The role of sound by means of a magnetics toys , in particular the use of mutual adsorption of two magnetic impact and sound of the toy, the entire surface of magnetic body described as arc, and the magnetic surface of a smooth body surface, in theSmooth the surface so smooth hardened film processing, or even directly in the magnetic film formed on the surface smooth hardening; with the said two magnetic bodies attract each other in a free state, rapid rebound after the impact, and then attract crash, then rebounded in such mannerrepeated numerous times in a short time the impact and rebound, and a voice at the impact of the final result of energy depletion and rebound attributed to static, and thus stop the sound, while the use of film to make the products described in hardening resistance to impact, the number ofso as to enhance product life.
