Abstract
The invention relates to a wind-proof microphone. The wind-proof microphone comprises a shell (1), wherein a sealing plate (10) is arranged at one end of the shell (1) and provided with an external soniferous hole (11); a circuit board (9) is arranged in the shell (1); a pole head capacitor consists of a vibrating diaphragm (2) as well as a backplate (3), and is arranged between the circuit board (9) and the sealing plate (10); a wind-proof sheet (4) is arranged between the sealing plate (10) and the vibrating diaphragm (2); a gap (12) is reserved between the wind-proof sheet (4) and the sealing plate (10); a wind-proof sheet soniferous hole (41) is formed on the wind-proof sheet (4) and interleaved with the external soniferous hole (11); and the external soniferous hole (11) is communicated with the wind-proof sheet soniferous hole (41) through the gap (12). Compared with a conventional electret condenser microphone, the microphone provided by the invention has an excellent wind-proof capacity, and the wind noise ratio is more than 10 dB lower than that of the conventional microphone.
Description
[technical field]
The present invention relates to a kind of windproof microphone.
[background technology]
Present communication class equipment is mobile phone for example, and the microphone of use mostly is an electret capcitor microphone, and this type of microphone construction is simple, and volume is little; Performance is good, to universal very big effect, the present electret capcitor microphone design maturation of having played of communication class product; But the user at some in particular cases, is for example blown hard when using communication apparatus; Drive motorcycle, will let the other side hear sharp-pointed sound of the wind, influence communication effect; People sometimes even can't not hear the other side what is being said based on this type of user experience, need the design of improvement electret capcitor microphone.
[summary of the invention]
The present invention has overcome the deficiency of above-mentioned technology, and 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 realizing above-mentioned purpose, the present invention has adopted following technical proposals:
Windproof microphone; Include shell, be provided with hush panel at an end of said shell, described hush panel is provided with outer sound transmission aperture; Be provided with circuit board in the described shell; Between said circuit board and described hush panel, be provided with the cartridge capacitor of forming by vibrating diaphragm, back pole plate, it is characterized in that: between said hush panel and said vibrating diaphragm, be provided with windproof, be provided with the gap between said windproof and the described hush panel; Said windproof is provided with the windproof sound transmission aperture that is crisscross arranged with said outer sound transmission aperture, and said outer sound transmission aperture is communicated with through said gap with said windproof sound transmission aperture.
The height in gap is less than 0.1mm as stated.
It is central that a windproof as stated sound transmission aperture is arranged on said hush panel, and said windproof sound hole is a plurality of, distributes ringwise around described windproof sound transmission aperture.
Windproof as stated sound hole is 4.
Windproof as stated sound hole is narrow and grow, and is fan-shaped.
Shell is a cylindrical shape as stated.
The invention has the beneficial effects as follows:
1, the present invention 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 present invention and windproof sound hole, the arrangement of staggering of shell sound hole and windproof sound hole, thus 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 influenced, and does not influence the susceptibility of microphone to useful sound.
[description of drawings]
Fig. 1 is a profile of the present invention;
Fig. 2 is an assembling sketch map of the present invention;
Fig. 3 is an explosive view of the present invention;
Fig. 4 is windproof of the present invention's a sketch map.
[embodiment]
Below in conjunction with accompanying drawing the present invention is done further detailed description.
Like Fig. 1, Fig. 2, shown in Figure 3, windproof microphone includes shell 1; End at said shell 1 is provided with hush panel 10, and described hush panel 10 is provided with outer sound transmission aperture 11, is provided with circuit board 9 in the described shell 1; Between said circuit board 9 and described hush panel 10, be provided with the cartridge capacitor of forming by vibrating diaphragm 2, back pole plate 3; Between said hush panel 10 and said vibrating diaphragm 2, be provided with windproof 4,, be arranged at cylinder-like shell 1 inside windproof 4 owing to adopt built-in windproof design; Prevent that air-flow from directly acting on the vibrating diaphragm 2; Have good capability of anti-wind, be provided with gap 12 between said windproof 4 and the described hush panel 10, said windproof 4 is provided with the windproof sound transmission aperture 41 that is crisscross arranged with said outer sound transmission aperture 11; Said outer sound transmission aperture 11 is communicated with through said gap 12 with said windproof sound transmission aperture 41; The arrangement of staggering of said shell sound hole 11 and said windproof sound hole 41, thus the space of a bending formed, prevent that air-flow from directly acting on vibrating diaphragm 2.。
As shown in Figure 3, in the present invention, the height in said 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 present invention, said windproof sound transmission aperture 41 is arranged on said hush panel 10 central authorities; Said 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 invention, said windproof sound hole 41 is 4.
As shown in Figure 4, in the present invention, said 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 influenced, and does not influence the susceptibility of microphone to useful sound.
As shown in Figure 3, in the present invention, said shell 1 is a cylindrical shape, and good looking appearance is convenient to the propagation of sound.
