Abstract
The utility model discloses a vibrating diaphragm, which comprises a ball top, wherein at least two layers of drape parts are arranged from the center of the ball top to the outer edge, and any layer of the drape parts is provided with a plurality of discontinuous drapes, and the drapes of the adjacent layers are not continuous. The vibrating diaphragm has the following advantages: 1. the strength of the ball top is effectively improved; 2. the distortion of the high-frequency peak is reduced; 3. the sound quality of the high frequency is good.
Description
[technical field]
The utility model relates to a kind of microphone device, particularly the vibrating diaphragm of mini-sound device.
[background technology]
Along with improving constantly of the market demand, mobile phone develops to the slimming direction gradually, and requires its sound quality to become better and better, and this just requires the acoustical device in the mobile phone to develop towards small-sized, slim, high tone quality.Vibrating diaphragm is the core component of acoustical device such as loud speaker, and the requirement of its acoustical behavior is also just improved thereupon.
In order to address the above problem, active development vibrating diaphragm in the industry.
As shown in Figure 3, a kind of vibrating diaphragm 1 ' of correlation technique, its middle part is provided with ball top 11 ', and described ball top 11 ' is circular arc.
As shown in Figure 4, the vibrating diaphragm 2 ' of another kind of correlation technique, its middle part is provided with ball top 21 ', and described ball top 21 ' is provided with continuous fold 22 '.
Yet there is common shortcoming in the vibrating diaphragm of above correlation technique: intensity is not high, easily form the spike distortion at HFS, the high frequency acoustical quality is undesirable.
Therefore, be necessary to provide a kind of new vibrating diaphragm to overcome above-mentioned shortcoming.
[utility model content]
The purpose of this utility model is to provide a kind of intensity height, distortion is little, high frequency tonequality is satisfactory for result vibrating diaphragm.
The purpose of this utility model is achieved in that
A kind of vibrating diaphragm, it comprises the ball top, and wherein, its outer rim of mind-set is laid with two-layer at least pleated portions in described ball top, and the random layer pleated portions is provided with some discontinuous folds, and the fold of adjacent layer is also discontinuous.
Compare with the vibrating diaphragm of correlation technique, the utlity model has following advantage: one, effectively strengthened ball top intensity; Two, reduced the distortion of high frequency spike; Three, high frequency tonequality is satisfactory for result.

Fig. 2 is the schematic diagram of second kind of execution mode of the utility model vibrating diaphragm.
Fig. 3 is the schematic diagram of the vibrating diaphragm of correlation technique.
Fig. 4 is the schematic diagram of the vibrating diaphragm of another kind of correlation technique.
[embodiment]
Below in conjunction with accompanying drawing, the utility model vibrating diaphragm is elaborated.
As shown in Figure 1, first kind of execution mode of the present utility model.
The vibrating diaphragm 1 of present embodiment is applied on the mini-sound device (not shown), and it comprises that the ball in the middle of being positioned at pushes up 11, pushes up 11 outward extending extensions 12 and the holding parts 13 that is connected extension 12 from ball.Wherein, its outer rim of middle mind-set from ball top 11 is laid with ground floor pleated portions (not label) and second layer pleated portions (not label) successively, and this ground floor pleated portions is provided with some first folds 14; Second layer pleated portions is provided with some second folds 15, and described any two first folds 14 are discontinuous; Any two second folds 15 are discontinuous; Any first fold 14 and second fold 15 are also discontinuous.
As selection, vibrating diaphragm 1 can be rectangle, circle, runway shape or other shapes, and is same, and ball top 11 can also be rectangular, circular, runway shape or other shapes.
As shown in Figure 2, second kind of execution mode of the present utility model.
Second kind of execution mode of the present utility model and first kind of execution mode are roughly the same, and different is first fold 14 ' of its ground floor pleated portions and second fold, the 15 ' interlaced arrangement of second layer pleated portions.
Vibrating diaphragm 1 of the present utility model has the following advantages: one, effectively strengthened ball top intensity; Two, reduced the distortion of high frequency spike; Three, the high frequency acoustical quality is more satisfactory.
The ball top only is shown in the above execution mode is provided with two-layer pleated portions, the ball top can be provided with three layers or multilayered fold portion as required in fact, as long as pleated portions is provided with some folds arbitrarily, the fold of random layer is discontinuous, and the fold of adjacent layer is also discontinuous.
The above only is a better embodiment of the present utility model; protection range of the present utility model does not exceed with above-mentioned execution mode; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of putting down in writing in claims.
Claims (2)
1. vibrating diaphragm, it comprises the ball top, it is characterized in that: its outer rim of mind-set is laid with two-layer at least pleated portions in described ball top, and the random layer pleated portions is provided with some discontinuous folds, and the fold of adjacent layer is also discontinuous.
2. vibrating diaphragm according to claim 1 is characterized in that: the fold interlaced arrangement of described adjacent layer.
