This utility model provides a kind of speaker module, is provided with and is combined by support shell and acoustical cotton in this speaker module
The attraction assembly being formed, can avoid being formed the acoustic constructions such as pipeline, slit between sound-absorbing assembly and module casing as far as possible.Described
Speaker module includes module casing, loudspeaker assembly and sound-absorbing assembly.In described module casing, there is accommodating chamber, described raise
Sound device assembly is arranged in described accommodating chamber, and described sound-absorbing assembly is also disposed in described accommodating chamber, and it is configured to described appearance
Receive chamber formed filling effect.Especially, described sound-absorbing assembly is included for accommodating the support shell attracting granule and being arranged on described support
Acoustical cotton on shell outer surface.When described sound-absorbing assembly is filled in accommodating chamber, described support shell may be with the inwall of accommodating chamber
Between there is gap, these gaps can be blocked by the acoustical cotton being arranged on described support shell outer surface, and provides sound-absorbing
Condition.Can be fitted with the contact internal walls of accommodating chamber in the surface of described acoustical cotton and support shell, seal gap that may be present.
Specifically, Fig. 1 shows a kind of structure of the sound-absorbing assembly 2 in embodiment, and described acoustical cotton 22 can be arranged
On two long and narrow side walls of described support shell 21, thus prevent from holding in the palm produce between the side wall of shell 21 and the inwall of accommodating chamber narrow
Seam.Further, as shown in Fig. 2 when this sound-absorbing assembly 2 is arranged in the accommodating chamber 11 of module casing 1, holding in the palm the bottom of shell 21
Portion can be contacted with the bottom of accommodating chamber 11, and the acoustical cotton 22 then contact internal walls with accommodating chamber 11.So, in sound-absorbing assembly 2
Surrounding will not form slit or pipeline, it is to avoid the acoustical behavior of module is impacted.This utility model is not intended to limit sound-absorbing
The position of cotton 22 setting around support shell 21, in other embodiments, described acoustical cotton can also be arranged on described support shell
Bottom, thus prevent from holding in the palm produce slit between the bottom of shell and the bottom surface of accommodating chamber.
Alternatively, as shown in Figure 1, 2, the top of described support shell 21 can have opening, and sound-absorbing material granule can be from institute
State the inside being filled into described support shell 21 at opening.Especially, described opening has flange 211, and this flange 211 can be to support
The structure that shell 21 outside extends, or can also be the structure extending a small distance to support shell 21 outside and inner side.Described convex
Encapsulation screen cloth 212 can be provided with edge 211, described encapsulation screen cloth 212 can be fitted on described flange 211, to close support
The inner space of shell 21.Described encapsulation screen cloth 212 should be made up of gas permeable material, so that sound smoothly incoming can hold in the palm shell 21
In, make sound-absorbing material granule play sound-absorbing effect.
Especially, as shown in Figure 1, 2, described acoustical cotton 22 is preferably provided at the lower section of described flange 211.Due to described convex
Edge 211 extends to support shell 21 outside, so causing the support shell 21 side wall of flange 211 downside cannot closely be attached to accommodating chamber 11
In vertical inner wall.Described acoustical cotton 22 can be filled in the region of flange 211 lower section, for being fitted in the inside of accommodating chamber 11
On, prevent from forming slit.Generally, acoustical cotton 22 can be with the side of the lower surface of flange 211 and the support shell 21 of flange 211 lower section
Wall bonding is it is ensured that reliable annexation.
Alternatively, this utility model is not intended to limit the quantity of the support shell that described sound-absorbing assembly includes, so, described sound-absorbing
Assembly can include multiple support shells, such as 2 or more.Wherein, easily produce between the support shell of mutually neighbour setting slit or
Pipeline, described acoustical cotton can be arranged on the gap location between each support shell, blocks slit.
Preferably, in order to provide more preferable sound-absorbing effect, in described support shell, the sound-absorbing granule of filling can be that non-foamed is inhaled
Sound material granule.In non-foamed sound-absorbing material granule, there is multi-stage artery structure, can effectively provide sound-absorbing effect, simultaneously to gas
The change of pressure has good response sensitivity, and it will not hinder the vibration of loudspeaker assembly.
In addition, the accommodating chamber of described module casing is used for accommodating loudspeaker assembly and sound-absorbing assembly, wherein, when speaker group
When part is put in accommodating chamber, loudspeaker assembly combines, with the inwall of module casing, the rear portion limiting in accommodating chamber.After this
Cavity region is connected with loudspeaker assembly, is mainly used in balancing acoustic pressure, and can play the effect adjusting low-frequency sound performance.
Alternatively, described sound-absorbing assembly is filled in described rear portion.Fig. 3 shows that described sound-absorbing assembly 2 is arranged on module casing 1
In stereoeffect, wherein, the subregion of module casing 1 is used for accommodating loudspeaker assembly, and the region that sound-absorbing assembly 2 is located
For rear portion.
Especially, the sound-absorbing material granule in support shell can also be applied in combination by those skilled in the art with acoustical cotton, with
Reach the performance requirement to speaker F0.Wherein, the sound-absorbing material granule in support shell is mainly used in reducing F0；Acoustical cotton is mainly used
In adjusting sensitivity curve, eliminating standing wave, it is also possible to play the effect of a certain degree of reduction F0, but limited use.?
The use ratio of sound-absorbing material granule and acoustical cotton in actual application, according to the requirement of speaker F0, can be selected.Example
As in one embodiment, the volume of sound-absorbing material granule can be 0.6 cubic centimetre, and it can make the F0 of speaker protect
Hold in 600Hz.And under the conditions of same loadspeaker structure, in another embodiment, using 0.4 cubic centimetre of sound-absorbing
Material granule coordinates 1.0 cubic centimetres of acoustical cotton, and the F0 of speaker equally can be made to be maintained at 600Hz.It can be seen that, by sound absorber
Material can be used cooperatively with acoustical cotton, in the case of can reaching identical acoustic performance requirements, it is possible to reduce sound-absorbing material
The usage amount of grain.Meanwhile, acoustical cotton is filled in and accommodates around the support shell of sound-absorbing material granule, can play elimination standing wave, tune
The effects such as section sensitivity.This utility model does not do concrete restriction to the use of two kinds of sound-absorbing materials, and those skilled in the art can
To be adjusted according to practical situation and to design.
Although being described in detail to some specific embodiments of the present utility model by example, this area
It is to be understood by the skilled artisans that above example is merely to illustrate, rather than in order to limit scope of the present utility model.This
Field it is to be understood by the skilled artisans that can be in the case of without departing from scope and spirit of the present utility model, to above example
Modify.Scope of the present utility model is defined by the following claims.
