clap switch

The Voice Electric (FC52) converts sound into electrical signals. The FC52 utilizes a high-gain glucose amplifier to amplify audio signals. When a clapping sound occurs, the sound signal is transformed into electrical signals and fed into the inverting input of the FC52, resulting in an amplified output. Keywords include Voice Electric FC, 51base/dianl, 15V/3.5A, and a 52W switching power supply circuit.
