[0008] Furthermore, the sound collection module collects sound signals and inputs them into the control module.

[0009] Furthermore, the control module determines whether the sound signal satisfies a first preset condition, a second preset condition and a third preset condition.

[0010] Furthermore, if the control module determines that the sound signal satisfies the first preset condition, the second preset condition and the third preset condition, the control module controls the vibrator to vibrate.

[0011] Furthermore, the first preset condition is that the frequency of the sound signal is not less than 1500 Hz and not more than 3000 Hz.

If the control module 4 determines that the sound signal does not satisfy the first preset condition, the second preset condition and the third preset condition, the control module 4 does not control the vibrator 5 to vibrate. If the control module 4 determines that the sound signal satisfies the first preset condition, the second preset condition and the third preset condition, the control module 4 controls the vibrator 5 to vibrate. When the vibrator 5 vibrates, it can remind the driver, that is, it can realize real-time reminder of the driver to drive carefully according to the sound outside the vehicle.
