A formula of induced electromotive force of leaner vibration generators was presented. Linear permanent magnet vibration generator equipped with the new Halbach arrays was designed, two sets of permanent magnets were fixed on two sides of the body, and the inner six coils were connected in series. Compared with those using the conventional Halbach array and traditional permanent magnets, finite element analysis used, the application of the new Halbach array greatly improves the generators’ performance. The maximum output power was 355.85 W, and the open circuit effective voltage was 6.402 9 V, with the sinusoidal vibration frequency was 10 Hz, and the amplitude was 3 mm. At last, the coils’ relative positioning to magnets was optimized, the maximum output power was up to 414.81 mW, 16.57% improved, and the open circuit effective voltage was 7.036 6 V.
