Electromagnetic remote control and control method thereof
First Claim
1. An electromagnetic remote control, wherein the electromagnetic remote control comprises a first rotary disc and a second rotary disc that is rotatably connected to the first rotary disc, wherein at least one first magnetic piece is disposed on the second rotary disc, at least one second magnetic piece is disposed on the first rotary disc, and polarity of a surface, facing the first rotary disc, of the first magnetic piece is the same as polarity of a surface, facing the second rotary disc, of the second magnetic piece;
- and the electromagnetic remote control further comprises a control circuit that correspondingly generates a remote control signal according to relative locations of the first magnetic piece and the second magnetic piece, the control circuit comprises a controller, a pressure sensor electrically connected to the controller and disposed on the first magnetic piece or the second magnetic piece, and a signal transceiver electrically connected to the controller, wherein when the pressure sensor detects that pressure increases, the controller controls the signal transceiver to generate and send a corresponding remote control signal.

Abstract
An electromagnetic remote control and control method thereof; when rotating a second rotary disc (20), the repulsive force between a first magnetic piece (30) on the second rotary disc (20) and a second magnetic piece (40) on a first rotary disc (10) is increased; when detecting increase in force on the second magnetic piece (40), transmitting a corresponding control instruction to a controlled device. The controlled terminal can be controlled by rotating the second rotary disc (20) without providing additional function keys, thus the electromagnetic remote control is small and easy to carry.
