Abstract
The invention relates to a vibration generator which is used in devices, such as mobile phones, requiring a vibration mode. More specifically, the invention relates to a horizontal vibration type vibration generator which includes a casing that is open on one surface thereof, a vibration part having a weight provided inside the casing, and a spring mounted inside the casing, and which produces horizontal vibration by using the phenomenon of resonance which occurs by causing oscillation in an electromagnetic force having the same frequency as the intrinsic vibration frequency of the spring, and which solves the problem of a reduction in the life span of the vibration generator due to mechanical friction as seen in existing mechanical vibration generators, and generates a large vibration force despite having a thin construction unachievable in a vertical moving type vibration generator. The invention also relates to a production method of the vibration generator.
