Abstract

The invention provides a data transmission method based on sound wave. The method comprises the following steps: to begin with, obtaining original data; then, enabling the original data to be encoded into 17.5 kHz-19.5 kHz audio signals according to a preset frequency mapping table; and finally, playing the audio signal to enable the audio signal to be sent to a receiving end in the form of a sound wave signal, and to be received, decided and processed by the receiving end. Compared with the prior art, the method sends near ultrasonic signals in the 17.5 kHz-19.5 kHz high frequency band, thereby reducing influence of environment noise on the sound wave to the maximum degree, and preventing signal distortion and data loss; and the method achieves an optimum balance effect among availability to most of intelligent mobile phones, environment noise processing and high and low near ultrasonic waves tolerable for ears, thereby ensuring reliability and safety of data transmission, transmission efficiency and hearing comfortableness.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data transmission method based on sound waves, a data transmission device based on sound waves and a data transmission system based on sound waves. Background technique [0002] There are three major advantages to using sound waves for short-distance data transmission, especially with the popularity of smartphones. The first is its good adaptability. Nearly 100% of smartphones on the market support sound wave transmission and reception. In comparison, Bluetooth, infrared, NFC (Near Field Communication, near field wireless communication) and other penetration rates are low, such as NFC At present, only some high-end mobile phones support it; the second is that its application is not controlled by the device manufacturer, and software vendors can develop corresponding software; the third is that it does not need to be associated and paired before short-distance data transmi...
