Description
Technical field
This utility model relates to a kind of encapsulation sound-absorbing assembly containing air channel structure for speaker, specifically
Relate to the air channel structure of sound-absorbing component bottom.
Background technology
In recent years, under the most lightening main trend of electronic product, important zero as electronic product
The loudspeaker unit of part also to be gone with the tide of historical development, and constantly develops to flattening.But miniature SPK module is inclined
Graduation, necessarily causes acoustics back cavity cavity volume to reduce, causes harmonic frequency of loudspeakers F0 to raise, low frequency
Sensitivity decrease, adversely affects speaker acoustical behavior.For solve speaker module lightening with
Contradiction between acoustical behavior, technical staff find by porous material (as activated carbon, natural zeolite powder,
Active silica, molecular sieve or the mixture etc. made according to particular types and ratio) it is filled into rear sound
Intracavity, utilizes the internal specific physical duct of porous material to construct rear operatic tunes gas quick adsorption-desorption property
Matter, it is achieved speaker acoustics back cavity resonance space virtual increase effect, thus it is humorous to be effectively reduced speaker
Vibration frequency F0, improves low frequency sensitivity, meet client to speaker module flattening and high characteristics of acoustic can
Double requirements.
Such as in Chinese utility model patent " speaker module " (application number: 201510173142.2) public affairs
Open a kind of speaker, the rear operatic tunes has been provided with sound-absorbing assembly.Chinese utility model patent " speak by side
The speaker module of structure " (application number: 201420214862.X) discloses the operatic tunes before and after a kind of setting
Speaker module.Chinese utility model patent " sound-absorbing material preparation method and sound-absorbing material " (application
Number: 201510560252.4) in disclose a kind of sound-absorbing material, for improving the acoustical behavior of speaker.
After porous material is filled into module at present, the scheme of the operatic tunes usually holds in the palm shell-type encapsulation scheme, first
First porous material is encapsulated in torr shell and makes sound-absorbing part, then sound-absorbing part is fixed to speaker module
In, thus reach to improve the purpose of speaker module acoustical behavior.This kind of scheme has following defects that torr
Shell, originally as plastic material, does not have aeration, and only screen cloth one side is ventilative, during diaphragm of loudspeaker vibration
Produce air-flow, owing to ventilating return cannot be formed, air-flow is had the strongest weakening effect, thus results in envelope
It is contained in interior porous material gas quick adsorption-desorption is restricted so that improve speaker mould
Group acoustical behavior effect is deteriorated.
Problem present on greatly limit porous sound-absorbing material for improving Microspeaker module
Acoustical behavior effect, reduces the effective rate of utilization of porous sound-absorbing material, and the covert product manufacturing that increases becomes
This, cause the wasting of resources.
Utility model content
For the problems referred to above of the prior art, the purpose of this utility model is to provide a kind of encapsulation sound-absorbing

Further, described torr shell material matter is the plastics such as polyethylene, polypropylene, Merlon or polyurethane,
Thickness is 0.05～0.5 millimeter.
Further, described ventilation partition apparatus be the materials such as non-woven fabrics, wire netting or screen cloth one or
Multiple compound, Air permenbility scope is: 50-5000cc/cm2S, thickness is 0.01-0.1 millimeter.
Further, described screen cloth material be the materials such as polyethylene, polypropylene, acrylon or nylon one or
Multiple compound.
Being provided with the speaker of above-mentioned encapsulation sound-absorbing assembly, described speaker is provided with the front operatic tunes and the rear operatic tunes,
The rear operatic tunes is provided with described encapsulation sound-absorbing assembly.
The encapsulation sound-absorbing assembly using said structure to arrange has the advantage that
This product, by arranging air channel at encapsulation sound-absorbing component bottom, defines ventilating return, speaker
Produce air-flow during diaphragm oscillations, can the most successfully be applied in sound-absorbing assembly on porous material, porous
Property material for gaseous carries out quick adsorption-desorption, it is achieved the speaker acoustics virtual increasing of back cavity resonance space
Big effect, improves speaker module acoustical behavior.
Compared with traditional torr shell-type sound-absorbing part, this product can improve porous sound-absorbing material and effectively utilize
Rate so that it is preferably improve speaker module acoustical behavior.
The effect of the ventilation partition apparatus set by this product is to stop the material of encapsulation in sound-absorbing part
Enter in loudspeaker monomer, it is to avoid other assemblies of speaker are adversely affected, is to ensure that simultaneously
Good aeration, sound-absorbing granule competence exertion its improve the effect of speaker module acoustical behavior.
The sound-absorbing granule that this product is filled is that porous material is (such as molecular sieve, activated carbon, activity dioxy
SiClx, natural zeolite powder or the mixture etc. made according to particular types and ratio) by forming technique system
Become, be the sound-absorbing assembly effective ingredient that improves speaker acoustical behavior.
