摘　　要：根据音乐发生的机理,将复杂可编程逻辑器件作为发生音乐的核心器件,用高速集成电路硬件描述语言编程描述发生的音乐乐谱,配合周边硬件电路,由电声转换发声器接收信号,从而发出音乐声,实验表明,采用该方法设计的音乐发生器成本低、修改方便.According to the principle of making music, complex programmable logic device （CPLD） is used as the key part of music generator and the music book is described by very high speed integrated circuit hardware description language （VHDL） program. And then the music is generated by using electro-acoustic device to receive the signal, cooperating with the corresponding software circuit. Experiments vali- date this music generator by using software and hardware simulations. This generator costs low and is easy to modify.
