As improvement, described outer ring is convex, and the concave panel of ring is provided with splay reinforcement outside.Ring with reinforcement is enough to support and retrain whole vibrating diaphragm, so just can save centring disk, and this is another key element of ultrathin loudspeaker design.
As improvement, described voice coil loudspeaker voice coil is positioned at described ring below.
As improvement, described magnetic circuit system comprises magnetic conduction sheet, upper magnetic steel, middle magnetic conduction sheet, lower magnetic steel, lower magnetic conduction sheet from top to bottom successively.This magnetic circuit system can reduce the magnetic field loss of energy, and the magnetic field energy that offers voice coil loudspeaker voice coil is larger, helps to increase the amplitude of sound basin.
As improvement, described interior ring is fixed on the described upper magnetic conduction sheet by pad.Because magnetic circuit system can produce heat in work, if being delivered to, heat can make the distortion of sound basin on the sound basin, cause the sounding distortion, the effect of pad is that the heat that magnetic circuit system produces is cut off, and heat can be delivered on the sound basin.
As improvement, described upper magnetic conduction sheet is provided with projection, and corresponding described raised position is provided with shrinkage pool on the described pad, and described projection matches with described shrinkage pool.The projection of upper magnetic conduction sheet cooperates the effect of playing centering with the shrinkage pool of pad, the installation of convenient interior ring, and can prevent that vibration processes Intermediate gasket and upper magnetic conduction sheet from misplacing and getting loose.
As improvement, outside described magnetic circuit system, be arranged with the annular packing ring in the described basin frame, described packing ring is fixed on the basin frame.Packing ring is both dustproof, and playing again prevents from going between bumps the effect of playing the basin frame.
As improvement, described magnetic circuit system comprises magnetic conductor bowl, and described magnetic conductor bowl and described basin frame are formed in one.For making the reduced thickness of loud speaker, the basin frame is designed to the mode with the magnetic conductor bowl one, like this can be on the basis of attenuate, and loud speaker can be accomplished antimagnetic effect; And the centering of magnetic circuit mainly relies on the boss of basin frame bottom to carry out the centering location.
The utility model compared with prior art with beneficial effect be:
The utility model mainly is to realize large amplitude and ultra-thin characteristics by the thickness that reduces vibrational system; Cancelled centring disk in the vibrational system, but the form that adopts double folding ring reaches the effect with the centering of sound basin, after double folding ring is felt relieved the sound basin, relatively stable, the tapering of sound basin can be reduced, make the sound basin become more flat, in the situation that does not change the loud speaker whole height, help to enlarge the oscillation space of sound basin, thereby accomplished the slim design of loud speaker, guaranteed the requirement of Performance And Reliability again, and have the large characteristics of amplitude.
