Abstract

The invention provides a vibration device which comprises a shell, a vibrator assembly and a stator assembly, the vibrator assembly and the stator assembly are contained in the shell, the stator assembly comprises a coil assembly fixedly connected with the shell, and the vibrator assembly is suspended in the shell through an elastic supporting piece; the vibrator assembly comprises a magnetic steel assembly, the magnetic steel assembly comprises driving magnetic steel, and the magnetizing direction of the driving magnetic steel is parallel to the vibration direction of the vibrator assembly; the vibration device further comprises a damping copper block, the damping copper block is fixed to the shell, and the damping copper block and the driving magnetic steel are oppositely arranged. The vibration device has a good electromagnetic damping effect, so that the system can respond quickly, the braking time is short, and a user can obtain better experience.

Description

technical field [0001] The invention relates to the technical field of electronic products. More specifically, it relates to a vibration device. Background technique [0002] With the development of communication technology, portable electronic products, such as mobile phones, handheld game consoles or handheld multimedia entertainment devices, have entered people's lives. In these portable electronic products, a vibration device is generally used for system feedback, such as an incoming call notification of a mobile phone, vibration feedback of a game console, and the like. [0003] However, the existing vibration devices generally provide system damping through foam, magnetic fluid, silica gel, etc., but foam, magnetic fluid, silica gel, etc. are prone to failure, resulting in poor system damping stability and difficult to guarantee the performance reliability of the vibration device. Contents of the invention [0004] In view of the above problems, the present inventi...
