The invention relates to an oscillatory system for a motorized drive unit for the generation of a rotary oscillatory movement having a first component and a second component able to oscillate with respect to one another around an axis of oscillation. In accordance with the invention, the oscillatory system has at least two elongate spring elements which are elastic at least in the direction of the rotary oscillatory movement and which each have two fastening points spaced apart from one another, with one respective fastening point being connected to the first oscillatory component, one respective fastening point being connected to the second oscillatory component and the connection line of the fastening points of at least one spring element and the connection line of the fastening points of at least one other spring element intersecting at an angle of intersection. The invention furthermore relates to a drive unit having an electromagnetic drive element in accordance with the invention and an oscillatory system in accordance with the invention and to a small electric appliance having a drive unit in accordance with the invention.
