The projection device includes a projection module, a controller, and an audio player. The controller is coupled to the projection module. The audio player is coupled to the controller. When the controller executes the prepare-for-sleep mode, the controller operates the projection module to dim a projection beam or to project a predetermined projection image and operates the audio player to play a predetermined sound.
