Abstract:
(EN) A speaker is provided with a diaphragm having an opening in the center, a voice coil, an edge part, a frame, and a magnetic circuit. The voice coil is attached to the inner periphery of the diaphragm. The edge part is attached to the outer periphery of the diaphragm. The frame supports the diaphragm across the edge part. The magnetic circuit has a magnetic gap, and is arranged on the frame so that the voice coil is positioned inside the magnetic gap. The edge part is configured from a front side edge part and a back side edge part. The inner peripheral section of the front side edge part is secured to the upper surface of the diaphragm, and the outer peripheral section of the front side edge part is secured to the frame. The inner peripheral section of the back side edge part is secured to the lower surface of the diaphragm, and the outer peripheral section of the back side edge part is secured to the frame. The mechanical characteristics of the back side edge part are the same as the mechanical characteristics of the front side edge part.
(FR) L'invention concerne un haut-parleur pourvu d'une membrane présentant une ouverture en son centre, une bobine acoustique, une partie de bord, un cadre et un circuit magnétique. La bobine acoustique est fixée à la périphérie interne de la membrane. La partie de bord est fixée à la périphérie externe de la membrane. Le cadre soutient la membrane sur la partie de bord. Le circuit magnétique présente un espace magnétique, et est disposé sur le cadre de sorte que la bobine acoustique est placée dans l'espace magnétique. La partie de bord est conçue à partir d'une partie de bord latéral avant et d'une partie de bord latéral arrière. La section périphérique interne de la partie de bord latéral avant est fixée à la surface supérieure de la membrane, et la section périphérique externe de la partie de bord latéral avant est fixée au cadre. La section périphérique interne de la partie de bord latéral arrière est solidement fixée à la surface inférieure de la membrane, et la section périphérique externe de la partie de bord latéral arrière est solidement fixée au cadre. Les caractéristiques mécaniques de la partie de bord latéral arrière sont identiques aux caractéristiques mécaniques de la partie de bord latéral avant.
(JA) スピーカは、中心に開口を有する振動板と、ボイスコイルと、エッジ部と、フレームと、磁気回路と、を備えている。ボイスコイルは、振動板の内周に取り付けられる。エッジ部は、振動板の外周に取り付けられる。フレームは、エッジ部を介して振動板を支持する。磁気回路は、磁気ギャップを有し、磁気ギャップ内にボイスコイルが位置するように、フレームに配置される。エッジ部は、表側エッジ部と裏側エッジ部とで構成される。表側エッジ部の内周部が振動板の上面に固定され、表側エッジ部の外周部がフレームに固定される。裏側エッジ部の内周部が振動板の下面に固定され、裏側エッジ部の外周部がフレームに固定される。裏側エッジ部の機械特性は、表側エッジ部の機械特性と同じである。
