Description
Technical field
The present invention relates to the microphone products technical field, particularly a kind ofly reduce the operatic tunes structure that microphone pickup wind is made an uproar.
Background technology
Microphone is a kind of pick up facility, is the energy converter that the voice signal that will be transmitted by sound hole is converted to the signal of telecommunication.Traditional microphone is at simple gum cover of the outside of microphone monomer suit, the shell of microphone monomer and microphone is isolated, reach the effect that necessarily slows down vibration, contact the friction noise that produces with microphone with hand or the face that reduces owing to the user.
Along with development of electronic technology, the earphone that mobile phone and some have pick up facility had got universal widely, microphone as pick up facility inevitably is installed in these electronic products, and the applicable situation of these electronic products is more various, and mostly is the more noisy open air of environment.Outdoor sound of the wind is particularly outstanding to the influence of microphone tonequality, yet the mode that reduces friction noise with the increase gum cover in the prior art does not have at all and reduces the effect that wind is made an uproar.
Summary of the invention
Technical problem to be solved by this invention provides a kind of operatic tunes structure that microphone pickup wind is made an uproar that reduces, and the operatic tunes structure that this reduction microphone pickup wind is made an uproar can effectively reduce wind and make an uproar, and has improved the sound quality of microphone.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind ofly reduce the operatic tunes structure that microphone pickup wind is made an uproar, comprise the microphone monomer, the described microphone monomer outside is set with gum cover, described operatic tunes structure also comprises a coupling cavity, the part of described coupling cavity is positioned at described gum cover, and the end that described coupling cavity body is positioned at described gum cover is provided with at least two first through holes, and the other end of described coupling cavity is provided with for second through hole that is communicated with sound hole.
Wherein, described coupling cavity comprises coupling cavity fore shell and the coupling cavity back cover that is combined as a whole; Each described first through hole is positioned on the described coupling cavity back cover, and described second through hole is positioned on the described coupling cavity fore shell.
Wherein, the position of corresponding described second through hole is provided with into part spare on the described coupling cavity fore shell, and described sound hole is positioned at the described end of advancing part spare.
Wherein, describedly advance the described sound hole of the uncovered formation of part spare one end, the described other end that advances part spare is provided with the third through-hole of the described sound hole of some connections and described second through hole.
Wherein, described first through hole and described third through-hole are crisscross arranged.
Wherein, the inwall of described gum cover is provided with first boss and second boss of annular, and described microphone monomer is between described first boss and second boss, and described coupling cavity back cover is overlapped on described first boss.
Wherein, the gross area of each described first through hole is 1mm
2
As a kind of execution mode, be filled with the sound-absorbing medium in the described coupling cavity.
After having adopted technique scheme, the invention has the beneficial effects as follows:
Because reducing the microphone monomer outside of the operatic tunes structure that microphone pickup wind makes an uproar, the present invention is set with gum cover, one end of gum cover is provided with the coupling cavity, the end that the coupling cavity body is positioned at gum cover is provided with at least two first through holes, and the other end of coupling cavity is provided with for second through hole that is communicated with sound hole.The voice signal that sound hole is come in that is arranged so that of coupling cavity and coupling cavity end of body first through hole has obtained buffering in the coupling cavity, the sound of the wind that intensity is less and other noise signal are attenuated disappearance in the coupling cavity, have only stronger voice signal could touch the pickup face of microphone monomer by first through hole, make the vibrating diaphragm of microphone monomer produce vibration, be converted into the signal of telecommunication.Thereby effectively reduced outdoor sound of the wind to the influence of microphone tonequality, experiment records and can reduce wind and make an uproar and reach 10dB, effectively raises the sound quality of microphone.
Owing to advance part spare and be provided with some third through-holes, the voice signal that sound hole is come in through earlier advancing part spare stop shunting with third through-hole after just can enter in the coupling cavity, played the effect that certain reduction wind is made an uproar; Again since third through-hole and first through hole be crisscross arranged, prevented that effectively air-flow that wind produces from directly arriving the pickup face of microphone, could arrive the pickup face of microphone after the buffering of air-flow process coupling cavity weakens in the coupling cavity, the wind noise cancellation signal is played further attenuation, further improved the sound quality of microphone.
Owing in the coupling cavity, be filled with the sound-absorbing medium.The sound-absorbing medium is better to the acoustic absorption effect of intermediate frequency or high frequency, people's sound belongs to low-frequency sound, sound such as outdoor sound of the wind, automobile contain the high frequency composition, so after filling in the sound-absorbing medium, can better absorb wind makes an uproar, improve the sound quality of microphone, experiment records to fill in and can reduce wind behind the sound-absorbing medium and make an uproar and reach 25dB.
In sum, the present invention reduces operatic tunes structure that microphone pickup wind makes an uproar, and to have solved in the prior art influence of making an uproar of microphone wind-engaging outstanding, the technical problem of sound quality difference.The present invention reduces operatic tunes structure that microphone pickup wind makes an uproar and has effectively reduced wind and make an uproar, and has improved the sound quality of microphone.
