The first diaphragm 211 and the second diaphragm 212 adhere and clamp the magnetic component 210 between the first diaphragm 211 and the second diaphragm 212 to form the diaphragm-shaped combined magnet 200. In the assembly process of this type of diaphragm-shaped combined magnet similar to the above-mentioned diaphragm-shaped combined magnet 200, the first diaphragm 211 (Mylar sheet) and the second diaphragm 212 (Mylar sheet) need to be taken out from the roll material by a roll feeder, and then the Mylar sheet is transferred according to the magnet assembly requirements. During the transfer of the Mylar sheet (diaphragm), the Mylar sheet is not accurately positioned and is easy to fall off, and the assembly efficiency is low.
