英文摘要：

This paper designed of a permanent magnet linear vibration generator and explored its output characteristics. According to the structure and working principle of the vibration generator, using the simulation software simulated the out-put voltage of generator in sinusoidal excitation. The prototype was tested for experimental research, and analyzed the output voltage and output power in different coil combinations. Under the sinusoidal excitation with frequency 16 Hz and amplitude 2 mm, the generator＇s output voltage is 9. 153 4 V, and maximum output power is 0. 523 7 W when all the coil in series; the generator＇s output voltage is 4.207 6 V, and maximum output power is 0. 442 6 W when the coil in series and in parallel; the generator＇s output voltage is 0. 823 V, and maximum output power is 0. 338 7 W when all the coil in parallel. In contrast with the experimental result and simulation result, we can conclude that the simulation results were agreed with the experiment results.
