Multi-sensory gaming desk with audio-visual synchronization system
View Patent ↗The present disclosure belongs to the technical field of furniture, in particular to a multi-sensory gaming desk with an audio-visual synchronization system, comprising a desktop assembly, including a desktop panel and light guide grooves arranged along edges of the desktop panel; LED light strips embedded in the light guide grooves; and a control switch. The present disclosure realizes a 270° surrounding light effect through the design of U-shaped three-sided LED light strips, and achieves the music rhythm response by combining the voice-controlled pickup circuit with the light strip control IC, and the light can dynamically change with the audio rhythm. The combination of the ergonomic inclined control panel with the three-key physical switch is adopted to facilitate switching between multiple color modes and pickup direction modes.
