Preferably, described vibrational system comprises the bullet ripple, and the centre bore that plays ripple engages with the small-bore port and the voice coil loudspeaker voice coil of support cone.
Preferably, described magnetic circuit system comprises the magnet of T iron and hollow, and T iron is embedded in the magnet, and coaxial with magnet, and the termination of T iron engages with the bottom surface of magnet; Described voice coil loudspeaker voice coil skewer is gone on the T iron.
Preferably, described auxiliary system comprises support, and described support cone is positioned at internal stent, and the heavy caliber port of support cone engages with the inner rim of the top ports of support; Described magnetic circuit system comprises the washer sheet, and its end face engages with support, and the bottom surface engages with magnet, and T iron, magnet and washer sheet are coaxial.
Preferably, described auxiliary system comprises antimagnetic lid and pad, and antimagnetic lid engages with magnet and T iron, and pad is arranged on the inner rim of cantilever tip mouth, and is positioned at the top of inner rim junction of the top ports of the heavy caliber port of support cone and support.
The utlity model has following advantage:
At first, homophase coaxial loudspeaker described in the utility model, the shared voice coil loudspeaker voice coil of its tweeters diaphragms and middle bass vibrating diaphragm has been realized with one heart synchronously, so there is not the phase difference problem, does not also have the modulation shape problem of mixing;
Secondly, during vibration, tweeters diaphragms is sent out the high pitch part, and middle bass part then passes to middle bass vibrating diaphragm and sounding by support cone, thereby has solved the mixed interference problem of scurrying of alt;
Once more, trough and cut apart vibration in the improvement on the one hand, adopts support cone, makes it to be difficult for to resonate, strengthened the cone rigidity with the awl edge; On the other hand, suppress to cut apart vibration and need rigidity and the big cone of internal losses, the rigidity solid has improved the stiff problem of support cone well, the ingenious change of the shape of middle bass vibrating diaphragm, and stick on the support cone, its internal losses obviously cone than single is big.
At last, owing to adopt a voice coil loudspeaker voice coil, reduced the making flow process, its manufacturing cost is lower than similar coaxial loudspeaker.
