The loudspeaker is the directly radiated speaker which generates the sound by the vibration of cone paper. Therefore the shape and the vibration characteristics of th cone paper is important factors affecting the performance of speaker. The vibration mode of cone paper is piston mode that vibrates to the up-down direction, and we can see the divided vibration in the higher mode. Because the loudspeaker has a damper, the vibration mode is different to the mode of the only cone paper. In this study, the vibration mode of cone paper which considering the damper and the effects of the damper diameter were investigated by finite element method.
