Description
【Technical field】
The utility model is related to electroacoustic transduction field, a kind of particularly microphone device.
【Background technology】
With the arrival of mobile internet era, the quantity of Intelligent mobile equipment constantly rises.And in numerous mobile devices
Among, mobile phone is undoubtedly most common, most portable mobile terminal device.Currently, the function of mobile phone is extremely various, one of them is just
It is the music function of high-quality, therefore, the microphone device for playing sound is widely applied Intelligent mobile equipment till now
Among.
However, due to the problem of being limited to cavity space after loud speaker module, it is difficult to realize the demand of acoustical behavior.In correlation
In the microphone device of technology, the prior art has in back cavity filling sound-absorbing material, raising acoustical behavior, but sounding monomer and cover board
Between always have a fit-up gap, fill other materials, have lost segment space, prevent performance from reaching ultimate attainment, there is also product
The problem of shell shake (caused shell resonance when working of sounding monomer).In order to solve the shake of product shell and efficiently use rear cavity space
Between, usually in the gap filling buffer substance (such as glue or buffering foam etc.), fill part back cavity volume is understood in this way, is existed
The gluing position part in cavity space can not utilize afterwards, thereby result in the loss in acoustical behavior.In order to efficiently use rear cavity space
Between while, avoid product shell from shaking and improve the low frequency performance of microphone device, therefore, it is necessary to provide a kind of new acoustical generator
Part.
【Utility model content】
To solve the above-mentioned problems, the utility model provides a kind of microphone device comprising the shell with receiving space
The receiving space is separated into ante-chamber and back cavity by body and the sounding monomer being contained in the shell, the sounding monomer, institute
Stating when the inhibition sounding monomer for being equipped with and being located between the sounding monomer and the shell in back cavity works causes shell to resonate
Sound-absorbing material layer.
As an improvement outer profile boundary of the outer profile boundary of the sound-absorbing material layer relative to the sounding monomer
It is inwardly indented.
As an improvement the sound-absorbing material layer is rectangle or circle.
As an improvement the sound-absorbing material layer is acoustical cotton.
As an improvement the back cavity further includes the first chamber and second chamber positioned at sounding monomer both sides.
As an improvement also filling up sound-absorbing material in the first chamber and the second chamber.
The utility model has the beneficial effects that：The microphone device of the utility model is arranged in back cavity is located in sounding monomer
Inhibition sounding monomer between shell causes the sound-absorbing material layer that shell resonates, sound-absorbing material layer inhibiting sounding list when working
While causing shell to resonate when body running, and rear cavity space filling sound-absorbing material can be made full use of to improve low frequency performance.
【Description of the drawings】
Fig. 1 is the stereochemical structure decomposing schematic representation of the microphone device of the utility model；
Fig. 2 is the front view of the microphone device of the utility model；
Fig. 3 is the sectional view of the line A-A cutting in Fig. 2.
【Specific implementation mode】
The utility model is described in further detail below by specific implementation mode combination attached drawing 1 to Fig. 3, so as to energy
The advantages of enough more fully understanding the embodiment of the utility model and its various aspects.Below in an example, it provides in detail below
The purpose of embodiment is easy for becoming apparent from thorough explanation to the content of the utility model, rather than to the limit of the utility model
System.
Referring to figs. 1 to Fig. 3, the utility model provides a kind of microphone device, which includes shell 10 and be contained in
Sounding monomer 3 in shell 10, wherein shell 10 includes upper cover 1, the lower cover 2 opposite with upper cover 1, and upper cover 1 is common with lower cover 2
It assembles to form receiving space 4.
Receiving space 4 is separated into ante-chamber 41 and back cavity 42 by sounding monomer 3, specifically, sounding monomer 3 and upper cover 1 surround
Ante-chamber 41 is used for sounding；Sounding monomer 3, lower cover 2 and upper cover 1 surround back cavity 42 jointly, for improving frequency acoustic performance.
The suppression being located between sounding monomer 3 and shell 10 (being specially lower cover 2 in present embodiment) is equipped in back cavity 42
Sounding monomer 3 processed causes the sound-absorbing material layer 5 that shell 10 resonates, the sound-absorbing material layer 5 to have sound-absorbing and buffer dual when working
Effect while caused shell 10 resonates when sounding monomer 3 can be inhibited to work, and can make full use of the space of back cavity 42 to fill out
Filling sound-absorbing material improves low frequency performance.The material of sound-absorbing material layer 5 is preferably acoustical cotton, and but not limited to this, can also be it
Its sound-absorbing material that can play cushioning effect.
The outer profile boundary of sound-absorbing material layer 5 is inwardly indented relative to the outer profile boundary of sounding monomer 3, in other words, is inhaled
The outer profile boundary of sound material layer 5 than sounding monomer 3 outer profile boundary close to inside, sound-absorbing material layer 5 is preferably shaped to
Rectangle or circle.
Back cavity 4 further includes the first chamber 421 and second chamber 422 positioned at 3 both sides of sounding monomer, 421 He of first chamber
Second chamber 422 fills sound-absorbing material further to improve frequency acoustic performance.
Compared with prior art, the microphone device of the utility model be arranged in back cavity be located in sounding monomer and shell it
Between inhibition sounding monomer work when cause shell resonate sound-absorbing material layer, sound-absorbing material layer inhibit sounding monomer work when
While causing shell to resonate, and rear cavity space filling sound-absorbing material can be made full use of to improve low frequency performance.
Above-described is only the embodiment of the utility model, it should be noted here that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, improvement can also be made, but these belong to this practicality
Novel protection domain.
