Vehicle-mounted voice passenger reminder device with microphone array

Abstract

This utility model relates to the field of bus technology, specifically to an in-vehicle voice passenger disembarkation reminder device with a microphone array. It includes a control console and three speakers. A control board is fixed to the top of the control console, and a switch and several microphones are mounted on the top of the control board in a matrix arrangement. A main control box is also installed inside the control console. Several pins are slidably connected to the left and right ends of the top plate of the main control box. The control console has corresponding and size-matched insertion holes inside. In this utility model, during installation, pushing the push handle retracts the pins, placing the main control box in the corresponding position on the control console, and then releasing the push handle allows the return spring to push the pins into the insertion holes for secure installation. During disassembly, simply pushing the push handle disengages the pins from the insertion holes, allowing for quick removal of the main control box without the need for tools, significantly saving maintenance time.
