Abstract
The utility model provides a centring support sheet in a loudspeaker. The centring support sheet in a loudspeaker comprises a centring support sheet body and a round via hole arranged in the middle of the centring support sheet body, and the cross-sectional area of the centring support sheet is shaped as a polygon. The centring support sheet in a loudspeaker is characterized by reasonable design, simple structure, ease of manufacture, operability, convenience of use, reliability, long service life, and good work effects.
Description
Technical field
The utility model has related to loudspeaker techniques field, has been specifically related to the centring disk in loud speaker.
Background technology
Centring disk is one of critical piece of speaker vibration system.In prior art, the general centring disk adopting is all circular, the centring disk of this structure requires high to process technology, manufacturing procedure is many, makes trouble, and in the process of processing, be easy to, because technological deficiency causes the polishing of centring disk circular arc level and smooth not, affect its working effect.Because the defect of above-mentioned general centring disk, it does not reach perfection inventor's thoughts, then exhausting the concentrated research of its intelligence overcomes, be engaged in this industry accumulating experience for many years with it, and then develop a kind of centring disk, utilize simple design, can make the utility model reach effect of easy to manufacture and good working effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide the centring disk in loud speaker, reasonable in design, simple in structure, easy to manufacture, has operability, easy to use, reliable, long service life, good working effect.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the centring disk in loud speaker, comprise centring disk body and be arranged on the middle manhole of centring disk body, the cross-sectional area of described centring disk body is set to polygon, on the corresponding centring disk body of described centring disk body adjacent edge, be respectively equipped with locating convex block, the opposite side length of side of described centring disk body equates.
Beneficial effect:
The utility model adopts technique scheme that the centring disk in loud speaker is provided, and has made up the deficiencies in the prior art, has improved structural stability, reasonable in design, simple in structure, easy to manufacture, there is operability, easy to use, reliable, long service life, good working effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cutaway view of the present utility model.
Embodiment
As shown in Fig. 1-2, centring disk in loud speaker, comprise centring disk body 1 and be arranged on the middle manhole 2 of centring disk body 1, the cross-sectional area of described centring disk body 1 is set to polygon, on the corresponding centring disk body 1 of described centring disk body 1 adjacent edge, be respectively equipped with locating convex block 3, the opposite side length of side of described centring disk body 1 equates.
When real work, centring disk body 1 is arranged in the framework of loud speaker, centring disk body 1 is provided with locating convex block 3, can make working effect better, the cross-sectional area of centring disk body 1 is set to shape changeable, convenient manufacture, easily processing, avoid the circular setting of available technology adopting, because the defect of technical matters makes to exist on centring disk body a lot of hangnails, affect working effect, after technological improvement, can better remain on the tram of voice coil loudspeaker voice coil in magnetic seam, keep voice coil loudspeaker voice coil when stressed, vibrational system is only along axially reciprocating, can also prevent that dust from entering magnetic gap, can be better and the vibrating diaphragm voice coil loudspeaker voice coil of vibrational system jointly determine the resonance frequency of loud speaker.Make up the deficiencies in the prior art, improved structural stability, reasonable in design, simple in structure, easy to manufacture, there is operability, easy to use, reliable, long service life, good working effect.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
