Problems solved by technology

The disadvantage of this solution is: the wireless transmission of data cannot be realized
The disadvantage of this solution is: it is based on ultrasonic waves, and the mobile phone needs to be modified, so it is not universal in practice
This invention is mainly for processing the received audio signal, and cannot solve the problem of short-distance electronic transactions

Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0023] like figure 2 and image 3 As shown, the audio data transmission system of the present invention includes two or more audio terminals, and an audio transmitter for converting application digital data signals into sound signals and an audio transmitter for converting application digital data signals into sound signals are arranged in the audio terminals. An audio receiver that converts sound signals into digital data signals.

[0024] like figure 2 As shown, the number of audio terminals is 2, and each audio terminal is provided with one audio transmitter and one audio receiver. In this way, two-way information transmission between two audio terminals can be realized, which facilitates the completion of relatively complex electronic transactions.

[0025] like image 3 As shown, the number of audio terminals is four, and each audio terminal is provided wi...

Abstract

The invention discloses an audio data transmission system, which comprises two or more audio terminals, and an audio transmitter for converting digital application data signals into voice signals and an audio receiver for converting voice signals into digital application data signals are arranged in each audio terminal. The invention also discloses an audio data transmission method; a rule of corresponding conversion between digital application data signals and voice signals is first established; at a transmitting end, digital application data signals are first converted into voice signals according to the rule of conversion, and the voice signals are then transmitted; and at a receiving end, the voice signals transmitted by the transmitting end are converted into the digital application data signals according to the rule of conversion. The invention also discloses the application of the audio data transmission system and the audio data transmission method in close range electronic transaction within one meter. By means of the invention, mobile phones and other mobile terminals can be utilized to directly carry out safe, convenient and quick close range electronic transaction.

Description

technical field [0001] The invention relates to a data transmission system, a data transmission method and its application, in particular to an audio data transmission system, a transmission method and its application using sound as a signal transmission medium. Background technique [0002] With the deepening of e-commerce applications, especially driven by the O2O (Online To Offline) model, the market needs to be able to meet the application capabilities of near-field transaction acceptance (such as electronic payment within 1 meter) through mobile terminals such as mobile phones. At present, the industry focuses on the application based on the SWP technical specification to realize NFC capability. There are two main implementation methods: (1) based on NFC-SIM card; (2) based on NFC-SD card. Whether using SWP or RFID technology, they all have necessary hardware support, such as: external RFID cards, remanufactured mobile phones, etc., which are not conducive to the univer...
