摘　　要：随着移动设备的不断发展,安卓系统日益普及。由于NFC芯片硬件成本较高,大量安卓设备没有配置,导致利用NFC芯片进行近场通信的应用范围存在局限。为解决近场通信的普适性问题,本文给出了一种利用移动设备内置扬声器和麦克风进行声波近场通信的软件方案,介绍了在安卓手机上实现的原型系统的设计,以及采用声波调幅传输二进制信息的调制、解调算法。对该方案进行了兼容性、识别率、抗干扰等方面的测试,实验结果表明声波通信软件具有硬件要求低、成本低、传输可靠等优点,具有良好的应用前景。With the development of mobile devices,Android systems are becoming increasingly popular.Due to the high cost of NFC chip hardware,a large number of Android devices are not configured,resulting in limitations in the application range of the near field communication by using the NFC chip.In order to solve the general problem of near field communication.This paper introduces a schema which uses speaker and microphone built-in mobile device for the near field communication,presents the design of the prototype APP of Android phone,describes modulationdemodulation algorithm using sonic-camplitude modulation to transmit binary information.The program has been tested in terms of compatibility,recognition rate,anti-interference etc.The results show some advantages,like low hardware requirements,economy,reliability.This method has good prospects for application.
