Embodiments of the present application disclose a motor driving method, system, device and micro projection device. The motor driving method comprises: acquiring the number of beats of a motor and the pulse width of each beat, wherein the pulse width of each beat is the same; adjusting the pulse width of at least one beat to a target pulse width, and making the target pulse width greater than the pulse width; running the target pulse width of the beat to generate a driving pulse signal; and controlling the motor to run with the driving pulse signal. The scheme provided by the embodiments of the present application can keep the motor at a high working frequency and ensure the stability of the motor by changing the pulse width of the fixed number of beats of the motor.

The application discloses a kind of time music score, belong to music score technical field, solve the problem that the existing music score has no time information mark and leads to the difficulty of playing, playing music section selection positioning, rhythm control.The present application adds static or dynamic playing time information to each line, each measure or note of music score, and the time information is calculated according to the BPM and beat of music, and the playing time of single measure is (60 ÷ BPM) × each measure beat number, and the time precision is rounded to 0.1 second, and the time is marked in seconds (s) ;Multiple voices, lyrics are marked as a line;Time track, measure line marking, dynamic progress bar / mark multiple forms are used, and the measure number and time information of dynamic music score are one-to-one corresponding.The present application realizes the visualization of music score time dimension, accurately positions the music section, improves the efficiency of learning and playing, adapts to various music scores and digital playing tools, and has strong practicality.
