Abstract
The invention discloses a sounding device which comprises a shell with an accommodating space and a sounding monomer placed in the shell. The sounding device is provided with a foam retaining wall for dividing the shell into a front cavity and a rear cavity opposite to the front cavity; the front cavity is communicated with the outside; the sounding monomer is placed in the front cavity; and a sound adsorption material is filled in the rear cavity. Compared with the relevant art, the sounding device has the advantage that the low-frequency sound effect is better.
Description
[technical field]
The present invention relates to a kind of microphone device, particularly relate to a kind of microphone device be used on portable type electronic product.
[background technology]
In the process of the portable equipment fast developments such as mobile phone, people are more and more stronger to the Functional Requirement of product, for this function of Music Appreciation of mobile phone, in order to make entertainment effect stronger, there is the pattern that music belt vibrates, thus, the development also corresponding quickening of microphone device.
The microphone device of correlation technique, it comprises the housing with receiving space and the sounding monomer be placed in described receiving space, and described receiving space is separated into ante-chamber and the back cavity relative with described ante-chamber by described sounding monomer, and described ante-chamber communicates with the external world.This structure makes microphone device have larger back cavity, thus makes the microphone device of correlation technique have good low frequency audio.
But, its back cavity of the microphone device of correlation technique is enclosed construction, gas in back cavity produces inhibition to the athletic meeting of described vibrating diaphragm, the high-frequency resonant frequency of correlation technique microphone device even can be made to increase, low frequency audio reduces, thus makes the acoustical behavior of the microphone device of correlation technique produce negative effect.
Therefore, be necessary to provide a kind of new technical scheme to overcome above-mentioned defect in fact.
[summary of the invention]
The object of this invention is to provide the microphone device that a kind of low frequency audio is good.
The object of the present invention is achieved like this:
A kind of microphone device, it comprises the housing with receiving space and the sounding monomer be placed in described housing, described microphone device is provided with foam barricade and described housing is separated into ante-chamber and the back cavity relative with described ante-chamber, described ante-chamber communicates with the external world, described sounding monomer is placed in described ante-chamber, is filled with sound-absorbing material in described back cavity.
Preferably, described microphone device is also provided with the packaging bag of accommodating coated described sound-absorbing material, and described packaging bag is made up of foam, described in sound-absorbing material is housed packaging bag be filled in back cavity.
The present invention has the following advantages: compared with correlation technique, and its bass validity of microphone device of the present invention can be better.
[accompanying drawing explanation]
Fig. 1 is the structural representation for microphone device of the present invention.
[embodiment]
Below in conjunction with accompanying drawing, the present invention is elaborated.
As shown in Figure 1, a kind of microphone device 10, it comprises the housing 1 with receiving space and the sounding monomer 2 be placed in housing 1, described microphone device 10 is provided with foam barricade 5 and housing 1 is separated into ante-chamber 4 and the back cavity 3 relative with ante-chamber 4, ante-chamber 4 communicates with the external world, and described sounding monomer 2 is placed in described ante-chamber 4.Sound-absorbing material 6 is filled with in described back cavity 3.More excellent, described microphone device 10 is also provided with the packaging bag (not shown) of accommodating coated described sound-absorbing material 6, and described packaging bag is made up of foam, described in sound-absorbing material 6 is housed packaging bag be filled in back cavity 3.
Utilize foam barricade housing to be separated into ante-chamber and the back cavity relative with ante-chamber, be filled in by sound-absorbing material in the middle of back cavity, foam barricade can prevent filled sound-absorbing material from penetrating in sounding monomer.Preferably, described sound-absorbing material is contained in the packaging bag of being made up of foam, the described packaging bag that sound-absorbing material is housed is filled in back cavity, and the packaging bag that foam is made is packed into back cavity certain damping effect, avoids the sound-absorbing material of filling to produce noise owing to rocking.Meanwhile, the packaging bag that foam is made can adapt to complicated rear cavity shape.Because foam is enough sparse, very little to the performance impact of microphone device.Compared with correlation technique, its bass validity of microphone device of the present invention can be better.
Above-described is only embodiments of the present invention, it should be pointed out that for the person of ordinary skill of the art at this, without departing from the concept of the premise of the invention, can also make improvement, but these all belongs to protection scope of the present invention.
Claims (1)
1. a microphone device, it comprises the housing with receiving space and the sounding monomer be placed in described housing, described microphone device is provided with foam barricade and described housing is separated into ante-chamber and the back cavity relative with described ante-chamber, described ante-chamber communicates with the external world, described sounding monomer is placed in described ante-chamber, it is characterized in that: in described back cavity, be filled with sound-absorbing material, described microphone device is also provided with the packaging bag of accommodating coated described sound-absorbing material, described packaging bag is made up of foam, described in sound-absorbing material is housed packaging bag be filled in back cavity.
