Voice-controlled music socket circuit using NJM2072D (2)
Source: InternetPublisher:武林萌主 Updated: 2017/03/01
The circuit is shown in the figure. It is composed of the voice-activated special integrated circuit NJM2072D as the core, but the on and off of the socket XS1 is controlled by a two-way thyristor, and the sound circuit uses the negative level triggered integrated circuit KD-56020 that imitates animal sounds.
