Toy eye with changeable pupil thereof

Abstract

A toy eye includes a front cover, a rear cover and an iris assembly. The front cover defines a first through hole. The rear cover is coupled to the front cover to cooperatively define a receiving cavity. The iris assembly is received in the receiving cavity and includes a fixed supporting portion, an elastic pupil portion, a metallic body and an electromagnet. The supporting portion defines a second through hole. The pupil portion is attached to the supporting portion. The metallic body is fixed to the pupil portion and runs through the second through hole. The electromagnet is fixed to the rear cover and aligned with the metallic body.

1 . A toy eye comprising:
 a front cover defining a first through hole;   a rear cover coupled to the front cover to cooperatively define a receiving cavity; and   an iris assembly received in the receiving cavity and comprising:
 a fixed supporting portion defining a second through hole; 
 an elastic pupil portion attached to the supporting portion; 
 a metallic body fixed to the elastic pupil portion and running through the second through hole; and 
 an electromagnet fixed to the rear cover and aligned with the metallic body; 
   wherein the electromagnet is activated and produces a magnetic field, the metallic body is pulled by the electromagnet due to the existence of the magnetic field, the pupil portion is stretched by the metallic body and the size of the pupil portion is changed.
