A kind of loud speaker, it comprises the basin frame, is contained in magnetic circuit system and vibrational system in the described basin frame.Described vibrational system comprises the vibrating diaphragm that is provided with ball top and ring section, be sticked at the voice coil loudspeaker voice coil at described ball top and be fixed on centring disk on the described vibrating diaphragm.Wherein, described centring disk comprises the inner arm of annular, the outer arm and the elasticity arm that is connected described inner arm and described outer arm of annular, and described elasticity arm and described inner arm are not at grade.Described inner arm is fixed on the described ball top, and described outer arm is fixed on the described basin frame, and described elasticity arm is fixed in the described ring section.
Preferably, the inner arm of described centring disk and outer arm are positioned on the same level.
Preferably, the ball top of described vibrating diaphragm and ring section are Split type structure, and described centring disk is fixed between described ball top and the described ring section.
Preferably, described centring disk is made by electric conducting material, and described voice coil loudspeaker voice coil is electrically connected with external circuit by described centring disk.
Preferably, described centring disk also comprises by described inner arm and extends the first junction separated by a distance and by extended the second junction separated by a distance of described outer arm, described the first junction is electrically connected with voice coil loudspeaker voice coil, and described the second junction is electrically connected to external circuit.
Preferably, described elasticity arm is provided with two and separated by a distance.
Compare with correlation technique, its acoustical behavior of the utility model loud speaker is more stable more excellent.

[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
Shown in Fig. 1-2, a kind of loud speaker 10, it comprises basin frame 1, is contained in magnetic circuit system 2 and vibrational system 3 in the basin frame 1.In conjunction with shown in Figure 3, vibrational system 3 comprises the vibrating diaphragm 31 that is provided with ball top 311 and ring section 312, be sticked at the voice coil loudspeaker voice coil 32 at ball top 311 and be fixed on centring disk 33 on the vibrating diaphragm 31.
In the lump with reference to Fig. 4, centring disk 33 comprise annular inner arm 331, annular outer arm 332 and is connected the elasticity arm 333 of inner arm 331 and outer arm 332, elasticity arm 333 and inner arm 331 are not at grade.Inner arm 331 is fixed on the ball top 311, and outer arm is fixed on the basin frame 1, and elasticity arm 333 is fixed in the ring section 312.In the present embodiment, elasticity arm 333 and inner arm 331 not at grade, namely elasticity arm 333 was higher than the plane that is lower than inner arm 331 places.Because elasticity arm 333 is fixed in the ring section 312, and ring section 312 is sunk structure.If ring section 312 is that then elasticity arm 333 is higher than the plane at inner arm 331 places to the direction depression away from voice coil loudspeaker voice coil 32; If ring section 312 is that then elasticity arm 333 is on the plane that is lower than inner arm 331 places to the direction depression near voice coil loudspeaker voice coil 32.More excellent, in the present embodiment, inner arm 331 and outer arm 332 are positioned on the same level, have better guaranteed the balance when centring disk 33 vibrates, and have improved the stability of loud speaker 10.
In the present embodiment, the ball top 311 of vibrating diaphragm 31 and ring section 312 are Split type structure, and centring disk 33 is fixed between ball top 311 and the ring section 312.
When vibrating diaphragm 31 vibration, the elasticity arm 333 of centring disk 33 is because being fixed in the ring section 312 and thereupon together vibration, therefore elasticity arm 333 can not occur because producing the phenomenon that resonates with 312 collisions of ring section, avoid the generation of collision noise and beat, optimized the acoustical behavior of loud speaker 10; Elasticity arm 333 also is not easy fracture, thereby has improved the stability of the utility model loud speaker 10.
In the present embodiment, centring disk 33 is made by electric conducting material, and voice coil loudspeaker voice coil 32 is electrically connected with external circuit by centring disk 33, thereby provides the signal of telecommunication for voice coil loudspeaker voice coil 32.More excellent, centring disk 33 also comprises by inner arm 331 and extends the first junction 3311 separated by a distance and by outer arm 332 extended the second junctions 3321 separated by a distance, the first junction 3311 is electrically connected with voice coil loudspeaker voice coil 32, the second junction 3321 is electrically connected to external circuit, thereby provides the signal of telecommunication for voice coil loudspeaker voice coil 32.Certainly, also can be at centring disk 33 conductive layer to be set, again voice coil loudspeaker voice coil 32 is electrically connected with conductive layer, equally also realized as voice coil loudspeaker voice coil 32 provides the signal of telecommunication, its principle is all the same.
Compare with correlation technique, the no longer unsettled setting of the elasticity arm of its centring disk of the utility model loud speaker, but elasticity arm is fixed in the ring section of vibrating diaphragm, thereby avoided elasticity arm to bump with ring section because producing resonance, and then avoided the generation of noise and beat, improved the acoustical behavior of loud speaker, and elasticity arm is because vibrating after fixing and with ring section, be difficult for fracture, further improved the stability of the utility model loud speaker.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
