| Abstract(in English) | A theoretical analysis for the vibration transmission characteristics of conically shaped spike are derived to clarify how the vertical angle of conical shape and property of material influent its characteristics. Based on its result, the vertical angle of conical shape and the property of material have an effect on cutoff frequency of vibration transmission and the transmission factor from vertex to base is reduced than that in inverse use for same cross section. Results of hearing test on sound quality and summing localization for test pieces made by nylon 6 and polycarbonate for stereophonic equipments showed effectiveness to improve the reproduced stereophonic sound. |
