SPEAKER SYSTEM

摘要

PURPOSE:To reduce an externally leaking magnetic flux from a cabinet by attaching a steel wool in the inside of a speaker cabinet. CONSTITUTION:An iron made frame 5 having a center pole 3 at the center of a yoke 2 provided in contact with the end surface of the magnetic pole of a magnet 1 and holding an oscillating section in contact with a plate 4 is provided. A voice coil 6 is held in a magnetic gap 7 formed in an annular shape by a center pole 3 and a plate 4. Steel wool 15 is attached to the side surface of a speaker cabinet 14 by the use of a steple or the like. The magnetic flux leaking from the iron made frame 5 to the cabinet 14 side is absorbed by the steel wool and the magnetic flux externally leaking from the cabinet is remarkably reduced.
