Metal button panel 218 can comprise the metal boss 230 that is welded to downward opposed face 234.Metal boss 230 can be used for being attached to the intraware such as printed circuit board (PCB) (PCB in other words) to metal button panel 218 (together with a wheel trolley accessory 200).During assembling work, lug 232 can be used for being fixed to intermediate plate accessory 300 selecting wheel trolley accessory 200.For example, lug 232 capable of using snaps into metal button panel 218 to intermediate plate accessory 300.Like this; Metal button panel 218 can be considered to have double duty; Wherein the surface 220 of metal button panel 218 can be used for supporting annular button accessory 202; And the surface 234 shown in Figure 11 can be used for the assembly of metal boss 230 supports such as printed circuit board (PCB) by welding, and supports intermediate plate accessories 300 by lug 232.Connector 236 can be used for making flexible connector 228 to be electrically connected with electric component such as MLB.In addition, opening 238 is aligned in the opening 112 that forms in the shell 100.Like this, securing member capable of using directly is fixed to shell 100 to metal button panel 234 at least.

Figure 12 illustrates the embodiment of intermediate plate accessory 300.Before being used to accomplish the assembling of media player 10, intermediate plate accessory 300 can assembled in advance and test.Securing member 302 assembled in advance intermediate plate accessories 300 capable of using.Securing member 302 can be taked the form of screw 302.Screw 302 can be used for being installed to clamping plate 34 on the torsion spring piece 32 that holds torsion spring 304.Down, torsion spring 304 can make intermediate plate 30 compress clamping plate 34 in off position.Utilize with metal button panel 218 on the hook feature 306 that engages of lug 232, can be attached to intermediate plate accessory 300 on the metal button panel 218.Attachment features spare 308 can take to be bonded on the form of the hook of the opening 240 that forms in the metal button panel 218.

As shown in Figure 13, seal 310 can use the waterproof material such as silicon rubber to form.Near the flange 114 that forms about opening 106, seal 310 can be processed to the shape that conforms to the opening 106 of shell 100.Near flange 306, seal 310 can be placed on the shell 100.Like this, seal 310 can prevent that moisture or other liquid from invading the inside of shell 100 from external environment condition.Because existence forms the various openings that potential moisture is invaded path separately in shell 100, so this is even more important.

Can be according to shell 100, especially opening 106 is confirmed the size and the shape of seal 310.Seal 310 can be shaped as and stop moisture to invade the inside of shell 100, especially invades having of shell 100 and supplies to be exposed in those parts of opening of usefulness of the input unit (such as button or switch) in the external environment condition.For example, the opening in the seal 310 can be corresponding to the battery that is used for to media player 10 power supplies.On the other hand, opening 314 can corresponding to battery and the main logic plate (MLB) put.Since MLB comprise maybe be not water-fast many electric components, therefore compare with part 312, part 314 can be configured to provide waterproof barrier more reliably.

Between the erecting stage of media player 10, seal 310 can directly be placed on the flange 114 of shell 100.In case in place, just can directly directly place intermediate plate accessory 300 on the seal 310, and intermediate plate accessory 300 is exerted pressure.The pressure that puts on intermediate plate accessory 310 can make the lug 224 and attachment features spare 308 of hook 306 jointing metal button panels 218, thus coupling opening 240.Like this, can be so that invade the minimized mode of moisture of the inside of media player 10, make and select wheel trolley accessory 200 and be attached to each other securely with intermediate plate accessory 300.Be installed to the requirement on the shell 100 to intermediate plate accessory 300 through the securing member of above-mentioned use such as screw, do not have any observable securing member, thus to media player 10 provide totally, effective outward appearance.

Owing to the small size and the compactedness of media player 10, the influence of invading the moisture in the media player 10 can have serious consequence.For example, part even a spot of moisture also can form leakage path between assembly, causes function to reduce or even infringement owing to the high assembled density of the intraware in the media player 10.Therefore in media player 10, exist vacant space to cause moisture to cause when the possibility of infringement is higher hardly, especially true.Except invading the infringement possibility that causes because of moisture, the infringement that comes from static discharge (ESD in other words) is also serious.Equally, owing to small size and compact geometry, it is too high that electric field strength can become, so that sizable voltage peak possibly take place.Sensing assembly in considering MLB and the external switch such as playlist buttons 44 and hold button 38 extremely near the time especially true.Contact-making switch only, the user who perhaps even only picks up media player 10 just causes static discharge probably, and said static discharge might cause electric injury to the electric component of many sensitivities.Thereby esd protection is in the design of media player 10 and the significant consideration aspect the layout with stoping moisture/pollutant to be invaded.

