METHOD FOR MANUFACTURING MAGNETIC CIRCUIT PORTION OF DYNAMIC SPEAKER

摘要

PURPOSE: A method for manufacturing a magnetic circuit portion of a dynamic speaker is provided to reduce the prices of manufacturing a speaker by improving the productivity of the speaker with simplifying the progress of manufacturing of a magnetic circuit portion. CONSTITUTION: A method for manufacturing a magnetic circuit portion of a dynamic speaker a few progresses. In the first progress an inserting central axis is formed on the center of an ejected formed frame(10). In the second progress a york(20) with a hole(20'), a magnet(30) and a top plate are layed on the inserting central axis in order. In the third progress the contacting faces of each part is sticked by a glue in order to prevent that the parts are out of order and the upper part of the inserting central axis is compressed by heat.
