Rotating mirror device and electronic equipment

The utility model discloses a rotating mirror device and electronic equipment, the rotating mirror device comprises a support, a reflector and a counterweight part, the support comprises a first surface and a second surface which are oppositely arranged, and a side surface connected with the first surface and the second surface; the reflector is arranged on the side surface of the bracket; the balance weight piece is arranged on the first surface and/or the second surface of the support, and the balance weight piece is an element formed after the flowable medium is solidified. According to the dynamic balance correction method, the rotating mirror device can be directly counterweighted by arranging the counterweight part on the rotating mirror device, so that dynamic balance correction of the rotating mirror device is realized, meanwhile, the counterweight part is formed by utilizing the flowable medium, the weight of the counterweight part can be accurately controlled, and thus the accuracy and efficiency of
