Title: (EN) Diaphragm for an electroacoustic transducer, and electroacoustic transducer
(ZH) 用于电声换能器的隔膜和电声换能器
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).
(ZH)

一种用于电声换能器的隔膜(6)被优选的设计成基本上是矩形的,并且具有用于声音转换的隔膜内区(20)和用于连接隔膜(6)的隔膜外区(21)及位于所述隔膜内区(20)和隔膜外区(21)之间的隔膜中间区,其中所述隔膜内区(20)优选的通过直线性的侧面(23,24,25,26)被朝向外侧划界并且所述隔膜外区(21)优选的通过直线性的侧面(31,32,33,34)被朝向内侧划界,其中所述隔膜内区(20)的上述侧面(23,24,25,26)与具有平均外半径值R的圆形外角区(27,28,29,30)相连,而所述隔膜外区(21)的上述侧面(31,32,33,34)与具有平均内半径值r的圆形内角区(35,36,37,38)相连,其中每个内角区(35、36、37、38)的平均内半径值r小于相对外角区(27、28、29、30)的平均外半径值R。
