Abstract
Disclosed is a waterproof electronic device which includes a casing, a magnetic induction switch and a button response circuit arranged in the casing. The magnetic induction switch includes a magnetic induction element arranged at the inner side of the casing and a magnetic element arranged at the outer side of the casing. The magnetic induction element includes N-pole and S-pole magnetic sensors. The magnetic element is provided with an N pole and an S pole. Positions of the N pole and the S pole of the magnetic element face directly the positions of the N-pole and S-pole magnetic sensors of the magnetic induction element respectively. The magnetic induction element is electrically connected with the button response circuit. The magnetic element is operated to be away from the magnetic induction element for a specific range so that a magnetic-field action of the magnetic element triggers the N-pole magnetic sensor and the S-pole magnetic sensor at the same time and thus the button response circuit executes a corresponding button function in response. The magnetic induction switch eliminates interferences from outside magnetic fields and prevents false operations so that the electronic device with the magnetic induction switch has an excellent waterproof effect.
