The utility model relates to the technical field of LED driving, in particular to a music driving controller for full-color LEDs, a first full-color LED adopts a two-pin full-color LED, and the two-pin full-color LED adopts a current carrier technology, so that the first full-color LED can drive the full-color LEDs to play music according to received power supply energy and control signals transmitted by a master control MCU (Microprogrammed Control Unit). A logic chip in the first full-color LED controls the lighting opportunity and the color of a lamp bead of the first full-color LED by detecting the low-level pulse width time of a control signal, the main control MCU outputs different control signals according to the rhythm of music, the voltage, the pulse width and the like of the control signals are different, and the control signals can be controlled to be different. Therefore, the first full-color LED lamp is driven to make different responses according to music, and compared with a traditional four-pi
