Laser vibration arm for PET and PC material screen

The invention discloses a laser vibration arm for a PET and PC material screen, which comprises an electromagnet, a connecting plate is arranged on the electromagnet, a fixing groove is formed in the connecting plate, an L-shaped plate is mounted on the connecting plate, a sliding rail is mounted on the L-shaped plate through a bolt, a sliding block is sleeved on the sliding rail, a buckle is fixedly connected to the bottom of the sliding block through a bolt, and the buckle is fixedly connected to the bottom of the sliding block through a bolt. An adjusting bolt is installed on the top of the sliding block, and a magnet is installed on the electromagnet in a matched mode. Compared with the prior art, the screen laser speckle elimination system has the advantages that the control box of the screen laser speckle elimination system can adjust the vibration state of the electromagnet, and the maximum adjustable range of the vibration frequency is 30-100 Hz. And the maximum adjustable range of the voltage of the
