The casing 10 also includes the connection front operatic tunes 110 and extraneous sound channel 30.30 shape of the sound channel
Into in the receiving space in the casing 10.The inwall 31 for surrounding the sound channel 30 is formed in the casing 10, it is described interior
31 both ends open of wall, one end form the through hole 310 connected with the front operatic tunes 110, and the other end is formed through the casing 10 and connected
Lead to the sound channel 30 and extraneous sound mouth 312, the sound mouth 312 is just to the through hole 310.The inwall 31 includes
Parallel to vibrating diaphragm 21 go out sound diapire 313, along go out that 313 two ends of sound diapire are bent to form in the same direction go out sound side wall 311 and with institute
The cover plate 314 that connects of lid of side wall 311 is stated, is gone out sound diapire 313 and is gone out sound side wall 311 and form an opening, cover plate 314 covers the opening
End, thus the cover plate 314 goes out sound side wall 311 and to go out sound diapire 313 and surround the sound channel 30 with described.
The casing 10 also includes the multiple baffle plates 50 for interlocking and being spaced being placed in the sound channel 30.The baffle plate
50 are included from going out two first baffles 51 that sound side wall 311 is extended in parallel towards offside described in homonymy, and from the diapire
3112 second baffles 53 extended towards the cover plate 314.The first baffle 51 is preset with sound side wall 311 is gone out described in offside
Gap, and the first baffle 51 is equal with the distance between sound side wall 311 is gone out described in offside；The second baffle 53 is folded in
Between the two neighboring first baffle 51,53 two ends of the second baffle respectively with it is described go out 311 interval setting of sound side wall, and
The two ends of the second baffle 53 with it is described go out the distance between sound side wall 311 it is unequal.The first baffle 51 and described
Two baffle plates 53 also be arranged in parallel.
This utility model also provides the microphone device 200 of second embodiment, and which includes casing 40 and loudspeaker monomer (figure
Do not show), casing 40 includes sound channel 70 and the multiple baffle plates 80 in sound channel 70, its structure and first embodiment
Microphone device 100 it is substantially similar, difference is：
The sound mouth 712 and the through hole 710 stagger setting, and the inwall 71 also includes separating the front operatic tunes (figure
Do not mark) with the first connection wall 713 of the sound channel 70, and along it is described go out sound side wall 711 away from the one of the front operatic tunes

With 715 interval setting of first connection wall 713 and the second connection wall, and the two ends of the fourth gear plate 83 and the first connection wall
713 is unequal with the distance between second connection wall 715.
If λ is wavelength, f is frequency, and c is 340 meter per second of the velocity of sound, and n is natural number, λ f=c, as 2*y1=λ/2* (2n+1)
When, for the sound wave with λ wavelength for passing through from the two ends of the two ends of the second baffle 53 or the fourth gear plate 83 respectively
180 ° of phase, so as to reach the selectivity soundproof effect to multiple frequency ranges.Before this structure partly can increase simultaneously
The length of the sound channel 30,70, can partly increase acoustic resistance, can also increase the absorption to radio-frequency component and noise and imitate
Really.Normally due to survey pronunciation box sizes are limited, and low-frequency sound wave is very long, therefore this soundproof effect will not be main to low frequency etc.
Working frequency range is produced a very large impact.Therefore, using the structure optionally can reduce high-frequency resonant peak and other high frequencies into
Point, reaching improves the effect of audition.
The microphone device of one end open is compared using the structure of this utility model embodiment, selective absorbing can be increased
Band limits, can increase to each frequency range acoustically effective.Multiple baffle plates 50,80 are compared to the knot for only arranging a baffle plate
Structure, as multiple baffle plates 50,80 can absorb repeatedly, can increase acoustically effective.
It is appreciated that the baffle plate 50,80 shapes, quantity and bearing of trend are unrestricted, such as alternatively circular plate-like shape, can
For three, four or other quantity, as long as stagger being arranged in sound channel 30,70.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in
Other related technical fields, are included in scope of patent protection of the present utility model in the same manner.
