Background technology
Press, have the microphone that can transmit sound effect and be widely used, its major function is to provide the voice signal transmission.In recent years, along with various light and handy shape consumption electronic products, as the development of mobile phone, PDA, MP3 and mobile computer etc., the application of microphone connector on these products seems more important.
See also Fig. 5, the microphone connector 30a that tradition is applied on the consumption electronic product roughly includes a plastic casing 301a, has a room 302a in the plastic casing 301a, in room 302a, be embedded with plural contact terminal 303a, these contact terminals 303a one 3031a of end in contact portion inclination perk is in room 302a, in order to do the conducting that contacts with microphone assembly 20a contact upward, other end weld part 3032a then is convexly equipped with for outside the plastic casing 301a.This microphone connector 30a is welded on the interior printed circuit board (PCB) tops of consumption electronic product such as mobile phone, make the circuit junction on the weld part 3032a territory printed circuit board (PCB) of the last contact terminal 303a of microphone connector 30a be welded on mutually together, succeed in the room 302a that again a microphone assembly 20a is placed on microphone connector 30a and get final product.
And general consumption electronic product such as mobile phone are in use, source of sound sees through the hole at mobile phone front panel place earlier, be passed to again on the microphone assembly 20a of mobile phone inside, only, source of sound there is no any isolation in the process that is passed to microphone assembly 20a, make source of sound can't gather sound, and to outdiffusion, and can be subjected to unnecessary noise interference.
The utility model content
For the source of sound that solves microphone assembly in the above-mentioned prior art can't gather sound, and can be to outdiffusion, and can be subjected to the technical problem that unnecessary noise disturbs, the utility model spy provides a kind of microphone collection sound protective cover.
For achieving the above object; microphone collection sound protective cover of the present utility model; mainly constituted by a ringwise cover body; the inner formation one of cover body is installed with the space; to be covered with microphone assembly, the place offers a circular sound collecting hole in the middle of the cover body end face, in addition; be equipped with several equally spaced flanges at the cover body peripheral region near the bottom surface, each flange also is provided with the flexible contact arm of tool to same end extension respectively.So after microphone collection sound protective cover was covered with microphone assembly, outside source of sound can be earlier by sound collecting hole, and be gathered in being installed with in the space of cover body, be passed to microphone assembly again.
As mentioned above, the utility model gathers the audio fruit by this microphone collection sound protective cover to reach, and isolates unnecessary noise intruder.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
In the utility model; microphone collection sound protective cover 10 is installed on mobile phone or the consumption electronic products such as PDA or MP3; following examples are example with the mobile phone; microphone collection sound protective cover 10 is installed on the mobile phone; and be covered with microphone assembly 20; and microphone assembly 20 is to be installed in the microphone connector 30, and microphone connector 30 is (as shown in Figure 4) on the printed circuit board (PCB) 40 in the solid welding mobile phone again.
Please refer to shown in Fig. 1,2; microphone collection sound protective cover 10 mainly is made of a ringwise cover body 1; cover body 1 inner formation one is installed with space 11; to be covered with microphone assembly 20; the place offers a circular sound collecting hole 12 in the middle of cover body 1 end face; in addition, be equipped with several equally spaced flanges 13 at cover body 1 peripheral region near the bottom surface, each flange 13 also is provided with the flexible contact arm 14 of tool to same end extension respectively.
Please refer to shown in Figure 3; this microphone collection sound protective cover 10 is when being covered with microphone assembly 20; be provided with lock structure between microphone collection sound protective cover 10 and the printed circuit board (PCB) 40; for example; the convex fastening plate 401 that is provided with in the appropriate position of printed circuit board (PCB) 40; fastening plate 401 slightly is the shape of falling L and forms an engaging space 402; after making microphone collection sound protective cover 10 be covered with microphone assembly 20; again to a sideway swivel; the flange 13 of cover body 1 bottom surface is screwed in the engaging space 402 of fastening plate 401, microphone collection sound protective cover 10 is fixed on the printed circuit board (PCB) 40.And for flange 13 can be screwed in the engaging space 402 of fastening plate 401 very smoothly, now the other end that corresponds to contact arm 14 at flange 13 is formed with a downward-sloping guide ramp 15, can be guided very smoothly in order to flange 13 to screw in to the engaging space 402 of fastening plate 401.
