Optical labyrinth with buzzer

The utility model relates to an optical maze with a buzzer. The optical maze comprises a maze body, the inner space of the maze body comprises a smoke detection chamber; a smoke inlet is formed in theside surface of the labyrinth body; a buzzer is fixedly arranged at the upper end of the labyrinth body in a penetrating mode. A pin of the buzzer penetrates into the smoke detection chamber; the shell of the buzzer is not in contact with the smoke inlet; the labyrinth body is provided with a through hole communicated with the outside; and the pins of the buzzer are electrically connected with the circuit board outside the labyrinth body through the through holes. According to the improved optical maze, the buzzer is arranged at the top of the maze body, smoke cannot be blocked when enteringthe smoke detection chamber from the smoke inlet in the side edge, and the smoke inlet effect is good; meanwhile, the buzzer and the labyrinth body are integrated, the overall structure is more compact, and miniaturization dev
