발명의 명칭: (EN) SPEAKER-USE DIAPHRAGM AND SPEAKER USING IT AND ITS PRODUCTION DIE
(FR) DIAPHRAGME POUR HAUT-PARLEUR, HAUT-PARLEUR L'UTILISANT ET SA MATRICE DE PRODUCTION
(JA) スピーカ用振動板とこれを用いたスピーカおよびその製造金型
요약서: front page image
(EN)A speaker-use diaphragm produced by paper-making a pulp material and then pressing it partially to reduce its thickness. The speaker diaphragm of this structure is easy to produce, has stable frequency characteristics in medium and high regions, has an improved sound pressure level in a high region, and realizes a good-sound-quality wide-band reproduction. In addition, it can reduce partial resonance caused by a diaphragm.
(FR)La présente invention concerne un diaphragme pour haut-parleur produit en transformant en papier une matière de pulpe puis en la pressant en partie pour réduire son épaisseur. Le diaphragme de haut-parleur de cette structure est facile à produire, a des caractéristiques de fréquence stables dans les régions moyennes et hautes, un niveau de pression sonore amélioré dans la région haute et une bonne reproduction de qualité de son à large bande. Il peut en outre réduire la résonance partielle provoquée par un diaphragme.
(JA) パルプ材料を一度抄紙した後、部分的にプレスして厚みを薄くしたスピーカ用振動板を提供する。この構造のスピーカ振動板は、作り方が簡単な上、中高域での周波数特性が安定し、高域での音圧レベルが向上し、音質の良い広帯域再生を実現する。また、振動板に起因する分割共振を低減させることが可能となる。
