Embodiment
As shown in Figures 3 and 4, Microspeaker of the present invention, includes reticulate body 10, conductor 20 and a pedestal 30.
Reticulate body 10, which is provided with grid (not indicated in diagram).Conductor 20, be positioned at below reticulate body 10, and be formed with a spacing between reticulate body 10, relative to reticulate body 10 lower position on conductor 20, be formed with a perforation 21, its 21 inside of boring a hole are provided with multiple T-shaped stator 22, and those T-shaped stators 22 bend slightly along reticulate body 10 direction, and the periphery convex of conductor 20 is provided with and is embedded sheet 23, its conductor 20 be embedded sheet 23 and be positioned on non-same plane.In the present embodiment, be embedded sheet 23 to be formed to inclination extension outward by the periphery of conductor 20.
Please coordinate shown in Fig. 5, pedestal 30, be then be shaped between reticulate body 10 and conductor 20 with injection molding method, and in order to fixing reticulate body 10 and conductor 20, the sheet 23 that is embedded of its conductor 20 is embedded in pedestal 30, makes being exposed on pedestal 30 of conductor 20 part.And, pedestal 30 forms the sound channel tube wall 31 of a hollow, sound channel tube wall 31 by conductor 20 perforation 21 towards reticulate body 10 direction extend form, the T-shaped stator 22 of conductor 20 is embedded in the lower edge of sound channel tube wall 31, and reticulate body 10 is then the upper limb place being embedded at sound channel tube wall 31.
As shown in Figures 5 and 6, pedestal 30 is wherein utilized to be connected and fixed between reticulate body 10 and conductor 20, because pedestal 30 takes shape between reticulate body 10 and conductor 20 with injection molding method, therefore, overlapping contact area can be formed with between the periphery of reticulate body 10 with the sound channel tube wall 31 of pedestal 30, in the contact area of overlap, sound channel tube wall 31 has in the grid 11 being embedded in reticulate body 10 of part, so as to utilizing sound channel tube wall 31 to embed in the grid 11 of reticulate body 10, its reticulate body 10 is made effectively to be fixed on the upper limb place of the sound channel tube wall 31 of pedestal.
In the present embodiment, reticulate body 10 is fixed on the upper limb place of sound channel tube wall 31, the upper edge of its sound channel tube wall 31 and the upper edge roughly copline of reticulate body 10.But in practical operation, the upper edge of reticulate body 10 also can a little less than the upper limb of sound channel tube wall 31.
It is worth mentioning that, in the present invention, mainly pedestal 30 is taken shape on reticulate body 10 with injection molding method, the sound channel tube wall 31 of part is made to be embedded in the Partial Mesh 11 of reticulate body 10, therefore, reticulate body 10 can more efficientlyly be fixed on sound channel tube wall 31, not only can increase the structural strength of reticulate body 10 and sound channel tube wall 31, and the height of sound channel tube wall 31 also its demand visual, and first set in the ejection formation stage, the height of body sound channel tube wall 31 can be adjusted whereby along with user demand, and then meet the microminiaturized requirement of loud speaker.
And for example shown in Fig. 5 and Fig. 7 to Figure 10, for reaching the structure of above-mentioned Microspeaker, the manufacture method of Microspeaker of the present invention, comprises the following step:
Location: the reticulate body 10 with grid is positioned on a plate body 40, and plate body 40 is positioned on a tool 50, reticulate body 10 is positioned at above tool 50.Wherein, plate body 40 has at least one location hole 41, make its plate body 40 be able to by location hole 41 and be fixed on tool 50.
Mould closes: be placed in by tool 50 in one first die holder 51, this first die holder 51 is utilized to be fixed by plate body 40 with this tool 50, recycle one second die holder 52 to be combined with the first die holder 52, to be formed with a molding space 53, the surrounding of reticulate body 10 is made to be exposed in molding space 53, and utilize injection molding method to form in molding space 53 pedestal 30 that one has sound channel tube wall 31, reticulate body 10 is made to take shape on this sound channel tube wall 31, and between reticulate body 10 with sound channel tube wall 31, be formed with an overlapping contact area, in this contact area, sound channel tube wall 31 has in the grid of the embedding reticulate body 10 of part.
The demoulding: when after pedestal 10 cooled and solidified, then this pedestal 10 is taken off between the first die holder 51 and the second die holder 52.
Wherein, close in step at mould, except reticulate body 10 being fixed on except the first die holder 51, also conductor 20 is fixed on the second die holder 52, again the first die holder 51 and the second die holder 52 are given mould afterwards to close, and then make reticulate body 10 and conductor 20 have a part be exposed in molding space, after pedestal 30 ejection formation, conductor 20 and reticulate body 10 effectively can be fixed on pedestal 30.
In addition, when conductor 20 is fixed on the second die holder 52, the T-shaped stator 22 of conductor 20 and be embedded in molding space 53 that sheet 23 is also exposed between the first die holder 51 and the second die holder 52, thus when after pedestal 30 ejection formation, will to be fixed on pedestal 30 inner with being embedded sheet 23 for T-shaped stator on conductor 20 22, comes off on pedestal 30 to prevent conductor 20.
So as to, utilize above-mentioned manufacture method, except can effectively reticulate body 10 be fixed, pedestal 30 can be made one-body molded with shoot mode on reticulate body 10 simultaneously, structural strength between the sound channel tube wall 31 not only adding reticulate body 10 and pedestal 30 like this, also can avoid reticulate body 10 to come off on sound channel tube wall 31.
In addition, the height of sound channel tube wall 31, also adjusted by the degree of depth of molding space 53, when the degree of depth of molding space 53 is more shallow, the height after sound channel tube wall 31 is shaping is then lower; Otherwise, when the degree of depth of molding space 53 is darker, the height after sound channel tube wall 31 is shaping is then higher, utilizes injection molding method to reach integrated effect except making sound channel tube wall and reticulate body, also effectively can reduce the height of sound channel tube wall, and then reach the microminiaturized requirement of loud speaker.
