The present invention relates to a vibrator which generates vibration by being installed in a mobile phone, a PDA, a portable video game, and transmits a signal to a user through tactile impression. According to the present invention, a vibrator is fixed and combined with one end of an elastic body, and can move up and down, left and right, and forward and backward. The resonance frequency of up and down, left and right, and forward and backward directions is respectively and diversely formed. If the frequency of an electric signal applied to a coil corresponds to the resonance frequency of one direction among up and down, left and right, and forward and backward directions, the vibrator vibrates in a movement direction corresponding to the corresponded resonance frequency. Accordingly, the vibrator has a simple structure, and can provide various tactile impression to the user by supplementing faults of existing rotational vibrators and recent one-direction vibrators.
