Title (EN) DIAPHRAGM FOR AN ELECTROACOUSTIC TRANSDUCER, AND ELECTROACOUSTIC TRANSDUCER
(FR) MEMBRANE DE TRANSDUCTEUR ELECTROACOUSTIQUE ET TRANSDUCTEUR ELECTROACOUSTIQUE
Abstract:
(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).
(FR) L'invention porte sur une membrane de transducteur électroacoustique de préférence essentiellement rectangulaire et présentant une zone intérieure (20) de conversion du son, une zone extérieure (21) permettant sa fixation, et une zone intermédiaire (22) située entre les zones (20) et (21). La zone (20) est délimitée vers l'extérieur par des côtés de préférence rectilinéaires (23, 24, 25, 26) et la zone (21) est également délimitée vers l'intérieur par des côtés de préférence rectilinéaires (31, 32, 33, 34). Les côtés (23, 24, 25, 26) de la zone (20) sont reliés aux zones cornières arrondies intérieures (27, 28, 29, 30) par un rayon extérieur moyen R, et les cotés (31, 32, 33, 34) de la zone (21) sont reliés aux zones cornières arrondies intérieures (35, 36, 37, 38) par un rayon intérieur moyen r, le rayon r de chacune des zones cornières intérieures (35, 36, 37, 38) étant inférieur à celui du rayon extérieur moyen R de la zone cornière extérieure opposée (27, 28, 29, 30).
