Abstract
Disclosed is a linear vibration motor including a housing, a vibrator assembly, and a driving assembly. The housing is provided with a circuit board. The vibration assembly is disposed in the housing. A through hole is defined in the vibration assembly along the thickness of the housing. The driving assembly is disposed in the through hole and fixedly connected to the housing. The driving assembly includes an iron core and a coil. The iron core includes an intermediate shaft extending along the length of the housing and two end blocks disposed at two ends of the intermediate shaft. The cross-sectional area of the intermediate shaft is smaller than the cross-sectional area of each of the two end blocks. The coil is sleeved on the intermediate shaft and connected to the circuit board. An external circuit is operative to transmit a driving current signal to the coil through the circuit board, so that the driving assembly can drive the vibrator assembly to perform a reciprocating motion along the length of the housing.
