Abstract
An interactive music tag system and an interactive method thereof are provided in the present invention. The interactive method is adapted for an interactive music tag and an interactive music tag reader. The method includes: when the interactive music tag is close to the interactive music tag reader, outputting an wireless energy to the interactive music tag and outputting an audio envelop signal to the coil of an LC resonant circuit such that the analog audio signal is transmitted to the interactive music tag; when the interactive music tag reader controls the interactive music tag, modulating a control signal into the wireless energy; when the interactive music tag receives the control signal through the LC resonant circuit, controlling the output status of the audio envelop signal according to the control signal.
