A kind of sound-producing device module disclosed by the invention, as illustrated in fig. 1-3, including module casing 1 and sound-producing device
Monomer 2.There is in module casing 1 accommodating chamber, sound-producing device monomer 2 to be arranged in accommodating chamber, by accommodating chamber be divided into back cavity with
Ante-chamber 11, i.e. ante-chamber 11 are enclosed by the inner wall 12 and sound-producing device monomer 2 of part module casing 1.Ante-chamber 11 is filled with sounding
The front for setting monomer 2 is corresponding, is used for external sounding.Coating, the structure of coating are provided on the inner wall 12 of part module casing 1
Agree with 12 phase of inner wall.Coating has the shiny surface of even curface and regular reflection sound wave towards the one side inside ante-chamber 11,
On the one hand, the module casing 1 formed relative to usual injection molding, the inner wall 12 for being molded formation is more coarse, when sound-producing device monomer 1
Front generate sound after, sound wave can form random diffusing reflection, the friction system of coarse inner wall 12 in coarse inner wall 12
Number and the audio of sound-producing device module can be all influenced on the absorption of sound, and the shiny surface of coating can effectively reduce it is coarse
Inner wall 12 friction coefficient, weaken the acoustic absorption of 12 pairs of coarse inner wall and the diffusing scattering to sound wave, can be further
Improvement sound-producing device module audio, promoted sound quality；On the other hand, certain in sound-producing device module overall structure, it keeps whole
In the case that body structure is constant, by the way that the shiny surface of coating formation rule reflection sound wave is arranged, it can also further improve hair
The audio of acoustic device module.
In some embodiments, coating, maximum limit can be both provided on the inner wall 12 of ante-chamber 11 by being enclosed in module casing 1
The audio of the improvement sound-producing device module of degree, promotes the sound quality of sound-producing device module.
In some embodiments, the material for forming coating is that can form the thin-film material of shiny surface, such as DLC materials,
That is DLC film material is a kind of noncrystalline membrane, is that one kind is made of carbon, is similar with diamond in nature, together
When again with graphite atom composed structure substance, have high rigidity and high elastic modulus, low friction coefficient is wear-resistant and good
Good vacuum tribological property is applied to ante-chamber as notable to the improvement of audio after coating material.
In some embodiments, the thickness of coating can be less than or equal to 10 microns, you can achieve the effect that improve audio,
And enough to the spacial influence of ante-chamber 11 is small.Due to the influence of material and processing technology factor, in other embodiments
In, the thickness of coating can also be to be capable of the shiny surface of formation rule reflection sound wave, the application is to this more than 10 microns
It is not intended to limit.
In some embodiments, the thickness of coating is approximately equal, the 11 structure phase contract of ante-chamber enclosed with inner wall 12
It closes.
In some embodiments, coating is sprayed on the inner wall 12 of part module casing 1 by spraying process, preferably
Be a spray mo(u)lding, reduce 12 different structure of inner wall at generate gap, as far as possible formed a continuous shiny surface,
Certainly, in various embodiments, for multiple parts mutually assembled it can not be once sprayed into since module casing 1 divides
When type, and can repeatedly spray mo(u)lding, the application is not intended to limit this.
In some embodiments, as illustrated in fig. 1-3, it is provided with sheet metal 13 on module casing 1.Sheet metal 13 is usual
It with 2 face of ante-chamber 11 and sound-producing device monomer, is covered on ante-chamber 11, since the intensity of metal is strong usually above injected plastics material
Degree, that is to say, that under same intensity, using sheet metal 13 come the side wall for replacing injected plastics material to be formed, the thickness of sheet metal 13
Degree is less than the thickness of the side wall of injected plastics material formation, and the wall thickness of module shell 1 is enabled to do by way of metal insert
To thinner, the space of ante-chamber 11 can be increased.Further, sheet metal 13 is towards being provided with coating, shape in the one side of ante-chamber 11
Improve audio at the shiny surface for capableing of regular reflection sound wave.
In some embodiments, as illustrated in fig. 1-3, there is acoustic aperture 14 on module casing 1, ante-chamber 11 and go out acoustic aperture
14 connections so that the sound that sound-producing device monomer 2 is sent out can be transferred to outside sound-producing device module.In some embodiments, preceding
Chamber 11 is connected to acoustic aperture 14 is gone out by the channel 15 of speaking in module casing 1, and the interior of channel 15 of speaking is enclosed in module casing 1
It is provided with coating on wall 12.
According to another aspect of the present invention, it the present invention also provides a kind of electronic equipment, has been used in electronic equipment above-mentioned
Sound-producing device module, can improve audio, promote sound quality.
Although some specific embodiments of the present invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to illustrating, the range being not intended to be limiting of the invention.The skill of this field
Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above example.This hair
Bright range is defined by the following claims.
