Summary of the invention
Technical problem to be solved by this invention is: the assembly method that place, a kind of loud speaker module sound hole nonmetal flexible net is provided, the one, in assembly method, used the nonmetal flexible net that thin thickness and mesh are little, water proof and dust proof and the acoustical behavior of acoustical device have been improved, the 2nd, make the assembling convenient operation of nonmetal flexible net, improved efficiency of assembling and assembly quality.
For solving the problems of the technologies described above, technical scheme of the present invention is: the assembly method of place, loud speaker module sound hole nonmetal flexible net, comprises the steps:
(1) nonmetallic flexible net material strip is cut into the flexible net monomer of setting shape;
(2) described flexible net monomer is put into front mould, the position contacting with described flexible net monomer on described front mould is provided with suction hole, in described front mould, be provided with the air intake passage being communicated with described suction hole, described air intake passage is connected with vacuum extractor, opens described vacuum extractor and vacuumizes described flexible net monomer absorption fixing to described suction hole place;
(3) front mould and rear mold are closed to film, to carrying out injection moulding in mold cavity, obtain the loud speaker module casing that the periphery with described flexible net monomer combines, described flexible net monomer is assemblied in the place, sound hole of loud speaker module.
As a kind of preferred technical scheme, described front mould is provided with front mould and enters son, described rear mold is provided with rear mold and enters son, described front mould enters son and described rear mold enters son and has the protuberance connecting, described suction hole is arranged on the end face that described front mould enters sub-protuberance, and the area of described flexible net monomer is all greater than the face area that described front mould enters sub-protuberance, the face area that described rear mold enters sub-protuberance.
As a kind of preferred technical scheme, described flexible net monomer is nylon wire material.
As a kind of preferred technical scheme, the thickness of described flexible net monomer is 0.05～0.1mm, and the mesh aperture of described flexible net monomer is 0.03～0.05mm.
Adopted after technique scheme, the invention has the beneficial effects as follows:
In assembly method of the present invention, due to what adopt, be nonmetal flexible net, for example, can adopt nylon wire material, that therefore can do is thinner, and thickness can reduce to take up room in 0.05mm left and right, can not increase small product size; And it is very little that the aperture of its mesh can be done, can reach 0.03～0.05mm, can improve the water proof and dust proof performance of acoustical device, and corrosion can not occur, improve useful life and the reliability of acoustical device.
The present invention by arranging suction hole on front mould, on front mould, put into after flexible net monomer, first opening vacuum extractor vacuumizes the absorption of flexible net monomer fixing to suction hole place, then by front mould and rear mold mold-closing injection, obtain the loud speaker module casing that the periphery with flexible net monomer combines, be about to the place, sound hole that flexible net monomer is assemblied in loud speaker module.Above-mentioned assembly method, pass through Design of Dies, can realize the reliable location of flexible net monomer, solved flexible net due to softer, yielding, the problem that is difficult for assembling, has improved efficiency of assembling greatly, and by Shooting Technique, realizes the assembling of flexible net, high in conjunction with firmness, avoided the caducous problem of the bonding not firm appearance of flexible net in prior art.
Further, front mould enters son and rear mold enters son and has the protuberance connecting, suction hole is arranged on the end face that front mould enters sub-protuberance, the area of flexible net monomer is all greater than the face area of two protuberances, can be so that the edge of flexible net monomer imbeds in the shell of loud speaker module in injection moulding process, avoided generation burr, can be so that product appearance neat appearance.
