Description
Technical field
The utility model is related to electro-acoustic product technical field, more particularly to a kind of sound-absorbing component and provided with the sound-absorbing component
Loudspeaker module.
Background technology
Loudspeaker module is the important acoustic element of portable electric appts, for completing between electric signal and voice signal
Conversion, be a kind of energy conversion device.Existing loudspeaker module generally includes to contain loudspeaker list in shell, shell
Whole module inner chamber is separated into two cavitys of the preceding operatic tunes and the rear operatic tunes by body, loudspeaker monomer.In order to reduce the F0 (resonance of module
Frequency), improve low frequency frequency response, spread bandwidth, it will usually sound-absorbing material is used in the rear operatic tunes, sound-absorbing material can effectively drop
The F0 of low module, and make it that intermediate frequency frequency response curve is more smooth, it is an important component in loudspeaker module.Sound-absorbing material
The degree worked in the rear operatic tunes and loading, the filling mode of sound-absorbing material in the rear operatic tunes have direct relation, rear
Lifting of the filling sound-absorbing material as much as possible to loudspeaker module performance has positive meaning in the operatic tunes.
The sound-absorbing material generally used in loudspeaker module is acoustical cotton, with technical staff to performance requirement increasingly
Height, the sound-absorbing effect of acoustical cotton can not meet the performance requirement of loudspeaker module.Therefore, zeolite powder is made technical staff
The particles filled rear operatic tunes to loudspeaker module of sound-absorbing, its sound-absorbing effect is better than acoustical cotton, and current sound-absorbing particle is in loudspeaker mould
The main application mode of group has three kinds：
First, sound-absorbing particle is rolled into wrapper with screen cloth support shell, is directly placed into the rear operatic tunes, due to screen cloth profile not
With plasticity, flat can only be made, space availability ratio is relatively low, cause sound-absorbing particles filled most smaller.
2nd, sound-absorbing particle is loaded into hard support shell, support shell one side is sealed with screen cloth for breathing freely, because hard support shell does not have
There is ventilating performance, airflow is only carried out by screen cloth one side, causes sound-absorbing particle sound-absorbing effect to weaken；Simultaneously shell is held in the palm in design
When, in order to avoid screen cloth face is shut by the shell of loudspeaker module, it is necessary to which certain interval will be left between screen cloth and shell, so that
The particles filled amount of sound-absorbing is caused to reduce.
3rd, filling class design, certain area is surrounded in the rear operatic tunes using injection molding material, and sound-absorbing is particles filled to this area
Domain, is separated between the region and loudspeaker monomer using screen cloth, and such design only has screen cloth one side to have gas permeability, in design
Screen cloth is also required to leave a certain distance with loudspeaker monomer, and the particles filled amount of sound-absorbing is smaller, and surrounds the injection molding material in the region
Operatic tunes volume after occupancy, negative interaction is played to reduction F0.
Three of the above mode has that the particles filled amount of sound-absorbing is small, and rear operatic tunes utilization rate is low, the problem of sound-absorbing effect is poor,
Acoustic performance requirements expected from product can not be reached.
Utility model content
For drawbacks described above, first technical problem to be solved in the utility model is to provide a kind of sound-absorbing component, this
Sound-absorbing component can make full use of the space of the rear operatic tunes, and the particles filled amount of sound-absorbing is big, and sound absorption qualities are good, while sound-absorbing particle is not fragile
It is broken.
Based on same inventive concept, second technical problem to be solved in the utility model is to provide a kind of loudspeaker
Module, the sound-absorbing component of this loudspeaker module can sufficiently utilize the space of the rear operatic tunes, and more preferably, frequency band is wider for middle low frequency performance,
Overall acoustical behavior is good.
To solve above-mentioned first technical problem, the technical solution of the utility model is：
A kind of sound-absorbing component, including shell and the sound-absorbing particle being encapsulated in the support shell are held in the palm, the support shell includes ring-type
Shell main body is held in the palm, the two ends of the support shell main body are respectively provided with a sealed piece for being used to seal the sound-absorbing particle, the support shell main body
Material be acoustical cotton, at least one described sealed piece in sealed piece described in two is plastic tab.
As a kind of embodiment, a sealed piece in sealed piece described in two is the plastic tab, another
The sealed piece is acoustical cotton thin slice.
As another embodiment, two sealed pieces in sealed piece described in two are the plastic tab.
Wherein, it is bonded as one between sealed piece described in the support shell main body and two by glue or double faced adhesive tape.
Wherein, the shape and size of sealed piece described in two are consistent with the outward flange of the support shell main body.
To solve above-mentioned second technical problem, the technical solution of the utility model is：
Loudspeaker monomer is contained in a kind of loudspeaker module, including shell, the shell, the loudspeaker monomer will be whole
Individual module inner chamber, which is divided into two cavitys of the preceding operatic tunes and the rear operatic tunes, the rear operatic tunes, is provided with sound-absorbing component, the sound-absorbing component
For above-mentioned sound-absorbing component.
Employ after above-mentioned technical proposal, the beneficial effects of the utility model are：
Due to the sound-absorbing particle that the utility model sound-absorbing component includes support shell and is encapsulated in support shell, support shell includes acoustical cotton
The ring-type support shell main body being made, at least one that the two ends of support shell main body are respectively provided with a sealed piece, two sealed pieces is plastic tab.
Using support shell main body of the acoustical cotton as sound-absorbing component so that the utility model has advantages below compared with prior art：
First, acoustical cotton has sound absorption in itself, can equally reduce the F0 of module, shared rear operatic tunes volume must have
The utilization of effect so that sound-absorbing component has reached optimal sound-absorbing effect.
2nd, acoustical cotton has good gas permeability, in design support shell, between the shell of acoustical cotton and loudspeaker module not
With gap is left, air-flow can enter the particles filled area of sound-absorbing by acoustical cotton, so that the loading of sound-absorbing particle is most
Bigization, reduction module F0 effect is more preferable.
3rd, at least one sealed piece is the plastic tab of hard, effectively can prevent acoustical cotton from deforming, it is to avoid internal
Sound-absorbing particle crushed because being squeezed, it is ensured that the sound-absorbing effect of sound-absorbing particle, be more beneficial for reducing loudspeaker module
F0。
Because two sealed pieces are plastic tab, more preferable styling can be played to acoustical cotton, while plastic tab
It is cheap, advantageously reduce the cost of product.
Due to being filled with above-mentioned sound-absorbing component in the rear operatic tunes of the utility model loudspeaker module, so that the sky of the operatic tunes thereafter
Between be fully utilized, more preferably, frequency band is wider, and overall acoustical behavior is more preferable for the middle low frequency performance of module.
In summary, the utility model sound-absorbing component and the loudspeaker module provided with the sound-absorbing component solve prior art
In after the few technical problem of the particles filled amount of sound-absorbing, the utility model sound-absorbing component and raising one's voice provided with the sound-absorbing component in the operatic tunes
Device module sufficiently make use of the rear operatic tunes space of module, and the particles filled amount of sound-absorbing is more, and middle low frequency performance is more preferable, acoustical behavior
It is good.
