description A lightning protection device for sound equipment comprises an alternating current contactor used for connecting an indoor power amplifier and an outdoor sound box in series, a high-voltage detection control circuit board used for controlling on-off of the alternating current contactor and a lightning arrester, and the outdoor sound box can discharge electricity to the ground through the lightning arrester. The alternating current contactor, the high-voltage detection control circuit board and the lightning arrester are arranged in the shell; the lightning arrester comprises a plurality of zinc oxide lightning arresters; and two ends of the zinc oxide lightning arrester are supported by an insulating plate erected in the shell. According to the principle of the utility model, after protector equipment is powered on, the relay K1 in the circuit is closed, the alternating current contactor is controlled to be switched on, and the lightning arrester works normally; when the high-voltage detection control circuit