Figure 14 illustrates main logic plate (MLB) accessory 400 according to embodiment.MLB accessory 400 can comprise MLB 402.Above can comprising, MLB 402 installs and is electrically connected the printed circuit board (PCB) (PCB) 404 of a plurality of integrated circuits 406.Integrated circuit can comprise at least one microprocessor, semiconductor (for example flash) memory, various support circuit or the like.By electric connector 410, the battery 408 that is connected with PCB 404 can be supplied power to integrated circuit.Battery 408 can be a lithium ion battery.Also show playlist contact-making switch 412 and keep in touch switch 414 with " side starts (side firing) ".Should notice that term " side startup " intention expression part owing to layout consideration and component density, can make maintained switch 38 depart from the thought of the position of keeping in touch switch 414.Like this, armature (armature) (following more detailed description) can connect maintained switch 38 and keep in touch switch 414.Connector 416 can be in the contact 236 be connected with flexible connector 228.In one embodiment, connector 416 can be zero insertion force as known in the art (ZIF) connector.Opening 418 can be aimed at the metal boss 230 of welding, but and be sized to admit land used to be fixed to a securing member of wheel trolley accessory 200 to MLB accessory 400, such as screw.Like this, securing member can firmly connect MLB accessory 400 and some wheel trolley accessory 200.

MLB 402 can comprise audio jack accessory 420, by audio jack main body 422, can be surface mounted to audio jack accessory 420 on the PCB 404.Audio jack accessory 420 can comprise the audio jack tube 424 integrally formed with audio jack main body 422, makes audio jack main body 422 have suitable size respectively, and places on the PCB 404, with the opening in the alignment housings 100 106.Like this, audio jack tube 424 can be admitted the audio jack terminal by audio jack port 42, and the audio jack terminal has the electric contact of aiming at and being electrically connected the expose portion of audio jack contact 426, like what in Figure 15 and 16, more specify and illustrate.More particularly, Figure 15 illustrates the end view of audio jack accessory 420, shows the relative position of audio jack contact 426 with respect to audio jack tube 424, audio jack main body 422 and PCB 404.In the illustrated embodiment, audio jack contact 426 can comprise the part 427 that embeds in the audio jack main body 422.But, in order to realize and the excellent electric contact of corresponding electric contact on the audio jack terminal that inserts audio jack port 42 that the audio jack contact 426 of a part can be exposed to the inner chamber 428 of audio jack tube 424 with the form of audio jack pad 430.

Should notice that inner chamber 428 can be directly exposed under the external environment condition that comprises quite a large amount of pollutants and moisture.So, any path of taking every caution against error and possibly allow pollutant and moisture to pass through between the inside of taking chamber 428 and media player 10 into account.Correspondingly, passage 432 can be considered to connect audio jack pad 430 and be surface mounted to the contact terminal 434 of the circuit 438 on the PCB 404 and the potential flow channel between the inner chamber 428 through PCB opening 436 being used to of arranging.

In order to prevent, perhaps make pollutant and moisture invade the minimizing possibility of inner chamber 428 at least, can use moisture barrier strict restriction (not stoping fully) pollutant and/or moisture directly to flow along any of passage 432 even be not.Moisture barrier can comprise a more than assembly.For example, in order to limit or eliminate moisture or pollutant, can in passage 432, comprise a plurality of water flow barriers along the possibility that passage 432 leads to media player 10 inside.In one embodiment, in the mounted on surface process, can fill PCB opening 436 with scolder, said scolder is used to make splicing ear 434 to be electrically connected with electric trace on the PCB 404.As the part of standard assembling process, PCB 404 can experience the fluctuation soldering, thereby scolder is flowed on the surface of PCB404.Flowing of scolder can be filled PCB opening 436 by capillarity.Capillarity have sealing possibly be present in PCB 404 and splicing ear 434 at the interface and the effect that possibly be present in any gap between audio jack main body 422 and the splicing ear 434.

