The music chip is a relatively simple voice circuit. It can generate various music signals through the internal oscillation circuit and the external connection of a small number of discrete components. The music chip is an important branch of voice integrated circuits and is currently widely used in music cards, electronic toys, electronic clocks, electronic doorbells, household appliances and other occasions.
N9300 MP3 music chip
What parts does a music chip consist of?
The music chip consists of the following parts: logic control circuit, oscillator, address counter, music symbol rhythm memory (ROM), scale generator, output controller. Its principle is: the signal generated by the oscillation circuit is used by each power circuit; the control circuit records the code from the memory chip, and controls the metronome and tuner to work in coordination according to the code to produce corresponding music output.
