The Kyle Condenser Loud Speaker

By using the Kyle principle of construction, it has been possible to develop a practicable condenser loud speaker. The Kyle construction uses a flexible dielectric diaphragm in contact with the high points of a rigid, undulated metal plate. The electrodes of the condenser are the rigid plate and a flexible metal layer attached to the opposite surface of the dielectric. A comparatively large actuating force is thereby obtained and at the same time sufficient amplitude of motion is permitted to give efficient and faithful reproduction.
