The basic device that microphone is talked with as man-machine language, its application field and application scenarios are also more and more wider.Traditional structure
Microphone, including substrate, the shell of receiving space is formed with substrate, the microphone chip and integrated electricity being arranged in receiving space
Road chip, wherein shell are flat configuration, it is necessary to additionally add the auxiliary knots such as Air Filter, gum cover in the practical application of microphone
Structure is closely to equip microphone and terminal device, but the structure such as increased Air Filter, gum cover makes Product Assembly complicated, reliability
It is relatively low, easily produce microphone come off, sealing difference the problems such as, bring very big inconvenience to microphone applications.
Therefore, it is necessary to provide a kind of new microphone structure, the defects of to overcome conventional microphone.
Utility model content
A purpose of the present utility model is to provide a kind of reliability height, the strong microphone of structural stability.
In order to realize above technical purpose, a kind of microphone of the utility model uses following technical scheme：
A kind of microphone, including substrate, the encapsulating structure of receiving space is formed with the substrate, it is empty to be arranged at the collecting
In microphone chip and IC chip, be provided with sound hole on the encapsulating structure, the encapsulating structure corresponds to institute
State sound hole and be provided with extension, the sound hole is corresponded in the extension and is provided with into sound passage.
As a kind of perferred technical scheme, the extension is cylindrical structural, is set inside the cylindrical structural
Enter sound passage also for cylinder.
As a kind of further preferred technical scheme, the internal diameter that the cylinder enters sound passage is 0.1mm to 50mm.
As another preferable technical scheme, the extension is highly 0.2mm to 50mm.
As another preferable technical scheme, the one end of the extension away from the encapsulating structure is additionally provided with and institute
State the vertical limiting section of extension.
As a kind of further preferred technical scheme, positioned at the encapsulating structure and described spacing on the outside of the extension
Position between portion is provided with O-ring.
A kind of microphone of the present utility model, the position that sound hole is corresponded in outside encapsulating structure are provided with extension, should
Extension can be directly embedded into end product shell and realize assembling, improve the fastness that is combined with end product shell of microphone and close
Feng Xing, meanwhile, extension is provided with the normal work entered sound passage, ensure microphone being passed to for external sound.This practicality is new
The microphone structure of type makes microphone applications easier, and assembly technology is saved when terminal is assembled and improves efficiency of assembling, simultaneously
Ensure the reliability and structural stability of microphone, be advantageous to the large-scale application of microphone products, be improved particularly microphone and exist
Reliability and stability when industry and automotive field are applied.
Brief description of the drawings
The accompanying drawing of a part for constitution instruction describes embodiment of the present utility model, and uses together with the description
In explanation principle of the present utility model.
Fig. 1 is a kind of structural representation of microphone embodiment one of the utility model

Embodiment
Various exemplary embodiments of the present utility model are described in detail now with reference to accompanying drawing.It should be noted that：It is unless another
Illustrate outside, the part and the positioned opposite of step, numerical expression and numerical value otherwise illustrated in these embodiments is unlimited
The scope of the utility model processed.
The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below
New and its application or any restrictions used.
It may be not discussed in detail for technology and equipment known to person of ordinary skill in the relevant, but in appropriate situation
Under, the technology and equipment should be considered as part for specification.
In shown here and discussion all examples, any occurrence should be construed as merely exemplary, without
It is as limitation.Therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following accompanying drawing, therefore, once a certain Xiang Yi
It is defined, then it need not be further discussed in subsequent accompanying drawing in individual accompanying drawing.
Embodiment one：
As shown in figure 1, the microphone of the present embodiment, including substrate 1, the encapsulating structure 2 with the formation receiving space of substrate 1,
The microphone chip 3 and IC chip 4 being arranged in the receiving space, it is provided with for external sound on encapsulating structure 2
Incident sound hole, the corresponding sound hole of encapsulating structure 2 are provided with extension 2a, sound hole are corresponded in extension 2a and is provided with into sound
Passage with ensure external sound incidence.Extension 2a, can be directly embedding when the microphone applications of the present embodiment are in end product
Enter the shell of end product and combine closely, without other annexes such as gum cover are added, reduce assembly difficulty, improve terminal device
Packaging efficiency, be advantageous to the large-scale application of microphone products, meanwhile, extension 2a is effectively ensured microphone and filled in end product
Reliability and structural stability after matching somebody with somebody.
In actual applications, the preferably cylindrical structures of extension 2a, the sound passage that enters that extension 2a inside is set also are
Cylinder.The internal diameter that the cylinder enters sound passage is 0.1mm to 50mm, ensures that sound is incident.
