Abstract

The invention discloses a linear vibration motor. The motor comprises: a housing; a rotor positioned in the housing, wherein the rotor includes a magnet and a carrier that is used for carrying the magnet and can move in a linear and reciprocating manner; and a coil that sleeves the rotor. The motor further comprises: an elastic member that is arranged on the rotor and is connected with the rotor, wherein the two ends of the elastic member are each provided with an elasticity back bending portion; and two strong magnetic assemblies which are positioned at the sides of the rotor respectively and connected with the housing, wherein the two elasticity back bending portions are abutted against the two strong magnetic assemblies respectively, and the magnet and the strong magnetic assemblies are identical in magnetism. Both elastic force and magnetic expulsive force exist between the rotor and the strong magnetic assemblies, so the rotor still can form strong vibration with the effect of the two types of force even if the performance of the elastic member is poor. Requirements of the performance of the elastic member are reduced, the production efficiency is improved, and high vibration is exhibited.

Description

technical field [0001] The invention relates to the technical field of vibration of electronic equipment, and more specifically, relates to a linear vibration motor. Background technique [0002] Linear vibration motors have a vibration function and can be applied to mobile devices such as mobile phones, tablet computers, electronic watches, and bracelets. The linear vibrating motor currently on the market generally includes a mover and elastic members located at both ends of the mover. When the mover is forced to move linearly, due to the elastic force of the elastic parts at both ends, the mover will move back and forth linearly, thus forming vibration. In order to obtain a strong vibration feeling, in the process of manufacturing the linear vibration motor, the performance index of the elastic parts is extremely high, which increases the processing difficulty of the elastic parts and reduces the production efficiency. [0003] Therefore, how to reduce the processing dif...
