Title:
MOVING-COIL LINEAR VIBRATING MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/165693
Kind Code:
A1
Abstract:
The present invention provides a moving-coil linear vibrating motor. The motor comprises: a housing having a receiving space; two elastic parts being provided and oppositely connected to a side wall of the housing; a mass block respectively connected to the two elastic parts by a peripheral wall and hung in the receiving space of the housing; two coils being provided and respectively fixedly connected to two ends of the mass block, and the coils forming acute angles or obtuse angles with the central connecting line of the two elastic parts; and two magnets being provided and respectively fixed to the housing at intervals with the corresponding coils, and the magnets forming acute angles or obtuse angles with the central connecting line of the two elastic parts. The present invention enables a Lorentz force that the coils bear to be divided into a component force along a first direction of the central connecting line of the two elastic parts, and a component force along a second direction perpendicular to the central connecting line of the two elastic parts; and the magnets correspondingly bear two acting forces having equal size and opposite directions from the two component forces of the Lorentz force borne by the coils, so that a vibrator assembly including the coils and the mass block may vibrate in two directions perpendicular to each other.
