annular edge, it is the annular matching with the first end of described film body and is connected on the first end of described film body, and described annular edge has elasticity;
balanced sheet, it is for sheet and be at least three, and described balanced sheet is all fixedly installed on the front and/or the back side of described film body.
preferably, described balanced sheet pastes on the front that is arranged at described film body.
preferably, described balanced sheet is uniformly-spaced arranged along the circumferencial direction of described film body.
more preferably, each balanced sheet is along the extension of the direction to the second end from described film body first end.
preferably, described balanced sheet and described annular edge are integrated setting.
preferably, between each balanced sheet and described annular edge, all there is a spacing.Be not non-being wholely set of balanced sheet and annular edge, be not connected between mutually.
preferably, described balanced sheet is made by having internally-damped material.
preferably, described balanced sheet is made up of rubber, silica gel or expanded material.
the utility model adopts above structure, tool has the following advantages compared to existing technology: disperse diaphagras by the multiple balanced sheet that is arranged on the high frequency region in film body front and/or intermediate frequency zone, the spike that reduction is even eliminated diaphagras in high frequency region and/or intermediate frequency zone causes, reduces distortion; Because balanced sheet has wider distribution and larger area, its overlayable frequency range is wider, can reduce the distortion in a wider frequency range in addition.

Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be those skilled in the art will recognize that, protection range of the present utility model is made to more explicit defining.The first end of the film body of addressing in the utility model and the second end correspond respectively to the top and bottom of its paper in Fig. 2, front and back is arranged on loud speaker and defines according to vibrating diaphragm, the surface that front still can be seen after referring to and being installed on loud speaker.
embodiment mono-
shown in Fig. 1 and Fig. 2, a kind of vibrating diaphragm, it comprises: film body 1, it is the frustroconical of hollow or horn-like substantially, described film body 1 has first end and the second end, is formed at the front and back between described first end and the second end, and the internal diameter of described first end is greater than the internal diameter of the second end; Annular edge 3, it is the annular matching with the first end of described film body 1 and is connected on the first end of described film body 1, and described annular edge 3 has elasticity; Balanced sheet 2, it is for sheet and be three, and described balanced sheet 2 is all fixedly installed on the front of described film body 1.Flexible annular edge 3 has two effects: be in the time that vibrating diaphragm is installed on loud speaker on the one hand, the first end of vibrating diaphragm (being neighboring) is bonded on loud speaker by annular edge 3; Annular edge 3 is equivalent to the quality load of a ring shape on the other hand, for reducing the diaphagras of edge.
described balanced sheet 2 pastes on the front that is arranged at described film body 1, is to be generally adhered on film body 1.Three described balanced sheets 2 are uniformly-spaced arranged along the circumferencial direction of described film body 1.Each balanced sheet 2, along from described film body 1 first end, the extension of the direction to the second end also narrows gradually, is a part for an annulus substantially.Described balanced sheet 2 is integrated and arranges and extend to the second end of film body 1 with described annular edge 3.Laminar balanced sheet 2 pastes the medium-high frequency district that is arranged at film body 1, and is uniformly-spaced and arranges, and can reduce and even eliminate diaphagras in high frequency region and/or spike that intermediate frequency zone causes, reduces distortion.Because balanced sheet 2 is laminar, its quality is very light in addition, therefore has higher sensitivity and can balanced wider frequency range; Balanced sheet 2 is distributed with more than three, has better stability, and inhibition degree is better, even if each balanced sheet 2 exists small error, still has good stability; Because balanced sheet 2 has wider distribution and larger area, its overlayable frequency range is wider, can reduce the distortion in a wider frequency range in addition
described balanced sheet 2 has elasticity and makes by having internally-damped material, the distortion being brought by balanced sheet 2 quality own while avoiding vibrating.Particularly, described balanced sheet is made up of rubber, silica gel or expanded material.
embodiment bis-
shown in Fig. 3 and Fig. 4, embodiment bis-is that with the difference of embodiment mono-balanced sheet 2 is five.Five balanced sheets 2 uniformly-spaced arrange along the circumferencial direction of film body 1, a part that is shaped as an annulus for balanced sheet 2.The even annular edge 3 of balanced sheet 2 is connected and is integrated setting.
embodiment tri-
shown in Fig. 5 and Fig. 6, embodiment tri-is that with the difference of embodiment mono-balanced sheet 2 is five and is not connected with annular edge 3.Five balanced sheets 2 uniformly-spaced arrange along the circumferencial direction of film body 1, a part that is shaped as an annulus for balanced sheet 2, balanced sheet 2 and annular edge 3 mutually near but do not join.In addition, according to the bore of concrete vibrating diaphragm and Frequency point distribution situation, balanced sheet 2 also can make to have a spacing between the two away from annular edge 3 setting, and annulus and annular edge 3 that five balanced sheets 2 form are not joined.
embodiment tetra-
shown in Fig. 7, embodiment tetra-is that from the difference of embodiment mono-shape of balanced sheet 2 is different, and the part edge of balanced sheet 2 is roughly arcuation.
to sum up, distribute according to the bore of each vibrating diaphragm and Frequency point, different numbers, shape can be set, radially extend the balanced sheet 2 of the degree of depth, width, thickness and material, to obtain optimum portfolio effect, farthest reduce even to eliminate the distortion causing from the diaphagras in diaphragm medium-high frequency district by producing.
by the vibrating diaphragm of embodiment mono-and the vibrating diaphragm comparing result that balanced sheet 2 is not set traditional in prior art as shown in Figure 8 and Figure 9.In Fig. 7, the more shallow curve of color is the frequency response curve that adopts the loud speaker of the vibrating diaphragm assembling of embodiment mono-, the darker curve of color is the frequency response curve that adopts the loud speaker of the vibrating diaphragm assembling that balanced sheet 2 is not set in prior art, can find out, all there is the loud speaker of the vibrating diaphragm of balanced sheet 2 can reduce respectively and draw high spike and the low ebb of 2KHz with super band, the more shallow frequency response curve of color is obviously more level and smooth, sound is more melodized, seldom produces harsh noise.In Fig. 8, the more shallow curve of color is to adopt the loud speaker of vibrating diaphragm assembling of embodiment mono-at the total harmonic distortion degree of each frequency band, the darker curve of color is the loud speaker of vibrating diaphragm assembling of balanced sheet 2 not to be set at the total harmonic distortion degree of each frequency band in adopting in prior art, can find out, the loud speaker of the vibrating diaphragm assembling of embodiment mono-almost the total harmonic distortion degree of each frequency band all lower than prior art in the loud speaker of vibrating diaphragm assembling, the more close primary sound of its sound effect, the distortion factor is less.
above-described embodiment is only explanation technical conceive of the present utility model and feature; it is a kind of preferred embodiment; its object is that person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations of doing according to Spirit Essence of the present utility model or modification, within all should being encompassed in protection range of the present utility model.
