The utility model provides a kind of loudspeaker module, and the loudspeaker module is provided with for accommodating sound-absorbing in back cavity
The storage tank of material, can improve the space availability ratio of back cavity.The storage tank forms air by ventilative packaging part and back cavity
Connection.This loudspeaker module fill process when sound-absorbing material is filled is simple, reduces sound-absorbing material and is directly entered back cavity shadow
Ring the situation of loudspeaker normal work.Fig. 1 shows the structure of loudspeaker module, it is seen then that the ventilative packaging part 3 is encapsulated in and encloses
Into the top of side wall 12 of storage tank 11, sound-absorbing material 4 is packaged with the storage tank 11 in ventilative packaging part 3 and side wall 12.Module
The other parts of the module casings 1 such as lid can also be fastened on module on housing 1, not shown in figure, the utility model is not to this
Limited.The material of the module casing can use PC (makrolon), it is further possible to using PC and glass fibers
The composite of dimension, or PC and ABS (ABS resin) composite as module casing material.Above-mentioned material can be protected
Card module casing has good structural stability.
The loudspeaker module mainly includes module casing, loudspeaker assembly, ventilative packaging part and sound-absorbing material.Fig. 2
The part-structure of the module casing 1 is shown, there is the space for accommodating loudspeaker assembly 2 in module casing 1, it is described to raise
Sound device assembly 2 can be fixedly installed in module casing 1, and Fig. 1 shows loudspeaker assembly 2 and is arranged in module casing 1
Structure type.The inner chamber of module casing 1 can be divided into ante-chamber and back cavity by the loudspeaker assembly 2, and ante-chamber directly connects with the external world
Logical, for directly speaking, back cavity is used to eliminate anti-phase sound wave, treatment bass etc..In the inner side of the module casing 1, with from rear
The side wall 12 extended on the inwall in chamber, the side wall 12 is surrounded and forms storage tank 11, as shown in Figure 2.
The sound-absorbing material 4 is filled in the storage tank 11, for sponging the sound wave in incoming back cavity, such as Fig. 3 institutes
Show.In order to prevent sound-absorbing material 4 from being leaked into back cavity from storage tank 11, the ventilative packaging part 3 is fixed and is encapsulated in the side wall
12 top, as shown in figure 1, the ventilative packaging part 3 can stop that sound-absorbing material 4 spills, but allows air therefrom saturating simultaneously
Cross, to connect sound-absorbing material and back cavity.Alternatively, the ventilative packaging part can be by materials such as non-woven fabrics, wire netting or silk screens
Material is made, and this material can either in structure form packaging effect, and air can be allowed to pass therethrough again, so as to reach encapsulation
With ventilative technique effect.Specific material of the utility model not to packaging part of breathing freely is limited, those skilled in the art
Can be selected according to actual performance requirement.Fig. 1 shows the structure that ventilative packaging part 3 is encapsulated on module casing 1.
Preferably, in order to improve the stability that ventilative packaging part is fixed on module casing, the ventilative packaging part can be with
The top of the side wall is fixed on by hot melting process.Hot melt technique for fixing can be carried out after sound-absorbing material is filled, is heated
Technique melts the top of the side wall, and the ventilative packaging part immerses the top of side wall, top side wall solidification to be melted, institute
Ventilative packaging part is stated reliably to be encapsulated on the side wall.In addition to being fixed by hot melting process, it would however also be possible to employ viscous
The form such as connect to be fixed, the utility model is limited not to this.
Especially, fix, prevent from coming off, generally, the ventilative packaging part and side in order to ensure the reliability of ventilative packaging part
The width of the contact area at the top of wall should be maintained in the range of 0.4-1.5mm.If the width for contacting between the two is narrow,
Combination power is smaller, and ventilative packaging part is possible to come off, if the width of contact is wide, although ensure that combination power
It is larger, but side wall can occupy space bigger in module casing, reduce space availability ratio.As shown in Fig. 2 side wall 12 has
Certain thickness, the thickness is presented as width at the top of side wall 12, the width at the top of side wall 12 be substantially equal to ventilative packaging part 3 with
Side wall 12 contacts the width of fixation.Those skilled in the art can improve consolidating for ventilative packaging part by adjusting the thickness of side wall
Determine reliability.
Preferably, as shown in Figure 2,4, can be provided with the region of module casing 1 for constituting the storage tank 11 and filled out
Fill hole 13.The filling hole 13 is communicated in the storage tank 11, and the sound-absorbing material 4 can be filled into from the filling hole 13
In storage tank 11.This structure design allows for the suitable of the installation step of loudspeaker module and the filling step of sound-absorbing material
Sequence.In this embodiment, ventilative packaging part 3 first can be encapsulated in the top of side wall 12.Afterwards alternatively, to loudspeaker
The part such as lid is assembled successively on component, module.Complete after all assembling is fixed, then by the filling hole 13 by sound absorber
Material 4 is fitted into storage tank 11.Or, sound-absorbing material 4 can be filled into storage tank 11 from filling hole 13 first, carry out again afterwards
The assembling of the part such as lid on loudspeaker assembly, module.The above-mentioned installation step of respective outer side edges of module casing 1 shown in Fig. 4, can subtract
Small sound-absorbing material 4 drains to the possibility of the region of loudspeaker assembly 2.
Further, seal is also provided with the filling hole 13, the seal is used to seal filling hole 13,
Sound-absorbing material 4 is avoided to be spilt from filling hole 13.Alternatively, in the outside of the module casing 1, it is provided with the filling hole 13
Sealed groove 14, as shown in Figure 4.The seal can be embedded in the sealed groove 14, can preferably to filling hole reality
Existing sealing effectiveness.It is this preferred embodiment in, on what seal can be more stable be fixed on filling hole 13.The sealing
Groove and seal can also be arranged on the inner side in the filling hole, and the utility model is limited not to this.
Preferably, for the sound-absorbing effect of back cavity, the sound-absorbing material can be zeolite structured particle or activated carbon
Grain.In a particular embodiment, those skilled in the art can adopt according to the difference required loudspeaker module performance, selection
With zeolite structured particle and activated carbon granule with diverse microcosmic pore passage structure, the utility model is limited not to this.Enter
One step ground, in order to make full use of the space of loudspeaker module back cavity, improves the sound-absorbing effect of sound-absorbing material, above-mentioned sound-absorbing material
Particle size range is preferably between 0.1-0.5mm.If sound-absorbing material particle diameter is excessive, the space availability ratio of back cavity declines,
If the particle diameter of sound-absorbing material is too small, the too small reduction sound-absorbing effect of inter-granular porosity, and influence the selection of ventilative packaging part.Institute
So that the grain diameter of the sound-absorbing material is preferably within the above range.
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
