Description
Technical field
The utility model relates to the microphone products technical field, particularly a kind ofly reduces 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 of certain slowing down vibration, with hand or the face that reduces due to the user, with microphone, contact the friction noise that produces.
Development along with electronic technology, mobile phone and some earphones with pick up facility had obtained 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 on the impact of microphone tonequality, yet with the mode that the increase gum cover reduces friction noise, does not have at all and reduce the effect that wind is made an uproar in prior art.
The utility model content
Technical problem to be solved in the utility model is to provide 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, the technical solution of the utility model 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 the first through holes, and the other end of described coupling cavity is provided be used to being communicated with the second through hole of 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 described coupling cavity back cover, and described the second through hole is positioned on described coupling cavity fore shell.
Wherein, on described coupling cavity fore shell, the position of corresponding described the second through hole is provided with into part spare, and described sound hole is positioned at the described end of advancing part spare.
Wherein, describedly advance the described sound hole of the part spare uncovered formation of 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 the second through hole.
Wherein, described the first through hole and described third through-hole are crisscross arranged.
Wherein, the inwall of described gum cover is provided with the first boss and second boss of annular, and described microphone monomer is between described the first boss and the second boss, and described coupling cavity back cover is overlapped on described the first boss.
Wherein, the gross area of each described the first through hole is 1mm
2.
As a kind of execution mode, in described coupling cavity, be filled with the sound-absorbing medium.
After having adopted technique scheme, the beneficial effects of the utility model are:
The microphone monomer outside that reduces the operatic tunes structure that microphone pickup wind makes an uproar due to the utility model 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 the first through holes, and the other end of coupling cavity is provided be used to being communicated with the second through hole of 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 the 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, only have stronger voice signal could touch by the first through hole the pickup face of microphone monomer, make the vibrating diaphragm of microphone monomer produce vibration, be converted into the signal of telecommunication.Thereby effectively reduce the impact of outdoor sound of the wind on microphone tonequality, experiment records and can reduce wind and make an uproar and reach 10dB, effectively raises the sound quality of microphone.
Owing to advancing part spare, be provided with some third through-holes, the voice signal that sound hole is come in first through advance part spare stop the shunting with third through-hole after just can enter in the coupling cavity, played the effect that certain reduction wind is made an uproar; Due to third through-hole and the first through hole, be crisscross arranged again, prevented that effectively air-flow that wind produces from directly arriving the pickup face of microphone, air-flow could arrive the pickup face of microphone after weakening through the buffering of coupling cavity in the coupling cavity, the wind noise cancellation signal has been played to further attenuation, further improved the sound quality of microphone.
Owing in the coupling cavity, being 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, the sound such as outdoor sound of the wind, automobile contain the high frequency composition, therefore 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 after the sound-absorbing medium and can reduce wind and make an uproar and reach 25dB.
In sum, the utility model reduces operatic tunes structure that microphone pickup wind makes an uproar, and to have solved in prior art the impact of making an uproar of microphone wind-engaging outstanding, the technical problem that sound quality is poor.The operatic tunes structure that the utility model reduction microphone pickup wind is made an uproar effectively reduces wind and makes an uproar, and has improved the sound quality of microphone.
