Claim 11:
12. The driving mechanism as claimed in claim 11, wherein:
during the first control mode, the control signal does not include a periodic signal with a frequency higher than the maximum frequency;
during the first control mode, the first driving signal does not include a periodic signal with a frequency higher than the maximum frequency;
during the first control mode, an absolute value of the voltage or the current of the first driving signal increased by the control assembly is different than an absolute value of the voltage or the current of the third driving signal increased by the control assembly;
during the second control mode, the control signal does not include a periodic signal with a frequency higher than the maximum frequency;
during the second control mode, the first driving signal does not include a periodic signal with a frequency higher than the maximum frequency.
