Zusammenfassung:To provide an electro-acoustic driver that facilitates fabricating an acoustic diaphragm and surrounding suspension at one end of a bobbin and housing even if the size of an earbud decreases.SOLUTION: A bobbin for an electro-acoustic driver includes an outer surface, a substantially planar surface at an end of the bobbin, and a bobbin axis that is substantially coaxial with a housing axis. The bobbin is usable inside a housing and configured to move along the bobbin axis. The substantially planar surface at the end of the bobbin is securable to an acoustic diaphragm. The bobbin includes one or more of (a) legs extending from the outer surface to the substantially planar surface, (b) a wall which extends across substantially the whole circumference of the planar surface, and (c) a plurality of through holes in the substantially planar surface.SELECTED DRAWING: Figure 6A 【課題】イヤホンのサイズが小さくなってもボビン及びハウジングの一端部において音響振動板及び周囲のサスペンションを製作することが容易な電気音響ドライバを提供する。【解決手段】電気音響ドライバ用のボビンは、外側表面、ボビンの端部の実質的に平坦な表面、及びハウジング軸と実質的に同軸のボビン軸を含む。ボビンは、ハウジングの内部で使用可能であり、ボビン軸に沿って移動するよう構成されている。ボビンの端部の実質的に平坦な表面は、音響振動板に固定可能である。ボビンは、(a)外側表面から実質的に平坦な表面に延びる脚部、(b)平坦な表面の実質的に外周部のすべてにわたって延びる壁、及び(c)実質的に平坦な表面の複数の貫通孔のうちの1つ以上を含む。【選択図】図6A
