After step 3:mix3018 audio-frequency power amplifier receives the analog signal of L channel negative pole under the analog signal of the R channel negative pole under TF mode card and the analog signal of R channel positive pole and TF mode card and the analog signal of L channel positive pole, after mix3018 audio-frequency power amplifier carries out power amplification to the analog signal of L channel negative pole under the analog signal of the R channel negative pole received under TF mode card and the analog signal of R channel positive pole and TF mode card and the analog signal of L channel positive pole, again the analog signal of the R channel negative pole after power amplification, the analog signal of R channel positive pole, the analog signal of L channel negative pole and the analog signal of L channel positive pole are sent to the R channel negative pole of loud speaker respectively, the R channel positive pole of loud speaker, the L channel negative pole of loud speaker and the L channel positive pole of loud speaker are play,
Step 4: when MP3 sends audio data stream by USB interface to AC1096 decoding chip, AC1096 decoding chip is delivered to the R channel digital-to-analogue inverted signal pin being designated 5 of the analog signal of the R channel positive pole in the analog signal of the R channel negative pole in audio data stream and audio data stream by AC1096 decoding chip under TF mode card in mix3018 audio-frequency power amplifier, and under TF mode card, the analog signal of the analog signal of L channel negative pole and L channel positive pole is delivered in mix3018 audio-frequency power amplifier by the L channel digital-to-analogue inverted signal pin being designated 4 of AC1096 decoding chip,
After step 5:mix3018 audio-frequency power amplifier receives the analog signal of L channel negative pole under the analog signal of the R channel negative pole under TF mode card and the analog signal of R channel positive pole and TF mode card and the analog signal of L channel positive pole, after mix3018 audio-frequency power amplifier carries out power amplification to the analog signal of L channel negative pole under the analog signal of the R channel negative pole received under TF mode card and the analog signal of R channel positive pole and TF mode card and the analog signal of L channel positive pole, again the analog signal of the R channel negative pole after power amplification, the analog signal of R channel positive pole, the analog signal of L channel negative pole and the analog signal of L channel positive pole are sent to the R channel negative pole of loud speaker respectively, the R channel positive pole of loud speaker, the L channel negative pole of loud speaker and the L channel positive pole of loud speaker are play.
