Technical field:
The utility model relates to a kind of waterproof construction with microphone apparatus, handheld device such as mobile phone especially, the waterproof construction of microphone position.
Background technology:
Equipment such as existing waterproof mobile phone all adopt the waterproof microphone, but the waterproof measure of microphone and equipment room; Consider seldom that but traditional way promptly is that the contact-making surface at microphone and apparatus casing imposes colloid; Through colloid water-proofing treatment in addition; But this kind way is unfavorable for later period maintenance, and when assembling, and the difficulty of applying glue operation is also bigger.Moreover the water proof equipment of employing waterproof microphone often is difficult to adopt airtight appearance, carries out the test of sealing property, causes production process to detect, and causes the hidden danger of product.
Summary of the invention:
The purpose of the utility model is between a kind of microphone of design and apparatus casing, adopts the waterproof construction of the band microphone apparatus of packing element underbed reason seal approach.
The utility model technical scheme is achieved in that a kind of waterproof construction with microphone apparatus; Comprise the housing of equipment and be installed in the microphone on the housing; The place, pickup hole of the corresponding microphone of housing offers penetrable sound hole, it is characterized in that the disjunctor on every side of shell inner surface penetrable sound hole has a jacket casing, and interference is embedded with the packing element pad of a band through hole in the jacket casing; The through hole of this packing element pad aligns with penetrable sound hole on the housing, and between the contact-making surface of said packing element pad and jacket casing bottom, also is provided with a waterproof membrane; The microphone front is squeezed on the described packing element pad end face, keeps microphone pickup hole to align with the through hole of packing element pad.By the packing element pad of interference fit, eliminate microphone and apparatus casing fit-up gap, reach waterproof.
Said microphone is embedded in described jacket casing, and the front is squeezed on the described packing element pad end face, and rearward end is provided with the marine glue seal, the peristome of this marine glue seal sealing jacket casing, and the electrical lead that is located at the microphone bottom passes described glue seal.This structure is sealed in microphone in the separate space of apparatus casing, and the equipment finished product of making can adopt airtight appearance test.
The microphone of said bottom solid welding on circuit board is embedded in the packing element pad, and said packing element pad end disjunctor has a ring flange, and this ring flange is compressed between jacket casing end face and circuit board.This programme is applicable on the ultra-thin equipment and uses, even the microphone air-tightness is not enough, also can push the ring flange of packing element pad end by circuit board, forms regional waterproof and air-tightness, satisfies and adopts airtight appearance to the equipment waterproof test.
The length of through hole is utilized packing element pad through-hole surfaces tension force to solve and is reached waterproof effect greater than the diameter of through hole on the said packing element pad.
Said packing element pad is coated with non-hydrophilic coating in through-hole surfaces at least.Increase the tension force of through-hole surfaces, improve classification of waterproof.
Said packing element pad is made by non-hydrophilic latex or rubber.
The utility model increases a packing element pad and a waterproof membrane between microphone and apparatus casing, both eliminated the fit-up gap, again through waterproof membrane and the dual waterproof measure of packing element pad through hole, reaches the purpose of physical structure waterproof; And by microphone end face extruding packing element pad; And adopt the housing separate space to assemble microphone; Perhaps the way of the circuit board of solid welding microphone extruding packing element pad improves the air-tightness grade, so that the water proof equipment manufacture process; Can adopt airtight appearance to carry out the waterproof simulation test, solve the difficult problem of present water proof equipment test.

Embodiment:
With reference to Fig. 1, this is an embodiment preferred, the waterproof construction of band microphone apparatus; Comprise the housing 1 of equipment and be installed in the microphone 2 on the housing; Housing 1 is installed on the position of microphone 2, and place, the pickup hole of corresponding microphone 2 offers penetrable sound hole 11, and disjunctor has a jacket casing 12 around the housing 1 inner surface penetrable sound hole 11; Interference is embedded with the packing element pad 3 of a band through hole 31 in the jacket casing 12
The through hole 31 of this packing element pad 3 aligns with penetrable sound hole 11 on the housing, forms transaudient passage, and the length of this through hole 31 both can increase waterproof tension force greater than the diameter of through hole 31, also can improve anti-noise ability; Between the contact-making surface of said packing element pad 3 and jacket casing 12 bottoms, also be provided with a waterproof membrane 4, the first road waterproof barrier is provided, and this waterproof membrane 4 is to be close to through hole 31 front ends; Just through hole 31 forms an air cavity, even immerse in the water, also can in through hole, form the bubble of liquid such as an isolated water; As long as microphone 2 good seal performance own; The perhaps ventilative gap of the nothing between parts such as microphone 2 and circuit board, this " bubble " exists among the through hole 31 all the time so, and fluid partitioning gets in the microphone 2.
For this reason; Also need encapsulation process is carried out in microphone 2 other installation sites, like figure, microphone 2 fronts are squeezed on described packing element pad 3 end faces; Keep the pickup hole of microphone 2 to align with the through hole 31 of packing element pad; So that let sound wave pass smoothly, and microphone 2 and the 3 end face crush seals of packing element pad are avoided leaking gas and leaking.This structure, microphone 2 directly are welded on the circuit board 5, and circuit board 5 is fixed on the housing 1 extruding force of formation during by assembling.In addition, the fit-up gaps of microphone 2 itself exist, and possibly cause electrical lead 21 or electrode poorly sealed, can impose a fluid sealant 5 of microphone 2 shells and circuit boards for this reason, handle as dripping glue, let both gaps of glue infiltration.
