Abstract
Eine Lautsprechermembran umfasst einen sich verjuengenden Randbereich. Hierdurch ist es moeglich, auf kostenguenstige und wirksame Weise eine Wellen-Reflexion und eine dadurch verursachte unkontrollierte Wellenausbreitung zu verhindern oder deutlich zu reduzieren.

 

WO2006066850 A UPAB: 20060801 NOVELTY - Loudspeaker diaphragm (62) has tapering region (12) which is fitted in such a manner that sound can spread in the form of bending waves into its body whereby airborne sound becomes lively. Tapering boundary region is a wedge-shaped range, which extends with reducing thickness from main body region (10) of the loudspeaker diaphragm to outside edge of loudspeaker diaphragm. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (A) Loudspeaker; and (B) Method for producing loudspeaker diaphragm USE - Loudspeaker diaphragm. ADVANTAGE - Ensures simple and economical solution for the problem of wave reflection and the uncontrolled wave propagation.
