Abstract

New loudspeakers with honeycomb disc diaphragm have low distortion, wide frequency range, and uniform frequency response characteristics. These characteristics are realized by using the diaphragm with one of the highest rigidity due to gradient of density and equivalent Young's modulus by varying the cell size of the honeycomb core in the direction of radius, and by driving the diaphragm at the position of first nodal circle for eliminating low-order break-up vibrations.
