Toy synchronization method, toy synchronization file and toy

The invention discloses a toy synchronization method, a toy synchronization file and a toy. The toy comprises multiple output modules. The toy synchronization method is used for synchronization of output signals of at least two output modules and comprises the steps of reading a pre-defined synchronization file when an acoustical signal is output, wherein the synchronization file defines a time point and a data code of the other output signal on the time point,; then analyzing the data code and outputting a corresponding output signal. The other output signal contains patterns of an expression module or motor actions. The expression module consists of an electronic paper display module and can display multiple patterns for expression simulation under electrical driving.
