The invention discloses a suspension projection interactive system which is composed of a magnetic suspension control base part and a suspension interaction projection part. Each of the two assemblies is divided into a magnetic suspension module, a wireless charging module, an interactive touch module, a micro projection module and a core control panel module. The magnetic suspension control base part is mainly used for suspending the suspension interaction projection part on the upper portion and transmitting electric energy for the suspension interaction projection part in a wireless mode. The suspension interaction projection part is mainly used for achieving multi-angle projection, network communication and a touch interaction function. The problems that due to the fact that current micro projection is prone to be influenced by vibration, the projection picture flutters, a camera cannot be automatically focused, and a projection area cannot be automatically subjected to keystone correction can be effectively solved, meanwhile, a projection interaction operation means is provided for a user through linear lasers, a camera and micro projection, therefore, a brand-new suspension projection interactive experience mode is presented, projection gets rid of external disturbance, and a new market application thought of suspension micro projection interaction is opened.
