Apparatus, method and system for interacting amusement

摘要

The present invention relates to an apparatus and a method for interacting amusement. The apparatus includes an acoustic receiver, a decoder and an interaction generating apparatus. The acoustic receiver receives an external acoustic wave signal and transfers the external acoustic wave signal into an acoustic signal. The decoder receives the acoustic signal. When the external acoustic wave 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. The interaction generating apparatus receives the complete packet message, and generates an interaction according to the message.

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.
