The timer 30 starts timing according to the electrical signal transmitted by the sound collection module 20 or starts counting after a preset time period; the timer starts from zero, and the preset duration is Δt. After each timing Δt, the timer sends a timing pulse and clears the timer. Zero restarts timing, Δt takes a very small value, preferably 20 ms. In addition to the trigger timing of the preset duration, the timer can also be timed from zero by other trigger events. When the external feedback signal is triggered, it will be cleared and restarted, and a feedback pulse will be sent.

The control module 50 controls the ball of the unlocking interface 10 to roll forward with the rolling speed V calculated by the calculation module 40 (specifically the first calculating unit 401) in the fixed length channel; FIG. 2(b) shows a small The state in which the ball rolls within a fixed length channel.

The unlocking module 60 receives the rolling distance of the ball outputted by the calculating module 40 in the fixed length channel and compares with the length of the preset fixed length channel, if the small ball rolling distance is greater than or equal to the preset fixed length channel The length is controlled to unlock. Specifically, the unlocking module 60 receives the accumulated result S′ output by the accumulating unit 403 and compares it with the preset fixed length channel L. If S′≥L is satisfied, the ball is considered to have rolled into the destination, and the ball stops scrolling. The control unlock is completed; otherwise, the feedback signal is sent to the timer 30, and the ball continues to scroll. Figure 2(c) shows the state in which the ball rolls into the fixed length channel terminal destination.

The distance is such that the rolling distance of the ball within the fixed length channel is obtained.

S500. The unlocking module receives a rolling distance of a ball output by the calculating module in a fixed length channel and compares with a length of a preset fixed length channel, if the small ball rolling distance is greater than or equal to a preset fixed length channel. The length is controlled to unlock, otherwise the feedback signal is restarted to the timer, and the calculation module continues to calculate the speed at which the ball rolls forward and its rolling distance within the fixed length channel.

Preferably, the method of the present invention further includes a storage module configured to store a distance that the small balls output by the accumulation unit continuously scroll.

The implementation process of the mobile phone unlocking method of the present invention is specifically described below with reference to FIG. 1 and FIG. 2 and the working principle of the mobile phone unlocking system. The specific parameters follow the specific application example of the mobile phone unlocking system.

When the mobile phone is in the lock screen state, the user enters the unlock interface 10 by lighting the screen.

The user starts to blow the microphone of the mobile phone, and the sound pickup module 20 senses the input of the airflow A1, and outputs the converted electrical signal U1 to the first calculating unit 401, while the triggering timer 30 initializes the counting from zero.

The first calculating unit 401 starts the calculation of the first rolling speed V1 of the small ball according to the preset formula V=KU and outputs it to the control module 50, and the control module 50 controls the small ball to start rolling at the speed V1. (V1=KU1).

The timer 30 counts from zero to ∆t, sends a timing pulse to the second calculation unit 402, and the second calculation unit 402 starts the calculation of the first rolling distance S1 of the small ball according to the preset formula S=VT, and outputs S1 to Accumulating unit 403, where S1 = V1 ∆ t.

The accumulating unit 403 starts the first cumulative scrolling distance S1' calculation, and outputs S1' to the storage module 70 and the unlocking module 60. Where S1'=S1+S0, S0 is the rolling distance before the first rolling of the ball, so S0=0, S1'=S1.

The unlocking module 60 compares S1' with the preset fixed channel length L. If S' ≥ L is satisfied, the control is successfully unlocked; otherwise, the feedback signal is output to the timer 30 to start a new time.

After receiving the feedback signal, the timer 30 sends a feedback pulse to the first calculating unit 401 and clears the restart timing;

The first calculating unit 401 reads the current electrical signal U2 under the action of the feedback pulse, and starts the calculation of the second rolling speed V2 of the small ball according to the formula and outputs it to the control module 50, and the control module 50 controls the small ball to make the V2. Secondary scrolling, V2 = KU2.

The timer 30 sends a timing pulse to the second calculating unit 402 from zero to ∆t, and calculates a second rolling distance S2 and a second cumulative rolling distance S2'. If S2'≥L is satisfied, the control is successfully unlocked; Conversely, the feedback signal is sent again to the timer 30;

After receiving the feedback signal, the timer 30 sends a feedback pulse to the first calculating unit 401 and clears the re-clocking again. The first unit 401 calculates the third rolling speed V3; the control module 50 controls the ball to scroll at V3.

Similarly, after counting ∆t, the third rolling distance S3 and the third cumulative rolling distance S3' are calculated. If S3' ≥ L is satisfied, the control is successfully unlocked; otherwise, the next timing and scrolling is started.

By the way, after the timer 30 counts to ∆t, the second calculating unit 402 calculates the current scrolling distance S and the current accumulated scrolling distance S′ according to the current speed V, and the unlocking module performs the unlocking determination, and performs the unlocking according to the determination result. Operate or continue to scroll next time.

When the timer 30 is timed to ∆t, the second calculating unit 402 calculates the xth rolling distance Sx, Sx=Vx∆t according to the current speed Vx.

The accumulating unit 403 calculates the xth cumulative rolling distance Sx',

Sx'= S(x-1)'+ Sx = S0+S1+S2+...+S(x-1)+ Sx + S(x+1),

The unlocking module 60 compares Sx' with the preset fixed channel length L, Sx' satisfies Sx' ≥ L, and the ball stops scrolling, and the unlocking is successful.
