Two split channels, this two split channel head ends are connected with each other, and tail end is connected with each other and is directed towards, and the sound hole is connected to
At the head end interconnection of two split channels, the tail end that the microphone mounting hole is connected to two split channels is connected with each other
Place.
Preferably, the tail end of two split channels is mutually aligned.
Preferably, the shunting structure that liquidates further includes inlet channel by the head end phase of sound hole and two split channels
Connect place's connection, and the side wall of the sound hole alignment inlet channel is to form turning.
Preferably, the angle at the turning that the sound hole and inlet channel are formed is 90 °.
Preferably, the structure that liquidates that shunts includes the busway with turning, the busway connection microphone peace
At the tail end interconnection for filling hole and two split channels.
Preferably, the angle at the turning of the busway is 90 °.
Preferably, the length of first split channel and the second split channel is identical.
Preferably, the cross section of first split channel and the second split channel is identical.
Preferably, first split channel and the second split channel are symmetrical.
The utility model has the following beneficial effects: the rough air or the extraneous disturbance gas blown over that are breathed out when user speaks
After stream enters sound hole, punishment is connected with each other into two-way in the head end of two split channels, two-way rough air passes through two respectively
After split channel, to converge at the tail end interconnection of two split channels, two-way rough air reverse phase liquidates when converging, from
And the air quantity for weakening rough air even completely eliminates rough air, such rough air would not be installed with microphone is mounted on
Ear microphone friction in hole generates wind and makes an uproar.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that structure is eliminated for the rough air of ear microphone；
Fig. 2 is the explosive view that structure is eliminated for the rough air of ear microphone.
Description of symbols: 1- shell；2- shunts the structure that liquidates；3- microphone mounting structure；11- sound hole；21- air inlet

Specific embodiment
Rough air for ear microphone eliminates the structural schematic diagram of structure as shown in Figure 1, being used for ear microphone
Rough air eliminate structure and include shell 1, shunt and liquidate structure 2 and microphone mounting structure 3, shell 1 is equipped with sound hole
11.Rough air for ear microphone is eliminated the explosive view of structure and is led to as shown in Fig. 2, shunting the structure 2 that liquidates including air inlet
Road 21, the first split channel 22, the second split channel 23 and busway 24, wherein the first split channel 22 and the second shunting are logical
Symmetrically, the head end of the head end of the first split channel 22 and the second split channel 23 is connected with each other, the first split channel in road 23
The tail end of 22 tail end and the second split channel 23 is connected with each other, and the tail end of two of them split channel 22,23 is mutually aligned.Into
21 one end of gas channel connects sound hole 11, and the other end connects at the head end interconnection of two shunt conduits 22,23, and sound hole
The side wall of 11 alignment inlet channels 21, so that forming a turning between sound hole 11 and inlet channel 21, which is preferably
90°.Microphone mounting structure 3 is equipped with microphone mounting hole 31 to be inserted into installation for ear microphone (not shown), converges
24 one end of circulation road connects microphone mounting hole 31, and the other end connects at the tail end interconnection of two shunt conduits 22,23.It converges
Circulation road 24 is equipped with turning, which is preferably 90 °, so that busway 24 is worn after shunting liquidates and extends one section in structure 2
The shunting structure 2 that liquidates is crossed to turn to microphone mounting hole 31.
When user speaks against sound hole 11, the rough air of user's exhalation or the extraneous rough air blown over are from sound hole
11 enter the inlet channel 21 for shunting the structure 2 that liquidates, in the process, due to being formed between sound hole 11 and inlet channel 21
One turning, rough air can tentatively weaken in the joint of sound hole 11 and inlet channel 21.Disturbance gas after preliminary decrease
Stream is come at the head end interconnection of two shunt conduits 22,23 by inlet channel 21, the head end be connected with each other punishment at
Two-way, this two-way rough air respectively enter the first shunt conduit 22 and the second shunt conduit 23.It is shunted passing through first respectively
After pipeline 22 and the second shunt conduit 23, two-way rough air converges at the tail end interconnection of two shunt conduits 22,23
It closes, two-way rough air reverse phase liquidates when converging, so that the air quantity for greatly weakening rough air even completely eliminates disturbance gas
Stream.If two-way rough air is not completely eliminated when converging, remaining rough air intensity is also very faint, remaining faint
Rough air also can further weaken when by the turning of busway 24, and faint rough air is basic after further weakening
On be completely eliminated, such rough air just substantially will not enter microphone mounting hole 31 in microphone rub generate wind
It makes an uproar.
In the present embodiment, length, the cross section size of the first split channel 22 be equal to the length of the second split channel 23,
Cross section size, such two-way rough air is respectively after two split channels 22,23, in two split channels 22,23
Air quantity is essentially identical when tail end converges, and such two-way rough air can more fully carry out reverse phase and liquidate, to fully subtract
The air quantity of weak disturbance air-flow, even completely eliminates rough air.
