1. A sound signal-based local interactive platform system, comprising:

  • a wired/wireless AP (100) that has unique identification information for a location and that outputs a sound signal of a high frequency band in a preset variation pattern;

    a computer-readable recording medium, which is mounted in a smart terminal having a serial number, and which stores therein a program that when in an activated state, detects in real-time the serial number and the sound signal and transmits the unique identification information corresponding to the sound signal and the serial number to outside;

    a location server (300) that receives the serial number and the sound signal from the smart terminal, and that transmits the serial number and the unique identification information corresponding to the sound signal to the outside; and

    a content server (400) that receives the serial number and the unique identification information from the location server, and that transmits in real-time multi-formatted content information including audio data and video data, which is previously mapped with the unique identification information, to the smart terminal to be output,wherein in the wired/wireless AP, one or more inversion interval values for inverting an output of the sound signal are preset, a variation time for a section in which the sound signal is inverted according to an inversion interval value selected from among the one or more inversion interval values is preset, and when two or more inversion interval values are preset, the variation pattern is preset by inverting the output of the sound signal sequentially depending on the two or more inversion interval values on every occurrence of overflow exceeding the variation time.
