Abstract
A touch module includes a base plate, a magnet, a touchpad and a magnetic board. The magnetic board includes a first wiring layer, a second wiring layer and a third wiring layer. The magnet is installed on the base plate. The touchpad is located over the base plate. The magnet is covered by the touchpad. The magnetic board is arranged between the touchpad and the magnet. The first wiring layer, the second wiring layer and the third wiring layer are in parallel with each other and stacked on each other. The second wiring layer is arranged between the first wiring layer and the third wiring layer. The first wiring layer is connected with the second sensing line through the third wiring layer. The first sensing line, the second sensing line and the third sensing line sense a magnetic field of the magnet and generates a vibrating effect.
