The invention relates to a drive unit (1) for generating an oscillatory motion for an electrical small-scale unit.
本发明涉及一种驱动单元(1)，其用于产生用于小型电器的振荡运动的。
With various relative lengths of the links, this four-bar linkage becomes a useful mechanism for converting uniform rotary to non-uniform rotary motion or continuous rotary to oscillatory motion.
改变这些杆的相对长度，这种四杆连杆机构就成为一种实用的机械装置，可以把等速转动转变为非等速转动，或者把连续转动转变成振荡运动。
Such a repetitive motion is said to be oscillatory or periodic. Many other examples might be cited;
这种往复运动也叫摆动或周期性运动。可以有很多例子证实；
