Abstract
A touch module includes a base plate, a first magnet, a second magnet, a touch pad, a first magnetic board and a second magnetic board. The first magnet and the second magnet are installed on the base plate and separated from each other. The touch pad is located over the base plate to cover the first magnet and the second magnet. The first magnetic board and the second magnetic board are separated from each other, located under the touch pad and coupled with the touch pad. The first magnetic board is aligned with the first magnet. The second magnetic board is aligned with the second magnet. The driving circuit is electrically coupled with the first magnetic board and the second magnetic board. The first magnetic board induces a magnetic field of the first magnet. The second magnetic board induces a magnetic field of the second magnet.
