Lower plate, sealing ring, iron core, aluminium ring and bracket, on same center line, magnetic conduction upper plate and frame are riveted, upper plate, magnet steel, magnetic conduction
Lower plate successively bonds together, and iron core, aluminium ring, bracket are successively bonded to be inserted through sealing ring centre bore and be inserted in iron core and combine
In upper plate, magnetic conduction lower plate centre bore, and make magnetic conduction lower plate, sealing ring, bracket successively bond together voice coil with play after wave combines
Cover on iron core, by play wave it is Nian Jie with frame, under cone stomidium cover outside voice coil and be bonded, upper surface it is Nian Jie with frame；Voice coil
For two windings independent, according to use occasion and condition, in parallel, the modes of connection and the power amplifier such as connect or recommend can be used
Machine connection uses.But it is complex as the double voice coil woofer structure that the markets such as above-mentioned patent provide, it is unfavorable for
Assembling and tuning arrangement.
