Abstract
The utility model discloses a kind of earpiece dust guard, including steel wire supporting layer, dustproof sponge, attachment screw, steel wire supporting layer is divided into two layers up and down, and dustproof sponge is fixed among steel wire supporting layer.The utility model can effectively prevent the tiny particles contents such as dust from entering interior of mobile phone, and the transmission of sound is not interfered with using the structure of the good sponge of air permeable effect and steel wire supporting layer yet, ensure that the sound quality of receiver.
Description
Technical field
A kind of field of mobile phones is the utility model is related to, more particularly to a kind of earpiece dust guard.
Background technology
Mobile phone has turned into the essential instrument of people in modern day life, due to often using out of doors and
Close contact human body, upper many dirt bodies, dirt are inevitably infected with, once these dirt bodies, dirt invade interior of mobile phone,
The service behaviour of interior of mobile phone electronic component can be influenceed or even destroy electronic component, as the Open architecture on mobile phone surface, hand
Machine receiver is even more the main thoroughfare that various dusts enter interior of mobile phone.
Therefore those skilled in the art are directed to developing a kind of earpiece dust guard.
Utility model content
In view of the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of mobile phone and listened
Cylinder dust guard.
To achieve the above object, the utility model provides a kind of earpiece dust guard, including steel wire supporting layer,
Dustproof sponge, attachment screw, it is characterized in that：Steel wire supporting layer is divided into two layers up and down, and dustproof sponge is fixed on steel wire support
Among layer.
The steel wire supporting layer side structure is the structure of interlude bending, and centre bending segment length is equal to described dust-proof
The length of sponge.
Described four angles of steel wire supporting layer are provided with screw, and the attachment screw connects the steel wire through screw
Two layers up and down of supporting layer.
Described dustproof sponge selects Antistatic type special type sponge.
The beneficial effects of the utility model are：The utility model can effectively prevent the tiny particles contents such as dust from entering to start with
Inside machine, the transmission of sound is not interfered with using the structure of the good sponge of air permeable effect and steel wire supporting layer yet, is ensured
The sound quality of receiver.
Brief description of the drawings
Fig. 1 is overlooking the structure diagram of the present utility model.
Fig. 2 is side structure schematic view of the present utility model.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
As depicted in figs. 1 and 2, a kind of earpiece dust guard, including steel wire supporting layer 1, dustproof sponge 2, connection
Screw 3, steel wire supporting layer 1 divide for upper and lower two layers, and dustproof sponge 2 is fixed among steel wire supporting layer.Steel wire supporting layer 1
Side structure is the structure of interlude bending, and centre bending segment length is equal to the length of dustproof sponge 2.Steel wire supporting layer 1 four
Individual angle is provided with screw, and attachment screw 3 connects two layers up and down of steel wire supporting layer through screw.Dustproof sponge is from antistatic
Type special type sponge.
In use, the present apparatus is embedded in into clamping between mobile phone shell and earpiece, dustproof sponge is set to cover whole receiver area
Domain, can effectively prevent the tiny particles contents such as dust from entering interior of mobile phone, moreover it is possible to ensure the transmission effect of earpiece sound not by
Influence.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member makes many modifications and variations without creative work can according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
