Abstract
A linear vibration generator in which a coil or a stator is fixed using a simple structure compared to a conventional technology. There is provided a linear vibration generator having advantages of a simplified assembly process and a low production cost by reducing the number of parts that form the inside of the vibration generation device through an improved bracket structure in which a protruding part functions as a central yoke. The protruding part can be easily fabricated by being pressed into a bracket using a press or deep drawing method, and a coil is fixed by a stable structure. There is an advantage of a low production cost.
