Background technology
The U of patent CN 202455520 describe a kind of waterproof construction with microphone apparatus, and the program is in packing element pad and shell
Internal surface（Jacket casing bottom）Between be provided with waterproof membrane.Because waterproof membrane is general all than relatively thin, waterproof membrane is placed on by one
Easily waterproof membrane is wrinkled during jacket casing bottom, if secondly when packing element pad is expressed to waterproof membrane, because packing element pad is squeezed
Its bottom is deformed wrinkling waterproof membrane, so as to influence waterproof and make audio distortions；If packing element pad is not expressed to waterproof membrane,
Then have influence on waterproof effect.The program solves the problems, such as air-tightness by being provided with marine glue sealing in microphone rearward end,
Illustrate the problem of it sets waterproof membrane to can't resolve air-tightness between the inner surface and packing element pad of housing.
Utility model content
The purpose of this utility model is between a kind of microphone of design and apparatus casing, reaches i.e. waterproof and can and passes through air-tightness
Detect and do not make the waterproof construction with microphone apparatus of audio distortions.
What technical solutions of the utility model were realized in：A kind of waterproof construction with microphone apparatus, including equipment
Housing and microphone, housing correspond to and penetrable sound hole are offered at the pickup hole of microphone, and pickup hole face is to penetrable sound hole, shell inner surface
Surrounding's disjunctor of penetrable sound hole has a jacket casing, in jacket casing interference be embedded with a packing element pad, be provided with first through hole in packing element pad, this
One through hole aligns with penetrable sound hole, is provided with microphone above first through hole, the shell inner surface of packing element pad and jacket casing bottom it
Between be provided with a waterproof membrane, plate is additionally provided between waterproof membrane and packing element pad, is provided with the second through hole on plate, second through hole with
Penetrable sound hole is alignd, and the bottom surface of packing element pad is squeezed on the upper surface of plate.
Preferably：Counterbore is provided with above first through hole, counterbore is alignd with penetrable sound hole, and microphone interference is embedded in counterbore
It is interior.
Preferably：Waterproof membrane is bonded on the lower surface of plate.
Preferably：Packing element pad is made by non-hydrophilic latex or rubber.
Preferably：Waterproof membrane is made by rubber.
Beneficial effect：The utility model is simple in construction, cost is low, has reached the effect that i.e. waterproof keeps sound quality again,
And the waterproof construction can pass through air-leakage test.

Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
First embodiment as shown in Figure 1.A kind of waterproof construction with microphone apparatus, including the housing 1 of equipment, Mike
Wind 10.Housing 1 offers penetrable sound hole 2 in the corresponding position with the pickup hole of microphone 10, and pickup hole is alignd with penetrable sound hole 2 and pickup hole
Towards penetrable sound hole.Surrounding's disjunctor of the inner surface penetrable sound hole 2 of housing 1 is provided with a jacket casing 5, i.e., the bottom of jacket casing 5 and housing 1 is interior
Surface is connected or jacket casing 5 is integrally formed with housing 1.The bottom of jacket casing 5（I.e. at the inner surface penetrable sound hole 2 of housing 1）Set
There is a waterproof membrane 3, the top of waterproof membrane 3 is provided with a plate 4, and the size of plate 4 is consistent with the size of waterproof membrane 3.Plate 4
Centre be provided with the second through hole 9, the second through hole 9 aligns with penetrable sound hole 2.Waterproof membrane 3 is bonded on the lower surface of plate 4.
When installing the waterproof construction, first waterproof membrane 3 is bonded on the lower surface of plate 4, then by plate 4 and the combination of waterproof membrane 3
The bottom of jacket casing 5 is together placed on, and waterproof membrane 3 is faced penetrable sound hole, so can ensure that waterproof membrane 3 when mounted will not
Corrugation, so as to ensure the water resistance of the waterproof construction and keep the quality of sound.Interference is embedded in the jacket casing 5 of the top of plate 4
There is a packing element pad 6.The bottom surface of packing element pad 6 is squeezed on the upper surface of plate 4, thus can be by padding 6 bottom surfaces from packing element
Extruding force makes the waterproof membrane 3 of the lower section of plate 4 be fitted in completely on the inner surface of housing 1, the inner surface crush seal of plate 4 and housing 1,
Avoid gas leakage and leak so that without ventilative gap between penetrable sound hole 2 and plate 4, ensure that the air-tightness of the waterproof construction.Packing element pad
Be provided with first through hole 7 in 6, the top of first through hole 7 is provided with microphone 10, pickup hole, first through hole 7, the second through hole 9 with
Penetrable sound hole 2 on housing aligns.Outside sound sequentially passes through penetrable sound hole 2, waterproof membrane 3, the second through hole 9, first through hole 7, picked up
Sound hole enters in microphone 10.Packing element pad 6 is made by non-hydrophilic latex or rubber.Waterproof membrane 3 is made by rubber.
Second embodiment as shown in Figure 2.The top of first through hole 7 is provided with a counterbore 8, and counterbore 8 is located in packing element pad 6
Top, first through hole 7 is located at the bottom in packing element pad 6.Counterbore 8 aligns with penetrable sound hole 2.Microphone interference is embedded in counterbore 8
It is interior and positive towards penetrable sound hole 2, keep pickup hole to be alignd with penetrable sound hole 2.
