Abstract
The present invention provides a linear vibration motor, which includes a base, a vibration unit, an elastic part and a coil assembly. The vibration unit has a weight, a pole plate and a magnet. The coil assembly includes an iron core and a coil fixed to the iron core. Further, the iron core includes an iron core body for being wound by the coil, and an iron core extension part extended and fixed from the opposite ends of the iron core body. The iron core extension part of the base includes a connecting part connected to the iron core body and a fixing part bent and extended by the connecting part and fixed to the base. A thickness of the connecting part is greater than a thickness of the fixing part. Compared with the related technology, the linear vibration motor has improved vibration performance.
