The first embodiment of first retaining wall 122 and the second retaining wall 123 can also be applied to the structure of the shell 10；Specifically
, the side wall of the lower cover includes the first side wall 1251 and second sidewall 1252.In a still further embodiment, the sub- gear
Wall (the first sub- retaining wall 1222 of sub- retaining wall 1221 or the second or the sub- retaining wall 1231 of third or the 4th sub- retaining wall 1232) can also be under
The bottom wall of lid connects.
It certainly, can also be by the first retaining wall 122 and in the other embodiments of first retaining wall 122 and the second retaining wall 123
Two retaining walls 123 are set on upper lid or on the bottom wall of lower cover, and specific structure can refer to above embodiments, need not go to live in the household of one's in-laws on getting married one by one herein
It states.
Specifically, in order to further prevent sound-absorbing material from entering vibration cavity by the two sides avris of annular divider 30
521, the position that the inner wall of the shell 10 corresponds to separator 30 is equipped with elastomeric pad, and 30 elasticity of separator is only butted on elasticity
Gasket.Certainly, elastomeric pad may be alternatively provided as a part of separator 30, that is, separator 30 may also include elastomeric pad, elasticity
The side of separator 30 is arranged in gasket.
Certainly, in other embodiments of the invention, the modes such as limiting groove can also be shaped on the inner wall of shell 10
Fixed separator 30, need not be described in detail herein.
Further, the separator 30 includes partition, and the ventilation device includes the multiple ventilations being opened on partition
Hole.The rear operatic tunes 52 is isolated into vibration cavity 521 and sound absorption cavity 522 in this way, can realize by setting partition, passes through setting and ventilates
Hole is, it can be achieved that connection sound absorption cavity 522 and vibration cavity 521.Moreover, being arranged by above structure, it may make that 30 structure of separator is simple
It is single, easy to make.
It is appreciated that the ventilation device only should allow gas to pass through, without allowing sound-absorbing material etc. to pass through, that is, ventilate
Structure has the characteristic of ventilation resistance object.Therefore when sound-absorbing material is sound-absorbing particle, the size of sound-absorbing particle should be greater than venthole
Size.
Further, multiple ventholes are uniformly distributed on partition, or by default rule distribution.In this way, suction can be improved
Audio fruit.
Optionally, for multiple ventholes in N row * M column arrangement, the spacing between each row is equal, the also phase of the spacing between each column
Deng.
Optionally, multiple ventholes are placed with N row, and the venthole between adjacent rows is staggered.
In the present embodiment, the partition is set as metal plate.
Specifically, the partition can injection molding, can also be stamping parts, can also be for profile etc..
In other embodiments, the material of the partition may be alternatively provided as other nonmetallic materials, for example, the partition can
Think plastic plate, injection molding.
In the second embodiment of the separator 30, as shown in Figure 6 and Figure 7, the separator 30 includes bulkhead 32, institute
State the air-permeable member 33 that ventilation device includes the blow vent 321 being opened on bulkhead 32 and the blow vent 321 for being installed on bulkhead 32.Such as
This can be easily installed air-permeable member 33, can save cost, be conducive to batch production by being arranged air-permeable member 33 on bulkhead 32.
In this embodiment, the blow vent 321 may be provided with one, length direction of the blow vent 321 along bulkhead 32
It is extended；Alternatively, the blow vent 321 may be provided with multiple, multiple blow vent 321 is along the length direction interval of bulkhead 32
Arrangement, and each blow vent 321 is correspondingly arranged an air-permeable member 33；Alternatively, the blow vent 321 may be provided with multiple, this is more
A blow vent 321 is intervally arranged along the length direction of bulkhead 32, and air-permeable member 33 is provided with one, which covers all
Blow vent 321；Etc..
In this embodiment, the bulkhead 32 can be metal frame, at this point, bulkhead 32 can injection molding, can also be punching press
Part can be also profile etc.；Certainly, the bulkhead 32 may be alternatively provided as other nonmetallic materials, for example, the bulkhead 32 can be
Frame of plastic, injection molding.
In this embodiment, specifically, the air-permeable member 33 and 32 integrated injection molding of bulkhead.So, it is possible to increase ventilative
The bonding strength (firmness combined) of part 33 and bulkhead 32, so as to enhance the durability of separator 30.
Certainly, in this embodiment, the air-permeable member 33 can also pass through two-sided glue connection or its other party with bulkhead 32
Formula, such as other glued modes or ultrasonic bonding mode or hot melting way etc., connection will not repeat them here.
In this embodiment, in order to improve the firmness that air-permeable member 33 is combined with bulkhead 32, reduce air-permeable member 33 from every
The risk being detached from frame 32, the air-permeable member 33 can be set to the side of the close sound absorption cavity 522 of bulkhead 32.And in order to increase sound-absorbing
The volume of chamber 522, further improves the acoustical behavior of loudspeaker mould group 100, and the air-permeable member 33 can be set to leaning on for bulkhead 32
The side of nearly vibration cavity 521.Both the above design method can be selected according to actual needs.Certainly, in order to further drop
The risk that low air-permeable member 33 is detached from from bulkhead 32 can set bulkhead 32 to the two sub- frames mutually spliced, air-permeable member 33 is pressed from both sides
Between the two sub- frame.
In this embodiment, the air-permeable member 33 may be either non-woven fabrics or screen cloth or nylon mesh grid or metal mesh etc.,
It can also be filter paper or Du Pont's paper or leaching membrane paper or reticulate pattern paper；But not limited to this, as long as being made or breathing freely form for ventilative material
, the purpose of ventilation resistance object can be realized.
The present invention also proposes a kind of mobile terminal, which includes loudspeaker mould group, as shown in Figures 1 to 10, should
