Embodiment:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
Shown in Figure 1, the coil-moving speaker of the outstanding limit of a kind of plural number structure, it comprises: support 1, the magnetic of Matching installation return assembly 2, voice coil loudspeaker voice coil 3, centring disk 4, oscillating plate 5, outstanding limit 6 and dust cap 7 mutually.
In described support 1, there is a tank 11, in this tank 11, be formed with the first circular step 12 and the second circular step 13, the second circular steps 13 are positioned at tank 11 upper ends.
Described magnetic returns assembly 2 and is fixed on the bottom of support 1, and its upper end core is corresponding with support 1 bottom centre.Described magnetic returns assembly 2 and comprises: a lower plate 21 and be installed on successively magnet 22 and the train wheel bridge 23 on lower plate 21, conflicts in the bottom of train wheel bridge 23 upper surfaces and support 1.Wherein, the cross section of described lower plate 21 is inverted T-shape, and all in the form of a ring, this magnet 22 and train wheel bridge 23 are fixedly sleeved on lower plate 21 for magnet 22 and train wheel bridge 23.
Described voice coil loudspeaker voice coil 3, this voice coil loudspeaker voice coil 3 is installed magnetic and is returned on assembly 2, and stretches in the tank 11 of support 1.
Described centring disk 4 one end are installed in support 1 on the first circular step 12, and the other end and voice coil loudspeaker voice coil 3 are peripheral fixing.
The cross section undulate of described centring disk 4, can strengthen the intensity of centring disk 4.
Described oscillating plate 5 is funnel-form, and its lower end is fixed by socket in voice coil loudspeaker voice coil 3 peripheries, and is positioned at centring disk 4 tops; Wherein, this oscillating plate 5 can be lower mobile in a longitudinal direction, and particularly, oscillating plate 5 can carry out the reciprocating motion of above-below direction by described outstanding limit 6.
The second circular step 13 laminatings in the outward flange on described outstanding limit 6 and support 1 are fixing, the inward flange on this outstanding limit 6 is connected with oscillating plate 5 upper ends, wherein, in outstanding limit 6, be formed with a plurality of continuous annular protrusions 61, the cross section semicircular in shape of this annular protrusion 61 or arc or other geometry.Such structure can be strengthened the intensity on outstanding limit greatly, so that the deflection that outstanding limit produces is stable, thereby the reciprocating linear relationship that ensures oscillating plate is first to stable, can avoid like this distortion, ensures psycho-acoustical quality.
The inward flange on described outstanding limit 6 is downward-sloping, and fixing with oscillating plate 5 upper end madial wall laminatings.
6 upper surfaces, described outstanding limit flush with support 1 upper surface, reduce like this thickness of the utility model agent structure, are conducive to the utility model towards lightening development, to meet the demand of different manufacturers.
In the present embodiment, in outstanding limit 6, be formed with three continuous annular protrusions 61, it cooperatively interacts can, in the situation that not amplifying, just can provide enough resilience forces, makes oscillating plate 5 Quick-returns to initial position.Therefore, when the utility model uses as long stroke loud speaker, when needing performance greatly dynamically or producing ultralow frequency sound, even if oscillating plate 5 produces high vibration or larger stroke, outstanding limit 6 still can guarantee that the reciprocating motion of oscillating plate 5 is smooth, reduces distortion, ensures psycho-acoustical quality.Outstanding limit 6 also can remain on relatively thin size simultaneously, so that the utility model can further be applied in the acoustics of light and thin type.
