Problems solved by technology
[0003] However, there are very few means of audio communication at present, so there is no suitable way to be compatible with the communication between different mobile terminals and different electronic signature tools at the same time
[0004] Moreover, since the communication parties are not necessarily fixed, and both communication parties may have different audio transmission characteristics, therefore, in the transmission process of audio data, if no matching modulation method and demodulation method are used, the data will be The interaction speed is slow, and the interactive data is easy to be distorted and distorted.

Provided is an audio data transmission method comprising the following steps: a first device generates multiple pieces of audio waveform data of different frequencies; the first device splices the multiple pieces of audio waveform data into one audio waveform data stream; the audio waveform data stream is transmitted in a single instance within a same time reference system to a second device via an audio interface of the first device, thus allowing for rapid acquisition of the spectrum characteristics of an audio data communication link, greatly reducing the loss of fidelity in exchanged data, increasing the success rate in data transmission, and improving the quality of data exchange. Also provided in the present invention are an audio data transmission system, an audio data transmission device for use in a mobile terminal, and an electronic signature tool.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an audio data transmission method, an audio data transmission system, an audio data transmission device for a mobile terminal and an electronic signature tool. Background technique [0002] Currently, when audio data is transmitted through an audio interface, different mobile terminals have different audio transmission characteristics. If it is necessary to be compatible with the audio transmission characteristics of different mobile terminals, the device that communicates with the mobile terminal (such as an electronic signature tool) needs to automatically Experiment with audio data of different modulation schemes to find the most suitable modulation scheme for use with each different mobile terminal. [0003] However, there are very few means of audio communication at present. Therefore, there is no suitable way to be compatible with the communication between different mob...
