An apparatus for treating tinnitus through stimulating multiple acupoints with a multi-electrode electric pulse. A control terminal controls a first MCU micro-control module and the second MCU micro-control module to allow the second MCU micro-control module to output a variety of different pulse signals, and the different pulse signals are respectively output to an electric-pulse output circuit and an electric-pulse conversion circuit. The pulse signal output to the electric-pulse output circuit is a carrier signal. The pulse signal output to the electric-pulse conversion circuit is converted to a modulating wave by the electric-pulse conversion circuit. The modulating wave and the carrier signal are both output to the electrical-pulse output circuit. After a modulation, a transcutaneous electric-pulse stimulation signal is output by an output port, and is transmitted to an electrode sheet attached to the corresponding acupoint on human body through an electrode wire to stimulate the acupoint.