Perhaps except scolder, other moisture barrier that can be included in the passage 432 can comprise stratiform thing 440 to the replacement scolder at least.Stratiform thing 440 can be with the material that the flows formation that is very suitable for intercepting moisture or pollutant.For example, stratiform thing 440 film that can take to conform to the profile of audio jack tube 424 and audio jack main body 422 or the form of adhesive tape (such as Kapton and Mylar).For example, water flow Obstruct membrane 440 is directly contacted with audio jack main body 422 with audio jack tube 424, extend to the zone that covers the maintenance district, contact 442 shown in more detail Figure 16.In some cases, in order to ensure film 440 basically with the shape-consistent of audio jack tube 424 and audio jack main body 422, possibly need jointing material.For example, can on film 440, adhesive layer be set, force film 440 to conform to the surface characteristics of audio jack tube 424 with audio jack main body 422.When film 440 approached and possibly send out wrinkle, it can be useful especially that adhesive is set on film 440.Any gap itself between film 440 and audio jack main body 422 and the audio jack tube 424 can form the additional via that the branch/pollutant that supplies water is invaded media player 10 inside.In order to ensure conforming to fully, and farthest stop moisture and pollutant to flow into media player 10 inside, contact terminal 434 can pass film 440, thereby further stops flowing of moisture/pollutant between the inside of inner chamber 428 and media player 10.

In another embodiment, the water flow barrier can be taked the form such as the class formation of lid 444, and this class formation can be directly mounted on the audio jack accessory 420, as shown in Figure 17.Lid 444 can form with waterproof material, and said waterproof material available heat forming technology forms, thereby has the shape that conforms to audio jack accessory 420.Especially, lid 444 can comprise opening, and the contact terminal 434 and erection column 446 that is used for attached audio jack accessory 420 and PCB 404 is arranged to hold in the size of said opening and position.In some cases, advantageously utilize adhesive to be fixed to audio jack accessory 420 to lid 444.Can in assembling process, place and fixed cover 444.Because the shape of lid 444 has been processed to conform to the profile of audio jack accessory 420, therefore in fact can eliminate the possibility that occurs the gap between lid 444 and audio jack main body 422 and the audio jack tube 424.Like this, under the situation of using lid 444, need not work as any wrinkle resistant measure required when using film 440.

For whether the inside of keeping watch on media player 10 is exposed under the moisture, can arrange a plurality of moisture indicators in media player 10 inside.When moisture contacted with it, one of the most frequently used moisture indicators provided the vision indication usually through changing color (for example, becoming redness from white).Through checking port organization, can check said vision indication.Like this, can easily discern any moisture invades.Be directly exposed under the external environment condition owing to audio jack inner 428, even exist the moisture in the audio jack inner 428 also can pass through the possibility that other moisture invasive channel is invaded media player 10 inside without passage 432.So, confirm that passage that the inner any moisture of media player 10 gets into from external environment condition can provide important data for purpose of design and customer service and contact.Any abuse all can make the quality assurance of any manufacturer become invalid.For example, if the indication that exists moisture to infiltrate media player 10 inside, so reasonably conclusion is that media player 10 once was exposed among the high environment of moisture concentration, in lake, pond or current.Like this, violate the guarantee condition, thereby might have the not cost of repairs within service range.

MOISTURE MEASUREMENT SYSTEM can be set, whether invade media player 10 inside to confirm moisture.But it should be noted that to be expected in the audio jack inner 428 and can have moisture.So the MOISTURE MEASUREMENT SYSTEM of explanation must be distinguished expection and is present in the moisture moisture inner with infiltrating media player 10 in the audio jack inner 428 here.

Figure 18 illustrates the MOISTURE MEASUREMENT SYSTEM 450 according to illustrated embodiment.MOISTURE MEASUREMENT SYSTEM 450 can be positioned at the inside of media player 10.When contact with moisture water content detection layer, through changing color (for example, becoming redness from white), MOISTURE MEASUREMENT SYSTEM 450 can provide the vision indication usually, thereby indication moisture has infiltrated media player 10 inside.MOISTURE MEASUREMENT SYSTEM 450 can be passed through the adhesive layer (not shown), and what be connected to the end 454 that is positioned at audio jack tube 422 checks port 452.Adhesive layer can be any suitable jointing material, such as double-sided pressure-sensitive adhesive film (two-sided tape), adhesive of no backing film or the like.MOISTURE MEASUREMENT SYSTEM 450 can comprise and is connected to the framework 456 of checking port organization 452.

