The pyramid type of inverted trapezoidal, cross section are the spherical etc. of cambered surface, it addition, described briquetting 32b can also according to be actually needed according to it
He sequentially arranges, as being staggered.
Please referring particularly to Fig. 9, before the raw material 24b added does not solidifies, press down on described press section 30b, described
The briquetting 32b of press section 30b is through the raw material 24b on described abatvoix 20b and compresses described abatvoix 20b, thus described
Some acoustics mouth 11b with described briquetting 32b mating shapes are formed on raw material 24b on abatvoix 20b and abatvoix 20b,
Each acoustics mouth 11b includes one first acoustics mouth 111b and the one second acoustics mouth connected with described first acoustics mouth 111b
112b, described first acoustics mouth 111b are formed at through the raw material 24b, described second acoustics mouth 112b on described abatvoix 20b
On described abatvoix 20b, described first acoustics mouth 111b, the second acoustics mouth 112b seamlessly transit.Pressing down on described pressing
During portion 30b, described briquetting 32b extrudes described raw material 24b, by described raw material 24b and described housing 10b, abatvoix 20b
Combine closely.Owing to described raw material 24b is consistent with the raw material of described housing 10b, therefore, described raw material 24b is combined with housing 10b
It is integrated and is formed housing 10 as shown in Figure 1.Move up described press section 30b so that it is depart from described housing 10b, i.e. make
Appearance becomes sound screening arrangement as shown in Figure 1.
It addition, as the sound screening arrangement in second embodiment of the invention need to be manufactured, if periphery the most only need to be provided to be formed
The abatvoix 20a (as shown in Figure 3) of dry rough outer lace 23a.In the process pressing down on described press section 30b
In, described briquetting 32b extrudes described raw material 24b, is combined closely with described housing 10b, abatvoix 20a by described raw material 24b, with
Time then form, at described raw material 24b, the interior lace (figure matched with described outer lace 23a near the part of described abatvoix 20a
Do not show).So, described outer lace 23a combines closely with interior lace, is conducive to being combined described abatvoix 20a with housing 10b
The most firm.
In tut screening arrangement manufacturing process, described press section 30b includes some briquetting 32b, described briquetting 32b's
Highly the vertical dimension more than described abatvoix 20a, 20b with described housing 10b upper surface, therefore, presses down on described pressing
During portion 30b, can form acoustic construction on described housing 10b and abatvoix 20a, 20b, not only manufacturing process is the most square simultaneously
Just, but also the sound screening arrangement with preferable erasure effect can be produced.
It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various
Corresponding change and deformation, and all these change and deformation all should belong to the protection domain of the claims in the present invention
Within.
