1. A multi-fan system, comprising:
a control source circuit, comprising:
a driving signal output terminal, wherein the control source circuit outputs a device driving signal string through the driving signal output terminal, wherein the device driving signal string comprises a plurality of device driving signals with different identification codes; and
a plurality of electronic devices, commonly coupled to the driving signal output terminal, each comprising:
a driving signal input terminal, electrically connected to the driving signal output terminal;
a fan;
a light emitting element group; and
a controller, coupled to the fan, the light emitting element group, and the driving signal input terminal, and configured to receive a corresponding device driving signal in the device driving signal string through the driving signal input terminal, wherein the corresponding device driving signal has a corresponding identification code corresponding to a corresponding electronic device among the electronic devices, and controls an operation of at least one of the fan and the light emitting element group based on the corresponding device driving signal.
