Abstract

320,515. Corell, A. H. H. Oct. 2, 1928. Loud-speakers. - A moving- coil loud-speaker has a conical or push-conical diaphragm provided with a horn c on the concave side, the inner end of the horn having the same shape and size as the outer periphery of the diaphragm. The joint between the horn and diaphragm is preferably airtight and the area of cross-section of the horn may increase towards the flared mouth c<3> while the walls may decrease in thickness in the same direction, and may be plane surfaces.
