Abstract
Disclosed herein is a linear vibration motor. The motor includes a casing surrounding the top and widthwise side of the motor, and a bracket surrounding the bottom and lengthwise side of the motor. A plate is provided on an inner surface of a side of the bracket and integrally has a cylindrical part to accommodate a coil. A mass body is provided in a central portion of the bracket and vibrates horizontally, a yoke is provided on a side surface of the mass body, and a magnet is mounted to a central portion of the yoke to be inserted into an internal space of the coil. A spring couples the plate with the yoke, thus transmitting vibratory force to the motor. An extension part extends from an end of the spring, and a bearing is provided on an end of the extension part, thus minimizing friction with the casing.
