Abstract

The invention provides a linear vibration motor, and the motor comprises a housing with an accommodation space, a coil fixed in the housing, a vibration unit which is oppositely separated from the coil, and an elastic body which enables the vibration unit to be suspended in the accommodation space. The elastic body comprises an elastic part and damping material layers stacked on the elastic part.The damping material layer comprises at least two layers, and the elastic part is clamped between the two damping material layers. The elastic part and the damping material layers are integrated intoone structure. Compared with the prior art, the motor provided by the invention is simple in assembly program, is good in vibration performances, and is quick in response speed.

Description

【Technical field】 [0001] The invention relates to the technical field of motors, in particular to a linear vibration motor applied to portable electronic products. 【Background technique】 [0002] With the development of electronic technology, portable consumer electronic products are becoming more and more popular, such as mobile phones, handheld game consoles, navigation devices or handheld multimedia entertainment equipment, etc. These electronic products generally use linear vibration motors for system feedback , such as mobile phone call prompts, information prompts, navigation prompts, vibration feedback from game consoles, etc. With such a wide range of applications, the performance requirements of linear vibration motors are getting higher and higher. [0003] The linear vibration motor in the related art includes a housing with a housing space, a vibration unit accommodated in the housing space, an elastic member supporting and suspending the vibration unit in the h...
