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.
