Abstract

The invention discloses a linear vibration motor, which comprises a motor shell, a coil, a vibrator and elastic elements used for suspending the vibrator in the motor shell and providing elastic restoring force for the vibrator. The linear vibration motor is characterized in that the elastic elements comprise elastic supporting pieces arranged at the two ends of a vibration direction of the vibrator, and the two ends of each elastic supporting piece are connected to the vibrator and the motor shell respectively; the elastic supporting pieces are planar elastic pieces; each planar elastic piececomprises an inner plane, an outer plane and elastic arms, wherein the inner plane is arranged in the middle and is connected to the vibrator, the outer plane is arranged on the periphery and is connected to the motor shell, and the elastic arms are used for connecting the inner plane and the outer plane and providing the elastic restoring force for the planar elastic piece. According to the embodiments of the invention, the elastic elements are designed to be the planes, so that the inner planes are connected to the vibrator, and the outer planes are connected to the motor shell, and thus the elastic force provided by the elastic elements is located on a center line of the vibrator movement, the component force and the torque in other directions can be reduced, the vibration is more balanced, and the noise of the motor is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to the technical field of a linear vibration motor. Background technique [0002] Linear vibration motors are commonly known as linear motors. At present, the two ends of the vibrator of the linear motor on the market are respectively provided with an elastic component clamped to the housing, and the elastic component supports the vibrator and provides elastic recovery force for the vibrator. The elastic component in the prior art is usually composed of an elastic arm with a bent structure. The shape of the elastic arm is generally V-shaped, C-shaped, U-shaped and other three-dimensional shrapnel. Because the connection of the shrapnel is not on the center line of the vibrator movement, it will Under a certain torque, there will be no small acceleration in other axial directions other than the vibration direction. This makes the vibration unbalanced, makes the linear motor noisy, a...
