Abstract

The invention discloses a linear vibration motor, comprising: a fixed portion, a movable portion, and a supporting portion; the fixed portion further comprises an outer frame, a coil set, a conductivesheet set, a connecting circuit and a terminal; the movable portion comprises a bracket, a primary magnet set, at least a secondary magnet set; the supporting portion comprises a pair of elastic members connected to the fixed portion and the movable portion, and provides a restoring force when the movable portion is displaced; the coil set and the primary magnet set provide a driving force to drive the movable portion to generate vibration; the conductive sheet set and the secondary magnet set provide damping when the movable portion moves.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a linear vibration motor. Background technique [0002] Generally, mobile devices and wearable devices must be configured with a vibration motor to provide a vibration function as a tactile feedback when the user operates the device. Among them, the linear vibration motor has become the first choice for configurations such as mobile devices and wearable devices because it can provide a variety of vibration modes. [0003] The linear vibration motor itself usually uses a driving coil of a fixed part to drive a magnet carried by a movable part to generate motion, and uses an elastic device to connect the movable part to the fixed part; in other words, the elastic device supports the movable part. The movable part and provide the restoring force required for the movable part to generate vibration. [0004] However, since the mobile device may be shaken by an external force, the mov...
