Title (EN) ELECTROACOUSTIC TRANSDUCER
(FR) TRANSDUCTEUR ÉLECTROACOUSTIQUE
(JA) 電気音響変換器
Abstract: front page image
(EN)Provided is an electroacoustic transducer equipped with: an oscillating device (10) which outputs acoustic waves (30) from a first vibratile surface, and which outputs acoustic waves (32) of an opposite phase of the acoustic waves (30) from a second vibratile surface on the reverse surface from the first vibratile surface; a waveguide (40) which is provided upon the first vibratile surface and which has an open end (46); a waveguide (50) which is provided upon the second vibratile surface and which has an open end (56) facing the same direction as the open end (46); and an acoustic wave filter (80) provided upon the waveguide (50) for attenuating the acoustic waves (32).
(FR)L'invention porte sur un transducteur électroacoustique, qui comporte : un dispositif oscillant (10) qui délivre en sortie des ondes acoustiques (30) à partir d'une première surface vibratile, et qui délivre en sortie des ondes acoustiques (32) ayant une phase opposée à celle des ondes acoustiques (30) à partir d'une seconde surface vibratile sur la surface inverse vis-à-vis de la première surface vibratile ; un guide d'ondes (40) qui est disposé sur la première surface vibratile et qui a une extrémité ouverte (46) ; un guide d'ondes (50) qui est disposé sur la seconde surface vibratile et qui a une extrémité ouverte (56) dirigée dans la même direction que l'extrémité ouverte (46) ; et un filtre d'ondes acoustiques (80) disposé sur le guide d'ondes (50) pour atténuer les ondes acoustiques (32).
(JA) 第1の振動面から音波(30)を出力し、第1の振動面とは逆の第2の振動面から音波(30)とは逆位相の音波(32)を出力する発振装置(10)と、第1の振動面に設けられ、開口端(46)を有する導波路(40)と、第2の振動面に設けられ、開口端(46)と同一の方向を向いた開口端(56)を有する導波路(50)と、導波路(50)に設けられた、音波(32)を減衰する音波フィルタ(80)と、を備える電気音響変換器を提供する。
