According to the present invention, a linear actuator includes a case which has a space inside, an upper side which is partially closed, and a lower side which is opened, a permanent magnet which is arranged in the case, a movement part which includes a weight which is combined with the permanent magnet, an elastic member whose one side is fixed in the case and the other side is connected to the movement part, a coil which partially surrounds the movement part and is arranged on a part of the inner side of the case, a power supply unit which is connected to the coil, and a bracket which is combined with the power supply unit. Provided is the linear actuator which is used in a wide frequency range by generating a large vibration force by increasing an area of the coil and minimizing an empty space which is not used by arranging the coil outside. |
