Beschreibung
Zusammenfassung:The invention provides a moving-coil linear vibrating motor, comprising: a housing having a receiving space; two elastic parts oppositely connected to the sidewall of the housing; a weight connected with the two elastic parts through its peripheral wall and hung in the receiving space of the housing; two coils fixedly connected to the two ends of the weight respectively, center lines of the coilsand elastic parts form acute angles or obtuse angle; two magnets, wherein the magnets and the corresponding coils are fixed to the housing at intervals, and center lines of the magnets and the elasticparts form acute angles or obtuse angles. Lorentz force that the coils bear can be divided into component force along a first direction of the center line of the two elastic parts, and component force perpendicular along a second direction perpendicular to the center line of the two elastic parts, the magnets correspondingly bear two acting forces equal to the two component forces of the Lorentzforce borne by the coils in
