Description

The anti-water dust structure of hand-held moving device

Technical field

The utility model relates to a kind of anti-water dust structure of hand-held moving device; Refer to especially, the water proof and dust proof structure of electroacoustic assemblies such as the microphone of hand-held moving device and loudspeaker, and in the casing of hand-held moving device, inject liquid-state silicon gel curing sealing, think to prevent that water dust from immersing the structure in the hand-held moving device.

Background technology

The hand-held moving device of Shi Yonging (for example: intelligent mobile phone now, flat computer, digital photo frame, e-book, electronic products such as AV device) the audio-visual multimedia function of video signal increased and active daily life on many convenient effectiveness, cause that to carry the dependence day of using everywhere indispensable with increase; So, fail safe at the hand-held moving device environment for use has risen to functions of waterproof and dustproof, with reference to Fig. 1, mobile phone shown in 2 is example, microSIM draw-in groove 11 and microUSB port one 2 with casing 1 side wall, and micro memory draw-in groove 13 and earpiece holes 14 etc. are all set O-ring seal 21 removable sealings in the waterproof cover 2 with correspondence and are appeared, reach the intrusion of avoiding moisture content and dust when making capping, and power switch button 15 and volume are adjusted button 16 or the camera lens 17 of taking pictures, the button 171 of taking pictures, photoflash lamp 172 or video signal camera lens 18 etc. also have the structure of doing waterproof sealing to handle, still to battery 3 envelopes are put in casing 1, make and expose charging contacts 31 and can be located in ad hoc cradle and supply with accumulate (aforementioned cradle is the commonly use skill of each label in response to different designs, will not be in giving unnecessary details at this, figure does not also illustrate), mostly adopt no frivolous formation sealing backlight to be arranged on casing 1 front as for 4 of screens, constitute 5 with the electronic circuit of establishing in the casing 1 and directly link, make hand-held moving device have the effect of water proof and dust proof; The microphone 6 that casing 1 sound hole 19 exposes and loudspeaker 7 then just are isolated extraneous moisture content and dust with the sealing effect of its radio reception vibrating membrane 61 and sounding vibrating membrane 71, though have the effectiveness of water proof and dust proof, the invasion of the immersion of extraneous water and block dust is real dislikes improper slightly but directly block with the vibrating membrane of radio reception or pronunciation, easily makes vibrating membrane impaired and aging or reduce its usefulness.

The utility model content

The technical solution of the utility model is:

A kind of anti-water dust structure of hand-held moving device, include the functional unit of most operations of casing appearance group, the removable sealing of corresponding waterproof cover is set or appears at enclosure wall, and each functional unit and battery, screen, microphone, loudspeaker etc. are that the electronic circuit that directly links hand-held moving device constitutes being set in the casing of driving fit, and in microphone, sealing is embedded the oscillation of sound pressure frequency of a vibrating diaphragm water proof and dust proof and the transaudient sound that is situated between between loudspeaker and casing shell wall sound hole, and fill in silica gel at each functional unit, electronic circuit constitutes, battery, screen, and the clearance cure between casing, make formation one sealant layer make hand-held moving device have water proof and dust proof effectiveness.

Because the utility model adopts the anti-water dust structure of above-mentioned hand-held moving device, make the microphone of hand-held moving device and loudspeaker certain have a water proof and dust proof effect, more with low tension stress, non-conductive magnetic, do not have adhere to put forth effort, the liquid-state silicon gel of high heat radiation, soaking-resistant is solidified into the sealant layer bag and protects each functional unit, and can easily give in rejecting and heavily spread silica gel with the assembly of replacing or quarantee device inside, make hand-held moving device more become convenience and fail safe, and further promote the benefit of hand-held moving device.
