Abstract
A linear vibration motor for fixing a ring-shaped coil provided within the linear vibration motor using a simpler structure. A linear vibration motor in which an upper casing and a bracket are configured to have an integrated shape and fixed to the inside or upper side of the coil to form magnetism, thereby facilitating fabrication due to a simple structure, preventing a reduction of a vibration power through a small space, and minimizing a rise of a material cost. Accordingly, the coil within the internal space of the casing is stably fixed by providing a structure for fixing the coil through the simple process of the bracket itself. Furthermore, since parts forming the vibration motor and the linear vibration motor are integrated, an assembly process is simplified, performance is satisfied by realizing a reduced production cost, and a working process and price competitiveness is secured.
