Problems solved by technology

However, the resulting overall diaphragm shape has substantial disadvantages in that adjacent parts of the moving diaphragm area are not always generally parallel to each other and their geometry varies between the inner and outer semi-enclosed spaces due to the non- Medial-to-outer moving diaphragm surface nonlinearity for optimal acoustic loading results in substantial sound distortion

Abstract

An air motion transducer loudspeaker driver includes a plurality of diaphragm layers having electrical conductors. Each diaphragm layer defines a surface having at least one curvature. The curved portion has a curvature axis perpendicular to the surface of the diaphragm layer at the position of the curved diaphragm portion.

Description

[0001] related application [0002] This application claims priority to US Provisional Application Serial No. 61 / 688,244, filed May 9, 2012. technical field [0003] The present invention relates generally to a loudspeaker driver, and more particularly to a loudspeaker driver of the Air Motion Transducer type, also commonly known to those skilled in the art as an "AMT" loudspeaker driver. Background technique [0004] In U.S. Patent No. 3,636,278 inventor Oskar Heil describes a number of embodiments of AMT speaker drivers in which audible sound is produced by immersing a thin, flexible, folded diaphragm in a magnetic field in such a way that when When an alternating audio current flows through the conductors inscribed on the folded diaphragm, adjacent portions of the folded diaphragm will move away from each other or toward each other, depending on the relative directions of the currents flowing in the moving parts of each diaphragm . [0005] This movement of the diaphrag...