MOISTURE MEASUREMENT SYSTEM 450 can comprise many layers, such as capillary layer 458 and dye layer 460.Capillary layer 458 can be by providing capillarity perhaps to sink another kind of material (moisture in this case) the capillary materials formation of the ability in himself.When drying did not have exterior materials and sinked wherein, capillary layer 458 can have predetermined color.For example, capillary layer 458 can have " non-capillarity " color, and it is generally white, but also can be grey, light color etc.Change color in order to stress when being exposed to moisture under can be provided with the China ink layers 462 that part is covered capillary layer 458.China ink layer 462 can be by painted, setting off by contrast " capillarity " color of capillary layer 458, thereby especially when checking through the little opening of representing with audio jack port 42, provides and better check experience.For example; If " non-capillarity " color of capillary layer 458 is a white; China ink layer 462 can be the white of coupling so, makes when capillary layer 458 changes color, will set off by contrast change in color with the unchanged color of China ink layer 462; Even thereby the little opening through representing with audio jack port 42 also can make change color become more obvious.

In the illustrated embodiment, can be close to capillary layer 458 and arrange dye layer 460.Dye layer 460 can use the dried dye of predetermined color (being generally redness) or coloring material to constitute.When dye layer 460 dryings, capillary layer 458 does not have the capillary ability, so that both keep separating.In case dye layer 460 makes moist or becomes wet, it is wet that dried dye becomes, and get in the capillary layer 458 through capillarity.Like this, capillary layer 458 can become and can see through checking port 452, has the shape of ink receptive layer 462 influences, and wherein dyestuff has the color that forms contrast with the color of China ink layer 462.When not having moisture to infiltrate in the dried dye, through checking port 452, capillary layer 458 shows as has dry color, and such as white, this is because capillarity does not take place.But, when moisture infiltrated in the dried dye, now moistening dyestuff got into and passes capillary layer 458 through capillarity, so that through checking port 452, the color that gets into the dyestuff of capillary layer 458 becomes obvious.In case dyestuff gets in the capillary layer 458 through capillarity, even after capillary layer 458 dryings, dyestuff also can be retained in the capillary layer 458.

Figure 19 illustrates the external view of MOISTURE MEASUREMENT SYSTEM 450.

For the ease of placing audio jack accessory 420 on the PCB 404, can use assembly tool 470 on PCB 404, to support and aim at audio jack accessory 420.Thereby Figure 20 illustrates the panel 472 that is formed by a plurality of PCB that utilize lug 474 to link together.Known in the art, printed circuit board (PCB) is normally with a large amount of preparations of form of a slice that combines with the panel lug or a printed circuit board (PCB).After all suitable circuit and accessory be installed on the tabular PCB, multiple connection technology capable of using such as the welding that utilizes the fluctuation welding procedure, made integrated circuit and accessory be electrically connected with trace among the PCB.But, before connecting technology, can be placed on the PCB 404 at following the audio jack accessory 420 of situation that does not have substantive supporting.Like this, before the welding process or among, the audio jack accessory possibly move, misalignment perhaps otherwise becomes.

Thereby, can use assembly technology 470 to place and audio jack accessory 420 is fixed on each PCB in the PCB panel 472 temporarily.Assembly tool 470 can take to place the form of the pillar of port 48, and said port 48 has makes said pillar can run through the length of audio jack tube 422 (being also referred to as " piercing through ") fully.Like this, assembly tool 470 can be by ledge arrangement 478 and PCB 404 supportings.Like this, assembly tool 470 can support each tabular PCB.Like this, in assembly tool 470 supportings, audio jack accessory 420 can be surface mounted on the corresponding tabular PCB.After mounted on surface audio jack accessory 420 successfully, can remove and abandon assembly tool 470.

Referring now to Figure 21 and 22,, illustrate in greater detail maintained switch accessory 500 among the figure according to illustrated embodiment.Maintained switch accessory 500 can comprise maintained switch carrier 502.Maintained switch carrier 502 can use any suitable elastic material (such as plastics) to form.Intrusion through maintained switch carrier 502 minimizes from the moisture of external environment condition in order to make, and on maintained switch carrier 502, can place maintained switch carrier seal 504.Maintained switch carrier seal 504 can use the waterproof material such as silicon rubber to form.Like this, maintained switch carrier seal 504 can have close-fitting shape in maintained switch carrier 502.In addition, maintained switch carrier seal 504 can have a plurality of openings that allow mechanical actuator to pass through.For example, the opening 506 in the maintained switch carrier seal 504 can hold playlist buttons 44.But; Reduce to minimum in order to make moisture get into media player 10 inner possibilities; The playlist buttons plunger 508 that extends to playlist contact-making switch 412 from playlist buttons 44 can pass maintained switch carrier seal 504 through opening 510; Thereby seal playlist buttons plunger 508 effectively, the feedwater branch stays from external environment condition and gets into media player 10 volume inside hardly.

