Abstract
The present invention is capable of increasing the thinness of a linear vibration motor equipped with a fixed shaft. The linear vibration motor is equipped with: a frame; one fixed shaft extending in one axial direction and affixed to the frame; a drive unit for driving a magnet in the one axial direction, and equipped with a coil affixed to the frame and the magnet, which is positioned so as to be parallel to the fixed shaft; a needle which is slidably supported in the one direction by the fixed shaft, and is equipped with the magnet and a spindle part connected to the magnet; and an elastic member for imparting an elastic force to the needle in opposition to the driving force of the drive unit, and positioned so as not to be coaxial with the fixed shaft.
