Abstract:
A linear vibration motor (100), comprising a housing (110) having an accommodation space (116), a vibrator (150) accommodated in the accommodation space (116) and capable of vibrating, and elastic elements (140) arranged on two sides of the vibrator (150). Swinging members (1126) capable of swinging are arranged on two sides of the housing (110), a swinging direction of the swinging member (1126) is consistent with a vibration direction of the vibrator (150), one end of the elastic element (140) is fixedly connected to the vibrator (150), and the other end of the elastic element (140) is fixedly connected to the swinging member (1126). In the linear vibration motor (100), the elastic elements (140) are connected to the vibrator (150), and then the swinging members (1126) on the housing (110) are connected to the elastic elements (140). When the vibrator (150) vibrates, the elastic elements (140) can be driven to vibrate, and the elastic elements (140) drive the swinging members (1126) to vibrate. In this way, both the swinging members (1126) and the elastic elements (140) can provide a vibration stroke for the vibrator (150), thereby improving the vibration intensity of the vibrator (150).