In order further to reduce the possibility that moisture gets into media player 10 inside; One end is attached to maintained switch button 38, and the maintained switch arm 512 that the other end is attached to maintained switch side startup contact-making switch 414 can pass through to seal the slit 514 that forms in the piece 516 at maintained switch.Maintained switch sealing piece 516 can be formed by the elastomeric material such as silicon rubber, and can closely be engaged in the carrier 502.The pressure that puts on sealing piece 516 can be pressed in silicon rubber on that part of maintained switch arm 512 in the slit 514, thereby appreciable impact arm 512 is mobile.Like this, can prevent that any moisture that is present in hold button 38 from getting into media player 10 inside.

It should be noted that in some cases,, advantageously utilize electric conducting material, mix such as the ping-pong ball shown in Figure 23 518 and seal the silicon rubber of piece 516 from alleviating the viewpoint of ESD.Can provide from maintained switch 38 to through arm 512 to conductive path 520 in the chassics earth portion of shell 100.Like this, can be transmitted to the chassics earth portion that is shell 100 forms at maintained switch 38 or near any electric charge it.But it should be noted that in order good electric contact to be provided, must remove the part surface layer (if any) of decapsidate 100, so that expose metallic matrix at shell 100.For example, under the situation that the aluminium of shell 100 usefulness anodizations forms, thereby the laser-induced thermal etching part 522 of shell 100 can provide good electrical contact for the seal 516 of the conduction of mixing.

Figure 24 illustrates another embodiment of maintained switch accessory 500, wherein between maintained switch button 38 and shell 100, conductive path 524 can be set.Can utilize electroconductive binder to be attached to metal label 40 on the maintained switch arm 512 along the solder line that between metal label 40 and maintained switch arm 512, forms conductive layer 526.Like this, the electric charge on the maintained switch button 38 can be directed into shell 100 along conductive path 524.But, in order to ensure the excellent electric contact between maintained switch arm 512 and the shell 100, the part 114 of the shell 100 that can wear and tear is to expose following metallic matrix (being aluminium in this example).In one embodiment, utilize laser to etch away the superficial layer of appropriate amount, can remove the superficial layer relevant with part 114 from part 114.Like this, maintained switch arm 512 moves, and makes label 38 directly contact with the metallic matrix layer of shell 100 in laser-induced thermal etching part 114.

Should note except good electric contact is set,, make the following soft aluminium of layer of shell 100 be exposed to metal label 38, significantly reduce wearing and tearing and damage label 38 through in part 114.For example; When the aluminium of shell 100 during by anodization; The superficial layer that forms is very hard, reaches following degree, even promptly when label 38 usefulness stainless steels form; Slide repeatedly owing to abut against the superficial layer of aluminium of the anodization of shell 100, label 38 also can or otherwise suffer damage by scratch.But when using laser-induced thermal etching, nature aluminium can not damage or otherwise damage label 38 significantly under the layer of the shell 100 that in part 114, exposes.

Size owing to media player 10 is minimum, aims at the surface part rightly, such as aiming at playlist buttons 44 and shell 100, and can difficulty and time-consuming.Figure 25 illustrates according to illustrated embodiment, is used for installing and aiming at a kind of useful especially technique of alignment of playlist buttons 44 (perhaps any other surface part).Particularly, leave the PCB 404 of the lug 478 of at least a portion above Figure 25 illustrates.Playlist buttons 44 can comprise the plunger 508 that can be pressed on the playlist contact-making switch 412.For the tolerance stack-ups between playlist buttons 44 and the shell 100 is minimized, can with PCB 404 on the relative laser cut line 2502 of fiducial mark 2504, with laser cutting lug 478.Like this, can reduce tolerance stack-ups greatly, thereby significantly improve the impression of playlist buttons 42.

