Abstract

The invention discloses a data sending method, a device, and an electronic device based on sound wave. The invention also provides a data transmission system based on sound wave. The data sending method based on sound wave comprises the steps of obtaining the sent data; obtaining the sound wave frequency sequence corresponding to the data to be sent based on the preset sound wave frequency mappingtable; generating a sound wave signal sequence after filtering processing based on the sound wave frequency sequence and the preset sending duration, wherein the sending duration is the time durationfor the sound wave signal corresponding to the single character; sending out the sound wave signal corresponding to the data to be sent based on the sound wave signal sequence after the filtering processing. The invention is advantageous in that the data sending method based on sound wave is adopted to send out the sound wave signal after filtering, which can effectively increase communication distance and enhance identification precision, and can prevent noise brought by frequency switching.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a sound wave-based data transmission method, device and electronic equipment. The present application also relates to a data receiving method, device and electronic equipment based on sound waves, and a data transmission system based on sound waves. Background technique [0002] With the continuous development of smart terminals, the ways of information transmission and interaction are becoming more and more diverse. Compared with Bluetooth, infrared data transmission, wireless network or other near-field communication methods, sound waves, as a near-field communication method, have strong real-time performance, no need for any external network connection, no high configuration and specific requirements , Simple and convenient, etc. Therefore, the data transmission method based on sound waves has been widely used. [0003] The patent application with publica...
