Abstract
The utility model relates to a windproof microphone, comprising a housing (1). A sealing plate (10) is arranged on one end of the housing (1) and is provided with an external soniferous hole (11). A circuit board (9) is arranged in the housing (1). A pole head capacitor consisting of a vibrating film sheet (2) and a back pole plate (3) is arranged between the circuit board (9) and the sealing plate (10). A windproof sheet (4) is arranged between the sealing plate (10) and the vibrating film sheet (2). A gap (12) is mounted between the windproof sheet (4) and the sealing plate (10). Windproof-sheet soniferous holes (41) are disposed on the wind-proof sheet (4) and are staggered with the external soniferous hole (11). The external soniferous hole (11) is communicated with the windproof-sheet soniferous holes (41) through the gap (12). Compared with conventional electret capacitance-type microphones, the microphone has excellent windproof ability and the wind noise is lower than that of the conventional microphones more than 10 dB.
Description
[technical field]
The utility model relates to a kind of windproof microphone.
[background technology]
Present communication class equipment is mobile phone for example, the microphone that uses mostly is electret capcitor microphone, this type of microphone construction is simple, volume is little, performance is good, communication class product universal played very large effect, and present electret capcitor microphone design is ripe, but the user is when using communication apparatus, at some in particular cases, for example blow hard, drive motorcycle, will allow the other side hear sharp-pointed sound of the wind, affect communication effect, people sometimes even can't not hear the other side what is being said experience based on this type of user, need the design of improvement electret capcitor microphone.
[utility model content]
The utility model has overcome the deficiency of above-mentioned technology, and a kind of windproof microphone is provided, and this microphone is compared common electret capcitor microphone and compared and have good capability of anti-wind, and wind noise is lower more than 10 decibels than traditional microphones.
For achieving the above object, the utility model has adopted following technical proposals:
A kind of windproof microphone, include shell, end at described shell is provided with hush panel, described hush panel is provided with outer sound transmission aperture, be provided with circuit board in the described shell, between described circuit board and described hush panel, be provided with by vibrating diaphragm, the cartridge capacitor that back pole plate forms, it is characterized in that: between described hush panel and described vibrating diaphragm, be provided with windproof, be provided with the gap between described windproof and the described hush panel, described windproof is provided with the windproof sound transmission aperture that is crisscross arranged with described outer sound transmission aperture, and described outer sound transmission aperture is communicated with by described gap with described windproof sound transmission aperture.
The height in gap is less than 0.1mm as mentioned above.
Windproof sound transmission aperture is arranged on described hush panel central authorities as mentioned above, and described windproof sound hole is a plurality of, distributes ringwise around described windproof sound transmission aperture.
Windproof sound hole is 4 as mentioned above.
Windproof sound hole is narrow and grow as mentioned above, is fan-shaped.
Shell is cylindrical shape as mentioned above.
The beneficial effects of the utility model are:
1, the utility model adopts built-in windproof design, is arranged at cylinder-like shell inside with windproof, prevents that air-flow from directly acting on the vibrating diaphragm, has good capability of anti-wind;
2, have clearance space between the shell sound hole among the utility model and windproof sound hole, shell sound hole and windproof sound hole are staggered, thereby form the connected space of a bending, prevent that air-flow from directly acting on vibrating diaphragm;
The height of the clearance space that 3, forms between shell sound hole and the windproof sound hole slows down air-flow velocity less than 0.1mm, weakens the percussion to vibrating diaphragm.
4, windproof sound hole is a plurality of, distributes ringwise, and windproof sound hole is narrow and grow, and is fan-shaped, slows down air-flow velocity, but the acoustic pressure size is not affected, and does not affect microphone to the susceptibility of useful sound.

Fig. 1 is profile of the present utility model;
Fig. 2 is assembling schematic diagram of the present utility model;
Fig. 3 is explosive view of the present utility model;
Fig. 4 is the schematic diagram of windproof of the utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of windproof microphone, include shell 1, end at described shell 1 is provided with hush panel 10, described hush panel 10 is provided with outer sound transmission aperture 11, be provided with circuit board 9 in the described shell 1, between described circuit board 9 and described hush panel 10, be provided with by vibrating diaphragm 2, the cartridge capacitor that back pole plate 3 forms, between described hush panel 10 and described vibrating diaphragm 2, be provided with windproof 4, owing to adopt built-in windproof design, be arranged at cylinder-like shell 1 inside with windproof 4, prevent that air-flow from directly acting on the vibrating diaphragm 2, has good capability of anti-wind, be provided with gap 12 between described windproof 4 and the described hush panel 10, described windproof 4 is provided with the windproof sound transmission aperture 41 that is crisscross arranged with described outer sound transmission aperture 11, described outer sound transmission aperture 11 is communicated with by described gap 12 with described windproof sound transmission aperture 41, described shell sound hole 11 is staggered with described windproof sound hole 41, thereby form the space of a bending, prevent that air-flow from directly acting on vibrating diaphragm 2.。
As shown in Figure 3, in the utility model, the height in described gap 12 is less than 0.1mm, thereby slows down air-flow velocity, weakens the percussion to vibrating diaphragm 2.
As shown in Figure 4, in the utility model, described windproof sound transmission aperture 41 is arranged on described hush panel 10 central authorities, described windproof sound hole 41 is a plurality of, distribute ringwise around described windproof sound transmission aperture 41, as a kind of optimal way of the present utility model, described windproof sound hole 41 is 4.
As shown in Figure 4, in the utility model, described windproof sound hole 41 is narrow and grow, and is fan-shaped, thereby slows down air-flow velocity, but the acoustic pressure size is not affected, and does not affect microphone to the susceptibility of useful sound.
As shown in Figure 3, in the utility model, described shell 1 is cylindrical shape, and good looking appearance is convenient to the propagation of sound.
