Abstract:
The present disclosure discloses a linear motor including a housing with an accommodation space, a vibrator and a stator received in the accommodation space and an elastic support fixed on the vibrator and configured to suspend the vibrator in the accommodation space; the stator includes a coil and a copper ring both opposite to the vibrator; the copper ring and the coil are arranged on two opposite sides of the vibrator separately along a first direction perpendicular with a vibration direction of the vibrator. The copper ring serves as a damper providing electromagnetic resilience for the vibrator, effectively improve the automation and efficiency of the manufacture of the linear vibration motor.
