Abstract

PURPOSE:To enable to reproduce low sound requiring especially large amplitude by giving a driving force according to a sound signal perpendicularly to the surface of a vibrating plate and giving a driving force with a frequency twice as high as that of the sound at a right angle to the former on converting an electric signal to sound.
