A linear vibrator is disclosed. In accordance with an embodiment of the present invention, the linear vibrator includes a base, a coil unit, which is coupled to the base, a magnet, which is coupled to the coil unit such that the magnet can move relatively with respect to the coil unit, and a leaf spring, which is interposed between the magnet and the base and includes a plurality of plate-shaped members having center portions thereof being separated from one another and both respective ends thereof being coupled to one another. Thus, the linear vibrator can increase the range of displacement in the leaf spring and increase the magnitude of vibration in the linear vibrator.

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.

The horizontal linear vibrator includes a casing, a bracket, a vibration unit, a cylindrical coil and springs. The bracket is coupled to the casing to form an internal space. The vibration unit includes a weight, a pair of yokes and magnets. The weight has an opening therein. The yokes are disposed on the inner surfaces of the weight. The magnets are provided in the yokes such that different poles of the magnets face each other. The cylindrical coil is perpendicularly mounted to the bracket and disposed in space between the pair of yoke. The springs are coupled to both ends of the casing or the bracket. The springs elastically support the vibration unit to allow the vibration unit to vibrate in the horizontal direction.

A linear type vibration motor having a magnet casing is disclosed. The linear type vibration motor in accordance with an embodiment of the present invention includes a magnet assembly having a pair of magnets, in which same magnetic poles thereof face each other, a magnet casing, which has a hollow part formed therein and houses the magnet assembly in the hollow part, a base, which has a bobbin formed thereon and in which the magnet casing is inserted into the bobbin, a coil, which is coupled to the bobbin, a weight, which is coupled to both ends of the magnet casing, and a pair of elastic bodies, which are interposed between either end of the base and either end of the weight, respectively. Thus, the operating lifetime of the linear type vibration motor can be extended, and this arrangement can prevent the linear type vibration motor from being damaged by an external shock.

Disclosed herein is a linear vibrator having a mass body which is accommodated in a casing defining an internal space and is vibrated. The linear vibrator includes a bracket supporting the linear vibrator from a lower position. The bracket has a depression in a bottom thereof such that a coil lead wire of a coil is placed in the depression, thus preventing friction between the coil lead wire and a movable unit.

A vibration motor is disclosed. In accordance with an embodiment of the present invention, the vibration motor includes a base, a vibrator, which reciprocates in the base, a protruding part, which is formed on at least one of the base and the vibrator, and an elastic body, which is interposed between the base and the vibrator and has a through-part formed therein and in which the protruding part is inserted into the through-part and the elastic body is coupled to the base or the vibrator by caulking or bending the protruding part which is protruded through the through-part. Thus, the vibration motor can have a uniform resonant frequency characteristic since a spring is coupled by way of caulking or bending.
