Audio data transmission system, audio data transmission device and electronic sign tool

Abstract

The invention provides an audio data transmission system, which comprises a first device and a second device, wherein the first device is connected with the second device through an audio interface, the first device is used for modulating audio data to be transmitted through at least two modulation ways so as to generate audio data code streams of at least two modulation ways, the audio data codestreams of the two modulation ways are spliced into one audio data stream, and the audio data stream is transmitted to the second device in one step through the audio interface. Due to the adoption of the system, rapid interaction of the data streams can be realized, the success rate of the data transmission can be greatly increased, the probability of the data transmission failure caused by distortion degree of the data in the interaction process also can be reduced, and the data interaction quality can be improved. The invention also provides an audio data transmission device for a mobile terminal and an electronic sign tool.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to 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 mobile terminals and different electro...

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.
