Technical field
The present invention relates to reduce noise device technique field, be specifically related to a kind ofly can reduce the microphone apparatus that wind is made an uproar.
Background technology
Occasion at high-speed motion; Like automobile, motorcycle etc.; The DV machine take and recording in, receive the air-flow of high-speed motion easily and produce wind and make an uproar, influenced user's daily use; The formation that wind is made an uproar mainly comprises several aspects; The one, the eddy current noise that around DV equipment, produces, the 2nd, thus high speed winds impact equipment itself causes vibrating the noise of generation, and the 3rd, the noise of the eddy current that wind is located to produce at tone-entering hole (like the recording hole of microphone); The first two plant wind make an uproar main solution at present be change equipment itself Streamline Design with increase cushion and wait and reduce eddy current wind and make an uproar and vibrate wind and make an uproar, it then is a difficult problem that solves in the prior art that the wind of tone-entering hole place eddy current generation is made an uproar.
The patent No. be 20092022496.7 utility model patent a kind of microphone disclosed the wind erecting device of making an uproar falls; Be arranged between uni-directional microphone and the electronic product; It utilizes the porous denoising device can eliminate the electronic product wind influence of making an uproar in use, adopts fixedly uni-directional microphone position that sound point is into still fixed before and after uni-directional microphone of microphone pedestal; Positioning tube can also play the effect of isolates sound except the effect that reaches the location, both reduces wind and makes an uproar thereby reach, and does not influence the effect of sensitivity again.Its product is mainly used in occasions such as earphone or bluetooth earphone, because its microphone place wind speed is not high, the wind that falls of design is made an uproar also simple relatively.
Thereby relative technical staff, need to design the microphone apparatus that a kind of wind that can reduce microphone tone-entering hole place in the occasion of high-speed motion is made an uproar, solve the deficiency of prior art.
Summary of the invention
The technical problem that the present invention will solve provides microphone that a kind of wind that can reduce the tone-entering hole place makes an uproar and falls the wind device of making an uproar.
In order to solve technical problem set forth above, the present invention adopts following technical scheme, and the wind device of making an uproar falls in a kind of microphone; Comprise fuselage, microphone, recording hole, positioning tube, said fuselage bottom is provided with intake stack, and said positioning tube is positioned at fuselage interior; Microphone is positioned at positioning tube, and said recording hole is positioned at the microphone lower end, also comprises first filler and second filler; Said first filler is positioned at positioning tube bottom inwall; The first filler biend is provided with first groove and second groove, is filled with second filler in first groove, and filter wind passage runs through first filler and connects first groove and second groove.
Preferably, the wind device of making an uproar falls in microphone of the present invention, and said intake stack is positioned on same the axis with the recording hole, and said filter wind passage is positioned on the different axis with the hole of recording.
Preferably, the wind device of making an uproar falls in microphone of the present invention, all is interference fit between said microphone and positioning tube, said first filler and positioning tube, said second filler and first groove.
Preferably, the wind device of making an uproar falls in microphone of the present invention, and said filter wind channel inner surface is rough waveform passage.
Preferably, the wind device of making an uproar falls in microphone of the present invention, and the material that said first filler is is a silica gel, and the material of said second filler is a sponge.
Preferably, the wind device of making an uproar falls in microphone of the present invention, also is provided with in said second groove and is filled with sponge.
Preferably, the wind device of making an uproar falls in microphone of the present invention, and the cross sectional shape of said first filler, second filler, first groove and second groove is circle.
Beneficial effect of the present invention is:
1, the wind device of making an uproar that falls of the present invention has simple in structure, practical, reliable;
2, high speed winds is handled through reduction of speed, the noise reduction sound of silica gel and sponge, makes the position in recording hole not have wind noise.
Description of drawings
In order to be easy to explanation, the present invention is done to describe in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is a vertical view of the present invention;
Fig. 2 is the cutaway view of the A-A direction of Fig. 1 of the present invention;
Fig. 3 is the cutaway view of the B-B direction of Fig. 1 of the present invention.
Embodiment
Referring to Fig. 1-shown in Figure 2, the present invention provides a kind of microphone to fall the wind device of making an uproar, and comprises fuselage 1, microphone 3, recording hole 6, positioning tube 7; Said fuselage 1 bottom is provided with intake stack 5, and said positioning tube 7 is positioned at fuselage 1 inside, and microphone 3 is positioned at positioning tube 7; Said recording hole 6 is positioned at microphone 3 lower ends; Also comprise first filler 2 and second filler 4, said first filler 2 is positioned at positioning tube 7 bottom inwalls, and first filler, 2 biends are provided with first groove 21 and second groove 22; Be filled with second filler 4 in first groove 21, filter wind passage 8 runs through first filler 2 and connects first groove 21 and second groove 22.Said intake stack 5 is positioned on same the axis with recording hole 6, and said filter wind passage 8 is positioned on the different axis with recording hole 6.All be interference fit between said microphone 3 and positioning tube 7, said first filler 2 and positioning tube 7, said second filler 4 and first groove 21.Said filter wind passage 8 inner surfaces are rough waveform passage.The material that said first filler 2 is is a silica gel, and the material of said second filler 4 is a sponge.Also be provided with in said second groove 22 and be filled with sponge.The cross sectional shape of said first filler 2, second filler 4, first groove 21 and second groove 22 is circle.
The DV machine is when concrete work (in the high-speed motion); High speed winds gets into first groove, 21 places through intake stack 5; Owing in first groove 21, filled the sound-absorbing sponge, high speed winds gets into filter wind passage 8 after making an uproar through the sound-absorbing of the sound-absorbing sponge in first groove 21 and suction; Because will filter wind passage 8 inner surfaces is designed to rough waveform passage, can have better cushioned the speed of high speed winds and absorb the effect that wind is made an uproar.And owing to all be interference fit between microphone 3 and positioning tube 7, first filler 2 and positioning tube 7, said second filler 4 and first groove 21, the wind speed that is not vulnerable to high speed winds in the course of the work influences and the phenomenon that occurs coming off.After the effect of wind through filter wind passage 8; Speed and wind are made an uproar and are reduced gradually, and also be provided with in second groove 22 and be filled with the sound-absorbing sponge this moment, passes through the effect of sound-absorbing sponge once more; Wind noise also and the flow velocity of wind disappear basically, reduce the effect that wind is made an uproar thereby reach.Among the present invention; During design airduct road 5 and recording hole 6 are positioned on same the axis, filter wind passage 8 is positioned on the different axis with recording hole 6, through this kind placement; The effect of right-angled bend need be passed through when high speed winds gets into, the wind speed of high speed winds can be reduced so greatly.
The embodiment of the above is a preferred embodiments of the present invention, is not to limit practical implementation scope of the present invention with this, and scope of the present invention comprises and is not limited to this embodiment.All shapes according to the present invention, the equivalence variation that structure is done all comprise in protection scope of the present invention.
