Structure for supporting a vibrating system of a loudspeaker.

摘要

A loudspeaker has a yoke base (11a), a center pole (10) formed on the yoke base (11a), an annular magnet mounted (13) on the yoke base (11a), and an annular plate (14) mounted on the magnet (13) so as to form a gap (G) between an inside wall thereof and an outer wall of the center pole (10). A cap (20) made of resin and having a cylindrical portion (20a) is securely mounted on the top of the center pole (10). The cylindrical portion (20a) is disposed in the gap (G). A plurality of projections (21) is formed on the cylindrical portion (20a), each of which extends axially. A voice coil bobbin (16) is disposed between the projections (21) and the inside wall of the annular plate (14).
