The mobile terminal can be provided with a gravity sensor, the acceleration value of the mobile terminal is detected through the gravity sensor, if the acceleration value is larger than or equal to a preset threshold value, the mobile terminal is determined to be in a preset motion state, wherein the preset threshold value can be a user-defined numerical value or a default numerical value. If the acceleration value is equal to 9.8m/s2Then it is determined that the mobile terminal is in a free-fall motion state.
For example, if the predetermined threshold is 5m/s2The value of the gravitational acceleration detected by the gravitational sensor is 8m/s2And determining that the mobile terminal is in a falling state with the acceleration value larger than a preset threshold value. If the gravity acceleration detected by the gravity sensor is 9.8m/s2Then it is determined that the mobile terminal is in a free-fall motion state.
In step 301, if the mobile terminal is in a preset motion state, it is indicated that the mobile terminal falls from a high place to a low place, and in the falling process, step 302 is executed. If the mobile terminal is not in the preset motion state, it indicates that the mobile terminal is not in the falling process, and if the mobile terminal is in the static state, the process is ended.
Step 302, respectively detecting a first sound pressure and a second sound pressure by a first microphone and a second microphone.

In the embodiment of the invention, the mobile terminal pushes the ambient air in the falling process, so that the air pressure of the ambient environment is changed, and the microphone of the mobile terminal generates corresponding sound pressure due to the change of the air pressure. The larger the air pressure received by the microphone, the larger the corresponding generated sound pressure, and the smaller the air pressure received by the microphone, the smaller the corresponding generated sound pressure.
For example, when the mobile terminal 40 is dropped face down, the first microphone 401 detects a first sound pressure that is greater than the second sound pressure detected by the second microphone 402. When the mobile terminal 40 is dropped face down, the first sound pressure detected by the first microphone 401 is smaller than the second sound pressure detected by the second microphone 402.
And step 303, determining whether the screen of the mobile terminal falls downwards according to the first sound pressure and the second sound pressure.
In the embodiment of the invention, if the first sound pressure is greater than the second sound pressure, it is determined that the screen of the mobile terminal falls downwards. In order to avoid damaging the screen of the mobile terminal in the falling process, the mobile terminal needs to be rotated so that the screen of the mobile terminal faces upwards.
And if the first sound pressure is smaller than the second sound pressure, determining that the screen of the mobile terminal falls upwards. In the falling process of the mobile terminal with the screen facing upwards, the screen cannot be damaged.
And 304, if the screen of the mobile terminal falls downwards, controlling the mobile terminal to turn over so that the screen of the mobile terminal faces upwards.
In the embodiment of the invention, the motor can be arranged on the mobile terminal, the preset motor parameters are obtained when the screen of the mobile terminal falls downwards, the motor parameters comprise parameters such as motor vibration direction and vibration frequency, and the motor is controlled to vibrate according to the motor parameters, so that the mobile terminal is turned over, and the screen of the mobile terminal faces upwards.
In the embodiment of the invention, if the screen of the mobile terminal falls downwards, the mobile terminal can also broadcast the reminding message through voice, wherein the reminding message is used for reminding a user that the current mobile terminal is in a falling state with the screen downwards, and the motion state of the mobile terminal can be prompted to the user in real time through voice, so that the user can be ensured to process the falling motion state of the mobile terminal in time, and the damage of the mobile terminal is avoided.
In the embodiment of the invention, whether the mobile terminal is in a preset motion state is judged; if the mobile terminal is in a preset motion state, respectively detecting first sound pressure and second sound pressure through the first microphone and the second microphone; determining whether a screen of the mobile terminal falls downwards or not according to the first sound pressure and the second sound pressure; and if the screen of the mobile terminal falls downwards, controlling the mobile terminal to turn over so that the screen of the mobile terminal faces upwards. Like this, at mobile terminal's the in-process that falls, can overturn mobile terminal for mobile terminal's screen is up, reduces the risk of garrulous screen, improves mobile terminal's security performance.
Referring to fig. 6, fig. 6 is a schematic flow chart of another fall processing method of a mobile terminal according to an embodiment of the present invention, where the fall processing method is applied to the mobile terminal, a screen is disposed on a front surface of the mobile terminal, a first microphone is further disposed on the front surface of the mobile terminal, and a second microphone is disposed on a back surface of the mobile terminal, as shown in fig. 6, the method includes:
step 601, judging whether the mobile terminal is in a preset motion state.
In the embodiment of the present invention, the preset motion state may include a free-fall motion state and a fall state in which an acceleration value is greater than a preset threshold value. The mobile terminal can be provided with a gravity sensor, the acceleration value of the mobile terminal is detected through the gravity sensor, if the acceleration value is larger than or equal to a preset threshold value, the mobile terminal is determined to be in a preset motion state, wherein the preset threshold value can be a user-defined numerical value or a default numerical value. If the acceleration value is equal to 9.8m/s2Then it is determined that the mobile terminal is in a free-fall motion state.
For example, if the predetermined threshold is 6m/s2The value of the gravitational acceleration detected by the gravitational sensor is 7m/s2And determining that the mobile terminal is in a falling state with the acceleration value larger than a preset threshold value. If the gravity acceleration detected by the gravity sensor is 9.8m/s2Then it is determined that the mobile terminal is in a free-fall motion state.
In step 601, if the mobile terminal is in a preset motion state, it is indicated that the mobile terminal falls from a high place to a low place, and in the falling process, step 602 is executed. If the mobile terminal is not in the preset motion state, it indicates that the mobile terminal is not in the falling process, and if the mobile terminal is in the static state, the process is ended.
