The present disclosure relates to a multi-target electrical stimulation circuit, an electrical stimulator, and a signal output method therefor. The electrical stimulation circuit comprises a control module, multiple electroencephalography collecting modules, and multiple stimulation adjusting modules. Each electrode is correspondingly provided with one electroencephalography collecting module and one stimulation adjusting module. Different electrodes are used for stimulating different targets. The electroencephalography collecting modules are used for collecting electroencephalography signals on the corresponding electrodes and transmitting to the control module. The control module is used for acquiring a brain rhythm phase signal on the basis of an electroencephalography signal received, and outputting a stimulation signal at a set waveform phase point when the brain rhythm phase signal is phase-locked. The stimulation adjusting module is used for adjusting, on the basis of the stimulation signal received, an electroencephalography stimulation signal outputted to the corresponding electrodes. The technical solution of the present invention favors the implementation of electrical stimulation with respect to multiple targets, and implements time-locked matching of electrical stimulation with respect to the multiple targets.
