Linear type vibration motor having magnet casing
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.
