Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, each execution mode of the present utility model is explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the utility model, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First execution mode of execution mode of the present utility model relates to a kind of electronic equipment, as depicted in figs. 1 and 2.This electronic equipment, comprises: housing 1, circuit board 2, microphone MIC3 and sealing foam 4; Housing 1 is formed with the containing cavity 5 and leading note groove 6 that are interconnected; MIC3 is fixed on circuit board 2 and is positioned at containing cavity 5; Sealing foam 4 to be held between housing 1 and circuit board 2 and around MIC3.Wherein, leading note groove 6 is for importing microphone by external sound.
In present embodiment, sealing foam 4 has good elasticity and wettability, makes containing cavity can elastic packing.Sealing foam 4 is easy to fabrication design and cost is lower, the better effects if of the more general hermetically-sealed construction of sealing effectiveness.Housing 1 is formed with the containing cavity 5 and leading note groove 6 that are interconnected; By MIC3 being fixed on circuit board 2 and being positioned at containing cavity 5; And sealing foam 4 to be held between housing 1 and circuit board 2 and around MIC3, thus form MIC3 sound chamber that is complete, sealing, so housing 1 and circuit board 2 only need be carried out sealing the sealing that just can realize MIC3 sound chamber with sealing foam 4 by present embodiment, avoid Lou sound, sealing means is comparatively simple, and cost is lower.
In addition, have between the upper surface of MIC3 and the inner face of containing cavity 5 and keep away bit space, MIC3 can be avoided to occur souffle problem.It is worth mentioning that, height H 1 scope of keeping away bit space is 0.35mm to 1mm.Those skilled in the art find in actual test process, if the height H 1 of keeping away bit space is less than 0.35mm, MIC3 can be caused to occur the problem of noise, and are not easy to assembling.MIC3 audio can be caused bad if the height H 1 of keeping away bit space is greater than 1mm, and the installation of MIC3 also can take more space.So preferred, height H 1 scope of keeping away bit space in present embodiment can select 0.35mm; Thus both can MIC3 be avoided to a certain extent to occur souffle problem, the installing space of MIC3 can also be saved.But it is worth mentioning that; based on the relevant consideration of the size of all parts in actual design process, size and each component function; the altitude range keeping away bit space in present embodiment is not limited to the above number range enumerated; as long as MIC3 can be avoided to occur noise; and ensure other numerical value keeping away bit space height going out audio fruit of MIC3, also should within protection range of the present utility model.
In present embodiment, there is between MIC3 and sealing foam 4 preset pitch H2, be convenient to the installation of MIC3 and sealing foam 4.It is worth mentioning that, the scope of preset pitch H2 is 0.4mm to 1mm.Those skilled in the art find in actual test process, if preset pitch H2 is less than 0.4mm, when being arranged around MIC3 by sealing foam 4, not only can cause installing inconvenience, and the audio of MIC3 can be caused bad.MIC3 audio can be caused bad if preset pitch H2 is greater than 1mm, and its installation also can take more space.So preferred, in present embodiment, preset pitch H2 gets 0.4mm.Thus, not only make the installation of sealing foam 4 and MIC3 more for convenience, and souffle problem can be occurred to a certain degree avoiding MIC3, the installing space of MIC3 can also be saved.But it is worth mentioning that; based on the consideration of the size of all parts in actual design process, size and each component function; predeterminable range H2 in present embodiment between MIC3 and sealing foam 4 is not limited to the above number range enumerated; as long as MIC3 can be avoided to occur noise and ensure other numerical value that MIC3 can install very easily with sealing foam 4, also should within protection range of the present utility model.
In present embodiment, the width H3 of sealing foam 4 is more than or equal to 0.85mm; Preferably, the width H3 of sealing foam 4 is 0.85mm; Thus, the sealing effectiveness of circuit board 2 and housing 1 can be made better, and can well ensure that MIC3's goes out audio fruit.It should be noted that, if sealing foam 4 is annular, so the width H3 of sealing foam 4 refers to the difference of the outer radius of sealing foam 4 and the inside radius of sealing foam 4.
In present embodiment, electronic equipment can be mobile phone, or can be able to be notebook computer etc. for panel computer.For smart mobile phone, housing 1 is the procapsid 1 of smart mobile phone; Circuit board 2 is the platelet of smart mobile phone; Smart mobile phone also comprises the mainboard be connected with described platelet.
It should be noted that, the MIC3 of smart mobile phone can adopt diameter to be the SMD MIC of 4.0mm, and sealing foam 4 leaves 0.4mm safe distance with MIC3 is monolateral, and namely the inner side of sealing foam 4 and the distance of MIC3 periphery are 0.4mm.So the interior diameter of sealing foam 4 is 4.8mm, overall diameter 6.5mm.Thus only with sealing foam 4, the fore shell of smart mobile phone and circuit board 2 need be carried out sealing the sealing that just can realize MIC3 sound chamber, avoid Lou sound, sealing means is comparatively simple, and cost is lower.
Second execution mode of execution mode of the present utility model relates to a kind of electronic equipment, and present embodiment is improved on the basis of the first execution mode, and main improvements are: the binding site of sealing foam and circuit board is provided with mucigel; And/or the binding site of sealing foam and housing is provided with mucigel.
Specifically, the binding site of sealing foam and circuit board is provided with mucigel; Thus the combination of sealing foam and circuit board is more tight, and combination is comparatively simple, and cost is lower, and better tightness.The binding site of sealing foam and housing is provided with mucigel; The combination of sealing foam and housing is more tight, and combination is comparatively simple, and cost is lower, and better tightness.Sealing foam is held between procapsid and platelet, formed complete, sealing MIC3 sound chamber and sealing effectiveness is better.Wherein, the mucigel in present embodiment can be conducting adhesive cloth or conductive glue.But mucigel is not limited to conducting adhesive cloth or conductive glue, as long as the arbitrary form of the mucigel of combining closely of sealing foam and circuit board or sealing foam and housing can be realized, all should within protection range of the present utility model.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above realize specific embodiment of the utility model, and in actual applications, various change can be done to it in the form and details, and do not depart from spirit and scope of the present utility model.
