Abstract
An audio-frequency circuit for restraining EMI includes a substrate, an audio connector, an audio treatment chip and a grounding capacitor. Wherein, the substrate has an audio grounding area, an audio grounding line and a ground. The audio connector has an audio grounding terminal connected to the audio grounding area by the audio grounding line. In addition, the grounding capacity is disposed on the substrate and near the audio connector, and the grounding capacitor has a first terminal connected to the audio grounding line and a second terminal connected to the ground to eliminate EMI noise on the audio grounding line.
