Abstract
The present invention provides a horizontal linear vibrator which can reduce the thickness but increase the strength of vibrations while at the same time guaranteeing a sufficiently long lifetime and satisfactory responsivity. The horizontal linear vibrator includes a casing, a bracket, a vibration unit and springs. The casing defines an internal space therein. A first magnet is attached to an upper plate of the casing. The bracket is coupled to the lower end of the casing. The second magnet is attached to the bracket such that different poles of the first and second magnets face each other. The vibration unit has a weight, and a cylindrical coil which is provided in or under the weight. The springs are coupled to the sidewall plates of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.
