As can be seen from fig. 3 to 5, ultrasonic sensor bars, each including at least one ultrasonic signal transmitter and ultrasonic signal receiver, are disposed at left and right sides of the mobile terminal. Alternatively, the width of the ultrasonic sensor strip may be 1mm, the height may be 0.15mm, and the length is the same as the length of the side of the mobile terminal. An FLEX circuit board and a plurality of piezoelectric ceramics are arranged on each ultrasonic sensor strip, and when voltage is applied to the piezoelectric ceramics, an ultrasonic signal transmitter or an ultrasonic signal receiver is formed.

When the state identifiers in the queue are all handheld state identifiers, the mobile terminal is determined to be in an uninterrupted handheld state in a time period between the receiving moment of the bright screen instruction and the moment of successfully unlocking the mobile terminal last time, the identity information of the current holding user can be determined, and the mobile terminal can be directly unlocked; when the state identifiers in the queue comprise one or more non-handheld state identifiers, it is determined that the non-handheld state time exists in a time period between the receiving time of the screen-up instruction and the time of the last successful unlocking of the mobile terminal, that is, the mobile terminal is in a discontinuous handheld state, the identity information of the current holding user cannot be determined, and the identity information of the current holding user needs to be verified.
After reading and judging the state identifier in the queue, the state identifier in the queue can be cleared or the queue can be deleted, so that a large amount of invalid data is prevented from occupying memory resources. And after the mobile terminal is successfully unlocked, re-acquiring the state identifier of the mobile terminal, wherein the successful unlocking of the mobile terminal comprises successful unlocking determined after reading and judging the state identifier in the queue, and also comprises successful unlocking determined after password verification by receiving a password input by a user.
