Title: (EN) Diaphragm for an electroacoustic transducer, and electroacoustic transducer
Abstract: front page image
(EN)

A diaphragm (6) for an electroacoustic transducer is preferably designed to be essentially rectangular and has a diaphragm inner region (20) for sound conversion and a diaphragm outer region (21) for attaching the diaphragm (6) and a diaphragm intermediate region (22) which lies between the diaphragm inner region (20) and the diaphragm outer region (21), wherein the diaphragm inner region (20) is delimited toward the outside by preferably rectilinear sides (23, 24, 25, 26) and the diaphragm outer region (21) is delimited toward the inside again by preferably rectilinear sides (31, 32, 33, 34), and wherein the aforementioned sides (23, 24, 25, 26) of the diaphragm inner region (20) are joined to rounded outer corner regions (27, 28, 29, 30) with a mean outer radius value R and the aforementioned sides (31, 32, 33, 34) of the diaphragm outer region (21) are joined to rounded inner corner regions (35, 36, 37, 38) with a mean inner radius value r, wherein the mean inner radius value r of each inner corner region (35, 36, 37, 38) is smaller than the mean outer radius value R of the opposite outer corner region (27, 28, 29, 30).
