1. A method for interacting amusement, the method comprising the steps of:

  • providing an external acoustic wave signal;

    adding a high-frequency modulation signal to the external acoustic wave signal;

    providing an interacting amusement apparatus having an acoustic receiver;

    receiving the external acoustic wave signal using the interacting amusement apparatus;

    decoding the high-frequency modulation signal into a complete packet message; and

    generating an interaction according to the complete packet message using the interacting amusement apparatus,wherein a carrier frequency of the high-frequency modulation signal is higher than 17 KHz, and the high-frequency modulation signal is a narrow-band modulated signal,wherein, the external acoustic wave signal includes the high-frequency modulation signal, and the step of decoding the high-frequency modulation signal into the complete packet message further comprises;

    converting the external acoustic wave signal into a digital signal;

    analyzing a frequency spectrum of the digital signal to output a frequency envelope;

    generating a binary data stream according to a clock signal and the frequency envelope; and

    directly extracting the complete packet message from the binary data stream without any de-spreading processing.
