AUDIO DATA TRANSMISSION SYSTEM, AUDIO DATA TRANSMISSION APPARATUS, AND ELECTRONIC SIGNATURE TOKEN

摘要

An audio data transmission system, an audio data transmission apparatus for a mobile terminal and an electronic signature token are provided. The electronic signature token includes a modulating module configured to modulate audio data to be transmitted into an analog waveform signal using at least two modulation modes to generate audio data frame streams in the at least two modulation modes; a splicing module configured to splice the audio data frame streams in the at least two modulation modes into an audio data stream; a transmitting module configured to transmit the audio data stream to a mobile terminal in one transmission via an audio interface of the electronic signature token.
