Description
Technical field
The present invention relates to technical field of electronic products, and in particular to a kind of improvement of microphone waterproof assembling structure and has
The smart electronics product of the structure.
Background technique
Rise and universalness with electronic products such as smartwatch, the upgrading of wearable device especially in recent years,
The waterproof and dustproof performance of the electronic products such as smartwatch is higher and higher.
Currently, smartwatch microphone waterproof be usually pass through on shell paste one layer of translucent film of waterproof (abbreviation waterproof membrane) into
Row waterproof, and waterproof membrane is placed directly against by housing sidewall using double-sided adhesive and carries out waterproof and fixation, but because of waterproof membrane thinner thickness
And without the structure of protection support, can be only applied in shallow water or life waterproof product.At product waterproof requirement height and product
It is worn when deepwater environment, such as when diving, waterproof membrane will receive larger or powerful hydraulic pressure at this time, and waterproof membrane is in hydraulic pressure
Effect is lower to generate different degrees of deformation, and when especially hydraulic pressure is big, deformation is even more serious, so that the translucent effect of waterproof membrane
It can fail and lead to not transmit sound, meanwhile, the gum of waterproof membrane also will receive powerful hydraulic pressure effect and be stripped, Jin Eryin
Waterproof failure is played, and then makes damage of product, poor user experience.
Specifically, existing smart electronics product microphone waterproof assembling structure generally include shell, waterproof membrane, stiffening plate,
Circuit board (FPC or pcb board), microphone composition, waterproof membrane front and back sides are carried on the back double-sided adhesive, are assembled on shell, by its one side
Double-sided adhesive fixed with shell, stiffening plate and microphone, circuit board constitute a circuit board assemblies together, pass through waterproof membrane another side
On double-sided adhesive be commonly assembled on shell, so that waterproof membrane be made to be folded between circuit board assemblies and shell.
The prior art has the following disadvantages and deficiency: waterproof membrane is only through gum and is assembled on shell, in deepwater environment
When waterproof membrane is by larger or powerful hydraulic pressure, waterproof membrane is acted on by hydraulic pressure can generate different degrees of deformation, to make
It obtains the translucent effect failure of waterproof membrane and leads to not transmit sound, meanwhile, the gum of waterproof membrane also will receive powerful hydraulic pressure
It is stripped under effect, and then causes waterproof failure.
Summary of the invention
The present invention provides a kind of microphone waterproof assembling structure and smart electronics product, can solve waterproof in the prior art
