A pressure-sensitive vibration processing method can be applied to a mobile terminal including an application processor, a pressure sensor, and a vibration motor. The method can include: in a first state of the mobile terminal, notifying directly, with the pressure sensor, the vibration motor to generate vibration, when pressure received by the pressure sensor exceeds a threshold, the first state including a state where the application processor is in sleep; and in a second state of the mobile terminal, notifying, with the pressure sensor, the application processor to control the vibration motor to generate vibration, when pressure received by the pressure sensor exceeds the threshold, the second state including a state where the application processor is awake. A timely response is therefore ensured when vibration is needed, and it can also be ensured that various vibrations are handled normally during system operation to avoid abnormal vibration feedback.
