The invention relates to a vibration generator having at least one shaft which can be driven in a rotating manner and on which at least one unbalanced unit is arranged that is constructed of at least two weight elements, of which a first weight element is firmly mounted on the shaft and a second weight element is supported in a radially adjustable manner which, depending on the speed of rotation of the shaft, is adjustable between a radially internal first position and a radially external second position. According to the invention a locking means is provided, through which the adjustable second weight element is secured in the first position up to a predetermined triggering speed of rotation of the shaft and, on reaching the triggering speed of rotation, is released and adjustable.