Figure 26 is the block diagram according to the media player 2800 of illustrated embodiment.Media player 2800 comprises the processor 2802 that belongs to microprocessor or controller, is used to control the whole operation of media player 2800.Media player 2800 is stored in the media data that belongs to media item in file system 2804 and the cache memory 2806.File system 2804 generally is a memory disc or a plurality of dish.File system is generally media player 2800 big capacity storage capability is provided.But, since longer to the access time of file system 2804, so media player 2800 also comprises cache memory 2806.Cache memory 2806 for example is the random-access memory (ram) that provides with semiconductor memory.Compare with file system 2804, obviously less to the relative access time of cache memory 2806.But, cache memory 2806 does not have the large storage capacity of file system 2804.

In addition, compare with cache memory 2806, when activating, file system 2804 consumes more electric power.When media player 2800 was the portable electronic device with battery (not shown) power supply, energy consumption was even more important.

Media player 2800 also comprises user and the media player 2800 interactive user input apparatus 2808 that allow media player 2800.For example, user input apparatus 2808 can be taked various forms, such as button, numeric keypad, rotating disk etc.In addition, media player 2800 comprises and can be convenient to the data/address bus 2810 that data between file system 2804, cache memory 2806, processor 2802 and CODEC 2812 at least transmit.

In one embodiment, media player 2800 is used for being stored in file system 2804 to a plurality of media items (for example, song).When user expectation made the specific media item of media renderer plays, the tabulation of available media items purpose was displayed on the display 2810.Subsequently, through utilizing user input apparatus 2808, the user can select one of available media item.When receiving when the certain media items purpose selected, processor 502 offers encoder/decoder (CODEC) 2812 to certain media items purpose media data (for example, audio file).CODEC 2812 produces the audio output signal of giving audio jack 2814 subsequently, so that export to external circuit.For example, head phone that is connected with media player 2800 or earphone can be counted as the example of external circuit.

Figure 27-29 shows according to illustrated embodiment, the utmost point and is suitable for being formed for technology and the structure that the moisture of audio jack accessory 420 gets into seal.Although it should be noted that about audio jack accessory 420 to describe, illustrated technology and structure almost can be used for any equipment of operating and construct with following mode, and promptly at least a portion is water-fast, and approaching another part must keep not water-fast.A good example of this situation is an audio jack accessory 420, and wherein tube 424 inner chamber 428 must be water-fast, because audio port 42 is exposed to external environment condition having no under the pretreated situation.For example, portable electronic device 10 possibly be immersed in the liquid of water for example, makes water electrode to get into inner chambers 428 (supposition does not obviously have the audio frequency terminal to be inserted in the audio jack tube 422) through audio port 42.In inner chamber 428, exist water no problem usually, but moisture invasive channel 432 can provide a kind of mechanism, the water that in inner chamber 428, exists thus can get into the inside of media player 10.

Therefore, must be effectively and make the water admission passage 432 that effective and efficient manner prevents in inner chamber 428, to exist effectively (perhaps to any other passage of this problem) with cost.A kind of useful especially means of closed cavity 428 rely on and form hermetically-sealed construction, and it stops moisture to move from the inside of inner chamber 428 and media player 10 effectively.In one embodiment, hermetically-sealed construction can be used for sealed electrical contact site 430.The electrical contacts hermetically-sealed construction can form and comprise primary seal and the follow-up finishing seal that applies.In one implementation, primary seal can be formed by the sealing belt of a part that is applied to electrical contacts and audio jack shell through pressure.After forming primary seal, can, electric connector form the finishing seal in being electrically connected to the attached processing of assembly of expose portion of electrical contacts.The attached processing of assembly can be adopted various ways.But in the illustrated embodiment, the attached processing of assembly can be adopted the form of mounted on surface assembling (SMA) technology.A kind of useful especially SMA technology that is called solder reflow depends on the heating soldering paste relevant with flexible connector and forms liquid solder.Liquid solder then can be in the engaging zones of the expose portion of flexible connector and electrical contacts and near mobile.When allowing cooling, liquid solder is solidified in position, between flexible connector and electrical contacts, conductive path is provided by means of expose portion.The scolder that solidifies can also be sealed in the zone between the expose portion of band and electrical contacts.Like this, scolder can provide the mechanism that form to be electrically connected and to seal this electrical connection, thus the cost that provides the utmost point to be suitable for improving to prevent water intrusion media player 10 effectively with make valid function.
