The vibrating diaphragm of correlation technique comprise be positioned at middle part ball top, to stretch out from ball top and towards the ring portion of projection and the fixed part that is connected with ring portion.Wherein, described ring portion is provided with from ball top to some folds that fixed part extends.The structure of this vibrating diaphragm, often causes vibration of membrane disequilibrium of shaking, and the low-frequency distortion of vibrating diaphragm is very high.But in process of production, people are typically employed in the method for vibrating diaphragm being mended glue and balance vibration of membrane of shaking, but, mend glue and vibrating diaphragm can be made again to thicken, cause reducing of its oscillation space, and then its acoustic characteristic can be reduced.
Therefore, be necessary to provide a kind of new technical scheme to overcome above-mentioned technical problem.
[utility model content]
The purpose of this utility model is to provide a kind of vibrating diaphragm, and it is for solving existing vibration of membrane disequilibrium and the high technical problem of low-frequency distortion of shaking.
In order to solve the problems of the technologies described above, the utility model provides a kind of vibrating diaphragm, comprise the ring portion that the ball top that is positioned at centre position is connected with around ball top and with ball top, described ring portion is provided with fold, described fold comprises and protrudes from the first fold line of described folding collar surface and multiple the second fold line formed by described ring portion surface indentation around the multiple of ball top, and described first fold line and the second fold line interval that interlocks is arranged.
Above-mentioned vibrating diaphragm, described ring portion comprises and protrudes from the protuberance on described ball top and the edge part around described protuberance, and described fold is arranged on described protuberance.
Above-mentioned vibrating diaphragm, described protuberance is rectangular, and described fold is located at the corner of described protuberance.
Above-mentioned vibrating diaphragm, described first fold line is arranged along the outer surface protruding from described protuberance, and described second fold line is formed by the outer surface depressions of described protuberance.
Above-mentioned vibrating diaphragm, described first fold line and described second fold line all radially distribute towards the center of described vibrating diaphragm.
A kind of acoustical generator, comprise magnetic circuit system, vibrational system and accommodate the frame of magnetic circuit system and vibrational system, described vibrational system comprises vibrating diaphragm described above.
Above-mentioned acoustical generator, the protuberance of described vibrating diaphragm protrudes to the direction away from described magnetic circuit system.
Above-mentioned acoustical generator, the protrusion direction of described first fold line is identical with the protrusion direction of described protuberance.
The vibrating diaphragm that the utility model provides, can increase balance during diaphragm oscillations, reduces the non-linear of vibration, also can reduce low-frequency distortion simultaneously.
[accompanying drawing explanation]
Fig. 1 is the exploded view of the utility model acoustical generator;
Fig. 2 is the stereogram of vibrating diaphragm in Fig. 1;
Fig. 3 is the enlarged drawing of the a-quadrant of Fig. 2.
[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, for acoustical generator of the present utility model, its involving vibrations system, magnetic circuit system 40 and accommodate the frame 50 of described vibrational system and magnetic circuit system 40, the voice coil loudspeaker voice coil 30 that described vibrational system comprises vibrating diaphragm 100 and the driving vibrating diaphragm 100 that is connected with described vibrating diaphragm 100 vibrates.
As shown in Figures 2 and 3, described vibrating diaphragm 100 comprises the ball top 10 that is positioned at middle position and the ring portion 20 around ball top 10.The edge part 23 that described ring portion 20 comprises the connecting portion 21 be connected with described ball top 10, the rectangular projections 22 extended from described connecting portion 21 and extends outward from described protuberance 22.Described protuberance 22 protrudes to the direction away from described magnetic circuit system 40.Described vibrating diaphragm 100 is rectangle, and described protuberance 22 is annular, and ball top 10 is tabular, protuberance 22 is around described ball top 10, in addition, protuberance 22 is protruding arcuate structure and protrudes the surface at described ball top 10, can ensure that vibrating diaphragm 100 can freely up-down vibration.Protuberance 22 comprises four turnings 220, and each turning comprises the inner ring angle 2201 at close described ball top 10 and the outer shroud angle 2202 relative with described inner ring angle 2201.
Protuberance 22 is provided with fold and is used for suppressing polarization, improves the acoustical behavior of vibrating diaphragm 100.Fold can regulate the distribution in ring portion 20 as required.Generally for the vibration area of balance vibrating diaphragm, avoid vibrating diaphragm polarization, fold is at least provided with two groups, and two groups of folds are oppositely arranged, symmetrical, be evenly distributed on protuberance.In the present embodiment, fold is arranged on four corners of protuberance 22, and each fold comprises and multiplely protrudes from the first fold line 221 of the outer surface of protuberance 22 and multiple the second fold line 222 formed by the outer surface depressions of protuberance 22.First fold line 221 and the second fold line 222 interlock and are spaced.In the present embodiment, the second fold line 222 is arranged on outer shroud angle 2202, and the first fold line 221 is extended on inner ring angle 2201 by outer shroud angle 2202.In the present embodiment, the protrusion direction of the first fold line 221 is identical with the protrusion direction of protuberance 22.Fold effectively can reduce low-frequency distortion; In addition, the first fold line 221 and the second fold line 222 all radially distribute towards the center of vibrating diaphragm 100.Effectively solve the problem easily producing fold when vibrating diaphragm 100 vibrates thus, effectively suppress polarization, making vibrating diaphragm more steady when vibrating, increasing the compliance of vibrating diaphragm, obtaining more excellent low frequency performance.
Above-described is only better embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite not departing from the utility model creation design; improvement can also be made, but these all belong to protection range of the present utility model.
