Preferred embodiment of the invention

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

Embodiment 1

The mobile terminal anti-theft method of this embodiment is applied to a mobile terminal, such as a mobile phone, a tablet computer, an iPad, a PDA, etc., on which a pressure sensing module is mounted on the outer casing. As shown in Figure 1, the method includes:

Step 110: Open an anti-theft mode according to a user instruction.

The anti-theft method of the present embodiment is used in a specific anti-theft mode. For example, when a user places a mobile terminal in a pocket or a bag in a crowded place such as a bus or a subway, the anti-theft mode can be turned on. Alternatively, when the user needs to place the mobile terminal somewhere in a public place, the anti-theft mode can also be turned on. The anti-theft mode should be as simple as possible, such as by pressing and holding the power button for a few seconds, in the pop-up dish Select one button to enter the anti-theft mode. When the user returns to the home or safe area, the user can turn off the anti-theft mode, so that the alarm will not be frequently caused, which affects normal use.

Step 120: Monitor the detected value of the pressure sensing module in real time;

In this embodiment, the pressure sensing module is a capacitive pressure sensing module, including a moving plate mounted on the inner side of the rear casing of the mobile terminal, and a fixed pole mounted on the mobile terminal main board or inside the front shell. Board, and detection circuit. The movable plate and the fixed plate form a parallel plate capacitor connected to the detecting circuit; the detecting circuit changes a distance between the moving plate and the fixed plate (the capacitance value changes) The output voltage then changes. That is, the detected value of the pressure sensing module is the output voltage of the detecting circuit.

However, the pressure sensor of the embodiment of the present invention is not limited to the above specific form. The pressure sensing module is now mature in technology, and other existing pressure sensors can be used as long as the small deformation of the mobile terminal casing can be sensed. can.

Step 130, according to the change of the detection value of the pressure sensing module, determine whether the preset alarm condition is met, if yes, perform step 140, otherwise, perform step 120;

In this embodiment, the preset alarm condition includes a first condition, and the first condition is:

The detection value of the pressure sensing module is monitored to change; or the detected value of the pressure sensing module is detected to change and the amount of change exceeds the set first threshold.

The former does not need to perform threshold judgment. As long as the detection value of the pressure sensing module changes, the first condition is satisfied, and the pressure change is more sensitive when used, but it is easy to cause frequent alarms due to some non-theft behavior. The latter requires threshold judgment, and the first condition is satisfied when the pressure changes to a certain extent, and the sensitivity is related to the threshold size. The above threshold may be configured by the mobile terminal manufacturer, may be configured by the user, or selected by the user according to multiple values configured by the manufacturer, and the like.

In step 140, an alarm is issued.

In general, an alarm can be made by means of sound and/or vibration. When an audible alarm is given, the current volume setting is ignored and the alarm tone is played at the maximum volume.

In particular, the alarm of the embodiment includes: playing an alarm ringtone set by the user to perform an alarm. In this way, the user can perceive that the ringtone is in the alarm, and for others, just feel that a ringtone is played, which can avoid false alarms and cause interference to others.

The anti-theft mode can be manually turned off by the user or automatically turned off after the user uses the function of the mobile terminal.

It should be noted that, in the embodiment of the present invention, it is required to determine whether the preset alarm condition is met according to the change of the detected value of the pressure sensing module, but the other conditions other than the detected value are not excluded as an alarm. condition.

In another embodiment, based on the first embodiment, the method further includes:

In the anti-theft mode, the mobile terminal enters a password lock state. That is, the user does not turn on the screen lock function, and in the anti-theft mode, the screen lock is also required. And after locking, the user must enter a password such as a string of symbols or a specific pattern to unlock. In the anti-theft mode, when the mobile terminal enters the password lock state, if the mobile terminal currently has the password lock enabled, the current password lock mode can be used to lock the screen. If the mobile terminal does not currently enable the password lock, the password is still locked in the password lock mode. The password when unlocking may be the unlock password set by the user for the anti-theft mode, or the unlock password used by the user in the normal mode.

Correspondingly, in step 130, according to the change of the detected value of the pressure sensing module, determining whether the preset alarm condition is met, in addition to determining whether the first condition is satisfied, determining whether the following second condition is satisfied, that is, The preset alarm conditions also include the following second condition:

The mobile terminal is still in a locked state within a first set duration after the first condition is satisfied.

The second condition is mainly used to distinguish whether the user or the other person is holding the mobile terminal. If it is the person, the unnecessary alarm can be avoided by the timely unlocking operation, and the thief does not know the unlocking password, so the mobile terminal will alarm . The setting of this condition can reduce frequent alarms and cause unnecessary interference and inconvenience to the user.

The first set duration may be configured by the mobile terminal manufacturer, may be configured by the user, or selected by the user according to multiple values configured by the manufacturer, and the like. In one example, the duration may be set to a time value greater than or equal to 10 seconds or less than or equal to 1 minute, such as 25, 30 seconds, 40 seconds, and the like. For specific values, the embodiment of the present invention does not impose any limitation.

The mobile terminal is further provided with a light sensing module, such as a light sensing chip. Many smartphones are currently It has a light-sensitive chip and does not need to be added separately.

Correspondingly, in step 130, according to the change of the detected value of the pressure sensing module, determining whether the preset alarm condition is met, in addition to determining whether the first condition is satisfied, determining whether the following third condition is satisfied, that is, The preset alarm conditions also include the following third conditions:

By adding the above third condition, some false alarms can be avoided. For example, after the mobile terminal is placed in the bag and the pocket, the collision detection between the items may cause the detection value of the pressure sensing module to change, and the user will not unlock at this time. Operation, which will cause false alarms. The detection values (such as light lumens) of the light sensing module of the mobile terminal placed in the bag and in the pocket generally do not change or change very little. After the third condition is added, no false alarm will occur. If it is stolen, the mobile terminal will be taken out of the bag and pocket, and there will be light changes, so that the alarm can still be normally performed. In addition, even if it is placed in a scene with light, the detection value of the light sensing module will change when the mobile terminal is moved, and the alarm can be normally performed at this time.

In still another embodiment, based on the first embodiment, the contents of the second embodiment and the third embodiment are combined, namely:

After the anti-theft mode is turned on according to the user's instruction, the mobile terminal enters the password lock state. When it is determined whether the preset alarm condition is met according to the change of the detected value of the pressure sensing module, it is necessary to simultaneously satisfy the first condition, the second condition, and the third condition to perform an alarm.
