A kind of stairstepping sound shake draining Loudspeaker diaphragmTechnical field
The utility model relates to a kind of stairstepping sound shake draining Loudspeaker diaphragm, and it belongs to the loudspeaker assembly class.
Background technology
Loudspeaker are a kind of application sounding equipment very widely, are commonly called as loud speaker.In application process, loudspeaker need to be tackled various complex environments, comprise the rainy day.Vibrating diaphragm is of paramount importance parts in loudspeaker, very big to the performance impact of loudspeaker, if loudspeaker are drenched by water, the tonequality of loudspeaker will be subject to important damage, for this reason very important of the water resistance of loudspeaker.In order to solve the water resistance of loudspeaker, there are many inventors to propose various solutions, comprise and adopt waterproof material to make vibrating diaphragm, be also included within on the Loudspeaker diaphragm made from non-watertight material and apply the coating that blocks water, particularity due to loudspeaker, adopt waterproof material and apply the coating that blocks water on Loudspeaker diaphragm all huge on the tonequality impact of loudspeaker, in this case, tonequality for not sacrificial property loudspeaker, also someone has proposed to apply the scheme of hydrophobic coating on the vibrating diaphragm of loudspeaker and the waterproof material of making vibrating diaphragm has been carried out to modification to promote tonequality, although the tonequality of the loudspeaker that aforesaid solution is improved to a certain extent, but the water resistance index descends to some extent, particularly Loudspeaker diaphragm is subject in the situation of water erosion for a long time, the performance of loudspeaker can be subject to larger impact, in addition that to make be the loudspeaker that adopt the particularly preferred diaphragm materials of water resistance to make, when on vibrating diaphragm, collection has water, its tonequality also can be subject to larger impact, obviously prior art has further improved necessity.
Summary of the invention
The purpose of this utility model is to provide a kind of stairstepping sound shake draining Loudspeaker diaphragm, is subject to the possibility of water logging erosion to reduce Loudspeaker diaphragm, thereby solves the problem that prior art exists.
A kind of stairstepping sound shake draining Loudspeaker diaphragm of the present utility model, comprise the vibrating diaphragm body, it is characterized in that described vibrating diaphragm body comprises Huan Zhong district and some circles of the convex arc around Huan Zhongqu, described some convex arc circles link in turn, and the height and position of described convex arc circle descends in turn from the inside to surface, form stepped.
As further improvement, the convex arc of described convex arc circle is shaped as circular arc, and preferably arc length is whole circumference 1/4th.
This stairstepping sound shake draining Loudspeaker diaphragm of the present utility model, the position of each convex arc circle progressively reduces from inside to outside, and one-tenth convex arc shaped, if there is water droplet to drop on Loudspeaker diaphragm for this reason, under the effect of gravity, it can flow to low position on the one hand, while working on the other hand, the vibration of Loudspeaker diaphragm will make this water droplet be subject to outside kinetic energy, thereby be shaken from the Loudspeaker diaphragm surface.This stairstepping sound shake draining Loudspeaker diaphragm of the present utility model, owing to thering is sound shake drain function, no matter be to be used on the Loudspeaker diaphragm that has applied the coating that blocks water for this reason, still be used on the Loudspeaker diaphragm that has applied hydrophobic coating, or even be used in and adopt on the Loudspeaker diaphragm that complete waterproof material makes, to maintaining and keeping the tonequality of loudspeaker that good effect is all arranged, obviously the purpose of this utility model is achieved.

Embodiment
The utility model is described in further detail for a kind of stairstepping sound shake draining Loudspeaker diaphragm provided below with reference to the utility model preferred embodiment and accompanying drawing thereof.
A kind of stairstepping sound shake draining Loudspeaker diaphragm that the utility model preferred embodiment provides, as described in Figure 1, comprise the vibrating diaphragm body, in this preferred embodiment, described vibrating diaphragm body comprises Huan Zhong district 1 and five circles of the convex arc around Huan Zhongqu 2, described five convex arc circles 2 link in turn, and the height and position of described convex arc circle 2 descends in turn from the inside to surface, forms stepped.
In this preferred embodiment, the convex arc of described convex arc circle 2 is shaped as circular arc, and arc length is whole circumference 1/4th.
In sum, a kind of stairstepping sound shake draining Loudspeaker diaphragm of the present utility model, comprise the vibrating diaphragm body, it is characterized in that described vibrating diaphragm body comprises Huan Zhong district and some circles of the convex arc around Huan Zhongqu, described some convex arc circles link in turn, and the height and position of described convex arc circle descends in turn from the inside to surface, forms stepped, the utility model can shake draining by sound when work, to improving and keeping tone quality of horn that positive effect is arranged.
The above is only embodiment of the present utility model.But the utility model protection range is not limited to this.Anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement; within all should being encompassed in protection range of the present utility model, therefore, protection range of the present utility model should be as the criterion with the protection range of claim.
