Design of Music Synthesizer Based on
Single Chip Microcomputer
Abstract: This paper introduces the AT89C2051 micro-controlier to control chip, the combination of an LM386 to design a single-chip synthesizer music. The input of DO,RE,MI,FA,SO,LA,SI different tones is perfumed by 4×4 keyboards. The scale signal is enlarged by frequency power amplifier LM386, and then it drives speaker to send out different scale. The detailed circuit and program is presented.
