Hall element on electronic equipment During change, first judge whether electronic equipment local environment is interfered magnetic interference, determining that electronic equipment local environment is subject to During interference magnetic interference, the protective case dressed by range sensor detection electronic equipment is with respect to the screen of electronic equipment Distance.Protective case, with respect to the distance of the screen of electronic equipment, is the screen with respect to electronic equipment for the moving component of protective case Distance.May determine that by obtaining this distance the moving component of protective case is in the state away from screen, or close to screen The state of curtain, determines whether to trigger bright screen event or screen event of going out.Specifically, protect if determined according to institute's detecting distance The moving component of sheath is in the state away from screen, then trigger bright screen event, if determining protective case according to institute's detecting distance Moving component be in state close to screen, then triggering is gone out screen event.

In an optional implementation, when determination electronic equipment local environment is not interfered magnetic interference, Can judge whether to trigger bright screen event or screen event of going out by the output result of described Hall element.

It can be seen that, the present embodiment, can be using suddenly when determination electronic equipment local environment is not interfered magnetic interference The output result of your sensor judges whether to trigger bright screen event or screen event of going out, and easily realizes, and can avoid any Situation only carries out the erroneous judgement judging to lead to range sensor.

In another optional implementation, determining that electronic equipment local environment is not interfered magnetic interference When, judge whether to trigger bright screen event or screen thing of going out by the output result and institute's detecting distance of described Hall element simultaneously Part.

This embodiment can pass through the output result of Hall element and institute's detecting distance judges whether to trigger bright screen simultaneously Event or screen event of going out, just trigger this event when judging triggering similar events according to output result and institute's detecting distance, otherwise Do not process.

It can be seen that, the present embodiment, can be by suddenly when determination electronic equipment local environment is not interfered magnetic interference The output result of your sensor and institute's detecting distance judge whether to trigger bright screen event or screen event of going out simultaneously, thus realizing improving The accuracy rate judging, and improve Consumer's Experience, it is to avoid judge the worry brought to user by accident.

As seen from the above-described embodiment, the disclosure is detecting Hall voltage change by the Hall element on electronic equipment When, judge whether electronic equipment local environment is interfered magnetic interference, determining that electronic equipment local environment is interfered magnetic During interference, the distance that the protective case dressed of electronic equipment is with respect to the screen of electronic equipment is detected by range sensor, Judge whether to trigger bright screen event or screen event of going out according to institute's detecting distance.By Hall element is carried out with range sensor In conjunction with such that it is able to avoid when being interfered magnetic interference only carrying out judging leading to by the output result of Hall element Erroneous judgement, and then avoid erroneous judgement to bring bad Consumer's Experience to user.

Judge that whether the be interfered mode of magnetic interference of electronic equipment local environment has many kinds, be exemplified below wherein several The mode of kind illustrates.

In an optional implementation, when receiving interference instruction, judge whether electronic equipment local environment is subject to To interference magnetic interference.Interference instruction can be the instruction that user triggers generation by way of triggering keys or buttons, and this is done Disturb instruction and represent that current environment is interfered magnetic interference.

It can be seen that, realize disturbing the judgement in magnetic field by way of interference instructs, easily realize.

In another optional implementation, the magnetic that the magnetic field sensor according to being arranged on described protective case is detected Field intensity judges whether electronic equipment local environment is interfered magnetic interference, wherein, in described protective case closure or opened Cheng Zhong, the relative position of described magnetic field sensor and described protective case upper magnet is fixed.

In this embodiment it is possible to magnetic field sensor is arranged on the protective sleeve, and magnetic field sensor and magnetic on protective case The relative position of ferrum is fixed, so that the shadow of the detected magnetic field intensity of magnetic field sensor unprotected set closing course and opening process Ring, the magnetic field intensity that is, magnetic field sensor detects in protective case closing course with opening process is identical or differs not at one In the range of big magnetic field intensity.

In one example, the magnetic field that can be detected according to magnetic field sensor in protective case closing course and opening process Intensity arranges a magnetic field intensity threshold range.If the magnetic field intensity that magnetic field sensor detects is in magnetic field intensity threshold range Interior, then judge that electronic equipment local environment is not interfered magnetic interference；If the magnetic field intensity that magnetic field sensor detects Not in magnetic field intensity threshold range, then judge that electronic equipment local environment is interfered magnetic interference.

Further, since magnetic field sensor arranges on the protective sleeve, for magnetic field sensing that can be from setting on the protective sleeve Magnetic field intensity is obtained, electronic equipment can be connected with magnetic field sensor by way of wired or wireless, to get in device The magnetic field intensity that magnetic field sensor detects.

