Abstract
A touchpad includes a substrate, an elastic bracket and an actuating device. The substrate has a first surface and a second surface. The elastic bracket is located beside the second surface of the substrate. The actuating device includes a first actuating member and a second actuating member. The first actuating member is located near the second surface of the substrate. The second actuating member is aligned with the first actuating member and fixed on a side of the elastic bracket facing the substrate. The first actuating member and the second actuating member are movable relative to each other in response to a magnetic field force. Consequently, a relative vibration between the substrate and the elastic bracket is generated. The first actuating member includes at least one first coil. Each of the at least one first coil is spirally wound to form a first hollow region.
