Abstract
The present disclosure discloses a linear motor including a housing with an accommodation space, a vibrator, a stator, an elastic member and a flexible printed circuit board; the vibrator includes an iron core with an axis direction, a coil wounded around the iron core and a fixing member fixed on the iron core; the flexible printed circuit board is fixed on the fixing member. The fixing member serves as a bridge between the coil and the flexible printed circuit board, thus improving the fixation stability between the coil and the flexible printed circuit board and effectively avoiding disconnection of the coil.
