1. An apparatus for interacting amusement, comprising:

  • an acoustic receiver for receiving an external acoustic wave signal and transferring the external acoustic wave signal into an acoustic signal;

    a decoder, which is coupled to the acoustic receiver and receives the acoustic signal, wherein the acoustic signal has a high-frequency modulation signal, the decoder decodes the high-frequency modulation signal into a complete packet message according to a specific decoding procedure; and

    an interaction generating apparatus, which is coupled to the decoder, receives the complete packet message, and generates an interaction according to the message,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 acoustic signal includes the high-frequency modulation signal, the decoder converts the acoustic signal into a digital signal, the decoder analyzes a frequency spectrum of the digital signal to output a frequency envelope, the decoder generates binary data stream according to a clock signal and the frequency envelope, and the decoder directly extracts the complete packet message from the binary data stream without any de-spreading processing.
