Horizontal linear vibrator

A horizontal linear vibrator, comprising:

• a casing defining an internal space therein;
• a bracket disposed under the casing, with a cylindrical coil provided on the bracket;
• a vibration unit comprising:
• a yoke provided with a magnet attached to an upper surface thereof, the yoke being open on a lower end thereof;
• and a weight coupled to an outer surface of the yoke;
• and
• springs coupled to both ends of the casing or the bracket, the springs elastically supporting the vibration unit to allow the vibration unit to vibrate in the horizontal direction,
• wherein the yoke comprises:
• an upper plate provided on a lower surface thereof with the magnet;
• a side plate bent downwards from the upper plate;
• and a bottom plate bent inwards from the side plate, the bottom plate extending a predetermined length parallel to the upper plate, with an opening being formed through a portion of the bottom plate, and
• a circuit board is provided on an upper surface of the bracket, and a coil guide perpendicularly protrudes from an upper surface of the circuit board, so that the cylindrical coil is supported by the coil guide, and
• the coil guide supports the cylindrical coil such that the cylindrical coil is disposed in the yoke through the opening of the bottom plate of the yoke.
