Abstract
The present invention provides a horizontal linear vibrator which can reduce the thickness but increase vibration strength 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. The bracket is disposed under the casing. A cylindrical coil is provided on the bracket. The vibration unit has a magnet, a yoke and a weight. The yoke contains the magnet therein and is open on the lower end thereof. The weight is coupled to the outer surface of the yoke. The springs are coupled to 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.
