Problems solved by technology

[0004] However, in the linear vibration motor of the related art, the elastic member is made of a ring-shaped single-layer stainless steel material. The structure has very little mechanical damping, and it is easy to swing on a plane perpendicular to the vibration direction when vibrating, and the vibration fatigue is reliable. Poor performance makes its service life short

Abstract

The invention provides a linear vibration motor. The linear vibration motor comprises a base vibration unit with an accommodating space, an elastic part for suspending the vibration unit in the accommodating space and a coil for driving the vibration unit to vibrate; the elastic part is located on one side of the vibration direction of the vibration unit, and the coil and the vibration unit are opposite to each other and are arranged at intervals; the elastic part comprises a ring-shaped main body defined by elastic arms, a first fixed arm which extends from two opposite elastic arms of the main body and is fixed on the base, a second fixed arm extends from the other two opposite elastic arms of the main body and is fixed to the vibration unit, a reinforcing rib which extends from one of the elastic arms to the other elastic arm which is opposite to the elastic arm and is connected with the elastic arm, and damping parts which are at least attached to the local positions of the elasticarms. Compared with the related art, the linear vibration motor disclosed by the invention is high in vibration performance and long in service life.

Description

technical field [0001] The invention relates to a motor, in particular to a linear vibration motor used in the field of mobile 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. Such a wide range of applications requires excellent performance and long service life of the vibration motor. [0003] The linear vibration motor in the related art includes a base with a storage space, a vibration unit located in the storage space, and a device that is arranged on one side of the vibration unit along the vibration direction and fixes and suspe...
