摘要:
The present disclosure provides a linear vibration motor, including a casing with an accommodation space, a vibration unit accommodated in the accommodation space, a vibration unit suspended in the accommodation space and a coil fixed on the casing and driving the vibration unit to vibrate. The casing includes a copper ring arranged around the vibration unit. In the linear vibration motor provided by the utility model, the copper ring is arranged around the vibration unit to provide a damping function for the linear vibration motor. Compared with the foam damping member in the related art, the linear vibration motor provided by the present disclosure may be arranged by an automatic device during the production and manufacture of the linear vibration motor, thereby greatly improving the production efficiency, and improving the automation degree.
