Description
[technical field]
The present invention relates to electroacoustic conversion art more particularly to a kind of adhesive and sounding for applying to portable electronic product
Device.
[background technique]
During the fast development of the portable electronic products such as mobile phone, requirement of the user to electronic product is increasingly
Height, waterproof are one of basic demands.The important component micro acoustic device of portable electronic product be most susceptible into
Water influences one of device.On acoustical device, vibrating diaphragm is the influence for being most susceptible to water again, because of Most current acoustical device
Vibrating diaphragm be made using composite plastic film, such as: hydraulic pressure make vibrating diaphragm occur can not reversed fold, to generate noise.
Prevent water from entering in mobile phone or acoustical device although people devise various structures, these structures of all having returned are multiple
The problems such as hydridization, cost improve, sound quality is lost.For this purpose, gradually beginning to use elastic preferably thermoplastic elastic bluk recombination in the industry
Film.Currently, being mainly TPEE using wide thermoplastic elastomer films.TPEE(Thermoplastic Polyester
It Elastomer), is the abbreviation of thermoplastic polyester elastomer, by polyester hard section (crystalline phase) and aliphatic polyester or polyethers (amorphous
Phase) soft segment block copolymer, 1972 by DuPont and Toyobo take the lead in exploitation and respectively with Hytrel, Pelprene for quotient
Mark commercialization.This material is with excellent mechanical strength, heat-resisting quantity and ageing-resistant performance and in high-end cable/tubing, vapour
The fields such as vehicle are widely used.
The microphone device of the relevant technologies includes the voice coil and adhesive of vibrating diaphragm, the driving diaphragm oscillations sounding, described
Voice coil, which is sticked, is fixed on the vibrating diaphragm, and the vibrating diaphragm includes vibration section and is sticked and is fixed on the top dome of the vibration section.The glue
Stick is used to be bonded admittedly to the voice coil and vibrating diaphragm realization to be adhesively fixed and realize the vibration section and the top dome
It is fixed.
However, TPEE is adhesively fixed together as the sound film with the voice coil in actual microphone device, certainly also
Have, the vibration section and the top dome are adhesively fixed together.In bonding process, encounter following predicament: with traditional PEEK, PEI,
The plastic films such as PPS, PEN, PET are different, because containing aliphatic soft segment in TPEE structure, cohesive force is not high, this is just determined
In adhesive contact to before solidifying in this period, small molecule in adhesive (such as diluting monomer, solvent etc., it is such as common
: (methyl) butyl acrylate, (methyl) hydroxy-ethyl acrylate, (methyl) hy-droxybutyl, (methyl) hydroxypropyl acrylate,
(methyl) acrylic acid tetrahydrofuran ester, (methyl) methyl acrylate, N, N- dimethylacrylamide, (methyl) acryloyl morpholine,
(methyl) acrylamide etc., ethyl acetate, toluene, dimethylbenzene, acetone, butanone, cyclohexanone, tetrahydrofuran, N, N- dimethyl sulfoxide,
N,N-dimethylformamide, halogenated alkane, petroleum ether, ether, ethylene glycol (two) butyl ether) it is easy to penetrate into these soft segment high scores
Between subchain, the sound film is caused to be swollen, therefore apparent deformation also occurs for the sound film, influences its appearance and dimensionally stable
Property；On the other hand, if conventional small molecule is substituted using the slightly larger small molecule of molecular weight in adhesive, although its permeability is able to
It reduces, but causes adhesive strength to be greatly reduced in default of interface binding power, the microphone device reliability declines to a great extent.
Therefore, it is really necessary to provide the new adhesive of one kind and microphone device to solve above-mentioned technical problem.

Transparent PMMA material, in addition one uses TPEE material, because the adhesive is easy to bonding PMMA substrate, therefore breaks ring group sheet
It is all to occur at the interface adhesive-TPEE.When sample preparation, the adhesive is coated in the end PMMA, and dock the end TPEE, slightly
Apply pressure and is solidified using ultraviolet light；In test process, the maximum, force that two stretching rods are pulled open is as the amount of adhesive strength
Change value, every group of three samples, results are averaged, then obtains following experimental result, see Table 4 for details:
The adhesive strength effect of the adhesive of 4 reference examples of table and embodiment
| Sample | Value of thrust/N (adhesive strength) | It is swollen situation |
| Reference examples 1 | 25.6 | Curling |
| Reference examples 2 | 17.5 | Obvious warpage |
| Reference examples 3 | 14.5 | Micro- warpage |
| Embodiment 1 | 23.5 | Micro- warpage |
| Embodiment 2 | 26.8 | Micro- warpage |
| Embodiment 3 | 24.2 | Micro- warpage |
| Embodiment 4 | 28 | Micro- warpage |
| Embodiment 5 | 20.1 | Micro- warpage |
The adhesive prepared in reference examples using conventional small molecule diluent, although the adhesive bonding force is strong,
There is a problem of that swelling is obvious；And the higher diluting monomer of molecular weight is used alone, swelling is small, but bonding force is relatively low.?
The appropriate acidic materials of addition that this patent proposes in embodiment reach adhesive strength under the premise of unobvious generation swelling
Higher level.
Fig. 1-5 is please referred to, the present invention also provides a kind of microphone devices 100, including vibrating diaphragm 1, the driving vibration of vibrating diaphragm 1 hair

It states adhesive 3 and the vibration section 11 is pasted and fixed；The voice coil 2 is fixed on the vibration section 11.
Compared with the relevant technologies, adhesive of the invention is by component proportion and selects the biggish monomer of molecular weight, solves
The vibrating diaphragm is swollen big problem；On the other hand, the adhesive uses the acid, to make the bonding of the adhesive
Property significantly improves.After the adhesive is used for the microphone device, i.e., the described voice coil is pasted solid by the adhesive
Due to the vibrating diaphragm, the acoustical behavior and reliability of the microphone device can be effectively improved.
Above-described is only embodiments of the present invention, it should be noted here that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, improvement can also be made, but these belong to protection model of the invention
It encloses.
