AI Technical Summary
Existing docking stations are cumbersome to operate, making it difficult to quickly control external devices when both hands are occupied, and information retrieval is not real-time.
A voice expansion dock was designed, which integrates a voice control module, a video expansion module, a USB expansion module, and a display module. It controls the working mode of external devices through voice commands and integrates real-time information display function.
It enables quick control of external devices without manual operation, making it especially suitable for scenarios where both hands are busy, and supports real-time information query and display.
