Abstract

The invention provides a vibrating device, comprising: a vibrating assembly, including a counterweight, a first magnet group and an elastic member, the first magnet group is fixed on the counterweight, and the vibrating assembly is suspended in the vibrating device through the elastic member The stator assembly includes a coil and a second magnet group, and the second magnet group is installed in the winding hole of the coil; the first magnet group includes at least two side magnets, and the magnetization direction of the two side magnets is perpendicular to the place where the coil is located. plane; the two side magnets are reversely magnetized; the magnetization direction of the second magnet group is parallel to the plane where the coil is located, and the two poles of the second magnet group are respectively connected to the two side magnets The magnetic poles near the coil attract each other; the vibration assembly is configured to vibrate relative to the stator assembly. The attractive force generated by the second magnet group to the first magnet group can form a centering effect on the vibrating component, and shorten the inertial vibration time of the vibrating component.

Description

technical field [0001] The present invention relates to the technical field of micro-vibration, and more specifically, the present invention relates to a vibration device. Background technique [0002] Vibration motors are mostly used in portable electronic products, such as mobile phones, handheld game consoles and handheld multimedia entertainment equipment. The vibration motor usually includes a housing, a stator and a vibrator. The stator includes a coil fixed on the housing. The vibrator includes a permanent magnet corresponding to the coil and a mass block fixed with the permanent magnet. The vibrator is suspended on the housing through an elastic support. in vivo. [0003] The X-direction vibration motor is a linear vibration motor in which the vibrator vibrates in the X direction. The existing X-direction vibration motors have poor centering effect of the vibrator during the vibration process, and are prone to excessive offset vibration under the action of external...
