The utility model provides a sounding device air penetrability is high, resonance frequency is low and the low frequency performance is good, and whole sounding device's reliability is high.
Description
[technical field]
The utility model relates to a kind of microphone device, particularly relates to a kind of microphone device be used on Portable movable electronic product.
[background technology]
In recent years, Portable movable electronic product is more and more liked by people, and the expectation of people to multi-functional product is also more and more higher, for Music Appreciation aspect, the music pattern of band vibration becomes the first-selected requirement of a lot of people, the corresponding matching technique of microphone device also development for this reason.
The microphone device of correlation technique, comprise the housing of tool receiving space and be contained in the sounding monomer of described receiving space, described receiving space is separated into the ante-chamber and back cavity that are oppositely arranged by described sounding monomer.
Under normal circumstances, the common sound-absorbing material of filling in described back cavity makes that the air penetrability of whole microphone device is low, resonance frequency is high and low frequency performance is poor, and the reliability of whole microphone device is low.
[utility model content]
In order to solve low, the resonance frequency high and low frequency poor performance of air penetrability that above-mentioned microphone device exists and the low technical problem of reliability, the utility model provides that a kind of air penetrability is high, resonance frequency is low, low frequency performance is good and the microphone device that reliability is high.
The utility model provides a kind of microphone device, comprise the housing with receiving space and the sounding monomer being contained in described receiving space, described receiving space is separated into ante-chamber and the back cavity relative with described ante-chamber by described sounding monomer, described ante-chamber communicates with the external world, described microphone device also comprises the sound-absorbing material be filled in described back cavity, and described sound-absorbing material is staggered in threadiness is loose.
In a kind of preferred embodiment of the microphone device provided at the utility model, described sound-absorbing material is at least one in wool and polypropene staple.
In a kind of preferred embodiment of the microphone device provided at the utility model, described sounding monomer comprises the front operatic tunes and the rear operatic tunes, and the described front operatic tunes is communicated with described ante-chamber, and the described rear operatic tunes is communicated with described back cavity.
In a kind of preferred embodiment of the microphone device provided at the utility model, the resonance frequency range of described microphone device is 700-800Hz.
Compared to prior art, the microphone device that the utility model provides has following beneficial effect:
One, by filling in the back cavity of microphone device in the loose staggered sound-absorbing material of threadiness, make the air penetrability of microphone device high.
Two, comprising the sound-absorbing material of wool and polypropene staple by using, making the resonance frequency of microphone device low and low frequency performance good.
Three, by filling full sound-absorbing material in the back cavity of microphone device, sound-absorbing material can not rock because of moving of microphone device, improves the reliability of microphone device.
[accompanying drawing explanation]
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the microphone device that the utility model provides;
Fig. 2 is the microphone device that provides of the utility model and the air penetrability comparison diagram of microphone device of filling common sound-absorbing material.
[embodiment]
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, is the structural representation of the microphone device that the utility model provides.Described microphone device 1 comprises the housing 11 with receiving space (not shown) and the sounding monomer 13 being contained in described receiving space, described receiving space is separated into ante-chamber 111 and the back cavity 113 relative with described ante-chamber 111 by described sounding monomer 13, and described ante-chamber 111 communicates with the external world.The monomer of sounding described in the present embodiment 13 is loud speaker, it comprises the vibrating diaphragm 131 of the sounding because of vibration in atmosphere, described sounding monomer 13 also comprises front operatic tunes (not shown) and rear operatic tunes (not shown), the described front operatic tunes is communicated with described ante-chamber 111, and the described rear operatic tunes is communicated with described back cavity 113.
In the present embodiment, described back cavity 113 is filled with sound-absorbing material 1131, full described back cavity 113 filled by described sound-absorbing material 1131, described sound-absorbing material 1131 also can be partially filled described back cavity 113, more excellent, full described back cavity 113 filled by described sound-absorbing material 1131, after filling full described sound-absorbing material 1131 in described back cavity 113, described sound-absorbing material 1131 just can not rock because of described moving of microphone device 1, improves the reliability of described microphone device 1.Described sound-absorbing material 1131 is staggered in threadiness is loose.
Refer to Fig. 2, be the microphone device that provides of the utility model and the air penetrability comparison diagram of microphone device of filling common sound-absorbing material, make in the loose staggered described sound-absorbing material 1131 of threadiness the air penetrability of described microphone device 1 apparently higher than the air penetrability of microphone device of filling common sound-absorbing material.
Described sound-absorbing material 1131 is at least one in wool and polypropene staple, and described wool and described polypropene staple are all staggered in threadiness is loose.
The resonance frequency range of described microphone device 1 is 700 ~ 800Hz, and compared to the resonance frequency of the microphone device of the common sound-absorbing material of filling, this frequency range reduces 50 ~ 100Hz.
The described microphone device 1 that the utility model provides has following beneficial effect:
One, by filling in the described back cavity 113 of described microphone device 1 in the loose staggered described sound-absorbing material 1131 of threadiness, make the air penetrability of described microphone device 1 high.
Two, comprising the described sound-absorbing material 1131 of wool and polypropene staple by using, such that the resonance frequency of described microphone device 1 is low and low frequency performance good.
Three, by filling full described sound-absorbing material 1131 in chamber 113 in the rear, described sound-absorbing material 1131 just can not rock because of described moving of microphone device 1, improves the reliability of described microphone device 1.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
