The invention relates to a poker vibrator for compressing concrete. The poker vibrator comprises a vibrating housing that accommodates an unbalanced mass and an electromotor, an insulating plastic tube that links the vibrating housing to a switch cover, an electric cable that links the switch cover to a connector shell and that bears a power plug, and a frequency converter that supplies the current for the electromotor. The poker vibrator is characterized in that the switch is arranged separately from a coupling piece on the tube and not on the electric cable and/or in that at least some of the components of the frequency transformer are arranged in a transformer housing provided between the switch housing and the powerplug.
