【Embodiment】
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 describes, it is clear that described embodiment is only the part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained all other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
It please join shown in Fig. 1-3, the invention provides a kind of loudspeaker enclosure 100, including upper lid 1, be covered on the upper lid 1 simultaneously
It is collectively forming the lower cover 2 of receiving space 10, the sounding monomer 3 for being contained in the receiving space 10, supporting walls 4, through hole 5, speaks
Chamber 6 and sound absorption unit 7.
The receiving space 10 is divided into ante-chamber 101 and back cavity 102 by the sounding monomer 3.The ante-chamber 101 is used to send out
Sound, the back cavity 102 are used to improve frequency acoustic performance.
Upper lid 1 includes bottom wall 11 and bent from bottom wall 11 extending and having the side wall 12 of acoustic aperture 120, downward from bottom wall 11
The direction of lid 2 extend and be connected to the supporting walls 4 of lower cover 2 and extend from bottom wall to the direction of lower cover 2 and connect supporting walls 4 with
The connection wall 13 of side wall 12.The supporting walls 4, bottom wall 11 and side wall 12 define out the operatic tunes 6 jointly.Go out the operatic tunes 6 and go out acoustic aperture 120
Connection.
Specifically, the supporting walls 4 set stage portion 41, the stage portion 41 by the supporting walls 4 the close lower cover 2
A lateral upper direction of lid 1 be recessed to be formed.
The through hole 5 is set through the supporting walls 4.In present embodiment, the through hole 5 include at least two and mutually
It is arranged at intervals.It is of course also possible to it is independent one through hole 5 or multiple.
In addition, the structure setting can facilitate it is described go out the operatic tunes 6 in sound-absorbing material etc. is set, acoustic performance to improve.Than
Such as, in present embodiment, the sound absorption unit 7 be arranged at it is described go out the operatic tunes 6 in, preferably described sound absorption unit 7 is acoustical cotton.
The sounding monomer 3 is fixedly supported to the supporting walls 4 and forms institute with the interval setting of bottom wall 11 of the upper lid 1
The operatic tunes 8 before stating, the through hole 5 by the preceding operatic tunes 8 with it is described go out the operatic tunes 6 connect so that the preceding operatic tunes 8 and it is described go out the operatic tunes
6 are collectively forming the ante-chamber 101, for sounding.More excellent, in present embodiment, the support of sounding monomer 3 is fixed on described
Stage portion 41.
Because the sounding monomer 3 is supported in the supporting walls 4, then by adjusting the through hole 5 on the supporting walls 4
Size, then the preceding operatic tunes 8 can be made to be connected with full-size with going out the operatic tunes 6, and then it is more unobstructed that the preceding operatic tunes 8 is spoken,
Acoustical behavior is more excellent.
The sounding monomer 3 surrounds the back cavity 102 jointly with the lower cover 2 and the upper lid 1, for improving described raise
The frequency acoustic performance of sound device case.
It should be noted that the through hole 5 on the supporting walls 4 set at least two and it is spaced when, equivalent to
A retaining wall will be set up between the two neighboring through hole 5, can effectively prevent the sound absorption unit 7 from entering the preceding operatic tunes 8 and shadow
Ring the normal work of the sounding monomer 3.Certainly, the through hole 5 can be also arranged to one and its size is less than the suction
The size of sound unit 7, this can also reach same purpose, and its principle is all.
In order to realize the seal isolation of the ante-chamber 101 and the back cavity 102, in present embodiment, the supporting walls 4,
Side wall 12 and connection wall 13 are equipped with welding bar 9 and by the welding bar 9 and the lower cover close to the side of the lower cover 2
2, which form sealing, fixes, it is achieved thereby that seal off the ante-chamber 101 and the back cavity 102 simultaneously.
Compared with correlation technique, loudspeaker enclosure of the invention, which is set, covers the supporting walls extended to lower cover direction and formation from above
In the operatic tunes that goes out of upper lid, the sounding monomer support is fixed on the supporting walls and surrounds the preceding operatic tunes with upper lid, it is described go out the operatic tunes
Interior setting sound absorption unit, improve the acoustical behavior of loudspeaker enclosure；In addition, by the supporting walls set through hole make it is described before
The operatic tunes with it is described go out the operatic tunes connect so that the preceding operatic tunes can be connected with Breadth Maximum described in go out the operatic tunes so that the preceding sound
Chamber is spoken more unobstructed, and acoustical behavior is more excellent.
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 the protection model of the present invention
Enclose.
