A vibration generator for a vibrating pile driver includes a generator housing, in which a generator gear mechanism is arranged, which includes at least two parallel shafts rotatably mounted in bearings held by the generator housing, and connected to at least one drive to put them into rotation, and to at least two imbalance masses attached to one or more of the shafts. The at least one drive is formed by a drive unit, in each instance, which includes an electric motor and a drive gear mechanism connected to the motor. The drive unit is positioned on the generator housing, on the outside, offset from the bearings held by the generator housing, in the direction of the axes of rotation of the shafts, and not axially between two bearings of a shaft. The drive gear mechanism is connected to at least one of the shafts.
