帯状音響放射体III : 扁平回転楕円体帯状音響放射体

抄録

A series of analysis for the zonal sound radiator has been performed. As the last part of these research, the analysis for the zonal vibration of an oblate spheroid has been developed in this paper. The directivity of radiated sound pressure and power, and the radiation impedance have been calculated. Four previous results, i. e. the data on cylinder, prolate spheroid, sphere, and oblate spheroid, were compared with each other. These data may be usefull for the design of the wide frequency range mushroom sound radiator.
