Abstract
Disclosed is a linear power generation device that exhibits reduced vibration and noise, thereby having excellent quietness, and that concentrates a magnetic flux on a driving body, thereby greatly increasing the output thereof and improving the overall operation efficiency thereof, wherein the linear power generation device includes a stator yoke housing, a stator coil disposed in the stator yoke housing, a linear driving magnet body configured to perform forward-backward movement operation due to interaction with the stator coil using a generated magnetic flux, and a linear driving body output increasing element disposed on one side of the interior of the stator yoke housing and configured to concentrate a magnetic flux of the linear driving magnet body on the stator coil while preventing leakage of the magnetic flux to increase the driving force of the linear driving magnet body.
