Abstract
The invention 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 present invention 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
The present invention relates to a kind of field of mobile phones, 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.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of earpiece and prevented
Dirt device.
To achieve the above object, the invention provides a kind of earpiece dust guard, including it is steel wire supporting layer, dust-proof
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 in steel wire supporting layer
Between.
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 invention are as follows：The present invention can effectively prevent the tiny particles contents such as dust from entering interior of mobile phone, use
The structure of the good sponge of air permeable effect and steel wire supporting layer does not interfere with the transmission of sound yet, ensure that the sound of receiver
Quality.
Brief description of the drawings
Fig. 1 is the overlooking the structure diagram of the present invention.
Fig. 2 is the side structure schematic view of the present invention.
Embodiment
The invention will be further described 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, attachment screw
3, steel wire supporting layer 1 divides for upper and lower two layers, and dustproof sponge 2 is fixed among steel wire supporting layer.The side of steel wire supporting layer 1
Structure is the structure of interlude bending, and centre bending segment length is equal to the length of dustproof sponge 2.1 four angles of steel wire supporting layer
Screw is provided with, attachment screw 3 connects two layers up and down of steel wire supporting layer through screw.Dustproof sponge is special from Antistatic type
Kind 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 invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Creative work can is needed to make many modifications and variations according to the design of the present invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, all should be in the protection domain being defined in the patent claims.
