Abstract

The invention provides a vibration motor, which comprises a base, a vibration unit, an elastic member and a coil assembly, wherein the vibration unit comprises a mass block and magnetic steel; the vibration unit comprises the mass block supported on the elastic element and the magnetic steel fixed on the mass block and arranged opposite to the coil assembly; the magnetization direction of the magnetic steel is a thickness direction; a drive signal is applied to the coil assembly; the elastic member supports vibration of the vibration unit along the direction vertical to the magnetization direction; and the vibration unit vibrates along any one of a first vibration direction vertical to the magnetization direction, a second vibration direction vertical to the magnetization direction and vertical to the first vibration direction and a third direction in a plane in which the first vibration direction and the second vibration direction are located through adjusting the drive signal. Compared with the related technology, the vibration motor provided by the invention has the advantages that multidirectional vibration is achieved and the vibration effect is good.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of motors, in particular to a vibration motor used in portable consumer electronic products. [0003] 【Background technique】 [0004] 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., generally use vibration motors for system feedback, such as mobile phone Incoming call prompts, information prompts, navigation prompts, vibration feedback of game consoles, etc. Such a wide range of applications requires high performance, good stability and long service life of the vibration motor. [0005] A linear vibration motor in the related art includes a base with a storage space, a vibration unit located in the storage space, an elastic member for fixing and suspending the vibration unit in the storage space, and a coil fixed to the...
