The upper cover 1 include with the lower cover 2 upper cover ontology 11 disposed in parallel, from the periphery of the upper cover ontology 11 to
The support level portion 12 and extend and accommodate from the upper cover ontology 11 to 2 direction of lower cover that 2 direction of lower cover extends
Supporting walls 13 in the accommodating space 10, the periphery of the lower cover 2 bear against the support level portion 12 and form sealing
It is fixed.For example, the upper cover 1 and the lower cover 2 form sealing by ultrasonic bonding and fix, gluing mode can also be passed through certainly
Or other means realize.The supporting walls 13 are used to support the fixed sounding monomer 3.
In conjunction with refering to Fig. 3, the sounding monomer 3 is contained in the accommodating space 10 and the supporting walls are fixed in support
13, the sounding monomer 3 and the upper cover 1 surround ante-chamber 101, are used for sounding.The sounding monomer 3, the lower cover 2 and institute
It states upper cover 1 and surrounds back cavity 102 jointly, for improving frequency acoustic performance.
The upper cover 1 further includes the first retaining wall 41, and first retaining wall 41 is prolonged from the upper cover 1 to 2 direction of lower cover
It stretches and is connected to the supporting walls 13.The lower cover 2 further includes the second retaining wall 42, second retaining wall 42 from the lower cover 1 to
2 direction of upper cover extends and is connected to first retaining wall 41.First retaining wall 41 and second retaining wall 42 sealing are solid
Determine and the back cavity 102 is separated into the first back cavity 1021 and the second back cavity 1022, fills sound-absorbing in second back cavity 1022
Grain (not shown), for example, the sound-absorbing particle is zeolite granular.
In present embodiment, first retaining wall 41 is equipped with after through-hole 40 thereon, the first back cavity 1021 and second
Chamber 1022 is communicated by 40 gas of through-hole.Certainly, second retaining wall 42 is also settable through through-hole 40 thereon, or
First retaining wall 41 and second retaining wall 42 are respectively provided with the through-hole 40 through thereon.
In present embodiment, the breathable barrier 6 is fixed on first retaining wall 41 and the through-hole 40 is completely covered.
The sound-absorbing particle is isolated from second back cavity 1022 by the breathable barrier 6, so that 1022 shape of the second back cavity
At the virtual operatic tunes, to increase propagation path of the sound wave in the space, effectively improve the low frequency of the loudspeaker enclosure 100
Acoustical behavior.It should be noted that the breathable barrier 6 allows air to pass through mutually circulation, but prevent other materials mutual
Circulation.
It is worth noting that, the through-hole through thereon is separately provided in second retaining wall, breathable barrier is completely covered
It in the through-hole of the second retaining wall, can equally increase airflow channel, promote frequency acoustic performance；Or first retaining wall and described
Two retaining walls are respectively provided with the through-hole through thereon, and breathable barrier is one or more, and first retaining wall and described is completely covered
The technical effect for promoting frequency acoustic performance equally may be implemented in the through-hole of second retaining wall.
Therefore, described since first retaining wall 41 is formed in upper cover 1 when the lower cover 2 is covered on the upper cover 1
Second retaining wall 42 is formed in lower cover 2, and first retaining wall 41 and second retaining wall 42 are connected and sealed fixed by the sound-absorbing
Particle is isolated from second back cavity 1022, by being set to the logical of first retaining wall 41 and/or second retaining wall 42
The breathable barrier 6 of hole 40 and the covering through-hole 40, had both effectively prevented the sound-absorbing particle to pass through the breathable barrier 6
Into first back cavity 1021, and airflow channel is increased, facilitates first back cavity 102 and second back cavity 1022
Gas circulation, improves frequency acoustic performance；The assembly process for saving acoustical cotton 5 and acoustical cotton 5 simultaneously, reduces and is produced into
This, improves production efficiency.
In present embodiment, first retaining wall 41 and second retaining wall 42 form sealing by ultrasonic bonding mode
It is fixed.Keep the sealing fixed performance of first retaining wall and second retaining wall more stable by ultrasonic bonding mode.When
So, fixation can be also otherwise sealed in first retaining wall 41 and second retaining wall 42.For example, in first retaining wall
It is filled out between 41 and second retaining wall 42 and sets sealant, first retaining wall 41 and second retaining wall are made by the sealant
Sealing is formed between 42.Specifically, sealant can be glue-line or the foam of filling etc..Wherein, the sealing formed by glue-line
Layer, cost is relatively low, and sealing fixed effect is preferable.
Specifically, the breathable barrier 6 is attached at the close institute of first retaining wall 41 and/or second retaining wall 42
State the side of the first back cavity 1021.The position setting of the structure increases the effective volume of second back cavity 1022, further
Improve frequency acoustic performance.
More specifically, the breathable barrier 6 passes through injection molding manner and first retaining wall 41 and/or the second gear
Wall 42 is integrally formed.The assembly for improving first retaining wall and/or second retaining wall and the breathable barrier as a result, is imitated
Rate improves Forming Quality.
In present embodiment, the lower cover 2 part corresponding with the sounding monomer 3 includes first area 21 and the secondth area
Domain 22, the first area 21 form the first gap 7, the second area 22 and the sounding with the sounding monomer 3 interval
The interval of monomer 3 forms the second gap 8, and the height in first gap 7 is greater than the height in second gap 8；Between described first
Acoustical cotton 5 is filled in gap 7, and second back cavity 1022 and first back cavity 1021 formation are made by the acoustical cotton 5
Air communication, second gap 8 form fixing seal by filling glue.To in first retaining wall 41 and described second
Retaining wall 42 formed sealing it is fixed when, by the acoustical cotton 5 that is filled in first gap for first back cavity 1021 with
Second back cavity, 1022 air communication, and obstruct sound-absorbing particle and enter first back cavity from second back cavity 1022
1021, further to improve frequency acoustic performance.
Compared with the relevant technologies, the upper cover of the loudspeaker enclosure of the utility model is formed with the first retaining wall, the lower cover
Be formed with second retaining wall, first retaining wall and/or second retaining wall are equipped with the through-hole through thereon, it is described it is ventilative every
