VIBRATION EXCITER FOR ELECTRONIC PRODUCT, AND ELECTRONIC PRODUCT

摘要

A vibration exciter for an electronic product, and an electronic product. The vibration exciter comprises: a first vibration assembly, the first vibration assembly comprising a first shell (101) and a magnetic circuit assembly arranged below the first shell (101); and a second vibration assembly, the second vibration assembly comprising a second shell (105) and at least two sets of coils (102) arranged above the second shell (105). The at least two sets of coils (102) are arranged on two sides of the magnetic circuit assembly; the magnetic circuit assembly comprises a central magnet (103b) and at least two side magnets (103a, 103c) in a vibration direction; the magnetizing directions of the at least two side magnets (103a, 103c) are parallel to the axial direction of the coil (102), and the magnetic pole directions are opposite; the central magnet (103b) comprises at least two sets of magnets (1031b, 1032b) in a direction perpendicular to the vibration direction, the magnetizing directions of the at least two set of magnets (1031b, 1032b) are parallel to the vibration direction, and the magnetic pole directions are opposite. The density of magnetic induction lines generated by the magnetic circuit assembly is more aggregated, more effective magnetic induction lines can penetrate through the coils, and the driving force of the vibration exciter is improved.
