Title (EN) DIAPHRAGM AND SPEAKER USING SAME
(FR) DIAPHRAGME ET HAUT-PARLEUR L'UTILISANT
(JA) 振動板とそれを用いたスピーカ
Abstract: front page image
(EN)A first reinforcing rib (14), a second reinforcing rib (16) and a third reinforcing rib (17) are integrally formed on at least the front surface or the rear surface of a diaphragm (10) composed of a synthetic resin. The Strength of a loudspeaker using such diaphragm is improved, the weight of the loudspeaker is reduced and disturbance in smooth output of the sounds is eliminated, by constituting the first reinforcing rib (14) as an assembly of a plurality of hexagons.
(FR)Selon la présente invention, une première (14), une deuxième (16) et une troisième nervure de renforcement (17) font partie intégrante de la surface avant ou de la surface arrière, au moins, d'un diaphragme (10) composé d'une résine synthétique. Le fait de monter la première nervure de renforcement (14) tel un ensemble composé d'une pluralité d'hexagones permet d'accroître la résistance d'un haut-parleur utilisant un tel diaphragme, de réduire le poids du haut-parleur et d'éliminer toute perturbation de la sortie lisse des sons.
(JA) 合成樹脂よりなる振動板(10)の表面と裏面の少なくとも一方に第1の補強リブ(14)、第2の補強リブ(16)、第3の補強リブ(17)を一体に形成し、第1の補強リブ(14)は複数の六角形の集合体とすることにより、この振動板を用いたスピーカの強度向上、軽量化を図り、音声を出力しにくくなるのを防止する。
