摘要:
The present invention makes thinness or widthwise compactness possible, while exhibiting the advantages of obtaining stable vibrations and excellent impact strength, just as in a linear vibration motor equipped with a fixed shaft. A linear vibration motor equipped with: a needle equipped with a magnet and a spindle part; a frame for slidably supporting the needle in one axial direction; a coil for driving the magnet in the one axial direction, and affixed to the frame; and an elastic member for imparting an elastic force to the needle in opposition to the driving force imparted on the magnet. Therein, the needle is equipped with a pair of shaft parts which project in opposite directions in the one axial direction, and the frame is equipped with bearings for slidably supporting the pair of shaft parts.
