Abstract
A connection structure connects to an electronic device and a projection component that connects to the electronic device through the connection structure to project a target projection content from the electronic device. The projection component includes a transmission module, an output interface, a direction change mechanism, and a linkage apparatus. The transmission module receives the target projection content. The output interface outputs an initial light ray of the target projection content. The direction change mechanism directs the initial light ray as an output light ray in one of a plurality of output directions. The linkage apparatus is coupled to the connection structure and the direction change mechanism to drive the direction change mechanism to change the output direction of the output light ray from a first output direction to a second output direction in response to a variation in a relative arrangement between the projection component and the electronic device.
