Abstract
The utility model discloses a miniature moving-coil sounder diaphragm, which comprises a dome part, an annular folding ring part and a fixing part. The annular folding ring part surrounds the dome part and is combined with the dome part in a sealing way. Folding rings are arranged on the folding ring part. The internal edge and the external edge of the folding ring part are respectively in arc transition at the corners of the folding ring part. An annular connecting part which is arranged along the folding ring part is arranged at the top of the folding ring part. The external edge of the connecting part is equidistant to the external edge of the folding ring part. The internal edge of the connecting part is equidistant to the internal edge of the folding ring part. Since the connecting part is arranged in the area of the corners of the diaphragm, the internal edge of the folding ring part and the external edge of the folding ring part are respectively equidistant to the connecting part and the corners of the diaphragm are symmetrical, polarization is not caused, the vibration of the diaphragm is more balanced, the collision and the noise caused by unbalanced vibration can be reduced and the diaphragm which has better tone quality and better acoustic performance can be obtained.

Background technology
Along with the development in portable consumer electronic product market, a large amount of microphone device particularly moving-coil type acoustical generator has obtained using widely.As everyone knows, the moving-coil type acoustical generator is by voice coil loudspeaker voice coil stressed in the magnetic gap that is produced by magnet, drives vibrating diaphragm and sounds along the vertical direction vibration.
In the traditional structure, the vibrating diaphragm of square structure is a kind of structure commonly used, as shown in Figure 5, vibrating diaphragm is a rectangle structure, comprise central part 2 that is positioned at the vibrating diaphragm central area and the ring portion 1 that is provided with around central part 2, the edge of ring portion 1 also is combined with the fixed part 3 of integrative-structure, wherein ring portion 1 adjacent inward flange and outward flange passes through arc transition respectively, and inner corner region and four outer corner regions that radius is r that to form four radiuses respectively on vibrating diaphragm be R, and radius R is greater than radius r, to guarantee the size and the swept area of vibrating diaphragm, to obtain good vibration and acoustical behavior (also the structural behaviour that decorative pattern strengthens the vibrating diaphragm bight can be set simultaneously); Ring portion 1 is s ' in the distance of its outer edge of position, axle limit, is s in the distance of its outer edge of corner positions, can draw s greater than s '.
The vibrating diaphragm of this structure, because the distance between the outer edge of ring portion 1 is unequal, four jiaos of places are inequality with the Oscillation Amplitude of position, vibrating diaphragm axle limit, cause the unbalanced deformation of vibrating diaphragm itself, cause the vibration of vibrating diaphragm unbalanced easily, cause producing collision and noise, and this design vibrating diaphragm stress is concentrated, make the vibrating diaphragm fracture by fatigue easily, cause the bad of acoustical behavior.So be necessary the vibrating diaphragm of above-mentioned traditional structure is further improved, to avoid above-mentioned defective.
The utility model content
Technical problem to be solved in the utility model provides a kind of miniature moving-coil type acoustical generator vibrating diaphragm, the bight symmetry of vibrating diaphragm, thus can not produce polarization, make described vibrating diaphragm vibration balanced more, reduce collision and noise that unbalanced vibration brings, to obtain the vibrating diaphragm of better tonequality and acoustical behavior.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of miniature moving-coil type acoustical generator vibrating diaphragm, be rectangle structure, and comprise the ball top, described ball top is positioned at the center of described vibrating diaphragm; The ring portion of annular, around described ball top be provided with and with airtight combination the in described ball top, described ring portion is provided with the ring perpendicular to the globoidal structure of described vibrating diaphragm, and ring portion inward flange and ring portion outward flange are respectively in the curved transition in bight of described ring portion; Fixed part around setting, is fixed on the described miniature moving-coil type acoustical generator described vibrating diaphragm along described ring portion outward flange; And: the top of described ring portion is provided with the connecting portion of the annular that is provided with along described ring portion, and described connecting portion outward flange and described ring portion outward flange are equidistant, and described connecting portion inward flange and described ring portion inward flange are equidistant.
As a kind of optimized technical scheme, described connecting portion is a planar structure.
As a kind of optimized technical scheme, described connecting portion is a crescent; The connecting portion inward flange and the connecting portion outward flange that are positioned at the connecting portion on the straight flange of described ring portion overlap.
As a kind of optimized technical scheme, the bight of described ring portion is provided with gauffer.
As a kind of optimized technical scheme, described ball top and described ring portion are absolute construction.
As a kind of optimized technical scheme, described ball also is provided with location hole on the top.
Owing to adopted technique scheme, on the folding corner region of vibrating diaphragm, be provided with connecting portion, ring portion inward flange equates respectively with the ring portion outward flange distance to connecting portion, make the bight symmetry of described vibrating diaphragm, thereby can not produce polarization, make described vibrating diaphragm vibration balanced more, reduce collision and noise that unbalanced vibration brings, to obtain the vibrating diaphragm of better tonequality and acoustical behavior.

Embodiment
Below, describe each embodiment of the present utility model in conjunction with the accompanying drawings in detail.
In the following detailed description, only some one exemplary embodiment of the present utility model has been described by the mode of explanation.Undoubtedly, those of ordinary skill in the art can recognize, can revise described embodiment with various mode and do not depart from spirit and scope of the present utility model.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used to limit the protection range of claim.In addition, in this manual, identical Reference numeral is represented identical part.
Embodiment one:
Fig. 1 is the stereogram of the utility model embodiment one; Fig. 2 is the vertical view of the utility model embodiment one; Fig. 3 is the cutaway view of the utility model embodiment one.As Fig. 1, Fig. 2 and shown in Figure 3, described vibrating diaphragm is a rectangle, comprises the ball top 2 that is positioned at the vibrating diaphragm center and around the ring portion 1 that is arranged on 2 edges, ball top, ball top 2 and ring portion 1 are the absolute construction of split, and both airtight combining.
Also be provided with the fixed part 3 of one along ring portion outward flange, fixed part 3 can be installed in described vibrating diaphragm is fixed.
