A linear vibration motor comprising an oscillator and a stator arranged parallel to the oscillator. The oscillator comprises a counterweight (3) and a vibrating block embeddedly fixed in the counterweight (3). The vibrating block comprises at least two permanent magnets. The stator comprises a coil (51). A conductive magnetic core (52) is arranged in the coil (51). The adjacent end surfaces of the at least two adjacent permanent magnets form slopes (411, 412, 421, 422, 431, and 432) parallel to each other. The slopes (411, 412, 421, 422, 431, and 432) form an acute angle with the axis of the conductive magnetic core (52). The slopes (411, 412, 421, 422, 431, and 432) extend obliquely in the direction approaching the corresponding conductive magnetic core (52). The motor not only ensures the maximization of the sizes of the permanent magnets, but also increases the effective magnetic field intensity between a gap between the adjacent permanent magnets and the conductive magnetic core, thus increasing a driving force driving the oscillator into vibration. |
