Abstract
A displacement type generator including a magnet set and a coil set is provided. The magnet set includes a magnet with unidirectional magnetization and a first multi-polar magnetic structure, wherein the first multi-polar magnetic structure is disposed on the magnet. The coil set includes a magnetic center pole, a coil and a second multi-polar magnetic structure. The coil is wound on the magnetic center pole. The second multi-polar magnetic structure is disposed on the magnetic center pole and is adjacent to the first multi-polar magnetic structure. As a relative movement is generated between the magnet set and the coil set, the magnetic flux changes and causes the coil to output an induced voltage.
