A device for generating a circular oscillation or a directional oscillation is provided. The device provides a circular oscillation, or, if two parallel main shafts rotating synchronously in opposite directions are coupled, a directional oscillation, each main shaft having unbalance weights and a coupling between the unbalance weights and the oscillation amplitude of the exciter force per main shaft being continuously adjustable between a minimum value and a maximum value using an adjustment unit via the relative rotation of the unbalance weights toward or away from one another. The device includes unbalance weights that are mounted on the main shaft so they are rotatable thereon, and the coupling comprises a transmission medium connected rotationally fixed to the main shaft, which is composed so that it acts as a driver on the unbalance weights and also causes a pivoting of the unbalance weights in opposite directions upon the adjustment of the oscillation amplitude of the exciter force.
