Hardening time processed is so that silica gel reaches optimum adhesion state, thus reaching optimum adhesion effect.
Further, a part of lateral surface of the box wall of close speaker body of lower house arranges a tabular and go out line, go out
Some through holes are provided with line.
Further, go out the height more than the outer wall of lower house for the height of line.
It is preferred that upper shell is in the box-like of one end open, box-like box wall is provided with a peristome, in upper shell and
It is corresponding with the position going out line that lower house links into an integrated entity after-opening portion.
By such setting so that after the upper and lower casing combination of Mobile phone horn chamber device, the speaker body of mobile phone is just
The through hole that is aligned out in line so that the sound that spreads out of become apparent from loud.
A kind of encapsulating method using Mobile phone horn chamber as above device, comprises the steps:
Step one, starts point gum machine on the table by fixing for lower house, point gum machine according to program set in advance along
Groove on lower house carries out dispensing operation so that uniform pack expires liquid silica gel in groove；
Step 2, the lower house standing that dispensing is finished air-dries a period of time；
Step 3, upper shell is inverted in the top of lower house, presses together after upper shell and lower house justified margin；
Step 4, the persistently time of pressing one setting, until upper shell and lower house are bonded into one completely.
Wherein, in above-mentioned steps one, the charging quantity of silica gel is by program setting, and generally liquid level is slightly higher than groove
1～2 millimeter of mouth, makes silica gel not flow out outside groove using liquid level tension force.
In addition, in step 2, the air-dried time is also to be determined by different silica gel types.
Further, the dispensing operation in step one can also be by being accomplished manually.
Compared with prior art, technical solution of the present invention is provided with following beneficial effect:
Upper and lower two housings are connected by the Mobile phone horn chamber device of the present invention and its sealing means by the silica gel in groove
It is integrated, connect without using foam viscose, have the following advantages: one, prevent sealing foam crimp from leading to cavity gas leakage；
2nd, contrast echo ripple sealing means cost is more cheap；3rd, the thickness making Mobile phone horn device reduces, and makes mobile phone integral thinned；
4th, structure is simple, the suitability is wide.
