Title (EN) ELECTROACOUSTIC TRANSDUCER
(FR) TRANSDUCTEUR ÉLECTROACOUSTIQUE
(JA) 電気音響変換器
Abstract:
(EN) An electroacoustic transducer (100) which is provided with: a diaphragm (110); a magnetic circuit (120) which has a magnetic gap (121); a foundation member (130) which holds the diaphragm (110) and the magnetic circuit (120); and a voice coil body (140) which has one end that is arranged within the magnetic gap (121) and the other end that is bonded to the diaphragm (110). This electroacoustic transducer (100) is also provided with a low-friction material (150) which is arranged in a sliding part between the voice coil body (140) and the magnetic circuit (120), and which is composed of a polymer compound that is swollen with a liquid.
(FR) L'invention concerne un transducteur électroacoustique (100) qui est pourvu : d'un diaphragme (110); d'un circuit magnétique (120) qui a un entrefer magnétique (121); d'un élément de fondation (130) qui maintient le diaphragme (110) et le circuit magnétique (120); et un corps de bobine acoustique (140) qui a une extrémité qui est disposée à l'intérieur de l'espace magnétique (121) et l'autre extrémité qui est liée au diaphragme (110). Ce transducteur électroacoustique (100) est également pourvu d'un matériau à faible frottement (150) qui est agencé dans une partie coulissante entre le corps de bobine acoustique (140) et le circuit magnétique (120), et qui est composé d'un composé polymère qui est gonflé avec un liquide.
(JA) 振動板(110)と、磁気ギャップ(121)を有する磁気回路(120)と、振動板(110)と磁気回路(120)とを保持する基礎部材(130)と、一端部が磁気ギャップ(121)内に配置され、他端部が振動板(110)に結合されるボイスコイル体(140)とを備え、ボイスコイル体(140)と磁気回路(120)との摺動部に配置される液体で膨潤された高分子化合物により成る低摩擦材料(150)とを備える電気音響変換器(100)。
