Vibration generator

The utility model relates to a vibration generator. The vibration generator is installed on a mobile phone, a PDA, a portable game machine and the like, thus generating vibration. The vibration generator transmits signals to users through touch. More specifically, the vibration generator related to by the utility model is as follows: an oscillator is constructed to be fixedly combined with one end portion of an elastomer so as to be able to move in up-and-down, left-to-right and back-and-forth directions, and the resonance frequencies in the up-and-down, left-to-right and back-and-forth directions are respectively different. Under the condition that the frequency of electric signals applied to a coil is consistent with the inherent frequency of the oscillator in any one direction from the up-and-down, left-to-right and back-and-forth directions, the oscillator vibrates towards a motion direction corresponding to the consistent inherent frequency, so that the disadvantages of a conventional rotary type vibration generator and a latest vibration generator vibrating in a single direction are improved, the structure is simple, and various touch modes can be provided for users.