It can be seen that, in this embodiment it is possible to obtain magnetic field intensity from setting magnetic field sensor on the protective sleeve, pass through Acquired magnetic field intensity judges whether electronic equipment local environment is interfered magnetic interference, thus realize automatic decision being currently The no magnetic interference that is interfered, need not manually participate in.

In another optional implementation, magnetic field can be obtained from setting magnetic field sensor on an electronic device Intensity level and/or magnetization direction, judge electronic equipment institute according to acquired field strength values and/or magnetization direction Whether place's environment is interfered magnetic interference.As shown in Fig. 2 Fig. 2 to be the disclosure another according to an exemplary embodiment The flow chart planting screen control method, the method can be used in electronic equipment, and the method comprises the following steps 201 to step 204:

In step 201, when Hall voltage change is detected by the Hall element on electronic equipment, from being arranged on Field strength values and/or magnetization direction is obtained in magnetic field sensor on electronic equipment.

In step 202., judge ring residing for electronic equipment according to acquired field strength values and/or magnetization direction Whether border is interfered magnetic interference.

In step 203, when the described electronic equipment local environment of determination is interfered magnetic interference, by Distance-sensing The protective case that the device described electronic equipment of detection is dressed is with respect to the distance of the screen of electronic equipment.

In step 204, judge whether to trigger bright screen event or screen event of going out, described bright screen event according to institute's detecting distance It is the event that electronic equipment screen is lighted, described screen event of going out is by the event of electronic equipment screen breath screen.

In this embodiment, because magnetic field sensor arranges on an electronic device, therefore, the magnetic that magnetic field sensor is detected Field intensity can be protected covering the impact of opening procedure and closing course.Detected by the Hall element on electronic equipment During Hall voltage change, field strength values and/or the magnetic that setting magnetic field sensor on an electronic device detects can be obtained Field intensity direction.

For magnetization direction, protective case opening procedure can be gathered and closes in the case of there is not interference magnetic field Magnetization direction during conjunction, obtains a default magnetization direction.If Hall element detects Hall voltage During changing, when acquired magnetization direction is different from default magnetization direction, judge electronic equipment institute Place's environment is interfered magnetic interference, and described default magnetization direction is described magnetic field sensor under the influence of interference-free magnetic field The magnetic direction detecting.Magnetic field sensor can detect three-axle magnetic field direction, if the three-axle magnetic field direction detected is wherein One axle is different from default magnetization direction, then can be determined that electronic equipment local environment is interfered magnetic interference.

It can be seen that, judge whether electronic equipment local environment is interfered magnetic interference by magnetization direction, easily real Existing.

For field strength values, when acquired field strength values are more than default magnetic field intensity threshold value, judge electronic equipment Local environment is interfered magnetic interference.

In this embodiment it is possible to pre-set a magnetic field intensity threshold value, described default magnetic field intensity threshold value is more than not It is disturbed the field strength values that magnetic field sensor under the influence of magnetic field detects.Therefore, it is more than in advance in acquired field strength values If during magnetic field intensity threshold value it is possible to determine that electronic equipment local environment is interfered magnetic interference.

In one example, described default magnetic field intensity threshold value determines according to maximum magnetic field strength value, described maximum field Intensity level is that the magnetic field that described magnetic field sensor detects in described protective case closure state under the influence of interference-free magnetic field is strong Angle value.

In the impact of interference-free magnetic field and in the case of protective case closure, the magnetic field intensity that magnetic field sensor detects is Greatly, this intensity level can be defined as maximum magnetic field strength value.

On the one hand, default magnetic field intensity threshold value can be identical with maximum magnetic field strength value.Now, acquired magnetic field intensity When value is more than maximum magnetic field strength value, then judge that electronic equipment local environment is interfered magnetic interference.

On the other hand, the impact leading in order to avoid detection error, default magnetic field intensity threshold value can be to compare maximum field The slightly larger or smaller value of intensity level.Because default magnetic field intensity threshold value is more slightly larger or smaller than maximum magnetic field strength value, therefore permissible Avoid the erroneous judgement leading to due to detection error.

In another example, although the magnetic interference that is interfered in some cases, but if interference magnetic field is not big, Be not enough to affect the output result of Hall element, then still can adopt the output result of Hall element judge whether to trigger bright Screen event, based on this, described default magnetic field intensity threshold value determines according to critical magnetic field strength, and described critical magnetic field strength is The magnetic field that when Hall element triggers bright screen event/screen event of going out under the influence of interference-free magnetic field, described magnetic field sensor detects Intensity level.

