Variable paper-cut acoustic switch for tunable experiment site

A tunable deformation paper-cut sound switch for an experiment site comprises a spiral paper-cut structure, a micro-displacement structure and an electromechanical control system. The spiral paper-cutting structure is provided with a plurality of paper-cutting units, and the paper-cutting units are arranged on a plate body in an array mode. The micro-displacement structure is arranged below the spiral paper-cutting structure, the micro-displacement structure is provided with a plurality of micro-displacement units, the micro-displacement units are arranged in one-to-one correspondence with the paper-cutting units, and the micro-displacement units are connected with the paper-cutting units through electromagnetic attraction after being electrified and then control displacement deformation of the paper-cutting units; the electromechanical control system is used for controlling the three-dimensional deformation direction and degree of each paper-cutting unit through the micro-displacement structure so as to chan
