What Is AC Interface Distortion?

- Sep 04, 2018-

The AC interface distortion is caused by the back electromotive force of the speaker being fed back to the circuit through the line. The methods to improve this distortion are as follows: 1) reduce the number of circuit stages, increase the static working current of the circuit appropriately; 2) select a suitable speaker to make the damping coefficient more reasonable; 3) use a large-capacity high-quality power transformer, and appropriately improve the capacity of the filter capacitor, a small-capacity CBB capacitor is connected in parallel with the filter capacitor.
