摘要： [Summary] voice coil Aku Yu eta (50), magnetic flux conducting material made with a core (54) and the magnet (53) back plate (52, 52 '') (57), and current-conducting coil (56, 56'' I inclusive). I have (60) a continuous groove provided core ''is (58, 58 first surface (52, 52)'', 58 ") and, (58, 58 '', 58 surface of the first") to. Groove (60) has a (62, 64)
wotanopposite walls of the pair. Magnets (54), and is arranged in clo contact with the wall of the first of said walls (62, 64), between the wall and a cond one (54) of the wall (62, 64)magnetic are spaced from the walls of the cond of said walls (62, 64) to such an extent
that a gap remains in the. Magnets (54), a first surface facing the wall with a first of the walls (62, 64), the magnetic polarities of the first and (94), facing the gap, the magnetic cond opposite and a cond surface having a polarity (96). Furthermore, the magnet (54), a bottom groove (60) to a substantially normal to the wall of the cond one walls (62, 64) from (96) the cond surface magnetic flux cross the gap are spaced from (76).
