PURPOSE: A vibrator using a permanent magnet is provided to simplify a structure by generating the attraction and the repulsion from a core operated as an electromagnet to move a permanent magnet. CONSTITUTION: A vibrator using a permanent magnet includes a core(22), a vibration unit(26), and a plurality of elastic body supporters(25,27). The core(22) is used for generating the magnetic field according to an electric signal applied from the outside and vibrating the vibration unit by using the attraction and the repulsion due to the magnetic field. The vibration unit(26) is vibrated according to the attraction and the repulsion. The elastic body supporters(25,27) are located at the inside of the core to move freely the vibration unit. The vibration unit is formed with a circular bar-shaped permanent magnet.
