Embodiment Construction
[0019] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, a flow chart of a motor control method in a mobile terminal provided by an embodiment of the present invention, the method includes:
[0021] Step 101: Detect the signal characteristics of the input audio signal;
[0022] Step 102: Determine the driving signal corresponding to the signal feature of the audio signal according to the mapping relationship between the signal feature and the driving signal;
[0023] Step 103: Drive the motor to work according to the driving signal.
[0024] The audio signal detected in the embodiment of the present invention can be a digital signal or an analog signal. The audio signal is a digital signal as an example for description below. The processing method when the audio signal is an analog signal is the same as when the audio signal is a digital signal. The processing method is t...

The invention relates to the technical field of automatic control, and the embodiment of the invention provides a motor control method and device in a mobile terminal. The method includes detecting a signal feature of an input audio signal; according to a mapping relation between the signal feature and driving signals, determining a driving signal corresponding to the signal feature of the audio signal; and driving a motor to work according to the driving signal. According to the method provided by the embodiment of the invention, the driving signal corresponding to the signal feature is determined by detecting the signal feature of the input audio signal, and the motor is driven to work. Since the signal feature of the audio signal constantly changes, different driving signals can be generated to drive the motor to work; voice prompts with different volumes and different frequencies for different events can be converted into vibration prompts; or even, vibration of the motor changes along with the change of the voice in real time, and thus the user experience is enriched.
Description
technical field [0001] The present invention relates to the technical field of automatic control, in particular to a motor control method and device in a mobile terminal. Background technique [0002] As a symbol of scientific and technological progress in modern society, mobile phones have become almost a must-have tool for everyone. Mobile phones have played a very important role in our lives with their unique convenience, quickness and versatility. Text messages and phone calls have become one of the most common and commonly used communication methods among people. When we receive a text message or receive a call, the ringtone of the mobile phone can remember to remind us at the first time. But in some occasions, ringing one after another is unacceptable. At this time, the vibration function of the mobile phone can remind oneself in time without affecting others, and at the same time solve the inconvenience caused by the ringtone of the mobile phone. [0003] The vibr...
