| Abstract(in English) | The spatial sound source made by focusing parametric array has two main problems as a speaker. One is the low sound level and the other is the narrow emission angle. The integration of transducers was tried to solve these problems. The transducers were arrayed to make spherical sound wave front. The sound pressure at the focused point is increased by the integration corresponding to the number of transuducer used. The emission angle was also widened by integration and the effects was confirmed by localizing characteristics of sound beam similary made by parmetric array was also examined. |
