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, relate in particular to a kind of microphone device that is used on the portable type electronic product.
[background technology]
In the fast-developing process of portable equipments 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; The pattern that the music belt vibration occurred, thus, the also corresponding quickening of the development of microphone device.
The microphone device of correlation technique, it comprises housing with receiving space and the sounding monomer that places in the said receiving space, and said sounding monomer is separated into ante-chamber and the back cavity relative with said ante-chamber with said receiving space, and said ante-chamber communicates with the external world.This structure makes microphone device that bigger back cavity arranged, thereby makes the microphone device of correlation technique have low frequency audio preferably.
Yet; Its back cavity of the microphone device of correlation technique is an enclosed construction; Gas in the back cavity produces inhibition to the athletic meeting of said vibrating diaphragm; Even can make the high-frequency resonant increase frequency of correlation technique microphone device, the low frequency audio reduces, thereby 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 defective in fact.
[summary of the invention]
The purpose of this invention is to provide the good microphone device of a kind of low frequency audio.
The objective of the invention is to realize like this:
A kind of microphone device; It comprises housing with receiving space and the sounding monomer that places in the said housing; Said microphone device is provided with the foam barricade said housing is separated into ante-chamber and the back cavity relative with said ante-chamber; Said ante-chamber communicates with the external world, and said sounding monomer places said ante-chamber, is filled with sound-absorbing material in the said back cavity.
Preferably, said microphone device also is provided with accommodates the packaging bag that coats said sound-absorbing material, and said packaging bag is processed by foam, and the said packaging bag that sound-absorbing material is housed is filled in back cavity.
The present invention has the following advantages: compare with correlation technique, its low frequency audio performance of microphone device of the present invention is better.
[description of drawings]
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 housing 1 with receiving space and the sounding monomer 2 that places in the housing 1; Said microphone device 10 is provided with foam barricade 5 housing 1 is separated into ante-chamber 4 and the back cavity 3 relative with ante-chamber 4, and ante-chamber 4 communicates with the external world, and said sounding monomer 2 places said ante-chamber 4.Be filled with sound-absorbing material 6 in the said back cavity 3.More excellent, said microphone device 10 also is provided with accommodates the packaging bag (not shown) that coats said sound-absorbing material 6, and said packaging bag is processed by foam, and the said packaging bag that sound-absorbing material 6 is housed is filled in the back cavity 3.
Utilize the foam barricade that housing is separated into ante-chamber and the back cavity relative with ante-chamber, sound-absorbing material is filled in the middle of the back cavity, the foam barricade can prevent that the sound-absorbing material of being filled from penetrating in the sounding monomer.Preferably; Said sound-absorbing material is contained in the packaging bag of being processed by foam; The said packaging bag that sound-absorbing material is housed is filled in the back cavity, and the packaging bag that foam is processed is packed into back cavity has certain damping effect, and the sound-absorbing material of avoiding filling produces noise owing to rocking.Simultaneously, the foam packaging bag of processing can adapt to complicated back cavity shape.Because foam is enough sparse, and is very little to the performance impact of microphone device.Compare with correlation technique, its low frequency audio performance of microphone device of the present invention is better.
Above-described only is execution mode of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
Claims (2)
1. microphone device; It comprises housing with receiving space and the sounding monomer that places in the said housing; Said microphone device is provided with the foam barricade said housing is separated into ante-chamber and the back cavity relative with said ante-chamber; Said ante-chamber communicates with the external world, and said sounding monomer places said ante-chamber, it is characterized in that: be filled with sound-absorbing material in the said back cavity.
2. microphone device according to claim 1 is characterized in that: said microphone device also is provided with accommodates the packaging bag that coats said sound-absorbing material, and said packaging bag is processed by foam, and the said packaging bag that sound-absorbing material is housed is filled in back cavity.
