Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Please refer to Fig. 1-2, wherein, Fig. 1 is the dimensional structure diagram of loudspeaker enclosure of the present invention；Fig. 2 is the portion of Fig. 1
Sequential Stereoscopic structure decomposition figure.The invention provides a kind of loudspeaker enclosure 100, including lower cover 1, upper lid 2, sounding monomer 3, retaining wall 4,
Intercommunicating pore 5, breathable barrier 6 and filling hole 7.It should be noted that in the present invention, the upper lid 2 is and the sounding monomer 3
Sounding side is oppositely arranged.
Fig. 3 is please referred to, is the cut-away view of the line A-A along Fig. 1.The lower cover 1 assembles to be formed jointly with the upper lid 2
Receiving space 8.Specifically, the lower cover 1 forms fixing seal with the upper lid 2 by ultrasonic welding process.
The sounding monomer 3 is contained in the receiving space 8, and the sounding monomer 3 and the upper lid 2 surround ante-chamber 81,
For sounding；The sounding monomer 3 surrounds back cavity 82 jointly with the lower cover 1 and the upper lid 2, for improving frequency acoustic
Energy.I.e. described receiving space 8 is separated into the ante-chamber 81 and the back cavity 82 by the sounding monomer 3.
The retaining wall 4 is extended to the direction of the lower cover 1 from the upper lid 2 and is connected to the lower cover 1.The retaining wall 4 will
The back cavity 82 is divided into the first back cavity 821 and the second back cavity for forming the virtual operatic tunes for installing the sounding monomer 3
822.In present embodiment, the lower cover 1 includes being covered on the first lower cover 11 of first back cavity 821 and is covered on described the
Second bonnet 12 of two back cavities 822.
By to sound-absorbing particle (not shown) is filled in second back cavity 822, making second back cavity 822 form D-
The virtual operatic tunes of BASS, after sound enters second back cavity 822, increases its transmission path, for changing by the sound-absorbing particle
The audio performance of the kind loudspeaker enclosure 100, particularly frequency acoustic performance.Specifically, in present embodiment, the sound-absorbing
Grain is zeolite.
The intercommunicating pore 5 is set through the retaining wall 4, first back cavity 821 is connected with second back cavity 822.
In present embodiment, the intercommunicating pore 5 includes two, and reinforcement 51 is provided between two intercommunicating pores 5.More excellent, it is described
Intercommunicating pore 5 is rectangle.Certainly, its shape not limited to this, or other shapes, such as circle.In addition, the intercommunicating pore 5
An entirety is can be regarded as, i.e., two units is divided into by the reinforcement 51.
The breathable barrier 6 is fixed on the retaining wall 4 and the intercommunicating pore 5 is completely covered.It is more excellent, it is described it is ventilative every
Off member 6 is fixed on the side of close described first back cavity 821 of the retaining wall 4, and the structure setting can greatly increase
The volume of the virtual operatic tunes, improves audio frequency effect more excellent.
When the breathable barrier 6 is covered on two intercommunicating pores 5, the reinforcement 51 can be to the sound-absorbing particle
Stopped, i.e., the barrier effect to the breathable barrier 6 is strengthened, protection is formed to the breathable barrier 6 and is propped up
Support, while the center section of the breathable barrier 6 is securable to the reinforcement 51, to strengthen the breathable barrier 6
Fixing intensity, improves its stability.

When injection moulding integrated molding.Specifically, in injection molding processes, the breathable barrier 6 passes through die for inner sliding block (not shown)
With rear film die (not shown) sandwiched, then by injection molding process formed the intercommunicating pore 5 and the breathable barrier 6 with
The fixation of the retaining wall 4.In addition, be molded the breathable barrier 6 in the retaining wall 4 by aforesaid way so that described ventilative
The fastness and uniformity that the plastic cement of separator 6 and the retaining wall 4 is combined are preferable, and structural stability is strong.
It is of course also possible to be that the intercommunicating pore 5 is initially formed, by breathed freely described in die for inner sliding block and rear film die sandwiched every
Off member 6, then the fixation of the breathable barrier 6 and the retaining wall 4 is formed by injection molding process.This is also the same original
Reason.
More excellent, in present embodiment, the breathable barrier 6 is screen cloth, certain its not limited to this, as long as institute can be isolated
State sound-absorbing particle into first back cavity 821 and the entrant sound that can breathe freely.
The filling hole 7 is set through the upper lid 2, and the filling hole 7 connects with second back cavity 822, described
Sound-absorbing particle pours into second back cavity 822 by the filling hole 7, so that second back cavity 822 forms D-BASS
The virtual operatic tunes.
Compared with correlation technique, loudspeaker enclosure of the invention sets the retaining wall and the back cavity is divided into the installing hair
First back cavity of sound monomer and the second back cavity for forming the virtual operatic tunes, and the intercommunicating pore through thereon is set in the retaining wall
First back cavity is connected with second back cavity, the breathable barrier is fixed on the retaining wall, so that described
Second back cavity is completely formed the virtual operatic tunes, and it is not limited using volume by planform, this configuration avoids retaining wall and
The breathable barrier takes the volume of second back cavity, so that the relative volume that improve the virtual operatic tunes, by its volume pole
Bigization, so that the audio that improve the loudspeaker enclosure of high degree especially frequency acoustic performance.The breathable barrier
With the retaining wall injection moulding integrated molding after sliding block and caudacoria sandwiched mode are connected to the retaining wall, follow-up assembling work is saved
Skill, simple structure.
Above-described is only embodiments of the present invention, it should be noted here that for one of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
Enclose.
