LOUDSPEAKER HAVING SUSPENSION MEMBER IN WHICH DIAPHRAGM OF LOUDSPEAKER DRIVER IS ATTACHED TO CHASSIS OF LOUDSPEAKER DRIVER, DRIVER, AND DRIVER

摘要

PROBLEM TO BE SOLVED: To provide a loudspeaker driver in which a high level distortion caused by a non-liner rigidity normally occurred in a driver using a progressive suspension member.;SOLUTION: A suspension member 100 in which a diaphragm of a loudspeaker driver is attached to a chassis of the loudspeaker driver, includes a geometric shape including: two opposite liner sections 130; and two opposite curvature sections 110 connecting the two liner sections 130. The two opposite curvature sections 110 include a curvature radius smaller than that of the liner sections 130. An average height of a radial direction cross sectional outer form of the curvature sections 110 is higher than that of the liner sections 130. The liner sections 130 includes an axial direction rigidity higher than the curvature sections 110.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
