Abstract

The invention discloses a linear vibration motor. The linear vibration motor comprises a vibrator assembly, a stator assembly and an elastic element. The vibrator assembly is connected to the stator assembly through the elastic element, the vibrator assembly is subjected to the action of electromagnetic force of the stator assembly and generates vibration, magnets are installed at the two ends ofthe vibration direction of the stator assembly, the magnets are adhesively connected to the stator assembly or connected to the stator assembly in a injection molding mode, the stator assembly is provided with magnetic elements, the magnetic elements corresponds to the magnets one by one, and repulsive force is formed between the magnetic elements and corresponding magnets. The rigidity of the linear vibration motor presents as a non-linear change, and therefore improves vibration sense experience.

Description

technical field [0001] The present invention relates to the technical field of vibration devices, and more particularly, to a linear vibration motor. Background technique [0002] Currently, a linear vibration motor includes a vibrator assembly, a stator assembly, and an elastic element. The stator assembly includes the shell, the coil, the FPCB, the limiting parts and so on. The coil and the FPCB are fixed on the bottom wall or the top wall of the housing. The vibrator assembly is suspended in the housing through the elastic element. The elastic element provides elastic recovery force, for example, the elastic element is a shrapnel. The limiting component is located on the side of the vibrator assembly to damp the vibrator assembly. The vibrator assembly includes a mass block, a magnet assembly, and the like. The magnetic assembly is acted upon by the electromagnetic force of the coil. The vibrator assembly vibrates under the action of the electromagnetic force. [0...
