Abstract: The present invention relates to an electric drum, which comprises a dual-gear reduction mechanism that comprises at least one stage of sun dual-gear, N planetary dual-gear sets and a gear ring; the at least one stage of sun dual-gear is coaxially arranged with an output gear shaft of a motor; the N planetary dual-gear sets surround the at least one stage of sun dual-gear, and the structure of each planetary dual-gear set comprises a planetary pin, on which at least one stage of planetary dual-gears and an output planetary gear are sequentially sleeved in an axial direction; two ends of the planetary pin are fixedly connected with fixing parts in the drum body; the various stages of sun dual-gears are sequentially engaged with the planetary dual-gears, and finally the drum body is driven to rotate via the engagement between the output planetary gear and the gear ring; the N planetary dual-gears in each stage are evenly distributed around the sun dual-gear, and N is greater than or equal to 3.
