Title:
MOVING-MAGNETIC TYPE LINEAR VIBRATION MOTOR
Document Type and Number:
WIPO Patent Application WO/2019/165694
Kind Code:
A1
Abstract:
A moving-magnetic type linear vibration motor, comprising: a housing, provided with an accommodating space (10); elastic elements (2), there being provided with two elastic elements which are oppositely connected to the side walls of the housing; a mass block (3), separately connected to the two elastic elements (2) by means of the peripheral wall and suspended in the accommodating space (10) of the housing; magnets (4), there being provided with two magnets which are fixedly connected to two ends of the mass block (3) respectively, and an acute angle or obtuse angle being formed between the magnets (4) and a center connecting line of the two elastic elements (2); and coils (5), there being provided with two coils which are respectively fixed on the housing with the corresponding magnets (4) at intervals, and an acute angle or obtuse angle being formed between the coils (5) and the center connecting line of the two elastic elements (2). The motor can decompose Lorentz force borne by the coils (5) into component force in a first direction of the center connecting line of the two elastic elements (2), and the component force in a second direction perpendicular to the center connecting line of the two elastic members (2); the magnets (4) are correspondingly subjected to two acting forces equal to and opposite in direction to the two component forces of Lorentz force borne by the coils (5), so that a vibrator assembly comprising the magnets (4) and the mass block (3) can vibrate in two directions perpendicular to each other.
