Abstract
The invention provides a method for manufacturing a front cover of a sounder. The method comprises the following steps of: providing a metal planar cover top with a sound hole; providing a frame mould; combining the cover top with the frame mould; injecting high-pressure liquid-state plastic into the frame mould; performing injection molding to obtain a formed frame; and integrating the cover topwith the frame simultaneously. The size of the sound hole formed on the manufactured front cover of the sounder can be set according to requirements of product performance; the thickness of the frontcover of the sounder can be 0.1mm or less to realize miniaturization; and the shape of the front cover of the sounder can also be diversified. Furthermore, the sound inlet or outlet effect of the front cover of the sounder is improved, and the performance of a related product is improved.
Description
[technical field]
The present invention relates to a kind of manufacture method of protecgulum, relate in particular to a kind of manufacture method that is applied to the protecgulum in the minitype acoustic generator.
[background technology]
Minitype acoustic generator is widely used in the portable electronic equipments such as mobile phone, notebook computer, hearing aids.Along with fast development, the people of these portable electronic equipments are more and more stronger to its Functional Requirement, the mini-sound device that is applied thereon is corresponding rapidly development also.
The minitype acoustic generator of correlation technique comprises protecgulum, front framework and the caping of being covered with.The method of making front cover device is to adopt separately metal or plastic material moulding.If adopt separately metal material (being generally copper product) to make, because the restriction of material and molding mode, as adopt thin sheet-metal formed, i.e. stretch forming method, then the material at each position of protecgulum is thick identical, and the shape of product can be limited to some extent; As adopt thick sheet-metal formed, i.e. the method for extrusion modling, then protecgulum local location material can be extruded attenuation reaching required shape, and the restriction of the attribute of material itself and processing technology, weakened region can limit the size of offering hole; If adopting separately plastic material makes, as adopt injection molding, the shape of plastic shaping can be than the shape variation of metal forming, but product of the prior art is because the restriction of material and molding mode, the protecgulum thickness that the method is made can only be accomplished 0.25-0.3mm, can not satisfy far away product required microminiaturized requirement.
Therefore, being necessary to study a kind of new technology technical scheme improves or addresses the above problem.
[summary of the invention]
The technical problem that the present invention need solve provides a kind of manufacture method of acoustical generator front cover, the protecgulum that the method is produced, its size can be offered according to the Related product performance need in sound hole that it is provided with, and the thickness of protecgulum can accomplish that 0.1mm or thinner, its shape also can variations.
According to above-mentioned technical problem, designed a kind of manufacture method of acoustical generator front cover, the method comprises that the following step poly-:
A kind of manufacture method of acoustical generator front cover, the method comprises the steps:
The one metal plane caping that is provided with hole is provided, described caping is provided with main part, described main part is provided with sidewall, described sidewall is provided with some fixed parts, it comprise by described sidewall downwards extended the first fixed part and by described the first fixed part to away from extended the second fixed part of described main part direction, described the first fixed part also is provided with fixing hole; One frame mold is provided; Described caping is combined with described frame mold, injects the high-pressure liquid plastics in the described frame mold, the mode by injection mo(u)lding obtains shaping frame, and simultaneously one-body molded described caping and described framework.
Preferably, described fixed part is provided with four.
Preferably, also be provided with by the extended some projections of described sidewall between two adjacent described fixed parts.
Preferably, described metal is copper.
Compare with correlation technique, the acoustical generator front cover that the present invention produces, its size can be offered according to the needs of properties of product in the sound hole which is provided with; The thickness of acoustical generator front cover can be accomplished 0.1mm or thinner, to reach microminiaturized; The shape of acoustical generator front cover also can variation.And then improved advancing sound or going out sound effective value of acoustical generator front cover, improve the performance of Related product.
[description of drawings]
Fig. 1 is the acoustical generator front cover three-dimensional structure diagram of an embodiment provided by the invention.
Fig. 2 is the caping three-dimensional structure diagram of the acoustical generator front cover of an embodiment provided by the invention.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
Shown in Fig. 1-2, a kind of manufacture method of acoustical generator front cover 1, the method comprises the steps:
The one metal plane caping 3 that is provided with hole 32 is provided;
One frame mold (not shown) is provided;
In the present embodiment, fixed part 4 is provided with four.Also be provided with between two adjacent fixed parts 4 by sidewall 33 extended some projections 5.Above-mentioned fixed part 4 and projection 5 and fixing hole 411 all are in injection moulding process, and caping 3 and framework 2 can more firmly be combined into one.
In addition, metal described in the present embodiment is copper, certainly, also can be other metal material.
Injection mo(u)lding is so that the surfacing of acoustical generator front cover 1.Related product gauge after the assembling is stable, more conveniently pastes packing ring (not shown) at protecgulum 1.
Compare with correlation technique, its size can be offered according to the Related product performance need in its sound hole that is provided with of the sounding protecgulum that the present invention produces, the thickness of acoustical generator front cover can accomplish that 0.1mm or thinner, its shape also can variations, and then improved acoustical generator front cover and advanced sound or go out sound effective value, improve the performance of Related product.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
