PURPOSE: A linear vibrator having a vibration absorption part is provided to prevent the contact between a mass and a case by interposing a vibration absorber between the mass and the case. CONSTITUTION: In a linear vibrator having a vibration absorption part, a permanent magnet(113), a coil unit, and a circuit board are arranged inside a case. Masses(121a,121b) are vibrated between the coil unit and the permanent magnet through electromagnetic force. A vibration absorber(130) is included between the mass and a case and prevent the contact between the mass and the case. The vibration absorber reduce vibration which is different direction from the movement of the mass. |
