Abstract

The invention provides laser cinema equipment. A circuit system framework of electronic equipment comprises a shell; a ground plane plate is mounted on a base of the shell; the ground plane plate is provided with a bottom plate and side plates perpendicular to the bottom plate; a light source and an optical machine are mounted on the bottom plate; the circuit system framework further comprises atleast two circuit boards; the at least two circuit boards are mounted on the bottom plate and the side plates; the at least two circuit boards are grounded; and the circuit board mounted on the bottomplate is a power supply board. According to the laser cinema equipment provided by the embodiment of the invention, one complete and uniform large-area ground plane plate is formed by the bottom plate and the side plates, so that a complete ground circuit can be provided for backflow of an electric signal, and the serious EMI problem caused by the electronic equipment is prevented.

Description

technical field [0001] The invention relates to the field of electronic products, in particular to an electronic equipment circuit system architecture and laser cinema equipment. Background technique [0002] With the development of modern society, the functions of household electronic equipment are becoming more and more abundant; at the same time, in order to facilitate installation and use, the volume of electronic equipment is also getting smaller and smaller. For example, laser cinema TV, which is currently attracting much attention, has the functions of cinema, smart TV and home audio, and is welcomed by the home and commercial markets. [0003] Laser theater TV products use the structure of a projector, but at the same time have the function of a smart TV. In addition to modules such as optical engines, radiators, and fans, the internal structure also includes power boards, TV boards, display boards, wireless fidelity (Wireless Fidelity, referred to as: WIFI) & Bluet...
