となる。(Operation) By inserting the eyelet having the above-mentioned configuration into the insertion hole of the speaker diaphragm and caulking, the metal eyelet protruding below the insulating eyelet is located outside the washer of the insulating eyelet, and the insulating eyelet is removed. Since it acts as a wrapping, it increases the mechanical strength of the eyelet and also has good weldability for soldering. Also, since the ceramic insulating eyelet covers the speaker diaphragm, there is no heat conduction and soldering work becomes easy, resulting in poor soldering. It is possible to improve the rate and prevent loosening of eyelets.
