PURPOSE: A horizontal linear vibrator is provided to maximize electromagnetic efficiency by symmetrically arranging a magnet around the center of a coil. CONSTITUTION: A case has an inner space. A coil(125) is arranged in the inner space of the case. A mass(121) is moved by an electromagnetic force between a permanent magnet(113) and a coil. A power connection unit(115) supplies power to the coil. A spring(123) is arranged between a moving unit and the case. |
