摘　　要：为了提高皮肤听声器对声音信号的识别能力,提出了基于摩尔斯编码的五通道异步皮肤听声器。利用计算机处理语音信号,查找相应的摩尔斯编码,由信号发生器产生编码对应的电压序列,采用五通道异步输出方式来刺激皮肤,可以辨析不同的语音。实验结果表明,基于摩尔斯编码的五通道异步皮肤听声器提高了对语音信号识别的准确性。进一步证实了将摩尔斯编码运用在皮肤听声器中是可行的。To enhance the identification capacity of the skin-hearing aid for voice signals, the five-channel asynchronous skin-hearing aid based on Morse encoding method is proposed.Using computer processing voices, seeking the corresponding Morse code, the voltage sequences are generated by the signal generator, using five-channel asynchronous output to stimulate skin, different signals of voice can be distinguished.The experimental results indicate that the distinguishing accuracy of skin hearing can be enhanced obviously.Furthermore, it also proves the feasibility of applying Morse code into skin-hearing.