Due to Hall element detect the bright screen event that can trigger that just can export when Hall voltage changes to marginal value/ The output result of screen event of going out, therefore when Hall voltage reaches marginal value, obtains the magnetic field intensity that magnetic field sensor detects Marginal value.For example, Hall element can represent that triggering is bright output 1,1 is detected when Hall voltage changes to the first marginal value Screen event, obtains Hall voltage and changes to the first critical magnetic field strength that magnetic field sensor during the first marginal value detects；Suddenly Your sensor can represent that triggering is gone out screen event, obtains suddenly output 0,0 when Hall voltage changes to the second marginal value is detected The second critical magnetic field strength that your potential change detects to magnetic field sensor during the second marginal value.Wherein, the first marginal value With the second marginal value can identical it is also possible to differ, with specific reference to demand set.

In an optional implementation, described default magnetic field intensity threshold value is according to maximum magnetic field strength value and the first magnetic The value preset of field intensity marginal value determines, described maximum magnetic field strength value is that described magnetic field sensor exists under the influence of interference-free magnetic field The field strength values detecting during described protective case closure state, described first critical magnetic field strength is interference-free magnetic field shadow Ring the field strength values that when lower Hall element triggers bright screen event, described magnetic field sensor detects.

As one of which abnormal conditions, open protective case and but do not light screen, should be it may be the case that because cannot make Hall voltage reaches the first marginal value, then there may be one identical with the first critical magnetic field strength direction and more than or wait Magnetic field intensity in the first critical magnetic field strength.Therefore, default magnetic field intensity threshold value can be the value more than or equal to value preset, Can also be the value more slightly smaller than value preset.Described value preset is the value preset of maximum magnetic field strength value and the first critical magnetic field strength, institute Stating maximum magnetic field strength value is that described magnetic field sensor detects in described protective case closure state under the influence of interference-free magnetic field The field strength values arriving, described first critical magnetic field strength is Hall element triggering bright screen thing under the influence of interference-free magnetic field The field strength values that during part, described magnetic field sensor detects.

Based on this, magnetic field sensor prison in opening procedure can be obtained from setting magnetic field sensor on an electronic device The maximum measuring, when acquired maximum is more than default magnetic field intensity threshold value, judges that electronic equipment local environment is subject to Interference magnetic interference.This embodiment can avoid opening the abnormal conditions that protective case does not but light screen.

In another optional implementation, described default magnetic field intensity threshold value is true according to the second critical magnetic field strength Fixed, described default magnetization direction is in opposite direction with the second critical magnetic field strength, described second critical magnetic field strength Be under the influence of interference-free magnetic field Hall element triggering go out screen event when the field strength values that detect of described magnetic field sensor.

As one of which abnormal conditions, close protective case and but do not cease screen, should be it may be the case that because Hall cannot be made Potential reaches the second marginal value, then there may be one in opposite direction with the second critical magnetic field strength and more than or equal to the The magnetic field intensity of two critical magnetic field strength.Therefore, default magnetic field intensity threshold value can be more than or equal to the second magnetic field intensity The value of marginal value, or be the value more slightly smaller than the second critical magnetic field strength.

Based on this, from setting magnetic field sensor on an electronic device, obtain field strength values and magnetization direction, When acquired magnetic field intensity is more than or equal to default magnetic field intensity threshold value, acquired magnetization direction is strong with the second magnetic field Degree marginal value in opposite direction when, judge that electronic equipment local environment is interfered magnetic interference.This embodiment can avoid closing Close the abnormal conditions that protective case does not but extinguish screen, and then avoid the electricity that bright screen leads to waste.

It can be seen that, can individually judge whether electronic equipment local environment is subject to according to field strength values or magnetization direction Interference magnetic interference is it is also possible to be combined whether judging electronic equipment local environment by field strength values and magnetization direction Be interfered magnetic interference.

In addition, step 203 is identical with 103 correlation techniques with step 102 with 204, this is no longer going to repeat them.

As seen from the above-described embodiment, the present embodiment is detecting Hall voltage change by the Hall element on electronic equipment During change, from setting magnetic field sensor on an electronic device, obtain field strength values and/or magnetization direction, according to being obtained The field strength values taking and/or magnetization direction judge whether electronic equipment local environment is interfered magnetic interference, true Determine electronic equipment local environment be interfered magnetic interference when, the protective case dressed of electronic equipment is detected by range sensor With respect to the distance of the screen of electronic equipment, judge whether to trigger bright screen event or screen event of going out according to institute's detecting distance.This reality Apply the field strength values that example detected by magnetic field sensor and/or magnetization direction judges whether electronic equipment local environment is subject to To interference magnetic interference, thus realizing automatic decision, need not manually participate in, cost-effective, it is to avoid what artificial judgment led to fails to judge.

It is understood that above-mentioned only listing wherein several judges whether electronic equipment local environment is interfered magnetic field The method of interference, can also include other modes, this is no longer going to repeat them.
