1. audio playing apparatus, it comprise controller, storage medium andHost connector is connected for the exchanges data that realizes audio playing apparatus and operating system with main frame;

  • The MP3 decoding chip is used for the audio digital signals that is transmitted by controller according to the decoding of MP3 data layout;

    The D/A switch module is used for and will be converted to the simulating signal that can realize that audio frequency is play by the decoded digital signal of MP3 decoding chip;

    It is characterized in that, this audio playing apparatus also is provided with the infrared data transmission module, for the data transmission that realizes between two or more audio playing apparatus that possess the infrared data transmission function, described infrared data transmission module comprises;

    the logic interfacing module, be used for to realize communicating by letter between infrared data transmission module and the MP3 decoding chip;

    The infrared coding module is used for and will encodes according to the infrared coding pattern through the decoded digital signal of MP3 decoding chip;

    Infrared transmission module is used for emission through the digital signal of infrared coding;

    Infrared receiving module is used for receiving the digital signal through infrared coding;

    And the infrared decoding module, be used for and will decode according to the infrared decoding pattern through the digital signal behind the infrared coding, andWherein, described audio playing apparatus is configured to, controller steering logic interface module will be sent to the infrared coding module through the decoded digital signal of MP3 decoding chip, the infrared coding module is encoded according to the infrared coding pattern through the decoded digital signal of MP3 decoding chip for above-mentioned, and outwards launch through the digital signal behind the infrared coding above-mentioned by infrared transmission module;

    OrReceive through the digital signal behind the infrared coding by infrared receiving module, the infrared decoding module is decoded according to the infrared decoding pattern for above-mentioned digital signal through infrared coding, and controller steering logic interface module will be sent to through the digital signal behind the infrared decoding MP3 decoding chip.
