利用扬声器将编码数据以各数据帧的形式传送至外界；Use the speaker to transmit the encoded data to the outside world in the form of each data frame;
通过麦克风接收各数据帧；Receive each data frame through the microphone;
对各数据帧进行完全解码，得到解码数据；Completely decode each data frame to obtain decoded data;
将解码数据转化为二维码矩阵，重新生成对应的二维码并获取该二维码的原始信息。Convert the decoded data into a two-dimensional code matrix, regenerate the corresponding two-dimensional code and obtain the original information of the two-dimensional code.
具体地，该装置可以以软件APP的形式被设计出，从而供各智能终端进行下载，比如发送二维码的智能终端可通过该APP传送二维码，接收二维码的智能终端通过该APP接收并还原二维码，从而实现传输，可见非常方便，只需用智能终端就可实现。Specifically, the device can be designed in the form of a software APP, so as to be downloaded by each smart terminal. For example, a smart terminal sending a QR code can send a QR code through the APP, and a smart terminal receiving a QR code can use the APP to download the QR code. It can be seen that it is very convenient to receive and restore the QR code to realize the transmission, and it can be realized only with a smart terminal.
