Impedance Adjusting Device

摘要

The present invention is an impedance adjusting device and includes a power output port, a ground terminal, a capacitor assembly including at least one capacitor, and a power output port. The power input port is electronically connected to a power converting circuit of a switching power supply, and the capacitor is electronically connected between the power input port and the ground terminal. The capacitor is connected in parallel to an output capacitor of the power converting circuit to stabilize an impedance of the switching power supply when an audio signal is played at different frequencies. Therefore the audio signal can be played without distortions.
